A rubber wear-resistant test equipment for plastic products

Abstract

The invention discloses a rubber wear-resisting test equipment for plastic products, which comprises a test table, on which a test board is movable left and right, and the test board is connected with the test table through an electric slide rail; it is used for positioning workpieces. The positioning clamping device is set on the test table; the friction device is located above the clamping device and is used for friction testing the surface of the workpiece to be tested; the pressure device is used to apply different degrees of pressure to the friction device; The liquid storage cylinder at the upper end of the moving column, the columnar liquid storage cavity arranged in the liquid storage cylinder, and the liquid inlet connected to the liquid storage cavity in the upper part of the liquid storage cylinder. The present invention adopts the method of liquid weighting to increase the gravity pressure on the rubber, and converts the final gravity by multiplying the volume of the liquid by the density, so that the magnitude of the gravity change value can be accurate to a smaller degree, the degree of deviation is reduced, and the control accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of plastic product processing, and in particular relates to a rubber wear-resistant test device for plastic products. Background technique [0002] After the plastic products are processed and before leaving the factory, their wear resistance needs to be checked by wear-resistant equipment to ensure that the plastic products have sufficient wear resistance after they are put into use in the later stage. Existing wear-resistant equipment usually uses rubber to quickly rub the surface of plastic products multiple times to test its wear resistance. In the traditional grinding method, in order to ensure sufficient friction between the rubber and the plastic product, weights are added to the column on which the rubber is set. However, in this method, when processing different types of plastic products, it is necessary to manually replace different The work efficiency of the weight is relatively low; and the weig...

In the traditional grinding method, in order to ensure sufficient friction between the rubber and the plastic product, weights are added to the column on which the rubber is set. However, in this method, when processing different types of plastic products, it is necessary to manually replace different Weights, the work efficiency is relatively low; and the weights can only be changed according to their units, which cannot meet more accurate gravity adjustment
