Description

Technical Field

[0001] This utility model relates to the field of metal pipe processing technology, and in particular to a bending machine for processing metal pipes. Background Technology

[0002] Metal pipe fittings are components made of metal materials. They have a wide range of applications, including medical, manufacturing, construction, and transportation. The shape of metal pipe fittings varies depending on the equipment used, requiring bending of the metal material to achieve the desired shape. Bending of metal pipe fittings requires the use of bending machinery. The use of bending machines can significantly improve the efficiency of bending metal pipe fittings while also enhancing safety during the processing.

[0003] A search revealed Chinese patent CN220942669U, which discloses a bending machine for metal processing. The machine includes a base, a lower die mounted on the base, an upper die positioned opposite the lower die, and a worktable located outside the lower die. An adjustment groove is formed on the worktable, and an adjustment assembly is installed inside the groove. Two sliding components are mounted on the adjustment assembly, each with a telescopic rod at its sliding end. This invention, by using a fixing clamp, allows the telescopic rod and sliding components to adjust according to the angle of the metal during bending. The rotating fixing clamp changes with the angle of the metal as it bends, maintaining constant fixation. This eliminates the need for workers to manually hold the metal during bending, protecting worker safety by avoiding the force exerted on their hands during bending.

[0004] This patent only solves the problem of manual handling of metal pipes, but it cannot quickly measure and locate the bending points of the metal pipes. Using manual step-by-step calibration of the points can easily lead to large positioning errors at the bending points. Furthermore, it cannot bend multiple metal pipes simultaneously, which can result in low bending efficiency and is not conducive to improving the practicality of the bending machine. Utility Model Content

In addition, it cannot bend multiple metal pipes at the same time, which can easily lead to low bending efficiency and is not conducive to improving the practicality of bending machines. This utility model provides a bending machine for processing metal pipes.

[0006] The technical solution adopted in this utility model is: a bending machine for processing metal pipe fittings, comprising:

[0011] Furthermore, the bending assembly includes a folding plate fixedly installed between the two slide rails and located below the baffle, a base plate located below the baffle, two symmetrically installed telescopic rods one and two symmetrically installed telescopic rods two.

[0013] Furthermore, a limiting plate is fixedly installed above the workbench, and the folding plate and the limiting plate are respectively located on both sides below the pressure shaft.

[0014] Furthermore, the workbench is fixedly equipped with support legs underneath.

[0026] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0027] In order to solve the problems existing in the background art, this application proposes the following technical solution: a bending machine for processing metal pipe fittings.

[0028] The specific technical solution includes symmetrically installed slide rails 1, fixed-point limiting components 2, and positioning rulers 3;

[0029] like Figure 1-4 As shown, the fixed-point limiting component 2 is installed above the slide rail 1. The fixed-point limiting component 2 is used to fix the bending point of the metal pipe. The fixed-point limiting component 2 includes a baffle 201 located above the two slide rails 1 and two top blocks 202 located inside the two slide rails 1 respectively. The baffle 201 can be used to limit the metal pipe, and the top blocks 202 can connect the baffle 201 and the slide rail 1. A pulley 203 located inside one slide rail 1 is installed below one top block 202, and a bottom block 204 located inside the other slide rail 1 passes through the other top block 202. The pulley 203 can reduce the resistance when the top block 202 moves, and the bottom block 204 can limit the bottom of the spring 205 ear. The bottom block 204 is equipped with a spring 205 that passes through the top block 202 and a pressure plate 206 is fixedly installed on the side wall. The spring 205 can push the bottom block 204 downward, and the pressure plate 206 can make it easy to press the bottom block 204 by hand. The positioning ruler 3 is fixedly installed on the top surface of the slide rail 1 that is sleeved on the outside of the bottom block 204 and is located below the baffle 201. The positioning ruler 3 can measure the end of the metal pipe to the part that needs to be bent.

[0030] When it is necessary to measure the bending point on a metal pipe fitting, the distance from the end of the metal pipe fitting to the part to be bent is determined. This distance is called the fixed point length. When the bottom surface of the bottom block 204 contacts the inner bottom surface of the slide rail 1, the spring 205 is in a compressed state and can press the bottom block 204 downward. By manually moving the pressure plate 206, the pressure plate 206 drives the bottom block 204 to rise. The bottom block 204 moves upward and presses the spring 205. The spring 205 is compressed and generates a downward pushing force on the bottom block 204. By manually pushing the pressure plate 206 and the baffle 201 to move, the baffle 201 and the pressure plate 206 respectively drive the top block 202 and the bottom block 204 to move. The top block 202 and the bottom block 204 respectively drive the pulleys. 203 rotates and spring 205 moves, pushing baffle 201 to the same scale on positioning ruler 3 as the fixed length data. The pressure plate 206 is released, the bottom block 204 descends and spring 205 presses down on the bottom block 204. The bottom surface of the bottom block 204 presses against the inner bottom surface of the slide rail 1, which can increase the frictional resistance between the bottom block 204 and the slide rail 1. The bottom block 204 is fixed and can drive the top block 202 to be fixed. The top block 202 can drive the baffle 201 to be fixed. The metal tube is inserted between the pressure shaft 405 and the bending plate 401, so that the measured end of the metal tube is pressed against the baffle 201. At this time, the part on the metal tube below the pressure shaft 405 is the bending point of the metal tube that needs to be bent.

[0031] like Figure 1-2 and Figure 4As shown, a bending assembly 4 is installed below the slide rail 1. The bending assembly 4 is used to bend metal pipe fittings. The bending assembly 4 includes a folding plate 401 fixedly installed between the two slide rails 1 and located below the baffle 201, a base plate 402 located below the baffle 201, two symmetrically installed telescopic rods 403 and two symmetrically installed telescopic rods 404. The folding plate 401 can support the bottom of the metal pipe fitting, and the base plate 402 can support the telescopic rods 403 and 404. The bottom of the second rod 404 is supported, the first telescopic rod 403 can push the folding plate 401 upward, the second telescopic rod 404 can drive the pressure shaft 405 to rise and fall, the telescopic end of the first telescopic rod 403 is rotatably connected to the bottom surface of the folding plate 401 and the fixed end is rotatably connected to the top surface of the base plate 402, the fixed end of the second telescopic rod 404 is fixedly installed on the top surface of the base plate 402 and the telescopic end is fixedly installed with the pressure shaft 405, the pressure shaft 405 can press the top of the metal pipe.

[0032] Multiple metal pipes are arranged and placed below the pressure shaft 405 in the manner described above. The metal pipes are located above the bending plate 401. The base plate 402 can support the bottom of the telescopic rod 1 403 and the telescopic rod 2 404, facilitating the raising and lowering of the telescopic ends of the telescopic rod 1 403 and the telescopic rod 2 404. By activating the telescopic rod 2 404, the pressure shaft 405 is driven to descend. The pressure shaft 405 can press on the metal pipes, fixing the parts of the metal pipes that need to be bent and the parts away from the bending plate 401. By activating the telescopic rod 1 403, the bending plate 401 is pushed upward. The bending plate 401 rotates around the central axis of the connection with the worktable 5. The upward rotation of the bending plate 401 causes a section of the metal pipe on the bending plate 401 to bend upward. The section of the metal pipe on the bending plate 401 bends and rotates upward around the central axis of the pressure shaft 405, and the metal pipe can be bent.

[0033] like Figure 1-2 As shown, a worktable 5 is rotatably mounted below the folding plate 401 and located below the pressure shaft 405. The worktable 5 can support the folding plate 401. A through hole 6 is provided on the worktable 5 and sleeved on the outside of the telescopic rod 403. The through hole 6 can facilitate the connection between the telescopic rod 403 and the folding plate 401.

[0034] like Figure 1 As shown, a limiting plate 7 is fixedly installed above the workbench 5. The limiting plate 7 can limit and support the fixed end of the metal pipe fitting. The folding plate 401 and the limiting plate 7 are located on the lower sides of the pressure shaft 405, respectively.

[0035] like Figure 1-2 As shown, a support leg 8 is fixedly installed under the worktable 5, which can support the worktable 5.

[0036] like Figure 2As shown, the bottom of the support leg 8 is fixedly equipped with a bracket 9 that is fixedly connected to the bottom surface of the base plate 402. The bracket 9 can support and fix the base plate 402.
