Automatic water jet cutting machine for automobile sheet metal

Abstract

The invention discloses an automatic automobile metal plate water jet cutting machine which comprises a collecting bin, U-shaped frames are symmetrically mounted at the two ends of the top of the collecting bin, a mounting base is arranged on the inner sides of the two U-shaped frames jointly, cutting equipment is mounted in the mounting base, a nozzle is arranged at the bottom end of the cutting equipment, and a water inlet is formed in the bottom end of the nozzle. And electric telescopic rods are symmetrically mounted in the middle positions of the two sides of the top of the mounting seat. An electric telescopic rod is controlled to be shortened, a U-shaped plate is driven to descend, a funnel bin completely covers a nozzle, when an automobile metal plate is cut, a servo motor is controlled to rotate, the funnel bin is forced to rotate slowly, when a water column sprayed out of the nozzle cuts the metal plate, part of splashed water can be completely blocked by the rotating funnel bin, and therefore the cutting efficiency of the automobile metal plate is improved. And centrifugal force generated by rotation enables cutting water gathered on the inner side of the annular groove to be automatically and rapidly discharged into the external environment from the drainage hole, and the situation that water splashes all around in the metal plate cutting process of the water jet cutting machine is completely avoided.

Description

technical field [0001] The invention relates to the technical field of water jet cutting machines, in particular to an automatic water jet cutting machine for automobile sheet metal. Background technique [0002] The jet cutting machine is to pass ordinary water through an ultra-high pressure pressurizer, pressurize the water to 3000bar, and then generate a water jet of about 3 times the speed of sound through a water nozzle with a channel diameter of 0.3mm, which can be easily controlled by a computer. It can cut soft materials of any shape, such as paper, sponge, fiber, etc. If sand is added to increase its cutting force, it can cut almost any material. It is an important equipment in automobile sheet metal. [0003] The patent of publication number CN108161766A discloses a water jet cutting machine for automobile sheet metal. The pressure plate set on the water jet cutting machine for automobile sheet metal can be pressed down under the force of the air pump, so that the ...

Problems solved by technology

[0004] 1. The existing water jet cutting machine prevents the sprayed water column from splashing on the staff by setting a protective cover, but the protective effect can be limited only by setting the protective cover that can block the two sides of the nozzle, and it is impossible to While all around the nozzle is covered, it will not affect the normal cutting operation of the water jet cutting machine;

[0005] 2. Moreover, when the plate-type protective cover provided by the existing water jet cutting machine is splashing water from the waterproof column, the water droplets blocked by it will all flow to the automobile sheet metal after gathering, and the sand particles in the cutting wa
