Abstract

The utility model belongs to cutter processing equipment field specifically is a mould is made to chopper edge of a knife. A mould is made to chopper edge of a knife, includes edge of a knife mould body, edge of a knife groove has been seted up on the edge of a knife mould body, edge of a knife groove is less than in its degree of depth of waiting to process the edge of a knife and waiting to cut the opposite side of thing contact in its degree of depth of waiting to process the edge of a knife and waiting to cut the thing contact side. The utility model provides the high manufacturing efficiency of the chopper edge of a knife, and the edge of a knife shape that obtains rule, excellent in use effect.

Description

A kind of chopper edge of a knife mfg. moulding die
Technical field
The utility model relates to tooling equipment field, particularly relates to a kind of chopper edge of a knife mfg. moulding die.
Background technology
At present, the manufacture method of chopper is roughly divided into two kinds: one is that the edge of a knife, knife plate, handle of a knife and the knife back are one-body molded by machine punching press cutter, and chopper blade obtained is like this of uniform thickness, and uses poor effect; Another kind is directly by manually forging shaping by the edge of a knife, knife plate, handle of a knife, the method needs to consume a large amount of time manpowers, efficiency low and the chopper edge of a knife obtained, knife plate, handle of a knife out-of-shape, be unfavorable for welding, and obtained chopper easily produces breach, crackle.The patent No. be CN203460192U patent discloses a kind of chopper, this chopper light structure, but the knife back, the edge of a knife and knife plate are one-body molded, require great effort during use, and easily there is disconnected steel phenomenon in the edge of a knife, and service life is short.
Utility model content
In order to overcome existing technical problem, the utility model proposes that a kind of to manufacture efficiency high, be shaped rule, the chopper edge of a knife mfg. moulding die that result of use is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of chopper edge of a knife mfg. moulding die, comprises edge of a knife die ontology; Described edge of a knife die ontology offers edge of a knife groove; Described edge of a knife groove, in the degree of depth of its edge of a knife to be processed with thing contact side to be cut, is less than the degree of depth of the opposite side contacted with thing to be cut at its edge of a knife to be processed.
The utility model adopts and has the edge of a knife Making mold edge of a knife of edge of a knife groove, and manually makes phase specific efficiency and is improved, and the rule and the edge of a knife of gained is shaped, be convenient to welding, not easily crack and breach, result of use is good.
Further, described edge of a knife groove comprises hook and gets portion and portion to be cut.
Further, portion to be cut described in is linearly straight portion; Described hook is got one end, portion and is linked into an integrated entity with portion to be cut, and the other end becomes angle to stretch out from portion to be cut rightabout.
Further, the central axis direction that central axis direction and the described hook in portion to be cut described in get portion is mutually vertical.
Further, described hook gets portion and portion described to be cut connects into L shape.
Further, described edge of a knife groove gets the rectangular shape in portion and junction, portion described to be cut at its edge of a knife to be processed and thing contact side to be cut, described hook; The opposite side contacted with thing to be cut at its edge of a knife to be processed, described hook get portion and junction, portion described to be cut in leading radiussed.
Further, described edge of a knife groove end extends to the side of described edge of a knife die ontology.
Further, described edge of a knife mould body bottom portion has the fixed part fixing with forging machine.
The beneficial effects of the utility model are, use chopper edge of a knife mfg. moulding die, improve the manufacture efficiency of the chopper edge of a knife, and the edge of a knife regular shape obtained, result of use is good.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model chopper edge of a knife mfg. moulding die;
Wherein: 1, edge of a knife die ontology, 2, edge of a knife groove, 3, fixed part.
Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of chopper edge of a knife mfg. moulding die, comprises edge of a knife die ontology 1; Described edge of a knife die ontology 1 offers edge of a knife groove 2.Wherein, edge of a knife groove 2, in the degree of depth of its edge of a knife to be processed with thing contact side to be cut, is less than the degree of depth of the opposite side contacted with thing to be cut at its edge of a knife to be processed.The thickness that this structure makes the edge of a knife manufacturing gained contact side with thing to be cut is less than the edge of a knife is connected side thickness with knife plate, the knife back, is convenient to the polishing of edge of a knife blade, is convenient to the edge of a knife and welds with knife plate, the knife back.
In addition, edge of a knife groove 2 comprises hook and gets portion and portion to be cut.Portion to be cut is linearly straight portion, for felling; Hook is got one end, portion and portion to be cut and is linked into an integrated entity, and the other end becomes angle to stretch out from portion to be cut rightabout, for will thing band be cut to hewer, be convenient to cut down.The central axis direction in portion to be cut makes portion to be cut be approximated to 90 degree with the angle hooking portion of getting with the central axis direction hooking portion of getting is mutually vertical, if angle is greater than 90 degree too much, is unfavorable for that thing to be cut hooks and gets; Angle is less than 90 degree too much, is unfavorable for that thing to be cut is cut down.Hook is got portion and is connected into L shape with portion to be cut, and hook portion of getting at its edge of a knife to be processed and the rectangular shape of thing contact side to be cut, the opposite side contacted with thing to be cut at its edge of a knife to be processed is rounding horn shape, is convenient to welding.
In addition, described edge of a knife groove 2 end can and the side of described edge of a knife die ontology 1 between there is difference in height, namely edge of a knife groove 2 does not open the side to edge of a knife die ontology 1, like this after having manufactured, the edge of a knife take out difficulty.And the side that described edge of a knife groove 2 end extends to described edge of a knife die ontology 1 is set, be convenient to the edge of a knife manufactured to take out.Edge of a knife groove is L-shaped, and make the edge of a knife manufacturing gained be L shape, the edge of a knife is installed in inverted L-shaped when mounted, and chopper is better used.
In addition, have the fixed part 2 fixing with forging machine bottom edge of a knife die ontology 1, fixed part 2 is a part for edge of a knife die ontology 1.First fixed by fixed part 3 during operation, be then placed in by the edge of a knife and forged by forging machine shaping in edge of a knife groove, after completing, the edge of a knife takes off by direct fixture, simple to operate, and the edge of a knife regular shape obtained.
The utility model improves the manufacture efficiency of the chopper edge of a knife, and the edge of a knife regular shape obtained, result of use is good.
