[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown in the figure, a stamping and welding fixture for disconnecting switches according to an embodiment of the present invention includes a frame 1. A forming mold 2, two stamping and welding units 3 and a cutting mold 4 are arranged sequentially from left to right on the frame 1. The frame 1 also has a power mechanism for controlling the synchronous operation of the forming mold 2, the stamping and welding units 3 and the cutting mold 4. A feeding mechanism is provided on the left side of the frame 1, which is used to transport metal strips sequentially through the forming mold 2, the stamping and welding units 3 and the cutting mold 4.

[0020] In use, the feeding mechanism conveys the metal strip through the forming mold 2, the stamping and welding unit 3 and the cutting mold 4 in sequence. The forming mold 2 processes the metal strip to form the main body of the workpiece. Then, the two stamping and welding units 3 perform two stamping and welding operations on the main body of the workpiece to form and fix the workpiece. The cutting mold 4 cuts the formed workpiece from the adhesion point of the strip to obtain the finished workpiece.

[0021] This invention achieves automated production of disconnect switch workpieces through forming mold 2, stamping and welding unit 3, and cutting mold 4, thereby improving production efficiency.

[0022] The molding die 2 is provided with punching position 20, bubble point position 21, molding position one 22, molding position two 23, molding position three 24 and molding position four 25 from left to right.

[0023] In use, punching position 20 punches the metal strip so that two pieces with the same structure are distributed on the metal strip. Bubble point position 21 pre-punches bubble points on one of the pieces. Forming positions 1 22, 23, 3 24 and 4 25 fold one of the pieces toward the other to obtain the workpiece body. The workpiece body consists of two folded pieces and a mating area that is adapted to the stationary contact is formed between the two pieces.

[0024] Among them, the aforementioned "workpiece body" is the moving contact of the existing disconnect switch, such as "13-moving contact bridge" as indicated in publication number CN118969539A.

[0025] The stamping and welding unit 3 includes a fixed base 30. The front end of the fixed base 30 is formed with a material passage 31. The bottom wall of the material passage 31 is formed with a mold base 32. A punch 33 is movably inserted through the top of the fixed base 30. The lower end of the punch 33 is formed with a lower contact portion that cooperates with the mold base 32. The upper end of the punch 33 is formed with an upper contact portion that cooperates with the power mechanism. The size of the upper contact portion is larger than the size of the punch 33. A spring member 34 is formed on the outer ring of the punch 33 between the upper contact portion and the upper surface of the fixed base 30.

[0026] When in use, the power mechanism contacts the upper contact part, and the upper contact part drives the punch 33 to slide along the fixed seat 30 against the force of the spring 34. At this time, the lower contact part completes the stamping and welding operation of the workpiece through the cooperation between the lower contact part and the die seat 32 and the preset bubble point of the workpiece body.

[0027] Among them, there are two stamping welding units 3. The two stamping welding can effectively improve the welding quality and ensure the finished product quality of the workpiece.

[0028] The cutting mold 4 is provided with a shaping position 40 and a cutting position 41 from left to right.

[0029] During use, the forming position 40 shapes the stamped and welded workpiece to ensure that it is formed in place;

[0030] The cutting position 41 cuts the formed workpiece from the adhesion point of the material strip to obtain the finished workpiece. In actual operation, a blower is installed at the cutting position 41. The blower is used to blow the cut finished workpiece out and drop it into the collection point (existing technology, not described in detail).

[0031] The feeding mechanism includes a feeding tray 5 and a feeder 50, which is installed on the left end of the upper surface of the frame 1.

[0032] In use, the unwinding tray 5 is pre-wound with a sufficient amount of metal strip. During operation, the unwinding tray 5 unwinds the metal strip, and the feeder 50 guides the metal strip and feeds it into the preset feeding channel of the equipment. The feeding mechanism ensures stable feeding of the metal strip.

[0033] The power mechanism includes a drive seat 6 slidably disposed at the front end of the frame 1 and a power motor 60 fixedly mounted on the frame 1. The output shaft of the power motor 60 is driven to connect to a turntable 61. An eccentrically mounted drive arm 62 is rotatably disposed on the turntable 61. A mating arm 63 is fixedly mounted on the top of the drive seat 6. The upper end of the mating arm 63 is rotatably connected to the drive arm 62.

[0034] During use, the upper ends of the forming mold 2 and the cutting mold 4 are connected to the drive motherboard, and the drive motherboard is equipped with contact blocks at both of the two stamping and welding units 3.

[0035] During operation, the power motor 60 drives the turntable 61 to rotate, the turntable 61 drives the drive arm 62 to move, the drive arm 62 drives the mating arm 63 to move, and the mating arm 63 drives the drive seat 6 to slide back and forth along the frame 1. The lower end of the drive seat 6 has a stamped contact plate formed. Each time the drive seat 6 slides back and forth, the contact plate contacts the drive main board once, thus completing one processing action. The power mechanism can control the forming mold 2, the stamping and welding unit 3 and the cutting mold 4 to move synchronously through a single drive source.

[0036] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.
