Abstract
The invention relates to a punching die for producing a hard alloy saw-tooth tool bit, comprising a die body, an upper punch seat, a lower punch seat, an upper punch and a lower punch, wherein the upper punch and the lower punch are respectively installed on the upper punch seat and the lower punch seat, an upper fixing sheet and a lower fixing sheet are respectively arranged between the upper punch seat and the upper punch as well as between the lower punch seat and the lower punch; the upper punch is sleeved on the upper fixing sheet; the lower punch is sleeved on the lower fixing sheet; annular pad forks are also sleeved at two sides of the lower punch; the die body is placed on the upper end faces of the annular pad forks; a die cavity is formed by the upper end face of the lower punch and the die body; and the upper punch is correspondingly arranged above the die cavity. Because the annular pad forks, the upper fixing sheet and the lower fixing sheet are arranged, the punching die for producing the hard alloy saw-tooth tool bit has simple structure and is convenient for mounting and dismounting; when the punching die is produced, the damage to the lower punch, caused by stress concentrated on the lower punch, is avoided by means of the annular pad forks through stamping the upper punch and the lower punch in one step, and the stamping is stable, therefore, the production efficiency is greatly improved, the maintenance cost is saved, and the product quality is enhanced.
Description
Technical field
The present invention relates to a kind of diel, especially relate to a kind of diel of producing the carbide alloy saw-tooth tool bit, belong to machinery knives manufacturing technology field.
Background technology
The existing cutter head mould of producing the carbide alloy saw-tooth tool bit, it is to produce the carbide alloy saw-tooth tool bit with punching press about the low punch while on the forcing press, traditional use Mould operation instability, punching press bottom low punch is fixing unstable, influence the quality of product processing, and production efficiency is very low, easily causes the infringement of low punch, increases maintenance cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of punching press stable, simple in structure, the diel of the production carbide alloy saw-tooth tool bit of operation and convenient disassembly.
The present invention is achieved through the following technical solutions:
A kind of diel of producing the carbide alloy saw-tooth tool bit, comprise mold, it is characterized in that, it also comprises the upper punch headstock, low punch seat and installing respectively, on on the low punch seat, low punch, be respectively equipped with stator and following stator between described upper punch headstock and the upper punch and between low punch seat and the low punch, socket upper punch on last stator, socket low punch on the following stator, described low punch both sides also are socketed with annular fork, stick at described air ring and to place mold on the end face, described low punch upper surface and mold constitute die cavity, and described upper punch correspondence is arranged on the die cavity top.
According to above-mentioned a kind of diel of producing the carbide alloy saw-tooth tool bit, wherein, what described mold material adopted is Hardmetal materials.
The present invention is by being provided with annular fork and upper and lower stator, it is simple in structure, convenient disassembly, when producing, pass through once to go up the low punch punching press, avoided stress to concentrate on the damage of the low punch that causes on the low punch by annular fork, its punching press is stable, enhances productivity greatly, save maintenance cost, improved the quality of product.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of present embodiment.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
Embodiment:
Referring to Fig. 1, present embodiment is a kind of diel of producing the carbide alloy saw-tooth tool bit, comprise mold 5, upper punch headstock 1, low punch seat 10 and install respectively, the upper and lower drift on the low punch seat.Be respectively equipped with stator 3 and following stator 9, socket upper punch 4 on the last stator 3, socket low punch 7 on the following stator 10 between upper punch headstock 1 and the upper punch 2 and between low punch seat 10 and the low punch 7.
In the present embodiment, what described mold 1 material adopted is Hardmetal materials, and annular fork 8 also can adopt Hardmetal materials, increases robustness, avoids the infringement of low punch 7.
When present embodiment uses, upper and lower stator is installed on the upper and lower punch holder by screw, then at the mid portion of the upper and lower stator upper and lower drift of pegging graft respectively, and at the outer race T-Ring shape fork 8 of low punch 7.Last mold 5 at annular fork 8 upper ends Hardmetal materials, this mold 5 is a cemented carbide powder with the die cavity 6 interior raw materials of placing the making cutter head that low punch 7 upper surfaces form, again at mold 5 upper end socket upper punch 2, thereby be combined as a unitary mould, be placed on the forcing press compacting and can produce the carbide alloy saw-tooth tool bit.
The present invention has fully disperseed the stressed of low punch by plug-in mounting annular fork 8 is set, and has avoided the infringement of low punch 7, and it is simple in structure, convenient disassembly, by once going up the low punch punching press, operation is fast, conveniently when producing, enhance productivity greatly, saved cost.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
Claims (2)
