Description

Technical Field

[0001] This utility model relates to the field of steel plate forming, and in particular to a steel plate feeding device for a cold-bending steel forming machine. Background Technology

[0002] The so-called cold bending of steel refers to the steel forming technology that uses a series of forming rollers to form a steel strip with a certain shape and load-bearing capacity.

[0003] In cold bending forming technology, the raw material steel strip is set in a coil, called a steel coil. When using it, the whole coil of steel strip is installed on an automatic uncoiling machine with the assistance of a crane. Some uncoiling machines are self-powered, while others are not. However, regardless of the type of uncoiling machine, a new steel coil needs to be loaded after each steel coil is uncoiled. As a result, the entire forming machine needs to wait for the crane to load the steel coil, which makes the overall processing efficiency low.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned problems, which led to the creation of this invention. Utility Model Content

[0005] The purpose of this utility model is to provide a steel plate loading device for a cold-bending steel forming machine, which solves the problem that the forming machine has to wait for the steel coil to be reloaded by a crane after use before it can be processed again, resulting in low overall processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel plate feeding device for a cold-formed steel equipment forming machine, including an uncoiling machine and a feeding machine. The feeding machine includes a base frame and a mounting frame rotatably mounted on the base frame. The mounting frame has three horizontally spaced support seats, and there is an accommodating space for placing steel strips between each pair of support seats. A rotating shaft is mounted on each pair of support seats, with its two ends rotatably mounted on the two support seats. One end of the rotating shaft has a rotation drive device for driving the rotating shaft to rotate. Each rotating shaft is equipped with two vertically arranged limiting plates that are fitted outside the rotating shaft. The distance between the two limiting plates is the accommodating space. One of the two limiting plates is mounted on the rotating shaft in a manner that allows it to be horizontally adjusted towards the other limiting plate, while the other limiting plate is in a fixed state.

[0007] The aforementioned base frame is equipped with a wheel frame, on which guide wheels are rotatably mounted, horizontally positioned above the top surface of the base frame. The center lines of each guide wheel are all oriented towards the center of the base frame. The bottom surface of the aforementioned mounting frame is in contact with the guide wheels. The aforementioned base frame is equipped with a motor drive device that drives the mounting frame to rotate.

[0008] The aforementioned mounting bracket has a chassis and a frame fixed on the chassis. The chassis has a circular structure. The aforementioned guide wheel is in contact with the bottom surface of the chassis, and the axial length of the guide wheel is greater than the width of the bottom surface of the chassis. The aforementioned frame has a square base frame and three support seats that are respectively erected on the top surface of the square base frame. The horizontal arrangement direction of the three support seats is the left-right direction. The two aforementioned rotating shafts are arranged horizontally to the left and right. The left end of the rotating shaft on the left is rotatably mounted on the leftmost support seat through a bearing, and the right end of the rotating shaft on the right is rotatably mounted on the rightmost support seat through a bearing. Both the leftmost and rightmost support seats are equipped with motor drive mechanisms to drive the rotating shafts to rotate. The right end of the left rotating shaft and the left end of the right rotating shaft are both fitted with guide wheels erected on the support seats. The aforementioned motor drive mechanism is the aforementioned rotation drive device.

[0009] The aforementioned limiting piece is a circular piece.

[0010] The aforementioned rotating shaft is provided with a protruding strip extending along the axial direction of the rotating shaft at the part between the two support seats. The central area of ​​the aforementioned limiting piece is provided with a through hole for the rotating shaft to pass through in a tight fit, and the inner wall of the through hole is provided with a positioning hole for the protruding strip to be inserted through.

[0011] The aforementioned rotating shaft is fitted with a locking nut on the outside of one of its limiting plates, and the locking nut is located between the drive motor and the limiting plate.

[0012] By adopting the above technical solution, the steel plate feeding device of the cold-formed steel equipment forming machine of this utility model allows for the following operation: a steel coil is placed on an uncoiling machine, and the steel strip is pulled out from the uncoiling machine and wound onto a rotating shaft. A rotation drive device drives the rotating shaft to rotate, and the rotation of the rotating shaft allows the steel strip to be wound around the rotating shaft, thus feeding the forming machine. While this rotating shaft is feeding the forming machine, another steel coil is placed on the uncoiling machine, and the steel strip is pulled out and wound onto another rotating shaft. The rotation of this rotating shaft allows the steel strip to be wound around it. Thus, when one rotating shaft is uncoiling and feeding, the other rotating shaft is rewinding. After the first rotating shaft has finished uncoiling, the mounting frame rotates to uncoil the rewinding rotating shaft and then rewind it, allowing the steel strip to be continuously supplied to the forming machine without waiting for the crane to lift the steel strip, greatly improving the forming efficiency.

Figure 1-2As shown, the device includes an unwinding machine (not shown in the figure). This unwinding machine is existing equipment and is not an improvement of this patent application, so it will not be described again here. The steel plate loading device also includes a loading machine, which includes a base frame 1 and a mounting frame 2 rotatably mounted on the base frame. A wheel frame 11 is mounted on the base frame 1, and a guide wheel 3 is rotatably mounted on the wheel frame 11 and is horizontally arranged above the top surface of the base frame 1.

The guide wheel 3 is located between the two plates and is rotatably mounted on the two vertical plates through a wheel axle. The center line of each guide wheel 33 is pointing towards the center line of the wheel frame 11.

[0016] The bottom surface of the mounting frame 2 is in contact with the guide wheel. The mounting frame 2 has three horizontally spaced support seats. There is an accommodating space between each pair of support seats for placing the steel strip. A rotating shaft 4 is mounted on each pair of support seats, with its two ends rotatably mounted on the two support seats. One end of the rotating shaft 4 has a rotation drive device for driving the rotating shaft to rotate. Each rotating shaft is equipped with two vertically arranged limiting plates 5 that are fitted outside the rotating shaft. The distance between the two limiting plates 5 is the accommodating space. One of the two limiting plates 5 is mounted on the rotating shaft in a way that allows it to be adjusted laterally towards the other limiting plate, while the other limiting plate is in a fixed state.

[0017] Preferably, the mounting frame 2 has a chassis 21 and a frame 22 fixed on the chassis. The chassis has a circular structure, and the wheel surfaces of each guide wheel 3 are in contact with the bottom surface of the chassis 21. The axial length of the guide wheel 22 is greater than the width of the bottom surface of the chassis, that is, the two ends of the guide wheel 22 are outside the chassis. The guide wheel 22 makes the rotation of the mounting frame 2 smoother. A vertically set central shaft (not shown in the figure) is provided at the center of the chassis 1. The lower end of the central shaft is rotatably mounted on the chassis 1, and the upper end of the central shaft is fixedly connected to the central area of ​​the chassis 21 through a mounting bearing. A motor drive mechanism that drives the central shaft to rotate is installed on the chassis 1. This motor drive mechanism is existing technology. For example, a combination of a drive motor, a reducer and gears can be used. The output shaft of the drive motor is matched with the reducer. The output shaft of the reducer has a gear. A gear is also sleeved on the outside of the central shaft. The two gears mesh with each other.

[0018] The frame 22 has a square base frame 221 and three uprights 222 respectively standing on the top surface of the square base frame. These uprights 22 are the support seats. Two rotating shafts 4 are arranged horizontally to the left and right. The left end of the rotating shaft on the left is rotatably mounted on the leftmost support seat via a bearing, and the right end of the rotating shaft on the right is rotatably mounted on the rightmost support seat via a bearing. Both the leftmost and rightmost support seats are equipped with motor drive mechanisms to drive the rotating shafts. The right end of the left rotating shaft and the left end of the right rotating shaft are fitted with guide wheels 7 standing on the support seats. The aforementioned motor drive mechanisms are the rotation drive devices. Specifically, with the horizontal arrangement direction of the three support seats as the left-right direction, the three uprights 22 are divided into a first upright, a second upright, and a third upright from left to right. The first and third uprights are triangular frames, and the second upright is a square base. The rotating shaft on the left is the left rotating shaft, and the rotating shaft on the right is the right rotating shaft. The first upright... The top right side of the first stand and the top left side of the third stand are both fitted with bearing seats 223. The left end of the left rotating shaft and the right end of the right rotating shaft are respectively mounted on the two bearing seats through bearings. The top left side of the first stand and the top right side of the third stand are both fitted with motor seats 224. The drive motor mechanism has a drive motor 6 and a planetary reducer. The drive motor can release the steel coil according to the speed of the cold bending steel forming machine to reduce the load on the forming machine and improve the efficiency of the forming machine. The drive motor and the planetary reducer move along the left and right sides. The drive motor 6 is horizontally mounted on the motor base 224, and the output shaft of the drive motor 6 is fixedly connected to the end of the rotating shaft via the bearing housing 223 through the planetary reducer. Guide wheels 7 are fitted on the outer right end of the left rotating shaft and the outer left end of the right rotating shaft. Both guide wheels 7 are located on the top surface of the second stand. A hollow limiting seat is installed on the top surface of the second stand corresponding to the guide wheel 7. The two limiting seats are staggered relative to each other, and the two limiting seats have an open structure on their opposite sides. A part of the guide wheel 7 is located inside the limiting seat.

[0019] The limiting piece 5 is a circular piece. The rotating shaft 4, located between the two support seats, has a protruding strip (not shown in the figure) extending axially along the rotating shaft. A through hole is provided in the center of the limiting piece 5 for the rotating shaft to pass through, and a positioning hole is recessed on the inner wall of the through hole for the protruding strip to be inserted. A locking nut 41 is screwed onto one of the limiting pieces, and the locking nut is positioned between the drive motor and the limiting piece. The limiting piece has an inner ring and an outer ring, connected by several evenly spaced connecting rods. A clamping block is fixed inside the inner ring and fitted onto the rotating shaft. A square through groove extending laterally is provided on the inner diameter of the clamping block. A square strip extending laterally and matching the square through groove is provided on the outer wall of the rotating shaft; this square strip is the aforementioned protruding strip. The groove is the positioning hole. On each rotating shaft, the clamping block of the limiting plate facing the bearing seat 223 has a tightening ring extending towards the bearing seat. The part of the rotating shaft between the limiting plate and the bearing seat 223 has an external thread. The locking nut 41 is screwed onto the outside of the rotating shaft and fits tightly against the tightening ring. The clamping block of the limiting plate facing the guide wheel 7 has a protruding ring extending out of the inner ring body. The outer side wall of the rotating shaft 4 has a limiting ring that fits tightly against the protruding ring. The two limiting plates are located between the limiting ring and the locking nut. In application, the steel strip is clamped between the two limiting plates, and the two limiting plates are clamped between the limiting ring and the locking nut. In this way, the steel strip will not deviate. By loosening the locking nut, and with the guidance of the protruding strip and the positioning hole, the limiting plates can be moved laterally to adjust the distance between the two limiting plates to accommodate the winding of steel strips of different widths.

[0020] This utility model discloses a steel plate feeding device for a cold-formed steel equipment forming machine. In application, a steel coil is placed on an uncoiling machine, and then the steel strip is pulled out from the uncoiling machine and wound onto a left rotating shaft. The drive motor 7 on the first support rotates the left rotating shaft, causing it to coil the steel strip. After coiling, the entire mounting frame 2 rotates 180 degrees, and the steel strip on the left rotating shaft is pulled out to the forming machine for feeding and forming operations. During the feeding and forming operation, a crane then places another steel coil onto the uncoiling machine for further processing. The unwound steel strip is wound onto the right rotating shaft. Thus, the left rotating shaft unwinds while the right rotating shaft rewinds. Once the steel strip on the left rotating shaft is unwound, the mounting frame rotates 180 degrees, and the right rotating shaft unwinds while the left rotating shaft rewinds. This process is repeated, ensuring a continuous supply of steel strip to the forming machine without waiting for a crane to lift the steel strip, greatly improving forming efficiency. Furthermore, the entire structure is simple and easy to operate, and the two limiting plates allow it to accommodate steel strips of different sizes, making it highly adaptable.

[0021] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
