[0003] This invention addresses the shortcomings of existing technologies by providing a double-sided forming mechanism with an adjustable bending angle. It utilizes notches on the left and right punches to accommodate and avoid the raised fins of the part to be formed. Adjusting bolts adjust the distance between the pad and the drive block, causing the drive block to push the left or right punch to slide, thereby adjusting the bending angle between the forming part and the part, resulting in higher adaptability. Furthermore, by using the forming part to press against the forming surfaces on both sides of the part, the forming effect and efficiency can be effectively improved.

A left punch and a right punch are slidably disposed on the left slider seat and the right slider seat, respectively. The left oblique wedge and the right oblique wedge have a cavity. A wedge-shaped adjusting block is slidably disposed inside the cavity. A driving block is disposed on the wedge-shaped adjusting block. The driving block has a ramp surface that contacts the left punch or the right punch. A guide plate is disposed on the ramp surface. A shaping part is disposed on the end face of the left punch and the right punch that contacts the part to be shaped. During stamping, the shaping part is pressed tightly against both sides of the part to be shaped and fits against the shaping surface of the part to be shaped. The pad is connected to the wedge-shaped adjusting block through the left or right inclined wedge seat by an adjusting bolt.
[0005] In a preferred embodiment of the present invention, the left punch and the right punch are provided with notches for accommodating the raised wing portion of the part to be shaped.
[0006] In a preferred embodiment of the present invention, the notch is an inverted "V" shaped structure.
[0007] In a preferred embodiment of the present invention, the end face of the shaping part that contacts the part to be shaped is an arc surface.
[0008] In a preferred embodiment of the present invention, the wedge-shaped adjusting block and the driving block are connected as a linked whole, and the distance between the pad and the driving block is adjustable.
[0009] In a preferred embodiment of the present invention, a limiting washer is provided on the upper end surface of the left slider seat or the right slider seat.
[0010] The beneficial effects of this utility model are as follows: the notches on the left and right punches accommodate and avoid the raised wings of the part to be shaped, so that there is no interference with the bending structure during stamping; the distance between the pad and the drive block is adjusted by adjusting the bolts, so that the drive block pushes the left or right punch to slide, thereby adjusting the bending angle of the forming part in contact with the part, resulting in a higher degree of adaptability; the forming part presses against the forming surfaces on both sides of the part, which can effectively improve the forming effect and efficiency.

Detailed Implementation
[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0013] Please see Figure 1-3This utility model embodiment is a double-sided forming mechanism with adjustable bending angle, including: a punch 1 for placing the part to be formed, a left oblique wedge 2 and a right oblique wedge 3 symmetrically arranged on both sides of the punch, a pad 4 arranged on the outside of the left oblique wedge and the right oblique wedge, and a left slider seat 5 and a right slider seat 6 connected to the upper die power source. The left slider seat and the right slider seat are arranged side by side on the same plane. A left punch 7 and a right punch 8 are slidably arranged on the left slider seat and the right slider seat, respectively. The top of the left punch and the right punch has a snap-fit connector. The slider seat is provided with a snap-fit groove that cooperates with the snap-fit connector. The snap-fit connector has an "I" shaped structure. During installation, the snap-fit connectors of the left punch and the right punch are slowly slid inward along the snap-fit groove.
[0014] Specifically, the left and right oblique wedges each have a cavity, within which a wedge-shaped adjusting block 9 is slidably disposed. A driving block 10 is mounted on the wedge-shaped adjusting block, and the wedge-shaped adjusting block and the driving block are connected as a single linked unit. A pad is connected to the wedge-shaped adjusting block via an adjusting bolt passing through the left or right oblique wedge, thereby adjusting the distance between the pad and the driving block. When stamping parts of different specifications according to production needs, the distance between the pad and the driving block is adjusted by selecting adjusting bolts of different lengths or adjusting the depth of screwing in the adjusting bolts. The bending angle between the forming part and the workpiece has a higher adaptability. The drive block has a ramp surface that contacts the left or right punch. A guide plate 11 is provided on the ramp surface. The guide plate contacts the left and right punches and plays a guiding role during the pressing process of the left and right punches, so that the two sets of punches gradually move closer together to perform bending operations on both sides of the workpiece to be formed. The end faces of the left and right punches that contact the workpiece to be formed are provided with forming parts 12. During stamping, the forming parts press tightly against both sides of the workpiece to be formed and fit against the forming surface of the workpiece to be formed, thereby improving the forming efficiency.
[0015] Specifically, the left and right punches are provided with notches 13 for accommodating the raised wings of the part to be shaped. The notches are inverted "V" shaped structures. The notches on the left and right punches are used to accommodate and avoid the raised wings of the part to be shaped, so that there will be no interference with the bending structure during stamping.
[0016] Specifically, the end face of the shaping part that contacts the part to be shaped is an arc surface, which facilitates better fit with the surface of the part during shaping and improves the yield of shaping.
[0017] Specifically, a limiting washer 14 is installed on the upper surface of the left or right slider seat by fasteners to limit the backward movement of the drive block.
[0018] During stamping, the part to be formed 15 is placed in the forming position on the punch. The upper die seat descends, driving the left and right punches to move downwards, which can easily press the part to be stamped into the left or right inclined wedge. The upper die continues to move downwards, and the left and right punches slide downwards along the downward slope guide surface of the drive block, so that the forming part presses the surface of the part to complete the forming process of the part.
[0019] The beneficial effects of this utility model's adjustable bending angle double-sided forming mechanism are as follows: the notches on the left and right punches accommodate and avoid the raised fins of the part to be formed, preventing interference with the bending structure during stamping; adjusting the distance between the pad and the drive block using the adjusting bolt allows the drive block to push the left or right punch to slide, thereby adjusting the bending angle between the forming part and the part, resulting in higher adaptability; and the forming part pressing against the forming surfaces on both sides of the part effectively improves the forming effect and efficiency.
[0020] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
