Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1 and 2, a bending traceless profiling tool for bending a workpiece in cooperation with an upper die includes a base 10, an arc block 20, and a return member 30.
The top surface of the base 10 is provided with a V-shaped groove 11, and two sides near the V-shaped groove 11 are provided with arc-shaped grooves 12. The arc blocks 20 are provided with two groups and are correspondingly arranged in an arc groove 12. The upper surface of the arc block 20 is used for bearing a workpiece, and the arc block 20 can deflect along the radian direction of the arc groove 12. When the workpiece is bent, the upper die presses the workpiece downwards, the workpiece starts to be bent downwards, and meanwhile, one sides of the two groups of arc blocks 20, which are close to the V-shaped groove 11, move downwards along with the workpiece, so that the two groups of arc blocks 20 start to deflect along the radian direction of the arc groove 12. When the workpiece is bent to the bottom most point, the upper surfaces of the arcuate blocks 20 are aligned with both sides of the V-shaped groove 11.
The side of the arc block 20 far away from the V-shaped groove 11 protrudes radially to form a limiting table 21, and the limiting table 21 is matched with the top of the side wall of the arc groove 12 to limit the return position of the arc block 20.
The bending traceless profiling tool further comprises a return member 30, and the return member 30 is used for providing a force for returning the deflected arc-shaped blocks 20 to the original positions. Specifically, the return element 30 is a spring, one end of which is fixed on the side of the arc block 20 away from the V-shaped groove 11, and the other end of which is fixed on the base 10. The return member 30 includes 4 sets of springs, and two sets of springs are correspondingly disposed on each of the arc blocks 20.
The base 10 is provided with a receiving groove 13 for receiving the return member 30, and the receiving groove 13 is provided on one side of the arc-shaped groove 12 away from the V-shaped groove 11.
In the above scheme, the arc-shaped groove 12 is a semicircular groove, and the arc-shaped block 20 is a semicircular block. The arc-shaped grooves 12 on both sides of the V-shaped groove 11 are mirror images of each other, and the arc-shaped blocks 20 on both sides of the V-shaped groove 11 are mirror images of each other.
The utility model discloses a no trace profile modeling frock of bending, when bending, go up the mould and push down the work piece, the work piece begins to be bent downwards, and 11 one side of being close to the V-arrangement groove of two sets of arc pieces 20 are followed simultaneously and are moved down for two sets of arc pieces 20 begin to deflect along the radian direction of arc 12. When the workpiece is bent to the bottom most point, the upper surfaces of the arcuate blocks 20 are aligned with both sides of the V-shaped groove 11. The pressure of the upper die is mainly born by the two groups of arc-shaped blocks 20 in the process, and the arc-shaped blocks 20 deflect along with the bending of the workpiece, so that the contact surface of the arc-shaped blocks 20 and the workpiece cannot slide, and friction marks cannot appear.
