Description

Technical Field

[0001] This application relates to the field of steel pipe cutting technology, and in particular to a steel pipe positioning and feeding device for a steel pipe cutting machine. Background Technology

[0002] A steel pipe cutting machine is a mechanical device specifically designed for cutting steel pipes. Existing steel pipe cutting machines mainly include manual steel pipe cutting machines, electric steel pipe cutting machines, and laser steel pipe cutting machines. Laser steel pipe cutting machines utilize the high energy density of a laser beam for cutting, offering advantages such as fast cutting speed and high-quality cuts.

[0003] In related technologies, the steel pipe is passed through a chuck and clamped during processing, and then cut using a laser head. However, the steel pipe melts during the laser cutting process. Although the steel pipe is cut, the two melted sections still stick together. It is necessary to apply a force perpendicular to the axis of the cut steel pipe after the cutting is completed to separate the two sections. Currently, this requires manual hammering of the steel pipe with tools to break it at the cut point, which is quite troublesome. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems in the prior art by proposing a steel pipe positioning and feeding device for a steel pipe cutting machine.

[0005] This application can be achieved through the following technical solution: a steel pipe positioning and feeding device for a steel pipe cutting machine, including a mounting frame, a pressure plate, and a vertical movement driver mounted on the mounting frame. The pressure plate is mounted on the output end of the vertical movement driver. A positioning plate that can contact the end face of the material is provided on the pressure plate. The positioning plate is arranged perpendicular to the pressure plate.

[0006] In the above technical solution, the positioning plate can contact the end face of the material to limit the distance from the end face of the material to the chuck, so as to ensure that the cutting position of the material is accurate. After the material is cut into two sections, the operator can start the vertical movement driver to drive the pressure plate to move down so that the pressure plate pushes one section of the material down, and the two sections of the material can be separated.

[0007] Furthermore, the mounting bracket includes a fixed bracket and a sliding bracket slidably mounted on the fixed bracket. The vertical movement driver is fixedly mounted on the sliding bracket, and the mounting bracket is provided with a horizontal movement drive assembly. The horizontal movement drive assembly is used to drive the sliding bracket to slide horizontally so as to change the distance between the positioning plate and the chuck.

[0008] In the above technical solution, the transverse drive component can drive the sliding frame to slide horizontally, so that the operator can adjust the position of the positioning plate according to the cutting requirements of different lengths of steel pipes.

[0009] Furthermore, the transverse drive assembly includes a lead screw rotatably mounted on a mounting bracket and a lead screw motor for driving the lead screw to rotate, the lead screw being threadedly connected to the sliding bracket.

[0010] In the above technical solution, the rotation of the lead screw can drive the sliding frame to slide along the length of the slide groove.

[0011] Furthermore, a sliding groove is provided on the fixed frame, and the sliding groove is slidably connected to the sliding frame. Two corrugated tubes are sleeved on the lead screw, and the two corrugated tubes are located on both sides of the sliding frame respectively. The two ends of the corrugated tubes in the length direction are installed on the side wall of the sliding frame and the inner side wall of the sliding groove respectively.

[0012] In the above technical solution, the bellows protects the lead screw, preventing dust from easily settling on it and affecting its use. Due to the bellows' expandable and contractible nature, the sliding frame allows the bellows to extend or shorten as the lead screw rotates.

[0013] Furthermore, the side wall of the chute is provided with an impurity outlet that communicates with the outside of the fixed frame, and the length of the impurity outlet is consistent with the length direction of the chute.

[0014] In the above technical solution, when impurities accumulate on the corrugated pipe, the staff can use a brush to clean the corrugated pipe. By setting an impurity passage, it is convenient for dust and other impurities accumulated at the bottom of the chute to leave the fixed frame through the impurity passage.

[0015] Furthermore, it also includes a suction hood connected to a suction tube.

[0016] In the above technical solution, an odor will be generated during the laser cutting of steel pipes. The suction tube can be installed to remove the odor elsewhere, ensuring the health of the workers.

[0017] Furthermore, it also includes a collection basket with several clips at the top, the clips holding a strap that can contact the inner bottom surface of the collection basket.

[0018] In the above technical solution, the collection basket can hold the cut steel pipes. After the steel pipes are piled up to a certain amount, the binding straps can be removed from the clamps to tie the steel pipes and then transport them.

[0019] Furthermore, the fixing frame is provided with scale lines, which are arranged along the length direction of the slide groove.

[0020] In the above technical solution, the scale lines make it easier for staff to determine the position of the sliding frame.

[0021] Furthermore, it also includes an air conditioner capable of delivering cold air to the material cut.

[0022] In the above technical solution, the air cooler can cool down the material during cutting to prevent the cut material from burning the workers.

[0023] In summary, this application has the following technical effects: the positioning plate can contact the end face of the material to limit the distance from the end face of the material to the chuck, so as to make the cutting position of the material accurate. After the material is cut into two sections, the operator can start the vertical movement driver to drive the pressure plate to move down so that the pressure plate pushes one section of the material down, and the two sections of the material can be separated.

Air conditioner; Detailed Implementation

[0028] Reference Figure 1 One embodiment of this application provides a steel pipe positioning and unloading device for a steel pipe cutting machine, including a mounting frame 1. The mounting frame 1 includes a fixed frame 11 placed on the ground. A sliding groove 111 is provided on the fixed frame 11. The sliding groove 111 is slidably connected to a sliding frame 12. The sliding frame 12 can slide along the length direction of the sliding groove 111. A vertical movement driver 3 is installed on the sliding frame 12. The vertical movement driver 3 can be any one of an electric actuator, a cylinder, or a hydraulic cylinder. A horizontally arranged pressure plate 2 is installed on the output end of the vertical movement driver 3. The pressure plate 2 is used to contact the outer wall of the material along its length direction. The material is a steel pipe. A vertically arranged positioning plate 4 is installed on the pressure plate 2. The positioning plate 4 is located at the end of the pressure plate 2 away from the chuck 6. The positioning plate 4 can contact the end face of the material to position the material.

[0029] In use, first fix one end of the steel pipe along its length onto the chuck 6, and make the end face of one end of the steel pipe abut against the positioning plate 4. Then use a laser to cut the steel pipe into two sections. After the steel pipe is cut into two sections, the two sections of the steel pipe will stick together due to the melting of the steel pipe. Then, turn on the vertical movement driver 3 to drive the pressure plate 2 to move down a certain distance so that the pressure plate 2 pushes down the section of the steel pipe that is close to the positioning plate 4, so that the two sections of the steel pipe are separated. Then, turn on the vertical movement driver 3 again to move the pressure plate 2 up the same distance so that the pressure plate returns to its original position.

[0030] Reference Figure 1 , 2 The mounting frame 1 is also equipped with a transverse drive assembly 5 for moving the sliding frame 12 along the length of the slide groove 111. The transverse drive assembly 5 includes a lead screw 51 rotatably mounted on the mounting frame 1 and a lead screw motor 52 for driving the lead screw 51 to rotate. The lead screw 51 is threadedly connected to the sliding frame 12. The rotation of the lead screw 51 can move the positioning plate 4 closer to or further away from the chuck 6. The operator can adjust the position of the positioning plate 4 according to the different cutting requirements of the steel pipe. The top of the fixed frame 11 is marked with scale lines, which are arranged along the length of the slide groove 111. The scale lines make it easy for the operator to determine the position of the sliding frame 12.

[0031] Reference Figure 1 Two corrugated tubes 7 are also fitted onto the lead screw 51. These two corrugated tubes 7 are installed one-to-one on opposite side walls of the sliding frame 12. The end of the corrugated tube 7 facing away from the sliding frame 12 is installed on the side wall of the slide groove 111. By setting the corrugated tubes 7, the outer wall of the corrugated tube 7 in the longitudinal direction can abut against the inner bottom surface of the slide groove 111, thus protecting the lead screw 51 and preventing dust from easily falling onto it and affecting its use. Because the corrugated tube 7 is telescopic, the sliding frame 12 can extend or shorten the corrugated tube 7 when the lead screw 51 rotates. An impurity outlet 8, communicating with the outside of the fixed frame 11, is provided on the bottom side wall of the slide groove 111. The length of the impurity outlet 8 is consistent with the length direction of the slide groove 111. When impurities accumulate on the corrugated tube 7, workers can use a brush to clean it. By providing an impurity outlet, dust accumulated at the bottom of the slide groove 111 can easily leave the fixed frame 11 through the impurity outlet.

[0032] Reference Figure 1 A suction hood 9 is installed on the fixed frame 11, and the suction hood 9 is connected to a suction pipe 10. A vacuum pump is installed inside the suction pipe 10. During the laser cutting of the steel pipe, an odor will be generated. The suction hood 9 and the suction pipe 10 can remove the odor elsewhere to ensure the health of the workers. A collection basket 13 is placed below the pressure plate 2. Two clamps 14 are installed on the top of each of the opposite side walls of the collection basket 13. The two opposite clamps 14 hold a strap 15. The strap 15 can contact the inner bottom surface of the collection basket 13. By setting the strap 15, the collection basket 13 can support the cut steel pipes. After the steel pipes are piled up to a certain amount, the strap 15 can be removed from the clamps 14 to tie the steel pipes and then transport them. A cooler 16 is placed next to the fixed frame 11. The cooler 16 can send cool air to the cut end of the steel pipe in the collection basket 13 to cool the cut end of the steel pipe.

[0033] The working principle of this embodiment is as follows: the positioning plate 4 can contact the end face of the material to limit the distance from the end face of the material to the chuck 6, so that the cutting position of the material is accurate. After the material is cut into two sections, the operator can start the vertical movement driver 3 to drive the pressure plate 2 to move down so that the pressure plate 2 pushes one section of the material down, and the two sections of the material can be separated.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
