The overall idea is as follows: a punch and tip cooling device, including a hydraulic press body 1, a cooling mechanism for easy cooling is used in the hydraulic press body 1, and the cooling mechanism includes a punch conduit 2, a tip conduit 3 and a guide The pipe joint 4, the punch conduit 2 is located on the inner side wall of the hydraulic machine body 1, the pointed conduit 3 is located below the punch conduit 2, the conduit joint 4 is sleeved on the outer side walls of the punch conduit 2 and the pointed conduit 3, the lower end of the hydraulic machine body 1 is fixedly installed with a punch body 11, the lower end of the punch body 11 is fixedly installed with a pointed body 12, the upper end of the hydraulic machine body 1 is also provided with a hydraulic machine air injection hole 13, the upper end of the punch conduit 2 is fixedly installed with a first threaded tube 21, the first threaded tube 21 is threadedly installed on the inner side wall of the hydraulic machine air injection hole 13, when the device is in use, the hydraulic machine air injection hole 13 inside the hydraulic machine is used to inject compressed air. The air will enter the punch conduit 2;

[0025] The inner side wall of the punch guide tube 2 is also provided with an internal thread groove 22, and the circumferential end of the punch guide tube 2 is also provided with at least two inclined grooves 23. The upper end of the pointed guide tube 3 is fixedly installed with a second threaded tube 32, and the circumferential end of the pointed guide tube 3 is also rotatably installed with a nut 31. The second threaded tube 32 is threadedly rotatably installed on the inner side wall of the internal thread groove 22. The gas passes through the punch guide tube 2 and enters the pointed guide tube 3. The gas will take away the heat in the hydraulic press body 1 during transmission.

[0026] The upper end of the catheter connector 4 is also provided with a plug-in guide groove 42, and the inner side wall of the plug-in guide groove 42 is also provided with a tube groove 43. The pointed catheter 3 is plugged into the inner side wall of the tube groove 43, and the diameters of the tube groove 43 and the pointed catheter 3 are matched. The gas will finally pass into the inner cavity of the punch body 11 and the tip body 12 through the cooling mechanism, and the air pressure, flow rate and duration of the air supply for cooling can be adjusted.

[0027] In view of the problems existing in the prior art, the utility model provides a punch and tip cooling device.

The device has a simple structure, can effectively take away heat and discharge it outside the mold, has a good cooling effect, and has a long service life.

[0028] Working principle: When the device is in use, compressed air is injected into the hydraulic press through the hydraulic press air injection hole 13 inside the hydraulic press. The air will enter the punch conduit 2, and the gas will enter the tip conduit 3 through the punch conduit 2. The gas will take away the heat in the hydraulic press body 1 during transmission, and the gas will finally pass through the cooling mechanism into the punch body 11 and the tip body 12. The air pressure, flow rate and duration of air supply for cooling can be adjusted. When the existing hydraulic press is cooled, the hydraulic press is directly cooled by blowing air through the hydraulic press air injection hole 13, and the air flow to the tip body 12 has a relatively small loss. The punch body 11 and the tip body 12 cannot be effectively cooled, the gas flow cannot be effectively controlled, and the punch cannot be fully cooled, thereby affecting product quality, damaging the punch and the tip, and causing an increase in mold cost. The device is equipped with a punch conduit 2, a tip conduit 3 and a conduit connector 4, and its structure is simple. It can effectively take away heat and discharge it outside the mold, has a good cooling effect, and has a long service life. The air pressure, flow rate and duration of air supply used for cooling in the device can be adjusted, so it is convenient to cool down according to actual conditions. The device has a low production cost and is easy to install.
