Abstract
The invention provides a high-efficiency coil arc device with time and labor saving, low cost and low failure rate. The high-efficiency coil arc device is characterized in that a lead screw (3) and a thread bushing (5) rotates to drive an upper coiling mould (4) to tightly compress U-shaped steel, and simultaneously a lower coiling mould (11) drives the U-shaped steel to rotate, so as to realize the coiling of the U-shaped steel with different radiuses of curvature and radians.
Description
Technical field
The present invention is a kind of U shaped steel volume arc device, it is characterized in that:, driven the last volume mould and rotate through reductor by motor, realize moving of U shaped steel; Last volume mould compressing and regulating through leading screw and thread bush, realizes rolling the U shaped steel of different curvature radius circular arc.
Background technology
The U shaped steel arch collapsible timbering of colliery underworkings is that U shaped steel is bent into circular arc, assembles with bracket clamp cable, bolt, and wherein circular arc U shaped steel is main and critical component.The making of present domestic U shaped steel arc does not have special equipment or device, and normally according to U shaped steel profile and different curvature radii, casting processing becomes the upper and lower mold of different size, and it is installed on 300 tons and the above hydraulic press makes.There is following problem: a in existing preparation method, does not have isolated plant, and used oil press volume is big, energy consumption is high, and can not mobile operating b, the U shaped steel circular arc of different curvature radius must make with the mold of different size, manufacturing cost is high; The manufacturing of c, a kind of arc section U shaped steel must be through repeatedly press grinding, could moulding, and poor dimensional precision after the moulding, outward appearance out-of-flatness are smooth; D, artificial mobile U shaped steel are wasted time and energy and are very dangerous.
Summary of the invention;
The objective of the invention is in order to overcome all deficiencies of the existing U of manufacturing shaped steel arc section, a kind of U shaped steel volume arc device is provided.
The technical scheme that the present invention adopted is: as upper and lower volume mould, constitute U shaped steel location and travel mechanism after three the rollers processes processing about a, the about 400mm of forging diameter, the heat treatment; The adjustment with radius of curvature of compressing of b, U shaped steel is to adopt a pair of screw pair mechanism, and its screw is become rectilinear motion, and it is upper and lower mobile to roll up mould drives in; The synchronous rotation of c, two last volume moulds is to adopt two modulus parallel-axes gears transmission mechanisms identical with the number of teeth to realize; D, employing motor, reductor mechanism realize power output.
Beneficial effect characteristics of the present invention are: same set of volume mould can roll the circular arc of different curvature radius; Low cost of manufacture; Little, the compact conformation of volume arc device volume, and ability mobile operating; Increased the scope of application; Dimensional accuracy is high after the moulding, and flat appearance is smooth; Production efficiency is high, and labour intensity is low, and handling safety is reliable.
Description of drawings
Fig. 1 is a U shaped steel volume arc device sketch map.
1. motors among the figure, 2. reductor, 3. leading screw is rolled up mould on 4., 5. thread bush, 6, axle 1,7, slide block, 8, axle 2,9, support, 10, base, 11, the last volume mould, 12, gear.
The specific embodiment
Among Fig. 1, reductor (2), support (9) and base (10) be linked together; Last volume mould (4) is installed on the axle 1 (6), and axle 1 (6) two ends are installed in the slide block (7), slide block (7) and leading screw (3) be linked together, through the rotating band movable slider (7) of leading screw (3) in retaining thread cover (5), roll up rectilinear motion about the mould realizations in; Two last volume moulds (11) are installed on the axle 2 (8), and two end supports is in two stands (9); U shaped steel is placed on the two last volume moulds (11), makes the radius of curvature of U shaped steel and the relation of leading screw pitch as required, calculates the distance that volume mould (4) moves up and down, and simultaneously U shaped steel is pressed abd fixed between volume mould (4) and two the last volume moulds (11); Reductor (2) gear of output end is meshed with two gears (12) that are installed in axle 2 (8) one ends, and gear drives two last volume moulds (11) when rotating and rotates in the same way, rotates thereby drive the U shaped steel that compresses above that, realizes roll-forming of circular arc.
Claims (4)
1. a U shaped steel volume arc device is characterized in that, adopts three rollers as upper and lower volume mould; Adopt a pair of screw pair as the guiding mechanism that compresses with radius of curvature; Adopt two moduluses parallel-axes gears identical as transmission mechanism with the number of teeth.
2. a kind of U shaped steel volume arc device according to claim 1 is characterized in that, adopts three rollers as upper and lower volume mould, constitutes U shaped steel location and travel mechanism.
