Problems solved by technology

However, the existing stamping process still uses traditional methods, and even uses experience to design the stamping process. Over the years, experience has been used without technological innovation, which severely limits the development of stamping production and also causes a great waste of raw materials.

Embodiment 1

[0022] A stamping process for improving the step retention rate of stamping parts, including the following steps:

[0023] (1) Collect and analyze the original data of stamping parts design. The original data of stamping process design include: product drawings and technical conditions of stamping parts; size specifications, performance and supply status of raw materials; production batches of products; existing stamping in the factory Equipment conditions; the existing mold manufacturing conditions and technical level of the factory;

[0024] (2) The stamping process analysis and review of stamping parts. The stamping process analysis of stamping parts is based on the product drawings of the stamping parts. The shape characteristics, size and accuracy requirements of the stamping parts are carefully analyzed and studied, and the stamping performance of the materials used During the analysis, attention should also be paid to the special requirements of the limit dimensions, dimensi...

Embodiment 2

[0031] The step retention rate of 57462 stamping parts used on Toyota 930L car body is improved. Before the improvement, the reserved thickness of stamping parts on the steel plate is 1.6mm, the length is 1150mm, the width is 340mm, and the total weight is 4.91Kg. Process method, after the improvement, the reserved thickness of the stamping part on the steel plate is 1.6mm, the length is 1135mm, the width is 335mm, and the total weight is 4.77Kg. Each piece saves 0.14Kg of material. The material used in this stamping part is SPC270E. Based on the monthly production of 3000 pieces at 6 yuan per kilogram, it can save 420Kg of steel per month and 5,040Kg per year. This saves 30,240 yuan per year for the stamping part alone; and the mold modification fee is only 300 yuan. Through this process, the manufacturing cost of stamping parts is reduced, and the income is increased.

Embodiment 3

[0033] The step retention rate of No. 52171 stamping parts used on Toyota 930L car body is improved. Before the improvement, the reserved thickness of stamping parts on the steel plate is 1.8mm, the length is 260mm, the width is 1085mm, and the total weight is 3.986Kg. Process method, after the improvement, the reserved thickness of the stamping part on the steel plate is 1.8mm, the length is 255mm, the width is 1085mm, and the total weight is 3.9Kg. Each piece saves 0.086Kg of material. The material used in this stamping part is SPC590DU. Based on the monthly production of 3000 pieces at 7 yuan per kilogram, 258Kg of steel can be saved every month and 3096Kg per year. The stamping parts alone save 21672 yuan per year; and the mold modification fee is only 300 yuan. Through this process, the manufacturing cost of stamping parts is reduced, and the income is increased.

Abstract

The invention discloses a stamping process for improving the retention rates of stamping parts. The stamping process comprises the following steps: (1) collecting and analyzing the source materials of stamping part design; (2) analyzing and investigating the stamping manufacturability of the stamping parts; (3) establishing a stamping process scheme; (4) selecting a rotary mould type; (5) selecting stamping equipment; and (6) compiling a stamping process file. The stamping process disclosed in the invention abandons the experience design and strictly adopts programmed process flows, so that the retention rate of the stamping part production is greatly improved.

Description

Technical field [0001] The invention belongs to the field of stamping process design, and particularly relates to a stamping process for improving the step retention rate of stamping parts. Background technique [0002] In my country's automobile industry, more than 60% of the parts of the car itself need to be stamped. The small reflector outer plate to the whole car shell need to be stamped to varying degrees. Stamping is widely used in the automobile manufacturing industry for its high efficiency, energy saving and low cost. The rapid development of the automobile industry is inseparable from the development of the stamping industry. [0003] In the stamping process design, the retention rate refers to the ratio of the quality of the input sheet to the quality of the finished product. Under the premise of not affecting the quality of the finished stamping parts, it is the goal of all stamping parts manufacturers to minimize the quality of the input plates to achieve the effect ...
