Embodiment 1

[0062] The hot-melt type damping plate stamping and cutting device of this embodiment, such as figure 1 As shown, it includes a stamping and cutting device body 8 and a special conveyor belt 9 passing through the stamping and cutting device body 8 to transmit the hot-melt damping sheet 10; wherein: the stamping and cutting device body 8 includes a dedicated conveyor belt 9 The two support platforms 82 on the side, the stamping platform 83 and the lifting height adjustment mechanism 84 that are laid flat and fixed on the sides of the two support platforms 82; the stamping platform 83 is connected to the bottom of the stamping platform 83 through the lifting height adjustment mechanism 84 Die 81 installed. The special conveyor belt 9 is a nylon conveyor belt mainly made of nylon material, the tear strength is greater than 20Mpa, and the elongation at break is greater than 400%, so that it is suitable for the hot-melt type damping sheet 10 of the present invention, and the hot-me...

Embodiment 2

[0071] The hot-melt type damping sheet stamping and cutting device of this embodiment has the same basic structure as that of Embodiment 1, the difference and improvement is that: the lifting height adjustment mechanism 84 is four lifting screws symmetrically arranged at the four corners of the stamping table 83 ; The bottom of the front end of the dedicated conveyor belt 9 is provided with a damping plate induction mechanism 87 . The ingredients of the hot-melt damping sheet 10 include 100 kilograms of superfine light calcium powder with a particle size of 0.5 to 1 μm, 500 kilograms of superfine heavy calcium powder with a particle size of 0.5 to 1 μm, 70 kilograms of mica powder, 60 kilograms asphalt, 8 kg of asphalt modifiers such as SBS styrene or EVA ethylene-vinyl acetate copolymer, 4 kg of softeners such as vegetable oil, rubber oil, rubber rolling oil, etc., 3 kg of fibers such as hemp fiber, aramid fiber.

Abstract

The invention discloses a hot melting damping fin punching and cutting device and a punching method thereof, and belongs to the technical field of vehicle damping. The hot melting damping fin punching and cutting device comprises a punching and cutting device body, and a special conveying belt penetrating through the punching and cutting device body for conveying hot melting damping fins, wherein the punching and cutting device body comprises two support tables on two sides of the special conveying belt, punching tables flatly placed and fixed on the side surfaces of the two support tables, and lifting height adjusting mechanisms; and the punching tables are connected with cutter molds detachably mounted at the bottoms of the punching tables through the lifting height adjusting mechanisms. The punching heights and thicknesses of the cutter molds are adaptively adjusted through the lifting height adjusting mechanisms; and after the hot melting damping fins are effected, the lifting travels can be shortened, and the damage of the conveying belt due to excessive punching is prevented. The device solves the problems of bad burrs in cutting of the damping fins and short service life of the conveying belt.

Description

technical field [0001] The invention relates to the technical field of automobile damping, in particular to a punching and cutting device and a punching method for a hot-melt damping sheet. Background technique [0002] Vibration damping materials are widely used in automotive applications to attenuate road noise and engine vibration and sound. For damping materials, viscoelastic materials are preferred. The damping effect associated with the energy dissipated in a viscoelastic material increases with Young's modulus, as well as the loss factor of the viscoelastic material. Of course, it also increases with the deformation the material is subjected to. Some materials have a high loss tangent but a low Young's modulus, which provide limited damping to the metal plate, and other materials have a high Young's modulus but a low loss tangent (e.g., rubber), which also acts as a damping component and does not Not very good. A good damping material provides a compromise between...
