When the square tube needs to be cut, start the cutting machine 151 and the eleventh cylinder 153. The cutting machine 151 first cuts the raw material square tube into two cross bars, and then cuts them into multiple vertical bars, realizing the automatic cutting of the square tube, which does not require manual operation by the staff, reducing the workload of the staff and improving the cutting efficiency.

[0037] In this embodiment, a feeding component is provided on the top surface of the fixing frame 1. Among them, the feeding component includes a long strip plate 110.

When the sensor reaches the position of the sensor 157, the third motor 113 stops rotating to control the length of the cut square pipe.

[0042] In this embodiment, a first clamping assembly is arranged on the top surface of the fixed frame 1. The first clamping assembly includes a thirteenth cylinder 130. The thirteenth cylinder 130 is horizontally installed on the top surface of the fixed frame 1. A third clamping block 131 is installed on the piston rod of the thirteenth cylinder 130. At the same time, a fourth clamping block 132 corresponding to the third clamping block 131 is installed on the top surface of the fixed frame 1. The thirteenth cylinder 130 is started, and the piston rod of the thirteenth cylinder 130 drives the third clamping block 131 to move. The third clamping block 131 and the fourth clamping block 132 automatically clamp the square pipe to reduce the spontaneous movement of the square pipe when the cutting machine 151 cuts the square pipe.

[0043] A rodless cylinder 150 is horizontally installed on the fixed frame 1. A pushing plate 158 is installed on the piston rod of the rodless cylinder 150. A plurality of guide rods 159 are installed on the top surface of the fixed frame 1.

The rodless cylinder 150 is started, and the rodless cylinder 150 drives the pushing plate 159 to move. A baffle 160 is horizontally installed on the top surface of the fixed frame 1.

[0044] After the cutting machine 151 cuts the square pipe into a cross bar that meets the requirements, the rodless cylinder 150 is started, and the pushing plate 159 pushes the cross bar to move linearly to the position of the baffle 160. The cutting machine 151 continues to cut the square pipe to form a second cross bar.

[0045] In this embodiment, a feeding assembly is arranged on the fixed frame 1. The feeding assembly includes two seventh cylinders 141. The two seventh cylinders 141 are symmetrically installed on the top surface of the fixed frame 1. A moving frame 142 is installed on the piston rods of the two seventh cylinders 141. Two second sliding rods 143 are symmetrically installed on the top surface of the fixed frame 1. Two second sliders 115 are slidably connected to the two second sliding rods 143 respectively. The two second sliders 115 are respectively fixed to the two moving frames 142. The seventh cylinders 141 are started, and the seventh cylinders 141 drive the moving frame 142 to move linearly. The two second sliding rods 143 play a guiding role in the movement of the moving frame 142.

[0046] A cylinder eight 144 is horizontally installed on the top surface of the moving frame 142. The direction of the piston rod of the cylinder eight 144 faces the square tube. A sliding frame 145 is installed on the piston rod of the cylinder eight 144. A cylinder nine 146 is vertically installed on one side of the sliding frame 145. The piston rod of the cylinder nine 146 is set downward. A rotary cylinder 147 is installed on the piston rod of the cylinder nine 146. A cylinder ten 148 is installed on the piston rod of the rotary cylinder 147. The piston rod of the cylinder ten 148 is set downward. An electromagnet two 149 is installed on the piston rod of the cylinder ten 148.

[0047] After the cutting machine 151 finishes cutting two cross bars, it starts to cut the square tube to form a plurality of vertical bars. After one of the vertical bars is cut, the cylinder ten 148 is started. The piston rod of the cylinder ten 148 drives the electromagnet two 149 to move vertically to the top surface of the vertical bar. After the electromagnet two 149 is powered on, it will suck up the vertical bar. The rotary cylinder 147 is started, and the vertical bar changes from the direction perpendicular to the fixture to the direction parallel to the fixture. The cylinder eight 144 is started, and the vertical bar is moved horizontally to a position parallel to the fixture. Then, the cylinder seven 141 is started to move the vertical bar to directly above the fixture. Finally, the cylinder nine 146 is started to convey the vertical bar into the fixture. The above actions are repeated in sequence to realize the automatic conveyance of the cut vertical bars. Without the participation of staff, the conveyance of two cross bars and a plurality of vertical bars can be completed, reducing the workload of the staff and improving the conveyance efficiency.

[0048] In this embodiment, the frame 2 is installed at a preset position. A clamping mechanism is arranged on the top surface of the frame 2.

[0049] Taking one of the driving components three as an example, the driving component three includes two belt pulleys one 2201. The two belt pulleys one 2201 are rotatably connected to the fixed rod 210. The two belt pulleys one 2201 are symmetrically arranged. A motor one 2202 is horizontally installed on the outside of the fixed rod 210. The output shaft of the motor one 2202 passes through the fixed rod 210 and is set inward and fixed to one of the belt pulleys one 2201.

The output shaft of the motor one 2202 drives the belt pulley one 2201 to rotate, and the conveyor belt one 2203 performs a linear motion. The two moving blocks one 250 are both fixed to the conveyor belt one 2203, and the conveyor belt one 2203 drives the two moving blocks one 250 to move linearly at the same time.

[0050] In this embodiment, clamping components are provided on the side of the four moving blocks 250 away from the fixed rod 210. Taking one set of clamping components as an example, the clamping component includes a first cylinder 2301. The first cylinder 2301 is vertically installed inside the moving block 250 through a second fixing block. The piston rod of the first cylinder 2301 is arranged downward. An electromagnet 2303 is installed on the piston rod of the first cylinder 2301. When the first cylinder 2301 is started, the piston rod of the first cylinder 2301 drives the electromagnet 2303 to move vertically.

[0051] Start the two first motors 2202, and the two first conveyor belts 2203 drive the four moving blocks 250 to move to the preset positions in an automated manner. Two of the moving blocks 250 drive the electromagnets 2303 to move into the fixing frame 1 and be directly above the two cross bars. Then start the two first cylinders 2301. The two electromagnets 2303 move vertically to the top surfaces of the two cross bars. After the two electromagnets 2303 are powered on, the two electromagnets 2303 pick up the two cross bars. The two cross bars first move upward, then horizontally, and finally downward to the top surface of the machine frame 2, realizing the automated conveyance of the two cross bars to the top surface of the machine frame 2.

[0052] In this embodiment, a limiting mechanism is provided on the top surface of the machine frame 2. The limiting mechanism has two groups and is symmetrically arranged. The two groups of limiting mechanisms respectively fix the two cross bars. Taking one set of the limiting mechanisms as an example, the limiting component includes a first limiting block 240. The first limiting block 240 is installed on the top surface of the machine frame 2.

The piston rod of the second cylinder 2421 is arranged towards the direction of the second limiting block 241. An L-shaped block 2422 is mounted on the piston rod of the second cylinder 2421. Two chutes are symmetrically formed on the bottom surface of the first mounting block 2420. The L-shaped block 2422 is slidably connected in the two chutes. When the second cylinder 2421 is started, the piston rod of the second cylinder 2421 drives the L-shaped block 2422 to move horizontally. The two chutes play a guiding role in the movement of the L-shaped block 2422. A second strip-shaped hole 24220 is vertically formed on the top surface of the L-shaped block 2422. A third cylinder 2423 is vertically mounted in the second strip-shaped hole 24220. The piston rod of the third cylinder 2423 is arranged downward. A first pressing block 2424 is mounted on the piston rod of the third cylinder 2423. When the third cylinder 2423 is started, the piston rod of the third cylinder 2423 drives the first pressing block 2424 to move vertically. The first pressing block 2424 is slidably connected in the second strip-shaped hole 24220. The second strip-shaped hole 24220 plays a guiding role in the vertical movement of the first pressing block 2424.

[0054] In this embodiment, the first limiting component includes a sixth cylinder 2430 which is horizontally mounted on the top surface of the frame 2 through a third limiting block. A fourth limiting block 2431 is mounted on the piston rod of the sixth cylinder 2430. The fourth limiting block 2431 is arranged opposite to the first limiting block 240. When the sixth cylinder 2430 is started, the piston rod of the sixth cylinder 2430 drives the fourth limiting block 2431 to move linearly.

[0055] After the cross bar is conveyed to the top surface of the frame 2, first, the second cylinder 2421 is started, and the L-shaped block 2422 pushes the cross bar to move linearly into the space between the fourth limiting block 2431 and the first limiting block 240. Then, the sixth cylinder 2430 and the third cylinder 2423 are started simultaneously. The first pressing block 2424 moves to the top surface of the cross bar, and the fourth limiting block 2431 moves to one end of the cross bar. The fourth limiting block 2431 and the first limiting block 240 clamp the two ends of the cross bar, and the first pressing block 2424 fixes the top surface of the cross bar, realizing the automatic fixing of the cross bar on the frame 2 and reducing the spontaneous movement of the cross bar during the processing of the cross bar.

[0056] In this embodiment, a feeding mechanism is arranged on the frame 2. At the same time, a plurality of first strip-shaped holes 20 are horizontally formed on the top surface of the frame 2. The plurality of first strip-shaped holes 20 are arranged along the length direction of the frame 2. A plurality of vertical bars are conveyed between the two cross bars through the plurality of first strip-shaped holes 20.

[0057] Among them, the material feeding mechanism includes a mounting frame 260, which is mounted on the frame 2. Two chains 261 are rotatably connected to the top surface of the mounting frame 260. A plurality of clamps 262 are horizontally mounted on the two chains 261. The plurality of clamps 262 are arranged at equal intervals along the length direction of the two chains 261. A fourth driving component for driving the two chains 261 to move is provided on the mounting frame 260. A plurality of groups of conveying components are symmetrically arranged on both sides of the mounting frame 260.

[0058] In this embodiment, the fourth driving component includes two second rotating shafts 2630, which are rotatably connected to the mounting frame 260 and symmetrically arranged. Two sprockets 2631 are mounted on each of the two second rotating shafts 2630. The two chains 261 are respectively connected in series to two sprockets 2631 opposite to each other in the length direction of the mounting frame 260. One end of one of the second rotating shafts 2630 extends out of the outside of the mounting frame 260, and a second motor 2632 is mounted on the extending end of the second rotating shaft 2630. When the second motor 2632 is started, the output shaft of the second motor 2632 drives the second rotating shaft 2630 to rotate, the second rotating shaft 2630 drives the sprocket 2631 to rotate, and the two chains 261 move. The two chains 261 drive the plurality of clamps 262 to move.

[0059] Taking one group of conveying components as an example, the conveying component includes two support blocks 2640, which are vertically mounted on both sides of the frame 2. Two fourth cylinders 2641 are vertically mounted on the sides of the two support blocks 2640 away from the mounting frame 260. A U-shaped block 2642 is mounted on the piston rods of the two fourth cylinders 2641. When the two fourth cylinders 2641 are started, the two fourth cylinders 2641 drive the U-shaped block 2642 to move vertically.

[0060] After the vertical rod is placed on the clamp 262 in an automated manner, the second motor 2632 is started, and the chain 261 drives the clamp 262 to move to directly above the two U-shaped blocks 2642. At this time, the vertical rod is exactly located directly below the first strip-shaped hole 20. Then, the plurality of fourth cylinders 2641 are started, and the plurality of U-shaped blocks 2642 move vertically to both sides of the vertical rod. The two U-shaped blocks 2642 continue to move to convey the vertical rod upward from the first strip-shaped hole 20 to between the two cross bars. Then, the two cross bars are moved in the same direction so that the inner sides of the two cross bars are in contact with both ends of the plurality of vertical rods.

[0061] In this embodiment, multiple sets of pressing components are provided on the frame 2. After the vertical rod moves to a preset position, the multiple sets of pressing components fix the vertical rod. Taking one set of pressing components as an example, the pressing component includes the second mounting block 270. The second mounting block 270 is horizontally mounted on the top surface of the frame 2. A rotating seat 271 is hinged on the top surface of the second mounting block 270. A second pressing block 272 is hinged on the rotating seat 271. Through holes 1 are vertically mounted on both the frame 2 and the second mounting block 272. A fifth cylinder is vertically mounted on the bottom surface of the frame 2. The piston rod of the fifth cylinder sequentially passes through the two through holes 1 and is hinged to the second pressing block 272. When the fifth cylinder is started, the fifth cylinder drives the second pressing block 272 to rotate, changing the vertically arranged second pressing block 272 to a horizontally arranged one. The second pressing block 272 moves to the top surface of the vertical rod, and the second pressing block 272 fixes the vertical rod, reducing the situation that the vertical rod moves spontaneously during welding.

[0062] In this embodiment, an automatic welding arm 3 is provided on the frame 2. The automatic welding arm 3 is a prior art and will not be elaborated in this application. After the two cross bars and the multiple vertical rods are fixed, the automatic welding arm 3 welds the cross bars and the vertical rods together in an automated manner. The entire welding process is carried out in an automated manner without the need for manual welding by workers, reducing the workload of the workers. After the cross bars and the vertical rods are welded, the clamping mechanism transports the welded guard bars from the frame to the position for placing the guard bars in an automated manner.
