Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment, specifically a pipe bending machine for automotive parts processing. Background Technology

[0002] Automotive parts generally refer to the various units that make up a car and the products that serve the car. There are many types of automotive parts. As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also been developing rapidly. Some automotive parts require the use of tube bending machines for processing.

[0003] However, current pipe bending machines still have some shortcomings. For example, patent application CN202122565738.0 discloses a CNC pipe bending machine for processing automotive parts. It uses a bending mechanism to bend automotive parts, effectively reducing the manpower consumption when bending manually and facilitating the smooth operation of automotive parts production and processing. However, its pipe fixing function is poor, which makes the pipe easy to move when the bending mechanism is bending the pipe, thus interfering with the bending effect of the bending mechanism and resulting in certain defects in use.

[0004] Therefore, there is an urgent need to improve this shortcoming. This utility model is to study and improve the existing structure to provide a pipe bending machine for processing automotive parts. Utility Model Content

[0005] The purpose of this utility model is to provide a pipe bending machine for processing automotive parts, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pipe bending machine for processing automotive parts, comprising a worktable and a support bracket. An adjustment mechanism is movably mounted on the inner surface of the worktable, and a support mechanism is rotatably connected to the side of the adjustment mechanism. The support bracket is fixedly mounted on the top of the worktable, and a stamping cylinder is mounted on the top of the support bracket. A connecting assembly is fixedly connected to the extension end of the stamping cylinder, and a bending mechanism is movably mounted on the bottom of the connecting assembly. A limit assembly is slidably connected to the top of the worktable. The connecting assembly includes a mounting plate, a positioning groove, a connecting bracket, and a locking mechanism. A positioning groove is symmetrically opened on the bottom of the mounting plate, and a connecting bracket is fixedly mounted on the bottom of the mounting plate. Locking mechanisms are symmetrically mounted on both sides of the connecting bracket.

[0007] Furthermore, the bearing mechanism includes a connecting mechanism, a connecting shaft, a connecting roller, and an annular bearing frame. The connecting mechanism is adapted to be installed on the outer surface of the adjusting mechanism, and the connecting shaft is rotatably connected to the side of the connecting mechanism. The connecting roller is fixedly installed at the end of the connecting shaft, and the annular bearing frame is fixedly connected to the outer surface of the connecting roller.

[0008] Furthermore, the end of the connecting shaft is fixedly connected to the end of the connecting roller, and the other end of the connecting shaft is rotatably connected to the side of the connecting mechanism, and the connecting roller forms a rotating structure with the connecting mechanism through the connecting shaft.

[0009] Furthermore, the locking mechanism includes a locking rod, a connecting plate, a pull ring, an arc-shaped locking block, and a locking spring. The end of the locking rod is fixedly connected to the connecting plate, and the other end of the connecting plate is fixedly installed with a pull ring. The other end of the locking rod is fixedly installed with an arc-shaped locking block, and the end of the connecting plate is fixedly connected with a locking spring.

[0010] Furthermore, the end of the locking spring is fixedly connected to the end of the connecting plate, and the other end of the locking spring is fixedly connected to the outer surface of the connecting bracket, and the connecting plate and the connecting bracket form an elastic structure through the locking spring.

[0011] Furthermore, the bending mechanism includes a bending die, a limiting groove, and a positioning post. The bending die has symmetrically opened limiting grooves on both sides, and the top of the bending die is symmetrically fixedly installed with positioning posts. The positioning posts form a locking structure with the mounting plate through the positioning groove.

[0012] Furthermore, the internal dimensions of the limiting groove perfectly match the external dimensions of the arc-shaped block, and the arc-shaped block forms a locking structure with the bending mold through the limiting groove.

[0013] Furthermore, the limiting component includes a fixed bracket, a T-shaped slide bar, a threaded adjusting rod, a connecting seat, a limiting block, and a limiting guide rod. The T-shaped slide bar is symmetrically fixedly installed at the bottom of the fixed bracket, and the threaded adjusting rod is threadedly connected to the inside of the fixed bracket. The end of the threaded adjusting rod is rotatably connected to the connecting seat, and the limiting block is fixedly installed at the bottom of the connecting seat. The limiting guide rod is symmetrically fixedly installed at the top of the limiting block.

[0014] This utility model provides a pipe bending machine for processing automotive parts, which has the following advantages:

[0015] 1. This utility model, through the setting of a connecting seat and a limiting guide rod, allows the operator to quickly adjust the height of the limiting block when rotating the threaded adjusting rod inside the connecting seat. This causes the limiting block to descend and quickly clamp and fix the pipe to be bent. Furthermore, with the cooperation of the annular support frame, it effectively ensures that the pipe will not shift position during the bending mechanism's processing, thus avoiding the situation where the pipe moves during the bending process and interferes with the bending effect. Moreover, the setting of the T-shaped slide bar makes it easy for the operator to move the fixed bracket along the top of the worktable, thereby enabling the pipe bending machine to bend pipes of more sizes.

[0016] 2. This utility model, through the positioning groove and positioning post, makes it easy for workers to initially position and install the bending die at the bottom of the mounting plate. Then, through the cooperation of the locking mechanism, the bending die is quickly and elastically locked, thus providing convenience for workers to disassemble, install, replace, and maintain the bending mechanism.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 and Figure 3 As shown, a pipe bending machine for processing automotive parts includes a worktable 1 and a support bracket 4. An adjustment mechanism 2 is movably mounted on the inner surface of the worktable 1, and a support mechanism 3 is rotatably connected to the side of the adjustment mechanism 2. The support mechanism 3 includes a connecting mechanism 31, a connecting shaft 32, a connecting roller 33, and an annular support frame 34. The connecting mechanism 31 is fitted onto the outer surface of the adjustment mechanism 2, and the connecting shaft 32 is rotatably connected to the side of the connecting mechanism 31. The connecting roller 33 is fixedly mounted on the end of the connecting shaft 32, and the end of the connecting shaft 32 is fixedly connected to the end of the connecting roller 33. The other end of the connecting shaft 32 is rotatably connected to the side of the connecting mechanism 31. The connecting roller 33 forms a rotating structure with the connecting mechanism 31 through the connecting shaft 32. The connecting roller 33 and the connecting mechanism 31 ensure that the annular support frame 34 does not interfere with the bending process of the bending mechanism 7 when it is bearing and limiting the pipe fitting. At the same time, the annular support frame 34 is fixedly connected to the outer surface of the connecting roller 33. The top of the worktable 1 is slidably connected to the limiting component 8. The limiting component 8 includes a fixed bracket 81, a T-shaped slide bar 82, a threaded adjusting rod 83, a connecting seat 84, a limiting block 85, and a limiting guide rod 86. The T-shaped slide bar 82 is symmetrically fixedly installed at the bottom of the fixed bracket 81, and the threaded adjusting rod 83 is threadedly connected to the inside of the fixed bracket 81. The end of the threaded adjusting rod 83 is rotatably connected to the connecting seat 84. The bottom of the connecting seat 84 is fixedly installed with the limiting block 85, and the top of the limiting block 85 is symmetrically fixedly installed with the limiting guide rod 86.

[0023] like Figure 1 and Figure 2As shown, the support bracket 4 is fixedly installed on the top of the workbench 1, and a stamping cylinder 5 is installed on the top of the support bracket 4. A connecting assembly 6 is fixedly connected to the extension end of the stamping cylinder 5, and a bending mechanism 7 is movably installed at the bottom of the connecting assembly 6. The bending mechanism 7 includes a bending die 71, a limiting groove 72, and a positioning post 73. Limiting grooves 72 are symmetrically opened on both sides of the bending die 71. The internal dimensions of the limiting grooves 72 perfectly match the external dimensions of the arc-shaped locking block 644, and the arc-shaped locking block 644 forms a locking structure with the bending die 71 through the limiting grooves 72. The arc-shaped locking block 644 and the bending die 71, configured as a locking structure, allow the arc-shaped locking block 644 to be easily inserted into the bending die 71 to complete the locking operation. A positioning post 73 is symmetrically fixedly installed on the top of the bending die 71, and the positioning post 73 forms a locking structure with the mounting plate 61 through the positioning groove 62. This locking structure of the positioning post 73 and the mounting plate 61 facilitates the initial positioning and installation of the bending mechanism 7 onto the bottom of the mounting plate 61 by the operator. The connecting assembly 6 includes the mounting plate 61, the positioning groove 62, the connecting bracket 63, and the locking mechanism 6. 4. The bottom of the mounting plate 61 is symmetrically provided with positioning grooves 62, and a connecting bracket 63 is fixedly installed on the bottom of the mounting plate 61. Locking mechanisms 64 are symmetrically installed on both sides of the connecting bracket 63. The locking mechanism 64 includes a locking rod 641, a connecting plate 642, a pull ring 643, an arc-shaped locking block 644, and a locking spring 645. The end of the locking rod 641 is fixedly connected to the connecting plate 642, the end of the locking spring 645 is fixedly connected to the end of the connecting plate 642, and the other end of the locking spring 645 is fixedly connected to the outer surface of the connecting bracket 63. Furthermore, the connecting plate 642 forms an elastic structure with the connecting bracket 63 via the locking spring 645. With the connecting plate 642 and the connecting bracket 63 configured as elastic structures, when the operator releases the pull ring 643, the connecting plate 642 can use the rebound force to drive the locking rod 641 along with the arc-shaped locking block 644 into the interior of the bending mechanism 7 to complete the locking work. The other end of the connecting plate 642 is fixedly installed with the pull ring 643, and the other end of the locking rod 641 is fixedly installed with the arc-shaped locking block 644. At the same time, the end of the connecting plate 642 is fixedly connected with the locking spring 645.

[0024] In summary, this pipe bending machine for processing automotive parts is first based on... Figures 1 to 3As shown in the diagram, the operator grasps the bending die 71 and moves it towards the inner surface of the connecting bracket 63. At this time, due to the arc-shaped locking block 644 and the elastic force of the locking spring 645, the locking rod 641 drives the arc-shaped locking block 644 to move along the side of the bending die 71. When the bending die 71 is fully installed into the inner surface of the connecting bracket 63, the positioning pin 73 automatically inserts into the positioning groove 62 to complete the initial positioning installation. Simultaneously, the connecting plate 642, through the elastic force of the locking spring 645, drives the end of the locking rod 641 and the arc-shaped locking block 644 to insert into the limiting groove 72 to complete the locking operation. Then, the operator opens the adjustment mechanism 2 through the controller to adjust the load... The position of mechanism 3 is adjusted. After the position of bearing mechanism 3 is adjusted, the pipe to be bent is placed on the top of the annular bearing frame 34. Then, the position of fixed bracket 81 is quickly adjusted by sliding T-shaped slide bar 82. When fixed bracket 81 moves directly above the annular bearing frame 34, the threaded adjustment rod 83 is rotated. At this time, the guide sliding of limit guide rod 86 causes connecting seat 84 to drive limit block 85 to descend and clamp and limit the pipe. Then, the controller opens the stamping cylinder 5 on the top of bearing bracket 4, causing stamping cylinder 5 to drive connecting component 6 to move downward, thereby causing connecting component 6 to drive bending mechanism 7 to automatically bend the pipe below.
