[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a hexagonal bolt blank cold stamping equipment, including: a workbench 1 and a water tank 15, the top of the workbench 1 is fixedly connected with a lower die 5, the lower die 5 is provided with a cooling channel 19, the input end of the cooling channel 19 is fixedly connected with a first water inlet pipe 11, the output end of the cooling channel 19 is fixedly connected with a first water outlet pipe 12, both sides of the outer surface of the lower die 5 are provided with heat dissipation fins 4, a condenser 10 is provided between the outer surfaces of the two heat dissipation fins 4, one end of the condenser 10 is fixedly connected with a second water outlet pipe 13, the other end of the condenser 10 is fixedly connected with a second water inlet pipe 14, and the inner surface of the water tank 15 is provided with a water pump 18. The output end of the water pump 18 is fixedly connected to a connecting block 17, a semiconductor refrigeration plate 16 is provided on the rear surface of the water tank 15, the bottom of the first water outlet pipe 12 is fixedly connected to the top of the water tank 15, the bottom of the second water outlet pipe 13 is fixedly connected to the bottom of the water tank 15, the bottom of the first water outlet pipe 12 is fixedly penetrated and extended to the inside of the top of the water tank 15, the bottom of the second water outlet pipe 13 is fixedly penetrated and extended to the inside of the top of the water tank 15, the bottoms of the first water outlet pipe 12 and the second water outlet pipe 13 are both fixedly connected to the top of the connecting block 17, a controller 2 is fixedly connected to the top of the workbench 1 near the front side, and a temperature sensor 3 is provided on the front surface of the lower mold 5.

[0023] The effect achieved by the entire embodiment 1 is that the temperature sensor 3, the semiconductor refrigeration plate 16 and the water pump 18 are all electrically connected to the controller 2. When the bolt blank is cold stamped through the lower die 5, the temperature of the lower die 5 can be detected in real time through the temperature sensor 3. When the temperature exceeds the set threshold, a signal is transmitted to the controller 2, and the controller 2 receives and processes it to start the water pump 18, so that the coolant in the water tank 15 is pumped into the connecting block 17 through the water pump 18, and then enters the first water inlet pipe 11 and the second water inlet pipe 14 at the same time, and then cooled. The liquid enters the cooling channel 19 through the first water inlet pipe 11, and then the coolant flows in the cooling channel 19, and then flows into the first water outlet pipe 12 through its output end to form a cycle, so that the coolant circulates in the cooling channel 19. When the coolant flows in the cooling channel 19, it absorbs the heat in the lower mold 5 and dissipates the heat of the lower mold 5. At the same time, when the coolant enters the second water inlet pipe 14, the coolant enters the condenser 10 along the second water inlet pipe 14, and then flows therein, and finally discharged into the water tank 1 through the second water outlet pipe 13. 5, so that the coolant circulates in the condenser 10, and the surface area of ​​the lower mold 5 can be increased through the heat dissipation fins 4 on both sides, and the heat dissipation area is increased. At the same time, the coolant will circulate in the heat dissipation fins 4 along the condenser 10, take away the heat on the heat dissipation fins 4, and further dissipate heat for the lower mold 5. By dissipating heat to the inside and outside of the lower mold 5 at the same time, heat can be quickly and effectively extracted from the lower mold 5, and the heat dissipation effect of the lower mold 5 can be accelerated, which can effectively reduce the temperature of the surface of the lower mold 5, reduce friction and thermal expansion, extend the service life of the mold, and improve the quality of the product. At the same time, in the process of dissipating heat for the lower mold 5, because the cooling end of the semiconductor refrigeration plate 16 is in contact with the outer wall of the water tank 15, the cooling end of the semiconductor refrigeration plate 16 absorbs the heat of the coolant in the water tank 15, resulting in a decrease in the temperature of the cold side, so that the heat dissipation of water can be achieved. At the same time, the heating end of the semiconductor refrigeration plate 16 absorbs heat and releases the heat to the external environment through heat dissipation to keep the cooling end of the semiconductor refrigeration plate 16 working normally. By dissipating the coolant, the heat dissipation effect of the lower mold 5 is guaranteed.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a support frame 6 is fixedly connected to the top of the workbench 1 near the rear side, a hydraulic rod 9 is fixedly connected to the top of the support frame 6, a driving end of the hydraulic rod 9 is movably penetrated through the top of the support frame 6, an upper mold 7 is fixedly connected to the driving end of the hydraulic rod 9, a guide rod 8 is symmetrically and movably penetrated through the top of the support frame 6, and the bottom ends of the two guide rods 8 are fixedly connected to the top of the upper mold 7.

[0025] The effect achieved by the entire embodiment 2 is that the blank is placed inside the lower die 5, and then the hydraulic rod 9 is started to move its driving end downward, driving the upper die 7 to move downward, and then the blank is cold stamped with the cooperation of the upper die 7 and the lower die 5. At the same time, when the upper die 7 moves downward, the two guide rods 8 will move along the support frame 6, thereby limiting the moving path of the upper die 7, which can ensure that the movement path of the upper die 7 during the cold stamping process is accurate, thereby ensuring the consistency of the cold stamping position and shape of the blank, and improving the processing accuracy and quality of the product.

[0026] Working principle: the blank is placed inside the lower die 5, and then the hydraulic rod 9 is started to move its driving end downward, driving the upper die 7 to move downward, and then the blank is cold stamped with the cooperation of the upper die 7 and the lower die 5. The temperature of the lower die 5 can be detected in real time by the temperature sensor 3. When the temperature exceeds the set threshold, a signal will be transmitted to the controller 2, and the controller 2 receives and processes it to start the water pump 18, so that the coolant in the water tank 15 is pumped into the connecting block 17 through the water pump 18, and then enters the first water inlet pipe 11 and the second water inlet pipe 14 at the same time, and then the coolant enters the cooling channel 19 through the first water inlet pipe 11, and then the coolant flows in the cooling channel 19, and then flows into the first water outlet pipe 12 through its output end, forming a cycle, so that the coolant circulates in the cooling channel 19. When the coolant is in the cooling channel 19, When the coolant flows in the lower mold 5, it will absorb the heat in the lower mold 5 and dissipate the heat of the lower mold 5. At the same time, after the coolant enters the second water inlet pipe 14, the coolant will enter the condenser 10 along the second water inlet pipe 14, and then flow therein, and finally be discharged into the water tank 15 through the second water outlet pipe 13, so that the coolant circulates in the condenser 10. At the same time, the heat dissipation fins 4 on both sides can increase the surface area of ​​the lower mold 5 and increase the heat dissipation area. At the same time, the coolant will circulate in the heat dissipation fins 4 along the condenser 10, take away the heat on the heat dissipation fins 4, and further dissipate the heat of the lower mold 5. By dissipating the heat inside and outside of the lower mold 5 at the same time, the heat can be quickly and effectively extracted from the lower mold 5, the heat dissipation effect of the lower mold 5 can be accelerated, the temperature of the surface of the lower mold 5 can be effectively reduced, friction and thermal expansion can be reduced, the service life of the mold can be extended, and the quality of the product can be improved.
