Embodiment Construction

[0006] Such as figure 1 As shown, this specific embodiment is made up of metal circular sheet material 1 with process hole, rotary wheel 4, rotary wheel 5, upper mold base 6, lower mold base 7, wheel frame 8 and wheel frame 9, and rotary wheel 4 passes through The wheel shaft is installed on the wheel frame 8 to form station a, and the wheel 5 is installed on the wheel frame 9 by the wheel shaft to form station b. The end face of the wheel 4 is a concave arc, and the end face of the wheel 5 is a plane. The metal circular sheet material 1 with the process hole is positioned on the lower mold base 7, and is pressed by the upper mold base 6. Through the radial feed of the station a composed of the wheel 4 and the wheel frame 8, the sheet material 1 is bent and deformed into the pre-shape 2 according to the shape of the end surface of the wheel 4, and the wall thickness is thickened, which can be changed by changing the wheel 4. The size of the radius of the concave arc on the en...

Abstract

The present invention relates to a process for processing a metal plate into a revolving body with a thick wall in rotary extrusion way, which belongs to the field of the mechanical manufacturing engineering, and in particular relates to the manufacturing of a plate processing device and a rotary extrusion mold, and consists of a metal circular plate 1 with a process hole, a rotary wheel 4, a rotary wheel 5, an upper die seat 6, a lower die seat 7, a wheel bracket 8 and a wheel bracket 9, wherein, the rotary wheel 4 is installed on the wheel bracket 8 through a rotary shaft to assemble a work station a; the rotary wheel 5 is installed on the wheel bracket 9 through a rotary shaft to assemble a work station b; the end surface of the rotary wheel 4 is a concave arc; the end surface of the rotary wheel 5 is a plane. The process of the present invention has the advantages such as simple structure, low energy consumption, material conservation, good production safety, convenient commissioning operation, good quality, low cost, etc., which not only changes the traditional processing method, but also thickens the wall of the product, and can be applied to different fields, and is an important process for the processing of the metal plate at present.

Description

Technical field: [0001] The invention relates to the field of mechanical manufacturing engineering, in particular to the manufacture of sheet metal processing equipment and spinning dies. Background technique: [0002] At present, the cylindrical or conical metal products on the market are generally manufactured using traditional stamping and stretching equipment. Stamping and stretching equipment needs to be enlarged, and more processes and molds are required, which not only consumes high energy, wastes materials, the processing safety of the equipment is poor, the surface quality of the product is rough, and it cannot be formed at one time, and the most important point is The wall thickness cannot be increased using conventional stamping and drawing equipment. The quality and safety factor of the final product are greatly reduced. Invention content: [0003] The object of the present invention is to provide a process and method for spinning metal discs into cylindrical...
