Technical field
The present invention relates to a kind of Charpy impact machine tester, and in particular to a kind of Chalpy impact pendulum.
Background technology
Charpy impact machine tester can be used for measure metal material to support shock proof performance under dynamic load state, so as to sentence
Mechanical property of the disconnected material under dynamic load effect, to obtain the impact absorbing energy of material and impact flexibility.At present, pendulum rushes
Hit testing machine and be divided into two kinds of impact tester for simple supported beam and radial-boom impact tester, the hammer body structure of its pendulum is similar, such as Fig. 7
It is shown, all it is that a c-type impact block is fixed in a metallic rod lower end, V-type impact sword, two kinds of examinations is inlayed in the C-shaped channel of impact block
It is different to test the jaw seat of machine, is respectively suitable for freely-supported beam type and beam type, raises angle angle in advance and be generally 120 °~150 °.It is existing
Deficiency existing for this radial-boom impact tester is mainly manifested in the following aspects：1st, using the pendulum of energy estimate methods, its
Function is single, and a machine can not do the impact test of multi-energy simultaneously, to realize energy conversion by changing whole pendulum,
Because of the weight weight of pendulum, during pendulum is changed, workload is big, and operation is heavy；2nd, existing pendulum mass uses c-type structure,
Pendulum locally uses oblique surface machining, and this structure can not minimize air drag；3rd, the structure of c-type pendulum hammer body makes hammer
The bad fixation of barycenter, to ensure barycenter on striking point, otherwise occurs that hammer stem is bent, it is necessary to counterweight repeatedly in impact test
Phenomenon.
The content of the invention
The present invention is in order to overcome drawbacks described above present in prior art, there is provided a kind of Chalpy impact pendulum.
The purpose of the present invention is achieved through the following technical solutions：
A kind of Chalpy impact pendulum, including pendulum mass hitch and pendulum mass, pendulum mass hitch include swing rod, are socketed in
Hook on the balance staff and swing rod of swing rod one end, the pendulum mass are U-shape structure, and the swing rod other end is provided with support base, described
Support base is connected with the center on the pendulum mass top, and the pendulum mass top and pendulum mass both ends, which are equipped with, can assemble matching somebody with somebody for weights
Repeated hole, the weights are fitted and connected with pendulum mass both ends, and the upper end of weights is provided with support block, the support block and pendulum
Body top connects with repeated hole.
In above-mentioned technical proposal, the pendulum mass uses U-shaped pendulum mass arc surface structure.The U-shaped pendulum mass arc surface structure is
The face in the face of the pendulum mass vertical with pendulum mass swaying direction, the i.e. pendulum mass vertical with pendulum mass both ends, using the design of arc surface.
In above-mentioned technical proposal, H set hammer swords are inlayed at the pendulum mass intermediate groove, and two symmetrical sides of H set hammer swords are adopted
It is more than both ends with the interior thickness of oblique surface machining, and every symmetrical side.
In above-mentioned technical proposal, plane is parallel with plane where the pendulum mass top where the H set hammers sword.
In above-mentioned technical proposal, swing rod indexable on balance staff, hook thereon is set to convert height, so as to change
Become the pre- of pendulum and raise angle.
In above-mentioned technical proposal, the pendulum raises angle as 105 °, 135 ° or 165 ° in advance.
The present invention is had the advantages that compared with prior art and advantage：
(1) pendulum uses the pendulum mass of U-shape structure, longitudinal cross-section product is reduced while lateral stiffness is increased, simultaneously
Pendulum mass integrally takes designed arc-shaped appearance, further minimizes windage, so as to which the energy loss of complete machine be minimized.
(2) the pendulum mass top connection swing rod of pendulum avoids in similar c-type pendulum the swing rod caused by striking point deviates barycenter
The phenomenon of bending.
(3) the pendulum mass both ends of pendulum can assemble different quality counterweight, and balance staff can change the pre- of pendulum and raise angle, and convenient change rushes
Energy and impact velocity are hit, meets that multipotency stroke uses, simple in construction, dismounting, debugging are convenient, simple operation.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail：
As depicted in figs. 1 and 2, the Chalpy impact pendulum that the present invention designs, including pendulum mass hitch and pendulum mass 4, pendulum
Body hitch includes swing rod 2, the hook 3 that is socketed on the balance staff 1 and swing rod of swing rod one end, the pendulum mass 4 be U-shape structure and
Using U-shaped pendulum mass arc surface structure 44；The other end of swing rod 2 is provided with support base 21, the support base 21 and the pendulum mass top
The center at end 41 is connected, the pendulum mass top 41 and pendulum mass both ends 42 be equipped with can assemble weights 5 match somebody with somebody repeated hole 43, it is described
Weights 5 are fitted and connected with pendulum mass both ends 42, and the upper end of weights 5 is provided with support block 51 (as shown in Figure 3 and Figure 4),
The support block 51 is connected with pendulum mass top 41 with repeated hole.
As shown in Figure 2, Figure 5 and Figure 6, H set hammers sword 45, and two symmetrical sides of H set hammer swords are inlayed at the intermediate groove of pendulum mass 4
451 use oblique surface machining, and the interior thickness on every symmetrical side 451 is more than both ends.The place plane of H set hammers sword 45 and the pendulum mass
The place plane of top 41 is parallel.
In the present invention, the balance staff of Chalpy impact pendulum is rotated, the rotatable certain angle of the swing rod on balance staff, is made thereon
Hook conversion height, raise angle so as to change the pre- of pendulum.Pendulum raises angle as 105 °, 135 ° or 165 ° in advance.These three angles
Position can produce three kinds of different test speeds respectively, be 3.7m/s at 105 °, be 4.3m/s at 135 °, be at 165 °
5.2m/s, while pendulum can be fixed with 105 ° -165 ° of other positions makes it produce required different impact speed in release
Degree.
The pendulum mass of the present invention is designed to U-shape structure, while designed arc-shaped appearance is integrally used on pendulum mass, further subtracts windage
To minimum, so as to which the energy loss of complete machine be minimized.
