Description

Technical Field

[0001] This utility model belongs to the field of mold handling technology, specifically a stamping mold handling vehicle. Background Technology

[0002] A stamping die is a special piece of equipment used in cold stamping processes. It applies pressure to metal or non-metal materials using a die mounted on a press, causing them to separate or plastically deform, thereby obtaining the desired parts or semi-finished products. It achieves manufacturing through processes such as blanking (separation) or forming (deformation).

[0003] In the stamping workshop, the replacement, adjustment, and handling of molds are frequent and arduous tasks. To process stamped parts of different sizes and shapes, molds need to be taken from a special mold rack for replacement. Usually, a gantry crane is used to hook the lifting lugs of the stamping mold for hoisting, lifting the mold from the mold rack to the press mold base. However, the gantry crane has large swings during hoisting, making installation and alignment difficult. The transfer of molds requires them to be suspended in the air for a long time, which poses a safety hazard. Alternatively, a pallet jack can be used for handling. Ordinary pallet jacks can only handle molds on the ground and are powerless to handle molds placed on the second or third layer of mold racks. Utility Model Content

[0004] To address the problems of excessive swaying during hoisting, difficulty in installation and alignment, and the inability of ordinary pallet jacks to move molds at elevated locations in existing stamping die handling systems, this utility model provides a stamping die handling vehicle.

[0005] This utility model is achieved through the following technical solution:

[0006] A stamping die transport vehicle includes an electric pallet jack. A base is fixedly connected to the upper side of the electric pallet jack. Two spaced columns are connected to the base. Guide grooves are provided on opposite sides of the two columns. Slide plates are slidably connected to the two guide grooves. A lifting mechanism capable of raising and lowering the slide plates is connected to the base. Cantilever cylinders are connected to both ends of the sidewalls of the slide plates. Slide rods are slidably nested inside the two cantilever cylinders. A first telescopic rod is connected to the cantilever cylinder. The telescopic end of the first telescopic rod is connected to the slide rod. A first bracket is rotatably connected to the side of each slide rod. A guide pulley is rotatably connected to the first bracket. A second bracket is connected to the slide plate. Two reels are rotatably connected to the second bracket. A power mechanism for driving the reels to rotate is connected to the slide plate. Ropes are wound on the two reels. One end of the rope extends and wraps around the guide pulley, and can be hung on the stamping die.

[0007] A further improvement of this utility model is that the lifting mechanism includes a second telescopic rod connected and installed on the base, a sprocket is rotatably connected and installed on the upper side of the second telescopic rod, a chain is connected and installed on the base, and the side of the chain away from the base passes around the sprocket and is connected and installed to the slide plate.

[0008] A further improvement of this utility model is that the power mechanism includes a motor and a worm gear reducer connected and mounted on the slide plate, the output shaft of the motor is drivenly connected to the worm gear reducer, and the output shaft of the worm gear reducer is drivenly connected to the reel.

[0009] A further improvement of this utility model is that a tray is connected and installed on the electric pallet jack.

[0010] A further improvement of this utility model is that a support mechanism is connected and installed on the lower side of the tray. The support mechanism includes a fixed frame connected and installed on the tray, a support arm is slidably embedded in the fixed frame, and a support leg is connected and installed on the lower side of the support arm.

[0011] A further improvement of this utility model is that a connecting block is connected and installed at the free end of the rope, and branch slings are connected and installed on both sides of the connecting block, with lifting rings connected and installed on the branch slings.

[0012] A further improvement of this utility model is that the lifting ring is an opening that is wider at the top and narrower at the bottom.

[0013] A further improvement of this utility model is that a support roller that cooperates with the rolling support of the column is rotatably connected to the side of the cantilever cylinder.

[0014] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0015] In use, the operator drives the electric pallet jack to the mold rack where the stamping die is stored, aligns the cantilever cylinder with the stamping die, activates the lifting mechanism to raise the slide plate to the top of the stamping die to be retrieved, and then moves the electric pallet jack closer to the stamping die, suspending the rope wound on the guide pulley directly above the stamping die. If the length is insufficient, the first telescopic rod can be activated to extend the slide rod, and the power mechanism can be activated to rotate the reel, causing the rope to fall. The rope is then tied to the lifting lugs on both sides of the stamping die, and the power mechanism is activated to tighten the rope, thus lowering the stamping die. The device is designed to lift the die, retract the first telescopic rod, and retract the electric pallet jack, allowing the stamping die to move away from the die holder. The lifting mechanism then lowers the die onto the forks of the electric pallet jack, which moves it to the press. The cantilever cylinder is aligned with the press mounting throat. The lifting mechanism then raises the die, extending the first telescopic rod and its sliding rod to deliver the die into the press. Finally, the power mechanism rotates the reel, causing the rope to slowly lower the die, completing the die transport. This device features a rope on the electric pallet jack capable of hoisting the die. The rope can be fixed at any angle to accommodate dies of varying widths. The rotating first support ensures the guide pulley always guides the rope's rotation, avoiding the problems of large swaying during overhead crane hoisting, difficult alignment during installation, and the inability of ordinary pallet jacks to handle dies at high positions. This design offers superior flexibility and maneuverability. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] like Figure 1-5 As shown, this utility model discloses a stamping die transport vehicle, including an electric pallet jack 1. One side of the electric pallet jack 1 has a battery, motor, and hydraulic device, which can provide power and act as a counterweight, and is equipped with an emergency stop brake. A base 2 is fixedly connected to the upper side of the electric pallet jack 1. Two spaced columns 3 are connected and installed on the base 2. Guide grooves 4 are provided on opposite sides of the two columns 3. Slide plates 5 are slidably connected to the two guide grooves 4. A lifting mechanism 6 capable of raising and lowering the slide plates 5 is connected and installed on the base 2. Square cantilever cylinders 7 are connected and installed at both ends of the sidewalls of the slide plates 5. Sliding rods 8 are slidably nested inside each of the two cantilever cylinders 7. The slide plate 5 is internally connected to a first telescopic rod 9, the telescopic end of which is connected to a slide rod 8. Both slide rods 8 are rotatably connected to a first bracket 10 on their sides. A guide pulley 11 is rotatably connected to the first bracket 10. A second bracket 12 is connected to the slide plate 5. Two reels 13 are rotatably connected to the second bracket 12. A power mechanism 14 for driving the reels 13 to rotate is connected to the slide plate 5. Ropes 15 are wound around the two reels 13. The telescopic mechanism uses multi-strand steel cables to ensure strength. One end of the rope 15 extends around the guide pulley 11 and can be attached to the stamping die.

[0025] In use, the operator drives the electric pallet jack 1 to the mold rack where the stamping mold is stored, aligns the cantilever cylinder 7 with the stamping mold, activates the lifting mechanism 6 to raise the slide plate 5 to the upper side of the stamping mold to be retrieved, and drives the electric pallet jack 1 to move closer to the stamping mold, so that the rope 15 wound on the guide pulley 11 is suspended directly above the stamping mold. If the length is insufficient, the first telescopic rod 9 can be activated to extend the slide rod 8, and the power mechanism 14 can be activated to rotate the reel 13, causing the rope 15 to fall. The rope 15 is then tied to the lifting lugs on both sides of the stamping mold, and the power mechanism 14 is activated to tighten the rope 15. The stamping die is lifted, the first telescopic rod 9 is retracted, and the electric pallet jack 1 is reversed, allowing the stamping die to leave the die holder. The lifting mechanism 6 is then activated to lower the die, placing it on the forks of the electric pallet jack 1. The electric pallet jack 1 transports the stamping die to the press, aligning the cantilever cylinder 7 with the press mounting throat. The lifting mechanism 6 is then activated to raise the die, and the first telescopic rod 9 is extended, causing the sliding rod 8 to extend and deliver the die into the press. Finally, the power mechanism 14 is activated to rotate the reel 13, causing the rope 15 to slowly lower the die, completing the die transport. This device, by installing a rope 15 on the electric pallet jack 1 to hoist the stamping die, allows the rope 15 to be fixed at any angle, accommodating dies of different widths. Simultaneously, the first support 10 can rotate, ensuring the guide pulley 11 always guides the rope 15, avoiding the problems of large swaying during overhead crane hoisting, difficult installation and alignment, and the inability of ordinary pallet jacks to transport dies at high positions. This device offers good flexibility and maneuverability.

[0026] It should be noted that during the empty transport process, the electric pallet jack 1 needs to lower the sliding plate 5 to prevent the risk of tipping over due to an excessively high center of gravity. In case of danger, the emergency stop button should be pressed immediately. The control panel is integrated into the electric pallet jack 1, and corresponding operations can be performed by pressing the corresponding buttons. To improve the structural compactness and ensure that the two reels 13 are coaxially connected, and to ensure that the rope 15 is correctly guided, a fixed pulley needs to be connected and installed on the cantilever drum 7 to change the pulling direction of the rope 15, ensuring that the rope 15 does not rub against the edge of the reel 13 and ensuring the safe operation of the rope 15.

[0027] The lifting mechanism 6 includes a second telescopic rod 61 connected and installed on the base 2. The second telescopic rod 61 is a hydraulic rod. A sprocket 62 is rotatably connected and installed on the upper side of the second telescopic rod 61. A chain 63 is connected and installed on the base 2. The side of the chain 63 away from the base 2 passes around the sprocket 62 and is connected and installed to the slide plate 5. In use, the hydraulic system integrated on the electric pallet jack 1 is activated, causing the second telescopic rod 61 to rise. This causes the chain 63 to rotate on the sprocket 62. Since one side of the chain 63 is fixed, the chain 63 connected to the slide plate 5 is pulled up, thereby raising the slide plate 5. This lifting mechanism 6 is used in pairs, with one on each side of the column 3. When the second telescopic rod 61 is lowered to its lowest position, the slide plate 5 can also be lowered to its lowest position. This allows the device to lower the slide plate 5 to its lowest position when the vehicle is traveling empty, thus lowering the center of gravity and improving stability. At the same time, when the second telescopic rod 61 extends, the sprocket 62 rises, and the chain 63 pulls the slide plate 5 to rise at twice the speed of the telescopic rod extension, thus amplifying the stroke and making the structure more compact.

[0028] The power mechanism 14 includes a motor 141 and a worm gear reducer 142 connected and mounted on the slide plate 5. The output shaft of the motor 141 is driven by the worm gear reducer 142, and the output shaft of the worm gear reducer 142 is driven by the reel 13. The worm gear reducer 142 has a self-locking function, which ensures that the reel 13 will not reverse due to load when the motor 141 is de-energized, maintaining the hoisting state, ensuring high safety, and providing sufficient torque due to its large transmission ratio.

[0029] The electric pallet jack 1 is equipped with a tray 16. The tray 16 has uprights around its perimeter, which can restrain the position of the stamping die and prevent it from slipping and being damaged on slopes or other locations. At the same time, the tray 16 can accommodate more dies of different sizes and provide stable support.

[0030] The pallet 16 is equipped with a support mechanism 17 on its lower side. The support mechanism 17 includes a fixed frame 171 connected to and mounted on the pallet 16. A support arm 172 is slidably fitted inside the fixed frame 171, and a support leg 173 is connected and mounted on the lower side of the support arm 172. When it is necessary to lift the stamping die, the support arms 172 on both sides are pulled out from the fixed frame 171, the electric pallet jack 1 is activated, its chassis is lowered, and the support leg 173 contacts the ground, providing stable support for the electric pallet jack 1 and preventing the risk of overturning.

[0031] The free end of the rope 15 is connected to a connecting block 18, and branch slings 19 are connected to both sides of the connecting block 18. Lifting rings 20 are connected to the branch slings 19. By hooking the lifting rings 20 onto the lifting lugs on both sides of the stamping die, the die can be lifted smoothly, improving lifting efficiency.

[0032] The lifting ring 20 is a ring with a larger opening at the top and a smaller opening at the bottom. The upper opening is larger than the diameter of the mold lifting lug, making it easy to slip the lifting ring 20 onto the lifting lug. When the rope 15 is tightened, the smaller opening of the lifting ring 20 locks into the lifting lug, which can firmly clamp the lifting lug and ensure the stability of the lifting.

[0033] The cantilever cylinder 7 is rotatably connected to a support roller 21 that rolls and supports the column 3. The support roller 21 provides support to the cantilever cylinder 7 by pressing the side of the column 3, thereby increasing the support force of the slide plate 5 and the cantilever cylinder 7 and reducing wear on the guide groove 4.

[0034] When the stamping die needs to be moved, the electric pallet jack 1 is aligned with the stamping die to be moved on the die holder. The support arm 172 is extended, and the chassis of the electric pallet jack 1 is lowered so that the support legs 173 provide stable support for the device. The first telescopic rod 9 is activated to extend, causing the slide bar 8 to extend. The rope 15 is suspended directly above the stamping die. The rope 15 is lowered so that the lifting ring 20 is put on the lifting lug. The motor 141 drives the reel 13 to rotate through the worm gear reducer 142, causing the rope 15 to tighten and lift the stamping die. Then, the first telescopic rod 9 is retracted, the chassis of the electric pallet jack 1 is lifted, and the support arm 172 is retracted. The electric pallet jack 1 is then operated to move backward. When the die leaves the die holder, the die is placed in the tray 16. The electric pallet jack 1 is then moved to transport the stamping die to the press. The installation is carried out by reversing the operation. This device uses a rope 15 on an electric pallet jack 1 to lift and suspend the stamping die. The rope 15 can be fixed at any angle to accommodate dies of different widths. At the same time, the first support 10 can rotate, so that the guide pulley 11 can always guide the rotation of the rope 15. This avoids the problems of large swaying during overhead crane hoisting, difficulty in installation and alignment, and the inability of ordinary pallet jacks to move dies at high positions. It has good stability, flexibility and adaptability.

[0035] It should be noted that when the first telescopic rod 9 extends and retracts, the controller detects a signal and controls the motor 141 to drive the reel 13 to rotate, matching the extension length of the rope 15, so as to ensure that the drooping length of the rope 15 remains unchanged when the slide bar 8 extends and retracts.

[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
