FIG. 1 is a schematic structural diagram of a non-sizing pipe cutting device according to an embodiment of the present application; fig. 2 is a schematic top view of a non-fixed-length pipe cutting device according to an embodiment of the present disclosure. Referring to fig. 1 and 2, an embodiment of the present application provides a non-sizing pipe cutting device, including:

the cutting machine 10 is used for cutting the pipe 50 to be cut;

the conveying mechanism 20 is used for conveying the pipe 50 to be cut, wherein one end of the pipe facing the advancing direction is a head end, and the other end of the pipe is a tail end;

the fixed-length mechanism 30 is used for determining the cutting length of the pipe, the fixed-length mechanism comprises a fixed-length stop block 31 which can move along the traveling route of the pipe to be cut conveyed by the conveying mechanism 20, and the distance between the fixed-length stop block 31 and the cutting point of the cutting machine 10 is the cutting length of the pipe;

the measuring mechanism 40 is used for measuring the length of the pipe to be cut 50, the measuring mechanism 40 and the sizing mechanism 30 are respectively positioned on two sides of the cutting machine 10, the measuring mechanism 40 can move along the advancing route of the pipe to be cut 50 conveyed by the conveying mechanism 20, and when the head end of the pipe to be cut 50 is positioned on the sizing stop block 31, the measuring mechanism 40 detects the position of the tail end of the pipe to be cut.

In the non-scale pipe cutting device measuring device provided by the embodiment of the application, the scale mechanism can determine the distance between the head end of the pipe to be cut and the cutting point of the cutting machine, so that scale cutting can be performed according to the distance. The measuring mechanism can detect the position of the tail end of the pipe material 50 to be cut when the head end of the pipe material 50 to be cut is positioned at the fixed length stop block 31. At this time, the distance from the fixed-length stop 31 to the cutting point of the cutting machine 10 is the current fixed-length cutting size. Therefore, the position from the cutting machine 10 to the tail end of the pipe to be cut 50, namely the length of the residual pipe to be cut 50 can be obtained, the reasonable cutting size or the cutting size combination can be determined according to the length of the pipe to be cut, and the raw material loss is reduced.

In the embodiment of the present application, the measuring mechanism 40 can move along the traveling path of the conveying mechanism 20 for conveying the pipe to be cut 50, so as to measure the pipe to be cut with different lengths. Likewise, the sizing mechanism 30 can also be moved along the path of travel of the conveyor 20 to convey the pipe 50 to be cut to determine different cut sizes.

In some embodiments, the distance that the sizing mechanism 30 can move can be determined based on the possible gauge length of the tubing to enable different length sized cuts. The distance that the measuring means 40 can be moved can be determined according to different needs. In an exemplary embodiment, the maximum distance of the measuring mechanism 40 to the cutting point of the cutting machine 10 is greater than the maximum distance of the cut-to-length stop 31 of the cut-to-length mechanism 30 to the cutting point of the cutting machine 10. By setting the maximum distance from the measuring mechanism 40 to the cutting point of the cutting machine 10 to be greater than the maximum distance from the fixed-length stop block 31 of the fixed-length mechanism 30 to the cutting point of the cutting machine 10, the remaining pipe to be cut can have enough length to carry out the optimal cutting scheme, and the consumption of raw materials is reduced to the maximum extent. The length of the residual pipe to be cut measured by the measuring mechanism 40 can be larger than the maximum fixed-length cutting size, the size matched with the residual length can be selected for cutting, the raw material loss can be reduced, and the residual cutting size is easy to determine.

In the embodiment of the present application, referring to fig. 5, the movement of the sizing mechanism 30 and the measuring mechanism 40 can be controlled in various ways. In the exemplary embodiment, the cut-off device further comprises a control unit 60. The control unit 60 may be used to control the operation of the entire shut-off device. For example, the control unit 60 may acquire different data. For example, the control unit 60 may determine a shut-down scheme based on the acquired data. The cutting scheme comprises the cutting length, the cutting number and the like of the pipe to be cut. For example, the control unit 60 may control the respective partial actions according to a shut-off scheme. The control unit 60 can realize high automation of the cutting device, reduce the number of operators, improve the measurement and sizing precision, and improve the cutting efficiency and cutting precision.

In some embodiments, the control unit 60 is connected to the sizing mechanism, and the control unit 60 is used for controlling the movement of the sizing block 31 of the sizing mechanism 30. The control unit 60 can send an instruction to the sizing mechanism 30 according to the cutting length, and control the sizing block 31 to move to the instruction position, so that the distance between the sizing block 31 and the cutting point of the cutting machine 10 is the cutting length, and the cutting machine 10 cuts the pipe to be cut according to the cutting length. The sizing block 31 can be quickly and accurately moved to a desired position by the control unit 60.

In some embodiments, a control unit 60 is coupled to the measurement mechanism 40, and the control unit 60 is configured to control the movement of the measurement mechanism 40. When the pipe to be cut is measured, the control unit 60 can control the measuring mechanism 40 to move to the tail end of the pipe to be cut 50, and the control unit 60 can obtain the position of the tail end of the pipe to be cut 50 when the head end of the pipe to be cut 50 abuts against the positioning stop block 31. The sizing block 31 can be quickly and accurately moved to the position corresponding to the tail end of the pipe 50 to be cut by the control unit 60.

In some embodiments, the control unit 60 can receive the position information of the tail end of the pipe 50 to be cut when the head end of the pipe 50 to be cut is abutted against the positioning stop 31, which is detected by the measuring mechanism 40. The control unit 60 determines the distance from the tail end of the pipe 50 to be cut to the cutting point of the cutting machine 10 according to the position information of the tail end of the pipe 50 to be cut. The control unit 60 can receive the position information of the tail end of the pipe 50 to be cut when the head end of the pipe 50 to be cut detected by the measuring mechanism 40 is abutted against the positioning stopper 31. And, the control unit 60 can obtain the remaining length of the pipe 50 to be cut according to the position information.

In some embodiments, a control unit 60 is connected to the cutting machine 10, and the control unit 60 is used for controlling the cutting machine 10 to cut the pipe 50 to be cut when the head end of the pipe 50 to be cut abuts against the sizing block 31. When the head end of the pipe 50 to be cut abuts against the sizing stop 31, the control unit 60 can send an instruction to the cutting machine, and the cutting machine 10 executes the instruction to cut off the pipe 50 to be cut. Controlling cutter 10 by control unit 60 may improve cutting efficiency and reduce equipment operators.

In some embodiments, the feeding mechanism 20 is connected to the control unit 60, and the control unit 60 controls the feeding mechanism 20 to feed the tube 50 to be cut. The automation of the cutting device can be improved by controlling the transport mechanism 20 by the control unit 60. When the head end of the pipe to be cut abuts against the fixed-length stop block 31, the control unit 60 sends a stop instruction, the conveying mechanism 20 executes the stop instruction to stop conveying, and the cutting machine 10 waits for cutting off the pipe to be cut 50. Then, the control unit 60 sends a conveying instruction, and the conveying mechanism 20 executes the conveying instruction, continues to convey the pipe 50 to be cut, and performs the next conveying-cutting process.

In some embodiments, referring to fig. 1, 2 and 4, the sizing mechanism 30 further includes a sizing slide 32, a sizing slide 33 and a sizing servo motor 34. Wherein, the fixed-length slide rail 32 and the advancing route of the conveying mechanism 20 for conveying the pipe 50 to be cut are arranged in parallel. The sizing slide 33 can slide along the sizing slide rail 32. The fixed length stop block 31 is arranged on the fixed length slide block 33. The sizing servomotor 34 is used to drive the sizing slider 33, thereby determining the cut length. The sizing servo motor 34 may be controlled by a control unit 60. The scaling servo motor 34 is connected to the control unit 60, and the control unit 60 controls the scaling servo motor 34 to drive the scaling slide 33 to the commanded position. The control unit 60 can send instructions to the sizing servomotor 34 according to the determined cut-off length, and the sizing servomotor 34 drives the sizing slide 33 to the corresponding position according to the instructions. At this time, the distance from the fixed length slider 33 to the cutting point of the cutter 10 is the cutting length. The control unit 60 can realize high automation of the cutting device, reduce the number of operators, and achieve higher sizing precision and higher sizing speed. The cutting efficiency and cutting accuracy can be improved.

In some embodiments, the sizing mechanism 30 further comprises a sizing block lifting mechanism for driving the sizing block 31 to lift relative to the sizing block 33. For example, the sizing block 31 and the sizing block 33 may be slidably connected, and the lifting motor drives the chain or the belt to reciprocate, and the sizing block 31 is connected to the belt or the chain, so as to move up and down under the driving of the belt or the chain. Of course, the sizing-stop lifting mechanism may be any mechanism or device that can determine the lifting of the sizing stop 31 with respect to the sizing slide 33, such as a robot arm, a telescopic cylinder, or an electric push rod. The position 31' in fig. 4 is the stopping position of the cut-to-length stop 31, so as to stop the pipe 50 to be cut. After the cutting is finished, the sizing stop lifting mechanism can drive the sizing stop 31 to ascend, so that the tube cut by sizing is conveyed continuously through the conveying mechanism 20. The sizing block lifting mechanism can be connected with the control unit 60, and the control unit 60 controls the sizing block lifting mechanism to drive the sizing block 31 to lift.

In some embodiments, referring to fig. 1, 2 and 3, the measuring mechanism 40 includes a measuring slide 41, a measuring slide 42, a position sensor 43 and a measuring servomotor 44. Wherein, the measuring slide rail 41 and the advancing route of the conveying mechanism 20 for conveying the pipe 50 to be cut are arranged in parallel. The measuring slide 42 can slide along the measuring slide. Position sensor 43 locates on measuring slider 42 for when waiting to cut tubular product head end and support in the scale dog, detect the position of waiting to cut the tubular product tail end. The measurement servo motor 44 is connected with the control unit 60, and the control unit 60 controls the measurement servo motor 44 to drive the measurement slide block 42 to move along the measurement slide rail 41, so as to detect the position of the tail end of the pipe 50 to be cut when the head end of the pipe 50 to be cut abuts against the fixed-length stop block 31. The control unit 60 can realize high automation of the cutting device, reduce the number of operators, and achieve higher measurement precision and higher measurement speed. The cutting efficiency and cutting accuracy can be improved.

In some embodiments, the measuring slide 42 may be set to a position as an initial position, and the position of the measuring slide 42 is also the position of the position sensor 43. In an exemplary embodiment, the initial position may be, for example, the position furthest from the cutting point of cutter 10. When the tail end of the pipe 50 to be cut passes through the initial position of the position sensor 43, the control unit 60 controls the measuring servo motor 44 to drive the measuring slide block 42 to move along the measuring slide rail 41, so as to detect the position of the tail end of the pipe 50 to be cut when the head end of the pipe 50 to be cut abuts against the fixed-length stop block 31.

In some embodiments, the conveyor is a roller or belt conveyor. Through which the pipe to be cut is conveyed on the cutting path.

In the embodiment of the present application, the control unit 60 employs a P L C (for example, a siemens S7-1200 model), a single chip microcomputer and an FPGA (Field Programmable Gate Array).

In the embodiment of the present application, the position sensor 43 is a proximity sensor (e.g., model number of kirschner EV-112U).

In the embodiment of the present application, the sizing servo motor 34 and the measuring servo motor 44 may be Siemens servo motors (for example, model number SIMOTICS S-1F L6).

The operation of the non-sizing pipe cutting device according to the embodiment of the present application will be described below by way of example.

The position sensor 43 of the measuring mechanism 40 is located farthest away from the cutting point of the cutter 10. The sizing block 31 of the sizing mechanism 30 is located at a position corresponding to the sizing length a, i.e., the distance from the cutting point of the cutting machine 10 to the sizing block 31 is equal to the sizing length a.

The conveying mechanism 20 conveys the pipe to be cut, and after the head end of the pipe collides with the fixed-length stop block, the pipe is cut off by the cutting machine, and the cut-off length is the fixed-length A.

The position sensor 43 of the tail end of the pipe to be cut passes through the measuring mechanism 40, and the head end of the pipe to be cut abuts against the fixed-length stop block 31, and then the measuring slide block 42 starts to move to detect the accurate position of the tail end of the pipe to be cut. At this time, the cutting device is still cut to the length A without changing the position.

After detecting the position of the tail end of the pipe to be cut, the control unit 60 obtains the dimension D from the tail end of the pipe to be cut to the cutting point of the cutting machine 10. The total length of the remaining uncut tubing at this point is D.

And calculating the length to be cut subsequently according to the total length D of the residual pipe to be cut. The most suitable combination of cutting schemes is selected. Two pipes of lengths B and C can also be cut, for example, according to the total length D of the remaining pipes to be cut.

The fixed-length stop block is moved to a proper length according to a cutting scheme, and fixed-length cutting of the residual pipes can be achieved. For example, the cutting length B is moved to a position corresponding to the cutting length B.

The above description is intended to be illustrative and not restrictive. For example, the above-described examples (or one or more versions thereof) may be used in combination with each other, and it is contemplated that the embodiments may be combined with each other in various combinations or permutations. The scope of the application should be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
