Description

Technical Field

[0001] The invention relates to the field of cold forging, and more specifically, to an aluminum alloy plate cold forging equipment. Background Art

[0002] Cold die forging is a general term for plastic processing such as cold extrusion and cold heading. Cold forging is a forming process below the recrystallization temperature of the material and is forging performed below the recovery temperature. In production, forging without heating the blank is usually called cold forging. Cold forging materials are mostly aluminum and some alloys, copper and some alloys, low carbon steel, medium carbon steel, and low alloy structural steel with low deformation resistance and good plasticity at room temperature. Cold forgings have good surface quality and high dimensional accuracy and can replace some cutting processes. Cold forging can strengthen metals and improve the strength of parts.

[0003] The cold forging process is also composed of three elements: materials, molds, and equipment. The only difference is that the materials in stamping are mainly plates, while the materials in cold forging are mainly discs or wires.

[0004] During the cold forging process, due to the huge pressure generated between the aluminum alloy plate and the mold, friction occurs between the aluminum alloy plate and the mold. In order to reduce friction, it is usually necessary to apply lubricating oil to the surface of the mold and the punch block to reduce the friction between the tool and the workpiece, reduce the force required during the forging process, thereby reducing equipment wear and extending the service life of the tool. The commonly used oiling method is mainly through manual application, which will cause the worker's arm to be in the cold forging area, posing a great safety hazard. Summary of the invention

[0024] See also Figures 1 to 10 A cold forging processing equipment for aluminum alloy plates includes a base 1, a stamping component is arranged on the rear side of the upper surface of the base 1, a fixed die 9 is fixedly connected to the upper surface of the base 1, side plates 4 are fixedly connected to the two sides of the upper surface of the base 1, a sliding rod 8 is fixedly connected to the front side of the side plate 4, a sliding sleeve 7 is sleeved on the outer surface of the sliding rod 8, a movable die 10 is fixedly connected to one side of the sliding sleeve 7, a groove 13 is opened inside the movable die 10, a molding groove 14 is opened in the middle of the bottom of the groove 13, a lubrication component 5 for adding lubricating oil is arranged on the inner surface of the molding groove 14, and a positioning component 6 for positioning the aluminum alloy plate is arranged at the bottom of the groove 13.

[0025] like Figure 3 - Figure 6As shown, the lubrication assembly 5 includes an annular frame 51 slidably arranged on the inner surface of the molding groove 14, an oil storage groove 59 opened on the upper surface of the movable mold 10, and an L-shaped plate 58 fixed to the rear side of the upper surface of the punching block 12. The inner surface of the annular frame 51 is provided with a plurality of oil outlet holes 53, and the outer surface of the annular frame 51 is provided with an annular groove 511 near the top. A piston 55 is slidably connected to the inside of the oil storage groove 59, and the top of the piston 55 is fixedly connected to a T-shaped plate 54. The first springs 52 are fixedly connected to both sides of the lower surface of the T-shaped plate 54, and an oil inlet pipe 510 is provided at the bottom of the oil storage groove 59.

[0026] The stamping component includes a support frame 2 fixed on one side of the upper surface of the base 1, a hydraulic push rod 11 is fixedly connected to the lower surface of the support frame 2, the output end of the hydraulic push rod 11 is fixedly connected to the stamping block 12, an electric push rod 3 is fixedly connected to the rear side of the support frame 2, one side of the oil inlet pipe 510 passes through the annular groove 511 and extends to the interior of the annular frame 51, the bottom of the first spring 52 is fixedly connected to the upper surface of the movable mold 10, the output end of the electric push rod 3 is fixedly connected to one side of the movable mold 10, rotating components 56 are arranged on both sides inside the movable mold 10, and an oil collecting component 57 is arranged inside the fixed mold 9.

[0027] Before cold forging, it is necessary to apply lubricating oil to the surface of the mold. Therefore, during cold forging, the piston 55 is pulled out, a certain amount of lubricating oil is added to the inside of the oil storage tank 59, and then the piston 55 is inserted into the inside of the oil storage tank 59. When the hydraulic push rod 11 drives the punching block 12 to move into the movable mold 10, the punching block 12 also drives the L-shaped plate 58 to move downward. The L-shaped plate 58 moves downward to press the T-shaped plate 54 downward, and at the same time compresses the two first springs 52. The T-shaped plate 54 drives the piston 55 to slide inside the oil storage tank 59, and the lubricating oil inside the oil storage tank 59 is squeezed into the inside of the annular frame 51 through the oil inlet pipe 510. The lubricating oil enters the The lubricating oil enters the interior of the annular frame 51 and then flows out through the oil outlet hole 53. The lubricating oil flows along the interior of the forming groove 14 to lubricate the surface of the forming groove 14. When the punching block 12 moves upward, the elastic force of the two first springs 52 drives the T-shaped plate 54 and the piston 55 to reset. At this time, the gas enters the interior of the oil storage tank 59 along the oil inlet pipe 510, and when the punching block 12 moves down to the lowest position, the L-shaped plate 58 pushes the T-shaped plate 54 to move down a certain distance, thereby ensuring that the amount of lubricating oil added each time is constant, reducing the waste of lubricating oil, reducing the steps of manually applying lubricating oil, and greatly ensuring the safety of the staff.

[0028] like Figure 6 - Figure 7As shown, the rotating assembly 56 includes a cavity 561 opened on both sides of the movable mold 10, an annular rack 564 fixed on the outer surface of the annular frame 51 near the bottom, and a rack groove 568 opened on one side of the lower surface of the stamping block 12, a third rack 5610 is slidably connected inside the rack groove 568, a second spring 569 is fixedly connected to one side of the third rack 5610, a transmission shaft 563 is rotatably connected to one side of the inner surface of the cavity 561, a second gear 567 is fixedly connected to the outer surface of the transmission shaft 563, a first gear 565 is fixedly connected to one side of the transmission shaft 563, a magnet 562 is fixedly connected to the bottom of the cavity 561, and a through groove 566 is opened at the top of the cavity 561.

[0029] One side of the second spring 569 is fixedly connected to one side of the inner surface of the rack groove 568, the first gear 565 and the annular rack 564 are meshed with each other, the third rack 5610 and the second gear 567 are meshed with each other, and the material of the third rack 5610 is metal iron.

[0030] Although during cold forging, each stamping can spray the lubricating oil in the oil storage tank 59 to lubricate the inner wall of the forming groove 14, the position of the oil outlet 53 is fixed, and the position of the lubricating oil is also fixed. There is still greater friction at the position where lubrication is lacking. Therefore, when the stamping block 12 moves downward, the stamping block 12 synchronously drives the third rack 5610 to move downward, and the third rack 5610 moves downward and passes through the interior of the through groove 566. The third rack 5610 and the second gear 567 contact and mesh with each other, and the third rack 5610 continues to move downward, driving the second gear 567 to rotate. The second gear 567 drives the first gear 565 to rotate synchronously through the transmission shaft 563, and the first gear 565 drives the annular rack 564 to rotate. The annular rack 564 drives the annular frame 51 to rotate a certain distance inside the movable mold 10. When the third rack 5610 drops to the lowest point and approaches the magnet 562, the magnet 562 drives the third rack 5610 through magnetic force. The third rack 5610 is adsorbed, and slides inside the rack groove 568 to compress the second spring 569. The third rack 5610 slides inside the through groove 566 at the same time. The third rack 5610 and the second gear 567 are separated from each other. When the stamping block 12 moves up, the third rack 5610 moves up at the same time to slide on the surface of the magnet 562, and the second gear 567 no longer slides. When the third rack 5610 and the magnet 562 are separated from each other, under the elastic force of the rack groove 568, the third rack 5610 is reset again, so that each time the stamping block 12 falls, the third rack 5610 and the second gear 567 cooperate to drive the annular frame 51 to rotate a certain distance, and continuously change the position of the oil outlet hole 53, so that the lubricating oil can lubricate a larger area of ​​the inner wall of the forming groove 14, further reducing the friction, and when the annular frame 51 rotates, the oil inlet pipe 510 slides inside the annular groove 511, and will not hinder the rotation of the annular frame 51.

[0031] like Figure 8 As shown, the oil collecting assembly 57 includes a bucket-shaped groove 571 opened at the top of the fixed mold 9 and a slot 576 opened at the bottom of the fixed mold 9, the top of the inner surface of the bucket-shaped groove 571 is fixedly connected to a support plate 572, the bottom of the support plate 572 is fixedly connected to a threaded rod 575, an oil collecting cylinder 573 is slidably arranged at the bottom of the bucket-shaped groove 571, and an internal threaded sleeve 574 is fixedly connected to the bottom of the oil collecting cylinder 573.

[0032] The bottom of the threaded rod 575 extends to the inside of the internal threaded sleeve 574 and is connected to each other through threads. The bottom of the oil collecting cylinder 573 extends to the inside of the slot 576. The upper surface of the support plate 572 is flush with the upper surface of the fixed mold 9.

[0033] Each time the stamping and cold forging is performed, a certain amount of lubricating oil will be squeezed out from the oil storage tank 59. As the lubricating oil is continuously squeezed out, more and more lubricating oil will gather on the inner wall of the forming groove 14 and flow along the inner wall of the forming groove 14. At this time, the lubricating oil flows to the edge of the bottom of the inner wall of the forming groove 14, and the lubricating oil drips onto the inner wall of the bucket-shaped groove 571. The lubricating oil enters the oil collecting barrel 573 along the bucket-shaped groove 571 to be collected. After a period of time, when the lubricating oil inside the oil collecting barrel 573 is about to be collected full, the oil collecting barrel 573 is rotated to drive the internal threaded sleeve 574 to rotate, and the oil collecting barrel 573 is removed from the bottom of the bucket-shaped groove 571, and the collected lubricating oil is reused to avoid waste of lubricating oil.

[0034] like Fig. 9 As shown, the positioning assembly 6 includes two slide grooves 61 opened on both sides of the bottom of the groove 13, a transmission gear 68 rotating on the front and rear sides of the bottom of the groove 13 and a contact plate 65 sliding on one side of the inner surface of the groove 13, the bottom of the contact plate 65 is hinged with a hinge rod 66, the two slide grooves 61 are internally slidably connected with a clamping assembly 69, the two clamping assemblies 69 are fixedly connected with a connecting rod 62 on the front and rear sides of the side away from each other, the two connecting rods 62 on the same side are fixedly connected with a second rack 67 on one side, and the two connecting rods 62 on the other side are fixedly connected with a first rack 63 on one side, a coil spring 610 is arranged on the outer surface of the transmission gear 68, and one clamping assembly 69 is provided with an elastic telescopic rod 64.

[0035] The transmission gear 68 is rotatably connected to the bottom of the groove 13 through the shaft, the coil spring 610 is sleeved on the outer surface of the shaft, the teeth of the first rack 63 and the second rack 67 are opposite, the first rack 63 and the second rack 67 are both meshed with the transmission gear 68, the elastic telescopic rod 64 is composed of a telescopic sleeve, a telescopic rod and a return spring, and the return spring is fixed on one side of the telescopic sleeve, the telescopic rod is fixedly connected to the other side of the return spring, one end of the hinged rod 66 is hinged to one side of the telescopic rod, and the contact plate 65 is connected to the inner surface of the groove 13 through the connecting groove.

[0036] When cold forging the aluminum alloy plate, it is necessary to ensure that the aluminum alloy plate is accurately placed at the stamping position. If the position is too offset, the quality of the cold forging will be greatly reduced, and the defective rate will increase. Therefore, when the aluminum alloy plate is placed inside the groove 13 and located between the two clamping assemblies 69, when the stamping block 12 falls, the stamping block 12 will contact the surface of the contact plate 65, and the contact plate 65 is connected to the inner surface of the groove 13 through the connecting groove, so that the contact plate 65 moves downward, pushing one end of the hinge rod 66, and driving the clamping assembly 69 in the slide groove 6 through the elastic telescopic rod 64. 1, a clamping assembly 69 moves through the connecting rod 62 to drive the second rack 67 to move, and drives the first rack 63 to move toward the center synchronously through the transmission gear 68, driving the other clamping assembly 69 to move toward the center, and the aluminum alloy plate is squeezed, and the elastic telescopic rod 64 will compress the return spring inside it, so as to ensure that the elastic telescopic rod 64 has a certain buffer distance, so that when the stamping block 12 moves down smoothly, the aluminum alloy plate can be effectively clamped and fixed. When the stamping block 12 leaves, the clamping assembly 69 is reset under the action of the coil spring 610.

[0037] like Fig.10 As shown, the clamping assembly 69 includes a mounting block 691 that slides inside the slide groove 61. Two slots 692 are provided inside the mounting block 691. Insert blocks 694 are slidably connected inside the two slots 692. A displacement bar 693 is fixedly connected to one side of the two insert blocks 694.

[0038] The insert block 694 and the slot 692 are T-shaped, a rubber pad is provided inside the slot 692, and one side of the mounting block 691 is fixedly connected to one side of the telescopic sleeve.

[0039] After a long period of high-intensity work, the part of the replacement strip 693 that contacts the aluminum alloy will be worn, which will cause the replacement strips 693 on both sides to easily deviate when clamping the aluminum alloy plate, and the clamping will be unstable. Therefore, when a certain degree of wear appears on the surface of the replacement strip 693, the replacement strip 693 is pulled upward, the replacement strip 693 is removed from the mounting block 691, and a new replacement strip 693 is installed in the mounting block 691, thereby improving the clamping effect of the mounting block 691 and avoiding the loss caused by wear and tear that affects the quality of cold forging.

[0040] Instructions for use: When the hydraulic push rod 11 drives the punch block 12 to move toward the inside of the movable mold 10, the punch block 12 drives the L-shaped plate 58 to move downward at the same time. The L-shaped plate 58 moves downward to press the T-shaped plate 54 downward, and at the same time compresses the two first springs 52. The T-shaped plate 54 drives the piston 55 to slide inside the oil storage tank 59, and squeezes the lubricating oil inside the oil storage tank 59 into the inside of the annular frame 51 through the oil inlet pipe 510. The lubricating oil enters the inside of the annular frame 51 and then flows out through the oil outlet hole 53. The lubricating oil flows along the inside of the molding groove 14 to lubricate the surface of the molding groove 14. When the punch block 12 moves downward, the punch block 12 synchronously drives the third rack 5610 to move downward, and the third rack 5610 moves downward and passes through the interior of the through slot 566. The third rack 5610 and the second gear 567 contact and mesh with each other, and the third rack 5610 continues to move downward, driving the second gear 567 to rotate. The second gear 567 drives the first gear 565 to rotate synchronously through the transmission shaft 563. The first gear 565 drives the annular rack 564 to rotate, and the annular rack 564 drives the annular frame 51 to rotate a certain distance inside the movable mold 10. The lubricating oil flows to the edge of the bottom of the inner wall of the forming groove 14 , and the lubricating oil drips onto the inner wall of the bucket-shaped groove 571 . The lubricating oil flows along the bucket-shaped groove 571 into the oil collecting cylinder 573 to be collected.

[0041] The two clamping assemblies 69 move synchronously under the transmission of the transmission gear 68 to fix the aluminum alloy plate at the center of the stamping. At the same time, the cooperation between the various components of the clamping assembly 69 can replace the replacement strip 693 to ensure the fixing effect. After the cold forging is completed, the electric push rod 3 is started to push the movable mold 10 to one side. The movable mold 10 slides on the outer surface of the slide rod 8 through the sliding sleeve 7. When the molding groove 14 moves away from the top of the fixed mold 9, the molded parts inside the molding groove 14 fall into the collection frame prepared in advance.

[0042] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
