In steps A, at first make the first fixed head 21, the second fixed head 22 and backing plate 4, for the installation of flitch 3 ready.In step B, flitch 3 is installed on the backing plate 4, flitch 3 is installed in the gap that has between the first fixed head 21 and the second fixed head 22 simultaneously, the end that flitch 3 is positioned at the gap is flanging 31, the end of described flanging 31 contacts with the first fixed head 21, the other end of flanging 1 contacts with the second fixed head 22, and forms angle α with backing plate 4.The height that the length L 1 that flanging 31 has has less than or equal to the second fixed head 22; Thereby the flanging 31 that has guaranteed flitch 3 can be by abundant bending, flanging 31 can bending to the position vertical with flitch 3.If the length L 1 of flanging 31 is greater than the height of the second fixed head 22, flanging 31 can't be by bending to the position vertical with flitch 3.Therefore be that flitch 3 is sent into veneer reeling machine 1 and suppressed ready by step B.At first flitch 3 and backing plate 4 are installed on the veneer reeling machine 1 in step C neutralization procedure D, then suppress by 1 pair of flitch of veneer reeling machine, so that the flanging 31 of flitch 3 is by bending, bending angle is α.In step e, readjust by the position in the gap of the first fixed head 21 and the second fixed head 22 of 3 flangings 31 of flitch after the bending, so that flanging 31 is vertically placed.Place simultaneously seben 5, so that the first fixed head 21 and the second fixed head 22 clamp flanging 31 and seben 5.In step F, will adjust position flitch 3 and backing plate 4 reinstalls on the veneer reeling machine 1.In step G, mounted flitch 3 is again carried out the compacting second time so that flanging 31 by bending to the position vertical with flitch 3.An end of in the H step flitch 3 not being suppressed is installed in the gap between the first fixed head 21 and the second fixed head 22 and carries out bending, and repeating step B obtains compressing flitch 3 to G.In step H, as shown in Figure 5, if after flitch 3 installations are fixed, the upper surface 61 of flitch 3 makes progress, and the steel ladder that then suppresses is marked time and is " N " font; As shown in Figure 6, if after flitch 3 installations were fixed, the steel ladder that the lower surface of flitch 3 upwards then suppresses was marked time and is " Z " font.As shown in Figure 1, when the upper surface 61 of flitch 3 referred to be installed in flitch 3 on the backing plate 4 in step B, the face that makes progress on the flitch 3 was the upper surface 61 of flitch 3, and downward face is lower surface 62.
Adopt the method for above-mentioned veneer reeling machine pressed-steel ladder rung, can avoid adopting flower to cut bending method, owing to only taking the part cutting, cause cutting part to bend rear right angle without circular arc, Integral bending sample preparation formula disunity, the shortcoming that quality technique is relatively poor.Also can avoid adopting the steel plate Combination Welding, after the moulding the whole right angle of marking time all without circular arc, the shortcoming that corner angle are many; Can also avoid simultaneously adopting the method for lever knuckle or jack compacting, though all steel ladder is marked time and can be reached the steel plate quality technological requirement of marking time, it drops into, and manpower is many, labour intensity is also large, causes the inefficient shortcoming of production work.Adopt the method to suppress bending by 1 pair of flitch 3 of veneer reeling machine, thereby can reduce artificial input owing to adopting machine that flitch 3 is carried out bending, increase work efficiency, be fixed by the first fixed head 21 and the second fixed head 22 on backing plate 4 owing to flitch 3 simultaneously, flanging 31 is measure-alike at every turn, therefore also can guarantee the flitch 3 compressing rear quality technological requirements that steel ladder is marked time that satisfy, can guarantee that flitch 3 Integral bending sample preparation formulas are identical.
For so that the first fixed head 21 and the second fixed head are made simply, reduce cost of manufacture.The first fixed head 21 and the second fixed head 22 can have multiple choices, channel-section steel, iron block etc.Wherein a kind of optimal way is that the first fixed head 21 described in the steps A and the second fixed head 22 have identical fixed head height h, and all adopts channel-section steel.The first fixed head 21 adopts channel-section steel and has identical fixed head height h with the second fixed head 22, can carry out blanking at same channel-section steel in the process of making.Can reduce the waste of channel-section steel.Simultaneously so that make the first fixed head 21 and the second fixed head 22 is simple and easy, channel-section steel easily obtains simultaneously, and cost is lower, and is just damaged to being difficult for more greatly, and long service life has guaranteed the repeatedly compacting precision of flitch 3 to have lowered cost of manufacture.
In order to adjust the length of flanging 31, simultaneously so that flitch 3 in the process of compacting, be difficult for from the gap, skidding off.The end of the flanging 31 described in the step B arranges groove 23 with the position that the first fixed head 21 contacts; Among the step C with the end of the flanging 31 of flitch 3 with insert groove 23; The end of the other end of among the step H flitch 3 being suppressed inserts groove 23.As shown in Figure 7, the spacing in gap is a, and the distance of groove 23 distances the first fixed head 21 upper surfaces is b, and the length L 1 of flanging 31 consists of a right angled triangle with a and b, Therefore the spacing a that regulates between the first fixed head 21 and the second fixed head 22 just can adjust flanging length L 1.Groove 23 is set simultaneously, and the end of the flanging 31 of flitch 3 inserts groove 23 in step C, and flitch 3 inserts groove 23 for the end of compacting one end among the step H.Thereby the length that has guaranteed each flanging 31 is consistent, has guaranteed compacting quality technique.
Flitch 3 is being installed to rear on the backing plate 4 and backing plate 4 formation angle α, and angle α is acute angle.Wherein a kind of optimal way is the angle α described in the step C, and α is 45 °.The angle α of flitch 3 and backing plate 4 has determined the bending angle of for the first time flitch 3 being carried out bending.The bending angle equates with the angle α of backing plate 4 with flitch 3.Because it is vertical with flitch 3 main bodys that final flitch 3 is bent into behind the type flanging 31 of flitch 3.Therefore when α was 45 °, flanging 31 for the first time bending angles were 45 °, carry out suppressing the second time bending angle and also are 45 °.Therefore guaranteed that the bending angle of twice compacting is identical, thereby be conducive to simplify the operation, be conducive to control operation.
For so that flitch 3 laterally can fully by bending, can not cause fold in the process flitch 3 of once suppressing.Has identical fixed head length L 2 at the first fixed head 21 described in the step C and the second fixed head 22, flitch length L 3≤fixed head length L 2 that described flitch 3 has.Because therefore flitch length L 3≤fixed head length L 2 can guarantee that flanging 3 integral body of flitch 3 are between the gap of the first fixed head 21 and the second fixed head 22.Under the supporting role of the second fixed head 22, flitch 3 transverse integral are by bending.Thereby can guarantee along its length disposable bending of flitch 3.
Flitch 3 can be the steel plate of various ways, the steel plate that common plane is smooth, checkered steel plate etc., and wherein a kind of optimal way is that flitch 3 adopts checkered steel plate.Because checkered steel plate has the protruding pattern pattern in its surface, so the surface of steel plate out-of-flatness, will form larger frictional force during with object contact, use can be played anti-skidding effect as steel ladder pedal.
Backing plate 4 can be various ways, plank, steel plate etc.Wherein a kind of optimal way is that backing plate 4 adopts steel plate, because armor plate strength is larger, steel plate is high temperature resistant.Therefore backing plate 4 adopts steel plate, can guarantee that the life cycle of backing plate 4 is longer, and service life is longer.
