Abstract

A punching device preventing an automobile sealing strip with a skeleton from machining deformation comprises a female die 7, a pressure plate 5 and a cutter 6, and is characterized in that a groove 9 for placing the sealing strips and a guide mechanism 8 for guiding the cutter 6 to finish the punching operation are arranged on the female die 7; the guide mechanism 8 is intersected with the groove 9 to form a guiding included angle Gamma; the cutter 6 is provided with a horizontal cutting edge 12 and a vertical cutting edge 10; the moving direction of the horizontal cutting edge 12 and the moving direction of the cutter 6 form a cutting edge included angle Beta 1; one end, far from the pressure plate 5, of the horizontal cutting edge 12 inclines towards the punching advance direction of the cutter 6; the cutting edge included angle Beta 1 is smaller than the guiding included angle Gamma; in punching, the sealing strips are cut step by step by the horizontal cutting edge 12 at first, then are cut by the vertical cutting edge 10, so that the impulsive force of the cutter 6 on the sealing strips is reduced, and the deformation of the sealing strips is further reduced, the incision surfaces of the sealing strips are smooth, and the skeleton deformation is avooided.

Description

technical field

[0001] The invention relates to a punching device, in particular to a punching device with a skeleton automobile sealing strip, which belongs to the technical field of cutting and processing of automobile parts. Background technique

[0002] The sealing strip is one of the important parts for the sealing of automobile doors and windows, and it is also one of the important decorative parts on the automobile. In the actual production of the sealing strip, after the sealing strip is formed, it is usually necessary to machine a cutout at its end to meet the requirements of assembly and connection when the sealing strip is used. like figure 1 The sealing strip shown is a commonly used sealing strip for car window sealing at present. According to the requirements of assembly and connection, a slit needs to be machined at one end of the sealing strip, and the incision is required to have a longitudinal section 1 and a transverse section 2. Since a part of the long...
