Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of color steel plate production, more specifically, the present application relates to a roll forming equipment for color steel plate production. BACKGROUND

[0002] As a building material with multiple advantages such as light weight, high strength, heat preservation, fireproofing, and aesthetics, color steel plate is widely used in the roofing and wall enclosure structures of various buildings such as workshops, warehouses, mobile homes, and stadiums, as well as in the industrial fields of household appliance casings and automotive interiors. The core production process is to gradually extrude and bend continuous metal coils (such as galvanized sheets and color-coated sheets) into a preset cross-sectional shape (such as a corrugated shape, a trapezoidal shape, an angular shape, etc.) through roll forming equipment. This process has the characteristics of high production efficiency, stable forming precision, high material utilization rate, and high automation level, and has become a core technical means for the large-scale production of color steel plates.

[0003] For example, the patent with publication number CN118976813B and publication date April 1, 2025 discloses a metal sandwich plate roll forming device, which includes a conveyor, multiple roller sets arranged in pairs inside the conveyor, and a cutting machine arranged at the discharge port of the conveyor. The front and rear inner walls of the conveyor loading port are each provided with two symmetrically arranged guide springs, and a gap is left between the two guide springs for the metal sandwich plate to pass through. The guide spring is composed of a horizontal plate fixedly connected to the inner wall of the conveyor and a warping plate abutting against the inner wall of the conveyor. Each guide spring is slidably connected to a pressure wheel through a first elastic member. A pushing member is arranged between the conveyor and the cutting machine to make the pressure wheel move away from the horizontal plate while approaching the warping plate. This application can make the unwinding end of the metal sandwich plate enter the rolling gap more accurately and normally carry out subsequent roll forming work.

[0004] The existing color steel plate is usually wound in a rolled manner on a winding roller in the initial state. As in the above-mentioned authorized patent, when the color steel plate is unwound and enters the rolling gap between the upper and lower rollers, a guide spring is used to guide and limit the metal sandwich plate and pre-press it flat, reducing the probability that the unwinding end of the metal sandwich plate cannot enter the rolling gap accurately due to warping. However, when the color steel plate enters the guide spring, the surface of the color steel plate will rub against the guide spring. Since the existing color steel plate surface has a coating, such as a polyester coating or a silicon-modified polyester coating, the friction between the two when the color steel strip enters and passes through the guide spring will cause the coating on the surface of the color steel strip to be scratched or removed, thereby affecting the subsequent use of the color steel strip.

DETAILED DESCRIPTION

[0031] It is necessary to point out here that the following detailed description is only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application.

[0033] The present application provides a roll forming equipment for color steel plate production, which comprises a unwinding mechanism 1, a steel coil 2, a guide roller assembly 4 and a roll forming mechanism 5.

[0034] The present application further comprises a leveling mechanism 3 and a support 6 arranged between the unwinding mechanism 1 and the guide roller assembly 4, the leveling mechanism 3 comprises a rotating frame 31, a first cylinder 32, a clamping plate 33 and a conveying roller 34, the rotating frame 31 is driven to rotate on the support 6, the first cylinder 32 is fixedly connected to the rotating frame 31, the clamping plate 33 is fixedly connected to the output end of the first cylinder 32, and the conveying roller 34 is movably installed on the clamping plate 33, the leveling mechanism 3 has an inclined state and a horizontal state, and the leveling mechanism 3 is initially in the inclined state, and at this time, the conveying roller 34 is accommodated in the clamping plate 33, and when the leveling mechanism 3 is in the horizontal state, the conveying roller 34 extends out of the clamping plate 33.

[0035] It should be noted that the unwinding mechanism 1, the leveling mechanism 3, the guide roller assembly 4 and the roll forming mechanism 5 are arranged in sequence along the conveying direction of the steel strip, the unwinding mechanism 1 is rotatably installed with an unwinding roller, the steel coil 2 is sleeved on the unwinding roller, the steel coil 2 is coaxially sleeved and locked outside the unwinding roller, the guide roller assembly 4 is installed on one side of the unwinding mechanism 1 through the support 6, the roll forming mechanism 5 is connected to the side of the guide roller assembly 4 away from the unwinding mechanism 1, the steel strip extending out of the steel coil is rolled and formed by the roller group in the roll forming mechanism 5, and the clamping plate 33 and the first cylinder 32 are symmetrically provided with two groups, the first cylinder 32 is symmetrically fixed to the outer side wall of the rotating frame 31 through bolts, a sliding groove is formed in the inner wall of the rotating frame 31, sliding blocks are arranged on the two side surfaces of the clamping plate 33 in the width direction, the sliding blocks are located in the sliding groove and form sliding guide cooperation with the sliding groove, in this embodiment, a cylinder is also arranged in the clamping plate 33, the conveying roller 34 is controlled to extend into and out of the clamping plate 33 through the cylinder, a servo motor 62 is installed on the support 6, the output end of the servo motor 62 is connected to the rotating frame 31 and drives the rotating frame 31 to rotate on the support 6, that is, the leveling mechanism 3 is switched back and forth between the inclined state and the horizontal state.

[0036] The guide roller assembly 4 comprises a guide roller frame 41 and a roller group 42, and the roller group 42 is rotatably arranged on the guide roller frame 41.

[0037] Meanwhile, limit stop grooves 333 are formed on the two clamping plates 33, the groove direction of the limit stop grooves 333 is consistent with the width direction of the clamping plates 33, a sliding frame 35 is arranged on the limit stop grooves 333, the sliding frame 35 is slidingly connected to the limit stop grooves 333, and the transmission roller 34 is rotatably installed on the sliding frame 35. The sliding frame 35 is fixedly connected with a connecting plate 36, the connecting plate 36 extends to one side of the clamping plate 33 close to the unwinding mechanism 1, and the first motor 37 is fixedly installed on the connecting plate 36. The conveying roller 38 is rotatably installed on the connecting plate 36.

[0038] Specifically, the output end of the first motor 37 is fixedly connected with the conveying roller 38, and the outer shaft surface of the conveying roller 38 is in the same plane as the outer shaft surface of the transmission roller 34.

[0039] It needs to be further supplemented that, as shown in Figures 1-3 the initial state of the flattening mechanism 3 is inclined, the upper end opening of the flattening mechanism 3 faces the unwinding mechanism 1, the unwinding mechanism 1 drives the steel coil 2 to rotate, and the end of the steel strip is placed between the two groups of clamping plates 33 by manual operation. The first cylinder 32 is started, the output end pushes the two groups of clamping plates 33 to move close to each other, and the end of the steel strip is clamped between the two groups of clamping plates 33. The clamping force generated by the clamping of the two groups of clamping plates 33 is used to press and flatten the steel strip. Then, the flattening mechanism 3 is driven to rotate on the support 6 until the flattening mechanism 3 is in a horizontal state. Then, the first cylinder 32 drives the two groups of clamping plates 33 to move away from each other and slightly open the gap between the two groups of clamping plates 33. At the same time, the transmission roller 34 extends from the inside of the clamping plate 33. At this time, the end of the steel coil 2 is limited between the two groups of transmission rollers 34 and the upper and lower conveying rollers 38. Then, the first motor 37 is started, the conveying roller 38 is driven to rotate by the first motor 37, and then under the cooperation of the transmission roller 34, the end of the steel coil 2 is horizontally moved, that is, horizontally moved between the two groups of clamping plates 33 and sent out from the two groups of clamping plates 33. The end of the steel coil 2 after being sent out enters between the roller groups 42 and passes through the guide roller assembly 4 to enter the roller pressing mechanism 5. The roller pressing mechanism 5 is used to realize the roller pressing and forming of the color steel plate. In this embodiment, the flattening of the end of the steel coil 2 can be realized by the clamping of the two groups of clamping plates 33, which can avoid the problem that the end is raised and cannot enter the roller pressing mechanism 5. Secondly, by the active flattening method and the extension of the transmission roller 34 in the horizontal state, the friction between the steel strip and the clamping plate 33 in the flattening and conveying process can be reduced, and the phenomenon that the coating on the surface of the steel strip and the color steel plate is scratched can be avoided. At the same time, the retraction of the transmission roller 34 in the inclined state can avoid the flattening of other positions of the steel strip in the flattening process, causing the surface of the steel strip to have indentations or pits, thereby affecting the subsequent use of the steel strip.

[0040] In the above embodiment, as shown in Figure 4 and Figure 5As shown, the axis position of the rotating of the flattening mechanism 3 is horizontal with the position of the output end of the steel strip roll, when the flattening mechanism 3 is in the inclined state, the end of the flattening mechanism 3 close to the steel strip is upturned, and the end is above the rotating axis, then the steel strip enters into the flattening mechanism 3 and is clamped, at this time, the distance between the end of the flattening mechanism 3 close to the steel strip and the steel strip roll is fixed, that is, the length of the steel strip extended from the steel strip roll is fixed, when the flattening mechanism 3 rotates to the horizontal state, the distance between the end of the flattening mechanism 3 close to the steel strip and the steel strip is shortened, and the length of the steel strip extended from the steel strip roll is unchanged, which causes the steel strip to be bent between the steel strip roll and the flattening mechanism 3 after rotation, even the steel strip is bent by the rotation of the flattening mechanism 3, in order to avoid the bending phenomenon, in another embodiment of the present application, the support 6 is driven to move horizontally between the unwinding mechanism 1 and the guide roller assembly 4.

[0041] It should be noted that the guide roller assembly 4 further comprises a support frame 43 installed on the guide roller frame 41, the support frame 43 is provided with a guide groove 44, the groove direction of the guide groove 44 is consistent with the conveying direction of the steel strip, the lower end of the support 6 is located in the guide groove 44 and forms a sliding guide cooperation with the guide groove 44, the second cylinder 61 is further installed between the support 6 and the unwinding mechanism 1, the output end of the second cylinder 61 is fixedly connected with the support 6, and the fixed end of the second cylinder 61 is fixedly connected with the unwinding mechanism 1; when the two groups of clamping plates 33 clamp the steel strip in the inclined state, the servo motor 62 drives the two groups of clamping plates 33 to rotate from the inclined state to the horizontal state, and in the rotating process, the second cylinder 61 drives the support 6 to move horizontally to the side close to the guide roller assembly 4, at this time, the support 6 slides in the guide groove 44, and the distance between the end of the clamping plate 33 close to the unwinding mechanism 1 and the steel strip in the horizontal state is increased by the sliding of the support 6, so that the steel strip is always in the straightened state between the flattening mechanism 3 and the unwinding mechanism 1 before and after rotation, avoiding the bending or bending phenomenon of the steel strip after the rotation of the flattening mechanism 3.

[0042] In the above embodiment, because the servo motor 62 drives the two sets of clamping plates 33 to rotate from the inclined state to the horizontal state, and due to the influence of the rotation radius of the clamping plates 33 and the height of the clamping plates 33, in order to avoid interference with the rotation of the clamping plates 33, the guide roller assembly 4 should be arranged outside the rotation radius of the clamping plates 33, thus resulting in a certain gap between the guide roller assembly 4 and the clamping plates 33 in the horizontal state. In addition, the thickness of the existing color steel plate, i.e. steel strip, is usually between 0.2mm-0.6mm, that is, the thickness of the steel strip is relatively thin, and the flexibility and bending performance of the steel strip are relatively high and easy to deform. When the color steel plate, i.e. steel strip, with high bending performance is stretched out from between the two sets of clamping plates 33 in the horizontal state, because there is still a certain gap between the guide roller assembly 4 and the clamping plates 33 in the horizontal state, the end of the color steel plate, i.e. steel strip, is easy to bend downward in the gap due to gravity, which makes it difficult for the end of the color steel plate, i.e. steel strip, to stretch into the upper roller set 42 of the guide roller assembly 4 during the subsequent conveying process of the steel strip, and thus it is also difficult to be conveyed to the roller pressing mechanism 5 through the upper roller set 42 of the guide roller assembly 4, which affects the subsequent roller pressing of the color steel plate, i.e. steel strip. Therefore, in another embodiment of the application, the clamping plate 33 comprises a first clamping plate 331 and a second clamping plate 332, the second clamping plate 332 is located at one end of the first clamping plate 331 close to the guide roller assembly 4, and the second clamping plate 332 is rotationally connected to the first clamping plate 331. The first clamping plate 331 is also provided with a second motor 334 connected to the rotation connection between the first clamping plate 331 and the second clamping plate 332.

[0043] Specifically, the sliding frame 35 is slidingly installed on the first clamping plate 331, the output end of the first cylinder 32 penetrates the rotating frame 31 and is fixedly connected to the first clamping plate 331. The sliding block is provided with two sets, and the two sets of sliding blocks are fixedly installed on the two side surfaces of the first clamping plate 331. The two sets of second clamping plates 332 clamp the end of the steel strip.

[0044] When the clamping plate 33 is in the inclined state, the lower plate surface of the second clamping plate 332 and the first clamping plate 331 is horizontal, and the two groups of corresponding second clamping plates 332 clamp the end of the steel strip. After the clamping plate 33 is rotated from the inclined state to the horizontal state, the second clamping plate 332 flattens the end of the steel strip for a certain period of time in the process, and then the second motor 334 drives the second clamping plate 332 to rotate on the first clamping plate 331, that is, the end of the second clamping plate 332 away from the first clamping plate 331 rotates away from the end of the steel strip, that is, the second clamping plate 332 is perpendicular to the first clamping plate 331 at this time, and the second clamping plate 332 is separated from the clamping of the end of the steel coil 2, that is, the end of the steel coil 2 is exposed in the clamping plate 33 at this time. Since the exposed part is small, the degree of bending is small, so during the subsequent horizontal movement of the support 6 and the flattening mechanism 3, the flattening mechanism 3 can insert the exposed end of the steel strip between the roller sets 42 of the guide roller assembly 4, and then drive the conveying roller 38 to rotate by the first motor 37, and then drive the conveying roller 38 to rotate. The steel strip is actively fed, which can avoid the bending phenomenon in the process of self-movement of the steel strip. In addition, the second clamping plate 332 after rotation will not block and interfere with the insertion of the end of the steel strip. Then, the first cylinder 32 drives the two groups of clamping plates 33 away from each other, and the conveying roller 34 extends out of the first clamping plate 331, thereby achieving the conveying of the steel strip.

[0045] In an optional embodiment, the extension and fixation of the conveying roller 34 are directly controlled by the cylinder built in the clamping plate 33, but in actual use, there is a risk of misoperation. When the cylinder control signal is abnormal or misoperated, the conveying roller 34 may extend out of the clamping plate 33 in the inclined state. At this time, the extension of the conveying roller 34 not only affects the flattening of the end of the steel strip, but also forms a concave defect on the surface of the steel strip, thereby affecting the appearance quality of the product. In order to avoid the above phenomenon, in another embodiment of the present application, a locking mechanism 7 is further included, which is arranged between the support 6 and the sliding frame 35. When the flattening mechanism 3 is in the inclined state, the locking mechanism 7 is used to limit and lock the conveying roller 34 in the clamping plate 33. When the flattening mechanism 3 is in the horizontal state, the locking mechanism 7 passively drives the conveying roller 34 to extend out of the clamping plate 33.

[0046] The locking mechanism 7 includes a limiting groove 71, an annular groove 72, a limiting column 73 and a spring 74. The limiting groove 71 and the annular groove 72 are both arranged on the side surface of the support 6 close to the rotating frame 31, and the limiting groove 71 and the annular groove 72 are communicated with each other. The limiting column 73 is fixedly connected to the side surface of the sliding frame 35 close to the rotating frame 31. The spring 74 is fixedly connected between the sliding frame 35 and the first clamping plate 331.

[0047] Specifically, the outer groove wall of the annular groove 72 is communicated with one groove end of the limiting groove 71, one end of the limiting column 73 extends into the corresponding limiting groove 71 or the annular groove 72, the limiting groove 71 and the limiting column 73 are both provided with two groups, and the two groups of limiting grooves 71 and limiting columns 73 are symmetrically distributed on the two sides of the clamping plate 33; in the initial preparation stage, the flattening mechanism 3 is in an inclined state, the spring 74 supports the sliding frame 35 and limits it in the first clamping plate 331, so that the outer shaft surface of the conveying roller 34 and the clamping surface of the clamping plate 33 remain in the same plane, or the conveying roller 34 is always located in the first clamping plate 331, at this time, one end of the limiting column 73 is located in the limiting groove 71, when the person places the end of the steel roll 2 between the two groups of clamping plates 33, ensures that the end of the steel belt is in the clamping area of the second clamping plate 332, starts the first cylinder 32, the output end of the first cylinder 32 drives the two clamping plates 33 to move close to each other, the conveying roller 34 is in contact with the surface of the steel belt at the same time, with the movement of the clamping plate 33, one end of the limiting column 73 on the sliding frame 35 slides in the limiting groove 71 at the same time, until the clamping plate 33 clamps the steel belt tightly, one end of the limiting column 73 enters the annular groove 72, then starts the servo motor 62, drives the rotating frame 31 to drive the flattening mechanism 3 to rotate from the inclined state to the horizontal state, in the rotating process, the limiting column 73 slides along the annular groove 72, at the same time, the conveying roller 34 always adheres to the steel belt under the cooperation of the limiting column 73 and the annular groove 72, after the flattening mechanism 3 rotates to the horizontal state, the servo motor 62 brakes and locks, to ensure that the posture of the rotating frame 31 is stable, at this time, the limiting column 73 is still in the annular groove 72, maintains the position of the sliding frame 35 fixed, starts the first cylinder 32, the output end of the first cylinder 32 drives the two clamping plates 33 to move away from each other, because the limiting column 73 is limited by the annular groove 72, the sliding frame 35 does not move synchronously with the clamping plate 33, that is, at this time, the conveying roller 34 moves relative to the clamping plate 33, the conveying roller 34 is passively stretched out of the clamping plate 33 and maintains contact with the steel belt, starts the first motor 37 to drive the conveying roller 38 to rotate, cooperates with the supporting action of the conveying roller 34, drives the steel belt to be horizontally conveyed to the side close to the guide roller assembly 4, so that the end of the steel belt is inserted between the roller groups 42 of the guide roller assembly 4, in the embodiment, the mechanical passive locking of the conveying roller 34 can be realized through the locking mechanism 7, to avoid the situation that there is a misoperation in actual use, so that the conveying roller 34 does not stretch out of the first clamping plate 331 when the flattening mechanism 3 is in the inclined state, although the conveying roller 34 may press the spring 74 to shrink and apply pressure to the steel belt under the influence of gravity, because the weight of the conveying roller 34 is small, the gravity alone cannot cause the concave defect on the surface of the steel belt.

[0048] The above-described embodiments only express several embodiments of the present application, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which belong to the protection scope of the present application.
