Bur removing device of plastic sleeve

Abstract

Disclosed in the invention is a bur removing device of a plastic sleeve. The device comprises a rotation mechanism, a punching mechanism and a bur removing mechanism. The rotation mechanism includes a fixed plate and a rotation plate; the fixed plate is arranged at the opposite side, relative to the punching mechanism, of the rotation plate; and fixed through holes for fixing a plastic sleeve are distributed in the rotation plate at the peripheral direction. The punching mechanism consists of an annular pedestal, punching rods, a punching drive unit, and connecting posts; the punching rods with the external diameters increasing in an ascending order are distributed on the annular pedestal successively along the periphery; the positive projection of the punching rods on the rotation plate are superposed with the axis of the plastic sleeve; and the punching rods are fixedly connected to the output terminal of the punching drive unit. The bur removing mechanism includes an independent drive unit and a bur removing rod fixedly connected to the output terminal of the independent drive unit, wherein the external diameter of the bur removing rod is identical with the external diameter of the adjacent punching rod. The device has the following advantages: burs formed at the inner wall of the plastic sleeve of the wiring terminal can be removed; the production efficiency and the yield are improved; the output amount and the output value are increased; and unnecessary wasting is reduced.

Description

technical field [0001] The invention relates to a punching device in production equipment, in particular to a device for punching and deburring plastic sleeves of terminal blocks. Background technique [0002] The traditional device for stamping the plastic sleeve on the terminal includes a punching mechanism and a rotating mechanism for placing the plastic sleeve. The rotating mechanism is distributed with fixed bases for fixing the plastic sleeve. The punching mechanism includes a ring base and a circumferential distribution. The stamping rods arranged clockwise on the annular base and arranged clockwise in order of thickness from small to large, the stamping rods are aligned with the axis of the plastic sleeve. [0003] Since the stamping process adopts the method of cold stamping, the inner wall of the plastic sleeve after stamping will have some burrs that are inevitably generated during the stamping process, which makes the inner wall of the plastic sleeve uneven and s...

Problems solved by technology

[0003] Since the stamping process adopts the method of cold stamping, the inner wall of the plastic sleeve after stamping will have some burrs that are inevitably generated during the stamping process, which makes the inner wall of the plastic sleeve uneven and smooth, so that in the next process plastic There are many unqualified products in the assembly of sleeves and terminals. Unqualified plastic sleeves with burrs cannot be sleeved on the outside of the terminals, resulting in low production efficiency, low pass rate, low factory output, and low factory value, resulting in unnecessary waste
