Description

Complicated section aluminium alloy terminal surface chamfer processing equipment

Technical Field

The utility model relates to a metal machining technical field specifically is a complicated section aluminium alloy terminal surface chamfer processing equipment.

Background

Aluminum profiles are industrial materials of aluminum alloys produced by hot extrusion, and are widely used in various aspects of life due to their excellent characteristics of light weight, corrosion resistance, easy recovery, and the like. The aluminum profile is processed into handles and frames of household appliances and automobile bodies, and the structural member is also a common application field of the aluminum profile. In the application, the aluminum alloy section is subjected to fixed-length sawing in the extrusion production process, so that the end faces of the aluminum section are all sawn faces, the sawn faces are rough, burrs and rough faces of the end faces need to be removed and chamfered in the subsequent finish machining process of workpieces on the aluminum section, and especially for household appliance parts, such as handles, frames and other exterior trimming parts, the requirements on end face chamfering of aluminum section workpieces are very strict.

The end face chamfer of the traditional aluminum profile workpiece is usually formed by polishing through a grinding machine and a grinding wheel belt, and workers hold an aluminum profile by hands and approach the end face of the aluminum profile to the surface of the grinding machine or the grinding wheel belt at a certain angle to rub and remove burrs and sharp corners; the other method is that an operator adopts a file or a scraper to manually chamfer the end surface of the aluminum profile, and the aluminum profile chamfered by the method has the following defects: 1. for the section bar with a complicated section, particularly the section bar with a plurality of protruding ribs, the end face chamfering can only be performed by adopting a file or scraper chamfering mode basically, the working efficiency is low, and the section bar-by-bar operation is required; meanwhile, due to pure manual operation, workers are easy to fatigue, the working strength is high, and stable large-scale production is not facilitated. 3. The chamfer that pure manual work came out is not of uniform size, has great error, and size precision is low: for example, in the drawings, the chamfer angle is required to be 0.5mm and 45 degrees, and the chamfer size and the chamfer angle are always deviated due to the fact that the manual strength of workers is large or the grinding angle is not well controlled, and finally waste is caused.

The effect of jacking piece lies in, if the aluminium alloy props up the plane of pad on the brace table great, cylinder B jacking compresses tightly the section bar plane between jacking piece up end and splint lower extreme face, prevents that the aluminium alloy from shifting. The jacking block moves upwards to the highest point, the upper plane of the jacking block is level to the upper plane of the support table, then the large plane of the section bar is placed upwards on the plane formed by the jacking block and the support block, and then the two cylinders A drive the clamping plates to clamp the section bar for chamfering and milling the end of the large plane of the section bar; the jacking block moves downwards to the lowest point, enough space is vacated in the middle of the supporting table, at the moment, the inclined plane of the section bar can be placed upwards on the plane of the jacking block, and then the two cylinders A drive the clamping plates to clamp the section bar, so that the chamfer angle milling of the end of the inclined plane of the section bar is carried out.

And the lower end surface of the clamping plate and the contact surface of the aluminum profile are provided with copying clamping pads. The profiling clamp pad is matched and attached to the upper surface of the aluminum profile, and more supports are given to the aluminum profile when the aluminum profile is chamfered and milled, so that the aluminum profile is stable and does not vibrate.

The upper end face of the jacking block is provided with a plurality of vertical positioning grooves. The vertical positioning groove has the following effects: the side edge of the positioning groove is tightly attached to the side edge of the aluminum profile, so that the position of the aluminum profile is completely vertical to the straight line of the milling advancing direction.

And two end parts of the slide rail are provided with limiting blocks. The sliding platform can be prevented from falling off the track.

The processing method of the utility model comprises the following steps:

(1) Selecting a supporting table and a profiling clamp pad which are matched in shape, and presetting whether the jacking block is used or not;

(2) Opening the angle grinder, rotating the milling cutter, placing the aluminum profile into the space below the clamping plate, tightly pushing the head end of the aluminum profile against the limiting plate, and horizontally placing the surface to be milled on the upper end surface of the supporting table;

(3) The air cylinder A/the air cylinder B are respectively controlled by the foot switch, the clamping plate is pressed down, the jacking block rises, and the aluminum section is clamped;

(4) An operator manually slides the angle grinder along the slide rail, grinding is carried out on the aluminum profile through the edge of the end part of the aluminum profile, then the air cylinder is loosened, the aluminum profile is drawn out, and the angle grinder is returned;

(5) Changing the surface of the aluminum profile, horizontally placing the surface to be milled on the upper end surface of the support table, grinding the edge chamfer of the other plane, and repeating the operation steps of the steps (1) - (3);

(6) Turning the direction of the aluminum profile, and repeating the operation steps from the step (1) to the step (4);

the invention has the advantages that:

1. the utility model discloses can realize the processing operation that complicated section aluminium alloy terminal surface chamfer milled, greatly improve the efficiency of complicated section aluminium alloy terminal surface chamfer processing, reduce workman's working strength, avoid because the difference of workman's operation proficiency, and lead to the change of chamfer size quality, improve the stability of processing production, reduce the disqualification rate of production.
