Description

Technical Field

[0001] This invention relates to the field of axle processing technology, and in particular to an automatic axle straightening and stamping equipment and process. Background Technology

[0002] In the traditional production process of axles, stamping requires transferring the axle to a specialized stamping machine. By creating a groove on the inner wall of the axle straightening block to accommodate the stamping box, the axle surface can be stamped after straightening without transferring the axle. This simplifies the axle processing flow and steps, and improves the efficiency of axle processing.

[0003] However, traditional methods of manually limiting the stamp box from the outside using connecting rods or using other mechanical equipment for assisted gripping are difficult to adapt to the movement trajectory of the straightening equipment. Simple flexible limiting structures cannot provide good support during the transfer of stamp boxes, and simple rigid limiting structures are affected by impact forces from different directions, affecting the strength and stability of the local structure. Summary of the Invention

A control device connected to the stamping device is also mounted on the upper end of the straightening base. The control device includes a position control device and a limiting component mounted on the upper end of the position control device. The limiting component has a rigid state and a non-rigid state. After the position control device pushes the stamping device into the receiving groove, it controls the limiting component to be in a non-rigid state to complete the stamping of the axle surface.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] After the axle is straightened, a steel stamp number needs to be marked on the surface of the axle to mark and distinguish axles of different types and production times.

[0031] In the traditional axle production process, stamping requires transferring the axle to a specialized stamping machine. By creating a groove on the inner wall of the axle straightening block to accommodate the stamping box, the axle surface can be stamped after straightening without transferring the axle, simplifying the axle processing flow and improving efficiency. However, traditional methods of manually limiting the stamping box from the outside using a connecting rod or using other mechanical equipment for assisted holding are difficult to adapt to the movement trajectory of the straightening equipment. Simple flexible limiting structures cannot provide good support during the transfer of the stamping box, and simple rigid limiting structures are affected by impact forces from different directions, impacting the strength and stability of the local structure.

[0032] To solve the above problems, please refer to the appendix. Figure 1 -Appendix Figure 10 An automatic axle straightening and stamping device includes a straightening base 100, with multiple straightening blocks 110 for straightening axles 200 mounted on the upper end of the straightening base 100, and a stamping device 300. The inner sidewall of each straightening block 110 has a receiving groove for accommodating the stamping device 300. A control device 400 connected to the stamping device 300 is also mounted on the upper end of the straightening base 100. The control device 400 controls the stamping device 300 to enter the receiving groove. The stamping device 300 can move towards the axle 200 along with the straightening blocks 110 to stamp the surface of the axle 200. During the axle straightening process, the stamping device 300 is controlled to move out of the receiving groove. At this time, the stamping device 300 will not move synchronously with the straightening blocks 110, thus not affecting the normal straightening process of the axle 200.

[0033] Specifically, the control device 400 includes a position control device 410 and a limiting component 420 installed on the upper end of the position control device 410. The limiting component 420 has a rigid state and a non-rigid state. After the position control device 410 pushes the stamping device 300 into the receiving groove, it controls the limiting component 420 to be in a non-rigid state to complete the stamping of the axle 200 surface. At this time, the stamping device 300 can move synchronously with the straightening block 110 to complete the stamping operation on the axle 200 surface. During the stamping process, the stamping device 300 is in a non-rigid state. In a rigid state, the impact generated by the straightening block 110 will not affect the limiting component 420, ensuring the normal and continuous use of the overall structure. During the process of removing the stamping device 300, the limiting component 420 is kept in a rigid state, which allows the stamping device 300 to be removed normally and placed in the rated position for standby. This ensures that the stamping device 300 can correctly enter the receiving groove next time, and the overall structure can remain stable during the impact, without affecting the straightening of the axle 200.

[0034] In summary, through the above structural design, the state of the limiting component 420 can be adjusted according to the state of the stamping device 300, ensuring the stability of the stamping device 300 during the stamping process, while the straightening block 110 will not impact the structure of the outer control device 400, thus ensuring the service life of the overall structure; at the same time, after the stamping is completed, the limiting component 420 is in a rigid state and can remain stable in the rated position, allowing the stamping device 300 to accurately enter the receiving groove for further processing.

[0035] A locking component 430 is provided on the inner wall of the receiving groove. After the stamping device 300 reaches the predetermined position, the locking component 430 is controlled to be locked. By setting the locking component 430, the stability of the stamping device 300 in the receiving groove can be guaranteed. When the limiting component 420 is in a flexible state, the locking component 430 limits and fixes the stamping device 300, preventing the stamping device 300 from leaving the receiving groove and ensuring the stability of the stamping device 300 during the stamping process.

[0036] Specifically, the locking assembly 430 includes a first locking telescopic rod 431 and a second locking telescopic rod 432. The first locking telescopic rod 431 is located at the end of the moving path of the stamping device 300, and the extension direction of the second locking telescopic rod 432 intersects the moving path of the stamping device 300. The first locking telescopic rod 431 and the second locking telescopic rod 432 are connected through a delivery pipe with a built-in control valve. During the process of the stamping device 300 moving inward, the stamping device 300 can squeeze the first locking telescopic rod 431, and the control oil in the first locking telescopic rod 431 enters the second locking telescopic rod 432. The extended second locking telescopic rod 432 can clamp and limit the stamping device 300 from both sides, ensuring the stability of the stamping device 300 in the receiving groove and ensuring the stability of the stamping device 300 during the stamping process.

[0037] During the movement of the stamping device 300, the control valve is in the open state, which allows the control oil in the first locking telescopic rod 431 to be squeezed into the second locking telescopic rod 432 to complete the clamping and limiting. At the same time, after the stamping device 300 moves to the predetermined position, the control valve is closed. At this time, the second locking telescopic rod 432 can stably clamp and limit the stamping device 300, preventing the stamping device 300 from disengaging. In addition, through the above structural design, the position of the stamping device 300 can be positioned. Applying a predetermined force to push the stamping device 300 can complete the positioning and clamping of the stamping device 300. Compared with the traditional locking structure, this limiting structure is simple and reliable, and meets the requirements for stamping on the surface of the axle.

[0038] Please refer to the appendix for details. Figure 8The stamping device 300 here includes multiple stamp blocks 340 and a receiving box 310 for accommodating the multiple stamp blocks 340. A connecting workpiece 330 is fixed to the first side wall of the receiving box 310 and connected to the control device 400. The outer surface of the stamp blocks 340 has specific numbers. By arranging multiple stamp blocks 340, different codes can be completed. By setting the connecting workpiece 330, the stamping device 300 can be installed and positioned from the outside, so that the stamping device 300 can be inserted into the predetermined position in the receiving groove, ensuring the normal stamping of the axle 200 surface.

[0039] A locking block 320 extending outward is fixed to the second side wall of the receiving box 310. The cross-section of the receiving groove is T-shaped and adapted to the locking block 320. By setting the locking block 320, the overall structure of the stamping device 300 can be further limited, ensuring the stability of the overall structure. The size of the receiving groove is designed to match the locking block 320, which can guide the overall structure of the stamping device 300, allowing the overall structure of the stamping device 300 to accurately enter the receiving groove, ensuring the accuracy of the positioning of the stamping device 300. At the same time, when the straightening block 110 deflects inward, the locking block 320 is pressed against the upper end of the inner wall of the receiving groove during the inward tilting process, further preventing the stamping device 300 from moving out of the receiving groove and ensuring the stability of the stamping device 300 during the stamping process.

[0040] Specifically, the position control device 410 includes an electric guide rail 411 and an electric slider 412. An elastic air pump assembly 500 is provided on the moving path of the electric slider 412. The surface of the stamping device 300 is provided with an air outlet that communicates with the air pump assembly 500. During the linear movement of the electric slider 412 controlled by the electric guide rail 411, the air pump assembly 500 can be squeezed. After being squeezed, the air pump assembly 500 can discharge the internal gas. The gas is discharged from the air outlet on the surface of the stamping device 300, which can clean the surface of the stamping device 300 and prevent the accumulation of oxides from the high-temperature axle 200 on the surface of the stamping device 300, thus ensuring the normal operation of the stamping device 300 for subsequent stamping.

[0041] The vent is preferably located at the top and extends downwards to exhaust gas. The gas acts directly on the surface of the stamped block 340. The oxides are subjected to the combined effects of gravity and gas force, which can clean the surface of the stamped block 340 from top to bottom, thus minimizing the residue of oxides on the surface of the stamped block 340.

[0042] Specifically, the air pumping assembly 500 includes a limiting plate 510, and an elastic pumping air bag 520 is installed between the limiting plate 510 and the electric slider 412. The pumping air bag 520 is connected to two pumping pipes with built-in one-way valves. The first pumping pipe is connected to the air outlet. During the return stroke of the limiting sleeve 421 (moving the stamping device 300 out of the receiving groove), the air pumping assembly 500 can be squeezed to realize the blowing process. During the process of the limiting sleeve 421 controlling the stamping device 300 to move towards the receiving groove, the air pumping assembly 500 resets under its own elastic force and can return to the inflated state. During this process, it can draw in external gas to prepare for the next air pumping.

[0043] Through the above structural design, the overall pumping method is simple and reliable, requiring no manual intervention. During the movement of the stamping device 300 driven by the limiting sleeve 421, the blowing and suction operations are automatically completed, improving the efficiency of oxide removal.

[0044] Please refer to the appendix for details. Figure 6 Specifically, the limiting component 420 includes a limiting sleeve 421, with a limiting telescopic rod 422 installed on the inner wall of the limiting sleeve 421. The telescopic end 4222 of the limiting telescopic rod 422 is connected to the stamping device 300, and the base end 4221 of the limiting telescopic rod 422 is connected to the inner wall of the limiting sleeve 421. The two can be connected by a universal joint. An adjusting component is installed on the inner wall of the limiting sleeve 421 to control the rigid and non-rigid states. When the stamping device 300 is stamping, the straightening block 110 drives the stamping device 300 to stamp. The axle moves outward along an arc-shaped trajectory. During this process, the limiting telescopic rod 422 extends and deflects at a predetermined angle, and the stamping device 300 moves synchronously to stamp the surface of the axle 200. During the reset process, the limiting telescopic rod 422 resets along the opposite trajectory. At this time, the limiting telescopic rod 422 returns to its initial state, and the control adjustment component is in a rigid state. This allows for the limiting and fixing of the limiting telescopic rod 422 and the outer stamping device 300, ensuring that they are in a rigid and stable state.

[0045] The adjustment assembly here includes multiple deformable adjustment parts 4211, which are arranged circumferentially around the limiting telescopic rod 422. The adjustment parts 4211 have rigid and non-rigid states. When the limiting telescopic rod 422 is in a rigid state, it can be limited and fixed from multiple directions. When the limiting telescopic rod 422 is in a non-rigid state, it can move freely. Through the above structural design, the limiting telescopic rod 422 can be stably supported while having sufficient free movement space to meet the control requirements.

[0046] The adjusting unit 4211 here can be a hydraulic telescopic rod of an external pumping device. By controlling the hydraulic telescopic rod to be in a high-pressure state, the limiting telescopic rod 422 can be controlled to be in a rigid state. By controlling the hydraulic telescopic rod to be in a low-pressure state, the limiting telescopic rod 422 can be controlled to be in a non-rigid state. Similarly, the adjusting unit 4211 can be a limiting bladder with built-in electrorheological fluid. By controlling the electrorheological fluid to be in a conductive solid state, the limiting telescopic rod 422 can be controlled to be in a rigid state. By controlling the electrorheological fluid to be in a non-conductive liquid state, the limiting telescopic rod 422 can be controlled to be in a non-rigid state, thus meeting the requirements of structural switching control.

[0047] An automatic axle straightening and stamping process, using the aforementioned automatic axle straightening and stamping equipment, includes the following steps:

[0048] S1. Place the axle 200 between multiple straightening blocks 110 and straighten the axle 200 through the straightening blocks 110. The axle 200 is straightened under high temperature. During the straightening process, the axle 200 is continuously controlled to rotate around the axis, so that the axle can be straightened from different directions.

[0049] S2. The control limit component 420 is in a rigid state, and the stamping device 300 is pushed into the receiving groove by the position control device 410. By controlling the limit component 420 to be in a rigid state, the stamping device 300 can enter the receiving groove stably and accurately to complete the subsequent stamping operation.

[0050] S3. When the control limit component 420 is in a non-rigid state, the stamping device 300 moves synchronously with the straightening block 110 to complete the stamping on the surface of the axle 200. In this state, the stamping device 300 can move synchronously with the control device 400 to complete the stamping marking work on the surface of the axle 200.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
