Abstract
The utility model provides a diameter reduction device for steel pipes. The device comprise a cold-drawing mould group, a top block, a slide block and a connecting bar, wherein, the slide block and the connecting bar are in fixed connection; and the head part of the top block is matched with the transitional radian in the cold-drawing mould group. Adopting the diameter reduction device provided by the utility model, a cold-drawing machine can draw the connecting bar; and the force of the cold drawing mould group and the slide block exerted through the top block enables the diameter of a steel pipe to be reduced to a required standard. Therefore, the steel pipe needs not to be welded before diameter reduction; and repeated drawing formation of the steel pipe caused by infirm welding is avoided.
Description
Technical field
The utility model relates to a kind of undergauge device, and 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.
The utility model content
The purpose of this utility model provides a kind of drawing head that need not, the undergauge of the steel pipe simply and easily device of applicable various pipe fitting reducings.
The utility model steel pipe undergauge device, it is by the cold drawing die group, jacking block, slide block, connecting rod is formed, and it is characterized in that: slide block is fixedlyed connected with connecting rod, and the interior transition radian of its head of jacking block and cold drawing die group matches.
The steel pipe undergauge device that adopts the utility model to provide, the power that the direct drawing connecting rod of drawbench brings by jacking block by cold drawing die group and slide block 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 steel pipe undergauge structure drawing of device.
Fig. 2 is the utility model steel pipe undergauge structure drawing of device.
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
Below in conjunction with Fig. 2 the utility model is described:
The utility model steel pipe undergauge device, 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, steel pipe undergauge device, 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).
2, steel pipe undergauge 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
