Embodiment Construction

[0040]

[0041] The transmission system of the double-crank driven double-point servo press of the present invention comprises a deceleration mechanism, a double-crank mechanism and a crank-link mechanism, such as figure 1 shown.

[0042] The deceleration mechanism is made up of one-stage or two-stage gears, and one-stage synchronous pulley and one-stage gear mechanism can also be selected. The final stage large gear Z4 of the deceleration mechanism is sleeved on the eccentric seat 6 fixed on the fuselage. The deceleration mechanism meets the requirements for the maximum number of strokes of the press under the condition of the rated speed of the servo motor.

[0043] The double crank mechanism includes a large gear, a pin 3, a small connecting rod 2, an output rod 1 and an eccentric seat 6: the pin 3 is fixed on the rim of the large gear, one end of the small connecting rod 2 is hinged to the pin 3 and the other end is connected to the The output rod 1 is hinged, one end of...

Abstract

The invention relates to a double-crank driving double-point servo press which comprises a machine body, a sliding block and two sets of independent driving systems formed by a double-crank mechanism. The two sets of double-crank driving systems are arranged in a beam on the machine body symmetrically, and an output connecting rod of the driving system is hinged to a guiding column on the sliding block. The double-crank mechanism comprises a big gear wheel, a pin shaft, a small connecting rod, an output rod and an eccentric base. The pin shaft is fixedly arranged on an edge of the big gear wheel, one end of the small connecting rod is hinged to the pin shaft, the other end of the small connecting rod is hinged to the output rod, one end of the output rod is hinged to the small connecting rod, the other end of the output rod is fixedly connected with crank shaft supported on the eccentric base movably, and a four bar mechanism is formed by arm length between a pin shaft center and a rotation center of the big gear wheel, the small connecting rod, the output rod and an eccentric distance between the rotation center of the output rod and the rotation center of the big gear wheel. By means of the double-crank driving double-point servo press, the sliding block of the press can obtain the characteristics of large down stroke corners and small back tracking corners, and good forming curves and a remarkable reinforcement effect near a bottom dead center of the sliding block are obtained.

Description

technical field [0001] The invention relates to a double-crank driven double-point servo press, in particular to a double-crank driven double-point servo press, which belongs to the technical field of mechanical presses. Background technique [0002] Since the servo press has the characteristics of good forming performance, simplified structure, energy saving and environmental protection, and easy operation, it has developed rapidly since it came out in the 1990s. The proportion of servo presses in Japan, Europe, America and other countries has reached 25-40% %. In recent years, China has increased investment in the development and research of servo presses, and introduced servo presses with different specifications and different transmission forms. However, the marketization process of the research and development of domestic servo presses is relatively slow, and there have been no reports of batches being introduced to the market so far. The reason is that in addition to...
