The bending device is described below with reference to fig. 1 and 3.
As shown in fig. 1, a bending device according to the present invention comprises:
a work station 1100. Two bending mechanisms 1200 are symmetrically arranged, and each bending mechanism 1200 comprises a trapezoidal positioning block 1210, a rotating strip 1220, a bending strip 1230 and a positioning piece 1250. The positioning member 1250 includes a first rotating shaft 1252 and a base 1251, and a lower end of the first rotating shaft 1252 is connected to the base 1251. One end of the rotary bar 1220 is rotatably connected to the first rotary shaft 1252. A workpiece placing space 1240 is formed by one side of the trapezoid positioning block 1210 and one side of the base 1251. The upper end of the bending bar 1230 is connected to the rotating bar 1220, and the lower end of the bending bar 1230 is on the same level with the workpiece placing space 1240.
Two driving components 1400, the driving components 1400 correspond to the bending mechanisms 1200 one by one, and the driving components 1400 are used for driving the rotating bars 1220 to rotate around the first rotating shaft 1252.
It is to be understood that two points may be defined between one, and since the bending mechanism 1200 is symmetrically disposed, two work placing spaces 1240 are formed on the table 1100. When the workpiece is placed therein, both ends of the workpiece are clamped by the workpiece placing space 1240.
It should be appreciated that the sides of the base 1251 adjacent to the trapezoidal positioning block 1210 are parallel to each other.
It should be understood that the lower end portion of the press bending bar 1230 is on the same level with the workpiece placing space 1240. Accordingly, the bending bar 1230 may provide a bending force at a side of the workpiece to be bent during the rotation to bend the workpiece.
Accordingly, a workpiece is placed in the workpiece placing space 1240, and the rotating bar 1220 is driven by the driving part 1400 to rotate along the first rotating shaft 1252, so that the bending bar 1230 simultaneously rotates about the first rotating shaft 1252, and during the rotation, the lower end portion of the bending bar 1230 is always in contact with the workpiece, so that the workpiece is bent in the rotating direction of the bending bar 1230. When the workpiece is bent to a certain angle, the driving part 1400 stops driving and returns to its original position, and at this time, the workpiece is bent at the angle. Because the bending mechanisms 1200 are symmetrically arranged, the workpieces can form two symmetrical included angles at the same time, and therefore the production efficiency is improved.
In some embodiments, the bending apparatus further includes a strip-shaped concave hole 1221 disposed on the rotating strip 1220, and one end of the bending strip 1230 is clamped on the rotating strip 1220 through the strip-shaped concave hole 1221.

The rotary bar 1220 is provided with a strip-shaped groove 1222, and the second rotating shaft 1431 passes through the strip-shaped groove 1222 to be connected with the upper and lower ends of the clamping block 1430, so that the second rotating shaft 1431 and the first rotating shaft 1252 are far away from or close to each other during the rotation of the rotary bar 1220. The clamping block 1430 is pushed to move by the air cylinder 1420, so that the second rotating shaft 1431 provides a pushing force to the rotating bar 1230 to rotate it horizontally. Meanwhile, since the rotating rod 1230 is rigid, the air cylinder 1420 can only move along a straight line, and therefore, the design of the strip-shaped groove 1222 enables the second rotating shaft 1431 to be close to the first rotating shaft 1252 when the rotating rod 1230 is bent, so as to avoid the rotating rod 1230 from being broken, and thus the air cylinder 1420 can push the rotating rod 1230 to rotate.

The limit lever 1462 is parallel to the piston 1421. Through the mutual matching of the limiting rod 1462, the first nut 1461, the first connecting plate 1440 and the second baffle 1450, the pushing-out length of the piston 1421 can be fixed, so that the accuracy of the bending angle is improved.

The driving part 1400 may be fixed by the driving part placing platform.
It should be understood that, since one end of the driving member platform is connected to the working platform 1100 and the other end of the driving member platform is suspended, the two ends of the working platform 1100 are not uniformly stressed, and therefore, as shown in fig. 2, the lower end of the working platform 1100 extends and protrudes towards the other end of the first plate 1610, which can provide a supporting force for the driving member platform, thereby making the working platform 1100 more stable.
