Cutting mechanism

Abstract

The invention discloses a cutting mechanism. The cutting mechanism comprises a box body mounted on the upper surface of a middle fixed plate; a cutter shaft is horizontally mounted in the box body; a plane bearing 1 is mounted at one end, towards a feed port, of the cutter shaft; the outer periphery of the plane bearing 1 is sleeved with a movable sleeve; guide columns and cutter frames are arranged on the outer end surface of the plane bearing 1; a plane bearing 2 and a combination cap are mounted at one end, toward a discharge port, of the cutter shaft; the outer periphery of the middle part of the cutter shaft is fixedly sleeved with a belt wheel; two connecting rods are inserted in the middle fixed plate; an upper fixed plate is fixedly mounted at the upper ends of the two connecting rods; a limiting screw rod is downwards mounted on the center line of the upper fixed plate; taper cutter feeding rods are respectively hung on two edges of the upper fixed plate; the two taper cutter feeding rods are downwards connected with two guide columns; each guide column is in transmission connection with one corresponding cutter frame; a bearing bracket is mounted at the lower ends of the two connecting rods; and a bearing 2 in the bearing bracket is in rolling contact with the outer peripheral surface of a cam. The device is standard in cutting surface and stable in product quality.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, is used for processing elastic straight pins, and relates to a material cutting mechanism. Background technique [0002] The existing elastic cylindrical pin products are widely used, and in various locks and stainless steel furniture connectors, the amount used reaches one tenth of that of screws and nuts. However, in the production of elastic cylindrical pins in the past, it is difficult to cut the long cylindrical raw material with slits directly, and the incision is easily deformed, which makes the cutting surface of the product non-standard and affects the overall processing quality. Contents of the invention [0003] The invention provides a material cutting mechanism, which solves the problems in the prior art that it is difficult to directly cut long cylindrical raw materials with slits, the incision is easily deformed, and the overall quality of the finished product is aff...
