Description

Square tube roll bending forming equipment

Technical Field

The invention relates to auxiliary equipment, in particular to square tube roll bending forming equipment.

Background

The galvanized square pipe is a hollow square section steel pipe with square section shape and size, which is made by using hot-rolled or cold-rolled galvanized strip steel as a blank, performing cold bending processing and forming, and then performing high-frequency welding, and is mainly used for curtain walls, buildings, machinery manufacturing and the like.

The square tube needs to be subjected to cold bending processing during manufacturing, namely, the square tube is subjected to plastic deformation at a temperature lower than the recrystallization temperature, so that the hardness and strength of the square tube can be better improved, the square tube is usually subjected to roll bending by directly using a tool, however, in the general roll bending method, if a cylinder capable of rotating is not adopted, the square tube is directly subjected to roll bending, so that the bending position is possibly creased, and subsequent processing is not facilitated.

Therefore, a square tube roll bending forming device which can enable the bending part of the square tube to be smooth and smooth so as to facilitate the subsequent processing of the square tube needs to be developed.

Disclosure of Invention

(1) Technical problem to be solved

The invention aims to overcome the defect that the bending part of a square pipe can generate creases when the square pipe is directly rolled in the prior art, and the technical problem to be solved by the invention is to provide the square pipe roll bending forming equipment which can enable the bending part of the square pipe to be smoother and smoother so as to facilitate the subsequent processing of the square pipe.

(2) Technical scheme

In order to solve the technical problem, the invention provides a square tube roll bending forming device, which comprises: the base is in a cuboid shape; the fixed clamping block is fixedly connected to the upper middle part of the base; the bearing blocks are symmetrically arranged on the base; the rotating shafts are all rotatably arranged in the bearing seats; the first rotating discs are arranged on the upper part of the rotating shaft; the first hexagonal screws are all arranged at the top end of the rotating shaft; the handles are arranged on the upper part of the rotating shaft and are positioned below the first rotating disc; the roll bending cylinders are rotatably arranged at the tops of the handles; the second hexagonal screws are all arranged at the top end of the roller bending cylinder; and the second rotating disc is arranged at the lower part of the roller bending cylinder and is in fit contact with the first rotating disc.

Preferably, also include: the gear, the gear all sets up the pivot bottom, this gear all is located in the base, intermeshing between the gear.

Preferably, the base is hollow on the inside.

Preferably, the distance between the rotating shaft and the roll bending cylinder is 20 mm.

Preferably, the height of the apparatus is 20 cm.

(3) Advantageous effects

1. The invention achieves the effect that the bending part of the square pipe can be smoother and smoother so as to facilitate the subsequent processing of the square pipe;

2. because this equipment adopts cylindric roller bending cylinder and the pivot that can rotate, carries out the roller bending to square pipe through roller bending cylinder and pivot, just can make the department of bending of square pipe more smooth rounding off.

Drawings

Fig. 1 is a schematic perspective view of the present invention.

Fig. 2 is a schematic top view of the present invention.

Fig. 3 is a partial perspective view of the present invention.

The labels in the figures are: the gear comprises a base 1, a fixed clamping block 2, a bearing seat 3, a first rotating disc 4, a rotating shaft 5, a first hexagonal screw 6, a handle 7, a roller-bent cylinder 8, a second hexagonal screw 9, a second rotating disc 10 and a gear 11.

Detailed Description

The invention is further described below with reference to the figures and examples.

Example 1

The utility model provides a square pipe roll bending former, as shown in fig. 1-3, including base 1, fixed clamp splice 2, bearing frame 3, first carousel 4, pivot 5, first hexagon screw 6, handle 7, roll bending cylinder 8, second hexagon screw 9 and second carousel 10, middle part fixedly connected with fixed clamp splice 2 on the base 1, bearing frame 3 is installed to the symmetry around on the base 1, equal rotary type is equipped with pivot 5 in the bearing

frame

3, 5 upper portions of pivot all are equipped with first carousel 4, first hexagon screw 6 is all installed on 5 tops of pivot, 5 upper portions of pivot all are equipped with handle 7, handle 7 is located first carousel 4 below, the equal rotary type in handle 7 top is equipped with roll bending cylinder 8, roll bending cylinder 8 top all installs second hexagon screw 9, roll bending cylinder 8 lower part is equipped with second carousel 10, second carousel 10 and first carousel 4 cooperation contact.

When people need to roll the square pipe, can use this equipment, at first place square pipe in fixed clamp splice 2, place the position that square pipe needs to be crooked between pivot 5 and the roller bend cylinder 8 of front and back both sides, reuse hand is held handle 7 and is outwards rotated certain angle to drive pivot 5 and roller bend cylinder 8 and rotate, and under pivot 5 and roller bend cylinder 8 self pivoted auxiliary action, just can be with square pipe both sides to the left side bending, then upwards take out by crooked square pipe can.
