Description

Bamboo chip curved surface cold bending shaping device and method Technical Field The invention relates to the technical field of cold bending processing, in particular to a bamboo chip curved surface cold bending shaping device and method. Background The cold roll forming is a high-efficiency metal plastic processing technology, and the metal strip is progressively and continuously bent through a plurality of pass forming rollers which are sequentially arranged, so that the required complex cross-sectional shape is finally obtained, and the cold roll forming technology is widely applied to manufacturing of products such as building steel structures, automobile parts, furniture, storage shelves and the like. Conventional cold-roll forming apparatus typically includes a frame, a drive system, and a plurality of sets of forming frames arranged sequentially along a production line. Each group of the forming frames is provided with one or more pairs of horizontal or vertical forming rollers, and the rollers are provided with holes matched with the local shape of the section of the target section. The strip material is clamped and guided by the rollers and sequentially passes through each pass roller set, and the cross section shape of the strip material is gradually bent and formed. However, when the common bamboo sheet curved surface cold-bending shaping device and method are used in daily life, problems usually exist, along with development of technology, a great deal of optimization is performed on the bamboo sheet curved surface cold-bending shaping device and method by technicians in the related field to solve part of problems of different consumers, and in order to perform more accurate comparison, for example, chinese patent publication No. CN220329674U discloses an aluminum profile cold-bending device, which comprises a device main body and a cold-bending part, a limit box is arranged above one end of the device main body, a limit frame is arranged at one end of the limit box, protruding side plates are arranged at two sides of one end of the limit box, and limit rollers with different diameters are arranged inside the limit frame. The aluminum profile can be propped against the aluminum profile by downwards pressing the pressing plate through the electric telescopic rod after being placed in the limiting box, and further, the two sides of the aluminum profile are limited by the clamping plate and the blocking pad, so that one end of the aluminum profile can be limited during cold bending, one end of the aluminum profile is fixed during bending, the other end of the aluminum profile rotates along with the bending, simultaneous inward shrinkage of two ends can be effectively avoided, the precision of a machining position can be guaranteed, the situation of swinging of the end position can be prevented, the production quality of a product can be guaranteed, and the use effect can be improved. However, the aluminum profile cold bending device has some defects in the actual use process: 1. according to the aluminum profile cold bending device, the aluminum profile can be pressed down by the electric telescopic rod to prop against the aluminum profile after being placed in the limiting box, and then the two sides of the aluminum profile are limited by the clamping plate and the blocking pad, but the aluminum profile cold bending device cannot change along with the width change of the material when clamping the material, and only the material with a specific width can be processed. 2. According to the aluminum profile cold bending device, the electric screw is utilized to drive the limiting frame and the limiting rollers to be adjusted to different using heights through the spiral sleeve, so that the upper ends of the limiting rollers with different diameters are flush with the transmission mechanism inside the limiting box, but the aluminum profile cold bending device cannot be used for fixing materials well during processing, and therefore the materials vibrate in the processing process. Therefore, under the above stated viewpoints, the existing bamboo sheet curved surface cold-bending shaping device, method and method can also have an improved space.
