Description

Technical Field

[0001] The utility model relates to the technical field of bending devices, and specifically relates to a steel bar bending device convenient for positioning. Background Technique

[0002] A steel bar bending device is a mechanical device used to bend steel bars into specific shapes. It can bend steel bars into various angles and shapes, such as right angles, acute angles, obtuse angles, etc. The steel bar bending device is widely used in the field of construction engineering and is one of the important devices for steel bar processing.

[0003] When the existing steel bar bending device is used, it is necessary to fix the steel bar. However, most of the fixing methods only fix one part of the steel bar and cannot ensure that the axis of the steel bar remains horizontal, which may cause the steel bar to shift during bending, resulting in a deviation in the bending angle. Content of the Utility Model

[0004] The purpose of the utility model is to provide a steel bar bending device convenient for positioning to solve the problems raised in the above background technique.

The positioning part includes:

[0006] A positioning column, the side surface of the positioning column is fixedly connected with the inside of the bracket, the top surface of the positioning column is fixedly connected with a limiting block, a moving bar penetrates through the inside of the limiting block, the bottom surface of the moving bar is fixedly connected with a connecting rod I, and one end of the connecting rod I away from the moving bar is fixedly connected with a push plate;

Pull up the reset block so that the reset block drives the insertion rod not to insert into the clamping hole on the surface of the moving bar.

[0008] Preferably, the positioning column is penetrated by an arc-shaped slider. After the steel bar is pushed a certain distance, it will push the push plate, and the push plate will drive the moving bar to slide along the limiting block through the connecting rod I. At the same time, when the moving bar moves, it will drive the contact ring II to gradually contact the inclined surface of the inclined surface block through the connecting rod II, thereby forcing the inclined surface block to drive the arc-shaped slider to contract towards the center of the positioning column, and the arc-shaped slider is slidably connected with the positioning column.

[0009] Preferably, one side surface of the arc-shaped slider close to the contact ring is fixedly connected with an inclined surface block, and the inclined surface block penetrates through the positioning column and is slidably connected.

[0010] Preferably, a support rod penetrates and is slidably connected to the bottom end of the arc-shaped slider. The inclined plane block drives the arc-shaped slider to contract towards the center of the positioning column. At the same time, when the arc-shaped slider contracts, the arc-shaped spring is compressed. And the arc-shaped slider drives the positioning block to clamp the steel bar through the support rod. And through the two groups of positioning columns, the axis of the steel bar can be kept parallel to the horizontal line. One end of the support rod away from the arc-shaped slider is fixedly connected with a positioning block.

The top end of the plug rod is fixedly connected with a reset block. A second spring is fixedly connected between the reset block and the limiting block. After starting the bending cylinder to lift the bending block to bend the positioned steel bar, pull up the reset block to make the reset block drive the plug rod to no longer insert into the moving bar, then the arc-shaped moving bar can be pulled out. And the compressed arc-shaped spring will push the arc-shaped slider to reset.

[0012] Preferably, the number of the arc-shaped sliders is three groups, and an arc-shaped rod penetrates between every two groups of the arc-shaped sliders. At the same time, an arc-shaped spring is fixedly connected between every two groups of the arc-shaped sliders.

[0013] Compared with the prior art, the utility model provides a steel bar bending device convenient for positioning, and has the following beneficial effects:

[0014] For this steel bar bending device convenient for positioning, the push plate drives the moving bar to slide along the limiting block through the first connecting rod.

At the same time, when the arc-shaped slider contracts, the arc-shaped spring is compressed. And the arc-shaped slider drives the positioning block to clamp the steel bar through the support rod. And through the two groups of positioning columns, the axis of the steel bar can be kept parallel to the horizontal line, avoiding the steel bar from shifting due to excessive force of the bending cylinder during bending.

One end of the second connecting rod 210 away from the moving bar 23 is fixedly connected with a resisting ring 29. A clamping hole 211 is formed on the surface of the moving bar 23. During use, place the steel bar to be bent on the bracket 3 and push it, so that the steel bar passes through the positioning post 21, and continuously push the steel bar, pull up the reset block 220, so that the reset block 220 drives the insertion rod 219 not to insert into the clamping hole 211 on the surface of the moving bar 23. The arc-shaped slider 212 penetrates through the positioning post 21. After the steel bar is pushed a certain distance, it will push the push plate 28, and the push plate 28 will drive the moving bar 23 to slide along the limiting block 22 through the first connecting rod 24. At the same time, when the moving bar 23 moves, it will drive the resisting ring 29 to gradually resist the inclined surface of the inclined surface block 213 through the second connecting rod 210, thereby forcing the inclined surface block 213 to drive the arc-shaped slider 212 to contract towards the center of the positioning post 21, and the arc-shaped slider 212 is slidably connected to the positioning post 21. One side surface of the arc-shaped slider 212 close to the resisting ring 29 is fixedly connected with an inclined surface block 213, and the inclined surface block 213 penetrates through the positioning post 21 and is slidably connected. The bottom end of the arc-shaped slider 212 penetrates through and is slidably connected with a support rod 214.

At the same time, when the arc-shaped slider 212 contracts, the arc-shaped spring 218 will be compressed, and the arc-shaped slider 212 will drive the positioning block 215 to clamp the steel bar through the support rod 214. Through two groups of positioning posts 21, the axis of the steel bar can be kept parallel to the horizontal line. One end of the support rod 214 away from the arc-shaped slider 212 is fixedly connected with a positioning block 215.

After the steel bar is pushed a certain distance, it will push the push plate 28, and the push plate 28 will drive the moving strip 23 to slide along the limit block 22 through the first connecting rod 24. At the same time, when the moving strip 23 moves, it will drive the second abutting ring 29 to gradually abut against the inclined surface of the inclined block 213 through the second connecting rod 210, thereby forcing the inclined block 213 to drive the arc-shaped slider 212 to contract towards the center of the positioning column 21. At the same time, when the arc-shaped slider 212 contracts, the arc-shaped spring 218 will be compressed, and the arc-shaped slider 212 will drive the positioning block 215 to clamp the steel bar through the support rod 214. And through the two groups of positioning columns 21, the axis of the steel bar can be kept parallel to the horizontal line, avoiding the steel bar from shifting due to excessive force of the bending cylinder 4 during bending. After starting the bending cylinder 4 to lift the bending block 5 to bend the positioned steel bar, pull up the reset block 220, so that the reset block 220 drives the insertion rod 219 not to insert into the moving strip 23 anymore, then the arc-shaped moving strip 23 can be pulled out, and the compressed arc-shaped spring 218 will push the arc-shaped slider 212 to reset.
