DETAILED DESCRIPTION

[0016] Example:

[0017] The following is combined with Figure 1 The utility model is described in further detail.

[0018] Fully automatic U-shaped elbow forming machine, such as Figure 1 As shown, the main body is an iron frame 10, on which is provided a pair of clamps 20 which rotate synchronously after being powered on. The two clamps 20 are arranged opposite to each other, and the area between the two clamps 20 is a clamping area, and the glass tube 30 is clamped in the clamping area by the clamps 20.

[0019] The end of the clamp 20 is connected to the connecting rod 21, and the connecting rod 21 is mounted on the iron frame 10 through a rotating table. The rotating table can ensure the rotation of the connecting rod 21 itself. The rotating table is also rotatably connected to the iron frame 10 to ensure that the rotating table can rotate in a vertical plane. A driven gear 22 is provided at the end of the connecting rod 21, and a special rotating motor 23 is provided under the iron frame 10. The rotating motor 23 is driven by a gear set, and the driving gear 24 at the end of the gear set is meshed with the driven gear 22, and then the rotating motor 23 drives the connecting rod 21 and the clamp 20 to rotate synchronously through the driving gear 24 and the driven gear 22 of the gear set. The movement direction and rotation speed of the two clamps 20 are kept matched, and the glass tube 30 will not be twisted off.

[0020] A lifting track 52 is provided in front of the clamping area, and the lifting track 52 is installed on the iron frame 10. A corresponding lifting cylinder 51 is provided below the iron frame 10. A bend upper die 50 is provided on the lifting track 52. The bend upper die 50 has a certain length, and the rear end is provided on the lifting track 52 to ensure a flush lifting. The front end of the bend upper die 50 extends above the clamping area to ensure that it can pass through the clamping area after descending and press down the heated glass tube 30. The telescopic end of the lifting cylinder 51 is connected to the bend upper die 50. The telescopic action of the lifting cylinder 51 drives the bend upper die 50 to lift vertically along the lifting track 52. The iron frame 10 directly below the clamping area is hollow, and a blowtorch 40 that can move back and forth is provided to perform a directional and dynamic heating process on the bending area of ​​the glass tube 30.

[0021] The iron frame 10 is also provided with a traction mechanism 60, which can control the pressing down and resetting of the clamp 20. Specifically, the traction mechanism 60 includes a traction motor 61 provided on the iron frame 10, and the traction motor 61 drives the connecting rod 21 and the clamp 20 to rotate around the rotating seat through a traction rod 62. The traction rod 62 includes a plurality of mutually hinged rods, and the forward and reverse rotation of the motor drives the traction rod 62 to transmit, so that the corresponding clamp 20 is pressed down and reset.

[0022] A PLC control assembly 70 is provided next to the iron frame 10, which is electrically connected to the rotating motor 23, the blowtorch 40, the lifting cylinder 51, and the traction motor 61 to control the opening, closing, and control and adjustment of the corresponding functional units. In addition, an emergency brake unit 11 is also provided on the iron frame 10. The emergency brake unit 11 is connected to the PLC control assembly 70 and the circuits of each motor, cylinder, and blowtorch 40 to play the role of emergency power off to prevent further expansion of losses caused by accidents.

[0023] The iron frame 10 is also provided with a limit frame 25, which is located on the rotation path of the clamp 20 and plays a role in limiting and protecting the rotation of the clamp 20. The iron frame 10 is also provided with an elbow support mold 26, which is located on the bending path of the glass tube 30, that is, just below the clamping area, to temporarily store the bent glass tube 30.
