Description

Technical Field

[0001] The utility model belongs to the technical field of muffler processing, and in particular relates to a muffler pipe expansion device. Background Art

[0002] The car muffler is a part used to reduce the noise generated by the engine of a motor vehicle. Since the difference in the length of the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere with each other when superimposed and cancel each other out, thus reducing the sound intensity and reducing the sound, thus achieving the effect of silencing. The pipe diameters of different parts of the muffler are different. During the processing, it is often necessary to use a flaring device to flare the pipe port.

[0003] The Chinese patent with application number CN202120926716.X discloses a pipe expanding device for muffler processing, a detachable plate is connected to the middle part of the right end face of the sliding seat, and a expanding die is fixedly connected to the right end face of the detachable plate. A clamping block is arranged on the base on the left side of the standing seat, and the left end of the adjusting screw rod is rotatably matched with the clamping block. The spatial positions of the upper and lower clamping blocks correspond to each other, and a sliding groove is opened on the end faces of the opposite sides of the two clamping blocks, and a clamping seat is slidably assembled in each sliding groove. The clamping seat is slidably assembled in the sliding groove through the cooperation of the slide rail and the groove. A short screw rod is fixedly connected to the middle part of the left and right end faces of the clamping seat, and the short screw rod extends out from the waist-shaped hole on the corresponding side, and a locking nut is threadedly connected to one side of the short screw rod extending out of the waist-shaped hole. A plurality of clamping grooves with arc-shaped structures are evenly opened on the end faces of the opposite sides of the two clamping seats, and the diameters of the clamping grooves on the clamping seats are different, and the clamping grooves on the upper and lower sides correspond one to one.

[0004] However, the expansion devices currently on the market have certain defects during use. Their structures are complex, their operations are complex, and most pipe expansion devices cannot perform continuous expansion operations. The efficiency of the muffler pipe expansion processing is not high enough. Therefore, an improved muffler pipe expansion device is designed. Utility Model Content

[0005] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a muffler pipe expansion device to solve the above-mentioned problems in the background technology.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0042] In this example, the clamping mechanism 3 includes: a mounting plate 31 connected to the top of the two side plates 2, and a support seat 34 is arranged opposite to the mounting plate 31 at intervals below the mounting plate 31; a first linear actuator 32 vertically mounted on the mounting plate 31, and an upper clamping block 33 is connected to the movable end of the first linear actuator 32; a lower clamping block 35 fixedly arranged on the top of the support seat 34, and the upper clamping block 33 is driven by the first linear actuator 32 to approach the lower clamping block 35, thereby forming a opposite clamping for the muffler pipe 01 on the lower clamping block 35. The lower clamping block 35 of the clamping mechanism 3 is fixedly arranged on the support seat 34, and the upper clamping block 33 is connected to the movable end of the first linear actuator 32.

[0046] Working principle: the unprocessed muffler pipe fitting 01 is transferred from one side of the first transmission rack 5 to the lower clamping block 35, and after the expansion process, it rolls onto the second transmission rack 6 for subsequent further processing. Specifically, since the transmission channels of the second transmission rack 6 and the first transmission rack 5 are both inclined, the muffler pipe fitting 01 on the first transmission rack 5 can automatically roll to the lower clamping block 35, and the top block 37, driven by the second linear actuator 36, extends from the through-hole groove and lifts the muffler pipe fitting 01 on the first transmission rack 5, so that the muffler pipe fitting 01 rolls into the slot of the lower clamping block 35, and then the upper clamping block 33, driven by the first linear actuator 32, clamps the muffler pipe fitting 01 in the opposite direction, and the third linear actuator 41 drives the expansion die 42 to gradually extend into the muffler pipe fitting 01, thereby gradually expanding the muffler pipe fitting 01 to realize the expansion process.
