CN2864661Y - Cold bending testing head for material testing machine - Google Patents

Abstract

Disclosed is a cold-bending testing pressure head of material tester, pertaining to the mechanical technology field, and is characterized in that the top of U-shaped pressure head shelf is fixed and connected with bolts, the edge within the pressure head shelf is provided with V-shaped groove, the outer edge of the pressure head flashboard is convex chamfering V shape and the pressure head flashboard can fixed matching with the pressure head shelf. Its beneficial effects are: different pressure head flashboards to be replaced can meet the cold-bending test of the metal materials with all specifications, and the test results of samples both on the force face, a formed 180-degree angle and concentricity and etc have met the requirements of design and standards of all countries.

Description

Material Testing Machine clod wash testing pressure head

Technical field

The utility model belongs to field of mechanical technique.

Background technology

Present Material Testing Machine, though be mechanical, or its fall head of hydraulic pressure mostly is the 40-60 millimeter greatly, the flexual center diameter only has few in number several of 30 millimeters of 20 millimeters of Φ, Φ, owing to be subjected to fall head and single flexual center diameter restrictions, make the cold bend test of metal material, can only be confined in certain test specification.And the import and export metal material that needs check is wide in variety, specification assorted, does not only satisfy the requirement of test far away with conventional pick-up unit.

Summary of the invention

The purpose of this utility model is:

A kind of Material Testing Machine clod wash testing pressure head is provided, and it can fast, accurately carry out the cold bend test of the metal bar of all size.

The technical solution of the utility model is:

Be fixed with coupling bolt in U-shaped pressure head frame upper end, pressure head frame inward flange has V-shaped groove, and pressure head plate outward flange is a fin V-arrangement shape, and the pressure head plate can be pegged graft to cooperate and be fixed with the pressure head frame.

The beneficial effects of the utility model are:

By changing different pressure head plates, can satisfy the cold bend test of all size metal material, no matter be stress surface, the one-time formed angle of 180 degree to the sample testing result, and concentricity etc. has all reached the requirement of design and various countries' standard code.
