A punching test machine

Abstract

The invention discloses a punching testing machine. The punching testing machine comprises a base, two side support shells, a top cover, an operation platform, a traction machine, a fixed top plate, adirected pulley, a guiding pulley, a traction rope and an impaction head, wherein the fixed column is arranged in the middle of the top surface of the impaction head, the top surface of the fixed column is fixedly connected to one end of the traction rope, and the other end of the traction rope sequentially penetrates through the top plate, the directed pulley and the guiding pulley and is connected to the traction machine; two clamping devices are arranged in the middle of the top surface of the base, rolling guide shoes are respectively fixedly connected to the top surface and bottom surface, close to the support shells, of the impaction head, guide rails are inserted into the rolling guide shoes on the same side and are located in the support shells, two ends of the guide rails are respectively fixedly connected with the top surface of the base and the bottom surface of the fixed top plate, and two locking devices are arranged in the middle of the bottom surface of the fixed top plate; and two same accumulating cavities are symmetrically formed in the top surface of the impaction head, and a plurality of same weighting blocks are placed in the accumulating cavities. The punching testing machine has the beneficial effects that the friction resistance is small, and the impaction testing precision is increased.

Description

technical field [0001] The invention relates to the technical field of stamping test equipment, in particular to a stamping test machine. Background technique [0002] The impact testing machine, as the name suggests, is a material testing machine for applying impact test force to the sample for impact testing. The impact head of the existing impact testing machine has no limit, the impact head falls freely, impacts the material, and the impact force is prone to offset, resulting in errors in the test data; The momentum during the fall is unstable and uncertain, which seriously affects the accuracy of the test. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the problems in the related art, the present invention proposes a stamping testing machine to overcome the above-mentioned technical problems existing in the related art. [0005] Technical scheme of the present in...

AI Technical Summary

Problems solved by technology

The impact head of the existing impact testing machine has no limit, the impact head falls freely, impacts the material, and the impact force is prone to offset, resulting in errors in the test data; some are equipped with a chute limit, but the friction is too large, so that the impact head The momentum when falling is unstable and uncertain, which seriously affects the test accuracy
