Description
Technical Field
The utility model relates to the technical field of bending equipment, in particular to a manual flat steel bending device.
Background
Chinese patent CN108655226a discloses a multifunctional flat steel horizontal bending machine, comprising an end shaft driven by a hydraulic jack, and two limit leveling rollers. Firstly, the flat steel is abutted against the limiting leveling rollers, then the end shafts press the flat steel between the limiting leveling rollers, and finally the driving device drives the limiting leveling rollers to rotate, so that bending of the flat steel is completed.
Because the position of the limit leveling roller is fixed, when the flat steel is thicker and the bending radian is larger, the extending amplitude of the end shaft is smaller, the bending amplitude of the flat steel is also smaller, the resilience force of the flat steel is difficult to overcome, and the flat steel is subjected to normal deformation. After the bending process is completed, the flat steel is easy to reset to a flat state. Therefore, how to overcome the above-mentioned drawbacks is a problem to be solved by the person skilled in the art.

Firstly, placing flat steel at the upper end of a carrier roller, then driving a pressing rod to descend by a driving assembly, pressing the flat steel to bend the flat steel to a certain extent, and finally driving the pressing rod to rotate by the driving assembly, wherein the pressing rod drives the flat steel to move along the arc direction to bend and form the flat steel. The radian of the flat steel can be adjusted by adjusting the height of the compression bar; the bending amplitude of the flat steel can be adjusted by adjusting the distance between the carrier rollers; when the flat steel is thicker and the bending radian is larger, the distance between the carrier rollers is increased, the pressing-down amplitude of the pressing rod can be increased, and the bending amplitude of the flat steel is improved, so that the flat steel is convenient to bend and form.
The specific structure of the carrier roller and the bracket joint is as follows: two groove plates which are arranged in parallel are arranged on the support, a plurality of clamping grooves are formed in the groove plates, and two ends of the carrier roller are clamped in the clamping grooves.
The carrier rollers are generally positioned at the same horizontal position, and the radian of the bent flat steel is distributed regularly; however, in a special working condition, the flat steel is required to have an irregular bending radian, and the structure cannot be realized, so that the problem is further improved and solved, and particularly, the groove plate is provided with two groove groups which are symmetrically arranged, and each groove group comprises a plurality of clamping grooves; the height of the clamping groove on each groove group is gradually decreased from outside to inside. Therefore, the position of the carrier roller is adjusted to ensure that the carrier roller has a height difference, and flat steel with irregular radian can be processed. According to the arrangement, not only can the horizontal distance of the carrier roller be adjusted, but also the height difference of the carrier roller can be adjusted, so that the flat steel with regular radian can be processed, the flat steel with irregular radian can also be processed, and the practicality is higher.
The specific structure of the lifting component is as follows: the lifting assembly comprises a lifting seat, and a screw rod which is vertically arranged is connected on the lifting seat in a threaded manner; one end of the compression bar is arranged on the lifting block, and a spring is connected between the lifting block and the bracket; the lower end of the screw rod is propped against the lifting block. The screw rod is used for driving the lifting block to descend, and the restoring force of the spring is used for driving the lifting block to ascend.
Traditional depression bar goes up and down unstably, based on this, further design is: two guide rods which are symmetrically and vertically arranged are arranged on the bracket; the two sides of the lifting block are sleeved on the guide rod.
To drive the plunger to rise steadily, the expansion and contraction of the spring must be stable, based on which the following is further improved: the spring is also sleeved on the guide rod.
The driving block is easy to fall off from the guide rod due to overlarge lifting amplitude, so that the problem is further improved and solved, and particularly, the upper end of the guide rod is sleeved with a limiting ring and fixed through a pin shaft. Thus, the limiting ring plays a role in blocking the driving block.
The specific structure of the driving component is as follows: the lifting block is provided with a bearing, and the rear end of the compression bar penetrates through the bearing and is fixedly connected with the rocking handle; the rocking handle is set as the driving component.
Because the friction between the flat steel and the carrier roller and the compression bar is small, the compression bar is easy to slip when rotating, and the flat steel is unstable to move, the problem is further improved and solved, and particularly, the front ends of the carrier roller and the compression bar are coated with rubber layers on the peripheral walls of the carrier roller and the compression bar. The friction coefficient of the rubber layer is large, so that the friction force between the flat steel and the carrier roller and the compression bar can be increased.
