Abstract
The invention relates to a pipeline diameter diminishing device, which consists of a cold-drawing mould assembly, a jacking block, a slide block and a connection rod, wherein the slide block is fixedly connected with the connection rod, and the head part of the jacking block is matched with the internal transitional radian of the cold-drawing mould assembly. By adopting the steel pipe diameter diminishing device, a cold drawing machine directly draws the connection rod to pass through the cold-drawing mould assembly and the slide block, and with the force which is applied by the jacking block, the diameter of the steel pipe is easily reduced to be the required steel pipe, so the steel pipe is free from welding before the diameter diminishing, and the multi-time drawing and formation of the steel pipe caused by the infirm welding can be prevented.
Description
Technical field
The present invention relates to a kind of pipeline diameter diminishing device, a kind of large-diameter steel pipe that makes of saying so more specifically becomes the device of small-caliber steel pipe.
Background technology
At present, thereby adopting drawbench to change the footpath by the drawing of undergauge mould, steel mill's production small-caliber steel pipe large-diameter steel pipe commonly used becomes small-caliber steel pipe, need before the drawing at large-diameter steel pipe front end welding drawing head, treat that drawbench fixes the drawing head of welding, start drawbench and carry out reducing, treating that drawing finishes needs the drawing head to its head welding to cut, thereby finishing small-caliber steel pipe makes, its process such as not prison welding cause the drawing head to drop, then need welding again, and its drawing finishes and needs to cut its head, wastes time and energy; When especially producing stainless-steel pipe, it welds easily unlike cast iron materials, and Welding Structure is not firm, causes the drawing reducing to need repeatedly just can finish, and this device is inapplicable to the stainless steel pipe undergauge.
Summary of the invention
The purpose of this invention is to provide a kind of pipeline diameter diminishing device, the undergauge of the steel pipe simply and easily device of applicable various pipe fitting reducings.
A kind of pipeline diameter diminishing device of the present invention, it is by cold drawing die group 2, jacking block 4, slide block 5, connecting rod 6 is formed, and it is characterized in that: slide block 5 is fixedlyed connected with connecting rod 6, and jacking block 4 its heads and cold drawing die group 2 interior transition radians match.
Adopt a kind of pipeline diameter diminishing device provided by the invention, the power that the direct drawing connecting rod 6 of drawbench brings by jacking block 4 by cold drawing die group 2 and slide block 5 can make steel pipe easily undergauge be required steel pipe, thereby need not before the undergauge steel pipe to be welded, avoided not prison welding to cause steel pipe to need repeatedly drawing moulding.
Description of drawings
Fig. 1 is original pipeline diameter diminishing device structure chart.
Fig. 2 is a kind of pipeline diameter diminishing device structure chart of the present invention.
Among the figure, 1 is drawing head, cold drawing die group 2, steel pipe 3, jacking block 4, slide block 5, connecting rod 6.
The specific embodiment
The present invention will be described below in conjunction with Fig. 2:
A kind of pipeline diameter diminishing device of the present invention, it is by cold drawing die group 2, jacking block 4, slide block 5, connecting rod 6 is formed, and slide block 5 is fixedlyed connected with connecting rod 6, and jacking block 4 its heads and cold drawing die group 2 interior transition radians match.During drawing, drawbench and connecting rod 6 are formed fixing, and connecting rod 6 drives slide block 5 and gives jacking block thrust, make steel pipe 3 and cold drawing die group 2 interact, thereby finish cold-drawn.
Claims (2)
1. pipeline diameter diminishing device, it is by cold drawing die group (2), jacking block (4), slide block (5), connecting rod (6) forms, and it is characterized in that: slide block (5) is fixedlyed connected with connecting rod (6).
2. a kind of pipeline diameter diminishing device according to claim 1 is characterized in that: its head of jacking block (4) and the interior transition radian of cold drawing die group (2) match.
