The mount 1 includes: a first rod 11, a second rod 12, a third plate 13 and a fourth plate 14; the first rod 11 is composed of four vertical H-shaped steels. In order to ensure the stability of the holder 1. The four first rods 11 are divided into two groups, the tops of each group of two vertical first rods 11 are connected through second rods 12, the second rods 12 are H-shaped steel, the middle parts of the two second rods 12 are connected with third plates 13, and the third plates 13 are steel plates; 2 fourth plates 14 vertical to the third plates 13 are welded below the middle parts of the third plates 13; the fourth plate 14 is a steel plate, and the vertically arranged fourth plate 14 is connected with the top end of the hydraulic oil cylinder 2 (the pressing part is the hydraulic oil cylinder 2) through a pin shaft.
A limiting plate 3 is arranged in the middle of the fixing frame 1 (the limiting part is the limiting plate 3), a round hole is arranged in the middle of the limiting plate 3, and the hydraulic oil cylinder 2 penetrates through the round hole and is limited by the round hole; spacing portion sets up with the H shaped steel of four vertical settings is perpendicular, plays the effect that 2 horizontal directions of restriction hydraulic cylinder rocked. The telescopic end of the hydraulic oil cylinder 2 is arranged below the limit plate 3.
The lower part of the fixing frame 1 is provided with a supporting plate 4 (the supporting part is the supporting plate 4), and the supporting plate 4 and the limiting plate 3 are both rectangular. The support plate 4 is used to support the bending mould 5.
The telescopic end below the pressing device is movably connected with the tensioning part.
The hangers 8 of the tensioning portion are vertically arranged plates, through holes are formed in the upper portions of the plates, the telescopic ends of the tensioning portions are connected with the through holes through pins, the tensioning blocks 9 connected with the hangers 8 can rotate by a certain angle along the pins, and the tensioning blocks 9 are located on the same vertical plane with the telescopic ends of the pressing devices due to the gravity under the conventional condition. The advantage of the movable connection is that it is easy to disassemble. The tensioning block 9 is a wearing part and needs to be replaced after a period of time.
The bottom end surface of the tensioning block 9 is of an arc structure, and the radian of the arc is the same as that of the arc-shaped groove 6.
Specifically, the tensioning part comprises a hanging lug 8 and a tensioning block 9; the upper edge of the tensioning block 9 is fixedly connected with oppositely arranged hangers 8; one end of the hanging lug 8, which is far away from the tension block 9, is movably connected with the telescopic end of the pressing device.
In particular, the bending die 5 is fixed above the support.

Specifically, the clamping groove 7 is arranged on the end face above the bent grinding tool; the number of the clamping grooves 7 is two; and the groove walls on the two sides of the arc-shaped groove 6 are vertically connected with the clamping groove 7.
The bending die 5 is used as an important part for bending the steel bars, the clamping grooves 7 on the bending die 5 are wearing parts, and after the bending die is used for a period of time, due to the fact that a large number of steel bars are bent, the clamping grooves 7 need to bear the force for bending the steel bars every time. The damage of the card slot 7 needs to be at the damaged position by using an iron block for welding.
The technical problem can be solved by the following ways in the technology:
the clamping groove 7 and the bending die 5 are designed in a split mode, more than one hole is formed in the bending die 5 below the clamping groove 7, protrusions are arranged below the clamping groove 7, the number of the protrusions is the same as that of the holes, and the protrusions are inserted into the holes. The fixation of the card slot 7 is realized. When the clamping groove 7 is damaged, the clamping groove 7 can be directly taken down and replaced.

A bar bender, further comprising: an emergency braking system and a control system; the control system and the emergency braking system are connected with the pressing device.
The emergency braking system and the control system are not designed with software.
The emergency braking system is a braking system which judges whether emergency braking is needed or not according to the set moving speed. The emergency braking system is connected to a hydraulic ram 2. When the telescopic end of the hydraulic oil cylinder 2 moves to exceed the set speed, the emergency braking system stops the work of the hydraulic oil cylinder 2 and cuts off the power.
The control system is a controller for controlling the work of the hydraulic oil cylinder 2.
The operating priority of the emergency braking system is greater than the operating priority of the control system.
The emergency braking system is an existing system, belongs to the prior art, and avoids accidents caused by faults of the hydraulic oil cylinder 2.
The control system is a conventional hydraulic ram 2 control system and is of the prior art and is used here to facilitate understanding of hydraulic ram 2.
The working principle is as follows:
the steel bar to be processed is placed on the clamping groove 7, a worker holds one end of the steel bar by hand, the telescopic end of the hydraulic oil cylinder 2 is controlled to move downwards through the control system, the tensioning block 9 presses the steel bar downwards, the steel bar is deformed, and the steel bar is bent in a certain radian due to the fact that the contact surface of the tensioning block 9 and the steel bar is of an arc-shaped structure.
The clamping groove 7 can prevent the reinforcing steel bars from moving in the horizontal direction.
When the reinforcing bar is bent to the required radian, the controller controls the telescopic end to reset. When the hydraulic oil cylinder 2 breaks down, the emergency braking system performs emergency braking to avoid the telescopic end from continuously moving downwards.
The tensioning block 9 can be replaced by removing the connection between the hanging lug 8 and the telescopic end when the tensioning block 9 needs to be replaced. Is convenient and quick.
The clamping groove 7 can be detachably connected with the bending die 5, and the clamping groove 7 is used as a quick-wear part and is convenient to replace quickly. The connection between the clamping groove 7 and the bending die 5 can be realized in a plug-in manner and the like.
