Description

Technical Field

[0001] The invention relates to the technical field of bending equipment, in particular to a steel pipe bending training platform. Background Art

[0002] In mechanical manufacturing, especially the manufacturing of steel pipes is very common. In many cases, steel pipes need to be bent. Steel pipe bending machines are used to bend stainless steel and other non-ferrous metal thin-walled garden pipes, square pipes, and rectangular pipes. Bend them into any arc as needed. When using this machine to bend pipes, steel pipes of different shapes can be cold-bent according to different needs. General bending machines are manual bending machines. Due to the good rigidity of steel pipes, it is not easy to bend them by manual bending machines. It takes a lot of effort and time to bend them. In practical applications, it is often necessary to perform three-dimensional bending processing of steel pipes at multiple angles and positions. Three-dimensional bending steel pipes are mainly used for the production of bicycle, electric vehicle, and motorcycle handlebars. Because this type of component is particularly large in quantity, manufacturers need an efficient and labor-saving machine to complete it. The existing bending machines are inconvenient to use, the processing efficiency is not high, and the production cost and energy consumption are also high.

[0003] In current university teaching, students majoring in machinery need to perform practical operations during the learning process. However, the existing bending machines have complex structures and large overall equipment, which is not conducive to students' practical training. Summary of the invention

[0004] The purpose of the present invention is to provide a steel pipe bending training platform to solve the problems of low efficiency, inconvenient processing, and disadvantages for students' training of existing bending machines.

[0005] In order to achieve the above-mentioned technical objectives and the above-mentioned technical effects, the present invention discloses a steel pipe bending training platform, which includes a frame, a reciprocating mechanism and two bending modules respectively arranged at both ends of the frame, the bending module includes a movable part, a fixed part and a clamping part, the movable part and the clamping part are arranged on the reciprocating mechanism, and the fixed part is arranged on the frame.

[0006] Furthermore, the fixed part is two auxiliary rollers movably arranged on the frame, and the movable part is two active rollers movably arranged on the reciprocating mechanism.

[0007] Furthermore, the two active rollers are respectively located on the inner side or the outer side of the two auxiliary rollers.

[0008] Furthermore, grooves are provided on the roller surfaces of the active roller and the auxiliary roller.

[0009] Furthermore, the clamping part is arranged at the front end of the movable part, and the clamping part includes a support plate, an eccentric wheel and a return spring. The support plate is slidably arranged on the reciprocating mechanism, one end of the return spring is connected to the support plate, and the other end of the return spring is connected to the reciprocating mechanism, and the eccentric wheel is in conflict with the side of the support plate away from the fixed part.

[0010] Furthermore, the bending module also includes a limit block arranged on the side of the movable part.

[0011] Furthermore, the bending module also includes limiting plates arranged on two sides of the movable part, and the limiting plates are rotatably connected to the reciprocating mechanism.

[0012] Furthermore, a control electric box is arranged on the side of the frame, and the control electric box is electrically connected to the reciprocating mechanism.

[0013] Furthermore, a proximity switch is provided on the frame at a position close to the bending module, and the proximity switch is electrically connected to the control electrical box.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention fixes the local position of the steel pipe by the fixed part of the bending module, and the reciprocating mechanism drives the movement of the active part of the bending module to bend the steel pipe. The bending modules are arranged at both ends of the frame, so that when the reciprocating mechanism reciprocates on the frame, the two ends can be bent at the same time.

[0016] 2. The difference in the relative inner and outer sides of the active roller and the auxiliary roller of the bending module can realize the bending of the steel pipe. When the steel pipe needs to be bent twice at different angles, the distance between the active rollers and the auxiliary rollers of the two bending modules can be adjusted. One bending module performs the first processing on the steel pipe, and the other bending module performs the second processing on the steel pipe. In this way, the present invention can realize the double processing of the steel pipe.

[0017] 3. The grooves on the roller surfaces of the active roller and the auxiliary roller are used to clamp the steel pipe. The clamping part is used to manually clamp and fix the non-bending part of the steel pipe to prevent bending of the non-bending part. The proximity switch is used to detect the displacement of the reciprocating mechanism. When the active part of the bending module bends the steel pipe to a certain angle, the proximity switch detects the displacement of the reciprocating mechanism and sends a signal to the control box to control the reversal of the reciprocating mechanism stroke.

[0018] 4. The present invention has low operating requirements for operators, is not prone to operating errors, has a low scrap rate, low production costs, low labor intensity, and is convenient for students' practical training operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments.

[0027] like Figures 1 to 5 As shown, the present invention discloses a steel pipe bending training platform, which includes a frame 1, a reciprocating mechanism 2 and a first bending module and a second bending module respectively arranged at two ends of the frame 1, the first bending module and the second bending module each include a movable part 3, a fixed part 4 and a clamping part 5, the movable part 3 and the clamping part 5 are arranged on the reciprocating mechanism 2, the fixed part 4 is arranged on the frame 1, and the reciprocating mechanism 2 performs a linear reciprocating motion on the frame 1.

[0028] The fixed part 4 is two auxiliary rollers movably arranged on the frame 1, the movable part 3 is two active rollers movably arranged on the reciprocating mechanism 2, the two active rollers of the first bending module are respectively located on the inner sides of the two auxiliary rollers, and the two active rollers of the second bending module are respectively located on the outer sides of the two auxiliary rollers. The relative positions and spacings of the active rollers of the first bending module and the second bending module are set differently. One bending machine can process the same steel pipe twice at different positions. The roller surfaces of the active rollers and the auxiliary rollers are provided with clamping grooves 10 for clamping the steel pipes.

[0029] The clamping part 5 is arranged at the front end of the movable part 3, and the clamping part 5 includes a support plate 51, an eccentric wheel 52 and a return spring 53. The support plate 51 is slidably arranged on the reciprocating mechanism 2, one end of the return spring 53 is connected to the support plate 51, and the other end of the return spring 53 is connected to the reciprocating mechanism 2. The eccentric wheel 52 is in conflict with the side of the support plate 51 away from the fixed part 4. The clamping part 5 is used to manually clamp the non-bending part of the steel pipe to prevent the non-bending part from bending.

[0030] The first bending module includes a limit block 7 arranged on the side of the active part 3 of the first bending module, and the second bending module includes a limit plate 6 arranged on both sides of the active part 3 of the second bending module. The limit plate 6 is rotatably connected to the reciprocating mechanism 2. The limit block 7 and the limit plate 6 are both used to limit the steel pipe to be processed. The first bending module is used for the first processing of the steel pipe, and the second bending module is used for the second processing of the steel pipe. When the second processing of the steel pipe needs to be tilted at a certain angle, the limit plate 6 is rotated at a certain angle so that the limit plate 6 and the plane of the reciprocating mechanism 2 are at a certain angle.

[0031] A control box 8 is provided on the side of the frame 1, and the control box 8 is electrically connected to the reciprocating mechanism 2. A proximity switch 9 is provided at a position close to the first bending module and the second bending module on the frame 1, and the proximity switch 9 is electrically connected to the control box 8. The control box 8 is used to control the opening and closing of the entire equipment, and is provided with an emergency stop switch. The proximity switch 9 detects the displacement of the reciprocating mechanism 2 and sends a signal to the control box 8 to reverse the stroke of the reciprocating mechanism 2.

[0032] The use process of the present invention:

[0033] The control box 8 controls the opening and closing of the entire equipment. The reciprocating mechanism 2 reciprocates on the frame 1. When the reciprocating mechanism 2 moves toward one end of the frame 1 where the first bending module is provided, the steel pipe to be bent is placed between the active roller and the auxiliary roller, and the eccentric wheel 52 is rotated. The eccentric wheel 52 contacts the support plate 51 and pushes the support plate 51 to clamp and fix the steel pipe. The active roller of the first bending module moves close to the auxiliary roller, and the portion of the steel pipe between the active roller and the auxiliary roller is bent for the first time. When the proximity switch 9 detects that the reciprocating mechanism 2 has moved to a certain position, a signal is sent to the control box 8. The control box 8 controls the reciprocating mechanism 2 to reverse, rotates the eccentric wheel 52, and moves away from the support plate 51. The reset spring 53 pulls the support plate 51 away from the steel pipe, and the steel pipe that has been bent for the first time is taken out. At this time, the second bending module repeats the steps of the first bending module to perform a second bending on the steel pipe placed on the second bending module.
