Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel rolling mill equipment, and in particular relates to a combined guide device for an H-shaped steel universal rolling mill. Background Art
[0002] At present, hot-rolled H-beam products are widely used in various fields of the national economy. Due to the wide variety of varieties and specifications, the guides and guards for universal rolling mills are mostly similar in shape, with only different widths. A production line generally covers a product width of about 200-400mm. Small production lines cover 100-300; medium-sized production lines cover 300-600; large production lines cover 600-1000. Each production line has as many as 20-40 product series. Two sets of guides and guards are prepared for each specification, resulting in a large reserve of rolling mill guide and guard spare parts and a large amount of capital occupation. Utility Model Content
[0003] The utility model aims to solve the above problems and provides a combined guide device for an H-beam universal rolling mill.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0005] A combined guide device for an H-beam universal rolling mill comprises a plurality of guide units, wherein the plurality of guide units are connected to the rollers alternately end to end;
[0006] The guide unit includes two upper and lower guide templates, several groups of adjustment plates, several groups of fastening bolts, four fixed plates and two clamping plates, each group of adjustment plates includes four adjustment plates, each group of fastening bolts includes twelve fastening bolts, the clamping plates are respectively arranged at the lower end of the upper guide template and the upper end of the lower guide template, and the four adjustment plates and four fixed plates are respectively arranged at the two ends of the two clamping plates through fastening bolts.
[0007] Furthermore, the thicknesses of the plurality of adjustment plates are different, and the lengths of the plurality of fastening bolts are different.
[0008] Furthermore, the thickness of each set of adjustment plates matches the width H of the H-shaped steel, and the length of each set of fastening bolts matches the thickness of the adjustment plates.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] 1. The utility model is easy to disassemble and assemble, and has many shared parts. After use, the weight of the guide and guard reserve will be greatly reduced, and the guide and guard consumption and the capital occupation of guide and guard spare parts will be greatly reduced;
[0011] 2. The utility model has a simple structure, low production cost and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] like Figure 1-5 As shown, a combined guide device for an H-beam universal rolling mill includes a plurality of guide units, wherein the plurality of guide units are connected to the rollers 7 alternately end to end;
[0020] The guide unit includes two upper and lower guide templates 1, several groups of adjustment plates 2, several groups of fastening bolts 3, four fixed plates 4 and two clamps 6. The thickness of the several groups of adjustment plates 2 is different. Each group of adjustment plates 2 includes four adjustment plates 2. The thickness of each group of adjustment plates 2 matches the width H of the H-shaped steel 5. The lengths of the several groups of fastening bolts 3 are different. Each group of fastening bolts 3 includes twelve fastening bolts. The length of each group of fastening bolts 3 matches the thickness of the adjustment plate 2. The clamps 6 are respectively arranged at the lower end of the upper guide template 1 and the upper end of the lower guide template 1. The four adjustment plates 2 and the four fixed plates 4 are respectively arranged at the two ends of the two clamps 6 through the fastening bolts 3.
[0021] The working process of this utility model:
[0022] When the utility model is used, firstly, the adjusting plate 2 matching the thickness B is selected according to the width H of the H-shaped steel, and then the fastening bolts 3 matching the thickness of the adjusting plate 2 are selected, and the four adjusting plates 2 and the fixing plate 4 of this group are fixed to the two ends of the two clamping plates 6 by the fastening bolts 3. When fastening, do not tighten them all at once. After the fastening bolts 3 are tightened, adjust the various parts of the guide to be flush, and then tighten the fastening bolts 3. Finally, start the rolling mill. After the H-shaped steel enters the guide device, the web is located between the two clamping plates 6, and the wing plates are located at the two ends of the clamping plates 6. The H-shaped steel can just move forward along the guide device.
[0023] When the specification of the H-beam changes, just remove the fastening bolts 3, take down the adjustment plate 2 and the clamping plate 6, then select the adjustment plate 2 with the appropriate thickness and the fastening bolts 3 with the appropriate length, repeat the above steps, and install them.
