[0019] The cooling assembly 2 includes a cooling box 23, which is fixedly installed on the upper surface of the workbench 1. The cooling box 23 is used for storing cooling medium and providing a source of cooling liquid for the cooling system. An adding port 22 is formed in the upper surface of the cooling box 23, which facilitates the addition of cooling medium into the cooling box 23. A sealing plug 21 is movably inserted into the inner wall of the adding port 22, which prevents the leakage of cooling medium and ensures the sealing property of the cooling system. A liquid suction pipe 24 is connected to one side of the cooling box 23. One end of the liquid suction pipe 24 is connected to a circulating pump 25, which is fixedly installed on the upper surface of the workbench 1. The liquid suction pipe 24 transports the cooling medium in the cooling box 23 to the circulating pump 25. The circulating pump 25 provides power to make the cooling medium circulate in the cooling system. A first hose 26 is connected to one side of the circulating pump 25. One end of the first hose 26 is connected to a liquid inlet pipe 28. One end of the liquid inlet pipe 28 is connected to a circulating pipe 29. An annular groove 201 is formed in the inside of the lower die 6, which is used in cooperation with the circulating pipe 29. The circulating pipe 29 is fixedly installed in the annular groove 201. The first hose 26 connects the circulating pump 25 and the liquid inlet pipe 28 to transport the cooling medium. The liquid inlet pipe 28 guides the cooling medium into the circulating pipe 29. The circulating pipe 29 is installed in the annular groove 201, which can make the cooling medium evenly surround the inside of the lower die 6, effectively take away the heat generated by the lower die 6 during work, and reduce the temperature of the die.

[0020] One end of the circulation pipe 29 is communicated with a liquid outlet pipe 202, which guides the cooling medium after absorbing heat in the circulation pipe 29, and one end of the liquid outlet pipe 202 is communicated with a second hose 204 connected to the liquid outlet pipe 202 to transport the cooling medium backflow.

The second hose 204 and the outer surface of the liquid outlet pipe 202 are threadedly connected with a second sealing threaded sleeve 203. The first sealing threaded sleeve 27 and the second sealing threaded sleeve 203 are respectively sealed and connected to the connection between the first hose 26 and the liquid inlet pipe 28 and the second hose 204 and the liquid outlet pipe 202 to prevent the cooling medium from leaking and ensure the normal operation of the cooling system. One end of the second hose 204 is communicated with a backflow pipe 205, one end of which is communicated with the cooling box 23. The backflow pipe 205 guides the cooling medium after cooling and circulating through the lower die 6 to the cooling box 23, realizing the recycling of the cooling medium.

[0021] The connecting assembly 3 includes symmetrically distributed insertion rods 38 fixedly installed on the upper surface of the upper die 5. The insertion rods 38 are movably inserted into the mounting sleeve 8. The lower surface of the mounting sleeve 8 is symmetrically provided with insertion grooves 31 matched with the insertion rods 38. The insertion rods 38 are movably inserted into the insertion grooves 31 to preliminarily position the upper die 5 and the mounting sleeve 8, facilitating further fixation. First bolts 37 are threadedly connected between the insertion rods 38 and the mounting sleeve 8 to tightly connect the insertion rods 38 and the mounting sleeve 8, ensuring that the upper die 5 is stably installed on the mounting sleeve 8 during work.

[0022] The upper surface of the workbench 1 is symmetrically fixedly provided with positioning frames 34. The positioning plates 35 are movably clamped in the positioning frames 34. The positioning plates 35 are symmetrically installed on the outer surface of the lower die 6. The clamping cooperation between the positioning frames 34 and the positioning plates 35 can quickly and accurately position the position of the lower die 6 on the workbench 1. The second bolts 36 are threadedly connected between the positioning plates 35 and the upper surface of the workbench 1 to tightly connect the positioning plates 35 and the workbench 1, thereby stably fixing the lower die 6 to prevent displacement during upsetting, ensuring the precision of the forging processing. The upper surface of the positioning plate 35 is provided with a circular groove 33. The anti-slip washers 32 matched with the second bolts 36 are movably clamped in the circular groove 33. The second bolts 36 are movably inserted into the anti-slip washers 32. The anti-slip washers 32 increase the friction between the second bolts 36 and the positioning plates 35 to prevent the second bolts 36 from loosening due to vibration during equipment operation, thereby effectively improving the convenience of using the upsetting equipment.

[0023] Working principle: first, when the device is turned on, the hydraulic cylinder 4 starts to work, the output end of the hydraulic cylinder 4 generates power through the installation sleeve 8 to the upper die 5, so that the upper die 5 has the power basis of downward movement, prepares for the upsetting forging piece.

[0024] The blank to be processed is placed in the lower die 6, and as the output end of the hydraulic cylinder 4 descends, the installation sleeve 8 and the upper die 5 connected thereto are moved downward. The upper die 5 cooperates with the lower die 6 to apply pressure to the blank and perform upsetting operation, so that the blank plastically deforms under the action of pressure and realizes the preliminary forming of the forging piece.

[0025] During the upsetting process, the cooling assembly 2 operates synchronously, and after adding the cooling medium through the liquid inlet 22, it is sealed with the sealing plug 21 to prevent leakage.

[0026] The circulating pump 25 is started, and the cooling medium is extracted from the cooling box 23 through the liquid suction pipe 24. The cooling medium is pressurized by the circulating pump 25, enters the first hose 26, and the first hose 26 is connected to the liquid inlet pipe 28. The cooling medium flows into the circulating pipe 29 through the liquid inlet pipe 28. The cooling medium flows in the circulating pipe 29, uniformly taking away the heat generated by the lower die 6 due to friction with the blank and metal deformation. The cooled cooling medium flows into the second hose 204 through the liquid outlet pipe 202.

[0027] The second hose 204 and the liquid outlet pipe 202 are sealed and connected through the second sealing threaded sleeve 203, and the first hose 26 and the liquid inlet pipe 28 are sealed and connected through the first sealing threaded sleeve 27 to prevent leakage of the cooling medium. The cooling medium flows into the return pipe 205 through the second hose 204, and finally returns to the cooling box 23, completing a cooling cycle and continuously reducing the temperature of the lower die 6 to ensure the service life of the die and the quality of the forging piece.

[0028] When the upper die 5 needs to be replaced, the first bolt 37 between the insertion rod 38 and the installation sleeve 8 is unscrewed through the connecting assembly 3, the insertion rod 38 and the insertion slot 31 are separated, and the upper die 5 can be taken out from the installation sleeve 8. After replacing the new upper die 5, reverse operation is completed.

[0029] When replacing the lower die 6, unscrew the second bolt 36 between the positioning plate 35 and the workbench 1. The positioning plate 35 is positioned in the positioning frame 34, and the anti-skid washer 32 in the circular groove 33 on the upper surface of the positioning plate 35 can prevent the second bolt 36 from loosening. Separate the positioning plate 35 from the positioning frame 34, and the lower die 6 can be removed. The replacement operation of the lower die 6 is convenient and fast to adapt to the processing needs of different sizes of forgings.
