[0002] A pipe cutting device is a mechanical device specifically used to accurately cut pipes to the required length. This device usually includes a fixing device, a cutting knife, a drive system, and a control system to ensure that the pipe can be cut into the appropriate size quickly and accurately.

[0003] Existing pipe cutting devices cut pipes by driving a cutting knife to move downward. However, the cutting knife will inevitably wear out after long-term use. In order not to affect the cutting quality of the pipe, personnel need to use external tools to remove the cutting knife from the driving mechanism by disassembling multiple bolts in sequence, and then tighten several bolts to install a new cutting knife for replacement. The process of removing and installing the cutting knife is time-consuming, affecting production efficiency and increasing the labor intensity of the operator. Utility Model Content

[0004] In view of this, the utility model addresses the deficiencies of the existing technology and provides a pipe cutting device that can quickly disassemble and replace the cutting knife by simply pushing the push plate without the aid of external tools, significantly shortening the replacement time, improving production efficiency, and reducing the labor intensity of the operator.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows: a pipe cutting device, comprising a cutting table, a connecting plate is provided on the right side of the upper end of the cutting table, a sliding frame is provided inside the connecting plate through a sliding column, a cutting knife is slidably provided inside the sliding frame, a notch for cooperating with the cutting knife is provided on the right side of the interior of the cutting table, a quick-disassembly mechanism for quickly disassembling the cutting knife is provided on the front and rear sides of the sliding frame, an adjustable pipe conveying limit mechanism is provided on the left side of the upper end of the cutting table, the quick-disassembly mechanism comprises frame plates provided on the front and rear sides of the sliding frame, locking columns are slidably provided inside the two frame plates, and the front of the two locking columns Corresponding to the rear position, locking columns are respectively provided on the front and rear sides of the cutting knife, and the two locking columns pass through the through holes provided in the sliding frame and are plugged into adjacent locking holes. A rotating seat is provided on the outer ends of the two locking columns, and a connecting frame is rotatably provided inside the two rotating seats. A rotating frame is rotatably provided between the right sides of the two connecting frames, and an elastic driving unit is provided between the rotating seat and the frame plate. The elastic driving unit includes a plurality of springs arranged between the rotating seat and the frame plate. The two springs are respectively arranged on the outer arc surfaces of the corresponding locking columns. A push plate is provided on the right side of the rotating frame, and an anti-slip pad is provided on the right side of the push plate. The push plate and the protective pad are bonded.

[0006] As a further improvement of the present invention, the conveying limiting mechanism includes two rectangular plates arranged on the left side of the cutting table, and the front and rear positions of the two rectangular plates correspond to each other. Two electric push rods are provided on the inner side surfaces of the two rectangular plates, and frames are provided on the telescopic ends of the two electric push rods. Multiple rollers are rotatably arranged inside the two frames, and multiple rotating rollers are rotatably arranged inside the cutting table.

[0007] As a further improvement of the present invention, a control panel is provided on the front side of the cutting table, and the first electric push rod and the second electric push rod are both electrically connected to the control panel.

[0008] As a further improvement of the present invention, a support frame is provided at the lower end of the cutting table, and the cutting table and the support frame are fixed by welding.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] First, the pipe to be cut is transported to the rotating roller by controlling the external pipe feeding mechanism, and then the electric push rod is controlled to operate. The telescopic end drives the rollers inside the two side frames to approach each other to achieve the limitation of the front and rear sides of the pipe. Then, the external feeding mechanism is controlled to cooperate with the rotation of the rotating roller and the limitation of the roller, so that the pipe is transported to the lower end of the cutting knife. After reaching the appropriate cutting length, the electric push rod is controlled to operate, which drives the cutting knife inside the sliding frame to move downward to cooperate with the notch to quickly achieve limited cutting of the pipe.

[0011] Secondly, by pushing the push plate to the left, the internal rotation and expansion of the rotating frame are driven, and the locking posts on the rotating seats on both sides are moved away from the locking holes inside the cutting knife. At this time, the spring is in a stretched state, and the worn cutting knife can be slid out of the interior of the sliding frame, and the new cutting knife can be slid into the interior of the sliding frame. Then the pull plate is released, and the spring rebounds quickly, so that the locking posts on both sides are inserted into the interior of the locking holes on the new cutting knife, so that the cutting knife can be quickly replaced. The cutting knife can be quickly disassembled and replaced by pushing the push plate without the aid of external tools, which can significantly shorten the replacement time, improve production efficiency, and reduce the labor intensity of the operator.

[0012] Thirdly, the anti-slip pad can prevent people from slipping when pushing the push plate, making it smoother for people to replace the cutting knife and making it easier for people to replace.

[0013] Fourthly, the support frame at the lower end can provide stable support to the cutting device, thereby improving the stability of pipe cutting and indirectly improving the cutting quality of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS
