Description

Technical Field

[0001] The present invention relates to the technical field of punching devices, and particularly to a metal plate mobile punching machine. Background Art

[0002] With the rapid development of modern industry, metal materials are increasingly widely used in many fields, such as construction, machinery manufacturing, automotive industry, aerospace, etc. As a common form of metal products, metal plates often need to be punched to meet various different engineering requirements.

[0003] According to Chinese Patent Publication No. CN221336225U, this patent relates to a rapid punching machine for metal plate production, including a punching device. One end of the punching device is movably installed with a fixing device. The punching device includes a processing table, a fixing plate, a cylinder, an adjusting plate, an adjusting cylinder, a moving plate, a control box, a lead screw, and a lead screw motor. One end of the moving plate is slidably installed at the bottom of the adjusting plate, and two numerically controlled punching ends are movably installed at both ends of the adjusting plate. The fixing device includes a placing plate, a clamping plate, a dust collection bag, a blower, and a movable block. By setting the fixing device, when punching the metal plate, the blower can blow out cold air through the air blowing pipe and the air blowing end, avoiding a large amount of dust adhering to the metal plate. At the same time, it can clean the punching debris generated during the punching of the metal plate, facilitating the metal plate to be stably placed on the top of the placing plate. The metal debris falls to the ground through the processing table, and there is no need for the staff to frequently clean the debris on the placing plate, reducing the workload of the staff. Moreover, the cold air blown out by the air blowing end can cool the numerically controlled punching ends, facilitating the numerically controlled punching ends to better complete the punching and stamping.

[0004] In the prior art, large metal plates can rely on fixtures to move on the workbench for punching. However, the large metal plate surface is in a suspended state, and each time a hole is punched, it will cause a certain degree of vibration to the metal plate, not only affecting the punching quality, but also easily damaging the drill bit. Moreover, most of the debris formed by the mobile punching of the metal plate will fall on the tabletop and the ground, making it difficult to clean and having low efficiency. Therefore, a metal plate mobile punching machine is proposed to solve the above-mentioned problems. Summary of the Invention

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a metal plate mobile drilling machine, which has the following beneficial effects:

[0020] 1. For this metal plate mobile drilling machine, high-efficiency cleaning of residual waste from drilling is adopted. The cleaning part is installed at the head of the drilling machine and includes components such as an L-shaped pressing arm, a first tooth arm, a gear, a limit frame, a second tooth arm, a compensation rod, a mounting block, and a cleaning brush. When the drill bit descends for drilling, the L-shaped pressing arm drives the first tooth arm to descend with the drill bit. The gear drives the second tooth arm to rise, so that the cleaning brush is away from the metal plate surface. After the drilling is completed and the drill bit rises, the second tooth arm descends. The compensation rod expands and contracts according to the thickness of the metal plate under the action of the first spring to avoid the mounting block squeezing and wearing the plate surface. The cleaning brush contacts the plate surface. The metal plate is horizontally moved by a linear motor, and the cleaning brush can sweep away the residual debris and powder at the drilling position and sweep the accumulated debris and powder into the blanking hopper for discharge.

[0021] 2. This metal plate mobile drilling machine adopts effective shock absorption and anti-warping to protect the metal plate and the drill bit. The shock absorption frame is set in front of the drill bit at the head of the drilling machine. The shock absorption pad at the bottom presses against the upper surface of the metal plate when the drill bit descends for drilling, preventing the surface of the plate from shaking and undulating. The shock absorption pad can undergo elastic deformation according to the thickness of the metal plate, avoiding surface wear caused by strong extrusion, protecting the drill bit at the same time, and reducing the damage to the drill bit caused by the vibration of the metal plate, which is beneficial to improving the drilling quality.

[0022] 3. This metal plate mobile drilling machine adopts a metal plate support and clamping method. The suspended part of the metal plate is supported by two worktables, without shaking and bending, improving the stress state of the metal plate. Insert one side of the metal plate into the inner wall of the L-shaped clamp, and drive the upper clamp to lift by an electric push rod to clamp metal plates of different sizes. Moreover, the L-shaped clamp and the bottom of the cross beam are fitted with the inner wall of the clamp groove of the worktable, and the top surface of the front end of the L-shaped clamp is flush with the top surface of the worktable, ensuring stable contact between the bottom surface of the metal plate and the worktable, guaranteeing the stability and safety of the drilling operation.

[0023] 4. This metal plate mobile drilling machine adopts the cooperation of the material discharge part and related components. The material discharge part includes an adjusting arm, an L-shaped lifting arm, a connecting arm, a guide plate, a sliding rod, a feeding hopper, etc. When the drill bit descends for drilling, the L-shaped pressing arm squeezes the adjusting arm through an inclined plane. The adjusting arm drives the slider to move and squeezes the L-shaped lifting arm, so that the connecting arm pushes the guide plate to rise. The L-shaped lifting arm enters the guiding groove. The higher side of the guide plate abuts against the outer wall of the lower hopper mouth of the feeding hopper and pushes the feeding hopper to rise, making the upper hopper mouth of the feeding hopper fit the lower surface of the metal plate, and the hole position below is in a blocked and closed state, avoiding the sputtering of debris and powder. The debris and powder slide along the guide plate to the outside of the equipment after passing through the feeding hopper for convenient centralized recovery. This process realizes the centralized collection and guiding discharge of debris and powder, reducing the pollution of the tabletop and the equipment and the subsequent cleaning difficulty.

[0024] 5. This metal plate mobile drilling machine adopts self-adaptation to different sizes of metal plates for processing to improve the processing quality. The compensation rod of the material cleaning part elastically expands and contracts through spring one to adapt to metal plates of different thicknesses. The electric push rod of the mobile feeding part can clamp metal plates of different sizes. The slider of the installation part is elastically connected through spring two to adapt to different situations. The relevant structures of the material discharge part can also be automatically adjusted according to the change of the metal plate size. These designs enable the equipment to perform self-adaptive matching according to different sizes of metal plates, improving the processing stability, avoiding damage to the upper and lower surfaces of the metal plate, and further improving the processing quality. At the same time, during the repeated drilling of the drill bit, the debris and dust on the upper and lower surfaces of the metal plate can be uniformly collected and guided out, improving the cleaning efficiency, reducing the pressure and difficulty of manual cleaning. After the large metal plate is clamped, the supporting force can be effectively improved through the two side worktables, reducing the bending stress of the suspended part, and avoiding the hidden danger of bending deformation caused by internal tensile stress and compressive stress.

[0035] 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.

[0036] Please refer to Figures 1-9 , the present invention provides a technical solution: a metal plate mobile punching machine, including a punching machine head 1. The cleaning part 2 of this case is installed on the punching machine head 1 and is used to clean the residual waste after punching for metal plates of different sizes adaptively. The shock-absorbing frame 3 of this case is arranged on the punching machine head 1 and is used to perform punching shock absorption and anti-warping for metal plates of different sizes adaptively. The mobile feeding part 4 of this case is installed at the bottom of the punching machine head 1 and is used to clamp and move the metal plate for continuous punching operations. The installation part 5 of this case is installed at the bottom of the mobile feeding part 4 and is used to install the discharging tool. The discharging part 6 of this case is installed on the installation part 5 and is used to guide and discharge the punching blanking for metal plates of different sizes adaptively. The bracket 7 of this case is installed on the installation part 5 and is used to install and support the working platform. The supporting part 8 of this case is installed on the bracket 7 and is used to support large metal plates for stable movement.

[0037] In the present invention, in order to further clean the scraps remaining on the surface of the metal plate after punching, the cleaning part 2 of this case includes an L-shaped pressing arm 21. One end of the L-shaped pressing arm 21 is fixedly connected to the side wall of the drill bit of the punching machine head 1. A first toothed arm 22 is fixedly connected to the top of one end of the L-shaped pressing arm 21. A gear 23 is rotatably connected to the side wall of the punching machine head 1. A limiting frame 24 is fixedly connected to the side wall of the punching machine head 1. A second toothed arm 25 is slidably connected to the inner wall of the limiting frame 24. A limiting plate is fixedly connected to the top end of the second toothed arm 25, and the limiting plate can prevent the second toothed arm 25 from slipping out of the limiting frame 24. The gear 23 meshes with the first toothed arm 22 and the second toothed arm 25 respectively. A compensation rod 26 slidably penetrates through the bottom end of the second toothed arm 25. A mounting block 27 is fixedly connected to the bottom end of the compensation rod 26. A first spring is elastically connected between the mounting block 27 and the second toothed arm 25. The compensation rod 26 elastically expands and contracts through the first spring to adapt to metal plates of different thicknesses. A cleaning brush 28 is installed on the side wall of the mounting block 27, and the cleaning brush 28 can centrally scrape the residual debris on the plate surface during the movement of the metal plate. The number of the cleaning parts 2 of this case is two, and the other cleaning part 2 is installed on the other side of the punching machine head 1. The two cleaning parts 2 are symmetrically arranged with each other.

[0038] In this embodiment, in order to clamp and move metal plates of different sizes, the moving and feeding unit 4 of this case includes a punching machine body 41, which is fixedly installed at the rear side of the bottom of the punching machine head 1. Two hydraulic rods 42 are installed on the front surface of the punching machine body 41. The Y-axis movement of the metal plate is realized by the telescopic movement of the hydraulic rods 42. The inner rod ends of the two hydraulic rods 42 are fixedly connected with a cross beam 43. A linear motor 44 is installed on the front surface of the cross beam 43. The X-axis movement of the metal plate is realized by the sliding of the mover end of the linear motor 44. An L-shaped clamp 45 is installed on the mover end of the linear motor 44. An upper clamp 46 is slidably connected to the inner wall of the L-shaped clamp 45. An electric push rod is installed between the upper clamp 46 and the L-shaped clamp 45. The upper clamp 46 is driven to lift by the telescopic movement of the electric push rod to clamp metal plates of different sizes. In order to install a specific discharging tool, the installation unit 5 of this case includes a punching machine base 51. The rear side of the top of the punching machine base 51 is fixedly connected with the punching machine body 41. Sliding grooves 52 are opened on both sides of the punching machine base 51. Sliding blocks 53 are slidably connected to the inner walls of the two sliding grooves 52. A second spring 54 is elastically connected between each sliding block 53 and the inner wall of the corresponding sliding groove 52. An inclined groove 55 is opened on the front side of the top of the punching machine base 51. An adjustment groove 56 is opened on the inclined surface of the inner wall of the inclined groove 55. The shock absorber 3 is installed on the front surface of the drill bit of the punching machine head 1. A shock absorbing pad is fixedly connected to the bottom of the shock absorber 3. The shock absorbing pad contacts the metal plate surface elastically for shock absorption and buffering. There are two supports 7, and both of the two supports 7 are installed on the punching machine base 51.

[0039] It should be noted that, in order to collect the debris under the holes of the metal plate, the discharging unit 6 of this case includes two adjusting arms 61, which are respectively installed on the two sliding blocks 53. L-shaped lifting arms 62 are arranged at one ends of the two adjusting arms 61. A connecting arm 63 is fixedly connected between the tops of the two L-shaped lifting arms 62. The connecting arm 63 is slidably connected to the inner wall of the adjustment groove 56. A guide plate 64 is fixedly connected to the connecting arm 63. The guide plate 64 is attached to the inner wall of the inclined groove 55. Four sliding rods 65 penetrate through the front side of the top of the punching machine base 51 in a sliding manner. A feeding hopper 66 is fixedly connected to the tops of the four sliding rods 65. Pulling springs are elastically connected between the four corners of the outer wall of the feeding hopper 66 and the top of the punching machine base 51. The elastic force of the pulling springs causes the feeding hopper 66 to reset downward. The bottom ends of the two L-shaped pressing arms 21, the two ends of the two adjusting arms 61, and the rear ends of the two L-shaped lifting arms 62 are all inclined plane structures. The inclined planes of the two L-shaped pressing arms 21 are respectively attached to the inclined planes of the adjacent ends of the two adjusting arms 61. The inclined planes of the other ends of the two adjusting arms 61 are respectively attached to the inclined planes of the two L-shaped lifting arms 62.

[0040] It is worth noting that the two brackets 7 are both U-shaped structures, and the support part 8 includes two workbenches 81, which are symmetrically installed on the ear ends on both sides of the two brackets 7. The bottom of the two workbenches 81 on the side close to each other is provided with a guide groove 82 corresponding to the L-shaped lifting arm 62. After rising, the L-shaped lifting arm 62 will slide along the inner wall of the guide groove 82, and will not cause obstruction and jamming problems. The top rear side of the two workbenches 81 is provided with a clamp groove 83, and the bottom of the beam 43 is in contact with the bottom of the inner wall of the two clamp grooves 83. The bottom of the L-shaped clamp 45 is in contact with the inner wall of the two clamp grooves 83. The front end top surface of the L-shaped clamp 45 is flush with the top surface of the two workbenches 81. The flush setting can always ensure that the bottom surface of the metal plate is in contact with the workbench 81 and is stably supported.

[0041] Working principle: In this case, the punch head 1, the punch body 41 and the punch base 51 form a complete punching equipment. The punch head 1 uses the existing hydraulic system to provide power to punch the drill bit into the metal plate to form a hole. The hydraulic system drives the drill bit to rise and fall, thereby driving the cleaning part 2 to rise and fall and adjust. One side of the metal plate is inserted into the inner wall of the L-shaped clamp 45, and the upper clamp 46 is driven down by the contraction of the electric push rod to clamp the metal plate. The suspended part of the metal plate is supported by the two workbenches 81, and will not shake or bend, thereby increasing the force on the metal plate and ensuring the stability and safety of the punching operation. The two workbenches 81 are isolated to form a punching area. The metal plate is freely adjusted to the position where the hole needs to be punched through the operation of the hydraulic rod 42 and the linear motor 44. Each punching is only performed within the punching area. Only the metal plate surface between the punching areas is in a suspended state and will not affect the drill bit from penetrating the plate body.

[0042] When the drill bit descends through the hydraulic system, the shock-absorbing frame 3 follows and drives the shock-absorbing pad to press the upper surface of the metal plate to prevent the plate surface from shaking and fluctuating. The shock-absorbing pad can also elastically deform according to the thickness of the metal plate to avoid strong extrusion causing wear on the plate surface. At the same time, the L-shaped pressure arm 21 drives the tooth arm 1 22 to follow the drill bit down, thereby driving the tooth arm 2 25 to rise through the gear 23, so that the cleaning brush 28 is away from the metal plate surface.

[0043] When a drilling is completed, the drill bit rises, and the tooth arm 25 descends to drive the compensation rod 26 and perform telescopic compensation according to the thickness of the current plate surface under the elasticity of the spring 1, thereby avoiding the mounting block 27 from causing extrusion and wear on the plate surface. The bristles of the cleaning brush 28 contact the plate surface and drive the metal plate to move horizontally to the left or right through the linear motor, prompting the bristles to sweep away the residual debris and powder at the punching position. When the metal plate moves to the left or right to the end of the linear motor 44, one side of the metal plate will move away from the punching area, so that the cleaning brush 28 can sweep the accumulated debris and powder into the lower hopper 66 below for discharge.

[0044] While the drill bit descends for drilling, the L-shaped pressing arm 21 squeezes the inclined surface of the adjusting arm 61 through the inclined surface, prompting the adjusting arm 61 to drive the slider 53 to move within the sliding groove 52. At the same time, the inclined surface at the other end of the adjusting arm 61 squeezes the L-shaped lifting arm 62, prompting the connecting arm 63 to rise along the adjusting groove 56 and push the material guiding plate 64. After the L-shaped lifting arm 62 rises, it enters the guiding groove 82 without deviation or dislocation. After the material guiding plate 64 rises, the higher side abuts against the outer wall of the lower hopper opening of the feeding hopper 66 and pushes the feeding hopper 66 to rise linearly, so as to prompt the upper hopper opening of the feeding hopper 66 to fit the lower surface of the metal plate. When the drill bit drills a hole, the area below the hole position is in a shielded and closed state, avoiding the sputtering of debris powder from below, ensuring the concentration of debris powder recovery, reducing the pollution of the table and equipment by debris powder and the subsequent cleaning difficulty. The debris powder passes through the feeding hopper 66 and then slides along the material guiding plate 64 to the outside of the equipment, facilitating centralized recovery.

[0045] After the drill bit rises, the L-shaped pressing arm 21 rises. At this time, the adjusting arm 61 loses the extrusion force, and the slider 53 is pushed to reset by the elastic force of the second spring 54. Furthermore, the L-shaped lifting arm 62 loses the extrusion force. At the same time, the pulling force of the tension spring rotates the feeding hopper 66 downward to move away from the lower surface of the metal plate. The sliding rod 65 is used to limit the feeding hopper 66 to ensure the stability of the lifting of the feeding hopper 66. The feeding hopper 66 descends and pushes the material guiding plate 64 to descend and reset to the inclined groove 55. At the same time, the connecting arm 63 resets to the adjusting groove 56, and the L-shaped lifting arm 62 moves away from the guiding groove 82. The actual effect of this method is that after the drill bit moves away from the metal plate surface, when the metal plate moves through the linear motor 44 and the hydraulic rod 42, the feeding hopper 66 does not abut against the lower surface of the metal plate, so as not to cause the problem of abrasion and scratching of the lower surface of the metal plate during movement, further improving the safety of the movement of the metal plate.

[0046] This case uses the first spring, the second spring 54 and the tension spring to drive the connected structures, which can be adaptively matched according to metal plates of different sizes, improve the processing stability, and avoid damage to the upper and lower surfaces of the metal plate, further improving the processing quality. During the repeated drilling of the drill bit, the debris and dust on the upper and lower surfaces of the metal plate can be uniformly collected and guided out, improving the cleaning efficiency, and further reducing the pressure and difficulty of manual cleaning. After the large metal plate is clamped, the supporting force can be effectively improved by the workbenches 81 on both sides, and at the same time, the bending stress of the suspended part is reduced, avoiding the hidden danger of bending deformation caused by the internal tensile stress and compressive stress of the suspended part of the large metal plate, and improving the processing quality.
