A high-precision punching and grinding device based on metal plate processing

Abstract

The present invention relates to the technical field of processing machine tools, and discloses a high-precision punching and grinding device based on metal plate processing. The metal plate first moves to the lower part of the punching head and stops moving. The punching head moves downward and rotates, and the punching head is used to punch the metal plate. Then, after the metal plate moves to the lower part of the grinding belt and stops moving, the grinding belt grinds the punching position of the metal plate. When the punching head needs to change the specification, the punching head moves upward to the placement plate. After the punching head abuts against the placement plate, the punching mechanism removes the punching head to leave the punching head on the placement plate. Then, the placement plate deflects, and the punching heads of other specifications on the placement plate are installed by the punching mechanism again, so that the punching mechanism completes the replacement of the punching head specification. Therefore, when continuously producing a metal plate processing production line, the punching specification can be changed during the production process, avoiding a large amount of time waste caused by the shutdown of the production line and improving the production efficiency of the punching and grinding device.

Description

Technical Field

[0001] The present invention relates to the technical field of processing machine tools, and particularly to a high-precision punching and grinding device based on metal plate processing. Background Art

[0002] Punching processing refers to punching various patterns on materials such as steel plates, leather, cloth, wooden boards, etc. to meet different requirements.

[0003] In the existing punching and grinding devices, such as Chinese Patent Application CN116900162A, the punching assembly can perform punching on the I-shaped metal plate. At the same time, under the driving action of the stepping movement assembly, the translation frame can move step by step relative to the support table, realizing the automatic equal-spacing adjustment of the punching head position. After the punching head moves a certain distance, the I-shaped metal plate is vertically punched once, greatly improving the punching processing efficiency and automation degree of the I-shaped metal plate; and through the bracket set, it can move towards and away from the punching head alternately under the action of the transmission assembly. When the punching head is performing punching operations, the bearing block I on the bracket can support the I-shaped metal plate, ensuring the stable support of the opening area of the I-shaped metal plate and preventing the punching area of the I-shaped metal plate from deforming, greatly ensuring the punching quality of the I-shaped metal plate. The grinding plate set can slide relative to the I-shaped metal plate under the transmission action of the sliding assembly, realizing the effect of grinding and deburring the punched I-shaped metal plate, and greatly improving the punching quality of the I-shaped metal plate.

[0004] However, there are still the following problems: When the punching and grinding device punches the metal plate, the processed hole diameters are not single. When it is necessary to change the processing specifications, currently, the processing head needs to be replaced by stopping the machine, resulting in a low processing efficiency of the punching and grinding device.

[0018] Compared with the prior art, the present invention provides a high-precision punching and grinding device based on metal plate processing, which has the following beneficial effects:

[0019] 1. For the high-precision punching and grinding device based on metal plate processing, the metal plate is sent to the conveyor belt, and the conveyor belt drives the metal plate to move in the machine body. The metal plate first moves to the lower part of the punching head and stops moving. The punching head moves down and rotates, and the punching head is used to punch the metal plate. Then the punching head returns to its original position, and the metal plate moves again on the conveyor belt. After the metal plate moves to the lower part of the grinding belt, it stops moving, and the grinding belt grinds the punching position of the metal plate. Then the conveyor belt drives the metal plate to move out of the machine body. When the punching head needs to change the specification, the punching head stops rotating, the punching head moves towards the placement plate, and after the punching head abuts against the placement plate, the punching mechanism removes the punching head to leave the punching head on the placement plate. Then the placement plate deflects, and other specification punching heads on the placement plate are installed by the punching mechanism again, so that the punching mechanism completes the replacement of the punching head specification. Therefore, when continuously producing the metal plate processing production line, the punching specification can be changed during the production process, avoiding a large amount of time waste caused by the production line shutdown and improving the production efficiency of the punching and grinding device.

[0020] 2. For the high-precision punching and grinding device based on metal plate processing, through the setting of the ratchet teeth and the positioning rod, the placement plate can only rotate in one direction even when subjected to an external force, avoiding the running failure of the punching and grinding device caused by the reverse rotation of the placement plate due to the thrust when the punching head abuts into the accommodating opening of the placement plate, and improving the operation stability of the device.

[0021] 3. For the high-precision punching and grinding device based on metal plate processing, through the setting of the brush arm, after the punching process, the surface of the metal plate is cleaned by the brush arm on the metal plate, avoiding the influence of debris on the metal plate on the quality of the grinding process, improving the service life of the grinding belt, and reducing the use cost of the device.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a high-precision punching and grinding device based on metal plate processing.

[0033] Embodiment 1

[0034] In a typical implementation manner of the present application, as Figure 1As shown in the figure, a high-precision punching and grinding device based on metal plate processing includes a machine body 1, a grinding mechanism 2 arranged on the machine body 1, and a punching mechanism 3 arranged on the machine body 1. The grinding mechanism 2 includes a conveyor belt 21 and a grinding belt 25. The conveyor belt 21 is arranged on the machine body 1 and penetrates through the machine body 1. The adjacent part above the conveyor belt 21 on the machine body 1 is an open end, so that the metal plate conveyed on the conveyor belt 21 passes through the wall surface of the machine body 1. A grinding belt 25 is arranged inside the machine body 1. The grinding belt 25 is located above the conveyor belt 21, and the bottom end of the grinding belt 25 is adjacent to the conveyor belt 21. The grinding belt 25 is used for grinding the metal plate on the conveyor belt 21;

[0035] The punching mechanism 3 includes a punching head 38 and a placement plate 310. The punching head 38 is arranged on the machine body 1. The punching head 38 is located above the conveyor belt 21 and in front of the conveying direction of the conveyor belt 21. The grinding belt 25 is located behind the conveying direction of the conveyor belt 21. The punching head 38 is used for punching the metal plate on the conveyor belt 21. A placement plate 310 is arranged inside the machine body 1. The placement plate 310 is at the same height as the punching head 38. The placement plate 310 is used for placing punching heads 38 of different specifications;

[0036] When changing the specification of the punching head 38, the in-use punching head 38 abuts against the placement plate 310, and the in-use punching head 38 is unloaded onto the placement plate 310. After the placement plate 310 deflects, the spare punching head 38 on the placement plate 310 is used.

[0037] When using the present invention:

[0038] The metal plate is sent onto the conveyor belt 21, and the conveyor belt 21 drives the metal plate to move inside the machine body 1. The metal plate first moves to the lower part of the punching head 38 and stops moving. The punching head 38 moves downwards and rotates self - sufficiently, and the punching head 38 is used to punch the metal plate. Then the punching head 38 resets. The metal plate moves again on the conveyor belt 21. After the metal plate moves to the lower part of the grinding belt 25, it stops moving. The grinding belt 25 grinds the punching position of the metal plate. Then the conveyor belt 21 drives the metal plate to move out of the machine body 1. When the specification of the punching head 38 needs to be changed, the punching head 38 stops rotating self - sufficiently, the punching head 38 moves towards the placement plate 310. After the punching head 38 abuts against the placement plate 310, the punching mechanism 3 unloads the punching head 38 to leave the punching head 38 on the placement plate 310. Then the placement plate 310 deflects, and the punching mechanism 3 installs other - specification punching heads 38 on the placement plate 310 again. Thus, the punching mechanism 3 completes the replacement of the punching head 38 specification. Therefore, when continuously producing a metal plate processing production line, the punching specification can be changed during the production process, avoiding a large amount of time waste caused by the production line shutdown and improving the production efficiency of the punching and grinding device.

[0039] Embodiment 2

[0040] As Figures 2 - 4 shown, the difference from the above embodiment is that the grinding mechanism 2 further includes a conveying motor 22. The conveying motor 22 is fixedly installed on the body 1. The conveying motor 22 is power-connected to the conveyor belt 21. A load-bearing plate is arranged in the inner ring of the conveyor belt 21. The load-bearing plate is fixedly connected to the inner side wall of the body 1. The load-bearing plate is adjacent to the bottom end of the top surface of the conveyor belt 21. Conveyor roller frames 23 are arranged on both sides of the body 1. The conveyor roller frames 23 are adjacent to the body 1. The conveying ends of the conveyor roller frames 23 are at the same height as the conveyor belt 21. The width of the conveyor roller frames 23 is adapted to the width of the conveyor belt 21. The conveyor roller frames 23 are used to transfer metal plates.

[0041] Among them, when conveying the metal plate, the metal plate is first transferred on the conveyor roller frame 23. After the metal plate is transferred into the body 1, the metal plate will be placed on the conveyor belt 21. The conveying motor 22 is started, and the conveying motor 22 drives the conveyor belt 21 to rotate, so that the metal plate moves on the conveyor belt 21.

[0042] Furthermore, two shaft rollers 24 are rotatably fitted in the body 1. The shaft rollers 24 are opposite up and down. A grinding belt 25 is tensioned on the shaft rollers 24. A grinding motor 26 is fixedly installed in the body 1. Belt pulleys 27 are fixedly installed on the shaft of the grinding motor 26 and on the shaft of the bottom shaft roller 24. The belt pulleys 27 are opposite up and down. A belt 28 is tensioned on the belt pulleys 27.

[0043] Among them, when performing grinding treatment, the grinding motor 26 is started. The grinding motor 26 drives one belt pulley 27 to rotate. One belt pulley 27 drives the belt 28 to rotate. The belt 28 drives the other belt pulley 27 to rotate. The other belt pulley 27 drives the shaft roller 24 to rotate. The shaft roller 24 drives the grinding belt 25 to rotate, so that the grinding belt 25 performs grinding treatment on the metal plate.

[0044] Furthermore, a plurality of limiting rollers 29 are fixedly installed in the body 1. The limiting rollers 29 are symmetrically distributed below the grinding belt 25 and the punching head 38. The limiting rollers 29 are located above the conveyor belt 21. The limiting rollers 29 are all adjacent to the conveyor belt 21. The limiting rollers 29 are used to limit the metal plate on the conveyor belt 21.

[0045] Among them, when conveying the metal plate, the metal plate will enter between the conveyor belt 21 and the limiting rollers 29. The limiting rollers 29 play a role in limiting the metal plate, avoiding the metal plate from shifting due to external forces during processing, ensuring accurate positioning of the metal plate at the processing position, and improving the accuracy of punching and grinding treatment.

[0046] Embodiment 3

[0047] As Figures 5 - 8As shown, the difference from the above embodiment is that the punching mechanism 3 further includes a slide rail 31, which is fixedly installed at the inner top end of the machine body 1. A sliding member 32 is slidably engaged with the slide rail 31. A screw rod 33 is rotatably engaged with the inner top end of the machine body 1. The screw rod 33 passes through the sliding member 32 and is in threaded engagement with the sliding member 32. The lengths of the slide rail 31 and the screw rod 33 are adapted to the width of the conveyor belt 21. A stepping motor 34 is fixedly installed at the inner top end of the machine body 1, and the stepping motor 34 is in power connection with the screw rod 33.

[0048] Further, a hydraulic rod 35 is fixedly installed at the bottom end of the sliding member 32. The telescopic end of the hydraulic rod 35 faces downward. A punching motor 36 is fixedly installed on the extending rod of the hydraulic rod 35. A gripper 37 is fixedly installed on the shaft of the punching motor 36. A punching head 38 is clamped and fixed on the gripper 37.

[0049] Among them, when punching is performed, the stepping motor 34 is started. The stepping motor 34 drives the screw rod 33 to rotate. The screw rod 33 drives the sliding member 32 to move on the slide rail 31. The sliding member 32 drives the hydraulic rod 35 to move. The hydraulic rod 35 is started. The hydraulic rod 35 drives the punching motor 36 to move downward. The punching motor 36 is started to drive the gripper 37 to rotate and move downward. The gripper 37 drives the punching head 38 to move downward and rotate, so that the punching head 38 punches the metal plate.

[0050] Further, a servo motor 39 is fixedly installed on the inner side wall of the machine body 1. The servo motor 39 is located on the moving track of the punching head 38. A placing disc 310 is fixedly installed on the shaft of the servo motor 39. A positioning clamping arm 311 is rotatably engaged with the placing disc 310. The positioning clamping arm 311 is used to fix the punching head 38 on the placing disc 310. A rotating arm cylinder 312 is fixedly installed on the placing disc 310, and the rotating arm cylinder 312 is in power connection with the positioning clamping arm 311.

[0051] Further, a plurality of accommodating openings are provided on the placing disc 310. The accommodating openings are evenly distributed in a circular shape on the placing disc 310. The accommodating openings are adapted to the cross-sectional dimensions of the punching head 38. The positioning clamping arms 311 are symmetrically distributed in two parts on both sides of the accommodating opening. The positioning clamping arms 311 on both sides are meshed with each other through teeth and are power-connected. A plurality of positioning clamping arms 311 are respectively adapted to each accommodating opening.

[0052] Further, a fixing frame 313 is fixedly installed on the inner side wall of the machine body 1. The fixing frame 313 is at the same height as the placing tray 310 and adjacent to the placing tray 310. A ratchet 314 is rotatably fitted on the fixing frame 313. The ratchet 314 is adjacent to the top surface of the placing tray 310. The length of the ratchet 314 extends above the placing tray 310. A torsion spring 315 is sleeved on the shaft of the ratchet 314. One end of the torsion spring 315 is connected to the ratchet 314, and the other end of the torsion spring 315 is connected to the fixing frame 313. A plurality of limiting rods 316 are fixedly installed on the top surface of the placing tray 310. The limiting rods 316 are evenly distributed in a circular shape and are respectively located between adjacent accommodating openings. The position of the ratchet 314 covers the rotation trajectory of the limiting rods 316, and the rotation direction of the ratchet 314 is opposite to the rotation direction of the limiting rods 316.

[0053] Among them, when replacing the specification of the punching head 38, stop the operation of the punching motor 36, drive the punching head 38 to move into the accommodating opening of the placing tray 310. After the punching head 38 reaches the inside of the accommodating opening, the gripper 37 releases the clamping and fixing of the punching head 38. When the punching head 38 reaches the inside of the accommodating opening, the thrust of the punching head 38 causes the placing tray 310 to drive the positioning rod 316 to abut against the ratchet 314. Due to the opposite rotation directions of the ratchet 314 and the placing tray 310, the placing tray 310 will be blocked by the ratchet 314 and cannot rotate in reverse, thereby ensuring the stability of the operation of the placing tray 310. Then start the servo motor 39. The servo motor 39 drives the placing tray 310 to deflect and then stops operating, so that the spare punching head 38 rotates to the lower part of the gripper 37. The gripper 37 clamps and fixes the spare punching head 38 again, thus completing the replacement of the specification of the punching head 38.

[0054] Further, an electric control translation table 317 is fixedly installed on the inner side wall of the machine body 1. The length of the electric control translation table 317 is greater than the width of the conveyor belt 21. A brush arm 318 is fixedly installed on the moving table of the electric control translation table 317. The brush arm 318 is located above the conveyor belt 21 and adjacent to the conveyor belt 21.

[0055] Among them, start the electric control translation table 317. The electric control translation table 317 drives the brush arm 318 to reciprocate, so that the brush arm 318 sweeps the surface of the metal plate after punching treatment to avoid debris on the metal plate.

[0056] The overall working principle of the punching and grinding device:

[0057] The metal plate is sent onto the conveyor belt 21, and the conveyor belt 21 drives the metal plate to move within the machine body 1. The metal plate first moves to a position below the punching head 38 and stops moving. The punching head 38 moves downward and rotates, and the punching head 38 is used to punch the metal plate. Then the punching head 38 resets, and the metal plate moves again on the conveyor belt 21. After the metal plate moves below the grinding belt 25, it stops moving. The grinding belt 25 grinds the punching position of the metal plate. Then the conveyor belt 21 drives the metal plate to move out of the machine body 1. When the punching head 38 needs to change the specification, the punching head 38 stops rotating, and the punching head 38 moves towards the placement tray 310. After the punching head 38 abuts against the placement tray 310, the punching mechanism 3 removes the punching head 38 to leave the punching head 38 on the placement tray 310. Then the placement tray 310 deflects, and the punching heads 38 of other specifications on the placement tray 310 are installed again by the punching mechanism 3;

[0058] Among them, when conveying the metal plate, the metal plate first moves on the conveying roller frame 23. After the metal plate is conveyed into the machine body 1, the metal plate is placed on the conveyor belt 21. The conveying motor 22 is started, and the conveying motor 22 drives the conveyor belt 21 to rotate, so that the metal plate moves on the conveyor belt 21;

[0059] When performing the grinding treatment, the grinding motor 26 is started. The grinding motor 26 drives a pulley 27 to rotate. One pulley 27 drives the belt 28 to rotate. The belt 28 drives another pulley 27 to rotate. Another pulley 27 drives the shaft roller 24 to rotate. The shaft roller 24 drives the grinding belt 25 to rotate, so that the grinding belt 25 grinds the metal plate;

[0060] When conveying the metal plate, the metal plate enters between the conveyor belt 21 and the limiting roller 29. The limiting roller 29 plays a role in limiting the metal plate, avoiding the metal plate from shifting due to external forces during processing, ensuring the accurate positioning of the metal plate at the processing position, and improving the accuracy of punching and grinding;

[0061] When performing the punching treatment, the stepping motor 34 is started. The stepping motor 34 drives the screw 33 to rotate. The screw 33 drives the sliding member 32 to move on the slide rail 31. The sliding member 32 drives the hydraulic rod 35 to move. The hydraulic rod 35 is started. The hydraulic rod 35 drives the punching motor 36 to move downward. The punching motor 36 is started to drive the gripper 37 to rotate and move downward. The gripper 37 drives the punching head 38 to move downward and rotate, so that the punching head 38 punches the metal plate;

[0062] When replacing the specifications of the punching head 38, stop the operation of the punching motor 36, drive the punching head 38 to move into the accommodating opening of the placement disk 310. After the punching head 38 reaches the inside of the accommodating opening, the gripper 37 releases the clamping and fixing of the punching head 38. When the punching head 38 reaches the inside of the accommodating opening, the thrust of the punching head 38 causes the placement disk 310 to drive the positioning rod 316 to abut against the ratchet 314. Due to the fact that the rotation direction of the ratchet 314 is opposite to that of the placement disk 310, the placement disk 310 will be blocked by the ratchet 314 and cannot rotate in reverse, thereby ensuring the stability of the operation of the placement disk 310. Then, start the servo motor 39. The servo motor 39 drives the placement disk 310 to deflect and then stops operating, so that the spare punching head 38 rotates to the lower part of the gripper 37. The gripper 37 clamps and fixes the spare punching head 38 again, thus completing the replacement of the specifications of the punching head 38;

[0063] Moreover, start the electric control translation stage 317. The electric control translation stage 317 drives the brush arm 318 to reciprocate, so that the brush arm 318 cleans the surface of the metal plate after punching treatment, avoiding the existence of debris on the metal plate.

[0064] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
