The holding mold 400 is provided with a dumbbell-shaped molding cavity 410 for holding the sample strips, and in the embodiment, the holding mold 400 can be selected from the existing holding structure, such as a sample making mold involved in a sample making machine for plastic pipe stretching experiments of CN 202021864966.7. A strip of plastic tubing spline is clamped in the molding cavity 410. Under the combined action of the moving mechanism 300 and the elastic buffer mechanism 500, the side faces of the splines are attached to the blades 210 of the cutting knife tackle 200, the holding die 400 moves, and the blades 210 cut the splines into dumbbell shapes along the molding cavities 410.
The moving mechanism 300 includes a first moving base 310 and a driving mechanism 320, and the first moving base 310 may be slidably mounted on the machine table 100 through the guide rail 110. In this embodiment, the guide rail 110 is disposed in a left-right direction, the first movable base 310 is driven by the driving mechanism 320 to move laterally along the guide rail 110, and the driving mechanism 320 may be driven by a motor. The cutter unit 200 is located at the front side of the first movable base 310. The clamping mold 400 is installed on the first sliding seat, and the left side of the clamping module is hinged to the first movable seat 310. in this embodiment, a rotating head 311 is installed on the first movable seat 310, the rotating structure can be rotatably installed on the first movable seat 310 through a bearing assembly, and the rotating axis of the rotating head 311 is vertically upward in space. A clamping seat 312 is disposed on the rotating head 311, and the clamping seat 312 may be plate-shaped and extends upward from the rotating head 311. The clamping seat 312 rotates on the first movable seat 310 along with the rotating head 311 around the central axis of the rotating head 311. The left side of the clamping mold 400 is provided with a mounting groove 420, the mounting groove 420 is matched with the clamping seat 312, the clamping seat 312 is inserted into the mounting groove 420, and the clamping mold 400 can rotate on the first movable seat 310 along the horizontal direction around the central axis of the rotating head 311 through the clamping seat 312.
The elastic buffer mechanism 500 is installed on the machine platform 100, and the elastic buffer mechanism 500 is connected with the clamping mold 400. The holding mold 400 and the elastic buffer mechanism 500 move laterally with the first movable base 310. When the cutting knife set 200 cuts the bead clamped on the clamping die 400, the position of the cutting knife set 200 on the machine table 100 is fixed, the clamping die 400 swings back and forth around the rotating head 311 on the first moving seat 310 relative to the cutting knife set 200 along the forming cavity 410, and meanwhile, the elastic buffer mechanism 500 has an elastic acting force pushing towards the direction of the cutting knife set 200 on the clamping die 400, namely, when the first moving seat 310 moves transversely and the clamping die 400 rotates, the front side of the forming cavity 410 of the clamping die 400 is attached to the rolling surface of the cutting edge 210 under the action of the elastic buffer mechanism 500, and the spline is ensured to be cut into a dumbbell shape along with the forming cavity 410.
In some embodiments of the present invention, the elastic buffer mechanism 500 includes a second movable base 510, a fixed base 520, a buffer base 530 and an elastic member 540. The second movable base 510 may be slidably mounted on the machine table 100 through the slide rail 120. The fixed base 520 is fixed on the second movable base 510, the buffer base 530 is located in front of the fixed base, the buffer base 530 and the fixed base 520 are connected by a plurality of elastic members 540, and the front side of the buffer base 530 faces a direction of pushing the clamping mold 400 toward the cutting blade assembly 200. Before cutting, the second movable base 510 moves the buffer base 530 to the rear side of the clamping mold 400, the buffer base 530 abuts against the rear side of the clamping mold 400, and the fixed base 520 moves forward, so that the elastic members 540 are compressed and elastically deformed between the buffer base 530 and the fixed base 520. During the cutting process, the buffer seat 530 automatically moves back and forth in an adaptive manner along with the movement of the clamping mold 400, and the buffer seat 530 keeps pushing the clamping mold 400 towards the cutting knife block 200 by using the action of the elastic element 540, so that the cutting knife block 200 cuts the splines into dumbbell shapes along the forming cavity 410. In addition, after the cutting is completed, the second moving block 510 may be moved to separate the buffer block 530 from the clamp mold 400, and then the clamp mold 400 may be rotated in a rear direction about the rotating head 311 away from the cutting blade group 200, thereby taking out the splines on the clamp mold 400.
Further, since the clamp die 400 moves laterally left and right along with the first movable base 310 during the cutting process, friction may occur between the clamp die 400 and the buffer base 530, in order to reduce the sliding friction, a plurality of pulleys 531 are disposed on an end surface of the buffer base 530 facing the clamp die 400, and when the clamp die 400 moves laterally, the pulleys 531 roll on the clamp die 400.
In some embodiments of the present invention, the second movable base 510 is moved before cutting, and after the second movable base 510 is positioned, the second movable base 510 is fixed on the current position of the machine table 100 by using the locking member 550, and the locking member 550 may be a screw. The locking member 550 is screwed with the machine table 100 by passing downward through the second movable base 510. Correspondingly, a threaded hole is preset on the machine table 100.
In order to facilitate the second movable base 510 to drive the buffer base 530 to exit, the slide rail 120 on the machine table 100 is disposed in a front-left direction, i.e., the slide rail 120 is parallel to the moving direction of the first movable base 310, and the moving direction of the second movable base 510 is parallel to the moving direction of the first movable base 310. When it is necessary to rotate the clamping mold 400 backward after the cutting is completed, the second movable base 510 can be rapidly withdrawn.
