DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Combination Figures 1 to 5 The present embodiment is described. The present embodiment provides a steel plate bending equipment, which includes a workbench 1. A bracket 2 is fixedly connected to the bottom of the workbench 1. Two symmetrical strips 3 are fixed to the top surface of the workbench 1. One end of the strip 3 is a steel plate feeding end, and the other end is a steel plate discharging end. The steel plate is laid on the top surface of the strip 3 and moves along the length direction of the strip 3. A bending mechanism 4 is provided between the steel plate feeding end and the steel plate discharging end of the strip 3. The bending mechanism 4 is divided into two groups and both are located on the outside of the strip 3. The bending mechanism 4 includes a plurality of pressure balls 41. The pressure balls 41 are arranged along the length direction of the strip 3, and the lowest point of the pressure balls 41 at the steel plate feeding end is higher than the top surface of the strip 3, and the distribution of the pressure balls 41 gradually decreases in height from the steel plate feeding end to the steel plate discharging end. A limiting mechanism 5 is also provided on the outside of the steel plate. The limiting mechanism 5 is divided into two groups, one group is distributed on the outside of the strip 3 at the steel plate feeding end, and the other group is distributed on the outside of the strip 3 at the steel plate discharging end.

[0017] In this embodiment, if Figure 1 , Figure 4As shown, the bending mechanism 4 includes a crossbeam 42, which is fixedly connected to the workbench 1 through a supporting rod, and the bottom surface of the crossbeam 42 includes an arcuate surface 421 and a horizontal surface 422. The pressure ball 41 is movably installed on the arcuate surface 421 and the horizontal surface 422 on one side close to the strip plate 3, and the distribution of the pressure ball 41 on the arcuate surface 421 is an arcuate trajectory, and the distribution of the pressure ball 41 on the horizontal surface 422 is a straight trajectory. The pressure balls 41 distributed on the arcuate surface 421 gradually press down the edge of the steel plate until the edge of the steel plate is finally bent downward, and the pressure balls 41 on the horizontal surface 422 keep the steel plate in a bent state. In the process of moving the steel plate, the contact point of the steel plate to be bent with the steel ball gradually changes, and the changing path of the contact point is a curve. The cross beam 42 is provided with an insertion groove, into which the pressure ball 41 is placed, and the pressure ball 41 can rotate in any direction in the insertion groove, thereby reducing the friction between the pressure ball 41 and the steel plate and reducing the damage to the steel plate. The pressure ball 41 is a steel ball. The shortest distance between the pressure ball 41 and the side of the strip plate 3 is consistent with the thickness of the steel plate. After the steel plate moves to the rear pressure ball 41, the pressure ball 41 squeezes the bending edge of the steel plate, so that the steel plate forms a 90° bend. Of course, the shortest distance between the steel plate and the pressure ball 41 can be adjusted according to demand.

[0018] A plurality of drive rollers 43 are axially connected between the crossbeams 42 of the two bending mechanisms 4. The drive rollers 43 are arranged along the length direction of the strip 3. A gear 44 is fixedly connected to the shaft at one end of the drive roller 43. The gears 44 are connected by a toothed belt 45. A drive motor 48 is connected to the shaft of one of the drive rollers 43. The drive motor 48 is used to drive the drive roller 43 to rotate. The gear 44 and the toothed belt 45 structure drive all the drive rollers 43 to rotate. The drive roller 43 drives the steel plate to move, and a pressure strip 46 is provided above the strip 3. The pressure strip 46 is fixedly connected to the crossbeam 42 by a connecting rod 47. The pressure strip 46 is used to press down the steel plate to prevent the steel plate from bending and deformation when bending.

[0019] A plurality of rollers 6 are movably connected between the two strips 3. The highest point of the rollers 6 is flush with the top surface of the strips 3. The rollers 6 support the middle of the steel plate and cooperate with the driving rollers 43 to drive the steel plate to move.

[0020] like Figure 1 As shown, the limiting mechanism 5 includes a coaxially arranged column 51 and a limiting roller 52, the column 51 is fixedly connected to the workbench 1, the limiting roller 52 is movably connected to the column 51, the distance between the limiting rollers 52 on both sides of the steel plate feeding end of the strip 3 is the same as the width of the steel plate, and the distance between the limiting rollers 52 on both sides of the steel plate discharging end of the strip 3 is the same as the width of the steel plate after bending, and the width directions of the steel plate before and after bending are limited respectively, and multiple limiting mechanisms 5 on each side are evenly spaced.

[0021] The working principle of the present invention is: the steel plate is placed into the steel plate feeding end of the strip plate 3, the driving motor 48 drives the driving roller 43 to rotate and drives the steel plate to move forward, and in the process of the steel plate moving, the pressure ball 41 gradually presses the edge of the steel plate downward, and the strip plate 3 supports the bending point of the steel plate until the edge of the steel plate is bent. The bent steel plate is discharged from the steel plate discharging end of the strip plate 3, realizing the assembly line bending operation of the steel plate, greatly improving the bending efficiency of the steel plate, and reducing the work intensity of the workers.
