WHAT IS AN ALLIGATOR SHEAR? An alligator shear(alligator shearing machine) is also known as the  crocodile shear. The alligator shear is a type of cutting tool whcih is widely used to cut the waste metal in metalworking.  The alligator shear is similar to a pair of scissors, but with longer, heavier blades that are designed to cut through thicker materials such as sheet metal and rebar. The blades are usually serrated, allowing them to grip the material being cut and make a clean cut. Alligator shears are commonly used in fabrication shops ,industrial applications and also in metal recycling industries.     The alligator shearing machine is a samller type of the scrap metal shearing machine compared with the heavy duty gantry shear and tiger shear(super alligator shear) The alligator shear has the advantages of the samll volum and low price but limited cutting production，so the alligator shear is normally suitable for the samll recycling recycling centre or personal using. To improve the cutting speed and reduce the labor working, the alligator shear can be equipped with the feeding box. For much more the daily production demand, the customers can consider the other scrap metal shearing machines like: super alligator shear, container shear and the gantry shear.

Introduction of Briquetting Machine The briquetting machine can bale aluminum chips, steel chips, cast iron chips, and copper chips into blocks and return them to the furnace, which can reduce burning loss, save energy, and reduce carbon. It is suitable for aluminum alloy profile factories,  steel casting factories, aluminum casting factories, copper casting factories and mechanical processing plants, etc. Working Principle The hydraulic system drives the hydraulic cylinder, and the hydraulic cylinder outputs high pressure  to cold-press metal materials such as metal shavings and powder into cylindrical cakes, which is convenient for storage, transportation, furnace production, and reduces losses during recycling and reuse. Recycling Functions 1. After being processed by the metal chip press machine, the waste metal chips can be compressed into metal chip round blocks by cold pressing and high-pressure compression. The whole process does not require heating, additives and other processes, which can prevent the remaining processes from affecting the characteristics of metal chips. These metal shavings compressed into round blocks can be directly used for incineration and remanufactured metal products. 2. The metal shavings in these metal discs will ensure the stability of the composition when they are returned to the furnace for incineration, and can also increase the density of the feed and reduce the number of feeds. The entire compression process of the briquetting machine reduces air pollution and energy consumption due to the reduction in feeding frequency, increases the furnace rate, and increases the profit margin of metal recovery and refining. 3. Compared with the block pressing machine on the market, the scrap metal briquetting machine is different in that we use a horizontal sealed design. The entire compression process is fully sealed, and there will be no waste liquid splashing around during the compression process, which ensures a clean environment and facilitates the collection of cutting fluid.

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...
