Embodiment Construction

[0031] see figure 1 , the structural form of the energy-saving double-motor double-station screw press in this embodiment is:

[0032] There are two sets of screw auxiliary mechanisms distributed on both sides of the press, and the two sets of screw auxiliary mechanisms are respectively composed of the first cylinder 7a, the first screw rod 6a, the first slider 8a and the first anti-rotation device 10a. The screw pair mechanism, and the second screw pair mechanism composed of the second cylinder 7b, the second screw mandrel 6b, the second slide block 8b and the second anti-rotation device 10b; the first bevel gear 4a, the second bevel gear 4b, The third bevel gear 4c and the first rotating arm 3a form the first differential gear train, and the first differential gear train takes the third bevel gear 4c and the first rotating arm 3a as input ends, and the first bevel gear 4b is the output end; the second differential gear train is formed by the sixth bevel gear 4f, the seventh...

Abstract

The invention discloses an energy-saving-type double-motor double-station screw press. Two screw pair mechanisms, namely the first screw pair mechanism and the second screw pair mechanism, are distributed on the two sides of the press. A first screw rod in the first screw pair mechanism is driven by a first motor and a second motor through composite motion of a first differential gear chain, and asecond screw rod in the second screw pair mechanism is driven by the first motor and the second motor through composite motion of a second differential gear train. A first sliding block and a secondsliding block in the press symmetrically work. The transmission modes of the second motor and the second differential gear chain are switched by controlling a steering switching device, under the condition that the opposite positions of double cylinders are convenient to adjust, in the press single-cylinder pressing process, the second motor assists the first motor, and the output pressure is increased; and when the press operates in an idle state, the first motor does not work, the middle process with the low power requirement is completed separately by the second motor, energy is saved, andmeanwhile the installed power of a system is reduced.

Description

technical field [0001] The present invention is a double-motor double-station screw press. During normal operation, the left and right mechanisms can work symmetrically. When the left and right mechanisms are unloaded, only one motor works. work at the same time. Background technique [0002] Forming processing is widely used for its advantages of high production efficiency, material saving and high processing quality. Mechanical presses have the advantages of stable transmission and high control precision. With the improvement of factory automation, they will occupy an important position in the press market in the future. [0003] Due to the forming characteristics of the press machine, the motor operates with high energy efficiency only during the short pressing process, and the energy efficiency of the motor is low in other stages, and there is a large amount of energy loss. Among them, when the press is working, the slider frequently rises and falls according to the wo...
