Embodiment 1

[0036] In Embodiment 1, a method for hot stamping of galvanized steel sheet is provided. Galvanized steel sheet 1 includes a steel sheet body 10 and a galvanized layer 11. Before hot stamping of galvanized steel sheet 1, the surface of galvanized steel sheet 1 is sprayed The heat layer 12, the heat absorbing layer 12 evenly covers the galvanized layer 11.

[0037] Wherein, the specific steps of the galvanized steel sheet hot stamping forming method are as follows:

[0038] (1) Steel coil uncoiling: place the steel coil with galvanized layer on the uncoiler, uncoil the steel coil, and the steel strip after the uncoiled steel coil enters the cleaning station and straightening station, and then enters the plate through the pinch roller Blank blanking area;

[0039] (2) Punching the slab: The uncoiled, cleaned and straightened steel strip is sent to the blanking station through the pinch roller, first enters the metering section, and the metering roller sends the steel strip inte...

Embodiment 2

[0047] In the second embodiment, a hot stamping forming method of galvanized steel sheet is provided. The galvanized steel sheet 1 includes the steel sheet body 10 and the galvanized layer 11. Before the hot stamping of the galvanized steel sheet 1, the heat-absorbing Layer 12, the heat absorbing layer 12 is evenly covered on the galvanized layer 11.

[0048] Wherein, the specific steps of the galvanized steel sheet hot stamping forming method are as follows:

[0049] (1) Steel coil uncoiling: place the steel coil with galvanized layer on the uncoiler, uncoil the steel coil, and the steel strip after the uncoiled steel coil enters the cleaning station and straightening station, and then enters the plate through the pinch roller Blank blanking area;

[0050] (2) Punching the slab: The uncoiled, cleaned and straightened steel strip is sent to the blanking station through the pinch roller, first enters the metering section, and the metering roller sends the steel strip intermitt...

Embodiment 3

[0058] In the third embodiment, a hot stamping forming method of galvanized steel sheet is provided. The galvanized steel sheet 1 includes a steel sheet body 10 and a galvanized layer 11. Before the hot stamping of the galvanized steel sheet 1, heat-absorbing Layer 12, the heat absorbing layer 12 is evenly covered on the galvanized layer 11.

[0059] Wherein, the specific steps of the galvanized steel sheet hot stamping forming method are as follows:

[0060] (1) Steel coil uncoiling: place the steel coil with galvanized layer on the uncoiler, uncoil the steel coil, and the steel strip after the uncoiled steel coil enters the cleaning station and straightening station, and then enters the plate through the pinch roller Blank blanking area;

[0061] (2) Punching the slab: The uncoiled, cleaned and straightened steel strip is sent to the blanking station through the pinch roller, first enters the metering section, and the metering roller sends the steel strip intermittently acc...

Description

technical field [0001] The invention relates to the technical field of hot stamping devices, in particular to hot stamping forming equipment for galvanized steel sheets. Background technique [0002] The hot stamping process (hot stamping) was first developed by a Swedish company and applied for a patent (GB1490535, 19771102), which is used to manufacture saw blades and lawn mower blades. However, in view of the lightweight, safety and impact resistance of automobiles, the demand for high-strength automobile structural steel plates has become increasingly apparent. In 1984, SAAB Automobile Company introduced hardened boron steel parts into automobile manufacturing for the first time (Saab9000), becoming the first The company introduced the hot stamping technology into the automotive field, which has sparked another research upsurge in hot stamping technology. [0003] The hot stamping forming process refers to: first heating the material (ultra-high strength / high strength s...
