Embodiment example 1

[0036] Implementation case 1, finishing cylindrical ice specimen:

[0037] Hold the ice specimen to be processed:

[0038] The operator grabs the ice specimen to be processed with the left hand, pulls the locking hinge head 18 with the right hand, and then passes the ice specimen to be processed through the center of the locking hinge 9, puts it into the fixture for clamping, and tightens the locking screw at the right end for axial restraint .

[0039] To cut one end of an ice specimen:

[0040] Constantly adjust the left and right positions of the cutter set 11 so that the radial blade 5 is close to the left end of the ice test piece 7 . The position of the circumferential blade 4 is continuously adjusted so that the circumferential blade 4 is close to the outer wall of the ice test piece 7 . Lift and press the cutting handle downward and reciprocatingly. At this time, the radial blade 5 will cut the left end of the ice test piece 7 to reduce the length of the ice test pi...

Embodiment example 2

[0045] Example 2: A disc-shaped ice specimen was obtained by finishing.

[0046]First, complete the step of "holding the ice specimen to be processed" in the above "implementation case 1".

[0047] Truncated ice specimen:

[0048] The cutter set 11 is adjusted so that both the circumferential blade 4 and the radial blade 5 on the cutting handle 2 are slightly away from the ice test piece 7 . Adjust the left and right positions of the truncation handle. Press down the cutting handle 3 and place the cutting handle on the side close to the operator. Hold the cutting handle 2 in the left hand and the cutting handle 3 in the right hand. The left and right hands swing up and down together, and the swing range will be larger than the cutting range.

[0049] When the aforementioned two handles move downward, the cutting blade 8 will cut the ice test piece 7 and cut a dent on the ice test piece 7; Lift, do not cut. At the same time, the ice specimen 7 is controlled by the synchro...

Abstract

A finishing device for a cylindrical ice test piece of the present invention comprises a base, a tool set, a synchronous rod, a radial synchronous bar, a locking hinge and a clamp; the clamp is connected to the base through a thrust bearing, and the tool set includes Cutting handle, the radial blade arranged on the cutting handle, the cut-off handle, the circumferential blade and the cut-off blade arranged on the cut-off handle; The bearing is connected with the ratchet; the left end of the base is also provided with a locking screw and an axial spring; the cutting handle, the truncation handle, and the clamp can rotate freely around the same horizontal axis. The invention can provide processors and testers with a high-quality cylindrical and disc-shaped ice test piece that is convenient to manufacture with uniform specifications, high dimensional accuracy, and no micro-cracks inside due to vibration, and has the ability to cut off rod-shaped ice test pieces. The position of the section is controllable, and the section is smooth without burrs.

Description

technical field [0001] The invention relates to a finishing device, in particular to a finishing device for a cylindrical ice test piece. Background technique [0002] When performing uniaxial compression of ice specimens, it is necessary to obtain cylindrical ice specimens of specified dimensions. Before the microstructure observation experiment of the ice sample is carried out, it is necessary to obtain a disk-shaped ice sample with a certain thickness. However, it is difficult to obtain ice specimens with accurate dimensions in actual processing operations, and the mechanical vibration during processing is likely to cause micro-cracks inside the ice specimens. Therefore, a finishing device for cylindrical ice specimens is required to solve the above problems. [0003] The patent number is CN201710851824.3, and the invention patent titled "A Device for Making Ice Test Pieces" discloses a device for making ice test pieces, but the electric saw can only perform straight li...
