Description

Technical Field

[0001] This invention relates to the field of vortex forging technology, specifically a vortex forging anti-eccentricity device. Background Technology

[0002] The scroll plate, as the core working component of the scroll compressor, is usually composed of a stationary scroll plate and a moving scroll plate. Its complex involute or modified curve profile and micron-level machining precision are key to achieving efficient gas compression. As the heart of the scroll compressor, the geometric precision, material structure and surface quality of the scroll plate directly determine the compressor's efficiency, noise, vibration and reliability.

[0003] During the forging process, the scroll plate first heats the cylindrical aluminum alloy billet and then transfers it to the forging machine base. Then, the hydraulic press is started to push the die to extrude and forge the billet. In this process, if the operator places the billet manually or the positioning accuracy of the automated system is insufficient, the initial position of the billet in the die cavity is easily deviated from the center. This can lead to insufficient filling on one side of the forging and flash on the other side, resulting in out-of-tolerance dimensions and shape accuracy. In addition, during the long-term forging process, the die needs to be continuously coated with lubricant to ensure the forging quality. This process requires manual operation and is extremely cumbersome, and it is difficult to ensure the uniformity of lubricant application.

[0004] To address this, a vortex disk anti-eccentric forging device is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a vortex disk anti-eccentric forging device to solve the problems in the prior art, such as the operator's manual placement or the insufficient positioning accuracy of the automated system, which easily causes the initial position of the billet in the mold cavity to deviate from the center, and the need to continuously apply lubricant to the mold to ensure forging quality during long-term forging, which requires manual operation and is extremely cumbersome, and it is difficult to ensure that the lubricant is applied evenly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a scroll plate anti-eccentric forging device, the forging device comprising a machine tool, a base, an upper pressure block, an upper die, a positioning component, a lubrication component, and a feeding component; the base is fixedly connected to the machine tool, the upper pressure block is slidably connected to the machine tool via a hydraulic system, the upper die is slidably connected to the upper pressure block, the positioning component is rotatably connected to the base and is cocentric with the base, the lubrication component is disposed inside the upper die and the upper pressure block, the feeding component is fixedly connected to the outside of the upper die and the upper pressure block, the positioning component gradually retracts towards the center of the base after the scroll plate blank is placed on the base, and the lubrication component continuously injects lubricant into the upper die as the upper die moves. The feeding component uses the up-and-down movement of the upper mold to inject lubricant into the lubrication component. During the forging process, after the billet is placed on the base, the positioning component is activated to retract towards the center of the base, thus centering the billet so that its center is at the center of the base. Then, the hydraulic system is activated to drive the upper pressure block and the upper mold to move downward, extruding and forging the billet. During the downward pressing process, the upper mold will first contact the billet. As the upper pressure block continues to press down, it will gradually approach the upper mold until it pushes the upper mold to press the billet into shape. As the upper pressure block approaches and moves away from the upper mold, the lubrication component will automatically inject lubricant into the upper mold, and the feeding component can always maintain sufficient oil in the lubrication component during this process.

[0007] Preferably, the upper pressing block is further provided with a telescopic groove and a receiving groove, and the upper mold is also fixedly connected with a telescopic rod and a return spring; the telescopic rod is slidably connected to the telescopic groove, the return spring is sleeved on the outside of the telescopic rod, the bottom of the return spring is fixedly connected to the upper mold, and the top is fixedly connected to the bottom of the upper pressing block. When the return spring is compressed, it is in the receiving groove; during the downward movement of the upper pressing block, the upper mold will first contact the blank, and then the upper pressing block will continue to descend against the elastic force of the return spring until it contacts the upper mold and pushes the upper mold to extrude and forge the blank. At this time, the return spring will be in the receiving groove.

[0008] Preferably, the positioning assembly includes a drive disk, a drive groove, teeth, a fixing ring, a sliding rod, an arc-shaped push plate, a vertical rod, a support frame, a worm gear, and a drive motor; the drive disk is rotatably connected to the base, the drive groove is equidistantly formed on the drive disk, the teeth are fixedly connected to the periphery of the drive disk, the fixing ring is fixedly connected to the base and is concentric with the base, the sliding rod is slidably connected to the fixing ring, the arc-shaped push plate is fixedly connected to the end of the sliding rod, the vertical rod is fixedly connected to the end of the sliding rod away from the arc-shaped push plate, the support frame is fixedly connected to the base, and the worm gear... The drive motor is rotatably connected to the support frame and fixedly connected to the base. The output shaft of the drive motor is fixedly connected to the worm gear, which meshes with teeth. After the blank is placed on the base, the drive motor can be started. The drive motor will drive the worm gear to rotate, which in turn will drive the drive disc to rotate. The rotating drive disc will drive the upright to gradually move closer to the center of the base through the drive groove. Then, the upright will push the arc-shaped push plate to gradually retract towards the center of the base through the sliding rod, thereby correcting the position of the blank and placing it in the exact center of the base, thus effectively ensuring the accuracy of the scroll forging.

[0009] Preferably, the positioning component further includes a cleaning component; the cleaning component includes a jet head and an outlet; the jet head is fixedly connected above the arc-shaped push plate, the jet head is connected to the air pump through a hose, and multiple sets of outlets are provided, which are equidistantly opened around the fixing ring, and the outlets are aligned with the gaps between two adjacent sets of arc-shaped push plates; the jet heads are all positioned facing the bottom of the arc-shaped push plate directly opposite, making it easier to clean impurities at the angle between the arc-shaped push plate and the base during the jetting process; after the forged vortex disk is removed, the drive motor can be started to rotate back and forth, and at the same time the air pump is turned on to spray high-pressure gas from the jet head. At this time, the jet head, which moves with the arc-shaped push plate, will blow and clean the impurities generated during the forging process on the base. Driven by the high-pressure airflow, the impurities on the base will be discharged to the surroundings along the gaps between the arc-shaped push plates and the outlet.

[0010] Preferably, the lubrication assembly includes a guide channel, a telescopic tube, a liquid inlet, a liquid storage chamber, a bottom slide, and a top slide; the guide channel is located above the vortex groove of the upper mold, and multiple sets of guide channels are provided, arranged equidistantly in a vortex shape along the vortex groove; the telescopic tube is fixedly connected above the guide channel; the liquid inlet is located near the top of the telescopic tube; the liquid storage chamber is located inside the upper pressure block; the bottom slide is located below the liquid storage chamber; the top slide is located above the liquid storage chamber; the telescopic tube is slidably connected to the bottom slide and the top slide; the upper pressure block continues... As the upper die moves downwards and approaches, the telescopic tube extends from the bottom slide and passes through the liquid storage chamber. After the upper pressure block fully contacts the upper die, the top of the telescopic tube will be in the top slide. When the upper pressure block moves upwards after forging, the telescopic tube will pass through the liquid storage chamber from the top channel and into the bottom channel under the pushing action of the return spring. When the telescopic tube passes through the liquid storage chamber, lubricating oil will enter the telescopic tube from the inlet and flow down the telescopic tube into the vortex-shaped mold groove of the upper die, thus playing a lubricating role during the extrusion forging process of the upper die. When the top of the telescopic tube is in the bottom channel, the lubricant will not be able to enter.

[0011] Preferably, the liquid inlet is inclined upwards and outwards from the inside of the telescopic tube, and multiple sets of liquid inlets are provided around the telescopic tube at equal intervals; the inclined arrangement of the liquid inlet allows the telescopic tube to follow the gravity and flow direction of the lubricant as it moves upwards, making it easier for the lubricant to enter the telescopic tube.

[0012] Preferably, the feeding assembly includes a storage tank, a temporary storage chamber, a vertical pipe, an inlet check valve, a horizontal pipe, an outlet check valve, and a piston; the storage tank is fixedly connected to the upper pressure block, the temporary storage chamber is fixedly connected below the storage tank, the vertical pipe connects the storage tank and the temporary storage chamber, the inlet check valve is fixedly connected below the vertical pipe, the horizontal pipe is fixedly connected between the liquid storage chamber and the temporary storage chamber, the outlet check valve is fixedly connected to the horizontal pipe, and the piston is fixedly connected to the upper mold, and the piston is slidably connected to the temporary storage chamber. Next; when forging is completed and the upper die moves away from the upper pressure block, the piston will be pulled downward in the temporary storage chamber by the upper die. At this time, the inlet check valve opens and the outlet check valve is closed. The oil in the storage tank will enter the temporary storage tank through the vertical pipe. During the forging process, when the upper die approaches the upper pressure block, the piston will be pushed upward in the temporary storage chamber by the upper die. At this time, the inlet check valve closes and the outlet check valve opens. The lubricant will be pushed by the piston and enter the liquid storage chamber from the horizontal pipe to fill the lubricant in the liquid storage chamber.

[0013] Preferably, the piston component includes a plunger, a sliding groove, a sliding column, a base, and a push spring; the plunger is slidably connected to the temporary storage cavity, the sliding groove is formed at the bottom of the plunger, the sliding column is slidably connected to the sliding groove, the base is fixedly connected below the sliding column, and the push spring is sleeved on the outside of the sliding column, with its bottom fixedly connected to the base and its top fixedly connected to the plunger; when the upper mold approaches the upper pressure block, the upper mold will drive the base to push the plunger into the temporary storage cavity using the push spring. When the lubricant in the storage cavity is sufficient, the plunger will be unable to push the lubricant. The lubricant flows into the storage chamber, and the bottom support will overcome the spring force of the push spring to push the sliding column into the sliding groove. When the lubricant in the storage chamber is insufficient, the bottom support will push the plunger into the temporary storage chamber through the push spring during the rising process, thereby pushing the lubricant into the storage chamber to replenish it. At the same time, in this state, the telescopic tube passing through the storage chamber will be pushed by the plunger to push the lubricant, and the lubricant will more easily enter the telescopic tube from the inlet. When the upper mold is away from the upper pressure block, the bottom support will pull the plunger downward through the push spring, thereby drawing the lubricant in the storage box into the temporary storage chamber.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after the blank is placed on the base, the drive motor can be started. The drive disc will then drive the upright to gradually approach the center of the base through the drive groove. The upright will push the arc-shaped push plate to gradually retract towards the center of the base through the sliding rod, thereby correcting the position of the blank and placing it in the exact center of the base. This effectively ensures the precision of the vortex forging. After the forged vortex is removed, the drive motor can be started to rotate back and forth, and at the same time, the air pump can be turned on to spray high-pressure gas from the jet nozzle. At this time, the jet nozzle, which moves with the arc-shaped push plate, will blow away the impurities generated during the forging process on the base. Blown by the high-pressure airflow, the impurities on the base will be discharged to the surroundings through the gaps between the arc-shaped push plates and the outlet, thereby achieving a clean and tidy finish.

[0015] 2. In this invention, after the upper die comes into contact with the blank, as the upper pressure block continues to move downwards and approaches the upper die, the telescopic tube will extend from the bottom slide and pass through the liquid storage cavity. After the upper pressure block and the upper die are fully in contact, the top of the telescopic tube will be in the top slide. When the upper pressure block moves upwards after forging is completed, under the pushing action of the return spring, the telescopic tube will pass through the liquid storage cavity from the top channel and be in the bottom channel. When the telescopic tube passes through the liquid storage cavity, the lubricating oil will enter the telescopic tube from the inlet and flow down the telescopic tube to the vortex-shaped mold groove of the upper die, and then be extruded and forged by the upper die.

[0016] 3. In this invention, when the upper mold approaches the upper pressure block, the upper mold will drive the bottom support to push the plunger into the temporary storage cavity using the push spring. When the lubricant in the storage cavity is sufficient, the plunger will not be able to push the lubricant into the storage cavity. As a result, the bottom support will overcome the elasticity of the push spring and push the sliding column into the sliding groove. When the lubricant in the storage cavity is insufficient, the bottom support will push the plunger into the temporary storage cavity through the push spring during the rising process, thereby pushing the lubricant into the storage cavity to replenish it. At the same time, in this state, the telescopic tube passing through the storage cavity will be pushed by the plunger to push the lubricant, and the lubricant will more easily enter the telescopic tube from the inlet.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 8 This invention provides a vortex disk anti-eccentric forging device, the technical solution of which is as follows: Reference Figure 1 A scroll plate anti-eccentric forging device is disclosed. The forging device includes a machine tool 1, a base 2, an upper pressure block 3, an upper die 4, a positioning component 5, a lubrication component 6, and a feeding component 7. The base 2 is fixedly connected to the machine tool 1. The upper pressure block 3 is slidably connected to the machine tool 1 via a hydraulic system. The upper die 4 is slidably connected to the upper pressure block 3. The positioning component 5 is rotatably connected to the base 2 and is centered on the base 2. The lubrication component 6 is disposed inside the upper die 4 and the upper pressure block 3. The feeding component 7 is fixedly connected to the outside of the upper die 4 and the upper pressure block 3. After the scroll plate blank is placed on the base 2, the positioning component 5 gradually retracts towards the center of the base 2. The lubrication component 6 continuously injects lubricant into the upper die 4 as the upper die 4 moves. The feeding component 7 utilizes the vertical movement of the upper die 4... The power source injects lubricant into the lubrication component 6. During the forging process, after the billet is placed on the base 2, the positioning component 5 is activated to retract towards the center of the base 2, thus centering the billet so that its center is at the center of the base 2. Then, the hydraulic system is activated to drive the upper pressure block 3 and the upper mold 4 to move downwards, extruding and forging the billet. During the downward pressing process, the upper mold 4 will first contact the billet. As the upper pressure block 3 continues to press down, it will gradually approach the upper mold 4 until it pushes the upper mold 4 to press the billet into shape. During the process of the upper pressure block 3 approaching and moving away from the upper mold 4, the lubrication component 6 will automatically inject lubricant into the upper mold 4, and the feeding component 7 can always keep the oil in the lubrication component 6 sufficient during this process.

[0021] Reference Figure 4 and Figure 6The upper pressure block 3 is also provided with a telescopic groove 31 and a receiving groove 32. The upper mold 4 is also fixedly connected with a telescopic rod 41 and a return spring 42. The telescopic rod 41 is slidably connected to the telescopic groove 31. The return spring 42 is sleeved on the telescopic rod 41. The bottom of the return spring 42 is fixedly connected to the upper mold 4, and the top is fixedly connected to the bottom of the upper pressure block 3. When the return spring 42 is compressed, it is in the receiving groove 32. The upper mold 4 is slidably connected to the upper pressure block 3 through the telescopic rod 41. During the downward movement of the upper pressure block 3, the upper mold 4 will first contact the blank. Then the upper pressure block 3 will continue to overcome the elastic force of the return spring 42 and descend until it contacts the upper mold 4 and pushes the upper mold 4 to extrude and forge the blank. At this time, the return spring 42 will be in the receiving groove 32. Then the bottom surface of the upper pressure block 3 can completely contact the top surface of the upper mold 4 and push the upper mold 4 down.

[0022] Reference Figure 2 The positioning component 5 includes a drive disk 51, a drive groove 52, teeth 53, a fixing ring 54, a sliding rod 55, an arc-shaped push plate 56, a vertical rod 57, a support frame 58, a worm gear 59, and a drive motor 510. The drive disk 51 is rotatably connected to the base 2. The drive groove 52 is equidistantly opened on the drive disk 51. The teeth 53 are fixedly connected to the periphery of the drive disk 51. The fixing ring 54 is fixedly connected to the base 2 and is at the same center as the base 2. The sliding rod 55 is slidably connected to the fixing ring 54. The arc-shaped push plate 56 is fixedly connected to the end of the sliding rod 55. The vertical rod 57 is fixedly connected to the end of the sliding rod 55 away from the arc-shaped push plate 56. The support frame 58 is fixedly connected to the base 2. The worm gear 59 is rotatably connected to the support frame 58. The drive motor 510 is fixedly connected to the base 2. The output shaft of motor 510 is fixedly connected to worm gear 59, and worm gear 59 meshes with teeth 53. After the blank is placed on base 2, drive motor 510 can be started. Drive motor 510 will drive worm gear 59 to rotate, and worm gear 59 will drive drive disk 51 to rotate. The rotating drive disk 51 will drive upright rod 57 to gradually approach the center of base 2 through drive groove 52. Then upright rod 57 will push arc-shaped push plate 56 to gradually retract towards the center of base 2 through sliding rod 55, thereby correcting the position of blank and making blank in the exact center of base 2, thus effectively ensuring the accuracy of scroll forging. After the blank is centered, drive motor 510 will rotate in the opposite direction, driving arc-shaped push plate 56 to move outward away from blank. At this time, upper mold 4 can be started to forge blank.

[0023] Reference Figure 2 and Figure 3The positioning component 5 also includes a cleaning component 511; the cleaning component 511 includes a jet head 5111 and an outlet 5112; the jet head 5111 is fixedly connected above the arc-shaped push plate 56, and the jet head 5111 is connected to the air pump through a hose; multiple sets of outlets 5112 are provided, and the multiple sets of outlets 5112 are equidistantly opened around the fixing ring 54, and the outlets 5112 are aligned with the gaps between the two adjacent sets of arc-shaped push plates 56; wherein the jet heads 5111 are all set facing the bottom of the arc-shaped push plate 56 directly opposite, making it easier to clean the arc-shaped push plate 56 during the jetting process. Impurities at the angle between the base 6 and the base 2 are cleaned; after the forged vortex disk is removed, the drive motor 510 can be started to rotate back and forth, and at the same time the air pump is turned on to spray high-pressure gas from the jet head 5111. At this time, the jet head 5111, which moves with the arc-shaped push plate 56, will spray and clean the impurities generated during the forging process on the base 2. Under the blowing of the high-pressure airflow, the impurities on the base 2 will be discharged to the surroundings along the gap between the arc-shaped push plates 56 and the outlet 5112, thereby achieving the purpose of cleanliness and preventing impurities from affecting the quality of forging.

[0024] Reference Figures 4 to 7 The lubrication assembly 6 includes a guide channel 61, a telescopic tube 62, a liquid inlet 63, a liquid storage cavity 64, a bottom slide 65, and a top slide 66. The guide channel 61 is located above the vortex groove of the upper mold 4. Multiple sets of guide channels 61 are arranged equidistantly in a vortex shape along the vortex groove. The telescopic tube 62 is fixedly connected above the guide channel 61. The liquid inlet 63 is located near the top of the telescopic tube 62. The liquid storage cavity 64 is located inside the upper pressure block 3. The bottom slide 65 is located below the liquid storage cavity 64, and the top slide 66 is located above the liquid storage cavity 64. The telescopic tube 62 is slidably connected to the bottom slide 65 and the top slide 66. After the upper mold 4 contacts the blank, the upper pressure block... As the upper die 4 continues to move downwards, the telescopic tube 62 will extend from the bottom slide 65 and pass through the liquid storage chamber 64. After the upper pressure block 3 fully contacts the upper die 4, the top of the telescopic tube 62 will be in the top slide 66. When the upper pressure block 3 moves upwards after forging is completed, under the pushing action of the return spring 42, the telescopic tube 62 will pass through the liquid storage chamber 64 from the top channel and be in the bottom channel. When the telescopic tube 62 passes through the liquid storage chamber 64, the lubricating oil will enter the telescopic tube 62 from the inlet 63 and flow down the telescopic tube 62 into the vortex-shaped mold groove of the upper die 4, thus playing a lubricating role during the extrusion forging process of the upper die 4. When the top of the telescopic tube 62 is in the bottom channel, the lubricant will not be able to enter.

[0025] Reference Figure 6 and Figure 7The liquid inlet 63 is opened from the inside of the telescopic tube 62 outward and upward at an angle, and multiple sets of liquid inlets 63 are set around the telescopic tube 62 at equal intervals. The inclined setting of the liquid inlet 63 allows the telescopic tube 62 to follow the gravity and flow direction of the lubricant during the upward movement of the telescopic tube 62, making it easier for the lubricant to enter the telescopic tube 62.

[0026] Reference Figure 8 The feeding assembly 7 includes a storage tank 71, a temporary storage chamber 72, a vertical pipe 73, an inlet check valve 74, a horizontal pipe 75, an outlet check valve 76, and a piston 77. The storage tank 71 is fixedly connected to the upper pressure block 3, the temporary storage chamber 72 is fixedly connected below the storage tank 71, the vertical pipe 73 is connected between the storage tank 71 and the temporary storage chamber 72, the inlet check valve 74 is fixedly connected below the vertical pipe 73, the horizontal pipe 75 is fixedly connected between the liquid storage chamber 64 and the temporary storage chamber 72, the outlet check valve 76 is fixedly connected to the horizontal pipe 75, and the piston 77 is fixedly connected to the upper mold and slidably connected to the temporary storage chamber 72. When forging is complete and the upper die 4 moves away from the upper pressure block 3, the piston 77 will be pulled by the upper die 4 and move downward in the temporary storage chamber 72. At this time, the inlet check valve 74 opens and the outlet check valve 76 closes. The oil in the storage tank 71 will enter the temporary storage tank through the vertical pipe 73. During the forging process, when the upper die 4 approaches the upper pressure block 3, the piston 77 will be pushed by the upper die 4 and move upward in the temporary storage chamber 72. At this time, the inlet check valve 74 closes and the outlet check valve 76 opens. The lubricant will be pushed by the piston and enter the liquid storage chamber 64 from the horizontal pipe 75 to fill the lubricant in the liquid storage chamber 64.

[0027] Reference Figure 8The piston component 77 includes a plunger 771, a sliding groove 772, a sliding column 773, a base 774, and a push spring 775. The plunger 771 is slidably connected to the temporary storage cavity 72. The sliding groove 772 is formed at the bottom of the plunger 771. The sliding column 773 is slidably connected to the sliding groove 772. The base 774 is fixedly connected below the sliding column 773. The push spring 775 is sleeved on the outside of the sliding column 773. The bottom of the push spring 775 is fixedly connected to the base 774, and the top is fixedly connected to the plunger 771. When the upper mold 4 approaches the upper pressure block 3, the upper mold 4 will drive the base 774 to push the plunger 771 into the temporary storage cavity 72 using the push spring 775. When the lubricant in the liquid storage cavity 64 is sufficient, the plunger 771 will not be able to be pushed. Lubricant flows into the reservoir 64, and the base 774 will overcome the spring force of the push spring 775 to push the sliding column 773 into the sliding groove 772. When the lubricant in the reservoir 64 is insufficient, the base 774 will push the plunger 771 into the temporary storage chamber 72 through the push spring 775 during the rising process, thereby pushing the lubricant into the reservoir 64 to replenish it. At the same time, in this state, the telescopic tube 62 passing through the reservoir 64 will be pushed by the plunger 771 to push the lubricant, and the lubricant will more easily enter the telescopic tube 62 from the inlet 63. When the upper mold 4 is away from the upper pressure block 3, the base 774 will pull the plunger 771 downward through the push spring 775, thereby drawing the lubricant in the storage box 71 into the temporary storage chamber 72.

[0028] The working principle of this invention is as follows: During the forging process, after the billet is placed on the base 2, the drive motor 510 can be started. The drive motor 510 will drive the worm gear 59 to rotate, and the worm gear 59 will drive the drive disk 51 to rotate. The rotating drive disk 51 will drive the upright rod 57 to gradually move closer to the center of the base 2 through the drive groove 52. Then, the upright rod 57 will push the arc-shaped push plate 56 to gradually retract towards the center of the base 2 through the sliding rod 55, thereby correcting the position of the billet and placing the billet in the exact center of the base 2. This effectively ensures the accuracy of the vortex forging. After the billet is centered, the drive motor 510 will rotate in the opposite direction, driving the arc-shaped push plate 56 to move outward away from the billet. At this time, the upper mold 4 can be started to forge the billet. After forging is completed and the vortex disk is removed, the drive motor 510 can be started to rotate back and forth, and at the same time the air pump is turned on to spray high-pressure gas from the jet head 5111. At this time, the jet head 5111, which moves with the arc-shaped push plate 56, will spray and clean the impurities generated during the forging process on the base 2. Under the blowing of the high-pressure airflow, the impurities on the base 2 will be discharged to the surroundings along the gap between the arc-shaped push plates 56 and the outlet 5112, thereby achieving the purpose of cleanliness and preventing impurities from affecting the quality of forging. During the forging process, after the upper die 4 contacts the billet, as the upper pressure block 3 continues to move downwards and approaches the upper die 4, the telescopic tube 62 extends from the bottom slide 65 and passes through the liquid storage cavity 64. After the upper pressure block 3 and the upper die 4 are fully in contact, the top of the telescopic tube 62 will be in the top slide 66. When the forging is completed and the upper pressure block 3 moves upwards, under the pushing action of the return spring 42, the telescopic tube 62 will again pass from the top channel through the liquid storage cavity 64 and be in the bottom channel. When the telescopic tube 62 passes through the liquid storage cavity 64, the lubricating oil will enter the telescopic tube 62 from the inlet 63 and flow down the telescopic tube 62 into the vortex-shaped mold groove of the upper die 4, thus playing a lubricating role during the forging process of the upper die 4. When the top of the telescopic tube 62 is in the bottom channel, the lubricant will not be able to enter. As the upper mold 4 approaches the upper pressure block 3, the upper mold 4 will drive the bottom support 774 to push the plunger 771 into the temporary storage cavity 72 using the push spring 775. When the lubricant in the liquid storage cavity 64 is sufficient, the plunger 771 will be unable to push the lubricant into the liquid storage cavity 64, and the bottom support 774 will overcome the elasticity of the push spring 775 to push the sliding column 773 into the sliding groove 772. When the lubricant in the liquid storage cavity 64 is insufficient, the bottom support 774 will push the plunger 771 into the temporary storage cavity 772 through the push spring 775 during the rising process. The upper mold 4 moves within the upper pressure block 3, thereby pushing the lubricant to flow into the storage chamber 64 for replenishment. At the same time, in this state, the telescopic tube 62 passing through the storage chamber 64 will be pushed by the plunger 771 to push the lubricant, and the lubricant will more easily enter the telescopic tube 62 from the inlet 63. When the upper mold 4 moves away from the upper pressure block 3, the bottom support 774 will pull the plunger 771 downward through the push spring 775. At this time, the discharge check valve 76 is in the closed state and the inlet check valve 74 is in the open state, thereby drawing the lubricant in the storage box 71 into the temporary storage chamber 72.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
