[0002] Gears refer to mechanical components with teeth on the rim that can continuously mesh to transmit motion and power. The forming process mainly includes forging, heat treatment, rough turning, fine turning, milling and other processes. Among them, hot die forging is mostly used for forging, and the specific operations are as follows: heating the blank, loading the blank into the mold of the stamping equipment, stamping and forming, and taking out the formed blank. Among these operations, the loading operation of the blank requires manual use of pliers to clamp the blank in the heating furnace into the mold and align it.

DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0034] like Figure 1-Figure 8 As shown, a gear blank stamping forming device proposed in one embodiment of the present application includes a hydraulic press 1, a workbench 101 is constructed on the hydraulic press 1, a movable crossbeam 102 located directly above the workbench 101 is slidably installed on the hydraulic press 1, a lower mold is installed on the workbench 101, and an upper mold is installed on the movable crossbeam 102, and further includes:

[0035] The feeding mechanism 2 includes a carrier 201 fixedly connected to one side of the workbench 101, a heating furnace 202 is fixedly connected to the carrier 201, a guide frame 203 inserted into the heating furnace 202 is slidably installed on the carrier 201, and a driving member 3 for driving the guide frame 203 to reciprocate is installed on the carrier 201. It should be noted that the heating furnace 202 is an existing medium frequency furnace structure, and its internal structure has a horizontally arranged column hole. Generally, a blank is added at one end manually, so that a blank heated at the other end falls down. Some equipment also adopts an automatic feeding structure, but the discharging principle is still to extrude the original blank after adding a blank. The guide frame 203 is set to an inclined shape so that the extruded blank can automatically slide into the lower mold, and the guide frame 203 is driven by the driving member 3 to slide back and forth, so as to be able to move out of the range of the lower mold and the upper mold after the discharging is completed, so as to avoid damage to the device during stamping and ensure the normal operation of the equipment;

[0036] The material-cutting part 4 is straightened, and includes a support frame 401 fixedly connected to the side of the workbench 101, a crossbar 402 fixedly connected to the support frame 401, an outer tube 403 is slidably sleeved on the crossbar 402, and a mounting frame 404 is fixedly connected to the end of the outer tube 403. A transmission member 5 for driving the outer tube 403 to move and connected to the driving member 3 is installed on the workbench 101, and two clamping plates 405 arranged opposite to each other are hinged on the mounting frame 404. A linkage member 406 connected to the crossbar 402 is arranged in the mounting frame 404. When the outer tube 403 extends relative to the crossbar 402, the two clamping plates 405 are mutually connected to form When the outer tube 403 contracts compared to the cross bar 402, the two clamping plates 405 are formed to maintain the current state and move a certain distance and then move away from each other. The transmission member 5 is mainly set to ensure that the driving member 3 can synchronously drive the outer tube 403 to move when driving the guide frame 203 to move, so as to ensure the synchronous operation of the two. That is, when the guide frame 203 moves to the lower mold, the two clamping plates 405 are also on the lower mold and close to each other, which are used to wrap and guide the blank that slides off the guide frame 203, so that it stands upright in the lower mold to avoid tipping, and ensure the subsequent smooth stamping.

[0037] The switching ejector 6 is arranged between the mounting frame 404 and the cross bar 402, and is used to prevent the blank from being separated from the clamping plate 405. It should be noted that the switching ejector 6 has two states. One is when the mounting frame 404 enters the upper part of the lower mold for the first time, that is, during the loading operation, the switching ejector 6 is used to prevent the blank from moving with the clamping plate 405. The second is when the mounting frame 404 enters the upper part of the lower mold for the second time, that is, during the unloading operation, the switching ejector 6 is used to eject the blank from the clamping plate 405 after the blank is moved out of the lower mold, so as to facilitate the loading and unloading operations.

[0038] The collecting part 7 is installed on the side of the hydraulic press 1 and is located below the straightening and unloading part 4. When the blank is ejected, it will automatically fall into the collecting part 7 to avoid rolling around and causing harm to personnel, thereby increasing safety;

[0039] When the device is in use, the blanks need to be placed in the heating furnace 202 for heating in sequence. At this time, the guide frame 203 is in the upper position, that is, one end is inserted into the port of the heating furnace 202, and the lower end of the guide frame 203 is in the outer range of the lower mold. When loading is required, the guide frame 203 is driven downward by the driving member 3 to form a slope, and one end is docked with the lower end of the port of the heating furnace 202, and the other end is docked with the lower mold. At the same time, the outer tube 403 can be synchronously driven to extend outward relative to the cross bar 402 through the transmission of the transmission member 5, that is, the installation frame 404 is driven to move toward the upper part of the lower mold. When the installation frame 404 moves, the two clamps 405 are close to each other, and after stopping the movement, the clamps 405 form a U-shaped groove with the same diameter as the blank, and the U-shaped groove is docked with the port of the guide frame 203 and is in the center of the lower mold. Then, a new blank is added to the heating furnace 202, so that a blank heated inside is squeezed out and moves along the guide frame 2 03 slides into the lower mold and is wrapped by the U-shaped groove formed by the two clamping plates 405 when entering the lower mold, so as to guide and align the blank vertically to ensure smooth subsequent stamping and forming. When the guide frame 203 moves up, it will also synchronously drive the outer tube 403 to retract onto the cross bar 402. At this time, the blank is resisted by switching the ejector 6 to prevent the blank from moving with the two clamping plates 405. After stamping and forming, the guide frame 203 moves downward again, synchronously driving the outer tube 403 and the mounting frame 404 to extend and move, so that the clamping plates 405 clamp the blank. This time, the heating furnace 202 is not operated and no material is required to be discharged. Then, the linkage 406 is used to make the clamping plates 405 take the blank away from the lower mold and then open it, and the switching ejector 6 is used to eject it and drop it into the collecting part 7. The loading and unloading operations do not require manual operation, which saves a lot of manpower, and there is no risk of high-temperature blanks or blanks falling due to accidental manual operation, which ensures the safety of personnel and increases safety.

[0040] like Figure 5As shown, in some embodiments, an extension furnace 2021 is configured at one end of the heating furnace 202, and an inclined groove 2022 for inserting the guide frame 203 is configured at the bottom of the extension furnace 2021. A cover plate 2023 is hingedly connected to the side of the inclined groove 2022 close to the guide frame 203. The upper surface of the cover plate 2023 is flush with the inner hole of the extension furnace 2021 and the end thereof abuts against the other side of the inclined groove 2022. The inclined groove 2022 is arranged at the bottom side of the discharge port of the extension furnace 2021. When the guide frame 203 moves upward, it will be inserted into the inclined groove 2022 at an angle, and the extension furnace 2021 will be pressed. The column hole in 021 is partially blocked to prevent the blank from continuing to move forward and falling, thereby increasing safety. When the guide frame 203 moves downward, it will gradually move out of the extension furnace 2021 until it docks at the lower side of the end of the extension furnace 2021. When inserted into the extension furnace 2021, the guide frame 203 will push open the cover plate 2023, and when moved out of the extension furnace 2021, the cover plate 2023 will automatically flip down and dock with the other side of the chute 2022, so that the blank can pass over the chute 2022, avoiding the blank from being stuck in the chute 2022, thereby increasing the safety of the device.

[0041] like Figure 4 As shown, in some embodiments, the guide frame 203 includes a U-shaped frame 2031, and convex strips 2032 are constructed on both sides of the U-shaped frame 2031. A slide groove 2011 is constructed on the carrier 201 and is inclined toward the lower mold. Grooves 2012 that are inserted into the convex strips 2032 are constructed on both sides of the slide groove 2011. The setting of the U-shaped frame 2031 can guide the sliding of the blank to prevent the blank from falling halfway, thereby increasing safety. The convex strips 2032 and the grooves 2012 can guide the U-shaped frame 2031 when sliding in the slide groove 2011, thereby ensuring the inclined sliding position of the U-shaped frame 2031, so that it can accurately dock with the lower mold and the extension furnace 2021, ensuring the smooth falling of the blank and entering the U-shaped groove between the two clamping plates 405, which is convenient for positioning and adjustment.

[0042] like Figure 4-Figure 5 As shown, in some embodiments, the driving member 3 includes a rack 301 constructed at the bottom of the guide frame 203 along the length direction thereof, a driving motor 302 is fixedly connected to the carrier frame 201, and a driving gear 303 meshing with the rack 301 is fixedly connected to the output shaft of the driving motor 302. The driving gear 303 is driven to rotate forward and reversely by the forward and reverse rotation of the driving motor 302, so as to realize the reciprocating movement of the rack 301, thereby driving the U-shaped frame 2031 to move forward and backward along the slide groove 2011.

[0043] like Figure 8As shown, in some embodiments, the linkage member 406 includes a double-sided tooth block 4061 that slides through the installation frame 404, and the hinged ends of the two clamping plates 405 are both configured with a sector tooth block 4063. The double-sided tooth block 4061 is meshed with the two sector tooth blocks 4063. A telescopic spring 4062 is connected between one end of the double-sided tooth block 4061 and the cross bar 402. When the outer tube 403 extends relative to the cross bar 402, that is, moves toward the lower mold, it will drive the installation frame 404 and the clamping plates 405 to move. 405 moves toward the top of the lower mold, while the cross bar 402 and the linkage 406 do not move. Therefore, when the installation frame 404 moves, the two sector tooth blocks 4063 will be driven to move synchronously. During the initial displacement, the sector tooth block 4063 will be driven to move together. When the elastic force of the subsequent telescopic spring 4062 is greater than the friction force between the sector tooth block 4063 and the double-sided tooth block 4061, the sector tooth block 4063 will mesh with the double-sided tooth block 4061, thereby driving the two clamping plates through the rotation of the sector tooth block 4063. The elasticity of the telescopic spring 4062 will be used to offset the breakage of the splint 405. When the outer tube 403 moves in the reverse direction, the telescopic spring 4062 will first be elastically reset until the telescopic spring 4062 is compressed to a point where the elastic force is greater than the friction force. The double-sided tooth block 4061 will then drive the fan tooth block 4063 to flip over, thereby forming an opening operation after the splint 405 moves a certain distance. Because the double-sided tooth block 4061 and the cross bar 402 are connected by the telescopic spring 4062, the end of the splint 405 can be made to contact the formed blank and then flip over to approach each other during the second movement of the outer tube 403. After flipping, the splint 405 will not break due to continued movement, and the elasticity of the telescopic spring 4062 will be used to offset the breakage. During the subsequent reverse movement, the blank can be clamped above the collecting piece 7 and then the splint 405 can be opened, which is convenient for unloading operations. The single device has dual functions, which improves the flexibility and functionality of the device.

[0044] like Figure 7 As shown, in some embodiments, the clamp 405 includes two parallel links 4051 hinged at the corners of the mounting frame 404, and the other ends of the two parallel links 4051 are hinged with an L-shaped plate 4052. V-shaped grooves 4053 are constructed on the opposite surfaces of the two L-shaped plates 4052, and multiple rollers 4054 are rotatably installed in the V-shaped grooves 4053. Two parallel links 4051 are hinged on each L-shaped plate 4052, which can increase the stability after flipping, and cooperate with the V-shaped grooves 4053 to increase the contact area with the blank, further improving the clamping stability of the blank, and the provision of rollers 4054 makes it convenient to cooperate with the switching ejector 6 to eject the blank, prevent the blank from moving with the clamp 405, and increase safety.

[0045] like Fig. 9As shown, in some embodiments, the switching ejector 6 includes a column cavity 601 constructed in the cross bar 402, a piston block 602 is slidably installed in the column cavity 601, one end of the piston block 602 is fixedly connected to an ejector pin 603 that penetrates the cross bar 402 and the double-sided gear block 4061, and one end of the ejector pin 603 is fixedly connected to an arc-shaped piece 604. It should be noted that one end of the column cavity 601 is connected to the existing pressurizing component of the hydraulic press 1 through a hose, and the electromagnetic valve is used to control its on and off. When the blank needs to be ejected, the piston block 602 can be pressurized to drive the ejector pin 6 03, pushes toward the lower mold until it contacts the side of the blank, so that the subsequent clamping plate 405 will not drive the blank to move when it is reset with the installation frame 404, thereby ensuring the position of the blank. When performing the unloading operation, the pressure-applying component is used to extract the oil pressure in the column cavity 601, so that the piston block 602 drives the ejector pin 603 to reset to its original position. This position is used to eject the blank in the clamping plate 405 after the reset, so that the blank can fall downward and enter the collecting piece 7, avoiding the blank from being stuck in the clamping plate 405 and affecting the next operation, thereby increasing safety.

[0046] like Figure 6 As shown, in some embodiments, the collecting member 7 includes a rectangular table 701 fixedly connected to the hydraulic press 1, a feeding frame 702 located below the support frame 401 is placed on the rectangular table 701, a feeding port 703 is constructed on the support frame 401, a slide plate 704 inclined toward the upper surface of the lower mold is fixedly connected in the feeding port 703, a transition slide plate 705 arranged in the opposite direction of the inclination of the slide plate 704 is installed at the bottom of the support frame 401, the feeding port 703 is arranged directly below the end of the initial position of the ejector pin 603, when the blank falls, it will slide downward through the slide plate 704, thereby entering the feeding port 703, and the provision of the transition slide plate 705 can block the falling blank in the middle to prevent the blank from falling directly and causing it to be deformed by impact, thereby increasing safety.

[0047] like Figure 3 As shown, in some embodiments, the transmission member 5 includes an acceleration mechanism 501 arranged on the workbench 101, an external thread 4031 is constructed on the outer tube 403, and a screw sleeve 502 threadedly connected with the external thread 4031 is rotatably installed on the support frame 401. The acceleration mechanism 501 and the output shaft of the drive motor 302 and the screw sleeve 502 are all connected by a pulley transmission. When the drive motor 302 rotates, the acceleration mechanism 501 can synchronously drive the screw sleeve 502 to rotate faster than the drive gear 303, so that the screw sleeve 502 and the external thread 4031 on the outer tube 403 are threadedly matched, and after the guide frame 203 moves to the specified position, the outer tube 403 can also move to the specified position, thereby ensuring the accuracy of the splint 405 in guiding the blank vertically.

[0048] like Figure 3As shown, in some embodiments, the acceleration mechanism 501 includes a rotating shaft 1 5011, a rotating shaft 2 5012 and a rotating shaft 3 5013 rotatably mounted on the workbench 101 and the support frame 401, the rotating shaft 1 5011 and the output shaft of the driving motor 302 and the rotating shaft 3 5013 and the screw sleeve 502 are connected by a pulley transmission, the rotating shaft 1 5011 and the rotating shaft 2 5012 and the rotating shaft 2 5012 and the rotating shaft 3 5013 are connected by a gear transmission, wherein the rotating shaft The number of teeth on the gear 5011 is greater than the number of teeth on the gear on the second shaft 5012, and the second shaft 5012 is also equipped with a second gear, which meshes with the gear on the third shaft 5013 and has a greater number of teeth than the gear on the third shaft 5013, thereby forming double acceleration to ensure that the screw sleeve 502 can produce a quick thread fit with the external thread 4031, so that the outer tube 403 and the mounting frame 404 can move to the top of the lower mold within the same time, thereby ensuring the accuracy of the guidance.
