Abstract
The utility model discloses a kind of Hubei Province formula straightener, comprise the first lever arm, the second lever arm, the middle part of the middle part of the first lever arm and the second lever arm is hinged by pin joint, the rear end of the rear end of the first lever arm and the second lever arm is connected with hydraulic cylinder, and the front end of the front end of the first lever arm and the second lever arm forms Hubei Province formula pressure mouth.The length of the power arm of the first lever arm and the second lever arm is greater than the length of resistance arm.While axial workpiece being carried out to alignment by this Hubei Province formula pressure mouth, can amplify power by lever on the one hand, reduce the pressure of hydraulic cylinder itself, can cushion and reduce by lever on the other hand pressure and the stroke of hydraulic oil accumulation, greatly improved the precision of alignment.
Description
Technical field
The utility model relates to a kind of coalignment of axial workpiece, relates in particular to a kind of Hubei Province formula straightener.
Background technology
For axial workpiece, as post alive, the cylinder bar etc. of coal-mine hydraulic support, in use often there is bending, at this moment just need to carry out alignment to it.
In prior art, generally pass through hydraulic press directly to its crooked position pressurization alignment.
At least there is following shortcoming in above-mentioned prior art:
In alignment process, need pressure and the stroke of the pressure head of strictly controlling hydraulic press, current control technology is also easily accomplished, but, because hydraulic oil itself possesses certain decrement, therefore, in pressure process, can accumulate certain pressure and stroke, in the time that axial workpiece pressurized exceedes the yield limit of its material, the intensity of material can reduce suddenly, now, the release of the pressure accumulating in hydraulic oil and stroke meeting explosion, this burst size is uncontrollable, can cause axial workpiece pressurized excessive, greatly reduce the precision of alignment.
Summary of the invention
The purpose of this utility model is to provide Hubei Province formula straightener that a kind of alignment precision is high.
The purpose of this utility model is achieved through the following technical solutions:
Hubei Province of the present utility model formula straightener, comprise the first lever arm, the second lever arm, the middle part of the middle part of described the first lever arm and described the second lever arm is hinged by pin joint, the rear end of the rear end of described the first lever arm and described the second lever arm is connected with hydraulic cylinder, and the front end of the front end of described the first lever arm and described the second lever arm forms Hubei Province formula pressure mouth.
The technical scheme being provided by above-mentioned the utility model can be found out, Hubei Province formula straightener that the utility model embodiment provides, because the rear end of the rear end by the first lever arm and described the second lever arm is connected with hydraulic cylinder, the front end of the front end of the first lever arm and the second lever arm forms Hubei Province formula pressure mouth, while axial workpiece being carried out to alignment by this Hubei Province formula pressure mouth, can amplify power by lever on the one hand, reduce the pressure of hydraulic cylinder itself, can cushion and reduce by lever on the other hand pressure and the stroke of hydraulic oil accumulation, greatly improve the precision of alignment.

In figure: 1, the first lever arm, 2, the second lever arm, 3, hydraulic cylinder.
Detailed description of the invention
To be described in further detail the utility model embodiment below.
Hubei Province of the present utility model formula straightener, its preferably detailed description of the invention be:
Comprise the first lever arm, the second lever arm, the middle part of the middle part of described the first lever arm and described the second lever arm is hinged by pin joint, the rear end of the rear end of described the first lever arm and described the second lever arm is connected with hydraulic cylinder, and the front end of the front end of described the first lever arm and described the second lever arm forms Hubei Province formula pressure mouth.
The length of the power arm of described the first lever arm and described the second lever arm is greater than the length of resistance arm.
Specific embodiment one, as shown in Figure 1, described the first lever arm and described the second lever arm are through described pin joint arranged crosswise, and scissor-shaped is arranged.
Specific embodiment two, as shown in Figure 2, described the first lever arm and described the second lever arm are arranged in a side of described pin joint.
Hubei Province of the present utility model formula straightener, be connected with hydraulic cylinder by the rear end of the first lever arm and the rear end of the second lever arm, the front end of the front end of the first lever arm and the second lever arm forms Hubei Province formula pressure mouth, while axial workpiece being carried out to alignment by this Hubei Province formula pressure mouth, can amplify power by lever on the one hand, reduce the pressure of hydraulic cylinder itself, can cushion and reduce by lever on the other hand pressure and the stroke of hydraulic oil accumulation, greatly improved the precision of alignment.
The above; it is only preferably detailed description of the invention of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
