Description
Technical Field
The utility model relates to a boats and ships forging is with two arm-type free forging electro-hydraulic hammer unloading device.
Background
The electro-hydraulic hammer is energy-saving and environment-friendly novel forging equipment and is divided into a single-arm electro-hydraulic hammer and a double-arm electro-hydraulic hammer, after the existing electro-hydraulic hammer works for a long time, an oil supply cavity can generate large pressure, if the electro-hydraulic hammer is not timely unloaded, the electro-hydraulic hammer is easy to impact the top, oil is seriously heated, and other safety accidents are easily caused.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a two-arm free forging electro-hydraulic hammer unloading device for ship forgings, which comprises a base, wherein an anvil block is arranged on the base, an upper anvil hammer is arranged above the anvil block, the upper anvil hammer is connected with a piston head through a hammer rod, the piston head is arranged in an electro-hydraulic hammer working cylinder, and the inner wall of the electro-hydraulic hammer working cylinder is provided with a graphite layer; the electro-hydraulic hammer working cylinder is fixedly arranged on the frame, the electro-hydraulic hammer working cylinder is connected with the energy accumulator through an oil pipe, and the oil pipe is provided with a magnetic control Hall switch; baffles are arranged around the frame.
Further, a circular window for operation is arranged on one of the baffles.
The utility model discloses a magnetic control hall switch is connected with the energy storage ware, improves off-load efficiency, reduces the friction of piston head and electrohydraulic hammer working cylinder inner wall through the graphite layer, improves forging efficiency, avoids forging the spark to spatter all around through the baffle, improves the production security.

In the figure, 1 is an electro-hydraulic hammer working cylinder, 2 is a graphite layer, 3 is a magnetic control Hall switch, 4 is an oil pipe, 5 is an energy accumulator, 6 is an upper anvil hammer, 7 is an anvil block, 8 is a frame, 9 is a base, 10 is a hammer rod, 12 is a window, and 13 is a piston head.
Detailed Description
As shown in fig. 1, the double-arm free forging electro-hydraulic hammer unloading device for the ship forge piece comprises a base 9, wherein an anvil block 7 is arranged on the base 9, an upper anvil hammer 6 is arranged above the anvil block 7, the upper anvil hammer 6 is connected with a piston head 13 through a hammer rod 10, the piston head 13 is arranged in an electro-hydraulic hammer working cylinder 1, and a graphite layer 2 is arranged on the inner wall of the electro-hydraulic hammer working cylinder 1; the electro-hydraulic hammer working cylinder 1 is fixedly arranged on the frame 8, the electro-hydraulic hammer working cylinder 1 is connected with the energy accumulator 5 through an oil pipe 4, and the oil pipe 4 is provided with a magnetic control Hall switch 3; baffle plates 11 are arranged around the frame 8. The electro-hydraulic hammer working cylinder 1 and the magnetic control Hall switch 3 are connected with an external PLC controller. When the upper anvil hammer 6 rises, the magnetic control Hall switch 3 is opened, the oil pump and the energy accumulator 5 simultaneously supply oil to the oil supply cavity of the electro-hydraulic hammer working cylinder 1, when the upper anvil hammer 6 falls, the magnetic control Hall switch 3 is closed, oil output by the oil pump enters the cavity of the energy accumulator 5, and when the upper anvil hammer 6 stops working, the magnetic control Hall switch 3 controls the oil pump to unload.
As shown in fig. 2, a circular window 12 is provided for operation on the front panel 11.
