Description

Technical Field

[0001] The utility model relates to the technical field of cold beds for rolling mills, and specifically relates to a pressing cold bed for bar rolling production. Background Art

[0002] The cold bed is one of the indispensable auxiliary equipment in small and medium-sized bar workshops. Its function is to convey and unload the bars cut into multiple lengths by flying shears after rolling by the rolling mill onto the cold bed racks for cooling, so that their temperature drops from 900 °C to 100 - 300 °C, and then the cold bed blanking device collects them into groups and sends them to the output roller table, and then the output roller table sends them to the cold shear to cut them into fixed-length finished products. The design quality and installation accuracy of the cold bed directly determine the final quality of the product.

[0003] The existing patent document with the publication number of CN220005419U discloses an energy-saving step-type cold bed, including: an equipment platform and a hot water tank. Both sides of the top of the equipment platform are installed with support frames. The cooling plates are installed on the tops of both sides of the support frames. A driving motor is installed on one side of the top of the equipment platform close to both support frames through a motor seat. The output shafts of both driving motors are installed with driving disks. The rear surfaces of both driving disks are installed with rotating shafts. Feed plates are installed on the outer surfaces of both rotating shafts through connecting frames. A hot water tank is installed on one side of the top of the equipment platform close to the support frame.

[0004] However, the above device has the following problems when in use; when the existing cold bed is in use, the size of the teeth on the toothed plate used to bear and drive the bars to move is generally constant.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Please refer to Figures 1 to 7 , a steel pressing cooling bed for bar rolling production, including a bed body 1. The bed body 1 is the basic part of the entire device, which provides stable support to ensure that the device will not shift or become unstable due to external forces during operation.

[0030] A mounting plate 2 is provided on the bed body 1, and a fixing plate 3 is fixedly mounted on the mounting plate 2. First limiting rods 4 are fixedly mounted on the fixing plate 3 at equal intervals and uniformly.

[0031] Preferably, a corresponding device (not shown in the figure) for the mounting plate 2 to move should be provided at the bottom of the bed body 1, so as to realize the transfer activity of the bar. The same as the existing device, it will not be elaborated here.

[0032] A moving plate 5 is slidably mounted on the fixing plate 3. Second limiting rods 6 are fixedly mounted on the moving plate 5 at equal intervals and uniformly. The fixing plate 3 serves as a sliding track for the moving plate 5 to ensure that the moving plate 5 can slide smoothly on the fixing plate 3 without deviating from the direction.

[0033] By moving the moving plate 5, the distance between the first limiting rod 4 and the corresponding second limiting rod 6 can be changed, so as to be applicable to the cooling and transfer activities of bars of different sizes.

[0034] A connecting block 15 is fixedly mounted on the moving plate 5, and a rack 7 is fixedly mounted through the mounting plate 2 by the connecting block 15.

[0035] A driving mechanism is provided at the bottom of the mounting plate 2. The driving mechanism is located below the mounting plate 2 and is used to provide power and control the moving distance of the moving plate 5.

[0036] The driving mechanism includes a fixing block 10. The fixing block 10 is fixedly mounted on the bottom of the mounting plate 2. A rotating shaft 12 is rotatably mounted on the fixing block 10. A driving gear 11 is fixedly mounted on the rotating shaft 12, and a handwheel 13 is fixedly mounted on the rotating shaft 12.

[0037] A limiting mechanism is provided inside the rotating shaft 12. The limiting mechanism is located inside the rotating shaft 12 and is used to lock the rotating shaft 12 to prevent it from rotating under unnecessary circumstances.

[0038] The driving gear 11 and the rack 7 are in a meshing relationship. The operator can drive the rotation of the rotating shaft 12 by rotating the handwheel 13, and then make it rotate. By the rotation of the driving gear 11, the movement of the rack 7 is realized, so that the distance between the first limiting rod 4 and the corresponding second limiting rod 6 is changed, and bars of different sizes can be adapted.

[0039] The limiting mechanism includes an internal gear ring 16 and a moving rod 18. The internal gear ring 16 is fixedly installed on the side of the fixed block 10 away from the driving gear 11. The moving rod 18 is slidably installed inside the rotating shaft 12. A limiting gear 17 is fixedly installed on one side of the moving rod 18 passing through the fixed block 10. When the limiting gear 17 is inside the internal gear ring 16, the limiting gear 17 cannot rotate, and thus the moving rod 18 and the rotating shaft 12 cannot rotate, thereby realizing the limiting function.

[0040] When the moving rod 18 slides, the limiting gear 17 also moves accordingly. The limiting gear 17 enters or exits the groove of the internal gear ring 16, thereby establishing and releasing the limiting relationship.

[0041] The other end of the moving rod 18 is fixedly installed with an operating block 14, and the operating block 14 protrudes from the rotating shaft 12.

[0042] The number of teeth of the limiting gear 17 is the same as that of the driving gear 11, and the internal gear ring 16 is provided with a groove adapted to the limiting gear 17, so that even after rotation, the limiting gear 17 can still be directly aligned with the internal gear ring 16, facilitating the insertion operation.

[0043] A scale mark 8 is inlaid on the mounting plate 2, and an indicating mark 9 is fixedly installed on the moving plate 5 at the corresponding position. Through the cooperation, the distance between the first limiting rod 4 and the corresponding second limiting rod 6 can be quickly obtained, facilitating targeted adjustment.

[0044] The working process of the present utility model: When the device is in the initial position, the distance between the first limiting rod 4 and the second limiting rod 6 is suitable for the size of the bar to be processed currently. The limiting gear 17 in the limiting mechanism is in the groove of the internal gear ring 16, so that the rotating shaft 12 is locked and cannot rotate randomly.

[0045] When it is necessary to adjust the distance between the first limiting rod 4 and the second limiting rod 6, the operator first pushes the moving rod 18 through the operating block 14 to make the limiting gear 17 exit from the groove of the internal gear ring 16, releasing the limit on the rotating shaft 12.

[0046] After the limit is released, the operator rotates the handwheel 13 to drive the rotation of the rotating shaft 12, and then drives the rotation of the driving gear 11 fixed thereon. When the driving gear 11 rotates, the rack 7 meshing with it moves accordingly. The movement of the rack 7 will drive the connecting block 15 and the moving plate 5 to slide along the fixed plate 3 together. When the moving plate 5 slides, the position of the second limiting rod 6 also changes accordingly until the required position is reached.

[0047] During the adjustment process, the scale mark 8 on the mounting plate 2 is aligned with the indicating mark 9 on the moving plate 5, showing the specific position of the second limiting rod 6, facilitating the operator to confirm whether the correct position has been adjusted.

[0048] After adjustment in place, pull the operating block 14, and the limiting gear 17 re-enters the groove of the internal gear ring 16 to re-limit the positioning.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
