Description

Technical Field

[0001] The present application relates to the technical field of CNC punching machines, and in particular to a CNC punching machine for plate processing. Background Art

[0002] CNC punching machine is the abbreviation of digital control punching machine. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions and decode them to make the punching machine move and process parts.

[0003] Through searching, Chinese patent announcement number CN218425043U discloses a CNC punching machine capable of preventing deformation of plates. The plates can be placed by setting a processing support plate, and the interval between the two first clamping plates can be adjusted by setting an adjustment component to ensure that it can adapt to plates of different specifications, and the plates can be fixed and clamped laterally by the first clamping plate. The threaded rod can be driven to rotate by setting a driving motor. The rotation of the threaded rod will drive the threaded seat to move in the opposite direction in the movable groove through the opposite threads. The threaded seat will drive the first clamping plate to move while moving, so that the plates are fixed and clamped laterally by the first clamping plate. The plates can be fixed and clamped longitudinally by setting a clamping component. After the plates are fixed and clamped laterally, the adjusting dial is rotated, and the adjusting dial drives the adjusting bolt and the second clamping plate thereon to move downward, so that the plates are fixed and clamped longitudinally. Since two-way fixation can be provided, the fixing effect is ideal. It is not easy to deviate or fall during processing, and it is not easy to cause uneven force and cause deformation of the plates.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: when the above-mentioned scheme and the existing CNC punch press clamp the plate, the plate is placed on the base of the CNC punch press, and the side of the plate is clamped by the clamping plate. However, during production, the side of the plate may be uneven, so that the concave surface of the plate is not easy to be clamped by force when clamped, and it is easy to cause misalignment during plate processing. Utility Model Content

[0005] In order to clamp the concave part of the uneven surface of the plate, the present application provides a CNC punching machine for plate processing.

[0007] Optionally, the side of the slider away from the axis of the punch base is a groove-shaped structure, a reset spring is fixedly connected inside the groove-shaped structure of the slider, the other end of the reset spring is fixedly connected to the inner wall of the support, and the round rod is located on the inner annular surface of the corresponding reset spring.

[0008] Optionally, one end of the two engaging push plates that is close to each other is fixedly connected to a positioning spring, and the other end of the positioning spring is fixedly connected to the inner bottom wall of the adjacent connecting plate.

[0009] Optionally, a side of the corner block close to the support platform is an inclined surface, and the lower end of the corner block is a pointed end.

[0010] Optionally, both left and right ends of the bottom surface of the arc bottom plate are arc-shaped, and a corner of the upper end of the inclined push plate close to the arc bottom plate is an inclined surface.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The utility model is provided with components such as vertical rods, sliding blocks, round rods, corner blocks, and lower clamping plates. The meshing push plate first drives the support platform and the vertical clamping rod to approach the plate through the insert block. When the vertical clamping rod contacts the side of the plate, the plate gradually pushes the vertical clamping rod to slide in the support platform, and the round rod is gradually pushed out of the support platform. The round rod contacts the inclined surface of the corner block, and the corresponding insert block is pulled out of the long groove through the vertical rod. When the most concave part of the plate contacts the vertical clamping rod, the remaining parts have already contacted the vertical clamping rod. After the vertical rod located at the concave part pushes the round rod connected thereto to completely move below the corner block, all the insert blocks are completely disengaged from the long groove, and the meshing push plate moves into the connecting plate, and the inclined push plate pushes the lower clamping plate upward to contact the round rod, fixes the positions of the round rod and the vertical rod relative to the support platform, so that when the two meshing push plates are close to each other, the vertical clamping rods on both sides can contact and clamp the concave and convex surfaces of the plate.

[0015] 2. The utility model sets a positioning spring and a return spring. When the engaging push plate is not subjected to a thrust, the positioning spring makes the distance between the connecting plate and the engaging push plate just make the insert block located at the long slot. The elasticity of the return spring is greater than that of the positioning spring. When the vertical clamp rod drives the return spring to be compressed and the insert block is separated from the long slot, the engaging push plate is subjected to a thrust and approaches the connecting plate to compress the positioning spring, so that the inclined push plate moves to the arc bottom plate to push the lower clamp plate to clamp the round rod.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-5 This application is described in further detail.

[0023] The present application embodiment discloses a CNC punch press for plate processing. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes a punch press base 1, a power bidirectional threaded rod 2 is installed inside the punch press base 1, two engaging push plates 3 are slidably inserted on the upper surface of the punch press base 1, and the engaging push plates 3 are threadedly sleeved on the outer surface of the power bidirectional threaded rod 2. When the two engaging push plates 3 are respectively engaged with the power bidirectional threaded rod 2 rotating forward and reversely, they approach and move away from each other respectively, and a connecting plate 6 is slidably sleeved on one end of the engaging push plates 3 close to the axis of the punch press base 1, and a support 4 is fixedly connected to the upper surface of the connecting plate 6, and a plurality of sliders 7 are slidably inserted on the upper surface of the support 4, and a side of the slider 7 away from the axis of the punch press base 1 is fixedly connected with The round rod 5, the other end of the round rod 5 slides through the inner wall of the support platform 4, the upper surface of the slider 7 is fixedly installed with a vertical clamping rod 19, the side of the slider 7 away from the axis of the punch base 1 is a groove-shaped structure, and a reset spring 17 is fixedly connected inside the groove-shaped structure of the slider 7, and the other end of the reset spring 17 is fixedly connected to the inner wall of the support platform 4. The round rod 5 is located on the inner annular surface of the corresponding reset spring 17, and the reset spring 17 makes the vertical clamping rod 19 push the round rod 5 to be completely located inside the support platform 4 before contacting the plate, thereby limiting the initial position of the vertical clamping rod 19, and the groove-shaped structure of the slider 7 can store the compressed reset spring 17.

[0024] See also Figure 2 A corner block 9 is arranged on the side of the support platform 4 away from the axis of the punch base 1 and above the round rod 5, and an insert block 8 is arranged below the corner block 9. The bottom surface of the corner block 9 and the two sides of the adjacent round rod 5 are fixedly connected with vertical rods 10. The support platform 4 is slidably sleeved on the outer surface of the corresponding vertical rod 10, and the other end of the vertical rod 10 is fixedly connected to the insert block 8 located directly below it. The outer surface of each vertical rod 10 is sleeved with a push spring 11, and the two ends of the push spring 11 are respectively fixedly connected to the support platform 4 and the insert block 8, and the upper surface of the engaging push plate 3 is provided with a long Slot 12, the plug block 8 is slidably inserted into the inside of the long slot 12 directly below it, the side of the corner block 9 close to the support platform 4 is an inclined surface, and the lower end of the corner block 9 is a pointed end. When the round rod 5 extends from the support platform 4, the round rod 5 pushes the corner block 9 to move upward by contacting with the inclined surface of the corner block 9. When the corner block 9 is completely moved to the top of the round rod 5, the plug block 8 is completely disengaged from the long slot 12. After all the vertical clamping rods 19 are in contact with the side of the plate and subjected to force, when all the plug blocks 8 are pushed to be misaligned with the long slot 12, the meshing push plate 3 can move relative to the connecting plate 6.

[0025] See also Figure 2The ends of the engaging push plates 3 that are close to each other are fixedly connected with a positioning spring 18, and the other end of the positioning spring 18 is fixedly connected to the inner bottom wall of the adjacent connecting plate 6. When the engaging push plates 3 are not subjected to external force, the positioning spring 18 makes the long groove 12 located below the plug block 8. The elasticity of the positioning spring 18 is smaller than that of the return spring 17. After the plug block 8 is disengaged from the long groove 12, the engaging push plates 3 will approach the connecting plate 6 by compressing the positioning spring 18.

[0026] See also Figure 3 A curved bottom plate 13 is arranged above the meshing push plate 3, and the curved bottom plate 13 is elastically connected to the meshing push plate 3 located directly below by two spring telescopic rods 15. A lower clamping plate 14 is arranged below the side of the round rod 5 away from the axis of the punch base 1, and the bottom surface of the other end of the lower clamping plate 14 is fixedly connected to the upper surface of the adjacent curved bottom plate 13. The two curved bottom plates 13 are arranged on the side away from each other with an inclined push plate 16, and the bottom surface of the inclined push plate 16 is fixedly connected to the upper surface of the adjacent meshing push plate 3. The left and right ends of the bottom surface of the curved bottom plate 13 are both arc-shaped, and the upper end of the inclined push plate 16 is close to the corner of the curved bottom plate 13 as an inclined surface. When the inclined push plate 16 is completely moved to the bottom of the curved bottom plate 13, the lower clamping plate 14 is pushed to clamp the round rod 5, and the position of the vertical clamping rod 19 relative to the support platform 4 is fixed. At this time, the connecting plate contacts the side end surface of the meshing push plate.

[0027] See also Figure 4 The upper surface of the lower clamping plate 14 is a circular arc concave structure, and the inner diameter of the circular arc concave structure of the lower clamping plate 14 is equal to the outer diameter of the round rod 5, so that the upper surface of the lower clamping plate 14 can fully contact with the round rod 5 to fix it.

[0028] See also Figure 5 The inner wall width of the long groove 12 is equal to the width of the plug block 8 , and both left and right ends of the bottom surface of the plug block 8 are rounded to facilitate inserting the plug block 8 into the long groove 12 .

[0029] The implementation principle of a CNC punching machine for plate processing in the embodiment of the present application is as follows: two meshing push plates 3 mesh with the power bidirectional threaded rod 2 and approach each other, the meshing push plates 3 first drive the support table 4 and the vertical clamping rod 19 to approach the plate through the insert block 8, when the vertical clamping rod 19 contacts the side of the plate, the plate gradually pushes the vertical clamping rod 19 to slide in the support table 4, compressing the reset spring 17, and gradually pushing the round rod 5 out of the support table 4, the round rod 5 contacts the inclined surface of the corner block 9 to push the corner block 9 to move upward, and the corresponding insert block 8 is pulled out of the long groove 12 through the vertical rod 10, and when the most concave part of the plate contacts the vertical clamping rod 19, the rest of the parts have been connected with the vertical clamping rod 19. After the vertical rod 10 located in the recess pushes the round rod 5 connected thereto to move completely below the corner block 9, and all the plug blocks 8 are disengaged from the long grooves 12, the engaging push plate 3 moves into the connecting plate 6 to compress the positioning spring 18, and the inclined push plate 16 contacts the arc surface of the arc bottom plate 13 and slides to push the lower clamping plate 14 to move upward. When the inclined push plate 16 is completely moved below the arc bottom plate 13, the lower clamping plate 14 contacts and presses the round rod 5 tightly. At this time, the engaging push plate 3 contacts the inner wall of the connecting plate 6, fixing the positions of the round rod 5 and the vertical rod 10 relative to the support platform 4, so that when the two engaging push plates 3 are close to each other, the vertical clamping rods 19 on both sides can contact and clamp the concave and convex surfaces of the plate.
