Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, and in particular to an automated stamping equipment for automobile shock absorber brackets. Background Technology

[0002] Shock absorber brackets are an important component of automotive suspension systems. Their main function is to connect shock absorbers to the vehicle frame. In the production process of shock absorber brackets, stamping technology is a commonly used manufacturing method. Due to its high efficiency, precision, and suitability for mass production, it has become an important means of manufacturing many automotive parts.

[0003] Currently, the most common stamping process involves manually placing the raw material sheet onto the lower die before starting the stamping machine to stamp the sheet. During this process, in order to prevent the sheet from deviating, manual assistance is sometimes required to position the sheet. Furthermore, after stamping, manual demolding is also necessary. This stamping method not only consumes a great deal of physical strength from workers but also poses significant safety hazards. In response to the safety hazards caused by manual material handling and assisted positioning, we propose a new type of automated stamping equipment for automotive shock absorber brackets. Summary of the Invention

[0004] To overcome the aforementioned shortcomings in the prior art, the present invention aims to provide an automated stamping processing equipment for automotive shock absorber brackets that can automatically position and unload materials during the stamping process.

[0005] This invention provides an automated stamping processing equipment for automotive shock absorber brackets, including a support platform and a material receiving conveyor unit disposed on its right side. A frame is mounted on the upper surface of the support platform, and an upper die assembly and an upper die head are respectively mounted on the top of the frame. A lower die base adapted to the upper die head is fixed to the top of the support platform, and a die groove is pre-reserved in the middle of the upper surface of the lower die base. An anti-detachment stepped groove is pre-reserved at the top edge of the die groove. A feeding slide groove penetrating the front is formed on the upper surface of the lower die base, and a feeding tray connected to the feeding slide groove is fixed near the top of the front of the lower die base. During feeding, the raw material sheet is simply pushed along the feeding tray into the middle of the lower die base. At this time, the perimeter of the raw material plate will be restricted by the anti-detachment stepped groove and cannot move, thus forming automatic positioning; the front and rear sides of the support platform are respectively fixed with symmetrical C-shaped support plates near the top, and the top of the two C-shaped support plates are slidably connected with the same horizontally sliding U-shaped sliding rod. The U-shaped sliding rod includes a middle rod and two parallel support rods. The lower surface of the middle rod of the U-shaped sliding rod is fixed with a pressure plate, and a clamping mechanism is provided above the pressure plate. The bottom of the lower mold base is provided with an ejection part; the side of the lower mold base away from the receiving conveyor is fixed with a cantilever support platform, and the top of the cantilever support platform is provided with a positive positioning lifting mechanism adapted to the pressure plate.

[0006] Preferably, the top ends of the two C-shaped support plates are respectively fixed with upward-opening and parallel grooved slide rails II, and the lower surfaces of the two parallel support rods of the U-shaped sliding rod are respectively fixed with anti-torsion rails that form a sliding fit with the grooved slide rails II; an electric cylinder is fixed to the lower surface of the cantilever support platform at the end away from the support platform, and the end of the electric cylinder extension rod is fixed with a needle-shaped abutment rod extending into the support platform, the needle-shaped abutment rod including a composite thick rod and a thin rod, and a sliding insertion hole is opened on the side of the support platform near the electric cylinder; a fan-shaped rotating groove I is opened in the middle of the side of the support platform and the lower mold base near the cantilever support platform, and the top end of the rotating groove I is connected to the mold groove. The bottom is connected, and the bottom end of the first rotating groove is connected to the sliding insertion hole. A bearing seat is fixed on the side of the support platform near the first rotating groove. The ejector part is rotatably connected in the bearing seat. The ejector part includes an arc-shaped toothed rod and two spoke rods. The center of the arc-shaped toothed rod falls on the rotation center of the bearing seat. A top tube that meshes with the ejector part is slidably inserted in the sliding insertion hole. The thin rod of the needle-shaped abutment rod is slidably inserted in the top tube, and the same compression spring is provided between the end of the composite thick rod and the end of the top tube. When the stamping is finished, only the extension rod of the electric cylinder needs to be extended to respond quickly to push the ejector part to run, thereby lifting one end of the support body.

[0007] Preferably, a short shaft is provided on the lower surface of the cantilever support near the electric cylinder, and the short shaft is horizontally positioned above the composite thick rod. An intermediate gear is fixed in the middle of the short shaft. A gear rod is embedded in the middle of the upper surface of the composite thick rod, meshing with the intermediate gear, and a pulley is fixed on the gear rod. Symmetrical L-shaped mounting seats are fixed on the upper surface of the cantilever support near the front and rear sides. The positioning and lifting mechanism also includes bearing assemblies fixed to the tops of the two L-shaped mounting seats. A long shaft is provided between the two bearing assemblies, and the long shaft and the short shaft are mutually... The long shaft is parallel to each other, and two symmetrical drive gears are fixed near the middle of the shaft. A pulley is fixed between the two drive gears and forms a transmission connection with the pulley. The top of the two L-shaped mounting seats is fixed with C-shaped retaining rails that are opposite to each other and parallel to each other. Symmetrical toothed inserts are slidably engaged in the two C-shaped retaining rails. The toothed inserts mesh with the drive gears on their respective sides. Side gears are fixed at both ends of the long shaft, and racks that mesh with the side gears on their respective sides are fixed on the lower surfaces of the two supports of the U-shaped sliding rod.

[0008] Preferably, the two toothed insert rods are provided with flat rods at one end near the lower mold base, and the lower surface of the flat rods is flush with the upper surface of the lower mold base, so that they can be smoothly inserted into the lower surface of the support body during the push-in process.

[0009] Preferably, the distance between the two toothed inserts is greater than the distance between the front and rear ends of the bearing housing, and the distance between the two toothed inserts is less than the width of the lower surface of the bracket body, so as to ensure that the two toothed inserts can lift the bracket body after insertion.

[0010] Preferably, the outer wall of the jacking tube is provided with anti-torsion protrusions, and the inner wall of the sliding hole is provided with guide grooves that are adapted to the size of the anti-torsion slider. The extension direction of the guide grooves is consistent with the center line of the sliding hole, which can ensure that the jacking tube always maintains engagement with the arc-shaped toothed rod in the ejection part during the pushing and pulling process.

[0011] Preferably, the diameter of the first pulley is larger than the diameter of the second pulley, and the diameter of the first pulley is larger than the diameter of the intermediate gear. This allows the first toothed rod in the composite thick rod to only need to be advanced a small distance to drive the toothed insert rod or the U-shaped sliding rod to move a large distance. This ensures that the toothed insert rod and the clamping mechanism are completely removed from the stamping area, thus avoiding affecting the stamping process.

[0012] Preferably, the conveying plane of the receiving conveyor unit is located at a height lower than the upper surface of the lower mold base to facilitate material receiving.

[0013] Preferably, the clamping mechanism includes an L-shaped bearing bracket in the middle of the upper surface of the intermediate rod of the U-shaped sliding rod, and a worm gear reel is provided between the L-shaped bearing bracket and the upper surface of the intermediate rod. Two traction ropes that are centrally symmetrically distributed are wound on the outer circumference of the worm gear reel near its top. The intermediate rod has shaft holes near both ends on its side, and a transmission rod is rotatably connected to each of the two shaft holes. Double-bar clamps are fixed at both ends of the transmission rods. A connecting plate is fixed between the top ends of the two double-bar clamps on the same side. A return spring is fixed at the end of the connecting plate near the worm gear reel, and a spring baffle is fixed at the end of the return spring away from the connecting plate. The other ends of the two traction ropes are respectively fixed in the middle of the corresponding connecting plates. A reduction motor is fixed in the middle of the intermediate rod, and a worm that meshes with the worm gear reel is fixed at the top of the output shaft of the reduction motor.

[0014] Preferably, each of the four double-bar clamps has a hexagonal nut embedded on one side of its bottom end, and each hexagonal nut is screwed with a locking stud. The extension length of the locking stud can be adjusted according to the shape of the bracket body, thereby adapting to the bracket body with irregular structure.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. By setting the ejector at the bottom of the mold groove, and with the setting of the positioning and lifting mechanism, one end of the bracket body can be automatically ejected from the mold groove after the bracket body is stamped. After the bracket body is aligned, it can be gripped by the clamping mechanism. This process does not require manual approach to the upper stamping area of ​​the lower mold base, which greatly improves the safety performance.

[0017] 2. By setting up a positive lifting mechanism driven by an asynchronous electric cylinder, when the jacking tube drives the ejector to the limit height, the ejector stops moving. At this time, the needle-shaped push rod continues to advance, which drives the intermediate gear and short shaft to start rotating, and then drives the two toothed insert rods to move in the opposite direction to the pressure plate, thereby lifting the bracket body with one end raised to a horizontal state.

[0018] 3. With the worm gear reel and the double-bar clamps on both sides, before clamping, simply pull the two traction ropes towards the middle simultaneously. After the bottom of the double-bar clamps covers the top of the raised bracket body, release the traction ropes to clamp the bracket body. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] In this embodiment, refer to Figure 1-9An automated stamping processing equipment for automotive shock absorber brackets includes a support platform 1 and a receiving conveyor unit 2 located on its right side. A frame 5 is mounted on the upper surface of the support platform 1, and an upper die assembly 6 and an upper die head 7 are respectively mounted on the top of the frame 5. A lower die base 3, adapted to the upper die head 7, is fixed to the top of the support platform 1. A die groove 301 is pre-reserved in the middle of the upper surface of the lower die base 3, and an anti-detachment stepped groove is pre-reserved at the top edge of the die groove 301. A feeding slide groove penetrating the front is opened on the upper surface of the lower die base 3, and a feeding tray 14 connected to the feeding slide groove is fixed near the top of the front of the lower die base 3. During feeding, the raw material sheet is simply pushed along the feeding tray 14 into the middle of the lower die base 3. At this time, the periphery of the raw material sheet is restricted by the anti-detachment stepped groove and cannot move, thus achieving automatic positioning. Symmetrical C-shaped support plates 1 are fixed on the front and rear sides of the support platform 1 near the top. 3. The top ends of the two C-shaped support plates 13 are slidably connected by the same horizontally sliding U-shaped sliding rod 9. The U-shaped sliding rod 9 includes a middle rod and two parallel support rods. The lower surface of the middle rod of the U-shaped sliding rod 9 is fixed with a pressure plate 4, and a clamping mechanism 8 is provided above the pressure plate 4. The bottom of the lower mold base 3 is provided with an ejector part 23. A cantilever support 10 is fixed on the side of the lower mold base 3 away from the receiving conveyor group 2, and the top of the cantilever support 10 is provided with a positioning lifting mechanism adapted to the pressure plate 4. By setting the ejector part 23 at the bottom of the mold groove 301, in conjunction with the positioning lifting mechanism, one end of the bracket body 17 can be automatically ejected from the mold groove 301 after the bracket body 17 is stamped. After the bracket body 17 is aligned, it can be gripped by the clamping mechanism 8. This process does not require manual approach to the upper stamping area of ​​the lower mold base 3, which greatly improves the safety performance.

[0031] Reference Figures 2-3 , Figures 5-6 , Figure 9The tops of the two C-shaped support plates 13 are respectively fixed with upward-opening and parallel grooved slide rails 2, and the lower surfaces of the two parallel support rods of the U-shaped sliding rod 9 are respectively fixed with anti-torsion rails 901 that form a sliding fit with the grooved slide rails 2; the lower surface of the cantilever support 10 is fixed with an electric cylinder 11 at the end away from the support platform 1, and the end of the extension rod of the electric cylinder 11 is fixed with a needle-shaped abutment rod 12 extending into the support platform 1. The needle-shaped abutment rod 12 includes a composite thick rod and a thin rod, and a sliding insertion hole 102 is opened on the side of the support platform 1 near the electric cylinder 11. A fan-shaped rotating groove 101 is opened in the middle of the side of the support platform 1 and the lower mold base 3 near the cantilever support 10, and the top of the rotating groove 101 communicates with the bottom of the mold groove 301, and the bottom of the rotating groove 101 communicates with the sliding insertion hole 102. The two phases are connected, and a bearing seat 26 is fixed on the side of the support platform 1 near the rotating groove 101. The ejector part 23 is rotatably connected in the bearing seat 26. The ejector part 23 includes an arc-shaped toothed rod and two spoke rods. The center of the arc-shaped toothed rod falls on the rotation center of the bearing seat 26. A top tube 15 that meshes with the ejector part 23 is slidably inserted in the sliding insertion hole 102. The thin rod of the needle-shaped abutment rod 12 is slidably inserted in the top tube 15, and the same compression spring is provided between the end of the composite thick rod and the end of the top tube 15. By setting the top tube 15 that meshes with the arc-shaped toothed rod and the needle-shaped abutment rod 12, it is possible to quickly respond by simply controlling the extension rod of the electric cylinder 11 to push the ejector part 23 to run, thereby lifting one end of the support body 17.

[0032] Reference Figures 2-3 , Figures 5-6 , Figure 9A short shaft 16 is provided on the lower surface of the cantilever support 10 near the electric cylinder 11. The short shaft 16 is horizontally positioned above the composite thick rod, and an intermediate gear 25 is fixed in the middle of the short shaft 16. A gear rod 1 that meshes with the intermediate gear 25 is embedded in the middle of the upper surface of the composite thick rod, and a pulley 24 is fixed on the gear rod 1. Symmetrical L-shaped mounting seats 1001 are fixed on the upper surface of the cantilever support 10 near the front and rear sides respectively. The positioning and lifting mechanism also includes bearing assemblies fixed to the top of the two L-shaped mounting seats 1001. A long shaft 19 is provided between the two bearing assemblies. The long shaft 19 is parallel to the short shaft 16, and two symmetrical drive gears 18 are fixed near the middle of the long shaft 19. A pulley 24 that forms a transmission connection with the pulley 24 is fixed between the two drive gears 18. The top of the mounting base 1001 is fixed with C-shaped rails 22 that are opposite to each other and parallel to each other. The two C-shaped rails 22 are respectively slidably engaged with symmetrical toothed rods 21. The toothed rods 21 are respectively engaged with the drive gears 18 on their respective sides. Both ends of the long shaft 19 are fixed with side gears 20. The lower surfaces of the two supports of the U-shaped sliding rod 9 are fixed with racks 902 that are engaged with the side gears 20 on their respective sides. By setting a positive lifting mechanism driven asynchronously by the electric cylinder 11, when the top tube 15 drives the ejector part 23 to run to the limit height, the ejector part 23 stops running. At this time, the needle-shaped abutment rod 12 continues to advance, which drives the intermediate gear 25 and the short shaft 16 to start rotating. Then, it drives the two toothed rods 21 to move in the opposite direction to the pressure plate 4, thereby lifting the bracket body 17 with one end raised to a horizontal state.

[0033] Reference Figure 6 , Figure 7 Two toothed insert rods 21 are provided with flat rods at one end near the lower mold base 3, and the lower surface of the flat rods is flush with the upper surface of the lower mold base 3, so that they can be smoothly inserted into the lower surface of the bracket body 17 when pushed forward.

[0034] Reference Figure 4 and Figure 9 The distance between the two toothed rods 21 is greater than the distance between the front and rear ends of the bearing seat 26, and the distance between the two toothed rods 21 is less than the width of the lower surface of the bracket body 17, so as to ensure that the two toothed rods 21 can lift the bracket body 17 after insertion.

[0035] In this invention, the outer wall of the jacking tube 15 is provided with anti-torsion protrusions, and the inner wall of the sliding insertion hole 102 is provided with a guide groove that matches the size of the anti-torsion slider. The extension direction of the guide groove is consistent with the center line of the sliding insertion hole 102, which can ensure that the jacking tube 15 always maintains engagement with the arc-shaped toothed rod in the ejection part 23 during the pushing and pulling process.

[0036] Reference Figures 5-6 The diameter of pulley 24 is larger than that of pulley 2, and the diameter of pulley 24 is larger than that of the intermediate gear 25. With this arrangement, the toothed rod 1 in the composite thick rod only needs to be pushed forward a small section to drive the toothed insert rod 21 or the U-shaped sliding rod 9 to move a large distance. This ensures that the toothed insert rod 21 and the clamping mechanism 8 are completely removed from the stamping area, thus avoiding affecting the stamping process.

[0037] Reference Figure 6 The conveying plane of the receiving conveyor unit 2 is located at a height lower than the upper surface of the lower mold base 3, so as to facilitate material receiving.

[0038] Reference Figure 3 , Figures 7-8 The clamping mechanism 8 includes an L-shaped bearing bracket 801 located in the middle of the upper surface of the intermediate rod of the U-shaped sliding rod 9. A worm gear reel 802 is disposed between the L-shaped bearing bracket 801 and the upper surface of the intermediate rod. Two traction ropes, symmetrically distributed around each other, are wound on the outer circumference of the worm gear reel 802 near its top. Shaft holes 903 are opened near both ends of the side of the intermediate rod, and transmission rods 807 are rotatably connected to both shaft holes 903. Double-rod clamping rods 803 are fixed to both ends of the transmission rods 807. A connecting plate is fixed between the top ends of the two double-rod clamping rods 803 on the same side, and the end of the connecting plate near the worm gear reel 802 is... A return spring 808 is fixed, and a spring baffle 804 is fixed to the end of the return spring 808 away from the connecting plate. The other ends of the two traction ropes are fixed to the middle of the corresponding connecting plates. A reduction motor 805 is fixed in the middle of the intermediate rod. A worm gear that meshes with the worm gear reel 802 is fixed to the top of the output shaft of the reduction motor 805. With the worm gear reel 802 and the double rod clamps 803 on both sides, before clamping, you only need to pull the two traction ropes to the middle at the same time. After the bottom of the double rod clamp 803 covers the top of the raised bracket body 17, you can release the traction ropes to clamp the bracket body 17.

[0039] Among them, the bottom ends of the four double-bar clamps 803 are each fitted with a hexagonal nut on one side, and each hexagonal nut is screwed with a tightening stud 806. The extension length of the tightening stud 806 can be adjusted according to the shape of the bracket body 17, thereby adapting to the bracket body 17 with irregular structure.

[0040] Working principle: When using this device, first lift the upper die head 7 and ensure that the extension rod of the electric cylinder 11 is in the retracted state, i.e., the initial state: At this time, ① the middle rod of the U-shaped sliding rod 9 and the clamping mechanism 8 above it are all located outside the stamping area, i.e., above the receiving conveyor group 2; ② the two toothed insert rods 21 are also located outside the stamping area, i.e., on the side away from the receiving conveyor group 2; ③ the top of the arc-shaped toothed rod in the ejector part 23 is located below the bottom of the mold groove 301; then the raw material plate in the loading tray 14 can be pushed into the stamping process. After the stamping is completed, the formed bracket body 17 will be embedded in the mold groove 301. At this time, the extension rod of the electric cylinder 11 extends, and the end of the bracket body 17 near the ejector 23 will slowly tilt up. When the ejector tube 15 drives the ejector 23 to the limit height, the ejector 23 stops moving. At this time, the needle-shaped push rod 12 continues to advance, which drives the intermediate gear 25 and the short shaft 16 to start rotating. Then, it drives the two toothed insert rods 21 to move in the opposite direction to the pressure plate 4, thereby raising the bracket body 17 with one end tilted up to a horizontal state. Finally, the clamping mechanism 8 is controlled to clamp the bracket body 17, and the electric cylinder 11 is controlled to reset, so that the bracket body 17 can be transported to the receiving conveyor group 2 and put down.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
