Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of template detection, and particularly relates to a detection table for a pass template of a section steel roll. Background Art
[0002] Generally, the accuracy requirements for the pass of a section steel BD roll (blooming stand roll) are relatively high, and numerical control lathes are required for processing. Considering factors such as programming errors, unreasonable tool selection, and tool compensation deviations in numerical control machining, they will affect the pass deviation of the BD roll. During the process of processing the pass of the section steel BD roll and inspecting the finished product, a pass template is generally used for detection. Section steels include angle steels, channel steels, H-beams, hat steels, and other various special-shaped steels, with a wide variety of types. For each specification of the roll pass, a corresponding template of this specification needs to be matched.
[0003] The BD roll template is generally made of a steel plate with a thickness of 1 mm to 3 mm according to the size of the profile pass, and is processed by means of numerical control machine tool cutting such as wire cutting, laser cutting (numerical control milling can also be used). Due to the existence of the wire diameter of wire cutting and the melting gap of laser cutting, for the pass template cut according to the theoretical dimensions of the pass drawing, the convex (male template) roll pass template will be smaller than the theoretical dimensions, and the concave (female template) roll pass template will be larger than the theoretical dimensions. The existing methods for solving the influence caused by the wire cutting wire gap and the laser cutting melting gap in template production generally involve compensation through numerical control cutting programs to ensure that the actual dimensions are the same (or similar) to the theoretical dimensions.
[0004] The BD roll template is a special-shaped non-standard part, and the pass of some section steels is even more complex. Whether the template produced through compensation can meet the actual usage compliance needs to be further detected. However, the existing detection equipment cannot effectively detect complex special-shaped templates, which will greatly affect the accuracy of subsequent detection of the pass of the section steel BD roll.

[0036] The inspection plate 1 is set as a cuboid, the upper surface of the inspection plate 1 is set as a horizontal plane, and the lower surface of the inspection plate 1 is connected to the support frame 2.
[0037] As Figure 3 shown, Figure 3 is the structural top view of the support frame; the support frame 2 includes a support frame 21 and support rods 22. The support frame 21 is fixedly supported on the ground through the support rods 22. The support frame 21 includes two long rods and two short rods.

A vertically arranged adjustment bolt is threadedly connected inside the adjustment nut. The upper end of the adjustment bolt is in contact with the lower surface of the inspection plate 1. By adjusting the relative positions of the adjustment bolt and the adjustment nut, the leveling operation of the upper surface of the inspection plate 1 can be realized to ensure that the upper surface of the inspection plate 1 is in a horizontal state.
[0038] As Figure 4 andFigure 5 As shown Figure 4 is the front view of the structure of the bottom plate; Figure 5 is the top view of the structure of the bottom plate. The bottom plate 3 is set as a cuboid plate member. The first detection surface 31 and the first fitting surface 35 of the bottom plate 3 are arranged on both sides of the back surface 32 of the bottom plate 3. The first fitting surface 35 and the first detection surface 31 are arranged in parallel. The first fitting surface 35 is fitted with the upper surface of the detection plate 1.

[0044] Generally, the second fixing groove extends linearly from the second detection surface 41 to the second fitting surface, and the second fixing grooves are arranged equidistantly and in parallel, so that the fixing position between the second fixing bolt and the section steel roll pass template 5 can be adjusted according to the actual situation.
[0045] Preferably, a plurality of fixing holes are provided on the section steel roll pass template 5, and the first fixing bolt 34 or the second fixing bolt is arranged in one-to-one correspondence with the fixing holes. By passing the first fixing bolt 34 or the second fixing bolt through the corresponding fixing holes and tightening the corresponding first fixing nut or second fixing nut against the section steel roll pass template 5, the fitting setting of the section steel roll pass template 5 with the backrest surface 32 or the third fitting surface is realized.

[0047] It should be noted that between the bottom plate 3 and the detection plate 1, between the bottom plate 3 and the adjacent adding plate 4, and between two adjacent adding plates 4, detachable fixed connections can be realized through conventional connection and limiting structures, such as bolt connection, clamping, etc., to ensure the relative position stability.
[0048] Embodiment III
[0049] As Figure 7 , Figure 8 , Figure 9 shown, Figure 7 is the schematic diagram of the step S2; Figure 8 is the schematic diagram of the step S3; Figure 9 is the schematic diagram of the step S4.
[0050] The detection method of the detection table of the section steel roll pass template of the present invention includes the steps:
[0051] S1. After placing the bottom plate 3 on the upper surface of the detection plate 1, the reference surface of the section steel roll pass template 5 to be detected is arranged in contact with the upper surface of the detection plate 1, and the surface of the section steel roll pass template 5 is fixedly attached to the back surface 32 of the bottom plate 3 through the first fixing bolt 34;
[0052] S2. Press the jaw plane of the vernier caliper tightly against the first detection surface 31 of the bottom plate 3, and measure the actual dimension L1 of the width of the first measurement part of the section steel roll pass template 5 on the plane where the first detection surface 31 is located;
[0053] S3. Add one more adding plate 4 above the bottom plate 3, press the jaw plane of the vernier caliper tightly against the second detection surface 41 of the adding plate 4, and measure the actual dimension L2 of the width of the second measurement part of the section steel roll pass template 5 on the plane where the second detection surface 41 is located;
[0054] S4. Based on the thickness of the bottom plate 3, set the first height horizontal line 6 on the design drawing, and based on the thickness dimension of the adding plate 4, set the second height horizontal line 7. Both the first height horizontal line 6 and the second height horizontal line 7 intersect with the template pass line on the design drawing at two intersection points. Obtain the distance between the two intersection points corresponding to the first height horizontal line 6, which is the theoretical dimension L1' of the width of the first measurement part, and the distance between the two intersection points corresponding to the second height horizontal line 7, which is the theoretical dimension L2' of the width of the second measurement part;
[0055] S5. Compare the actual dimension L1 of the width of the first measurement part with the theoretical dimension L1' of the width of the first measurement part, and compare the actual dimension L2 of the width of the second measurement part with the theoretical dimension L2' of the width of the second measurement part. When the deviation between L1 and L1', and between L2 and L2' is less than 0.1 mm, and the deviation directions are the same (either both + or both -), the pass template is qualified. When the deviation between L1 and L1', and between L2 and L2' is greater than 0.1 mm, or the deviation directions are opposite, and the difference between + and - is greater than 0.1 mm, the pass template is unqualified.
[0056] Preferably, the step S3 can be repeated, and by setting multiple adding plates 4 to measure the actual dimensions at multiple heights, multiple groups of actual dimensions and theoretical dimensions can be compared to improve the detection accuracy.
[0057] Example 4
[0058] This example is an actual use example. In this example, the section steel roll pass is as Figure 10 shown, and the section steel roll pass template is as Figure 11As shown, an extension plate is added to the pass template 5 of the section steel roll on the basis of the pass of the section steel roll, which is convenient for the operator to hold.
[0059] The size of the inspection plate 1 is designed to meet the requirements of the template for the size of the BD roll pass. In this embodiment, the pass of the section steel roll is nearly 800 mm, which is relatively large. Therefore, the size of the designed inspection plate 1 is 800 mm * 400 mm * 100 mm.
[0060] The inspection plate 1 mainly serves as a reference surface for placing the template. Therefore, the inspection plate 1 should meet the quality requirements of flatness and surface roughness. To meet the straightness requirement within the length range of the 800 mm template, the flatness tolerance of the upper surface of the inspection plate 1 is designed to be 0.015 mm. Correspondingly, the surface roughness of the upper surface of the inspection plate 1 is designed to be Ra1.6. To ensure the flatness and roughness requirements, the upper surface of the inspection plate 1 should be ground in the final process. At the same time, considering the influence of machining deformation and long-term use deformation, materials with small deformation amounts should be selected for the inspection plate 1, such as HT200 and other materials. Considering the long-term use deformation and wear of the inspection plate 1, the upper surface of the inspection plate 1 can be ground and repaired regularly. Considering the problem of repair and hoisting of the inspection plate 1, 2 M16 threaded holes are designed on the upper surface of the inspection plate 1 for installing a lifting hook.
[0061] The support frame 2 supports and fixes the inspection plate 1 and is made by welding with angle steel, etc. The inner cavity size of the support frame 2 is 800 mm * 400 mm, which has a clearance fit with the outer shape size of the inspection plate 1. The height of the support frame 2 is made according to the habitual needs of the measuring personnel, generally about 800 mm. The support frame 2 is designed as the height of the 700 mm support frame 2 + the thickness of the inspection plate 1 of 100 mm = 800 mm. Considering that the support horizontal plane made of angle steel may not meet the horizontal requirement of the platform support frame 2 in extreme cases, 2 holes are drilled on each of the 2 sides of 800 mm of the support frame 2, and nuts are welded on the holes, so that the inspection platform can be adjusted.
[0062] The production of the backrest plate and the additional plate 4 serves as a support and fixation for the template. The sizes of the backrest plate and the additional plate 4 should also meet the requirements of the BD roll pass type and the ability to be stacked. According to the BD roll pass type requirements and the template inspection requirements, each template should have at least 2 inspection points, or three types of template backrests with different height specifications should be made according to the size of the pass template for stacking use. That is, three types: 800*100*50mm, 800*100*100mm, and 800*100*200mm. The available inspection heights are 50mm, 100mm, 150mm (100 + 50), 200mm, 250mm (200 + 50), 300mm (200 + 100), 350mm (200 + 100 + 50), etc., a total of 7 inspection points.
[0063] The first fitting surface 35 is placed on the inspection plate 1 and is also the reference surface of the backrest plate and the additional plate 4. To reduce measurement errors, it is required that the flatness error of the first fitting surface 35 is less than 0.015mm.
[0064] The first inspection surface 31 and the second inspection surface 41 are the reference surfaces for vernier caliper measurement and, at the same time, are the reference surfaces for stacking another additional plate 4. Therefore, the first inspection surface 31 and the second inspection surface 41 must first meet the requirement that the flatness error is less than 0.015mm, and secondly, they must also meet the parallelism requirement of 0.02mm between the upper and lower planes.
[0065] The back surface 32 of the backrest is used to support and fix the template. 16 T-shaped grooves with a size of 20mm * 14mm are machined on the back surface 32 (depending on the shape of the template). The template is closely attached to the back surface 32, and a T-shaped nut screwed into the T-shaped groove is used to press the pressing plate 36 to fix the template on the back surface 32. To meet the accuracy requirements of template inspection, the flatness error of the back surface 32 is less than 0.015mm, and the perpendicularity relative to the first fitting surface 35 is less than 0.03mm.
[0066] The above is only the preferred embodiment of the present invention, which is illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
