Abstract

The utility model relates to a wire stock straightening device. In order to obtain a wire stock straightening device which has the advantages of convenience, safety and economy, the utility model discloses a wire stock straightening machine with oblique rollers which comprises a prime mover, a transmission mechanism, a machine frame, a rotatable framework in the machine frame, side plates on both sides of a rotating central line in the machine frame, elastic component parts among the two side plates and the edge of the framework, and a plurality of rollers ranged in two rows on the inner surfaces of the two side plates; the two rows of rollers are mutually sloped, and all the axial line of the rollers are sloped towards the rotating central line of the framework. The utility model is widely suitable for being used in the positions, such as building sites, factories for prefabricated parts, etc. to straighten steel bars in various circular degrees and in various materials, and the utility model is especially suitable for straightening cold rolled ribbed steel bars.

Description

Cross roll formula wire-straightening machine

The utility model relates to a kind of wire rod equipment for straightening.

The aligning wire rod is an important operation of construction site and prefabricated component factory, and its common practice is: an end of wire rod is fixed, and at other end hoist engine, automobile or other external force are stretching with wire rod, and its weak point is: 1, enough big place must be arranged; 2, must prevent constantly that wire rod from collapsing to hurt sb.'s feelings; 3, investment is high, and power consumption is high, the labour intensity height, but work efficiency is not high.

The purpose of this utility model is to overcome the weak point in the above-mentioned background technology and a kind of cross roll formula wire-straightening machine is provided, this machine is widely used in construction site, prefabricated component factory etc. and locates, to align the reinforcing bar of various circularity, various materials, " cold-rolled ribbed " reinforcing bar particularly.

The purpose of this utility model reaches by taking following technical proposals:

1, do not have prime mover 1, transmission mechanism and frame 3;

2, on frame 3, by bearing and the front axle 2 of axially extending bore is arranged and rear axle 8 is installed the framework 4 that can rotate in frame 3; Front axle 2 and rear axle 8 are separately fixed on the edge at framework 4 rotation centerline two ends, and its axis all overlaps with framework 4 rotation centerlines; Front axle 2 is connected with transmission mechanism;

3, in the framework 4 of framework 4 rotation centerline both sides, respectively establish a side plate 5,9, biside plate is connected with the edge of several bolts 6 with framework 4 rotation centerline both sides respectively;

4, between the edge of side plate 5,9 and framework 4 rotation centerline both sides, establish several elastic parts 11 respectively;

5,, respectively establish roller 7, the two row rollers that several its axis all favour framework 4 rotation centerlines and tilt mutually at side plate 5,9 inner faces.

The utility model is compared background technology and is had following useful effect: 1, simple in structure, be easy to adjust and maintenance; 2, compact conformation, volume is little, and is in light weight, fixing wire rod not again, thus not limited by the place, even the operation that also can align wire rod at the flooring of construction; 3, safe and reliable, needn't worry that wire rod collapses and to hurt sb.'s feelings; 4, because wire rod is subjected to roll extrusion to a certain degree, its surface produces flow harden, can improve the mechanical performance of wire rod; 5, in roll extrusion, can make the wire rod rust cleaning; 6, investment is low, and energy consumption is low, and labour intensity is low, and the work efficiency height.

Description of drawings: Fig. 1, cross roll formula wire-straightening machine vertical view; Fig. 2, roller and wire rod relative motion figure.

The utility model is done further narration below in conjunction with the accompanying drawing illustrated embodiment:

After the start, framework 4 rotations, the roller group is along with framework 4 revolution, and behind roller contact wire rod, it just rotates, i.e. rotation.So the working condition of this machine is: wire rod 10 penetrates between first and third and second roller from the hole of front axle 2, be subjected to tentatively being aligned after the roll extrusion, and be brought between the 3rd, five and the 4th rollers, obtain aligning again, be brought into again between the 5th, seven and the 6th rollers ... at last, the wire rod that a velamen aligns fully that comes out from the hole of rear axle 8.

Gap between two row's rollers can be done the automatic adjustment of certain limit at work, but needs to adjust several bolts 6 in advance according to gauge or diameter of wire.Wear-resisting for the hole that makes front axle 2 and rear axle 8, can in the hole, load onto the part of similar wire drawing die respectively.
