Description

Technical Field

[0001] The utility model relates to the technical field of shearing tooling, in particular to a tooling for automatically finding a shearing gap when shearing steel plates. Background Art

[0002] Steel plates are widely used in daily life, including various distribution boxes, distribution cabinet shells, and commonly used metal products. All of them require shearing, punching, bending, welding, assembly and other processes to complete. The shearing in steel plate processing is done by two shear blades in linear motion, curved motion or circular motion to cut the rolled piece.

[0003] A search revealed Chinese patent publication (announcement) number CN207343876U, which discloses a steel plate shearing device comprising a cutter base and two upright posts, each of which is connected to a crossbeam at the top. The cutter base is positioned between the two upright posts, and a telescopic rod is provided between the crossbeam and the cutter base. The telescopic rod is provided with two pins, each of which is connected to an upper swing arm and a lower swing arm. The upper end of the upper swing arm is hinged to the crossbeam, and the lower end of the lower swing arm is hinged to the cutter base. A pressure plate and two buffer cylinders are also provided on the back of the cutter base. Each buffer cylinder contains a first spring, and the lower ends of the two first springs are connected to the pressure plate via connecting rods. A cutter is provided at the bottom of the cutter base, with the lower end of the cutter being above the lower end of the pressure plate. This utility model reduces the force required to shear steel plates and reduces energy consumption. Since there is a pressing plate, and the lower end of the pressing plate is lower than the lower end of the cutter, the pressing plate will press the steel plate first, and the cutter will come later. Therefore, even for the end of a shorter steel plate, it can be cut conveniently without causing waste.

[0004] Although the above patent can fix the steel plate, it does not have the function of automatically adjusting the gap according to the thickness of the plate. During the shearing process, since the steel plates to be sheared have different thicknesses, the gap between the upper cutting die and the lower cutting die is prone to change, affecting the accuracy of steel plate shearing and the quality of the finished product. Therefore, it is necessary to design a tooling for automatically finding the shearing gap for steel plate shearing to solve the above problem. Utility Model Content

As the support plate 3 moves, the pressure block 19 presses the steel plate to maintain stability during cutting. The second spring 18 enables the pressure block 19 to adapt to the use of steel plates of different thicknesses. The upper cutter 5 and the lower cutter 23 cooperate with each other to ensure the neatness of the incision during cutting. After the steel plate shearing is completed, the hydraulic rod 2 is reset. At the same time, under the elastic action of the first spring 17, the gasket 16 drives the connecting rod 7 to reset, thereby providing convenience for the next use of the thickness detector probe 8.
