Description

Technical Field

[0001] The present invention relates to the field of profile processing, and in particular to a profile bevel cutting device. Background Art

[0002] Aluminum profiles are die-extruded cross-sections that require further processing, including sawing, punching, grooving, stamping, and turning, before they can be used. Currently, miter cutting methods for profiles on the market typically utilize a rotatable saw blade mechanism. These methods also limit the cutting angles of the profiles or pipes to 45-90 degrees. Materials with angles less than 45 degrees cannot be sawed and must be cut manually with an angle grinder. This results in low efficiency, low safety factors, large tolerances, and poor product quality. Therefore, improving sawing flexibility and enabling multi-angle bevel cutting, especially for profiles below 45°, is a topic worthy of research. Summary of the Invention

[0018] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings:

[0019] like Figures 1 to 4 The present invention shows a device for bevel cutting of profiles, which comprises two workbenches 1, which are placed adjacent to each other at a right angle. Each of the workbenches 1 is equipped with a slide 2 and a slide drive mechanism 3 for driving the slide 2 to perform horizontal linear sliding motion. Each of the slides 2 is equipped with a clamping mechanism 4 and a liftable sawing mechanism 5.

[0020] The clamping mechanism 4 includes a base 41, a movable clamp 42, a fixed clamp 43 and a linear cylinder 44 for driving the telescopic movement of the movable clamp, the movable clamp 42 has a movable clamp clamping surface 421, the fixed clamp 43 has a fixed clamp clamping surface 431, and the movable clamp clamping surface 421 is opposite to the fixed clamp clamping surface 431; the base 41 is rotatably mounted on the slide 2, a clamp mounting seat 45 is fixedly mounted on the base 41, and a dust cover 46 is installed between the clamp mounting seat 45 and the base 41; the linear cylinder 44 is mounted on the clamp mounting seat 45, the movable clamp 42 is fixed on the free end of the piston rod 441 of the linear cylinder, a slide groove 422 is provided at the bottom of the movable clamp 42, the slide groove 422 is slidably matched with the clamp mounting seat 45, and the upper surface of the movable clamp 42 is detachably mounted with a A pad 423 is provided to increase the vertical thickness of the movable clamp, and a slot 424 is provided on the movable clamp 42 to make room for the saw blade, and the slot 424 is located on the back of the clamping surface 421 of the movable clamp; the clamp mounting seat 45 extends an extension platform 451 horizontally outward from the clamping surface 421 of the movable clamp, and the fixed clamp 43 is fixedly installed on the extension platform 451, and the extension surface of the fixed clamp clamping surface 431 passes through the rotation axis of the base 41, and the fixed clamp clamping surfaces 431 of the two clamping mechanisms are on the same plane, and anti-slip textures are provided on the fixed clamp clamping surface 431 and the movable clamp clamping surface 421; the upper surface of the extension platform 451 has a boss 452 for placing the profile 10 to be cut, and the boss 452 is also located below the fixed clamp clamping surface 431 and the movable clamp clamping surface 421.

[0022] The two workbenches of the profile bevel cutting device implemented in this embodiment are vertically arranged. The two ends of the profile to be cut are placed on the two bosses to form a right triangle with the workbench. When the angle to be cut is determined, the distance between the two right-angled sides formed by the two ends of the profile to be cut and the workbench on the slide is adjusted.
