Description

Technical Field

[0001] This utility model relates to the field of rebar bending machines, and in particular to the support structure on the bending head of a rebar bending machine. Background Technology

[0002] Existing rebar bending machines include a central shaft, a bending shaft, and a support structure. The support structure is relatively fixed, with the bending shaft and support structure located on the left and right sides of the central shaft, respectively. When a rebar is inserted between the central shaft and the bending shaft, the bending shaft rotates the rebar around the central shaft, causing the rebar to press tightly against the support structure and the central shaft, thus bending the rebar and performing operations such as hoop bending. The distance between the upper end of the support structure and the lower end of the central shaft needs to be adjusted according to the thickness of the rebar; the thicker the rebar, the greater the distance, and vice versa. This ensures the bending accuracy of the rebar. Previously, the height of the support structure was not adjustable, and the distance between them was adjusted by replacing the entire support structure, which was cumbersome and wasteful of resources. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a steel bar bending and hoop support structure that is easy to adjust in height.

[0004] This utility model achieves the above objectives as follows:

[0005] The steel bar bending support structure includes a fixed block located on the same side of the central axis and the bending axis, a movable block inserted into the fixed block, and several detachable gaskets installed between the movable block and the fixed block.

[0006] The gasket has several through holes, which correspond to the columns fixed on the fixed block or the movable block, and the gasket is fitted onto the columns.

[0007] The fixed block and the movable block each have two and three columns, respectively. The columns on the movable block are thicker and longer than those on the fixed block. The fixed block and the movable block each have a through hole for inserting the columns of the movable block and the fixed block.

[0008] The second through hole on the fixed block extends through the entire fixed block from top to bottom, while the second through hole on the movable block is a countersunk hole.

[0009] The free end of the column is hemispherical.

[0010] The movable block has a groove on its surface, and a support roller is installed in the groove. The support roller is higher than the surface of the movable block.

[0011] The support roller is constrained on the movable block by pressure plates at both ends of the movable block.

[0012] The fixed block is provided with a boss, and the outer side of the boss is flush with the outer side of the rotating block on which the central shaft and the bending shaft are installed.

[0013] The beneficial effects of this invention are as follows: Because the fixed block and the movable block are connected by an insertion joint, the movable block can be easily separated from or connected to the fixed block. When the steel bar to be bent is thin, and it is necessary to raise the height of the support structure and reduce the distance between the upper end of the support structure and the lower end of the central axis, simply remove the movable block from the fixed block, place a shim on the fixed block, and then insert the movable block back in; otherwise, the process is reversed. The operation is simple and convenient, eliminating the need to replace the entire support structure and reducing user costs. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0015] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0016] Figure 2 This is a schematic diagram of the structure of the movable block of this utility model;

[0017] Figure 3 This is a schematic diagram of the structure of the present invention after the movable block is removed. Detailed Implementation

[0018] Reference Figures 1 to 3 The rebar bending support structure includes a fixed block 3 located on the same side of the central axis 1 and the bending axis 2. A movable block 4 is inserted into the fixed block 3, and several detachable shims 5 are installed between the movable block 4 and the fixed block 3. Since the fixed block 3 and the movable block 4 are connected by an insertion joint, the movable block 4 can be easily separated from or connected to the fixed block 3. When the rebar to be bent is thin, and it is necessary to raise the height of the support structure and reduce the distance between the upper end of the support structure and the lower end of the central axis, simply remove the movable block 4 from the fixed block 3, place the shims 5 on the fixed block 3, and then insert the movable block 4 back in; otherwise, the process is reversed. The operation is simple and convenient, requiring no replacement of the entire support structure, thus reducing user costs.

[0019] The gasket 5 has several through holes 6, which correspond to the columns 7 fixed on the fixed block 3 or the movable block 4. The gasket 5 is fitted onto the columns 7. This allows for easy adjustment of the height of the entire support structure by adding or removing gaskets 5, and adjustment of the distance between the upper end of the support structure and the lower end of the central shaft.

[0020] In addition, the fixed block 3 and the movable block 4 have two and three columns 7 respectively. The columns 7 on the movable block 4 are thicker and longer than those on the fixed block 3. Both the fixed block 3 and the movable block 4 have through holes 8 for inserting the columns 7. When the steel bar to be bent is thicker, the number of shims 5 needs to be reduced. In this case, the columns 7 on the fixed block 3 will extend into the through holes 8 on the movable block 4, and vice versa. This helps to withstand the greater stress generated between the movable block 4 and the fixed block 3 when bending thicker steel bars, preventing damage to the support structure. The through holes 8 on the fixed block 3 extend through the entire fixed block vertically, while the through holes 8 on the movable block 4 are countersunk holes, accommodating the thicker and longer columns 7 on the movable block 4, and meeting the requirements for bending steel bars of different specifications.

[0021] To facilitate the insertion of the column 7 into the through hole 8, the free end of the column 7 is hemispherical.

[0022] To reduce the frictional force of the reinforcing bars moving on the supporting structure, a groove 9 is provided on the surface of the movable block 4, and a support roller 10 is installed in the groove 9, with the support roller 10 protruding above the surface of the movable block 4. The support roller 10 is in direct contact with the reinforcing bars. When the reinforcing bars move, the support roller 10 rotates, changing sliding friction to rolling friction, reducing frictional force, and facilitating the movement or bending of the reinforcing bars. The support roller 10 is constrained on the movable block by pressure plates 11 at both ends of the movable block 4, thereby preventing the support roller 10 from axially disengaging.

[0023] Furthermore, the fixing block 4 is provided with a boss 12, the outer side 13 of which is flush with the outer side 15 of the rotating block 14 on which the central shaft 1 and the bending shaft 2 are installed. By aligning one end of the support structure with the outer side 13 of the boss 12, it can be conveniently and accurately installed onto the fixing block 4, while ensuring that the support structure properly supports the steel bar to be bent.
