A countersunk hole (2-1) is arranged on a reducing die holder (2) along the axial direction, and a tapered hole (3-1) and a through hole (3-2) are respectively arranged on a reducing die (3) along the same axial direction; the reducing die (3) is fixedly arranged in the countersunk hole (2-1) of the reducing die holder (2), and the axis of the reducing die holder (2) and the axis of the reducing die (3) are in the same straight line; the reducing die holder (2) is fixedly arranged at the end part of a piston rod (1) of a hydraulic cylinder, and a support (4) is arranged at one side of the reducing die (3); and a chuck (5) is fixedly arranged on the support (4), and the axis of the chuck (5) and the axis of the reducing die (3) are in the same straight line. The reducing device is suitable for contraction reducing of the boiler tube end.

Description

A kind of pipe end closing in diameter changing device
Technical field
The utility model relates to a kind of diameter changing device, is specifically related to a kind of pipe end closing in diameter changing device.
Background technology
In the high pressure boiler tube of 2.5MPa, for the actual process demand with boiler is installed, need part boiler pipe end be carried out reducing and handle, existing pipe end closing in reducing equipment not only cost is high, and the production cycle is long.
The utility model content
The purpose of the utility model is that not only cost is high in order to solve existing pipe end closing in reducing equipment, and long problem of production cycle, and then a kind of pipe end closing in diameter changing device is provided.
The technical scheme of the utility model is: a kind of pipe end closing in diameter changing device comprises hydraulic cylinder piston rod; Said diameter changing device also comprises reducing die holder, reducing mold, support and chuck, and the reducing die holder has counter sink along axis direction, and reducing mold has bellmouth and through hole along same axis direction; Reducing mold is packed in the counter sink of reducing die holder; And the axis of reducing die holder and the axis of reducing mold are on same straight line, and the reducing die holder is packed in the end of hydraulic cylinder piston rod, and support is arranged on a side of reducing mold; Chuck is packed on the support, and the axis of the axis of chuck and reducing mold is on same straight line.
The utility model compared with prior art has following effect: 1. the utility model is simple in structure, compact, and floor space is little, manufactures easily, and cost only needs about thousand yuan, as: make a required reducer pipe of 20 tons of boilers and can save 8,000 yuan to 10,000 yuan.2. the utility model need not heating, gets final product one-shot forming, has saved heating process and heating fuel, and each tube head only needed two minutes to get final product completion of processing, effectively raised operating efficiency, had shortened the production cycle.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The specific embodiment one: combine Fig. 1 that this embodiment is described; A kind of pipe end closing in diameter changing device of this embodiment comprises hydraulic cylinder piston rod 1; Said diameter changing device also comprises reducing die holder 2, reducing mold 3, support 4 and chuck 5, and reducing die holder 2 has counter sink 2-1 along axis direction, and reducing mold 3 has bellmouth 3-1 and through hole 3-2 along same axis direction; Reducing mold 3 is packed in the counter sink 2-1 of reducing die holder 2; And the axis of the axis of reducing die holder 2 and reducing mold 3 is on same straight line, and reducing die holder 2 is packed in the end of hydraulic cylinder piston rod 1, and support 4 is arranged on a side of reducing mold 3; Chuck 5 is packed on the support 4, and the axis of the axis of chuck 5 and reducing mold 3 is on same straight line.
Bellmouth 3-1 of this embodiment and through hole 3-2 can make according to the actual process demand.
The specific embodiment two: combine Fig. 1 that this embodiment is described, pass through bolt between reducing mold 3 of this embodiment and the reducing die holder 2.So be provided with, be convenient to dismounting.Other composition is identical with the specific embodiment one with annexation.
The use of the utility model is following:
At first, workpiece is packed in the chuck 5, and workpiece stretches out the suitable length of chuck 5; Then, primer fluid cylinder pressure, hydraulic cylinder drive hydraulic cylinder piston rod 1 to workpiece one lateral movement, when workpiece with after reducing mold 3 contacts, workpiece is extruded moulding, the pipe end closing in reducing of completion workpiece.
