Problems solved by technology

[0002] The existing various molding machines are mainly used for the pressure requirements of carbon products and various refractory materials, building ceramics, artificial marble and other products, but for the processing of fine powder and micro powder raw materials, problems such as lamination often occur. In order to solve For this problem, the existing technology adopts the method of lake-shaped casting to make products. Due to too much water, the dried product is easy to deform, and it is also prone to problems of dryness on the outside and dampness on the inside.
This is mainly because the various existing pressure molding machines can only change the vibration amplitude, but not the vibration frequency. Due to its very complicated structure, frequency modulation is very troublesome. There is a slight error in assembly, and the operation is not stable. , the smallest needs more than 30 gears, and if two groups need more than 60 gears, there must be no error in the connection, which brings many difficulties to production and application, the cost is too high, the molding speed is too slow, and the efficiency is low
The shape is not beautiful, because the bottom corner accessories of the Heli molding machine designed in the prior art are almost all exposed outside, the operation is inconvenient, and it brings many hidden dangers to the safe production. It will soon be filled with dust, reducing the service life of the motor. Various factors determine that it is difficult to increase the density of the product with the existing technology

Abstract

The invention provides frequency modulation amplitude modulation resultant force shaping machine. It is made up of liquid hydraulic device and vibration device, the vibration device is made up of high frequency drastic vibrating device and transducer. The drastic vibrating device and transducer can be sealed and applies to the position where has too many powder, its structure is simple and beautiful, it is convenient. The vibrating range and the frequency has changed from bypast single variety to stepless frequency modulation.

Description

Technical field [0001] The invention provides a frequency and amplitude modulation combined force forming machine, which belongs to the category of pressure forming equipment, and is a technical improvement corresponding to the pressure forming equipment for powders and particles of refractory materials, architectural ceramics, artificial marble, etc. Background technique [0002] The existing various molding machines are mainly used for the pressure requirements of carbon products and various refractory materials, architectural ceramics, artificial marble and other products. However, the processing of fine powder and micropowder raw materials often has problems such as spallation. In order to solve For this problem, the prior art adopts a lake-like casting method to make products. Due to too much moisture, the dried product is prone to deformation, and it is also prone to problems of external dryness and internal wetness. This is mainly because the existing various pressure form...
