Detailed Implementation

[0013] 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.

[0014] Please see Figure 1-3This utility model embodiment is a forming mechanism with an adjustable angle that can be used with the punch. It includes: an upper left punch 1 and an upper right punch 2 connected to the upper die power source; a punch 3 for placing the part to be formed; a left wedge seat 4 and a right wedge seat 5 symmetrically arranged on both sides of the punch; and a side guide plate 6 arranged on the outside of the left and right wedge seats. The left and right wedge seats are slidably arranged on the lower die. Specifically, the lower die is provided with a slide rail, and the left and right wedge seats are connected to the sliders on the slide rail.

[0015] The left and right wedge-shaped seats each have an arc-shaped cavity 7. A cam adjusting block 8 is slidably disposed within the cavity. The cam adjusting block has a shaping inclined surface 81 that contacts and engages with the upper left punch or upper right punch. The back side of the shaping inclined surface is an adjusting part 82 that rolls in conjunction with the cavity. The adjusting part extends toward the cavity to form a protrusion (not shown in the figure). The two ends of the protrusion are recessed inward to form a limiting arc surface 83. The left wedge-shaped seat or right wedge... The seat is provided with a receiving groove 9 to accommodate the protrusion. Limiting washers 10 are respectively provided at both ends of the protrusion in the receiving groove. The limiting washers are fixed to the left wedge seat or the right wedge seat by bolts and slide in contact with the limiting arc surface. When stamping parts 12 of different specifications according to production needs, the product to be shaped comes into contact with the shaping inclined surface. By using the cam adjusting block to slide in the cavity, the bending angle of the shaping inclined surface in contact with the part can be adjusted, resulting in a higher degree of adaptability.

[0016] Specifically, the punch and the right punch are provided with a ramp surface 11 that matches the forming ramp surface. The upper left punch and the upper right punch play a guiding role during the pressing process, so that the two sets of punches gradually move closer together to perform bending operations on both sides of the part to be formed. During the stamping, the ramp surface and the forming ramp surface press tightly against both sides of the part to be formed and fit against the forming surface of the part to be formed, thereby improving the forming efficiency.

[0017] Specifically, the end face of the adjustment part that contacts the cavity is an arc surface, which makes it easier to roll within the cavity to adjust the tilt position when in contact with the part. This facilitates better contact between the shaping slope and the surface of the part during shaping, thus improving the yield rate of shaping.

[0018] Specifically, the protrusion extends along the length of the cam adjusting block, and both ends are recessed inward to form a limiting arc surface. The protrusion and the adjusting part are integrally formed. The receiving groove is installed through the left wedge seat or the right wedge seat and is connected to the cavity. Two sets of limiting washers are pressed and positioned in the receiving groove of the left wedge seat or the right wedge seat by bolts, so as to roll and position the entire cam adjusting block in the cavity. The protrusion can rotate freely in the receiving groove to facilitate the adjustment of the fitting angle between the forming slope and the part, so as to complete the forming process of the part and achieve a higher degree of fit.

[0019] The beneficial effects of this utility model of a forming mechanism with freely adjustable angles in conjunction with punches are: by using a cam adjusting block to slide within the cavity to adjust the bending angle of the forming inclined surface on it in contact with the part, the adaptability is higher; by using the inclined surfaces on the upper left punch and upper right punch to cooperate with the forming inclined surface to press and adhere to both sides of the part for part forming, the forming effect and efficiency can be effectively improved.

[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.
