The manufacturing method has the advantages of the fastness and the material saving.
Description
Technical field
The present invention refers to a kind of manufacturing method of blade steel plate that can make and save material fast especially about a kind of manufacturing method of blade steel plate.
Background technology
See also Fig. 1, be the schematic diagram of the steel plate of known manufacturing shaping blades, and please consult the stereogram of Fig. 5 simultaneously for blade steel plate.Prior art method is cutting one original steel board 1, reaches the blade steel plate 21 at oblique angle greatly of demand or the blade steel plate 22 at less oblique angle, and the blade steel plate 2 after finishing punching press again forms blade 8.Original steel board 1 punching press by Fig. 1 forms blade 8, dotted line is represented part among the need removal figure, the manufacture method of known manufacturing shaping blades like this is waste material and consuming time taking a lot of work when punching press original steel board 1, especially wastes extremely many materials when punching press forms the blade steel plate 22 at less oblique angle especially.
Therefore, how to invent out a kind of manufacturing method of blade steel plate, the process of blade steel plate reaches fast and the saving material so that make, and will be that the present invention desires actively to inquire into part.
Summary of the invention
Because the shortcoming of above-mentioned known manufacturing method of blade steel plate, it does not reach perfection creator's thoughts, then exhausting the concentrated research of its intelligence overcomes, be engaged in this industry accumulating experience for many years with it, and then develop a kind of manufacture method of blade steel plate, in the hope of reaching fast and the purpose of saving the manufacturing blade steel plate of material.
Main purpose of the present invention is to provide a kind of manufacturing method of blade steel plate, with original steel board heating, rolling, punching press with cut and obtain blade steel plate, so the present invention can reach fast and save the purpose of material ground manufacturing blade steel plate by the automation step for it.
For reaching above-mentioned purpose, the manufacture method of a kind of blade steel plate of the present invention comprises: make steel plate softening through a high temperature furnace heating original steel board; Via rolling device with the original steel board rolling, the thickness in a stage casing that makes this original steel board is less than the thickness at these original steel board two ends, the thick embryo steel plate that formation is made up of two pairs of ventral triangle posts, the minimum place of the thickness in this stage casing forms the drift angle that is connected with each other of these two pairs of ventral triangle posts; By the thick embryo steel plate of stamping machine punching press, form the shaped steel plate that meets precision and dimensional requirement again; Cut shaped steel plate by guillotine at last, separate two pairs of ventral triangle posts in the drift angle place that is connected with each other, obtain two blade steel plates.
As mentioned above, the invention provides one with heating, rolling, punching press and the step that cuts making the method for blade steel plate, and then reach the purpose that the present invention saves material and makes blade steel plate fast.

The specific embodiment
For fully understanding purpose of the present invention, feature and effect, now by following specific embodiment, and cooperate appended graphicly, the present invention is described in detail, illustrate as the back:
See also Fig. 2 and Fig. 3, be respectively the preferred embodiment schematic diagram and the flow chart of the manufacture method of blade steel plate of the present invention.With 1000 centimetres of length, 100 centimetres of width, the original steel board that thickness is 3 to 5 centimetres is sent to airtight vacuum by conveyer belt 32 high temperature furnace 31 heated 12 minutes down in 1000 degree Celsius, the high temperature furnace of airtight vacuum can prevent the blade steel plate oxidation, obtain after the thermoplastic original steel board 11 of high temperature furnace, seize facility 71 (also can by conveyer belt or other conveying device) on both sides by the arms by first and will be sent to rolling device 4 through the thermoplastic original steel board 11 of high temperature furnace, rolling device 4 will be through original steel board 11 rollings of high temperature furnace heating, the thickness that makes original steel board from its two side direction wherein section successively decrease, the thick embryo steel plate 12 that formation is made up of two pairs of ventral triangle posts, the minimum place of thick embryo steel plate 12 stage casing thickness this moment is the drift angle that is connected with each other of two pairs of ventral triangle posts, seize facility 72 (also can by conveyer belt or other conveying device) on both sides by the arms by second thicker embryo steel plate 12 is sent to stamping machine 5, the thick embryo steel plate 12 of stamping machine 5 punching presses makes it become the shaped steel plate 13 that meets institute's required thickness and precision, seize facility 73 (also can by conveyer belt or other conveying device) on both sides by the arms by the 3rd again and be sent to guillotine 6, shaped steel plate 13 is cut into two blade steel plates 2 in the drift angle place that is connected with each other of above-mentioned thickness minimum.See also Fig. 6, the blade steel plate 22 after finishing is struck out blade 8 again, and the blade 8 after finishing makes blade 8 sclerosis through Overheating Treatment again, again via processing grinding make blade sharp and blade 8 finished products to the end.
See also Fig. 4 and Fig. 5 again, be respectively rolling device action schematic diagram of the present invention and rolling device active flank schematic diagram of the present invention.This figure illustrates that rolling device 4 will be through the illustrative view of the original steel board 11 rolling coarse-blank steel plates 12 of high temperature furnace heating; Rolling device 4 includes rolling wheel 41 and following rolling wheel 42 rotates in the opposite direction, and when rotating, two rolling wheels produce 400 tons power, rotation one circle takes one to two second and two rolling wheel outer rim girths cooperate steel plate length to be about 1000 centimetres, but makes two rolling wheels rotate the proper rolling a slice steel plate of a circle.Two upper and lower rolling wheels are designed to tool one projection structure thereon, and it is big than the opening of discharge end in the opening of feed end to be designed to before rolling two rolling wheels, go up the same rate rotation in the opposite direction of rolling wheel 41 and following rolling wheel 42 during charging, and the distance between two projections structure is about 0.9 centimetre, is rotated further the steel plate that causes steel plate central authorities to form a necking down profile along with two rolling wheels; Finally obtain the thick embryo steel plate 12 of two pairs of ventral triangle post external forms.In this process, the external form of rolling wheel 41 and following rolling wheel 42 in the adjustment can be controlled the shape of the thick embryo steel plate 12 after completing.
As mentioned above, the present invention meets patent three important documents fully: the practicality on novelty, creativeness and the industry.With novelty and creative, the invention provides one with heating, rolling, punching press and the step that cuts making the method for blade steel plate, and then reach the purpose that the present invention saves material and makes blade steel plate fast; With regard to the practicality on the industry, the product that utilizes the present invention to derive is when the demand that can fully satisfy existing market.
The present invention discloses with preferred embodiment hereinbefore, so has the knack of this operator and it should be understood that this embodiment only is used to describe the present invention, does not limit the scope of the invention and should not be read as.It should be noted,, all should be made as and be covered by in the category of the present invention such as with the variation and the displacement of this embodiment equivalence.Therefore, protection scope of the present invention is when being as the criterion with the scope that claim was defined.
