Description

Technical Field

[0001] This utility model relates to the technical field of stamping blanking auxiliary devices, and in particular to a stamping blanking device. Background Technology

[0002] Stamping is a common manufacturing method in the field of metal forming, enabling various processes such as cutting, forming, and punching of sheet metal. In actual production, for long or large sheet metal, a feeding mechanism is usually required to gradually feed the sheet metal into the stamping station to complete continuous or segmented stamping processes. In existing technologies, the feeding platform is generally equipped with clamping devices and feeding fixtures for positioning and gradually conveying the sheet metal during the stamping process.

[0003] For long plate-shaped metal parts, as the tail section of the sheet metal gradually enters the stamping area, a pulling device is often required outside the feeding end. This device pulls the tail section of the sheet metal into the die to complete the stamping of the remaining portion. After the tail section of the sheet metal is stamped, it needs to be unloaded promptly to ensure the continuity of subsequent production.

[0004] Currently, common methods for material unloading include manual unloading and robotic unloading. Manual unloading is cumbersome and labor-intensive for workers; while robotic unloading can achieve automation, the equipment cost is high and maintenance is complex. Therefore, there is still room for improvement in the material unloading process of existing long plate stamping processes. Utility Model Content

[0005] The purpose of this invention is to solve the problems of cumbersome operation and high labor intensity of manual material feeding in the existing technology, while robotic material feeding can achieve automation, but the equipment cost is high and the maintenance is complicated. Therefore, a stamping material feeding device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stamping blanking device includes a blanking mechanism located on one side of a drawing station. The blanking mechanism includes a suspended and fixed guide rod, which is arranged along the width direction of the drawing station. A mounting frame is slidably connected to the guide rod. An elastic component is provided on the side of the mounting frame away from the drawing station. A second fixed pulley is rotatably connected to the mounting frame. A pull rope is wound around the second fixed pulley. One end of the pull rope is connected to a negative pressure adsorption component, and the other end is connected to a winding wheel. The winding wheel is driven by a rotary motor.

[0008] The elastic component has a first state and a second state. When the elastic component is in the first state, the negative pressure adsorption component is located directly above the material pulling station. When the elastic component is in the second state, the negative pressure adsorption component is located on one side of the material pulling station.

[0009] The elastic component includes a thrust spring and an electromagnet. The electromagnet is fixed to the guide rod, and the thrust spring is located between the electromagnet and the mounting bracket. The mounting bracket has a ferromagnetic metal that can be magnetically attracted to the electromagnet.

[0010] The mounting frame includes a support frame and a slider fixedly connected to the support frame. The slider is slidably connected to the guide rod, and the second fixed pulley is rotatably connected to the middle of the support frame.

[0011] The bottom of the support frame is fixedly connected to a limiting head, and the pull rope passes through the limiting head.

[0012] The negative pressure adsorption assembly includes a negative pressure box, which is connected to a negative pressure generating device via a flexible hose, and the bottom of the negative pressure box is provided with several suction cups.

[0013] The feeding mechanism includes a first fixed pulley, which is located on the side of the second fixed pulley away from the feeding station. The winding wheel is located directly below the first fixed pulley. The first fixed pulley is rotatably connected to the guide rod. The pull rope passes over the first fixed pulley and the second fixed pulley respectively.

[0014] The present invention proposes a stamping blanking device, which has the following advantages: the device does not require a complex robotic arm structure. It only needs to control the winding and unwinding of the winding wheel and the operation of the suction cup to complete the actions of pulling, translating, and releasing the sheet metal, thus avoiding the problem of high labor intensity in manual blanking. At the same time, it is simpler in structure and lower in cost compared to a robotic arm. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A stamping blanking device includes a blanking mechanism located on one side of the drawing station. The blanking mechanism includes a suspended and fixed guide rod 5, which is arranged along the width direction of the drawing station. A mounting frame 14 is slidably connected to the guide rod 5. An elastic component is provided on the side of the mounting frame 14 away from the drawing station. A second fixed pulley 13 is rotatably connected to the mounting frame 14. A pull rope 8 is wound on the second fixed pulley 13. One end of the pull rope 8 is connected to a negative pressure adsorption component, and the other end is connected to a winding wheel 7. The winding wheel 7 is driven by a rotary motor.

[0023] When using this stamping blanking device, refer to... Figure 3 Driven by a rotary motor, the take-up reel 7 releases the pull rope 8, causing the negative pressure adsorption assembly to move downwards with the pull rope 8. When the suction cup 9 comes into contact with the processed material, the negative pressure adsorption assembly generates a negative pressure adsorption effect, holding the material in place. Subsequently, the take-up reel 7 drives the pull rope 8 to rewind, and the pull rope 8 is pulled by the second fixed pulley 13, causing the negative pressure adsorption assembly to move upwards, lifting the material from the material pulling station. (Reference) Figure 4 When the negative pressure adsorption component moves to its limit position, the pull rope 8 is restricted from winding. At this point, as the pull rope 8 continues to wind, the mounting bracket 14 overcomes the thrust of the elastic component and slides to the left on the guide rod 5. (Refer to...) Figure 5 Then, under the control of the elastic component, the support frame 12 is positioned, and then the pull rope 8 is released. The negative pressure adsorption component moves downward, and the adsorbed board is detached, realizing the unloading action. After the unloading is completed, the winding wheel 7 continues to wind up the pull rope 8, so that the negative pressure adsorption component returns to the initial position and enters the next working cycle.

[0024] This device does not require a complex robotic arm structure. It only needs to control the winding and unwinding of the take-up wheel 7 and the operation of the suction cup to complete the actions of pulling, translating, and releasing the sheet material. This avoids the problem of high labor intensity in manual material handling. At the same time, it is simpler in structure and lower in cost compared to a robotic arm.

[0025] The elastic component has a first state and a second state. When the elastic component is in the first state, the negative pressure adsorption component is located directly above the material pulling station. The first state is so that the suction cup can be adsorbed on the board when the pull rope is released. When the elastic component is in the second state, the negative pressure adsorption component is located on one side of the material pulling station, which makes it easy to unload the board from the side of the material pulling station.

[0026] The elastic component includes a thrust spring 3 and an electromagnet 4. The electromagnet 4 is fixed to the guide rod 5, and the thrust spring 3 is located between the electromagnet 4 and the mounting bracket 14. The mounting bracket 14 has a ferromagnetic metal 2 that can be magnetically attracted to the electromagnet 4. The thrust spring 3 can reset the slider 1 to the right. (Refer to...) Figure 5 When the mounting bracket 14 is pulled to the left limit position, the electromagnet 4 is energized, so that the ferromagnetic metal 2 and the electromagnet 4 are attracted together, thereby positioning the mounting bracket 14 so that the mounting bracket 14 will not move to the right when the pull rope is released.

[0027] The mounting frame 14 includes a support frame 12 and a slider 1 fixedly connected to the support frame 12. The slider 1 is slidably connected to the guide rod 5. The second fixed pulley 13 is rotatably connected to the middle of the support frame 12. A limit head 11 is fixedly connected to the bottom of the support frame 12. A pull rope 8 passes through the limit head 11. After the pull rope pulls the negative pressure box 10 to move against the limit head 11, the limit head 11 restricts the negative pressure box 10 from continuing to move upward. The negative pressure adsorption assembly includes a negative pressure box 10. The negative pressure box 10 is connected to a negative pressure generating device through a hose. Several suction cups 9 are provided at the bottom of the negative pressure box 10. The negative pressure generating device generates suction to adsorb the plate and the suction cups 9. The negative pressure adsorption assembly can adopt the negative pressure suction cup structure in the prior art.

[0028] The feeding mechanism includes a first fixed pulley 6, which is located on the side of the second fixed pulley 13 away from the feeding station. The winding wheel 7 is located directly below the first fixed pulley 6. The first fixed pulley 6 is rotatably connected to the guide rod 5. The pull rope 8 passes around the first fixed pulley 6 and the second fixed pulley 13 respectively.

[0029] As one implementation method, refer to Figure 2 When this stamping and unloading device is running, the winding wheel 7, driven by a rotary motor, begins to release the pull rope 8. The pull rope 8 is guided by the first fixed pulley 6 and the second fixed pulley 13, driving the negative pressure box 10 to move downward. When the negative pressure box 10 descends, the suction cup 9 at its bottom contacts the surface of the processed sheet metal. Under the action of the external negative pressure generating equipment, negative pressure adsorption is generated, thereby firmly adsorbing the sheet metal.

[0030] refer to Figure 3 , Figure 4 Then, the winding wheel 7 rotates in the opposite direction to wind up the pull rope 8. The pull rope 8 is pulled by the second fixed pulley 13, causing the negative pressure box 10 and the suction cup 9 to move upward. When the negative pressure box 10 rises to the position of the limit head 11, the limit head 11 restricts the movement stroke. Under the action of the pull rope, the slider 1 slides on the guide rod 5 towards the electromagnet 4 and compresses the thrust spring 3. When the ferromagnetic metal 2 on the mounting bracket 14 comes into contact with the electromagnet 4, the electromagnet 4 is energized to generate magnetic force, attracting and fixing the ferromagnetic metal 2, thereby maintaining the current position of the negative pressure box 10.

[0031] refer to Figure 5Under the action of electromagnetic force, the pull rope 8 is released, and the negative pressure box 10 moves downward, so that the adsorbed board is released from the pulling station to complete the unloading.

[0032] Afterwards, the pull rope 8 is wound up again, and the negative pressure box 10 is pulled back to the position of the limit head 11. The power supply to the electromagnet 4 is disconnected, the ferromagnetic metal 2 is released from the adsorption, the thrust spring 3 resets and pushes the mounting bracket 14 back to the initial position, the slider 1 slides back on the guide rod 5, and the support frame 12 and the mounting bracket 14 are restored to their initial state. At this point, the negative pressure box 10 and the suction cup 9 return to the standby position above the plate, and the next round of feeding cycle begins.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
