The air hammer comprises a motor, a reducer, a connection rod mechanism, a compression air cylinder, a working air cylinder and an anvil block; the output end of the motor is connected with the reducer; the reducer is connected to one end of the connection rod mechanism; the other end of the connection rod mechanism is connected with a piston rod of the compression air cylinder; the compression air cylinder is connected with the working air cylinder through a first air transmission pipe and a second air transmission pipe; the piston rod of the working air cylinder is provided with upper pressing iron; the anvil block is positioned below the upper pressing iron, and is provided with lower pressing iron; the air hammer also comprises a switching device which can switch compressed air between the compression air cylinder and the working air cylinder; and the switching device is arranged on the first air transmission pipe and the second air transmission pipe respectively. The air hammer can suspend, continuously hammer, and press a workpiece and can also hammer the workpiece once. The air hammer can fully process the workpiece.
Description
Technical field
The present invention relates to technical field of forging, be specifically related to a kind of pneumatic hammer.
Background technology
Existing pneumatic hammer generally is made up of parts such as motor, reductor, linkage, compression cylinder, working cylinder and anvil blocks; This pneumatic hammer is when work; Gas between compression cylinder and the working cylinder is controlled through the motor-driven linkage; Between compression cylinder and working cylinder, do not have a compressed-air actuated device of control, the cause air hammer can only be realized the action that single hits.
Summary of the invention
Multiple actions such as to above-mentioned technical problem, the present invention provides a kind of pneumatic hammer, and that pneumatic hammer of the present invention can be accomplished is outstanding, hit continuously, single hits and press down can be carried out many-sided processing to workpiece.The technical scheme that realizes the object of the invention is following:
Pneumatic hammer comprises motor, reductor, linkage, compression cylinder, working cylinder and anvil block, and the output of motor is connected with reductor; Reductor is connected with an end of linkage; The other end of linkage is connected with the piston rod of compression cylinder, and compression cylinder is connected with second appendix through first appendix with working cylinder, and the piston rod of working cylinder is provided with to iron; Anvil block is positioned under iron; Anvil block is provided with down and supports iron, also comprises the switching device shifter of a switching pressurized air between compression cylinder and working cylinder, and switching device shifter is separately positioned on first appendix and second appendix.
Adopted such scheme, when the present invention worked, motor came the piston in the drive compression cylinder through decelerator and linkage, and piston up-down is with the air in the compression cylinder.During piston up-down, compressed air alternately gets into the top or the bottom of working cylinder through rotary air valve, and the piston in the working cylinder is moved up and down together with the last iron that supports, and realizes the continuous strike to metal stock.Hammer the position of last two rotary air valves into shape through treadle or pull bar control air, tup is accomplished go up outstanding, hit continuously, action such as single hits and press down.
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is further described.
Description of drawings

Fig. 2 is a pneumatic hammer structure diagram of the present invention;
1 for treadle, 2 for anvil block, 3 for the anvil pad, 4 for support down iron, 5 for last support iron, 6 for pull bar, 7 be that first rotary air valve, 8 is that first rotary air valve, 9 is connecting rod for linkage, 14 for motor, 13 for reductor, 12 for compression cylinder, 11 for working cylinder, 10.
The specific embodiment
See figures.1.and.2, pneumatic hammer of the present invention comprises motor 12, reductor 11, linkage 13, compression cylinder 10, working cylinder 9 and anvil block 2.The output of motor 12 is connected with reductor; Reductor 11 is connected with an end of linkage, and the other end of linkage 13 is connected with the piston rod of compression cylinder 10, and compression cylinder 10 is connected with second appendix through first appendix with working cylinder 9; The piston rod of working cylinder is provided with to iron 5; Anvil block 2 is positioned under iron, and anvil block is provided with down and supports iron 4, is provided with anvil pad 3 at anvil block and following supporting between the iron 4.The switching device shifter that also comprises a switching pressurized air between compression cylinder and working cylinder, switching device shifter are separately positioned on first appendix and second appendix.Said switching device shifter comprises first rotary air valve 7, second rotary air valve 8 and connecting rod 14; First rotary air valve 7 is installed on first appendix; Second rotary air valve 8 is installed on second appendix, and the two ends of connecting rod 14 are connected with second rotary air valve with first rotary air valve respectively.Said switching device shifter also comprises treadle 1 and/or pull bar 6, and treadle and/or pull bar are connected with connecting rod 14.Hammer the position of last two rotary air valves into shape through treadle 1 or pull bar 6 control airs, tup is accomplished go up outstanding, hit continuously, action such as single hits and press down.For the work of motor 12, also to control through a controller (not shown), this controller is made up of single-chip microcomputer and frequency converter; Frequency converter is connected in the output of single-chip microcomputer; Frequency converter is connected with motor 12, pre-sets the program of machine operation in the single-chip microcomputer, under the operation of this program; Single-chip microcomputer output signal carries out specifically the controlling of work by frequency converter to motor to frequency converter.
The course of work of the present invention is: motor 12 comes the piston in the drive compression cylinder through decelerator 11 and linkage 13, and piston up-down is with the air in the compression cylinder.During piston up-down, compressed air alternately gets into the top or the bottom of working cylinder 9 through rotary air valve, and the piston in the working cylinder is moved up and down together with the last iron 5 that supports, and realizes the continuous strike to metal stock.
