Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product accessories, in particular to a muffler bell mouth forming device. Background Art
[0002] During the processing of the muffler, slotting and flaring operations are required. The traditional method is to first slot the end of the muffler, and then flare it through a hydraulic jacking process. After flaring, welding and assembly are performed. This method requires many steps, and the steps are difficult to form continuity. Transfers are required in the middle, resulting in complicated processes and low efficiency. Summary of the Invention
[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device for forming the bell mouth of a muffler. After adopting the solution, the muffler has a good bell mouth expansion effect and low labor intensity.
[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is: a muffler bell mouth forming device, which includes a frame, wherein a feeding rack is provided in the input direction of the frame, a feeding roller is installed on the top of the feeding rack, a positioning seat is installed on the top of the input end of the frame, a positioning cylinder is fixed in the positioning seat, one end of the positioning cylinder is facing the direction of the feeding rack, and the other end of the positioning cylinder is connected to an expansion cylinder, a pushing cylinder is installed on the feeding rack, a pushing plate is installed on the piston rod of the pushing cylinder, and the pushing plate is facing the positioning cylinder, and an expanding cylinder is horizontally installed on the top of the output end of the frame, and an expanding column is installed on the piston rod of the expanding cylinder, and the center line of the expanding column and the center line of the expansion cylinder are on the same straight line.
[0005] The expansion tube is conical in shape, with its smaller end fixedly connected to the positioning tube and its larger end facing the expansion column. Eight U-shaped cutting grooves are provided on the inner wall of the expansion tube, and the cutting grooves are evenly distributed on the inner wall of the expansion tube.
[0006] The flaring column is conical, with its smaller end facing the expansion tube and its larger end connected to the flaring cylinder piston rod. There are multiple cutting ribs distributed along the center line on the outer cone surface of the flaring column. The cross-section of the cutting rib is triangular, and its tip faces outward.
[0007] The cross section of the cutting rib at the smaller end of the expanded column is smaller than the cross section of the cutting rib at the larger end of the expanded column.
[0008] The number of the cutting ribs is 8, and their positions match those of the cutting grooves.
[0009] After the groove expansion is completed, the piston rod of the expanding cylinder retracts and drives the expanding column away from the expansion tube (making the expanding column leave the muffler), and the pushing cylinder continues to extend to push the muffler out of the positioning tube. The expanding effect of the muffler after adopting this scheme is good and the labor intensity is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention is further described below in conjunction with all the accompanying drawings. The preferred embodiment of the present invention is: The embodiment described in this embodiment with reference to the accompanying drawings is exemplary and is only used to explain this patent, and cannot be understood as a limitation to this patent.
[0014] In the description of this patent, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this patent.
[0015] In the description of this patent, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," and "set" should be understood in a broad sense. For example, they can refer to fixed connection or set, detachable connection or set, or integral connection or set. Those skilled in the art will understand the specific meanings of the above terms in this patent based on the specific circumstances.
[0016] See attached Figure 1 To the attached Figure 3 , described in this embodiment is a muffler bell mouth forming device, which includes a frame 1, wherein a feeding rack 2 is provided in the input direction of the frame 1, a feeding roller 3 is installed on the top of the feeding rack 2, a positioning seat 4 is installed on the top of the input end of the frame 1, a positioning cylinder 5 is fixed in the positioning seat 4, one end of the positioning cylinder 5 is facing the feeding rack 2, and the other end of the positioning cylinder 5 is connected to the expansion cylinder 6, a pushing cylinder 11 is installed on the feeding rack 2, a pushing plate is installed on the piston rod of the pushing cylinder 11, and the pushing plate is facing the positioning cylinder 5, and an expanding cylinder 7 is horizontally installed on the top of the output end of the frame 1, and an expanding column 8 is installed on the piston rod of the expanding cylinder 7, and the center line of the expanding column 8 and the center line of the expansion cylinder 6 are on the same straight line. The expansion tube 6 is conical in shape, with its smaller end fixedly connected to the positioning tube 5 and its larger end facing the flaring column 8. Eight U-shaped cutting grooves 9 are provided on the inner wall of the expansion tube 6, and the cutting grooves 9 are evenly distributed on the inner wall of the expansion tube 6 in equal parts.
[0017] The flaring post 8 is tapered, with its smaller end facing the expansion cylinder 6 and its larger end connected to the piston rod of the flaring cylinder 7. Multiple cutting ribs 10 are distributed along the centerline of the outer conical surface of the flaring post 8. These ribs 10 have a triangular cross-section, with their tips facing outward. The cross-section of the cutting ribs 10 at the smaller end of the flaring post 8 is smaller than that at the larger end. There are eight cutting ribs 10, and their placement matches the position of the cutting grooves 9.
[0018] After adopting the above scheme, the cutting rib gradually expands from the smaller end of the flaring column, thereby forming a gradual cutting effect. The muffler is transported by the feeding roller. After the muffler is facing the positioning cylinder, the pushing cylinder drives the pushing plate to push the muffler into the positioning cylinder, so that the muffler to be opened enters the expansion cylinder. The pushing cylinder remains stationary (positioning the rear end of the muffler), and the piston rod of the flaring cylinder extends to drive the flaring column to move in the direction of the expansion cylinder. The smaller end of the flaring column gradually enters the muffler (the front end of the muffler), and the piston rod of the flaring cylinder continues to move. Under the positioning action of the pushing cylinder, the cutting rib begins to contact the wall of the muffler to groove. At the same time, under the action of the tapered wall of the flaring column, the wall of the muffler after opening is expanded to form
[0019] Trumpet-shaped, after the slot expansion is completed, the piston rod of the expanding cylinder retracts to drive the expanding column away from the expansion tube (so that the expanding column leaves the muffler), and the pushing cylinder continues to extend to push the muffler out of the positioning tube. The muffler expansion effect after adopting this solution is good and the labor intensity is low.
[0020] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any changes made based on the shape and principle of the present invention should be included in the scope of protection of the present invention.
