Abstract
A hard alloy round bar pressing die comprises a die body, an upper punch, a base wad and a fastening piece. The fastening piece comprises a die sleeve and a protective sleeve which is wrapped on the outer layer of the die sleeve, the die body is placed in the middle of the die sleeve, and the upper portion and the lower portion of the die body are limited through the upper punch and the base wad. Meanwhile, the die body is divided into an upper die body and a lower die body, and the upper die body and the lower die body are connected through threaded fastening pieces and connecting rods. The hard alloy round bar pressing die is simple in technology, convenient to machine, easy to assemble and convenient to use, breakage of side plates is reduced, and the service life of the die is prolonged.
Description
Technical field
The utility model relates to carbide alloy and makes the field, is specially a kind of carbide alloy pole pressing die of preparing the carbide alloy pole and improving its availability and detachability of can be used for.
Background technology
At present, the production strip carbide alloy that tradition is used (is mainly the cross section and is rule body, as pole, long straight square-section rod etc.) in the mould, usually the clamping plate that all comprise both sides, two clamping plate middle upper punch and heelpiece and the side plate that is arranged on the clamping plate two ends are set, and die body is one-shot forming, be installed in, between the heelpiece, and by fixture both sides and clamping plate are fixed at two ends, under this structure, the mould connected mode is comparatively complicated, and because the die body of one-time formed mould can not split, mold weight is big like this, and can't realize artificial lifting and turning operation in the pressing operation, dismantle very inconvenient, in addition, the operation in the process of compacting strip carbide alloy of this structure is also comparatively complicated, also easy mold damage.
The utility model content
The technical problem that the utility model solved is to provide a kind of carbide alloy pole pressing die, to solve the shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
Carbide alloy pole pressing die, comprise die body, upper punch, heelpiece and securing member, wherein, securing member comprises die sleeve and is wrapped in the outer field sheath of die sleeve, and die body is positioned in the middle of the described die sleeve, and it is spacing by upper punch and heelpiece in the upper and lower part, simultaneously, described die body is divided into upper die body and lower mold body, the centre connects by threaded fastener and connecting rod, the structure that this die body is divided into two, one of the dismounting upper punch that can pass through or heelpiece just can split out die body, can effectively reduce working strength.
In the utility model, adopt interference fit between described upper punch, die body and heelpiece and the die sleeve, its use level is 0.02mm～0.04m.
In the utility model, described die sleeve adopts tension to press the ferrous materials of superior performance to make, and preferably adopts 40 chromium steel or 9Mo2V alloy tool steel.
Beneficial effect: the utility model is transformed on original alloy bar pressing mold is signed an undertaking structure; by double-decker die body is protected; the stress that causes in the time of effectively reducing punching press is concentrated the possibility of the side plate fracture that causes; simultaneously; die body is divided into two; live movable dismounting, operation easier during with the minimizing punching operation and operator's working strength by threaded fastener connection and edge.

Fig. 2 is the die body part schematic diagram of the utility model preferred embodiment.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Carbide alloy pole pressing die referring to Fig. 1, Fig. 2, in the present embodiment, comprise upper punch 3, heelpiece 5, sheath 1, die sleeve 2, described sheath 1 is sleeved on die sleeve 2 skins, sheath 1 and the die sleeve 2 common die body securing members of forming, die body 4 is positioned in the middle of the described die sleeve 2, and upper punch 3 is passed through respectively in the upper and lower part, heelpiece 5 is spacing, and described die body 4 is divided into upper die body 41 and lower mold body 42, and the centre connects by threaded fastener 6 and connecting rod.
During use, upper die body 41 and lower mold body 42 are inserted in the die sleeve 2 the filling carbide alloy mixture, on press, upper punch 3 is depressed, compound promptly is shaped to the carbide alloy barred body in cavity, take off die body 42 and heelpiece 5, and the upset mould can be deviate from mould with finished product carbide alloy barred body.
Use this structure mold of the present utility model easy to operate, can avoid more complex operations, improve and improve greatly die life, every secondary mould improved more than ten times in the normal following life-span of operating position, and product glossiness is better.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
