Description

Technical Field

[0001] The invention relates to mechanical processing technology, and more specifically to a processing method for a special-shaped port of an I-beam of a cable track. Background Art

[0002] Cables are used to provide power to the quay cranes. Therefore, they must not affect the operation of the quay cranes when they are laid on the quay cranes. The cables must be laid out in a reasonable direction by laying cable tracks. The cable tracks are made of I-beams. During preparation, the joints of the front and rear beams between the two I-beams are always marked on site and then flame cut and polished. However, this method makes it impossible to guarantee the quality and accuracy of the cable tracks, especially the weld gaps at the joints are difficult to meet the design requirements. Summary of the invention

[0003] In view of the above-mentioned defects existing in the prior art, the purpose of the present invention is to provide a method for processing the special-shaped ports of I-beams of cable tracks, which adopts a method of combining multiple machine tools and equidistant scribing processes to process the special-shaped interface ends, thereby solving the problem that the quality and precision of existing cable tracks cannot be guaranteed.

[0004] To achieve the above object, the present invention adopts the following technical solution:

[0005] A method for processing a cable track I-beam special-shaped port comprises the following steps:

[0006] S1. Apply light gold water to the parts of the surfaces of the two I-beams that need to be marked;

[0007] S2, placing the two I-beams vertically, and marking a vertical neutral plane circumference line on the outer circumference of the I-beams as a marking reference line;

[0008] S3, placing the two I-beams horizontally, parallel and side by side, and drawing a center line on the top surface, bottom surface and waist portion, as well as cross-sectional lines on both sides of the center line;

[0009] S4. Draw the joint lines of the top surface, bottom surface and waist width on one side of the vertical neutral plane circumference of the two I-beams, and punch the lines;

[0010] S5, placing the two I-beams horizontally in a line, and after the circumference of the vertical neutral plane is equidistant, check whether the corresponding points of the joint line are equidistant;

[0011] S6. After the corresponding points of the joint line are equidistant, first process the joint surface of the waist portion according to the sample punching line, and then process the joint surfaces of the top and bottom surfaces.

[0012] Preferably, the I-beam is placed on a marking platform and has a length between 0.9 and 1.1 m.

[0013] Preferably, in step S2, a marking height ruler is used to mark the circumference of the vertical neutral plane;

[0014] The vertical neutral plane circumference is 50±0.5 mm away from the bottom end of the I-beam.

[0015] Preferably, in step S3, the cross-section line is 80±0.5 mm away from the center plane line.

[0016] Preferably, in step S6, an electric spark wire cutting machine is used to process the joint surface of the waist width portion;

[0017] The joint surfaces of the top and bottom surfaces are processed by an end mill.

[0018] The present invention provides a method for processing a special-shaped port of an I-beam of a cable track, which has the following beneficial effects:

[0019] 1) A new idea for the processing and manufacturing of interfaces (heads) is provided, namely, virtual datum parallel separation technology. When marking, a virtual datum (perpendicular to the circumference of the neutral plane) is set, and then it is parallelly divided at different positions to achieve a perfect composite replication effect. The method is simple and easy to implement;

[0020] 2) Line processing can be implemented at any segment (end), which greatly simplifies the difficulty of manufacturing and processing, making the impossible possible;

[0021] 3) The new idea of ​​virtual benchmark parallel separation is not only applicable to the production and docking of special-shaped ports of cable track I-beams, but can also be extended to the production, detection, verification, calibration, and review of any docking ports.

[0029] Combination Figures 1 to 6 As shown, a method for processing a cable track I-beam special-shaped port provided by the present invention comprises the following steps:

[0030] S1. Arrange a pair of 1m long I-beams on the marking platform, and apply light gold water on the top, bottom and waist parts to be marked;

[0031] S2. Place two track I-beams vertically on the marking platform, adjust them to a vertical state, and use a marking height gauge to mark the vertical neutral plane circumference 1 of the outer circumference of the track I-beam at a distance of 50 mm as the marking reference plane line;

[0032] S3. Lay down two rail I-beams, parallel and side by side, and use a marking height gauge to mark the center surface lines 2, 3, and 4 of the top surface, bottom surface and waist width respectively. Then use a marking height gauge to mark the cross-section line 5 of the top surface, bottom surface and waist width at a distance of plus or minus 80 mm (symmetrical to the center surface line);

[0033] S4. Make the top surface, bottom surface and waist joint lines 6, 7, 8 of the two track I-beams near the vertical neutral plane circumference 1 of the two track I-beams according to the requirements of the drawings and punch them;

[0034] S5. Place the two 1m long I-beams marked on the marking platform in a row, and check whether the corresponding points 9 of the joint lines are equidistant after ensuring that the vertical neutral plane circumference 1 is equidistant;

[0035] After S6 and the corresponding points 9 of the joint lines are equidistant, punch the lines according to the sample (joint lines 6, 7, 8, retain half of the sample punching holes), first use the EDM wire cutting machine to calibrate and process the waist joint surface, and then use the vertical milling machine to calibrate and process the top and bottom joint surfaces. After roughening and chamfering, match them, knock the steel stamp, and sand punch them into the warehouse for project use.
