Stamping process

 

The metal stamping process can be divided into two major categories: separation process and forming process. The purpose of the forming process is to plastically deform the sheet without breaking the blank to form a workpiece of the desired shape and size. The separation process is also referred to as blanking, and its purpose is to separate the stamped parts from the sheet along a certain contour line while ensuring the quality requirements of the separated sections. In actual production, it is often the case that multiple processes are integrated into one workpiece. Blanking, bending, shearing, drawing, bulging, spinning, and correction are several major stamping processes.

 

1. Process drawings for designing processed parts

Design and draw three parts of the hardware artifact, the role of which is to express the structure of the sheet metal part by drawing. Draw the unfolding of the workpiece, which is to expand the complex part into a flat part. Analyze the part drawing, quickly understand the workpiece size, coordinate point, line, curve and cutting surface position relationship, determine the workpiece coordinate origin, calculate the coordinates of each vertex and the coordinates of the curve joint.

2. the correct process

The choice of workpiece surface processing method is to select a reasonable processing method for each surface with quality requirements. Generally, the final processing method is selected according to the requirements of surface precision and roughness, and the processing method of the preparation process before finishing is determined, that is, the processing scheme is determined.

3. the cutting method selects high efficiency

The underside of the scissors is the length and width of the scissors shape. If there is an angle of attack and a chamfer, the punching is combined with the punching of the die to form a chamfer. The underside of the press is a flat sheet structure that is used to rinse the part after one or more steps have been deployed. The advantages are short working hours and high efficiency, which are often used in batch manufacturing. Use the programming software to write the drawing extension as the identifiable content of the CNC machine. Let it be programmed to cut the structural shape of its cutlery. Laser finishing is a structure that uses laser cutting to cut the shape of a plate on a board.

4. develop the stamping sequence

Generally, there are processing procedures such as punching angle punching, punching convex hull, punching tearing, pumping, etc., and the processing requires a corresponding mold to complete the operation. In addition, the bending process requires a bending bed and a corresponding bending die to complete the operation. The design principle is to give priority to the next step without interference.

5. complete the fastening parts process

Generally, the operation is completed by a stamping riveting process or a hydraulic riveting machine, and the fasteners are riveted on the sheet metal parts, and the pressure riveting is commonly used in pressure riveting bolts, compression riveting nuts, pressure riveting screws, and the like. The process of flanging taps is to dig a slightly larger hole in the smaller bottom hole and then suck the faucet hole. This can increase its strength and avoid sliding teeth, which are generally used for workpieces with a high thickness of the sheet. When the thickness of the sheet is large, it is not necessary to directly tap the tapping.

6.parts assembly method

Welding welds multiple components together for processing purposes or individual component joints to increase their strength. The surface treatment usually has a phosphate film, electroplated polychromatic zinc, chromate, baking varnish, oxidation, and the like. The choice of specific surface treatment methods is based on demand. Assembly assembles multiple parts or assemblies in a way that makes them a complete project.

 

Custom metal parts requirements

 

The drawings are provided by the customer, and the manufacturer uses the equipment to produce the corresponding products according to the drawings. Usually, the molds are mostly, the tolerance requirements, and the finish are all specified by the customer, and there is no certain paradigm. The product requires complete quality control from casting to finishing, the process is complex and variability, and the general cost is higher than the standard parts.

 

Tolerance values applicable to part dimensions may affect the molding method used. Therefore, when drawing definition maps, it is recommended to work with the foundry to determine: recommended dimensions and required precision; machining requirements; molding methods; number of parts to be produced;

 

The precision of the die casting process depends on several factors, including: dimensional complexity; mold category; metals and alloys used; mold conditions; foundry work methods.

 

Summary

 

It's helpful to know a little about your process before you choose any company to custom metal parts. Tell them your needs, they can better custom metal parts for you.
