Description

Novel layer board nut cut off die

Technical Field

The invention belongs to the technical field of machinery, and particularly relates to a novel supporting plate nut trimming die.

Background

The main defects of the processed products are that the product burr is large and a secondary shearing band is caused by the fact that the punching force of a punch repeatedly acts on a die and a workpiece in the trimming processing process, the gap of the trimming die slightly changes, the original die gap is changed, the product often generates a large amount of burrs and the secondary shearing band due to the die gap problem, and the product burr is difficult to remove in the subsequent deburring process, so that the die gap needs to be adjusted again. Therefore, the processing efficiency of the product is seriously influenced, and the processing period of the product is prolonged due to continuous repair and disassembly of the die and the clamping die.

Disclosure of Invention

The invention aims to overcome the defects and provide a method for adjusting the clearance of a die in the trimming process. Improve product machining efficiency, quality, shorten product processing cycle's novel layer board nut cut off die.

The purpose of the invention and the main technical problem of solving the invention are realized by adopting the following technical scheme:

the invention discloses a novel supporting plate nut trimming die which is characterized in that a cutting die body is arranged on the supporting plate nut; the upper surface of the lower die is fixedly provided with a guide pillar A and a guide pillar B respectively, the lower end and the middle part of the guide pillar B are sleeved with a spring, the upper end of the guide pillar B is sleeved with a guide sleeve, a plurality of balls are arranged on the guide sleeve, and the guide pillar A is inserted into the upper die.

The upper die is fixedly provided with a positioning pin, and the middle part of the upper die is provided with buffer rubber.

The guide sleeve and the ball can move up and down and rotate outside the guide pillar B.

The upper die can move up and down outside the guide post A.

Compared with the prior art, the invention has obvious beneficial effects; the technical scheme shows that: a guide pillar A and a guide pillar B are fixedly installed on the lower die respectively, a spring is sleeved at the lower end and the middle of the guide pillar B, a guide sleeve is sleeved at the upper end of the guide pillar B, a plurality of balls are installed on the guide sleeve, and the guide pillar A is inserted into the upper die. When the guide sleeve and the ball on the lower die are subjected to downward force, the ball moves downwards along with the guide sleeve, and because the guide sleeve, the ball and the guide pillar B have gaps, when the gap between the upper die and the lower die is changed, the guide sleeve, the ball and the guide pillar B are subjected to transverse and longitudinal forces, and when the guide sleeve and the ball move downwards, the relative position of the guide sleeve and the ball is changed to adjust the gap between the upper die and the lower die; the burr of the product after cutting edge is reduced, the repeated trimming of the die due to the clearance problem is avoided, the trimming times of the die are reduced, the service life of the die is prolonged, and the processing efficiency and the quality of the product are improved.

Detailed Description

The details of the embodiments, structures, features and functions according to the present invention are described in the following detailed description and the preferred embodiments.

The invention discloses a novel supporting plate nut trimming die which is characterized in that a cutting die body is arranged on the supporting plate nut; the upper surface of the lower die 7 is fixedly provided with a guide pillar A3 and a guide pillar B8 respectively, the lower end and the middle part of the guide pillar B8 are sleeved with a spring 1, the upper end is sleeved with a guide sleeve 2, the guide sleeve 2 is provided with a plurality of balls 9, and the guide pillar A3 is inserted into the upper die 4.

Go up mould 4 fixed mounting and have locating pin 6, the middle part is provided with cushion rubber 4.

The guide sleeve 2 and the ball 9 can move up and down and rotate outside the guide post B8.

The upper die 4 can move up and down outside the guide post a 3.

When the guide sleeve 2 and the balls 9 on the lower die 7 are subjected to downward force during use, the balls 9 move downwards along with the guide sleeve 2, gaps exist among the guide sleeve 2, the balls 9 and the guide pillar B8, when the gap between the upper die 4 and the lower die 7 changes, the guide sleeve 2, the balls 9 and the guide pillar B8 are subjected to transverse and longitudinal forces, and when the guide sleeve 2 and the balls 9 move downwards, the relative positions of the guide sleeve 2 and the balls 9 change to adjust the gap between the upper die 4 and the lower die 7.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modification, equivalent change and modification made to the above embodiment according to the technical spirit of the present invention are within the scope of the present invention without departing from the technical spirit of the present invention.
