My company and henan university of technology of mechanical developed GCF - 2 U steel stents roll forming machine, repair in GC - 1 type, based on the user via extensively solicit opinions and Suggestions, trial, the research, development, and set the U shaped steel stents roll forming and repair at an organic whole, with reasonable design, reliable operation, high precision, high automation degree, fill the domestic blank.
A, molding:
At present, most of the coal production by U steel stents are according to the arch, using the principle of moulding machine with special design model, the forming process, existing low accuracy, low efficiency of using this method (vaulted stents, making the curvature radius and the string length by the operation experience and skill worker, thus error bigger), Labor intensity is high, the poor safety, using a series of faults roller machine manufacture vaulted stents, overcome by moulding faults, a series of principles, has the following advantages:
L, production efficiency,
2, high precision and curvature radius of any convenient adjustment,
3 and greatly reduce the labor intensity, the safety of operation.
This machine is suitable for 25u, 29u, 36U three U steel beam by conditioning and leg after making molding, after U steel bracket, technical indexes accord with the coal with U steel scalability stents manufacturing technology "MTl95-89 standards in all the requirements, the domestic leading technology of" side roller swing four roll bending theory ", rolled steel stents beam leg U roll forming towel and fixed the time, automatic forming.
Second, repair:
Using the U steel bracket to ground, most coal were abandoned in the idle, or when scrap pile up, or extremely individual, coal to repair, molding part r, using method is still using the principle of mould repair, inefficient, repair to U steel strength loss is too big, too, with repair precision skirt hem and so on a series of weakness.
Roll forming repair machine of U steel arch support can be repaired, molding, overcome the shortcomings of the existing mold repair, with a series of high efficiency, to repair the intensity of small losses U shaped steel, high precision, then after forming, without skirt hem, etc.
