Description

Technical Field

[0001] This utility model relates to the field of rolling machine technology, and in particular to a rolling wheel adjustment device for a rolling machine. Background Technology

[0002] Steel composite brake drums are a product developed in recent years. Since their market launch, customer feedback has been positive, with a service life significantly longer than ordinary gray iron brake drums. The steel composite brake drum blank is made from a steel shell through centrifugal casting. The steel shell is formed from steel plates through blanking, spinning, and rolling. The rolling process involves a rolling mold supporting the inner wall of the steel shell, and after the rolling wheels are adjusted to a suitable height, the outer circumference of the steel shell is rolled to produce a steel shell with a wavy structure.

[0003] In existing technology, roll forming machines use limit switches to adjust the height of the roll forming roller. The limit switch is mounted on a bracket, and its position is adjusted according to actual conditions to ensure the roll forming roller stops accurately at the limit switch. When adjusting the roll forming roller height, the fixing screws are first loosened, the limit switch is moved to the appropriate position, and then the screws are tightened. Moving the limit switch manually up and down results in inconsistent adjustments, sometimes too much and sometimes too little. Since the convex and concave positions of the roll forming roller and the roll forming die need to be precisely aligned, many adjustments are often required to achieve the correct position.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, such as Figure 1 As shown, a roller position adjustment device for a roller forming machine includes a support 1. In actual use, the support is slidably mounted on the frame of the roller forming machine and can move relative to the frame under the action of a horizontal drive component. An L-shaped roller base 3 is provided on one side of the support 1 relative to the roller forming mold 2, and a horizontal drive component 6 is provided on the other side. The horizontal drive component drives the support to move horizontally relative to the roller forming mold 2, adjusting the horizontal distance between the roller on the L-shaped roller base and the roller forming mold. The support 1 is provided with a vertical guide groove 4, and a vertically arranged lead screw 5 is rotatably installed in the vertical guide groove 4. The L-shaped rolling wheel base 3 is provided with a nut block 7 that cooperates with the vertical guide groove 4. The nut block 7 is threadedly engaged with the lead screw 5. The L-shaped rolling wheel base 3 is provided with a rolling wheel 8. The nut block is provided with a threaded hole, and the lead screw is threadedly engaged with the threaded hole. Rotating the lead screw drives the threaded block to move up and down. The L-shaped rolling wheel base is fixedly connected to the threaded block. Therefore, the L-shaped rolling wheel base moves up and down with the threaded block, thereby realizing the height adjustment of the rolling wheel and facilitating the correspondence of the convex and concave arcs of the rolling wheel and the rolling die. The above adjustment method is simple, highly accurate, and improves the accuracy of the rolling wheel position adjustment.

[0022] like Figure 2As shown in this embodiment, the rolling die is supported and fixed on the rolling die base by bearings. The position of the rolling die is adjusted by adjusting the height of the shims. The upper end of the rolling die is fixed by a ring and a locking nut. The upper part of the vertical guide groove 4 is provided with a stepped groove 41 that is connected to the vertical guide groove. The upper part of the lead screw 5 is provided with a support protrusion 51 that cooperates with the stepped groove 41. The support protrusion 51 is used for axial positioning of the lead screw and to ensure its rotational stability. The lead screw 5 is limited on the support 1 by the first pressure cover 10. That is, the first pressure cover presses the support protrusion 51 into the stepped groove 41. The upper part of the lead screw 5 extends upward from the first pressure cover, ensuring the stability of the lead screw without affecting its rotation. The top of the lead screw 5 is detachably provided with a handle. The lead screw is rotated by the handle. The thread pitch of the lead screw 5 is 2mm. The height moves 2mm with one revolution. During adjustment, the lead screw can be rotated at any angle, and the height movement position is accurate, which facilitates the correspondence of the convex and concave arcs of the rolling wheel and the rolling die.

[0023] Example 2: A rolling mill roller position adjustment device, which is further optimized based on Example 1. In this example, the support 1 is provided with a vertically arranged guide groove 11, and the back of the L-shaped rolling mill roller base 3 matches the guide groove 11; the cooperation between the L-shaped rolling mill roller base and the guide groove improves the stability of the L-shaped rolling mill roller base during the up and down movement process.

[0024] Furthermore, the horizontal drive component 6 includes a horizontal hydraulic rod 61. The telescopic end of the horizontal hydraulic rod 61 is threadedly connected to the connecting seat 62 and locked by a locking nut I 63. That is, the telescopic end of the horizontal hydraulic rod 61 has an external thread, and the connecting seat has an internal threaded hole. The external thread mates with the internal thread of the internal threaded hole, and then the locking nut I 63 is used to lock it. The purpose of locking is to prevent the thread from loosening. The connecting seat 62 is connected to the support 1 by bolts 64. The horizontal hydraulic rod 61 is a horizontally positioned hydraulic cylinder. The hydraulic cylinder provides the power for the horizontal movement of the support. The horizontal hydraulic rod 61 extends to push the support to move, adjusting the horizontal lateral distance between the rolling wheel and the rolling die.

[0025] As a preferred embodiment, the support 1 is an L-shaped base with a clearance groove 12 corresponding to the L-shaped roller base 3. The clearance groove 12 avoids interference during the vertical movement of the L-shaped roller base, and the L-shaped design of the support improves the stability of the support for the L-shaped roller base; moreover, it makes the horizontal movement of the support more stable.

[0026] Example 3, as Figure 3As shown, a roller forming machine position adjustment device is further optimized based on embodiment 1 or 2. In this embodiment, the L-shaped roller forming machine base 3 is provided with an end cover 9, which is fixed to the L-shaped roller forming machine base by bolts. A positioning key 15 is provided between the end cover 9 and the top of the L-shaped roller forming machine base 3. The positioning key 15 is used to position the end cover, which facilitates the quick installation of the end cover and the L-shaped roller forming machine base. The roller forming machine 8 is rotatably disposed between the L-shaped roller forming machine base 3 and the end cover 9. The roller forming machine 8 is correspondingly disposed with the roller forming mold.

[0027] like Figure 4 As shown, the rolling wheel 8 in this embodiment includes a spindle 81 and a wheel body 82. The wheel body 82 is fixed to the spindle 81 by a locking nut II 83 and rotates synchronously with the spindle. The bottom of the wheel body 82 is provided with a positioning groove 84, which cooperates with the positioning protrusion 31 provided at the lower part of the spindle 81. The positioning groove and the positioning protrusion cooperate to limit the axial and radial movement of the wheel body, ensuring the stability of the wheel body installation.

[0028] As a preferred embodiment, the upper part of the mandrel 81 is rotatably connected to the end cover 9 via a first cylindrical roller bearing 85, and the lower part of the mandrel 81 is rotatably connected to the L-shaped rolling wheel base 3 via a second cylindrical roller bearing 86 and an end thrust roller bearing 87. The end cover 9 has a second pressure cap 13 on its upper side to seal the mandrel 81, and an oil seal pressure cap 14 on its lower side to seal the mandrel 81. That is, the lower end of the rolling wheel base is equipped with a thrust roller bearing and a second cylindrical roller bearing to withstand axial and radial forces; the end cover is equipped with a first cylindrical roller bearing to withstand radial forces. The second pressure cap is fixed to the upper end of the end cover to press the bearings together. The oil seal pressure cap is fixed to the lower end of the end cover to prevent grease leakage. Adjusting the nut drives the rolling wheel base and this series of components to move up and down.

[0029] The specific usage process of this utility model is as follows: After the rolling die is fixed, the horizontal drive component pushes the rolling wheel laterally closer to the rolling die, requiring the convex and concave arcs of the rolling wheel and the rolling die to correspond one-to-one. This ensures that the rolled steel shell has a uniform wall thickness and meets the required shape. If the height direction of the convex and concave arcs of the rolling wheel and the rolling die does not correspond one-to-one, the height of the rolling wheel needs to be adjusted. During adjustment, the lead screw is rotated, which drives the adjusting nut block to move up and down. The adjusting nut block drives the L-shaped rolling wheel base to move up and down. The rolling wheel is mounted on the L-shaped rolling wheel base and moves up and down with the base. The lead screw has a lead screw pitch of 2mm, and the height moves 2mm with each rotation. During adjustment, the lead screw can rotate at any angle, and the height direction movement is accurate, facilitating the correspondence between the convex and concave arcs of the rolling wheel and the rolling die.
