A steel pipe composite cutting device

Abstract

The present invention discloses a steel pipe composite cutting device, which relates to the technical field of steel pipe composite cutting, and includes a main body support and a side support rod. An input track support is arranged in the main body support, and a vertical guide rail and a longitudinal linear guide rail are arranged on the longitudinal beam at one end of the input track support. For this steel pipe composite cutting device, the material moves longitudinally along the roller path by a numerical control pinch roller and is positioned in the cutting area. The clamping device can move vertically up and down to adapt to the heights of different cross-sections, and the rising height can be higher than the top surface of the material, so that the pinch roller will not interfere with the material placed on the feeding roller path during the return journey. The cutting machine frame at the cutting station can move vertically, enabling the geometric center of the cutting vertical surface to coincide with the geometric center of the material cross-section. The cutting torch makes a circular, radial and tangential composite movement relative to the geometric center through a sliding rail group that can move perpendicular to each other and is assembled on the turntable, so as to take into account the processing of different cross-sectional shapes of pipes and profiles.

Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe composite cutting, and specifically to a steel pipe composite cutting device. Background Art

[0002] In the components of various steel structure buildings or structures, steel pipes (such as round pipes, polygonal pipes, square rectangular pipes, etc.) and steel profiles (such as H-shaped steel, T-shaped steel, channel steel, etc.) are often used for manufacturing and processing. One of the processes is to use cutting equipment to perform the required cutting on the materials.

For example, a numerical control pipe cutting machine is used for cutting round pipes, and a numerical control section steel cutting machine is used for cutting section steel. Generally, both of these two types of equipment need to be equipped in a steel structure factory. Since the materials used for steel components are different and the probability of processing components using steel pipes and section steel simultaneously for a long time is not high, there will be a phenomenon that one piece of equipment is in production while the other is idle.

[0031] In summary, as Figures 1-6 shown, when using this steel pipe composite cutting equipment, in step one, import the model cross-section specifications, length, cutting parts, cutting shapes, etc. of the workpiece to be processed into the controller that controls the operation of the machine. All moving parts of the equipment are in the initial state at the origin position. Among them, roller one 12.1 and roller 12.2, roller two 21.1 and roller two 21.2 are selected according to the model of the workpiece to be processed.

[0032] In step two, manually lift a material corresponding to the model and place it in the predetermined area on the material input roller path group one 11, and then start the machine to run.

[0033] In step three, the power cylinder 14.3 of the upright rod transmission mechanism 14 automatically drives each pair of side push upright rods 12 to symmetrically translate along the vertical plane of the longitudinal axis of the equipment unit according to the program instruction. After centering the material, the power cylinder 14.3 automatically locks in position; at the same time, the cutting bracket 2 automatically moves vertically according to the program instruction so that the circular hole axis line of its rotating plate wheel seat 2.3 coincides with the cross-sectional geometric center line of the material; at the same time, the side support rod transmission mechanism 23 in the workpiece output roller path area automatically drives each pair of side support rods 21 to symmetrically translate horizontally along the vertical plane of the longitudinal axis of the equipment unit according to the program instruction under the automatic drive of the transmission gear set 25 and the shaft transmission motor reducer 26, and automatically pauses when the symmetric spacing is slightly wider than the workpiece width at a position suitable for guiding the workpiece width.

[0034] In step four, after the material is centered, the numerical control clamp conveyor 15 automatically searches for the end of the material according to the program instruction, and at the same time the clamping device 16 moves downward. They cooperate with the gripper 17 to automatically clamp the predetermined position at the end of the material; then automatically push the material to move towards the cutting vertical plane position of the cutting torch 6, and automatically pause when the part to be cut on the material reaches the cutting point position (it will move back and forth when cutting the circular pipe intersection line).

[0035] In step five, according to the program instruction, the cutting power supply and the cutting torch 6 start cutting operation. The rotating plate 4 and the cutting torch slide rail group 5 cooperate with the cutting torch 6 to automatically cut the required end parts of the material such as bevels, cutting straight lines or curves, cutting off heads, etc. and certain parts of the segment length such as opening holes, bevels, segmenting, etc. along the predetermined trajectory, and the movement of the cutting longitudinal part is automatically clamped by the numerical control clamp conveyor 15 to move the material forward or backward (such as cutting a curve on the material surface); when the rotating plate 4 makes a clockwise or counterclockwise circular motion, the cable 6.1 will be pulled out or retracted from the cable reel 7; the cut slag and cut-off heads will fall into the receiving cart 29.

[0036] [[ID=!7]]In step six, when a cut workpiece of a certain length enters the workpiece output roller path group two 20, after the workpiece is segmented, the program instruction chain drive motor reducer 27 starts to run, and the chain drive motor reducer 27 automatically drives the roller path group two 20 to convey the workpiece to the end of the roller path and pause, and the workpiece waits to be removed from the roller path.

[0037] Step 7: When cutting the tail end of a piece of material, according to the program instructions, the centering rod drive mechanism 14 within the material input roller path area automatically drives each pair of side push centering rods 12 to reset, and then an operator manually lifts and places the next piece of material onto the first input roller path group 11; after the cutting of the previous piece of material is completed, the grippers 17 on the clamping device 16 automatically release the clamp through the cylinder 17.1, the clamping device 16 automatically rises and resets through the second drive motor 16.1, and the feeding device 15 automatically returns after riding over the material; at the same time, the rotating plate 4 and the cutting torch slide rail group 5 drive the cutting torch 6 to automatically reset. Thus, the cutting work cycle of one piece of material is completed.

[0038] Step 8: After the workpiece of the previously cut piece placed on the workpiece output roller path group two 20 is removed, the command transmission gear set 25 and the shaft transmission motor reducer 26 drive the side centering rod drive mechanism 23 to reset each pair of side centering rods 21.

[0039] Finally, by repeating the process of the above steps 1 - 8, the cutting work cycle of subsequent materials can be completed;

[0040] In addition, the program control instruction logic is as follows: Program control logic: Before the equipment starts, the numerical control feeding device 15, the clamping device 16, the cutting support 2, the rotating plate 4, the cutting torch 6, the side push centering rods 12, and the side centering rods 21 are all in the initial state at the origin position - import the model cross-section specifications, length, cutting parts, cutting shapes, etc. of the workpiece to be processed into the controller - start the machine after the material is lifted and placed on the first material input roller path group 11 - the centering rod drive mechanism 14 automatically drives the side push centering rods 12 to center the material, and then the power cylinder 14.3 automatically locks in place; at the same time, the cutting support 2 automatically moves vertically so that the circular hole axis line of its rotating plate wheel seat 2.3 coincides with the cross-section geometric center line of the material; at the same time, the side centering rod drive mechanism 23 within the workpiece output roller path area automatically drives the lateral spacing of the side centering rods 21 to be in the guiding position suitable for the width of the workpiece - the numerical control feeding device 15 automatically locates to the tail end of the material and cooperates with the clamping device 16 to automatically clamp the material - the numerical control feeding device 15 automatically pushes the cutting part of the material step by step to the working position of the cutting torch 6 and pauses, or when pushing and pulling to cut the intersecting line of circular tubes - the rotating plate 4, the cutting torch slide rail group 5, the cutting power supply, and the cutting torch 6 cooperate with each other to start the cutting operation - the cut workpiece segment enters the workpiece output roller path group two 20, and after the workpiece segmentation segment, the chain drive motor reducer 27 automatically drives the roller path group two 20 to convey the workpiece to the end of the roller path and pauses - when cutting the tail of the previous piece of material, the centering rod drive mechanism 14 automatically drives the side push centering rods 12 to reset - lift and place the next piece of material onto the first material input roller path group 11 - the clamping device 16 that has completed the cutting work of the previous piece of material automatically releases the clamp, the numerical control feeding device 15 automatically returns, and the rotating plate 4 and the cutting torch 6 automatically reset - after the cutting work cycle of one piece of material is completed, the machine automatically shuts down and awaits the next cycle.

[0041] When the material is lifted and placed on the input roller table 11,

[0042] 1. The program commands the power cylinder 14.3 of the alignment rod drive mechanism 14 to drive each pair of side push alignment rods 12 to simultaneously and symmetrically move towards each other horizontally, causing the material to be centered horizontally and coincide with the longitudinal central vertical plane of the equipment unit;

[0043] 2. At the same time, the program commands the side support positioning motor reducer 9 to drive the cutting bracket 2 to move vertically, so that the axis line of the circular hole of the rotating plate wheel seat 2.3 coincides with the geometric center line of the cross-section of the material;

[0044] 3. At the same time, the program commands the side support rod drive mechanism 23 within the workpiece output roller table area to automatically drive the lateral spacing of the side support rods 21 to be in a guiding position suitable for the width of the workpiece.

[0045] 3.2.1. The program commands the numerical control pinch roller 15 near the origin at the tail end of the material to automatically move to the tail end of the material, and the clamping device 16 thereon automatically moves vertically to a position where it can clamp the end of the material and cooperates with the gripper 17 to clamp the material; then it automatically pushes the material to move towards the cutting vertical plane position of the cutting torch 6. When the part to be cut on the material reaches the cutting point, the material will automatically pause and the cutting line on the material surface will move back and forth.

[0046] 3.2.2. The program commands the cutting power supply and the cutting torch 6 to start cutting operation. The rotating plate 4 and the cutting torch slide rail group 5 cooperate with the cutting torch 6 to automatically cut the required end parts of the material such as bevels, straight or curved cuts, and cut-offs, and certain parts of the segment length such as openings, bevels, and segmentation, etc. along the predetermined trajectory. And the movement of the cutting longitudinal part is automatically clamped and advanced or retreated by the numerical control pinch roller 15; the cutting slag and cut-off heads fall into the receiving cart 29.

[0047] 3.2.3. When a cut workpiece of a certain length enters the second workpiece output roller table group 20 and after the workpiece segmentation section, the program commands the chain drive motor reducer 27 to start running. The chain drive motor reducer 27 automatically drives the second workpiece output roller table group 20 to convey the workpiece to the end of the roller table and pause, and the workpiece waits to be removed from the roller table.

[0048] 3.2.4. When a material is at the cutting tail end, the program commands the alignment rod drive mechanism 14 to automatically drive the side push alignment rods 12 to reset, and then a new material can be lifted and placed on the first input roller table group 11; the gripper 17 on the clamping device 16 that has completed the cutting work of the previous material automatically releases the clamp through the cylinder 17.1, and the clamping device 16 automatically rises and resets through the drive motor two 16.1. At the same time, the numerical control pinch roller 15 rides over the material and automatically returns to its original position; the rotating plate 4 and the cutting torch slide rail group 5 drive the cutting torch 6 to automatically return to its original position. Thus, the cutting work cycle of one material is completed.

[0049] 3.2.5 After the previous workpiece cut and placed on the workpiece output roller group II 20 is removed, an instruction is given to the drive gear group 25 and the shaft drive motor reducer 26 to drive the side support rod drive mechanism 23 to reset each pair of side support rods 21.

[0050] Finally, repeat the above processes of 3.2.1 to 3.2.5 to complete the cutting work cycle of the subsequent materials.
