Abstract

The utility model discloses a device for eliminating steel-pipe bend on cold-drawing bench, which is characterized in that the right lateral surface of a die plate (1) is provided with a tick shape circular cylinder adjustable die sleeve (2); the middle part in the vertical direction of the tick shape circular cylinder adjustable die sleeve (2) is provided with a screw rod (4), and both ends of the screw rod (4) is provided with a screw nut (3); the die plate (1) and the tick shape circular cylinder adjustable die sleeve (2) are connected into integration; the middle part in the horizontal direction of the tick shape circular cylinder adjustable die sleeve (2) is provided with an adjustable point (5), and the inner part of the tick shape circular cylinder adjustable die sleeve (2) is provided with a circular cylinder sizing mold (7). The main application of the utility model is to prevent bending phenomena during the pipe drawing process, reduce straightening procedures, improve the material producing rate, and reduce the cost.

Description

Device for eliminating steel-pipe bend on cold-drawing bench

The utility model relates to a kind of pipe drawing device, especially a kind of device of eliminating tube bending on drawbench.

Past steel pipe in Cold Drawing Process bends easily, must align with straightener, relate to shape tube, mostly adopt the three point force machine to align, but use the three point force machine except rectify straight, load mould also appears easily, on the surface of steel pipe depression points appears just, not only influence product quality, and influence lumber recovery; Pipe mostly adopts straightener such as seven rollers to align, and this straightener makes defectives such as steel pipe abrades easily, spiral, reduces the steel pipe lumber recovery.

The purpose of this utility model provides a kind of device of eliminating tube bending on drawbench.

The utility model is achieved like this: have on the right flank of template be " √ " type shape drum type brake adjustability die sleeve, the middle part has a screw rod on " √ " shape drum type brake adjustability die sleeve vertical direction, on the two ends of screw rod, has nut, template and die sleeve are connected as a single entity, the middle part has the adjustment point on the horizontal direction of " √ " shape drum type brake adjustability die sleeve, has the drum type brake plug die in " √ " shape drum type brake adjustability die sleeve.

" √ " shape drum type brake adjustability die sleeve vertical direction and template also can adopt whole or integrally welded.

During use, the point of adjustment at any time remains on the same horizontal center line steel pipe, prevents bending.

The utility model compared with prior art has following advantage:

1, adopt after this device, the flexibility of steel pipe will reduce greatly in the Cold Drawing Process, need not align basically;

2, solved the defective that causes to steel pipe because of in the aligning process, as load mould, scratch etc.;

3, reduced production cost, improved lumber recovery, reduced basically and align operation together, economic effect obviously improves.

Concrete structure of the present utility model and embodiment are provided by the following drawings.

Fig. 1 is that general structure of the present utility model is cutd open and shown schematic diagram.

To be described in further detail concrete structure of the present utility model and embodiment below in conjunction with accompanying drawing.

Shown in accompanying drawing 1, middle part in template 1 has through hole, in the hole, has finishing die 6, finishing die 6 is tapered, interior diameter is left small and right large, on the right flank of template 1, have and be " √ " shape drum type brake adjustability die sleeve 2, the middle part has screw rod 4 on " √ " shape drum type brake adjustability die sleeve 2 vertical direction, run through template 1, have nut 3 at the two ends of screw rod 4, play the role of fastening, " √ " shape drum type brake adjustability die sleeve 2 vertical direction and template 1 also can adopt whole or integrally welded, the middle part has the point of adjustment 5 on the horizontal direction of " √ " shape drum type brake adjustability die sleeve 2, have plug die 7 and contact with adjusting point 5 in " √ " drum type brake adjustability die sleeve 2, the planform of plug die is identical with finishing die, when steel pipe 8 passes through from right to left, steel pipe 8 can be remained on the same horizontal line, make steel pipe 8 be difficult for flexural deformation.

Claims

1, a kind of device of on drawbench, eliminating tube bending, it comprises template (1), finished product template (6), it is characterized in that: on the right flank of template (1), have and be " √ " shape drum type brake adjustability die sleeve (2), the middle part has screw rod (4) on " √ " shape drum type brake adjustability die sleeve (2) vertical direction, on the two ends of screw rod (4), has nut (3), template (1) and " √ " shape drum type brake adjustability die sleeve (2) are connected as a single entity, the middle part has adjustment point (5) on the horizontal direction of " √ " shape drum type brake adjustability die sleeve (2), has drum type brake plug die (7) in " √ " shape drum type brake adjustability die sleeve (2).

2, according to right 1 described a kind of device of eliminating tube bending on drawbench, it is characterized in that: " √ " shape drum type brake adjustability die sleeve (2) vertical direction and template (1) also can adopt whole or integrally welded.
