Hydraulic high-speed water-hammering punch press

Abstract

The invention discloses a hydraulic high-speed water-hammering punch press. The hydraulic high-speed water-hammering punch press comprises a punch rack, a hydraulic water washing unit, a pore diametercontrol unit, a cooling device and a control electrical box, wherein a supporting frame and a punch table are arranged on the punch rack; the top of the supporting frame is equipped with a seat tableboard; the hydraulic water washing unit comprises a pressurizing hydraulic cylinder, a water washing pressurizing cylinder and a water supply system; a positioning sleeve is arranged on the seat table board; the pressurizing hydraulic cylinder is mounted on the seat table board through the positioning sleeve; and one side of the supporting frame is equipped with a washing fixing frame. The hydraulic high-speed water-hammering punch press adopts the pressurizing hydraulic cylinder to indirectly apply pressure to the water washing pressurizing cylinder, so that large oil cylinder pressure is converted into air pressure of the water washing pressurizing cylinder, and therefore, large air pressure instantaneously pushes water flow in the water washing pressurizing cylinder, water flow is sprayed to a to-be-processed object with high-speed impact force, water flow punching replaces conventional mould punching, and punching noises can be reduced; and meanwhile, a mould is not needed for assisting processing.

Description

technical field [0001] The invention relates to the technical field of hydraulic punching, in particular to a hydraulic high-speed water hammer punching machine. Background technique [0002] Hydraulic high-speed punching machine is a kind of punching process that can realize small-thickness metal. It has high efficiency and high processing accuracy. At present, the common hydraulic high-speed punching machine is composed of the following parts: hydraulic cylinder actuator, stamping die , hydraulic pump combination and control part, but this kind of punching machine has the following disadvantages: 1. The punching machine uses the mold to directly contact the metal to be processed, and the material removal process is realized through the assistance of the mold. Clumsy. 2. A single mold for mechanical punching can only process a single hole. If you need to process other holes, you need to replace the tool and mold. The operation is complicated. 3. The cooling method of hydrau...

[0002] Hydraulic high-speed punching machine is a kind of punching process that can realize small-thickness metal. It has high efficiency and high processing accuracy. At present, the common hydraulic high-speed punching machine is composed of the following parts: hydraulic cylinder actuator, stamping die , hydraulic pump combination and control part, but this kind of punching machine has the following disadvantages: 1. The punching machine uses the mold to directly contact the metal to be processed, and the material removal process is realized through the assistance of the mold. Clumsy. 2. A single mold for mechanical punching can only process a single hole. If you need to process other holes, you need to replace the tool and mold. The operation is complicated. 3. The cooling method of hydraulic oil is usually water cooling, but the contact between water cooling and high temperature hydraulic oil The area is small, which leads to poor cooling effect of the hydraulic oil, so the present invention provides a hydraulic high-speed water hammer punching machine
