Before people use the thin steel plate to process into other products, when the thin steel plate needs to be bent, the equipment can be used, firstly, the pedal 7 is stepped downwards to drive the hollow frame 4 to move downwards, the pedal 7 moves downwards to drive the first slide bar 10 to move downwards in the slotted hole 13, the second spring 12 is compressed, the first slide bar 10 moves downwards to drive the baffle 11 to move downwards, the baffle 11 pulls the two sliding clamping blocks 17 to move towards the inner side of the second sliding hole 16 through the pull rope 15, the third spring 18 is compressed, the sliding clamping blocks 17 are separated from the first clamping groove 19, the sliding clamping blocks 17 do not clamp the guide rod 3, the hollow frame 4 drives the guide rod 3 to move downwards, the first spring 9 is stretched, so that the support plate 20 moves downwards, the support plate 20 moves downwards to drive the first roller 21 to move downwards, the hollow frame 4 is stopped to move, the thin steel plate is placed above the first roller 21, and then the end of the thin steel plate needing to be bent is placed below the second roller 261, when the pedal 7 is released, the first spring 9 is reset to move the guide rod 3 upwards, the support plate 20 also moves upwards, when the first slide bar 10 moves upwards under the action of the reset of the second spring 12, when the sliding block 17 on the guide rod 3 moves to the position of the first clamping groove 19, the two sliding blocks 17 move outwards under the action of the reset of the third spring 18, the sliding block 17 is matched with the first clamping groove 19 to clamp the guide rod 3, the support plate 20 stops moving upwards to enable the thin steel plate to be contacted with the limit plate 221, at this time, one can pull the handle 25 downwards to drive the second roller 261 on the arc-shaped rod 26 to press the thin steel plate downwards to bend the thin steel plate, the expansion device 27 below the thin steel plate can limit the bending amplitude of the thin steel plate, the limit plate 221 can prevent the left end of the thin steel plate from moving upwards in the bending process to influence the bending of the thin steel plate, when the bending of the thin, the pedal 7 is then stepped down to move the guide rod 3 downward, so that the bent thin steel plate on the support plate 20 is away from the limit plate 221, and the bent thin steel plate is taken out to release the pedal 7.
When the thin steel plate presses the third roller 274 downwards, the third roller 274 drives the second sliding bar 273 to move downwards in the first sliding pipe 271, the fourth spring 272 is compressed, the third roller 274 limits the bending amplitude of the thin steel plate, when the thin steel plate is taken out, the thin steel plate does not press the third roller 274 downwards any more, the second sliding bar 273 moves upwards to the original position under the action of the reset of the fourth spring 272, and the third roller 274 is driven to move upwards to return to the original position.
Firstly, the thin steel plate is pushed to the upper part of the first roller 21, the third arc slide bar 30 penetrates into the first arc slide sleeve 29, the right end of the third arc slide bar 30 extends into the groove block 28, the first screw 34 is rotated, the first screw 34 is inserted into the clamping hole 32, the third arc slide bar 30 is fixed, when the pulling handle 25 moves downwards, the arc rod 26 swings towards the right and downwards to drive the groove block 28 to swing towards the right, the groove block 28 drives the third arc slide bar 30 to swing upwards through the first screw 34, the third arc slide bar 30 swings upwards to drive the fourth roller 31 to move upwards, the fourth roller 31 moves upwards to contact with the thin steel plate to bend the thin steel plate, the thin steel plate is bent to contact with the fifth roller 38, the fourth slide bar 37 moves upwards, the fifth spring 36 is compressed to limit the bending amplitude of the thin steel plate, when the thin steel plate is taken away, the thin steel plate does not apply an upward force to the fifth roller 38 any more, the fourth sliding rod 37 is reset by the action of the fifth spring 36, when the third arc-shaped sliding rod 30 is not needed to be used, the first screw 34 is rotated to make the first screw 34 leave the clamping hole 32, and the third arc-shaped sliding rod 30 is taken out from the first arc-shaped sliding sleeve 29 and the groove block 28, so that the left thin steel plate can be bent while the right side is bent, and the working efficiency is increased.
When the thin steel plate is bent to be pressed against the fifth roller 38 to a proper position, the second screw 41 is rotated to make the second screw 41 and the corresponding second catching groove 39 cooperate, so that the left side of the thin steel plate is prevented from being bent to an excessive extent during the bending, and when the thin steel plate is pressed against the third roller 274 to a proper position, the third screw 44 is rotated to make the third screw 44 and the corresponding third catching groove 42 cooperate, so that the right side of the thin steel plate is prevented from being bent to an excessive extent during the bending.
When the handle 25 is pulled downwards to bend the thin steel plate, the handle 25 drives the fifth arc-shaped sliding rod 49 to move downwards, so that the fourth clamping groove 50 on the right side of the fifth arc-shaped sliding rod 49 moves downwards to be matched with the shifting clamping rod 47, and the fourth clamping groove 50 is matched with the shifting clamping rod 47 to fix the handle 25. When the bending time of the thin steel plate reaches a certain degree, the toggle clamping rod 47 is pulled downwards, the sixth spring 48 is stretched, the toggle clamping rod 47 does not clamp the fourth clamping groove 50 any more, the handle 25 moves upwards, the thin steel plate can be bent and shaped, the condition that the handle 25 is pulled by an operator for a long time is avoided, and therefore the working strength of the operator can be reduced.
