The cold heading workpiece 3 is moved to the next cold heading hole 11 for cold heading treatment. The cold heading workpiece 3 is clamped by the clamping loading piece to ensure that the cold heading workpiece 3 is located at the cold heading hole 11, and then the cold heading head 2 is moved to move the cold heading workpiece 3 into the cold heading hole 11, and then the clamping loading piece is passively opened to realize the cold heading treatment of the cold heading head 2, and then the cold heading workpiece 3 is extruded by the discharge rod 12, and then the cold heading workpiece 3 is passively conveyed by the conveying piece, so as to realize the passive conveying of the cold heading workpiece 3, and realize the conveying during the movement of the cold heading head 2 and the discharge rod 12, without increasing the conveying time, saving the time of cold heading, and improving the conveying efficiency.

[0049] In an embodiment further provided by the present invention, the clamping and loading parts include two first connecting rods 41 arranged on the cold heading machine body 1, the ends of the two first connecting rods 41 are fixedly connected with fan gears 42, and the two first connecting rods 41 are fixedly connected with connecting plates 43, the ends of the two connecting plates 43 are fixedly connected with clamping plates 44, the two clamping plates 44 are adapted to the cold heading workpiece 3, the connecting rods are connected to the sliding plate 61, and a groove is opened on the front side of the cold heading machine body 1, which is used to ensure that the connecting rods and other parts do not cause motion interference with the cold heading machine body 1 when the sliding plate 61 slides.

[0050] Furthermore, the clamping and loading member also includes a double-sided rack 46 , which is in driving engagement with the two sector gears 42 , a guide hole 47 is provided in the double-sided rack 46 , and the two connecting plates 43 are fixedly connected by a tension spring 45 .

[0053] Furthermore, the conveying member also includes two push tubes 64 slidably arranged in the cold heading machine, a push rod 65 is slidably arranged in the push tube 64, and a second ratchet plate 66 adapted to the first ratchet plate 63 is fixedly connected to the end of the push rod 65, a guide groove 651 is opened outside the push rod 65, and a guide block 641 adapted to the guide groove 651 is fixedly connected to the inner wall of the push tube 64, and a clamping spring 67 is arranged on the outer sleeve of the guide block 641, and the guide groove 651 is composed of a straight groove and a spiral groove. When the guide block 641 slides in the straight groove, The push tube 64 only slides on the surface of the push rod 65. When the guide block 641 moves to the spiral groove, the push tube 64 moves so that the push tube 64 slides on the surface of the push rod 65, and at the same time, the push rod 65 rotates, thereby realizing the rotation of the second ratchet plate 66. When the second ratchet plate 66 rotates to drive the first ratchet plate 63 to rotate, the number of revolutions of the first ratchet plate 63 is exactly the same as the distance between the two cold heading holes 11. It also includes a first fixed plate 13, which is fixedly connected to multiple unloading rods 12 and the push tube 64 respectively.

[0054] In the embodiment provided by the present invention, it also includes a driving unlocking member, which pushes the clamping feeding member to open when the cold heading head 2 moves. The driving unlocking member includes a first limit plate 51 that is sleeved on the outside of the cold heading head 2, and a plurality of clip plates 52 are slidably arranged in the first limit plate 51. Each clip plate 52 is respectively adapted to each cold heading hole 11, and a rectangular rod 57 is slidably arranged in the clip plate 52. The end of the rectangular rod 57 is fixedly connected to a first wedge plate 58. The two first connecting rods 41 located in the same driving unlocking member are outerly provided with a second limit plate 591, and the second limit plate 591 is fixedly connected to a second wedge plate 59.

[0055] When the first clamping rod 53 is moved to the limiting groove 571, the limiting spring 55 is elastically released, so that the first clamping rod 53 can be moved into the limiting groove 571, so that the clamping plate 52 and the rectangular rod 57 are locked, so that the synchronous movement of the clamping plate 52 and the rectangular rod 57 is realized, and the first wedge plate 58 is driven to move.

[0056] The solution further provided by the present invention also includes an unlocking and resetting member. After the conveying member drives the cold heading workpiece 3 to move, the sliding plate 61 is reset by the unlocking and resetting member. The unlocking and resetting member includes a clamping groove 71 opened on the sliding plate 61, and a second clamping rod 72 adapted to the clamping groove 71 is slidably provided on the cold heading body 1. The top end of the second clamping rod 72 is fixedly connected to a second support plate 73. A limiting hole 79 is provided on the second support plate 73. A third wedge plate 74 is slidably provided in the limiting hole 79. A guide plate 78 adapted to the third wedge plate 74 is fixedly connected to any clamping plate 52.

[0057] In the present invention, the unlocking and resetting member includes a third support plate 75 fixed to the cold heading machine body 1, a second connecting rod 76 is slidably arranged inside the third support plate 75, the second connecting rod 76 is fixedly connected to the third wedge plate 74, and a connecting spring 77 is arranged on the outer sleeve of the second connecting rod 76, and both ends of the connecting spring 77 are respectively fixedly connected to the third support plate 75 and the third wedge plate 74.

[0058] In the present invention, a cold heading process of a cold heading machine for producing environmentally friendly fasteners, using the above-mentioned cold heading machine for producing environmentally friendly fasteners, comprises the following steps:

[0059] S1: Loading: clamping the cold heading workpiece 3 at the cold heading hole 11 by clamping the loading piece;

[0060] S2: Cold heading: The cold heading head 2 is moved to passively open the clamped material and perform cold heading treatment;

[0061] S3: Conveying: After cold heading, the cold heading workpiece 3 is moved to the next cold heading hole 11 by the conveying member;

[0062] S4: unloading. After the conveying member moves, the cold heading head 2 moves to drive the clamped material to open, and then the conveying member is unlocked and reset by unlocking and resetting the reset member.

[0063] When in use, the driving plate 21 is connected to the first fixed plate 13 with a driving device, and the driving device drives the driving plate 21 to move, so that the cold heading head 2 and the first limiting plate 51 move synchronously, and the first limiting plate 51 drives the multiple clamping plates 52 to move synchronously, so that the clamping plates 52 slide on the surface of the rectangular rod 57. When the first clamping rod 53 moves to the limiting groove 571, the clamping rod is driven to move into the limiting groove 571 by the elasticity of the limiting spring 55, so that the clamping plate 52 is connected to the rectangular rod 57. When the clamping plate 52 continues to move, it drives the first wedge plate 58 on the rectangular rod 57 to move synchronously. At this time, the cold heading head 2 pushes the cold heading workpiece 3 into the cold heading hole 11.

[0064] Through the inclined surface of the first wedge plate 58, the double-sided racks 46 are pushed downward when the first wedge moves, so that the sector gear 42 rotates, thereby driving the connecting rod to rotate synchronously, so that the two connecting plates 43 are opened, driving the clamping plate 44 to open, thereby canceling the clamping of the cold heading workpiece 3, and after opening, it does not affect the cold heading head 2;

[0065] After the cold heading is completed, the cold heading head 2 is driven to move out of the cold heading hole 11, and then the rectangular rod 57 is driven to move synchronously, so that the wedge plate moves out of the guide hole 47, and the two clamping plates 44 are pulled closer to each other through the tension of the tension spring 45. When the connecting hole 56 of the first support plate 54 moves to the second wedge plate 59, since the second wedge plate 59 is an inclined surface, the first support plate 54 is pushed to move upward, thereby driving the first clamping rod 53 to move upward and out of the limiting groove 571, so that when the cold heading head 2 continues to move, the clamping plate 52 is driven to slide and reset outside the rectangular rod 57;

[0066] Then, the first fixed plate 13 is driven by the driving device to drive the blanking rod 12 to move and push the cold-forged workpiece 3 out of the cold-forging hole 11. The first fixed plate 13 drives the push tube 64 to move synchronously, and drives the second ratchet plate 66 to move and engage with the first ratchet plate 63 under the elastic force of the clamping spring 67. Then, the push tube 64 continues to move outside the push rod 65, so that the guide block 641 slides in the guide groove 651. When the guide block 641 moves and the guide groove 651 is at the spiral position, the push rod 65 is driven to rotate, so that the second ratchet plate 66 rotates counterclockwise (with a rotation speed of 1 / 400 W). Figure 4 As a reference), since the contact surface between the second ratchet 66 and the first ratchet 63 is wedge-shaped when the second ratchet 66 rotates counterclockwise, the first ratchet 63 is not driven to rotate when the second ratchet 66 rotates, thereby ensuring the stable removal of the cold heading workpiece 3;

[0067] When the driving assembly drives the blanking rod 12 to move outside the cold heading machine body 1, it drives the push tube 64 to move outward, so that the guide block 641 moves synchronously. When the guide block 641 moves to the spiral groove, it drives the push rod 65 to rotate, so that the second ratchet plate 66 rotates clockwise. Since the contact surface between the second ratchet plate 66 and the first ratchet plate 63 is a plane, the rotation of the second ratchet plate 66 drives the first ratchet plate 63 to rotate, thereby driving the gear 68 to rotate synchronously through the driving rod 62, so that the rack 69 drives the sliding plate 61 to move, so that the cold heading workpiece 3 moves to the next cold heading hole 11. At this time, the abutment spring 611 is compressed, and the clamping groove 71 moves to the second clamping rod 72. Through the gravity of the second support plate 73 and the second clamping rod 72, the second clamping rod 72 moves into the clamping groove 71, thereby locking the sliding plate 61.

[0068] When the cold heading head 2 moves for cold heading next time, the clamping plate 52 drives the guide plate 78 to move, so that the guide plate 78 contacts the third wedge plate 74 and pushes the third wedge plate 74 to move, thereby driving the second support plate 73 to move upward, so that the second clamping rod 72 moves out of the clamping groove 71. At this time, the clamping plate 44 opens, and the elastic release of the abutting spring 611 drives the sliding plate 61 to move and reset, so that the clamping plate 44 moves to the previous cold heading hole 11, and then repeats the above operation.

[0069] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
