Impact-resistant energy absorption testing machine for protective gloves

Abstract

The invention relates to the technical field of protective glove detection, and concretely relates to an impact-resistant energy absorption testing machine for protective gloves. The testing machine comprises a rack, an impact device, an up-down moving mechanism, an energy testing device and a catching device. The rack comprises a bottom plate, side plates, a back plate and a vertical plate; the vertical plate moves in the X-axis direction relative to the back plate; the side plates move in the Y-axis direction relative to the bottom plate; the up-down moving mechanism moves in the Z-axis direction relative to the vertical plate; the impact device comprises a punch and an electromagnetic chuck arranged at the upper part of the punch; the energy testing device comprises a test fixture plate arranged at the upper part of the bottom plate and a sample lower die arranged on the test fixture plate; and the catching device comprises a catcher capable of conducting opening and closing actions and a control assembly used for controlling the catcher to act. According to the invention, secondary impact of the punch can be prevented, and the test accuracy and the machine safety are improved; and X-axis, Y-axis and Z-axis movement can be achieved, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of detection of labor anti-shock products, in particular to a testing machine for impact resistance energy absorption of protective gloves. Background technique [0002] The impact strength test of plastic, ceramics, acrylic, glass, lens, hardware and other products generally adopts punch impact testing machine. The punch impact testing machine puts the test product on the test table, freely drops the punch of the specified weight on the product from the specified drop height, impacts the product, and then checks the appearance and performance of the product. In order to verify whether the performance of the test product complies with relevant international and national safety standards. [0003] But in actual use, after the free fall of the punch impacts the test product, it will give the punch a reaction force, and the jump of the punch will cause a secondary impact on the test product, resulting in inacc...

Problems solved by technology

[0003] But in actual use, after the free fall of the punch impacts the test product, it will give the punch a reaction force, and the jump of the punch will cause a secondary impact on the test product, resulting in inaccurate test data and affecting the overall test results.

Moreover, the total weight of the punch is relatively heavy, and the punch jumps, which poses a certain safety hazard for the machine and the operator.

[0004] Most of the current impact strength testing machines simply move up and down in the direction of the Z axis, and cannot move the X, Y, and Z axes at the same time. Useful for actual production testing
