Description

Technical Field

[0001] This utility model belongs to the technical field of square tube punching equipment, and in particular relates to a square tube punching equipment. Background Technology

[0002] Square tube punching equipment is an automated or semi-automated mechanical device specifically designed for processing square or rectangular metal tubes. Its core function is to precisely punch openings, holes, grooves, or notches of specific shapes at designated positions on the square tube through the combined action of molds and punching force, in order to meet the needs of subsequent assembly, connection, or structural functions. This equipment usually integrates modules such as feeding and positioning, punching execution, and finished product unloading. It can be adapted to different molds and parameter settings according to the material, specifications, punching size, and shape differences of the square tube.

[0003] However, in the process of using existing equipment, the punching molds equipped with it can only perform stamping processing on punches of fixed sizes. But in actual production scenarios, the processing requirements for square tube punches are often diverse. Different projects and different assembly scenarios have different standards for key parameters such as the width, depth, and diameter of square tube punches. This fixed-size mold design makes it difficult for the equipment to flexibly adapt to diverse processing requirements, which to some extent limits production flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a square tube punching device. By setting up a replacement part, it solves the problem that the punching mold equipped with it can only perform punching processing for punches of fixed size. However, in actual production scenarios, the processing requirements for square tube punching are often diverse. Different project requirements and different assembly scenarios have different standards for key parameters such as the width, depth, and diameter of square tube punches. This fixed-size mold design makes it difficult for the device to flexibly adapt to diverse processing requirements, which to some extent limits the problem of production flexibility.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a square tube punching device, comprising a mounting plate, and further comprising: a replacement part disposed on the mounting plate; a feeding part disposed at the bottom of the mounting plate; the replacement part comprising a replacement assembly disposed on the mounting plate; an adjustment assembly disposed at the bottom of the mounting plate; and a processing assembly disposed on the mounting plate; the replacement assembly comprising a sliding frame fixedly connected to the bottom of the mounting plate, a slider slidably connected within the sliding frame, a mold slidably connected to the front of the slider, two screws fixedly connected to the front of the slider, a limit plate slidably connected to the outer wall of the two screws, two insert rods fixedly connected to the back of the limit plate, and nuts threadedly connected to the outer wall of each of the two screws; a driving component disposed at the bottom of the mounting plate, the rear ends of the two insert rods extending into the mold and slidably connected to the mold; the driving component comprising a hydraulic push rod fixedly connected to the bottom of the mounting plate, the output end of the hydraulic push rod being fixedly connected to the slider, and the hydraulic push rod being located on the back of the slider.

[0007] Furthermore, the feeding section includes a fixing component disposed at the bottom of the mounting plate; and a pushing component mounted on the fixing component.

[0008] Furthermore, the adjustment assembly includes a workbench located at the bottom of the mounting plate, a mounting frame fixedly connected to the top of the workbench, a bidirectional screw rotatably connected to the mounting frame, two adjustment templates threadedly connected to the outer wall of the bidirectional screw, both adjustment templates being slidably connected to the mounting frame, a square tube being provided on the side of the two adjustment templates that are close to each other, a limit component being provided on the mounting frame, the front end of the bidirectional screw extending outside the mounting frame and rotatably connected to the mounting frame, the workbench at the bottom of the mounting plate providing stable support for the overall structure, and the mounting frame at the top providing the mounting base for the bidirectional screw and adjustment templates, the rotation of the bidirectional screw driving the two adjustment templates on the outer wall to slide relative to or towards each other within the mounting frame, flexibly adjusting the spacing to adapt to square tubes of different specifications, solving the limitation of a single template in adapting to tube materials.

[0009] Furthermore, the processing assembly includes a slide fixedly connected to the top of the worktable. The slide passes through the mounting plate and is slidably connected to the mounting plate. A second hydraulic push rod is fixedly connected to the top of the slide. The output end of the second hydraulic push rod is fixedly connected to the mounting plate and extends to the outside of the slide, where it is slidably connected. The slide at the top of the worktable passes through the mounting plate and forms a sliding guide, ensuring that the mounting plate moves smoothly along a fixed path when lifting and lowering the relevant processing components, avoiding deviation that could affect processing accuracy. The second hydraulic push rod at the top of the slide can drive the mounting plate to precisely adjust its height. By adapting the lifting stroke through the sliding connection at its output end, the distance between the processing components and the square tube below can be flexibly controlled to meet different processing depths or operational requirements.

[0010] Furthermore, the fixing assembly includes two slide rails fixedly connected to the top of the workbench. Slide plates are slidably connected to the outer surfaces of the two slide rails. Two rectangular plates are fixedly connected to the top of the slide plates. Two sliding rods are fixedly connected to the sides of the two rectangular plates that are close to each other. Two sliders are slidably connected to the outer walls of the two sliding rods. Positioning plates are fixedly connected to the bottoms of the two sliders. Fixing blocks are fixedly connected to the outer walls of the two sliding rods. A connecting rod is rotatably connected to the top of the fixing blocks. Connecting rods are hinged to the ends of the connecting rods that are far apart from each other. The ends of the two connecting rods that are far apart from the connecting rods are hinged to the two sliders. A driving component is provided on the corresponding rectangular plate. The sides of the two positioning plates that are close to each other are in contact with the square tube. The driving component includes a hydraulic push rod fixedly connected to the corresponding rectangular plate. The hydraulic push rod passes through the corresponding rectangular plate and is slidably connected to it. The output end of the hydraulic push rod is fixedly connected to the corresponding positioning plate. The hydraulic push rod is located on the front rectangular plate.

[0011] Furthermore, the pushing assembly includes two rectangular plates fixedly connected to the bottom of the mounting plate. A motor is fixedly connected to each rectangular plate, and the output shaft of the motor is fixedly connected to a screw rod via a coupling. The screw rod passes through the two rectangular plates and is rotatably connected to them. A connecting block is threaded onto the outer wall of the screw rod, and the top of the connecting block extends out of the mounting plate and is fixedly connected to the slide plate. A balance bar is fixedly connected to one side of the two rectangular plates that are close to each other. The balance bar passes through the connecting block and is slidably connected to it. The two rectangular plates at the bottom of the mounting plate provide a stable mounting foundation for the motor and the screw rod, ensuring stable operation of the power components. The motor drives the screw rod to rotate via the coupling, which in turn moves the threaded connecting block, thereby triggering the slide plate to push the material. This eliminates the need for manual operation and improves the degree of automation.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a replacement section, when it is necessary to change the mold according to the size of the square tube, use tools to remove the nuts on the two screws, take out the limiting plate and the insert rod, and then replace the mold in the slider. When installing, follow the reverse steps. After the mold is replaced, rotate the bidirectional screw on the mounting frame to move the two adjusting templates closer or further away to adapt to the new mold size. After adjustment, rotate the nuts on the outer wall of the screw on the adjusting template outward to make it cooperate with the limiting and fixing screw on the mounting frame to avoid uneven force on the adjusting template, which may cause punching failure. This setting can realize quick mold replacement and precise adaptation of the adjusting template, allowing the device to flexibly meet the punching needs of square tubes of different sizes, and improve the equipment's versatility and processing stability.

[0014] 2. By setting up a feeding section, when punching square tubes, first pass the square tube through the two adjusting templates on the mounting frame, and place the protruding end on the sliding plate. Activate hydraulic push rod three to push the positioning plate and slider two to slide inward. Because the connecting rod two, which is hinged to slider two, is hinged to the connecting rod one on the fixed block, the transmission between connecting rod two, connecting rod one, and slider two at the other end causes the two sliders two on the outer wall of the sliding rod to drive the rectangular plate one to move closer to each other, firmly clamping the square tube. After clamping in place, activate hydraulic push rod two, and with the help of the slide, drive the mounting plate and mold deeper into the square tube. Then activate hydraulic push rod one, and through slider one, drive the mold to move back and forth, cutting off the front and rear side walls of the square tube to complete the punching. When subsequent processes are needed, start the motor, and through screw three and balance rod, drive the connecting block to move the square tube to the right to achieve automatic feeding. This setting can realize the automated clamping, processing, and feeding of square tube punching, greatly improving processing efficiency and operation convenience.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 As shown, this utility model is a square tube punching device, including: a mounting plate 1, and further including: a replacement part 2, which is disposed on the mounting plate 1; and a feeding part 3, which is disposed at the bottom of the mounting plate 1.

[0026] The replacement unit 2 includes a replacement component 21, which is mounted on the mounting plate 1; an adjustment component 22, which is located at the bottom of the mounting plate 1; and a processing component 23, which is also located on the mounting plate 1. The replacement component 21 includes a sliding frame 211 fixedly connected to the bottom of the mounting plate 1. A slider 212 is slidably connected inside the sliding frame 211. A mold 213 is slidably connected to the front of the slider 212. Two screws 214 are fixedly connected to the front of the slider 212. A limit plate 215 is slidably connected to the outer wall of the two screws 214. Two insert rods 216 are fixedly connected to the back of the limit plate 215. Nuts 217 are threaded onto the outer wall of each screw 214. A drive component and two insert rods are located at the bottom of the mounting plate 1. The rear ends of 216 all extend into the mold 213 and are slidably connected to the mold 213. The adjustment component 22 includes a worktable 221 set at the bottom of the mounting plate 1. A mounting frame 222 is fixedly connected to the top of the worktable 221. A bidirectional screw 223 is rotatably connected to the mounting frame 222. Two adjustment templates 224 are threadedly connected to the outer wall of the bidirectional screw 223. Both adjustment templates 224 are slidably connected to the mounting frame 222. A square tube 225 is set on the side of the two adjustment templates 224 that are close to each other. A limit component is set on the mounting frame 222. The front end of the bidirectional screw 223 extends outside the mounting frame 222 and is rotatably connected to the mounting frame 222. The processing component 23 includes a slide 231 fixedly connected to the top of the worktable 221. The slide 231 passes through... Mounting plate 1 is slidably connected to mounting plate 1. A hydraulic push rod 232 is fixedly connected to the top of slide 231. The output end of hydraulic push rod 232 is fixedly connected to mounting plate 1.

Hydraulic push rod 218 is located on the back of slider 212. By setting replacement part 2, if it is necessary to change mold 213 according to the size of square tube 225 during use, tools can be used to remove nuts 217 on two screws 214. After the two nuts 217 are removed, the limiting plate 215 and its upper part can be installed. The two insert rods 216 are removed from the mold 213 and the two screws 214. At this time, the mold 213, which is slidably connected inside the slider 212, can be replaced. After the mold 213 is replaced, the assembly is performed in the reverse order of disassembly. After the mold is ready, the bidirectional screw 223 on the mounting frame 222 can be rotated. The bidirectional screw 223 will drive the two adjusting templates 224 to move closer or further apart to match the size of the replaced mold 213. When the two adjusting templates 224 are adjusted to the appropriate position, the nut 227 on the outer wall of the screw 226 on the two adjusting templates 224 is rotated outward with a tool. The nut 227 cooperates with the mounting frame 222 to limit and fix the screw 226 on the adjusting template 224.To prevent punching failure due to uneven force on the two adjusting templates 224 during the square tube punching process, this design allows for rapid mold replacement and precise template adaptation. This enables the equipment to flexibly handle the punching requirements of square tubes of different sizes, effectively improving the equipment's versatility and processing stability.

[0027] The feeding section 3 includes a fixing component 31, which is disposed at the bottom of the mounting plate 1; and a pushing component 32, which is mounted on the fixing component 31. The fixing component 31 includes two slide rails 311 fixedly connected to the top of the worktable 221. Slide plates 312 are slidably connected to the outer surfaces of the two slide rails 311. Two rectangular plates 313 are fixedly connected to the top of the slide plates 312. Two sliding rods 314 are fixedly connected to the side of the two rectangular plates 313 that are close to each other. Two sliders 315 are slidably connected to the outer walls of the two sliders 314. Positioning plates 316 are fixedly connected to the bottom of each slider 315. Fixing blocks 317 are fixedly connected to the outer walls of the two sliders 314. A connecting rod 318 is rotatably connected to the top of the fixing blocks 317. Each connecting rod 318 has a connecting rod 319 hinged to its opposite ends. The ends of the two connecting rods 319 away from the connecting rod 318 are hinged to two sliders 315. A driving component 2 is provided on the corresponding rectangular plate 313. The sides of the two positioning plates 316 that are close to each other are in contact with the square tube 225. The pushing assembly 32 includes two rectangular plates 321 fixedly connected to the bottom of the mounting plate 1. A motor 322 is fixedly connected to the corresponding rectangular plate 321. The output shaft of the motor 322 is fixedly connected to a screw 323 via a coupling. The screw 323 passes through the two rectangular plates 321 and is rotatably connected to them. A connecting block 324 is threaded onto the outer wall of the screw 323, and the top of the connecting block 324 extends... The mounting plate 1 is fixedly connected to the slide plate 312. A balance bar 325 is fixedly connected to one side of the two rectangular plates 321 that are close to each other. The balance bar 325 passes through the connecting block 324 and is slidably connected to the connecting block 324. The driving component 2 includes a hydraulic push rod 320 fixedly connected to the corresponding rectangular plate 313. The hydraulic push rod 320 passes through the corresponding rectangular plate 313 and is slidably connected to the corresponding rectangular plate 313. The output end of the hydraulic push rod 320 is fixedly connected to the corresponding positioning plate 316. The hydraulic push rod 320 is located on the front rectangular plate 313. By setting the feeding part 3, if it is necessary to punch the square tube 225 during use, the square tube 225 can be first passed through the two adjusting templates 224 on the mounting frame 222, and the protruding part... One end is placed on the slide plate 312. After placement, the hydraulic push rod 320 is activated, which pushes the positioning plate 316 and its slider 315 sliding inward on one side of the slide rod 314. Since the slider 315 is hinged to the connecting rod 319, and the other end of the connecting rod 319 is hinged to the connecting rod 318 rotatably connected to the fixed block 317, during the process of the hydraulic push rod 320 pushing the positioning plate 316 inward, the connecting rod 319 and the connecting rod 318 at the top of the slider 315 can form a transmission with the connecting rod 319 on the other end of the slide rod 314, causing the two sliders 315 on the outer wall of the slide rod 314 to drive the rectangular plates 313 on them to move closer to each other.This system securely clamps the internal square tube 225. Once the square tube 225 is in place, if punching is required, hydraulic push rod 232 can be activated. Hydraulic push rod 232, via slide 231, will drive mounting plate 1 and mold 213 on the plate into the square tube 225 on mounting frame 222. Then, hydraulic push rod 218 is activated, which, via slider 212, will move mold 213 back and forth to cut off the front and rear sidewalls of the square tube 225, thus achieving the square tube punching operation. If subsequent punching processes are required, motor 322 can be activated. Motor 322, via screw 323 and balance bar 325, will drive connecting block 324 to move the square tube 225 clamped on mounting plate 1 to the right, achieving automatic feeding of the square tube. This system enables automated clamping, processing, and feeding of square tube punching, significantly improving processing efficiency and ease of operation.

[0028] It should be noted that the control of motor 322, hydraulic push rod 1 218, hydraulic push rod 232 and hydraulic push rod 320 in this application can all be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0029] A specific application of this embodiment is as follows: When using the square tube 225, if punching is required, the square tube 225 can be passed through the two adjusting templates 224 on the mounting frame 222, and the protruding end can be placed on the sliding plate 312. After placement, the hydraulic push rod 320 is activated, which will push the positioning plate 316 sliding on one side of the slide rod 314 and its slider 315 to slide inward. Since the slider 315 is hinged with the connecting rod 319, and the other end of the connecting rod 319 is hinged to the connecting rod 318 rotatably connected to the fixed block 317, during the process of the hydraulic push rod 320 pushing the positioning plate 316 on one side to move inward, the connecting rod 319 and the connecting rod 318 at the top of the slider 315 can form a transmission with the connecting rod 319 on the other end of the slide rod 314, so that the two sliders 315 on the outer wall of the slide rod 314 can respectively drive the rectangular plate 31 on it. 3. The components move closer together to securely clamp the square tube 225 inside. Once the square tube 225 is clamped in place, if punching is required, hydraulic push rod 232 can be activated. Hydraulic push rod 232 will use slide 231 to drive mounting plate 1 and mold 213 on the plate into the square tube 225 on mounting frame 222. Then, hydraulic push rod 218 will be activated. Hydraulic push rod 218 will drive mold 213 to move back and forth through slider 212 to cut off the front and rear side walls of the square tube 225, thus achieving the square tube punching operation. If subsequent punching processes are required, motor 322 can be activated. Motor 322 will drive connecting block 324 through screw 323 and balance bar 325 to move the square tube 225 clamped on mounting plate 1 to the right, realizing automatic feeding of square tube. With this setup, the automatic clamping, processing and feeding of square tube punching can be realized, greatly improving processing efficiency and ease of operation.If the mold 213 needs to be replaced according to the size of the square tube 225 during use, tools can be used to remove the nuts 217 on the two screws 214. After the two nuts 217 are removed, the limiting plate 215 and its two inserts 216 can be removed from the mold 213 and the two screws 214. At this time, the mold 213 slidably connected in the slider 212 can be replaced. After the mold 213 is replaced, the assembly is performed by following the reverse steps of disassembly. After the mold is ready, the bidirectional screw 223 on the mounting frame 222 can be rotated. The bidirectional screw 223 will drive the two adjusting templates 224 to move closer together. The two adjusting templates 224 are adjusted to fit the size of the replaced mold 213, either close or far apart. Once the two adjusting templates 224 are in the appropriate position, the nuts 227 on the outer wall of the screws 226 on the two adjusting templates 224 are rotated outwards using a tool. This allows the nuts 227 to engage with the mounting frame 222 to limit and fix the screws 226 on the adjusting templates 224, preventing uneven force on the two adjusting templates 224 during the square tube punching process, which could lead to punching failure. This design allows for quick mold replacement and precise adaptation of the adjusting templates, enabling the device to flexibly handle the punching requirements of square tubes of different sizes, effectively improving the equipment's versatility and processing stability.
