Abstract
The utility model relates to a lower roller elevating device for a straightening machine, which comprises a base, an elevating screw installed on the base through a positioning sleeve, a planar bearing installed between the base and the shoulder part of the elevating screw, a gear motor installed on the elevating screw through a supporting semi-ring, an elevating screw nut matched with the elevating screw, a lower roller seat sleeved on the elevating screw nut, and a shaft sleeve arranged between the elevating screw nut and the lower roller seat. The lower roller elevating device is characterized in that safety set screws are respectively arranged at the both sides of the elevating screw at the lower end of the base, the upper end of the elevating screw nut is screwed with the lower roller seat through a screw, and the lower end of the elevating screw nut is fastened with the lower roller seat through a fastening screw. By adopting the structure, the lower roller seat is not directly contacted with the base during the descending process, thereby the phenomenon that the elevating screw nut is locked is avoided; the force applied to the elevating screw nut is evener, and the movement of the elevating screw and the elevating screw nut is more smooth, therefore, the structure is simple, the operation is convenient, secure and reliable; in addition, the lower roller elevating device also has the advantages of reasonable design and convenient installation and disassembly.
Description
Technical field
The utility model belongs to tubing, bar straightening technology field, particularly relates to a kind of simple in structure, easy to operate and safe and reliable straightener lower roll lowering or hoisting gear.
Background technology
Straightener lower roll lowering or hoisting gear is a critical component in the straightener of tubing, bar aligning, the reasonability of this device not only influences the realization of straightener function, and influence the flattening precision and the reliability of straightener, therefore, particularly important for the reliable and secure straightener lower roll lowering or hoisting gear of design one cover.At present, straightener lower roll lowering or hoisting gear adopts reducing motor to drive elevating screw usually, elevating screw passes to the lifting screw with power, the lifting screw drives the lower roller base lifting, because straightener produces very big straightening force in the aligning process, and the defective of lifting screw mounting structure, promptly only between lifting screw lower surface and lower roller base, locate, can not satisfy bigger straightening force like this, thereby cause whole lower roll lowering or hoisting gear to damage, cause very big influence to production; In addition, the lifting screw is that face contacts with base in the decline process, because contact area is big, causes the lifting screw locked easily when operation, causes whole lowering or hoisting gear stuck, and then makes whole straightener paralyse.
Summary of the invention
The utility model provides a kind of simple in structure, easy to operate and safe and reliable straightener lower roll lowering or hoisting gear for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of straightener lower roll lowering or hoisting gear, comprise base, the elevating screw of installing by positioning sleeve on the base, be installed in the plane bearing between base and the elevating screw shoulder, be installed in reducing motor on the elevating screw by supporting semi-ring, the lifting screw that cooperates with elevating screw, and be sleeved on lower roller base on the lifting screw, be provided with axle sleeve between lifting screw and the lower roller base, it is characterized in that: described both sides at base lower end elevating screw are provided with safe jackscrew, close by screw and lower roller base handle described lifting screw upper end, and lifting screw lower end is by marking closely screw and lower roller base is fastening.
The utility model can also adopt following technical measures:
Described lifting screw and lower roller base adopt matched in clearance.
Advantage and the good effect that the utlity model has are: owing to be provided with safe jackscrew between base and lower roller base, make lower roller base directly not contact with base in the decline process, avoid the lifting screw locked; Lifting screw upper end puts together on lower roller base by screw, lifting screw lower end is fastening by holding screw and lower roller base, adopt this structure can make the lifting screw stressed more even, and adopt matched in clearance between lifting screw and the lower roller base, make assembling easier, the motion of elevating screw and lifting screw is more smooth, so said structure is simple, easy to operate and safe and reliable, and the utility model also has advantages such as reasonable in design, easy installation and removal in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, lower roller base; 2, screw; 3, axle sleeve; 4, lifting screw; 5, elevating screw; 6, holding screw; 7, axle sleeve; 8, safe jackscrew; 9, reducing motor; 10, support semi-ring; 11, semi-ring; 12, positioning sleeve; 13, screw; 14, plane bearing; 15, base.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, on base 15, elevating screw 5 is installed by positioning sleeve 12, positioning sleeve 12 is fixed on the base 15 by semi-ring 11, between base 15 and elevating screw 5 shoulders, plane bearing 14 is installed by screw 13, the input of elevating screw 5 is installed reducing motor 9 by supporting semi-ring 10, lifting screw 4 is equipped with in elevating screw 5 cooperations, lower roller base 1 is sleeved on the lifting screw 4, lifting screw 4 adopts matched in clearance with lower roller base 1, axle sleeve 3 and axle sleeve 7 are installed between lifting screw 4 and the lower roller base 1, guarantee well motion between lower roller base 1 and the base 15, be provided with safe jackscrew 8 in the both sides of base 15 lower end elevating screws 5, make lower roller base 1 in the decline process, directly not contact, avoid lifting screw 4 locked with base 15; Close by 1 of screw 2 and lower roller base lifting screw 4 upper ends, and lifting screw 4 lower ends are fastening with lower roller base 1 by marking closely screw 6, guarantees that the lifting screw is stressed more even.Reducing motor 9 rotates and drives elevating screw 5 rotations like this, thereby drive lifting screw 4 and lower roller base 1 move up and down along axle sleeve 3, axle sleeve 7, thereby finishes the lifting of straightener lower roll.
Claims (2)
1. straightener lower roll lowering or hoisting gear, comprise base, the elevating screw of installing by positioning sleeve on the base, be installed in the plane bearing between base and the elevating screw shoulder, be installed in reducing motor on the elevating screw by supporting semi-ring, the lifting screw that cooperates with elevating screw, and be sleeved on lower roller base on the lifting screw, be provided with axle sleeve between lifting screw and the lower roller base, it is characterized in that: described both sides at base lower end elevating screw are provided with safe jackscrew, close by screw and lower roller base handle described lifting screw upper end, and lifting screw lower end is by marking closely screw and lower roller base is fastening.
