Problems solved by technology

[0002] The daily processing number of existing cold extrusion machine tools can reach 12,000. Due to the limitations of existing processing and quenching processes, the life of the matching cold extrusion tools is very short under such high-intensity processing conditions. Some knives need to be changed almost every 2 days, and the existing knives are disposable and cannot be reused, which not only increases the processing cost, but also is not conducive to the improvement of production efficiency

Embodiment 1

[0009] Embodiment 1, with reference to appended Figure 1-2 .

[0010] An extruding tool, including four identical, uniformly radially distributed relative to the workpiece 1 to be processed, flap-type opening and closing tool units 2, each of the tool units 2 includes a blade portion 21, and the The blade 21 includes a first blade 211 above the blade and a second blade 212 below the blade. The first blade 211 and the second blade 212 are symmetrical about the center of the blade 21 . The tool is made of high-quality hard alloy material with high hardness. After rough machining, it is quenched and then precision ground. Because it is processed into a double-edged part, the service life of the tool has been improved qualitatively, because there is no batch problem. Therefore, the replacement of the tool has almost no impact on production, and the problem of complex tool replacement has been further improved.

Embodiment 2

[0011] Embodiment 2, with reference to appended Figure 1-3 .

[0012] Others are similar to Embodiment 1, except that a part of the first blade portion 211 and the second blade portion 212 is provided with a texture 213 by electric discharge machining. It can increase the friction between the workpiece and the tool, and improve the added value and use effect of the product.

Abstract

The invention relates to an extrusion mouth cutting tool. The extrusion mouth cutting tool comprises multiple cutting tool individual bodies which are the same, uniformly and radially distributed according to a to-be-processed workpiece and opened and closed in a disc type, wherein each cutting tool individual body comprises a blade part, the blade part comprises a first blade part arranged above the blade part and a second blade part arranged below the blade part, and the first blade part and the second blade part are in central symmetry relative to the central point of the blade part; and each cutting tool individual body adopts a disc type structure and is easy to disassemble, the blade part of each cutting tool individual body can be repaired and processed after each cutting tool individual body is disassembled, and thus the aim of secondary utilization is realized.

Description

technical field [0001] The invention relates to the technical field of processing equipment, in particular to an extrusion tool for a cold extrusion machine tool. Background technique [0002] The daily processing number of existing cold extrusion machine tools can reach 12,000. Due to the limitations of existing processing and quenching processes, the life of the matching cold extrusion tools is very short under such high-intensity processing conditions. Some knives need to be changed almost every 2 days, and the existing knives are disposable and cannot be reused, which not only increases the processing cost, but also is not conducive to the improvement of production efficiency. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a reusable extrusion tool with long service life, which has the function of self-locating the center of a circle in multiple directions through external force. ...
