Description

Technical Field

[0001] The utility model belongs to the technical field of plate shearing machines, and particularly relates to a positioning device for steel plate shearing machines. Background Art

[0002] Steel shearing machine is a mechanical device used to cut metal plates. It uses the relative movement of two upper and lower blades to perform linear shearing on the steel plates. This equipment is widely used in steel mills, metal processing workshops and steel warehouses. It can handle metal plates of different thicknesses, from thin plates to thicker plates. The positioning device of the steel shearing machine is a key component to ensure cutting accuracy. It helps the operator to correctly place the plate so that it can be cut according to the predetermined size. The positioning device usually includes a front stopper, a rear stopper and an upper stopper, which are used to fix the front and rear positions and the upper end of the plate to ensure that the cutting size is accurate. The existing positioning device for steel shearing machines can only position the front and rear sides and the upper end of the steel, but cannot position the right side of the steel, which may bring the disadvantage of limited cutting accuracy.

[0003] For example, the utility model with announcement number CN220006182U discloses a positioning device for a shearing machine. In this patent scheme, it can only position the front and rear sides and the upper end of the steel, but cannot position the right side of the steel. The lack of right-side positioning causes the plate to shift during the cutting process, affecting the verticality and dimensional accuracy of the cutting edge. The operator may need more time to manually adjust and align the plate, especially when continuously processing plates of different sizes, which will reduce the overall production efficiency. Inaccurate positioning may cause the plate to slide during operation, increasing operational risks. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide a positioning device for a steel shearing machine, which can comprehensively position the front and back sides, the upper end and the right side of the steel, ensuring that each cutting can achieve extremely high dimensional accuracy, reduce errors, reduce adjustment time, and improve production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a positioning device for a steel shearing machine, including a rectangular plate, a placing plate is arranged at the upper end of the rectangular plate, two connecting positioning plates corresponding to the front and rear positions are slidingly arranged inside the rectangular plate, a driving mechanism for driving the connecting positioning plates to move is arranged at the lower ends of the two connecting positioning plates, a right positioning mechanism is arranged between the two connecting positioning plates, and a downward pressing positioning mechanism is arranged on the opposite outer sides of the two connecting positioning plates, the driving mechanism includes four rotating seats respectively slidably arranged at the lower ends of the two connecting positioning plates, connecting frames are rotatably arranged inside the four rotating seats, the middle parts of the two adjacent connecting frames on the left and right are rotatably connected by a pin shaft, two rotating frames are slidably connected to the bottom wall of the rectangular plate, and the ends of the four connecting frames away from the rotating seats are respectively rotatably connected to the adjacent rotating frames, and the lower end of the rectangular plate Two rectangular blocks are provided, and screw rods are rotatably provided inside the two rectangular blocks. The left and right thread directions of the two screw rods are opposite, and the two rotating frames are respectively threadedly connected to the left and right corresponding ends of the screw rods. An electric drive unit for driving the screw rods to rotate is provided at the lower end of the rectangular plate, and the electric drive unit includes a double-axis motor arranged at the lower end of the rectangular plate, and the output shafts on the left and right sides of the double-axis motor are respectively connected to the relative inner ends of the two screw rods through couplings, and the right positioning mechanism includes a connecting plate slidably arranged between the two connecting positioning plates, an electric push rod 1 is arranged on the right side of the connecting plate, and a right positioning plate is arranged on the telescopic end of the electric push rod 1, and the downward positioning mechanism includes four frame plates respectively arranged on the opposite outer sides of the two connecting positioning plates, and the upper ends of the four frame plates are respectively provided with electric push rod 2, and a lower positioning plate is respectively arranged between the telescopic ends of the electric push rod 2 on the left and right sides.

[0006] As a further improvement of the utility model, a control panel is arranged on the front side of the rectangular plate, and the dual-axis motor, the electric push rod 1 and the electric push rod 2 are all electrically connected to the control panel.

[0007] As a further improvement of the present invention, two mounting plates corresponding to left and right positions are arranged at the lower end of the rectangular plate, and two mounting holes are provided inside the two mounting plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by placing the steel plate that needs to be positioned and sheared on the placement plate, and then controlling the dual-axis motor to start, the output shaft rotates to drive the screw rods on both sides to rotate. Since the screw rods on both sides have opposite threads, the rotating frames on both sides are close to each other, and the connecting frame on the rotating frame is rotated and folded and contracted with the central pin shaft, so that the rotating seat slides inside the connecting positioning plate, driving the connecting positioning plates on both sides to approach each other, and the front and rear sides of the steel can be quickly positioned.

[0010] Secondly, by controlling the opening of the second electric push rod, the telescopic end drives the lower positioning plate to move downward, which can quickly realize the positioning of the upper end of the steel.

[0011] Thirdly, by controlling the electric push rod to open and run, the telescopic end drives the right positioning plate to move to the left and contact the right end of the steel, which can quickly realize the positioning of the right end of the steel, and can comprehensively position the front and back sides, upper end and right side of the steel, ensuring that each cutting can achieve extremely high dimensional accuracy, reduce errors, reduce adjustment time, and improve production efficiency.

[0012] Fourthly, the positioning device can be quickly installed on the steel shearing machine through the mounting holes on the mounting plate, making it easy for personnel to install. BRIEF DESCRIPTION OF THE DRAWINGS
