Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to an automatic square pipe cutting equipment. Background Technique

[0002] Square pipe cutting is an important technology in the field of metal processing and is widely used in many industries such as construction, machinery, automobiles, and ships. Square pipe cutting can adopt various methods, including mechanical cutting, flame cutting, laser cutting, etc. Among them, mechanical cutting uses mechanical devices (such as saw blades and blades) to cut square pipes, flame cutting heats square pipes through the high-temperature flame generated by the mixture combustion of gas and oxygen, melts them and blows away the molten slag to achieve cutting, while laser cutting irradiates square pipes with a laser beam with a high energy density, locally melts and evaporates them, and at the same time uses high-pressure gas to blow away the molten metal to achieve cutting.

[0003] Most of the existing cutting equipment requires manual feeding of pipe fittings. Workers need to manually place the square pipes on the cutting table and use tools such as jigs to fix their positions to prevent them from shifting when sent to the cutting machine and affecting the cutting effect. Moreover, different from round pipes, when placing square pipes, they need to be placed correctly, otherwise it will affect the clamping effect and further bring inconvenience to the feeding work, thereby affecting the overall efficiency of the cutting work. Therefore, in view of the above problems, an automatic square pipe cutting equipment is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an automatic square pipe cutting equipment. The cutting equipment can centrally store several square pipes in an automatic feeding box, and the spring pushing mechanism arranged on it can apply a thrust to the square pipes, so that the innermost square pipe can fit the bottom of the material groove, which has a positioning effect. When the feeding mechanism works, it can push the square pipe fitting the bottom of the material groove towards the gantry laser cutting machine to complete cutting. And after the current square pipe is completely pushed out, the tension spring in the spring pushing mechanism pulls the L-shaped push plate to move, and pushes the next square pipe to the position where it fits the bottom of the material groove, which is convenient for the feeding mechanism to perform the next pushing work. The whole process can realize automatic feeding and material delivery, and has a positioning effect. At the same time, there is no need to use a jig to limit the square pipe, which improves the overall efficiency of the cutting work and significantly reduces the labor intensity of workers, and solves the technical problems that most of the existing cutting equipment requires manual feeding and positioning and fixing of pipe fittings, and the square pipes need to be placed correctly when placed, which affects the overall efficiency of the cutting work and increases the work burden of workers at the same time.

[0005] The technical solution adopted by the embodiment of the present application to solve its technical problems is:

[0006] A square pipe automatic cutting device includes a workbench plate, on which an automatic feeding box, a guide plate, and a gantry laser cutting machine are sequentially installed from front to back, and a feeding mechanism for pushing the pipe fittings towards the gantry laser cutting machine. Among them, a material groove is provided in the automatic feeding box, in which the pipe fittings are placed. A spring pushing mechanism is provided on the automatic feeding box. The spring pushing mechanism includes a guide rail, in which a sliding plate is slidably provided. The lower end surface of the sliding plate is fixedly connected with an L-shaped pushing plate for pushing materials. A tension spring is fixedly connected to the sliding plate, and the end of the tension spring away from the sliding plate is detachably connected to the end plate of the guide rail.

[0007] Through the above structural form, a number of square pipes can be centrally stored in the automatic feeding box. The spring pushing mechanism provided thereon can apply a thrust to the square pipes, so that the innermost square pipe can fit against the bottom of the material groove, which has a positioning function. When the feeding mechanism works, it can push the square pipe that fits against the bottom of the material groove towards the gantry laser cutting machine to complete the cutting. And after the current square pipe is completely pushed out, the tension spring in the spring pushing mechanism pulls the L-shaped pushing plate to move, pushing the next square pipe to a position where it fits against the bottom of the material groove, facilitating the feeding mechanism to perform the next pushing operation. The whole process can realize automatic feeding and has a positioning function. At the same time, there is no need to use a fixture to limit the square pipe, which improves the overall efficiency of the cutting work and significantly reduces the labor intensity of the workers.

[0008] In a possible implementation manner, both sides of the end of the automatic feeding box away from its opening are provided with discharge ports, and the cross-sectional size of the discharge ports is consistent with the cross-sectional size of the pipe fittings.

[0009] Through the above structural form, the provided discharge ports provide a necessary structural basis for the pushing out of the square pipes, and the size of the discharge ports is consistent with the size of the pipe fittings, which can play a role in limiting and constraining the pipe fittings when they are sent out, avoiding their deviation during the sending out process.

[0010] In a possible implementation manner, the feeding mechanism includes a slide rail fixedly installed on the workbench plate and a driving motor. A sliding pusher is slidably provided in the slide rail. The output shaft of the driving motor is fixedly connected with a transmission lead screw, and the transmission lead screw passes through the sliding pusher and is threadedly connected thereto.

[0011] Through the above structural form, the driving motor can be made to work to drive the transmission lead screw to rotate, and then drive the sliding pusher threadedly connected to the transmission lead screw to slide back and forth, realizing the functions of pushing and resetting.

[0012] In a possible implementation manner, the sliding pusher includes a slide table threadedly connected to the transmission lead screw. The upper end surface of the slide table is rotatably connected with a rotating pushing plate through a hinge seat. At the same time, a limiting block is provided on the upper end surface of the slide table.

[0013] With the above structural form, when the sliding table moves forward, the rotating push plate contacts the square pipe and applies a thrust to push it towards the gantry laser cutting machine. At the same time, since the rotating push plate can rotate, it will contract inward under pressure when returning, so that it will not interfere with the return journey.

[0014] In a possible implementation, when the rotating push plate is perpendicular to the upper end face of the sliding table, the rotating push plate is in close contact with the limit block.

[0015] With the above structural form, it can ensure that the rotating push plate is in a vertical state when pushing materials, has sufficient contact area with the square pipe, and ensures the stability during material pushing.

[0016] In a possible implementation, the rotating shaft of the rotating push plate connected to the hinge seat extends out of the hinge seat, and a connecting end piece is fixedly connected to the end of the rotating shaft. A return torsion spring is sleeved outside the rotating shaft, and both ends of the return torsion spring are fixedly connected to the hinge seat and the connecting end piece respectively.

[0017] With the above structural form, when the sliding table moves backward, the rotating push plate contracts inward under pressure when returning, and when the rotating push plate is no longer under pressure, it will bounce and rotate under the action of the return torsion spring until it is in close contact with the limit block and returns to its original position.

[0018] In a possible implementation, a mating groove is provided on the lower end plate body of the automatic loading box. Both sides of the mating groove communicate with the discharge port, and a limit ring is provided in the discharge port far from the gantry laser cutting machine.

[0019] With the above structural form, the opening of the mating groove provides a necessary structural basis for the continuous contact between the rotating push plate and the square pipe, while the limit ring can limit the sliding direction of the square pipe, preventing the square pipe from sliding backward when the rotating push plate moves backward and affecting the subsequent normal feeding.

[0020] In a possible implementation, a centrally arranged dial is fixedly provided on the upper end face of the sliding plate.

[0021] With the above structural form, it is convenient for workers to pull the sliding plate by the dial to slide it out of the guide rail, thereby providing a necessary structural basis for workers to place square pipes into it.

[0022] In summary, the present utility model has the following beneficial technical effects:

[0023] The automatic loading box centrally stores a number of square pipes. The provided spring pushing mechanism can apply a thrust to the square pipes, making the innermost square pipe fit the bottom of the material trough, which has a positioning function. When the feeding mechanism works, it can push the square pipe fitting the bottom of the material trough towards the gantry laser cutting machine, thus automatically completing the entire process of feeding and cutting.

[0024] After the current square tube is completely pushed out, the tension spring in the spring feeding mechanism pulls the L-shaped push plate to move, pushing the next square tube to a position where it fits against the bottom of the material trough, facilitating the next feeding operation of the feeding mechanism. The entire process can achieve automatic feeding and material delivery, without the need to use a fixture to limit the square tube, improving the overall efficiency of the cutting work and significantly reducing the labor intensity of workers.

Detailed Description of the Invention

[0032] The technical solutions in the embodiments of the present application are to solve the problems in the above background technology, and the general idea is as follows:

[0033] As Figure 1 - Figure 2As shown in the figure, an automatic square pipe cutting device provided in this embodiment includes a workbench plate 1, on which an automatic feeding box 2, a guiding plate 5, and a gantry laser cutting machine 4 are sequentially installed from front to back, and a feeding mechanism 3 for pushing the pipe fittings towards the gantry laser cutting machine 4. Among them, a material groove 21 is opened in the automatic feeding box 2, and pipe fittings are placed therein. A spring pushing mechanism 22 is provided on the automatic feeding box 2. Through the above structural form, a number of square pipes can be centrally stored in the automatic feeding box 2, and the spring pushing mechanism 22 provided thereon can apply a thrust to the square pipes, so that the innermost square pipe can fit against the bottom of the material groove 21, having a positioning function. When the feeding mechanism 3 works, it can push the square pipe that fits against the bottom of the material groove 21 towards the gantry laser cutting machine 4 to complete the cutting. And after the current square pipe is completely pushed out, the spring pushing mechanism 22 can push the next square pipe to a position where it fits against the bottom of the material groove 21, facilitating the next pushing operation of the feeding mechanism 3.

[0034] As Figure 4 shown in the figure, the spring pushing mechanism 22 includes a guide rail 221, in which a sliding plate 222 is slidably provided. A downward end surface of the sliding plate 222 is fixedly connected with an L-shaped pushing plate 223 for pushing materials. A tension spring 224 is fixedly connected to the sliding plate 222, and an end of the tension spring 224 away from the sliding plate 222 is detachably connected to an end plate of the guide rail 221. Through the above structural form, the tension spring 224 can apply a pulling force to the L-shaped pushing plate 223, and then apply a thrust to the square pipe, so that the innermost square pipe can fit against the bottom of the material groove 21, having a positioning function. After the current square pipe is completely pushed out, the tension spring 224 pulls the L-shaped pushing plate 223 to move, and pushes the next square pipe to a position where it fits against the bottom of the material groove 21, facilitating the next pushing operation of the feeding mechanism 3.

[0035] As Figure 5 shown in the figure, both sides of one end of the automatic feeding box 2 away from its opening are provided with discharge ports 23, and a cross-sectional dimension of the discharge ports 23 is consistent with a cross-sectional dimension of the pipe fittings. Through the above structural form, the provided discharge ports 23 provide a necessary structural basis for the pushing out of the square pipes, and the dimensions of the discharge ports 23 are consistent with the dimensions of the pipe fittings, which can play a role in limiting and constraining the pipe fittings when they are sent out, avoiding their deviation during the sending-out process.

[0036] As Figure 3 shown in the figure, the feeding mechanism 3 includes a slide rail 31 fixedly installed on the workbench plate 1 and a driving motor 33. A sliding pusher 32 is slidably provided in the slide rail 31. An output shaft of the driving motor 33 is fixedly connected with a transmission lead screw 34, and the transmission lead screw 34 passes through the sliding pusher 32 and is threadedly connected thereto. Through the above structural form, when the driving motor 33 works to drive the transmission lead screw 34 to rotate, the sliding pusher 32 threadedly connected to the transmission lead screw 34 can be driven to slide back and forth, realizing the functions of pushing materials and resetting.

[0037] The cam 323 is in a state of being rotated with respect to the upper end face of the platform 321, and the cam 323 is in a state of being rotated with respect to the lower end face of the platform 321.

[0038] Based on the above structure, the rotating shaft connecting the rotating push plate 323 and the hinge seat 322 extends out of the hinge seat 322, and the end of the rotating shaft is fixedly connected to a connecting end plate 325, and the outer sleeve of the rotating shaft is provided with a return torsion spring 326, and the two ends of the return torsion spring 326 are respectively fixedly connected to the hinge seat 322 and the connecting end plate 325. Through the above structural form, when the slide 321 moves backward, the rotating push plate 323 is compressed and retracted when returning, and when the rotating push plate 323 is no longer compressed, it will bounce up and rotate under the action of the return torsion spring 326 until it is tightly fitted with the limit block 324 and returns to its original position.

[0039] like Figure 5 As shown, a matching groove 24 is provided on the lower end plate of the automatic feeding box 2, and the two sides of the matching groove 24 are connected with the discharge port 23, and a limiting ring 25 is provided in the discharge port 23 away from the gantry laser cutting machine 4. Through the above-mentioned structural form, the opening of the matching groove 24 provides a necessary structural basis for the continuous contact between the rotating push plate 323 and the square tube, and the limiting ring 25 can limit the sliding direction of the square tube, thereby preventing the square tube from sliding backward when the rotating push plate 323 moves backward and affecting the subsequent normal feeding.

[0040] like Figure 4 As shown, a centrally arranged paddle 225 is fixedly provided on the upper end surface of the sliding plate 222. The above-mentioned structural form makes it easy for workers to use the paddle 225 to pull the sliding plate 222 to slide out of the guide rail 221, thereby providing the necessary structural foundation for workers to place square tubes therein.

[0041] The use principle and use process of this utility model:

[0042] An automatic feeding box 2 is used to centrally store a number of square tubes. The spring pushing mechanism 22 can apply a thrust to the square tubes so that the innermost square tube can fit the bottom of the material trough 21, which has a positioning effect. When the feeding mechanism 3 is working, it can push the square tube fitting the bottom of the material trough 21 to the gantry laser cutting machine 4, thereby automatically completing the entire process of feeding and cutting. After the current square tube is completely pushed out, the tension spring 224 in the spring pushing mechanism 22 pulls the L-shaped pushing plate 223 to move, and pushes the next square tube to a position that fits the bottom of the material trough 21, which is convenient for the feeding mechanism 3 to carry out the next pushing work. The whole process can realize automatic loading and feeding, without the need to use a clamp to limit the square tube, thereby improving the overall efficiency of the cutting work and significantly reducing the labor intensity of manual labor.

[0043] In the above process, when the slide 321 moves backward, the rotating push plate 323 is squeezed by the square tube when returning and rotates inward, and when the rotating push plate 323 is no longer under pressure, it will bounce up and rotate under the action of the return torsion spring 326 until it fits tightly with the limit block 324 and returns to its original position, so that the next pushing work can continue.

[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
