Large energy-saving water cooling air hammer

Abstract

The invention relates to a large energy-saving water cooling air hammer, which comprises a power transmission mechanism (1), a crank link mechanism (2), a front cylinder (3) and a rear cylinder (4). The front cylinder (3) comprises a front cylinder sleeve (3.1), a guide sleeve I (3.2) is arranged in the front cylinder sleeve (3.1), a front lead (3.4) is arranged in the guide sleeve I (3.2), a guide sleeve II (4.2) is arranged in a rear cylinder sleeve (4.1), a rear lead (4.4) is arranged in the guide sleeve II (4.2), a water pore I (3.3) is arranged on the inner wall of the front cylinder sleeve (3.1), a water pore II (3.5) is arranged on the outer wall of the front lead (3.4), a water pore III (4.3) is arranged on the inner wall of the rear cylinder sleeve (4.1), and a water pore IV (4.5) is arranged on the outer wall of the rear lead (4.4). The large energy-saving water cooling air hammer has the advantages that the two cylinders can be sufficiently cooled, the heating value of the air hammer in operation is reduced, the service life of the air hammer is prolonged, and energy consumption and current fluctuation of the air hammer in operation are low.

Description

technical field [0001] The invention relates to a large energy-saving water-cooled air hammer, which belongs to the field of forging machinery and equipment. Background technique [0002] The air hammer is a kind of free forging machine, it has two cylinders, the compressed air cylinder compresses the air, sends it into the working cylinder through the distribution valve, and pushes the piston and the hammer head to move up and down to play a hammering role. It is flexible in operation and is widely used in middle The working principle of the production of small forgings is: the motor drives the compression cylinder and the compression piston to move up and down through the reduction mechanism, crank and connecting rod to generate compressed air. When the upper and lower air passages of the compression cylinder communicate with the atmosphere, the compressed air does not enter the working cylinder. , the motor is idling, the hammer head does not work, the up and down rotary ...

AI Technical Summary

Problems solved by technology

[0003] At present, the specifications of air hammers on the market are all below 2T, which are only suitable for small and medium-sized forgings, because large air hammers generate a lot of heat during operation, and the fuselage and hammer shaft are prone to seizure due to thermal expansion and contraction, making it unusable. The large heat is easy to evaporate the lubricating oil, so that the lubricating effect cannot be achieved, and the service life of the air hammer is short

In addition, the existing air hammer still has problems such as high energy consumption and large current fluctuations.
