Steel-bar automatic hoop bender with synchronous belt drive mechanism

Abstract

The invention discloses a reinforcing steel bar automatic hoop bending machine which is provided with a synchronous belt drive mechanism; the reinforcing steel bar automatic hoop bending machine comprises a traction mechanism, an aligning mechanism, a bending mechanism and a cutting mechanism; the invention also comprises a synchronous belt drive mechanism; the synchronous belt drive mechanism is arranged on the input end of the traction input shaft of the traction mechanism and the input end of the input shaft of the bending mechanism; the synchronous belt drive mechanism comprises a servo motor, driving pulleys, driven pulleys and a synchronous belt; the driving pulleys are arranged on the servo motor output shaft and the driven pulleys are separately arranged on the input end of the traction input shaft and the input end of the input shaft of the bending mechanism; the synchronous belt connects the driving pulleys and the driven pulleys. The invention has the beneficial effects that the precise transmission speed and position can be realized and the weight is light; the moment of inertia is small and the cost and noise are greatly reduced; moreover, the maintenance is convenient. The center-to-center distance between the driving pulleys and driven pulleys can be adjusted and the internal collocation is rational; therefore, the overall dimension of the reinforcing steel bar automatic hoop bending machine can be reduced.

Description

technical field [0001] The invention relates to an automatic hoop bending machine for steel bars, in particular to an automatic hoop bending machine for steel bars with a synchronous belt transmission mechanism. Background technique [0002] With the rapid development of economic construction, the automatic processing equipment for stirrups - the automatic bending machine for steel bars has been widely used. The prior art steel bar automatic hoop bending machine comprises: a traction mechanism, a straightening mechanism, a bending mechanism and a shearing mechanism. figure 1 It is the front view of the traction mechanism and the bending mechanism of the automatic hoop bending machine for steel bars in the prior art: figure 2 yes figure 1 top view. [0003] Such as figure 1 , figure 2 As shown, the traction mechanism of the prior art steel bar automatic hoop bending machine includes: the servo motor 2a is connected to the reducer 8a, and the output shaft of the reducer...

AI Technical Summary

Problems solved by technology

[0008] 1. The moment of inertia of the reducer is relatively large, the response speed is slow when starting and stopping at high speed and forward and reverse, and the power loss is large

[0009] 2. During the working process, due to the relatively large power of the servo motor, frequent acceleration and deceleration and positive and negative rotations lead to poor working conditions of the reducer, resulting in low life of the reducer, frequent damage to the reducer, and inconvenient maintenance and replacement

[0010] 3. There is a gap between the internal gears of the reducer, which makes the product precision low and causes the zero drift of the system to be unstable during closed-loop control

[0011] 4. The cost of the reducer is high, the weight is large, and the volume is large, resulting in a large size of the steel bar automatic hoop bending machine, and it is difficult to achieve a compact arrangement between the components, which leads to an increase in the weight and cost of the whole machine; the maintenance cost is large, and human and material resources are required.
