Description

A kind of steel bar intelligent heading equipment

technical field

The invention relates to the technical field of steel bar pier heads, in particular to an intelligent steel bar upsetting device.

Background technique

Prefabricated components refer to various components manufactured by preforming methods. Pre-formed manufactured components are usually completed in a specialist factory and then transported to the field for use. Among the prefabricated components, the concept of concrete prefabricated components is the most widely used. In the construction field, prefabricated components are usually equivalent to reinforced concrete prefabricated components or precast concrete.

At present, the heading machines for prestressed steel bars are all heading equipment with complex structures and large shapes. Cage behind the head, especially after the pile is cut at the construction site, the section of the steel bar cannot be upset. Due to the brittle and hard properties of the prestressed steel bar, it is impossible to thread the prestressed steel bar, which makes the butt and anchoring of the prestressed steel bar very difficult. .

It should be noted that the above content belongs to the technical cognition category of the inventor, and does not necessarily constitute the prior art.

SUMMARY OF THE INVENTION

In order to solve the above problems, the purpose of the present invention is to provide a kind of intelligent steel upsetting equipment. Steel bar for pier head.

In order to achieve the above purpose, the present invention proposes a kind of intelligent upsetting equipment for steel bars, which includes a clamping assembly and a pier head assembly, the clamping assembly can be sleeved on the outer side of the steel bar and clamps the steel bar; the pier head assembly includes: A connecting sleeve, a clamping assembly and a pressing assembly, the connecting sleeve is fixed with the clamping assembly and extends in a direction away from the clamping assembly to form a pier cavity, the clamping assembly and the compression assembly The steel bars are sequentially arranged in the pier head cavity, and the steel bars can pass through the clamping components and extend their ends into the pier head cavity so that the clamping components can clamp the steel bars, and the pressurizing components can be directed toward the pier head cavity. Movement towards or away from the end of the rebar to compress the end of the rebar. The upsetting equipment clamps the outer side of the steel bar through the clamping assembly to ensure the stability of the steel bar during the pier head. Do the piercing. During the operation of the pier head, first pass the steel bar through the clamping assembly and make the end of the steel bar enter the pier head cavity, operate the clamping assembly to clamp the fixed steel bar, and then pass the clamping assembly in the pier head cavity. The reinforcing bars in the pier head cavity are further fixed and clamped, so that the ends of the reinforcing bars are located between the clamping component and the pressing component. When a pier head is required, the pressurizing component can be operated to move toward the end of the steel bar, so that the pressurizing component exerts a force on the reinforcing bar between the clamping component and the pressurizing component, so that the section of the reinforcing bar is pierced.
