Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, a guide device of a hot rolled bar pinch roll comprises two guide clamping plates 1, wherein the two guide clamping plates 1 are in mirror symmetry, a guide groove 2 is formed in one side of the guide clamping plate 1, a clamping groove 3 is formed in the other side of the guide clamping plate 1, one end of the guide clamping plate 1 is inclined, and two through pin holes 4 are formed in the guide clamping plate 1. One end of the guide groove 2 is square, the other end of the guide groove 2 is semicircular, one square end of the guide groove 2 is in a closing-in shape, the closing-in angle of one closing-in shape end of the guide groove 2 is 31 degrees, and one arc-shaped closing-in shape end of the guide groove 2 is smoothly transited to one semicircular end. When the guide clamp plate 1 is used, the bar 5 is clamped in the guide groove 2, and the diameter of one semicircular end of the guide groove 2 is 1mm larger than the diameter of the bar 5. The inclined angle of the inclined end of the guide clamping plate 1 is 22 degrees. The diameter of the pin hole 4 on either guide splint 1 is 1mm larger than the diameter of the pin hole 4 on the other guide splint 1. The pin holes 4 with larger diameters on the two guide clamping plates 1 are not concentric with the pin holes 4 with smaller diameters on the same side.
Taking bar 5 with the diameter of 26mm as an example, the width of one square end of the guide groove 2 is 60mm, the diameter of one semicircular end after closing in is 27mm, the diameter of the pin hole 4 on any guide clamping plate 1 is 10mm, and the diameter of the pin hole 4 on the other guide clamping plate 1 is 11mm.
The working principle of the utility model is as follows: as shown in fig. 1-5, when in use, two guide clamping plates 1 are matched and then inserted into the positioning pins of the guide Wei Gachi device 6 through the stud holes 4, the clamping device 6 clamps the guide Wei Gaban 1 through the clamping groove 3, one inclined end of the guide clamping plate 1 faces the pinch roll 7, and when in operation, a bar 5 enters from a square end of the guide clamping plate 1 and is output from a semicircular end, and one end of the guide clamping plate 1 is inclined, so that the bar can be better close to the pinch roll 7. Because the square one end of the guide slot 2 is in a closing-in shape and the arc smoothly transits to the other end, and meanwhile, the diameter of one semicircular end is larger than that of the bar 5, the abrasion of the guide clamping plate 1 can be effectively reduced.
