Description

Technical Field

[0001] This invention relates to the field of rolling technology, and in particular to a metal sheet rolling equipment capable of multiple roll pressing. Background Technology

[0002] Metal sheet rolling equipment mainly consists of rolling mills. Rolling mills apply pressure to metal billets using rotating rolls, causing plastic deformation and rolling thick metal billets into sheets of the required thickness. During the rolling process, difficulties may arise in the metal sheet and the rolls getting into contact, especially when rolling thicker metal sheets or harder metal materials. Due to insufficient friction and other reasons, the metal sheet may not be able to smoothly enter the space between the rolls for rolling. This can lead to irregular deformation of the metal sheet during the initial entry stage into the rolls, resulting in warping, lateral bending, and other poor sheet shape during subsequent rolling. If the edges of the metal sheet billet are uneven or the thickness is uneven, uneven force can easily occur when it enters the rolls, leading to misalignment. Misalignment will compromise the dimensional accuracy of the metal sheet in both the width and rolling directions, thus affecting subsequent processing and the quality of the final product.

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figures 5-9 This is the first embodiment of the present invention. This embodiment provides a metal sheet rolling equipment that can be rolled multiple times. The metal sheet rolling equipment that can be rolled multiple times includes a rolling assembly 100, including a rolling mechanism 101. A mounting frame 102 is provided on the rolling mechanism 101, and a conveying roller 103 is provided on the mounting frame 102.

[0034] The rolling mechanism 101 comprises a working base, a transmission device, a drive motor, a control device, and other components. The working base includes components such as rolls, bearing seats, and pressing devices. Rolls are components that directly deform the metal, and their shape, size, and material are determined according to the rolling process and product requirements. The rolling mechanism 101 has three rolls, which can roll the metal plate multiple times. The mounting frame 102 is liftable. The conveying roller 103 is equipped with a drive device, which conveys the metal plate. This is existing technology, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0035] The positioning component 200 is mounted on the mounting frame 102 and includes a clamping member 201. The clamping member 201 includes a clamping plate 201a, which is located on the top of the conveying roller 103. A positioning rod 201b is fixed on one side of the clamping plate 201a, and a positioning sleeve 201c is sleeved on the outside of the positioning rod 201b. A first spring 201d is fixed at one end of the positioning rod 201b, and the other end of the first spring 201d is fixed to the inner wall of the positioning sleeve 201c.

[0036] There are two sets of positioning components 200, located on the top sides of the mounting frame 102 respectively, with both sets of positioning components 200 located on the side of the roll feed.

[0037] The positioning rod 201b is movably connected to the positioning sleeve 201c. When the metal plate approaches the space between the two clamping plates 201a, the metal plate will push the two clamping plates 201a to move outward, so that the distance between the two clamping plates 201a can accommodate the metal plate. At this time, the first spring 201d applies a pushing force to the positioning rod 201b, and the positioning rod 201b drives the clamping plates 201a to move. In this way, the clamping plates 201a can clamp the metal plate in the center, thereby avoiding the metal plate from shifting during the rolling process.

[0038] The positioning assembly 200 also includes a movable component 202, which includes a toothed plate 202a. A cavity 201a-1 is formed at the bottom of the clamping plate 201a. The toothed plate 202a is located inside the cavity 201a-1. A first gear 202b is fixed to the outside of the conveying roller 103. A fixing post 202c is fixed to the top of the toothed plate 202a. A rotating sleeve 202d is rotatably connected to the top wall of the cavity 201a-1. A fixing shaft 202e is fixed inside the rotating sleeve 202d. The fixing post 202c is mounted on... A first spiral groove 202c-1 is provided, and a fixed shaft 202e slides in the first spiral groove 202c-1. A rotating rod 202f is fixed on one side of the rotating sleeve 202d, and a connecting shaft 202g is fixed on the rotating rod 202f. A rotating rod 202h is rotatably connected to the chamber 201a-1 through a rotating shaft. One end of the rotating rod 202h extends to the outside of the chamber 201a-1, and a sliding groove 202h-1 is provided at the other end. The connecting shaft 202g slides in the sliding groove 202h-1.

[0039] The pitch of the first spiral groove 202c-1 is relatively large. Therefore, the rotating sleeve 202d can rotate by a small angle. Through the cooperation between the fixed shaft 202e and the first spiral groove 202c-1, the fixed column 202c can move downward by a longer stroke. The conveying roller 103 will drive the first gear 202b to rotate.

[0040] The rotating rod 202f is inclined. When the metal plate moves to the end of the clamping plate 201a, it will contact the end of the rotating rod 202h and squeeze one end of the rotating rod 202h. At this time, the other end of the rotating rod 202h will drive the rotating rod 202f to rotate through the sliding groove 202h-1 and the connecting shaft 202g. This causes the rotating rod 202f to drive the rotating sleeve 202d to rotate. At this time, the fixed shaft 202e and the first spiral groove 202c-1 drive the fixed column 202c to move downwards, and through the fixed column 202... 2c drives the toothed plate 202a to move downward, so that the toothed plate 202a meshes with the first gear 202b. When the first gear 202b rotates, it can drive the first gear 202b and the clamping plate 201a to move. This allows the clamping plate 201a to move with the metal plate and apply a thrust to the metal plate as it enters the rolling mill. This ensures that the metal plate can enter the rolling mill stably, thereby avoiding irregular deformation of the metal plate in the initial stage of entering the rolling mill, which would cause warping, side bending and other poor plate shape phenomena in the subsequent rolling process.

[0041] When the metal plate initially enters between the rollers, the first gear 202b moves to the end of the toothed plate 202a and separates from it, thereby stopping the clamping plate 201a from moving. When the metal plate is removed from one side of the clamping plate 201a, the pressure on the rotating rod 202h is released, allowing the toothed plate 202a to move upward and reset.

[0042] Example 2

[0043] Reference Figures 3-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0044] Specifically, the positioning component 200 also includes a locking element 203, which includes a locking block 203a. A movable groove 201b-1 is provided in the positioning rod 201b, and the locking block 203a is located in the movable groove 201b-1. A slot 201c-1 is provided on the positioning sleeve 201c. A slot 203a-1 is provided on one side of the locking block 203a, and a movable block 203c is inserted into the slot 203a-1. A second spring 203d is fixed to the inner wall of the slot 203a-1, and the other end of the second spring 203d is fixed to the movable block 203c. A third spring 203g is fixed to one side of the movable block 203c, and the other end of the third spring 203g is fixed to the inner wall of the movable groove 201b-1.

[0045] In the initial state, the third spring 203g is used to apply a pulling force to the movable block 203c. The movable block 203c applies a pulling force to the locking block 203a through the second spring 203d, so that the locking block 203a is not engaged with the locking groove 201c-1, and thus will not hinder the positioning rod 201b from moving in the positioning sleeve 201c.

[0046] Specifically, a pressing rod 203e is inserted into the positioning rod 201b, and a force-bearing groove 203c-1 corresponding to the pressing rod 203e is opened on the movable block 203c. A receiving groove 201a-2 is opened on one side of the clamping plate 201a. A force-bearing plate 203f is rotatably connected in the receiving groove 201a-2. One end of the pressing rod 203e passes through the receiving groove 201a-2 and contacts the force-bearing plate 203f.

[0047] The load-bearing plate 203f is inclined, and the inner wall of the load-bearing groove 203c-1 is inclined.

[0048] When the metal plate moves to the middle position of the clamping plate 201a, it will push the force plate 203f to rotate into the receiving groove 201a-2. At this time, the force plate 203f pushes the pressing rod 203e to move, so that the pressing rod 203e presses against the inclined surface of the inner wall of the force groove 203c-1. Through the cooperation of the two, the movable block 203c moves. The movable block 203c pushes the locking block 203a to move through the second spring 203d, so that the locking block 203a engages with the locking groove 201c-1. At this time, through the cooperation of the two, the positioning rod 201b and the clamping plate 201a can be locked, so that the clamping plate 201a cannot move away from the metal plate. This avoids the situation where the clamping plate 201a moves when the metal plate generates lateral displacement force, thus preventing the metal plate from being centered.

[0049] By setting multiple slots 201c-1, metal plates of different widths can be centered and positioned. By setting the side of the card block 203a in an inclined manner, the clamping plate 201a can move towards the metal plate, thereby allowing the clamping plate 201a to continue to apply pressure to the metal plate.

[0050] Specifically, the positioning assembly 200 also includes a rotating component 204, which includes a positioning post 204a. The positioning post 204a is fixed to one side of the clamping plate 201a. A rotating sleeve 204b is sleeved on the outside of the positioning post 204a. A second spiral groove 204a-1 is opened on the positioning post 204a. A positioning shaft 204c is fixed inside the rotating sleeve 204b. The positioning shaft 204c slides in the second spiral groove 204a-1. A second gear 204d is fixed on the outside of the rotating sleeve 204b. A rack 204e is fixed on the inside of the mounting bracket 102.

[0051] The rack 204e is relatively short and is some distance from the second gear 204d. When the metal plate enters between the two clamping plates 201a and pushes the clamping plates 201a to move, the clamping plates 201a will drive the positioning pin 204a to move into the rotating sleeve 204b. Through the cooperation of the positioning shaft 204c and the second spiral groove 204a-1, the rotating sleeve 204b will rotate. One side of the rotating sleeve 204b will be in contact with the mounting bracket 102.

[0052] When the clamping plate 201a moves, it drives the second gear 204d to approach the rack 204e. When the metal plate is about to enter the space between the rolls in the initial stage, the second gear 204d will contact the rack 204e and drive the second gear 204d to rotate through the engagement of the rack 204e. This causes the second gear 204d to drive the rotating sleeve 204b to rotate. The rotating sleeve 204b moves through the positioning shaft 204c and the positioning post 204a and clamping plate 201a that engage with the second spiral groove 204a-1. This causes the clamping plate 201a to apply a squeezing force to the metal plate. In this way, when the metal plate enters the space between the rolls, the movement of the clamping plate 201a can apply sufficient thrust to the metal plate, thereby enabling the metal plate to enter the space between the rolls stably.

[0053] Furthermore, since the rack 204e is relatively short, the second gear 204d will separate from the rack 204e after the metal plate enters the roll, thereby relieving the squeezing pressure of the clamping plate 201a on the metal plate. This allows the metal plate to move smoothly between the two clamping plates 201a after the clamping plate 201a stops moving.

[0054] Specifically, the positioning component 200 also includes a flow guide 205, which includes a flow guide plate 205a, a stabilizing shaft 205b rotatably connected to the clamping plate 201a, the flow guide plate 205a being fixed to the stabilizing shaft 205b, a torsion spring 205c being fixed to the top of the clamping plate 201a, and the other end of the torsion spring 205c being fixed to the stabilizing shaft 205b.

[0055] The guide plate 205a is inclined, and the end of the clamping plate 201a is provided with a rotating groove. The guide plate 205a is movably connected in the rotating groove. With the setting of the guide plate 205a, when the metal plate is close to the clamping plate 201a, the metal plate can be stably entered between the two clamping plates 201a. And when the clamping plate 201a moves towards the mounting frame 102, the guide plate 205a can rotate adaptively.

[0056] The stabilizing shaft 205b is used to position the guide plate 205a. The torsion spring 205c applies a torsional force to the guide plate 205a so that it can return to its original position after rotation.

[0057] Specifically, the positioning component 200 also includes a support member 206, which includes a positioning block 206a. The positioning block 206a is fixed to the top of the positioning sleeve 201c. A stabilizing column 206b is inserted into the positioning block 206a. A support block 206c is fixed to the end of the stabilizing column 206b. The support block 206c is fixed to the top of the mounting bracket 102. A fourth spring 206d is sleeved on the outside of the stabilizing column 206b. The two ends of the fourth spring 206d are fixed to the support block 206c and the positioning block 206a, respectively.

[0058] The positioning block 206a and the stabilizing column 206b work together to support the positioning sleeve 201c, and the positioning sleeve 201c can move along with the clamping plate 201a. There are two support blocks 206c, which are fixed at both ends of the stabilizing column 206b respectively, to support the stabilizing column 206b.

[0059] The fourth spring 206d applies a pulling force to the positioning block 206a, so that it can be reset after moving, and the clamping plate 201a can be reset.

[0060] Example 3

[0061] Reference Figures 1-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0062] Specifically, a support column 201e is fixed on one side of the clamping plate 201a, and a support sleeve 201f is fitted on the outside of the support column 201e.

[0063] There are two support columns 201e and support sleeves 201f, which are fixed at both ends on one side of the clamping plate 201a. The two work together to position the clamping plate 201a and prevent the clamping plate 201a from shifting when it moves.

[0064] The top of the two support sleeves 201f is also fixed with positioning blocks 206a. The positioning block 206a on the top of the support sleeve 201f is fixed on one side of the fourth spring 206d. The positioning block 206a and the support sleeve 201f are pulled by the positioning block 206a, and the clamping plate 201a can be moved and reset by the support sleeve 201f.

[0065] Specifically, a fifth spring 202i is fixed to the top of the toothed plate 202a, and the top of the fifth spring 202i is fixed to the inner wall of the chamber 201a-1.

[0066] By applying an upward pulling force to the toothed plate 202a by the fifth spring 202i, the toothed plate 202a can be reset.

[0067] Specifically, one side of the card block 203a is tilted.

[0068] Specifically, there are multiple card slots 201c-1, which are evenly distributed in a straight line on the positioning sleeve 201c.

[0069] When in use, when the metal plate approaches the space between the two clamping plates 201a, the metal plate will push the two clamping plates 201a to move outward, so that the distance between the two clamping plates 201a can accommodate the metal plate. At this time, the first spring 201d applies a pushing force to the positioning rod 201b, and the positioning rod 201b drives the clamping plate 201a to move, so that the clamping plate 201a can clamp the metal plate in the center, thereby avoiding the metal plate from shifting during the rolling process.

[0070] When the metal plate moves to the middle position of the clamping plate 201a, it will push the force plate 203f to rotate into the receiving groove 201a-2. At this time, the force plate 203f pushes the pressing rod 203e to move, so that the pressing rod 203e presses against the inclined surface of the inner wall of the force groove 203c-1. Through the cooperation of the two, the movable block 203c moves. The movable block 203c pushes the locking block 203a to move through the second spring 203d, so that the locking block 203a engages with the locking groove 201c-1. At this time, through the cooperation of the two, the positioning rod 201b and the clamping plate 201a can be locked, so that the clamping plate 201a cannot move away from the metal plate. This avoids the situation where the clamping plate 201a moves when the metal plate generates lateral displacement force, thus preventing the metal plate from being centered.

[0071] When the metal plate moves to the end of the clamping plate 201a, it will contact the end of the rotating rod 202h and squeeze one end of the rotating rod 202h. At this time, the other end of the rotating rod 202h will drive the rotating rod 202f to rotate through the sliding groove 202h-1 and the connecting shaft 202g. The rotating rod 202f drives the rotating sleeve 202d to rotate. At this time, the fixed shaft 202e drives the fixed column 202c to move downward through the cooperation of the first spiral groove 202c-1. The fixed column 202c drives the toothed plate 202a to move downward, so that the toothed plate 202a meshes with the first gear 202b. When the first gear 202b rotates, it can drive the first gear 202b and the clamping plate 201a to move, so that the clamping plate 201a can follow the metal plate.

[0072] Meanwhile, when the metal sheet is about to enter the space between the rolls in the initial stage, the second gear 204d will contact the rack 204e, and through the cooperation of the rack 204e, the second gear 204d will rotate, causing the rotating sleeve 204b to rotate. The rotating sleeve 204b moves through the positioning shaft 204c, the positioning post 204a of the second spiral groove 204a-1, and the clamping plate 201a, so that the clamping plate 201a applies a squeezing force to the metal sheet. When the clamping plate 201a moves, it can apply a thrust to the metal sheet as it enters the space between the rolls, thereby ensuring that the metal sheet can enter the space between the rolls stably, thus avoiding irregular deformation of the metal sheet in the initial stage of entering the rolls, which would cause warping, side bending, and other poor sheet shape phenomena in the subsequent rolling process.
