Description

Technical Field

[0001] The utility model relates to the technical field of cold heading dies, in particular to a multi-station cold heading die. Background Art

[0002] The cold heading process is one of the new processes of metal pressure processing with little cutting. It is a processing method that utilizes the plastic deformation of metal under the action of external force, and with the help of a mold, redistributes and transfers the metal volume to form the required parts or blanks. The cold heading die is a mold that cuts, preforms, and forms the blank into a cold-formed part on a cold heading machine. The cold heading process is most suitable for the production of standard fasteners such as bolts, screws, nuts, rivets, and pins. When producing and processing materials, more stamping dies are required, and it is too cumbersome to install them one by one. Therefore, a multi-station cold heading die is used to facilitate the non-stop stamping of materials.

[0003] Prior art includes a utility model with publication number CN219211484U, which discloses a multi-station environmentally friendly CNC cold heading forming mold. The patent adopts a heat transfer block, which is arranged at the bottom of the bottom block of the CNC cold heading forming mold, and the main heat transfer block is fixedly connected to the bottom block of the CNC cold heading forming mold through a slot, and a forming inner block is arranged above the main heat transfer block, and the forming inner block is fixedly connected to the main heat transfer block, and there are more than two forming inner blocks; anti-residue inner pads, which are arranged on both sides of the forming inner block, and the anti-residue inner pads are fixedly connected to the bottom block of the CNC cold heading forming mold through a slot, and a lower fixed heat sink is arranged at the middle position below the main heat transfer block; the utility model equipment solves the problem that the existing equipment requires too much complicated operation by personnel.

[0004] In daily work, when the equipment adjusts the mold before cold heading the material, the equipment mold is generally in an integrated form. When adjusting the process of cold heading materials, the entire mold needs to be replaced, which is too cumbersome and easily wastes the operator's time, resulting in low operator efficiency. Utility Model Content

[0005] The utility model aims to solve the defect that it is difficult to adjust and replace the stations of the multi-station cold heading die separately in the prior art, and proposes a multi-station cold heading die.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a multi-station cold heading die, comprising a mounting rod, a lower die, an upper die, a shaping block and an adjusting device, the upper surface of the mounting rod is provided with a lower die, the upper die is provided above the lower die, the interior of the lower die is provided with a shaping block, the adjusting device is provided inside the lower die, the adjusting device comprises a pulling hole and a limiting groove, the limiting groove is provided on the side of the shaping block, the pulling hole is provided inside the lower die, a pressing groove is provided on the side of the shaping block, a clamping groove is provided inside the lower die, the inner wall of the pressing groove is slidably connected with a clamping ball, one end of the clamping ball is clamped with the inside of the clamping groove.

[0007] Furthermore, one end of the clamping ball is fixedly connected to a first spring, an end of the first spring away from the clamping ball is fixedly connected to the inner wall of the pressing groove, and the inner wall of the pulling hole is slidably connected to a pulling rod. By setting the clamping ball, the forming block can be initially restricted, thereby reducing the risk of the forming block shaking easily when the equipment is in use, making it difficult for the equipment to accurately cold head the material.

[0008] Furthermore, one end of the pull rod is clamped with the inside of the limiting groove, and a retaining ring is fixedly connected to the surface of the pull rod. The pull rod is provided to facilitate limiting the shaping block.

[0009] Furthermore, a second spring is sleeved and connected to the surface of the push rod, and two ends of the second spring are respectively fixedly connected to the surface of the push ring and the inside of the pull hole. The second spring is provided to facilitate the application of binding elastic force to the pull rod.

[0010] Furthermore, a quick-release device is provided inside the lower mold, and the quick-release device includes a limiting groove and a pulling groove. The pulling groove is opened on the side of the lower mold, and the limiting groove is opened on the side of the mounting rod. The inner wall of the pulling groove is slidably connected with a pulling plate, and one end of the pulling plate is fixedly connected with a third spring. The end of the third spring away from the pulling plate is fixedly connected to the inner wall of the pulling groove. By providing the third spring, a reset elastic force can be applied to the pulling plate, thereby reducing the situation in which it is difficult to reset the pulling plate after the pulling plate moves when the equipment is in use.

[0012] Furthermore, a pull handle is fixedly connected to the surface of the pull plate, and the pull handle is provided to facilitate the movement of the pull plate.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the equipment is in use, the user installs the lower mold and the mounting rod, and then installs the upper mold at one end of the gas rod. When the equipment is running, the gas rod drives the upper mold to extrude and mold the material in the middle of the mold. When the equipment is in use, the user pulls the pull rod. When the pull rod moves, it drives the second spring to displace and deform to generate elastic force. Then the pull rod moves out of the limiting groove, and then the shaping block loses its restraint. The shaping block is pulled to drive the card ball to move. When the card ball moves, it drives the first spring to displace and deform to generate elastic force. Then the card ball is out of the card groove. The shaping block loses its restraint and is adjusted. By setting the adjusting device, the shaping block is effectively adjusted to play the role of adjusting the shaping block, which reduces the situation that the equipment is in use. The equipment mold is generally an integrated situation. When adjusting the process of cold heading materials, the overall mold needs to be replaced, which is too cumbersome and easily wastes the operator's time, resulting in low work efficiency of the operator, thereby improving the practicability of the equipment.

[0015] 2. In the utility model, by setting a quick-release device, when the equipment is in use, the user pulls the handle, and then the handle moves, which drives the pull plate to move. When the pull plate moves, it drives the third spring to displace and deform to generate elastic force. When the pull plate moves, it drives the positioning rod to move out of the limit groove. Then the lower mold is freed from restraint. By setting a quick-release device, the equipment can be effectively disassembled quickly, which plays a role in quickly disassembling the lower mold. When the equipment is in use, the equipment is generally installed with bolts, and the use of bolts requires tools to operate. The use of tools is too cumbersome. Long-term use of bolts can easily cause bolt thread slippage, causing the equipment to shake and defective products to appear at the stamping site, thereby improving the practicability of the equipment.

[0023] The specific arrangement and function of the adjusting device 5 and the quick-release device 6 will be described in detail below.

[0024] In this embodiment: the adjusting device 5 is arranged inside the lower mold 2, and the adjusting device 5 includes a pulling hole 51 and a limiting groove 52. The limiting groove 52 is opened on the side of the shaping block 4, and the pulling hole 51 is opened inside the lower mold 2. A pressing groove 54 is opened on the side of the shaping block 4, and a clamping groove 53 is opened inside the lower mold 2. The inner wall of the pressing groove 54 is slidably connected with a clamping ball 55, and one end of the clamping ball 55 is clamped with the inside of the clamping groove 53.

[0025] Specifically, one end of the locking ball 55 is fixedly connected to the first spring 56 , one end of the first spring 56 away from the locking ball 55 is fixedly connected to the inner wall of the pressing groove 54 , and the inner wall of the pulling hole 51 is slidably connected to the pulling rod 57 .

[0026] In this embodiment, by providing the blocking ball 55, the shaping block 4 can be initially restricted, thereby reducing the risk that the shaping block 4 will shake easily when the equipment is in use, making it difficult for the equipment to accurately cold-forge the material.

[0027] Specifically, one end of the pull rod 57 is engaged with the interior of the limiting groove 52 , and a retaining ring 58 is fixedly connected to the surface of the pull rod 57 . The pull rod 57 is provided to facilitate limiting the shaping block 4 .

[0028] Specifically, the surface of the push rod is sleeved with a second spring 59 , and both ends of the second spring 59 are fixedly connected to the surface of the push ring 58 and the inside of the pull hole 51 respectively. The second spring 59 is provided to facilitate the application of binding elastic force to the pull rod 57 .

[0029] In this embodiment: a quick-release device 6 is provided inside the lower mold 2, and the quick-release device 6 includes a limit groove 61 and a pull groove 62. The pull groove 62 is opened on the side of the lower mold 2, and the limit groove 61 is opened on the side of the mounting rod 1. The inner wall of the pull groove 62 is slidably connected with a pull plate 64, and one end of the pull plate 64 is fixedly connected with a third spring 65, and the third spring 65 is fixedly connected to the inner wall of the pull groove 62 at one end away from the pull plate 64.

[0033] Working principle: When the equipment is in use, the user installs the lower mold 2 and the mounting rod 1, and then installs the upper mold 3 at one end of the gas rod. When the equipment is running, the gas rod drives the upper mold 3 to extrude the material in the middle of the mold. When the equipment is in use, the user pulls the pull rod 57. When the pull rod 57 moves, it drives the second spring 59 to displace and deform to generate elastic force. Then the pull rod 57 moves out of the limiting groove 52, and then the shaping block 4 loses its restraint. The shaping block 4 is pulled to drive the card ball 55 to move. When the card ball 55 moves, it drives the first spring 56 to displace and deform to generate elastic force. Then the card ball 55 is out of the card slot 53. The shaping block 4 loses its restraint and is adjusted. By setting the adjustment device 5, the shaping block 4 is effectively adjusted, which plays the role of adjusting the shaping block 4, reducing the equipment in use. The equipment mold is generally an integrated situation. When adjusting the process of cold heading materials, the overall mold needs to be replaced, which is too cumbersome and easy to waste the operator's time, resulting in low work efficiency of the operator, thereby improving the practicability of the equipment.

[0034] When the equipment is in use, the user pulls the handle 66, and the handle 66 moves, which drives the pull plate 64 to move. When the pull plate 64 moves, it drives the third spring 65 to displace and deform to generate elastic force. When the pull plate 64 moves, it drives the positioning rod 63 to move out of the limit groove 61, and then the lower mold 2 is freed from the restraint. By setting the quick-release device 6, the equipment can be effectively disassembled quickly, which plays a role in quickly disassembling the lower mold 2, reducing the equipment in use. The equipment is generally installed with bolts, and the use of bolts requires tools to operate. The use of tools is too cumbersome. Long-term use of bolts can easily cause bolt thread slippage, causing the equipment to shake and defective products to appear at the stamping site, thereby improving the practicability of the equipment.
