Description

Technical Field

[0001] The invention relates to the technical field of steel bar processing, in particular to a processing device for steel bars in prefabricated concrete components. Background Art

[0002] Precast concrete components are components used in the fields of construction, transportation, water conservancy, etc. Compared with cast-in-place concrete, for construction workers, the relatively stable working environment in the factory has a higher safety factor than complex construction site operations. The quality and process of building components can be better controlled through mechanized production. The standardization of precast component sizes and characteristics can significantly speed up the installation speed and construction project progress. Compared with traditional on-site mold making, the molds in the factory can be reused and the overall cost is lower. Mechanized production requires less labor. As labor costs continue to rise, the cost advantage of precast components produced on a large scale will become more and more obvious.

[0003] In precast concrete components, we usually need to put in steel bars for processing, and the steel bars in precast concrete components generally need to be bent. During the bending process of steel bars for precast concrete parts, most steel bar bending devices can only process one by one, and cannot effectively control the bending length and bending angle. Moreover, the bending radius of the steel bars bent by the steel bar bending device is fixed and cannot be applied to a variety of sizes. The steel bar bending consumes a lot of time and is inefficient. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a processing device for steel bars in precast concrete components to solve the technical problems in the prior art that the steel bar bending device cannot be applied to processing with various bending radius requirements and the steel bar bending efficiency is low.

A plurality of steel bar placement grooves extending in the left-right direction are arranged at intervals in the front-to-back direction on the guide plate. The first fixing assembly and the second fixing assembly are used to fix the steel bars.

A limiting rod 32 extending in the front-rear direction is arranged on one of the unit blocks, and a bending channel for the steel bar to pass through is formed between the limiting rod 32 and the bending groove 27. It should be noted that the mechanical chuck 29 and the driving mechanism in the mechanical chuck 29 are prior art, and their specific structures and working principles are not described in detail here.

[0045] like Figure 1 and Figure 2 As shown, in the present embodiment, the radial position of the limit rod 32 along the driving shaft 23 is adjustable.
