Description

Technical Field

[0001] The utility model belongs to the technical field of pipe benders, and particularly relates to a pipe bender for processing basketball stands. Background Art

[0002] Basketball is widely popularized globally, which makes the market demand for basketball stands continue to grow. In the process of the continuous development of the basketball stand processing industry, the requirements for the quality and safety of basketball stands are increasing day by day. High-quality basketball stands require good forming quality at the bent parts of pipe fittings to avoid defects such as wrinkles and cracks, so as to ensure the stability and reliability of basketball stands during long-term use. Therefore, a pipe bender is needed to bend the pipe fittings.

[0003] However, during the use of the existing pipe bender for processing basketball stands, operators need to spend a lot of time adjusting the position of the pipe to try to ensure the bending effect of the pipe, which results in an extended processing time for a single bent pipe and reduces production efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pipe bender for processing basketball stands. By setting a positioning mechanism, it solves the problem that during the use of the existing pipe bender for processing basketball stands, operators need to spend a lot of time adjusting the position of the pipe to try to ensure the bending effect of the pipe, which results in an extended processing time for a single bent pipe and reduces production efficiency.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a pipe bender for processing basketball stands, including a support table, on which a positioning mechanism and a pipe bending mechanism are arranged;

[0007] Above the support table is arranged a pipe, above the support table is arranged a first pipe bending plate, above the support table is arranged a second pipe bending plate. The positioning mechanism includes two L-shaped connecting plates I fixedly connected to the outer wall on the left side of the first pipe bending plate. On the right side of each of the two L-shaped connecting plates I is fixedly connected a first support frame. On the inner wall on the right side of the second pipe bending plate are fixedly connected two L-shaped support plates II. The pipe bending mechanism includes two rectangular support plates fixedly connected to the top of the support table.

[0008] Furthermore, on the left side of each of the two L-shaped support plates II is hingedly arranged a connecting plate. On the left side of each of the two connecting plates is fixedly connected a second support frame. On the inner walls of the two second support frames and the two first support frames are rotatably connected rotating shafts. On the outer walls of several rotating shafts are fixedly connected positioning rollers, and several positioning rollers are all in contact with the outer wall of the pipe.

[0009] Furthermore, connection blocks are fixedly connected to both of the two L-shaped support plates II and the two connection plates. Discs are articulated on several of the connection blocks. Two telescopic rods are fixedly connected between several of the discs. Return springs are sleeved on the outer walls of the two telescopic rods. The left sides of the two return springs are fixedly connected to the two discs on the left side respectively, and the right sides of the two return springs are fixedly connected to the two discs on the right side respectively.

[0010] Furthermore, a bidirectional threaded rod is rotatably connected between the two rectangular support plates. The left side of the bidirectional threaded rod penetrates through the rectangular support plate on the left side. Two moving plates are threadedly connected to the outer wall of the bidirectional threaded rod.

[0011] Furthermore, a slide rod is fixedly connected between the two rectangular support plates. The slide rod penetrates through the two moving plates, and the slide rod is slidably connected to the two moving plates. L-shaped connection plates III are fixedly connected to the tops of the two moving plates. The right side of the L-shaped connection plate III on the left side is fixedly connected to the elbow plate I, and the left side of the L-shaped connection plate III on the right side is fixedly connected to the elbow plate II. A motor is fixedly connected to the right side of the rectangular support plate on the right side. The output shaft of the motor is fixedly connected to the bidirectional threaded rod through a coupling.

[0012] The utility model has the following beneficial effects:

[0013] 1. By setting the positioning mechanism, before bending the pipe, the pipe can be placed between several positioning rollers first. The several positioning rollers will position the pipe at a fixed position. When the elbow plate I and the elbow plate II approach each other, the two connection plates will move away from each other under the action of this extrusion force. At this time, the two telescopic rods and the return springs will be stretched under the connection of the connection blocks and the discs. When the return springs are stretched, they will undergo elastic deformation and generate corresponding pulling forces. After the pipe is bent, start the motor again to make it reverse, driving the elbow plate I and the elbow plate II to move away from each other. At this time, the two connection plates will be reset under the pulling force of the return springs, ensuring that the position of the pipe is accurate during the bending process, guaranteeing the accuracy and consistency of the bent pipe, being beneficial to improving the quality of the bent pipe, reducing the rejection rate, avoiding excessive extrusion force directly acting on the pipe and the equipment during the bending process, preventing the pipe from being damaged due to excessive force, protecting the relevant components of the bending equipment at the same time, extending the service life of the equipment, and enabling the equipment to quickly return to the initial state, facilitating the next bending operation, improving the working efficiency, and reducing the time of manual intervention and adjustment;

[0014] 2. By setting up the elbow pipe mechanism, when it is necessary to bend the pipe, the motor can be started. The motor will drive the bidirectional threaded rod to rotate. At this time, the three L-shaped connecting plates will approach each other under the restriction of the sliding rod. Thus, the first elbow pipe plate and the second elbow pipe plate will be driven by the three L-shaped connecting plates to approach each other. And grooves are provided on the sides where the first elbow pipe plate and the second elbow pipe plate approach each other, and the grooves are adapted to the pipe. Therefore, when the first elbow pipe plate and the second elbow pipe plate approach each other, the pipe will be bent. The grooves on the first elbow pipe plate and the second elbow pipe plate can better fit the pipe, apply pressure evenly during the bending process, avoid problems such as deformation and rupture of the pipe due to excessive local stress, and at the same time ensure that the shape of the elbow pipe meets the requirements. The whole operation process is relatively simple, reducing the complexity and labor intensity of manual operation and improving work efficiency.

[0015] Of course, it is not necessary for any product implementing the present utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
