Description
Technical field
The present invention relates to powder compacting equipment technology fields, and in particular to a kind of punch device.
Background technique
When preparing the materials such as cermet, hard alloy, powder metallurgy process is industrially generallyd use, is mainly produced
Process includes compounding, mixing, sieving, molding, sintering and post-processing etc..Powder compacting is that operability is most strong in CEMENTED CARBIDE PRODUCTION
Process, be guarantee alloy blank precision, the critical process of apparent mass and alloy internal soundness.Hard alloy strip product
Powder compacting is suppressed usually using full-automatic mechanical press, and the formed punch connection structure of existing strip product is usually strip punching
Head is directly welded in drift mounting seat, and such formed punch connection structure usually can inevitably generate welding deformation, formed punch
Verticality and the depth of parallelism are unable to get guarantee；The liquidate institutional framework of head material of high-temperature soldering itself can also have an impact, and reduce
The service life of formed punch.Meanwhile when formed punch damage needs replacing, need together to replace formed punch and drift mounting seat,
Cause waste.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcomings of the prior art, provides that a kind of structure is simple, uses
Service life is long, can be individually replaced formed punch, save material, reducing production cost, conducive to guaranteeing strip formed punch verticality and the depth of parallelism
Punch device.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of punch device, including drift mounting seat and strip formed punch, the drift mounting seat are equipped with positioning runner, the strip
The bottom end of formed punch is equipped with sliding positioning region, and the sliding positioning region is slidedly arranged in the positioning runner, in the drift mounting seat
More than two tapped through holes being connected to positioning runner are additionally provided with, is fitted in each tapped through hole and is fixed the sliding
The screw of positioning region.
Above-mentioned punch device, it is preferred that the positioning runner is dovetail groove.
Above-mentioned punch device, it is preferred that the bottom surface of the dovetail groove is plane, and two sides of the dovetail groove have
At least one section with the vertical plane of plane perpendicular, the section of the sliding positioning region is identical as the section of dovetail groove, and the sliding
It is clearance fit between positioning region and the positioning runner.
Above-mentioned punch device, it is preferred that more than two tapped through holes are located at the same side of positioning runner and slide along positioning
The length direction interval of slot is arranged.
Compared with the prior art, the advantages of the present invention are as follows: punch device of the present invention is not needed using in the prior art
Mode is welded and fixed, avoids welding deformation, better assures that the verticality and the depth of parallelism of strip formed punch；It avoids because of high temperature
The damage to strip formed punch material structure is welded, the service life of strip formed punch is extended.In addition, when the damage of strip formed punch needs replacing
When, without replacing strip formed punch together with drift mounting seat, strip formed punch is only needed to change, to save material, is reduced
Production cost.Because without welding, strip punch head surface will not generate oxidation stain, increase the aesthetic appearance of mold.
Detailed description of the invention

Fig. 2 is the side structure schematic view of punch device of the present invention.
Fig. 3 is enlarged structure schematic diagram at A in Fig. 2.
Marginal data:
1, drift mounting seat；11, positioning runner；12, tapped through hole；2, strip formed punch；21, positioning region is slided；3, screw.
Specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, punch device of the present invention, including drift mounting seat 1 and strip formed punch 2, drift mounting seat 1
Equipped with positioning runner 11, the bottom end of strip formed punch 2 is equipped with sliding positioning region 21, and sliding positioning region 21 is slidedly arranged on positioning runner 11
In, it is additionally provided with two tapped through holes being connected to positioning runner 11 12 in drift mounting seat 1, is coupled in each tapped through hole 12
There is the screw 3 for being fixed sliding positioning region 21.It slides the cooperation of positioning region 21 by it and is slidedly arranged on to be formed in positioning runner 11 and determine
Position, then using screw 3 be fixed sliding positioning region 21, can by strip formed punch 2 it is solid and reliable be fixed on drift mounting seat 1
On.The punch device does not need that mode is welded and fixed using in the prior art, avoids welding deformation, better assures that length
The verticality and the depth of parallelism of formed punch 2；The damage because of high-temperature soldering to 2 material structure of strip formed punch is avoided, strip is extended
The service life of formed punch 2.In addition, when the damage of strip formed punch 2 needs replacing, without by strip formed punch 2 and drift mounting seat 1 together more
It changes, only needs to change strip formed punch 2, to save material, reduce production cost.Because without welding, 2 surface of strip formed punch is not
Oxidation stain can be generated, the aesthetic appearance of mold is increased.
In the present embodiment, positioning runner 11 is dovetail groove.As shown in figure 3, the bottom surface of the dovetail groove is plane, dovetail groove
Two sides have the vertical plane of at least one section with plane perpendicular.The section for sliding positioning region 21 is identical as the section of dovetail groove,
It and is clearance fit between sliding positioning region 21 and positioning runner 11.The positioning runner 11 of this kind of structure type and sliding positioning region
21 cooperations can guarantee the fixed solid and reliable property of strip formed punch 2.
In the present embodiment, two tapped through holes 12 are located at the same side of positioning runner 11 and along the length sides of positioning runner 11
It is arranged to interval.This kind of arrangement can effectively be fixed strip formed punch 2, and convenient for dismounting to screw 3.At other
In embodiment, it can also be used three and strip formed punch 2 fastened with screwing 3.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example.To those of ordinary skill in the art, obtained improvement and change in the case where not departing from the technology of the present invention concept thereof
It changes and also should be regarded as protection scope of the present invention.
