Nowadays, there are many equipment manufacturers, and standard and non-standard products are constantly emerging. In addition to the quality and service of the scrap metal shearing machine, how to choose the suitable shearing equipment according to your own situation with the minimum investment for the maximum efficiency is always confuse our customers. Today TEYUN will compare the gantry shears and alligator shears to help our customers to choose the suitable machines. Scrap metal shearing machine In the scrap steel processing industry, the scrap metal shearing machine is mainly used to cut the raw scrap steel into qualified materials that meet the purchase requirements of the steel mill. There are roughly two common types: alligator shears and gantry shears (hereinafter referred to as alliagtpor/crocodile shears and gantry shears). Alligator shears and gantry shears are composed of shearing mechanism, pressing mechanism and transmission device. It can also be divided into two parts: mechanical part and hydraulic part. So alligator shears or gantry shears, how to choose? Working principle: The hydraulic transmission device is driven by the electric motor (the diesel engine can be used as power in the place without power supply), and the hydraulic transmission device drives the pressing mechanism and the shearing mechanism to achieve the purpose of cutting the steel plate. Generally, the scrap metal shearing port of the steel plate shearing machine is composed of two upper and lower blades, the lower blade is mostly a fixed blade, and the upper blade is a movable blade. When the scrap enters the knife edge, the pressing device presses down to fix the scrap, and then the upper blade moves downward to cut the scrap. After cutting, the upper blade and the pressing mechanism return to the original position and wait for the next shearing process, and so on. The main parameters: Common data of steel plate shears are: shear force, blade size, shear frequency, and total mechanical power. 1. Shearing force: that is, the shearing pressure, generally marked with the maximum shearing force, and the units are slightly different from different manufacturers. For example, kn and t, kn is the international system unit of force, and it is also the legal unit of force in our country. 1t force=9.8kn≈10kn, that is to say, the shear force of 2000kn marked with kn is about 200t shear force. The greater the shear force, the greater the thickness of the metal that the device can cut. 2. The length of the blade: that is, the size of the blade, expressed in mm (mm), which is proportional to the maximum opening, that is, the longer the blade, the larger the blade, and the larger the metal size it can cut. 3. Cutting frequency: that is, the number of cuts per minute. The movement method of the alligator scissors is similar to a lever. The longer the blade, the larger the opening, and the longer the cutting process will take. Therefore, the machine with the higher shear forc...
