Abstract

The utility model discloses a shearing device for steel plates. The shearing device comprises a U-shaped support. Male dies are installed in the U-shaped support, female dies matched with the male dies on the lower portion are respectively installed on the two sides of the U-shaped support in a sliding mode, the male dies are provided with a plurality of trapezoidal punching blocks, the female dies are provided with cavities matched with the punching blocks, swing arms are hinged to the upper ends of the two sides of the female dies, the upper ends of the swing arms are connected with driving arms, and a synchronization rod is hinged between the two swing arms. The shearing device can shear the steel plates conveniently, the shearing efficiency is improved, the structural design is simple, and manufacturing is convenient.

Description

The shear of steel plate
Technical field
The utility model relates to the shear of steel plate.
Background technology
For producing the problem of edge crack in the original sheared edge reprocessing of steel plate process, adopt the longitudinal sample of steel plate to carry out laboratory simulation test, think, the main cause of edge crack is that the original shear surface of steel plate shears that stress that crotch, burr cause is concentrated and reprocessing technique is improper.The factors such as shear gap, lap adjustment, shear temperature, shearing force, shearing displacement all affect the shearing quality of steel plate.
Utility model content
The purpose of this utility model is to provide a kind of shear of steel plate, steel plate conveniently can be cut off, and shear efficiency has improved, and structural design is simple, easily manufactured, improves steel plate shearing precision, speed and metal recovery rate.
The technical solution of the utility model is as follows:
The shear of steel plate, include U-shaped bearing, in U-shaped bearing, punch is installed, U-shaped bearing both sides are slidably fitted with respectively the die matching with the punch of below, described punch has a plurality of trapezoidal pieces that rush, and described die has and the cavity that rushes piece and match; The upper end of described die both sides is hinged with swing arm, and swing arm upper end is connected with actuating arm, between two described swing arms, is hinged with synchronizing bar.
Described die outside is fixed with pressing plate, between pressing plate and die, has gap.
The utility model can conveniently be cut off steel plate, and shear efficiency has improved, and structural design is simple, easily manufactured, improves steel plate shearing precision, speed and metal recovery rate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the shear of steel plate, includes U-shaped bearing 1, in U-shaped bearing 1, punch 2 is installed, U-shaped bearing 1 both sides are slidably fitted with respectively the die 3 matching with the punch of below, and punch 2 has a plurality of trapezoidal pieces 4 that rush, and die 3 has and the cavity 5 that rushes piece and match; The upper end of die both sides is hinged with swing arm 6, and swing arm 6 upper ends are connected with between 7, two swing arms of actuating arm and are hinged with synchronizing bar 8, and die outside is fixed with pressing plate 9, between pressing plate 9 and die 3, has gap.
