Description

Technical Field

[0001] The utility model relates to a punching device, in particular to a punching device for pipe production. Background Art

[0002] Pipes refer to various materials used to manufacture pipelines, which are widely used in multiple industries such as construction, industry, agriculture, water treatment, and natural gas and oil transportation. Pipes are usually cylindrical and hollow to allow liquids or gases to pass through. They can be made of a variety of materials, depending on the needs of the application, such as pressure resistance, corrosion resistance, cost and working environment. Pipe punching is usually an operation performed during the processing and manufacturing of metal or plastic pipes. Its main purpose is to divide the continuous pipe into sections of specific lengths for subsequent use or further processing. Punching can be applied to many types of pipes, including but not limited to stainless steel pipes, copper pipes, aluminum pipes, PVC pipes, PE pipes, etc.

A conveyor belt 10 is provided between the baffles 9 on both sides, and a second connecting member 11 is fixedly connected between the left and right sides of the outer frame 3 and the outer sides of the baffles 9 on both sides.

[0021] like Figure 1 、 Figure 4-Figure 5 As shown, the feeding mechanism 2 includes a feeding table 20, a first fixed ring 21, a support frame 22, a servo motor 23, a first roller 24, a second roller 25, a dual-axis motor 26, a fixed plate 27 and a transmission belt 28. The feeding table 20 is fixedly installed on the front top of the bottom plate 1. The first fixed ring 21 is fixedly connected to the middle position of the front top of the feeding table 20. The left side of the feeding table 20 is connected to the support frame 22 by screws. The right end of the support frame 22 is fixedly installed with a servo motor 23, and the servo motor 23 is connected to the output shaft of the servo motor 23. There is a first roller 24, which is located in the middle position above the feeding platform 20. A second roller 25 is embedded in the middle of the top of the feeding platform 20. A dual-axis motor 26 is fixedly installed on the left side of the bottom of the feeding platform 20. The right output shaft of the dual-axis motor 26 is rotatably connected to the second roller 25. The first roller 24 and the second roller 25 are parallel to each other. A fixed plate 27 is fixedly connected to the right output shaft of the dual-axis motor 26, and a transmission belt 28 is rotatably sleeved on the right output shaft of the dual-axis motor 26 and the roller on the right side of the conveyor belt 10.

[0022] like Figure 1 and Figure 2As shown, the limiting mechanism 8 includes a first support member 80, a bevel gear 81, a rocker 82, a screw 83, a first connecting member 84, a limiting plate 85, a guide rod 86, a fixing member 87 and a second supporting member 14. The first supporting member 80 is fixedly connected to the left side of the middle part of the feeding platform 20. The rear side of the first supporting member 80 is rotatably connected to the bevel gear 81, and the rear side of the bevel gear 81 is rotatably connected to the screw 83. There are two first connecting members 84, one of which is threadedly connected to the rear part of the screw 83. The right side of the upper part of the first connecting member 84 is connected to the limiting plate 85, and the right side of the limiting plate 85 is connected to the second first connecting member 84. The inner bottom of the second first connecting member 84 is slidably connected to the guide rod 86, and The right side of the guide rod 86 is connected to the baffle 9 on the right side, and the left and right sides of the bottom of the outer frame 3 are fixedly connected with fixing parts 87. The left fixing part 87 is threadedly connected to the front of the screw 83, and the right fixing part 87 is fixedly connected to the front of the guide rod 86. The second support member 14 is fixedly connected to the middle position of the top left side of the base plate 1. The rotating sleeve on the second support member 14 is connected to another bevel gear 81. The two adjacent bevel gears 81 are meshed at 90°, and the bevel gear 81 on the second support member 14 is rotatably connected to the rocker 82 on the left side. Holding the rocker 82 and rotating it can drive the bevel gear 81 at its right end to rotate, so that it can mesh and rotate with the other bevel gear 81 and drive the screw 83 to rotate.

[0023] like Figure 2 As shown, a ruler 12 is also included. The ruler 12 is fixedly installed on the upper part of the left baffle 9. The ruler 12 is a length measuring piece for the auxiliary punching pipe.

[0024] like Figure 2 As shown, a pointer 13 is also included. The pointer 13 is connected to the lower middle portion of the left side of the first connecting member 84 by means of screws. The pointer 13 is used to indicate the measuring distance of the ruler 12.

[0025] When the operator uses the device to punch the pipe, one end of the pipe should first be inserted into the first fixed ring 21 on the feeding table 20, and the other end should be passed through the second fixed ring 7 on the workbench 6 to ensure that the position of the pipe is initially fixed. Then, the operator rotates the rocker 82 to drive the bevel gear 81 fixed to the rocker 82 to rotate, and then drives another bevel gear 81 engaged with it to rotate, thereby driving the screw 83 to rotate. The rotation of the screw 83 causes the first connecting member 84 sliding on it to move, and then drives the limit plate 85 to slide along the guide rod 86. At this time, the operator can judge whether the limit plate 85 has reached the required punching length by observing the position of the pointer 13 on the ruler 12. Once the predetermined length is reached, the operator stops the rotation of the rocker 82, and the position of the limit plate 85 is fixed. Then, the operator starts the servo motor 23 and the dual-axis motor 26. At this time, the output shaft of the servo motor 23 drives the first roller 24 to rotate, and the output shaft of the dual-axis motor 26 simultaneously drives the second roller 25 and the transmission belt 28 to rotate. The transmission belt 28 also drives the conveyor belt 10 to run. At this time, the pipe is pushed forward by the rotation of the first roller 24 and the second roller 25 until the pipe contacts the limit plate 85. At this time, the servo motor 23 is turned off. At this time, the operator turns off the servo motor 23, stops the first roller 24 from rotating to prevent the pipe from moving forward. Then, the operator starts the cylinder 4. At this time, the piston rod of the cylinder 4 drives the punch 5 to move downward to break the pipe. The broken pipe section will fall onto the running conveyor belt 10, and the conveyor belt 10 will transport it to the collection area. The operator can continue to collect the broken pipes in this process. After the breaking is completed, the operator needs to turn off the cylinder 4 and the dual-axis motor 26, reset the punch 5 and stop the operation of the conveyor belt 10, prepare for the next round of breaking processing, and repeat the above steps.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
