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.

Safety measures to be taken when handling the wire straightening and cutting machine

(1) When handling the wire straightening and cutting machine and installing the bearing frame, the center line of the bearing frame groove should be aligned with the guiding tube, and the center line of the straightening tube and the lower cutting hole.

(2) After installation, check the electrical system and other components for damage, whether the wire straightening cutting machine connection parts are firm and reliable, and whether each transmission part is flexible. After confirming that every part is normal, the test run can be performed. The bearing temperature should be checked during the test run to see if the workpiece such as the hammerhead, cutter and shear gear is in normal condition. Only after confirmed that there is no abnormal condition can the material be fed, the straightening test is run and the wire is cut off.

(3) Select the appropriate straightening block, the traction sheave groove, and the transmission speed according to the diameter of the reinforcing bar required to be straightened. And the diameter of the straightening block should be 2mm~5mm larger than the diameter of the reinforcing bar, and the width of the traction sheave groove should be consistent with the diameter of the reinforcing bar required to be straightened.

(4) Care must be taken to adjust the straightening block. In the straightening tube, there are generally five straightening blocks. The first and fifth straightening blocks must be placed on the centerline, and the middle three can be off centerline. First, shift the steel bar by an offset of about 3 mm. If the reinforcing bar still has a slow bend after the straightening test is run, the offset can be gradually increased until it is straightened.

(5) A steel pipe with a length of about 1 m should be installed at the front of the guide cylinder. The reinforcing bars to be straightened should pass through the steel pipe first, then penetrate into the guiding cylinder and the straightening cylinder to prevent the end of each reinforcing bar from popping out and causing hurt to people when the straightening is nearly completed.

• Before the straightening block is fixed well and the protective cover is on well, the reinforcing bar shall not be inserted to prevent the straightening block from flying out to injure people after the machine is turned on.

In recent years, the wafer industry has developed rapidly, but at the same time, it also produces a large amount of wastewater. The production wastewater mainly comes from the cleaning process of the polysilicon ingot slicing process. The acid-containing wastewater is produced in the cleaning process after the surface treatment of the polycrystalline silicon ingot with the mixed acid. Since the surface treatment is a mixed acid of nitric acid + hydrofluoric acid, the main pollution in the washing wastewater is pH, fluoride, and nitrate. The organic wastewater is produced in the cleaning process of the sliced polycrystalline silicon wafer. Since the cutting fluid (the main component is polyethylene glycol) and the cut micro powder (the main component is silicon carbide) are used for slicing, the main pollutant in the cleaning wastewater is CODCr and SS.

Polysilicon cutting fluid is made up of polyethylene glycol as the main body and added with various additives. It has a suitable viscosity index, good fluidity, and thermal conductivity, and has good dispersion stability and suspension effect on silicon carbide micropowder. A large amount of waste liquid is generated after cutting, and the waste liquid contains a considerable amount of polycrystalline silicon powder, which has a certain recovery value. The polysilicon powder is recovered by the ceramic membrane separation technology, becoming the so-called cutting fluid recovery. And the site is clean and sanitary, which is in line with the national energy-saving and emission-reduction industry orientation.

Ceramic membrane equipment technology is advanced and mature, with low operating costs and fast return on investment.

Ceramic membrane filtration process can directly deal with the waste liquid containing silicon produced in the solar energy production process, collect silicon, reuse pure water and coolant.

The process can separate silicon powder and pure water, recover over 98% of the silicon powder, reuse more than 90% pure water,reuse about 50% of coolant and shaping agent , which can greatly reduce the load of the sewage station.

The process has the advantages of short process, simple operation, short payback period, and has become the preferred standard process for the benchmarking enterprises in the silicon chip industry.
