Abstract
The utility model relates to a helical blade rolling device. The rolling device comprises a base plate, a mandrel and a nut, wherein the mandrel is vertically fixed on the base plate; threads are formed at the upper end of the mandrel; a screw pair is formed to be matched with the nut; one end of a flat steel piece is fixed at the bottom of the nut, and the other end thereof is fixed on the base plate; and the helical motion of the nut enables the flat steel piece to be rolled into continuous helical blades. The helical blade rolling device has the characteristics of high material utilization ratio, simple structure, small size, low cost, no energy consumption, etc.
Description
Technical field
The utility model relates to a kind of conveying worm blade manufacturing installation, is specifically related to a kind of device by winding shaping manufactured helical blade.
Background technology
The spiral external diameter generally is used for the occasion of chemical plant or laboratory mass transport, mixing less than the compact spiral conveyer of 100mm.Because the helical blade external diameter is less than normal, be difficult to single helical blade is welded, and rough, can not satisfy instructions for use; Though and the roll forming method can be produced continuous helical blade, need special equipment, investment is big.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple and practical helical blade rolling device.
The technical scheme that the utility model adopted is: a kind of helical blade rolling device, comprise chassis, mandrel, nut, the mandrel vertical fixing is on the chassis, its upper end is provided with screw thread, match with nut and to form a pair of screw pair, band steel one end is fixed on the nut bottom surface, and an end is fixed on the chassis, and the screw of nut rolls into continuous helical blade with band steel.
The beneficial effects of the utility model are because band steel is directly rolled into helical blade, have the stock utilization height, simple in structure, volume is little, cost is low and do not need characteristics such as the energy.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model helical blade rolling device.
Fig. 2 is the vertical view of the utility model helical blade rolling device.
Fig. 3 is the band steel schematic diagram.
Fig. 1 and sequence number that Fig. 2 marks are described as follows:
1. chassis, 2. bearing pin, 3. split pin, 4. baffle plate, 5. helical blade, 6. mandrel, 7. nut.
The specific embodiment
Figure 3 shows that the band steel that is used to roll helical blade, length should be less than 250mm, and width is less than 25mm, and thickness is less than 2mm, and two ends are drilled with fabrication hole by bearing pin 2 diameter.
As shown in Figure 1 and Figure 2, a kind of helical blade rolling device is made up of chassis 1, mandrel 6, nut 7 and corresponding accessory, and mandrel 6 vertical fixing are on chassis 1, and its upper end processes one section screw thread, and matching with nut 7 forms a pair of screw pair.Nut 7 tops are the hexagonal cylinder, and the bottom is in the form of annular discs, and the center is a screwed hole, and a face down bonding has the two piece baffle plates 4 of spacing greater than band steel thickness on the bottom surface, is drilled with round open-work on the baffle plate 4.Also be welded with the two piece baffle plates 4 of spacing on the chassis 1, be drilled with round open-work on the baffle plate 4 greater than band steel thickness.Bearing pin 2 passes on band steel upper end fabrication hole and the baffle plate 4 fixing with split pin 3 behind the circle open-work; Bearing pin 2 passes on band steel lower end fabrication hole and the baffle plate 4 fixing with split pin 3 behind the circle open-work.
Wrench opening is enclosed within on the hexagonal cylinder of nut 7, turns spanner and drive nut 7 rotations, the screw of nut 7 is wound on band steel on the mandrel 6, forms continuous helical blade 5.
