Description

Technical Field

[0001] This utility model relates to the field of gear manufacturing technology, and more specifically, to a forging equipment for gear manufacturing. Background Technology

[0002] Gear hot forging refers to heating metal materials to above their recrystallization temperature and then using a mold to plastically form them at high temperatures to obtain high-strength, high-precision gear blanks or near-net-shape gears. An existing composite gear hot forging apparatus, with publication number CN212945200U, includes an apparatus body. A stamping table is fixedly connected to the inner bottom of the apparatus body. A drive shaft is mounted on the top of the apparatus body, a motor is mounted on one side of the drive shaft, and a driving gear is fixedly connected to the outer side of the drive shaft. A driven gear is meshed with the top of the driving gear.

[0003] However, in the above scheme, after the upper and lower dies of the gear hot forging device are used to forge the high-temperature metal material, the upper and lower dies will have debris stuck to them. The stuck debris will be pressed into the surface of the workpiece during subsequent forging, forming pits, scratches or inclusions, resulting in the gear's accuracy and surface finish not meeting the standards. Utility Model Content

[0004] The main purpose of this utility model is to provide a forging equipment for gear production, which can effectively solve the problem in the background art where, after the upper and lower dies cooperate to forge high-temperature metal materials in gear hot forging devices, debris will stick to the upper and lower dies. The stuck debris will be pressed into the surface of the workpiece in subsequent forging, forming pits, scratches or inclusions, resulting in the gear precision and surface finish not meeting the standards.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A forging equipment for gear production includes a base, a die fixedly installed in the middle of the upper surface of the base, a gantry frame fixedly installed on both sides of the base, a cylinder fixedly installed on the upper surface of the gantry frame, and a punch fixedly installed at the output end of the cylinder through the gantry frame.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-7 As shown, a forging equipment for gear production includes a base 1, a die 2 fixedly installed in the middle of the upper surface of the base 1, a gantry frame 3 fixedly installed on both sides of the base 1, a cylinder 4 fixedly installed on the upper surface of the gantry frame 3, and a punch 5 fixedly installed at the output end of the cylinder 4 through the gantry frame 3.

[0027] The upper surface of the base 1 is provided with a cleaning component 6 for cleaning the debris remaining on the surface of the punch 5 and the die 2.

[0028] The cleaning component 6 includes a slide 601, which is opened on one side of the upper surface of the base 1. A slider 602 is slidably disposed in the slide 601. A right-angle bracket 603 is fixedly installed on the upper surface of the slider 602. A connecting pipe 604 is rotatably installed through the upper surface of the right-angle bracket 603. Horizontal pipes 605 are fixedly installed at both ends of the connecting pipe 604. A first nozzle 606 is fixedly installed in the middle of the body of each of the two horizontal pipes 605.

[0029] A number of air holes 607 are opened through the inner wall surface of the connecting pipe 604. A sealing sleeve 608 is fixedly installed on the upper surface of the right angle bracket 603. A sealing plate 609 is fixedly installed on the body of the connecting pipe 604. The sealing plate 609 and the sealing sleeve 608 are interlocked.

[0030] The air inlet pipe 610 is fixedly installed through the body of the sealing sleeve 608.

[0031] The worker connects the output end of the blower to the air inlet pipe 610 via a corrugated pipe. Then, the worker places the high-temperature metal part into the forming cavity of the die 2. The worker then starts the cylinder 4, causing its output end to move the punch 5. Under the cooperation of the punch 5 and the die 2, the high-temperature metal part is hot-forged. The worker then controls the punch 5 to move back to its original position. After the worker removes the formed part, the worker controls the slider 602 to move. The moving slider 602 moves the right-angle bracket 603, causing the horizontal tube 605 to move between the punch 5 and the die 2. Then, the worker starts the blower, allowing gas to enter the horizontal tube 605 through the air inlet pipe 610 and the air hole 607, and finally spray out from the first nozzle 606. This allows the gas to blow away the debris remaining on the surface of the die 2 and the punch 5, cleaning the debris and preventing it from being pressed into the surface of the workpiece during subsequent forging.

[0032] In another embodiment of this utility model, several second nozzles 7 are fixedly installed on both sides of the two horizontal pipes 605, and each second nozzle 7 is obliquely arranged.

[0033] By setting an angled second nozzle 7, the cleaning area for the die 2 and punch 5 is increased, thereby improving cleaning efficiency.

[0034] In another embodiment of this utility model, a first bevel gear 8 is sleeved on one side of the connecting pipe 604, a connecting frame 9 is fixedly installed at the top inside the right angle frame 603, a crossbar 10 is rotatably installed through one side of the connecting frame 9, a second bevel gear 11 is sleeved on one side of the crossbar 10, the second bevel gear 11 meshes with the first bevel gear 8, a first motor 12 is fixedly installed on one side of the right angle frame 603, and one side of the crossbar 10 passes through the right angle frame 603 and is fixedly connected to the output shaft end of the first motor 12.

[0035] Workers start the first motor 12, causing its output shaft to drive the crossbar 10 to rotate, which in turn drives the second bevel gear 11 to rotate. Under the meshing action of the second bevel gear 11 and the first bevel gear 8, the connecting pipe 604 rotates. The rotating connecting pipe 604 can drive the crossbar 605 to rotate, so that the second nozzle 7 can rotate with the connecting pipe 604 as the reference, thereby further increasing the spray range of the second nozzle 7 and further improving the cleaning efficiency.

[0036] When the connecting pipe 604 rotates, the sealing sleeve 608 and the sealing plate 609 work together to ensure that gas can enter the vent 607 without affecting the rotation of the connecting pipe 604, thus preventing gas leakage.

[0037] In another embodiment of this utility model, a support frame 13 is fixedly installed on one side of the right-angle frame 603, and a rotating roller 14 is rotatably installed between the two sides of the inner wall of the support frame 13.

[0038] By setting up the upright frame 13 and the rotating roller 14, the rotating roller 14 and the upright frame 13 can support the right-angle frame 603 without affecting its movement, thus preventing the right-angle frame 603 from bending under stress for a long time.

[0039] In another embodiment of the present invention, a lead screw 15 is rotatably installed between the two sides of the inner wall of the slide groove 601, a slider 602 is threaded on one side of the lead screw 15, and a second motor 16 is fixedly installed on one side of the base 1. One end of the lead screw 15 passes through the slide groove 601 and is fixedly connected to the output shaft end of the second motor 16.

[0040] The staff starts the second motor 16, which drives the lead screw 15 to rotate. The rotating lead screw 15 drives the slider 602 and the right-angle bracket 603 to move by screwing in the thread. The staff does not need to manually move the right-angle bracket 603, which reduces the workload of the staff.

[0041] The working principle of this forging equipment for gear production:

[0042] In operation, the operator connects the output end of the blower to the air inlet pipe 610 via a corrugated pipe. Then, the operator places the high-temperature metal part into the forming cavity of the die 2. The operator then starts the cylinder 4, causing its output end to move the punch 5. Under the combined action of the punch 5 and the die 2, the high-temperature metal part is hot-forged. The operator then controls the punch 5 to move back to its original position. After removing the formed part, the operator controls the slider 602 to move. The moving slider 602 moves the right-angle bracket 603, causing the horizontal tube 605 to move between the punch 5 and the die 2. Then, the operator starts the blower, allowing gas to enter the horizontal tube 605 through the air inlet pipe 610 and the air hole 607, and finally spray out from the first nozzle 606. This allows the gas to blow away the debris remaining on the surface of the die 2 and the punch 5, cleaning the debris and preventing it from being pressed into the workpiece surface during subsequent forging.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
