Spin forming device with internal and external boss belt pulley

Abstract

The invention relates to a spin forming device with an internal and external boss belt pulley, which comprises a worktable (2), an upright post (5) arranged on the worktable (2), upper and middle plates (7) and (8) which are connected with the upright post (5) in turn, a primary oil cylinder (6) arranged on the upper plate, an upper spindle (4) connected with the primary oil cylinder (6), a lowerspindle (3) and an ejecting oil cylinder (11), wherein the lower spindle (3) and the ejecting oil cylinder (11) are arranged on the worktable (2). The spin forming device also comprises spinning toolcomponent (9 and 10) which are arranged on two sides respectively, wherein the component on each side comprises a side cylinder plate (102) and a side cylinder (101); the horizontal guide post (103) of the side cylinder plate (102) is connected with a sliding plate (104); a vertical guide post (109) is arranged in the middle of the sliding plate and is connected with a fixed bracket (108) and a tool holder (106); a tool (107) is arranged in the tool holder (106); and under the action of the side cylinder (101) and a vertical oil cylinder (105), the tool move up and down as well as left and right so as to spin a workpiece on the lower spindle. The device overcomes the drawbacks of material waste, high energy consumption and low efficiency and the like of the conventional processes such as forging, turning and the like. The produced products have the advantages of high precision, high physical and mechanical performance and the like.

Description

Technical field: [0001] The invention belongs to the technical field of mechanical transmission parts manufacturing, in particular to a spinning forming device with inner and outer boss pulleys. Background technique: [0002] Many pulleys have inner and outer bosses, which are mostly used to install bearings and electromagnetic coils, such as common water pump pulleys, electromagnetic clutch pulleys, etc. For a long time, the production process of this kind of products has been completed by using traditional steel mold forging, casting blanks, rough turning, and then finishing turning. The pulleys processed in this way need to remove a lot of material, and not only consume a lot of energy, Waste of material again, inefficiency, poor production conditions. Therefore, the processing technology of producing the belt pulley with inner and outer bosses needs to be improved urgently. [0003] Although plate belt pulley spinning equipment has appeared at present, this equipment c...
