Abstract
The utility model relates to a once processing die of internal and external teeth of a gear. The once processing die comprises an internal gear die, an external gear die and an external die sleeve, wherein the internal gear die is arranged in the center of a gear processing die and has a solid structure with a precise gear, the external gear die and the internal gear die are arranged coaxially, the interior of the external gear die is processed into a tooth-shape cavity, the external die sleeve sheaths outside the external gear die, the bottoms of the internal gear die and the external gear die are connected by a base plate, and the base plate has a plurality of through holes for accommodating ejector rods. Internal and external teeth of the gear are processed once by the internal gear die and the external gear die, so that the problem that the internal teeth and the external teeth affect each other in processing is solved, and the precision of the gear is improved; the internal teeth and the external teeth are processed simultaneously, the processing material is saved, so that the once processing die has very strong market utility value.
Description
Technical field
The utility model belongs to gear forming technical field, is specifically related to a kind of Gear Processing mould.
Background technology
Cold extrusion is placed on metal blank in cold extrusion die cavity exactly, at room temperature, exerts pressure to blank by punch fixing on forcing press, makes metal blank produce plastic deformation and makes the processing method of part.At present, China can be to plumbous, tin, the metals such as aluminium, copper, zinc and alloy thereof, mild steel, medium carbon steel, tool steel, low-alloy steel and stainless steel carry out cold extrusion, even also can carry out the cold extrusion of certain deflection to bearing steel, high-carbon high-aluminium alloy tool steel, high-speed steel etc.Aspect extrusion equipment, China has possessed the ability of Design and manufacture tonnage squeezing presses at different levels.Except adopting universal machine forcing press, hydraulic press, cold extrusion press, also successfully adopt friction press and high speed high energy equipment to carry out cold extrusion production.
In prior art, all adopt the method for interior external tooth separate machined for the gear with interior external tooth, process after a profile of tooth, the meeting that is difficult to avoid in another profile of tooth of processing exerts an influence to the profile of tooth of having processed, and finally has influence on the precision of whole gear.
Utility model content
For the problems referred to above, the utility model proposes a kind of mould of interior external tooth time processing, the problem that interacts while having solved the processing of interior external tooth, has improved the precision of gear; Simultaneously, external tooth is processed simultaneously, saves rapidoprint, has very strong market value.
The technical solution of the utility model is: external tooth time processing mould in a kind of gear, comprises internal gear mould, external gear mould and outer die casing; Described internal gear mould is positioned at Gear Processing mold center position, is the entity structure with the accurate gear teeth; Described external gear mould and internal gear mould coaxially arrange, and inside is processed as profile of tooth cavity; Described outer die casing is set in external gear mould outside; Described internal gear mould is connected with backing plate with external gear mould bottom, has the through hole of some placement push rods on described backing plate.
Further, described external gear mould is made up of 65Nb mould steel or alloy tool steel, and described outer die casing is made up of H13 mould steel or 9CRWMN mould steel.Because the making material of outer die casing is toughness material, so possess good plasticity, can there is not the destruction of cracking and so in the internal mold that can adequately protect in the process of cold-extruded.
Further, described external gear mould adopts Small Taper interference fit to be connected with outer die casing, and the magnitude of interference between described external gear mould and outer die casing is between 1-1.5mm.Adopt pressurization hot jacket method in the time that outer die casing temperature is higher, be pressed in the outside of internal mold, cooling after, internal mold and outer die casing closely link together.
Further, the gear teeth number of described internal gear mould is 6.
Further, the gear teeth number of the inner processing of described external gear mould profile of tooth cavity is 13.
The beneficial effects of the utility model are: utilize the interior external tooth of internal gear mould and external gear mould time processing gear, the problem that interacts while having solved the processing of interior external tooth, has improved the precision of gear; Simultaneously, external tooth is processed simultaneously, saves rapidoprint, has very strong market value.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model Gear Processing mould.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, external tooth time processing mould in a kind of gear, comprises internal gear mould 4, external gear mould 1 and outer die casing 2; Described internal gear mould 4 is positioned at Gear Processing mold center position, is the entity structure with 6 accurate gear teeth; Described external gear mould 1 coaxially arranges with internal gear mould 4, and inside is processed as profile of tooth cavity, and the gear teeth number of the inner processing profile of tooth of described external gear mould 1 cavity is 13; Described outer die casing 2 is set in external gear mould 1 outside; Described internal gear mould 4 is connected with backing plate 3 with external gear mould 1 bottom, has the through hole 5 of some placement push rods on described backing plate 3.Utilize the interior external tooth of internal gear mould and external gear mould time processing gear, the problem that interacts while having solved the processing of interior external tooth, has improved the precision of gear; Simultaneously, external tooth is processed simultaneously, saves rapidoprint, has very strong market value.
Further, described external gear mould 1 is made up of 65Nb mould steel or alloy tool steel, and described outer die casing 2 is made up of H13 mould steel or 9CRWMN mould steel.Because the making material of outer die casing is toughness material, so possess good plasticity, can there is not the destruction of cracking and so in the internal mold that can adequately protect in the process of cold-extruded.
Further, described external gear mould 1 adopts Small Taper interference fit to be connected with outer die casing 2, and the magnitude of interference between described external gear mould 1 and outer die casing 2 is between 1-1.5mm.Adopt pressurization hot jacket method in the time that outer die casing temperature is higher, be pressed in the outside of internal mold, cooling after, internal mold and outer die casing closely link together.
Although the utility model discloses as above with preferred embodiment, so it is not in order to limit the utility model.Under the utility model, in technical field, have and conventionally know the knowledgeable, not departing from spirit and scope of the present utility model, when being used for a variety of modifications and variations.Therefore, protection domain of the present utility model is when being as the criterion depending on claims person of defining.
