Description

Technical Field

[0001] This utility model belongs to the field of pig tail tube processing technology, and specifically relates to a pig tail tube processing bending machine for a converter. Background Technology

[0002] The pig tail tube is an essential component in the converter. This component operates under high temperature and pressure, inevitably leading to thermal expansion and contraction. To prevent cracking due to this, the component must be bent into a specific shape. Previously, the factory lacked bending equipment and had to outsource this task. Later, manual bending equipment was purchased, but this equipment is primarily used for bending thin-walled tubes of ordinary materials. Using it to bend thick-walled stainless steel tubes results in low efficiency and high labor intensity for workers. Utility Model Content

[0003] The purpose of this utility model is to provide a pig tail tube bending machine for converters, which solves the technical problems of low efficiency and high labor intensity of manual bending.

[0004] To solve the above-mentioned technical problems, this utility model provides a pig tail tube bending machine for conversion furnaces, comprising:

[0005] frame;

[0006] The drive mechanism is mounted on the frame;

[0007] The pipe bending die is detachably locked to the output end of the drive mechanism; the pipe bending die is a curved wheel structure with an arc groove.

[0008] Two guide positioning wheels are arranged linearly and detachably rotatably mounted on the frame.

[0009] An arc-shaped positioning block is symmetrically engaged with the arc-shaped groove on the bending mold to form a channel through which the pig tail tube can be fitted and pass, and to apply a clamping force to the pig tail tube.

[0010] Preferably, the driving mechanism includes: a drive motor, a reducer, and a transmission belt; the output end of the drive motor is connected to the input end of the reducer via the transmission belt, and the output end of the reducer is detachably locked to the bending die.

[0011] Preferably, it also includes an L-shaped rod, which is welded to the curved wheel structure to stop and limit the top and side walls of the placed arc-shaped positioning block.

[0012] Preferably, it also includes a sensing limit rod, which includes an annular portion and a straight rod portion; the annular portion and the straight rod portion are integrally formed and connected, and the annular portion is tightly sleeved on the output end of the reducer and located below the curved wheel structure, while the straight rod portion is located directly behind.

[0013] Preferably, the top of the annular portion is stopped and limited by the bottom wall of the placed arc-shaped positioning block.

[0014] Preferably, it also includes an external induction switch for detection adapted to the straight rod section, so as to sense the rotation angle of the bending mold.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] This utility model uses a motor to drive the pipe bending, which saves time and effort compared to manual pipe bending, thereby improving work efficiency and reducing the labor intensity of workers; at the same time, by changing different models of pipe bending molds and arc-shaped positioning blocks, it can process pig tail pipes of different diameters, making it widely applicable.

The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0022] like Figures 1-3 As shown, this utility model embodiment provides a pig tail tube bending machine for a converter, comprising:

[0023] Frame 1; mainly composed of four channel steel legs and a supporting work plate;

[0024] Drive mechanism 2 is mounted on frame 1;

[0025] The pipe bending mold 3 is detachably locked to the output end of the drive mechanism 2; the pipe bending mold 3 is a curved wheel structure with an arc groove; multiple pipe bending molds 3 with different diameters and arc groove models can be manufactured.

[0026] Two guide positioning wheels 4 are arranged and are linearly and detachably rotatably mounted on the frame 1. Multiple guide positioning wheels 4 with different diameter arc groove models can be manufactured.

[0027] The arc-shaped positioning block 5 is symmetrically engaged with the arc-shaped groove on the bending mold 3 to form a channel through which the pig tail tube can be fitted and pass, and to apply a clamping force to the pig tail tube; multiple arc-shaped positioning blocks 5 with different diameter arc-shaped groove models can be prepared.

[0028] The drive mechanism 2 includes a drive motor 21, a reducer 22, and a transmission belt 23; the output end of the drive motor 21 is connected to the input end of the reducer 22 via the transmission belt 23, and the output end of the reducer 22 is detachably locked to the bending die 3.

[0029] It also includes an L-shaped rod 6, which is welded to the curved wheel structure to stop and limit the top and side walls of the placed arc-shaped positioning block 5.

[0030] It also includes a sensing limit rod 7, which includes an annular part and a straight rod part; the annular part and the straight rod part are integrally formed and connected, and the annular part is tightly sleeved on the output end of the reducer 22 and located below the curved wheel structure, while the straight rod part is located directly behind.

[0031] The top of the annular part is stopped and limited by the bottom wall of the placed arc-shaped positioning block 5.

[0032] It also includes an external induction switch, which is adapted to the straight rod section for detection, so as to realize the rotation angle of the bending die 3.

[0033] It also includes the following working principles:

[0034] First, the pig tail tube is passed through the channel that is compatible with the pig tail tube. Then, the arc-shaped positioning block 5 is manually placed tightly against the outer wall of the tube for clamping. Then, the drive motor 21 drives the reducer 22 through the transmission belt 23. The bending mold 3 corresponding to the diameter and bending radius of the pig tail tube is installed on the output shaft of the reducer 22. An arc-shaped positioning block 5 is added to the bending mold 3 to fix the pig tail tube head that needs to be bent. There is a set of two guide positioning wheels 4 corresponding to the diameter of the tube in front of the bending mold 3. The main function is to prevent the tube from scratching the tube wall when the tube moves forward while bending. In addition, it is used to limit the tube and prevent lateral movement. At the same time, through the above-mentioned sensing limit rod 7, the pig tail tube is kept on the same plane when bending the second bend. Moreover, the sensing limit rod 7 detects with the external sensing limit switch to determine the rotation angle of the bending mold 3.
