Abstract
The utility model relates to a pot holder of a silencer for an automobile engine, which consists of a layer of aluminum foil, a layer of glass wool and a layer of non-woven fabrics, wherein the glass wool is arranged between the aluminum foil and the non-woven fabrics, the peripheral edge of the pot holder is provided with a press edge, and the depth of the press edge is less than that of the pot holder. The pot holder with the structure can simplify the manufacture technology of the pot holder and can reduce the manufacture cost of the pot holder.
Description
Technical field
The utility model relates to the part in the motor car engine, particularly the thermal insulating pad in the motor car engine silencing apparatus.
Background technique
The thermal insulating pad of existing motor car engine silencing apparatus mainly contains two kinds, and a kind of is the integrated type thermal insulating pad, by the disposable impact briquetting of aluminium plate; Another kind is the assembly type thermal insulating pad, be with behind stamping forming aluminium plate and glass wool, the nonwovens hot-forming (shape and the aluminium plate of glass wool, nonwovens are complementary), fit together (bound edge mainly plays the effect that prevents that glass wool from spilling, anti-sealing enters glass wool and reinforces thermal insulating pad) by aluminium sheet, glass wool and the nonwovens of manual bound edge after again moulding.The manufacturing process of monolithic construction thermal insulating pad is simple, and part thickness is thin, but cost of parts is higher.The manufacturing process complexity of modular construction thermal insulating pad, minimum needs two molds though Master Cost is minimized, have increased die cost, and adopt manual bound edge to make the conformity of part poor, and joint-cutting is arranged, and are prone to stress and concentrate and problems of crack.
Summary of the invention
The purpose of this utility model provides a kind of silencing apparatus thermal insulating pad, with the manufacturing process of simplifying thermal insulating pad and the manufacture cost that reduces thermal insulating pad.
Silencing apparatus thermal insulating pad described in the utility model, be made of one deck aluminium, one deck glass wool and layer of non-woven fabric, glass wool is between aluminium and nonwovens, and described aluminium is an aluminium foil, be provided with flanging in the thermal insulating pad edge, the thickness of flanging is less than the thickness of thermal insulating pad.
As optimal way, the thickness of flanging is 1/4～1/3 of thermal insulating pad thickness.
Because aluminium foil is very thin, thus this silencing apparatus thermal insulating pad when moulding, aluminium foil, glass wool and nonwovens from top to bottom can be placed stack after, be put into once hot pressing in the hot pressing die.
Hot-forming back glass wool will be by sclerosis to a certain degree, because the thickness of thermal insulating pad edge flanging is less than the thickness of thermal insulating pad, so the hardenability of the glass wool in the flanging is greater than the hardenability of the glass wool at other position of thermal insulating pad, the aluminium foil of flanging place, glass wool and nonwovens tight bond are integral, glass wool pack in the thermal insulating pad is blocked, can effectively be played the effect that prevents that glass wool from spilling, anti-sealing enters glass wool and reinforces thermal insulating pad.
At silencing apparatus thermal insulating pad described in the utility model owing to replaced existing aluminium plate with aluminium foil, and be provided with flanging in the thermal insulating pad edge, adopt once hot pressing, the impact briquetting of aluminium plate and the operation of manual bound edge have been saved, thereby simplified the manufacturing process of thermal insulating pad, reduced the manufacture cost of thermal insulating pad.
