Embodiment 1

[0018] Special-shaped part expansion device, its structure is as follows figure 1 As shown, it includes a frame 1, a workbench 6, a feeding mechanism—hydraulic system 2, a positioning and clamping mechanism 4, the workbench 6 is fixed on the frame 1, and the positioning and clamping mechanism 4 is fixed on the workbench 4 through the bracket 3. The hydraulic system 2 is installed on the frame 1 under the workbench 6. There are two expansion blocks 10 sliding horizontally on the workbench 6. The two expansion blocks 10 form an expansion block assembly. The center of the expansion block assembly has a tapered hole, and the center wedge Matching, the center wedge is contained in the output shaft of the feeding mechanism-the hydraulic system 2-on the piston rod 5. Each expansion block 10 is equipped with an expansion block guide block 7 and an expansion block reset top block 11 with a back-moving spring on the workbench 6 . Feeding mechanism—hydraulic system 2 includes actuator 2...

Abstract

The invention relates to a bulging device for a special-shaped part; the bulging device is characterized by mainly comprising a framework, an operating platform and a feeding mechanism, wherein the operating platform is fixed on the framework, the feeding mechanism is arranged on the framework, and two or more than two bulging blocks, which can horizontally slide, are arranged on the operating platform; the bulging blocks form a bulging block component; the appearance of the bulging block component takes the shape of a special-shaped opening of the part; a conical hole is arranged in the center of the bulging block component and is matched with a center wedge block; and the center wedge is arranged on an output shat of the feeding mechanism. The bulging device for the special-shaped part, provided by the invention, has the advantages that the part is convenient to clamp and position and has good machining accuracy and high efficiency, and the bulging device can be suitable for multiple products through replacement of modules and appropriate adjustment.

Description

technical field [0001] The invention relates to the expansion and correction of non-circular forming and closed profile of sheet metal parts. Background technique [0002] The transition section of the engine combustion cylinder is made of sheet metal after stamping and forming in half, and then welded, so the deformation is large. In order to ensure the shape of the square mouth, the square mouth needs to be corrected. Due to the large wall thickness of the part, the shape of the square mouth is waist-shaped, and the shape is relatively complicated. It is difficult to manually correct it, and the work intensity of the workers is high. However, using mold calibration on a punching machine requires a complex set of molds, which cannot guarantee quality and is also low in efficiency. With the usual hydraulic system, due to the high pressure of the system, the equipment is bulky and has poor reliability, and generally it can only expand the circular parts. This has affected t...
