Abstract
The utility model discloses a kind of cold bed material loading pre-bending device, comprising: lifting device, the front support beam be connected with lifting device and rear support beam, track girder and traversing pre-bending dolly.The utility model advantage provides material loading pre-bending function, product only provided feeding device in the past, not there is pre-bending function, angle steel to be rolled, during the unsymmetrical section bandaging pieces such as rail, during in order to prevent on it cold bed cooling, the moderate finite deformation of generation, affect rolled piece when entering straightener, aligning is not just thus affect product quality.This pre-bending device can pre-bending at any angle, and each pre-bending is cut somebody's hair and to be controlled by separate electrical motor.Pre-bending is wider, better effects if.Realize pre-bending on a large scale, ensure that product quality improves further.
Description
Technical field
The utility model belongs to the association area such as iron and steel, metallurgy, especially relates to cold bed pre-bending device.
Background technology
In recent years, along with the fast development of China's economy, the level of consumption of the people improves constantly, and greatly facilitates civil buildings, the industries such as automobile, skyscraper, railroad bridge flourish.Also just more and more to the requirement of shaped steel product, more product specification, better production assurance is also just more and more stricter.As the important step of in whole piece type steel production line, the serviceability of cold bed material loading pre-bending device directly affects the aligning quality of the product specification of shaped steel and the quality of product.
Cooling bed device is mainly with rolling rear steel plate, bar, tubing.Shaped steel etc., online slowly cooling naturally.Cold bed should have good prebuckling function for the shaped steel of shaped steel especially unsymmetrical section, prevents in natural cooling process because quality everywhere not etc. does not cause occurring irregular flexural deformation.Preventing the rolled piece flexural deformation when entering straightener aligning excessive, causing bad aligning even can not align, the product quality of the rolled piece of impact.Serviceability.
Traditional cold-bed run-in table, only with feeding cart, does not have rolled piece pre-bending function.On rolled piece in cold bed natural cooling process because quality and out-of-shape produce larger flexural deformation.Good straight effect can not be reached after aligning.Have impact on quality.
Summary of the invention
The problem that the utility model type will solve is to provide the pre-bending in advance that a cold bed material loading pre-bending device realizes rolled piece, is particularly suitable for shaped steel, unsymmetrical section section bar.
For solving the problems of the technologies described above, the technical scheme that type of the present invention adopts is:
A kind of cold bed material loading pre-bending device is provided, comprises: lifting device, front support beam, rear support beam, track girder, traversing pre-bending dolly.
Described lifting device front end is provided with hydraulic cylinder, and to realize the elevating function of traversing pre-bending dolly, hydraulic cylinder is connected with front rod, and front rod is connected by pitman shaft with back link.Hydraulic cylinder stretches out, retraction, drives front rod to rise, and front rod rotates through pitman shaft and drives back link synchronously rise or decline.
Described front support beam is connected with front rod by bearing pin, connecting plate, rear support beam is connected with back link by bearing pin, connecting plate, front support beam is connected with track girder closing with bolt by column with rear support beam upper surface, when connecting rod rising or supporting descending beam rise or decline together with track girder;
Motor is equipped with in described track girder side, and motor is connected with sprocket wheel, and electric machine rotation band movable sprocket rotates together.Chain is connected with pre-bending dolly, and drive chain transmission while sprocket rotation, pre-bending dolly moves thereupon, realizes the traversing of dolly.
Motor is equipped with encoder, controls dolly translational speed and displacement.
Described traversing pre-bending dolly comprises: car body, assembling of cutting somebody's hair, and assembling of cutting somebody's hair comprises: cut somebody's hair and wheel.Each pre-bending dolly by Chain conveyer traversing to different distance time, relying on cuts somebody's hair is pushed to diverse location by rolled piece, realizes rolled piece and bends in various degree, achieve the rolled piece pre-bending function before cooling.The flexural deformation produced when decreasing cooling when rolled piece cools.
The utility model advantage: 1 provides material loading pre-bending function, product only provided feeding device in the past, not there is pre-bending function, angle steel to be rolled, during the unsymmetrical section bandaging pieces such as rail, during in order to prevent on it cold bed cooling, the moderate finite deformation of generation, affect rolled piece when entering straightener, aligning is not just thus affect product quality.
2 these pre-bending devices can pre-bending at any angle, and each pre-bending is cut somebody's hair and to be controlled by separate electrical motor.Pre-bending is wider, better effects if.Realize pre-bending on a large scale, ensure that product quality improves further.

Detailed description of the invention
Embodiment 1
Below in conjunction with accompanying drawing, enforcement of the present utility model is described in further detail.
As shown in Figure 1, a kind of material loading pre-bending device, comprising: lifting device, front beam, rear cross beam, track girder, traversing pre-bending dolly.
Described lifting device front end is provided with hydraulic cylinder 1, hydraulic cylinder 1 is connected with front rod 2, front rod 2 is connected by pitman shaft 3 with back link 4, front rod 2 is connected on front support beam 5, back link 4 is connected on rear support beam 6, when hydraulic cylinder stretches out or retract, front support beam 5 and rear support beam 6 synchronously rise or decline.
Described front support beam 5 is connected with front rod 2 by bearing pin, connecting plate, and rear support beam 6 is connected with back link 6 by bearing pin, connecting plate.
Described track girder 8, by column 7, with bolt close be connected respectively at front support beam 5 and rear support beam 6, the same brace summer and rear support beam one lifting.Track girder 8 end is provided with motor 9, motor 9 is connected with sprocket wheel 10, and motor 9 rotating band movable sprocket 10 rotates together.Sprocket wheel 10 is moved together by chain 11 driving-belt motor vehicles bodies 12, and motor 9 afterbody is equipped with encoder, controls car body 12 translational speed and displacement, realizes moving left and right of car body 12.
Described crossbeam pre-bending dolly comprises: car body 12, cut somebody's hair 13, wheel 14.Cut somebody's hair and 13 to be connected with car body 12, wheel 14 moves on track girder 8, and car body 12 is connected with chain 11.Crossbeam pre-bending dolly is by chain 11 transmission moving process, and cutting somebody's hair that car body 12 is installed 13 shifts onto the diverse location such as shaped steel, rail, realizes the pre-bending in advance before cooling.Be unlikely to produce larger flexural deformation after rolled piece cools down, after entering straightener, convenient aligning, obtains better product.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
