Abstract
The utility model relates to a designed shaping tool for an internal tooth gear ring of an oil pump, in particular to a shaping tool for the internal tooth gear ring. The shaping tool for the internal tooth gear ring comprises a base, a positioning ring, a stress ring and a punch. The punch is installed on the base, the stress ring is connected with the punch in a sleeved mode and connected with the base in a matched mode, and the positioning ring is connected with the stress ring in a sleeved mode and connected with the base in a matched mode. The shaping tool for the internal tooth gear ring is simple in structure and high in machining precision and effectively guarantees abrasion resistance of a workpiece, and production and machining cost is saved.
Description
Technical field
The utility model designs a kind of oil pump internal-gear circle apparatus for shaping, refers to especially a kind of internal-gear circle shaping tool.
Background technology
The internal-gear circle of oil pump gear pair adopts the stock powder metallurgy forming, can produce distortion unavoidably during owing to sintering, add subsequent storage, carrying etc., part can produce a certain amount of stress sex change under the effect of internal stress, make the circularity of gear ring poor, cause part can't directly process use, because of the structure particularity of internal-gear, use the method for processing to revise that not only difficulty is large, and cost is also higher, can't guarantee that the precision of internal-gear meets demand.
The utility model content
The technical problem that one, will solve
The purpose of this utility model is for the existing the problems referred to above of prior art, and the spy provides a kind of interior whole gear ring shaping tool, and it is large effectively to have solved the prior art difficulty of processing, and cost is high, the defective that standard can't meet.
Two, technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of internal-gear circle shaping tool, includes base, centring ring, circle stress and drift; Above-mentioned drift is installed on the base, and above-mentioned circle stress is socketed drift and is connected with base, and above-mentioned centring ring is socketed circle stress and is connected with base.
As optimization, be provided with the gusseted piece on the above-mentioned base.
Three, the beneficial effects of the utility model
Internal-gear circle shaping tool of the present utility model is simple in structure, and machining accuracy is high, has effectively guaranteed wear resistence and the wearability of workpiece, has saved the production and processing cost.
Description of drawings
Fig. 1 is the structure chart of internal-gear circle shaping tool of the present utility model.
Among the figure, 1 is that base, 2 is that centring ring, 3 is circle stress, and 4 is drift, and 5 is the gusseted piece.
The specific embodiment
Below in conjunction with accompanying drawing internal-gear circle shaping tool of the present utility model is described further:
Embodiment: as shown in Figure 1, internal-gear circle shaping tool of the present utility model includes base 1, centring ring 2, circle stress 3 and drift 4; Above-mentioned drift 4 is installed on the base 1, and above-mentioned circle stress 3 is socketed drifts 4 and is connected with base 1, and above-mentioned centring ring 2 is socketed circle stresses 3 and is connected with base 1.
Be provided with gusseted piece 5 on the above-mentioned base 1, make the structure of base more firm, durable.
When the internal-gear circle shaping tool of present embodiment is worked, workpiece is placed between drift 4 and the base 1, carry out the cold extrusion trimming, effectively reduced the deviation from circular from of internal-gear circle, guaranteed the uniformity of accessory size, improved fineness and the precision of piece surface, made piece surface form one deck compacted zone and flow harden layer by the cold extrusion shaping, corrosion resistance and the wearability of part have been improved, the service life of having improved part.
Internal-gear circle shaping tool of the present utility model is simple in structure, and machining accuracy is high, has effectively guaranteed wear resistence and the wearability of workpiece, has saved the production and processing cost.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
