Description

Technical Field

[0001] This invention relates to the field of elevator component processing technology, specifically to processing equipment and processing methods for producing elevator buffer plunger cylinders. Background Technology

[0002] The plunger cylinder in the elevator hydraulic buffer is the core cylinder assembly of the entire buffer. It is usually a precision pressure vessel and motion guide device. The plunger cylinder is mainly composed of cylinder body, plunger rod, end cap and other components. Among them, the cylinder body, as the core pressure vessel and motion guide foundation of the elevator hydraulic buffer plunger cylinder, has an extremely precise and strict processing procedure.

[0003] During the "temporary" period (which may range from several days to several months) before the cylinder block is machined, assembled, and lubricated, its precision-machined surfaces (especially inner holes, end faces, threaded holes, etc.) are protected from moisture, oxygen, and corrosive gases (such as SO2, H2S, Cl) in the environment. - To prevent corrosion from ions and salt spray, and to avoid the formation of "floating rust" or even pitting corrosion, temporary rust prevention is required for the finished cylinder block.

The front end of the second rotating shaft passes through the top plate and is fixedly connected to a rotating block. A rotating rod is provided through the inner cavity of the rotating block. The left end of the rotating rod is fixedly connected to an L-shaped movable plate, and a spring is sleeved on the outside of the rotating rod. The spring is located between the L-shaped movable plate and the rotating block.

[0010] Preferably, a connecting rod is fixedly connected to the front side of the reciprocating block, and a sprayer is fixedly connected to the bottom of the connecting rod. A volatile corrosion inhibitor is added inside the sprayer.

Two sleeve plates are fixedly connected to the front side of the mounting plate, and a reciprocating rod is hinged between the two sleeve plates.

A connecting rod is fixedly connected to the top of the lifting block, and a circular plate is fixedly connected to the top of the connecting rod. Several dust plugs are installed on the top of the circular plate.

[0012] Preferably, a circular opening is provided at the top of the base plate near the left side, and a rotating platform is installed at the top of the base plate near the left side. The rotating platform has a through hole in its inner cavity, and the diameter of the through hole is larger than the diameter of the circular plate.

[0013] The processing method for elevator buffer plunger cylinder manufacturing equipment includes the following steps: S1: First, the worker attaches the cylinder block to be processed onto the protrusion and starts the motor to drive the second crank to rotate. When the second crank rotates, it can drive the first crank to swing back and forth. When the first crank swings back and forth, it can drive the V-shaped movable plate to swing synchronously. When the V-shaped movable plate swings, it can drive the rotating plate to move through the transmission groove wheel. When the rotating plate moves, it can drive the cylinder block to move synchronously through the electromagnet. S2: When the cylinder body is rotated 90 degrees, it can be moved to the top of the base plate near the left side, and the micro cylinder is activated. When the micro cylinder is activated, it can drive the toothed plate to move downward. When the toothed plate moves, it can drive the gear to rotate. When the gear rotates, it can drive the rotating block to rotate. When the rotating block rotates, it can drive the rotating rod to rotate. When the rotating rod rotates, it can drive the reciprocating block to move. When the reciprocating block moves, it can make a concave movement, thereby forming a layer of monomolecular protective film that is invisible to the naked eye on the outside of the cylinder body, effectively blocking moisture and corrosive media. S3: When the rotary table is started, it can drive the cylinder to rotate, improving processing efficiency. When the reciprocating rod rotates, it can engage with the lifting block, thereby driving the lifting block to move upward. When the lifting block moves upward, it can drive the circular plate to move through the connecting rod. When the circular plate moves, it can drive several dust plugs to move, thereby allowing the dust plugs to be inserted into the bolt holes at the bottom of the cylinder.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention involves spraying a volatile corrosion inhibitor onto the outside of the cylinder body. When VCI molecules are in a confined space or adhere to a metal surface, they slowly evaporate, forming an invisible monomolecular protective film that effectively blocks moisture and corrosive media. When the cylinder body is exposed to air before assembly, the VCI will gradually evaporate completely, ensuring thorough removal during subsequent deep cleaning processes.

[0015] 2. This invention enables the use of a special clean VCI dust plug to block the openings at both ends of the deep inner hole by inserting a dust plug into the bolt hole at the bottom of the cylinder body, thus preventing dust accumulation. Attached Figure Description
