Method and device for press-forming of artificial quartz slab

Abstract

The invention relates to a method and a device for the press-forming of an artificial quartz slab. The method comprises the following steps: according to the device for the press-forming of the artificial quartz slab, a plurality of air springs are adopted as a pressure system which to press a vibration platform; firstly, the air springs are uniformly distributed around the vibration platform, the upper part of each air spring is connected with a stander through a connecting mechanism, and the lower part of each air spring is connected onto the vibration platform through a connecting mechanism; then, an eccentric wheel on the vibration platform is started to vibrate; and during the process of press-forming, the air pressures of the air springs are regulated, and then, the pressure on materials on a material bed applied by the vibration platform is regulated. Compared with the prior art, according to the technical scheme of the invention, an oil cylinder or a steam cylinder in the prior art is replaced through using the air springs as the pressure system; and due to the characteristics of the air springs, the damage to equipment caused by the vibration of the eccentric wheel is alleviated, and the stress unevenness of the vibration platform is reduced.

Description

technical field [0001] The invention belongs to the technical field of quartz stone pressing, in particular to an artificial quartz stone plate pressing method and device. Background technique [0002] The artificial quartz stone industry has developed rapidly this year, and the rapid development of both the number of enterprises and the scale of the market is staggering. However, the price and profit of sheet metal have declined particularly rapidly. The reason is that the rapid expansion of market demand and immature equipment and technology have led to a high defective rate of many manufacturers.

Problems solved by technology

However, the price and profit of sheet metal have declined particularly rapidly. The reason is that the rapid expansion of market demand and the immature equipment and technology have led to a high defective rate of many manufacturers.

[0003] The suppression scheme in the existing technology is that the pressure system withstands the vibration platform, and the vibration platform vibrates. At present, the vibration technology mostly uses eccentric wheel vibration, so the vibration force not only acts up and down, but also produces strong jitter in the left and right directions

The pressure system exerts force vertically downwards. When there is left and right shaking force, it will cause great damage to the pressure system.

[0004] Such a large vibration platform is only pressed by a few oil cylinders or cylinders, it is difficult to ensure the uniformity of force on the vibration platform, and it vibrates under the premise of uneven pressure. The method to ensure the flatness of the artificial quartz stone plate is generally to thicken the vibration The platform, or the vibrating platform pulls the ribs, which presents another big problem. The thicker the vibrating platform, the lower the conductivity of the shock force, so it is necessary to increase the shock force

In this way, the equipment is more likely to be damaged, and after the flatness is reduced, a bigger problem arises
