Abstract
The invention provides a damping and denoising air hammer. The conventional air hammer has the defects of high noise, high vibration and large damages to walls of equipment in a hammering process. The damping and denoising air hammer comprises a shell (1), wherein the upper end of the shell is connected with an air inlet cover (2); the lower end of the shell is connected with a back substrate (3); an impact piston (4) is arranged inside the shell; the upper end of the impact piston absorbs a magnetic substrate (5) through electromagnetic force; the back substrate is provided with an exhaust opening (6); and the outer end of the back substrate is provided with a rubber pad (7). The damping and denoising air hammer is taken as a forging machine.
Description
Technical field
The present invention relates to a kind of pneumatic hammer, be specifically related to a kind of damping noise reduction pneumatic hammer.
Background technology
Pneumatic hammer generally refers to forge with machinery in the metal fever processing, and the with good grounds capacity of water that forges has plurality of specifications; Existing pneumatic hammer is by fuselage and be installed in interior compression cylinder, working cylinder, and control valve, and the tup and the anvil on the fuselage that are installed on the working cylinder piston form; Motor drives compression cylinder work by belt pulley, the output squeezing air, and by the action of control valve control working cylinder, the piston driving tup was mentioned when compressed air entered the working cylinder bottom when control valve, and when entering cylinder top, tup presses down; When forging the position, can be by riding moving up and down of control working cylinder, with the effect that obtains tip-tap and forge continuously.Noise is large in the process that existing pneumatic hammer beats, and vibrations are large, and are larger to the infringement of equipment wall.
Summary of the invention
The objective of the invention is provides a kind of damping noise reduction pneumatic hammer for the problem of above-mentioned existence, and the vibrations of beaing are little, and noise is little, and is little to the infringement of equipment wall.
Above-mentioned purpose is achieved through the following technical solutions:
The damping noise reduction pneumatic hammer, comprise: housing, described housing upper end connects Intake Cover, the lower end connects metacoxal plate, described enclosure interior is provided with impact piston, described impact piston upper end has steam vent by electromagnetic force adsorption magnetic force substrate on the described metacoxal plate, and the outer end of described metacoxal plate has rubber blanket.
Described damping noise reduction pneumatic hammer, described impact piston lower end is provided with Compress Spring.
Beneficial effect:
1. the present invention has increased rubber blanket in the outer end of metacoxal plate, and to the infringement of equipment wall, and noise is little in the process that can effectively avoid beaing.
2. the present invention is simple in structure easy to use, impact is large, can effectively solve the situations such as the sticking wall of powder material, bridging, obstruction, bridge formation, impulsive force is large, and noise is little, and Multiple Type is available, impulsive force and actuation time can be controlled, easy for installation, can in the environment such as explosion-proof, many dust, humidity, use, be widely used in the industries such as chemical fertilizer, chemical industry, food, medical treatment, agricultural chemicals, glass, cement.
3. the present invention makes processing simply, and easy to operate, result of use is good, less investment, instant effect.
Description of drawings
Fig. 1, structural representation of the present invention.
Among the figure: 1, housing, 2, Intake Cover, 3, metacoxal plate, 4, impact piston, 5, the magnetic force substrate, 6, steam vent, 7, rubber blanket, 8, Compress Spring.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Embodiment 1:
As shown in Figure 1: damping noise reduction pneumatic hammer of the present invention, comprise housing 1, described housing upper end connects Intake Cover 2, the lower end connects metacoxal plate 3, described enclosure interior is provided with impact piston 4, described impact piston upper end has steam vent 6 by electromagnetic force adsorption magnetic force substrate 5 on the described metacoxal plate, the outer end of described metacoxal plate has rubber blanket 7.The setting of rubber blanket is played well protective effect to the wall of equipment, has effectively reduced simultaneously noise.
Embodiment 2:
Described damping noise reduction pneumatic hammer, described impact piston lower end is provided with Compress Spring 8.
The course of work:
Do not pass at pneumatic hammer under the state of compressed air (3-7kg/cm2), magnetic piston is close on the substrate of hammer body rear end by strong magnetic force.When magnetic valve was switched on, compressed air flowed into the pneumatic hammer body, and its body internal pressure is increased.When pressure during greater than magnetic force, magnetic piston breaks away from a high speed substrate, drives the tup high-speed impact hammer body front end substrate on the piston, and its impulsive force is passed to feed bin, shoots down the dust that adheres on the feed bin; When magnetic valve stopped to switch on, compressed air was discharged, and by the effect of return spring, the magnetic piston rising is near the rear end substrate, was closely contacted on by magnetic force and was returned to reset condition on the substrate, waited for unlatching next time.
By above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.Unaccomplished matter of the present invention belongs to those skilled in the art's common practise.
Claims (2)
1. damping noise reduction pneumatic hammer, comprise: housing, it is characterized in that: described housing upper end connects Intake Cover, the lower end connects metacoxal plate, described enclosure interior is provided with impact piston, described impact piston upper end has steam vent by electromagnetic force adsorption magnetic force substrate on the described metacoxal plate, and the outer end of described metacoxal plate has rubber blanket.
2. damping noise reduction pneumatic hammer according to claim 1, it is characterized in that: described impact piston lower end is provided with Compress Spring.
