Problems solved by technology

1. Hand-held light pneumatic saw: The saw has a simple structure and is easy to operate, but the speed is too fast, the vibration is large, the machining accuracy is poor, and the labor intensity of the workers will be increased at the same time
2. Pneumatic chain saw; the operation of this saw is very convenient, but the cutting object of this chain saw is mainly wood, and metal materials cannot be cut
3. Pneumatic circular saw: the biggest advantage of this saw is that it is very fast and easy to cut, but at the same time, due to the very fast speed of the impeller, it is easy to generate sparks and has poor safety
4. Mining hydraulic chain saw: This kind of saw has a large power, but it uses hydraulic oil as the medium, but it requires high processing precision of parts, easy to leak, and inconvenient to maintain

Embodiment 1

[0013] see figure 1 and figure 2 , a kind of pneumatic bow sawing machine provided by the present invention comprises a power mechanism 1, a power feed mechanism 2, a cutting mechanism 3, and a clamping mechanism 4 arranged below the cutting mechanism 3 for clamping metal materials; the power mechanism 1 includes an air motor 1b set on the frame 1a, one end of the air motor 1b is provided with a reducer 1c, the output shaft of the reducer 1c is matched with the crank 2a in the power feeding mechanism 2 through a key, and the other end of the crank 2a One end is hinged on the connecting rod I 2b, and the other end of the connecting rod I 2b is hinged with the knife rest 3a in the cutting mechanism 3, and the knife rest 3a is connected by a slide block 3b to realize reciprocating movement on the saw blade guide rail 3c, The bottom end of the knife rest 3a is equipped with a cutting saw blade 3d, and the knife rest 3a is driven by the air motor 1b to realize the reciprocating o...

Embodiment 2

[0015] This embodiment is an explanation of the pneumatic control mode of the present invention:

[0016] see image 3 , the pneumatic control system includes an air source 5, and the air source 5 is respectively connected to the air motor 1b provided with the air motor speed control switch 8 through the pressure reducing valve 16 and the air source switch 7 successively, and is realized by using the switching valve 9 On the switched cylinder control circuit, the cylinder control circuit includes a fast lifting valve 10 connected to the switching valve 9 and a stroke reversing valve 11. When the switching valve 9 is switched to the left position, the fast lifting valve 10 formed by the switching valve The lifting working circuit starts to work. When the switching valve 9 switches to the right position, the stroke reversing working circuit formed by the stroke reversing valve 11 starts to work; a one-way valve is connected to a circuit formed by the fast lifting valve 10 and th...

Abstract

The invention discloses a pneumatic hacksawing machine, which comprises a motive power mechanism, a motive power feeding mechanism, a cutting mechanism and a clamping mechanism, wherein the clamping mechanism is arranged under the cutting mechanism and is used for clamping metal materials, the motive power mechanism comprises a pneumatic motor, the pneumatic motor drives the cutting of the cutting mechanism through the motive power feeding mechanism consisting of a crank and a connecting rod, and in addition, pneumatic elements such as air cylinders are matched for realizing the movement tracks of falling, forward sawing, lifting and returning. A pneumatic system adopts the pneumatic motor and the air cylinders as executing elements, the matching with a mechanical transmission system is adopted, the knife feeding and knife lifting movement is realized, the reliability is high, a knife tool can be protected to the greatest degree by the hacksawing machine, the cutting materials are wide, the performance is stable, the use and the maintenance are convenient, and greater practical values are realized in the improvement and the popularization of the hacksawing machine.

Description

technical field [0001] The invention belongs to the technical field of metal processing machinery, and in particular relates to a pneumatic control system for a pneumatic bow sawing machine used for sawing metal materials. Background technique [0002] With the development of social economy and the continuous innovation of science and technology, the mining industry is developing rapidly, and safety and efficiency are the most important factors in mining production. It is understood that metal materials such as scraper conveyor chains in coal mines are subject to high loads and are prone to cracks. They need to be replaced as soon as possible during use. Currently, manual sawing is mainly used to move metal materials, which is time-consuming and laborious. [0003] The following power saws were retrieved from relevant domestic literature. 1. Hand-held light pneumatic saw: This saw has a simple structure and is easy to operate, but the speed is too fast, the vibration is lar...
