[0002] In the angle steel production line, the angle steel is in a positive V shape when it is discharged from the processing host, and needs to be stacked in a reverse V shape when it is stacked and stored. The traditional angle steel production line uses magnetic grippers to flip the angle steel. Each grab requires a reciprocating action. For long angle steels, multiple sets of magnetic grippers are required, resulting in a heavy flipping and grabbing mechanism, slow execution, and low flipping efficiency. In addition, it is difficult to adjust the gripping reference surface of multiple sets of magnetic grippers, which can easily lead to unstable gripping of angle steels and a high failure rate of angle steel flipping.

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment 1

[0023] like Figure 1-4 As shown, the turntable angle steel flipping device includes a flipping motor 3, a flip shaft 2 and an equally divided disc 1. The flip shaft 2 is supported by a plurality of vertical brackets 4, and the flip shaft 2 is rotatably mounted on the top of the vertical bracket 4 in a horizontal direction. The bottom of the vertical bracket 4 is fixedly connected with a horizontal bracket bottom plate, and a ground screw through hole is provided at the edge of the bracket bottom plate. The vertical bracket 4 is fixedly mounted on the ground by passing the ground screw through the ground screw through hole to ensure the support stability of the vertical bracket 4. A bearing seat is fixedly mounted on the top of the vertical bracket 4, and the flip shaft 2 is rotatably connected to the bearing seat, and the bearing seat can reduce the friction when the flip shaft 2 rotates.

[0024] A flip motor 3 is fixedly arranged at the right end of the flip shaft 2, and the rotating shaft of the flip motor 3 is connected to the right end of the flip shaft 2 through a motor reducer 5 and a coupling. A support frame is fixedly installed below the motor reducer 5, and a plurality of equally divided discs 1 are fixedly arranged on the flip shaft 2. The equally divided discs 1 rotate synchronously with the flip shaft 2, and the spacing between each equally divided disc 1 gradually increases from left to right. The spacing between the equally divided discs 1 at the left end is set relatively small to prevent the shorter angle steel from being suspended in the air during flipping. Such an arrangement structure of the equally divided discs 1 can ensure that angle steels of various lengths can be effectively supported to avoid the angle steels being suspended too long. Figure 1 A total of nine equally divided circular disks 1 and five vertical supports 4 are shown, and the five equally divided circular disks 1 on the left have smaller spacing.

[0025] The outer circumference of the equally divided circular disc 1 is evenly distributed with eight notches for grabbing and placing angle steels. The notches for grabbing and placing angle steels are used for grabbing and placing angle steels and then cutting the inverted V-shaped angle steels through the laser angle cutting machine 12. The equally divided circular disc 1 can grab and flip multiple angle steels at the same time. The equally divided circular disc 1 rotates counterclockwise. The upper right end of the notch for grabbing and placing angle steels is integrally formed with a limiting protrusion. The limiting protrusion makes the angle steel more stable when being grabbed. The surface of the equally divided circular disc 1 is evenly distributed along the center of the circle with a number of weight-reducing holes with larger diameters. The weight-reducing holes are used to reduce the weight of the equally divided circular disc 1 itself. The outer side of the weight-reducing holes is evenly distributed along the center of the circle with eight detection holes 8 with smaller diameters. A detection sensor 6 is fixedly provided on the right side of the equally divided circular disk 1 in the middle position. Every time the detection sensor 6 detects that a detection hole 8 passes by, it means that the equally divided circular disk 1 has rotated one-eighth of a circle and needs to pause intermittently. The detection sensor 6 cooperates with the detection hole 8 to realize automatic control of the intermittent circular motion of the equally divided circular disk 1 through the host computer.

[0026] The working process of the above-mentioned turntable angle steel turning device is as follows:

[0027] After the upper computer receives the incoming signal from the angle steel feeding channel 13, it controls the flip motor 3 to start. After the detection sensor 6 scans the detection hole 8, it sends a detection signal to the upper computer, and the upper computer controls the flip motor 3 to pause intermittently; when the upper computer does not receive the incoming signal from the angle steel feeding channel 13, it controls the flip motor 3 not to start. The upper computer controls the flip motor 3 to start, and the flip motor 3 drives the motor reducer 5 to rotate. The motor reducer 5 drives the flip shaft 2 and the equally divided disc 1 to rotate. The angle steel grabbing and placing notches on the equally divided disc 1 can automatically grab the positive V-shaped angle steel on the angle steel feeding channel 13. After the equally divided disc 1 rotates about half a circle, the first angle steel received by the equally divided disc 1 slides onto the transverse conveying device 14 of the angle steel cutting production line. At this time, the sliding angle steel is in an inverted V shape, which automatically completes the flipping of the angle steel from the positive V shape to the inverted V shape, and then the inverted V-shaped angle steel is cut. The equally divided disc 1 is adapted to the angle steel feeding channel 13 of the angle steel cutting production line on the right side. The equally divided disc 1 performs intermittent circular motion, and the upper computer controls the flip motor 3 to rotate one eighth of the circle each time. Embodiment 2

[0030] The transverse conveying device 14 is a prior art, including a conveying bracket, a conveying motor, a transmission shaft, a chain plate conveyor, a proximity switch and a positioning block, etc. The transverse conveying device 14 is used to pause and cut the inverted V-shaped angle steel, and then convey the angle steel to the left outer side of the angle steel cutting production line after cutting, so as to facilitate further conveying the angle steel to the next process. Through the cooperation of the proximity switch and the positioning block, the inverted V-shaped angle steel on the transverse conveying device 14 is paused, and at this time, the laser angle cutting machine 12 moves into position to perform the angle cutting operation. Because it is laser angle cutting, there is no need to apply a clamping force to the angle steel.

[0031] The angle steel feeding channel 13 is a prior art, comprising a channel frame and a rotating wheel installed on the top of the channel frame. The structure of the rotating wheel matches the regular V-shaped angle steel. The regular V-shaped angle steel is conveyed to the appropriate position of the angle steel feeding channel 13 by the pressing and conveying device 10, and is grasped and flipped by the turntable angle steel flipping device 9.

[0032] The material pressing and conveying device 10 is a prior art, and includes a reduction motor, an adjustment cylinder, a material pushing guide rail, and a material pressing base, etc., and is used to convey the incoming angle steel material to the angle steel feeding channel 13 and push it into place.

[0033] like Figure 6-8As shown, the laser angle cutting machine 12 is movably mounted on the three-axis truss 15, and can perform three-dimensional movement of the X-axis, Y-axis and Z-axis on the three-axis truss 15 to cut the angle steel on the transverse conveying device 14.

The upper side of the fixed plate 20 is slidably mounted on the Y-axis bracket 17 through a guide rail, and the Y-axis displacement device 16 is fixedly mounted above the fixed plate 20, and the Y-axis displacement device 16 is used to drive the fixed plate 20 to move horizontally along the Y-axis bracket 17. The Z-axis bracket 22 is slidably installed on the fixed plate 20 through a guide rail, the Z-axis displacement device 21 is fixedly installed on a side of the fixed plate 20, the swing motor 19 is fixedly installed at the lower end of the Z-axis bracket 22, and the laser angle cutting machine 12 is fixedly installed at the end of the swing shaft of the swing motor 19. The swing of the laser angle cutting machine 12 is controlled by the swing motor 19, so that the two surfaces of the end of the angle steel can be cut from two directions respectively, which can reduce cutting slag.
