Abstract
The utility model relates to the technical field of a punch, in particular to an excessive cutting protection device of a punch, which comprises a saw tooth, a fixing plate of the saw tooth, an oil cylinder, a piston and a slide block, wherein the saw tooth is installed at the fixing plate of the saw tooth, the piston is positioned at a position below the saw tooth and is installed in the oil cylinder, the slide block is installed at the saw tooth and is installed at the saw tooth by a fixing pin of the saw tooth and a worm gear, and a sealing component is arranged between the piston and the oil cylinder in an encircling way. A nut of the oil cylinder is arranged between the piston and the oil cylinder. The bottom of the side wall of the oil cylinder is provided with an oil inlet joint. The excessive cutting protection device of the punch, which is disclosed by the utility model, can play a role in excessive cutting protection under the functions of the piston and the oil cylinder when the slide block is possible to cause excessive cutting, and avoids damaging the slide block or a workpiece; and moreover, the position of the slide block can be regulated by the fixing pin of the saw tooth and the worm gear, thereby the stroke of the slide block is regulated and the working accuracy of the slide block is enhanced.
Description
Technical field
The utility model relates to the punch press technical field, particularly relates to a kind of punch press and crosses the sanction protective device.
Background technology
Punch press is the common equipment of machining, and its working dynamics is very big, workpiece is stamped into the shape of appointment under up to a hundred tons strength.Because the operating rate of slide block is fast, quality is big, careless slightlyly just may cause sanction, both caused finishing processing purpose, also may cause the damage of slide block or punch press.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of punch press to cross the sanction protective device.
The purpose of this utility model realizes by following technical measures.
A kind of punch press is crossed the sanction protective device; comprise saw tooth, saw tooth fixed head, oil cylinder, piston and slide block, described saw tooth is installed on saw tooth fixed head, and described piston is positioned at the position under the described saw tooth; described piston is installed in the described oil cylinder, and described slide block is installed on described saw tooth.
Described slide block is installed on described saw tooth by saw tooth steady pin and worm gear.
Between described piston and the oil cylinder around seal is set.
The oil cylinder nut is set between described piston and the oil cylinder.
Described oil cylinder sidewall bottom is provided with fuel inlet fitting.
Punch press of the present utility model is crossed and is cut out protective device under the effect of piston and oil cylinder, can play a part to be when slide block may cause cutting out and cut out protection, avoids damaging slide block or workpiece; And by saw tooth steady pin and worm gear can adjusting slider the position, thereby adjust the stroke of slide block, improve the operating accuracy of slide block.
Description of drawings
