Description

Technical Field

[0001] The invention relates to the technical field of automobile component processing, in particular to an automobile muffler production device. Background Art

[0002] The automobile exhaust system is mainly composed of three sections: the head section, the middle section and the tail section. The most important structures include the exhaust manifold, the three-way catalytic converter, the front muffler, the rear muffler, the exhaust tail pipe, etc. Among them, the function of the exhaust manifold is to introduce the exhaust gas in the engine exhaust process into the exhaust system; the function of the three-way catalytic converter is to convert the three harmful gases CO, HC, and NOx in the exhaust into harmless gases such as carbon dioxide, nitrogen, hydrogen and water; the main function of the muffler is to control the exhaust sound. The muffler mainly includes the muffler shell, the inner core, the muffler cotton and the end cover. The forming process of the muffler shell: the plate rolling machine rolls it into a cylindrical shape → the longitudinal seam is butt-jointed → the cylinder is pressed into an elliptical main structure.

[0003] Traditional molding processes are usually time-consuming and inefficient. During the molding process, the shell shape may be inconsistent, affecting product quality. At the same time, in traditional processes, temperature control is often not flexible enough, affecting the softening and curing of materials. The intelligent temperature control system in the solution can effectively adjust hot and cold air to improve molding quality.

[0022] Working principle: First, the device performs forming processing operations on the automobile muffler shell. The overall device structure is installed on the supporting frame. The side positioning mechanism 1 and the side positioning mechanism 2 included in the device can form a rectangular guide roller structure through their own structure to wind the shell raw material sheet into a rectangle, and then use the synchronous anchoring mechanism installed between the side positioning mechanism 1 and the side positioning mechanism 2 to perform multi-point anchoring operations on the rectangular shell raw material sheet in the form of multiple angles, and then use the extension drive mechanism installed on the supporting frame to drive the side positioning mechanism 1 and the side positioning mechanism 2 to move synchronously to both sides, so as to pull the wound rectangular raw material sheet into the final elliptical muffler shell structure. With the displacement of the side positioning mechanism 1 and the side positioning mechanism 2, the synchronous anchoring mechanism also moves synchronously. As the shell is folded, the anchoring element is folded to provide a molding space for the elliptical muffler shell structure. At the same time, the suspension table is installed on the supporting frame in a suspended manner, and the temperature control output mechanism installed on the suspension table can output softening hot air and fixed cold air in two directions respectively. The hot air drives the raw material to soften to quickly form a rectangular structure, while the cold air drives the raw material stretched into an elliptical shape to quickly solidify and form. First, the shell raw material sheet is unrolled by the unwinding wheel installed on the suspension table, and then guided by the guide shaft roller to the side positioning mechanism 1 and the side positioning mechanism 2. The side sliding table 1 included in the side positioning mechanism 1 and the side sliding table 2 included in the side positioning mechanism 2 are arranged on opposite sides of the extension drive mechanism on the top of the supporting frame. The side sliding table 1 and the side sliding table 2 both have a A supporting wall structure, a side guide roller 1 installed on the supporting wall of the side sliding platform 1 and a side guide roller 2 installed on the supporting wall of the side sliding platform 2 are also arranged opposite to each other on both sides, the bottom hanger installed on the side sliding platform 1 is reset and restricted by the reset spring 1 fixed on the positioning column 1, and rotates downward, while the top hanger installed on the side sliding platform 2 is reset and restricted by the reset spring 2 fixed on the positioning column 2, and rotates upward, when the side positioning mechanism 1 and the side positioning mechanism 2 are not unfolded, the bottom hanger and the bottom guide roller utilize the resilience of the reset spring 1 and the reset spring 2 to respectively contact the inclined surfaces of the trapezoidal blocks on both sides included in the synchronous anchoring mechanism, so that the bottom hanger and the top hanger are stationary on both sides of the suspension beam at 45 degrees to each other. On the trapezoidal block, the bottom guide roller installed at the outer end of the bottom suspension rod is placed below the side guide roller 1 and the side guide roller 2, and the top guide roller installed at the outer end of the top suspension rod is placed above the side guide roller 1 and the side guide roller 2. At this time, the side guide roller 1, the side guide roller 2, the bottom guide roller and the top guide roller form a rectangular forming frame for winding the raw material sheet, and the diameters of the top guide roller and the bottom guide roller are half of the side guide roller 1 and the side guide roller 2. The shell raw material sheet guided by the guide shaft roller is wound through the side guide roller 1, the top guide roller, the side guide roller 2 and the bottom guide roller in sequence, and is clamped and fixed by the side clamping roller 1 installed adjacent to the side guide roller 1 and the side clamping roller 2 installed adjacent to the side guide roller 2, so that the raw material sheet is wound into a rectangular structure.The synchronous anchoring mechanism can be used to anchor the raw material sheet. The suspension beam included in the synchronous anchoring mechanism is a suspension beam structure fixed on the supporting frame and located between the side positioning mechanism one and the side positioning mechanism two. The central fixed shaft installed on the suspension beam extends to the inside of the rectangular forming frame formed by the side guide roller one, the side guide roller two, the bottom guide roller and the top guide roller. Multiple groups of synchronous unfolding components are installed on the central fixed shaft in a linear distribution, and a freely slidable top contact rod is embedded inside the central fixed shaft. The traction blocks installed on the top contact rod in a linear distribution are connected with each group of synchronous unfolding components in turn, and the top contact rod contacts the trapezoidal top contact block included in the side positioning mechanism two. The trapezoidal top contact block is fixed to the side sliding frame through the extension frame. The traction arm is on the moving platform two and can follow the displacement movement of the side sliding platform two, and the synchronous expansion component includes multiple groups of circumferentially distributed structural parts, each group of structural parts includes expansion arms and limit rails, and the expansion arms are rotatably installed on the side walls of the central fixed shaft, and the limit rails are also correspondingly installed on the side walls of the central fixed shaft, and a group of rotatably supported traction arms are installed between the expansion arms and the limit rails. The traction arms touch the positioning clips installed inside the limit rails, so that the traction arms can always drive the expansion arms to be arranged vertically on the central fixed shaft, and the positioning clips are fixed to each column of traction blocks of the top contact rod, so that the top contact rod can control the folding of all the synchronous expansion components by pulling the positioning clips, and at the same time, use the elastic force of the limit rails to expand all synchronously, and each group of synchronous expansion components includes The outer ends of the expansion arms are provided with anchoring heads, and multiple groups of expansion arms that are simultaneously distributed linearly in a circular manner can anchor the rectangular raw material blank of the outer shell on the inner side through the anchoring heads installed thereon, so that the wound rectangular raw material blank of the outer shell is fixed as a whole, and gradually forms a preliminary outer shell raw material part in the form of a rectangle, and then the extension drive mechanism installed on the support frame is turned on, so that the side positioning mechanism 1 and the side positioning mechanism 2 start to move synchronously in opposite directions, and the central positioning plate included in the extension drive mechanism is installed on the support frame, and the two ends of the linkage rotating plate installed on the top are respectively hinged with an extension arm, and the side sliding table 1 and the side sliding table 2 are displaced on the limiting slide rail in a manner opposite to each other on both sides, and are respectively connected to an extension arm, and then installed on the support frame. The hydraulic output part on the upper part is started, which generates thrust, drives the side sliding platform 1 to move along the limit slide rail, and starts to drag the connected extension arm on one side to move, and makes the linkage rotating plate rotate. As the linkage rotating plate rotates, the extension arm on the other side is unfolded outward, and pushes the side sliding platform 2 to start moving along the limit slide rail to the other side, driving the side guide roller 1 installed on the side sliding platform 1 and the bottom suspension rod to move to one side, while the side guide roller 2 installed on the side sliding platform 2 and the top suspension rod to move to the other side. At this time, the bottom suspension rod and the top suspension rod will be separated from the trapezoidal blocks installed on both sides of the suspension beam, and driven to rotate inward by the elastic force of the reset spring 1 and the reset spring 2, and the rectangular shell raw material is also dragged and stretched by the displaced side guide roller 1 and the side guide roller 2 at the same time.Finally, the rectangular shell of the muffler is formed. At the same time, the trapezoidal top contact block also moves with the extension frame and the side sliding platform, and the top contact rod is also converted from the inclined surface of the trapezoidal top contact block to the protruding surface to contact. At this time, the top contact rod is also pushed into the central fixed shaft by the protruding surface of the trapezoidal top contact block. At this time, all the synchronous expansion components installed on the central fixed shaft are also folded to make room for the shell stretching. The temperature control output mechanism is synchronously opened when the whole equipment is running. The fan element installed on its output air duct generates wind force and blows it into the cooling air duct installed on the top output part and the heating air duct installed on the side wall output part. After the wind enters the heating air duct, it is heated by the heating element installed inside it and blows to the raw material sheet that needs to be formed into a rectangular shape in the form of hot air to soften it. The wind entering the cooling air duct blows to the elliptical shell raw material stretched later in the form of cold air to accelerate its solidification and molding.

Through the coordinated work of the side positioning mechanism and the synchronous anchoring mechanism, the raw material sheet can be quickly wound from a rectangular shape into the final elliptical shell, which significantly improves the production efficiency;

[0025] 2. The present invention has a precise shape control effect: the synchronous anchoring mechanism can anchor the wound rectangular raw material at multiple points, which improves the stability and accuracy of the molding and ensures the consistency of the geometric shape of the final product.

The equipment can adapt to muffler shells of different specifications and shapes, which increases its application range and meets diversified production needs;
