Description

Technical Field

[0001] This utility model belongs to the field of muffler flanging technology, and in particular relates to an automated production equipment for automotive mufflers. Background Technology

[0002] The main body of automotive mufflers is generally a hollow cylinder with tapered ends for easy welding to other pipes. To facilitate this welding process, flanging at both ends of the muffler is crucial. Flanging not only enhances the strength and sealing of the connection but also simplifies the installation process.

[0003] However, in the current automotive muffler flanging production process, most equipment relies on two mirror-symmetrically configured cylinders to drive the flanging die head to perform the flanging operation. During this process, if there is a significant difference in the outward extension of the two ends of the muffler, or if there is a large error in the distance between the ends and the flanging die head, it can easily lead to processing errors and affect product quality.

[0004] More importantly, most existing equipment relies on manual operation to pick up and put down the silencer. This not only significantly reduces production efficiency but also increases safety hazards during operation, posing a potential threat to the safety of workers.

[0005] Therefore, it is essential to invent an automated production equipment for automobile mufflers. Utility Model Content

The centering conveyor mechanism has a support frame fixedly installed in the middle, and a limiting cylinder is fixedly installed on the upper exterior of the support frame. A pressing head is fixedly installed at the output end of the limiting cylinder. The pressing head is located above the middle of two mirror-symmetrically arranged support platforms. The support platform is fixedly installed on one side of the centering conveyor mechanism. A flanging die head is fixedly installed at the output end of the flanging cylinder fixedly installed on the support platform. The flanging die head is located on one end of the product. The product is placed on the centering conveyor mechanism.

[0007] Preferably, the alignment conveying mechanism includes side plates, mounting shafts, drive components, chain gears, transmission chains, and placement seats.

Two chain gears are fixedly mounted on each mounting shaft, and transmission chains are assembled on the chain gears. Two transmission chains are provided, and several placement seats are mounted on each transmission chain.

[0008] Preferably, a transmission chain is mounted on two chain gears on the same vertical plane, the two transmission chains are arranged parallel to each other, and the mounting seats installed on the two transmission chains correspond to each other.

[0009] Preferably, both the placement seat and the pressing head are provided with grooves corresponding to the product. The pressing head is located above the middle of the two transmission chains, and the pressing head allows the product to be pressed down and restricted.

[0010] Preferably, a centering plate is fixedly installed above one end of each of the side plates. The centering plate has a "Z" shaped plate structure and is located on one side of the support frame.

[0011] Preferably, the inner surface of the centering plate has two planes and one inclined plane, with the inclined plane located between the two planes. The product end is allowed to smoothly transition between the planes and the inclined plane of the centering plate, and the centering plate allows for the calibration of the two ends of the product.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, through the design of a high-precision centering conveyor mechanism, achieves automatic and accurate transfer of products to the flanging station, effectively solving the processing errors caused by the difference in extension at both ends of the muffler. Simultaneously, the design of the centering plate further improves the centering accuracy of the product. The equipment uses a limiting cylinder and a flanging cylinder in conjunction with the flanging die head to achieve automatic flanging operations at both ends of the muffler. This not only improves production efficiency but also significantly reduces the difficulty and safety hazards of manual operation, ensuring the consistency and stability of flanging quality.

[0021] As attached Figure 1 To be continued Figure 3 As shown:

[0022] This utility model provides an automated production equipment for automotive mufflers, including a centering conveyor mechanism 1, a support frame 2, a limiting cylinder 3, a pressing head 4, a support platform 5, a flanging cylinder 6, a flanging mold head 7, and a product 8. The centering conveyor mechanism 1 has a support frame 2 fixedly installed in the middle, and a limiting cylinder 3 is fixedly installed on the upper exterior of the support frame 2. The pressing head 4 is fixedly installed at the output end of the limiting cylinder 3. The pressing head 4 is located above the middle of two mirror-symmetrically arranged support platforms 5. The support platform 5 is fixedly installed on one side of the centering conveyor mechanism 1. The flanging cylinder 6, which is fixedly installed on the support platform 5, has a flanging mold head 7 fixedly installed at its output end. The flanging mold head 7 is located on one side of the end of the product 8, and the product 8 is placed on the centering conveyor mechanism 1.

[0023] Furthermore, the conveying mechanism 1 includes side plates 11, mounting shafts 12, drive components 13, chain gears 14, transmission chains 15, and placement seats 16. Two side plates 11 are provided, serving not only as supports but also as mounting bases for other components. A support platform 5 is fixedly installed on the outer middle of each side plate 11 to provide stable support during the flanging operation. The two side plates 11 are fixedly connected by a support frame 2 to ensure the stability of the entire mechanism.

[0024] Furthermore, mounting shafts 12 are rotatably mounted at both ends of the two side plates 11. One of the mounting shafts 12 is connected to the output end of the drive component 13, and the entire transmission system is driven by the rotation of the drive component 13. Two chain gears 14 are fixedly mounted on each mounting shaft 12, and the chain gears 14 are connected by a transmission chain 15. There are two transmission chains 15, which are parallel to each other and mounted on two chain gears 14 on the same vertical plane. Several placement seats 16 are mounted on each transmission chain 15 for placing and transmitting the automotive muffler product 8.

[0025] Furthermore, both the placement seat 16 and the pressing head 4 are designed with grooves corresponding to the product 8 to ensure that the product 8 remains stable during transport and flanging. The pressing head 4 is located above the middle of the two transport chains 15, and it can press down and restrain the product 8 when needed to prevent it from shaking or shifting during flanging.

[0026] Furthermore, a centering plate 17 is fixedly installed above one end of each side plate 11. The centering plate 17 adopts a "Z"-shaped plate structure design and is located on one side of the support frame 2. The inner surface of the centering plate 17 has two flat surfaces and one inclined surface. The transition design between these two flat surfaces and the inclined surface allows the end of the product 8 to transition smoothly. The main function of the centering plate 17 is to calibrate the extensions at both ends of the product 8, ensuring that it reaches the optimal positioning state before flanging, thereby improving the accuracy and stability of the flanging operation.

[0027] The working principle is as follows: First, product 8 (i.e., the car muffler) is precisely placed onto the placement seats 16 of the two transmission chains 15 by manual operation, a robotic arm, or other automated mechanism. The placement seats 16 are designed with grooves corresponding to product 8 to ensure that product 8 remains stable during transmission and will not affect the subsequent flanging operation due to shaking or displacement.

[0028] Next, the drive unit 13 begins to operate, driving the connected mounting shaft 12 to rotate. Since each mounting shaft 12 is fixedly mounted with two chain gears 14, and the chain gears 14 are connected through a transmission chain 15, when the mounting shaft 12 rotates, it drives the transmission chain 15 and its mounting seat 16 to move together. In this way, the product 8 is smoothly transported to the flanging station.

[0029] During transmission, the alignment plate 17 plays a crucial role. The inner surface of the alignment plate 17 has two flat surfaces and one bevel. The transition design between these surfaces allows the ends of product 8 to smoothly transition. As product 8 passes over the alignment plate 17, its two ends are automatically aligned, ensuring optimal positioning before flanging.

[0030] When product 8 is conveyed to the flanging station, the limiting cylinder 3 starts to work. It drives the pressing head 4 to press down. The pressing head 4 is also designed with a groove corresponding to product 8 to ensure that it can fit tightly on product 8. The pressing action of the pressing head 4 not only limits the shaking or displacement of product 8 during the flanging process, but also provides stable support for subsequent flanging operations.

[0031] Subsequently, the flanging cylinder 6 begins to operate. It drives the flanging die head 7 to move toward the end of the product 8 and perform the flanging operation. The design of the flanging die head 7 ensures accurate alignment with the end of the product 8 and provides it with a uniform flanging force, thereby guaranteeing the consistency and stability of the flanging quality.

[0032] Finally, after the flanging operation is completed, the drive unit 13 operates again, outputting the flanged product 8 from the flanging station for further processing or inspection. Simultaneously, the new product 8 is placed on the placement seat 16 of the conveyor chain 15, beginning a new round of conveying and flanging operations.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
