Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, a hydraulic plate shearing machine vibration/noise reduction presser foot, including presser foot 1, sliding connection has piston 2 in the presser foot 1, presser foot 1 passes through the fix with screw on leading to the oil groove, thereby hydraulic oil enters into in the presser foot 1 and promotes piston 2, the bottom of piston 2 is connected with pressure head 3, pressure head 3 is main material structure of pressing, play the contact and press the material effect, 1 overcoat of presser foot has connect the extension spring 4 of being connected with pressure head 3, because need the device to reset after unloading oil, consequently, reset through extension spring 4, be provided with between pressure head 3 and the extension spring 4 and fall buffer 5 of making an uproar, thereby because the noise mainly has extension spring 4 to be stretched the vibration production, thereby reduce the noise through falling buffer 5 of making an uproar and reducing.

Further, buffer 5 of making an uproar falls includes the isolator 6 along with 4 spiral settings of extension spring that play, is provided with spring 7 in the isolator 6, and isolator 6 is the rubber material, thereby is convenient for remove along with extension spring 4 and carries out the energy-absorbing, and extension spring 4 is consequently towards its axis compression when being stretched, consequently the isolator 6 also needs to reset after reseing, consequently makes isolator 6 reset through spring 7.

Further, the isolation pad 6 is composed of a plurality of sets of spiral sections 8, because the isolation pad is pressed inwards in the stretching process of the tension spring 4, the isolation pad can be caused to generate the self-pressing condition, the isolation pad is arranged into one section, the problem can be avoided, and sufficient space is reserved through the gaps between the spiral sections 8.

Furthermore, the section of the spiral section 8 is U-shaped, so that the U-shaped section can be better attached to the surface of the tension spring 4.

Furthermore, the springs 7 are provided with two groups, and the two groups are respectively positioned at the upper side and the lower side of the spiral line where the tension spring is positioned, so that the spiral section 8 can be better attached to the tension spring 4 to absorb energy and reduce vibration.

Furthermore, the bottom of the pressure head 3 is connected with a cushion pad 9, and certain energy absorption and vibration reduction are carried out from the pressure head 3.

Furthermore, a space of 0.2mm-0.5mm is arranged between the upper and lower adjacent spiral sections 8, so that the local damage of the spiral sections 8 is prevented from causing protrusion, and the reset of the tension spring 4 is influenced.

The scheme has the following working processes:

hydraulic oil promotes piston 2 and makes pressure head 3 press the material of treating processing, and extension spring 4 is by tensile, and the 5 interior barrier pad 6 of making an uproar that falls when extension spring 4 pulling moves along with extension spring 4, laminates all the time, and when unloading, extension spring 4 resets, and thereby the barrier pad is strutted under spring 7's effect and also resets.

According to the working process, the following steps are known:

the isolation pad 6 is always attached to the tension spring 4, the vibration frequency of the isolation pad is reduced, the isolation pad cannot be in contact with the presser foot 1, and the tension spring 4 directly absorbs vibration reduction when vibration is transmitted to the isolation pad 6, so that noise is effectively reduced, the buffer pad 9 can also reduce partial noise, and the noise reduction effect is improved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
