Description

Technical Field

[0001] The invention belongs to the technical field of hole punching machines, in particular to a stainless steel pipe hole punching machine. Background Art

[0002] Stainless steel pipes are widely used because of their excellent corrosion resistance and mechanical properties. During the use of stainless steel pipes, drilling operations are often required. At this time, a hole punching machine is required. However, when drilling holes in thin stainless steel pipes, due to the thin thickness of the steel pipe itself, it is easy to collapse and deform under the pressure of the drill bit, resulting in deviations between the punched holes and the actual requirements.

[0003] After searching, a Chinese patent with the announcement number CN116441594B discloses a stainless steel pipe body hole opening machine, including a workbench, on which a frame is provided; the frame is provided with a drilling assembly; the drilling assembly includes a No. 1 cylinder, the output end of the No. 1 cylinder is fixedly connected to a drilling motor, the output end of the drilling motor is fixedly connected to a drill rod, and a pipe body support assembly is provided below the drill rod; the present invention, through the setting of the pipe body support assembly, adjusts the diameter of the circle surrounded by multiple top plates by the outward offset of the top plate, and presses against the surface of the stainless steel pipe, intermittently enhancing the performance of the stainless steel pipe in resisting external extrusion pressure, and at the same time, when supporting and pressing the stainless steel pipe, the top plate will also stabilize the stainless steel pipe, preventing the problem that the position point to be punched on the stainless steel pipe deviates from the axis of the drill bit, thereby improving the quality of the hole opening on the stainless steel pipe body.

[0004] In the above technology, although the inner wall of the stainless steel pipe is supported by the design of the top plate, thereby avoiding collapse and deformation due to the thin thickness of the stainless steel pipe during the hole opening process, when the above hole opening machine is actually used, in order to realize the support of the inner wall of the steel pipe by the top plate, it is necessary to let the base squeeze the plug in the support assembly, thereby driving the extrusion plates at both ends of the support assembly to approach each other. When the extrusion plates at both ends are close to each other, the top plate can be lifted up to achieve support for the inner wall of the stainless steel pipe. However, this method is only suitable for steel pipes whose length is less than the length of the support assembly. For steel pipes with longer lengths, the base cannot contact the plug in the support assembly, and thus cannot support the steel pipe. At the same time, since the chip removal hole in the support assembly is set in the middle of the top plate, this results in the hole opening machine being able to only open holes in the middle of the steel pipe, thereby reducing the applicability of the hole opening machine.

[0005] To this end, the present invention provides a stainless steel pipe hole opening machine. Summary of the invention

[0022] 1. A stainless steel pipe hole-opening machine described in the present invention supports and fixes one end of a stainless steel pipe by designing a fixing mechanism, wherein four first extrusion plates are driven to move respectively by four first electric push rods, thereby extruding the inner wall of one end of the steel pipe, thereby fixing the steel pipe, and further supporting and fixing the other end of the steel pipe by arranging a second electric push rod and a second extrusion plate on the moving plate, wherein the moving plate can move under the drive of a third motor, thereby fixing steel pipes of different lengths, and further supporting the position where the inner wall of the steel pipe needs to be opened by designing an inner support mechanism, thereby avoiding the situation where the steel pipe is too thin and causes collapse and deformation during the hole-opening process;

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] like Figures 1 to 16 As shown, a stainless steel pipe hole opening machine described in an embodiment of the present invention comprises: a workbench 1; a fixing mechanism 2, which is arranged at one end of the top of the workbench 1; an inner support mechanism 3, which is arranged at one end of the top of the fixing mechanism 2; the fixing mechanism 2 comprises a fixing plate 201, a first rotating disk 202, a first mounting block 204 and a first electric push rod 205, the fixing plate 201 is fixedly connected to one end of the top of the workbench 1, one end of the side wall of the fixing plate 201 is rotatably connected to the first rotating disk 202, one end of the side wall of the first rotating disk 202 is fixedly connected to a first limiting plate 203, one end of the side wall of the first limiting plate 203 is fixedly connected to the first mounting block 204, the side walls around the first mounting block 204 are respectively fixedly connected to the first electric push rods 205, and the output end of the first electric push rod 205 is fixedly connected to the first extrusion plate 206;

[0045] The inner support mechanism 3 includes a first cylinder 301, a support rod 302 and a material storage barrel 303. The first cylinder 301 is fixedly connected to the fixed plate 201 and is located on the side wall of the fixed plate 201 away from the first rotating disk 202. The output end of the first cylinder 301 is fixedly connected to the support rod 302. The support rod 302 is slidably connected to the fixed plate 201, the first rotating disk 202, the first limit plate 203 and the first mounting block 204. One end of the support rod 302 is fixedly connected to the material storage barrel 303. The interior of the material storage barrel 303 is divided into a driving chamber 305 and a material storage chamber 306 by a partition plate 304. The material storage barrel 303 is located at the top of one end of the material storage chamber 306 and is provided with a first sleeve 307. A sliding tube 308 is slidably connected in the first sleeve 307. A first inner support plate 309 is fixedly connected to the top of the tube 308, and a material receiving hole 310 is provided on the first inner support plate 309 at the sliding tube 308. The sliding tube 308 is fixedly connected to a first connecting rod 311 at one end of the material storage chamber 306, and a linear guide groove 312 is provided at the first connecting rod 311 of the partition plate 304. The first connecting rod 311 is slidably connected to the linear guide groove 312. The material storage barrel 303 is fixedly connected to a first motor 313 in the driving chamber 305, and a guide plate 314 is fixedly connected to the output end of the first motor 313. Four arc-shaped guide grooves 315 are evenly opened in the middle of the guide plate 314. A first slider 316 is fixedly connected to one end of the first connecting rod 311, and the first slider 316 is slidably connected to the arc-shaped guide groove 315.

[0046] In this embodiment, since the thin stainless steel pipe is prone to collapse and deformation during the hole opening process, which may cause the hole to deviate from the actual requirements, it is necessary to support the inner wall of the steel pipe during the hole opening process. During operation, one end of the steel pipe is first sleeved on the first mounting block 204 on the fixing mechanism 2, and then the four first electric push rods 205 are opened, thereby driving the four first extrusion plates 206 to move respectively, so that the four extrusion plates support the inner wall of one end of the steel pipe, thereby fixing the steel pipe, and then the first cylinder 301 is opened. Under the drive of the first cylinder 301, the storage barrel 303 will move along the length direction of the steel pipe. The first inner support plate 309 is moved along the length direction of the steel pipe. When the first inner support plate 309 moves to the hole opening position, the first motor 313 is turned on. Under the drive of the first motor 313, the guide plate 314 rotates, thereby driving the first slider 316 to move along the arc guide groove 315, thereby driving the first connecting rod 311 to move, wherein the first connecting rod 311 is limited by the linear guide groove 312, so that the first connecting rod 311 can only move up and down along the linear guide groove 312, thereby driving the sliding tube 308 to move up and down, and then driving the first inner support plate 309 to move up and down, so as to support the position where the hole is to be opened on the inner wall of the steel pipe. During operation, the material receiving hole 310 on the first inner support plate 309 is exactly located at the hole position of the opening. Since the first motor 313 and the guide plate 314 are both installed in the driving cavity 305, driving the first inner support plate 309 to move in this way can increase the internal space of the material storage cavity 306. If the first inner support plate 309 is driven to move directly by a driving mechanism such as a cylinder or a motor, the motor or cylinder needs to be installed on the same axis as the first sleeve 307 and needs to be installed inside the material storage barrel 306. This will not only occupy the internal space of the material storage cavity 306, but also the internal space of the material storage cavity 306 is limited. If the motor or cylinder is installed inside the material storage cavity 306, it will also shrink The stroke of the first inner support plate 309 is shortened, and a hole can be drilled in the steel pipe. The hole drilling method can be carried out by drilling with an electric drill. When the electric drill applies pressure to the steel pipe during the hole drilling, the first inner support plate 309 supports the inner wall of the steel pipe at the hole drilling position. Therefore, when the hole is drilled, the part of the steel pipe located at the hole drilling position will not collapse, thereby ensuring the accuracy of the hole drilling position. During the hole drilling process, the end of the electric drill will pass through the steel pipe and extend to the slide tube 308 through the material receiving hole 310. At the same time, the debris generated will enter the storage barrel 303 through the material receiving hole 310, the slide tube 308 and the first sleeve 307, so as to facilitate subsequent cleaning.

[0047] like Figure 4 As shown, the fixed plate 201 is located above the first cylinder 301 and is fixedly connected to the second motor 207, the output end of the second motor 207 is fixedly connected to the gear 208, the side wall of the first rotating disk 202 is fixedly connected to the gear ring 209, and the gear 208 is meshed with the gear ring 209;

[0048] In this embodiment, the gear 208 is driven to rotate by the second motor 207, thereby driving the first turntable 202 to rotate, and then driving the steel pipe to rotate. During the rotation of the steel pipe, the first inner support plate 309 needs to be driven downward by the first motor 313 so that the first inner support plate 309 does not affect the rotation of the steel pipe and is always in an upward state. When the steel pipe has rotated well, the first inner support plate 309 is driven again by the first motor 313 to support the inner wall of the steel pipe. In this way, it is convenient to open holes in the circumference of the steel pipe.

[0049] like Figures 5 to 9 As shown, the material storage barrel 303 is evenly provided with three second sleeves 317 below the first sleeve 307, a sliding rod 318 is slidably connected in the second sleeve 317, one end of the sliding rod 318 is fixedly connected to a second inner support plate 319, the sliding rod 318 is located at one end of the material storage chamber 306 and is fixedly connected to a second connecting rod 320, the second connecting rod 320 is slidably connected to the linear guide groove 312, one end of the second connecting rod 320 is fixedly connected to a second slider 321, and the second slider 321 is slidably connected to the arc guide groove 315;

[0050] In this embodiment, the second slider 321 and the second connecting rod 320 are designed so that when the first motor 313 drives the guide plate 314 to rotate, the second slider 321 will move along the arc guide groove 315, thereby driving the connecting rod to move, wherein the connecting rod is limited by the linear guide groove 312, so it can only move along the direction of the linear guide groove 312, and the lower slide bar 318 will move under the drive of the second connecting rod 320, thereby driving the second inner support plate 319 to move, so that the second inner support plate 319 supports the inner wall of the steel pipe, thereby improving the steel pipe when opening the hole. Stability, wherein the first inner support plate 309 has only one more material receiving hole 310 compared to the second inner support plate 319, and the rest of the structure is exactly the same, and the first inner support plate 309 and the three second inner support plates 319 will move driven by the guide plate 314, and the guide plate 314 will rotate driven by the first motor 313. Therefore, in this way, a first motor 313 can simultaneously drive a first inner support plate 309 and three second inner support plates 319 to move, so that the first inner support plate 309 and the three and second inner support plates 319 can move synchronously.

[0052] In this embodiment, by moving the movable plate 4 to the end of the steel pipe away from the fixed plate 201, and allowing one end of the steel pipe to be mounted on the second mounting block 403, the four second electric push rods 404 are turned on to drive the four second extrusion plates 405 to move respectively. Under the extrusion of the four second extrusion plates 405, the end of the steel pipe away from the fixed plate 201 can be fixed, thereby ensuring the stability of the steel pipe when opening a hole.

[0059] like Figure 12 to Figure 13 As shown, one end of the dust suction pipe 502 is connected to a docking joint 504, one end of the docking joint 504 is provided with a tapered groove 505 that fits with the tapered pipe 322, and the docking joint 504 is provided with a plug hole 506 at one end of the tapered groove 505, and the plug-in pipe 323 is movably plugged with the plug hole 506;

[0060] In this embodiment, the design of the conical groove 505 and the plug hole 506 makes it easier for the plug-in tube 323 to be plugged into the dust suction tube 502 , thereby facilitating the vacuum cleaner 501 to absorb the debris inside the storage barrel 303 .

[0061] like Figure 1 , Figure 2 and Fig.16 As shown, a support frame 6 is fixedly connected to the top of the workbench 1, a fourth cylinder 601 is slidably connected to the top of the support frame 6, a fourth motor 602 is fixedly connected to the output end of the fourth cylinder 601, and a drill bit 603 is fixedly connected to the output end of the fourth motor 602;

[0062] In this embodiment, the drill bit 603 can be driven to move up and down through the design of the fourth cylinder 601, and the drill bit 603 can be driven to rotate through the fourth motor 602, so that the drill bit 603 can smoothly drill a hole in the steel pipe.

[0063] like Figure 1 , Figure 2 and Fig.16 As shown, a through slot 604 is provided on the top of the support frame 6, a connecting block 605 is fixedly connected to the top of the fourth cylinder 601, the connecting block 605 is slidably connected to the through slot 604, a fifth motor 606 is fixedly connected to the top of the support frame 6 at one end of the through slot 604, a second screw rod 607 is fixedly connected to the output end of the fifth motor 606, a collar 608 is fixedly connected to the top of the connecting block 605, and the second screw rod 607 is threadedly connected to the collar 608;

[0064] In this embodiment, the fifth motor 606 is designed to drive the second screw rod 607 to rotate, thereby driving the connecting block 605 to move along the through groove 604, that is, the length direction of the steel pipe, and then driving the drill bit 603 to move along the length direction of the steel pipe, so that the drill bit 603 can move to the position of all holes.

[0065] Working principle: When in use, first put one end of the steel pipe on the first mounting block 204, then open the four first electric push rods 205, thereby driving the four first extrusion plates 206 to move, and under the extrusion of the four first extrusion plates 206, one end of the steel pipe will be fixed, and then the third motor 105 drives the moving plate 4 to move, so that the other end of the steel pipe is connected with the second mounting block 403 on the moving plate 4, and the four second electric push rods 404 are opened to drive the four second extrusion plates 405 to move respectively, so as to fix the other end of the steel pipe, and then the steel pipe can be drilled. During the drilling process, the first motor 313 can drive the guide plate 314 to rotate, thereby driving the first inner support plate 309 and the second inner support plate 319 to move, and then the first inner support plate 309 and the second inner support plate 319 support the inner wall of the steel pipe. At the same time, the fifth motor 606 can drive the drill bit 603 to move along the length direction of the steel pipe, and the fourth cylinder 601 can drive the drill bit 603 to move up and down, and the fourth motor 602 can drive the drill bit 603 to rotate, so as to realize drilling of the steel pipe, wherein the support of the first inner support plate 309 prevents the drill bit 603 from collapsing and deforming when drilling the hole. In this case, the debris generated during the hole opening will fall into the material storage barrel 303 through the material receiving hole 310, the sliding pipe 308 and the first sleeve 307. At this time, the third cylinder 503 is opened, and the dust suction pipe 502 will move under the drive of the third cylinder 503. When the docking joint 504 at one end of the dust suction pipe 502 is docked with the material storage barrel 303, the vacuum cleaner 501 can be opened to suck out the debris in the material storage barrel 303. When it is necessary to open holes at different positions of the steel pipe, the first cylinder 301 is opened at this time, thereby driving the first inner support plate 309 to move along the length direction of the steel pipe. The plate 309 can support the inner wall of the steel pipe along the length direction of the steel pipe, so that the drill bit 603 can make a hole in the steel pipe along the length direction. In addition, the second motor 207 can drive the first turntable 202 to rotate, thereby driving the steel pipe to rotate. When the steel pipe rotates, the first motor 313 drives the first inner support plate 309 to move downward, so that the first inner support plate 309 does not affect the rotation of the steel pipe and is always in an upward state. When the steel pipe rotates well, the first motor 313 drives the first inner support plate 309 again to support the inner wall of the steel pipe, so that the drill bit 603 can make a hole in the circumference of the steel pipe.
