What Is a Shear Plane?

Shearing machine is a kind of machine tool, it uses hydraulic drive, reliable safety performance and easy operation. Shear working blade length: 400mm, 600mm, 700mm, 800mm, 1000mm, 1200mm; eight levels of shearing force from 63 to 400 tons, suitable for users of different scales and requirements. No foot screws are required for installation. Diesel engines can be used for power without a power source. Shears are suitable for metal recycling processing plants, scrap car dismantling sites, smelting and foundry industries, cold cutting, pressing and flanging of various shapes of steel and various metal materials, as well as powder products, plastics, fiberglass, and insulation Material and rubber press molding. Shears are divided into different types: metal shears, combined punching shears, hydraulic shears and bar shears. The most commonly used metal shears are crocodile shears and gantry shears.

Shear is a kind of mechanical equipment for cutting metal materials. In the rolling production process, after the ingots and billets with large cross-sections are rolled, their cross-sections become smaller and their lengths increase. In order to meet the requirements of subsequent processes and product size specifications, all steel production processes must have a shearing process.

The purpose of the shearing machine is to cut the fixed length, the head, the tail, the edge, the specimen, and the local defects of the rolled product. Shearing machine is one of the important auxiliary equipment in rolling machinery, because the capacity of the shearing machine directly affects whether the production capacity of the rolling mill can be fully utilized and the balance of the metal process of the rolling production line.

Shears are also widely used in machinery manufacturing and repair departments. ^[1]

Parallel blade shears

The two cutting edges of a parallel-edged shearing machine are parallel to each other. It is usually used to transversely cut square and rectangular steel billets in the hot state. It can also be used for cold-shearing profiles, and the blade is made into a shaped cutting edge to cut non-rectangular cross-sections.

According to the movement characteristics of the cutting mechanism, the parallel blade shearing machine is divided into two types: upper cutting type and lower cutting type.

The lower cutting edge of the upper cutting machine is fixed; the upper cutting edge is used for cutting. Its shearing mechanism usually adopts: crank link mechanism.

Both cutting edges of the down-cutting shear are moved, and the cutting process is achieved by the lower cutting edge rising. Its shearing mechanism usually has eccentric shaft type and floating type.

The maximum shearing force that a parallel-edged shearing machine can withstand at work is its main parameter, so people are used to naming it with the maximum shearing force. ^[1]

(1) The motor adopts a programmable controller as required;

(2) The hydraulic system is controlled by an advanced cartridge valve or slide valve system, and a hydraulic press with centralized button operation;

(3) Its pressure, speed and stroke can be adjusted according to the needs of the process, and it can complete two processes: pressing and forming.

Hydraulic shearing machine, this series of models is suitable for metal recycling processing plants, scrap car dismantling yards, smelting and casting industries, cold cutting of various shapes of steel shears and various metal structures, and processing into qualified charge Product features of this series:

(1) Hydraulic drive, easy operation and simple maintenance.

(2) Working knife edge length: 400mm, 600mm, 700mm, 800mm, 1000mm, 1200mm, and 8 levels of shear force from 63 to 400 tons. Shears with a cutting edge of more than 700mm are particularly suitable for cutting scrapped cars.

(3) No foot screws are required for installation. Diesel engines can be used for power without a power source. ^[2]

(1) Without learning, people who do not understand the structure, performance and operating procedures of the machine shall not start the machine without authorization.

(2) The lubrication points of the machine should be filled with lubricating oil at least once per shift.

(3) The hydraulic oil added to the fuel tank should be strictly used with high-quality anti-wear hydraulic oil, which must be strictly filtered, and sufficient oil quantity should always be maintained, and when it is insufficient, it should be filled immediately.

(4) The fuel tank should be cleaned and replaced with new oil every six months, but the first time the filter oil is not cleaned for more than one month, and the new oil used once is strictly filtered and allowed to be used again.

(5) When there is a serious oil leak or an abnormal phenomenon occurs during work, the vehicle shall be stopped immediately, the cause shall be analyzed, and the fault shall be eliminated.

(6) During the operation or packing of the machine, it is not allowed to repair or touch the moving parts with hands, and it is strictly forbidden to press materials in the bin with hands or feet.

(7) When adjusting pumps, valves, and pressure gauges, it must be performed by experienced technical workers. If the pressure gauge is found to be faulty, it should be checked or updated immediately. ^[2]
