A Pneumatic Hammer for Slag Removal

Abstract

The invention discloses a pneumatic hammer for removing slag and belongs to the field of pneumatic hammers. A pneumatic hammer with a slag removal package, including a cylinder, in which an air hammer rod is slidably arranged, and the upper end of the cylinder is connected with an exhaust block and an air intake block in turn, and the upper end of the cylinder is connected by a cylinder connecting block The exhaust block and the air intake block; also include an upper diaphragm, a movable diaphragm and a lower diaphragm fixedly arranged in the air intake block, and the air intake block, the upper diaphragm, the movable diaphragm, and the lower diaphragm , The exhaust block and the cylinder are provided with a air path for driving the air hammer rod to move upward, b air path and c air path for driving the air hammer rod to move downward, by opening and closing the b air path Realize the moving up and down of the movable diaphragm; the present invention combines rapid pressure relief and gas circuit conversion to perform reciprocating strikes, which can strike quickly, with high strike force, and can be quickly reset, while effectively avoiding the stuck phenomenon.

Description

technical field [0001] The invention relates to the technical field of air hammers, in particular to a pneumatic hammer for slag removal. Background technique [0002] Die castings generally have multiple slag pockets that need to be cut at the beginning, and there are connecting sections between adjacent slag pockets. Generally, these slag pockets need to be removed. The existing slag pocket removal methods generally include manually knocking off die castings Slag bag, use a punch to wash off the die-casting slag bag, and use a profiling frame to take out the slag bag. However, knocking off the die-casting slag bag manually is labor-intensive, low in labor efficiency, high in cost, unstable in quality, and deformed; [0003] In the prior art, the application number is 201721215175.X, and a slag removal charter machine was disclosed on 2018.07.03, including a frame, a knocking plate is arranged on the frame, and an air hammer is arranged on the upper side of the knocking pla...

AI Technical Summary

Problems solved by technology

The utility model is provided with when the die-casting parts to be knocked are placed on the knocking plate, the air hammer is controlled by the sensor and the air compressor, and then the die-casting parts are hit, and the manipulator is used to fix the die-casting parts, and the manipulator is used to fix the die-casting parts, and rotates with the fixed frame Connection, the fixed frame is connected with the manipulator through the damping shaft, and the position of the die-casting can be adjusted. The knocking plate is used to place the die-casting. Slag discharge is performed on the knocked-off slag bag, and at the same time, automatic knocking is performed. The knocking quality is stable and can effectively remove the slag bag, but there are still some defects. The air hammer uses a simple cylinder or piston to reciprocate. It is easy to get stuck during the striking process, the striking force is small, it is difficult to reset, and the slag on the product cannot be effectively removed

[0004] The application number in the prior art is 201810891889.5, and on 2018.10.26, an air hammer device of a dongdong machine in the technical field of slag knocking equipment was announced, including a valve head system, a valve body system and a valve stem system. The valve head system uses To control the intake and exhaust of the valve body, the valve body system is used to control the compression and work of the gas, and the valve stem system is used to realize the percussion work. The present invention uses reasonable intake, compression, The control of work and exhaust, while using the up and down movement of the puller in the puller chamber, can easily drive the push rod to move up and down to realize the work of knocking out the slag bag, but there are still certain defects. Only the opening of the puller in the valve body is used. The reciprocating movement is achieved by closing and closing, and the overall movement is carried out by increasing the pressure in one direction through the conduction of the paddle. There is no combination of rapid pressure relief and air path conversion for the cylinder to strike. One direction requires higher pressure, and the air hammer exists. It is easy to get stuck during the striking process, the striking force is small, it is difficult to reset, and the slag on the product cannot be effectively removed
