Abstract
The utility model provides a cutting edge embedding structure of a trimming die, wherein the middle part of the trimming die is a hollow groove to be processed, screw holes are arranged at two sides of the hollow groove, the edge of the hollow groove is a cutting edge, the cutting edge is an embedding cutting edge, and the trimming die is the same as the cutting edge in material; the trimming die and the cutting edge are made of 27CrNiMo materials. The beneficial effects are as follows: the trimming die base material is made of 27CrNiMo, so that the cost is greatly reduced, the cutting edge is embedded at the cutting edge of the trimming die, the cutting edge is not easy to wear, the service life of the die is prolonged, and the cost of the die is reduced; the residual flash of the forging is reduced, the quality of the forging is improved, the process of cleaning and grinding is reduced, and the production efficiency is improved.
Description
Technical Field
The utility model relates to a mould processing field especially indicates a cut off die cutting edge structure.
Background
The main colliery hydraulic support of producing of my company, this product is great in batches, and current trimming die performance is lower, and trimming die blade department easily wears out, and the incorruptibility is low, leads to the remaining overlap increase after the forging is cut edge, influences the forging quality, and need often change the trimming die after the blade wearing and tearing, influences the product progress, increase cost.
The trimming die needs to be made of 5CrNiMo, the cost of die materials is high, the hardness of a cutting edge is inconsistent with that of a base material when the same material is quenched, the operation is inconvenient, the heat treatment of the trimming die is difficult, and the result is not ideal. The hardness of the cutting edge is too high, so that the brittleness is increased, the cutting edge is easy to break during trimming, and potential safety hazards exist
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a trimming die cutting edge structure.
The technical scheme of the utility model is realized like this:
an edge cutting die insert pocket structure comprising: the edge cutting die comprises an edge cutting die, wherein the middle part of the edge cutting die is a hollow groove to be processed, screw holes are formed in two sides of the hollow groove, the edge of the hollow groove is a cutting edge, the cutting edge is an insert edge, and the edge cutting die is made of the same material as the cutting edge.
Furthermore, 27CrNiMo materials are selected for the trimming die and the cutting edge.
Further, the cutting edge is a No. 45 steel quenching and tempering cutting edge.
The beneficial effects are that: the trimming die base material is made of 27CrNiMo, so that the cost is greatly reduced, the cutting edge is embedded at the cutting edge of the trimming die, the cutting edge is not easy to wear, the service life of the die is prolonged, and the cost of the die is reduced; the residual flash of the forging is reduced, the quality of the forging is improved, the process of cleaning and grinding is reduced, and the production efficiency is improved.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a cross-sectional view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1 to 2, an insert edge structure of a trimming die includes: trimming die 1, trimming die 1 middle part is for waiting the hollow groove 2 of processing, be screw 4 in the both sides of hollow groove 2, the edge of hollow groove 2 is blade 3, blade 3 is for inlaying the blade, trimming die 1 is the same with the material of blade 3, 27CrNiMo material can all be chooseed for use with blade 3 to trimming die 1, blade 3 can also adopt 45# steel quenching and tempering to inlay the blade, can reduce the remaining overlap of forging, improve the forging quality, reduce the clear process of grinding, improve production efficiency.
The cutting edge 3 of the trimming die 1 is embedded with the cutting edge, so that the cutting edge 3 is not easy to wear, the service life of the die is prolonged, and the cost of the die is reduced.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
