Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-4, a straightening roll 1 structure of a stretch bending straightening unit comprises a straightening roll 1, wherein bearing seats 2 are respectively installed at two ends of the straightening roll 1, specifically, lugs 6 are symmetrically fixed at two ends of the straightening roll 1, grooves 7 matched with the lugs 6 are formed in the inner sides of inner tiles of the bearing seats 2, and the straightening roll 1 is slidably installed in the grooves 7 through the lugs 6, so that the straightening roll 1 and the bearing seats 2 are installed.

The movable plates 8 are fixedly installed at the bottoms of the bearing seats 2 at the two ends through bolts, the sliding blocks 3 are fixed at the bottoms of the movable plates 8, the two-way screw rods 5 are installed on the internal threads of the two sliding blocks 3, each sliding block 3 corresponds to the threads on the two sides of the two-way screw rods 5 respectively, meanwhile, the sliding rails 4 are installed on the outer sides of the sliding blocks 3 in a sliding mode, and the bottoms of the sliding rails 4 are fixed in the rails on the lower frame body of the straightening machine.

Through the technical scheme, the handle 9 is further fixed at the end part of the bidirectional screw 5, thereby the bidirectional screw 5 is convenient to rotate, when the bidirectional screw 5 rotates, the bidirectional screw is in threaded fit with the sliding block 3 inside the sliding rail 4, the sliding block 3 slides in the sliding rail 4, thereby the sliding blocks 3 at two ends are close to or far away from each other, when the two sliding blocks 3 are far away from each other, the corresponding bearing seats 2 are driven to be close to or far away from each other, when the two bearing seats 2 are far away from each other, the grooves 7 in the bearing seats 2 are separated from the convex blocks 6 on the straightening rollers 1 and are gradually far away from each other until the two sliding blocks are completely separated from the straightening rollers 1, the straightening rollers 1 and the bearing seats 2 are disassembled, the disassembled straightening rollers 1 can fall on the sliding rail 4, the straightening rollers are supported by the sliding rail 4, when the assembling is carried out, the position of the straightening rollers 1 is adjusted, after the convex blocks 6 at two ends of the straightening rollers 1 are aligned with the grooves 7 on the bearing seats 2, the straightening rollers 1 are continuously controlled to be close to each other, so that the straightening rollers 1 and the straightening rollers are not required to be disassembled from the straightening machine, and the straightening machine is more convenient to be disassembled.

It is further to be supplemented that, in the above-mentioned scheme process, after the straightening roll 1 is detached from the bearing seat 2, the straightening roll 1 falls on the sliding rail 4 for supporting, and the following defects are not solved, firstly, when the straightening roll 1 is mounted on the bearing seat 2, the straightening roll 1 needs to be lifted to a position where the straightening roll 1 is raised from the bearing seat 2, the straightening roll 1 has a certain weight, which increases the labor intensity of an operator undoubtedly, therefore, the telescopic support rolls 10 are rotatably mounted between the two bearing seats 2, and the two support rolls 10 are both located at the front end and the rear end of the straightening roll 1 and abut against the support rolls, when the straightening roll 1 is rotated, the straightening roll 1 can be rotated on the two support rolls 10 without interfering with the straightening roll 1, and at the same time, when the straightening roll 1 is detached, the two ends of the straightening roll 1 and the bearing are always kept at the same height, there is no height, and when the straightening roll 1 is mounted again, the straightening roll 1 does not need to be lifted, which labor intensity of the operator is saved, and at the straightening roll 1 is convenient to rotate, and the straightening roll 1 and the support rolls are positioned at the same height of the grooves 6 and the grooves 7, and the support rolls 1 can prolong the service life of the straightening roll 1.

Specifically, constitute by two fixed rollers 11 and an regulation pole 13 at telescopic backing roll 10, wherein the one end of two fixed pipes is rotated and is installed on corresponding bearing frame 2, and the other end of fixed roller 11 is then seted up by regulation hole 12, adjust pole 13 then slidable mounting in the regulation hole 12 between two regulation rollers, when adjusting two bearing frame 2's position, drive the regulation hole 12 in the fixed roller 11 and slide on adjusting pole 13, realize holistic flexible, and neither influence normal installation and dismantlement also have the effect that backing roll 10 brought simultaneously.

When using, the slider 3 that drives both ends through two-way screw rod 5 is close to each other or keeps away from each other, and then drives the bearing frame 2 at both ends and is close to each other or keeps away from each other, makes bearing frame 2 and straightening roll 1 separation when both keep away from each other, realizes dismantling, then realizes on the contrary that it is more convenient to operate to the installation of straightening roll 1 and bearing frame 2.

The standard parts used in the application document can be purchased from the market, and can be customized according to the description of the specification and the description of the attached drawings, the specific connection mode of each part adopts conventional means such as mature bolts, rivets, welding and the like in the prior art, and machines, parts and equipment adopt conventional models in the prior art.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
