Abstract

The invention relates to a roller positioning device for the assembly of a seamless steel pipe sizing machine frame, which is characterized by comprising a center frame and three roller dies, wherein the three roller dies are semicircular tile-shaped and are connected with the center frame. Axes of the three roller dies are crossed pairwise; the three axes enclose an equilateral triangle; and the equilateral triangle is concentric with the center frame. The roller positioning device has the beneficial effects that the difficulty of whole machine assembly operation of the seamless steel pipe sizing machine frame can be reduced, and the work efficiency is improved.

Description

Sizing mill for seamless steel pipes frame assembling roll positioner
Technical field
The present invention relates to a kind of auxiliary assemble mechanism, is the roll positioner that uses when the sizing mill for seamless steel pipes frame is carried out the final assembly operation specifically.
Background technology
At present, in seamless steel pipe manufacturing field, a kind of equipment that all needs to use is the sizing mill for seamless steel pipes frame, and three rolls are arranged on this reducing mill stand usually.These rolls serious wearing and tearing can occur in long-term use procedure, according to certain life cycle, need to change operation to these rolls.Existing substitute mode is, directly the axle of roll extracted, and behind the roll that then more renews, axle loaded onto got final product again.Yet, in the final assembly operation of reducing mill stand, need first roll to be assemblied on the frame, and then locate other installing component with the border of roll, and the assembling of other installing component tends to cause roll to answer local pressure and occur rotating and have some setbacks, therefore, when final assembly, need the being dismounted for multiple times roll, and all need to debug behind each dismounting roll, so not only increase the difficulty of assembling work, and affected operating efficiency.
Summary of the invention
The problem to be solved in the present invention provides a kind of sizing mill for seamless steel pipes frame assembling and uses the roll positioner, adopts this device, can reduce the difficulty of sizing mill for seamless steel pipes frame final assembly operation, increases work efficiency.
For addressing the above problem, take following scheme:
Sizing mill for seamless steel pipes frame assembling of the present invention is to comprise centre frame and three roller dies with the characteristics of roll positioner, and three roller dies are semicircular tile, and they all link to each other with centre frame.The axis of described three roller dies intersects in twos, and three axis are encircled into equilateral triangle, and this equilateral triangle is concentric with described centre frame.
Take such scheme, have the following advantages:
Owing to be connected with three semicircular roller dies on the centre frame of sizing mill for seamless steel pipes frame assembling of the present invention with the roll positioner, therefore, when carrying out the assembling work of sizing mill for seamless steel pipes frame again, can first this device be placed on the shell of reducing mill stand, and make each roller die corresponding with the rigging position of holster shell topping roll, be equivalent to like this at this rigging position place roll has been installed, then after being with other installing component all to assemble, again this device is taken out, change roll and roll mandrel, and debug and get final product.Adopt this device to carry out the final assembly operation, only need carry out a roll assembling and Task of Debugging, its task difficulty reduces greatly, and operating efficiency is higher.
Description of drawings
Fig. 1 is the structural representation that the roll positioner is used in sizing mill for seamless steel pipes frame assembling of the present invention;
Fig. 2 be among Fig. 1 A-A to schematic diagram.
The specific embodiment
As depicted in figs. 1 and 2, sizing mill for seamless steel pipes frame assembling of the present invention comprises that with the roll positioner centre frame 1 and 2, three roller dies 2 of three roller dies are semicircular tile, and they all link to each other with centre frame 1.The axis of described three roller dies 2 intersects in twos, and three axis are encircled into equilateral triangle, and this equilateral triangle is concentric with described centre frame 1.
When implementing sizing mill for seamless steel pipes frame final assembly operation, first this device is placed on the shell of reducing mill stand, and make the circular arc of each roller die 2 Open Side Down the rigging position place that is buckled in the holster shell topping roll, be equivalent to like this at this rigging position place roll has been installed; Then, take the profile of roller die 2 as the location, assemble other installing component; After other installing component has all assembled, again this device is taken out, change roll and roll mandrel, and debug, can finish assembling work.
