This patent and the utility model patent applied on December 28, 2017. The existing multi station rotary dry powder automatic press used for powder briquetting of new energy vehicles, magnetic materials, electronic ceramics, cemented carbide, powder metallurgy and other powder briquetting is a multi station (7-10 stations) rotary working mode with two-way upper and lower manufacturing and one-time pressing. The traditional driving mode of this type of press is After power on, the motor directly drives the worm to rotate, and then drives the press to rotate to achieve the purpose of pressing products. The disadvantage is that the starting of the press needs to overcome a lot of pressure, resulting in a large power consumption of the motor; in addition, the torque between the worm wheel and the worm is also large, and long-term use has a great impact on the service life of the parts The transmission of worm gear and worm gear is driven to achieve the same effect, save power and prolong the service life of transmission system accessories.
In view of the problems existing in the prior art, the utility model aims to provide a multi position rotary automatic powder press with the function of re pressing, making the density of each part of the powder briquette uniform, good consistency and energy saving. The utility model is an improvement on the structure of the existing multi position rotary powder automatic press. On the basis of the original design, a demoulding roller is added, so that the powder is not only ejected by the demoulding track, but also has a changeable demoulding force. The utility model is composed of a frame, a driving unit, a main shaft, a secondary shaft, a track, a feeder, a preloading wheel set, a main pressure wheel set, a demoulding wheel, an upper die plate, a female die plate, a lower die plate and an adjusting mechanism. The machine base is located at the bottom of the whole machine. The main shaft and auxiliary shaft are vertically installed on the machine base. The track, the lower die plate, the female die plate and the upper die plate are respectively fixed on the main shaft from bottom to top. The upper die plate, female die plate and lower die plate are respectively fixed on the upper die plate, female die plate and lower die plate. A feeder is installed on the upper part of the whole machine to send the powder to the female die plate through the hose, The upper pre pressing wheel and the upper main pressing wheel correspond to the pre pressing die and the upper main pressing wheel respectively, which are installed on the bracket fixed on the frame. The lower pre pressing wheel and the lower main pressing wheel correspond to the pre pressing die and the main pressing die respectively, and are installed on the track. The track formulates the motion curve of the lower die, and sets the pressing curve by it. A height adjusting mechanism composed of a pair of worm gear and rising screw is arranged at the bottom of the lower pre pressing wheel and the lower main pressure wheel. Using the utility model, firstly, the powder is transmitted to the mold cavity of the female die plate by the feeder through the conveying hose, and the driving unit of the machine drives the three die discs (upper die disc, female die disc and lower die disc) to rotate synchronously around the main shaft at the set speed. After the powder is pressed twice by the pre pressing wheel set and the main pressing wheel set in the female mold cavity, the powder is pressed into powder blocks, and then comes out of the female mold cavity to complete the pressing process of a product. The utility model has the function of re pressing, which is an automatic press with simple structure and complex action. The multi position rotary structure determines that it has high productivity and can produce about 100 products per minute. Because of the new transmission mode adopted by the invention, the press has the energy-saving effect, which is in line with the magnetic materials, ceramic materials, cemented carbide, powder metallurgy, etc Automatic forming of briquette and other fields.
