Edge cutting machine for rubber ring

Abstract

The invention discloses an edge cutting machine for a rubber ring. The edge cutting machine comprises a rack, the rack is provided with an upper arm and a base, a lifting mechanism is arranged on the upper arm, the lower portion of the lifting mechanism is connected with an upper punching head component, and a mould is arranged at the position, below the upper punching head component, on the base. The upper punching head component is composed of a barrel shell, an inner ring cutter, an outer ring cutter and a raised type plug, a connector is arranged at the top of the barrel shell, an inner pipe and an outer pipe which are distributed concentrically are arranged on the lower portion of the barrel shell, a top raised head of the raised type plug is placed in the inner pipe of the barrel shell, and the outer ring cutter is arranged on the lower portion of the raised type plug in a sleeved mode. The inner ring cutter is arranged in the outer ring cutter, the top face of the inner ring cutter abuts against the bottom face of the raised type plug, and the top face of the outer ring cutter abuts against the bottom of the outer pipe of the barrel shell. An electric heating ring is arranged between the inner pipe and the outer pipe, and insulation layers are arranged on the inner side and the outer side of the electric heating ring. The edge cutting machine has the advantages that mounting is convenient, the inner ring cutter and the outer ring cutter are more stable in the edge cutting process, and edge cutting quality is high.

Description

[0001] technical field [0002] The invention relates to a rubber ring processing equipment, in particular to a rubber ring trimming machine. [0003] Background technique [0004] Rubber rings are widely used in various mechanical equipment to play the role of gasket, seal, buffer, etc. The market demand is very large. Therefore, how to improve the production efficiency of rubber rings is an urgent technical problem in this industry. Injection molding and flash removal are two important steps in the rubber ring production process. [0005] Existing rubber ring flash repair depends on trimming machine, the structure of trimming machine is to include frame, frame has upper arm and base, upper arm is provided with lifting mechanism, and the lower part of lifting mechanism is connected with upper punching head Assemblies, the position below the upper punching head assembly on the base is provided with a mould, wherein the bottom of the upper punching head assembly has an inne...
