[0028] like Figures 1 to 3 As shown, a welding head for a bending welding device includes a head frame 10, two pneumatic grippers 20, a welding clamp mechanism 30, and a welding positioning pin 14.

[0029] The head frame 10 includes a mounting plate 11, with support plates 12 on both sides of the mounting plate 11. Two pneumatic grippers 20 are vertically and vertically movable on the front side of the mounting plate 11 for clamping and moving the bent linear metal.

[0030] The welding clamp mechanism 30 is mounted on the headstock 10. The welding clamp mechanism 30 includes a fixed clamp 32 and a movable clamp 31. The front ends of the fixed clamp 32 and the movable clamp 31 are disposed through the front side of the mounting plate 11 and located between two pneumatic grippers 20. The front ends of the fixed clamp 32 and the movable clamp 31 are provided with a 33. A guide rail slider for lateral movement is provided between the movable clamp 31 and the rear of the mounting plate 11. A drive cylinder 13 connected to the movable clamp 31 is provided on the support plate 12 for driving the movable clamp 31 to move closer to the fixed clamp 32.

[0031] The welding positioning pin 14 is vertically and movable on the front side of the mounting plate 11 and is located between the fixed clamp 32 and the movable clamp 31 to ensure the accuracy and quality of the workpiece being processed, thereby improving the accuracy and efficiency of welding.

[0032] In practice, the bent and cut linear metal is gripped by two pneumatic grippers 20 and raised to the front end of the fixed clamp 32 and the movable clamp 31. The fixed clamp 32 and the movable clamp 31 clamp and contact the end of the linear metal, and cooperate with the welding positioning pin 14 to perform precise welding processing on the end of the linear metal.

[0033] like Figures 2 to 5 As shown, in this embodiment, both the movable clamp 31 and the fixed clamp 32 include an upper clamp and a lower clamp 35. The rear ends of the upper clamp and the lower clamp 35 are connected to a rocker arm cylinder mechanism, which is used to drive the upper clamp and the front end of the lower clamp 35 to make closed contact.

[0034] Specifically, the upper clamp includes an upper clamping sleeve 341, a square copper body 342, and an L-shaped bracket 343. The upper clamping sleeve 341 is fixedly connected to the rear side of the mounting plate 11. The square copper body 342 is disposed inside the upper clamping sleeve 341, and the front end of the square copper body 342 passes through the front end of the upper clamping sleeve 341 and is provided with a 33. The L-shaped bracket 343 is disposed at the rear end of the upper clamping sleeve 341.

[0035] The lower clamp 35 includes a rocker arm base 351 and a rocker arm rod 352. The front end of the rocker arm rod 352 passes through the front end of the rocker arm base 351 and is provided with a 33. The rocker arm rod 352 is provided with an elongated hole 353, and a guide post 354 connected to the rocker arm base 351 passes through the elongated hole 353.

[0036] The rocker arm cylinder mechanism includes a first cylinder 36 and a second cylinder 37. The first cylinder 36 is vertically arranged between the L-shaped bracket 343 and the rocker arm 352. The tail end of the first cylinder 36 is hinged to the L-shaped bracket 343, and the piston rod end of the first cylinder 36 is hinged to the rear end of the rocker arm 352. The second cylinder 37 is arranged parallel to one side of the rocker arm 352. The tail end of the second cylinder 37 is fixedly connected to the rocker arm 352, and the piston rod end of the second cylinder 37 is hinged to the rocker arm seat 351.

[0037] In practice, the bent and cut linear metal is gripped by two pneumatic grippers 20, rising to below the upper grippers of the fixed gripper 32 and the movable gripper 31, and contacting 33. Then, the first cylinder 36 and the second cylinder 37 operate simultaneously, causing the lower grippers 35 of the fixed gripper 32 and the movable gripper 31 to move forward and extend and lift upward through the elongated hole 353 on the rocker arm 352 and the guide post 354 passing through the elongated hole 353, so that 33 contacts the lower end of the linear metal. At this time, the welding positioning pin 14 moves upward and retracts, no longer contacting 33, thereby closing the positive and negative poles of 33, thus performing welding processing on the end of the linear metal.

[0038] In this embodiment, the movable clamp 31 is provided with a connecting slide plate 311 that is connected to the guide rail slider. The connecting slide plate 311 is connected to the guide rail slider and to the piston rod end of the drive cylinder 13, thereby causing the drive cylinder 13 to drive the movable clamp 31 to move laterally.

[0039] like Figure 1 As shown, in this embodiment, two pneumatic grippers 20 are connected to an adjusting bracket 21. The adjusting bracket 21 is connected to the front side of the mounting plate 11 via a pneumatic slider and a guide rail. The spacing and tilt angle of the two pneumatic grippers 20 can be adjusted by adjusting the adjusting bracket 21, thus making it suitable for clamping linear metals bent into different shapes.

[0040] In this embodiment, the welding positioning pin 14 moves up and down on the front side of the mounting plate 11 via a cylinder and a guide rail slider.

[0041] like Figure 1 and Figure 6 As shown, in this embodiment, a protective cover 15 is provided on the head frame 10 to protect the transmission structure inside the head frame 10.

[0042] In this embodiment, a transformer 41 chassis 40 is also included. The head frame 10 is connected to the transformer chassis via a connecting bracket. The transformer 41 chassis 40 contains a transformer 41 and a gas storage tank 42 connected to the fixed clamp 32 and the movable clamp 31.

[0043] The welding head of the bending welding equipment provided by this utility model, compared with the prior art, has a welding clamp mechanism 30 set on the head frame 10, and two pneumatic grippers 20 vertically and movable on the front side of the mounting plate 11, and on both sides of the welding clamp mechanism 30, used to clamp the bent linear metal and move it up and down, and send it between the fixed clamp 32 and the movable clamp 31 to weld the end of the linear metal. No manual intervention is required, the welding is automated, which can effectively improve the production and processing efficiency and reduce the labor intensity of workers.

[0044] Where there is no conflict, the above embodiments and features can be combined with each other.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
