Description

A kind of rotary enlarging board of multistation

Technical field

The present invention relates to adapter enlarging technical field, more specifically, more particularly, to one kind realizes multistation using mould The rotary enlarging board of pipeline enlarging.

Background technology

Pipe fitting is applied extremely wide in daily productive life, in daily productive life, is socketed also more between pipe fitting Common, necessarily having one end between the pipe fitting of socket is narrow end, and one end is wide end, thus connecting after wide end is by narrow end fit Connect, and then the connection between pipe fitting or between pipe fitting and part, thus the length required for being expanded into.

Pipe-expanding machine is the common equipment of pipeline mouth of pipe processing and forming, has the characteristics that efficiency high, rhythm are fast, in processing and forming In widely use.The product connecting by pipe fitting typically will be needed to be attached using by way of socket, because this kind of pipeline exists It is just the consistent tubulose of integral radius after one-step forming, thus also need to carry out enlarging reprocessing to one end of pipeline further.Existing The enlarging flow process having the pipe-expanding machine in technology is first the mouth of pipe of pipeline to be socketed on pipe-expanding machine die head, thimble spreading die head Mold section thus the section tubular wall of the spreading mouth of pipe and die contacts, subsequently thimble is exited, die head subsequently restores to the original state, by workman Take off pipeline, and again will be socketed in mold section without die head spreading section tubular wall, then drive thimble spreading die head again Mold section, thus the section tubular wall of the spreading mouth of pipe and die contacts, so repeatedly until the tube wall of the mouth of pipe is in directly more all by spreading Big is cylindric.

China Patent No. cn201410230212.9, name is a kind of the special of Portable small-bore steel-plastics composite pipe pipe-expanding machine In profit, disclose following scheme: include hand-hydraulic mechanism and clamping device, steel-plastics composite pipe is fastened by clamping device, so Utilize hand-hydraulic mechanism drive ram afterwards, good using steel-plastics composite pipe ductility, the feature of imitative type punching press can be carried out, hydraulic pressure moves Push dynamic imitative type enlarging pressure head, realize expanding steel plastic compount pipe port according to the profile of imitative type pressure head.Although to a certain extent Improve the continuous ability to work of device, improve the efficiency of steel-plastics composite pipe installation, but postindustrial by imitative type punching press After pipeline enlarging, enlarging wall unevenness after its molding, residual stress is big, easily ruptures during follow-up UNICOM, with When, rely on the enlarging to pipeline for the hand-hydraulic mechanism realization, with the increase of its operations number, the precision after enlarging gradually drops Low, after its processing the concordance of part accuracy poor it is impossible to meet that required precision is high, the demand of production of mass.And, existing There is the pipe-expanding machine in technology can only realize the enlarging operation of single, need by mobile enlarging apparatus, or product is many to complete The enlarging task of task, needs more extra positioning additional lock, and the expanding cycle is long, inefficiency.Therefore, how Realize automatization's processing of multistation pipe-expanding machine, improve flaring precision and working (machining) efficiency, and to reduce hand labor intensity be one Technical problem urgently to be resolved hurrily.
