Description

A pipe bending device for circular arc pipe fittings

technical field

The utility model relates to the field of outdoor furniture production, in particular to a pipe bending device for circular arc pipe fittings.

Background technique

In order to ensure durability and corrosion resistance, the existing outdoor seats are usually made of cast aluminum, and the armrests or some decorative rods of outdoor furniture are realized by bending hollow aluminum rods by bending equipment.

Existing aluminum tubes usually use 3-4 bending wheels for combined bending, but this bending method is more troublesome to pass through the feeding and unloading steps, and the bending speed is slow. Therefore, there is currently a need for a A device for fast bending of arc pipe fittings.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a pipe bending device for circular arc pipe fittings.

In order to achieve the above purpose, the technical scheme adopted by the present invention is: a pipe bending device for circular arc pipe fittings, which comprises a frame, a first bending pipe assembly arranged on the frame, and a rotating device arranged on the frame. A second elbow assembly, a driving assembly that drives the second completely rotated relative to the first elbow assembly, the first elbow assembly includes a first baffle plate disposed on the frame and adjusts the first elbow assembly. A first adjusting assembly for the position of the baffle plate, the second elbow assembly includes a rotating shaft, a rotating block rotatably arranged with the rotating shaft, a guide block disposed on the rotating block, and a sliding block disposed on the rotating block. The second baffle plate and the first air cylinder that drives the second baffle plate, the first air cylinder pushes the second baffle plate to clamp the pipe between the guide block and the second baffle plate.

Preferably, the first adjusting assembly includes a sliding track and an adjusting block fixedly arranged on the frame, and an adjusting screw threadedly connected with the adjusting block.

Preferably, the guide block and the rotating block are detachably connected.

Preferably, the guide block has a circular arc groove.

Preferably, the sides of the first baffle and the second baffle are provided with grooves arranged along the length direction.

Preferably, it also includes a positioning assembly disposed on the frame, the positioning assembly including a sliding positioning block and a second air cylinder for driving the positioning block.

Due to the application of the above-mentioned technical solutions, the present invention has the following advantages compared with the prior art:

Because the utility model prevents the pipe fittings from being positioned between the first elbow assembly and the second elbow assembly, the positioning assembly is driven by the second cylinder, and the second elbow assembly can be driven by the driving assembly after being clamped by the first cylinder. Rotating to bend the pipe fittings, the workers only need to put and pick up the parts in the whole process, which is more efficient.

Description of drawings

FIG. 1 is a schematic structural diagram of an embodiment.

In the above drawings: 1, frame; 2, first baffle; 3, sliding track; 4, adjusting block; 5, adjusting screw; 6, rotating shaft; 7, rotating block; 8, guide block; 9, second baffle; 10, the first cylinder; 11, the positioning block; 12, the second cylinder; 13, the pipe fittings.

Detailed ways

The present utility model is further described below in conjunction with the embodiment shown in the accompanying drawings:

Embodiment 1: Referring to FIG. 1 , a pipe bending device for circular arc pipe fittings includes a frame 1 , a first elbow assembly arranged on the frame A pipe bend assembly, a second drive assembly (not shown in the figure) that drives the second pipe bend completely to rotate relative to the first pipe bend assembly, the first pipe bend assembly includes a first baffle plate 2 arranged on the frame 1 and an adjustable first baffle plate 2 The position of the first adjustment assembly, the second elbow assembly includes a rotating shaft 6, a rotating block 7 rotatably arranged with the rotating shaft 6, a guide block 8 disposed on the rotating block 7, and a second baffle plate 9 slidably disposed on the rotating block 7 And the first cylinder 10 that drives the second baffle 9 , the first cylinder 10 pushes the second baffle 9 to clamp the pipe 13 between the guide block 8 and the second baffle 9 .

The first adjustment assembly includes a sliding track 3 and an adjustment block 4 that are fixedly arranged on the frame 1 , and an adjustment screw 5 that is threadedly connected to the adjustment block 4 .

The guide block 8 is detachably connected to the rotating block 7 . The guide block 8 has a circular arc groove.

The sides of the first baffle 2 and the second baffle 9 are both provided with grooves arranged along the length direction.

It also includes a positioning assembly arranged on the frame 1 , and the positioning assembly includes a sliding positioning block 11 and a second air cylinder 12 for driving the positioning block.

Because the utility model prevents the pipe 13 from being positioned between the first elbow assembly and the second elbow assembly and then drives the positioning assembly by the second cylinder, after being clamped by the first cylinder 10, the second elbow can be driven by the drive assembly. The pipe assembly is rotated to bend the pipe fittings 13, and the worker only needs to perform the operations of placing and picking up the pieces in the whole process, and the efficiency is high.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present invention, and its purpose is to enable those who are familiar with the technology to understand the content of the present invention and implement accordingly, and cannot limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention shall be included within the protection scope of the present invention.
