Abstract
The utility model relates to a spur gear blank precision forging forming die, including last mould die body, last mould shaping piece, lower die -cutting rule, lower mould shaping piece, lower mould profile of tooth shaping piece, lower mould die body, lower mould circle stress, lower mould ejector pin, lower mould star frame, characterized by: lower mould shaping piece appearance and lower mould profile of tooth shaping piece sliding fit, the hole and the lower die -cutting rule sliding fit of lower mould shaping piece, the die -cutting rule links together with the lower mould die body down. Its advantage is: through reasonable in design's forging forming mould and corresponding technology, realized that the hole of gear and profile of tooth once take shape. On mould structure, designed and punched a hole and closed extrusion molding's compound mould into having simultaneously, effectively reduced forging manufacturing procedure, also avoid the end multiple operation such as to punch a hole simultaneously and given into the deformation that the generating gear blank led to the fact.
Description
Technical field
The utility model relates to a kind of straight spur gear blank precision forging mould, is specifically related to a kind of forging and molding mould of the straight spur gear blank with profile of tooth and endoporus, belongs to forging mold field.
Background technology
Comprise profile of tooth (steel) gear blank in modern forging is produced, have more forging according to different requirements and purposes and shape technique, be shaped for big-and-middle-sized gear forging, most needs even finally could complete whole shaping work to the heating for multiple times that blank carries out different temperatures compared with multiple operation.Because wrought forged gears blank has higher requirement to blank surface quality and local (toothed section) allowance (being less than 0.5mm) dimensional tolerance, forging goes out heart portion through hole again simultaneously, determines high requirement during its blank forming.
The present utility model is for the straight spur gear blank of a median size with profile of tooth and endoporus, once completes forging and molding after adopting prefabricated blank through designed assembling die.
Summary of the invention
The purpose of this utility model be to provide a kind of adopt prefabricated blank after once to complete the straight spur gear blank precision forging mould of forging and molding through designed assembling die.
The purpose of this utility model is achieved in the following ways:
The utility model comprises patrix die body, upper die forming block, counterdie cutting knife, counterdie forming blocks, counterdie profile of tooth forming blocks, counterdie die body, counterdie circle stress, counterdie push rod, counterdie starframe, it is characterized in that: counterdie forming blocks profile and counterdie profile of tooth forming blocks are slidably matched, hole and the counterdie cutting knife of counterdie forming blocks are slidably matched; Counterdie cutting knife and counterdie die body link together.
The utility model has the advantages that: by forging and molding mould reasonable in design and corresponding technique, the endoporus and the profile of tooth that achieve gear are once-forming.On mould structure, be designed to the composite die simultaneously with punching and Closed Extrusion shaping, effectively reduced forging manufacturing procedure, it also avoid the distortion that the multiple operation such as last punching cause to formed gear blank simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing, the utility model comprises patrix die body 1, upper die forming block 2, counterdie cutting knife 3, counterdie forming blocks 4, counterdie profile of tooth forming blocks 5, counterdie die body 6, counterdie circle stress 7, counterdie push rod 8 and counterdie starframe 9.Counterdie forming blocks 4 profile and counterdie profile of tooth forming blocks 5 are slidably matched, and its hole and counterdie cutting knife 3 are slidably matched; Counterdie cutting knife 3 is fastened together by soket head cap screw 10 and counterdie die body 6.
The utility model be for former blank preform after middle blank, adopt mould of the present utility model to complete the forging and molding of gear blank.Middle blank is obtained after once heating by another mould.In the middle of adopting, the object of blank is for obtaining the structure matched with finish-forging lower mode cavity, for finish-forging is shaped the preparation carried out further in structure and size.Specific works process is as follows:
After blank heating to initial forging temperature, in stroke, complete middle blank forming work by prefabricated blank mould in first time of press ram, middle blank is spun upside down 180 ° and put into counterdie die body die cavity of the present utility model, counterdie cutting knife 3(is also the cutting knife of blank gross weight in the middle of cutting off) enter in the blind hole of middle blank, and positioning action is played to middle blank, in press ram second time stroke, upper, when counterdie die body closes, according to position relationship, first the punch structure be made up of counterdie cutting knife 3 and upper die forming block 2 endoporus completes and removes rushing of gross weight in the middle of pre-forging, continue in descending process at patrix, by upper die forming block 2, counterdie forming blocks 4, the near closed hollow ring that counterdie profile of tooth forming blocks 5 and counterdie cutting knife 3 are formed completes the bulk forming to blank in the middle of residue.After completing the shaping of finish-forging part, forcing press return, while upper and lower mould separates, the gear blank part be shaped is under the effect of equipment bottom knockout mechanism, the counterdie push rod 8 pairs of counterdie forming blocks 4 be distributed in counterdie die body respectively by counterdie starframe 9, three upwards eject, finally by forging ejection die.In the middle of staying the pre-forging in upper die forming block 2 endoporus, gross weight comes off naturally, completes whole forming processes of a forging.
The utility model can adopt different mounting structures all can realize forging and molding work on fly press or crank press.
