Semiautomatic trimming machine for rubber parts

Abstract

The invention discloses a semiautomatic trimming machine for rubber parts. A workpiece rotary driving device, a radial cutting mechanism and an end-direction cutting mechanism are disposed on a base. The radial cutting mechanism comprises a radial cutter holder and a radial cutter slidably arranged on the radial cutter holder, a driving pressure spring abutted against the tail end of the radial cutter is arranged on the radial cutter holder, and the radial cutter is connected with a radial feed control handle through a clutch device. The end-direction cutting mechanism comprises an end-direction cutter holder, an end-direction feed control handle, a slider and an end-direction cutter, wherein the end-direction cutter is rotatably arranged on the head of the slider which is slidably arranged on the end-direction cutter holder. A torsion spring driving the end-direction cutter to rotate is arranged on the slider, and the middle of the end-direction feed control handle is hinged to the end-direction cutter holder and hinged to the tail of the slider through a connecting rod. The radial cutter and the end-direction cutter are both fixed in floating manners, trimming is thorough and effective, product damage can be avoided, and manufacturing cost is low.

Description

technical field [0001] The invention relates to a post-processing device for rubber parts, in particular to a trimming device for removing flash edges of rubber parts. Background technique [0002] In the production process of rubber products, in order to prevent the lack of glue, the rubber filled in the mold cavity will maintain a certain excess. At the stage of molding vulcanization, the rubber will quickly fill the mold cavity, and the excess rubber will pass through the mold parting surface or The joint with the metal insert overflows to form flash. Once the flash is formed, it must be trimmed to get a good product, so that the appearance of the product is neat and beautiful. [0003] The current trimming methods are mainly as follows: [0004] 1. Manual edge trimming, that is, the operator holds a knife and gradually removes the flash along the outer edge of the product. This type of method is time-consuming, labor-intensive and inefficient, and it is easy to leave t...

Problems solved by technology

[0007] The purpose of the present invention is to solve the problems of high trimming cost, incomplete trimming, and easy damage to products existing in the existing rubber trimming method, and to provide a rubber rubber with a rotary body structure and at least one end with a metal end cap. A semi-automatic trimming device for trimming parts, which has a good trimming effect, will not cause damage to the product, and is low in cost
