What are the conditions required for high-quality precision parts processing

Precision parts processing technology and stamping molds should be closely combined with the actual situation of the factory machinery, staff, etc., and comprehensively consider the quality, productivity, manufacturing costs, labor efficiency, environmental maintenance and safety factor of manufacturing, and determine and design them. Production technical solutions and mold design with excellent technology, economical and reasonable application are safe and reliable, so that stamping parts production can be minimized on the basis of ensuring that they meet the technical standards mentioned in the design drawings, and ensure that the production of stamping products is achieved. Production safety. Today, Dongguan Ruibang Technology will introduce to you the necessary conditions for high-quality precision parts processing.

Performance requirements for precision parts stamping parts

(1) Standards for precision stamping parts

To meet the accuracy standards of stamping parts, the production process volume must be determined through the design and calculation of the stamping mold. This is not only because it involves factors such as material characteristics, depth drawing height, and the number of deep drawing steps, but also depth drawing. Diameter, material thickness and other conditions.

(2) Requirements for fine machining of stamping parts

Regarding the fine requirements of stamping parts, the number of processes depends on the complexity of their structural shape. Therefore, it must be determined based on factors such as the number of bending angles, relative position and bending direction.

(3) Standard for aesthetics of stamping parts

After the stamping process meets the requirements of precision and fineness, the beauty of the workpiece becomes a new production process standard. When the cross-sectional quality and specification requirements of stamped parts are high, you can consider adding the finishing process after the stamping process, or directly selecting precision stamping to increase the value of the refined stamping parts.

Production and processing technology of two precision parts

(1) Part drawing

The design analysis of parts and stamping dies is based on part graphics. By analyzing the basic elements of the part shape characteristics, specifications, precision standards, raw material sizes and tensile strength, the stamping machine specifications and mold processing conditions of existing parts are used. , manufacturing batch and other basic elements, analyze the stamping processability of parts.

(2) Clarify the process plan

Based on the stamping process analysis, standardized analysis of technical parameter calculations is carried out from the aspects of equipment occupation, the level of difficulty coefficient and life of mold processing, the degree of convenience and safety of use, and the screening of existing production processes and mold designs is selected. The characteristics and key points of the company include process flow characteristics, production process quantity, process sequence and composition form, etc., and clarifies appropriate plans suitable for the current production standards.

(3) Determine the production process parameters

Product technical parameters refer to the data based on when formulating process plans, such as various forming coefficients (stretch coefficients, expansion coefficients, etc.), the stretching specifications of parts, as well as their impulse and forming forces, etc. There are two situations in the calculation process. One is that the process parameters can be calculated more accurately, such as the raw material application rate, cutting pressure center, workpiece area, etc. when the part is arranged; the other is that the process parameters can only be calculated approximately, as in general Bending or drawing forming force, miscellaneous parts blast material expansion specifications, etc.

(4) Selection of punching machine

According to the characteristics of the stamping process to be carried out by the punching machine and the force and energy characteristics of various punching machine tools, the specific principles of deformation force, deformation work, height, width and height of mold closure ratio and appearance specifications required for forming are in line with the company In the current mechanical conditions, reasonably choose the mechanical model and tonnage.

Selection of stamping oil for precision parts processing

Die-casting oil plays an important role in the die-casting process. Good cooling characteristics and extreme pressure wear resistance are of great significance to extend the service life of the mold and to improve the precision of the workpiece.

1. Selection of low carbon steel plate stamping oil

When choosing stamping oil for carbon plates, the first thing to pay attention to is the viscosity of the stretching oil. Determine the optimal viscosity of the product based on the production process difficulty coefficient and degreasing standards.

2. Selection of galvanized steel plate stamping oil

Because chemical reactions with chlorine additives, you should pay attention to when choosing galvanized steel sheet stamping oil. Chlorine stamping oil will cause white rust and degreasing as soon as possible after stamping.

3. Choice of stainless steel stamping oil

Stainless steel is prone to hardness, and it is required to use an oil film, which has high strength and good sintering resistance. Generally, stamping oil containing sulfur-chlorine mixed additives is used to avoid problems such as burrs and cracks in the workpiece and ensure extreme pressure performance.

The precision of finishing is very high, so when choosing a precision parts processing manufacturer, it is necessary to look at the comprehensive strength of the enterprise, including the overall technical level of the production and processing equipment and the operator, so as to ensure that the workpiece meets the prescribed requirements.
