Description

Technical Field

[0001] The utility model relates to the technical field of forging dies, in particular to a punching die used for round steel forging. Background Art

[0002] As we all know, when forging round steel, it is sometimes necessary to pre-process through holes on the round steel. The usual practice is to first put the round steel to be punched on a hollow tube with a through hole, and then use a hot press to forge and punch. The punch of the hot press reciprocates on the surface of the round steel until a through hole is punched on the round steel.

[0003] The existing punching dies for round steel forging need to be manually clamped and fixed. Manual clamping often relies on the operator's experience and skill level, and it is difficult to ensure the accuracy and consistency of each clamping. This may cause the round steel to deviate or shake during the punching process, causing the punching position to deviate from the predetermined position, thereby reducing the punching accuracy, which not only affects the punching accuracy and product quality but also reduces work efficiency.

[0008] In order to store the connecting plate, the utility model is improved in that the rectangular groove is extended to the vicinity of the opening to form a guide groove, and the connecting plate is located in the guide groove.

[0009] In order to store the clamping plate, the utility model is improved in that a storage groove is opened just above the guide groove, and the clamping plate is located in the storage groove.

[0010] In order to clamp round steels with different inner diameters, the utility model is improved in that the clamping groove is designed in a V shape.

[0011] In order to limit the position of the sliding block, the utility model is improved in that a limiting block is installed in the middle of the rectangular groove.

[0012] In order to facilitate the control of the operating state of the driving motor, the utility model is improved in that two groups of control buttons are respectively installed on one side wall of the placement seat, and the control buttons and the driving motor are electrically connected.

[0013] In order to ensure the stability and accuracy of the operation of the driving motor, the utility model is improved in that the driving motor is a servo motor.

[0014] Preferably, the utility model is improved in that the side walls of the clamping groove are provided with anti-slip grooves.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a punching die for round steel forging, which has the following beneficial effects:

[0017] The punching die for round steel forging, through the provided clamping and fixing device, drives the motor to drive the bidirectional screw, so that the slider drives the clamping plate to clamp and fix the two ends of the round steel, which can greatly reduce the shaking or movement of the round steel during the punching process, thereby improving the stability of the punching operation. The stable processing environment is helpful to reduce errors and improve product quality. The clamping and fixing device can shorten the clamping time of the round steel, thereby improving production efficiency.

[0018] The punching die for round steel forging has a V-shaped clamping groove, which can adapt to round steels with different inner diameters. The V-shaped clamping groove can evenly distribute the clamping force, making the round steel more stable when subjected to force, which helps to improve the accuracy and consistency of punching. The symmetry and slope design of the V-shaped clamping groove help to ensure the center positioning of the round steel during the clamping process. No matter how big the inner diameter of the round steel is, it can be automatically centered as long as it is placed in the clamping groove, thereby simplifying the positioning and clamping process and improving work efficiency.

In the present embodiment, when in use, the placement seat 2 is first installed on the workbench 1, and then the hollow tube 3 is installed into the mounting groove 5 on the placement seat 2 through the mounting seat 4, and one end of the round steel to be punched is inserted into the hollow tube 3, and then the driving motor 12 is started. The output end of the driving motor 12 drives the bidirectional screw 7 to rotate. Due to the limitation of the rectangular groove 13, the bidirectional screw 7 drives the slider 8 to move linearly in the rectangular groove 13 during the rotation process, and the slider 8 drives the connecting plate 9, and the connecting plate 9 drives the clamping plate 10, so that the clamping plate 10 moves from both ends toward the middle, that is, the direction of the round steel, until the clamping groove 11 contacts the side wall of the round steel, and the round steel sleeved on the hollow tube 3 is clamped and fixed. When the round steel needs to be rotated, the driving motor 12 is started to reverse, so that the clamping device releases the clamping and fixing of the round steel, and the round steel can be rotated to adjust the position of the next punching. The design of the two sets of clamping plates 10 can fix the left and right ends of the round steel to ensure the stability of the round steel during the later punching process.

[0026] During actual use, the connecting plate 9 is further stored. In this embodiment, the rectangular groove 13 extends to the vicinity of the opening 6 and a guide groove 14 is provided. The connecting plate 9 is located in the guide groove 14. When punching the round steel, the guide groove 14 is convenient for storing the connecting plate 9, and the guide groove 14 can also guide the connecting plate 9 to ensure the stable linear movement of the slider 8.

[0027] During actual use, the clamping plate 10 is further stored. In this embodiment, a storage groove 15 is opened just above the guide groove 14, and the clamping plate 10 is located in the storage groove 15. When punching the round steel, the storage groove 15 is convenient for storing the clamping plate 10.

[0028] In actual use, round steels with different inner diameters are further clamped. In this embodiment, the clamping groove 11 is of V-shaped design. The design of the V-shaped groove allows the clamping groove 11 to flexibly adapt to round steels with different inner diameters. Due to its open V-shaped structure, it can easily accommodate round steels of various sizes without the need for frequent replacement of clamps.

[0029] In actual use, the slider 8 is further limited. In this embodiment, a limit block 16 is installed in the middle of the rectangular groove 13. The limit block 16 limits the slider 8 to prevent the two groups of sliders 8 from directly contacting each other.

[0030] In actual use, it is further convenient to control the operating status of the drive motor 12. In this embodiment, two groups of control buttons 17 are respectively installed on the side walls of the placement seat 2. The control buttons 17 and the drive motor 12 are electrically connected. The two groups of control buttons 17 are convenient for controlling the forward and reverse rotation of the drive motor 12, and for controlling the clamping and release of the clamping device.

[0031] In actual use, the stability and accuracy of the operation of the drive motor 12 are further guaranteed. In this embodiment, the drive motor 12 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid stalling, vibration and other problems, thereby ensuring the stability and accuracy of the operation of the drive motor 12.

[0032] Preferably, in this embodiment, the side walls of the clamping groove 11 are provided with anti-slip grooves. The design of the anti-slip grooves can increase the friction coefficient between the side walls of the clamping groove 11 and the round steel, so that the round steel is more firmly fixed in the clamping groove 11, and the slippage caused by vibration or external force is reduced, thereby improving the stability of clamping.

[0033] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings.
