Description

Technical Field

[0001] The utility model relates to the technical field related to pipe bending, and in particular to a pipe bending and wrinkle-proof integrated processing device. Background Art

[0002] Pipe bending is mainly done by pipe bending equipment, which is also called a bending machine. Two independent molds are usually installed on the pipe bending equipment, one is the mold for bending the pipe, and the other is the anti-wrinkle mold for protecting the pipe. Depending on the bending requirements of different pipes, it is sometimes necessary to repeatedly install and debug the mold, which takes a lot of time. Therefore, a pipe bending and anti-wrinkle integrated processing device is needed.

[0003] Existing pipe bending equipment needs to be re-debugged every time the mold is changed during use. For some parts with larger pipe diameters and smaller bending radius, repeated installation and debugging of the mold requires a lot of time and energy, sometimes even up to several hours. This is not only time-consuming and labor-intensive, but also consumes a large amount of raw materials in the process. Utility Model Content

[0004] The purpose of the present utility model is to provide an integrated pipe bending and wrinkle-proof processing device to solve the problem of the existing pipe bending equipment proposed in the above-mentioned background technology. During use, each time the mold is replaced, it needs to be re-debugged. For some parts with larger pipe diameters and smaller bending radii, repeated installation and debugging of the mold requires a lot of time and energy, sometimes even up to several hours, which is not only time-consuming and labor-intensive, but also consumes a large amount of raw materials in the process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pipe bending and wrinkle-proof integrated processing device, comprising a bending mold and an anti-wrinkle mold, one side of the bending mold is provided with an anti-wrinkle mold, and two ends of the bending mold surface are sleeved with bearings, the outer ring of the bearing is fixedly connected to the bearing sleeve, the side surface of the bearing sleeve is provided with a groove, one side of the surface of the bending mold is provided with a positioning hole, one end of the positioning hole is embedded with a positioning pin, one side of the bending mold is embedded with a positioning key, one side of the bending mold is fixedly connected to the mounting plate, one side of the mounting plate is provided with a connecting rod, one end of the connecting rod is welded with a stop key, one side of the stop key is fixedly connected to a T-shaped key, the surface of the T-shaped key is provided with a first threaded hole, one end of the T-shaped key is provided with a fixing plate, one side of the surface of the fixing plate is provided with a sliding groove, a fixing block is fixedly installed on one side surface of the fixing plate, and a second threaded hole is provided on one side surface of the anti-wrinkle mold.

[0006] Preferably, the position of the groove corresponds to the position of the positioning hole, and one end of the positioning pin protrudes out of the positioning hole and fits in the groove.

[0007] Preferably, the bending die forms a rotating structure through a bearing and a bearing sleeve, and the bearing sleeve and the anti-wrinkle die are both fixedly connected to the mounting plate.

[0008] Preferably, one side of the connecting rod fits into the slot on one side of the mounting plate, and the connecting rod is fixedly connected by a stop key and a T-key.

[0009] Preferably, the T-key forms a sliding structure with the fixed block through a sliding groove, the first threaded hole on the surface of the T-key is connected to the anti-rotation key through a fixing bolt, and the T-key and the fixed block are locked synchronously.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the pipe bending and wrinkle-proof integrated processing device fixes the anti-wrinkle mold on the mounting plate, and at the same time connects the bearing sleeve and the bearing on both sides of the mounting plate, so that the anti-wrinkle mold can fit on the side of the bending mold. When the bending mold rotates with the bending arm, the anti-wrinkle mold can still remain motionless, tightly attached to the inner side of the pipe wall, thereby preventing the pipe from wrinkling. Secondly, when the mold needs to be replaced, only the positioning pin needs to be inserted and the stop key needs to be removed to remove the mold, and the bending mold and the anti-wrinkle mold remain stationary with respect to each other. When the mold is used again, there is no need to readjust the fit between the bending mold and the anti-wrinkle mold, making the debugging of parts simpler and easier.

A positioning key 8 is embedded on one side of the bending die 1. One side of the anti-wrinkle die 2 is fixedly connected to a mounting plate 9. A connecting rod 10 is provided on one side of the mounting plate 9. A stop key 11 is welded on one end of the connecting rod 10. A T-shaped key 12 is fixedly connected to one side of the stop key 11. A first threaded hole 13 is provided on the surface of the T-shaped key 12. A fixing plate 14 is provided on one end of the T-shaped key 12. A sliding groove 15 is provided on one side of the surface of the fixing plate 14. A fixing block 16 is fixedly installed on the surface of one side of the fixing plate 14. A second threaded hole 17 is provided on the surface of the anti-wrinkle die 2

[0020] Furthermore, the position of the groove 5 corresponds to the position of the positioning hole 6, and one end of the positioning pin 7 protrudes from the positioning hole 6 and fits the groove 5. Through the setting of the positioning pin 7, the positioning pin 7 is only used during disassembly. When bending, the engagement of the connecting rod 10 and the mounting plate 9 will form a limiting structure. When disassembly is required, it is only necessary to embed the positioning pin 7 from one end of the groove 5 into the positioning hole 6 to complete the limiting of the anti-wrinkle mold 2.

[0021] Furthermore, the bending die 1 forms a rotating structure through the bearing 3 and the bearing sleeve 4. The bearing sleeve 4 and the anti-wrinkle die 2 are fixedly connected to the mounting plate 9. Through the setting of the bearing 3 and the bearing sleeve 4, the anti-wrinkle die 2 can be kept fixed on one side of the bending die 1 without affecting the rotation of the bending die 1.

[0022] Furthermore, one side of the connecting rod 10 is fitted into the slot on one side of the mounting plate 9, and the connecting rod 10 is fixedly connected by a stop key 11 and a T-key 12. Through the setting of the stop key 11 and the T-key 12, the connection between the stop key 11 and the connecting rod 10 can limit the anti-wrinkle mold 2, and at the same time, the T-key 12 can slide at one end of the slide groove 15 to push the connecting rod 10.

[0023] Furthermore, the T-key 12 forms a sliding structure with the fixed block 16 through the slide groove 15, the first threaded hole 13 on the surface of the T-key 12 is connected to the stop key 11 through a fixing bolt, and the T-key 12 and the fixed block 16 are locked synchronously.

[0024] Working principle: First, install the bearing sleeve 4 on the upper and lower sides of the bending die 1 through the bearing 3, and at the same time, fit the anti-wrinkle die 2 on the side of the bending die 1. Then, connect the bending die 1 to the die base of the pipe bending equipment through the positioning key 8. Then, install the fixing plate 14 on the corresponding position of the pipe bending equipment through the fixing block 16. Then, push the anti-rotation key 11 so that the connecting rod 10 can fit into the slot on one side of the mounting plate 9. Then, penetrate the fixing bolt on the surface of the anti-rotation key 11, and make the fixing bolt pass through the first threaded hole 13 and the T The T-key 12 is locked, and at the same time, the T-key 12 and the fixed plate 14 are locked, and then the bending is completed by rotating the bending die 1. When the bending die 1 rotates with the bending arm, the anti-wrinkle die 2 can still remain motionless and tightly adhere to the inner side of the tube wall. Finally, when the mold needs to be replaced, just insert the locating pin 7 and remove the stop key 11 to remove the mold, and the bending die 1 and the anti-wrinkle die 2 remain stationary with each other. When the mold is used again, there is no need to readjust the fit between the bending die 1 and the anti-wrinkle die 2.
