Abstract

The utility model discloses a keel scale mark rolling mechanism for a keel machine. The mechanism comprises a rolling device and a transmission supporting frame, wherein the rolling device comprises an upper rolling shaft and a lower rolling shaft, the upper rolling shaft and the lower rolling shaft are arranged on the transmission supporting frame, an upper rolling wheel and a lower rolling wheel which are matched are arranged on the upper rolling shaft and the lower rolling shaft respectively, annular stripes are evenly arranged on the outer surface of the upper rolling wheel, guiding raised edges are arranged on the two sides of the lower rolling wheel, protruding points are evenly arranged on the outer surface of the lower rolling wheel, and no protruding point is arranged at the bisection position, the trisection position or the quartering position of the outer surface of the lower rolling wheel in the axial direction of the lower rolling wheel. According to the keel scale mark rolling mechanism for the keel machine, the first pair of rolling wheels in the keel machine is improved, scale marks on a keel are generated automatically by the machine, a light steel keel provided with scale marks can be produced without increasing cost, installation can be conducted directly according to the scale marks on the keel in use, the step that measurement is conducted manually with a ruler is omitted, and construction and installation are facilitated.

Description

Be applied to the keel scale roll press mechanism in keel machine

Technical field

The utility model belongs to lightgage steel joist technical field of processing equipment, relates to specifically a kind of keel scale roll press mechanism being applied in keel machine.

Background technology

Keel machine is that to be with steel be raw material, by continuous cold rolling moulding, produce clod wash, the baking vanish unit equipment of complicated section section bar and different size, the equipment of keel machine forms and mainly comprises feeding machine, guiding frame, roll shaped device, means for correcting, fixed ruler cutting device, material receiving desk and electrical control part.

Lightgage steel joist is a kind of New Building Materials, it is that to take the continuous hot galvanizing strip of high-quality be raw material, metallic framework for building by the moulding of keel machine continuous cold rolling, along with the development of China's modernization construction, lightgage steel joist is widely used in the places such as hotel, terminal, Che Yunzhan, recreation ground, market, factory.The lightgage steel joist of being produced by keel machine in prior art is not with scale conventionally on keel, and keel are in use conventionally by manually measuring the length of required keel with chi, and this method not only wastes time and energy, and accurate not, is not easy to construction and installs.So need now a kind of keel scale roll press mechanism that can be applied in keel machine badly, this mechanism can extrude accurate scale at keel top roll, save step, constructability and the installation of manually with chi, measuring keel.

Summary of the invention

The deficiency that the utility model exists in order to overcome prior art, provide a kind of simple in structure, can make lightgage steel joist carry the keel scale roll press mechanism in keel machine that is applied to of scale.

The utility model is achieved through the following technical solutions: a kind of keel scale roll press mechanism being applied in keel machine, it comprises rolling device and transmission bracing frame, rolling device comprises top roll last item and lower roll last item, top roll last item and lower roll last item are arranged on transmission bracing frame, on top roll last item and lower roll last item, be respectively arranged with topping roll wheel and the bottom roll wheel of mutual coupling, outer surface at topping roll wheel is evenly provided with circular fringes, in the both sides of bottom roll wheel, be provided with guiding convex edge, outer surface at bottom roll wheel is evenly provided with pit projection, bisection at bottom roll wheel outer surface, pit projection is not axially established along bottom roll wheel in trisection or quartering position.

On top roll last item and lower roll last item, be provided with and can take turns to topping roll wheel and bottom roll the positioning adapter of axial location.

Being shaped as of pit projection is circular, square, rhombus or triangle.

The beneficial effects of the utility model are: the lightgage steel joist processing technology of keel machine comprises blowing, lead straight, roll-forming, cut off and rewinding five steps, keel scale roll press mechanism of the present utility model is that the roll-forming step in keel production process is improved, the utility model improves the first breaker roll wheel in existing keel machine, due to the bisection at bottom roll wheel outer surface, pit projection is not axially established along bottom roll wheel in trisection or quartering position, so can automatically generate graduation mark on lightgage steel joist in roll-in process, without increasing any cost, can produce the lightgage steel joist that carries graduation mark, during actual use, can directly install according to the scale on lightgage steel joist, saved the step of manually measuring with chi, constructability and installation more.

Scale on lightgage steel joist is made 10 multiple conventionally, if the external diameter girth of bottom roll wheel is 30cm, in the position of the trisection of bottom roll wheel outer surface along bottom roll wheel axially do not establish pit projection, the lightgage steel joist that roll-in goes out is for every graduation mark of 10cm; If the external diameter girth of bottom roll wheel is 40cm, in the quartering position of bottom roll wheel outer surface along bottom roll wheel axially do not establish pit projection, the lightgage steel joist that roll-in goes out is also every graduation mark of 10cm; Conventionally the tie point that is generally centre keel at 300mm～400mm place in use.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1 to Figure 3, a kind of keel scale roll press mechanism being applied in keel machine, it comprises rolling device and transmission bracing frame 1, rolling device comprises top roll last item 2 and lower roll last item 3, top roll last item 2 and lower roll last item 3 are arranged on transmission bracing frame 1, on top roll last item 2 and lower roll last item 3, be respectively arranged with topping roll wheel 4 and the bottom roll wheel 5 of mutual coupling, outer surface at topping roll wheel 4 is evenly provided with circular fringes 6, in the both sides of bottom roll wheel 5, be provided with guiding convex edge 7, outer surface at bottom roll wheel 5 is evenly provided with pit projection 8, at bottom roll, take turns the bisection of 5 outer surfaces, pit projection is not axially established along bottom roll wheel 5 in trisection or quartering position.On top roll last item 2 and lower roll last item 3, be provided with can to topping roll take turns 4 and bottom roll take turns the positioning adapter 9 of 5 axial location, being shaped as of pit projection 8 is circular, square, rhombus or triangle.

Finally should be noted that; above content is only in order to illustrate the technical solution of the utility model; but not restriction to the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement, does not all depart from essence and the scope of technical solutions of the utility model.
