Description

Technical Field

[0001] The present invention relates to the technical field of steel plate punching, and particularly relates to a punching machine for stainless steel plates with automatic center positioning. Background Art

[0002] Due to its corrosion resistance characteristics, stainless steel plates are widely used in various industrial and construction fields, having good corrosion resistance and mechanical properties, and are the most common type; during the processing of stainless steel plates, a punching machine is generally used to punch holes in the steel plates. During the existing steel plate processing, the lifting vertical plate drives the punching electric drill to move downward, and the punching electric drill is moved to the position where the hole needs to be punched in the center of the steel plate to achieve the positioning punching of the steel plate; and after the steel plate punching is completed, the steel plate is conveyed to the support plate by the movement of the material conveying component, and then manually carried. Since the steel plate is attached to the support plate, the operator's hand can only be buckled at both ends of the steel plate to lift it. Because iron powder is easily generated on the surface of the steel plate during processing, the operator is prone to slide between the steel plate and the hand when lifting the steel plate, resulting in the steel plate detaching from the operator's hand and falling, causing the steel plate to be bumped and damaged, and reducing the processing effect of the punching equipment on the steel plate.

[0035] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The present invention provides a punching machine for stainless steel plates with automatic center positioning as shown in Figures 1-5 Figure 18, which includes: a frame 1 and a steel plate main body 12. Support plates 13 are installed at both ends of the frame 1, and a plurality of rollers 14 are installed on both support plates 13. A punching head 11 is installed at the top of the frame 1;

[0037] A support component 2 for lifting the steel plate main body 12 above the support plate 13 and the rollers 14. The support component 2 includes a support frame 21 fixed on one side of the frame 1 for the support plate 13 to support, and two stabilizing plates 22 symmetrically installed at the top of the support plate 13. Two connecting frames 25 that cooperate with the two stabilizing plates 22 are slidably connected to both ends of the support plate 13, and disassembly and assembly components 6 for quickly installing or disassembling the two stabilizing plates 22 are provided on both connecting frames 25. Connecting rods 23 are fixed to the bottom ends of the two connecting frames 25. Two connecting grooves 24 for the two connecting rods 23 to slide are opened on the support frame 21. Two groups of control components 3 for driving the two connecting rods 23 to move are provided on the support frame 21. Two groups of limiting components 4 for limiting the steel plate main body 12 are provided on both connecting frames 25.

[0038] Each group of control components 3 includes a control rod 34 fixed on one side of the connecting rod 23, a control groove 33 opened on one side of the support frame 21, and a threaded column 32 rotatably installed in the control groove 33. A moving ring 31 is sleeved outside the threaded column 32. A through groove communicating with the inside of the connecting groove 24 is opened on one side of the control groove 33. One end of the control rod 34 extends into the through groove and is fixed outside the moving ring 31. A servo motor 35 is installed at the top of the support frame 21, and the servo motor 35 is used to drive the threaded column 32 to rotate.

[0039] When it is necessary to carry the steel plate body 12 on the support plate 13, first, the steel plate body 12 is drilled by the drilling head 11 in the frame 1, and the processed steel plate body 12 is moved out towards the support plate 13 by the feeding component in the frame 1. Then, the roller 14 is used to guide the movement of the steel plate body 12 on the support plate 13, and the steel plate body 12 is placed on the support plate 13. And two stabilizing plates 22 are located in the middle of the bottom of the steel plate body 12. Driven by the servo motor 35, the threaded column 32 rotates in the control groove 33, and the threaded column 32 and the moving ring 31 are in screw transmission, moving the moving ring 31 up or down along the outside of the threaded column 32. However, when the moving ring 31 moves upward, it drives the control rod 34 to slide upward along the through groove. As the control rod 34 moves, it drives the connecting rod 23 to slide upward in the connecting groove 24, and then the connecting frame 25 slides upward along one side of the support plate 13. Subsequently, the movement of the connecting frame 25 drives the two stabilizing plates 22 to move upward, so that the stabilizing plates 22 lift the steel plate body 12, keeping a distance between the steel plate body 12 and the support plate 13 that allows the operator's hand to be inserted, facilitating the operator to stably lift the steel plate body 12.

[0040] Furthermore, a cleaning component 5 is also provided on one side of the stabilizing plate 22, and the cleaning component 5 is used to clean the bottom of the steel plate body 12 when it passes by the stabilizing plate 22;

[0041] The cleaning component 5 includes a cleaning brush 51 installed on one side of the stabilizing plate 22 and in contact with the bottom of the steel plate body 12, and a first screw hole 52 opened at the bottom of the cleaning brush 51. A second screw hole 54 is opened on one side of the stabilizing plate 22, and a bolt 53 is screwed on the stabilizing plate 22, and the bolt 53 is screwed into the first screw hole 52 corresponding to the second screw hole 54 through the second screw hole 54. Based on this, before the stabilizing plate 22 moves, first, the cleaning brush 51 is attached to the stabilizing plate 22, and the angle of the cleaning brush 51 is pre-adjusted so that the top of the cleaning brush 51 is level with the top of the stabilizing plate 22. Then, the first screw hole 52 and the second screw hole 54 are aligned. At this time, the bolt 53 is screwed into the second screw hole 54 and the first screw hole 52 to stably install the cleaning brush 51 on one side of the stabilizing plate 22. However, the roller 14 guides the movement of the steel plate body 12. As the steel plate body 12 moves and slides over the stabilizing plate 22 and the cleaning brush 51, the protruding part at the top of the cleaning brush 51 is used to clean the iron filings or iron powder existing at the bottom of the steel plate body 12.

[0042] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown in the figure, each set of limiting components 4 includes a rack 41 fixed to the bottom of the connecting frame 25, a sleeve 45 rotatably mounted on one side of the support plate 13, and a gear 42 fixed to one end of the sleeve 45. The gear 42 meshes with the rack 41. An adapter ring 43 is fixed to the outside of the sleeve 45, and a limiting arc plate 44 is fixed to the outside of the adapter ring 43. One side of the limiting arc plate 44 is in contact with one side of the steel plate body 12. A T-shaped ring 46 is also fixedly sleeved on the outside of the sleeve 45. The T-shaped ring 46 has a T-shaped structure. A T-shaped groove for the T-shaped ring 46 to rotate is formed on one side of the support plate 13.

[0043] Through the above technical solutions:

[0044] When the stabilizing plate 22 is rising, first, the connecting frame 25 slides upward along one side of the support plate 13. The movement of the connecting frame 25 drives the movement of the rack 41. Then, the rack 41 meshes with the gear 42 for transmission, so as to drive the sleeve 45 to rotate along one side of the support plate 13. At this time, the rotation of the sleeve 45 drives the T-shaped ring 46 fixed to its outside to rotate in the T-shaped groove. However, the rotation of the sleeve 45 drives the adapter ring 43 to rotate. As the adapter ring 43 rotates, it drives the limiting arc plate 44 to rotate. Then, the limiting arc plate 44 arc-surrounds along one side of the support plate 13, so that the limiting arc plate 44 remains in contact with one side of the steel plate body 12.

[0045] Reference Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown in the figure, the disassembly and assembly component 6 includes positioning columns 66 fixed to the bottom ends of the two stabilizing plates 22, two chutes symmetrically formed at the top of the connecting frame 25 for the two positioning columns 66 to insert into, and a guiding groove 61 formed in the middle of the top of the connecting frame 25. Two slidable guiding blocks 62 are symmetrically installed in the guiding groove 61. A spring 63 is jointly installed between the two guiding blocks 62. Two pin slots 64 communicating with the inside of the two chutes are symmetrically formed in the guiding groove 61. Jack holes 67 are formed on the outside of the two positioning columns 66. Plug pins 65 are fixed to the opposite sides of the two guiding blocks 62. The two plug pins 65 are inserted into the two jack holes 67 corresponding to the two plug pins 65. Clamping components for positioning the two positioning columns 66 are provided in the two chutes. The clamping component includes a first fixed seat 68 fixed to the bottom wall inside the through groove and a second fixed seat 69 fixed to the bottom end of the positioning column 66. A concave tooth disc is fixed to the bottom end of the second fixed seat 69, and a convex tooth disc for inserting and pulling out the concave tooth is fixed to the top end of the first fixed seat 68.

[0046] A limiting block is also fixed in the guiding groove 61. A limiting slot is formed on one side of the guiding block 62, and the limiting slot is slidably connected with the limiting block.

[0047] Through the above technical solutions:

[0048] Before the stabilizer plate 22 is used, by placing both ends of the two stabilizer plates 22 on the top of the connecting frame 25, then pulling the two guiding blocks 62 and sliding them relatively along the guiding groove 61. At this time, the movement of the guiding block 62 drives the pin rod 65 to slide into the pin slot 64 along the sliding groove, retracting the part of the pin rod 65 in the sliding groove, and the positioning post 66 is inserted into the inside of the sliding groove. Moreover, the second fixing seat 69 slides downward along the sliding groove to plug the concave gear disk and the convex gear disk, that is, the second fixing seat 69 is plugged and fixed with the first fixing seat 68. After the second fixing seat 69 is fixed, the guiding block 62 is released. However, under the elastic force of the spring 63, the two guiding blocks 62 are pushed to slide towards each other along the guiding groove 61. As the sliding between the limiting groove and the limiting block, the pin rod 65 is then pushed to move from the pin slot 64 into the sliding groove. Subsequently, one end of the pin rod 65 located in the sliding groove is inserted into the jack 67, thus completing the installation operation of the stabilizer plate 22 on the connecting frame 25.
