Example Embodiment

[0012] Example: figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, this embodiment includes a frame 1, which is provided with a shearing mechanism, a pressing device, a material blocking device, a material support frame 6, a cutting edge gap adjustment device 10, and a hydraulic oil tank 9. The frame 2 is The steel plate welded frame structure includes left vertical plate, right vertical plate, front pressure plate, and workbench. ;

[0013] The shearing mechanism includes a tool holder 2, two hydraulic cylinders 7 and 8, and a blade clearance adjustment device 10. The tool holder 2 is a triangular section welding structure. On the frame 1, the lower shearing blade 5 is installed at the position corresponding to the upper shearing blade 11. The tool holder is guided by a three-point clamping type rolling guide, and is inclined forward by 1.5 degrees. The ends of the piston rods of the hydraulic cylinders 7 and 8 are connected to The tool holder is connecte...

Abstract

The invention relates to a strip steel specimen shearing device which comprises a rack. A shearing mechanism, a press device, a stop device, a supporting bracket, an edge clearance adjusting device and a hydraulic tank are arranged on the rack; a feeding ball is arranged on the supporting bracket; the shearing mechanism comprises a cutter holder, two hydraulic cylinders and an edge clearance adjusting device; an upper shearing edge is installed on the cutter holder; a lower shearing edge is installed in the position corresponding to the upper shearing edge on the rack; the end parts of piston rods of the hydraulic cylinders are connected with the cutter holder by connection rods; the hydraulic cylinders drive the cutter holder to make up-and-down movement and downward movement to complete the shearing action; the press device is arranged in front of the shearing edges; the press device comprises a pressing cylinder and a pressing head; the pressing head is connected with the pressing cylinder; and the pressing cylinder is installed on the rack. The cutter holder can rotate around the rotating shaft of the cutter holder by 0-4 degrees, and can shear special steel and common steel specimens into laboratory-use specimens. The tensile strength of the shorn steel is max.830MPa, the yield strength is max.630MPa, and the service life is longer.

Description

Technical field: [0001] The invention belongs to a shearing machine, in particular to a strip steel sample shearing device. Background technique: [0002] The sampling device for hot-rolled strip steel and cold-rolled strip steel currently uses QA11Y-40×2500 sample shears, which often have shear angle deviations during application, causing the sheared samples to be distorted and unqualified, and often occur due to The steel type does not match the shear parameters, resulting in a high failure rate of shear blade cracking. Invention content: [0003] The invention aims to provide a strip steel sample shearing device with a high pass rate of the shear sample. [0004] The technical solution for realizing the present invention is: comprising a frame, the frame is provided with a shearing mechanism, a pressing device, a material retaining device, a material holder, a cutting edge gap adjustment device, and a hydraulic oil tank, and the frame is characterized in that the frame...
