Abstract

The invention relates to an edge trimmer for solving the technical problems that that handwork is difficult to cut a sheet material into a complex concave curve. A mainshaft of the edge trimmer is arranged inside a mainshaft seat by a bearing; the inside of a tool post seat of the mainshaft seat is provided with an eccentric wheel; the eccentric wheel is connected to the outer end of the mainshaft; a tool post rocking ram is arranged on the tool post seat through the bearing; the base part of the tool post rocking arm and the eccentric wheel are in sliding arrangement; the end part of the tool post rocking arm is provided with an upper blade; a lower transmission shaft is arranged inside a sliding shaft through the bearing, and the sliding shaft is arranged inside a linear bearing seat through a linear bearing, so that the sliding shaft can only do linear motion in the axial direction and cannot rotate; the inside of a steering gear seat at outer end of the sliding shaft is provided with a shaft end steering gear component and a blade steering gear component which are engaged with each other; the shaft end steering gear component is connected with the outer end of a lower transmission shaft; and the end part of the blade steering gear component is provided with a lower rotatory blade. The upper blade driven by the mainshaft cuts the lower rotatory blade driven by the lower transmission shaft to complete the cutting and side trimming of a workpiece.

Description

technical field [0001] The invention belongs to the field of cutting equipment, in particular to a trimming machine. Background technique [0002] In the prior art, industries such as clothing, tanning, shoemaking, rubber and plastic products, for the cutting process of complex curved sheets, mainly rely on manual cutting with scissors to remove waste edges. Some thicker sheets, such as shoe soles, etc., are time-consuming, labor-intensive, and labor-intensive when cutting concave curves, and the cutting effect is poor, often resulting in a high scrap rate. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the above-mentioned prior art, and provides a trimming machine. [0004] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: a trimming machine, including a frame, a main shaft is arranged on the upper part of the frame, a synchronous lower transmi...
