Claims

[Scope of utility model registration request]

A frame with an internally hollow structure made entirely of thin plates and a mouth-shaped front face, and a support fixed to a table at the bottom of the space so as to fit within the window-shaped space surrounded by the frame. a ram that is fitted into the support from above and guided vertically by ram guides on both sides of the support without contacting the frame; and a ram with a mouth-shaped front face and a window at the top of the frame. A hydraulic cylinder unit as a ram drive mechanism is connected to the top surface of the ram at the tip of a plunger disposed above the space and protrudes downward; a movable shearing blade and a fixed blade, a pair of upper and lower clamp pieces that are located in a path through which the plurality of bars reach the fixed blade from the rear of the support base and grip each bar from above and below, and the clamps. It consists of a bar material clamping mechanism equipped with a single pressure cam, and the movable blade and the fixed blade are provided with a plurality of pairs of cutting blades facing each other, and the position of each cutting blade on the movable blade side is is shifted vertically little by little, and hydraulic equipment such as a hydraulic pump and an accumulator connected to the ram drive hydraulic cylinder unit are accommodated in the internal space of the frame, and the entire lower part of the frame is covered with the hydraulic pressure. A bar cutting device characterized in that it is used for a hydraulic oil reservoir in a system.
