Abstract
The utility model relates to an anti-extrusion device for a straightening roller carrier of a reinforcement bar straightening machine. The anti-extrusion device is mainly used for straightening reinforcement bars and comprises the straightening roller carrier and straightening wheels, wherein the straightening roller carrier comprises two mutually parallel transverse plates and two longitudinal plates; the anti-extrusion device is characterized in that threaded rods are further arranged; the threaded rods are positioned between two transverse plates and fixed on the transverse plates in a penetrating manner; center lines of the threaded rods are perpendicular to two transverse plates. The anti-extrusion device has the advantages that the structural design is reasonable, the strength is high, four threaded rods are used for pulling with nuts mutually in the center of the straightening roller carrier, so that the outward extruding tension of the straightening wheels can be effectively controlled during use, the straightening quality of the reinforcement bars is guaranteed, and meanwhile, the service life of the straightening machine is prolonged.
Description
Technical field
The utility model relates to a kind of bar straightener, a kind of anti-racking means of bar straightener straightening turning rolls particularly, and it mainly is applicable to the straightening of reinforcing bar, belongs to field of mechanical technique.
Background technology
In prior art, bar straightener is applied to the straightening of reinforcing bar, the straightening turning rolls is the critical piece of the bar straightening in straightener, the straightening wheel of different angles is installed in the straightening turning rolls, reinforcing bar extruding up and down by straightening wheel in the straightening process forms straight line, so straightening wheel has the tension force of outside extruding at work, this just needs the straightening turning rolls must possess anti-extrusion intensity.The structure of existing straightening turning rolls is seen Fig. 3-Fig. 4, it comprises transverse plate 10 and straightening wheel 11, in this straightening turning rolls, anti-racking means is arranged also, it is to be fixed on the transverse-roller frame of up and down with the iron plate 12 use bolts 13 about two 3mm, but the defective in using is: because iron plate 12 is to fix with cross bolts, at straightening wheel 11 outwards under the effect of extruding tension force, the fragile or fracture of bolt 13 directly affects service life of straightening turning rolls; Simultaneously, assembling inconvenience; Because the tension force of straightening turning rolls is large, just must increase the thickness of turning rolls if will ensure the quality of products, will increase production cost thus.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in prior art, and the anti-racking means of the bar straightener straightening turning rolls of a kind of reasonable in design, straightener long service life is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the anti-racking means of this bar straightener straightening turning rolls comprises straightening wheel and by two transverse plates, two straightening turning rolls that vertical plate forms, two transverse plates are parallel to each other, it is characterized in that also being provided with screw rod, described screw rod is between two transverse plates and pass two transverse plates and fix, and the center line of described screw rod is all vertical with two transverse plates.Make thus the utility model not be vulnerable in use the bending failure of tension force, when guaranteeing the bar straightening quality, extended the service life of straightener and straightening turning rolls; Simultaneously, the convenient and reliable assembly of straightener.
The utility model screw rod passes two transverse plates with nut or rivet or a kind of the fixing in welding.
Screw rod described in the utility model has four, and they are positioned at the middle part of straightening turning rolls; Anti-extrusion intensity is better thus, can more effectively control the outwards tension force of extruding of straightening wheel, extends the service life of straightener.
The utility model is all fixed with nut on the surfaces externally and internally of the transverse plate that described screw rod passes, and has guaranteed the working strength of screw rod and whole straightening turning rolls.
The utility model compared with prior art, have the following advantages and effect: reasonable in design, anti-extrusion intensity is high, at the middle part of straightening turning rolls with four screw rods and nut to drawing, can effectively control the outside extruding tension force of straightening wheel during use, when guaranteeing the bar straightening quality, extended the service life of straightener and straightening turning rolls; Simultaneously, the convenient and reliable assembly of straightener.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Fig. 3 is the partial structurtes schematic diagram of bar straightener in prior art.
Fig. 4 is that the B of Fig. 3 is to structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1-Fig. 2, the utility model is mainly by transverse plate 1, vertical plate 2, and straightening wheel 3, screw rod 6 and nut 7 form.In the present embodiment, transverse plate 1 and vertical plate 2 have respectively two, and two transverse plates 1 are parallel to each other, and two blocks of vertical plates 2 are parallel to each other; Screw rod 6 has four, and four screw rods 6 axially are being parallel to each other.
The utility model is welded and fixed by two transverse plates 1 and two blocks of vertical plates 2 and forms the straightening turning rolls; Fixedly spiral pin 5 penetrates transverse plate 1 and straightening wheel 3 and tightens fixingly, and straightening wheel 3 use bolts 4 are fixed on transverse plate 1, and fixedly spiral pin 5 snaps in transverse plate 1 just, makes the straightening wheel 3 can dystopy; Four screw rods 6 are between two transverse plates 1 and pass two transverse plates 1 in up and down, all tighten fixing with nut 7 at the surfaces externally and internally of two transverse plates 1; The center line 8 of screw rod 6 and nut 7 is all vertical with two transverse plates 1.In addition, screw rod 6 passes two transverse plates 1 except fixing with nut 7, also can be with in rivet or welding a kind of fixing.
During use, draw with four screw rods 6 and 7 pairs, nut at middle part at the straightening turning rolls, four screw rods 6 pass up and down transverse plate 1 its surfaces externally and internally and all tighten fixing with nut 7, this mounting structure forms longitudinal pulling force, when passing the straightening wheel 3 of different angles, reinforcing bar can form tension force, four screw rods 6 of cause and nut 7 are to be subjected to vertical extruding, screw rod 6 and nut 7 are not vulnerable to the bending failure of tension force, can effectively control thus the outwards tension force of extruding of straightening wheel 3, guarantee the straightening quality of reinforcing bar, and extend the service life of straightener.
Relevant " parallel " or terms such as " vertically " described herein, the slight error in its manufacturing or installation are to allow to exist.
Specific embodiment described in this specification, as long as the undeclared concrete shape of its part and size, this part can be any shape and size that adapt with its structure; Simultaneously, the part title of getting also can be different.All equivalence or simple change of doing according to the described structure of the utility model patent design, feature and principle are included in the protection domain of the utility model patent.
