Abstract

The invention relates to a slide block driving device for multi-connecting-rod press machine. The slide block driving device comprises a frame, a motor, a fly wheel, a drive shaft, a transmission member, a slide block and a slide block lead rail. One end of the drive knuckle-lever of the transmission member is connected with and drives a connecting rod by a connection shaft and the other end of which is arranged on the side leg of a crank shaft. The coaxial deceleration gear of the crank shaft gears into a transmission gear arranged on the drive shaft. The slide block driving device is characterized in that the drive shaft is supported below one side of the frame by a bearing; the drive knuckle-lever is supported against the frame by the bearing in the manner of mismatched length; a drive tee is arranged at the other end; an upper fixed block and a lower fixed block are arranged in the drive chamber of the slide block; an upper rubbing block and a lower rubbing block are arranged between the drive tee and two fixed blocks respectively; the sphere of the drive tee is matched with two rubbing blocks and the drive tee can relatively slide between the running-in surfaces of two rubbing blocks; the upper fixed block is assembled by an adjustment bolt that is against the upper fixed block; and the lower fixed block is supported by a strut member that is against the lower fixed block. The slide block driving device has the advantages of stable running, small eccentric load and quick clearance adjustment, and thus is suitable for the such technologies as precise cold forging, cold warm forging, etc.

Description

technical field

[0001] The invention relates to a press machine using a pressure head, in particular to a slider driving device of a multi-link press machine which uses a toggle mechanism to transmit pressure to the pressure head through a thrust member. Background technique

[0002] At present, in the forging press publicly used in the forging industry, the slider drive device mostly adopts a crank slider mechanism, which converts the rotation of the power machine into the reciprocating motion of the slider through the rotation of the crankshaft. A flywheel is also used, and the slider is driven or stopped by engaging and braking the brake clutch to turn or stop the flywheel. For the forging press with this structure, the lifting speed curve of the slider is symmetrical with respect to the bottom dead center, that is to say, the falling speed and rising speed of the slider are the same. In the forging process of the workpiece, the slider is required to execute a very slow ...

Embodiment Construction

[0028] exist figure 1 Among them, a main motor (1) is installed on the bracket on one side of the frame (2) of the press as a power source. The driving force of the main motor (1) is transmitted to a flywheel (5) installed on the drive shaft (7) through a pulley (3) and a transmission belt (4), and a public The brake clutch (6) used is used to connect or disconnect the flywheel (5) from the drive shaft (7).

[0029] image 3 A schematic cross-sectional view of the drive structure of the press slider drive device of the present invention is given. Figure 4 A perspective view of the transmission structure of the drive device of the press of the present invention is given. exist image 3 , Figure 4 Among them, a base end of a transmission toggle lever (8) is rotatably connected to a drive link (10) by a connecting shaft (9), and the other end of the drive link (10) is rotatably mounted on a crankshaft ( 12) on the eccentric crank throw (11).
