Embodiment 1

[0050] Embodiment 1: An insulating and vibration-damping layer 1 with a length of 100 mm, a width of 30 mm, and a thickness of 1 mm is selected. Cut 2075 metal wires 2 with a length of 2.6 mm and a diameter of 0.5 mm, and then insert the metal wires 2 evenly and vertically into the insulating vibration-damping layer 1, the distance between two adjacent metal wires 2 is 1.2 mm, and make The length of the two ends of the metal wire 2 respectively exposed to the insulating and damping layer 1 is 0.8 mm, so that the sum of the cross-sectional areas of the metal wire 2 accounts for about 14% of the upper surface area of ​​the insulating and damping layer 1 . Then place the lower steel plate 4 horizontally, and place the insulating and damping layer 1 on the lower steel plate 4, then heat the insulating and damping layer 1 inserted with the metal wire 2 to 50 degrees until it is in a semi-melted state, and then place the upper steel plate 3 is covered on the upper surface of the ins...

Embodiment 2

[0051] Embodiment 2: An insulating and vibration-damping layer 1 with a length of 100 mm, a width of 30 mm, and a thickness of 1 mm is selected. Cut 750 copper wires with a length of 3.4 mm and a diameter of 1 mm, and then insert the copper wires evenly and vertically into the insulating vibration-damping layer 1, the distance between two adjacent copper wires is 2 mm, and make the two copper wires The length of the ends exposed to the insulating and damping layer 1 is 1.2 millimeters, so that the sum of the cross-sectional areas of the copper wires accounts for about 20% of the surface area of ​​the upper layer of the insulating and damping layer 1. Then place the lower steel plate 4 horizontally, and place the insulating and damping layer 1 on the lower steel plate 4, then heat the insulating and damping layer 1 inserted with copper wires to 80 degrees until it is in a semi-melted state, and then place the upper steel plate 3 It is covered on the upper surface of the insulat...

Abstract

The invention provides a spot-welded conductive automobile vibration reduction plate and a manufacture method of the spot-welded automobile vibration reduction plate. The vibration reduction plate comprises an upper-layer steel plate (3) and a lower-layer steel plate (4), wherein an insulating vibration reduction layer (1) is arranged between the upper-layer steel plate (3) and the lower-layer steel plate (4). The invention is characterized in that a metal wire (2) is distributed in the insulating vibration reduction layer (1), and two ends of the metal wire (2) are respectively contacted with the upper-layer steel plate (3) and the lower-layer steel plate (4). The invention is simple in structure and manufacture technology, a steel wire is inserted into an insulating viscoelastic resin layer, so that the upper-layer steel plate and the lower-layer steel plate are conductive, the whole structure of the viscoelastic resin layer can not be damaged at the same time, the parts of an automobile body can be preferably welded, and the vibration reduction and noise reduction effects of the vibration reduction plate can be guaranteed, so that the vibration reduction plate is wide in use range.

Description

technical field [0001] The invention relates to a damping plate and a manufacturing method, in particular to a conductive automobile damping plate and a manufacturing method. Background technique [0002] At present, the known damping panels for automobiles are generally composed of three layers of plates, that is, an upper layer of steel plate, a middle layer of non-conductive viscoelastic resin material layer, and a lower layer of steel plate. The middle layer of non-conductive viscoelastic resin material layer bonds the steel plates on the upper and lower sides together to form a damping plate. The purpose of using the damping plate is to reduce the vibration of the automotive structural parts. [0003] The principle of damping plate vibration reduction: When the mechanical structure is subject to bending vibration and the viscoelastic resin material layer is elongated, the upper and lower steel plates prevent the viscoelastic resin material layer from elongating; on the...
