Description

Technical Field

[0001] This utility model relates to the technical field of metal sheet bending machines, specifically a metal sheet processing bending machine. Background Technology

[0002] Metal sheets are flat products made primarily from metallic materials. They possess excellent mechanical properties, corrosion resistance, and decorative properties, and are widely used in construction, manufacturing, transportation, electronics, energy, and other fields. Metal sheets can be made from different metallic materials, such as aluminum, steel, copper, and zinc. These different metallic materials have different characteristics and applications, thus finding wide applicability in various fields. The manufacturing process of metal sheets generally includes raw material preparation, sheet rolling, surface treatment, and cutting. In the raw material preparation stage, the required metallic materials are selected and undergo rigorous quality inspection to ensure product quality. During the rolling process, the metallic material is continuously pressed and stretched to form metal sheets of the required dimensions.

[0003] Metal sheets have a wide range of uses in daily life. When metal sheets are used in different occasions, they need to be processed into specific shapes. Bending is a common processing method. When bending metal sheets, metal sheet bending machines are often used for bending processing.

[0004] When a common CNC bending machine bends sheet metal, it often requires workers to lift the sheet metal. When the workload is large, it will put a heavy burden on the workers, which is time-consuming and laborious. Especially when dealing with long and heavy sheet metal, it is very inconvenient for workers to lift it, and it is also quite laborious to move the metal sheet manually.

[0005] In view of this, this technical solution proposes a metal sheet bending machine to better solve the problems mentioned above. Utility Model Content

[0006] The technical solution adopted by this utility model is as follows: a metal sheet processing bending machine, including a bending machine body, an upper die cutter head and a lower die arranged opposite to each other on the bending machine body, a bending lower die die on the lower die, and a lifting mechanism for auxiliary cooperation with the bending lower die die on the side of the bending machine body.

[0007] The lifting mechanism includes a mounting plate, which is fixed to the side of the bending machine body by a fixing bolt. A support plate is fixed to the front of the mounting plate, and a bullseye bearing is fixed to the lower part of the support plate. A protective plate is installed on the top of the support plate by a fixing bolt, and a bullseye bearing ball placement slot is provided inside the protective plate relative to the bullseye bearing. The bullseye bearing ball placement slot is movably fitted onto the balls of the bullseye bearing.

[0008] The bottom of the support plate is fixed with a support screw, and the support screw is threaded with a support inner thread sleeve. The bottom end of the support inner thread sleeve is rotatably mounted with a support plate that is used on the ground.

[0009] In a preferred embodiment, the bullseye bearing is linearly disposed inside the lower part of the support plate, and the bullseye bearing is fixed to the lower part of the support plate by bolts.

[0010] In a preferred embodiment, the protective plate and the support plate have the same length and width, and the top of the protective plate and the mounting plate are located on the same horizontal plane.

[0011] In a preferred embodiment, the number of the bullseye bearing ball mounting slots is the same as the number of bullseye bearings, and the bullseye bearing ball mounting slots are through slot structures.

[0012] In a preferred embodiment, a flange is fixed to the upper end of the support screw, and the flange is fixed to the bottom of the support plate by three fixing bolts.

[0013] In a preferred embodiment, the support disc is mounted on the bottom end of the internal threaded support sleeve via a bearing, and the internal threaded support sleeve is adapted to the support screw.

[0014] In a preferred embodiment, the bottom of the support plate is fixed with an anti-slip pad, and the anti-slip pad is an anti-slip rubber pad.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates better support and lifting of the metal sheet that needs to be bent, and allows for better positional movement of the metal sheet that needs to be bent, saving manpower and increasing work efficiency.

[0016] 1. In this utility model, the mounting plate can be fixed to the side of the bending machine body by fixing bolt one. At this time, the installation height of the mounting plate should ensure that the metal plate placed on the bullseye bearing can be better pushed onto the bending die for bending. After the mounting plate is fixed, the position of the support plate is also fixed. Then, the flange is fixed to the bottom of the support plate by fixing bolt three. Finally, by rotating the inner threaded sleeve of the support, the anti-slip pad fixed at the bottom of the support plate is supported on the ground. At this time, the cooperation of the support screw, the inner threaded sleeve of the support, and the support plate can provide better support for the support plate.

[0017] 2. In this utility model, when the bullseye bearing is damaged and needs to be replaced, the fixing bolts 2 are removed from the inside of the support plate and the protective plate, and the protective plate can be removed from the support plate. At this time, the damaged bullseye bearing inside the support plate can be replaced. Attached Figure Description
