Description

Technical Field

[0001] This utility model relates to the field of pipe bending machine technology, specifically a pipe bending machine that can bend left and right by changing the upper and lower molds. Background Technology

[0002] In the field of metal pipe processing, pipe bending equipment is the core equipment for realizing pipe bending and forming. Traditional pipe bending machines often face many technical bottlenecks in practical applications: First, for processing tasks that require different bending radii or angles, it is often necessary to frequently stop the machine and manually change the mold (pipe bending mold), which is cumbersome, time-consuming and labor-intensive, and seriously affects production efficiency.

[0003] Secondly, most equipment only has the ability to bend pipes in one direction (such as only bending to the left or right). For pipe processing with complex spatial orientation, multiple clamping or multiple machines are often required, which not only increases costs and processing errors, but also limits the versatility and flexibility of the equipment. Furthermore, the accuracy and convenience of pipe feeding and positioning directly affect the quality of pipe bending. Traditional manual or semi-automatic feeding methods are difficult to quickly and accurately deliver pipes to the variable starting position of the bend, which is particularly prominent in mass or diversified production.

[0024] Please see Figures 1-4This utility model discloses a pipe bending machine with up-and-down mold changing and left-and-right bending, comprising a frame body 1; a feeding assembly 2 is bolted to the side of the frame body 1; a sprocket 3 is bolted to the top front side of the frame body 1; a chain 4 is driven on the sprocket 3; the front and rear ends of the chain 4 are respectively fixed to the back of a first sliding plate 5 and the top of a counterweight 8; a limit post 7 is bolted to the front inner side of the frame body 1, and a counterweight 8 is slidably arranged on the outer side of the limit post 7; a first transmission head assembly 11 is bolted to the left front end of the first sliding plate 5, and the first sliding plate 5 is slidably arranged on the front side of the frame body 1 via a slide rail 9; a horizontal rail is bolted to the front end of the first sliding plate 5, and a second sliding plate 10 is slidably arranged on the horizontal rail; a second transmission head assembly 12 is bolted to the left front end of the second sliding plate 10.

[0025] A housing is fixedly installed on the front right side of the second sliding plate 10, and a third transmission head assembly 13 is fixedly installed inside the housing; a pipe bending head 6 is driven at the front end of the third transmission head assembly 13.

[0026] The third transmission head assembly 13 specifically consists of a servo motor, a coupling fixed on the output shaft of the servo motor, and two sets of bevel gears fixed at the end of the coupling. The driven bevel gear in the two sets of bevel gears of the third transmission head assembly 13 is fixedly connected to the rotating rod of the pipe bending head 6.

[0027] The counterweight 8 is a rectangular metal block with a through hole in the center that matches the outer diameter of the limiting post 7. A self-lubricating bushing is embedded in the through hole. The top of the counterweight 8 is provided with a U-shaped lug, and the rear end of the chain 4 is hinged to the lug via a pin.

[0028] Example 2:

[0029] Please see Figures 1-4 The present invention provides a pipe bending machine for changing molds up and down and bending left and right. Compared with the first embodiment, this embodiment also includes: the feeding component 2 specifically consists of a fourth transmission head component 21 and a front slide rail 22 that are fixedly installed on the side of the main body 1 of the frame by bolts.

[0030] The fourth transmission head assembly 21 is specifically composed of a servo motor, a gear fixed to the end of the servo motor's drive shaft, and a rack meshing below the gear; the rack is fixedly installed on the side wall of the main frame 1.

[0031] The first transmission head assembly 11 and the second transmission head assembly 12 have the same structure as the fourth transmission head assembly 21, and are set at 90 degrees perpendicular to each other to form a three-axis adjustment.

[0032] The working principle of a pipe bending machine that involves changing molds up and down and bending left and right is as described above:

[0033] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.

[0034] Secondly, during pipe bending, the worker loads the pipe to be processed onto the loading assembly 2 and passes it through the frame fixed to the fourth transmission head assembly 21. The servo motor in the fourth transmission head assembly 21 drives the gears and racks at its shaft end to mesh, causing the fourth transmission head assembly 21 to slide along the side of the main frame 1 for loading. Here, the worker controls the first transmission head assembly 11 and the second transmission head assembly 12 to operate according to the pipe to be processed. When the servo motor in the first transmission head assembly 11 drives the gears and racks at its shaft end... When the wheel and rack mesh, the first sliding plate 5 is vertically slidable at the front end of the frame body 1 under the limiting action of the slide rail 9. When the servo motor in the second transmission head assembly 12 drives the gear and rack at its shaft end to mesh, the second sliding plate 10 is slidably disposed in the left and right direction in front of the first sliding plate 5, thereby changing the spatial position of the pipe bending head 6 to adapt to pipes of different specifications to be processed. Subsequently, the servo motor in the third transmission head assembly 13 drives the two sets of bevel gears at its shaft end to mesh, thereby driving the pipe bending head 6 to rotate and perform the pipe bending action.

[0035] This utility model provides an improved pipe bending machine with up-and-down mold changing and left-and-right bending. The servo motor in the fourth transmission head assembly 21 drives the gear and rack to mesh and achieve automatic sliding feeding along the side of the main frame 1. At the same time, the first transmission head assembly 11 controls the vertical movement of the first sliding plate 5 at the front end of the main frame 1, and the second transmission head assembly 12 drives the second sliding plate 10 to move left and right in the horizontal direction. This coordinates the precise positioning of the pipe bending head 6 in three-dimensional space, thereby adapting to the processing requirements of pipes of different specifications. Finally, the third transmission head assembly 13 drives the pipe bending head 6 to rotate through bevel gear transmission to complete the high-precision pipe bending action.
