Technical field
The present invention relates to field of machining, particularly a kind of method of making U-shaped metallic plate.
Background technology
Often need to make U-shaped metallic plate in field of machining, prior art utilizes pressing equipment and process for stamping to make U-shaped metallic plate conventionally.
For example, the Chinese patent application that application number is 201010507337.3 discloses alternative techniques and the mould of a kind of crescent U-shaped steel plate blanking part blanking process and blanking die, belongs to the metal cool-press technical field in machine industry.The technical essential of its technical scheme is: steel plate is cut into the vertical bar material of needed length and width with plate shearing machine, and the length direction of vertical bar material is parallel with the rolling direction in Plate Production.By tens of neat overlaping of vertical bar steel plate, the width of vertical bar steel plate is in the bending die that is placed on bending mould perpendicular to horizontal plane, pressure die in bending patrix automatically along two sides of the vertical bar steel plate overlaping by whole vertical bar steel plate overall clampings, bending punch carries out bending to the vertical bar steel plate clamping, and obtains the geometry identical with the blanking part of blanking process and the part of size.
In the situation that some output is less, need the method for easier making U-shaped metallic plate.
Summary of the invention
In view of this, the present invention proposes a kind of method of making U-shaped metallic plate, in order to make more easily U-shaped metallic plate.
According to an embodiment of the present, provide a kind of method of making U-shaped metallic plate, having comprised:
Bending one metallic plate;
After bending, a cushion block is placed in the inner side of metallic plate, and flattens metallic plate after this bending.
Preferably, to make the angle between metallic plate biside plate be acute angle in described bending.
More preferably, described acute angle is less than or equal to 45 °, is preferably 30 °.
According to a kind of embodiment, the cushion block that described cushion block is integrated.
According to another kind of embodiment, described cushion block comprises stacked a plurality of subpad pieces.
Alternatively, utilize a bender to carry out bending.
Alternatively, utilize a bender to flatten.
From such scheme, can find out, due to technical scheme of the present invention, make U-shaped metallic plate by the shirtsleeve operation such as bending and pressing, so have easy feature, make efficiency is higher.And this technical scheme does not have the restriction such as staking punch and tonnage of stamping technology, so can being applicable to the workpiece of different materials and thickness, this technical scheme makes.This technical scheme can realize with common bender, does not need special pressing equipment, therefore can save the expense of pressing equipment and diel.

The plate of the thickness of slab h U-shaped metallic plate of a U-shaped metallic plate inner surface interval d U-shaped metallic plate is wide
The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, the present invention is described in more detail by the following examples.
Fig. 1 is the sectional view that relates to workpiece in the present embodiment.This workpiece is a U-shaped metallic plate, and described U-shaped is the feature of the required processing of the present embodiment method.As shown in Figure 1, the thickness of slab d of U-shaped metallic plate 101 is 0.5mm, and the wide h of plate is 12mm, and between the inner surface of U-shaped metallic plate both sides, interval a is 2mm.The upper deviation 0.1mm of described interval a, lower deviation is 0, the size of interval a need to be controlled at 2.0mm between 2.1mm.U-shaped metallic plate 101 also comprises other parts, for example through hole 1011.Because the emphasis of the present embodiment does not lie in the other parts 1011 of processing work, therefore the present embodiment is not done more detailed introduction to these parts 1011.
In the time making U-shaped metallic plate 101, conventional method is to use the once punch forming on punch press of stamped female convex mold, and this process for stamping adds man-hour for the U-shaped metallic plate 101 of different-thickness, needs different moulds.
In the present embodiment, adopt conventional mould, for example Bending Mould and pressing die are processed U-shaped metallic plate 101 on common bending machine.
According to the present embodiment, concrete processing method comprises the following steps:
Step S11, bending metallic plate.
Fig. 2 is the schematic diagram that adopts bender bending metallic plate 201.This step can be divided into again following two step by step:
Step S111, selects bending point.
In the present embodiment, need U-shaped metallic plate 101 left and right sides metallic plate width h of processing consistent, so bending point selection is at metallic plate mid point.But it will be appreciated by those skilled in the art that the inconsistent situation of two side plates, 2021 and 2022 width for U-shaped metallic plate, bending point should be made corresponding change.
Step S112, selects bending angle.
In order to facilitate follow-up pressing step, the selection at bending angle makes two angles between side plate the smaller the better.In the present embodiment, selected the 201 pairs of metallic plates 202 of fixing a cutting tool of 30 ° to carry out bending.In fact, can be on the basis of the upper and lower cutter 201 and 203 of existing bender, flatten as principle to facilitate, select to have fixing a cutting tool of less nose angle and 201 carry out bending.
So far can obtain a metallic plate 202 that has certain angle of bend, and two side plates 2021 and 2022 of metallic plate 202 preferably shape is in an acute angle.This metallic plate 202 also comprises a bent angle 2023.
Step S12, flattens metallic plate.
As shown in Figure 3, between two side plates of above-mentioned crooked metal sheet 202, (inner side of metallic plate after being bending) placed a thickness and equaled the cushion block 302 of U-shaped metallic plate 101 metallic interior surface interval, both sides a.Cushion block 302 can be the cushion block of an one, can be also the cushion block that comprises a plurality of stacked subpad pieces.
Then inner side is placed with after the bending of cushion block 302 to metallic plate 202 and is placed in and flattens on bed die 303, utilize to flatten mold 301 and flatten.
The application relates to Machining Technology field, discloses a kind of method of making U-shaped metallic plate, comprising: bending one metallic plate; After bending, a cushion block is placed in the inner side of metallic plate, and flattens metallic plate after this bending.Due to technical scheme of the present invention, make U-shaped metallic plate by the shirtsleeve operation such as bending and pressing, so have easy feature, make efficiency is higher.And this technical scheme does not have the restriction such as staking punch and tonnage of stamping technology, so can being applicable to the workpiece of different materials and thickness, this technical scheme makes.This technical scheme can realize with common bender, does not need special pressing equipment, therefore can save the expense of pressing equipment and diel.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
