DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] Combination Figure 1 and Figure 2 As shown, a high-speed pneumatic small copper bar bending device comprises a workbench 1, a bending seat arranged at the front end of the workbench 1, and a top block 3 connected to the workbench 1 by a cylinder 2 that can be telescoped forward and backward;

[0023] The rear end of the bending seat has a bending groove 4 corresponding to the copper busbar 14, and the workbench 1 is also provided with a blanking groove 5, and the blanking groove 5 is arranged close to the edge of the bending groove 4;

[0024] It should be noted that the inverted U-shaped blanking trough 5 in the drawings of the specification is only a display of a preferred embodiment, and the blanking trough may also be rectangular or in other shapes.

[0025] The workbench 1 is also rotatably connected to two auxiliary bending wheels 6, which are respectively located on both sides of the rear end of the bending seat. The workbench 1 is also provided with a guide groove 7;

[0026] The top of the top block 3 has a convex block 8 corresponding to the guide groove 7, and the convex block 8 passes through the bottom of the workbench 1 through the guide groove 7. A guide rail 9 is also provided on both sides of the bottom of the workbench 1. A bottom plate 10 is slidably connected between the two guide rails 9, and the rear end of the bottom plate 10 is connected to the convex block 8.

[0027] When the bottom plate 10 moves forward to the limit along with the top block 3 , the bottom plate 10 closes the bottom of the blanking chute 5 .

[0028] The working principle of the above structure is: the copper bar 14 to be bent is placed between the two auxiliary bending wheels 6, the two ends of the copper bar 14 are respectively in contact with the auxiliary bending wheels 6, the cylinder 2 is started, and the top block 3 is driven to move forward. Under the action of the two auxiliary bending wheels 6 and the top block 3, the copper bar 14 is bent into an arc and enters the bending groove 4. In this process, since the two auxiliary bending wheels 6 can rotate, the friction between the copper bar 14 and the auxiliary bending wheels 6 is small, and it is not easy to leave scratches on the copper bar 14; when the top block 3 presses the copper bar 14 tightly against the bending seat, the copper bar 14 is bent into shape; in this process, the bottom plate 10 moves forward with the top block 3, gradually closing the bottom of the blanking groove 5, so the copper bar 14 will not fall out of the workbench 1 from the blanking groove 5 during the forward bending process; after the bending is completed, the top block 3 is reset under the action of the cylinder 2, and the bottom plate 10 moves backward synchronously to expose the blanking groove 5, and the bent copper bar 14 falls from the blanking groove 5 and is discharged from the workbench 1.

[0029] The beneficial effects of the above structure are: simple structure, the copper bar 14 is automatically discharged from the workbench 1 after bending, and the conveyor belt and the limit block 13 can be used to automatically and continuously bend the copper bar 14, and it has the advantages of fast processing cycle and high efficiency. In addition, with the air nozzle arranged above the blanking chute 5, it can also prevent the bent copper bar 14 from being stuck on the blanking chute 5 and unable to fall smoothly.

[0030] Specifically, the bending groove 4 is a "concave"-shaped groove body.

[0031] In another embodiment, if Figure 1As shown, the bending seat is composed of a main body 11 and two detachable auxiliary blocks 12. The rear end of the main body 11 is a plane and is connected to the workbench 1 as a whole. The two auxiliary blocks 12 are fixed on the workbench 1 on both sides of the rear end of the main body 11. The inner side surfaces of the two auxiliary blocks 12 and the rear end surface of the main body 11 form a bending groove 4. By replacing the auxiliary blocks 12 with inner side surfaces of different shapes, the copper busbars 14 of different shapes can be bent.

[0032] In another embodiment, an air nozzle is further included, and the air outlet of the air nozzle is arranged toward the blanking chute 5. When the cylinder 2 drives the top block 3 to retract, the air nozzle sprays a high-speed airflow to blow toward the bent copper bar 14 to assist it in falling and prevent it from being stuck on the blanking chute 5.

[0033] In another embodiment, a conveyor belt is further included, and the conveyor belt is arranged on one side of the workbench 1.

[0034] In another embodiment, if Figure 1 As shown, it also includes a limit block 13, which is arranged on a side of the workbench 1 away from the conveyor belt. The limit block 13 is used to limit the copper bar 14. Multiple copper bars 14 are conveyed on the conveyor belt at the same time, and the ends of each copper bar 14 are abutted against each other. When the copper bar 14 at the front end is abutted against the limit block 13, the two ends of the copper bar 14 are located at the appropriate position and abut against the auxiliary bending wheel 6, without manual discharge, which is conducive to automation.

[0035] In another embodiment, a pressure sensor is further provided at one end of the limit block 13 facing the conveyor belt to automatically sense whether the copper bar 14 is delivered to the right position. In conjunction with the controller and corresponding programs, the conveyor belt and the cylinder 2 can be linked to further realize automated processing.

[0036] In another embodiment, if Figure 1 As shown, the workbench 1 is further provided with two guide blocks 15, which are located at one side of the workbench 1 close to the conveyor belt to guide the conveyed copper bar 14 to avoid its misalignment.

[0037] In another embodiment, if Figure 2 As shown, a slider 16 is slidably connected to each of the two guide rails 9 , and both sides of the base plate 10 are connected to the slider 16 via connecting rods 17 .

[0038] In another embodiment, a receiving box is further provided at the bottom of the workbench 1 for receiving the fallen copper busbars 14 that have been bent.
