Technical Field

The invention relates to a cutter for punching a filter element.

Background

At present, a commonly used filter element punching cutter is cylindrical, waste materials generated by punching are left in a cutter body and cannot automatically fall off, equipment needs to be stopped when each hole is punched, the waste materials are taken out, and then a next product is processed, so that the improvement of production efficiency is limited. Based on the current situation, the inventor develops a filter element punching cutter which is more suitable for production requirements through diligent research and experiments.

Disclosure of Invention

Aiming at the defects of the prior art, the invention aims to design the cutter for punching the filter element, so that no flying floc is generated during punching, waste materials can automatically fall off from the cutter, and the continuous punching can be realized, thereby improving the working efficiency.

In order to achieve the purpose, the invention adopts the following technical scheme: a filter element punching cutter capable of automatically stripping materials comprises a cutter body and an elastic structure positioned in the cutter body; the cutter body is formed by connecting an upper cutter body and a lower cutter body which are concentric and have different diameters in a vertical manner, the diameter of the upper cutter body is smaller than that of the lower cutter body, and the upper cutter body is arranged on a machine tool; the inner cavity of the lower body of the cutter body is divided into an upper section and a lower section, wherein the upper section is a cylindrical cavity, and the lower section is a truncated cone-shaped cavity;

the elastic structure consists of a bolt, a spring and a nut, the bolt and the cutter body are concentrically arranged, the upper part of the bolt is inserted into the upper body of the cutter body and fixedly connected with the upper body of the cutter body, the lower part of the bolt extends into an inner cavity of the lower body of the cutter body, the spring is sleeved at the lower part of the bolt, the nut is sleeved at the bottom end of the bolt, and the spring is limited by the upper end surface of the lower body of the cutter body and the nut and has initial pretightening; the initial position of the nut is arranged at the upper part of the truncated cone-shaped cavity of the lower body of the cutter body; when punching, upward movement and pressure spring when nut bottom receives waste material thrust, after punching, the waste material is automatic to deviate from in the cutter body under the reaction force of spring.

As an implementation mode, the screw rod of the bolt is of a telescopic structure, the nut is screwed and fixed with the bolt, and when the bottom of the nut is pushed by the waste material, the screw rod contracts upwards to drive the nut to compress the spring.

In one embodiment, the nut can move up and down on the bolt, and when the bottom of the nut is pushed by the waste materials, the nut moves up and presses the spring.

The automatic stripping filter core punching cutter is simple and ingenious in structure, the elastic structure is additionally arranged in the cutter body, when the upper cutter body is fixed on a machine tool and the lower cutter body drills a filter core, waste materials do not fly off and enter the lower cutter body, the waste materials contact with a nut and upwards compress a spring, the waste materials are stripped from the cutter body under the reaction force of the spring, automatic stripping of the waste materials is achieved, continuous punching operation is achieved, and working efficiency is improved.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The automatic material-removing filter element punching cutter shown in fig. 1 comprises a cutter body 10 and an elastic structure positioned in the cutter body; the cutter body 10 is formed by connecting an upper cutter body 11 and a lower cutter body 12 which are concentric and have different diameters in an up-and-down mode, the diameter of the upper cutter body 11 is smaller than that of the lower cutter body 12, and the upper cutter body 11 is installed on a machine tool; the inner cavity of the cutter body lower body 12 is divided into an upper section and a lower section, wherein the upper section is a cylindrical cavity, and the lower section is a truncated cone-shaped cavity 121;

the elastic structure consists of a bolt 20, a spring 30 and a nut 40, wherein the bolt 20 and the cutter body are concentrically arranged, the upper part of the bolt 20 is inserted into the upper body 11 of the cutter body and fixedly connected with the upper body, the lower part of the bolt 20 extends into the inner cavity of the lower body 12 of the cutter body, the spring 30 is sleeved at the lower part of the bolt 20, the nut 40 is sleeved at the bottom end of the bolt 20, and the spring 30 is limited by the upper end surface of the lower body 12 of the cutter body and the nut 40 and has initial pretightening force; the initial position of the nut 40 is arranged at the upper part of the truncated cone-shaped cavity 121 of the lower body of the cutter body; when punching, the bottom of the nut 40 moves upwards and compresses the spring 30 when being pushed by the waste, and after the punching is finished, the waste automatically falls out of the cutter body under the reaction force of the spring 30.

In a preferred embodiment, the screw of the bolt 20 is of a telescopic structure, the nut 40 is screwed and fixed to the bolt 20, and when the bottom of the nut 40 is pushed by the waste material, the screw contracts upwards to drive the nut to compress the spring 30.

As another embodiment, the nut 40 can move up and down on the bolt 20, and when the bottom of the nut 40 is pushed by the waste material, the nut 40 moves up on the bolt and presses the spring.

The above embodiments are only for explaining the present invention, and those skilled in the art can make various changes or modifications to the embodiments without departing from the principle and spirit of the present invention, and all technical solutions obtained by using the modifications of equivalent technical means fall within the scope of the claims of the present invention.
