Abstract

The invention relates to a bending die tool for metal thin-wall pipelines and belongs to the technical field of thin-wall pipe bending application. According to the bending die tool for the metal thin-wall pipelines, a rotary fixture is arranged on a base through a rotary shaft, matched screw threads are arranged between a rotary fastening handle and a handle fixing rack, and the base is also provided with a pipe casing core support rack for fixing a pipe casing core. The rotary fixture can be rotated leftward and rightward to complete pipe bending at various angles, and the maximum bending angle can reach 180 degrees. A pipe can not be fractured or shrunken when being bended by the die tool, the operation is simple, the production efficiency is high, the cost is saved, and the bending die tool is mainly used for bending thin-wall pipes.

Description

The Bending Mould frock of metal thin-wall pipeline

Technical field

The present invention relates to a kind of Bending Mould frock of metal thin-wall pipeline, belong to light-wall pipe bend pipe applied technical field.

Background technology

The Bending Mould frock of metal thin-wall pipeline is a portable mold frock.Common bending method is with the sub-bending of can fine sand after the pipe heating.Error is large, and technique is loaded down with trivial details, expends man-hour, and cost of manufacture is high.

Summary of the invention

In order to overcome above-mentioned problems of the prior art, the invention provides a kind of Bending Mould frock of metal thin-wall pipeline, this mold tooling should be simple in structure, and is easy to use, guarantees crudy.

Common bending method is with the sub-bending of can fine sand after the pipe heating.Error is large, and technique is loaded down with trivial details, expends man-hour, and the problem of cost of manufacture the invention provides a kind of Bending Mould frock of metal thin-wall pipeline.

The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of Bending Mould frock of metal thin-wall pipeline, it comprises a rolling clamp, described rolling clamp adopts a rotating shaft that rotating bottom board is arranged on the base, fix the axial anchor clamps of pipe and a handle fixed mount at rotating bottom board, rotate between fastening handle and the handle fixed mount and be provided with matching thread, the end that rotates fastening handle connects a pipe rotating clamp; On base, also be provided with the fixedly pipe box core bracing frame of pipe box core.

The axial anchor clamps of described pipe are provided with the arc groove that matches with pipe fitting at the end that rotating shaft is installed.

Be provided be used to the arc groove of clamping pipe fitting between described pipe rotating clamp and the axial anchor clamps of pipe.

The fastening handle of described rotation by rolling clamp around rotating shaft left or to right rotation.

The invention has the beneficial effects as follows: the Bending Mould frock of this metal thin-wall pipeline adopts rotating shaft that rolling clamp is arranged on the base, rotate between fastening handle and the handle fixed mount and be provided with matching thread, on base, also be provided with the fixedly pipe box core bracing frame of pipe box core.Rolling clamp can rotate to the left or to the right, finishes the bend pipe work of various angles, and maximum bends angle can reach 180o.This mold tooling bend pipe does not rupture, not flat pipe, and simple to operate, production efficiency is high, saves cost, is mainly used in the light-wall pipe bend pipe.

Fig. 2 is a kind of side view of metal thin-wall pipeline bending tool.

Fig. 3 is a kind of three-dimensional view of bending tool of metal thin-wall pipeline.

Among the figure: 1, rotate fastening handle, 2, the handle fixed mount, 3, rotating bottom board, 4, the pipe rotating clamp, 5, manage axial anchor clamps, 6, base, 7, the pipe box core, 8, pipe box core bracing frame, 9, rotating shaft, 10, arc groove.

The specific embodiment

Fig. 1,2,3 shows a kind of structure chart of Bending Mould frock of metal thin-wall pipeline.Among the figure, the Bending Mould frock of metal thin-wall pipeline comprises a rolling clamp, rolling clamp adopts rotating shaft 9 that rotating bottom board 3 is installed on the base 6, fixed tubular axle is to anchor clamps 5 and handle fixed mount 2 on rotating bottom board 3, rotate between fastening handle 1 and the handle fixed mount 2 and be provided with matching thread, rotate the end tube connector rotating clamp 4 of fastening handle 1, manage axial anchor clamps 5 and be provided with the arc groove that matches with pipe fitting at the end that rotating shaft 9 is installed, be provided be used to the arc groove 10 of clamping pipe fitting between pipe rotating clamp 4 and the axial anchor clamps 5 of pipe.On base 6, also be provided with the fixedly pipe box core bracing frame 8 of pipe box core 7.Rotating fastening handle 1 allows rolling clamp center on rotating shaft 9 to rotate to the left or to the right.

When carrying out the bend pipe operation, at first rotating fastening handle 1 90-degree rotation angle to the right, the head of pipe fitting is enclosed within on the pipe box core 7, pipe shaft places between pipe rotating clamp 4 and the axial anchor clamps 5 of pipe, rotate the fastening handle 1 of rotation, allow pipe rotating clamp 4 and the axial anchor clamps 5 of pipe clamp pipe shaft, then pull the fastening handle 1 of rotation and allow whole rolling clamp turn left around rotating shaft 9, just can be bent into the angle that needs to pipe fitting.Maximum bends angle can reach 180o.
