Description

Technical Field

[0001] The invention relates to the technical field of rolling, in particular to a metal plate rolling device capable of multiple rolling. Background Art

[0002] The main metal sheet rolling equipment is a rolling mill. A rolling mill applies pressure to a metal blank through rotating rollers, causing the metal to undergo plastic deformation, thereby rolling a thick metal blank into a sheet of the desired thickness. During the rolling process, the metal plate and the rollers may have difficulty biting into each other, especially when rolling thicker metal plates or metal materials with higher hardness. Due to insufficient friction and other reasons, the metal plate cannot smoothly enter between the rollers for rolling, which may cause irregular deformation of the metal plate during the initial entry into the rollers, resulting in warping, lateral bending and other poor plate shape during the subsequent rolling process. If the edges of the metal sheet blank are not neat or the thickness is uneven, uneven force may easily occur when entering the rollers, resulting in offset. The offset may make it impossible to guarantee the dimensional accuracy of the metal plate in the width and rolling directions, thus affecting subsequent processing and the quality of the final product.

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1 Reference Figure 1 , Figure 2 , Figure 5-Figure 9 , which is the first embodiment of the present invention, and 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, and the rolling mechanism 101 is provided with a mounting frame 102, and the mounting frame 102 is provided with a conveying roller 103.

[0032] The rolling mechanism 101 includes a working machine base, a transmission device, a driving motor, a control device and other parts. The working machine base includes rollers, bearing seats, pressing devices and other components. The rollers are components that directly deform the metal. Their shape, size and material are determined according to the rolling process and product requirements. There are three rollers on the rolling mechanism 101, which can roll the metal plate multiple times. The mounting frame 102 can be raised and lowered. A driving device is provided on the conveying roller 103, and the metal plate is conveyed by the conveying roller 103. This is the prior art and will not be elaborated in this scheme. Those skilled in the art can clearly understand the working principle.

[0033] The positioning assembly 200 is arranged on the mounting frame 102, and includes a clamping member 201, and the clamping member 201 includes a clamping plate 201a, and the clamping plate 201a is located on the top of the conveying roller 103. A positioning rod 201b is fixed to one side of the clamping plate 201a, and a positioning sleeve 201c is sleeved on the outer side of the positioning rod 201b. A first spring 201d is fixed to 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.

[0034] There are two groups of positioning components 200, which are respectively located on both sides of the top of the mounting frame 102, and both groups of positioning components 200 are located on one side of the roller feed.

[0035] The positioning rod 201b is movably connected to the positioning sleeve 201c. When the metal plate approaches the two clamping plates 201a, the metal plate will push the two clamping plates 201a to move outward and make the distance between the two clamping plates 201a able to accommodate the metal plate. At this time, the first spring 201d applies a thrust to the positioning rod 201b, and the clamping plate 201a is driven to move by the positioning rod 201b, so that the clamping plate 201a can clamp the metal plate in the center, thereby avoiding the deviation of the metal plate during the rolling process.

[0036] The positioning assembly 200 also includes a moving member 202, which includes a tooth plate 202a. A chamber 201a-1 is opened at the bottom of the clamping plate 201a. The tooth plate 202a is located in the chamber 201a-1. A first gear 202b is fixed to the outside of the conveying roller 103. A fixed column 202c is fixed to the top of the tooth plate 202a. A rotating sleeve 202d is rotatably connected to the top wall of the chamber 201a-1. A fixed shaft 202e is fixed in the rotating sleeve 202d. The fixed column 202c is fixed to the top of the first gear 202b. 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 to one side of the rotating sleeve 202d, and a connecting shaft 202g is fixed to the rotating rod 202f. A rotating rod 202h is rotatably connected to the chamber 201a-1 through the 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, and the connecting shaft 202g slides in the sliding groove 202h-1.

[0037] The pitch of the first spiral groove 202c-1 is relatively large, so when the rotating sleeve 202d rotates a smaller angle, the fixed column 202c can move downward a longer stroke through the cooperation between the fixed shaft 202e and the first spiral groove 202c-1, and the conveying roller 103 will drive the first gear 202b to rotate.

[0038] 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 cooperate with the connecting shaft 202g through the sliding groove 202h-1 to drive the rotating rod 202f to rotate, so that the rotating rod 202f drives the rotating sleeve 202d to rotate. At this time, the fixed shaft 202e and the first spiral groove 202c-1 are used to drive the fixed column 202c to move downward, and through the fixed column 20 2c drives the tooth plate 202a to move downward, so that the tooth plate 202a is engaged 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 move with the metal plate and apply a thrust to the metal plate entering between the rollers, thereby ensuring that the metal plate can stably enter between the rollers, thereby avoiding irregular deformation of the metal plate in the initial stage of entering the rollers, resulting in poor plate shape phenomena such as warping and side bending during the subsequent rolling process.

[0039] When the metal plate initially enters between the rollers, the first gear 202b will move to the end of the tooth plate 202a and separate from the tooth plate 202a, thereby stopping the movement of the clamping plate 201a. When the metal plate moves away from one side of the clamping plate 201a, the squeezing of the rotating rod 202h can be released, allowing the tooth plate 202a to move upward and reset.

[0040] Example 2 Reference Figure 3-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0041] Specifically, the positioning assembly 200 also includes a locking piece 203, which includes a card block 203a. A movable groove 201b-1 is provided in the positioning rod 201b, and the card block 203a is located in the movable groove 201b-1. A card slot 201c-1 is provided on the positioning sleeve 201c. A slot 203a-1 is provided on one side of the card block 203a. 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.

[0042] In the initial state, the third spring 203g is used to apply tension to the movable block 203c, and the movable block 203c applies tension to the clamping block 203a through the second spring 203d, so that the clamping block 203a will not be engaged with the clamping slot 201c-1, thereby not hindering the movement of the positioning rod 201b in the positioning sleeve 201c.

[0043] Specifically, an extrusion rod 203e is inserted into the positioning rod 201b, a force groove 203e-1 corresponding to the extrusion rod 203e is provided on the movable block 203c, a receiving groove 201a-2 is provided on one side of the clamp 201a, a force plate 203f is rotatably connected to the receiving groove 201a-2, one end of the extrusion rod 203e passes through the receiving groove 201a-2 and contacts the force plate 203f.

[0044] The force-bearing plate 203f is inclined, and the inner wall of the force-bearing groove 203e-1 is inclined.

[0045] When the metal plate moves to the middle position of the splint 201a, it will push the force-bearing plate 203f to rotate into the accommodating groove 201a-2. At this time, the force-bearing plate 203f pushes the extrusion rod 203e to move, so that the extrusion rod 203e squeezes the inner wall slope of the force-bearing groove 203e-1, and the two cooperate to drive the movable block 203c to move. The movable block 203c pushes the clamping block 203a to move through the second spring 203d, so that the clamping block 203a is engaged with the clamping groove 201c-1. At this time, the positioning rod 201b and the splint 201a can be locked by the cooperation of the two, so that the splint 201a cannot move away from the metal plate, thereby avoiding the situation that when the metal plate generates a force for lateral displacement, the splint 201a will move, thereby failing to center the metal plate.

[0046] By setting up multiple card slots 201c-1, metal plates of different widths can be centered, and by setting up the inclined side of the card block 203a, the clamping plate 201a can be moved toward the metal plate, so that the clamping plate 201a can continue to apply squeezing force to the metal plate.

[0047] Specifically, the positioning assembly 200 also includes a rotating member 204, which includes a positioning column 204a, which is fixed to one side of the clamping plate 201a, and a rotating sleeve 204b is sleeved on the outer side of the positioning column 204a. A second spiral groove 204a-1 is opened on the positioning column 204a, and a positioning shaft 204c is fixed in the rotating sleeve 204b. The positioning shaft 204c slides in the second spiral groove 204a-1, a second gear 204d is fixed on the outer side of the rotating sleeve 204b, and a rack 204e is fixed on the inner side of the mounting frame 102.

[0048] The rack 204e is shorter and is some distance away from the second gear 204d. When the metal plate enters between the two clamps 201a and pushes the clamp 201a to move, the clamp 201a will drive the positioning column 204a to move into the rotating sleeve 204b, and drive the rotating sleeve 204b to rotate through the cooperation of the positioning shaft 204c and the second spiral groove 204a-1. One side of the rotating sleeve 204b is in contact with the mounting frame 102.

[0049] When the clamping plate 201a moves, it will drive the second gear 204d to approach the rack 204e. When the metal plate is about to enter between the rollers in the initial stage, the second gear 204d will contact the rack 204e and drive the second gear 204d to rotate through the cooperation of the rack 204e, so that the second gear 204d drives the rotating sleeve 204b to rotate. The rotating sleeve 204b moves through the positioning shaft 204c and the second spiral groove 204a-1 through the positioning column 204a and the clamping plate 201a, so that the clamping plate 201a applies a squeezing force to the metal plate, so that when the metal plate enters between the rollers, the movement of the clamping plate 201a can apply sufficient thrust to the metal plate, thereby allowing the metal plate to stably enter between the rollers.

[0050] And because the rack 204e is short, after the metal plate enters the roller, the second gear 204d will separate from the rack 204e, thereby releasing the squeezing force of the clamping plate 201a on the metal plate, and then the metal plate can move smoothly between the two clamping plates 201a after the clamping plate 201a stops moving.

[0051] Specifically, the positioning assembly 200 also includes a guide member 205, which includes a guide plate 205a, a stabilizing shaft 205b rotatably connected to the clamp 201a, the guide plate 205a is fixed to the stabilizing shaft 205b, a torsion spring 205c is fixed to the top of the clamp 201a, and the other end of the torsion spring 205c is fixed to the stabilizing shaft 205b.

[0052] The guide plate 205a is inclined, and a rotating groove is opened at the end of the clamping plate 201a. The guide plate 205a is movably connected in the rotating groove. Through the setting of the guide plate 205a, when the metal plate is close to the clamping plate 201a, the metal plate can stably enter between the two clamping plates 201a, and when the clamping plate 201a moves toward the mounting frame 102, the guide plate 205a can rotate adaptively.

[0053] The stabilizing shaft 205b is used to position the guide plate 205a, and a torsion force is applied to the guide plate 205a through the torsion spring 205c so that the guide plate 205a can be reset after being rotated.

[0054] Specifically, the positioning assembly 200 also includes a support member 206, and the support member 206 includes a positioning block 206a, which is fixed to the top of the positioning sleeve 201c. A stabilizing column 206b is inserted into the positioning block 206a, and 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 frame 102, and a fourth spring 206d is sleeved on the outer side of the stabilizing column 206b. The two ends of the fourth spring 206d are respectively fixed to the support block 206c and the positioning block 206a.

[0055] The positioning block 206a cooperates with the stabilizing column 206b to support the positioning sleeve 201c, and when the splint 201a moves, the positioning sleeve 201c can follow the movement. There are two support blocks 206c, which are fixed at both ends of the stabilizing column 206b respectively, to support the stabilizing column 206b.

[0056] 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.

[0057] Example 3 Reference Figure 1-Figure 9 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0058] Specifically, a support column 201e is fixed to one side of the clamping plate 201a, and a support sleeve 201f is sleeved on the outer side of the support column 201e.

[0059] There are two support columns 201e and two support sleeves 201f, which are respectively fixed at two ends of one side of the clamping plate 201a. The two are used to position the clamping plate 201a through cooperation to prevent the clamping plate 201a from being offset when moving.

[0060] The two support sleeves 201f are also fixed with positioning blocks 206a on top. The positioning block 206a on the top of the support sleeve 201f on one side of the fourth spring 206d is fixed. The positioning block 206a applies tension to the positioning block 206a and the support sleeve 201f, and the support sleeve 201f can drive the splint 201a to move and reset.

[0061] Specifically, a fifth spring 202i is fixed to the top of the tooth plate 202a, and the top end of the fifth spring 202i is fixed to the inner wall of the chamber 201a-1.

[0062] The fifth spring 202i applies an upward pulling force to the tooth plate 202a, so that the tooth plate 202a can be reset.

[0063] Specifically, one side of the block 203a is inclined.

[0064] Specifically, there are multiple slots 201c-1, which are evenly distributed in a straight line on the positioning sleeve 201c.

[0065] During use, when the metal plate approaches between the two clamps 201a, the metal plate will push the two clamps 201a to move outward and make the distance between the two clamps 201a able to accommodate the metal plate. At this time, the first spring 201d applies a thrust to the positioning rod 201b, and the positioning rod 201b drives the clamp 201a to move, so that the clamp 201a can clamp the metal plate in the center, thereby avoiding the deviation of the metal plate during the rolling process.

[0066] When the metal plate moves to the middle position of the splint 201a, it will push the force-bearing plate 203f to rotate into the accommodating groove 201a-2. At this time, the force-bearing plate 203f pushes the extrusion rod 203e to move, so that the extrusion rod 203e squeezes the inner wall slope of the force-bearing groove 203e-1, and the two cooperate to drive the movable block 203c to move. The movable block 203c pushes the clamping block 203a to move through the second spring 203d, so that the clamping block 203a is engaged with the clamping groove 201c-1. At this time, the positioning rod 201b and the splint 201a can be locked by the cooperation of the two, so that the splint 201a cannot move away from the metal plate, thereby avoiding the situation that when the metal plate generates a force for lateral displacement, the splint 201a will move, thereby failing to center the metal plate.

[0067] When the metal plate moves to the end of the splint 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 cooperate with the connecting shaft 202g through the slide groove 202h-1 to drive the rotating rod 202f to rotate, so that the rotating rod 202f drives the rotating sleeve 202d to rotate. At this time, the fixed column 202c is driven to move downward through the cooperation of the fixed shaft 202e and the first spiral groove 202c-1, and the tooth plate 202a is driven downward through the fixed column 202c, so that the tooth plate 202a is engaged with the first gear 202b. When the first gear 202b rotates, it can drive the first gear 202b and the splint 201a to move, so that the splint 201a can follow the movement of the metal plate.

[0068] At the same time, when the metal plate is about to enter between the rollers in the initial stage, the second gear 204d will contact the rack 204e, and drive the second gear 204d to rotate through the cooperation of the rack 204e, so that the second gear 204d drives the rotating sleeve 204b to rotate, and the rotating sleeve 204b moves through the positioning shaft 204c and the second spiral groove 204a-1 through the matching positioning column 204a and the clamping plate 201a, so that the clamping plate 201a applies a squeezing force to the metal plate. When the clamping plate 201a moves, it can apply a thrust to the metal plate entering between the rollers, thereby ensuring that the metal plate can stably enter between the rollers, thereby avoiding irregular deformation of the metal plate in the initial stage of entering the rollers, resulting in warping, side bending and other poor plate shape phenomena in the subsequent rolling process.
