Online cutting process analysis

The cross-section of the plasma laser cutter is not only closed but also complicated. The plasma profile closed section is composed of a vertical surface, a horizontal surface and a curved surface, and the material is a galvanized steel sheet of 1.25 mm. It is required to ensure not only the quality of the section but also the galvanized layer and the speed of the production line. This brings a lot of trouble to the mold design. If the conventional cutting die is used for the overall cutting, it will not be cut off, and the product requirements cannot be met. According to the characteristics of the parts, a deep analysis is made, and it is decided to reserve a cutting amount of 6.8 mm before cold forming. Because the shape of the part is very special, the edge of the punch must be shaped, not only to cut the curved surface, the horizontal surface, and the vertical surface, but also to have no sag and scratches. According to the process requirements, in order to prevent the sag and ensure the convexity Intensity, it is decided that the process hole should be pre-punched in the middle of the part and at the corner, and the pre-punching hole must be punched out before forming, that is, before the cold bending, a process is added - pre-punching, so a pre-punch is designed. Hole mold. That is, two sets of molds are required to cut the workpiece: a set of pre-punching dies and a set of cutting dies.

Pre-punching the design

1. Position determination of mutual pre-punching

From pre-punching to cutting, there is a forming process in the middle, so that the position of the pre-punching is more complicated. Not only to ensure the quality of the cut surface, but also to choose the right position to improve the strength of the die of the cutting die, and also to ensure that the cold forming of the cutting die is not affected, and according to the requirements of the stamping process, the hole of the punching part The distance between the holes and between the holes and the edges should not be too small to correct the position of the holes and repeatedly simulate through the computer. The hole in the middle portion is to ensure that the intermediate portion of the punch is not too long and too sharp, and the formed chips are easily discharged when the top of the workpiece is punched. The hole at the corner is to ensure that there will be no sag at the time of cutting, and at the same time, it will not produce chips that are difficult to discharge.

2. Unfolding of the workpiece

Directly use the Pro/E expansion command to expand the part to get the expanded view. Expand the Expand Create Sheet Metal Unbend Regular by expanding the command, select a datum plane or edge (unmoved or edge) when unfolding, then select the Unbcnd All command, and then click OK.

3. Structural design and working process analysis of pre-punching die

①Pre-punching die structure design

According to the unfolding diagram and precision requirements, the diagonal guide column formwork is selected, and the formal form is adopted, the punch is on the upper side, and the concave mold is on the lower side. For economical processing and easy maintenance and replacement, the male and female molds are in a block-like structure, so that the insert can be replaced without removing the entire mold. After the two punches and the punch fixing plate are fixed, they are directly fixed on the upper mold base 7 by screws together with the punch pad, and the two concave molds are symmetrically set in the lower mold base.

In order to prevent the sticking of the scrap, the unloading rubber is specially designed on the punch, and after the scrap is punched off, the scrap is smoothly separated from the convex and concave molds under the elastic force of the rubber. In order to reduce the labor, the edge portion is made 1. S0 slope. In addition, because it is an online automatic production, the strip is automatically fed, so a fixed discharge plate is adopted, so that the discharge plate not only functions as a discharge plate but also functions as a guide plate, and the fixed discharge plate has a discharge force. Large, simple structure. Single features.

②Analysis of the working process of pre-punching die

In the working process, the plate guides the guide plate (the guide plate and the discharge plate 3 are the same plates), and the feeding process is automatic feeding, and the punching position is determined by the photoelectric switch. The plate is taken to the proper position. Under the action of the hydraulic machine, the upper mold base drives the punch downward, and the punch starts to work. Under the joint action of the convex and concave molds, the punching is completed. Under the elastic force of the rubber, the waste is smoothly leaked from the leakage hole, and the punch is lifted up, and one stroke is completed.

Decking creating time of year in many parts of the country is quick and fairly sweet, which means that composite decking contractors have to optimize effectiveness and lower job-website time. Put simply, complete tasks more quickly.

Listed below are 6 methods for getting more composite deck jobs completed in 2019 and much more funds in the before the period ends.

1. Install Capped Composite Decking

Contractors who choose capped high profile composite decking for his or her clients can full careers faster because when the decking is connected to the structural framing, there’ s no need to return within the job. Say goodbye to time wasted waiting around for the elements to cooperate for sanding and discoloration. The hard-outside shell of most capped composites also enables crew members simply to walk over the deck surface with little worry of harm.

Some composite decking suppliers such as Oakio go a step further by wrapping a protective movie around each board. Right after the last decking element is put in, builders can easily remove the film and expose a beautifully unmarred surface for the home owner.

2. Use Color Matched up End Caps Instead of Image Framing

Before, home owners have typically opted to “picture frame” their decks, since they experienced hardly any other option. This required contractors to install additional joists and supports to basically hide the ‘butt ends’ of the structure in a way that was also structurally sound.

Although successful, image framing the perimeter of any deck costs time, labour and components – especially on custom made composite deck installation that include many perspectives and/or numerous ranges. Nowadays, composite companies provide shade-matched up end caps that easily and quickly connect to the cut comes to an end of every deck panel. This is not just much more economical for the customer, in addition, it provides for a simpler, better framing system to become put in under.

3. Cable television Rails Are Faster & More Appealing for Clientele Than Balusters. Pre-Drilled Rail Posts Make the Job Faster.

For any more modern day, streamlined look, property owners have opted to put in cable tv rails instead of standard balusters. While the result may be virtually unobstructed sights for that home owner, the precise dimensions needed to get every single hole drilled at your location could be a time-consuming, neurological wracking challenge for deck building contractors. Rather, go for railing techniques that offer articles with pre-drilled openings. That way, your crew can confidently (and quickly) install composite articles and string the cable connections as simply as lacing up a footwear.

4. Use a Concealed Fastening Method

Can there be anything at all more tedious and time-consuming than including plugs to pay for the screw heads of literally hundreds of fasteners used on a job? Why not make 2019 the entire year that you simply start using a hidden fastening method as an alternative? Not only can the outcome supply property owners with a clear, uniformed surface, deck building contractors will be able to complete the installation in two enough time, as well.

Combined with the streamlined look, some hidden fastening techniques provide additional, time conserving advantages for decking benefits. As an example, the Step-Clip program from Oakio is made to not only attach quickly and easily to your framing joist, additionally, it provides a accurate, uniformed area between each composite deck board. This reduces the requirement to put in plugs and pre-spaces boards in a manner that indicates to reduce put in occasions up to 50% – for both knowledgeable building contractors and novice DIYers.

5. Produce A Plan with Customers In Advance

As they say, “an ounce of elimination may be worth a pound of cure.”  It can’t be stressed enough how essential it is to get as many specifics as you can resolved using the customer before building of the new composite deck starts. Carefully introducing, analyzing and documenting elements of the project with home owners beforehand will help steer clear of expensive and time-eating miscues once work begins. An excellent pre-construction program also permits builders to pre-purchase supplies and synchronize shipping and delivery in a way that is best.

6. Purchase Pre-Reduce, Custom-Size Boards for Large Work.

Determining twice and slicing once is traditionally the way that all craftsmen steer clear of making blunders. Although a powerful approach, this process can be time-consuming. Especially when you add inside the time for you to walk backwards and forwards from the measurement area to the cut site.

Instead, wise deck builders save time by partnering with reliable suppliers and vendors to accomplish the measuring and slicing on their behalf. This turns into a crucial element to completing large composite decking installations faster as well as makes developing several decks (to get a new subdivision community or condo connection) a breeze, too. Oakio delivers the service to companies, at no extra cost, on orders of 200 composite decking boards or even more.

With regards to deck creating, particularly in a area with short periods, the key to success is discovering and incorporating new methods into your business to minimize squander, save time, improve high quality and make more money. Hopefully these pointers will help you put in composite decking faster and easier, as well as for your organization to finish more tasks inside the forthcoming calendar year.
