Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of support frame equipment, in particular to a support frame structure for rolls that is convenient to adjust. Background Art
[0002] A roll is the main working part and tool on a rolling mill that causes continuous plastic deformation of metal. A roll mainly consists of three parts: a roll body, roll necks, and shaft heads. The roll body is the middle part of the roll that actually participates in rolling metal. It has a smooth cylindrical or grooved surface. The roll necks are installed in bearings, and the rolling force is transmitted to the rolling mill stand through the bearing seats and screw-down devices. The drive-end shaft head is connected to the gear housing through a coupling shaft to transmit the rotational torque of the motor to the roll. The rolls can be arranged in the form of two-high, three-high, four-high, or multi-high in the rolling mill stand.
[0003] During transportation, a roll support is generally used to support the roll. However, the sizes of roll supports are fixed, and different models of roll supports can only be used for rolls of different sizes, resulting in higher costs. Summary of the Utility Model

Detailed implementation manners
[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0027] Based on this, the technical problem in the related art that the same support cannot fix rolling mills of different sizes can be improved. The embodiments of the present application provide the following solutions.
[0028] Please refer to Figures 1 to 3 together. The embodiments of the present application provide a support frame structure for a rolling mill roll that is easy to adjust, including a frame 10 and a plurality of fixed structures 20;
[0029] The frame 10 includes a base 11, a plurality of top plates 12, a plurality of bottom plates 13 and a plurality of support rods 14. The top plates 12 and the bottom plates 13 are fixedly arranged between the plurality of support rods 14, and both ends of the base 11 are arranged on the bottom plates 13;
[0030] The fixing structure 20 includes a cylinder 21, a connecting block 22 and a plurality of pressing plates 23. The cylinder 21 is arranged on the top plate 12. The output end of the cylinder 21 penetrates through the top plate 12 and is connected to the connecting block 22. One ends of the plurality of pressing plates 23 are symmetrically and fixedly arranged on the side walls on both sides of the connecting block 22, and the other ends are slidably mounted on the support rod 14. The pressing plates 23 are inclined downward in a direction away from the connecting block 22.
[0031] As can be seen from the above, when fixing the roll, first place the roll on the base 11, start the cylinder 21, move the connecting block 22 downward, drive the two pressing plates 23 on the connecting block 22 to move downward until they abut against the side wall of the roll. The two ends of the roll are clamped between the two pressing plates 23 and the base 11 to form a fixation. The two ends of the roll are clamped between the two pressing plates 23 and the base 11, and the pressing plates 23 can move up and down, so that the two pressing plates 23 and the base 11 can clamp and fix rolls of different sizes, solving the technical problem that the same bracket cannot fix rolls of different sizes.
[0032] Optionally, in some embodiments, please refer to Figures 1 to 3 , a backing plate 24 is arranged on the side wall of the pressing plate 23 close to the base 11.
[0033] With such a setting, the backing plate 24 is elastic. After the roll is placed on the base 11, the connecting block 22 is moved downward, driving the two pressing plates 23 on the connecting block 22 to move downward until the roll abuts against the side wall backing plate 24. The two ends of the roll are clamped between the two pressing plates 23 and the base 11 to form a fixation. The backing plate 24 is used to form a buffer between the pressing plate 23 and the roll, and is used to reduce the probability of abrasion of the roll when the pressure of the pressing plate 23 is too large.
[0034] Optionally, in some embodiments, please refer to Figure 3 , a plurality of screw rods 241 are arranged on the backing plate 24. One end of the screw rod 241 is rotatably connected to the pressing plate 23, and the other end passes through the backing plate 24 and is connected with a knob 242.
[0035] With such a setting, the backing plate 24 can be detachably mounted on the pressing plate 23 through the screw rod 241, which is convenient for replacement. The knob 242 is used to facilitate the staff to control the rotation of the screw rod 241.
[0036] Optionally, in some embodiments, please refer to Figure 3 , the plurality of screw rods 241 are distributed at the four peripheral edges of the backing plate 24. A groove 243 is formed on the backing plate 24, and the knob 242 is located in the groove 243.
[0037] With such a setting, the arrangement of the distribution position of the screw rod 241 is used to reduce the probability that the screw rod 241 abuts against the roll and is damaged during the process of the pressing plate 23 moving downward and pressing the roll.
[0038] Optionally, in some embodiments, refer to Figure 1 , an arc-shaped notch 111 is formed on the base 11, and the arc-shaped notch 111 extends along the length direction of the base 11.
[0039] With such a setting, when a roll is placed on the base 11, the roll will move to the bottom of the arc-shaped notch 111 under the action of gravity, which is convenient for positioning and subsequent clamping and fixing operations.
[0040] Optionally, in some embodiments, refer to Figures 1 to 2 , a limiting rod 231 is provided on the pressing plate 23, a limiting groove 121 is formed on the top plate 12, and the limiting rod 231 is slidably attached to the inner wall of the limiting groove 121.
[0041] With such a setting, during the downward movement of the pressing plate 23, the limiting rod 231 is slidably installed on the top plate 12 through the limiting groove 121, so that the pressing plate 23 is difficult to shake during the movement.
[0042] Optionally, in some embodiments, refer to Figures 1 to 2 , a sliding strip 141 is provided on the support rod 14, a sliding groove 232 is formed on the pressing plate 23, and the sliding groove 232 is slidably attached to the inner wall of the sliding strip 141.
[0043] With such a setting, during the downward movement of the pressing plate 23, the sliding groove 232 is slidably attached to the inner wall of the sliding strip 141, so that the lower end of the pressing plate 23 is difficult to shake during the movement, and after the roll is fixed, the lower end of the pressing plate 23 abuts against the sliding strip 141 and is difficult to shift, improving the fixing effect of the pressing plate 23.
[0044] Optionally, in some embodiments, refer to Figure 1 , a through hole 131 is formed on the bottom plate 13 for a part of the pressing plate 23 to pass through.
[0045] With such a setting, the downward movement range of the pressing plate 23 is increased, so that rolls with smaller sizes can also be clamped and fixed between the two pressing plates 23 and the base 11.
[0046] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
