Abstract

The utility model relates to a steel bar straightening machine. A rotating shaft driven by a transmission mechanism is connected with a frame; the rotating shaft is superposed with the returning center of the frame. The frame is connected with a soleplate provided with a roller through a group of adjusting elements; a group of rollers are orderly distributed at the two sides of the returning center of the frame; the rotating shafts of the rollers are fixed on a support connected with the soleplate. The steel bar straightening machine of the utility model does not bear excessive pressing force so as to guarantee the straightening without breaking.

Description

Bar straightener

The utility model relates generally to a kind of alignment machinery of wire rod, particularly a kind of bar straightener.

The general employing of known bar straightening machine organized rolls more, every group of pressure roller installed side by side, the pressure roller rotation drives reinforcing bar reaches straightening by the gap between per two rolls requirement, but the cost of manufacture height of common this device, break easily when especially reinforcing bar is by roll, therefore the use of this device is not handy, makes us very satisfied, and it is necessary therefore improving.

The purpose of this utility model then is to provide a kind of bar straightener that can overcome the shortcoming of prior art.

For achieving the above object, scheme of the present utility model is: the rotating shaft that transmission mechanism drove links to each other with a framework, rotating shaft overlaps with the centre of gyration of framework, framework is adjusted element by one group and is joined with the base plate that roll is installed, one group of centre of gyration both sides that are distributed in framework that roll is orderly, the rotating shaft of roll is fixed on the bearing that joins with base plate.

Adopt such scheme, reinforcing bar moves along the centre of gyration of device, is not subjected to excessive pressure rolling power, thereby can guarantee straightening and can not break, and has overcome the defective of prior art and has realized the purpose of this utility model.

Below in conjunction with diagram and the real example of dragging scheme is described in more detail.

Fig. 1 is the front view of bar straightener;

Fig. 2 is the A-A view of master map;

Fig. 3 is the B-B view of Fig. 1.

Fig. 4 is the fundamental diagram of bar straightener.

Bar straightener as shown in Figure 1; give belt pulley (1) by power set with transmission of power; with belt pulley (1) join for the porose rotating shaft (2) in center; the flange of rotating shaft (2) is connected with a rectangular frame (3); the another side of framework (3) links to each other with another flanged (FLGD) rotating shaft (4); two rotating shafts (2) and (4) are supported by one group of bearing block (5); and the centre of gyration of formation framework (3); framework (3) is not drilled with the hole with the appropriate location on both sides in addition that rotating shaft (2) links to each other with (4); the every limit of present embodiment is drilled with three holes; a screw rod (6) is passed in each hole; screw rod (6) is gone up an inside and outside nut (7) the conduct adjustment link that is with respectively in the hole; end of screw rod (6) and a base plate (8) welding; base plate (8) upper edge center line is distributed with one group of roll (9); as shown in Figure 2; roll (9) supports by roller support (10); its structure is that a screw rod (11) passes hole on the roll and the hole on the bearing (10); an end tightens up with nut then; the head of screw rod (11) is interior hexagonal; as shown in Figure 2; the another side of rectangular frame (3) by another group roll of same support structure as shown in Figure 3; but the incline direction difference of every group of roll; roll is imagined as its helix of composition that distributes; helix angle is 25 °; can certainly get other different angles, but all under the protection of present patent application.As shown in Figure 4, therefore from installation diagram 1, can find out that two groups of rolls are interspersed, rather than the pairing of prior art distributes.

Operation principle of the present utility model is as described below, when the reinforcing bar for the treatment of straightening (12) is entered the gap of being made up of roll by the axle centre bore, the helix of the framework (3) of rotation and two groups of roll compositions is equivalent to a nut that helix is arranged, though nut can rotate but can not move, so becoming threaded rod, reinforcing bar moved forward by drive, in this process and obtain straightening, in the process of straightening owing to be not subjected to excessive extruding, so the reinforcing bar that can not fracture.Because operation principle is different with the straightener of prior art, so roll can not require to accomplish that enough rigidity will be arranged that frame does not require to have very high rigidity yet, so installation cost dwindles greatly.In use need not the very important person and draw reinforcing bar in the front, alleviated user's labour intensity, spue automatically, efficient improves greatly, benefits from welcome deeply.

In sum, the utility model is successful.
