Its basic principle is to heat the metal material to an appropriate temperature, and then apply pressure to continuously pass it through a shaped die from a specified extrusion barrel. The material is extruded and then cooled to form a billet or part that conforms to the die hole cross-section. During the processing, since the temperature of the metal material just extruded from the equipment is relatively high, a cooling device is required to cool it down accordingly.

A mounting shaft 11 is fixedly installed between the two lifting seats 10, and a base 12 is rotatably installed on the outer wall of the mounting shaft 11. The top of the base 12 is fixedly connected to the bottom of the lifting plate 4. A cooling pool 13 is provided below the plate 4, and the interior of the cooling pool 13 is filled with coolant; when the workpiece moves to the end on the conveyor belt 2, the workpiece will reach the top of the lifting plate 4, and then the lifting motor 5 will drive the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 will drive the retracting roller 8 to rotate, and the rotation of the retracting roller 8 will loosen the connecting belt 9 wrapped around the retracting roller 8, so that the lifting plate 4 is lowered, and the lifting plate 4 is lowered to drive the workpiece to move downward, and the workpiece will enter the coolant in the cooling pool 13 after moving downward, and the workpiece is liquid-cooled by immersing the workpiece in the coolant, thereby improving the cooling effect and cooling efficiency of the device.

[0039] like Figures 1 to 6As shown, the outer wall of the mounting shaft 11 is symmetrically fixed with a support plate 14, the support plate 14 is fitted with the lifting plate 4, the outer wall of the mounting shaft 11 is symmetrically fixed with a positioning plate 15, a telescopic shaft 16 and an elastic member A17 are fixedly installed between the positioning plate 15 and the lifting plate 4, the elastic member A17 is sleeved on the outer side of the telescopic shaft 16, a pressure plate 18 is fixedly installed on one side of the lifting plate 4, a material discharge seat 19 is provided on one side of the cooling pool 13, an inclined plate 20 is fixedly installed on the outer wall of the material discharge seat 19, and the inclined plate 20 is located above the pressure plate 18; when the workpiece completes the liquid cooling work, the lifting motor 5 drives the rotating shaft 7 to reverse, so that the lifting plate 4 drives the workpiece to move up, and when the lifting plate 4 moves up, the pressure plate 18 is fixedly installed on the lifting plate 4. The pressure plate 18 will come into conflict with the inclined plate 20, and the inclined plate 20 will squeeze the pressure plate 18, so that the lifting plate 4 will rotate around the installation axis 11 through the base 12. The rotation of the lifting plate 4 will cause the telescopic axis 16 and the elastic member A17 to contract. After the rotation, the lifting plate 4 is in an inclined state, and the workpiece on the lifting plate 4 will slide onto the inclined plate 20 under the action of gravity and slide along the inclined plate 20 to the inner side of the unloading seat 19 for collection, thereby achieving the effect of automatic unloading. After that, the lifting plate 4 will descend to a position horizontal with the conveyor belt 2. When descending, the lifting plate 4 will be horizontally reset under the action of the elastic force of the elastic member A17 to prepare for the next liquid cooling work, ensuring that the device can continue to perform cooling work.

The outer wall of the limit sliding column 49 is slidably connected to the inner wall of the shaking plate 48. A number of elastic members B50 are fixedly installed between the shaking plate 48 and the lifting plate 4. A push plate 51 is symmetrically fixedly installed on the front of the shaking plate 48. One end of the push plate 51 away from the shaking plate 48 passes through the lifting plate 4 and is fixedly installed with a tooth A52. A vertical plate 53 is symmetrically fixedly installed on the bottom of the inner wall of the cooling pool 13.

A limit baffle 55 is symmetrically fixedly installed on the top of the shaking plate 48. When immersed in the coolant, as the lifting plate 4 descends, the tooth A52 will collide with the tooth B54, and the tooth B54 will squeeze the tooth A52, causing the tooth A52 to move in the direction of the shaking plate 48. When the tooth A52 moves, it will push the shaking plate 48 to move through the push plate 51. When the tooth A52 passes over a tooth B54 each time, the shaking plate 48 will be reset under the action of the elastic part B50.

The vibration of the workpiece can break the bubble layer on the surface of the workpiece, increase the contact area between the coolant and the workpiece, improve the heat exchange efficiency, and make the cooling effect of the workpiece better.

[0042] like Figures 1 to 12 As shown, a support 30 is fixedly installed between the tops of the two side panels 1, a circular plate 31 is fixedly installed on the top of the support 30, a horizontal plate 32 is fixedly installed on the inner wall of the circular plate 31, a rotating motor 33 is arranged on the top of the horizontal plate 32, and the output shaft of the rotating motor 33 is fixedly connected to the fan 3; after starting the rotating motor 33, the rotating motor 33 will drive the fan 3 to rotate, and the rotation of the fan 3 will generate airflow, and when the conveyor belt 2 transports the workpiece, the workpiece will pass under the fan 3, and the airflow generated by the rotation of the fan 3 will blow downward toward the workpiece, thereby achieving the effect of air cooling the workpiece.

[0043] like Figures 1 to 11As shown, a conveying shaft 34 is symmetrically installed for rotation between the inner walls of the two side plates 1, a conveying roller 35 is fixedly installed on the outer wall of the conveying shaft 34, the conveying belt 2 is driven and installed between the two conveying rollers 35, and a plurality of limit strips 36 are evenly and fixedly installed on the outer wall of the conveying belt 2. A conveying motor 42 is arranged on one side of one of the side plates 1, and the output end of the conveying motor 42 is fixedly connected to one end of one of the conveying shafts 34; the conveying motor 42 drives the conveying shaft 34 to rotate, and the conveying shaft 34 drives the conveying roller 35 to rotate, and when the conveying roller 35 rotates, it drives the conveying belt 2 to operate, and the workpiece is placed on the conveying belt 2, and the workpiece is transported by the operation of the conveying belt 2. The setting of the limit strip 36 can provide a fulcrum for the workpiece, and the limit strip 36 provides a fulcrum for the workpiece, so that the workpiece is conveniently sent from the conveying belt 2 to the top of the lifting plate 4.

[0044] like Figures 1 to 5 As shown, limiting columns 37 are symmetrically fixedly installed on the bottom of the inner wall of the cooling pool 13, and limiting members 38 are fixedly installed on the outer walls of the two lifting seats 10, and the inner walls of the two limiting members 38 are slidably connected to the outer walls of the two limiting columns 37 respectively; through the cooperation of the limiting columns 37 and the limiting members 38, the lifting seat 10 is limited, and then the lifting plate 4 is limited, so that the lifting plate 4 moves along a preset direction to prevent the lifting plate 4 from tilting.

[0045] like Figures 1 to 4 As shown, a reinforcement plate A39 is fixedly installed between the bottom of the inner wall of the cooling pool 13 and the inner wall of the limit column 37, a reinforcement plate B40 is fixedly installed between the tops of the two corresponding screws 28, and a reinforcement plate C41 is fixedly installed between the inner walls of the two limit columns 37; the limit columns 37 and the screws 28 are limited by the reinforcement plates A39, B40 and C41 respectively, thereby increasing the stability of the limit columns 37 and the screws 28 and ensuring the stability of the device operation.

[0046] like Figures 1 to 12As shown, a protective seat 43 is fixedly installed on the outer wall of one of the brackets 6, one of the side panels 1 and the top of the cross plate 32, the lifting motor 5, the rotating motor 33 and the conveying motor 42 are respectively fixedly installed on the inner wall of the protective seat 43, the inner wall of the cooling pool 13 is fixedly installed with a drain pipe 44, the inner wall of the drain pipe 44 is threadedly connected with a sealing valve 45, the bottom of the side panel 1 is fixedly installed with a supporting leg 46, the bottom of the supporting leg 46 is fixedly installed with a bottom plate 47, the cooling pool 13 and the unloading seat 19 are fixedly installed on the top of the bottom plate 47; ...

Through the support of the supporting legs 46, the side panel 1 is at a suitable working height to facilitate the use of the device. The device is supported by the bottom plate 47 to increase the contact area between the device and the ground, thereby ensuring the overall stability of the device.

[0047] Working principle: When cooling, the workpiece is placed on the conveyor belt 2, and the conveyor belt 2 is driven to operate by the conveying motor 42. The workpiece is moved by the operation of the conveyor belt 2. The workpiece passes through the inner side of the support 30 when moving, and the fan 3 is driven to rotate by the rotating motor 33. The rotation of the fan 3 generates an airflow blowing toward the workpiece passing from below, thereby cooling the workpiece.

[0048] The workpiece continues to move after being air-cooled. When the workpiece moves to the end of the conveyor belt 2, it moves to the top of the lifting plate 4. Then the lifting motor 5 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives the retracting roller 8 to rotate. The retracting roller 8 lowers the lifting plate 4 through the connecting belt 9. The lowering of the lifting plate 4 causes the workpiece to enter the coolant in the cooling pool 13, thereby liquid-cooling the workpiece. While the lifting plate 4 moves, the lifting seat 10 drives the collar 22 to move through the connecting block 21. When the collar 22 moves, it drives the rotating seat 23 to move. When the rotating seat 23 moves, it rotates by cooperating with the screw 28. When the rotating seat 23 rotates, it drives the stirring plate 26 to rotate. The rotation of 6 can stir the coolant and enhance the cooling effect of the coolant. When the lifting plate 4 is immersed in the coolant, the tooth A52 will conflict with the tooth B54, and the tooth B54 will squeeze the tooth A52, so that the push plate 51 pushes the shaking plate 48 to move. When the tooth A52 passes over a tooth B54, the shaking plate 48 will be reset under the action of the elastic member B50. As the lifting plate 4 moves, the shaking plate 48 will shake back and forth, and the shaking plate 48 will drive the workpiece to vibrate. The vibration of the workpiece can break the bubble layer on the surface of the workpiece, increase the contact area between the coolant and the workpiece, improve the heat exchange efficiency, and further improve the cooling effect of the device.

[0049] After the liquid cooling is completed, the lifting motor 5 drives the lifting plate 4 to move upward. During the upward movement of the lifting plate 4, the pressure plate 18 will come into conflict with the inclined plate 20. After the pressure plate 18 is squeezed, the lifting plate 4 will rotate around the mounting axis 11. After the rotation, the lifting plate 4 is in an inclined state, causing the workpiece to slide down under the action of gravity, thereby achieving the effect of automatic unloading.
