[0035] Reference Figure 1 、 Figure 2 as well as Figure 4 As shown, the upsetting equipment involved in the embodiment of the present application includes: a frame 100, a fixing device 200 and an upsetting device 300.

[0036] Specifically, the fixing device 200 is provided on the frame 100, and the fixing device 200 is provided with a fixing through hole 210, and the fixing through hole 210 is used for placing the rod-shaped upsetting material; the upsetting device 300 is provided on the frame 100, and the upsetting device 300 includes an upsetting assembly 310, and the upsetting assembly 310 includes a conductive member 311, an upsetting hammer 312 and a fastener 313. The conductive member 311 is provided at one end of the fixing through hole 210 along its axial direction, and the upsetting hammer 312 is connected to the conductive member 311 near the fixing through hole 210. At one end of the fixing member 310, the fastener 313 is connected to the conductive member 311 and the upsetting hammer 312 at the same time, so that the upsetting hammer 312 is fixedly connected to the conductive member 311, and the fastener 313 is detachable relative to the conductive member 311 and the upsetting hammer 312, so that the upsetting hammer 312 can rotate around the central axis of the upsetting hammer 312 relative to the conductive member 311, and the central axis of the fixing through hole 210 is parallel to the central axis of the upsetting hammer 312 and is spaced apart, and the projection of the fixing through hole 210 along its axial direction falls on the upsetting hammer 312.

[0037] In the upsetting device of the present application, the rod-shaped upsetting material can be fixed in the fixing through hole 210. The rod-shaped upsetting material has been fixed by the fixing device 200, so that the upsetting device 300 can upset the rod-shaped upsetting material. During the upsetting process, since the upsetting hammer 312 is connected to the end of the conductive member 311 close to the fixing through hole 210, the conductive member 311 can be energized and heated to upset the upsetting hammer 312. The rod-shaped upsetting material is heated and then upsetting is performed by the heated upsetting hammer 312. Since the central axis of the fixed through hole 210 is parallel to the central axis of the upsetting hammer 312 and spaced apart, and the projection of the fixed through hole 210 along its axial direction falls on the upsetting hammer 312, the rod-shaped upsetting material and the upsetting hammer 312 are in contact and squeezed with each other at non-center positions. After multiple upsetting, the rod-shaped upsetting material will cause the upsetting hammer to When the portion of the upsetting hammer 312 in the upsetting position is deformed, the fastener 313 can be removed from the conductive member 311 and the upsetting hammer 312, so that the upsetting hammer 312 is in contact with and fixedly connected to the conductive member 311. In this way, the upsetting hammer 312 can be rotated relative to the conductive member 311 around the central axis of the upsetting hammer 312, so that the deformed portion of the upsetting hammer 312 is away from the upsetting position, and at the same time, any undeformed portion of the upsetting hammer 312 is in the upsetting position. The fastener 313 is then connected to the conductive member 311 and the upsetting hammer 312 at the same time, so that the upsetting hammer 312 is fixedly connected to the conductive member 311, thereby realizing the replacement of the upsetting portion 3122 of the upsetting hammer 312, so as to avoid the rod-shaped upsetting material from being continuously squeezed against the same portion of the upsetting hammer 312, thereby extending the service life of the upsetting hammer 312.

[0038] Reference Figure 5 as well as Figure 6 As shown, the upsetting hammer 312 is provided with a connecting through hole 3121 along its axial direction, and the connecting through hole 3121 is coaxially arranged with the upsetting hammer 312. The conductive member 311 is provided with a connecting blind hole 3111 connected to the connecting through hole 3121. The central axis of the connecting blind hole 3111 is parallel to the central axis of the fixing through hole 210 and is arranged at intervals. The fastener 313 is simultaneously penetrated through the connecting through hole 3121 and the connecting blind hole 3111, and is interference-connected with the connecting blind hole 3111.

[0039] Specifically, the fastener 313 is a screw, which can meet the requirement of fastening the upsetting hammer 312 and the conductive member 311 to be connected tightly, and can also meet the requirement of facilitating the disassembly of the fastener 313 .

[0040] In this embodiment, since the fastener 313 is simultaneously provided in the connecting through hole 3121 and the connecting blind hole 3111, and is interference-connected with the connecting blind hole 3111, the fastener 313 can realize the fastening connection between the upsetting hammer 312 and the conductive member 311. Since the connecting through hole 3121 and the upsetting hammer 312 are coaxially arranged, the central axis of the connecting blind hole 3111 is parallel to the central axis of the fixed through hole 210 and is spaced apart. In this way, when the upsetting hammer 312 is fastened to the conductive member 311, the central axis of the upsetting hammer 312 can be aligned with the central axis of the fixed through hole 210. The central axes of the through holes 210 are parallel and spaced apart so that the rod-shaped upsetting material contacts and squeezes the non-center portion of the upsetting hammer 312, thereby facilitating the replacement of the upsetting portion 3122 of the upsetting hammer 312. At the same time, when the upsetting portion 3122 of the upsetting hammer 312 needs to be replaced, it is only necessary to remove the fastener 313 from the conductive member 311 and the upsetting hammer 312, so that the replacement process of the upsetting portion 3122 of the upsetting hammer 312 is convenient and quick. At the same time, when the used upsetting hammer 312 needs to be replaced, the convenience of replacement can also be improved.

[0041] Continue to refer to Figure 5 as well as Figure 6 As shown, the upsetting hammer 312 includes an upsetting portion 3122 and a limiting portion 3123. The limiting portion 3123 is connected to one end of the upsetting portion 3122 away from the fixed through hole 210. The conductive member 311 is provided with a first limiting groove 3112 with an opening toward the fixed through hole 210. The limiting portion 3123 is arranged in the first limiting groove 3112 and abuts against the groove wall of the first limiting groove 3112 along the radial direction of the upsetting hammer 312.

[0042] Specifically, the first limiting groove 3112, the limiting portion 3123 and the upsetting portion 3122 are coaxially arranged, and the first limiting groove 3112 is connected to the connecting blind hole 3111, so that the fastener 313 can pass through the upsetting portion 3122 and the center axis of the limiting portion 3123 in sequence, thereby improving the connection tightness between the upsetting hammer 312 and the conductive member 311, and at the same time avoiding the limiting portion 3123 from rotating around the axial direction of the limiting portion 3123 in the first limiting groove 3112, thereby improving the stability of the upsetting process.

[0043] In this embodiment, the rod-shaped upsetting material contacts and squeezes each other at a non-center portion of the upsetting portion 3122 to achieve upsetting of the rod-shaped upsetting material. Since the opening of the first limiting groove 3112 is arranged in the first limiting groove 3112 toward the limiting portion 3123, and is abutted against the radial groove wall of the first limiting groove 3112 along the upsetting hammer 312, in this way, during the upsetting process of the rod-shaped upsetting material, the limiting portion 3123 can be limited by the first limiting groove 3112 to prevent the upsetting hammer 312 from moving along its radial direction, thereby improving the upsetting quality and the safety of the upsetting process.

[0044] Reference Figure 3 As shown, the upsetting device 300 further includes a first driving member 320 , which is disposed on the frame 100 and connected to the upsetting assembly 310 , and is used to drive the upsetting assembly 310 to move axially relative to the frame 100 along the fixed through hole 210 .

[0045] In this embodiment, since the first driving member 320 is connected to the upsetting assembly 310 and is used to drive the upsetting assembly 310 to move axially relative to the frame 100 along the fixed through hole 210, the first driving member 320 can drive the upsetting assembly 310 to approach or move away from the rod-shaped upsetting material along the axial direction of the fixed through hole 210 to achieve contact or separation between the upsetting assembly 310 and the rod-shaped upsetting material.

[0046] Reference Figure 3 as well as Figure 7 As shown, the upsetting device 300 also includes a detection component 330, which includes a detection member 331 and a displacement sensor 332. The detection member 331 is connected to the upsetting component 310 or the first driving member 320, and the displacement sensor 332 is used to detect the axial movement distance of the detection member 331 along the fixed through hole 210.

[0047] Specifically, the detection component 330 also includes a controller (not shown), and the displacement sensor 332 and the first driving member 320 are electrically connected to the controller. When the displacement sensor 332 detects that the distance moved by the detection member 331 reaches a preset distance, it sends a distance signal to the controller. After receiving the distance signal, the controller sends an instruction to the first driving member 320 to stop driving the first driving member 320, thereby stopping the forging component 310 from moving axially along the fixed through hole 210.

[0048] In this embodiment, the displacement sensor 332 can detect the axial movement distance of the detection member 331 along the fixed through hole 210 to detect the axial movement distance of the upsetting assembly 310 along the fixed through hole 210, thereby controlling the upsetting length of the rod-shaped upsetting material.

[0049] Reference Figure 7 As shown, the detection assembly 330 also includes a first connecting member 333 connected to the upsetting assembly 310. The first connecting member 333 is extended radially along the fixing through hole 210 and protrudes from the upsetting assembly 310. The detection member 331 is connected to one end of the first connecting member 333 protruding from the upsetting assembly 310. The displacement sensor 332 and the first connecting member 333 are spaced apart axially along the fixing through hole 210, and the infrared rays emitted by the displacement sensor 332 fall on the detection member 331.

[0050] In this embodiment, since the displacement sensor 332 and the first connecting member 333 are arranged at intervals along the axial direction of the fixed through hole 210, and the displacement sensor 332 and the first connecting member 333 are arranged at intervals along the axial direction of the fixed through hole 210, and the infrared ray emitted by the displacement sensor 332 falls on the detection member 331, the distance between the displacement sensor 332 and the detection member 331 can be determined by the distance of the infrared ray reflected back to the displacement sensor 332, thereby determining the displacement by the change in the distance of the infrared ray reflected back to the displacement sensor 332. The distance between the sensor 332 and the detection member 331 changes, thereby realizing the detection of the axial movement distance of the upsetting assembly 310 along the fixed through hole 210. In this process, since the first connecting member 333 is extended radially along the fixed through hole 210 and protrudes from the outside of the upsetting assembly 310, the detection member 331 is connected to the end of the first connecting member 333 protruding from the upsetting assembly 310. In this way, it is possible to avoid interference with the reflection path of the infrared rays caused by the upsetting assembly 310, thereby improving the accuracy of the detection of the movement distance of the upsetting assembly 310.

[0051] Continue to refer to Figure 7 As shown, the detection component 330 also includes a guide member 334, which is connected to the frame 100, and the guide member 334 and the upsetting component 310 are arranged at radial intervals along the fixed through hole 210, and the guide member 334 is provided with a second limiting groove 3341 extending axially along the fixed through hole 210, the first connecting member 333 is passed through the second limiting groove 3341, and slides axially along the fixed through hole 210 relative to the second limiting groove 3341, and the first connecting member 333 is in contact with the groove wall of the second limiting groove 3341.

[0052] Specifically, the first connecting member 333 fits against the second limiting groove 3341 along the radial direction of the fixing through hole 210 .

[0053] In this embodiment, since the first connecting member 333 is passed through the second limiting groove 3341 and slides axially along the fixed through hole 210 relative to the second limiting groove 3341, it is possible to ensure that the first connecting member 333 can move axially along the fixed through hole 210, thereby ensuring that the detection member 331 can move axially along the fixed through hole 210. At the same time, since the first connecting member 333 fits the groove wall of the second limiting groove 3341, it is possible to avoid the first connecting member 333 from deflecting during the movement, thereby improving the stability of the detection member 331 during the movement and improving the accuracy of detecting the moving distance of the upsetting assembly 310.

[0054] Specifically, refer to Figure 3As shown, the upsetting assembly 310 includes a second connecting member 314, one end of the second connecting member 314 is connected to the first driving member 320, the other end of the second connecting member 314 is connected to the conductive member 311, and the end of the second connecting member 314 away from the detection member 331 is connected to the second connecting member 314, so as to realize the connection between the upsetting assembly 310 and the first driving member 320 and the detection assembly 330 through the second connecting member 314.

[0055] Specifically, continue to refer to Figure 3 As shown, the upsetting assembly 310 includes an insulating member 315 , which is disposed between the second connecting member 314 and the conductive member 311 to isolate the conductive member 311 from the second connecting member 314 , thereby preventing the upsetting device from leaking electricity.

[0056] Reference Figure 8 As shown, the fixing device 200 includes a first fixing component 220 and a second fixing component 230. The first fixing component 220 and the second fixing component 230 are both arranged on the frame 100, and the first fixing component 220 is used to clamp one end of the rod-shaped upsetting material close to the upsetting device 300, and the second fixing component 230 is used to clamp one end of the rod-shaped upsetting material away from the upsetting device 300. The fixing through hole 210 is at least partially located in the first fixing component 220 and at least partially located in the second fixing component 230.

[0057] In this embodiment, the first fixing assembly 220 and the second fixing assembly 230 can respectively clamp the two ends of the rod-shaped upsetting material to improve the fixing stability of the fixing device 200 on the rod-shaped upsetting material, thereby improving the parallelism between the central axis of the rod-shaped upsetting material and the central axis of the upsetting hammer 312, thereby improving the upsetting quality of the rod-shaped upsetting material.

[0058] Continue to refer to Figure 8 As shown, the first fixing assembly 220 includes a first fixing member 221, a second fixing member 222 and a second driving member 223. The second fixing member 222 is fixedly arranged on the frame 100 and is spaced apart from the first fixing member 221. The second driving member 223 is arranged on the frame 100 and connected to the first fixing member 221. The second driving member 223 is used to drive the first fixing member 221 to approach the second fixing member 222 to define a first clamping hole 211 between the first fixing member 221 and the second fixing member 222. The first clamping hole 211 is one of the hole sections of the fixing through hole 210.

[0059] Specifically, the first fixing member 221 and the second fixing member 222 are spaced apart from each other along the radial direction of the fixing through hole 210 .

[0060] In this embodiment, since the second fixing member 222 is spaced apart from the first fixing member 221, the second driving member 223 is connected to the first fixing member 221. In this way, the first fixing member 221 can be driven close to the second fixing member 222 by the second driving member 223, so that the rod-shaped upsetting material can be clamped by the first fixing member 221 and the second fixing member 222, so that at least a portion of the rod-shaped upsetting material can be fixed in the first clamping hole 211, so as to facilitate upsetting of the rod-shaped upsetting material.

[0061] Continue to refer to Figure 8 As shown, the second fixing assembly 230 includes a third fixing member 231, a fourth fixing member 232 and a third driving member 233. The third fixing member 231 and the fourth fixing member 232 are spaced apart. The third driving member 233 is set on the frame 100 and is connected to the third fixing member 231 and the fourth fixing member 232 at the same time. The third driving member 233 is used to drive the third fixing member 231 and the fourth fixing member 232 to approach each other, so as to define a second clamping hole 212 between the third fixing member 231 and the fourth fixing member 232. The second clamping hole 212 is one of the hole sections of the fixing through hole 210, and the second clamping hole 212 is coaxially arranged with the first clamping hole 211.

[0062] Specifically, the third fixing member 231 and the fourth fixing member 232 are spaced apart from each other along the radial direction of the fixing through hole 210 .

[0063] Specifically, there are two third driving members 233, one of which is connected to the third fixing member 231 and the fourth fixing member 232 along one side of the radial direction of the fixing through hole 210, and one of which is connected to the third fixing member 231 and the fourth fixing member 232 along the other side of the radial direction of the fixing through hole 210. The two third driving members 233 drive both sides of the third fixing member 231 to move simultaneously, and drive both sides of the fourth fixing member 232 to move simultaneously, so as to improve the degree of synchronization between various parts of the third fixing member 231 and various parts of the fourth fixing member 232 during the movement process.

[0064] In this embodiment, since the third fixing member 231 and the fourth fixing member 232 are arranged at intervals, the third driving member 233 is connected to the third fixing member 231 and the fourth fixing member 232 at the same time. In this way, the third driving member 233 can drive the third fixing member 231 and the fourth fixing member 232 to approach each other, so that the third fixing member 231 and the fourth fixing member 232 can clamp the rod-shaped upsetting material so that at least a portion of the rod-shaped upsetting material can be fixed in the second clamping hole 212. Since the second clamping hole 212 and the first clamping hole 211 are coaxially arranged, when the rod-shaped upsetting material is clamped in the second clamping hole 212 and the first clamping hole 211 at the same time, the parallelism between the central axis of the rod-shaped upsetting material and the central axis of the upsetting hammer 312 can be improved, thereby improving the upsetting quality of the rod-shaped upsetting material.
