Detailed Description

The present invention will be more clearly and completely described with reference to the following preferred embodiments and the accompanying drawings.

As shown in fig. 1 and 2, the plasticity detection apparatus for a tungsten alloy thin material in the present embodiment includes a work table 1, and a clamping mechanism for clamping a workpiece to be detected and a bending mechanism for bending the workpiece to be detected are provided on the work table 1.

Specifically, the clamping mechanism includes a static pressure pad 8 fixed to the table plate 1, and a dynamic pressure pad 7 movable relative to the static pressure pad 8. The dynamic compression block 7 has a detection angle (see fig. 2) near the edge of the bending mechanism, and different detection angles can be changed for detection by changing different dynamic compression blocks. The dynamic pressure pad 7 is connected to the cylinder 4 as a first driving member. Wherein, the extending direction of the cylinder 4 and the moving direction of the dynamic compression block 7 form a certain included angle, and the structure of the whole device can be more compact through the design of the included angle. An elbow clamping seat 5 is arranged on the working table plate 1, an elbow clamp 6 is arranged on the elbow clamping seat 5, and a piston of the air cylinder 4 is connected with a dynamic pressing block 7 through the elbow clamp 6.

In order to ensure that the motion between the dynamic compaction block and the static compaction block is always kept in a linear state, a guide post 9 is further arranged on the dynamic compaction block 7 and points to the static compaction block side 8, and a guide hole penetrating through the guide post 9 is formed in the static compaction block 8.

The bending mechanism comprises a rotatable bending turntable 2 arranged on the working table plate 1, and a bending pressure plate 3 is arranged on the bending turntable 2. The curved platen 3 includes a first contact surface that contacts the workpiece 100 to be inspected; the static pressure pad 8 includes a second contact surface for contacting the workpiece 100 to be inspected.

In the initial state, the first contact surface is flush with the second contact front surface (see fig. 1), and the center of rotation of the curved carousel 2 coincides with the line of intersection of the first contact surface and the second contact surface. That is, when the curved turntable 2 rotates, the curved platen 3 rotates around the intersection line. The bending turntable 3 is connected with a speed regulating motor 10 as a second driving member.

In addition, an arc scale is arranged on the edge of the working table plate 1 close to the bending turntable 2, so that the size of the rotation angle can be known at the first time in the detection process. In order to avoid excessive rotation of the bending turntable 2 after the workpiece to be detected is bent to a preset bending angle, the plasticity detection device for the tungsten alloy thin material further comprises a position sensor, and the position sensor is connected with the air cylinder and the speed regulating motor.

The working process is that a dynamic pressing block with a proper testing angle is selected for installation, and a tungsten alloy sheet to be detected is manually placed between the dynamic pressing block and the static pressing block. The power supply and the pneumatic switch 11 are started, the speed of the speed regulating motor 10 is regulated to a proper gear, the position sensor is placed at the position of the bending turntable 2 required to stop at a corresponding angle, then the rotating speed switch is started, and the bending pressure plate 3 can push the tungsten alloy sheet (namely the workpiece 100 to be detected) to bend. The bending action will automatically stop until the position sensor is rotated, and will reverse back to the starting position. The plasticity detection device for the tungsten alloy thin material can rapidly and quantitatively judge the bendable R angle and the corresponding bendable angle of the tungsten alloy, so that the plasticity of the tungsten alloy thin sheet is judged.
