Description

Technical Field

[0001] The utility model relates to a shearing machine, in particular to a straightening and fixing shearing device of a steel belt shearing machine. Background Art

[0002] Steel strip is a kind of steel material with large output, wide application and many varieties. At present, in order to facilitate the production and transportation of steel strip, it is generally made into steel coils. When in use, the steel strip is straightened and cut into fixed lengths. Then, the longer steel strip raw materials are cut to fixed lengths according to demand to obtain narrow and long steel strips of the same length. For the cutting of narrow and long steel strips, the existing method is generally to cut the steel strips manually or on a fixed cutting tool. Since the steel strips are long and easy to bend, it is difficult to straighten them manually, so it is difficult to accurately cut the specified length; and the shape of the cuts after cutting is inconsistent, which may cause the steel strips to rebound at the moment of cutting and injure the workers.

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a straightening and fixing shearing device for a steel strip shearing machine, which includes a machine base 101 and a support platform 102 arranged on the machine base, a lower cutter 103 is installed on the support platform, a column 104 is provided at the rear of the support platform, a cylinder mounting plate 105 is connected to the top of the column, a shearing cylinder 107 for driving an upper cutter 106 is installed on the cylinder mounting plate, and a buffer three-axis cylinder 108 is provided on one side of the support platform and is installed on the cylinder mounting plate. When the buffer three-axis cylinder drives the rubber-coated wheel 109 to press the steel strip 1 placed on the support platform, the shearing cylinder drives the upper cutter to move downward to cut the steel strip on the lower cutter. During the implementation process, the telescopic shaft of the buffer three-axis cylinder is fixedly connected to the buffer seat 110, and the rubber-coated wheel is installed on the buffer seat, so that the buffer three-axis cylinder drives the rubber-coated wheel to move up and down through the buffer seat. When the buffer three-axis cylinder drives the rubber-coated wheel to press the product, the axial force generated by the upper cutter shearing the product will be absorbed by the soft rubber jacket of the rubber-coated wheel without affecting the buffer three-axis cylinder. This not only avoids the rebound of the steel belt and improves safety, but also avoids crooked cutting, ensures consistent incision shape, and improves product quality.

[0021] Preferably, a straightening mechanism 12 capable of straightening the steel strip is provided on the other side of the support platform to ensure that the steel strip can be cut to a specified length. Specifically, the straightening mechanism 12 includes a cylinder seat 121 arranged on the machine base 101, a straightening cylinder 122 horizontally installed on the cylinder seat, a straightening platform 13 driven to move by the straightening cylinder, and a pressing cylinder 123 vertically arranged on the straightening platform. The pressing cylinder drives the pressing plate 14 to move. When the steel strip is placed on the straightening platform, the pressing cylinder drives the pressing plate to press the steel strip on the straightening platform, and then the straightening cylinder drives the straightening platform to move to straighten the steel strip, thereby avoiding the product bending downward due to excessive length after the steel strip is pulled to the specified length, and ensuring the accurate cutting length of the steel strip.

[0022] During the implementation process, the telescopic shaft of the straightening cylinder is connected to the straightening platform through a flexible joint 124, such as being hinged through a flexible joint such as a coupling, so as to avoid a rigid connection and ensure the stability of the straightening platform driven by the straightening cylinder. The straightening platform 13 includes a vertically arranged side plate 131, a platform plate 132 arranged at the upper end of one side of the side plate, and a seat plate 133 arranged at the lower end of the other side of the side plate. The flexible joint is connected to the seat plate, the pressing cylinder is installed on the seat plate, and the steel belt is placed on the platform plate. The side plate, the platform plate, and the seat plate are connected to form an integral structure, and the straightening cylinder drives the integral structure to move. The pressing plate 14 includes a lower plate 141 connected to the telescopic shaft of the pressing cylinder, an inclined plate 142 connected to the lower plate at the lower end, and an upper plate 143 connected to the upper end of the inclined plate. When the pressing cylinder drives the lower plate to move up and down, the lower plate drives the inclined plate and the upper plate to move up and down. When the upper plate moves downward, the steel strip is pressed between the upper plate and the platform plate, which is beneficial to straightening on the one hand, and on the other hand, the steel strip can be firmly limited by cooperating with the rubber-coated wheel on the other side of the upper cutter to avoid crooked cutting and ensure consistent incision shape.

[0023] Preferably, a linear guide rail 125 is provided on the machine base 101, and a linear slider 126 is provided on the lower side of the seat plate, and the straightening cylinder drives the linear slider to move along the linear guide rail through the seat plate. Therefore, after the clamping cylinder drives the upper plate to clamp the steel strip, the straightening platform is pulled together with the clamping cylinder by the retraction of the straightening cylinder to ensure that the steel strip is straightened. The telescopic shaft of the shearing cylinder is connected to a guide block 111, and a knife seat 112 for mounting the upper cutter is connected to the guide block, which is conducive to setting the knife seat and convenient for replacing the upper cutter. A Z-direction slider 113 is connected to one side of the guide block, and a Z-direction guide rail 114 is provided on the column. The shearing cylinder drives the Z-direction slider to move along the Z-direction guide rail through the guide block to prevent the upper cutter from shaking when it descends for shearing, thereby ensuring the accuracy of shearing.

[0024] The upper side of the straightening cylinder of the utility model is provided with a cylinder cover 127 to protect the straightening cylinder; the cylinder cover is provided with an adjustable limit groove 128 for placing the steel strip, and the limit groove can be made of two sheet metals arranged in parallel on the cylinder cover, and the sheet metal is fixed by setting a strip hole on the cylinder cover and bolts, and the position of the limit groove is adjusted by fixing it at different positions of the strip hole to ensure that the steel strip is limited to a straight state. Preferably, the side wall of the support platform 102 is provided with an adjustment plate 115 that can limit the steel strip. Two adjustment plates are used, and part of them protrudes from the support platform, and the steel strip is clamped between the two adjustment plates by the protruding part to achieve the positioning of the steel strip. In the implementation process, a strip hole and a bolt can also be set to cooperate with the fixing adjustment plate to adjust the width of the two adjustment plates according to the size of the steel strip, so as to limit the steel strip more accurately. The utility model firmly limits the steel strip by limiting it at two places and pressing it at two places, which greatly improves the accuracy of shearing.
