Description

Technical Field

[0001] This invention belongs to the field of drilling equipment technology, and specifically relates to an automatic pipe punching device. Background Technology

[0002] Traditional pipe punching processes typically involve multiple workers collaborating to complete a series of actions, including loading, punching, and unloading the pipes. This method is not only inefficient and costly in terms of labor, but it also fails to guarantee the quality of the punching.

[0003] To address the aforementioned issues, Chinese utility model patent CN211889106U discloses an automatic drilling device for pipes. This device uses a fourth hydraulic rod to retract, causing a lifting slide to move downwards within a support seat until the top of the lifting slide is below the bottom of the pipe stack seat. The fourth hydraulic rod then extends, causing the pipe to rise while simultaneously blocking other pipes on the stack seat. When the lifting slide is higher than the side seat, the pipe rolls down the inclined surfaces of the lifting slide and the side seat onto the limiting pipe seat, achieving automatic feeding. A first hydraulic rod extends, causing a first pusher to push the pipe, while a second hydraulic rod extends, causing a second pusher to move until the pipe is limited between the first and second pushers. The pipe then moves to the drilling point for drilling. After drilling, the second hydraulic rod extends, and the first hydraulic rod extends and retracts until it reaches above the outlet groove. The first hydraulic rod then continues to retract, and the pipe passes through the outlet groove and discharge groove to complete the unloading process.

[0004] However, in actual use, it was found that the device still has shortcomings:

[0005] 1) This device can only punch holes at a single angle along the axial direction of the pipe, and cannot meet the needs of multi-angle punching.

[0006] 2) The pipe is clamped by squeezing from both ends to the middle. If the clamping force is too small, the pipe is prone to vibration; if the force is too large, it is easy to damage the pipe. Therefore, there is a problem of low clamping reliability.

[0007] 3) The material feeding process is complicated, requiring the cooperation of two hydraulic devices to complete the material feeding action, which increases the additional cost of the equipment and reduces the efficiency of punching.

[0008] Therefore, it is necessary to design a punching device that can stably clamp the pipe to ensure the punching requirements, and can automatically load and unload the pipe to improve punching efficiency. Summary of the Invention

[0009] In order to overcome the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a punching device that can both stably clamp the pipe to ensure the punching requirements of the pipe and automatically load and unload the material to improve the punching efficiency.

[0010] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: an automatic pipe punching device, characterized in that it includes an automatic feeding mechanism, a multi-angle punching mechanism and an automatic unloading mechanism arranged in an assembly line; the multi-angle punching mechanism includes a clamping component; the automatic feeding mechanism includes a height adjustment frame, a pushing component, a discharging component and a dropping hopper arranged sequentially from bottom to top; the discharge end of the pushing component is directly opposite the clamping component.

[0011] The beneficial effects of the present invention are as follows: The automatic pipe punching device provided by the present invention has a compact structure and low cost. Through the cooperation between the automatic feeding mechanism, the multi-angle punching mechanism and the automatic unloading mechanism, the pipe can be automatically and orderly fed, punched and unloaded, which ensures punching efficiency and accuracy while saving production costs.

[0020] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] The most crucial concept of this invention lies in the fact that the automatic feeding mechanism, the multi-angle punching mechanism, and the automatic unloading mechanism work together to enable the pipe to be automatically and orderly fed, punched, and unloaded, thus ensuring punching efficiency and accuracy while saving production costs.

[0022] Please refer to Figures 1 to 4 The automatic pipe punching device provided by the present invention includes an automatic feeding mechanism 1, a multi-angle punching mechanism 2 and an automatic unloading mechanism 3 arranged in an assembly line; the multi-angle punching mechanism 2 includes a clamping component 21; the automatic feeding mechanism 1 includes a height adjustment frame 11, a pushing component 12, a discharging component 13 and a dropping hopper 14 arranged sequentially from bottom to top; the discharge end of the pushing component 12 is directly opposite the clamping component 21.

[0023] As can be seen from the above description, the beneficial effects of the present invention are as follows: It provides an automatic pipe punching device, which enables the pipe to be discharged in an orderly manner through the cooperation between the height adjustment frame 11, the pushing component 12, the discharging component 13 and the dropping hopper 14, thereby avoiding blockage during the pushing process; the clamping component 21 and the multi-angle punching mechanism 2 can punch through holes of the required angle on the pipe; finally, the pipe is pushed further to the automatic unloading mechanism 3 to complete the entire punching operation; the device is low in cost, compact in structure and easy to operate. Compared with existing punching devices, it can meet the needs of multi-angle punching of pipes, and the automated processing steps are more reasonable, thereby improving the overall processing accuracy and efficiency.

[0024] Furthermore, the feeding assembly 12 includes a V-shaped feeding slide rail 121 and a feeding cylinder 122; the discharge end of the V-shaped feeding slide rail 121 is positioned directly opposite the clamping assembly 21, and the feeding end of the V-shaped feeding slide rail 121 is connected to the feeding cylinder 122; the axis of the feeding cylinder 122 is parallel to the axis of the V-shaped feeding slide rail 121 and the movable end is positioned towards the clamping assembly 21.

[0025] Furthermore, a jog switch is provided at the connection between the pusher cylinder 122 and the V-shaped pusher slide rail 121; a light source sensor is provided on the movable end of the pusher cylinder 122.

[0026] Furthermore, the discharge assembly 13 includes a distributing roller 131, a discharge plate 132, a limiting plate 133, a first drive motor, and a second drive motor; the distributing roller 131 is connected to the first drive motor; the distributing roller 131 has distributing grooves 1311 distributed axially on its side; the discharge plate 132 is located below the discharge end of the distributing roller 131, and the discharge end of the discharge plate 132 is oriented towards the V-shaped pusher slide rail 121; the feed end of the discharge plate 132 is higher than the discharge end and the discharge end is hinged to the limiting plate 133; the limiting plate 133 is connected to the second drive motor; the first drive motor and the second drive motor are electrically connected to a jog switch.

[0027] Furthermore, the horizontal cross-section of the discharge hopper 14 is a rectangle with a gradually decreasing width from top to bottom; the small end of the discharge hopper 14 is the discharge end; the discharge end is set towards the distribution roller 131, and when the distribution trough 1311 is directly opposite the discharge end, the projection surface of the discharge end is completely located within the distribution trough 1311.

[0028] As described above, when the pusher cylinder 122 retracts and touches the jog switch, the second drive motor drives the limit plate 133 to rotate until it is parallel to the discharge plate 132. At this time, the pipe on the discharge plate 132 can roll to the V-shaped pusher slide rail 121 due to gravity. When the light source sensor on the moving end of the pusher cylinder 122 senses the pipe, the pusher cylinder 122 can drive the pipe to move towards the clamping assembly 21. At the same time, the second drive motor drives the limit plate 133 to rotate in the opposite direction to return the limit plate 133 to the initial position. The first drive motor drives the distribution roller 131 to rotate by a working angle, so that the subsequent pipe to be punched is discharged from the distribution groove 1311 and rolls along the discharge plate 132 to the limit plate 133 to wait for the subsequent punching command, thereby realizing the automatic feeding of the pipe.

[0029] Furthermore, the clamping assembly 21 includes a first positioning groove 211, a second positioning groove 212, and a first driving device 213; both the first positioning groove 211 and the second positioning groove 212 are provided with V-shaped slots 214; the first positioning groove 211 and the second positioning groove 212 are located in the same horizontal plane and the slots are arranged opposite to each other; the second positioning groove 212 is connected to the movable end of the first driving device 213.

[0030] As can be seen from the above description, this design enables the tube to be automatically clamped after it moves to the clamping assembly 21, which not only ensures the subsequent punching work but also improves the clamping efficiency.

[0031] Furthermore, the multi-angle punching mechanism 2 includes a base 22, and an angle plate 23, a cantilever 24, and a punching machine 25 disposed above it; the angle plate 23 is connected to the base 22; one end of the cantilever 24 is hinged to the angle plate 23, and the cantilever 24 is rotatable relative to the angle plate 23; the other end of the cantilever 24 is provided with a punching machine 25 slidably connected thereto; the punching end of the punching machine 25 is disposed towards the hinge point between the cantilever 24 and the angle plate 23.

[0032] As can be seen from the above description, this design, through the rotation between the cantilever 24 and the angle plate 23, and the movement between the punching machine 25 and the cantilever 24, enables the punching machine 25 to punch through holes in the pipe at angles that meet design requirements.

[0033] Furthermore, the automatic feeding mechanism 3 includes a first feeding frame 31 and a second feeding frame 32 symmetrically arranged on both sides of the pipe moving direction; each of the first feeding frame 31 and the second feeding frame 32 is provided with a support frame 33, and a feeding half-sleeve 34 and a second driving device 35 are provided on the support frame 33; the feeding half-sleeve 34 is slidably connected to the support frame 33; the fixed end of the second driving device 35 is connected to the support frame 33, and the movable end is connected to the feeding half-sleeve 34; the inner walls of the two feeding half-sleeves 34 form a cylinder; the height of the automatic feeding mechanism 3 is the same as the height of the clamping assembly 21.

[0034] Furthermore, the inner wall of the feeding half-sleeve 34 is provided with a feeding wheel 341; the axis of the feeding wheel 341 is perpendicular to the direction of pipe movement.

[0035] Furthermore, the axis of the cylinder formed by the inner walls of the two feeding half-sleeves 34 is parallel to the direction of movement of the pipe.

[0036] As can be seen from the above description, after punching is completed, the second drive device 35 drives the unloading half sleeve 34 to move towards the pipe until the unloading wheel 341 abuts against the pipe. The rotation of the unloading wheel 341 can drive the pipe out of the punching device, thus completing the entire punching operation.

[0037] The automatic pipe punching device of the present invention can be used for pipe punching.

[0050] Reference Figures 1 to 4 Embodiment seven of the present invention is as follows:

[0051] An automatic pipe punching device, based on Embodiment 1, includes an automatic feeding mechanism 3 comprising a first feeding frame 31 and a second feeding frame 32 symmetrically arranged on both sides of the pipe moving direction; each of the first feeding frame 31 and the second feeding frame 32 is provided with a support frame 33, and a feeding half-sleeve 34 and a second driving device 35 are provided on the support frame 33; the feeding half-sleeve 34 is slidably connected to the support frame 33; the fixed end of the second driving device 35 is connected to the support frame 33, and the movable end is connected to the feeding half-sleeve 34; the inner walls of the two feeding half-sleeves 34 form a cylinder; the height of the automatic feeding mechanism 3 is the same as the height of the clamping assembly 21; the inner wall of the feeding half-sleeve 34 is provided with a feeding wheel 341; the axis of the feeding wheel 341 is perpendicular to the pipe moving direction; the axis of the cylinder formed by the inner walls of the two feeding half-sleeves 34 is parallel to the pipe moving direction.

[0052] The working principle of this invention is as follows: Before punching, adjust the height between the automatic feeding mechanism 1, the multi-angle punching mechanism 2, and the automatic unloading mechanism 3 so that the V-shaped pusher slide rail 121, the clamping assembly 21, and the unloading half-sleeve 34 are at the same height; after adjusting the height, start the pusher cylinder 122 to move the tube along the direction of the V-shaped pusher slide rail 121 toward the clamping assembly 21 until the tube groove reaches the designated position. Then, the first drive device 213 drives the first positioning groove 211 and the second positioning groove 212 to move toward the tube until the first positioning groove 211 and the second positioning groove 212 completely clamp the tube. The tube is punched with a through hole at the angle required by the design through the combined motion of the angle plate 23, the cantilever 24 and the punching machine 25; then the first driving device 213 moves in the opposite direction to release the tube from the first positioning groove 211 and the second positioning groove 212, and the punched tube is further moved to the automatic unloading position by the pusher cylinder 122; when the tube reaches the designated position, the second driving device 35 drives the unloading half sleeve 34 to approach the tube until the unloading wheel 341 abuts against the tube, and the rotation of the unloading wheel 341 can move the tube out of the punching device.

[0053] At this time, the pusher cylinder 122 retracts. When the pusher cylinder 122 touches the jog switch, the second drive motor drives the limit plate 133 to rotate until it is parallel to the discharge plate 132. At this time, the pipe on the discharge plate 132 can roll to the V-shaped pusher slide rail 121 due to gravity. When the light source sensor on the moving end of the pusher cylinder 122 senses the pipe, the pusher cylinder 122 can drive the pipe to move towards the clamping assembly 21. At the same time, the second drive motor drives the limit plate 133 to rotate in the opposite direction so that the limit plate 133 returns to the initial position. The first drive motor on the discharge mechanism 13 drives the distribution roller 131 to rotate by a working angle. The perforated pipe that falls from the discharge end of the drop hopper 14 into the distribution groove 1311 is discharged from the distribution groove 1311 and rolls along the discharge plate 132 to the limit plate 133 to wait for the subsequent punching command. Then the pusher assembly 12 repeats the above steps to realize the automatic punching of the pipe.

[0054] In summary, the automatic pipe punching device provided by this invention has a compact overall structure, low cost, and convenient operation. The cooperation between the height adjustment frame, the pushing assembly, the discharging assembly, and the dropping hopper ensures orderly pipe discharge, thus preventing blockage during pushing. The cooperation between the clamping assembly and the multi-angle punching mechanism punches through holes of the required angle on the pipe. Finally, pushing the pipe further towards the automatic unloading mechanism completes the entire punching process. This invention overcomes the shortcomings of existing punching devices, which not only fail to meet the needs of multi-angle pipe punching but also suffer from unreasonable automated processing steps, thus failing to improve overall processing accuracy and efficiency.
