Problems solved by technology

Because the steel plate to be cut is relatively thin, the strip steel with a thickness of 2~4mm is mainly cut, the blade blade is slightly worn, and the effect of the cut steel plate is not ideal, so the blade needs to be replaced offline

Embodiment 1

[0029] The method for analyzing the data analysis of the fit gap between the double shear blades of the cold rolling welding machine described in this embodiment comprises the following steps:

[0030] S1. After the repair of the double shearing machine of the cold rolling welding machine is completed, the schematic diagram of the special inspection vertical lathe is placed. The assembled double shearing shearing machine of the cold rolling welding machine is placed on the special inspection vertical lathe. The frame is fixed on the tool holder of the vertical lathe by tooling. The purpose is to use the machining accuracy of the vertical lathe to ensure that the upper and lower tool holders are always vertical during the movement. In this way, the on-site use state of the double shear of the cold rolling welding machine is completely simulated, which ensures the authenticity of the final measurement results;

[0031] S2. Move the tool holder of the vertical lathe, and use a f...

Embodiment 2

[0047] Please see image 3 and Figure 4 , with image 3 It is the analysis table 2 of the data analysis of the clearance between the shear blades of the double-cutting shears. The data detected in this chart reflect that the clearance of the shear blades is too small; Figure 4 It is the analysis table 3 of the data analysis of the clearance between the shear blades of the double-cutting shears. The data detected in this chart reflect that the clearance of the shear blades is too large. The adjustment steps are the same as the adjustment method in Embodiment 1, and will not be repeated in this embodiment.

Embodiment 3

[0049] Please see Figure 5 , with Figure 5 It is the analysis table 4 of the data analysis of the gap between the double shear blade and the clearance. The data detected in this chart shows that there is a large jump between points, and the variation range exceeds the design specification by 3 times. There are four specific reasons: (1) There are high points or burrs between the mating surface of the knife body and the tool holder body that have not been cleaned; (2) The body of the knife holder is deformed; (3) There are burrs on the blade or the high points have not been cleaned. Clean it up; (4) The blade is damaged; (5) The bolts are not tightened according to the specified torque in the design. Treatment measures:

[0050] 1. Disassemble the cutter body for inspection. If there are high points and burrs, use an oil stone for grinding.

[0051]2. Grinding the deformed area (special CNC grinding machine) to meet the design requirements.

[0052] 3. Check the blade and...

Abstract

The invention provides a shear edge fit clearance detection data analysis method of a cold-rolling welder double-cut shear. The method comprises the following steps: S1, placing a completely assembledcold-rolling welder double-cut shear on a detection vertical lathe, fixing a lower knife rest on a rotating platform, and fixing an upper knife rest on the vertical lathe knife rest by utilizing tooling; S2, moving a vertical lathe knife rest, and detecting and recording the shear edge fit clearance of the double-cut shear by using a filler gauge; S3, converting the detected numerical value intoa size value needing to adjust, and quickly judging which side the size value needing to adjust is more reasonable by combining the knife edge fall; and S4, adjusting according to an analysis result,and re-checking and measuring after accomplishing the adjusting until reaching a requirement. By analyzing the detection data, the corresponding processing measure is adopted for the place failed to meeting the requirement, thereby reaching an effect of doing half work with double results.

Description

Technical field: [0001] The invention relates to a method for detecting data analysis of a matching clearance between double shears of a cold-rolling welding machine, and belongs to the technical field of automatic control. Background technique: [0002] The double shear of the cold rolling welding machine is one of the important equipment of cold rolling. Its function is to cut the head of the strip in the previous circle and the tail of the strip in the next circle, remove the hairy part, and then use the laser welding machine to The front and rear strip steel coils are welded into one. The quality of welding mainly depends on the quality of strip steel shearing, so the requirements for the assembly accuracy of double shearing are quite high. Since the steel plate to be cut is relatively thin, mainly strip steel with a thickness of 2~4mm, the blade blade is slightly worn, and the effect of the cut steel plate is not ideal, so the blade needs to be replaced offline. After...
