Abstract

The utility model relates to a pipe fitting machining tool technical field, specifically speaking relates to a hydraulic brake pipe shaping wrench of bending. The wrench comprises a wrench framework, a positioning pin and a bending bearing, wherein the wrench framework comprises a wrench handle and a wrench head, and a stepped design is adopted between the wrench handle and the wrench head; the wrench head is provided with an oval bending slotted hole, the positioning pin is welded on the wrench head on the front side of the oval bending slotted hole by adopting carbon dioxide gas shielded welding, and the bending bearing is assembled at the oval bending slotted hole through a bolt and is locked and fixed through a fastening nut. The utility model utilizes the lever principle, prolongs the force arm, and simultaneously adopts the bending bearing to bend the pipe body, so that the pipe bending operation is more light and labor-saving, the labor intensity of workers is greatly reduced, and the working efficiency is improved; and moreover, the size deviation of the radius of the arc at the bent part is reduced, and the quality of the product is ensured.

Description

Hydraulic brake pipe forming bending wrench

Technical Field

The utility model relates to a pipe fitting machining tool technical field, specifically speaking relates to a hydraulic brake pipe shaping wrench of bending.

Background

The hydraulic brake pipe is an important component of an automobile hydraulic brake system, a pipe body needs to be bent according to production requirements in the machining and forming process, the pipe body is bent manually in the original bending mode, the labor intensity of workers is high, the production efficiency is low, the size deviation of the arc radius of the bending part is large, and the product quality is uneven.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a hydraulic brake pipe shaping wrench of bending solves above technical problem.

In order to solve the above problems, the utility model adopts the following technical scheme:

a hydraulic brake pipe forming bending spanner comprises a spanner framework, a positioning pin and a bending bearing, wherein the spanner framework comprises a spanner handle and a spanner head, and a stepped design is adopted between the spanner handle and the spanner head; the wrench head is provided with an oval bending slotted hole, the positioning pin is welded on the wrench head on the front side of the oval bending slotted hole by adopting carbon dioxide gas shielded welding, and the bending bearing is assembled at the oval bending slotted hole through a bolt and is locked and fixed through a fastening nut.

Preferably: the wrench handle and the wrench head are of an integrated structure.

Has the advantages that: compared with the prior art, the utility model utilizes the lever principle, lengthens the force arm, and simultaneously adopts the bending bearing to bend the pipe body, so that the pipe bending operation is more convenient and labor-saving, the labor intensity of workers is greatly reduced, and the working efficiency is improved; and moreover, the size deviation of the radius of the arc at the bent part is reduced, and the quality of the product is ensured.

Drawings

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

fig. 2 is a schematic side view of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

Examples

Referring to fig. 1-2, the hydraulic brake pipe forming bending wrench described in this embodiment includes a wrench frame, a positioning pin 1 and a bending bearing 2, the wrench frame includes a wrench handle 3 and a wrench head 4 which are integrally formed, and a stepped design is adopted between the wrench handle 3 and the wrench head 4. The ladder design is adopted between wrench handle 3 and wrench head 4 of this embodiment, has lengthened wrench handle 3's length, and according to lever principle, the extension arm of force makes the return bend operation light laborsaving more.

The wrench head 4 is provided with an oval bending slotted hole 6, and the oval bending slotted hole 6 is formed by linear cutting processing. The positioning pin 1 is welded on a wrench head 4 on the front side of the oval bending slotted hole 6 through carbon dioxide gas shielded welding, and the bending bearing 2 is assembled at the oval bending slotted hole 6 through a bolt 5 and is locked and fixed through a fastening nut 7. According to the different pipe diameters of the pipe body to be bent, the fastening nut 7 can be unscrewed to adjust the position of the bending bearing 2 on the oval bending slotted hole 6.

When the bending device is used, the position of the bending bearing 2 on the oval bending slotted hole 6 is adjusted according to the pipe diameter of a pipe body to be bent, and the pipe body is locked and fixed through the fastening nut 7. Then fixing the positioning pin 1 on the working table surface, enabling the pipe body to be bent to penetrate through a gap between the positioning pin 1 and the bending bearing 2, and rotating the wrench handle 3 to bend the pipe body.

The utility model utilizes the lever principle, prolongs the force arm, and simultaneously adopts the bending bearing to bend the pipe body, so that the pipe bending operation is more light and labor-saving, the labor intensity of workers is greatly reduced, and the working efficiency is improved; and moreover, the size deviation of the radius of the arc at the bent part is reduced, and the quality of the product is ensured.

The above is only the embodiment of the present invention, not so limit on the other hand through the patent scope of the present invention, all utilize the equivalent structure made in the specification and the attached drawings, directly or indirectly apply to other related technical fields, all with the same principle within the patent protection scope of the present invention.
