Description

Working mechanism of the Press-scissorsCombined sectional shears with a force of 40-150 tons, models SMZh652, NV5221, NV5222, NV5223, NV5224, have a fully electromechanical drive without the use of hydraulic systems.

The clamping of blanks on the strip and sectional sections is carried out automatically to any thickness due to the movement of the sliders of the automatic clamping devices without the operator's participation. The clamps, which the press shears are equipped with, automatically adjust the stops for each number of rolled products, made of high-quality structural steel that has undergone heat treatment. Automatic clamps reliably protect the operator from the impact of the recoil when cutting blanks. The press shears can be additionally equipped with specialized knife plates for cutting various steel sections, strips and non-ferrous rolled products 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 30 made of tool alloy steel that has undergone heat treatment. The design of the knife plates makes it possible to cut round rolled products less than 2 mm smaller than the nominal diameter of the hole in the knife plate.

Working table of the press shearsThus, it makes it possible to cut all round rolled products with a diameter from 8 mm to 70 mm with specialized knife plates. The press shears can be equipped with a centralized dual-line lubrication system. The press shears can be equipped with a stop for cutting off measured blanks. The stop is equipped with a tool ruler with which, without marking, it is possible to cut blanks of the required length. The press shears can be equipped with a specialized table that allows cutting the strip at an angle. The angle value is set using a sliding stop. A set of drawings of quickly wearing parts is supplied with the press shears. The accuracy of the equipment complies with TU 3828-001-23881227-2014. The electrical circuit of the machine includes:

  • an interlock that allows the section electromagnets to be turned on only in the upper position of the balancer and slider, which is carried out by limit switches.
  • an interlock that prohibits operation with the guards removed, which is carried out by limit switches. When the flywheel guard curtain is removed, the limit switch prohibits the electric motor from turning on and switches the circuit to the setup mode.

We are ready and have sufficient experience in implementing both standard and unique projects for the manufacture of combined press shears for processing section and sheet metal.
