Description

Technical Field

[0001] The utility model relates to the technical field of metal parts, and particularly discloses an elasticity detection device for metal parts. Background Art

[0002] After metal parts are processed, they need to be tested. At present, hardness testing devices generally use an extrusion mechanism to directly pressurize the metal parts. However, when using the extrusion mechanism, it is impossible to quickly reset when the pressure on the metal parts reaches the set value. As a result, as the pressure increases, the metal parts will directly break, so that metal fragments will fly, which can easily cause safety accidents.

[0004] The above document discloses an elasticity detection device for metal parts, which has the following problems: when the electromagnetic ring is powered off, the carrier plate falls directly downward, causing the carrier plate to collide with the base plate with great kinetic energy. The metal parts inside the carrier plate are easily ejected from the carrier plate, and the collision between the carrier plate and the base plate is likely to damage the carrier plate and the base plate, which requires improvement.

The front and rear ends of the outer wall of the screw rod are threadedly connected to sliders, and the upper end surfaces of the two sliders are fixedly connected to splints.

[0008] In order to facilitate the relative or opposite movement of the two clamping plates when the screw is rotated, as a preferred elasticity detection device for metal parts of the present invention, the thread directions of the front and rear ends of the screw are opposite.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] This elasticity detection device for metal parts can connect or disconnect the first connecting plate and the second connecting plate by energizing or de-energizing the electromagnet. When the power is cut off when the pressure value on the metal part reaches the set value, the magnetic force of the electromagnet disappears, causing the first connecting plate to be disconnected from the second connecting plate, so that the downward pressure of the hydraulic cylinder can no longer act on the pressure plate, preventing the pressure from continuing to increase and causing the metal part to be directly broken. The metal part is fixed to the support table by two clamping plates, solving the problem of metal parts being easily popped out in the past. BRIEF DESCRIPTION OF THE DRAWINGS
