Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of profile processing, in particular to a precision sawing system for ultra-thin profiles. BACKGROUND

[0002] In the existing finished product sawing field, single-head saws dominate. However, when faced with the processing of ultra-thin aluminum profiles, single-head saws expose a series of serious problems, such as extremely short saw blade life and extremely low processing efficiency. The sizing method of the finished product saw of the traditional extruder relies on sizing baffle to control the length of the profile. However, this method has many defects. For example, when the profile hits the sizing baffle, it will cause serious scratches on the profile cross section, and also cause the profile to rebound, resulting in serious sizing accuracy errors. In addition, the sizing baffle slides through a linear bearing guide, and after the sizing baffle position is adjusted in place, it is fixed by a jack screw. However, the jack screw is prone to looseness, causing the sizing baffle to shift, thereby causing the sizing length to not meet the production requirements, seriously affecting product quality and production efficiency. SUMMARY

[0003] The technical problem to be solved by the present application is to provide a precision sawing system for ultra-thin profiles, which ensures product positioning accuracy while improving production efficiency.

[0004] To solve the above technical problems, the technical scheme adopted by the present application is:

[0005] A precision sawing system for ultra-thin profiles, comprising a feeding device, a clamping and positioning device, and a sawing device arranged in sequence along a first direction.

[0006] The clamping and positioning device comprises a rack, a movable clamping mechanism, and a fixed clamping mechanism.

[0007] The fixed clamping mechanism is arranged at one end of the rack close to the feeding device, and is used to clamp the ultra-thin profile.

[0008] The movable clamping mechanism is in sliding connection with the rack, is located on the side of the fixed clamping mechanism away from the feeding device, and can clamp the ultra-thin profile and move back and forth between the fixed clamping mechanism and the sawing device.

[0009] The present application has the following advantages: through the cooperation of the feeding device, the movable clamping mechanism, and the fixed clamping mechanism, the ultra-thin profile is quickly positioned and fed. Due to the arrangement of the movable clamping mechanism, the feeding distance of the ultra-thin profile can be accurately controlled, i.e., the cutting length of the ultra-thin profile is controlled. No sizing baffle is needed, which protects the ultra-thin profile. Moreover, due to the cooperation of the movable clamping mechanism and the fixed clamping mechanism, the cutting efficiency of the ultra-thin profile is greatly improved.
