Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic bracket installation, and in particular relates to a pneumatic bending machine for a simple photovoltaic bracket connector. Background Art

[0002] Photovoltaic brackets are used to mount photovoltaic panels. Since photovoltaic panels are often laid over a large area to maximize solar energy, they are often assembled from a large number of panels. The photovoltaic panels are then mounted on photovoltaic brackets.

[0003] The installation position between the photovoltaic bracket and the photovoltaic panel is a bending setting, that is, the photovoltaic bracket has a bending structure, which facilitates multi-sided fastening of the photovoltaic panel.

[0004] Currently, photovoltaic brackets are bent by using a bending machine to form a bent structure by stamping. Specifically, during the stamping process, a hydraulic cylinder is used to drive the stamping die head to impact the mold and form a bent structure.

[0005] However, firstly, traditional stamping equipment mostly uses hydraulic stamping, and the stamping speed is relatively slow. Secondly, the mechanical structure of traditional stamping equipment is too complicated, and the operation flexibility is relatively poor during operation. This is reflected in the fact that during operation, the photovoltaic bracket blank is first loaded onto the mold and positioned. After positioning, the control switch is turned on, and the hydraulic cylinder is slowly pressed down to achieve stamping and bending of the blank.

[0006] Therefore, traditional hydraulic bending equipment not only has low processing efficiency, but also has poor operational flexibility and cannot meet the needs of mass production in workshops. Utility Model Content

[0007] Based on the above background, the purpose of the present invention is to provide a simple pneumatic bending machine for photovoltaic bracket connectors.

[0040] Example 1

[0041] like Figure 1-4 As shown, a simple pneumatic bending machine for photovoltaic bracket connectors includes a bending machine frame 2, on which a pneumatic bending mechanism 3 is assembled and connected. A bracket 21 is installed at the bottom of the bending machine frame 2 for supporting the entire device.

[0042] The specific structure of the pneumatic bending mechanism 3 is as follows:

[0043] The pneumatic bending mechanism 3 includes two cylinders 31 spaced apart from each other (cylinder barrels of the cylinders 31 are mounted on the bending machine frame 2 ), and each of the cylinders 31 is equipped with a driving arm assembly 32 .

[0044] Specifically, the drive arm assembly 32 includes a hinged member mounted on the piston rod of the cylinder 31. The hinged member comprises a lower hinged seat 321 fixedly mounted on the piston of the cylinder 31. A hinged rod 322 is hingedly connected to the lower hinged seat 321, and a pair of drive arms 323 are hingedly connected to the upper and lower ends of the hinged rod 322. The hinged member is hingedly connected to the lower hinged seat 321 and the drive arms 323 via a pin.

[0045] A connecting shaft 324 is fixedly connected between the driving arms 323 , and shaft sleeves 325 are hinged at both ends of the connecting shaft 324 . A vertical guide structure 33 is fixedly connected between the shaft sleeves 325 . The vertical guide structure 33 is vertically lifted and lowered by the driving arms 323 .

[0046] Specifically, first, under the lifting drive of the cylinder 31, a connecting rod mechanism is formed between the hinge and the driving arm 323; when the cylinder 31 pushes the hinge, the driving arm 323 flips and drives the connecting shaft 324 downward, and the two ends of the connecting shaft 324 are hinged with shaft sleeves 325, and the shaft sleeves 325 are fixed on the vertical guide structure 33, so the lifting movement of the cylinder 31 is switched to the lifting movement of the vertical guide structure 33 through the vertical guide structure 33.

[0047] Specifically, the vertical guide structure 33 includes a U-shaped lifting arm 331 fixedly connected between the shaft sleeves 325. The front side walls of the U-shaped lifting arm 331 are slidably connected to fixed seats 332 (fixed seats 332 are fixedly mounted on, for example, a machine platform via a plurality of bolts). The sliding mechanism is as follows: the front side arms of the U-shaped lifting arm 331 are each provided with a slide groove, and the fixed seat 332 is fixedly connected to a slide plate that slides within the slide groove.

[0048] At the same time, a bending tool 34 is fixedly installed on the bottom of the U-shaped lifting arm 331.

[0049] Therefore, driven by the air cylinder 31 , the bending tool 34 finally moves up and down.

[0050] The above method realizes a linkage mechanism formed by a simple cylinder 31, a drive arm 323, and an articulated structure to achieve the raising and lowering of the bending tool 34. This structure is not only simple but also highly flexible. In actual operation, during the bending process of the blank, the highly flexible bending tool 34 can achieve rapid bending processing. Compared with the low efficiency, slow speed, complex equipment structure, and high failure rate of traditional hydraulic presses, the high flexibility of the above structure shows higher production efficiency and greater convenience of equipment use.

[0051] Example 2

[0052] like Figure 1-4 As shown, this embodiment is based on the structure of Example 1, and a bending die 35 that cooperates with a bending tool 34 is installed on the bending machine frame 2. The bending die 35 includes die plates 351 spaced apart on both sides; the die plates 351 are installed on the bending machine frame 2 (specifically, connecting plates 36 are respectively clamped between the left and right ends of the die plates 351, and the connecting plates 36 are fastened to the bending machine frame 2 by bolts); a bending groove 352 is formed between the die plates 351.

[0053] A vertical guard plate 21 adapted to the bending tool 34 is installed on the top of the bending machine frame 2; the vertical guard plate 21 is located above the rear mold plate 351.

[0054] During the working process, when the bending tool 34 is descending, the bracket blank placed on the mold plate 351 is bent under the stamping of the bending tool 34. During the bending process, the bracket produces a vertical surface due to bending, and the vertical surface is supported on the vertical guard plate 21. The verticality of the vertical surface is maintained under the resistance of the vertical guard plate 21, thereby maintaining the regular shape of the bent structure after bending.

[0055] Example 3

[0056] like Figure 1-4 As shown, based on the structure of Example 1, in order to increase the flexibility of controlling the cylinder 31 during operation, a foot pedal mechanism 1 for controlling the operation of the cylinder 31 is provided below the bending machine frame 2 in accordance with the existing method. Specifically, the foot pedal mechanism 1 includes a foot pedal 11. Similar to the existing method, the operator controls the opening and closing of the air circuit of the cylinder 31 by stepping on the foot pedal 11, thereby controlling the operation of the cylinder 31.

[0057] Specifically, similar to the existing method, the foot pedal 11 controls the opening and closing of the valve on the air circuit of the cylinder 31 through a connecting rod and other structures, thereby realizing foot-operated control of bending, thereby increasing the production flexibility of bending.

[0058] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
