A rotating groove is opened on the top of the operating table, and a rotating disk is engaged in the rotating groove; the punching mechanism includes a guide plate, a servo motor and a drilling head, the guide plate is installed at the bottom of the hydraulic cylinder through a coupling, a threaded rod is sleeved inside the guide plate, and a drilling head is arranged at the bottom of the threaded rod. There are two drilling heads in total, and the servo motor is installed below the lower mold; the auxiliary mechanism is located above the servo motor, and a fan is arranged on one side of the auxiliary mechanism.

[0003] The above technical solution is fixed to the inner wall of the support frame by setting a fan. The lower mold can be stably rotated on the operating table, which is convenient for adjusting the punching position of the lower mold. The two drilling heads can improve the punching efficiency of the punching machine; the limit plate and the limit rod have a good limiting effect on the lower mold, which is convenient for the stable placement and removal of the lower mold on the top of the rotating disk. The cooling pipe can improve the heat dissipation effect on the bottom of the lower mold. When punching, especially when the hole does not completely penetrate the part, the higher temperature position is mainly concentrated in the upper half of the mold. If this cooling method is used, the efficiency is slightly poor. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a punching machine with a cooling function, which can solve the problem that when the hole does not completely penetrate the part, the position with higher temperature is mainly concentrated in the upper half of the mold, and the part is cooled from the bottom, resulting in poor cooling effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a punching machine with cooling function, comprising a machine body, and parts are arranged on the upper surface of the machine body;

[0006] Wherein, a punching head is installed on the surface of the machine body, and the surface of the punching head can be cooled by the cooling device following the holes;

[0027] See also Figure 1-4 , the utility model provides a technical solution: a punching machine with cooling function, comprising a body 1, and a part 8 is arranged on the upper surface of the body 1;

[0028] The surface of the body 1 is provided with a punching head 7, and the surface of the punching head 7 can be cooled by the cooling device following the holes;

[0029] The cooling device includes a sleeve 13, the interior of the sleeve 13 is rotatably connected to the surface of the punching head 7, a connecting piece 14 is movably sleeved on the surface of the sleeve 13, a connecting rod 18 is welded to the surface of the connecting piece 14, a gasket 9 is welded to the surface of the connecting rod 18, a buffer pad 10 is fixedly bonded to the surface of the gasket 9, and the surface of the buffer pad 10 is in contact with the surface of the part 8;

[0030] The surface of the connecting member 14 is screwed to the spray head 6 , and the lowest point of the spray head 6 is slightly higher than the lowest surface of the punching head 7 .

[0031] A sliding groove 11 is formed on the surface of the sleeve 13 . A limiting column 12 is slidably connected inside the sliding groove 11 . The limiting column 12 is welded to the surface of the connecting piece 14 .

[0032] A baffle 15 is fixedly sleeved on the surface of the punching head 7 , and the upper surface of the baffle 15 contacts the surface of the sleeve 13 .

[0033] A turntable 16 is disposed outside the sleeve 13 , and a threaded member 17 is welded on the surface of the turntable 16 . The threaded member 17 is movably connected to the sleeve 13 via threads, and the surface of the threaded member 17 contacts the surface of the punching head 7 .

[0034] A water tank 4 is screwed onto the surface of the machine body 1 , a water pump 5 is installed at the water outlet of the water tank 4 , and an output end of the water pump 5 is connected to a water inlet end of a sprinkler head 6 via a hose.

[0035] A compressor 3 is screwed onto the surface of the machine body 1 , a condenser 2 is installed at the output end of the compressor 3 , and the condenser 2 runs through the surface of the machine body 1 .

[0036] When punching is required, start the machine body 1 to drive the punching head 7 to move downward to punch its part 8, the downward movement of the punching head 7 drives the sleeve 13 to move downward, the downward movement of the sleeve 13 drives the connecting piece 14 to move downward, the downward movement of the connecting piece 14 drives the spraying head 6 to move downward, the downward movement of the connecting piece 14 drives the connecting rod 18 to move downward, the downward movement of the connecting rod 18 drives the gasket 9 to move downward until the buffer pad 10 contacts the part 8, when the buffer pad 10 contacts the part 8, the connecting piece 14 no longer moves downward, so that the spraying head 6 no longer moves downward, that is, the spraying head 6 remains stationary, and then, start the water pump 5, and the water pump 5 starts to spray the coolant in the water tank 4 through the spraying head 6 to the vicinity of the punching head 7 for cooling.

[0037] At the same time, the compressor 3 is started to circulate its condenser tube 2 to cool down its component 8.

[0038] When it is necessary to adjust the contact position of the buffer pad 10 with the part 8, the turntable 16 is rotated by external force to drive the threaded member 17 to move so that the threaded member 17 no longer presses against the punching head 7, and then the sleeve 13 is rotated to drive the connecting member 14 to rotate and adjust the contact position of the buffer pad 10 with the part 8. After the adjustment is completed, the turntable 16 is rotated to tighten the sleeve 13 and the punching head 7 to fix them.

[0039] By setting a spray head 6 in the cooling device, coolant is sprayed above the holes to assist in cooling. Since the non-penetrating holes are formed from top to bottom, the high temperature is concentrated above the parts. By spraying coolant from top to bottom, the heat dissipation efficiency from top to bottom is more obvious compared to heat dissipation from bottom only.

[0040] Due to the uncertainty of the punching position, there is a phenomenon that the buffer pad 10 cannot contact the parts when moving downward. In order to improve the application scope of the cooling device, a turntable 16 is used to drive the threaded member 17 to loosen the sleeve 13, so that the sleeve 13 can rotate to adjust the position of the buffer pad 10, so that it can better adapt to the contact requirements of different hole positions, thereby expanding the application scope of the cooling device.

[0041] Working principle: when punching is required, start the machine body 1 to drive the punching head 7 to move downward to punch the part 8, the punching head 7 drives the sleeve 13 to move downward, the sleeve 13 drives the connecting piece 14 to move downward, the connecting piece 14 drives the spray head 6 to move downward, the connecting piece 14 drives the connecting rod 18 to move downward, the connecting rod 18 drives the gasket 9 to move downward until the buffer pad 10 contacts the part 8, and then start the water pump 5. The water pump 5 starts to spray the coolant in the water tank 4 through the spray head 6.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
