Description

Technical Field

[0001] The utility model belongs to the technical field of hinge beam press assembly, and particularly relates to an auxiliary mechanism for piston assembly of a hinge beam press. Background Technique

[0002] A six-sided top press is composed of six hinge beams connected through pin shafts with hinge beam lugs from six directions to form a hexahedron rigid frame, and the lower hinge beam is installed on the machine base. Among them, each hinge beam includes a hinge beam cylinder body, and a large-diameter oil cylinder is arranged inside the hinge beam cylinder body. The work of the large-diameter oil cylinder is controlled by a hydraulic system to drive the cemented carbide top hammer to displace. Among them, the piston rod is a part of the piston, and assembly needs to be carried out between the top hammer and the piston rod before the hinge beam combination.

[0003] The assembly between the top hammer and the piston is first carried out by assembling the top hammer, steel ring, small cushion block, and large cushion block and then installing them on the piston rod; as Figure 6 shown, the top hammers are all installed in the steel ring by interference fit, the cooling circulating water is sealed in the steel ring water tank by welding and sealing, then the small cushion block is installed in the steel ring, the steel ring is buckled on the large cushion block and then fixed and adjusted by four high-strength bolts, and the lower end of the large cushion block is connected to the piston rod through several bolts.

[0004] In addition, the outer diameter of the cemented carbide top hammer can be 80-200mm. For small-diameter top hammers, manual handling can be used for assembly with steel rings and cushion blocks, and manual handling can be used to achieve the assembly between the cushion block and the piston rod. However, for larger-diameter top hammers, their weight is relatively large. At this time, a lifting tool needs to be used to carry the assembled top hammer. However, it is found in practice that it is very difficult to align the bolt holes of the cushion block with the bolt holes on the piston rod by means of a lifting tool, and the angle of the cushion block needs to be frequently adjusted, and mostly manual support of the cushion block is required to adjust the angle of the cushion block, and the operation is relatively troublesome and has a certain degree of danger.

[0032] The assembly between the anvil 16 and the piston is first assembled by the anvil 16, the steel ring 17, the small cushion block, and the large cushion block 18 and then installed on the piston rod 15; as Figure 6 shown, the anvil 16 is installed in the steel ring 17 by interference fit, the cooling circulating water is sealed in the steel ring water tank by welding and sealing, then the small cushion block is installed in the steel ring, the steel ring is buckled on the large cushion block and fixed and adjusted by four high-strength bolts, and the lower end of the large cushion block 18 is connected to the piston rod 15 through a plurality of bolts.

After that, through the extension of the first oil cylinder and the second oil cylinder, the first arc-shaped clamping plate and the second arc-shaped clamping plate can clamp the side surface of the cylindrical part of the anvil steel ring. Then, through the contraction of the oil cylinder 5, the anvil is driven to rise. Through the operation of the second motor, the anvil can be driven to move leftward. When the anvil is coaxial with the hinge beam 14, the second motor stops moving. Through the extension of the oil cylinder 5, the anvil moves downward. Then, through the operation of the first motor, the anvil can rotate circumferentially, and thus the anvil spacer block 18 rotates. When the bolt holes of the anvil spacer block are aligned with the bolt holes on the piston rod, the first motor stops working. Through the contraction of the first oil cylinder and the second oil cylinder, the clamping of the anvil steel ring is released. Through the contraction of the third oil cylinder and the fourth oil cylinder, the clamping of the anvil spacer block is released. At this time, the lower end surface of the anvil spacer block contacts the upper end part of the piston rod 15 and the bolt holes are aligned, which is convenient for assembly.
