Description
Technical Field
[0001] The invention relates to the technical field of metal plate stamping, in particular to a punching device for punching a workpiece based on transmission-type rapid movement. Background Art
[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.
[0003] Punching is also a process in stamping. Punching refers to punching various patterns on steel plates, leather, cloth, wood boards and other materials to meet different needs, including eight-shaped holes, hexagonal holes, perforated plates, long holes, square holes, round holes, perforated plate nets, triangular holes, etc.
[0004] The Chinese patent with the publication number CN112676442A discloses a punching machine, which includes a workbench, a base, the base is movably mounted on the workbench, and the base is used to carry a sheet; a detection device, the detection device is mounted on the workbench and is above the sheet, and the detection device is used to detect the position information of the sheet set on the surface of the base; a punch, the punch is mounted on the surface of the workbench, and the punch is used to punch the sheet on the base by moving up and down; a control module, the control module is connected to the detection device; the control module is connected to the base to control the movement of the base to adjust the position of the sheet; the control module is connected to the punch to control the up and down movement of the punch to punch the sheet. Since the position of the sheet is detected and adjusted accordingly before punching, the punching accuracy of the punching machine is improved.
[0005] The above patent controls the base through the control module so that the base drives the workpiece to move during the stamping process. Although this can improve the processing accuracy of punching, when the product needs to be proofed during the research and development process, it is necessary to adjust the hole spacing of the punched holes on the surface of the workpiece, and the adjustment method is to change the single movement distance of the base during the punching process. In this way, if the movement distance of the base is adjusted by electronic means (cooperation of the control module and the motor), it is necessary to frequently change the drive parameters in the control module, and the modification of the drive parameters is usually performed by programmers, so programmers and R&D personnel are required to cooperate with each other, which is not conducive to improving the efficiency of proofing during the research and development process. Summary of the invention
[0006] The object of the present invention is to provide a punching device for punching a workpiece based on transmission-type rapid movement, so as to solve the problems raised in the above-mentioned background technology.
[0007] In order to achieve the above-mentioned purpose, a punching device for punching workpieces based on transmission-type rapid movement is provided, including a base and a support base fixed above the top of the base, a hydraulic rod is fixedly installed on the top of the support base, the movable end of the hydraulic rod is set downward and fixedly connected to a pressure plate, a plurality of punches are fixedly set on the bottom of the pressure plate, and a punching base for placing the workpiece is also fixedly set on the top of the base, and a punching groove is opened on the top of the punching base for the punch to penetrate during the downward movement.
[0008] Driving mechanisms for driving the workpiece to move on the top of the stamping base are arranged on both sides of the stamping base, and the driving mechanisms are connected to the pressure plate. A hole distance sensing mechanism is arranged above the stamping base on the path where the workpiece moves during the punching process, and the hole distance sensing mechanism is movably arranged on the top of the stamping base so that the distance between the hole distance sensing mechanism and the stamping groove is adjustable, which is used to adjust the hole distance of the punching; the hole distance sensing mechanism is connected to the driving mechanism.
[0009] During the downward movement of the pressure plate, the driving mechanism converts the power of the downward movement of the pressure plate into power to drive the workpiece to move, so that the driving mechanism drives the workpiece to move during the downward movement of the pressure plate. When the hole on the surface of the workpiece moves below the hole distance sensing mechanism, the hole distance sensing mechanism interrupts the connection between the driving mechanism and the pressure plate, and extends into the hole on the surface of the workpiece to fix the workpiece.
[0010] As a further improvement of the present technical solution, the driving mechanism includes side plates opposite to each other on both sides of the stamping base, and adjacent sides of the two side plates are rotatably provided with multiple rollers, and a driving chamber for the workpiece to pass through is formed between the multiple rollers, and the rollers are rotated by the downward movement of the pressure plate.
[0011] As a further improvement of the present technical solution, a gear plate is provided on the side of the side plate opposite to the roller, and the gear plate is coaxially fixedly connected to one of the rollers, so that the gear plate and the roller maintain a synchronous rotation state, and the outer ring of the gear plate is meshed with a rack slidably set at the bottom of the pressure plate, and a reset spring is fixedly set on one side of the rack, and one end of the reset spring is fixedly set at the bottom of the pressure plate for resetting by pushing the rack.
[0012] As a further improvement of the technical solution, the hole distance sensing mechanism includes a base plate slidably arranged on both sides of the side plate, and a movable plate elastically arranged on the top of the base plate by connecting springs, a sliding rod is fixedly arranged at the bottom of the movable plate, the bottom end of the sliding rod slides through the base plate, and when the hole on the workpiece is located below the sliding rod, the bottom end of the sliding rod is elastically moved downward by the connecting spring and extends into the hole to form a probe; The top of the side plate is fixedly connected to a limiting tube, a driven plate is slidably arranged in the limiting tube, and one end of the driven plate close to the movable plate is in an arc state and bent downward; The two ends of the movable plate extend above the driven plate to form a driving end that pushes the driven plate toward the rack through the arc surface of the driven plate during the downward movement of the movable plate; A connecting rope connecting the movable plate and the pressure plate is provided between the two. The length of the connecting rope is greater than the distance that the rack separates from the gear plate when it moves upward, so that after the bottom end of the rack is higher than the gear plate, the pressure plate moves upward and resets by pulling the connecting rope through the connecting rope.
[0013] As a further improvement of the technical solution, two clamping plates are fixedly provided on the side wall of the side plate, a slideway structure for the base plate to slide is formed between the two clamping plates, and a bolt for locking the base plate is provided on the top thread of the clamping plate.
[0014] As a further improvement of the technical solution, the width of the driven plate is consistent with the sliding distance of the base plate.

Abutment plates are fixedly arranged on both sides of the bottom of the substrate, and the bottom ends of the abutment plates are attached to the upper surface of the workpiece.
[0016] When the elastic pusher pushes the bottom of the hole on the workpiece, the abutment plate limits the upward movement of the workpiece so that the push force of the elastic pusher acts entirely on the bottom of the hole on the workpiece to correct the bent workpiece.
[0017] As a further improvement of the technical solution, the elastic pusher includes an elastic plate and a limit block fixedly arranged on the top of the probe, and the elastic plate and the limit block are arranged in a plurality in a circular array, thereby forming a circular state on the top of the probe; the top of the elastic plate is inclined toward the outer ring of the probe and then bent upward to form an "L"-shaped structure, and the bending part of the elastic plate protrudes from the outer ring of the probe; The limit block is located outside the elastic plate and is used to improve the elasticity of the elastic plate when it is subjected to an outward force.
[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. In the punching device for punching workpieces based on transmission-type rapid movement, the distance between the hole spacing sensing mechanism and the punching groove represents the hole spacing of the punching holes. After the hole spacing adjustment is completed, the moving distance of the workpiece is controlled by sensing the punched positions on the workpiece, so that when punching the same workpiece, the adjacent hole spacings are consistent, thereby improving the efficiency of adjusting the adjacent hole spacings to reduce the participation of staff.
[0019] 2. In the punching device for workpiece punching based on transmission-type rapid movement, the probe can not only sense the position of the hole, but also push the bottom of the hole on the workpiece during the up and down movement of the probe, thereby offsetting the downward punching force on the upper surface of the workpiece, achieving correction of the workpiece, and avoiding bending and warping of the workpiece after dense punching.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0023] See also Figure 1 As shown, a punching device for punching workpieces based on transmission-type rapid movement is provided, including a base 100, and a support base 101 fixed above the top of the base 100 by four cylinders, a hydraulic rod 102 is fixedly installed on the top of the support base 101, and the movable end of the hydraulic rod 102 is set downward and fixedly connected to a pressing plate 103, so that the movable end of the hydraulic rod 102 can drive the pressing plate 103 to move downward, and a plurality of punches 104 are fixedly arranged at the bottom of the pressing plate 103 for following the downward movement of the pressing plate 103 to punch the workpiece 105. In addition, the pressing plate 103 can be longitudinally slidably connected to the four cylinders to improve the stability of the pressing plate 103 during the downward movement of the punching process. And, refer to Figure 2 As shown, a stamping base 110 for placing a workpiece 105 is fixedly provided on the top of the base 100, and a stamping groove 111 is opened on the top of the stamping base 110 for the punch 104 to penetrate during the downward movement. Before the punch 104 penetrates the stamping groove 111, the punch 104 punches the hole of the workpiece 105 by moving downward and squeezing.
[0024] Next, see Figure 3 As shown, driving mechanisms 120 for driving the workpiece 105 to move on the top of the stamping base 110 are arranged on both sides of the stamping base 110, and the driving mechanism 120 is connected to the pressing plate 103. A hole distance sensing mechanism 130 is arranged above the stamping base 110 and on the path where the workpiece 105 moves during the punching process. The hole distance sensing mechanism 130 is movably arranged on the top of the stamping base 110 so that the distance between the hole distance sensing mechanism 130 and the stamping groove 111 is adjustable, which is used to adjust the hole distance of the punching; in addition, the hole distance sensing mechanism 130 is connected to the driving mechanism 120.
[0025] During the downward movement of the pressure plate 103, the driving mechanism 120 converts the power of the downward movement of the pressure plate 103 into the power to drive the workpiece 105 to move, so that the driving mechanism 120 drives the workpiece 105 to move during the downward movement of the pressure plate 103. When the hole on the surface of the workpiece 105 moves below the hole distance sensing mechanism 130, the hole distance sensing mechanism 130 interrupts the connection between the driving mechanism 120 and the pressure plate 103, and extends into the hole on the surface of the workpiece 105 to fix the workpiece 105.
[0026] That is to say, the distance between the hole spacing sensing mechanism 130 and the punching groove 111 represents the hole spacing of the punching. After the hole spacing adjustment is completed, the moving distance of the workpiece 105 is controlled by sensing the punched position on the workpiece 105, so that when punching the same workpiece 105, the adjacent hole spacing is consistent, thereby improving the efficiency of adjusting the adjacent hole spacing to reduce the participation of staff.
[0027] Example 1 like Figure 4 As shown, the driving mechanism 120 includes side plates 121 disposed on both sides of the stamping base 110, and at least two rollers 122 are rotatably arranged on the adjacent sides of the two side plates 121, wherein one roller 122 is located at the top and the other roller 122 is located at the bottom, and a driving chamber for the workpiece 105 to pass through is formed between the two rollers 122. When one of the rollers 122 rotates, under the action of friction, the two rollers 122 rotate relative to each other to move the workpiece 105 in the driving chamber. And the top of the roller 122 located at the bottom is kept flush with the height of the stamping base 110, so that when the workpiece 105 is in the driving chamber, the bottom surface is in contact with the top surface of the stamping base 110.
[0028] Next, the rotation of the roller 122 is driven by the downward movement of the pressure plate 103. The specific structure is as follows: a gear plate 123 is provided on one side of the side plate 121 relative to the roller 122, and the gear plate 123 is coaxially fixedly connected with one of the rollers 122, so that the gear plate 123 and the roller 122 maintain a synchronous rotation state. Then, the outer ring of the gear plate 123 is meshed with a rack 124 located at the bottom of the pressure plate 103. In this way, the pressure plate 103 will drive the rack 124 to move downward during the downward movement. Through the meshing of the gear plate 123 and the rack 124, the downward movement of the rack 124 is converted into a rotational movement by the gear plate 123, and the rotating gear plate 123 will transmit the rotational power to the roller 122, so that the roller 122 is in a rotating state. Secondly, the rack 124 is slidably set at the bottom of the pressure plate 103, and is used to cooperate with the hole distance sensing mechanism 130 to achieve power interruption control by sliding away from the gear plate 123 (the specific cooperation method will be described in detail below). A reset spring 125 is fixedly set on one side of the rack 124, and one end of the reset spring 125 is fixedly set at the bottom of the pressure plate 103, and is used to reset by pushing the rack 124.
[0029] like Figure 5As shown, the hole distance sensing mechanism 130 includes a base plate 131 slidably arranged on both sides of the side plate 121, and a movable plate 134 elastically arranged on the top of the base plate 131 through a connecting spring 135. A sliding rod 132 is fixedly arranged at the bottom of the movable plate 134. The bottom end of the sliding rod 132 slides through the base plate 131. When the hole on the workpiece 105 is located below the sliding rod 132, the bottom end of the sliding rod 132 elastically moves downward through the connecting spring 135 and extends into the hole to form a probe 133, thereby sensing the hole position on the workpiece 105. In addition, combined with Figure 4 As shown, the top of the side plate 121 is fixedly connected to a limit tube 127, and a driven plate 128 is slidably arranged in the limit tube 127. The end of the driven plate 128 close to the movable plate 134 is in an arc state and bent downward. In addition, the two ends of the movable plate 134 extend to the top of the driven plate 128, so as to form a driving end that pushes the driven plate 128 toward the rack 124 through the arc surface of the driven plate 128 during the downward movement of the movable plate 134. In addition, a connecting rope 136 is arranged between the movable plate 134 and the pressing plate 103 to connect the two. The length of the connecting rope 136 is greater than the distance that the rack 124 is separated from the gear plate 123 when it moves upward, so that after the bottom end of the rack 124 is higher than the gear plate 123, the pressing plate 103 pulls the connecting rope 136 to move up and reset through the connecting rope 136.
[0030] The specific sliding connection between the side plate 121 and the base plate 131 is that two clamping plates 126 are fixedly arranged on the side wall of the side plate 121, a slideway structure is formed between the two clamping plates 126, and the end of the base plate 131 is located in the slideway structure for the base plate 131 to slide. In addition, after sliding to a specified position, the base plate 131 can be locked by means of a thread to prevent the base plate 131 from sliding further. Specifically, a bolt can be arranged on the top of the clamping plate 126, and the bolt can be screwed into the slideway to squeeze the base plate 131, so that the base plate 131 is locked.
[0031] It should be noted that the reference Figure 4 The width of the driven plate 128 is consistent with the sliding distance of the base plate 131, so that the driving end of the movable plate 134 can be prevented from being separated from the driven plate 128 due to sliding far.
[0032] Working principle: Combination Figure 6 As shown, firstly, the position of the base plate 131 is adjusted by sliding, and the base plate 131 drives the sliding rod 132 to move, and the plane distance between the sliding rod 132 and the punch 104 after the movement is the spacing between the two rows of holes. Then, the workpiece 105 is punched for the first time, and during the first punching, the workpiece 105 does not contact the roller 122, and then after the first punching is completed, the punch 104 is manually pushed into the driving chamber between the two rollers 122.
[0033] Then, during the downward movement of the pressure plate 103, the punch 104 and the rack 124 will be driven downward at the same time. The downward movement of the rack 124 will drive the roller 122 to rotate through the gear plate 123, and the rotation of the roller 122 will drive the workpiece 105 to move. When the hole on the workpiece 105 moves to the bottom of the sliding rod 132, the probe 133 elastically moves downward through the connecting spring 135 and extends into the hole. At this time, the connecting spring 135 will also pull the movable plate 134 downward. During the downward movement, the driving end of the movable plate 134 will push the driven plate 128 toward the rack 124 through the arc surface of the driven plate 128, so that the driven plate 128 pushes the rack 124 to disengage from the gear plate 123. At this time, the downward movement of the rack 124 will not drive the gear plate 123 to rotate, and the workpiece 105 that has lost power will stop moving. At this time, the probe 133 extends into the hole of the workpiece 105 and also limits the workpiece 105.
[0034] Then, as the pressing plate 103 continues to move downward, the punch 104 at the bottom of the pressing plate 103 punches the workpiece 105 for the second time. After the second punching is completed, the pressing plate 103 drives the punch 104 and the rack 124 to move upward and reset. At this time, the base plate 131 is not in a straight state, and the pressing plate 103 will not pull the movable plate 134 upward and reset through the base plate 131. The movable plate 134 fails to reset, and accordingly, the rack 124 will also be separated from the gear plate 123, thereby preventing the rack 124 from driving the gear plate 123 to reverse. When the bottom end of the rack 124 is higher than the outer ring of the gear plate 123, the distance between the pressure plate 103 and the movable plate 134 is greater than the length of the connecting rope 136, so that the connecting rope 136 is in a straightened state, thereby pulling the movable plate 134 upward to reset. At this time, the movable plate 134 drives the sliding rod 132 to disengage from the hole on the workpiece 105, and at the same time, the driving end of the movable plate 134 also disengages from the driven plate 128 and no longer pushes the driven plate 128. At this time, the reset spring 125 pushes the rack 124 to reset through its own elasticity. When the pressure plate 103 moves down again, the rack 124 moves down and meshes with the gear plate 123.
[0035] Example 2 Considering that when the workpiece 105 is densely punched, the upper surface of the workpiece 105 will be subjected to a downward punching force, which may cause the workpiece 105 to bend and warp. Figure 7-Figure 9As shown, a groove 112 for the probe 133 to penetrate is provided at the top of the stamping base 110, and an elastic pusher 140 is provided at the top of the probe 133. The elastic pusher 140 is used to push the bottom of the hole on the workpiece 105 when the probe 133 moves up and away from the workpiece 105. At the same time, the elastic pusher 140 is matched with a stop plate 150, which is fixedly arranged on both sides of the bottom of the base plate 131, and the bottom end of the stop plate 150 is attached to the upper surface of the workpiece 105. In this way, when the elastic pusher 140 pushes the bottom of the hole on the workpiece 105, the stop plate 150 will limit the upward movement of the workpiece 105, so that the push force of the elastic pusher 140 is fully applied to the bottom of the hole on the workpiece 105, so as to correct the bent workpiece 105.
[0036] Specifically, the elastic pusher 140 includes an elastic plate 141 and a stopper 142 fixedly arranged on the top of the probe 133. A plurality of the elastic plates 141 and the stopper 142 are arranged in a circular array, thereby forming a circular state on the top of the probe 133 to push the hole in all directions. The top of the elastic plate 141 is tilted toward the outer ring of the probe 133 and then bent upward to form an "L"-shaped structure, and the bending part of the elastic plate 141 protrudes from the outer ring of the probe 133. The stopper 142 is located on the outside of the elastic plate 141, and is used to improve the elasticity of the elastic plate 141 when it is subjected to an outward force.
[0037] Working principle: Combination Fig. 9 As shown, when the probe 133 moves downward and penetrates the hole on the workpiece 105, the hole will apply a thrust force to the elastic pusher 140 toward the sliding rod 132 (such as Fig. 9 When the probe 133 is moved upward to reset, since the bent portion of the elastic plate 141 protrudes from the outer ring of the probe 133, and the outer diameter of the probe 133 is consistent with the inner diameter of the hole, the probe 133 drives the elastic plate 141 to move upward, and a thrust force is applied to the bent end of the elastic plate 141 toward the outer periphery of the probe 133 (such as Fig. 9 141 is deformed outwards by force, but during the deformation process, the elastic plate 141 is pushed by the stop block 142, so that the anti-thrust performance of the elastic plate 141 is increased, so that the bent end of the elastic plate 141 applies a pushing force to the hole, and then cooperates with the limit of the stop plate 150 to offset the downward punching force on the upper surface of the workpiece 105, so as to achieve the correction of the workpiece 105. When the force between the hole and the elastic plate 141 is greater than the anti-thrust force added to the elastic plate 141 by the stop block 142, the elastic plate 141 is deformed to allow the probe 133 to move upward through the hole.
[0038] That is to say, the probe 133 can not only sense the position of the hole, but also push the bottom of the hole on the workpiece 105 during the up and down movement of the probe 133, thereby offsetting the downward punching force on the upper surface of the workpiece 105, achieving correction of the workpiece 105, and avoiding the workpiece 105 from bending and warping after dense punching.
