Description

Thin-wall gear ring convex-concave die

Technical Field

The utility model relates to a stamping die equipment technical field, in particular to thin wall ring gear punch-die.

Background

The male die and the female die are stamping die parts which have the functions of the male die and the female die in the compound die at the same time. In some special technological processes, a thin-wall gear ring convex-concave die is also used, the wall thickness of the convex-concave die is very thin, the size of the convex-concave die is small, and a tooth groove is formed in an outer ring in a winding mode. However, the thin-wall gear ring convex-concave die is difficult to fix in the lower clamping plate, and the convex-concave die is easy to break or break in the working process, so that the production progress is influenced, and the production cost of enterprises is increased.

At present, the technical scheme for fixing the thin-wall gear ring punch-die has two types: the first is to heat and rivet out the hanging table and combine anaerobic adhesive for fixing, and the other is to make a reinforcing hanging table at the bottom of the thin-wall male-female die and use a numerical control optical grinder for processing and molding.

According to the first scheme, due to insufficient strength of the thin-wall convex-concave die, the strength of the thin-wall convex-concave die is further reduced after the thin-wall convex-concave die is heated, knocked and riveted out of the hanging table, normal use is affected, in addition, the problem of damage is also frequently caused in production, the working time is prolonged, the cost is also improved, when the thin-wall convex-concave die is fixed by combining anaerobic adhesive, the thin-wall convex-concave die is difficult to take out of the; the second scheme has the processing cost increased by more than 10 times, and is very high in cost and difficult to be suitable for most enterprises.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a thin wall ring gear convex-concave die through the lower extreme processing external screw thread at ring gear convex-concave die body to a spiro union hanging table packing ring can effectively solve the problem that convex-concave die breaks or breaks easily in process of production, and processing is simple, and is with low costs.

The technical scheme for realizing the purpose is as follows:

the utility model provides a thin wall ring gear punch-die, include:

the male and female die comprises a male and female die body, wherein the lower end of the body is integrally provided with an external thread; and

the wall platform packing ring, the processing of wall platform packing ring has the internal thread hole with above-mentioned external screw thread matched with, and the spiro union of wall platform packing ring is at the lower extreme of body, and when punch-die work received the punching force, its effect was used in the wall platform packing ring, and when punch-die work received the pulling force, its effect was used in connecting thread, has effectively changed the atress mode of punch-die, makes its intensity obtain very big promotion, has reduced the condition that punch-die produced the die break or broke the scheduling problem.

Furthermore, the side face of the hanging platform gasket is integrally and symmetrically provided with two plane structures which are parallel, so that the hanging platform gasket can be conveniently screwed on the body.

Furthermore, the height of the hanging platform gasket is consistent with that of the external thread, so that the structure is more compact, and the screwing strength is improved in a limited space.

Has the advantages that: compared with the prior art, the utility model is different in that, the utility model provides a thin-wall gear ring convex-concave die, including convex-concave die body and a hanging platform gasket, the external screw thread is processed out to the lower extreme of body an organic whole, the hanging platform gasket is connected at the lower extreme of convex-concave die body through the internal thread hole spiro union in the middle of it, when convex-concave die work receives the punching pressure, its effort is mostly acted on hanging platform gasket, and when convex-concave die work receives the pulling force, its effort is mostly acted on the screw thread of interconnect, the atress mode of the effectual change convex-concave die, make the intensity of thin-wall gear ring convex-concave die promote, the problem of being broken or breaking has been greatly reduced; the thin-wall gear ring male and female die is simple in structure, convenient to machine and low in cost, meanwhile, the thin-wall gear ring male and female die is rotatably installed and detached, is beneficial to later maintenance, repair or replacement, and has wider applicability.

Drawings

Fig. 1 is a schematic structural view of a thin-walled ring gear punch-die according to a preferred embodiment of the present application.

Fig. 2 is a schematic structural diagram of the male and female die bodies in the present application.

Fig. 3 is a schematic structural diagram of a pendant washer in the present application.

The structure comprises a body 1, an external thread 11, a hanging platform gasket 2, an internal thread hole 21 and a plane structure 22.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Referring to fig. 1 to 3, the utility model provides a thin wall ring gear punch-die, include:

the convex-concave die body 1 and the hanging platform gasket 2 are characterized in that a section of convex-concave die external thread 11 is processed at the bottom of the body 1, preferably, the thread height is equal to the height of the hanging platform gasket 2, the hanging platform gasket 2 is completely installed on the convex-concave die body 1, the structure is more compact and attractive, the bolt connection strength can be improved to the maximum in a limited space, the thread pitch of the thread can be flexibly selected according to the wall thickness and blanking force of the convex-concave die, and the hanging platform gasket 2 is correspondingly processed into an internal thread hole 21 and is in bolt connection with the lower end of the body 1.

When the punch-die work received the punching force, its effect was used in hanging a packing ring 2, and when the punch-die work received the pulling force, its effect was used in the screw thread of connecting, has effectively changed the atress mode of punch-die, makes its intensity obtain very big promotion, and the structure is more firm, and is more durable, has reduced bad conditions such as blow-off or breaking in the punch-die production, and then has effectively practiced thrift the cost of enterprise.

Preferably, the side face of the hanging platform gasket 2 is integrally and symmetrically provided with two plane structures 22, and the two plane structures 22 are parallel, so that the hanging platform gasket 2 can be conveniently screwed and disassembled on the body 1.

The thin-wall gear ring male and female die is simple in structure, convenient to machine, very convenient to maintain, maintain or replace at a later stage, low in cost and very wide in applicability.

The above embodiments are merely preferred embodiments of the present disclosure, which are not intended to limit the present disclosure, and any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present disclosure, should be included in the scope of the present disclosure.
