The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A forming tool suitable for a press-fitting die comprises a female die, a male die and an ejector rod, wherein a movable die is arranged between the female die and the male die and used for processing the peripheral surface of a workpiece, and the female die is provided with an exhaust hole so as to avoid the phenomenon of incomplete circular arc large punch in the pressing process; the forming part of the male die comprises an extrusion head and a synergistic part, and the length of the forming part is kept unchanged by supplementing the position of the synergistic part when the extrusion head is shortened due to abrasion, so that the service life of the male die is prolonged, and the processing cost is reduced.
The specific embodiment is as follows:
The male die 1 is driven by a press and pressed into the female die 1 to process the inner hole of the workpiece 5. The punch 1 includes a tie bar 12 and a forming portion. The forming section comprises a synergy section 13 and an extrusion head 14. The lower end of the extrusion head 14 is provided with a tapered end to facilitate extrusion of the workpiece 5. The upper end of the extrusion head 14 is connected to a connecting rod 12, the connecting rod 12 being used to connect to a press. The synergy portion 13 is sleeved outside the connecting rod 12 and is supported by the extrusion head 14. Meanwhile, the circumferential surface of the synergy portion 13 is flush with the circumferential surface of the extrusion head 14, and the joint of the synergy portion 13 and the extrusion head 14 is precisely aligned. More specifically, the plurality of synergy portions 13 are provided, and the plurality of synergy portions 13 are different in specification, that is, the thickness of the plurality of synergy portions 13 in the axial direction thereof is different.
As an example of this embodiment, the tapered end of the extrusion head 14 is conical and has a cylindrical structure extending upward along the conical shape. Correspondingly, the synergy part 13 is cylindrical with a hole in the middle, and the connection rod 12 is sleeved with the hole. The diameter of the synergy is the same as the diameter at the cylindrical configuration of the extrusion head 14.
The forming tool suitable for the press-fitting die is used for placing round steel or forging stock into the female die 3 and connecting the material returning rod 4 at the lower end of the female die 3. And starting a press, driving the male die 1 to press downwards into the female die 3, processing an inner hole by utilizing the extrusion action of the male die 1, and after the extrusion forming is finished, performing finish machining on the penetrating rough material in the inner hole to remove, and finally processing a formed workpiece 5. Over a long period of machining the workpiece 5, the lower end of the extrusion head 14 of the punch 1 wears, and the long-term wear causes the length of the extrusion head 14 in the axial direction thereof to become short. At the moment, the synergy part 13 with proper thickness is selected, the synergy part 13 is sleeved on the connecting rod 12, and the synergy part 13 supplements the extrusion head 14 to ensure that the length of the forming part along the axial direction of the forming part is unchanged, so that the inner hole of the workpiece 5 can be better processed, the service life of the male die 1 is effectively prolonged, and the cost for replacing the male die 1 is reduced.
Further, the male die 1 further comprises a connecting body 11. The lower end of the connecting body 11 is connected with a connecting rod 12, and the upper end of the connecting body 11 is connected with a press. When the workpiece 5 is machined, in the process that the male die 1 downwards extrudes the workpiece 5, the upper end of the workpiece 5 and the connecting body 11 are stopped, so that the extrusion depth of the extrusion head 14 into the workpiece 5 is controlled, namely the effective extrusion length of the male die 1 is controlled.
Furthermore, the upper end of the connecting rod 12 is connected with the connecting body 11 through an adjustable connecting mechanism, and the distance from the lower end of the connecting body 11 to the lower end face of the extrusion head 14 can be adjusted, so that the effective extrusion length of the male die 1 can be adjusted. More specifically, the adjustable connection mechanism employs a threaded connection mechanism. The threaded connection comprises an external thread 121 provided on the connecting rod 12 and a threaded hole 111 provided on the connecting body 11. The threaded hole 111 is provided with an internal thread that mates with the external thread 121. The length of the connecting rod 12 screwed into the threaded hole 111 is used for adjusting the effective extrusion length of the male die 1, so that the operation is simple and convenient, and the adjustment is convenient.
Further, the female die 3 is provided with an exhaust hole 31, and the exhaust hole 31 is communicated with the inner cavity of the female die 3. When the workpiece 5 is machined, because the outer shape of the workpiece 5 has a large arc, in order to avoid the situation that the large arc is not filled in the extrusion process, the exhaust hole 31 is arranged.
As an example of the present embodiment, the vent hole 31 extends in the axial direction of the die 3, and the vent hole 31 is provided in plural, and the plurality of vent holes 31 are uniformly arranged in the circumferential direction of the die 3.
Further, in order to improve the machining efficiency, the tool is further provided with a movable die 2. The movable die 2 is used for processing the peripheral surface of the workpiece 5, and can simultaneously complete the processing and forming of an inner hole and the peripheral surface in the primary extrusion process, so that the processing efficiency of the workpiece 5 is improved, and the cost is reduced. Meanwhile, the outer periphery of the connecting body 11 extends to above the movable mold 2. In the extrusion forming process, the connecting body 11 can apply force to the movable mould 2, so that the extrusion effect of the movable mould 2 is realized.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without the technical solutions of the present invention, or the present invention can be directly applied to other occasions without the improvements, and all are within the protection scope of the present invention.
