Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, and in particular to a bending and welding assembly device. Background Technology

[0002] In the manufacturing process of sheet metal parts, bending and welding are two important and frequently used processes. Taking a common sheet metal part that needs to be folded and welded as an example, during processing, firstly, the operator loads the flat blank onto the bending machine. The upper and lower dies of the bending machine work together to perform a V-shaped or U-shaped bend at a preset position. After bending, the operator needs to remove the semi-finished product from the bending machine and then transport it to another welding workstation (such as a welding robot or welding station) for reloading and repositioning. Finally, the gap formed by bending is welded by a welding torch to enhance the structural strength and rigidity.

[0003] However, a workpiece needs to go through two independent cycles of loading, positioning, processing, and unloading. The material handling between processes and the secondary alignment of the positioning reference consume a lot of time, which seriously restricts the overall production cycle and cannot meet the high efficiency requirements of modern manufacturing.

[0025] A bending and welding assembly according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0026] Reference Figure 1 The present invention aims to provide an embodiment of a bending and welding assembly device.

[0027] A bending and welding assembly device according to an embodiment of this utility model, referring to... Figure 2 , Figure 3 and Figure 5 The system includes a positioning seat 100, a bending mechanism, and a welding mechanism. The positioning seat 100 has a positioning groove 110 on its top, which is used to limit the position of the sheet metal part 310. The bending mechanism includes a die 120, a punch 130, and a press that moves the punch 130 close to the die 120. The die 120 is located in the positioning groove 110. The punch 130 and the die 120 cooperate to bend the sheet metal part 310. The welding mechanism includes a laser welding gun 140 and a proximity switch 150. The laser welding gun 140 is located in front of the die 120 and is electrically connected to the proximity switch 150. The proximity switch 150 is located below the punch 130. When the sheet metal part 310 is bent, the proximity switch 150 can detect the punch 130, so that the laser welding gun 140 can weld the sheet metal part 310.

[0028] It is understood that this utility model, by setting up a positioning seat 100, a die 120, a punch 130, a press, and a laser welding gun 140, places the sheet metal part 310 on the positioning groove 110 of the positioning seat 100, so that the sheet metal part 310 is in the stamping position. Under the drive of the press, the punch 130 descends and approaches the die 120, and can cooperate with the die 120 to stamp the sheet metal part 310, so that the sheet metal part 310 forms a V shape. Then, the laser welding gun 140 welds the gap at the fold position. Thus, the bending and welding functions are integrated into one station, and the sheet metal part 310 can complete the bending and welding steps in one clamping. This eliminates the time spent on secondary loading, positioning, and handling in the traditional mode, improves production efficiency, and eliminates the need for a separate welding workstation, which greatly reduces the equipment footprint and reduces the overall equipment investment and workshop space costs.

[0029] Furthermore, by setting a proximity switch 150, the present invention automatically triggers the laser welding gun 140 to perform laser welding by detecting the position of the punch 130, thereby achieving a seamless and precise connection between the bending action and the welding action. This ensures that the welding is always performed at the same precise position formed by the bending, significantly improving product consistency.

[0030] In some embodiments of this utility model, a feeding mechanism is also included. The feeding mechanism includes a pusher plate 270 and a linear moving module 280 that drives the pusher plate 270 to move horizontally. The pusher plate 270 is slidably disposed in the positioning groove 110. The pusher plate 270 can push the sheet metal part 310 onto the die 120.

[0031] Understandably, the linear motion module 280 drives the pusher plate 270 to perform precise feeding actions, eliminating the need for manual movement of the sheet metal part 310 to the stamping and bending position, thus improving operational safety.

[0032] In some embodiments of this utility model, a crossbar 290 is provided on the left or right side of the punch 130, and a metal rod 300 is provided at the end of the crossbar 290. The proximity switch 150 has a horizontally arranged detection end, which is used to detect the metal rod 300.

[0033] Understandably, by setting the metal rod 300 on the punch 130, the metal rod 300 can move down with the punch 130 and be detected by the horizontal detection end of the proximity switch 150. When the punch 130 bends, the proximity switch 150 can detect the signal. Welding will only be triggered after the punch 130 is in place, which prevents malfunctions and ensures the correct process sequence.

[0034] In some embodiments of this utility model, the top of the concave mold 120 has a V-groove 160, and the bottom of the convex mold 130 is provided with a V-shaped portion 170, which cooperates with the V-groove 160.

[0035] Understandably, the V-shaped portion 170 of the punch 130 and the V-shaped groove 160 of the die 120 cooperate to precisely control the bending angle and bending radius of the sheet metal part 310, resulting in high forming quality and good consistency. Furthermore, it reduces the possibility of positional displacement of the sheet metal part 310 after bending.

[0036] In some embodiments of this utility model, an unloading mechanism is also included. The unloading mechanism includes a support rod 180, a tilting frame and a power component. Support rods 180 are provided on the left and right sides of the punch 130. The tilting frame is connected to the support rods 180. The power component is used to drive the tilting frame to rotate, so that the support rods 180 can drive the sheet metal part 310 to disengage from the positioning groove 110.

[0037] Understandably, after bending and welding are completed, the unloading mechanism can drive the tilting frame to rotate via a power component. The support rod 180 follows the tilting frame, so that the two support rods 180 automatically lift the finished part out of the positioning slot 110, realizing automated unloading, avoiding burns or bumps that may be caused by manual handling, and improving the safety of the operation.

[0038] In some embodiments of this utility model, the top of the positioning seat 100 is provided with a strip groove 190, which accommodates the support rod 180.

[0039] Understandably, the strip groove 190 provides movement space for the support rod 180, allowing it to be hidden inside the positioning seat 100 when not in operation, and to rise smoothly to complete the ejection action when in operation, ensuring no movement interference between the unloading mechanism and the positioning seat 100 and the die 120, and ensuring reliable operation of the equipment.

[0040] In some embodiments of this utility model, reference is made to Figure 3 and Figure 4 The unloading mechanism includes a support 200, a tilting frame is rotatably mounted on the support 200, and a power component has a first cylinder 210, one end of the first cylinder 210 is hinged to the support 200, and the other end of the first cylinder 210 is hinged to the tilting frame.

[0041] Understandably, using a cylinder as the power component, with the first cylinder 210 hinged to the tilting frame and the support 200, can provide a smooth and sufficient torque to drive the support rod 180 to complete the unloading action. The structure is simple, the response is fast, and the control is convenient.

[0042] In some embodiments of this utility model, the flipping frame has a rotating shaft 220 and a positioning plate 230 fixedly disposed on the rotating shaft 220. The rotating shaft 220 is rotatably connected to the bracket 200. The positioning plate 230 is connected to the support rod 180 and is used to form one side wall of the positioning groove 110.

[0043] Understandably, the positioning plate 230 serves both as the sidewall forming the positioning groove 110 to limit the position of the sheet metal part 310 and as a connector for the support rod 180, simplifying the overall structure and improving the rigidity and reliability of the equipment.

[0044] In some embodiments of this utility model, the positioning plate 230 is provided with a clearance hole 240, which allows the medium ejected by the laser welding gun 140 to pass through.

[0045] Understandably, the clearance hole 240 provides a clear laser path for the laser welding gun 140, ensuring that the laser can act on the weld seam without obstruction and perpendicularly, avoiding the risk of collision with surrounding components, and ensuring the stability of the welding process and the quality of the weld seam.

[0046] In some embodiments of this utility model, reference is made to Figure 2 and Figure 3 A chute 250 is provided on one side of the tilting frame, and a receiving box 260 is provided below the chute 250. The receiving box 260 is used to collect the processed products.
