Description

Technical Field

[0001] The utility model belongs to the technical field of automobile muffler shells, and in particular relates to a mold device with a stretching structure for producing muffler shells. Background Art

[0002] Automobile mufflers are mainly used to reduce the noise generated by the engine of a motor vehicle when it is working. The principle is that the automobile exhaust pipe is composed of two pipes of different lengths. The two pipes are first separated and then intersected. Since the length difference between the two pipes is equal to half the wavelength of the sound wave emitted by the car, the two sound waves interfere with each other when superimposed and cancel each other out to weaken the sound intensity, thereby reducing the transmitted sound and achieving a silencing effect. During the production and processing of the muffler, the outer shell of the muffler will be made into different shapes, sometimes a nearly elliptical shape.

[0003] In the related technology, a stretching device for the shell of an automobile muffler is disclosed, which comprises a base, a support column is arranged on the top of the base, an elliptical mounting plate is arranged on the top of the support column, a support rod is arranged on the top of the mounting plate, two electric push rods are symmetrically fixed to the top of the support rod, the telescopic ends of the two electric push rods are fixedly connected with a stretching rod, and a rod support is arranged at the bottom end of the stretching rod; the utility model is provided with a shaping process after the stretching of the stretching rod is completed, and the gear meshing drives the turning handle and the winding rod to make an elliptical detour, and the slider on the winding rod slides in the slide groove at the upper end of the mounting plate, thereby realizing the rotation of the winding rod around the mounting plate with an elliptical structure.

[0004] However, the above structure still has some shortcomings. When the device is in use, the structure of the winding rod for elliptical movement is complicated, and the heating rod and the winding rod are clamped to the workpiece by the elastic force of the spring, and the clamping force on the workpiece is unstable.

[0037] By setting the arc-shaped surfaces, the forming of the workpiece can be facilitated when the workpiece is stretched.

[0038] The working principle of the mold equipment with a stretching structure for producing a silencer housing provided by the present utility model is as follows:

[0039] First step: When in use, the workpiece to be processed is sleeved on the two stretching plates 22. The second hydraulic cylinder 21 is started to make the two stretching plates 22 move away from each other. The workpiece is stretched into an ellipse. After forming, the stretching plates 22 are reset. Then, the third motor 19 is started. The third motor 19 drives the threaded rod 17 to rotate. The threaded rod 17 drives the internally threaded slider 18 to move downward. The internally threaded slider 18 drives the mounting frame 8 to move downward. The mounting frame 8 drives the outer correction roller 11 and the inner correction roller 15 to move downward, so that the workpiece is located between the outer correction roller 11 and the inner correction roller 15;

[0040] Second step: Start the first hydraulic cylinder 13. The first hydraulic cylinder 13 drives the rectangular slider 12 to move. The rectangular slider 12 drives the inner correction roller 15 to move through the second rotating shaft 14, so that the inner correction roller 15 and the outer correction roller 11 clamp the workpiece. Start the first motor 5. The first motor 5 drives the gear 6 to rotate. Under the action of the gear ring 3, the two U-shaped mounting plates 4 make an elliptical motion around the elliptical placing table 2;

[0041] Third step: While the U-shaped mounting plate 4 makes an elliptical motion, start the second motor 10. The second motor 10 drives the first rotating shaft 9 to rotate. The first rotating shaft 9 drives the outer correction roller 11 to rotate, so that the outer correction roller 11 rolls on the workpiece, thereby preventing the workpiece from moving along with the outer correction roller 11 and the inner correction roller 15.
