Abstract

The invention discloses a helical straightening mechanism for a steel pipe straightening machine, relates to the field of construction machinery, and mainly includes a hyperbolic straightening roller, a mounting plate, an end plate, a transmission wheel, and a shaft end. The hyperbolic straightening roller is installed on the mounting plate, and the fitting degree between the hyperbolic straightening roller and the steel pipe is adjusted and fastened by bolts. The mounting plate is connected with the end plate, and the transmission wheel and the shaft end are connected with the end plate. The boards are socketed together. The hyperbolic straightening rollers surround the steel pipe (the workpiece to be repaired) and are evenly distributed in three equal parts in the circumferential direction, and form a triangular fulcrum between any three hyperbolic straightening rollers. The invention has the beneficial effects of good straightening effect of the steel pipe, compact structure, high working efficiency and long service life, and because the whole mechanism forms a cage structure, the rigidity of the whole mechanism is improved, and the cost input is small.

Description

Spiral straightening mechanism

technical field

The invention relates to the field of construction machinery, in particular to a helical straightening rotary box mechanism for a steel pipe straightening machine of the construction machinery.

Background technique

At present, in the field of steel pipe straightening machines, the most common straightening turret mechanism uses a square turret, and the arrangement of the hyperbolic straightening rollers in it is generally only double rows, which cannot make the steel pipe in the straightening process Uniform straightening points are formed in the circumferential direction, and the straightening effect is poor. Due to the large volume of the entire steering, it is impossible to add multiple straightening points in a limited space, resulting in very low production efficiency.

Contents of the invention

The object of the present invention is to overcome the deficiencies in the above-mentioned background technology, and provide a combined traveling clamp for a steel pipe straightening machine.

The technical scheme adopted for realizing the above purpose is:

The spiral straightening mechanism includes a mounting plate, an end plate, a hyperbolic straightening roller, a mounting plate, a connecting frame, a wire brush, a transmission wheel and a shaft end, and the hyperbolic straightening roller is installed on the mounting plate, and The fit between it and the workpiece can be adjusted and fastened by bolts, the mounting plate and the end plate are connected together, and the transmission wheel and the shaft end are sleeved on the outside of the end plate. The hyperbolic straightening rollers are evenly distributed in three equal parts around the workpiece (repaired steel pipe) in the circumferential direction, and form a triangular fulcrum between any three hyperbolic straightening rollers.

Preferably, the mounting plate is mounted on a hexagonal end plate, and is evenly arranged in three equal parts around the steel pipe in the circumferential direction.

The beneficial effects of the present invention are: good straightening effect of the steel pipe, compact overall structure, high working efficiency, less loss of components, and because the entire mechanism forms a cage structure, the rigidity of the entire mechanism is also improved, thereby prolonging the service life and reducing the cost. Less investment.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

Embodiment 1: as shown in Fig. 1 and Fig. 2, the present invention is a spiral type straightening mechanism, comprises mounting plate 1, end plate 2, hyperbolic straightening roller 3, mounting plate connecting frame 4, steel wire brush 5, Transmission wheel 6 and shaft end 7. The hyperbolic straightening roller 3 is installed on the mounting plate 1, and the fitting degree between the fastening hyperbolic straightening roller 3 and the steel pipe 8 is adjusted and fastened by bolts, the mounting plate 1 and the end plate 2 are connected together, and the transmission wheel 6 and the shaft end 7 are both sleeved on the outside of the end plate 2. The hyperbolic straightening rollers 3 are evenly distributed in three equal parts around the steel pipe 8 in the circumferential direction, and form a triangular fulcrum between any three hyperbolic straightening rollers 3 .

When working, as shown in Figure 3, the helical straightening mechanism 10 is installed between two bearing housings 11 and connected to the rotary box motor 15 through a chain, and the front end linear transmission mechanism 13 and the tail end linear transmission mechanism 14 pass through the chain. Connected, and connected with the motor 16 for linear transmission. When the two motors are running, the front linear transmission mechanism 13 will push the steel pipe 8 into the transfer box mechanism 10, the transfer box mechanism 10 will rotate, and the steel pipe 8 and the hyperbolic straightening roller 3 will produce a spiral motion, so that the uneven steel pipe 8 Realize straightening lines.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone familiar with the technical field within the technical scope disclosed in the present invention, according to the technical solution of the present invention Equivalent replacements or changes to the inventive concepts thereof shall fall within the protection scope of the present invention, and the protection scope of the present invention shall be determined by the claims and their equivalents.
