A punching die for fixing a cover plate with fine-toothed needle cloth

Abstract

This utility model discloses a punching die for fixing a fine-toothed needle cloth with a cover plate, including a fixed die assembly, a first punching assembly, and a second punching assembly. The first punching assembly and the second punching assembly are located above the fixed die assembly. The first punching assembly is used to pre-punch the needle cloth, and the second punching assembly is used to punch the needle cloth. By punching with the first and second punching assemblies, the needle cloth products are arranged in an alternating pattern using a single die. Furthermore, the pre-punching by the first punching assembly prevents damage to the tooth profile caused by improper cutting of the needle cloth.

Description

Technical Field

[0001] This utility model belongs to the field of needle cloth production technology, specifically relating to a punching die for fixing a cover plate of fine-toothed needle cloth. Background Technology

[0002] The fixed cover plate with dense-toothed carding cloth is a key carding element in a carding machine. It is mainly used for pre-carding and supplementary carding, and improves fiber separation and carding effect through its dense tooth structure.

[0003] In existing technologies, because the toothed needle cloth with a fixed cover plate has deep teeth and high tooth density in order to allow sufficient air to pass through, the teeth are damaged when the needle cloth is cut due to the inability to avoid misalignment. If two sets of molds are used for punching, the sorting and arrangement of the needle cloth becomes too difficult and inefficient. Utility Model Content

[0004] The purpose of this invention is to provide a punching die for fixing the cover plate and the fine-toothed needle cloth, which solves the problem in the prior art that the tooth shape is damaged when cutting the needle cloth because the die cannot avoid the misalignment.

[0005] Therefore, this utility model provides a punching die for fixing a cover plate with fine-toothed needle cloth, including a fixed die assembly, a first punching assembly and a second punching assembly, the first punching assembly and the second punching assembly being above the fixed die assembly, the first punching assembly being used to pre-punch the needle cloth, and the second punching assembly being used to punch the needle cloth.

[0006] Preferably, the first punching assembly includes a first moving die base, a first pad, and a first punch fixing plate that are fixedly connected in sequence, and the first punch is fixedly installed on the bottom of the first punch fixing plate.

[0007] Preferably, the first punch is provided with stamping blocks at both ends.

[0008] Preferably, the stamping block is inclined.

[0009] Preferably, the inclination direction of the stamping block is the same as the direction of the tooth tip of the needle cloth.

[0010] Preferably, the second punching assembly includes a second moving die base, a second pad, and a second punch fixing plate, which are fixedly connected from top to bottom, and the second punch is fixedly installed at the bottom of the second punch fixing plate.

[0011] Preferably, the second punch is a forming punch.

[0012] Preferably, the fixed mold assembly includes a stripper plate, a die, a backing plate, and a fixed mold base that are fixedly connected in sequence.

[0013] Preferably, the fixed mold assembly includes a slide rod that passes through the stripper plate, the die cavity, and the pad, and the slide rod is fixedly connected to the fixed mold base.

[0014] Preferably, the first punching assembly and the second punching assembly are slidably connected to the slide bar.

[0015] Beneficial effects:

[0016] This utility model provides a punching die for fixing a cover plate with closely spaced needle cloth. The die is punched by a first punching component and a second punching component. The needle cloth products are arranged in an alternating manner through a die. Furthermore, the pre-punching of the first punching component avoids damage to the tooth shape when cutting the needle cloth due to the inability to avoid the needle. Attached Figure Description

Detailed Implementation

[0026] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0027] Example 1:

[0028] Provided such as Figure 1 The die shown is a punching die for fixing a cover plate with fine-toothed needle cloth, including a fixed die assembly 1, a first punching assembly 2 and a second punching assembly 3. The first punching assembly 2 and the second punching assembly 3 are above the fixed die assembly 1.
