Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular to a high-speed punching device on the surface of a metal plate. Background Art

[0002] Metal perforated plate is also known as perforated mesh, porous plate, perforated plate, mining screen, machine screen, etc. As the name implies, it refers to metal plates with various shapes of holes on the surface. The products are widely used in chemical machinery, pharmaceutical equipment, food and beverage machinery, cigarette machinery and other industries. Such mesh plates are usually punched by punching knives at high speed during the manufacturing process to achieve rapid punching. In order to improve the stability of the metal plate during the punching process and prevent the plate from jumping and warping during the punching process, the base is generally used to support the mesh plate. The tool directly punches the waste into the discharge port during the punching process;

[0003] At present, the diameter of the discharge port of the support base is roughly the same as the diameter of the stamping tool. This can effectively ensure the punching quality and reduce the deformation of the hole edge. However, the waste punched out of the metal plate is very easy to get stuck in the discharge port and cannot be discharged smoothly, which will seriously affect the normal processing operation. In addition, the position of this type of tool holder is generally fixed. When the plate moves and the punching position is changed, the bottom surface of the plate will wear between the tool holder, affecting the surface quality of the plate. In severe cases, the plate may be damaged and deformed after moving due to burrs and protrusions.

[0019] The present invention can directly drive the docking assembly to rotate through a servo motor, wherein the rotating disk can directly push the connecting sliding pin and the contact seat to move through the inclined sliding groove during the rotation process, thereby realizing the relative expansion operation of the six groups of contact seats. Since the six groups of contact seats form a blanking knife groove when docking, under normal circumstances, the stamping knife seat and the blanking knife groove are docked to achieve better punching operation.

[0021] The present invention arranges rolling teeth on one side of the servo motor output shaft close to the meshing teeth. Under normal circumstances, the drive of the servo motor will drive the movable frame to move up and down above the sliding base until the movable frame is docked with the sliding base.

The rocker arm is pulled by the pulling pin to achieve the separation between the meshing groove and the meshing teeth, and the electromagnetic pull rod in the docking assembly also pushes the bevel gear groups to separate from each other. At this time, the rotation effect of the servo motor will drive the overall longitudinal position movement of the movable base assembly through the meshing effect between the rolling teeth and the base meshing plate, change the docking position of the bearing assembly, and cooperate with the stamping tool holder to punch holes at different positions on the surface of the processed blank, effectively improving the degree of automation and integration of the equipment.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0035] refer to Figure 1-8 , including a machine table 1, a workpiece 4 is mounted on the surface of the machine table 1 through a transverse driving component 2, the transverse driving component 2 drives the workpiece 4 to move transversely above the machine table 1, a punching tool holder 5 is movably arranged above the machine table 1 through a sliding beam, the punching tool holder 5 moves longitudinally above the workpiece 4, a movable base component 6 is arranged below the workpiece 4, the movable base component 6 includes a sliding base 61 and a movable frame 62, the movable frame 62 is slidably arranged above the sliding base 61 through a sliding rod, the movable base component 6 moves longitudinally on the surface of the machine table 1 through a transmission mechanism 8, and a chip removal plate 3 is provided below the machine table 1 near the sliding base 61;

[0036] The transmission mechanism 8 includes two groups of servo motors 81 and a docking assembly 85. The servo motor 81 is connected to the docking assembly 85 through a bevel gear group 84. The servo motor 81 is fixed to the side of the movable frame 62. The output shaft of the servo motor 81 is fixed with a bite tooth 96. The bite tooth 96 is meshed with a meshing groove 95 on one side of the swing rod 92. The servo motor 81 drives the movable frame 62 to slide up and down above the sliding base 61 through the meshing effect of the bite tooth 96 and the meshing groove 95.

[0037] The bearing assembly 7 is composed of six groups of abutment seats 71 distributed in a circular array, and a blanking knife groove 72 is formed at the center of the circle of the six groups of abutment seats 71. The six groups of abutment seats 71 are all movably arranged on the inner side of the movable frame 62 through the docking assembly 85, and the top surface horizontal height of the abutment seat 71 is greater than the top surface horizontal height of the movable frame 62.

[0038] In this embodiment, the effect of the lateral driving component 2 driving the processed blank 4 to move horizontally on the surface of the machine table 1 changes the actual horizontal opening position of the processed blank 4. After the processed blank 4 is moved to the specified position, the punching tool holder 5 above the machine table 1 can achieve a change in longitudinal position, thereby meeting the hole opening effect at different positions on the surface of the processed blank 4. At the same time, the movable base component 6 can also move longitudinally under the processed blank 4 through the transmission mechanism 8, thereby cooperating with the punching tool holder 5 to achieve docking, meeting the effect of higher processing quality.

[0039] Furthermore, after being driven, the servo motor 81 can directly drive the docking assembly 85 to rotate. The rotation effect of the docking assembly 85 will drive the six groups of abutment seats 71 to expand and close in the movable frame 62. When the six groups of abutment seats 71 are docked and closed, a blanking knife groove 72 will be formed at the center position of the six groups of abutment seats 71. With the stamping of the stamping knife seat 5, a better punching operation can be achieved, and the punching quality can be effectively guaranteed. When the six groups of abutment seats 71 are expanded, the blanking knife groove 72 is decomposed, and the waste material inside it will fall normally at this time, preventing the waste material from being stuck in the blanking knife groove 72 and affecting the subsequent normal processing operation.

[0040] Furthermore, the movable frame 62 can move up and down above the sliding base 61, and the movement effect is controlled by the servo motor 81. Since the discharge pipe 86 is fixed on the output shaft of the servo motor 81, when the servo motor 81 drives the discharge pipe 86 to rotate, the discharge pipe 86 and the docking component 85 are engaged with each other, and the docking component 85 is arranged on one side of the rolling tooth 82. When the rolling tooth 82 is fixed, the discharge pipe 86 will drive the transmission mechanism 8 and the movable frame 62 to move up and down as a whole above the sliding base 61, and the movement effect is controlled by the rotation direction of the servo motor 81. At this time, the movable frame 62 descends to drive the resistance seat 71 to descend, so that the bottom surface of the processed blank 4 is separated from the top surface of the resistance seat 71, thereby preventing the movement of the processed blank 4 from causing wear between the resistance seat 71.

[0041] refer to Figure 6 and Figure 7 The docking assembly 85 includes a transmission gear 851 and a rotating disk 852. The two groups of servo motors 81 correspond to the two groups of transmission gears 851 respectively. The two groups of transmission gears 851 are respectively meshed on the left and right sides of the rotating disk 852. The rotating disk 852 rotates to drive the six groups of abutment seats 71 to move in the movable frame 62. A discharge pipe 86 is fixedly connected below the rotating disk 852. The aperture of the discharge pipe 86 is larger than the aperture of the blanking knife groove 72. The aperture of the blanking knife groove 72 is the same as the circular diameter of the punching knife below the punching knife seat 5. The discharge pipe 86 is located directly above the chip removal plate 3, and a through opening is provided at the position of the sliding base 61 close to the chip removal plate 3.

[0042] In the present embodiment, after the two groups of transmission teeth 851 rotate respectively under the drive of the two groups of servo motors 81, they can synchronously drive the rotating disk 852 to rotate. The rotating disk 852 can drive the six groups of abutment seats 71 to move in the movable frame 62 in the rotating state, thereby expanding the diameter of the blanking knife groove 72. At this time, the expansion of the diameter allows the edge material that was originally cut off inside the blanking knife groove 72 to fall normally into the discharge pipe 86, thereby realizing the normal discharge work into the chip removal plate 3 under the guidance of the discharge pipe 86.

[0043] refer to Figure 7Six groups of inclined slots 853 are provided on the surface of the rotating disk 852, and a connecting slide pin 854 is fixed below the abutment seat 71. The connecting slide pin 854 is slidably arranged in the inclined slot 853, and the abutment seat 71 is slidably connected to the movable frame 62 via a slide bar 855. A spring member 856 is sleeved on the surface of the slide bar 855, and the abutment seat 71 is elastically connected to the movable frame 62 via the spring member 856.

[0044] In the present embodiment, when the rotating disk 852 rotates, the six groups of inclined grooves 853 on its surface will also rotate synchronously. The bottom of the abutment seat 71 is subjected to force by the rotating pushing effect in the inclined groove 853 through the connecting slide pin 854, and one side of the abutment seat 71 is telescopically limited with the movable frame 62 through the slide rod 855. At the same time, a spring member 856 is sleeved on the surface of the slide rod 855. At this time, the movement of the abutment seat 71 will squeeze the spring member 856 to realize the unfolding operation. Otherwise, the abutment seat 71 will be reset under the elastic action of the spring member 856, thereby being reassembled into the blanking knife groove 72.

[0045] refer to Figure 3 , Figure 4 and Figure 6 A placement frame is provided on the movable frame 62 near the transmission gear 851 and the bevel gear group 84, an electromagnetic pull rod 857 is provided below the transmission gear 851, and the electromagnetic pull rod 857 is fixed to the placement frame, the bevel gear group 84 is composed of two groups of mutually meshing bevel gears, and the electromagnetic pull rod 857 drives the transmission gear 851 and the single bevel gear group 84 to move up and down through a movable bearing.

[0046] In the present embodiment, the arrangement of the mounting frame can provide a better active support effect for the transmission gear 851 and the bevel gear group 84, while the transmission gear 851 and the single bevel gear group 84 are connected to the output end of the electromagnetic pull rod 857 through a connecting shaft and a movable bearing. The electromagnetic pull rod 857 can drive the bevel gear groups 84 to separate from each other, so that the drive of the servo motor 81 can no longer continue to drive the transmission gear 851 to rotate at this time, so as to meet the requirements mentioned in the subsequent implementation plan: driving the sliding base 61 and the movable frame 62 to move longitudinally as a whole.

[0047] refer to Figure 3 and Figure 5 , clutch mechanisms 9 are arranged on both sides of the sliding base 61, and the clutch mechanisms 9 include a stand 91 and a swing rod 92, and the top of the swing rod 92 is rotatably connected to the stand 91 through a rotating pin. A movable groove 93 is arranged below the swing rod 92, and a pull pin 94 is slidably arranged in the movable groove 93, and an electromagnetic actuator is connected to one side of the pull pin 94, and the electromagnetic actuator is fixed to the bottom of the stand 91. A meshing groove 95 is arranged on one side of the swing rod 92 close to the bite tooth 96, and the stand 91 is fixedly connected to the sliding base 61, and the stands 91 corresponding to the two sets of clutch mechanisms 9 are arranged opposite to each other.

[0048] In this embodiment, under the support of the vertical frame 91, the rocker arm 92 will maintain a certain straightness, thereby providing a better meshing effect between the meshing groove 95 on one side and the meshing tooth 96, satisfying the effect of driving the movable frame 62 and the transmission mechanism 8 as a whole to move up and down through the meshing tooth 96 after being driven by the servo motor 81. When the pulling pin 94 is driven by the electromagnetic actuator to move to one side, the pulling pin 94 will pull the bottom of the rocker arm 92 through the movable groove 93. At this time, the rocker arm 92 will swing at a small angle with the movable position of the top vertical frame 91 as the center, thereby realizing the separation between the meshing groove 95 and the meshing tooth 96. At this time, the servo motor 81 drives the meshing tooth 96 to rotate and will no longer be able to continue to drive the movable frame 62 to move, so that it remains in an idling state.

[0049] refer to Figure 2 and Figure 6 A rolling tooth 82 is also fixedly connected to the output shaft of the servo motor 81 . The rolling tooth 82 is located on one side of the engaging tooth 96 . The rolling tooth 82 is butt-engaged with a base meshing plate 83 . The base meshing plate 83 is fixed on the surface of the machine platform 1 just below the rolling tooth 82 .

[0050] In this embodiment, combined with the above-mentioned embodiment, the meshing teeth 96 remain in an idling state. Because the meshing teeth 96 drive the movable frame 62 to fall before idling, the rolling teeth 82 and the base meshing plate 83 will be synchronously driven to engage with each other. If the servo motor 81 is continuously driven at this time, the sliding base 61 and the movable frame 62 will be driven to move horizontally as a whole on the surface of the machine 1 through the meshing effect of the rolling teeth 82 and the base meshing plate 83.

[0051] refer to Figure 2 The lateral driving component 2 includes a first slide rail 21 and a second slide rail 22. Two groups of sliders 23 are slidably arranged on the surfaces of the first slide rail 21 and the second slide rail 22 respectively. The single group of sliders 23 on the top of the first slide rail 21 is threadedly connected to the lead screw 25 through a transmission connecting plate. The lead screw 25 is fixedly rotated with the motor output shaft and arranged on one side of the machine 1. The single group of sliders 23 on the top of the first slide rail 21 and the second slide rail 22 are fixedly limited to each other by a stabilizing clamping plate 24.

[0052] In this embodiment, the surfaces of the first slide rail 21 and the second slide rail 22 are respectively slidably connected with two groups of sliders 23. After changing the relative distance between the two groups of sliders 23, the longitudinal position of the second slide rail 22 on the surface of the machine table 1 is changed at the same time, so that the processed blank 4 can be clamped and fixed by the block on the top of the slider 23, and the single group of sliders 23 on the top of the first slide rail 21 is threadedly connected with the lead screw 25. When the lead screw 25 is driven by the motor to rotate, it can drive the processed blank 4 to move horizontally as a whole, so as to realize the punching operation at different surface positions;

[0053] In order to improve the driving effect, the stabilizing clamping plate 24 can be connected to the sliders 23 at the top of the first slide rail 21 and the second slide rail 22 respectively, so that the lateral driving effect is smoother.

[0054] Working principle: First, adjust the relative positions of the first slide rail 21 and the second slide rail 22 in the transverse driving component 2, and fix the second slide rail 22, then slide the slider 23 on the top of the first slide rail 21 and the second slide rail 22, and set the processed blank 4 between the four groups of sliders 23 and fix it through the holder. At this time, the two groups of sliders 23 on the top of the first slide rail 21 and the second slide rail 22 are connected by the stabilizing clamping plate 24, and the lead screw 25 is driven by the motor. After the lead screw 25 rotates, it can drive the single group of sliders 23 on the top of the first slide rail 21 to move horizontally through the threaded connection effect, thereby driving the processed blank 4 as a whole to move horizontally on the top of the machine table 1, and cooperate with the longitudinal movement effect of the stamping tool holder 5 on the top of the machine table 1 to realize the need to punch holes at different positions on the surface of the processed blank 4;

[0055] When the punching tool holder 5 moves downward to punch the workpiece 4, the servo motors 81 on both sides of the movable frame 62 are driven. On the one hand, the servo motors 81 drive the meshing teeth 96 in the clutch mechanism 9 to rotate synchronously, and the meshing teeth 96 mesh with the meshing grooves 95 on one side of the swing rod 92, so that the meshing teeth 96 can crawl on one side of the swing rod 92 at this time, driving the movable base assembly 6 and the transmission mechanism 8 to move upward as a whole, until the six groups of abutment seats 71 on the inner side of the movable frame 62 are fitted with the bottom surface of the workpiece 4, meeting the fitting support, and preventing the workpiece 4 from being deformed during the punching process of the punching tool holder 5;

[0056] On the other hand, when the servo motor 81 drives the movable frame 62 to rise as a whole on the top of the sliding base 61, the bevel gear set 84 will also directly drive the transmission gear 851 to rotate. Since the transmission gear 851 is meshed with the rotating disk 852, the rotating disk 852 rotates under the abutment seat 71. The bottom of the abutment seat 71 slides through the inclined groove 853 provided on the surface of the rotating disk 852 and the connecting pin 854. When the rotating disk 852 rotates, the inclined groove 853 pushes the abutment seat 71 as a whole, so that the abutment seat 71 is moved upward through the sliding rod 855. The movable frame 62 moves in opposite directions. At this time, the six groups of abutment seats 71 are butted against each other, and a blanking knife groove 72 with the same aperture as the punching knife below the punching knife seat 5 is formed at the center of the circle, so as to meet the operation of docking and punching, improve the neatness of the hole edge after punching, and reduce the deformation of the processed blank 4. On the contrary, when the servo motor 81 drives the movable frame 62 to descend as a whole, the six groups of abutment seats 71 move away from each other and squeeze the spring member 856 to expand, and the blanking knife groove 72 is expanded. The waste material inside the blanking knife groove 72 will fall into the chip discharge plate 3 through the discharge pipe 86 to be collected;

[0057] Finally, when the punching tool holder 5 moves longitudinally, the servo motor 81 will continue to drive the movable frame 62 to descend until the rolling tooth 82 is docked and meshed with the base meshing plate 83 on the top of the machine table 1. At this time, the vertical frame 91 in the clutch mechanism 9 on both sides of the sliding base 61 will provide a support effect for the rocker arm 92. When the pull pin 94 is driven by the electromagnetic actuator to move on one side of the vertical frame 91, the rocker arm 92 will be pulled through the movable groove 93 to swing at a small angle as a whole, so that the meshing groove 95 is disengaged from the meshing tooth 96. Similarly, the electromagnetic pull rod 857 under the transmission tooth 851 will also lift the bevel gear group 84 to separate from each other. At this time, the driving effect of the servo motor 81 will only drive the rolling tooth 82 to rotate on the base meshing plate 83, thereby driving the sliding base 61 and the movable frame 62 to move longitudinally as a whole until they are aligned with the punching tool holder 5 above the processed blank 4.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
