Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel sheets, specifically a forming device for bending cold-rolled steel sheets. Background Technology

[0002] Cold-rolled steel sheets are widely used in automobile manufacturing, home appliances, and building decoration due to their good surface quality, high dimensional accuracy, and excellent mechanical properties. In actual production, bending of cold-rolled steel sheets is a key process for realizing complex geometric shapes of parts. Through plastic deformation, the sheet material is processed into structural parts with specific angles and shapes. However, this process faces many technical challenges: springback is prone to occur during bending, resulting in deviations between the actual forming angle and the design angle, affecting the product assembly accuracy; uneven sheet thickness and material anisotropy can cause defects such as bending cracks and wrinkles, reducing the product qualification rate; at the same time, problems such as die wear and indentation can also affect the surface quality and service life of cold-rolled steel sheets. In addition, with the trend of product lightweighting and precision, higher requirements are placed on the forming accuracy, surface quality, and production efficiency of cold-rolled steel sheet bending. It is urgent to improve bending quality and production efficiency by optimizing process parameters, improving die design, and adopting advanced control technologies.

[0003] An existing forming device for bending cold-rolled steel sheets typically includes a bending frame with a feeding device on one side and a processing component on the top. When the cold-rolled steel sheet is transported onto the bending frame by the feeding device, the processing component repeatedly presses downwards, thereby bending the cold-rolled steel sheet. At the same time, the operator supports the bent cold-rolled steel sheet from one side to prevent it from springing back under its own weight, which would affect the bending effect.

[0004] However, for existing forming equipment for bending cold-rolled sheets, the cold-rolled sheets are lifted manually. The lifting operation relies on human experience, which makes it difficult to ensure the consistency of batch processing. It also increases the use of manpower and affects the working efficiency of the equipment. At the same time, workers are prone to contact with the processing components that are repeatedly pressed, which increases the safety risks during operation. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a forming device for bending cold-rolled steel sheets, so as to solve the technical problem mentioned in the background art that the existing forming devices for bending cold-rolled steel sheets have poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming device for bending cold-rolled steel sheets, comprising a mounting frame, a bending base fixedly mounted between the mounting frames, an inner groove formed in the bending base, a rotating plate movably mounted between the inner grooves, a sliding groove formed at the bottom of the rotating plate, side plates fixedly mounted on both sides of the inner groove, a limiting groove formed in the side plate, a first limiting hole formed on one side of the limiting groove, a sliding plate sleeved in the limiting groove, a first rotating cylinder movably mounted between the sliding plates, a base plate fixedly mounted in the inner groove, a motor fixedly mounted on the top of the base plate, a reciprocating lead screw provided at the output end of the motor, a slider sleeved on the reciprocating lead screw, a vertical plate fixedly mounted on the top of the slider, a protrusion fixedly mounted on the top of the vertical plate, and a second rotating cylinder movably mounted between the protrusions.

[0007] By adopting the above technical solution, the problem of poor performance of existing forming devices for bending cold-rolled sheets mentioned in the background art is solved. By incorporating a motor, when one end of the cold-rolled sheet is transported to the top of a rotating plate movably installed within the bending base, the motor is activated.

Simultaneously, it eliminates the need for manual intervention, thus reducing work efficiency.

[0014] The present invention is further configured such that the top of the rotating plate is an arc-shaped curved surface and the bottom of the rotating plate is an inclined surface.

[0015] Preferably, by setting the top of the rotating plate to an arc-shaped surface, the rotating plate can support the bent cold-rolled plate, avoiding manual intervention.

[0016] The present invention is further configured such that a second limiting hole is provided inside the sliding plate, the diameter of the second limiting hole is the same as the diameter of the first limiting hole, and a bolt is fitted between the first limiting hole and the second limiting hole.

[0017] Preferably, a second limiting hole is provided inside the slide plate, the diameter of which is the same as that of the first limiting hole. A bolt is fitted between the first and second limiting holes, so that the slide plate can be stably installed inside the side plate, and the first rotating cylinder can achieve the desired effect.

[0018] The present invention is further configured such that multiple sets of the second limiting holes are provided, and a first card plate is fixedly installed in the limiting groove.

[0019] Preferably, by opening multiple sets of second limiting holes, the height of the slide plate can be adjusted, thereby adapting to cold-rolled plates of different thicknesses and improving the practicality of the device.

[0020] The present invention is further configured such that an inclined surface is provided on the top of the first rotating cylinder, and the protrusion is fixedly installed on the inclined surface provided on the top of the first rotating cylinder, and the inclined surface is parallel to the bottom of the rotating plate.

[0021] Preferably, by providing an inclined surface at the top of the first rotating cylinder, the protrusion is fixedly installed on the inclined surface at the top of the first rotating cylinder, and the inclined surface is parallel to the bottom of the rotating plate, so that the vertical plate can better push the rotating plate, while avoiding collision between the vertical plate and the rotating plate, thereby affecting the normal use of the device.

[0022] The present invention is further configured such that the second rotating cylinder is sleeved in the slide groove, and the second rotating cylinder is fitted to the slide groove.

[0023] Preferably, by fitting the second rotating cylinder inside the slide groove and making the second rotating cylinder fit snugly against the slide groove, the second rotating cylinder can roll and push the rotating plate, which can reduce the friction during the use of the device and improve the practicality of the device.

[0024] The present invention is further configured such that a cover plate is provided on the top of the sliding plate, and the cross-sectional area of ​​the cover plate is larger than the cross-sectional area of ​​the limiting groove.

[0025] Preferably, by providing a cover plate on the top of the skateboard, the cross-sectional area of ​​the cover plate being larger than the cross-sectional area of ​​the limiting groove, a limiting effect can be achieved on the skateboard, preventing the skateboard from sliding completely into the limiting groove and thus affecting the normal use of the device.

By incorporating a motor, when one end of the cold-rolled sheet is transported to the top of the rotating plate movably installed within the bending base, the motor is started. The motor is fixedly installed... The base plate is fixedly installed in an inner groove within the bending base, allowing the slider and vertical plate to slide along the reciprocating screw. A protrusion is located on the top of the vertical plate, and a second rotating cylinder is rolled between the protrusions. The second rotating cylinder is fitted inside a groove at the bottom of the rotating plate. When the slider and vertical plate slide, the vertical plate and the second rotating cylinder push the rotating plate, causing it to rotate to one side. This supports the cold-rolled sheet being bent, preventing it from springing back under its own weight, which would affect the bending effect. It also eliminates the need for manual intervention, thus reducing work efficiency.

[0028] 2. This utility model features a side plate with a sliding plate inside. The sliding plate is fixedly installed inside the side plate by bolts. A first rotating cylinder is rolled on one side of the sliding plate and contacts one side of the cold-rolled sheet. When the plate rotates to one side, the first rotating cylinder can perform a secondary shaping effect on the cold-rolled sheet, preventing it from springing back and improving the bending effect of the device. At the same time, multiple sets of second limiting holes are opened in the sliding plate. When the thickness of the cold-rolled sheet is different, the sliding plate is slid upward to allow the bolts to be fitted into different second limiting holes, thereby adjusting the height of the first rotating cylinder. This allows the device to be used with different cold-rolled sheets, improving its practicality. Attached Figure Description
