Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical manufacturing, specifically relating to a pulley processing punch with a cooling channel. Background Technology
[0002] Pulley punches are key mold components used in mechanical manufacturing for stamping and forming pulleys. They are usually made of high-hardness alloy steel through heat treatment and precision machining. Their design needs to match the parameters such as the tooth profile and groove width of the pulley. The punch applies high pressure to the metal sheet to punch out the wheel groove or tooth structure in one go. It has the characteristics of high efficiency and good consistency, and is widely used in the mass production of pulleys in the fields of automobiles, agricultural machinery, and industrial transmission.
[0003] The current poor heat dissipation of punches leads to a sharp increase in temperature due to frictional heat accumulation during continuous stamping. The punch material softens or anneales at high temperatures, accelerating wear and reducing the sharpness and dimensional accuracy of the cutting edge. Thermal expansion causes abnormal clearance between the punch and the die, resulting in increased burrs or tooth deformation on the pulley. Local overheating may cause micro-cracks or even breakage, shortening the service life of the punch. Utility Model Content

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example
[0028] Reference Figures 1-4 This is an embodiment of the present invention, which provides a pulley machining punch with a cooling channel, comprising:
[0029] The support structure 100 includes a column 110, a ventilation assembly 120 disposed on the outside of the column 110, a mounting assembly 130 disposed on the top of the column 110, and a ventilation connection assembly 140 disposed on the outside of the column 110.
[0030] And, a processing mechanism 200 for stamping.
[0031] The modular design of the punch is achieved by setting a separate structure for the bearing mechanism 100 and the processing mechanism 200, which facilitates maintenance and replacement. The synergistic effect of the ventilation component 120 and the ventilation connection component 140 effectively improves heat dissipation efficiency and reduces the impact of high temperature on the life and processing accuracy of the punch, making it suitable for high-intensity continuous stamping operations.
[0032] Specifically, the ventilation assembly 120 includes a tube 121 fixedly sleeved on the outside of the column 110, and a heat dissipation vertical hole 122 opened on the top of the tube 121. The ventilation assembly 120 also includes a heat dissipation horizontal hole 123 opened on the outside of the tube 121, and a hollow hole 124 opened in the center of the inner cavity of the tube 121.
[0033] The design of the tube body 121 and the vertical heat dissipation hole 122 forms a vertical cooling airflow channel, which accelerates the heat dissipation from the inside of the punch upwards and avoids local overheating. At the same time, the structure is simple and easy to process and manufacture. The addition of the horizontal heat dissipation hole 123 and the hollow hole 124 further optimizes the airflow path, forms a multi-directional heat dissipation network, and enhances the heat exchange capacity. The hollow hole 124 can also reduce the overall weight of the punch and reduce the load on the equipment.
[0034] Furthermore, the horizontal heat dissipation holes 123 and the vertical heat dissipation holes 122 are evenly distributed in a ring array, and the horizontal heat dissipation holes 123 and the vertical heat dissipation holes 122 intersect each other and are interconnected.
[0035] The horizontal heat dissipation holes 123 and the vertical heat dissipation holes 122 distributed in a ring array are interconnected to ensure uniform heat dissipation and avoid local thermal stress concentration. At the same time, the intersecting channels can guide the compressed air to form turbulence and improve heat dissipation efficiency.
[0036] Preferably, the ventilation connection assembly 140 includes a ventilation pipe 141 fixedly installed on the outside of the column 110, a connecting pipe 142 fixedly installed on the end of the ventilation pipe 141, a ventilation channel 143 opened in the inner cavity of the ventilation pipe 141, and a filter cotton block 144 placed in the inner cavity of the ventilation channel 143.
[0037] The ventilation pipe 141 and the connecting pipe 142 facilitate the connection to an external cooling system to achieve active forced heat dissipation; the filter cotton block 144 in the ventilation channel 143 can intercept metal shavings and impurities, prevent blockage of the heat dissipation channel, and ensure long-term stable operation.
[0038] It should be noted that the mounting assembly 130 includes a fixing head 131 fixedly mounted on the top of the column 110, a threaded groove 132 formed on the outside of the fixing head 131, and a threaded head 133 threadedly mounted on the outside of the fixing head 131.
[0039] The threaded connection design of the fixed head 131 and the threaded head 133 allows the punch to be quickly installed or removed, adapting to different punching equipment; the threaded groove 132 enhances the connection stability and avoids loosening caused by high-frequency vibration.
[0040] Furthermore, the processing mechanism 200 includes a tube head 210 fixedly installed at the bottom of the column 110, a chip removal hole 220 annularly opened at the top of the tube head 210, and a punch head 230 fixedly installed at the bottom of the tube head 210.
[0041] The tube head 210 and the chip discharge hole 220 can discharge metal waste generated by stamping in a timely manner, preventing the accumulation of debris from affecting heat dissipation or damaging the stamping head 230; the stamping head 230 is individually fixed with wear-resistant material, which facilitates targeted replacement and reduces maintenance costs.
[0042] During use, the punch head 230 is driven by the punch press to punch and form the metal sheet. The frictional heat generated during the process is conducted to the ventilation component 120 through the column 110. The external cooling system injects compressed air into the ventilation channel 143 through the connecting pipe 142. The medium forms turbulence through the heat dissipation vertical holes 122 and the cross-connected heat dissipation horizontal holes 123, which quickly removes the heat. The hollow hole 124 helps to reduce weight and enhance airflow circulation. At the same time, the chip removal hole 220 promptly discharges the punching waste chips to avoid blocking the heat dissipation path. The filter cotton block 144 intercepts impurities to ensure that the channel is unobstructed. The threaded fixing method of the mounting component 130 ensures that the punch remains stable under high-frequency vibration. The split design allows for quick replacement of the worn punch head 230, realizing efficient continuous operation.
[0043] In summary, the modular assembly and maintenance are achieved through the split design of the load-bearing mechanism 100 and the processing mechanism 200, which significantly improves the efficiency of disassembly and assembly and the service life. The multi-directional heat dissipation network formed by the ventilation component 120 and the ventilation connection component 140, combined with the forced ventilation of the external cooling system, effectively reduces the working temperature of the punch, avoids material softening or deformation caused by high temperature, and ensures processing accuracy.
[0044] The threaded connection structure of the mounting component 130 enhances equipment compatibility and stability, while the chip removal hole 220 and replaceable punch head 230 design of the machining mechanism 200 further optimize the efficiency of chip removal and component replacement.
