Description

Die for punching channel steel workpiece

Technical Field

The utility model belongs to the machining field, concretely relates to mould that punches a hole is carried out channel-section steel work piece.

Background

The existing channel steel workpiece needs to be provided with four oval through holes. In the prior art, when the rectangular workpiece is machined, a hole position needs to be manually marked on the channel steel, and then the machining can be completed by manually punching 4 times one hole by one hole, or 4 point position marks are marked by marking a line and positioning on the existing die and the punching is completed by 4 times. This mode has the following disadvantages: 1) in the operation process, the hands of workers frequently contact the machine tool and the die, so that potential safety hazards are high; 2) the error rate of the size and the appearance of the processed workpiece is high; 3) there is a waste of labor and resources such as equipment, molds, etc.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a mould that punches a hole to the channel-section steel work piece.

In order to solve the technical problem, the utility model discloses a following technical scheme: a die for punching a channel steel workpiece comprises an upper die assembly and a lower die assembly, wherein the upper die assembly comprises an upper die handle, an upper die plate, an upper die fixing plate, an upper die guide sleeve, buffer rubber, a punching positioning plate and four oval punching convex blades, and the buffer rubber is arranged between the punching positioning plate and the upper die fixing plate; the lower die assembly comprises a lower die base, a lower die fixing plate, a punching female die and a lower die guide upright post; the punching female die is provided with four longitudinal oval through holes, and the lower die fixing plate is provided with through holes with larger sizes corresponding to the positions of the four oval through holes.

Further, the middle of the lower die base is provided with a hollow structure.

During the use, put 10mm 800 mm's channel-section steel work piece in lower mould central point, manual operation press foot switch makes the upper die assembly punch a hole downwards, and four protruding sword that punch a hole accomplish 4 simultaneously and punch a hole, and when the upper die assembly returned to the upper level, four protruding sword that punch a hole were extracted from the channel-section steel work piece can be guaranteed to cushion rubber's elasticity. Therefore, the qualified rate of the formed part product is ensured, the production efficiency is improved, and the safety risk of staff is reduced.
