Abstract

The utility model provides a test sample hanger device, which comprises a test sample support (1), a hanger (2), a spring (3) and a hinge rotary shaft (4). The hanger device is made into a cross shape; the rotary shaft (4) of a hinge structure of the hanger and the support (1) are manufactured into a whole; and the test sample support (1) and the hanger (2) are mechanically connected by the spring. The test sample hanger device enhances shock resistance of the test sample hanger, and prolongs the service life of the hanger. Besides, the hanger device achieves buffering and vibration absorbing purposes, reduces large impact from a hammer to the lowest, increases experiment accuracy and experiment safety coefficient, and buffers hard impacting load.

Description

A kind of sample hooking device

Technical field

The utility model relates to a kind of sample hooking device, is specially adapted to be equipped with the sample hooking device that dropping hammer of flip type sample presentation system torn the impact testing machine sample presentation system.

Background technology

During current hot-rolled coil was produced, the terminal check of roll bending was improving the steel product quality, is enlarging kind, is reducing cost, optimizes aspect such as steel rolling production technology and bringing into play important effect, even has become the restricted link in the whole process of production.Drop hammer and tear the important way that impact experiment is product made from steel check, it especially has high reference value aspect the pipe line steel examination and test of products, is the important evidence that high-end variety steel such as pipe line steel is produced.

Adopt ZCJ-40000J to drop hammer to tear impact testing machine when the pipe line steel sample is carried out the drop impact experiment, at first make the sample presentation frame go out frame, the sample that will drop hammer is put in the sample presentation frame, then, and sample presentation frame sample presentation, the sample hook supports sample during sample presentation, after the sample presentation frame was in place, the sample hook sank in the sample pocket for the punch head, at this moment, sample is placed on the bearing that drops hammer, and the sample hook breaks away from sample.When dropping hammer, the hammer body of 750kg freely falls from the eminence of 2m sample is thrust.Sample presentation frame and sample hook quick rebound under the huge rigid shock load of hammer body, and the residual sample that drops hammer that causes sample to link up with and thrust sharply collides and is out of shape.When sample hook slight deformation, support the sample presentation frame and separate with support body, cause the inductor induction less than sample, can only start the pressure recognition button, force to finish experiment; When the sample deformation of hook was serious, the sample hook can not sink in the sample pocket for the punch head fully, causes sample can not lie on the bearing that drops hammer, can't satisfy basic experimental conditions, cause scrapping of sample hook, make the life-span of sample hook extremely short, even all need to change the sample hook every day.

Therefore how to avoid or what alleviate the problems referred to above is the key point that experiment normally carries out of dropping hammer.Head it off needs the practical working situation in conjunction with the sample hook, studies, improves and improve from the suffered rigid impact of buffering sample hook, the physical construction of improving the sample hook, the many-sides such as work efficiency that improve the experiment of dropping hammer.

Summary of the invention

The purpose of this utility model provides a kind of sample hooking device, can strengthen the shock resistance of sample hook, improves the sample hook life-span; Reach the purpose of buffering absorbing in addition, it is minimum that enormous impact from hammer body is dropped to, and improves experimental precision, experiment safety coefficient and cushion rigid shock load.

The technical solution of the utility model is: a kind of sample hooking device, it is characterized in that: by sample mount, hook, spring, and the hinge rotating shaft form, make the right-angled intersection shape, the rotating shaft of the hinge arrangement of hook is integral with rack making, adopts spring to carry out mechanical connection between sample mount and the hook and forms.

The beneficial effects of the utility model: a kind of sample hooking device is interted with hook by sample mount is in the same place, and link together by the end of spring with sample mount and hook, be combined into the right-angled intersection shape, in order to strengthen the shock resistance of sample hook, the hinge rotating shaft of hook is integral with rack making, thereby strengthened the shock resistance of the hinge rotating shaft of sample hook, made the life-span of sample hook prolong 10 times; In addition, adopted the spring connection between support of the present utility model and the hook, thereby reached the purpose of buffering absorbing, it is minimum that enormous impact from hammer body is dropped to, and improves experimental precision, experiment safety coefficient and cushion rigid shock load.

Description of drawings

Fig. 1 is a kind of sample hooking device of the utility model structural representation;

Fig. 2 is the structural scheme of mechanism of the utility model sample hook support and hinge rotating shaft.

Wherein, 1. support, 2. hook, 3. spring, 4. hinge rotating shaft.

Embodiment

Be described in further details below in conjunction with the embodiment of accompanying drawing a kind of sample hooking device of the utility model:

As shown in Figure 1, the utility model is a kind of drop hammer safety-type, the shock absorbing load type of tearing impact experiment, sample hook that turns type of being applicable to, its objective is in order to improve experimental precision, experiment safety coefficient and to cushion rigid shock load and use.The utility model is interted with sample hook 2 by sample hook support 1 is in the same place, and is linked together by the end of spring 3 with sample hook support 1 and sample hook 2, is combined into the right-angled intersection shape.In order to strengthen the shock resistance of sample hook, the hinge rotating shaft 4 that sample is linked up with is made into one (as shown in Figure 2) with the sample hook support, thereby has strengthened the shock resistance of the hinge rotating shaft of sample hook, makes the life-span of sample hook prolong 10 times.Adopted the spring connection between sample hook support of the present utility model and the sample hook, thereby reached buffering absorbing purpose, made enormous impact drop to minimum from hammer body.

The utility model provides a kind of sample hooking device, is the rotation sample hooking device of a kind of high safety performance, available buffer absorbing, has improved experimental precision, experiment safety coefficient and has cushioned rigid shock load.

Claims

1. sample hooking device, it is characterized in that: by sample mount (1), the hook (2), spring (3), and hinge rotating shaft (4) form, make the right-angled intersection shape, the same support of rotating shaft (4) (1) of the hinge arrangement of hook is made into one, adopts spring to carry out mechanical connection between sample mount (1) and the hook (2) and forms.
