Description

Technical Field

[0001] This invention relates to the field of punching equipment technology, specifically a punching machine with a movable base plate. Background Technology

[0002] Punching machines are commonly used equipment in the field of machining. They are mainly used to process holes with preset diameters and positions on workpieces. They are widely used in industries such as hardware processing, building materials production and machinery manufacturing. With the diversification of production needs, movable base plate punching machines have gradually replaced traditional fixed base plate punching machines and become one of the mainstream equipment because they can flexibly adjust the position of the workpiece and adapt to the punching needs of multiple positions.

[0003] The existing movable base plate punching machine uses ordinary slide rails with manual adjustment. Since it cannot limit the movement of the movable base plate around its perimeter, the movable base plate is prone to displacement. This causes the workpiece clamped and fixed on the movable base plate to shift, resulting in deviation of the workpiece punching position, scrapping of the workpiece during punching, affecting the product qualification rate, and thus reducing the processing accuracy of the movable base plate punching machine.

[0004] Combining the above issues, we find that existing movable base plate punching machines are difficult to avoid all of the problems mentioned above during use. Even if they can be solved, they require the use of external tools, which fails to achieve the desired effect. Therefore, we propose a movable base plate punching machine. Summary of the Invention

The side of each set of anti-slip positioning strips that is close to each other is in contact with the outer surface of the two anti-slip positioning rods.

[0010] Preferably, the inner wall of the supporting storage cabinet is fixedly connected to a partition plate, and two hinged doors are movably connected to one side of the supporting storage cabinet. One side of each of the hinged doors is in contact with one side of the partition plate, and a switch handle is fixedly connected to the other side of each of the hinged doors.

[0011] Preferably, a stabilizing bearing is fixedly connected to the inner bottom wall of the punching frame, and the outer surface of the rotating screw is fixedly connected to the inner ring of the stabilizing bearing.

[0012] Preferably, one side and the other side of the movable threaded block are both fixedly connected with threaded rings, and each threaded ring is threadedly connected to the outer surface of the rotating screw.

[0013] Preferably, the lateral manual limiting mechanism includes a lateral limiting frame, the bottom surface of which is fixedly connected to the upper surface of the moving plate. An electric push rod is fixedly connected to the inner wall of the lateral limiting frame, and a push block is fixedly connected to the telescopic end of the electric push rod. The push block is slidably connected inside the lateral limiting frame, and the bottom surface of the push block is in contact with the upper surface of the moving plate. A limiting bolt is rotatably connected inside the push block. Extrusion slots are provided on one side and the other side of the lateral limiting frame.

[0015] Preferably, the bottom surface of the supporting sliding plate is fixedly connected to two sets of movable legs, and the bottom end of each set of movable legs is fixedly connected to a caster wheel.

[0016] Preferably, a punching hydraulic rod is fixedly connected to the inner wall of the punching processing frame, and a damper is fixedly connected to the telescopic end of the punching hydraulic rod.

[0017] Preferably, a connecting head is fixedly connected to the bottom surface of the damper, and a punching head is connected to the internal thread of the connecting head.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention, by setting a longitudinal electric positioning mechanism, can conveniently store processing tools using a support storage cabinet fixed on a support sliding plate. It can also transport waste materials generated during processing from the connection point between the punching frame and the support storage cabinet to the support storage cabinet for collection. By controlling the power supply of the servo motor, the servo motor can be used to drive the rotating screw. Since a movable threaded block is connected to the external thread of the rotating screw, and a movable plate is fixed on the movable threaded block, and two support blocks are fixed below the movable plate in contact with the inner bottom wall of the punching frame, the rotating screw can drive the movable threaded block, along with the movable plate and... The support blocks move stably to facilitate precise adjustment of the longitudinal position of the workpiece until it reaches the appropriate position. Then, by controlling the electric telescopic rods fixed on one side of the two support blocks, the two anti-slip positioning rods are driven to extend into the snap-fit ​​grooves opened on the inner side wall of the punching frame. The anti-slip positioning rods press against the snap-fit ​​grooves, and anti-slip positioning strips are fixed on the inner bottom and inner top walls of the snap-fit ​​grooves to limit the movement of the anti-slip positioning rods. This facilitates the positioning of the longitudinal position of the workpiece, avoiding deviations in the punching position and preventing the workpiece from being scrapped during punching. This improves the processing accuracy of the movable punching machine with a base plate.

[0020] 2. This invention, by setting a lateral manual limiting mechanism, utilizes a lateral limiting frame fixed on the moving plate. An electric push rod fixed to the inner wall of the lateral limiting frame drives a pushing block to slide within the frame, thereby precisely adjusting the lateral position of the workpiece. Because extrusion slots are provided on both sides of the lateral limiting frame, the limiting bolt, carrying two extrusion cards, slides within the two extrusion slots while the pushing block moves within the frame. Once the appropriate position is reached, manually twisting the limiting bolt inside the pushing block and the nut outside it allows the limiting bolt and nut to press the extrusion cards in the two extrusion slots, ultimately positioning the pushing block within the lateral limiting frame. This facilitates precise lateral positioning of the workpiece, preventing workpiece punching position deviations and scrapping during punching, thus further improving the processing accuracy of the movable punching machine.

[0034] Please see Figure 1 and Figure 3 A partition 202 is fixedly connected to the inner wall of the supporting storage cabinet 201. Two hinged doors 203 are movably connected to one side of the supporting storage cabinet 201. One side of each door 203 is in contact with one side of the partition 202.

The partition 202 facilitates the separation and storage of waste materials and tools, while the switch handle 204 is held manually to facilitate opening and closing the door 203.

[0035] Please see Figure 2 A stabilizing bearing 211 is fixedly connected to the inner bottom wall of the punching frame 205. The outer surface of the rotating screw 210 is fixedly connected to the inner ring of the stabilizing bearing 211. The stabilizing bearing 211 guides the rotation of the rotating screw 210, thereby improving the rotational stability of the rotating screw 210.

[0036] Please see Figure 6One side and the other side of the movable threaded block 213 are fixedly connected with threaded rings 214. Each threaded ring 214 is threaded to the outer surface of the rotating screw 210. By using the threaded rings 214 on both sides of the movable threaded block 213, the threaded connection with the rotating screw 210 can be extended, thereby improving the stability of the threaded connection between the rotating screw 210 and the movable threaded block 213.

[0037] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A punching hydraulic rod 6 is fixedly connected to the inner wall of the punching processing frame 208. A damper 7 is fixedly connected to the telescopic end of the punching hydraulic rod 6. By fixing the punching hydraulic rod 6 to the inner wall of the punching processing frame 208, the power output by the punching hydraulic rod 6 can be used to punch the workpiece. The damper 7 can buffer the pressure of the workpiece reaction on the punching hydraulic rod 6.

[0038] Please see Figure 3 The bottom surface of the damper 7 is fixedly connected to the connecting head 8, and the internal thread of the connecting head 8 is connected to the punching head 9. The punching head 9 can be easily disassembled and replaced by manually rotating the connecting head 8, so as to facilitate punching the workpiece using different punching heads 9.

[0039] The specific implementation method of this embodiment is as follows: In use, first connect the power supply of the hydraulic oil valve of the servo motor 209, the electric telescopic rod 216, and the punching hydraulic rod 6. When the movable punching machine with this base plate needs to punch the workpiece, first use the support storage cabinet 201 fixed on the support sliding plate 1 to conveniently store the processing tools. It can also transport the waste generated during processing from the position where the punching processing frame 205 and the support storage cabinet 201 are connected to the support storage cabinet 201 for collection. The partition plate 202 is used to conveniently separate and store the waste and tools. Then, manually hold the switch handle 204 to... To facilitate opening and closing the switch door 203, the power supply of the servo motor 209 is controlled to drive the rotating screw 210. A stabilizing bearing 211 guides the rotation of the rotating screw 210, improving its stability. A movable threaded block 213 is threadedly connected to the external thread of the rotating screw 210. Threaded rings 214 on both sides of the movable threaded block 213 extend the threaded connection with the rotating screw 210, further improving the stability of the threaded connection. A movable plate 21 is fixed to the movable threaded block 213. 2. Two support blocks 215 are fixed under the moving plate 212 and contact the inner bottom wall of the punching frame 205. This allows the rotating screw 210 to drive the moving threaded block 213, which in turn moves the moving plate 212 and support blocks 215 stably. This facilitates precise adjustment of the longitudinal position of the workpiece until a suitable position is reached. Then, by controlling the electric telescopic rod 216 fixed to one side of the two support blocks 215, the two anti-slip positioning rods 217 are extended into the locking groove 206 opened on the inner side wall of the punching frame 205. The anti-slip positioning rods 217 then press against the locking groove 206, and the inner bottom of the locking groove 206... Anti-slip positioning strips 207 are fixed to the inner wall and the top wall to limit the movement of the anti-slip positioning rod 217, thereby facilitating the positioning of the longitudinal position of the workpiece and avoiding deviation in the punching position of the workpiece, which would cause the workpiece to be scrapped during punching. By fixing the punching hydraulic rod 6 to the inner wall of the punching frame 208, the power output by the punching hydraulic rod 6 can be used to punch the workpiece. The damper 7 can buffer the pressure of the workpiece reaction on the punching hydraulic rod 6. The punching head 9 can be easily disassembled and replaced by manually rotating the connecting head 8, so that different punching heads 9 can be used to punch the workpiece.

[0040] Example 2: Please refer to Figure 1 , Figure 5 , Figure 6 and Figure 7The present invention provides a technical solution: a movable base plate punching machine. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The lateral manual limiting mechanism 3 can accurately move the clamped workpiece laterally and manually limit the lateral movement of the workpiece.

[0041] As a further definition of the lateral manual limiting mechanism 3 of the present invention, the lateral manual limiting mechanism 3 includes a lateral limiting frame 301. The bottom surface of the lateral limiting frame 301 is fixedly connected to the upper surface of the moving plate 212. An electric push rod 302 is fixedly connected to the inner wall of the lateral limiting frame 301. A pushing block 303 is fixedly connected to the telescopic end of the electric push rod 302. The pushing block 303 is slidably connected to the inside of the lateral limiting frame 301. The bottom surface of the pushing block 303 is in contact with the upper surface of the moving plate 212. A limiting bolt 304 is rotatably connected inside the pushing block 303. One side and the other side of the lateral limiting frame 301 are both open. The device includes a compression slot 305, and two compression clips 306 are fitted on the outer surface of the limiting bolt 304. The two compression clips 306 are slidably connected to the inside of the two compression slots 305. A punching plate 308 is fixedly connected to the upper surface of the pushing block 303. The bottom surface of the punching plate 308 is in contact with the upper surface of the transverse limiting frame 301. An electric clamping claw 309 is fixedly connected to the inner wall of the punching plate 308. The electric clamping claw 309 is an automated actuator that uses a motor as a power source, converts rotational motion into clamping finger opening and closing action through a transmission mechanism, and achieves precise control of position, speed and clamping force through a closed-loop control system.

[0042] Please see Figure 7 A buffer pad 307 is fitted on the outer surface of the limiting bolt 304. One side of one of the extrusion cards 306 contacts one side of the buffer pad 307. By setting the buffer pad 307 on the side of the limiting bolt 304 that is close to the extrusion card 306, direct contact between the limiting bolt 304 and the extrusion card 306 can be avoided, thereby improving the service life of the extrusion card 306.

[0043] Please see Figure 1 and Figure 2 Two sets of movable legs 4 are fixedly connected to the bottom surface of the supporting sliding plate 1. Each set of movable legs 4 is fixedly connected to the bottom end of a caster wheel 5. The two sets of movable legs 4 and caster wheels 5 are used to form the moving structure of the movable punching machine, so that the movable punching machine can be moved to the required position.

[0044] The specific implementation of this embodiment is as follows: In use, the electric push rod 302 and the electric clamping jaw 309 are first connected to the power supply. When the movable base plate punching machine is needed to punch workpieces, the two sets of moving legs 4 and casters 5 are used to form the moving structure of the movable base plate punching machine, so that the movable base plate punching machine can be moved to the required position. The transverse limiting frame 301 is fixed on the moving plate 212, and the electric push rod 302 is fixed on the inner wall of the transverse limiting frame 301 to drive the pushing block 303 to slide within the transverse limiting frame 301, thereby accurately adjusting the transverse position of the workpiece. Since the extrusion grooves 305 are opened on both sides of the transverse limiting frame 301, the limiting bolts 305 can be used to press the pushing block 303 while it moves within the transverse limiting frame 301. 04. The two extrusion cards 306 slide within the two extrusion slots 305 until they reach the appropriate position. Then, by manually twisting the limiting bolt 304 inside the push block 303 and the nut outside the limiting bolt 304, the limiting bolt 304 and the nut can easily engage to extrude the extrusion cards 306 within the two extrusion slots 305. By setting a buffer pad 307 on the side of the limiting bolt 304 that is close to the extrusion card 306, direct contact between the limiting bolt 304 and the extrusion card 306 can be avoided, thereby improving the service life of the extrusion card 306. This allows the push block 303 within the transverse limiting frame 301 to be positioned and extruded, thus facilitating the transverse positioning of the workpiece and preventing deviations in the punching position, which could lead to the scrapping of the workpiece.

[0045] Example 3: Specifically, when this movable punching machine for the base plate is working / in use:

[0046] First, connect the power supply to the hydraulic oil valves of the servo motor 209, electric telescopic rod 216, and punching hydraulic rod 6. When using this movable punching machine to punch workpieces, first use the support storage cabinet 201 fixed on the support sliding plate 1 to conveniently store the processing tools. It also allows waste materials generated during processing to be transported from the punching frame 205 to the support storage cabinet 201 for collection. The partition 202 facilitates the separation and storage of waste materials and tools. The switch handle 204 is held manually to easily open and close the switch door 203. Controlling the power supply of the servo motor 209 allows it to drive the rotating screw. The rotating screw 210 rotates, and the rotation of the rotating screw 210 is guided by the stabilizing bearing 211, thereby improving the rotational stability of the rotating screw 210. Since the rotating screw 210 is externally threaded to the movable threaded block 213, the threaded connection with the rotating screw 210 is extended by the threaded rings 214 on both sides of the movable threaded block 213, thereby improving the stability of the threaded connection between the rotating screw 210 and the movable threaded block 213. A movable plate 212 is fixed on the movable threaded block 213, and two support blocks 215 are fixed below the movable plate 212, contacting the inner bottom wall of the punching frame 205. Thus, the rotating screw 210 can drive the movable threaded block 213, along with the movable plate 212 and the support blocks 214. 15. Stable movement facilitates precise adjustment of the longitudinal position of the workpiece until a suitable position is reached. Then, by controlling the electric telescopic rods 216 fixed to one side of the two support blocks 215, two anti-slip positioning rods 217 are extended into the locking grooves 206 opened on the inner wall of the punching frame 205. The anti-slip positioning rods 217 press against the locking grooves 206, and anti-slip positioning strips 207 are fixed to the inner bottom and top walls of the locking grooves 206 to limit the movement of the anti-slip positioning rods 217. This facilitates the positioning of the longitudinal position of the workpiece, preventing workpiece punching position deviation and scrapping during punching. A punching hydraulic rod 6 is fixed to the inner wall of the punching frame 208. The machine can use the power output of the punching hydraulic rod 6 to punch the workpiece. The damper 7 buffers the pressure exerted by the workpiece reaction on the punching hydraulic rod 6. The punching head 9 can be easily disassembled and replaced by manually rotating the connecting head 8, allowing for the use of different punching heads 9 to punch the workpiece. In use, the electric push rod 302 and electric clamping jaw 309 are first connected to the power supply. When the machine needs to punch the workpiece, two sets of moving legs 4 and casters 5 are used to form the moving structure of the machine, allowing it to be moved to the desired position. The transverse limiting frame 301 fixed on the moving plate 212 further facilitates this process.By fixing an electric push rod 302 to the inner wall of the transverse limiting frame 301, the pushing block 303 is driven to slide within the transverse limiting frame 301, thereby precisely adjusting the transverse position of the workpiece. Because extrusion slots 305 are provided on both sides of the transverse limiting frame 301, the limiting bolt 304, carrying two extrusion clips 306, slides within the two extrusion slots 305 while the pushing block 303 moves within the transverse limiting frame 301, until the appropriate position is reached. Then, by manually twisting the limiting bolt 304 inside the pushing block 303 and the nut outside the limiting bolt 304, the workpiece can be precisely adjusted. The mechanism allows the limiting bolt 304 and nut to easily press the extrusion cards 306 within the two extrusion slots 305. By providing a buffer pad 307 on the side of the limiting bolt 304 closest to the extrusion card 306, direct contact between the limiting bolt 304 and the extrusion card 306 is avoided, thus extending the service life of the extrusion card 306. This allows for positioning and pressing of the pushing block 303 within the transverse limiting frame 301, facilitating the transverse positioning of the workpiece and preventing workpiece punching position deviations that could lead to workpiece scrap during punching.
