Abstract
The invention discloses a kind of Charpy impact machine tester, by frame, pendulum, jaw seat and pendulum hitch are formed, the hammer body of pendulum is a sector structure, which is provided with some and counterweight hole not of uniform size, can realize that free beam impacts and izodtest, raise the angle in advance, can change impact energy and impact velocity by what change pendulum, satisfy the requirement of a plurality of ranges, the suffered windage of sector hammer body is little, and energy loss is little, and can avoid departing from the phenomenon that barycenter causes the hammer stem bending because of striking point, has dismounting, debugging is convenient, rational in infrastructure, cost is low, advantage easy to use, both make things convenient for manufacturing enterprise to use, helped the test that makes a search again.
Description
Technical field
The present invention relates to a kind ofly be carried out one-shot the test unit of absorbed energy when measuring sample and destroying, particularly a kind of Charpy impact machine tester to trying material.
Background technology
Usually measure toughness of material by impulse test in the industrial circle, make one-shot with the pendulum that testing machine lifts, sample is thrust along breach, pendulum rose the absorption merit that difference in height is calculated sample again when usefulness fractureed.At present, Charpy impact machine tester is divided into two kinds of charpy impact test machine and radial-boom impact testers, the hammer body structural similarity of its pendulum, all be that a U type impact block is fixed in a Metallic rod lower end, inlay a V-type in the U type groove of impact block and impact sword, the jaw seat difference of two kinds of testing machines is applicable to freely-supported beam type and beam type respectively, raises the angle angle in advance and is generally 120 °～150 °.The deficiency that existing this Charpy impact machine tester exists mainly shows the following aspects: it is bad fixing that 1, the structure of above-mentioned pendulum hammer body makes the barycenter of hammer, need counterweight repeatedly, guaranteeing barycenter on striking point, otherwise the phenomenon of hammer stem bending can appear in impulse test; 2, machine can not be done the impulse test of multipotency, the impulse test of doing one or two energy that can only fix simultaneously; 3, a machine can only be done freely-supported beam type or izod test, and the test that is unfavorable for making a search has increased the instrument cost of testing laboratory.
Summary of the invention
The objective of the invention is provides a kind of improved Charpy impact machine tester at the deficiencies in the prior art, use the present invention both can effectively avoid departing from the phenomenon that barycenter causes the hammer stem bending because of striking point, simultaneously can also conveniently change impact energy and impact velocity, satisfy the requirement of a plurality of ranges.
The objective of the invention is to be achieved through the following technical solutions:
A kind of Charpy impact machine tester, form by frame, pendulum, jaw seat and pendulum hitch, pendulum is made of hammer body and hammer sword, the pendulum hitch is by balance staff and be sleeved on sway brace on the balance staff and the back-up block on the sway brace constitutes, the hammer body of described pendulum is a sector structure, which is provided with the counterweight hole of the assembled different quality counterweight of some, the small end of fan-shaped hammer body is the axis hole that cooperates with balance staff, and big end is inlayed the hammer sword.
As a kind of selection, the big end of described fan-shaped hammer body is inlayed free beam and is impacted sword, and the jaw seat is a free beam jaw seat.
Select as another kind, the big end of described fan-shaped hammer body is inlayed semi-girder and is impacted sword, and the jaw seat is a semi-girder jaw seat.
A kind of preferred pattern is, the big end of described fan-shaped hammer body is inlayed free beam simultaneously and is impacted sword and semi-girder impact sword, semi-girder impacts sword and is located at free beam impact sword below, the jaw seat comprises free beam jaw seat and semi-girder jaw seat, semi-girder jaw seat is located at the centre of free beam jaw seat, and is lower than free beam jaw seat sample support face.
Further, can change impact energy and impact velocity for making testing machine, described sway brace is rotatable certain angle on balance staff, makes the back-up block conversion height on it, thus change pendulum raise the angle in advance.
Beneficial effect of the present invention is, pendulum adopts the sector hammer body, it is long-pending to have reduced the longitudinal cross-section when increasing lateral stiffness, compare the Metallic rod pendulum, suffered windage is little, energy loss is little, and can avoid because of striking point departs from the phenomenon that barycenter causes the hammer stem bending, can assemble the different quality counterweight on pendulum, what can change pendulum raises the angle in advance, convenient impact energy and the impact velocity of changing, satisfy the requirement of a plurality of ranges, dismounting, debugging conveniently can realize dual-use, both make things convenient for manufacturing enterprise to use, helped the test that makes a search again.
