Metal fixture cooling device

Abstract

The invention provides a metal fixture cooling device which comprises a cooling tank and a partition plate. A water injection pipe and an anti-overflow pipe are connected to one side wall of the cooling tank; a water drainage pipe is connected onto the opposite side wall of the cooling tank; an anti-overflow valve is arranged on the anti-overflow pipe; a drain valve is arranged on the drain pipe; the anti-overflow pipe and the drain pipe are positioned on one same horizontal line; the partition plate is arranged in a cooling disc and divides the space in the cooling tank into an anti-overflow area communicated with the water injection pipe and the anti-overflow pipe and a cooling area communicated with the water drain pipe; a water inlet hole is formed in the bottom of the partition plate; and the drain pipe is communicated with the anti-overflow pipe. The metal fixture cooling device provided by the invention can quickly and efficiently cool a metal fixture of an artificial board universal testing machine, and can effectively prevent a board from being wetted to influence the testing effect.

Description

technical field [0001] The invention belongs to the technical field of performance testing of man-made boards, in particular to a cooling device used for rapid cooling of metal jigs used for testing. Background technique [0002] At present, the use of pure wood boards has become less and less, replaced by various man-made boards. The characteristics and scope of use of these wood-based panels are different, and there are many types. Commonly used decorative wood-based panels such as plywood, particle board, fiberboard, polyboard, fireproof board, etc., their physical and chemical properties are important product properties. It is a must-check item in the control. [0003] The test methods for surface bonding strength and internal bonding strength of wood-based panels are mainly based on GB / T17657-2013 test methods for physical and chemical properties of wood-based panels and decorative wood-based panels. When making the test sample, it is necessary to bond the chuck head ...

AI Technical Summary

Problems solved by technology

When making the test sample, it is necessary to bond the chuck of the fixture and the surface of the test sample with hot melt adhesive under high temperature conditions, and then wait for the sample to cool completely to ensure that the bond is firm before proceeding to the test sample. Test, otherwise weak bonding will lead to inaccurate or even invalid experimental results

[0004] However, natural cooling takes a long time and the test efficiency is low
