Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 and figure 2 As shown, the outer punching device for the inner wall of the hydraulic tappet shell of this solution includes a hydraulic tappet shell clamping device and a punching device.

[0032] The clamping device includes a bottom plate 7 fixedly connected to the stamping equipment, which is fixedly connected to the V-shaped base 6 through bolts and pins. The base 6 becomes a horizontal plane, and the V-shaped pressing block can slide horizontally. The V-shaped briquetting block 2 is connected with the clamping cylinder head 1, and under the driving action of the cylinder, the tappet workpiece 3 during stamping is clamped, and the tappet workpiece 3 is loaded and unloaded when the cylinder returns. The clamping and loosening of the tappet workpiece 3 is realized through the linear motion of the cylinder.

[0033] The punching device inc...

Abstract

The invention belongs to the technical field of cold forming, in particular relates to hydraulic tappet housing inner wall punching equipment in an inner hydraulic gas adjuster of an automobile engine and method. The punching equipment comprises a tappet housing clamping device and a punching device, wherein the hydraulic tappet housing clamping device comprises a V-shaped base fixedly connected with a base plate, and a V-shaped press block arranged on the same horizontal plane with the V-shaped base, and the V-shaped press block is connected with an air cylinder for punching a clamping workpiece; and the punching device comprises a punch head base plate mechanism fixedly connected with the base plate, a punch head mechanism arranged in a tappet housing and comprising a punch head which is accordant with the axial direction of the housing to provide a radial punch force, and a punch mechanism arranged in the tappet housing and comprising a punch which is perpendicular to the axial direction of the housing, to undertake the radial punch force of the punch head mechanism, so that the radial punch force is converted into a transverse punch force aiming at the inner wall of the tappet housing. According to the invention, the technical problem that the burrs remain on the hydraulic tappet housing after a hole is formed can be solved.

Description

technical field [0001] The invention belongs to the technical field of cold forming, and in particular relates to a punching device and method for a shell inner wall of a hydraulic tappet in a hydraulic clearance adjuster in an automobile engine. Background technique [0002] In the processing of hydraulic tappet shell holes, there are currently two processing techniques: shell outside drilling and shell outside punching. [0003] The external drilling of the shell has the following disadvantages: the external drilling takes a long time to process, and the burrs will turn inward after drilling, resulting in the need for deburring one by one in the subsequent process. Shell deburring is easy to miss processing and the burr inside the shell is not easy to remove. After heat treatment, the tiny burrs in the shell will become very brittle, which may cause the burrs to fall off after the parts are installed, seriously affecting the function of the product. [0004] The outer sh...
