Steel plate perforating device with reset function

Abstract

The invention discloses a steel plate perforating device with a reset function. The device comprises an air cylinder, a sealing cover, a control rod, a sealing head, a piston and a compression spring, wherein a gas injection chamber I is formed in the air cylinder, a gas injection port is formed in the side wall of the air cylinder, and a gas releasing port is formed in the bottom; the sealing cover is connected to the top of the air cylinder and forms an accommodating cavity with the air cylinder, the piston is arranged in the cavity and partitions the accommodating cavity to form a ventilating chamber and a gas injection chamber II, a second gas injection port II is formed in the side wall of the sealing cover, and ventilating holes are formed in the top of the sealing cover; the sealing head is embedded into the gas releasing port and closes the gas releasing port, the lower end of the control rod is arranged in the gas injection chamber I and is connected to the top of the sealing head while the upper end of the control rod penetrates through the top of the air cylinder and is connected to the piston, and the compression spring is arranged in the ventilating chamber and the upper and lower ends of the compression spring act on the sealing cover and the control rod, respectively; an annular groove is formed in the side wall of the sealing head, and the sealing ring is embedded into the annular groove. The device disclosed by the invention is convenient to operate and time- and labor-saving if being used for perforating a thin steel plate, and potential safety hazards are avoided during perforating.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a steel plate punching device with a reset function. Background technique [0002] Thin steel plates are often used in construction projects, and according to the different needs of the specific construction site, it is often necessary to punch holes in different parts of the thin steel plates. Nowadays, when people punch thin steel plates, they usually place the steel plates on soft On the ground, the operator holds a columnar bar and presses down on the thin steel plate to punch holes in the thin steel plate. If the existing method is used to punch the steel plate, if the downward pressure on the thin steel plate is small, it can only cause partial cracking of the steel plate, and it is not easy to align during the secondary punching; if the downward pressure on the thin steel plate is large Large, the reaction force of the ground to the operator is easy to cause injury to...
