Abstract
The invention discloses a method for rolling pre-bend flat plates. The method is characterized by comprising steps of 1, pre-bending two ends of a flat plate on a bending machine so that the requirement on the radian of a product can be met after each end of the flat plate is continuously bent in a certain quantity of pre-bending processes; 2, placing the flat plate with the pre-bent ends into a three-roller rolling machine to roll the flat plate so as to obtain the product with the required radian. The method has the advantages that two end scraps generated when ends of an existing flat plate are removed can be prevented by the process of the method, accordingly, raw materials can be saved, and the machining cost can be greatly reduced.
Description
Technical field
the present invention relates to a kind of dull and stereotyped processing method, the dull and stereotyped volume of especially a kind of pre-bending circle method.
Background technology
at present, due to the version of three roller furling plate round machine itself, cause two terminations of radian shape product of being processed into there is no radian, processing operator will expect needed radian product, two must be removed without radian termination, also just say after volume circle and will have the operation of one removal without radian termination.Both caused and lost time, wasted again material.
Summary of the invention
the present invention seeks to: provide a kind of and can directly obtain required radian product, the dull and stereotyped volume of the pre-bending circle method of the material that avoids waste.
technical scheme of the present invention is: the dull and stereotyped volume of a kind of pre-bending circle method, it is characterized in that, and comprise the following steps:
(1) two terminations of flat board are pre-bended on bender, each termination pre-bends, and several makes these continuous bendings form needed product radian;
(2) two ends have been completed to the flat board pre-bending and put into three roller furling plate round machine and roll up circle, obtained the product of required radian.
further, the pre-bend length of termination of two of described flat board needs is not less than the half of two lower roller shaft distances of three roller furling plate round machine.
further, the road number that described termination pre-bends is 8-10 road
advantage of the present invention is:
process of the present invention need to solve the existing waste of material problem of existing method, two that while solving because of three roller furling plate round machine roll bendings, produce without radian termination problem, be exactly before volume circle, pre-bending is carried out in two terminations of flat board on bender, the pre-bend in each termination is counted 8-10 road, these continuous bendings form needed product radian, after volume circle, directly obtain needed radian product, have stopped two termination waste materials that produce because removing termination.Save raw material, greatly reduced the cost of processing.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the invention will be further described:
fig. 1 is existing processing method schematic diagram.
fig. 2 is processing method schematic diagram of the present invention.
wherein: 1 straight line termination; 2 volume round plates; 3 furling plate round machine lower rolls; 4 furling plate round machine lower rolls; 5 pre-fold bent-up end.
The specific embodiment
embodiment: existing process volume circle as shown in Figure 1, after having justified, volume obtains containing two d length straight line terminations 1, after these two d length terminations 1 must be removed, be only needed radian product.Processing method of the present invention as shown in Figure 2, before volume circle, pre-bending is carried out in two terminations of flat board on bender, bending minimum length is not less than the half of the distance x between furling plate round machine lower roll 3 and furling plate round machine lower roll 4, the pre-bend in each termination is counted 8-10 road, these continuous bendings form needed product radian and obtain pre-folding bent-up end 5, then two ends have been completed the volume round plate 2 pre-bending put into three roller furling plate round machine roll up circle, obtain the product of required radian, stopped two waste of material that termination waste material causes that produce because removing termination.Technique of the present invention is simple, easy to use, has saved production technology, has avoided the waste of material, for enterprise provides cost savings.
the above, the only specific embodiment for inventing.Protection scope of the present invention is not limited to this, any be familiar with those skilled in the art the present invention disclose technical scope in, the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
Claims (3)
1. the dull and stereotyped volume of a pre-bending circle method, is characterized in that, comprises the following steps:
(1) two terminations of flat board are pre-bended on bender, each termination pre-bends, and several makes these continuous bendings form needed product radian;
(2) two ends have been completed to the flat board pre-bending and put into three roller furling plate round machine and roll up circle, obtained the product of required radian.
2. the dull and stereotyped volume of pre-bending according to claim 1 circle method, is characterized in that, the pre-bend length of termination of two needs of described flat board is not less than the half of two lower roller shaft distances of three roller furling plate round machine.
3. the dull and stereotyped volume of pre-bending according to claim 1 circle method, is characterized in that, the road number that described termination pre-bends is 8-10 road.
