Embodiment 1

[0063] The hot-melt type damping sheet cooling and punching device of this embodiment, such as figure 1 As shown, it includes an air-cooling mechanism 7, a stamping and cutting device body and a special conveyor belt that passes through the stamping and cutting device body to transmit a hot-melt type damping sheet; wherein: the air-cooling mechanism 7 includes an air-cooling box 71, a blower 73 and Air-cooled conveyor belt 74; blower 73 is fixed in the described air-cooled box 71, and is buckled and placed directly above the air-cooled conveyor belt 74; The melt-type damping sheet 10 is connected, and the hot-melt type damping sheet 10 is transferred to the special conveyor belt 9; the stamping and cutting device body 8 includes two supports 82 on both sides of the special conveyor belt 9, which are laid flat and fixed on the two sides. A stamping table 83 on the side of the support platform 82 and a lifting height adjustment mechanism 84; the stamping table 83 is connected to...

Embodiment 2

[0072] The basic structure of the heat-melt damper cooling and punching device of this embodiment is the same as that of Embodiment 1. The difference and improvement are that the upper part of the air-cooled box 71 is an open opening, and a partition 72 is fixedly connected to the opening to block foreign objects. Drop into the blower 73; the wind direction of the blower 73 directly blows the hot-melt damping sheet 10 downward; the lifting height adjustment mechanism 84 is 4 lifting screws symmetrically arranged at the four corners of the stamping table 83; the special conveying The bottom of the front end of the belt 9 is provided with a damping sheet sensing 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 suc...

Embodiment 3

[0081] The basic structure of the heat-melt type damping sheet cooling and punching device of this embodiment is the same as that of Embodiment 2, and the difference and improvement are that it also includes two sets that are respectively arranged on the front and rear sides of the stamping table 83 and directly above the special conveyor belt 9. Cutting die width adjustment mechanism 85. The ingredients of hot-melt damping sheet 10 include 175 kg of ultrafine light calcium powder with a particle size of 0.5-1 μm, 525 kg of ultra-fine heavy calcium powder with a particle size of 0.5-1 μm, 75 kg of mica fine powder, 70 kg asphalt, 9 kg of asphalt modifiers such as SBS styrene or EVA ethylene-vinyl acetate copolymer, 6 kg of softeners such as vegetable oil, rubber oil, rubber rolling oil, etc., 4 kg of fibers such as hemp fiber, aramid Fiber, wherein: the processing steps of superfine light calcium powder or superfine heavy calcium powder are:

Abstract

The invention discloses a hot-melt damping fin cooling and punching device and a production method thereof and belongs to the technical field of car damping. The hot-melt damping fin cooling and punching device comprises an air cooling mechanism, a punching shearing device body and a dedicated conveying belt which penetrates the punching shearing device body to convey hot-melt damping fins. The air cooling mechanism comprises an air cooling box, an air blower and an air cooling conveying belt. The air blower is fixed into the air cooling box and covers over the air cooling conveying belt. The tail end of the air cooling conveying belt is connected with the dedicated conveying belt through the hot-melt damping fins in the conveying process, and the hot-melt damping fins are conveyed to the dedicated conveying belt. The punching shearing device body comprises supports on the two sides of the dedicated conveying belt, punching tables which are horizontally arranged and fixed to the side faces of the two supports, and lifting type height adjusting mechanisms. The punching tables are connected with cutting dies detachably installed at the bottoms of the punching tables through the lifting type height adjusting mechanisms. Through the hot-melt damping fin cooling and punching device and the production method thereof, the problems that too much burrs are generated on the hot-melt damping fins during shearing, and the service life of the conveying belts is short are solved.

Description

technical field [0001] The invention relates to the technical field of automobile damping, in particular to a cooling and punching device for a hot-melt damping sheet and a production method thereof. 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 compromi...
