Description

Technical Field

[0001] This utility model relates to the field of pipe bending equipment, specifically to an auxiliary device for pipe bending machine fitting processing. Background Technology

[0002] Nowadays, industries such as automobile manufacturing, aerospace, petrochemicals, and construction installation all require bending pipes to specific angles and shapes, which necessitates a variety of pipe bending machines. Pipe bending machines can be divided into manual control pipe bending machines, semi-automatic control pipe bending machines, and fully automatic pipe bending machines. Among them, semi-automatic control pipe bending machines improve production efficiency compared to manual control pipe bending machines and have lower machine costs compared to fully automatic control pipe bending machines. Therefore, many small and medium-sized factories choose semi-automatic control pipe bending machines.

[0003] Semi-automatic pipe bending machines require manual adjustment of the required bending angle and loading of the pipe. The machine can then automatically transport the pipe for clamping, bending, and other processes.

[0004] The semi-automatic pipe bending machine requires the pipe to be placed on the feeding tray and rolled naturally onto the conveying channel, where it is pushed forward by the push rod. However, it is difficult to add a mandrel in this way. After the pipe is processed, wrinkles are easily formed at the bend, and the clamping device may also clamp too tightly, causing the pipe to deform, resulting in a low compliance rate. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an auxiliary device for pipe bending machine to solve the technical problem that it is not easy to add a mandrel in a semi-automatic pipe bending machine.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for pipe bending machine processing, comprising a base and a support frame, a pipe bending assembly installed on one side of the base, a pipe bending module movably installed on one side of the base, a tray installed above the support frame, and pipe fittings placed in the tray, a sliding groove opened on one side of the base, and a pushing assembly installed inside the sliding groove, a telescopic assembly installed at one end of the pushing assembly, and an arc plate installed on one side of the base.

[0007] By adopting the above technical solution, the problem of not being able to easily insert the mandrel into the semi-automatic pipe bending machine is solved. When the pipe slides into the arc plate through the tray, the telescopic component is activated to insert the mandrel into the pipe. The pushing component pushes the pipe forward, so that the pipe and the mandrel enter the bending component to perform the bending operation. After the bending is completed, the pushing component drives the telescopic component back to the initial position, which facilitates the next bending of the pipe.

[0008] The present invention is further configured such that the pipe bending assembly includes a support seat installed on the top of the base, and a fixing block is installed on one side of the support seat, and a rotating block is movably installed on one side of the base.

[0009] By adopting the above technical solution, a motor can be installed inside the fixed block to control the movement of the bending limit block, and the rotating block can push the pipe to bend.

[0010] The present invention is further configured such that the pushing component includes a reciprocating lead screw installed inside the slide groove, and a sliding ring is sleeved on the outer wall of the reciprocating lead screw, and a push block is fixedly connected to one side of the sliding ring.

[0011] By adopting the above technical solution, the reciprocating screw rotation can drive the sliding ring to move back and forth, so that the push block moves synchronously. The push block pushes the push rod to continue moving forward, so that the pipe can reach the pipe bending assembly for pipe bending operation.

[0012] The present invention is further configured such that the telescopic component includes a push rod installed on one side of the push block, and a connecting rod is installed at one end of the push rod, and a core rod is movably installed at one end of the connecting rod.

[0013] By adopting the above technical solution, the pusher can push the push rod forward, allowing the mandrel at the end to be inside the pipe and bend together. The push rod can control the extension and retraction of the connecting rod, and after the bending operation is completed, the mandrel can be pulled back to the initial position to prepare for the next bending operation.

[0014] The present invention is further configured such that the end of the support frame away from the base is higher than the other end, and the tray is installed at an angle above the support frame.

[0015] By adopting the above technical solution, the tilting of the tray can facilitate the rolling of the pipes to a lower position, and finally they fall into the curved plate.

[0016] The present invention is further configured such that the arc-shaped plate is in the shape of an arc below the connecting rod, and baffles are provided on both sides of the arc-shaped plate.

[0017] By adopting the above technical solution, the arc-shaped position of the arc plate can limit the pipe fitting here, making it convenient for the telescopic component to move forward. The baffles on both sides of the arc plate can prevent the pipe fitting from rolling off.

[0018] The present invention is further configured such that the connecting rod can be retracted into the push rod, the bottom of the push rod is flat, and the bottom of the push rod is higher than the highest point of the arc plate.

[0019] By adopting the above technical solution, the push rod can continue to push the connecting rod forward above the arc plate. When the connecting rod retracts to the top of the push rod, the mandrel will not affect the tube rolling into the arc plate.

[0020] In summary, the present invention has the following main advantages:

[0021] This utility model, equipped with a support frame, tray, arc plate, telescopic component, and pushing component, solves the problem of difficulty in inserting mandrels in semi-automatic pipe bending machines. When the pipe slides into the arc plate through the tray, the telescopic component is activated to insert the mandrel into the pipe. The pushing component then pushes the pipe forward, allowing the pipe and mandrel to enter the bending component for bending. After bending is completed, the pushing component drives the telescopic component back to its initial position, facilitating the next bending of the pipe. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] An auxiliary device for pipe bending machine pipe fitting processing, such as Figure 1 - Figure 5 As shown, it includes a base 1 and a support frame 4, with a bent pipe assembly 2 installed on one side of the base 1.

[0031] Specifically, a pipe bending module 3 is movably installed on one side of the base 1, and a tray 41 is installed above the support frame 4, with a pipe fitting 5 placed inside the tray 41. The pipe fitting 5 is placed on the tray 41, and an arc plate 6 is installed on one side of the base 1. As the tray 41 tilts, the pipe fitting 5 slides into the arc plate 6. A sliding groove 101 is opened on one side of the base 1, and a pushing component 8 is installed inside the sliding groove 101. When the pushing component 8 starts to work, the reciprocating screw 83 rotates, the sliding ring 82 slides forward, and drives the push block 81 to move forward. A telescopic component 7 is installed at one end of the pushing component 8, so that the push rod 71 pushes the connecting rod 72 and the core rod 73 forward. The push rod 71 also pushes the pipe fitting 5 forward until the pipe fitting 5 enters the pipe bending component 2 and begins to bend.

[0032] Please see Figure 1 The pipe bending assembly 2 includes a support base 21 installed on the top of the base 1, and a fixing block 22 is installed on one side of the support base 21. A rotating block 23 is movably installed on one side of the base 1. A motor can be installed inside the fixing block 22 to control the movement of the pipe bending limit block. The rotating block 23 can push the pipe 5 to bend.

[0033] Please see Figure 3 and Figure 4 The pushing component 8 includes a reciprocating screw 83 installed inside the slide groove 101, and a sliding ring 82 is sleeved on the outer wall of the reciprocating screw 83. A push block 81 is fixedly connected to one side of the sliding ring 82. The rotation of the reciprocating screw 83 can drive the sliding ring 82 to move back and forth, so that the push block 81 moves synchronously. The push block 81 pushes the push rod 71 to continue to move forward, so that the pipe fitting 5 can reach the pipe bending component 2 for pipe bending operation.

[0034] Please see Figure 1 - Figure 5 The telescopic assembly 7 includes a push rod 71 installed on one side of the push block 81, and a connecting rod 72 is installed at one end of the push rod 71. A mandrel 73 is movably installed at one end of the connecting rod 72. The push block 81 pushes the push rod 71 forward so that the mandrel 73 at the end can be inside the pipe fitting 5 and bend the pipe together. The push rod 71 can control the extension and retraction of the connecting rod 72. After the pipe bending operation is completed, the mandrel 73 can be pulled back to the initial position to prepare for the next pipe bending operation.

[0035] Please see Figure 1 and Figure 2 The end of the support frame 4 that is away from the base 1 is higher than the other end. The tray 41 is installed at an angle above the support frame 4. The tilt of the tray 41 makes it easier for the pipe 5 to roll down and eventually fall into the arc plate 6.

[0036] Please see Figure 2 - Figure 5The arc plate 6 is in the shape of an arc below the connecting rod 72, and baffles are provided on both sides of the arc plate 6. The arc position of the arc plate 6 can limit the pipe 5 here, making it convenient for the telescopic component 7 to be pushed forward. The baffles on both sides of the arc plate 6 can prevent the pipe 5 from rolling off.

[0037] Please see Figure 4 and Figure 5 The connecting rod 72 can retract into the push rod 71. The bottom of the push rod 71 is flat and the bottom of the push rod 71 is higher than the highest point of the arc plate 6. The push rod 71 can continue to push the connecting rod 72 forward above the arc plate 6. When the connecting rod 72 retracts to the top of the push rod 71, the mandrel 73 will not affect the pipe 5 rolling into the arc plate 6.

[0038] The working principle of this utility model is as follows: When it is necessary to bend the pipe fitting 5, the pipe fitting 5 is placed on the tray 41. As the tray 41 tilts, the pipe fitting 5 will slide into the arc plate 6. The arc position of the arc plate 6 limits the pipe fitting 5 here. At this time, the connecting rod 72 in the telescopic assembly 7 retracts into the push rod 71, and the mandrel 73 is outside the tray 41. When the pipe fitting 5 falls into the arc plate 6, the connecting rod 72 pushes the mandrel 73 to insert into the pipe fitting 5, and the push assembly 8 starts to work. The reciprocating screw 83 rotates, the sliding ring 82 slides forward, and drives the push block 81 to move forward. Thus, the push rod 71 pushes the connecting rod 72 and the mandrel 73 forward. The push rod 71 also pushes the pipe fitting 5 forward until the pipe fitting 5 enters the bending assembly 2 and begins to bend.

[0039] When a pipe fitting 5 finishes bending, the reciprocating screw 83 rotates in the opposite direction, causing the sliding ring 82 and push block 81 to slide backward, thereby moving the telescopic assembly 7 backward. Another set of pipe fittings 5 ​​will slide onto the arc plate 6 as the tray 41 tilts. Since the mandrel 73 is outside the push rod 71, but since the mandrel 73 is composed of round beads, the pipe fitting 5 can fall smoothly into the arc plate 6. This process is repeated to bend the next set of pipe fittings 5.
