Description

Automatically divide the steel device

Technical field

The utility model relates to the branch steel device behind rod, the section steel straightening, belongs to the rolling machinery technical field.

Background technology

The rod section bar will be aligned through the aligning operation behind rolling finishing, and the section bar behind the aligning is delivered to the check stand by rollgang and tested, and the section bar that is up to the standards enters stacking by next rollgang and ties up operation, and defective section bar then needs letter sorting in time to pick out.At present, the check stand of middle-size and small-size steel rolling mill adopts chain-type to move the steel testbed more, divides steel work to be finished by manually-operated.People's work point steel labour intensity is big, divide steel speed slow, and unsafe factor is many.Limited the processing speed of preorder aligning operation, and the middle database storage before the aligning operation is increased.People's work point steel mode has become the restraining factors that whole excellent section bar production efficiency improves, must abandon, so must develop automatic minute suitable steel device.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of automatic minute steel device, to replace backward people's work point steel mode.

The alleged problem of the utility model realizes with following technical solution:

A kind of automatic minute steel device has swing stand 10, hoist cylinder 11 and drive unit in the formation, wherein:

The swing stand comprises swing arm 10-1, conveyer belt 10-2, forward and backward belt wheel 10～3 and 10-4, swing arm rear end and back shaft 10-5 are hinged, front end is for rotating freely end, forward and backward belt wheel lays respectively at the front and back ends of swing arm, and conveyer belt is a closed circular, is looped around on the forward and backward belt wheel;

Hoist cylinder is positioned at the below of swing stand 10, and its piston rod 11-1 and swing arm 10-1 flexibly connect;

Motor 12 in the drive unit is in transmission connection with conveyer belt.

Above-mentioned automatic minute steel device, described conveyer belt 10～2 is spaced by the chain of two closed circulars to be formed, described forward and backward belt wheel 10-3,10-4 should be sprocket wheel mutually, the sprocket wheel fixed interval is on the back shaft 10-5 of swing arm rear end after two, two preceding sprocket wheels are installed in the swing arm front end at interval, and described motor 12 is in transmission connection by back shaft, back sprocket wheel and conveyer belt.

Be being connected of convenient and rollgang, above-mentioned automatic minute steel device, described swing arm 10-1 is a rectangular frame, the rectangular frame rear end is hinged by hinge bar 10-6 and back shaft 10-5, two edges of rectangular frame front end extend to form cantilevered leg forward, and described two preceding sprocket wheels are installed in two cantilevered leg front ends by minor axis 10-7 and minor axis seat 10-8 respectively.

Collect for convenient, above-mentioned automatic minute steel device, described swing arm front end is set up feeder 13.

The swing stand that has conveyer belt that the utility model provides can be in conveyer belt and roller-way etc. to be connected or disconnects two states by drive unit, thereby when defective rolled piece occurring, can realize dividing automatically steel by the swing stand, thereby abandoned the people's work point steel that falls behind, and therefore eliminated people's work point steel to the restriction of straightening processing speed and overstocking of the preceding rolled piece of aligning, help improving Rolling Production efficient, suit in excellent section rolling production line, to install and use.

Description of drawings

Fig. 1 is the utility model structural representation:

Fig. 2 is an A-A profile among Fig. 1;

Fig. 3 is a B-B profile among Fig. 1;

Fig. 4 is the enlarged drawing of overlooking of Fig. 1;

Fig. 5 is to use example schematic.

The specific embodiment

Consult accompanying drawing, the rear end of swing arm 10-1 and back shaft 10-5 are hinged in the utility model, can back shaft be fulcrum rotary oscillation under the driving of hoist cylinder 11, and back shaft is installed in the rollgang by supporting seat 10-9; Conveyer belt 10-2 is a closed circular, is looped around on forward and backward belt wheel 10-3, the 10-4 in the swing arm, and conveyer belt can be in level or heeling condition when swinging with swing arm, and the motor 12 in the swing arm drive device is in transmission connection with conveyer belt.

Still consult accompanying drawing, conveyer belt 10-2 can adopt the chain-type conveyer belt, be spaced by the chain of two closed circulars and form, forward and backward belt wheel 10-3,10-4 should be sprocket wheel mutually, the sprocket wheel fixed interval is connected rotation synchronously after two with bolster 10-5 key on the back shaft 10-5 of swing arm rear end, and two preceding sprocket wheels then are installed in the swing arm front end at interval, the chain of two closed circulars is looped around respectively on the spaced forward and backward sprocket wheel, and motor 12 rotates by back shaft and back chain wheel drive conveyer belt.

Still consult accompanying drawing, swing arm 10-1 can be rectangular frame, can be articulated and connected by hinge bar 10-6 between the rear end of rectangular frame and the back shaft 10-5, two preceding sprocket wheels are installed on two cantilevered leg of rectangular frame front end by minor axis seat 10-8, minor axis 10-7 respectively, have made things convenient for being connected of swing arm and rollgang or testbed etc.

Consult Fig. 5, the utility model can be set up feeder 13 at the front end of swing arm 10, and the defective rolled piece that letter sorting can be picked out is left concentratedly in feeder.
