Description

Technical Field

[0001] The utility model belongs to the field of steel rolling mills, and more specifically relates to a guide groove device capable of adjusting the center line alignment of steel materials. Background Art

[0002] The production range of large-size round steel is relatively large, generally between φ70-φ260, center line 35-130mm, and the center line distance is nearly 100mm. During the steel rolling production process, this brings great difficulties to the movement of steel and diameter measurement. During the movement of steel, small-size round steel will swing left and right because the center line is much lower than the rolling center line, which is very easy to cause bending and scratching. In addition, the height of the equipment cannot be adjusted, resulting in a large deviation in the center line of the steel, which cannot meet the steel measurement requirements and ensure that the center line of the steel remains basically unchanged. In this way, the measurement cannot be completed and the test results cannot be guaranteed to be accurate, so the use of online measurement equipment cannot be realized.

[0003] The existing solution is to raise the height of small-sized guide grooves by manually adding pads, but there are steps in adjusting the height, which cannot achieve continuous and accurate adjustment. In addition, the adjustment is difficult, time-consuming and labor-intensive, and it is basically difficult to achieve the requirements of online measurement. At the same time, the height and width adjustment are not appropriate, which can easily cause bent steel and scratches. Utility Model Content

The guide groove device can adjust the height of the guide groove mechanism through a lifting structure to achieve adjustment of the center line, thereby ensuring the normal use of online measuring equipment. In addition, the width of the guide groove mechanism can be adjusted by adjusting bolts to avoid bending and scratching of steel materials.

DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0035] The utility model provides a guide groove device capable of adjusting the center line alignment of steel materials, comprising:

[0036] The roller table has a lifting mechanism disposed on the top, the lifting mechanism includes a turntable, when the turntable is rotated, the output end of the lifting mechanism is displaced in the height direction;

[0037] The guide groove mechanism is arranged on the output end of the lifting mechanism. The guide groove mechanism comprises a frame and two lateral limit blocks. The frame is threaded with adjustment bolts arranged corresponding to the lateral limit blocks. The ends of the adjustment bolts abut against the lateral limit blocks.

[0038] Specifically, a lifting mechanism and a guide groove mechanism are provided in the guide groove device. The lifting mechanism can adjust the height of the guide groove mechanism. In addition, the spacing between the two lateral limit blocks can be changed in the guide groove mechanism by screwing the adjustment bolt. In this way, the height and width of the guide groove can be adjusted according to the diameter and center line position of the steel, thereby avoiding bending and scratching of the steel during movement and enabling the online measuring equipment to be used normally.

[0039] Optionally, the roller frame includes two first steel sections parallel to each other, and extended supports are respectively provided on the sides of the first steel sections away from each other, and the extended supports are vertically welded to the first steel sections.

[0040] Specifically, the roller frame is composed of two first steel sections arranged in parallel, and an extended support is vertically welded on the outer side of the first steel section, which can ensure that the guide groove mechanism is placed more stably, and the lifting mechanism can be reasonably arranged on the roller frame to ensure that the height of the lifting mechanism can be changed when the turntable is rotated.

[0041] Optionally, the lifting mechanism comprises:

[0042] A gear box, with a rotating disc disposed on the input end;

[0043] A screw rod, one end of which is connected to the output end of the gear box, and a screw nut is movably provided on the screw rod;

[0044] Camshaft, the shaft rod of the camshaft is connected with the nut through a connecting frame, and the cam of the camshaft fits under the guide groove mechanism.

[0045] Specifically, a gearbox is provided in the lifting mechanism, and a worm gear is provided in the gearbox. The worm gear rotates on the side plane of the guide groove device, and the worm gear rotates on the end plane of the guide groove device. The turntable rotates synchronously with the worm gear, so that the screw and the worm gear can be driven to rotate synchronously. Under the rotation of the screw, the nut moves along the axial direction of the screw. Since the nut is hingedly connected to the connecting frame, and the connecting frame is also hingedly connected to the camshaft, the movement of the nut can drive the rotation of the camshaft. When the convex surface of the cam of the camshaft contacts the bottom of the guide groove mechanism, the height of the guide groove mechanism will increase. When the circular surface of the cam of the camshaft contacts the bottom of the guide groove mechanism, the height of the guide groove mechanism will decrease. In addition, the outer surface of the camshaft is always in contact with the bottom of the guide groove mechanism. In this way, the height of the guide groove mechanism changes slowly with the different contact positions with the camshaft. The height adjustment of the guide groove mechanism is more precise, and there will be no step-by-step height adjustment.

[0046] Optionally, the connecting frame includes two connecting plates parallel to each other, one end of the connecting plate is rotatably arranged on the shaft of the camshaft, and the other end of the connecting plate is rotatably matched with the outer periphery of the nut.

[0047] Specifically, two connecting plates are arranged between the shaft rod of the camshaft and the nut. The two connecting plates clamp and connect the nut from both sides. Bearings are arranged on the outer periphery of the nut and the connecting plates. When the nut rotates, the connecting plates will not be linked. Only when the nut moves axially along the screw rod can the nut drive the end of the connecting plate to rotate. In this way, the connecting plate can also drive the shaft rod of the camshaft to rotate, thereby changing the contact position of the cam of the camshaft and the guide groove mechanism.

[0048] Optionally, the gear box is arranged on an extended support, and the first steel section is connected to the camshaft via a rotating support.

[0049] Specifically, in the lifting mechanism, the gearbox is arranged on the extended support, and the camshaft is arranged on the first steel section through the rotating support, so that the power part of the lifting mechanism is located outside the first steel section and the guide groove mechanism, the turntable, the gearbox and the screw belong to the power part, and the torque generated by the power part causes the height of the guide groove mechanism to change, and the output part of the lifting mechanism is located inside the two first steel sections and below the guide groove mechanism, and the cam of the camshaft belongs to the output part, and the height change of the guide groove mechanism is directly affected by the rotation of the cam. When the power part fails, other methods can be used to drive the cam of the camshaft to rotate, which will not affect the normal lifting and lowering of the guide groove mechanism, and repairing the power part will not affect the normal use of the guide groove device.

[0050] Optionally, at least two camshafts are arranged below the guide groove mechanism, and a linkage rod is arranged between the multiple camshafts.

[0051] Specifically, multiple camshafts are evenly arranged below the guide groove mechanism, which can make the guide groove mechanism rise and fall more smoothly, and linkage rods are arranged between the camshafts, which can reduce the number of turntables, gear boxes and screw rods, and simplify the structure of the guide groove device.

[0052] Optionally, the guide groove mechanism comprises:

[0053] Two second steel sections connected to the output ends of the lifting mechanism;

[0054] A plurality of support frames, the bottom of which is connected to the second steel section, ground rollers are arranged between adjacent support frames, and lateral limit blocks are arranged on the top of the support frames;

[0055] The side support roller is arranged on the side where the lateral limit blocks are close to each other.

[0056] Specifically, in the guide groove mechanism, a frame is formed by welding the second steel section and the support frame. The position of the second steel section corresponds to the cam of the camshaft, and the support frame and the second steel section are perpendicular to each other. The ground roller is arranged between the support frames, and the upper surface of the ground roller is higher than the upper surface of the support frame, so that when the steel passes through the guide groove mechanism, the ground roller can roll and fit with the steel to ensure that the steel is stably supported; two lateral limit blocks are movably arranged above the support frame, and a channel for the steel to move is formed between the lateral limit blocks, and side support rollers are protruding on the inner side of the lateral limit blocks, so that the side support rollers can ensure that the steel passes smoothly, and the side support rollers are used to position the steel surface to avoid bending of the steel.

[0057] Optionally, brackets are respectively provided at the ends of the support frame, and the adjustment bolts are screwed on the brackets.

[0058] Specifically, a bracket is arranged on the support frame, and adjusting bolts are respectively screwed on the brackets on both sides of the same support frame. By screwing the adjusting bolts, the lateral limit blocks can be pushed inward to adjust the width of the steel travel channel.

[0059] Optionally, a guide groove is provided on the lateral limit block, and a guide rod penetrating the guide groove is provided on the support frame.

[0060] Specifically, in order to ensure the accuracy of the moving direction of the lateral limit block, an oblong guide groove is opened on the lateral limit block, and a guide rod is also provided on the support frame below the lateral limit block. In this way, after the adjustment bolt is screwed, the movement direction of the lateral limit block will be restricted by the guide rod, ensuring that the two lateral limit blocks are always in a parallel state to each other, avoiding the lateral limit block from rotating due to inconsistent extension lengths of the adjustment bolts, causing bending of the steel after passing through.

[0061] Optionally, a bearing seat is provided on the second steel section, and the bearing seat is connected to the ground roller.

[0062] Specifically, the bearing seat can ensure that the ground roller can rotate at the speed of the steel material, and the steel material and the ground roller will not be scratched.
