Description

A kind of portable small diameter tube single pole swan neck system

Technical field

The utility model relates to building field, in particular to swan neck system field, specifically a kind of portable small diameter tube list Bar swan neck system.

Background technique

Building engineering field often relates to a large amount of building installation engineerings, needs pre-buried electric conduit more in main structure top plate For 20-50mm small diameter tube iron pipe, construction need to be according to design drawing brake forming, this is just needed using angle pipe equipment or machine to pipe Road carries out bending for different angle.Automatic bend pipe equipment is often used in construction site, has the characteristics that high-efficient, but equipment is heavy, adds Work need to be completed in production room, and procuring equipment higher cost；Currently on the market single-handle type, two handles Manual pipe bender type also compared with It is more, fixture, bracket need to be cooperated to bend iron pipe, it is cumbersome although can be saved many times for operator, no It directly can directly bend to steel tubing pipe tool, and Manual pipe bender higher cost currently on the market.

Utility model content

The utility model aims to solve the problem that more, the cumbersome and at high cost technical problem of existing manual swan neck system accessory. For this purpose, the utility model proposes a kind of portable small diameter tube single pole swan neck system, have that at low cost, speed is fast, production and uses Simplicity is flexible, can directly bend to steel class small diameter tube pipe tool, uses particularly suitable for construction site Pipe installing scene.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

Why a kind of portable small diameter tube single pole swan neck system, including pipe die (are referred to as pipe die, are because of work piece Forming shape determined by pipe die, inherently will act on it is similar with mold), the pipe die be semicircle bend pipe structure, it is so-called partly Circle bend pipe structure refers to that (bend pipe cuts off half, there are many kinds of cutting for structure that the cross section for forming bend pipe excision half is semicircle Except method, but eventually forming the cutting method that cross section is semicircle is to cut off along its axial face, only axial direction here Face is the vertical curved surface of arc), the front of the pipe die forms the accommodating card slot of work piece, the back side, and fixed there are two braced wings Plate is fixed with support shaft between two support wing plates, ratchet is fixed in the support shaft, is also hinged with hand in the support shaft Handle, is hinged with the pawl with ratchet cooperation on the handle, and the click cooperation is to realize handle to being processed (click is machinery field common structure to part bending direction one-directional rotation, to realize intermittent single direction rotation, here ingeniously It is wonderful to use click, it can smoothly be realized when handle is rotated to workpiece bending direction, but if reversed turn, then click Can be clamped, and ratchet is fixed, so it can be prevented reversely to turn, the meaning for preventing it reversely to turn here be it is laborsaving because this Sample can avoid repeating to do work, and reduce labour), also it is hinged with that (claw is adopted to the claw that is clamped work piece on the handle With conventional machinery mechanism all can, as long as can be realized the clamping of work piece).In use, by one end card of work piece It connects on the claw, and manually pawl is pulled and makes it away from ratchet, reversion handle to be stuck in claw to proper angle Work piece be partially disposed in the card slot of pipe die, at this point, operator's foot slams the pipe die and simultaneously puts pawl Under engage it with ratchet, start manually to pull handle, handle drives claw rotation, and claw drives work piece rotation, due to The limitation of pipe die, work piece can be bent along the card slot of pipe die, until shape needed for being formed.Here, it is preferred that being wanted for processing Seek angle work piece identical with the pipe die angle, but if required angle be greater than pipe die angle can also, only It is higher to operator's level requirement, operator only need it is curved to required angle stopping pull handle.

The beneficial effects of the utility model are: the utility model provides a kind of portable small diameter tube single pole swan neck system, if The structures such as pipe die, claw, ratchet mechanism are equipped with, work piece is stuck in pipe die, using pipe die as fulcrum, clawed end portions apply Power forms lever principle, the bending of product can be easily realized very much, and ingenious with ratchet mechanism, so that operation is more It is laborsaving reliable；In addition, entire product structure is simple, the structures such as additional fixture are not required to, equipment cost is lower.

Detailed description of the invention

Specific embodiment

Referring to figs. 1 to Fig. 2, a kind of portable small diameter tube single pole swan neck system of the utility model, including pipe die 1, it is described Pipe die 1 is semicircle bend pipe structure, and so-called semicircle bend pipe structure refers to that the cross section for forming bend pipe excision half is the knot of semicircle Structure, the front of the pipe die 1 forms the accommodating card slot of work piece 8, the back side, and fixed there are two support wing plate 2, two braced wings It is fixed with support shaft 3 between plate 2, ratchet 4 is fixed in the support shaft 3, handle 6 is also hinged in the support shaft 3, it is described The pawl 5 with the ratchet 4 cooperation is hinged on handle 6,4 pawl 5 of the ratchet cooperation is to realize handle 6 to work piece 8 bending directions one-directionally rotate, and the claw 7 to be clamped work piece 8 is also hinged on the handle 6.In use, will be processed One end of part 8 is connected on the claw 7, and is manually pulled pawl 5 and made it away from ratchet 4, reversion handle 6 to proper angle So that the work piece 8 being stuck in claw 7 is partially disposed in the card slot of pipe die 1, at this point, operator's foot slams the pipe Mould 1, which simultaneously simultaneously puts down pawl 5, engages it with ratchet 4, starts manually to pull handle 6, handle 6 drives the rotation of claw 7, claw 7 drive work piece 8 to rotate, and due to the limitation of pipe die 1, work piece 8 can be bent along the card slot of pipe die 1, until forming institute Need shape.Here, it is preferred that being used for processing request angle work piece 8 identical with 1 angle of pipe die, but if require angle Degree be greater than pipe die 1 angle can also, it is only higher to operator's level requirement, operator only need it is curved to required angle stopping pull Fixed handle 6.

As a kind of preferred structure of claw 7, the claw 7 includes stock and is fixed on three on stock and to be parallel to each other Root quarter butt, in three quarter butts two the same ends for being located at the stock and between be formed with the gap of clamping work piece 8, it is another Root is hinged on the handle 6.Such structure reduces equipment cost on the basis of structural reliability is able to satisfy requirement.

Pipe die 1 is shaped in as support wing plate 2 and a kind of preferred mounting structure of support shaft 3, the support wing plate 2 The back side, the both ends of the support shaft 3 are respectively welded on two support wing plates 2.Such structural reliability is higher.

The above specific structure and dimension data are illustrated to the preferred embodiment of the utility model, but this reality It is not limited to the specific embodiments with novel creation, those skilled in the art are in the premise without prejudice to the spirit of the present invention Various equivalent deformation or replacement can be also made down, these equivalent deformations or replacement are all contained in the claim of this application and are limited In fixed range.
