Full cylinder riding rail type pneumatic saw

Abstract

The invention discloses a full cylinder riding rail type pneumatic saw which comprises a moving cutting mechanism and a pneumatic clamping mechanism which is arranged below the moving cutting mechanism and used for clamping metal materials. The moving cutting mechanism comprises a reciprocating cylinder and a lifting cylinder. The reciprocating cylinder is fixedly arranged on a saw beam, a piston rod of the reciprocating cylinder is connected with a knife holder and controls the knife holder to move back and forth on a guide rail of the saw beam, and a cutting saw strip is arranged at the bottom end of the knife holder. The lifting cylinder is connected with the saw beam through a connecting rod connected in a hinged mode, and up-and-down lifting of the saw beam is achieved through the lifting cylinder. The lifting cylinder and the reciprocating cylinder are matched with each other to complete the process of 'downward-forward saw cutting-upward lifting-backward quick returning and retracting' of the knife holder. The pneumatic clamping mechanism further comprises a clamping cylinder fixedly arranged on a bottom seat. The bottom seat is designed in a riding rail type and can be fixedly arranged on a rail. The clamping cylinder controls a moving sliding block along a clamp bottom seat to slide toward the middle through the fact that a gear and a rack are meshed to drive, and therefore workpieces are clamped. The full cylinder riding rail type pneumatic saw is simple in operation, low in noise, stable in performance, high in cutting efficiency, safe and reliable and has wide using value.

Description

technical field [0001] The invention relates to the technical field of metal processing machinery, in particular to a rail-riding full-cylinder pneumatic saw and its pneumatic system. Background technique [0002] In recent years, with the continuous development of the coal mine industry, safety and efficiency have become the primary factors in the mining industry. It is reported that metal materials such as loaders and scraper conveyor chains in coal mines are prone to cracks due to high loads, and they need to be replaced as soon as possible due to production safety. [0003] At present, domestic mines generally use manual manual sawing, which is time-consuming and laborious. At present, electric saws on the market mainly include circular sawing machines and bow sawing machines. Although circular sawing machines have high cutting efficiency, their circular saw blades wear a lot and have a short service life. The saw blades need to be ...

[0003] At present, domestic mines generally use manual sawing, which is time-consuming and laborious.

At present, electric saws on the market mainly include circular sawing machines and bow sawing machines. Although circular sawing machines have high cutting efficiency, their circular saw blades wear a lot and have a short service life. The saw blades need to be replaced frequently, and the reliability is poor; , due to the use of hydraulic system control, the machining accuracy of parts such as control valves is very high, and most bow sawing machines use crank linkage mechanisms, so in order to realize reciprocating motion, real-time motion of knife feeding and lifting, the structure of its control part is relatively complex

Although the existing pneumatic reciprocating saws with gas as the power source have a simple structure and rely on the cylinder to directly drive the reciprocating cutting, they cannot realize the automatic feeding of the knife and saw. They all rely on manual pressure. Low cutting efficiency
