Description

Technical Field

[0001] This utility model relates to the field of pipe bending support technology, specifically a core-threading mechanism inside a pipe bending machine. Background Technology

[0002] Because the bent pipe is a hollow pipe, the bending area is prone to thinning and flattening under the force during bending, especially for some large-diameter bent pipe products. Flattening of the bending area will lead to the product's flattening rate not meeting the standard, affecting the flow rate of the finished bent pipe. Therefore, internal support is needed to protect the bending area. Refer to announcement number CN221620461U, which describes a core-threading mechanism and a pipe bending machine, especially in the field of pipe bending equipment. The core-threading mechanism of the pipe bending machine includes a frame, a magnetic core-threading assembly, and a power assembly. The magnetic core-threading assembly includes a magnetic sleeve and a core-threading component. The magnetic sleeve is slidably disposed on the frame. The core-threading component includes a core-threading magnet, a connecting rod, and a flexible internal support component connected sequentially along the axis of the magnetic sleeve.

[0003] Although the above-mentioned device can provide internal support, there are various common pipe diameters. Since the device cannot quickly replace the internal support component with one of the appropriate diameter according to the pipe diameter, the efficiency of the internal support will be reduced. Utility Model Content

[0004] The purpose of this utility model is to provide a core-threading mechanism inside a pipe bending machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A core-passing mechanism for a pipe bending machine includes an adjustment seat installed on the rear surface of the main body of the pipe bending machine, and a vertical plate is fixedly connected to the upper surface of the adjustment seat.

[0007] An inner support mechanism is embedded and movably connected to the front surface of the upright plate. The inner support mechanism includes a mounting plate, an inner support tube, and a connecting hole. The mounting plate is slidably connected to the front surface of the upright plate. There are several inner support tubes, which are embedded and movably connected to the side surface of the mounting plate. The connecting hole is opened on the other side surface of the inner support tube, and the inside of the connecting hole is threaded.

[0008] Furthermore, the front surface of the upright plate is provided with a sliding groove, and a connecting plate is slidably connected inside the sliding groove. A connecting seat is fixedly connected to the rear surface of the upright plate, and a hydraulic push rod is fixedly connected inside the connecting seat. The output end of the hydraulic push rod is fixedly connected to the connecting plate.

[0009] Furthermore, the front surface of the upright plate is fixedly connected to a slide rail, a slide plate is slidably connected inside the slide rail, and a threaded connecting rod is rotatably connected inside the slide plate.

[0010] Furthermore, the threaded connecting rod is threadedly connected to the connecting hole and the inner support pipe, and the connecting plate and the sliding plate are fixedly connected.

[0011] Furthermore, the front surface of the adjusting seat is fixedly connected to two guide rods, and the rear surface of the pipe bending machine body is rotatably connected to a first lead screw located between the two guide rods.

[0012] Furthermore, the guide rod is slidably connected to the main body of the pipe bending machine, and the first lead screw is threadedly connected to the adjusting seat.

[0013] Furthermore, a second lead screw is rotatably connected to the inner surface of the upright plate, a handwheel is fixedly connected to the upper end of the second lead screw, and the second lead screw is threadedly connected to the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The slide plate slides along the slide rail. The threaded connecting rod is threadedly engaged with the inner support pipe. Therefore, when the slide plate moves, it can move the inner support pipe in conjunction with the threaded connecting rod. The extension length of the inner support pipe can be adjusted so that the inner support pipe can be inserted into or removed from the curved pipe. The threaded connecting rod and the inner support pipe can be separated by manually rotating the threaded connecting rod, which facilitates the connection of the threaded connecting rod with other types of inner support pipes and improves the compatibility of the device.

[0016] 2. By cooperating with the two guide rods and the first lead screw, the position of the adjusting seat can be quickly adjusted, thereby changing the front and rear position of the inner support mechanism relative to the main body of the pipe bending machine. Turning the handwheel drives the second lead screw to rotate. Since the second lead screw is threadedly connected to the mounting plate, the mounting plate will move linearly along the inner surface of the vertical plate, thereby driving the entire inner support mechanism to move synchronously, realizing the rapid adjustment of the position of the inner support tube. This facilitates the accurate connection of the inner support tube to the threaded connecting rod, improving the conversion efficiency of the pipe bending machine between different pipe bending tasks.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the utility model, a core-piercing mechanism for a pipe bending machine includes an adjustment seat 2 installed on the rear surface of the main body 1 of the pipe bending machine, and a vertical plate 3 is fixedly connected to the upper surface of the adjustment seat 2.

[0024] An inner support mechanism 5 is movably connected to the front surface of the upright plate 3. The inner support mechanism 5 includes a mounting plate 501, an inner support tube 502, and a connecting hole 503. The mounting plate 501 is slidably connected to the front surface of the upright plate 3. There are several inner support tubes 502, which are movably connected to the side surface of the mounting plate 501. The connecting hole 503 is opened on the other side surface of the inner support tube 502, and the inside of the connecting hole 503 is threaded.

[0025] Specifically, the adjusting seat 2 is used to connect the upright plate 3 and the main body 1 of the pipe bending machine. The inner support mechanism 5 extends into the inside of the pipe through the inner support tube 502 to support the inside of the pipe and prevent the pipe from being damaged during bending. There are multiple inner support tubes 502 with different diameters, which can be selected according to the diameter of the pipe to achieve quick switching of the inner support tubes 502.

[0026] Example 1

[0027] like Figure 1-4 As shown, a groove 301 is provided on the front surface of the upright plate 3, and a connecting plate 302 is slidably connected inside the groove 301. A connecting seat 304 is fixedly connected to the rear surface of the upright plate 3, and a hydraulic push rod 303 is fixedly connected inside the connecting seat 304. The output end of the hydraulic push rod 303 is fixedly connected to the connecting plate 302.

[0028] In this embodiment, the hydraulic push rod 303 drives the connecting plate 302 to slide along the slide groove 301, thereby moving the slide plate 401 and realizing the position adjustment of the position threaded connecting rod 402.

[0029] like Figure 1-4 As shown, a slide rail 4 is fixedly connected to the front surface of the upright plate 3. A slide plate 401 is slidably connected inside the slide rail 4. A threaded connecting rod 402 is rotatably connected inside the slide plate 401. The threaded connecting rod 402 is threadedly connected to the connecting hole 503 and the inner support tube 502. The connecting plate 302 and the slide plate 401 are fixedly connected.

[0030] In this embodiment, the slide plate 401 slides along the slide rail 4, and the threaded connecting rod 402 is threadedly engaged with the inner support tube 502. Therefore, when the slide plate 401 moves, it can move the inner support tube 502 in conjunction with the threaded connecting rod 402, adjusting the extension length of the inner support tube 502 so that the inner support tube 502 can extend into or out of the curved pipe. Furthermore, by manually rotating the threaded connecting rod 402, the threaded connecting rod 402 and the inner support tube 502 can be separated, facilitating the connection of the threaded connecting rod 402 with other types of inner support tubes 502 and improving the adaptability of the device.

[0031] Example 2

[0032] Based on Embodiment 1, in order to overcome the problem of inconvenience in switching the inner support tube 502 in Embodiment 1.

[0033] like Figure 1-4 As shown, two guide rods 201 are fixedly connected to the front surface of the adjusting seat 2, and a first lead screw 202 is rotatably connected between the two guide rods 201 on the rear surface of the pipe bending machine body 1. The guide rods 201 and the pipe bending machine body 1 are slidably connected, and the first lead screw 202 is threadedly connected to the adjusting seat 2.

[0034] In this embodiment, the position of the adjusting seat 2 can be quickly adjusted by the cooperation of the two guide rods 201 and the first lead screw 202, thereby changing the front and rear position of the inner support mechanism 5 relative to the main body 1 of the pipe bending machine.

[0035] like Figure 1-4 As shown, a second lead screw 6 is rotatably connected to the inner surface of the upright plate 3, and a handwheel 601 is fixedly connected to the upper end of the second lead screw 6. The second lead screw 6 and the mounting plate 501 are threaded together.

[0036] In this embodiment, rotating the handwheel 601 drives the second lead screw 6 to rotate. Since the second lead screw 6 is threadedly connected to the mounting plate 501, the mounting plate 501 will move linearly along the inner surface of the vertical plate 3, thereby driving the entire inner support mechanism 5 to move synchronously, realizing the rapid adjustment of the position of the inner support tube 502, facilitating the accurate connection of the inner support tube 502 to the threaded connecting rod 402, and improving the conversion efficiency of the pipe bending machine between different pipe bending tasks.
