The top circumferential outer wall of the stripping module 8 is in sliding connection with the inner wall of the forging bottom die 3.

[0036] The working principle of the present invention is as follows: round steel is placed in a forging bottom die 3, and the round steel is fixed and kept in the exact center position in the forging bottom die 3 by a self-centering clamp mechanism 4, and the forging impact hammer 31 is intermittently driven to lift a certain distance for free fall motion by an intermittent retracting and releasing rotating mechanism 5, so as to forge the round steel placed in the forging bottom die 3, and after the forging is completed by the continuous and intermittent striking of the round steel by the forging impact hammer 31, the stripping module 8 is driven to move upward by a self-locking lifting mechanism 7, and the forged round steel is lifted upward to complete the separation from the forging bottom die 3, and finally the forged round steel can be taken out.

[0037] Combined with Figure 3 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the self-centering clamp mechanism 4 includes a turntable 41 rotatably arranged on the workbench 1, and the top surface of the turntable 41 is provided with tooth blocks 42 evenly distributed in its circumferential direction. The output shaft of the stepper motor 102 passes through the protective cover 32 and is sleeved and fixed with a transmission gear 43 meshing with the tooth block 42. A plurality of evenly distributed rotating cylinders 44 are rotatably arranged on the circumferential outer wall of the forging bottom die 3, and a transmission gear 45 meshing with the tooth block 42 is sleeved and fixed on the outer end of the rotating cylinder 44. A moving rod 46 is connected to the inner thread of the rotating cylinder 44, and the moving rod 46 passes through the forging bottom die 3 and is connected to a fixed plate 47.

[0038] The working principle of the self-centering clamp mechanism 4: when it is necessary to clamp and fix the round steel placed in the forging bottom die 3, drive the stepper motor 102 to work, and the output shaft of the stepper motor 102 drives the transmission gear 43 to rotate, and the tooth block 42 meshing with the transmission gear 43 drives the turntable 41 to rotate, and then drives the transmission gear 2 45 meshing with the tooth block 42 to rotate, and the rotating drum 44 rotates accordingly. Since the rotating drum 44 is connected to the moving rod 46 with an internal thread, all the moving rods 46 move accordingly until the fixed plate 47 set at the end of the moving rod 46 moves synchronously and fits with the round steel to clamp and fix it.

[0039] Combined with Figure 2 , Attachment Figure 7 , Attachment Figure 8 , Attachment Fig. 9 and attached Fig.10 As shown, the intermittent retractable rotating mechanism 5 includes a slide plate 51 fixed on the mounting arm 21, a pair of slide blocks 52 are slidably provided on the slide plate 51, a moving unit 53 for driving the slide block 52 on one side to move left and right is provided at the bottom, the output shaft of the stepper motor 26 is connected with a main shaft 54, the main shaft 54 ​​passes through the equipment bracket 2 and is sleeved and fixed with a main gear 55, the front side of the main gear 55 is provided with a connecting rod 1 56 rotatably arranged on the main shaft 54, the left and right ends of the connecting rod 1 56 are hinged with a matching gear 1 57 meshing with the main gear 55, the front end of the column head of the matching gear 1 57 is hinged with a connecting rod 2 58, the other end of the connecting rod 2 58 is hinged with a transmission shaft 59, the transmission shaft 59 is sleeved and fixed with a matching gear 2 510 meshing with the matching gear 1 57, the transmission shaft 59 passes through the slide plate 51 and the slide block 52 in sequence and is provided with a friction wheel 511, the friction wheel 511 is connected with the forging impact hammer 31 in rolling friction;

[0040] The interior of the slider 52 is a hollow structure. The transmission shaft 59 on the left side passes through the slider 52 and is located in the inner cavity and is sleeved and fixed with a bevel gear 1 521. A connecting bevel gear 522 meshing with the bevel gear 1 521 is rotatably provided on the inner wall of the slider 52. A rotating rod 523 is rotatably provided on the inner wall of the front side. A bevel gear 2 524 meshing with the connecting bevel gear 522 is sleeved and fixed on the rotating rod 523. After the rotating rod 523 passes through the slider 52, a friction wheel 511 is provided. The moving unit 53 includes a connecting shaft 531 arranged at the bottom of the right slider 52. After the connecting shaft 531 passes through the slide plate 51, a moving block 532 is provided. A mounting block 1 533 is provided at the bottom of one end of the slide plate 51, and a mounting block 2 534 is provided on the middle bottom surface. A threaded connecting rod 535 threadedly connected to the moving block 532 is rotatably provided between the mounting block 1 533 and the mounting block 2 534. A stepping motor 3 536 is installed on the mounting block 1 533, and the stepping motor 3 536 is transmission-connected with the threaded connecting rod 535.

[0041] The working principle of the intermittent retractable rotating mechanism 5 driving the forging impact hammer 31 to move upward is as follows: the stepper motor 2 6 is driven to work, driving the main gear 55 to rotate, and the main gear 55 drives the matching gear 1 57 and the matching gear 2 510 to rotate synchronously, but at this time, the matching gears 2 510 on the left and right sides have the same direction of rotation, resulting in the friction wheels 511 on the left and right sides also having the same direction of rotation, and the forging impact hammer 31 cannot be driven to move upward by friction force, so bevel gears are provided in the slider 52 on one side to cooperate with each other, so that the right transmission shaft 59 and the rotation rod 523 have the same direction of rotation. On the contrary, specifically, the matching gear 2 510 on the right side rotates to drive the transmission shaft 59 to rotate clockwise, thereby driving the friction wheel 511 on the right side to rotate clockwise, and the matching gear 2 510 on the left side drives the transmission shaft 59 to rotate clockwise, so that the bevel gear 1 521 rotates clockwise accordingly. After the steering action of the connected bevel gear 522, the bevel gear 2 524 rotates counterclockwise accordingly, so that the rotating rod 523 drives the friction wheel 511 on the left side to rotate counterclockwise. At this time, the friction wheels 511 on the left and right sides rotate in the opposite direction, which can drive the forging impact hammer 31 to move upward.

[0042] The working principle of the intermittent retractable rotating mechanism 5 to drive the friction wheel 511 to separate from the forging impact hammer 31 is as follows: the stepper motor 3 536 is driven to work, driving the threaded connecting rod 535 to rotate, so that the moving block 532 threadedly connected to the threaded connecting rod 535 moves accordingly, driving the right slider 52 to move away from the forging impact hammer 31 on the slide plate 51. At the same time, the transmission shaft 59 on the right drives the matching gear 2 510 and the connecting rod 2 58 to move, thereby driving the connecting rod 1 56 to rotate clockwise around the main shaft 54, and the connecting rod 2 58 on the left drives the left slider 52 to move away from the forging impact hammer 31 on the slide plate 51, so that the friction wheel 511 moves synchronously in the opposite direction and separates from the forging impact hammer 31.

[0043] Combined with Figure 3 , Attachment Fig.11 , Attachment Fig.12 and attached Fig.13As shown, the self-locking lifting mechanism 7 includes a connecting plate 1 71 with a through groove installed and fixed on the bottom surface of the workbench 1, a pair of slide rails 72 are provided on the side of the connecting plate 1 71, and a connecting plate 2 73 is slidably provided on the slide rail 72. A fixed support arm 74 is installed and fixed between the opposite sides of the connecting plate 2 73, and a support platform 75 is installed and fixed on the top surface of the fixed support arm 74. The top surface of the support platform 75 is provided with a stripping module 8. A fixed seat 1 76 and a fixed seat 2 77 are fixed on the bottom plate of the support frame 101. The side of the fixed seat 1 76 is hinged with a The hydraulic cylinder 78 and the top of the fixed seat 77 are hinged with a V-shaped lever connecting seat 79, and the movable end of the hydraulic cylinder 78 is provided with a connecting column head, which is hinged to the right end of the V-shaped lever connecting seat 79; the middle part of the V-shaped lever connecting seat 79 is provided with a through groove which is slidably connected to the fixed seat 77, and a sliding rod 710 is extended on the front and rear sides of the left end, and a sliding groove 711 which is slidably connected to the sliding rod 710 is reserved on the fixed support arm 74, and a hinge seat 712 which is hinged to the connecting column head is provided at the right end of the V-shaped lever connecting seat 79.

[0044] The working principle of the self-locking lifting mechanism 7 is as follows: when it is necessary to drive the stripping module 8 to move upward to demould the round steel, the hydraulic cylinder 78 is driven to work, the movable end of the hydraulic cylinder 78 is extended to drive the V-shaped lever connecting seat 79 to rotate, and the sliding rod 710 at the upper end of the V-shaped lever connecting seat 79 is connected with the sliding groove 711 in a sliding manner, driving the fixed support arm 74 to move upward, and the stripping module 8 set on the support platform 75 rises and moves accordingly, and after passing through the workbench 1 and the forging bottom die 3, the forged round steel is lifted up to complete the demoulding. In the process of the stripping module 8 moving, due to the special structure of the V-shaped lever connecting seat 79, the round steel forging, the stripping module 8, and the support platform 75 are always in the same vertical straight line with the hinge of the fixed seat 2 77, and the sliding rod 710 is placed in the sliding groove 711 on the fixed support arm 74, which is stable and has a reliable structure. When the hydraulic cylinder 78 is not working, it can achieve self-locking.

[0045] The present invention is specifically implemented as follows: when forging round steel, first, the round steel is placed in the forging bottom die 3, and the stepper motor 102 is driven to work, driving the fixed plate 47 to move synchronously to clamp and fix the forged round steel, and then the stepper motor 2 6 is driven to work, driving the friction wheel 511 to rotate in the opposite direction to lift the forging impact hammer 31. When the forging impact hammer 31 is lifted to a certain height, the stepper motor 3 536 is driven to work, driving the friction wheels 511 on the left and right sides to separate from the forging impact hammer 31, and the forging impact hammer 31 is freely fallen to perform impact forging on the round steel placed in the forging bottom die 3. After one completion, the stepper motor 3 536 is driven to reverse, driving the friction wheels 511 on the left and right sides to fit with the forging impact hammer 31, so that the friction wheel 511 can drive the forging impact hammer 31 to move upward, and the cycle is repeated to repeatedly forge the round steel. When demoulding is required after forging is completed, the hydraulic cylinder 78 is driven to work, driving the demoulding module 8 to move upward, and after passing through the workbench 1 and the forging bottom die 3, the forged round steel is lifted up to complete demoulding, and finally the forged round steel can be taken out.

[0046] It is worth mentioning that the stepper motor 1 102, the stepper motor 2 6, the stepper motor 3 536 and the hydraulic cylinder 78 in the present invention are all existing equipment well known to those skilled in the art, and their circuit connection methods and use control methods are all existing technologies.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
