Description

Technical Field

[0001] This utility model relates to the field of steel plate forming, and in particular to a feeding rack 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 coiled into rolls. During use, a crane is used to install the entire roll of steel strip onto an automatic uncoiling machine. After the uncoiling machine unwinds the steel strip, it is pulled between the two forming rollers of the forming roller assembly on the forming machine. The rotation of the upper and lower forming rollers shapes the steel strip while simultaneously outputting it to the output end of the forming machine. However, there is a certain distance between the uncoiling machine and the forming machine, and the uncoiling machine rotates at a relatively high speed. The very end of the roll, after exiting the uncoiling machine, generates a huge throwing force, making it easy for workers to be injured by the steel strip. Furthermore, when the uncoiling machine runs out of steel strip output, a crane is needed to load a new roll, which takes time. Therefore, the forming machine must be stopped for a considerable period before it can be used again.

[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

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The aforementioned frame has vertical frames and lower frames. Several lower frames are provided, arranged at intervals along the left and right direction. Two vertical frames are provided, each consisting of a grid panel. The two vertical frames are fixed to the lower frames at intervals, facing each other front to back. The two vertical frames and the lower frames form a hollow space with open bottom, top, left side, and right side. This hollow space is the aforementioned accommodating space. Several vertically arranged baffles are fixed to the opposing front and back surfaces of the two vertical frames, arranged at intervals along the left and right direction. The vertical frames and baffles constitute the aforementioned baffles. Between the two vertical frames, there are several support bars installed between the two baffles, lying horizontally in the front and back direction. These support bars are arranged at intervals left and right, and each support bar constitutes the aforementioned material-blocking structure.

[0008] The upper left side of the two vertical frames is integrally formed with a side wing frame. The left sides of the two wings are connected together by a horizontal seat, and an installation space is formed between the two wings. The upper guide roller and the lower guide roller lie horizontally in the installation space along the front-back direction.

[0018] Figure 3 This is a schematic diagram of the guide wheel device in this utility model. Detailed Implementation

[0019] This utility model relates to a feeding rack for a cold-bending steel forming machine, such as... Figure 1-2 As shown,

[0020] The accommodating space has an upper guide roller 2 and a lower guide roller 3 arranged opposite each other on the left side. The upper guide roller 2 is rotatably mounted on the upright frame 1. The upright frame 1 is equipped with a rotation drive device that drives the upper guide roller to rotate. The lower guide roller 3 is mounted on the upright frame in a way that allows it to move up and down. The upper right side of the upright frame 1 is provided with an upper winding wheel structure for guiding the steel strip through, and the lower right side of the upright frame is provided with a lower winding wheel structure for the steel strip to pass around.

[0021] Specifically, a side wing 121 is integrally formed on the upper left side of the two vertical frame bodies 12. The left sides of the two wing bodies 121 are connected together by a horizontal seat 122, forming an installation space between the two wing bodies. The side wing bodies and the horizontal seat are both composed of several rods, forming a channel for the steel strip to pass through. The upper guide roller and the lower guide roller lie horizontally in the installation space along the front-back direction. That is, an installation frame 123 is provided in the installation space. The installation frame 123 has a base plate and two side plates that stand upright on the base plate and are opposite each other front to back. The base plate is an L-shaped plate with vertical and horizontal parts. The two side plates are fixed to the horizontal part of the base plate. The vertical part is fitted with the left side wall of the two vertical frame bodies and is locked to the vertical frame bodies by screws. A lifting drive device is installed on the base plate below the lower guide roller and drives the lower guide roller 3 to move up and down. The front and rear ends of the upper guide roller 2 are rotatably mounted on the two side plates through bearings.

[0022] The side plate has vertically extending strip-shaped holes 100. Sliding blocks 4, which slide in conjunction with the side plate, are installed within these holes 100. The two ends of the lower guide roller 3 extend into the two sliding blocks 4 and are fixedly installed. The bottom surfaces of the two sliding blocks 4 have vertical connecting posts 41. The two connecting posts 41 are connected together by a horizontal connecting rod 42 located below the lower guide roller 3. A lifting drive device is located below the horizontal connecting rod 42, and its output end is connected to the horizontal connecting rod 42. Preferably, the lifting drive device is a cylinder 5, which is vertically installed on the bottom surface of the base plate. The output end (piston rod) of the cylinder 5 passes upward through the horizontal part of the base plate and is fixedly connected to the horizontal connecting rod 42. In this embodiment, two cylinders 5 are preferably used, arranged at a distance from each other. In application, the two cylinders 5 can be used to push the horizontal connecting rod 42 to move up and down. The up and down movement of the horizontal connecting rod 42 causes the sliding block 4 to slide in the vertical direction within the strip hole 100, thereby realizing the up and down movement of the lower guide roller 3. The distance between the upper guide roller and the lower guide roller can be adjusted by the translation of the lower guide roller 3, so as to convey steel strips of different thicknesses.

[0023] A drive motor 6 is mounted on the top left side of the upright frame 1. The drive motor 6 lies horizontally on the top surface of the upright frame 1 in the front-to-back direction, with its output shaft facing forward. A drive sprocket (not shown in the figure) is fitted over the output shaft of the drive motor 6. The front end of the upper guide roller 2 extends beyond the side plate on the front side, and a driven sprocket (not shown in the figure) is fitted over the front end of the upper guide roller 2 on the same side as the drive sprocket. The drive sprocket and the driven sprocket are driven by a transmission chain. The drive motor, drive sprocket, driven sprocket, and transmission chain constitute the aforementioned rotation drive device. In application, the drive motor 6 is started, causing the upper guide roller 2 to rotate via the drive sprocket, transmission chain, and driven sprocket. The rotation of the upper guide roller 2 conveys the steel strip.

[0024] A left winding wheel 71 for the steel strip to pass over is installed on the right side of the top surface of the upright frame 1. A right winding wheel 72 for the steel strip to pass over and located below the right side of the left winding wheel is installed on the upper right side of the accommodating space. Two upper winding wheels 73 are installed on the right side of the top surface of the upright frame, located outside the right side of the right winding wheel and spaced vertically. The distance between the two upper winding wheels matches the thickness of the steel strip. The left winding wheel, the right winding wheel, and the two upper winding wheels constitute the upper winding wheel structure. The upper winding wheels can be installed in a way that allows for vertical adjustment. The installation method of the left winding wheel, the right winding wheel, and the upper winding wheels adopts the current mounting seat and bearing cooperation method, which is a known technology. A right rod 74 with a distance between it and the upright frame and horizontally arranged front and back is installed on the right side wall of the upright frame 1. A lower winding wheel 75 located below the right rod and for the steel strip to pass over upward is installed. The right rod and the lower winding wheel constitute the lower winding wheel structure. The right rod and lower pulley are also installed using a mounting base and bearing assembly. Specifically, each end of the rod or pulley has a base fixed to the support frame 1, and the ends of the rod or pulley extend into the base via bearings. There is a gap between the right rod and the right side wall of the support frame, and a limiting groove is recessed on the surface of the lower pulley to accommodate the steel belt. During use, the limiting groove ensures that the steel belt exits the lower pulley within the groove, guaranteeing a straight output.

[0025] This utility model discloses a feeding rack for a cold-formed steel profile forming machine, positioned between an uncoiling machine and a forming machine. The uncoiling machine is located on the left side of the feeding rack. The steel strip uncoiled by the uncoiling machine extends between the upper guide roller 2 and the lower guide wheel 3. The rotation of the upper guide wheel 2 pulls the uncoiled steel strip into the receiving space. At this time, the steel strip falls directly into the receiving space due to its own gravity. Meanwhile, the forming machine on the right side pulls the steel strip at a speed lower than the uncoiling speed of the uncoiling machine, resulting in an irregular shape for the steel strip. The steel belt is housed in the receiving space and the support bar 14 is used to prevent the steel belt from falling out of the receiving space. Finally, the first end of the steel belt is pulled upward out of the receiving space, passes upward around the left winding wheel 71 and then pulled upward to the right winding wheel 72. From the right winding wheel 72, it winds upward and extends upward out of the receiving space. Then it passes through the gap between the two upper winding wheels 73. After passing through, it extends downward through the gap between the right rod and the right side wall of the upright, and then extends downward to the lower winding wheel 75. From the lower winding wheel 75, it is output to the right in parallel. Compared to existing technologies, this feeding rack allows the entire steel strip to be placed in a zigzag pattern within the accommodating space. This results in a large storage capacity of steel strip within the accommodating space. After the uncoiling machine finishes uncoiling, the steel strip in the accommodating space can still supply the forming machine with the production needs, eliminating the need for the uncoiling machine to stop and wait. Once the steel strip in the accommodating space is used up, the uncoiling machine will have more steel strip stored in the accommodating space. Workers only need to pull the first end of the steel strip from the accommodating space onto the forming machine for further processing. This significantly reduces the overall downtime of the forming machine, eliminating the need to wait for the steel coil to be placed on the uncoiling machine, thus greatly improving overall work efficiency. Furthermore, the up-and-down movement of the lower guide rollers allows for the conveying of steel strips of different thicknesses, making it widely applicable and flexible in use. The section of the steel strip between the uncoiling machine and the forming machine is not in a straight state. Because of the large amount of steel strip stored in the accommodating space after uncoiling, the swaying force of the steel strip is smaller, and the swaying range of the steel strip end is less, reducing the risk of worker injury.

[0026] In this invention, preferably, a guide wheel device for guiding and conveying the steel belt is installed on the horizontal seat 122. Specifically, a wheel frame 124 is installed on the horizontal seat 122. The wheel frame preferably consists of an upper plate, a lower plate, a front plate, and a rear plate. The wheel frame 124 has two horizontally aligned guide wheels 125 and two vertically aligned guide wheels 126. The two horizontal guide wheels 125 are horizontally aligned and located to the left of the vertical guide wheels 126. The ends of the two horizontal guide wheels 125 are rotatably mounted on the front and rear plates, respectively. There is a passage gap between the two horizontal guide wheels 125 for the steel belt to pass through. The two vertical guide wheels 126 are located to the right of the horizontal guide wheels and have a lateral passage gap between them. The spacing and accommodating space are interconnected. The end of the vertical guide wheel 126 has a vertically installed wheel rod 1261. The upper and lower plates of the wheel frame have strip-shaped holes for the wheel rod to extend into and move back and forth. The wheel rod 1261 has an extension rod 127 that lies horizontally in the front-back direction and extends out of the strip-shaped hole. A nut is screwed onto the part of the extension rod 127 outside the wheel frame and locked to the wheel frame 124 by the nut. The two horizontal guide wheels and the two vertical guide wheels constitute the guide wheel device. In application, the horizontal guide wheel 125 makes it difficult for the steel belt to shift when it is input into the accommodating space. The two vertical guide wheels 126 ensure that the steel belt will not bend. The spacing between the two vertical wheels 12 can be adjusted by the cooperation of the wheel rod, the extension rod and the nut, so as to adapt to the limiting of steel belts of different widths and have a wide range of applications.
