Puncher for steel plate

Abstract

The invention relates to a puncher for a steel plate. The puncher comprises cylinders, locating plates, a workbench, a cam, a connecting ball, a connecting rod, a telescopic pipe, a drill, a driving motor, an oil tank, an oil pump, an oil supply pipe, an oil return pipe, an oil collecting tank, a filter screen and an oil nozzle, wherein output shafts of the cylinders are fixedly connected with thelocating plates; the workbench is arranged in the middle position of the upper end face of a base; the cam is fixedly connected with the output end of the driving motor; the connecting ball is fixedly arranged on the upper end face of the connecting rod; and the lower end of the connecting rod is connected with the drill through the telescopic pipe. According to the puncher, the steel plate is punched through electric energy, the position of the drill does not need to adjusted, errors are decreased, cost is reduced, efficiency is improved, the oil nozzle is connected with the oil tank throughthe oil supply pipe, the filter screen is arranged on the upper side in the oil collecting tank, the oil pump is connected with the bottom end in the oil collecting tank through the oil return pipe,lubricating oil can be automatically sprayed onto the drill, labor force is reduced, redundant lubricating oil can be recycled, and waste of lubricating oil is reduced.

Description

technical field [0001] The invention relates to the field of mechanical equipment, in particular to a steel plate puncher. Background technique [0002] The steel plate is a flat steel material that is poured with molten steel and pressed after cooling. Steel plates are flat, rectangular and can be rolled directly or cut from wide strips. Steel plates are classified according to thickness, thin steel plates < 4 mm (thinnest 0.2 mm), medium-thick steel plates 4-60 mm, and extra-thick steel plates 60-115 mm. Steel plates are divided into hot rolling and cold rolling according to rolling. The width of the thin plate is 500~1500 mm; the width of the thick plate is 600~3000 mm. Sheets are classified by steel type, including ordinary steel, high-quality steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, silicon steel, and industrial pure iron sheets, etc.; by professional use, there are plates for oil drums, Enamel plates, bu...

Problems solved by technology

[0003] During the production process of the steel plate, drilling operations are often required, but the existing steel plate is drilled through a drilling machine or a drilling rig, and the position of the drilling machine or drilling machine needs to be adjusted, and the position of the steel plate cannot be fixed, resulting in large errors and high costs. The efficiency is low. At the same time, in
