Abstract
The utility model belongs to the field of straightening technology for sections, such as tubes and bars, and especially relates to a lower roll elevating mechanism of a section-straightening machine. The lower roll elevating mechanism of the section-straightening machine is simple in structure, convenient for operation, safe and reliable. The lower roll elevating mechanism of the section-straightening machine comprises a pedestal and a lower roll seat disposed in the pedestal. A cylinder is disposed on the pedestal, a cylinder lever stretches into the pedestal for connecting with a push rod, which is connected with the lower roll seat, a matching sleeve is fixed on the lower roll seat through bolts, the push rod is disposed in the matching sleeve, shaft sleeves are disposed on the pedestal, and the lower roll seat is disposed in the shaft sleeves in a matched manner. The lower roll elevating mechanism has the advantages of being simple and functional in structure, safe and reliable and convenient for dismounting.
Description
Technical field
The utility model belongs to section steel straightening technical fields such as tubing, bar, particularly relates to a kind of lower roll elevating mechanism of simple in structure, easy to operate and safe and reliable section-straightening machine.
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 purpose of this utility model is to provide a kind of lower roll elevating mechanism of section-straightening machine, and it can solve the weak point that exists in the above-mentioned technology.
The technical scheme that realizes the utility model purpose is as follows:
The lower roll elevating mechanism of section-straightening machine, it comprises base, the lower roller base in base, base is provided with oil cylinder, the cylinder bar of oil cylinder stretches into and is connected with push rod in the base, push rod links to each other with lower roller base, is fixed with engage sleeves by screw on the lower roller base, and push rod is located in the engage sleeves, base is provided with axle sleeve, in lower roller base cooperation and the axle sleeve.
Be provided with limited block between described cylinder bar and the push rod, base is provided with plane bearing and matches with limited block.
Described base is provided with the positioning sleeve that is used to cooperate the cylinder bar.
Benefit of the present utility model is simple and practical, and is safe and reliable, the characteristics of convenient disassembly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the lower roll elevating mechanism of section-straightening machine, it comprises base 11, the lower roller base in base 11 1, base 11 is provided with oil cylinder 9, the cylinder bar 8 of oil cylinder 9 stretches into and is connected with push rod 5 in the base 11, push rod 5 links to each other with lower roller base 1, be fixed with engage sleeves 4 by screw 2 on the lower roller base 1, push rod 5 is located in the engage sleeves 4, base 11 is provided with axle sleeve 3, in lower roller base 1 cooperation and the axle sleeve 3, is provided with limited block 7 between cylinder bar 8 and the push rod 5, base 11 is provided with plane bearing 6 and matches with limited block 7, and base 11 is provided with the positioning sleeve 10 that is used to cooperate cylinder bar 8.
