Abstract
The utility model relates to a vertical elevation-type withdrawing and strengthening machine, which comprises a stander, wherein the top end of the stander is provided with a hydraulic cylinder, and the top end and the bottom end inside the stander are respectively provided with an upper roll assembling device and a lower roll assembling device. One side of the stander is provided with an upper roll drive device, and the upper roll drive device is connected with the upper roll assembling device. The vertical central line of the hydraulic cylinder and the vertical central line of the stander are overlapped with a normal of an arc casting blank. The vertical elevation-type withdrawing and strengthening machine has the beneficial effects that the structure is simple, and large straightening force needed by a large-cross-section casting blank can be guaranteed; the damage of component of the straightening force on the surface of the casting blank can be avoided; and convenience in disassembling, installation and maintenance can be realized, the production efficiency can be greatly improved, and the service life of the equipment can be prolonged.
Description
Technical field
The utility model relates to a kind of vertical lift type withdrawal straightening machine.
Background technology
At present, in large section square billet or round billet continuous casting production process, according to different section, steel grade, various forms of withdrawal straightening machines are arranged in actual applications, mainly comprise following several: dual 5-roller frames, eight roller monoblock types, pony roll footpath multi roll and independent jaw type etc.But have tangential component between existing above-mentioned each form withdrawal straightening machine straightening force and strand, straightening force is subjected to rack construction form restriction and can not be too large, exists and changes defectives such as safeguarding inconvenience.
The utility model content
The purpose of this utility model is to provide a kind of vertical lift type withdrawal straightening machine, adopt Driven by Hydraulic Cylinder to apply the normal direction straightening force, i.e. the relatively independent vertical direction application of force, and every pair of up-down rollers is provided with independently frame, carry out dismounting, mutually noninterfere when safeguarding, handled easily.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of vertical lift type withdrawal straightening machine comprises frame, and the top of described frame is provided with hydraulic cylinder, and top and the bottom of frame inside are respectively equipped with roll assembly device and lower roll assembly device; One side of described frame is provided with roll driving apparatus, and described upper roll driving apparatus is connected with upper roll assembly device.
Preferably, the vertical center line of the vertical center line of described hydraulic cylinder and frame all overlaps with arc strand normal.
The beneficial effects of the utility model are: simple in structure, can guarantee the large straightening force that realizes that large section casting blank is required; Avoided the damage of aligning component to casting billet surface; And easy disassembly, maintenance, greatly improved production efficiency, extended service life of equipment.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the front view of the described vertical lift type withdrawal straightening machine of the utility model embodiment;
Fig. 2 is the side view of the described vertical lift type withdrawal straightening machine of the utility model embodiment.
In figure:
1, hydraulic cylinder; 2, upper roll driving apparatus; 3, upper roll assembly device; 4, frame; 5, lower roll assembly device.
The specific embodiment
As shown in Fig. 1-2, the described a kind of vertical lift type withdrawal straightening machine of the utility model embodiment comprises frame 4, and the top of described frame 4 is provided with hydraulic cylinder 1, and top and the bottom of frame 4 inside are respectively equipped with roll assembly device 3 and lower roll assembly device 5.One side of described frame 4 is provided with roll driving apparatus 2, and upper roll driving apparatus 2 is connected with upper roll assembly device 3.The vertical center line of the vertical center line of described hydraulic cylinder 1 and frame 4 all overlaps with arc strand normal.
During work, the utility model integral installation is used for depressing roll assembly device 3 and produces straightening force on arcuate base, guarantees that simultaneously frame 4 vertical center lines overlap with installed position arc strand normal; Hydraulic cylinder 1 be installed on frame 4 directly over, axis overlaps with frame 4 vertical axis, guaranteed that the straightening force that hydraulic cylinder 1 applies overlaps with the direction of arc strand, has avoided aligning component to the damage of casting billet surface; Frame 4 can adopt Welding Structure, is subjected to force direction single, can bear larger vertical loads; Adopted every pair of upper roll assembly device 3, lower roll assembly device 5 to be assemblied in frame 4, each frame 4 assemblings all can be mutually without dismounting alone, maintenance interferingly relatively independently.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
