Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and particularly relates to a fixing device for metal plate cutting and processing. Background Technique

[0002] As the name implies, a metal plate is a plate made of metal materials and is widely applicable to industries such as aviation, light industry, metallurgy, chemical engineering, construction, ships, automobiles, electricity, electrical appliances, and packaging.

[0003] In the process of processing metal plates, it is necessary to perform size processing on the metal plates according to their usage requirements, that is, it is necessary to cut or remove the edge materials of the metal plates by cutting. In order to avoid the reduction of processing accuracy caused by the offset of the metal plate due to the acting force of the cutting tool, it is necessary to use a clamping mechanism to position the metal plate during the cutting process.

[0004] At present, the fixing devices on metal plate cutting machines in the market are not limited. Generally, special-sized jigs are customized according to the size of the actually produced metal plates. The applicability of such jigs is not wide enough, and they cannot be flexibly adjusted according to the actual clamping situation, which cannot bring convenience to users; in addition, when cutting metal plates, it is difficult to effectively fix the metal plates, resulting in the problem of cutting line deviation during the cutting process of the metal plates; therefore, it is urgent to design a fixing device for metal plate cutting and processing to solve the above problems.

[0031] Working principle:

[0032] The utility model is used in cooperation with a plate part conveying device and a plate part cutting device. The plate part conveying device is located between two groups of feeding roller mechanisms in the rear movable guiding assembly 5 and is used to convey the plate part to the pressing plate clamping assembly 2. The plate part cutting device is located downstream of the discharge end of the pressing plate clamping assembly 2 to realize the cutting operation of the plate part;

[0033] During the actual working process, the plate conveying device used in conjunction with the present utility model conveys the plate to be cut forward. Then, after starting, the rear guiding cylinder 5-2 in the movable rear guiding assembly 5 is activated. According to the width of the conveyed plate, the distance between the two groups of feeding roller mechanisms in the movable rear guiding assembly 5 is adjusted, so that the two groups of feeding roller mechanisms are in rolling contact with the side edges of the plate. At the same time, several pressing plate guide wheels 5-3 in the rolling mechanism are in rolling contact with the top surface of the plate and elastically press it, avoiding the plate from slipping and shifting during the conveying process. At the same time, the front guiding cylinder 3-3 in the movable front guiding assembly 3 is activated, so that several front guiding wheels 3-2 in the movable front guiding assembly 3 are in rolling contact with the side surface of the plate. Through the above settings, the applicability of the present utility model is improved, enabling it to be flexibly adjusted according to the actual width of the plate, thereby realizing the positioning and clamping of the plate. The operation process is simple, providing great convenience for the staff;

[0034] When the cutting position on the plate is conveyed below the plate cutting device, the upper linear drive member 2-2 in the pressing plate clamping assembly 2 is activated, driving the upper lifting seat 2-5 to move downward, so that several pressing head mechanisms 2-7 installed thereon are in tight contact with the plate to be cut, and then pressing the plate onto the plate backing plate 2-6 installed on the lower lifting seat 2-8, realizing the clamping and fixing of the plate for subsequent cutting operations, and avoiding the problem of cutting line deviation of the metal plate during the cutting process.
