Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of flaring dies, and more specifically, particularly relates to a convenient flaring die for an automobile exhaust system. Background Technique
[0002] There are multiple functional components such as a three-way catalyst and a muffler assembly in the vehicle exhaust pipe. It involves pipes with different diameters in multiple sections. To ensure reliable connection between them, usually, the end of the small-diameter pipe is expanded to the same thickness as the large-diameter pipe and then welded together. This can improve the sealing performance at the pipe connection and avoid air leakage and noise generation caused by the loosening of the connector.
[0003] Based on the above, the inventor found the following problems: During the processing of the existing flaring die, the staff needs to replace different flaring dies according to different sizes of exhaust pipes. However, during the replacement, the staff needs to hold it by hand and use bolts for connection, and pre-fixation cannot be carried out, which may cause phenomena such as deviation, and thus bring inconvenience to the staff.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a convenient flaring die for an automobile exhaust system is provided, in order to achieve the purpose of having more practical value. Content of the Utility Model
[0005] The purpose and effect of a convenient flaring die for an automobile exhaust system of the utility model are achieved by the following specific technical means:
[0006] A convenient flaring die for an automobile exhaust system includes universal wheels. A support frame is installed at the top of the universal wheels. A group of mounting frames is installed at the top of the support frame. A flaring mechanism is arranged inside the mounting frame. A cylinder is installed on one side of the mounting frame. One end of the cylinder penetrates through the mounting frame and is installed with a connecting piece. A group of limiting mechanisms is arranged inside the connecting piece. An installation groove is formed on the surface of the connecting piece. One end of the connecting piece is connected and installed with a die body.
[0007] Further, the flaring mechanism includes an electric cylinder. A upper fixing piece is installed at the bottom end of the electric cylinder. A lower fixing piece is installed below the upper fixing piece.
[0008] Further, the limiting mechanism includes a spring. A limiting block is installed at one end of the spring. A clamping block is installed at one end of the limiting block. One end of the clamping block penetrates through the connecting piece to the inside of the installation groove.
[0009] Further, an installation block is installed at one end of the die body. A group of clamping grooves is formed on the surface of the installation block.
[0010] Further, the mounting block is installed inside the mounting groove, and the clamping block is installed inside the clamping groove.
[0011] Further, a plurality of groups of first threaded holes are formed on the surface of the connecting member, and second threaded holes are formed on the surface of the mold body.
[0012] Further, a bolt is connected and installed inside the second threaded hole, and one end of the bolt is connected to the first threaded hole.
[0013] Further, a controller is installed at one end of the support frame.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] Through the cooperation between the mounting block, the mounting groove, the clamping block and the clamping groove, when the staff replaces the mold body, the mounting block can be first aligned with the inside of the mounting groove, and at the same time, under the action of the spring, the clamping block will be automatically clamped into the inside of the clamping groove, thereby realizing pre-fixation. After the pre-fixation is completed, the staff can connect the first threaded hole and the second threaded hole through bolts, and then the mold body can be fixed. The operation steps are very simple, effectively avoiding the need for the staff to hold the mold body by hand for bolt connection, indirectly improving the installation efficiency, and this design greatly increases the practicability.
