Description

Technical Field

[0001] This utility model relates to the field of sheet metal stamping, and more specifically, to a sheet metal composite stamping forming machine. Background Technology

[0002] Sheet metal work is a comprehensive cold processing technology for thin metal sheets. Patent publication number CN215614612U discloses a sheet metal composite stamping forming machine, including a stamping machine body. A hydraulic cylinder is fixedly connected to the bottom of the upper part of the stamping machine body, and a pressure plate is fixedly connected to the moving end of the hydraulic cylinder. A processing table is fixedly connected to the top of the lower part of the stamping machine body. A feeding box is opened on one side of the lower part of the stamping machine body and on the other side of the processing table. A first fixing block is fixedly connected to the bottom of the feeding box, and a material blocking mechanism is slidably connected to the top of the first fixing block. A third electric telescopic rod is fixedly connected to the inner side wall of the feeding box. Multiple first sliding grooves are opened on the top of the lower part of the stamping machine body, and multiple feeding mechanisms are slidably connected to the top of the lower part of the stamping machine body above the first sliding grooves. This invention, by installing multiple feeding mechanisms, can realize automatic clamping and unloading of workpieces, effectively improving efficiency and saving costs.

[0003] In existing technologies, although electric telescopic rods are used to extend and retract the position of electromagnets, this method of adjusting the position inevitably requires two adjustments in sequence during the movement process, and the adjustment time is relatively long. Therefore, it takes a lot of time in the mass stamping process of sheet metal parts. Therefore, there is a need for a feeding device that can make curved movements during the movement of the telescopic rod, and can rotate the adsorption surface of the electromagnet to adapt to the processing requirements of more different sheet metal parts.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Example 1:

[0030] Please see Figure 1-5 A sheet metal composite stamping forming machine includes a processing table 1, a stamping die 2 is arranged above the processing table 1, a feeding device 3 is slidably installed on the top of the processing table 1, a horizontal partition 4 is fixedly installed on the inner side of the top of the feeding device 3, a first telescopic rod 5 is movably installed on one side of the horizontal partition 4, a second telescopic rod 7 is fixedly installed on the outer end of the first telescopic rod 5, an electromagnet 8 is rotatably installed on the bottom end of the second telescopic rod 7, a cross-shaped right-angle mounting bracket 6 is detachably installed on the surface of the first telescopic rod 5, a bolt 601 is installed on the internal thread of the outer end of the cross-shaped right-angle mounting bracket 6, and a worm gear 602 is fixedly installed on the side of the cross-shaped right-angle mounting bracket 6.

[0031] It should be noted that the processing table 1 and the stamping die 2 in this application are both existing structures in the prior art documents. The first telescopic rod 5 and the second telescopic rod 7 are also existing structures. Therefore, the connection method and start-up process of these structures will not be described in detail in this application.

[0032] A motor 401 is fixedly installed inside the transverse partition 4. A pulley 402 is fixedly sleeved on the output shaft of the motor 401. A belt 403 is driven onto the surface of the pulley 402. A limit frame 404 is fixedly installed on the outer side of the transverse partition 4. A limit disc 405 is rotatably installed inside the limit frame 404. A worm 406 is fixedly installed on the inner side of the limit disc 405. A pulley 407 is fixedly installed on the outer end of the worm 406. The surfaces of the worm 406 and the worm wheel 602 mesh with each other. There are two pulleys 407. The two pulleys 407 and the pulley 402 are arranged in an equilateral triangle shape and are both in contact with the same belt 403. A rotating frame 408 is fixedly installed on the outer side of the transverse partition 4. A support shaft 409 is fixedly installed in the middle of the rotating frame 408. The rotating frame 408 and the worm wheel 602 are rotatably connected. The support shaft 409 is rotatably installed in the middle of the worm wheel 602.

[0033] Specifically, the support shaft 409 is used to support the rotation of the two worm gears 602, thereby improving their service life. Secondly, the equilateral triangular distribution structure of the pulley 402 and the belt 407 ensures that the triangle of the belt 403 is at an effective transmission angle, preventing slippage due to insufficient wrap angle of the belt 403 and affecting the transmission effect. The bolt 601 effectively fixes the cross-shaped right-angle mounting bracket 6 and the first telescopic rod 5, achieving synchronous movement and ensuring stability during movement.

[0034] The top of the electromagnet 8 is fixedly equipped with an elastic locking tooth 801, the top of the electromagnet 8 is fixedly equipped with a fixing plate 802, the middle of the fixing plate 802 is fixedly equipped with a rotating shaft 803, the surface of the rotating shaft 803 is rotatably equipped with a fixing tooth ring 804, the top of the fixing tooth ring 804 is fixedly equipped with a fixing rod 805, the top of the fixing rod 805 is fixedly installed at the bottom of the second telescopic rod 7, and the shape of the elastic locking tooth 801 is adapted to the external shape of the fixing tooth ring 804.

[0035] Specifically, by utilizing the elastic properties of the elastic teeth 801, it can be effectively made to have deformation function during rotation and movement, and can be fixed by the meshing of the teeth when no external force is applied, thereby improving the overall speed of movement of the electromagnet 8.

[0036] The working principle of this utility model is as follows: For different types of sheet metal parts, and when they need to be adsorbed in different positions, the motor 401 can be started to drive the pulley 402 to rotate in conjunction with the belt 403 to drive the other two pulleys 407 to rotate. In conjunction with the worm gear 406, the worm wheel 602 is driven to rotate, so that the cross-shaped right-angle mounting bracket 6 drives the first telescopic rod 5 to change angle. This allows the position of the electromagnet 8 to change in a curve. Then, the electromagnet 8 can be rotated according to the required plane angle of adsorption, so that the elastic locking teeth 801 enter the appropriate position and engage with the meshing teeth of the fixed tooth ring 804 to complete the fixed engagement.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
