Top arrangement type accurate mechanical synchronous full-load blanking and buffering device

Abstract

The invention relates to a top arrangement type accurate mechanical synchronous full-load blanking and buffering device, in particular to the technical field of a large-scale hydraulic machine, which comprises an upper cross beam and a sliding block bracket, wherein the upper cross beam is provided with two through holes; guide pillars are sheathed in the through holes; the upper end of each guide pillar is connected with a buffering nut, and the lower end of the guide pillar is connected with the sliding block bracket through a locking nut and is provided with a radial groove; flat keys are arranged in the radial grooves; the exterior of each guide pillar is respectively sheathed with an adjusting screw rod, a hollow thread sleeve and a worm wheel; a reduction motor is arranged between the two guide pillars; the two output shafts of the reduction motor are connected with a synchronous transmission shaft through a coupler; the synchronous transmission shaft is connected with a worm rod; the worm wheel is engaged with the worm rod; a buffering oil cylinder is arranged between the adjusting screw rod and the buffering nut; the upper cross beam is connected with two guiding brackets;and the adjusting screw rod is connected with a guiding flat key, and the other end of the guiding flat key is arranged in the guide grooves of the guiding brackets. By using the device of the invention, the vibration and blanking noise of the hydraulic machine is greatly reduced, and the service life of the hydraulic machine and a mould is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of a large hydraulic press, in particular to a buffer device for full-load blanking of a slide block on a large hydraulic press body. Background technique [0002] With the rapid development of the modern machinery industry, hydraulic presses as forging equipment are also moving towards large-scale, automated, precise and intelligent, and need to meet the development requirements of low-carbon economy and green manufacturing technology. In realizing automation, While reducing the labor intensity of workers, it is even more necessary to avoid the harm caused by strong noise pollution during equipment operation. Since the hydraulic machine will vibrate the whole body and produce powerful punching noise when punching and blanking, two small-load buffer cylinders and adjusting screw devices are added on both sides of the slider of the traditional large-load punching hydraulic machine to realize the buffering fun...

Problems solved by technology

Because the intermediate transmission process of this transmission device is relatively complicated, the transmission gap between the chain and the sprocket is relatively large, and the transmission error of the two screws is very different when the positive and negative rotation is added, and the chain jumps violently during high-speed transmission. The deformation is very large during torque. These factors not only affect the transmission accuracy, but also it is difficult to ensure that the adjusting screws on both sides of the adjusting device are at the same level, so there is an overload phenomenon in the screw at the moment of buffering, resulting in the bias of the slider. Strong impact and vibration, so it must be adjusted repeatedly to achieve the desired effect, labor-intensive, time-consuming and labor-intensive, and affects the service life of the press and mold at the same time, it is not suitable for the production requirements of multiple varieties and small batches

In addition, due to structural reasons, this kind of device is not suitable for presses that need to change molds or feed materials from the side, and the application range is limited
