Punching die for car doorframe posts

Abstract

Disclosed is a punching die for car doorframe posts. A vertical static die fixing plate and a moving die sliding seat are disposed on a lower die plate. A vertical static die is embedded in the middle of the static die fixing plate. A groove is vertically arranged on the moving die sliding seat. A moving die fixing seat which is capable of moving upwards and downwards along the groove is inserted in the groove. Vertical openings are reserved at a position which the moving die fixing seat and the static die are matched with each other. An upper moving die and a lower moving die are disposed in each opening and an upper die driving block is fixed above the upper moving die. The bottom of moving die fixing seat is provided with an elastic member which enables the moving die fixing seat to ascend. An elastic member is also disposed between the upper moving die and the lower moving die, and the elastic member drives the upper moving die and the lower moving die to separate. The punching die for car doorframe posts is high in production efficiency, and low in manufacture cost and production cost.

Description

technical field [0001] The invention relates to a mold, in particular to a punching mold. Background technique [0002] At present, the domestic processing of vehicle door frame pillars usually adopts the method of sawing. As disclosed in the Chinese patent CN201446558U, "a cutting machine for a fixed frame of an automobile door sealing strip", this cutting production method is not only inefficient, but also has a low production capacity. It takes 30 to 60 seconds to cut a piece of this type of product. and the cost is high, the cost of manufacturing a sawing machine needs about 150,000 yuan, and the cost of a saw blade is about 1,000 yuan. The life of the saw blade is calculated on the basis of 2000PCS, the cost of cutting a column is 0.5 yuan, and the output is calculated on the basis of 1 million pieces in 5 years, the cost of the saw blade is 500,000 yuan, so the cost is relatively high, which is not conducive to production. [0003] If the column is cut by punching, m...

Problems solved by technology

As disclosed in the Chinese patent CN201446558U, "a cutting machine for a fixed frame of an automobile door sealing strip", this cutting production method is not only inefficient, but also has a low production capacity. It takes 30 to 60 seconds to cut a piece of this type of product. ; And the cost is high, the cost of manufacturing a sawing machine needs about 150,000 yuan, and the cost of a saw blade is about 1,000 yuan

The life of the saw blade is calculated on the basis of 2000PCS, the cost of cutting a column is 0.5 yuan, and the output is calculated on the basis of 1 million pieces in 5 years, the cost of the saw blade is 500,000 yuan, so the cost is relatively high, which is not conducive to production

[0003] If the column is cut by punching, many difficulties need to be overcome. First of all, it is very difficult to insert the product into the punching mold cavity, and the insertion gap needs to be increased. Moreover, the product is cut by shearing. If the gap is too large, the product After punching, there will be broken burrs, and the deformation of the product will increase

Therefore in the prior art, punching is not adopted to cut off the mold of the vehicle door frame column.
