Problems solved by technology

The cycle required for such a round will take about 80-100 days, and there is no room for more cost savings, which has caused a great economic burden to automakers and parts suppliers.
And the parts produced by high-cost trial production may also lose the timeliness of competition with other brands due to cycle reasons

Embodiment 1

[0027] Embodiment 1: see figure 1 , in the prior art, the complete stamping process of the parts includes: forming, trimming and punching, flanging and hemming. from figure 1 It can be seen that the mold to be used includes an upper die base 1, a lower die base 2, an upper molding insert 3, a lower molding insert 4, an upper trimming insert 5, a first presser 6, a lower insert 7, a turning Edge insert 8, top piece 9, flange lower insert 10, edge wrapping upper insert 11, second presser 12, punching punch 13, punching die 14, etc.

[0028] In the prior art, when designing the upper mold base 1 and the lower mold base 2, it is necessary to consider the traditional positioning and connection fastening factors required to connect with the mold base. The plate groove is clamped and fixed with the machine tool.

[0029] The trimming of the traditional stamping process needs to fix the upper and lower trimming inserts after processing to the upper and lower mold bases 2 respective...

Embodiment 2

[0034] Embodiment 2: the process of the present invention see figure 2 A kind of heat insulation sample sample car sample processing method, comprising the following steps:

[0035] (1) Forming convex and concave molds and flanging convex molds 17 required for processing products according to product surface design;

[0036] Described forming male and female mold comprises forming male die 15 and forming female die 16, and both comprise the profile feature that product molding needs, and can keep the part that needs flanging when product flanging work;

[0037] The flanging punch 17 includes profile features required for product molding and contour features required for flanging;

[0038] (2) Forming convex and concave molds and flanging convex mold 17 are used for blanking of castings before making;

[0039] (3) Compile the numerical control program for processing forming convex and concave dies and flanging punches 17, compile the numerical control program for product tri...

Abstract

The invention discloses a process method for a heat-insulating sample car sample, which comprises the following steps: designing a forming punch, a forming concave die, and a flanging punch according to the product profile, and preparing product trimming lines, product hole positions and product apertures Line program; stamping forming; draw product trimming line, product hole position line, product aperture line on the part; manual trimming; manual punching; manual trimming; manual wrapping; finally get the product. The adjusted process method of the invention ensures the product quality requirements. In the traditional technical scheme, it takes a lot of time and invests a lot of mold material costs to reduce the link of mold production and processing. It saves the technical preparation time, reduces the mold input cost, thereby reduces the cycle of heat insulation sample production, and improves the competitiveness of the enterprise in the market economy.

Description

technical field [0001] The invention relates to a processing technology for auto parts, in particular to a process method for a heat-insulating sample car sample. Background technique [0002] At present, the delivery period required by customers for car and car heat insulation samples is getting shorter and shorter. The period from the issuance of product demand orders to the delivery of samples is generally about 50 days. After removing the product testing and logistics transportation time, the time left for sample production is only about 40 days. Because it is a trial production of a prototype, it is determined that the demand for the product in the prototype stage is not large, generally 20 units. If you want to use the traditional formal mold stamping process to ensure the delivery of samples, then the manufacturing cost and cycle of the mold cannot meet the low-cost and short-cycle delivery requirements required by customers. Traditional stamping molds will spend a ...
