Punching and packaging process of sheet metal

Abstract

The invention provides a punching and packaging process of a sheet metal and belongs to the mechanical technical field. The process solves the problem that a positioning block on an existing metal sheet is inconvenient to arrange. The punching and packaging process of the sheet metal provided by the invention is characterized by comprising the following steps: step a, presetting a punching head position of a punching device and the position of a feeding rack; step b, placing the to-be-processed metal sheet on the feeding rack, clamping the metal sheet by a positioning structure, driving the feeding rack and the metal sheet to move to the right forward position of the punching head by a first driving structure, and then pushing the metal sheet from the feeding rack to the punching head by a second driving structure for preparation of punching; step c, punching an upward protruding positioning portion on the metal sheet which is transferred by the punching head; step d, after punching, verifying the punched metal sheet, and judging whether the punched metal sheet is a qualified product or not; and step e, taking out the punched metal sheet. According to the process provided by the invention, the protruding positioning portion can be automatically punched on the metal sheet, and the work efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a sheet metal stamping and packaging process. Background technique [0002] The Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China jointly issued the newly revised "Emission Standards of Air Pollutants for Thermal Power Plants". The new standards will be implemented on January 1, 2012, and the control and treatment of nitrogen oxide pollution is being vigorously implemented. Flue gas denitrification in coal-fired power plants is an important way to control NOx. The desulfurization and denitration catalyst is the most important part of it. During the use of the denitration catalyst, each module is made into a module called a denitration catalyst module, and then multiple denitration catalyst modules are installed. The existing denitration catalyst module is for The system of expans...

Problems solved by technology

The desulfurization and denitrification catalyst is the most important part of it. During the use of the denitrification catalyst, each module is made into a module called a denitration catalyst module, and then multiple denitration catalyst modules are installed. The existing denitration catalyst module is for The system of expansion and flue gas is a hexagonal column, which is placed in a honeycomb shape along the length of the sheet metal frame. Since the stacked denitrification catalyst modules are not directly in contact with the sheet metal frame, they are easy to loosen and slip. The positioning board is installed inside the frame, but the cost of the positioning board is relatively high, and the connection and positioning are relatively cumbersome, so how to directly integrate the positioning part on the sheet metal inner frame can reduce the production cost
