Abstract
The utility model discloses a forming die for drawing out and finishing axial forgings. The forming die comprises an upper die (1) and a lower die (2) which are matched mutually, wherein the upper die (1) and the lower die (2) are connected through a pin (3); the pin (3) is provided with a spring (6); and the center of the lower end surface of the upper die (1) and the center of the upper end surface of the lower die (2) are respectively provided with an upper semicircular groove (4) and a lower semicircular groove (5). The forming die for drawing out and finishing the axial forgings not only has the advantages of simple structure and convenience in manufacture, but also can be used for forging forgings with relatively precise size, good surface finish and reasonable streamline organization distribution.
Description
Technical field
The utility model relates to a kind of loose tool, particularly a kind of loose tool that is used for forged shaft pulling, integer.
Background technology
At present, in forging the process of forged shaft, all rely on manual work to operate to the pulling and the integer of forged shaft; Because workman's technical merit is inconsistent, in process to the forge piece blank reheating pulling, can cause diverse location size on the same blank inhomogeneous, the surface is not bright and clean and the streamline tissue distribution uneven; Simultaneously; In the process of forging forged shaft, reach qualified standard in order to guarantee every forging, when forging, just must leave enough surpluses; So just make that raw material increase the weight of, improved manufacturing cost.
The utility model content
The purpose of the utility model just provides a kind of loose tool that is used for forged shaft pulling, integer that makes forging quality high that has.
The purpose of the utility model is to realize through such technical scheme; A kind of loose tool that is used for forged shaft pulling, integer; Said loose tool comprises the upper die and lower die that cooperatively interact; Said upper die and lower die connect through pin, and pin is provided with spring, saidly are respectively arranged with upper semi-circle connected in star and lower semi-circular groove in the lower surface of patrix and the center, upper surface of counterdie.
Owing to adopted technique scheme, the utility model not only has simple in structure, easily manufactured advantage, and simultaneously, it also has following advantage:
1. adopt its forging, not only accuracy to size is higher, surface smoothness good to make forging, and the distribution of streamline tissue is reasonable simultaneously;
2. because the impression that the forging shape is made up of two semi-circular recesses is controlled, so blank is shaped comparatively fast, the artificial forging of productivity ratio exceeds 1～5 times;
3. adopt loose tool to forge, make allowance less, not only practiced thrift metal material, reduced machining time, and improved operating efficiency and reduced cost.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1; A kind of loose tool that is used for forged shaft pulling, integer; Said loose tool comprises the patrix 1 and counterdie 2 that cooperatively interacts; Said patrix 1 is connected through pin 3 with counterdie 2, and pin 3 is provided with spring 6, and said lower surface and the center, upper surface of counterdie 2 at patrix 1 is respectively arranged with upper semi-circle connected in star 4 and lower semi-circular groove 5.
When forging forged shaft, the counterdie 2 with the utility model is installed in the boss 7 of hammer machine earlier, then forging 8 is put into lower semi-circular groove 5, starts the hammer machine at last and forges; The tup of hammer machine is beating patrix 1 repeatedly up and down, and the hammer power that patrix 1 receives tup moves down, and simultaneously, the reaction force that patrix 1 also receives bullet 6 springs moves up, and moving up and down in the process repeatedly, just forging forged like this.
Claims (1)
1. loose tool that is used for forged shaft pulling, integer; It is characterized in that: said loose tool comprises patrix (1) and the counterdie (2) that cooperatively interacts; Said patrix (1) is connected through pin (3) with counterdie (2); Pin (3) is provided with spring (6), saidly is respectively arranged with upper semi-circle connected in star (4) and lower semi-circular groove (5) in the lower surface of patrix (1) and the center, upper surface of counterdie (2).
