[0004] Existing punching devices require manual rotation of a handwheel to drive a threaded rod inside a threaded sleeve during the punching process. This causes the upper clamping plate to move away from or towards the lower clamping plate, thus loosening or clamping the pipe. The entire operation is cumbersome and not conducive to improving the punching efficiency of pipes. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an automated pipeline processing device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic pipe processing equipment, including a processing box, a punching mechanism provided on the processing box, two sets of fixed vertical plates symmetrically arranged about the middle of the processing box fixed on the top of the processing box, a fixed horizontal bar fixed between the two sets of fixed vertical plates, the punching mechanism including a clamping assembly, the clamping assembly including a U-shaped frame fixed to the top of the processing box and located between the two sets of fixed vertical plates, a lower clamping block fixed to the top of the horizontal section of the U-shaped frame, a fixed horizontal plate fixed to the fixed horizontal bar, a hydraulic push rod fixed to the fixed horizontal plate, and an upper clamping block fixed to the end of the push rod of the hydraulic push rod, the top of the lower clamping plate is provided with a lower clamping groove extending to both sides of the lower clamping plate, and the bottom of the upper clamping plate is provided with an upper clamping groove extending to both sides of the upper clamping plate at a position corresponding to the lower clamping groove, the punching mechanism also includes a punching component for punching pipes.

[0007] By adopting the above technical solution, during the pipe punching process, the pipe is first placed on the lower clamping groove. Then, the hydraulic push rod operates, extending its end to its maximum stroke. During this process, the fixed horizontal plate lowers the upper clamping plate until it is flush with the lower clamping plate. At this point, the upper and lower clamping grooves clamp and position the pipe. Finally, the punching assembly punches the pipe. After punching, the hydraulic push rod operates again, retracting its end to its minimum stroke. During this process, the fixed horizontal plate and upper clamping plate rise and reset, the upper and lower clamping grooves separate, and the pipe is released. The entire operation eliminates the cumbersome manual operation of rotating the handwheel to release or clamp the pipe, thus improving the pipe punching efficiency.

[0008] Furthermore, the punching assembly includes a cylinder fixed to the top wall of the processing box, the piston rod of the cylinder passing through the top of the processing box and slidingly engaged, the punching assembly also includes a mounting base fixed to the end of the piston rod of the cylinder and a punching head passing through the horizontal section of the U-shaped frame and slidingly engaged, the lower end of the punching head being fixed to the top of the mounting base, and the punching head passing through the bottom of the lower clamping groove and slidingly engaged.

[0009] By adopting the above technical solution, after the cylinder works, the cylinder's telescopic rod extends and retracts, causing the mounting base connected to the cylinder's telescopic rod and the punching head connected to the mounting base to rise and fall. During this process, the punching head first rises and passes through the side wall of the pipe, and finally the punching head descends and moves away from the pipe and resets, thus realizing the punching work on the pipe.

[0010] Furthermore, the processing box is provided with a hole-expanding mechanism, which includes a hole-expanding slide mounted on the top of the processing box, a mounting slide mounted on the top of the hole-expanding slide, a hole-expanding screw mounted rotatably on the mounting slide, a hole-expanding slider mounted on the mounting slide and threadedly connected to the hole-expanding screw, a hole-expanding motor fixed on the mounting slide and driving the hole-expanding screw to rotate, and a hole-expanding punch fixed to the hole-expanding slider.

[0011] By adopting the above technical solution, after the hole-expanding motor works, it drives the hole-expanding screw to rotate, causing the hole-expanding slider connected to the hole-expanding screw and the hole-expanding punch connected to the hole-expanding slider to move toward or away from the pipe. In this process, the hole-expanding punch first inserts into the inside of the pipe and expands the hole in the pipe, and finally the hole-expanding punch moves away from the inside of the pipe and resets, thus achieving the purpose of expanding the hole in the pipe and expanding the applicable range of the device.

[0012] Furthermore, the enlarging slide is provided with a displacement assembly, which includes a fixed slide fixed to the top of the enlarging slide, a displacement screw rotatably mounted on the fixed slide, a displacement slider slidably mounted on the fixed slide and threadedly connected to the displacement screw, a displacement motor fixed on the fixed slide and driving the displacement screw to rotate, and a connecting block for connecting the fixed slide and the mounting slide, wherein the mounting slide is slidably mounted on the top of the enlarging slide.

[0013] By adopting the above technical solution, after the displacement motor works, it drives the displacement screw to rotate, so that the displacement slider, which is threadedly connected to the displacement screw and slidingly engaged with the fixed slide, the connecting block connected to the movable slider, and the mounting slide connected to the connecting block move toward or away from the pipe. The distance between the mounting slide and the U-shaped frame can be adjusted to accommodate the expansion of pipes of various lengths, thereby improving the expansion range of the expansion mechanism.

[0014] Furthermore, the enlarging slide is provided with a grooving assembly, which includes a grooving slider slidably disposed on the top of the enlarging slide, a grooving sleeve fixed on the grooving slider, a plurality of grooving cutters fixed to the inner wall of the grooving sleeve and evenly distributed about the axis of the grooving sleeve, and a grooving electric push rod fixed on the mounting slide. The push rod end of the grooving electric push rod is fixed to the grooving slider. The inner diameter of the grooving sleeve is equal to the outer diameter of the pipe. The processing box is provided with a moving component for adjusting the position of the mounting slide.

[0015] By adopting the above technical solution, the operator drives the moving component to adjust the position of the mounting slide on the processing box and aligns the grooving sleeve with the pipe. At this time, the electric grooving push rod works and extends and retracts its end, causing the grooving slider to drive the grooving sleeve and grooving knife to move towards or away from the pipe. In this process, the grooving tube first approaches and covers the pipe, while the grooving knife cuts the end of the pipe. Finally, the grooving knife and grooving sleeve move away from the pipe and reset, thus achieving the purpose of grooving the pipe and expanding the overall application range of the device.

[0016] Furthermore, the moving component includes a fixed plate fixed to the bottom of the reaming slide, a moving screw threaded through the fixed plate, a moving motor fixed to the top of the processing box and driving the moving screw to rotate, and a moving slide rail fixed to the top of the processing box and slidingly engaged with the reaming slide.

[0017] By adopting the above technical solution, after the moving motor works, it drives the moving screw to rotate, so that the fixed plate threadedly connected to the moving screw and the hole-expanding slide connected to the fixed plate both move, thereby changing the position of the hole-expanding mechanism and the grooving assembly, so as to perform grooving or hole-expanding work on the pipeline.

[0018] Furthermore, the processing box is equipped with a hole-reducing mechanism. The hole-reducing mechanism and the hole-expanding mechanism are symmetrically arranged about the middle of the horizontal section of the U-shaped frame. The hole-reducing mechanism includes a hole-reducing assembly, which includes a movable slide block slidably disposed on the top of the processing box, a hole-reducing slide block slidably mounted on the top of the movable slide block, a hole-reducing electric push rod fixed to the top of the movable slide block, a lifting slider disposed on the hole-reducing slide block, and a shrinking sleeve fixed to the lifting slider. The shrinking sleeve has a transition hole communicating with the inside of the shrinking sleeve at one end near the U-shaped frame. The axis of the transition hole coincides with the axis of the shrinking sleeve. The distance between the inner wall of the transition hole and the axis of the shrinking sleeve gradually increases from the shrinking sleeve to the U-shaped frame. The push rod end of the hole-reducing electric push rod is fixed to the hole-reducing slide block.

[0019] By adopting the above technical solution, after the orifice reduction electric push rod is working, its push rod end extends and retracts, causing the orifice reduction slide connected to the push rod end, the lifting slider connected to the orifice reduction slide, and the tube reduction sleeve connected to the lifting slider to move towards or away from the pipeline. In this process, firstly, the tube reduction sleeve approaches and covers the outer wall of the pipeline, the tube reduction sleeve squeezes the pipeline, and finally the tube reduction sleeve moves away from the pipeline and resets, thus achieving the purpose of reducing the orifice of the pipeline and expanding the application range of the device.

[0020] Furthermore, multiple shrinking sleeves are provided and vertically distributed, with the inner diameter of the multiple shrinking sleeves gradually increasing from top to bottom. The lifting slider is slidably installed on the shrinking hole slide block, and the shrinking hole slide block is provided with a lifting assembly. The lifting assembly includes a lifting screw that passes through the top of the lifting slide block and is threadedly connected, and a lifting motor that is fixed on the shrinking hole slide block and drives the lifting screw to rotate.

[0021] By adopting the above technical solution, after the lifting motor works, it drives the lifting screw to rotate, causing the lifting slider threadedly connected to the lifting screw and the multiple shrinking sleeves connected to the lifting slider to rise and fall. Since the inner diameter of the multiple shrinking sleeves gradually increases from top to bottom, the multiple shrinking sleeves can be adjusted one by one from bottom to top to the height corresponding to the pipe and the pipe can be reduced in diameter, thereby achieving the purpose of reducing the diameter of the pipe. This multi-step forming operation can reduce the amount of diameter reduction in the pipe compared to the one-time forming operation, and reduce the probability of pipe deformation caused by a large amount of diameter reduction.

[0022] Furthermore, the upper clamping slot is provided in multiple ways, and the number of the lower clamping slots, the number of punching heads, and the number of upper clamping slots are equal and their positions correspond one-to-one. The processing box is provided with a position adjustment assembly, which includes an adjustment slide rail fixed to the top of the processing box and slidingly engaged with the movable slide, a connecting plate fixed to the bottom of the movable slide, an adjustment screw threaded through the connecting plate and connected by threads, and an adjustment motor fixed to the top of the processing box and driving the adjustment screw to rotate.

[0023] By adopting the above technical solution, after the adjusting motor works, it drives the adjusting screw to rotate, which causes the connecting plate threaded to the adjusting screw and the movable slide fixed to the connecting plate to move, thereby changing the position of the hole-reducing mechanism in the processing box. This allows the pipes at multiple punching head positions to be processed, improving the hole-reducing efficiency of the pipes.

[0024] Furthermore, a limiting vertical rod is fixed to the top of the processing box, the limiting vertical rod passes through the bottom of the mounting base and is slidably engaged, and the limiting vertical rod passes through the bottom of the upper clamping block and is slidably engaged.

[0025] By adopting the above technical solution, the setting of the limiting vertical rod improves the stability of the mounting base and the upper clamping block during movement.

[0026] In summary, the present invention has the following beneficial effects: In this application, by setting up the clamping component, the tedious operation of manually rotating the handwheel to loosen or clamp the pipe is eliminated, thereby improving the pipe punching efficiency.

During this process, the fixed horizontal plate 213 drives the upper clamping plate to descend until the upper clamping plate is close to the lower clamping plate. At this time, the upper clamping groove 6 and the lower clamping groove 5 tighten and position the pipe. Then, the cylinder 221 is activated and its telescopic rod extends and retracts, causing the mounting base 222 connected to the telescopic rod of the cylinder 221 and the punching head 223 connected to the mounting base 222 to rise and fall. During this process, the punching head 223 first rises and passes through the side wall of the pipe, and finally the punching head 223 descends away from the pipe and resets, thus realizing the pipe punching work.

The operator drives the movable component 10 to adjust the position of the mounting slide 72 on the processing box 1 and aligns the grooving sleeve with the pipe. At this time, the grooving electric push rod 93 works and extends and retracts its end, causing the grooving slider 91 to drive the grooving sleeve 92 and the grooving knife to move towards or away from the pipe. In this process, the grooving tube first approaches and covers the pipe, while the grooving knife cuts the end of the pipe.

The movable slide rail 104 is fixed to the top of the processing box 1 and slides in cooperation with the reaming slide 71.

Multiple shrinking sleeves 115 are fixed to the lifting slider 114 and are vertically distributed. The inner diameter of multiple shrinking sleeves 115 gradually increases from top to bottom, and a transition hole communicating with the inside of the shrinking sleeve 115 is opened at the end of the shrinking sleeve 115 near the U-shaped frame 211. The axis of the transition hole coincides with the axis of the shrinking sleeve 115, and the distance between the inner wall of the transition hole and the axis of the shrinking sleeve 115 gradually increases from the shrinking sleeve 115 to the U-shaped frame 211. After the shrinking electric push rod 113 is operated, its push rod end extends and retracts, causing the shrinking slide 112 connected to the push rod end, the lifting slider 114 connected to the shrinking slide 112, and the shrinking sleeve 115 connected to the lifting slider 114 to move towards or away from the pipeline. In this process, firstly, the shrinking sleeve 115 approaches and fits around the outer wall of the pipeline, the shrinking sleeve 115 squeezes the pipeline, and finally the shrinking sleeve 115 moves away from the pipeline and returns to its original position, thus achieving the purpose of shrinking the pipeline and expanding the application range of the device.

The lifting screw 121 is threaded through and disposed on the top of the lifting slide 112. The lifting motor 122 is fixed on the orifice reduction slide 112 and drives the lifting screw 121 to rotate. After the lifting motor 122 works, it drives the lifting screw 121 to rotate, so that the lifting slider 114 threadedly connected to the lifting screw 121 and the multiple tube reduction sleeves 115 connected to the lifting slider 114 are raised and lowered. Since the inner diameter of the multiple tube reduction sleeves 115 gradually increases from top to bottom, the multiple tube reduction sleeves 115 can be adjusted one by one from bottom to top to the height corresponding to the pipe and the orifice reduction operation is performed on the pipe, thereby achieving the purpose of orifice reduction of the pipe. This multi-step forming operation can reduce the amount of orifice reduction of the pipe compared with the one-time forming operation, and reduce the probability of pipe deformation caused by a large amount of orifice reduction.

The adjustment motor 134 is fixed to the top of the processing box 1 and drives the adjustment screw 133 to rotate. After the adjustment motor 134 operates, it drives the adjustment screw 133 to rotate, causing the connecting plate 132 threadedly connected to the adjustment screw 133 and the movable slide block 111 fixed to the connecting plate 132 to move. This changes the position of the hole-reducing mechanism 11 in the processing box 1, allowing processing of pipes at multiple punch head 223 positions and improving the hole-reducing efficiency of the pipes.
