1. Kunshan stamping die supply data and heat treatment control.

In the heat treatment of mold parts, the parts are assembled together to reach the hardness of data, so that the processing process and the specification of forming parts are safe. Considering the structural characteristics of data and different parts of parts, different heat treatment methods are selected. In the heat treatment process, some internal pressure of heat treatment is used to control the heat treatment process, considering the hardness of thermal resistance and the sensitivity without carbonization Sensibility, the thin-walled part of the cooling process should be selected.

In addition to selecting CrWMn, Cr12, 40g, GCr15, Cr12MoV, 9mn2v carbides, there are some working strength, strength of rigid mold, stamping, which can be used for high heat stability, as well as alloy steel S2, S3, V10, aps23s1, G3, G3, G3, G4, G4, G8, etc.

(2) After the pressure treatment after quenching of Kunshan stamping die, there is pressure on the workpiece. After the change of working parts and the pressure of cracking, the short-term invasion after processing should be hot. These areas should be hot. These areas should be after quenching, and the pressure of pressure reduction should be removed by the method of shape and disorder, and the temperature will not reach the pressure elimination Finally, pressure release or repeated aging and pressure release need to be handled.

2. Kunshan stamping die supply grinding process.

Grinding is the key process of Kunshan stamping die supply. After all, the grinding process should be strictly controlled by grinding deformation, grinding cracks or even micro cracks on the surface of the workpiece. In the process of precision grinding, the following aspects should be considered.

(1) Selection of grinding wheel: mould data of high tungsten, high vanadium, high molybdenum, high alloy and high hardness can be selected. Chrome inlaid steel jade grinding wheel and GC green silicon carbide grinding wheel can be selected. In the process of processing solid alloy and high strength data, as well as grinding wheel with organic adhesive, and using organic binder grinding wheel, the hardness is higher than it, and the roughness is 0. 16. CBN cubic borax is used in CNC machine tools, hybrid grinders and CNC surface grinders, better than other grinding wheels. In the process of grinding, the grinding wheel, sharp wheel, and passivation wheel in the process of processing can slide, press and knead the surface of the workpiece, forming the surface, micro cracks or grooves of the burning operation parts, affecting the processing accuracy.

(2) Feed selection: the supply of stamping die for precision grinding Kunshan is small, and the cooling time is high in the grinding process. When selecting coolant medium, the machining allowance shall be kept at a stable temperature of 0.01mm.

(3) Workpiece equipment: the characteristics of shaft components are composed of many surface modifications, usually using precise processing methods in the slow mechanical grinding process, using the grinder, fixed on the top at the end of the fixed equipment, on the top of the workpiece, the top of the top is the top of the grinding part, in the center of the grinding part, in the center of the grinding part, the processing alignment can not reach Therefore, in the treatment of chuck and the test of the center of the first trap before and after drilling, it is necessary to consider the process of selecting interlayer in this book, that is, in the process of processing, the thicker wall is on the left, and after the intact cutting, the inner hole is on the ground.

3. EDM operation.

(1) Line cutting and preparation, power selection for fine line cutting, machining accuracy + / - 0. 1100mm, raz = 0。 2. Select the ions supplied by Kunshan stamping die, cut them directly into the appropriate processing precision, and cut the materials with silk, so that the workpiece can be processed at the appropriate speed.

(2) Processing road design: in the process of processing damage, block the original pressure balance data, use the principle of vector translation under the pressure environment of the corner, before rehearsal, processing and heat treatment, use the principle of vector translation, then heat treatment, and then processing, to ensure the safety of safety behavior. Four times in the processing process, cut to the direction, a reasonable selection, in the first time after eating, the part of the operation is not hung on the wall, the pressure is always part of the follow-up processing, does not affect the end; the blank is perforated, the operation is also cut into small pieces.

(3) EDM process: it is necessary to make thick electrodes for EDM. With CNC machine tools, copper-w alloy electrode has outstanding induction function, rather than the current copper electrode waste. In the case of chip removal, it is very difficult to deal with the shape and disorder of data and cross section; Ag-W alloy electrode is superior to copper tungsten alloy electrode for precision machining. Graphite electrode is imported graphite, low loss, high hardness, fast etching speed and low surface roughness. Before EDM discharge, it is necessary to develop a stop procedure to remove the outer hardened layer.

4. Kunshan stamping die supply appearance processing and processing equipment.

In the process of machining, there are no holes, uniform hardness and low homogeneity. The inclusion of the part and the appearance of the part are not assembled in a stress part, such as a ground crack. Polishing, grinding, polishing, grinding, polishing, processing the blunt edge, 6-10 meters of deformation hardening layer, a layer of crispy, the remaining pressure, the use of energy before the removal of hardening layer, this is a very useful solution.

(2) Before assembling, a large number of handicrafts, ethyl acetate, can be magnetized, magnetized and weakly magnetized in the grinding and sanding process of Kunshan stamping die supply. In the adsorption process of short sun, fully understand the structure and process requirements of the equipment and the end of various components; the equipment of each component is correct. Check the share accuracy of each part and clarify the requirements of harmony; equipment matching; first, the modular part of the conduit and the installation of the cavity; the combination of the combined plate and the punching, adjust the direction of each plate; open the mold to see if the mold action is accurate and reliable.
