Description

Technical Field

[0001] The present application relates to the technical field of network cabinet production, and more specifically, to a multi-specification L-shaped bracket processing device using a common continuous mold. Background Art

[0002] The processing of L-shaped brackets used in traditional network cabinets generally uses CNC typesetting and cutting, followed by bending and subsequent processing. This method requires CNC programming, typesetting, cutting and then burr removal, and the production efficiency is low. The existing processing method of using continuous molds to process L-shaped brackets has improved the processing efficiency.

[0003] A progressive die, also known as a progressive die or a step die, is a cold stamping die that uses a strip of raw material to complete multiple stamping processes simultaneously by setting up multiple different stations on a die in one stamping stroke of the stamping machine. In a continuous die, the blanking parts are formed step by step. By concentrating the process, multiple processes such as trimming, notching, grooving, punching, plastic deformation, and blanking can be completed continuously. The design of this die allows a die to complete multiple processes, which not only improves production efficiency, but also reduces the number of equipment and workshop area, and eliminates the transportation and storage of semi-finished products. The positioning and guiding devices of the continuous die ensure the quality and precision of the stamped parts.

[0004] Since each process of the progressive die is completed at a different workstation, the cumulative positioning error will affect the accuracy of the workpiece, so the accuracy of the L-shaped bracket produced in the actual production process is not as good as expected. Utility Model Content

[0009] Through the above technical solution, the slider is driven to slide in the slide groove by adjusting the screw rod, thereby adjusting the distance between the two limit baffles, which can adapt to material strips of different widths.

[0010] Furthermore, the front ends of the two adjusting screws are fixedly connected with gears that can mesh with each other, and at least one of the gears is fixedly connected with an adjusting handle.

[0011] Through the above technical solution, by rotating the adjusting handle, the two adjusting screws can be rotated simultaneously, thereby driving the two sliders to slide simultaneously, thereby realizing the synchronous adjustment of the relative distance between the two limit baffles.

[0012] Furthermore, the material moving assembly includes a material moving roller, a pressure holding wheel and a driving motor. A roller groove is provided on the base. The material moving roller is horizontally rotatably connected in the roller groove, and the roller surface of the material moving roller protrudes 1-2 mm from the top surface of the base.

The pressure holding wheel is rotatably connected to the inner side of the limit baffles on both sides corresponding to the position of the material moving roller.

[0013] Through the above technical solution, the material belt passes through between the material transfer roller and the holding wheel, and the material belt is driven by the rotation of the material transfer roller to be transmitted to the continuous mold, thereby achieving stable loading.

[0014] Furthermore, two groups of the material transfer rollers and the pressure holding wheels are provided, and the inner shaft ends of the two material transfer rollers are connected by a synchronous pulley.

[0015] The above technical solution can improve transmission stability.

[0016] Furthermore, the surfaces of the material transfer roller and the pressure holding wheel are both made of rubber.

[0017] Through the above technical solution, the contact friction with the material strip is improved.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] The present application uses a combination of a material shifting assembly and a limiting assembly to improve the stability of material loading on a punching machine, effectively avoid the cumulative positioning error of a continuous die, and further improve the production quality; by adjusting the screw to drive the slider to slide in the slide groove, it is convenient to adjust the distance between the two limiting baffles, and can adapt to material strips of different widths to achieve the sharing of multiple specifications of L-shaped brackets, which is highly practical.
