Description

Technical Field

[0001] The utility model relates to the technical field of continuous molds, in particular to a continuous stamping mold for a bracket. Background Art

[0002] Among automotive parts, the "X"-shaped bracket is particularly widely used. To improve efficiency, existing molds mostly form the C and D parts of the bracket in one step through the mold. However, this method is generally only suitable for materials with lower strength. With the widespread use of high-strength materials, the shape of the bracket is partially restored after the forming load is removed. The shape and size of the bracket do not match the shape and size of the working surface of the stamping die, causing the size of the bracket to be out of tolerance, affecting the assembly accuracy of the bracket.

A first punching assembly 4, a second punching assembly 5, a co-cut assembly 6, a first forming assembly 7, a second forming assembly 8, and a trimming assembly 9 are sequentially arranged between the upper die base 1 and the lower die base 2 along the product conveying direction. The first forming assembly 7 includes a first upper forming block 701 installed on the upper die base 1, a first lower forming block 702 installed on the lower die base 2 and cooperating with the first upper forming block 701, and the first lower forming block 702 The bottom of the mold is provided with a tension spring 705, and sliders 703 are slidably provided on both sides of the first lower forming block 702. The two ends of the slider 703 are inclined surfaces. An inclined wedge 704 is installed on the upper mold base 1 to cooperate with the inclined surface of one end of the slider 703. The inclined surface of the other end of the slider 703 slides with the first lower forming block 702. Specifically, the material strip is fed to the position of the first punching assembly 4 through the automatic feeder, and the bracket A is punched by the first punching assembly 4. Then the automatic feeder moves the material strip forward by the position of a bracket, and the bracket is punched by the second punching assembly 5. Punching is performed at B. After punching, the material strip is moved forward to the position of a bracket, and the required outline and size of the bracket are punched out by the co-cutting component 6. A certain margin will be left when the co-cutting component 6 is punched, so that the punched bracket can continue to be sent to the first lower forming block 702. Then the upper die base 1 drives the first upper forming block 701 and the inclined wedge 704 to move downward. The inclined wedge 704 cooperates with the inclined surface at one end of the slider 703 to push the slider 703 to move to the middle. The inclined surface at the other end of the slider 703 slides with the bottom of the first lower forming block 702 to make the first The lower forming block 702 moves upward and cooperates with the first upper forming block 701 to bend the bracket at C. After the bending of the bracket at C is completed, the first upper forming block 701 and the wedge 704 move upward, and the first lower forming block 702 moves back to its original position under the action of the tension spring 705, ready for the next forming. Then the material strip moves forward again and sends the bracket to the second forming component 8. The second forming component 8 bends the bracket at D. Then the bracket moves to the cutting component 9, and the cutting component 9 cuts the formed bracket from the material strip.
