Description

Technical Field

[0001] This utility model relates to the field of tube expansion technology, and in particular to a multi-station vertical tube expander. Background Technology

[0002] The tube expansion process is a key step in achieving a tight connection between the tube and the tube sheet. Through tube expansion, the metal tube (such as copper, aluminum, or stainless steel tube) undergoes plastic deformation under axial pressure, uniformly conforming to the tube sheet hole wall, thereby achieving the purpose of sealing and fixing.

[0003] Existing multi-station vertical tube expanders typically involve manually clamping the tube sheet containing the tube fitting onto the expander's fixture, and then using the expander rod on the expander to press down and expand the tube. However, the manual operation of clamping and releasing the fixture and removing the tube during the loading and unloading process increases labor costs, makes it impossible to achieve fast automatic clamping and unloading, affects work efficiency, and is quite inconvenient.

[0004] Therefore, it is necessary to design a multi-station vertical tube expander that can automatically clamp the tube during pressure expansion and automatically unload the tube when switching stations, thereby improving work efficiency. Utility Model Content

[0005] To overcome the shortcomings of existing multi-station vertical tube expanders, which require manual operation to clamp and release the clamps during loading and unloading, thus increasing labor costs and failing to achieve rapid automatic clamping and unloading, thereby affecting work efficiency, this utility model provides a multi-station vertical tube expander that can automatically clamp during tube expansion and automatically unload when switching stations, thereby improving work efficiency.

[0006] Technical Solution: A multi-station vertical tube expander includes a support frame, a motor, a rotary table, a tube expander assembly, pulleys, mounting frames, clamping frames, guide plates, telescopic springs, and an opening and closing assembly. The motor is connected to the lower front of the support frame, and the motor and processor are electrically connected via a control module. The output shaft of the motor is connected to the rotary table. A tube expander assembly capable of expanding tubes is located at the upper rear of the support frame. The tube expander assembly has two rotating pulleys on the left and right sides. Multiple mounting frames are connected to the rotary table. Each mounting frame has two sliding guide plates. Clamping frames are connected to the sides of the guide plates that are close to each other. Two telescopic springs connect each guide plate to the adjacent mounting frame. An opening and closing assembly capable of automatically unloading materials when switching stations is located at the bottom of each mounting frame.

[0007] In one embodiment, the upper part of the guide plate has an inclined structure.

[0008] In one embodiment, the clamping frame has a V-shaped structure.

[0009] In one embodiment, the rotary table has multiple feeding ports.

[0010] In one embodiment, the tube expansion assembly includes an electric actuator, a sliding frame, and an expansion rod. The electric actuator is connected to the upper rear part of the support frame. The electric actuator and the processor are electrically connected through a control module. The telescopic rod of the electric actuator is connected to the sliding frame. The sliding frame is slidably connected to the support frame. The expansion rod is connected to the middle of the sliding frame. All pulleys are rotatably connected to the sliding frame.

[0011] In one embodiment, the opening and closing assembly includes a rotating plate, gears, a torsion spring, and a toothed arc ring. The lower part of the mounting frame is rotatably connected to the rotating plate, and gears are connected to the outer side of the rotating plate. The lower left part of the support frame is connected to the toothed arc ring, which meshes with its adjacent gear. The rotating plate is connected to the adjacent mounting frame with a torsion spring.

[0012] Beneficial effects: 1. When the sliding frame moves downward, the pulley will squeeze the guide plate, which will drive the clamping frame to move inward to automatically clamp the tube plate containing the pipe fitting. When the rotary table rotates, the gear meshes with the toothed arc ring, which drives the rotary plate to rotate and the discharge port opens, allowing the pipe fitting to fall downward. This achieves the effect of automatically clamping when the tube is pressed and expanded, and automatically discharging when switching work stations, thus improving work efficiency.

[0013] 2. This utility model uses a motor to drive a rotary table to rotate, allowing for quick switching between workstations containing pipe fittings, thereby improving processing efficiency. Attached Figure Description

Detailed Implementation

[0020] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0021] A multi-station vertical tube expander, such as Figures 1-5 As shown, the assembly includes a support frame 1, a motor 2, a rotary table 3, an expansion tube assembly, pulleys 7, mounting brackets 8, clamping brackets 9, guide plates 10, telescopic springs 11, and an opening and closing assembly. The motor 2 is connected to the lower front of the support frame 1. The motor 2 and the processor are electrically connected through a control module. The output shaft of the motor 2 is connected to the rotary table 3. The rotary table 3 has four feeding ports for easy feeding. The expansion tube assembly is located at the upper rear of the support frame 1. The expansion tube assembly has two left and right pulleys 7 rotating on it. Four mounting brackets 8 are connected to the rotary table 3. Each mounting bracket 8 has two guide plates 10 slidably connected to it. Each guide plate 10 has a clamping bracket 9 connected to one side of the guide plates 10 that are close to each other. The clamping bracket 9 has a V-shaped structure. The upper part of the guide plate 10 has an inclined structure to facilitate the pulleys 7 pressing the guide plate 10 to move it. Each guide plate 10 is connected to an adjacent mounting bracket 8 with two telescopic springs 11. Each mounting bracket 8 has an opening and closing assembly at its lower part.

[0022] like Figures 1-3 As shown, the tube expansion assembly includes an electric push rod 4, a sliding frame 5, and an expansion rod 6. The electric push rod 4 is connected to the upper rear part of the support frame 1. The electric push rod 4 and the processor are electrically connected through a control module. The telescopic rod of the electric push rod 4 is connected to the sliding frame 5. The sliding frame 5 is slidably connected to the support frame 1. The expansion rod 6 is connected to the middle of the sliding frame 5. The pulleys 7 are all rotatably connected to the sliding frame 5.

[0023] like Figure 2 and Figure 4 As shown, the opening and closing assembly includes a rotating plate 12, a gear 13, a torsion spring 14, and a toothed arc ring 15. The lower part of the mounting frame 8 is rotatably connected to the rotating plate 12, and the outer side of the rotating plate 12 is connected to the gear 13. The lower left part of the support frame 1 is connected to the toothed arc ring 15, and the toothed arc ring 15 meshes with its adjacent gear 13. The rotating plate 12 is connected to the adjacent mounting frame 8 by a torsion spring 14.

[0024] When using this utility model, first place the support frame 1 in the pipe processing area, then place the pipe plate containing the pipe between the clamping frames 9, then start the electric push rod 4 to drive the sliding frame 5 and the expansion rod 6 to move downward. After the sliding frame 5 moves downward to a certain distance, the pulley 7 will squeeze the guide plate 10, causing the guide plate 10 to move inward on the mounting frame 8. The telescopic spring 11 contracts, causing the clamping frame 9 to move inward to automatically clamp the pipe plate containing the pipe. At the same time, the expansion rod 6 expands the pipe, causing the pipe to undergo plastic deformation under axial pressure and evenly fit the hole wall of the pipe plate. After the pipe is processed, the electric push rod 4 drives the sliding frame 5 to move upward, causing the expansion rod 6 to be removed from the pipe. At the same time, the guide plate 10 is no longer squeezed, the telescopic spring 11 returns to its original state, and the clamping frame 9 moves outward to release the pipe plate. Then start the motor 2 to drive the rotary table 3 to rotate, switching the workstation where the pipe is placed, thereby enabling quick switching of workstations and improving processing efficiency. When the rotary table 3 rotates to a certain horizontal angle, the gear 13 on the mounting bracket 8, which holds the processed pipe fittings, meshes with the toothed arc ring 15, causing the rotary plate 12 to rotate. The torsion spring 14 deforms, aligning the discharge port on the rotary plate 12 with the discharge port on the rotary table 3, allowing the pipe fittings to fall downwards through the rotary table 3. This enables automatic clamping during the downward expansion of the pipe and automatic unloading during station switching, improving work efficiency. When the gear 13 no longer meshes with the toothed arc ring 15, the torsion spring 14 returns to its original state, causing the rotary plate 12 to rotate and reset.
