Embodiment 1

[0013] Circle-shaped shock pads ( figure 1 Left) is to use 0.1mm steel wire to wind a number of 400mm long dense springs on steel wires with a diameter of 1.2mm, and stretch them into slender springs with equal pitch and a pitch of 2mm, which are used as raw materials for vibration damping pads. Subsequently, these springs are wound on the winding tool, the outer diameter of the winding tool is 1.5 times the inner diameter of the metal damping pad, the winding height is 3 times the actual height, and the outer diameter of the winding is 1.5 times the actual outer diameter. Then, the winding (blank) is removed and passed through the forming device ( image 3 ) bell mouth, introduced into the molding device, pressed into a vibration damping pad consistent with the required size, filled with castor oil, placed in a high temperature box, introduced 100MPa pressure, heated to 200°C, and kept at constant temperature and pressure for 3 hours. Finally, release the pressure, cool down...

Embodiment 2

[0015] Conical shock absorber ( figure 1 Middle) is to use 0.1mm steel wire to wind a number of 400mm long dense springs on steel wires with a diameter of 1.5mm, and stretch them into slender springs with equal pitch and a pitch of 2.5mm as the raw material of the vibration damping pad. Subsequently, these springs are wound on the winding tool, the outer diameter of the winding tool is 1.3 times the inner diameter of the metal damping pad, the winding height is 4 times the actual height, and the outer diameter of the winding is 1.4 times the actual outer diameter. Then, remove the winding (blank), pass through the bell mouth of the molding device, introduce it into the molding device, press it into a vibration damping pad consistent with the required size, pour castor oil, put it in a high-temperature box, introduce a pressure of 100MPa, and heat up to 200°C , constant temperature and constant pressure for 3 hours. Finally, release the pressure, cool down, take out the windin...

Embodiment 3

[0017] Shaped shock pad ( figure 1 Right) is to use 0.15mm steel wire to wind a number of 400mm long dense springs on steel wires with a diameter of 3mm, and stretch them into slender springs with equal pitch and a pitch of 3mm, which are used as raw materials for vibration damping pads. Subsequently, these springs were wound on the winding tool, the outer diameter of the winding tool was 1.7 times the inner diameter of the metal damping pad, the height of the winding was 2.5 times the actual height, and the outer diameter of the winding was 1.7 times the actual outer diameter. Then, remove the winding (blank), pass through the bell mouth of the molding device, introduce it into the molding device, press it into a vibration damping pad consistent with the required size, pour castor oil, put it in a high-temperature box, introduce a pressure of 100MPa, and heat up to 200°C , constant temperature and constant pressure for 3 hours. Finally, release the pressure, cool down, take ...

Abstract

A metallic damping pad is made up of very fine stainless steel wire through winding to obtain many compact springs, crossely winding the springs around die in longitudinal and transverse directions, taking the wound object from die, and die pressing. Its advantages include 3D cellular structure, and high damping effect.

Description

technical field [0001] The present invention is a vibration damping pad used for precision instruments in special industries, such as: equipment containing precision devices on aerospace, aviation, and warships; it can also be used for high-clean production equipment in medicine, chemical, and electronic industries, specifically A metal damping (damping) pad and a manufacturing method thereof. Background technique [0002] Currently commonly used vibration damping pads are divided into rubber and metal springs. For precision instruments in aerospace and aviation, due to the inherent defects of metal springs (the vibration damping effect cannot meet the requirements, the weight and volume are too large), all rubber pads are used. Vibration pads. Although the rubber damping pad has the advantages of low cost and good processability, it also has 1. It is easy to age. Can't meet the requirement of long-term storage, use. 2. High and low temperature failur...
