Large Sheet Metal Shears Iron Cutting Machine
Box type Scrap Metal Shear is often seen as the "all-purpose mobile factory" in the field of scrap handling. It integrates the three functions of extrusion, forming and shearing, and is especially suitable for processing large-sized and disordered scrap steel.
Process logic: two-dimensional pre-extrusion and continuous shearing
The core advantage of box shears lies in their huge bin design, which can directly handle the super-long and super-wide waste that ordinary crocodile shears can not handle.
1. Box-type pre-compression:
After the material enters the bin, the side gland is closed first. -Physical process: The side gland horizontally squeezes the fluffy scrap steel (such as scaffolding and scrapped frame) through strong hydraulic thrust.
-Forming significance: This is not only to reduce the volume, but more importantly, to force the scrap steel into a "cuboid column" with a regular section to provide stable physical support for subsequent shearing.
2. Stepping continuous cutting:
The pushing cylinder is pushed in the rear step by step according to the set length (fixed length), and the heavy pressure knife in the front falls vertically.
-Production rhythm: Compared with gantry shears, box shears usually have a faster opening and closing frequency, which realizes the efficient flow operation of "squeezing, moving and shearing at the same time".
System benefits: High integration and low base cost
The design of this Metal Shear solves the pain point of heavy machinery's high dependence on the site.
1.Integral base:
The equipment is usually of integral frame construction, eliminating the need to excavate extremely deep reinforced concrete foundations like large gantry shears.
-Industrial value: This greatly shortens the installation cycle and provides a certain degree of mobility (some models with support legs), which is suitable for recycling enterprises that need to adjust the site frequently.
2. High rate energy consumption ratio:
Double-pump confluence technology is widely used in modern box shears. In the no-load closing stage, the large-flow pump is used to increase the speed, and the high-pressure pump is automatically switched at the moment of shearing the high-hardness material.
-Energy efficiency performance: This dynamic power allocation has reduced the unit energy consumption of 330,000 projects by about 12% -15%.
