Description

Technical Field

[0001] The utility model relates to the technical field of electro-hydraulic hammer accessories, in particular to a protective device for an electro-hydraulic hammer. Background Art

[0002] The electro-hydraulic hammer is a new type of forging equipment that is energy-saving and environmentally friendly. It is divided into single-arm electro-hydraulic hammer and double-arm electro-hydraulic hammer. The electro-hydraulic hammer adopts the principle of hydraulic and pneumatic technology, specifically a pump accumulator drive device, and uses the action principle of air pressure drive and hydraulic energy storage. Under the action of the operating valve, it realizes the rapid lifting and striking of the forging hammer. The working principle of the double-arm electro-hydraulic hammer is to use electricity as energy, lift the hammer head through hydraulic pressure to establish gravitational potential energy, and compress gas to store energy at the same time. When striking, under the action of the gravity of the hammer head and the expansion thrust of the gas, the potential energy of the hammer head is converted into the kinetic energy of the hammer head, thereby striking the high-temperature forgings and working. Because impurities will splash during forging and hammering, and the existing electro-hydraulic hammers are not well protected, the splashing impurities are easy to cause personal injury to the operators nearby.

[0003] For example, a protective device for an electro-hydraulic hammer with a publication number of CN212551542U includes a hammer frame, and also includes a first protective door and a second protective door. The hammer frame is provided with a receiving groove for the first protective door and the second protective door to pass through; the first protective door and the second protective door are slidably connected with the receiving groove along the opening direction of the receiving groove; and the first protective door is provided with a synchronization member for synchronous movement with the second protective door. By providing the first protective door, the second protective door, the receiving groove, and the synchronization member, when the electro-hydraulic hammer is used to process the workpiece, the workpiece is first placed on the workbench, and then the first protective door is pushed so that the first protective door and the receiving groove slide relative to each other. The synchronization member causes the second protective door to move synchronously with the second protective door, so that the first protective door and the second protective door surround the workbench to prevent splashing oxide scale from causing harm to the workers, thereby improving the safety of the electro-hydraulic hammer.

[0004] In practical applications of the above technical solution, the provision of the protective door affects the placement of materials and is not conducive to the processing of materials.

[0005] Therefore, it is necessary to invent a protective device for an electro-hydraulic hammer to solve the above problems. Utility Model Content
