The processing method of the die comprises the following steps of: processing the outer ring and the inner ring separately, then performing press-fitting, respectively increasing the positioning pin holes which are interrelated with the reference on the inner ring and the outer ring of the die, using a clamp to well set the positions by utilizing the pin holes and further performing the press-fitting, wherein the axial lines of the positioning pin holes of the inner ring and the outer ring and the reference are interrelated on the same central plane and the reference is the central line of the key slot. By adopting the die, the complex shape of an inner cavity and the requirements on the position of the positioning reference of the outer ring can be ensured; simultaneously, the die is low in processing cost and high in processing efficiency, and can overcome the deficiencies in the prior art and meet the requirements of mass production.
Description
Technical field
The present invention relates to mould and mold machining technology field.
Background technology
The auto parts machineries such as existing multiple position press production flange shaft, universal joint, for example Japanese 2000T multiple position press, the feature of this forging is inner chamber and outer shape complexity and has status requirement, utilize the positional precision of pressing machine die carrier die sleeve part keyway, all adopt key connecting locate mode can reach this requirement by upper and lower mould.Forming station counterdie outer ring keyway and cavity shape must ensure exact position relation for this reason, because race diameter is large, if be press-fitted with conventional heat treatment, rear processing mode mold weight is large, difficulty is loaded and unloaded, difficult processing, outer ring is press-fitted rear easy plucking repeatedly, can not reuse, once and mould damages entirety is scrapped, be press-fitted in process easily failure position relation.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming on above traditional diamond-making technique, provide a kind of major diameter Internal and external cycle to have status requirement mould and processing method thereof, the processing method that adopts outer ring inner ring separate machined to be press-fitted again, ensure the status requirement of inner chamber complicated shape and outer ring positioning datum, simultaneously processing cost is low, working (machining) efficiency is high, to overcome the deficiencies in the prior art, meet the requirement of batch production.
The invention provides following technical scheme for solving the problems of the technologies described above:
A kind of major diameter Internal and external cycle has the mould of status requirement, comprise inner ring, outer ring, keyway, keyway ring leaves the periphery in outer ring, wherein: increase respectively with position degree and require consistent dowel hole at described mould Internal and external cycle, the axis of Internal and external cycle dowel hole is relevant to benchmark on same central plane, the center line that described benchmark is described keyway.
A kind of major diameter Internal and external cycle has the processing method of status requirement mould, described processing method is to adopt outer ring inner ring separate machined to be press-fitted again, increase respectively the dowel hole relevant to benchmark at mould Internal and external cycle, the axis of Internal and external cycle dowel hole is relevant to benchmark on same central plane, described benchmark is the center line of described keyway, utilizes pin-and-hole that position is reserved and is press-fitted with fixture.
There is a kind of preferred version of the processing method of status requirement mould as major diameter Internal and external cycle of the present invention, wherein: before described being press-fitted, be press-fitted surface uniform at Internal and external cycle and smear one deck graphite spray.
There is a kind of preferred version of the processing method of status requirement mould as major diameter Internal and external cycle of the present invention, wherein: described in to be press-fitted process be that mould is sidelong, after putting fixation clip well, fix pin A, first make pin A coordinate with outer ring pin-and-hole, rotary inner ring coincide the dowel hole on pin B and inner ring and fixes pin B, strike tight inner ring with rod, take off pin A, pin B and fixation clip, be press-fitted towards upper entirety and be placed on hydraulic press operating platform face and be press-fitted.
There is a kind of preferred version of the processing method of status requirement mould as major diameter Internal and external cycle of the present invention, wherein: described rod can be copper rod, aluminium bar, the barred body that the materials such as tin bar are softer.
Major diameter Internal and external cycle of the present invention has the advantage of status requirement mould and processing method thereof to be: the processing method that adopts outer ring inner ring separate machined to be press-fitted again, ensure the status requirement of inner chamber complicated shape and outer ring positioning datum, simultaneously processing cost is low, working (machining) efficiency is high, to overcome the deficiencies in the prior art, meet the requirement of batch production.Adopt the method outer ring can standardization, seriation and can Reusability, outer ring coordinates not plucking repeatedly simultaneously, can reuse, failure position relation not in being press-fitted, has shortened the mould production time, has reduced mould input, has reduced the production cost of forging.
Brief description of the drawings
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is mould side generalized section.
Fig. 2 is mould top view schematic diagram.
Fig. 3 is fixation clip schematic diagram.
Fig. 4 is that mould is press-fitted schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described, as shown in the figure, wherein: 1. inner ring, 2. outer ring, 3. keyway, 4. outer ring dowel hole, 5. inner ring dowel hole, 6. fixation clip, 7. pin A, 8. pin B, is 9. press-fitted face.
There is as shown in Figure 1 and Figure 2 the mould of status requirement for a kind of major diameter Internal and external cycle, this mould comprises inner ring 1, outer ring 2, keyway 3, keyway ring leaves the periphery in outer ring, it is characterized in that: increase respectively with position degree and require consistent outer ring dowel hole 4 and inner ring dowel hole 5 at described mould Internal and external cycle, the axis of Internal and external cycle dowel hole is relevant to benchmark on same central plane.Described benchmark is the center line of described keyway.
Described die processing method is to adopt outer ring inner ring separate machined to be press-fitted again, increase respectively the dowel hole relevant to benchmark at mould Internal and external cycle, the axis of Internal and external cycle dowel hole is relevant to benchmark on same central plane, utilize pin-and-hole that position is reserved and is press-fitted with fixture, before described being press-fitted, be press-fitted surface uniform at Internal and external cycle and smear one deck graphite spray.The effect that surface uniform is smeared graphite spray is to play a lubrication in the process of being press-fitted, plucking not, is convenient to reuse outer ring.
