Abstract
The invention relates to a manufacturing technology of an engineering machinery component, in particular to a manufacturing method of a spiral feeding vane and a manufacturing device of a spiral conveying device, wherein, the method comprises the following steps: a. a metal plate is cut into annular metal pieces; b. each annual metal piece is cut with a fracture along the radial direction, and the upper fracture surface and the lower fracture surface of the fracture are respectively staggered up and down so as to form a structural unit; c. the fracture surfaces of a plurality of structural units are connected and welded into a whole end to end; d. the ends of two structural units which are connected end to end are fixed at two stretching ends of a linear drawing and stretching device, and a radial tensile force is exerted on a group of structural units which are welded into a whole so that the radial direction of the structural units is stretched and deformed to form a whole spiral feeding vane naturally. The device and the method can weld the cut annual metal pieces in sequence, stretch and shape the metal pieces into complete spiral feeding vanes again, have simple manufacturing technique and small equipment investment and reduce production cost.

Technical field
The present invention relates to the manufacturing technology of engineering mechanical components, relate to spiral feeding blade manufacture method and manufacturing installation in a kind of screw conveying device.
Background technology
Screw conveying device is the device that often uses in the material-transporting system of kind engineering machinery, its structure is that a mandrel is set in cylindrical tube, on on the mandrel, spiral feeding blade is set, when mandrel rotates, material is pushed to a direction by spiral feeding blade.Spiral feeding blade in the existing equipment adopts particular manufacturing craft moulding piecemeal usually, is welded on piecemeal on the mandrel again, and its manufacturing process complexity, equipment have high input, manufacturing cost is higher.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of manufacturing process is simple, the spiral feeding blade manufacture method and the manufacturing installation of low cost of manufacture.
Spiral feeding blade manufacture method of the present invention may further comprise the steps:
A. the sheet metal stamping-out is circularized sheet metal;
B. each annular sheet metal is gone out a fracture along its radial shear, and, form a construction unit two upper and lower staggering of section of incision position;
C. the section of a plurality of construction units is spliced from beginning to end and be welded as a whole;
D. end that will two construction units of head and the tail is fixed on two ends that stretch of straight line traction stretching device, and the one group of construction unit that is welded as a whole is applied an axial pulling force, makes its axial elongation distortion and formation whole piece spiral feeding blade naturally.
In the said method, some construction unit be sheared the position, one section solid material is cut off and is formed a fan-shaped breach, each construction unit between two construction units of head and the tail promptly adopts this construction unit that has sector notch.
Spiral feeding blade manufacturing installation of the present invention includes a fixed frame, framework upper is installed the power set that can produce to upper pulling force, the lower end of power set connects a upper fixed seat, fixed frame below the upper fixed seat is provided with a lower fixed seat of fixedlying connected with fixed frame, is connected with upper connector and following connector on upper fixed seat and the lower fixed seat respectively.Also can be connected with one section sleeve that vertically is provided with on the described upper fixed seat, the sleeve lower end is provided with opening, can insert for the mandrel of screw conveying device.Described power set are an electric block.
Apparatus of the present invention and method can be welded the annular sheet metal after shearing successively, and drawing and forming is complete spiral feeding blade again, and its manufacturing process is simple, the equipment input is little, has reduced manufacturing cost.
