Abstract
The utility model provides a lower mould edge of a knife mold insert, includes the mold insert body, edge of a knife one side of mold insert body is close to edge of a knife one end department and is equipped with first tapering groove, and the edge of a knife opposite side is close to edge of a knife other end department and is equipped with second tapering groove. Due to the adoption of the structural design, the first taper groove and the second taper groove are arranged on the lower die cutting edge insert, and after the punching and shearing of the waste materials are completed, the small and light waste materials can be clamped in the first taper groove or the second taper groove and can only be discharged downwards, and can not be taken out of a die surface by a punch to damage the die, so that the normal production is ensured.
Description
Technical Field
The utility model relates to the technical field of stamping dies, in particular to a lower die knife edge insert.
Background
In the prior art, a stripper plate and a lower template press a product, an upper die moves downwards, a punch and a punching female die finish a punching process, and in the process of returning the upper die to the upper die, the punch easily brings small and light waste into the lower template, so that the normal production of the die is influenced. The common solution is to add thimbles on the punch, but the size of the punch cannot increase thimbles, and the aluminum material is too light and is easy to be brought into the die; or an air blowing device is added on the punch, but the punch is only 2.0mm thick, and the air blowing device cannot be realized.
Accordingly, the prior art is subject to improvements and enhancements.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model aims to provide the lower die knife edge insert which is simple in structure and can prevent a die from being damaged by the fact that a punch head is taken out of a die surface after waste punching and shearing are finished.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a lower mould edge of a knife mold insert, includes the mold insert body, edge of a knife one side of mold insert body is close to edge of a knife one end department and is equipped with first tapering groove, and edge of a knife opposite side is close to edge of a knife other end department and is equipped with second tapering groove.
Preferably, the first taper groove and the second taper groove are both two-stage taper grooves.
Preferably, the cross section of the two-stage taper groove is in a half-track shape.
Preferably, the two-stage taper groove comprises a first-stage taper groove with the taper of 5 degrees and a second-stage taper groove with the taper of 2.5 degrees.
Compared with the prior art, the utility model has the beneficial effects that:
due to the adoption of the structural design, the first taper groove and the second taper groove are formed in the lower die cutting edge insert, after the punching and shearing of the waste materials are completed, the small and light waste materials can be clamped in the first taper groove or the second taper groove and can only be discharged downwards, the punch can not be used for driving the die surface to damage the die, and the normal production is ensured.
Drawings
FIG. 1 is a top view of the present invention;
fig. 2 is an enlarged view of a portion I of fig. 1.
The reference numbers in the figures are respectively: (1) the insert comprises an insert body, (2) a knife edge, (3) a first taper groove and (4) a second taper groove.
Detailed Description
The utility model is described in further detail below with reference to the accompanying drawings:
referring to fig. 1 and 2, the lower die cutting edge insert of the present invention comprises an insert body 1, wherein a first taper groove 3 is arranged at one side of a cutting edge 2 of the insert body near one end of the cutting edge, and a second taper groove 4 is arranged at the other side of the cutting edge near the other end of the cutting edge; the first taper groove 3 and the second taper groove 4 are both two-stage taper grooves; the section of the two-stage taper groove is in a half runway shape; two-stage tapering groove includes that the tapering is 5 degrees first order tapering grooves 3 and tapering is 2.5 degrees second level tapering grooves 4, through foretell structural design, after the waste material is cut and is accomplished, little and light waste material can block in first tapering grooves 3 or second tapering grooves 4, can only discharge downwards, can not be taken out the die face by the drift and beat bad mould, guarantees normal production.
In conclusion, the utility model solves the defects in the prior art through the structural design and has the characteristics of simple structure, reasonable design, strong practicability and the like.
