Abstract
The utility model provides an automobile muffler inner tube is with expand tube chucking structure, include the trachea and install the baffle at the trachea outer wall, the trachea is the pipe structure, and the trachea perisporium has two to past bellied boss, and the boss is arc or square structure, thereby the baffle card is gone into to form interference fit between two bosss and is linked together with the trachea. The utility model discloses an at the inside expand tube chucking structure that uses of silencer inclusion, can save the process of clearance welding slag, stopped the phenomenon because of the silencer abnormal sound that the welding slag produced, owing to abandoned the welding mode in addition, so can save the welding wire in the manufacturing process, reduced manufacturing cost, the expand tube chucking mould production efficiency of adoption is higher than the welding, and process stability is higher.
Description
Technical Field
The utility model relates to an automobile muffler technical field especially relates to an automobile muffler inner tube is with bloated pipe clamping structure.
Background
The automobile silencer is a common component part of an automobile, is beneficial to reducing noise pollution in the driving process of the automobile, and is manufactured by utilizing the principle of sound wave superposition interference. The automobile muffler can be divided into three types, namely a reactive muffler, a resistive muffler and an impedance composite muffler according to the silencing principle and structure. The muffler for an automobile can reduce exhaust noise of an engine and enable high-temperature exhaust gas to be safely and effectively discharged. The silencer is used as a part of an exhaust pipeline and is required to ensure smooth exhaust, small resistance and enough strength.
Under the prior art condition, the structure that generally adopts is that silencer and exhaust duct adopt the baffle to separate, generally adopts the welded mode to be connected between exhaust duct and the baffle, but adopts this kind of welded connection mode, the problem that the welding slag dropped appears easily in the use for the phenomenon of abnormal sound appears in the silencer, and this kind of welded mode needs to adopt special equipment to accomplish in addition, and the cost is higher.
Disclosure of Invention
The utility model relates to a to the not enough of above-mentioned technique, through designing a car silencer inner tube with bloated pipe chucking structure, can save the process of clearance welding slag, solve the phenomenon because of the silencer abnormal sound that the welding slag dropped the production.
The utility model provides a technical scheme as follows: the utility model provides an automobile muffler inner tube is with expand tube chucking structure, includes the trachea and installs the baffle at the trachea outer wall, the trachea is the pipe structure, and the trachea perisporium has two to past bellied boss, and the boss is arc or square structure, thereby the baffle card is gone into to form interference fit between two bosss and is linked together with the trachea.
Furthermore, the clapboard is in a disc shape, the axis part of the clapboard is bent downwards to form a through hole, and the air pipe passes through the through hole.
Furthermore, the baffle includes the base plane and the inside bending portion that forms of base plane, and the portion of bending includes the connection curved surface and connects in the backing sheet of connection curved surface lower extreme.
Furthermore, the length of the bending part is slightly shorter than the distance between the two bosses.
Compared with the prior art, the utility model discloses an at the inside expand tube chucking structure that uses of silencer inclusion, can save the process of clearance welding slag, solved because of the welding slag phenomenon of the silencer abnormal sound that drops the production, owing to abandoned the welding mode in addition, so can save the welding wire in the manufacturing process, reduced manufacturing cost, the expand tube chucking mould production efficiency of adoption is higher than the welding, and process stability is higher.
Drawings
FIG. 1 is the structure diagram of the pipe expansion clamping structure for the inner pipe of the automobile muffler.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and features in the embodiments and embodiments in the present application can be combined with each other without conflict.
As shown in fig. 1, an automobile muffler inner tube is with bloated pipe chucking structure, includes trachea 1 and installs baffle 2 at 1 outer wall of trachea, trachea 1 is the pipe structure, and 1 perisporium of trachea has two to bellied boss 11, and boss 11 is arc or square structure, thereby baffle 2 card is gone into to form interference fit between two boss 11 and is linked together with trachea 1.
Baffle 2 is the disc shape, and the axle center position of baffle 2 is bent downwards and is formed a through-hole, and trachea 1 passes from the through-hole, and is specific, baffle 2 includes the portion of bending that base face 21 and base face 21 inboard downwarping formed, and the portion of bending is including connecting curved surface 22 and connecting in the backing sheet 23 of connecting curved surface 22 lower extreme, and the length of the portion of bending is slightly less than the distance between two bosss 11 for the portion of bending can be blocked between two bosss 11.
The manufacturing method of the utility model is as follows: firstly, the air pipe 1 penetrates through the through hole of the partition plate 2, and then the two bosses 11 are extruded out of the two sides of the bending part through a special tool, so that the partition plate 2 is clamped between the two bosses 11 to form interference fit and is fixedly connected with the air pipe 1.
The utility model discloses an at the inside expand tube chucking structure that uses of silencer inclusion, can save the process of clearance welding slag, stopped because of the welding slag phenomenon of the silencer abnormal sound that drops the production, owing to abandoned the welding mode in addition, so can save the welding wire in the manufacturing process, reduced manufacturing cost, the expand tube chucking mould production efficiency of adoption is higher than the welding, and process stability is higher.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
Claims (4)
