Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a steel plate shearing machine. Background Technology

[0002] With economic development, the application of steel plates has become increasingly widespread. Steel plates are widely used in construction, automobiles, bridges and other fields. In their initial state, steel plates exist as large flat plates for easy transportation. In actual applications, steel plates need to be cut into specific sizes and shapes to facilitate subsequent applications and meet the requirements of various engineering and manufacturing projects.

[0003] Existing steel plate shearing machines are inconvenient for positioning steel plates, causing them to easily shift left and right during cutting, resulting in displacement of the cut plate and affecting processing quality. Furthermore, it is inconvenient to adjust the specific cutting length of the steel plate, making them unconvenient to use. Therefore, it is necessary to propose a steel plate shearing machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a steel plate shearing machine that offers stable cutting and easy adjustment of the cutting length.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel plate shearing machine, including a shearing frame, on which a steel plate anti-deviation component, a pusher component, a shearing component, and a positioning component are provided. The steel plate anti-deviation component includes two clamping plates symmetrically arranged on the shearing frame. Screws are rotatably arranged on both the front and rear side walls of the shearing frame. Threaded sleeves are provided on the screws. Connecting rods for connecting the clamping plates are installed on the threaded sleeves. Guide rods that are slidably connected to the shearing frame are installed at both ends of the clamping plates. A driving component for driving the two screws to rotate is provided at the bottom of the shearing frame.

[0006] By adopting the above technical solution, when cutting steel plates, the drive unit first controls the rotation of the screws on both sides, and with the cooperation of the threaded sleeve and the guide rod, the connecting rod pushes the two clamping plates to move relative to each other, thereby adjusting the distance between the two clamping plates so that they clamp the two sides of the steel plate. When the steel plate is pushed forward and sheared, the steel plate will not shift, and the cutting quality is better.

[0007] A further feature of this invention is that the driving component includes a dual-axis motor mounted on the bottom of the shearing frame, a rotating rod is mounted on the output end of the dual-axis motor, and a linkage gear is mounted between the end of the rotating rod and the end of the screw.

[0008] By adopting the above technical solution, the rotating rods on both sides are driven to rotate relative to each other by a dual-axis motor, and the screw is driven to rotate under the cooperation of the linkage gear, thereby pushing the two clamping plates to move relative to each other.

[0009] A further feature of this invention is that the linkage gear includes a main gear mounted on the end of the rotating rod, and a driven gear meshing with the main gear is mounted on the end of the screw.

[0010] By adopting the above technical solution, when the rotating rod rotates, it drives the main gear at the end to rotate, and through meshing, it drives the driven gear to rotate, thus causing the screw to rotate.

[0011] A further feature of this invention is that the positioning element includes a fixing frame installed on the right end of the shearing frame, a first electric push rod is installed on the right end of the fixing frame, and a baffle is installed on the output end of the first electric push rod.

[0012] By adopting the above technical solution, the first electric push rod pushes the baffle to slide to the left. Before the steel plate is cut, the steel plate moves to the right and its end abuts against the baffle, so that the steel plate is precisely cut.

[0013] A further feature of this invention is that pulleys are installed at both ends of the baffle, and a slide rail adapted to the pulleys is provided on the inner side of the fixing frame.

[0014] By adopting the above technical solution, the movement of the baffle is made more stable through the cooperation of the pulley and the slide.

[0015] A further feature of this invention is that the shearing component includes a bracket mounted on a shearing frame, two second electric actuators are mounted on the bracket, a pressure plate is mounted between the output ends of the two second electric actuators, and a cutter and an elastic clamping component are provided on the pressure plate.

[0016] By adopting the above technical solution, during shearing, the second electric push rod is driven, causing the pressure plate to move the cutter and the elastic clamping component downward as a whole, thereby further pressing the steel plate and shearing the steel plate by the cutter, further improving the accuracy of shearing.

[0017] A further feature of this invention is that the elastic clamping member includes a movable frame mounted on the pressure plate, with springs fitted at both ends of the movable frame and a positioning plate at the bottom.

[0018] By adopting the above technical solution, when the pressure plate moves down, the positioning plate presses down on the upper part of the steel plate, and the spring tension allows the positioning plate to better press the steel plate.

[0019] A further feature of this invention is that the pusher plate includes a drive motor installed on the left end of the shearing frame, a lead screw is installed at the output end of the drive motor, a fixed rod is provided in the inner cavity of the shearing frame below the lead screw, a movable block is slidably connected to the fixed rod on the external thread of the lead screw, and a pusher plate is installed on the movable block.

[0020] By adopting the above technical solution, the drive motor controls the screw to rotate, and under the sliding limit of the fixed rod, it pushes the moving block to translate, so that the push plate pushes the steel plate to move, thereby continuously pushing the steel plate to the shearing position.

[0021] The beneficial effects of this utility model are:

[0022] 1. This utility model uses a dual-axis motor to drive the rotating rods on both sides to rotate relative to each other, and with the cooperation of the linkage gear, it drives the screw to rotate. With the cooperation of the threaded sleeve and the guide rod, the connecting rod pushes the two clamping plates to move relative to each other, thereby adjusting the distance between the two clamping plates so that they clamp the two sides of the steel plate. When the steel plate is pushed forward and sheared, the steel plate will not shift, and the cutting quality is better.

[0023] 2. In this utility model, the first electric push rod pushes the baffle to slide to the left. Before shearing the steel plate, the steel plate moves to the right and its end abuts against the baffle, so that the steel plate is precisely cut. The cutting length can be adjusted flexibly. The drive motor controls the screw to rotate. Under the sliding limit of the fixed rod, the moving block is pushed to move horizontally, so that the push plate pushes the steel plate to move, thereby continuously pushing the steel plate to the shearing position and improving its cutting efficiency.
