Description

Technical Field

[0001] The utility model relates to the technical field of cooling components, and particularly relates to a cooling structure for a forging punch. Background Art

[0002] The punch of a forging machine refers to a metal part installed on a stamping die, also known as a punch rod, punch needle or punch, slider. It is an important component in stamping processing. Its main function is to directly contact the material to cause the material to undergo deformation, cutting or punching and other processing processes.

[0003] During operation, the punch will generate heat due to friction with the material and its own mechanical movement. If these heats are not effectively cooled, the following potential hazards may occur:

[0004] Overheating and deformation of the punch: High temperature will cause thermal expansion of the punch material. Working at high temperature for a long time, the punch may deform due to uneven thermal stress. The deformed punch will directly affect the processing accuracy and product quality, and may even cause the punch to be damaged or scrapped.

[0005] Deterioration of material processing quality: Overheating of the punch may also cause the surface temperature in contact with the material to be too high, thus affecting the processing performance of the material. For example, at high temperature, the mechanical properties such as hardness and strength of the material may change, resulting in the processed product not meeting the requirements.

[0006] Equipment failures and safety hazards: Overheating of the punch may also trigger other equipment failures, such as overheating of bearings and failure of lubricating oil. In addition, if the punch suddenly breaks or flies out due to overheating, it may cause personal injury to the operator.

[0007] Reduction of production efficiency: To avoid the damage caused by overheating of the punch, it may be necessary to frequently stop the machine for cooling, which will directly affect the production efficiency.

[0008] The inventor found the following problems in the prior art that have not been well solved during the implementation of this solution: However, most of the cooling mechanisms of traditional forging punches are installed inside the equipment. But when the machine works for a long time, it is very easy for impurities, oil stains or water scales that may be contained in the cooling medium to accumulate inside the cooling device after long-term use, resulting in blockage. The blockage will affect the flow of the cooling medium, reduce the cooling effect, and even cause the cooling device to fail; or the seals of the cooling device are aged, damaged or improperly installed, etc., which may all cause leakage. The leakage will not only reduce the cooling effect, but may also cause corrosion or damage to the equipment, and at the same time will waste the cooling medium;

[0009] But when the cooling mechanism needs to be repaired, it is necessary to stop the forging machine, then disassemble the machine, and remove the cooling mechanism from its interior before it can be repaired. This method seriously affects the work progress. Summary of the Invention

[0010] The main object of the present utility model is to provide a cooling structure for a forging punch, which can effectively solve the problems in the background art.

[0011] To achieve the above object, the technical solution adopted by the present utility model is as follows:

[0012] The cooling structure of the forging punch includes a sleeve. A plurality of spraying cavities are formed in the inner wall of the sleeve. A spraying cavity is formed inside each spraying cavity. A flange seat is fixed to the outer wall of the sleeve above the plurality of spraying cavities. A water inlet hole is formed at the top end of each spraying cavity. A joint one is connected to the outer wall of the sleeve at the position of the water inlet hole. A water distribution pipe is sleeved outside the sleeve between the joints one. The water distribution pipe is respectively connected and communicated with the joint one. Both ends of the water distribution pipe are connected with a water inlet pipe. A gas guiding cavity is formed on the side of each spraying cavity away from the spraying cavity. A gas guiding box is fixed to the outer part of the sleeve at the position of the gas guiding cavity. A gas distribution pipe is connected to the side of each gas guiding box away from the sleeve. A main gas pipe is sleeved outside between the gas distribution pipes. Both top ends of the main gas pipe are connected with an air inlet pipe. A water outlet hole is formed on the side of the bottom end inside each spraying cavity away from the spraying cavity. A joint two is connected to the outer side of the sleeve at the position of the water outlet hole. A collecting pipe is sleeved outside between the joints two. Both bottom ends of the collecting pipe are connected with a discharge pipe.

[0013] Preferably, the gas distribution pipes are respectively connected and communicated with the main gas pipe.

[0014] Preferably, the joint one is respectively communicated with the water inlet hole.

[0015] Preferably, the joint two is respectively communicated with the water outlet hole.

[0016] Preferably, the side of each spraying cavity away from the spraying cavity is in an outward expanding shape.

[0017] Preferably, one end of each spraying cavity close to the water outlet hole is in an inward contracting shape.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] 1. Cooling water enters several spray cavities through the water inlet pipe, water distribution pipe, joint one, and water inlet holes. High-pressure gas enters the spray cavities through the air inlet pipe, main air pipe, branch air pipe, air guide box, and air guide cavity, and can spray the water dripping in the spray cavities through the spray cavity. The sleeve is installed at the position where the punch extends through the flange seat and bolts. When the punch extends from the machine, water will be sprayed onto the outer wall of the punch to achieve the effect of cooling and cooling it. Moreover, this application is installed at the outer end of the machine. When disassembly is required, the device can be disassembled as long as the punch is controlled not to extend, without shutting down and disassembling the forging machine, which has good practicability.

[0020] 2. Some remaining cooling water that has not been sprayed can be discharged from the discharge pipe through the water outlet holes at the bottom of the spray cavity, joint two, and collection pipe, avoiding water seepage and waste caused by accumulation in the spray cavity. The collected cooling water can be reused to achieve better practical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figures 1-4As shown in the figure, the cooling structure of the forging punch includes a sleeve 1. A number of ejection chambers 4 are drilled on the inner wall of the sleeve 1, and spray chambers 3 are drilled inside each ejection chamber 4. A flange seat 17 is fixed on the outer wall of the sleeve 1 above the several spray chambers 3. Water inlet holes 2 are drilled at the top ends of the spray chambers 3. Joints 10 are connected to the outer walls of the sleeve 1 at the positions of the water inlet holes 2. A water distribution pipe 11 is sleeved outside the sleeve 1 between the joints 10. The water distribution pipe 11 is respectively connected and communicated with the joints 10. Both ends of the water distribution pipe 11 are connected with water inlet pipes 12. Air guide chambers 5 are drilled on the sides of the spray chambers 3 far away from the ejection chambers 4. Air guide boxes 6 are fixed outside the sleeve 1 at the positions of the air guide chambers 5. Branch air pipes 7 are connected to the sides of the air guide boxes 6 far away from the sleeve 1. A main air pipe 8 is sleeved outside between the branch air pipes 7. Inlet air pipes 9 are connected to both top ends of the main air pipe 8. Water outlet holes 13 are drilled at the bottom ends of the spray chambers 3 on the sides far away from the ejection chambers 4. Joints 14 are connected to the outer sides of the sleeve 1 at the positions of the water outlet holes 13. A collecting pipe 15 is sleeved outside between the joints 14. Drain pipes 16 are connected to both bottom ends of the collecting pipe 15.

[0028] Specifically, the branch air pipes 7 are respectively connected and communicated with the main air pipe 8, the joints 10 are respectively communicated with the water inlet holes 2, and the joints 14 are respectively communicated with the water outlet holes 13.

[0029] Specifically, the sides of the ejection chambers 4 far away from the spray chambers 3 are all in an outward-expanded shape, so that the gas can expand the spraying area when spraying the falling cooling water.

[0030] Specifically, the ends of the ejection chambers 4 close to the water outlet holes 13 are all in an inward-received shape, so that the remaining cooling water will not seep out towards the position of the punch, but enters the collecting pipe 15 through the water outlet holes 13 and the joints 14.

[0031] Working principle: The cooling water enters the several spray chambers 3 after passing through the water inlet pipes 12, the water distribution pipe 11, the joints 10 and the water inlet holes 2. The high-pressure gas enters the spray chambers 3 after passing through the inlet air pipes 9, the main air pipe 8, the branch air pipes 7, the air guide boxes 6 and the air guide chambers 5, and can spray the water falling in the spray chambers 3 through the ejection chambers 4. The sleeve 1 is installed at the position where the punch extends out by matching the flange seat 17 with bolts. When the punch extends out from the machine, the water will be sprayed onto the outer wall of the punch to achieve the effect of cooling. And this application is installed at the outer end of the machine. When disassembly is required, only need to control the punch not to extend and then disassemble this device, without stopping and disassembling the forging machine, which has good practicability. Some of the remaining cooling water that has not been sprayed can be discharged from the drain pipes 16 through the water outlet holes 13, the joints 14 and the collecting pipe 15 at the bottom of the spray chambers 3, avoiding the situation of water seepage and waste caused by accumulation in the spray chambers 3. The collected cooling water can be reused to achieve a better practical effect.
