Description

Technical Field

[0001] This utility model relates to the field of cooling equipment design technology, and more specifically, to a cooling structure for a high-speed punch press. Background Technology

[0002] A high-speed punch press is essentially a stamping press. It utilizes a single-piece special cast iron alloy, exhibiting high rigidity and shock resistance. The sliding blocks feature a long guide design and are equipped with a sliding block balancing device to ensure precise and stable operation. It can be integrated with any automated production requirements, effectively improving production efficiency and reducing costs. Currently, under the high-speed stamping action of a high-speed punch press, the upper and lower dies move up and down, generating a large amount of heat through friction. If this heat cannot be reduced in time, it can easily damage the dies, leading to quality problems in the stamped workpieces. Traditional dies are typically cooled by adjusting the room temperature, which prevents the large amount of heat accumulated on the dies from dissipating quickly, resulting in poor cooling performance. Therefore, a cooling structure for high-speed punch presses is proposed. Summary of the Invention

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] The accompanying drawings of the embodiments of this utility model provide a coordinate system XYZ, where the positive direction of the X-axis represents the left and the negative direction of the X-axis represents the right, the positive direction of the Y-axis represents the front and the negative direction of the Y-axis represents the back, the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0028] See Figures 1 to 5 This utility model provides a cooling structure for a high-speed punch press, including a high-power chiller 1 and a cooling assembly mounted on the high-speed punch press. The high-speed punch press has a vertical frame and a vertical support. The vertical support is mounted on the vertical frame, and a punching assembly is located at the front end of the vertical support. The punching assembly includes a punching cylinder and a punching frame 29 connected in sequence. The cooling assembly includes a second chilling assembly located within the punching frame 29. A punch press working end 20 is located at the front end of the vertical frame, and the cooling assembly also includes a first chilling assembly located within the punch press working end 20. The high-power chiller 1 provides chilled water with stable pressure to the first and second chilling assemblies, using the chilled water to spray and exchange heat with the punching frame 29 and the punch press working end 20. To cool the punch press during high-speed operation, this solution uses a high-power chiller 1 to continuously supply chilled water to the first chilled water assembly. This provides heat exchange and cooling to the inner cavity of the punch press working end 20. Then, the chilled water is atomized by the atomizing nozzle 13 and sprayed onto the stamping frame 29, achieving atomized cooling of the stamping frame 29. The stamping frame 29 is equipped with a temperature sensor and signal transmission device, which can transmit the working temperature of the stamping frame 29 to the control terminal in real time. Atomized cooling is suitable when the surface temperature of the punch press assembly does not exceed a critical value. The second chilled water assembly then provides heat exchange to the inner cavity of the stamping frame 29, working in conjunction with the atomizing nozzle 13 to quickly reduce the temperature of the stamping frame 29, ensuring the normal operation of the punch press assembly.

[0029] The vertical support has heat sinks 17 on the side of the stamping assembly. The heat sinks 17 are used to dissipate heat from the stamping assembly, so as to dissipate the heat generated by the high-frequency operation of the stamping assembly and avoid the negative impact of high temperature on the operation of the stamping assembly.

[0030] See Figure 1 and Figure 4The first cooling water assembly includes a first water inlet fixing seat 4 mounted on the working end 20 of the punch press. The first water inlet fixing seat 4 is connected to a first heat exchange tube 8 located inside the working end 20 of the punch press. A first return water pump 9 is provided at the output end of the first heat exchange tube 8, and a first water guide pipe 3 is provided at the input end of the first water inlet fixing seat 4. A first water outlet pump 2 is provided at the high-power chiller 1. The working end 20 of the punch press is fixed to the installation of the first water inlet fixing seat 4 and the second water inlet fixing seat 7. The first water outlet pump 2 inputs cold water from the high-power chiller 1 into the first water guide pipe 3. The cold water in the first water guide pipe 3 is then input into the first heat exchange tube 8 through the first water inlet fixing seat 4. The first heat exchange tube 8 is a spiral-shaped pipe. A connecting frame is provided between the first heat exchange tubes 8 on the working end 20 of the punch press. The cooling and temperature reduction treatment of the main structure of the working end 20 of the punch press is achieved through the heat transfer between the connecting frame and the first heat exchange tube 8.

[0031] A second water inlet fixing seat 7 is provided above the first water inlet fixing seat 4. A second water guide pipe 6 is provided at the input end of the second water inlet fixing seat 7. A second water outlet pump 5 is provided at the high-power chiller 1 in the second water guide pipe 6. An independent water guide pipe 10 is provided at the output end of the second water inlet fixing seat 7. The independent water guide pipe 10 is a U-shaped pipe. Multiple atomizing elements are provided on the independent water guide pipe 10. The second water outlet pump 5 inputs another stream of cold water from the high-power chiller 1 into the second water guide pipe 6. The cold water in the second water guide pipe 6 is then input into the independent water guide pipe 10 through the second water inlet fixing seat 7. The cold water can be connected to each group of atomizing elements through the U-shaped pipe structure of the independent water guide pipe 10, which facilitates direct water supply to each group of atomizing elements, so that the atomizing elements spray atomized water onto the stamping assembly, effectively cooling the stamping assembly when the detection temperature does not exceed the critical value.

[0032] The water flow in the independent water pipe 10 can assist in the heat exchange of the connecting frame. The water flow that has been preheated can achieve its atomization speed faster and improve the atomization efficiency. The independent water pipe 10 and the first heat exchange pipe 8 do not interfere with each other. Therefore, the first heat exchange pipe 8 does not affect the atomizing element. After the cold water has completed its journey in the first heat exchange pipe 8, it flows back to the high-power chiller 1 from the first return water pump 9 and the first return water pipe connected to the first return water pump 9.

[0033] Each atomizing component includes a fixed housing 11, with a torsion frame 12 on the top of the fixed housing 11. Multiple sets of water supply pipes are connected to each set of torsion frames 12 via independent water pipes 10. Each set of water supply pipes has a set of atomizing nozzles 13 on its top. The working end 20 of the punch press is constrained by an extension plane 202 to install each set of fixed housings 11, and the fixed housings 11 constrain the installation of the torsion frames 12. The water supply pipes are designed as malleable tubes that can change shape, allowing the torsion frames 12 to be adjusted to a support state suitable for atomizing spraying. This facilitates the atomizing spraying of the four sets of atomizing nozzles 13 onto the stamping device within the lower panel of the stamping frame 29, removing heat from the stamping device through water mist evaporation and achieving cooling.

[0034] See Figure 2 The second chilled water assembly includes a second heat exchange tube disposed on the edge of the inner cavity of the stamping frame 29. The input end of the second heat exchange tube is provided with a third water inlet fixing seat 15, and the output end of the second heat exchange tube is provided with a second return water pump 16. The second chilled water assembly is configured by placing the second heat exchange tube on the edge of the inner cavity of the stamping frame 29. The chilled water is sent into the third water inlet fixing seat 15 through the water pump and the third water guide pipe. After flowing through the second heat exchange tube once, the chilled water flows back to the high-power chiller 1 from the second return water pump 16 and the second return water pipe for repeated cooling, thereby realizing the reuse of water resources.

[0035] The cooling assembly also includes two sets of spray pipes 28 mounted on a vertical support. The output end of the spray pipes 28 is positioned directly opposite the stamping frame 29. The vertical support is equipped with a water pump and water pipes that control the flow of the two sets of spray pipes 28. A pressure valve is installed inside the spray pipes 28. When the operating temperature of the stamping frame 29 is detected to exceed the critical value, the spray pipes 28 are opened at the control end. After adjusting the water pressure, the water flow is directly sprayed onto the stamping frame 29, which can quickly reduce the temperature of the stamping frame 29. The water that has completed the heat exchange falls directly into the extension plane 202 and flows through the leakage tank 205 to the waste collection cylinder 21, preventing water from flowing out and affecting the production environment, and collecting wastewater for easy reuse.

[0036] An oil storage tank is provided inside the vertical support. The oil storage tank is connected to the first atomizing oil nozzle 18 and the second atomizing oil nozzle 19 through pipes. Lubricating oil is injected into the first atomizing oil nozzle 18 and the second atomizing oil nozzle 19 through pipes. The atomized lubricating oil is sprayed into the inner cavity of the stamping frame 29 by the two sets of oil nozzles to lubricate the connecting and mounting components of the stamping frame 29. The lubricating oil can not only ensure the lubrication of the components, but also assist the cold water to cool down the stamping frame 29.

[0037] See Figure 3 The outer end of the working end 20 of the punch press is provided with an anti-overflow edge 201. The inner side of the anti-overflow edge 201 is provided with an extension plane 202. The inner side of the extension plane 202 is provided with a guide frame 203. The inner side of the guide frame 203 is provided with a working panel 204. The center of the working panel 204 is provided with a lower die frame 206. The outer side of the lower die frame 206 is provided with a drain trough 205. The working area of ​​the stamping frame 29 is much smaller than the specification of the working end 20 of the punch press. The center of the working end 20 of the punch press is set directly opposite the center of the stamping frame 29. The cooling spray waste liquid from the spray pipe 28 to the stamping frame 29 falls onto the extension plane 202. The guide frame 203 guides the waste liquid to the drain trough 205 and the lower die frame 206. Then, the waste liquid is filtered for the first time by the first filter frame 207 to remove impurities. After that, the waste liquid is collected into the waste collection cylinder 21. The anti-overflow edge 201 can prevent the waste liquid from overflowing.

[0038] See Figure 5A waste collection cylinder 21 is provided below the working end 20 of the punch press. A third filter frame 25 is provided inside the waste collection cylinder 21. A second filter frame 23 is provided on top of the third filter frame 25. A return pump 26 is provided at the outer end of the waste collection cylinder 21. The return pump 26 is connected to a high-power chiller 1 through a return pipe 27. A through groove is provided at the top of the waste collection cylinder 21. A first connecting threaded wall is provided on the inner wall of the through groove. A second connecting threaded wall is provided at the outer end of the top of the third filter frame 25. The second connecting threaded wall is screwed onto the first connecting threaded wall, so that the third filter frame 25 is suspended in the waste collection cylinder. Inside the cylinder 21, the second filter frame 23 is placed directly on top of the third filter frame 25. After being filtered by the first filter frame 207, the waste liquid falls into the first water filtration chamber 22. It then undergoes a second round of filtration through the second filter frame 23. The waste liquid after the second round of filtration falls into the second water filtration chamber 24 and then undergoes a final filtration through the third filter frame 25. The waste liquid is then concentrated in the outer cavity of the waste collection cylinder 21. When the waste liquid reaches a certain amount, it is extracted by the return pump 26 and guided back to the high-power chiller 1 through the return pipe 27 for repeated cooling.

[0039] See Figure 1 The high-power chiller 1 is equipped with an upper cooling guide frame 14 on top. The cold water from the third water inlet fixing seat 15 and the spray pipe 28 of the stamping frame 29 is output from the upper cooling guide frame 14. That is, the cold water from the high-power chiller 1 is further cooled by the upper cooling guide frame 14 before being output to the stamping frame 29, which can cool the stamping frame 29 more quickly.

[0040] This utility model provides a cooling structure for a high-speed punch press. A temperature sensor is installed on the punching frame 29 to detect the temperature. The control unit controls the cooling components based on the detection data. When the detected temperature does not exceed a critical value, the atomizing nozzle 13 sprays atomized liquid onto the punching frame 29, allowing the punching frame 29 to evaporate the atomized liquid. This, combined with the second heat exchange tube and lubricating oil, achieves cooling of the punching frame 29. When the detected temperature exceeds the critical value, the spray pipe 28 sprays cold water onto the punching frame 29, rapidly reducing the temperature of the punching frame 29. This, combined with the second heat exchange tube and lubricating oil, achieves cooling of the punching frame 29. During punch press operation, the first heat exchange tube 8, the cooling components installed on the working end 20 of the punch press, and the sprayed waste liquid all cool the working end 20 of the punch press, effectively ensuring the normal operating temperature of the working end 20 of the punch press.

[0041] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
