Technical Field
[0001] This utility model relates to the technical field of stamping dies, and in particular to a forming punch mechanism for engine parts. Background Technology
[0002] Engine parts are one of the important structures of automobiles. The efficiency and quality of the stamping mechanism in the current technology are not ideal. When the existing traditional stamping mechanism presses and shapes the product, it will interfere with the bending structure, thus failing to achieve accurate and efficient stamping processing. Therefore, it needs to be improved. Utility Model Content
[0003] To solve the above-mentioned technical problems, the present invention provides a shaping punch mechanism for engine parts, comprising: a punch for placing the engine part to be shaped, a swing block mounting seat connected to an upper die power source, and a swing block punch oscillating on the swing block mounting seat. The punch has a shaping cavity, the rear end of which extends upward to form a guide sidewall. The lower end of the swing block punch has a shaping recess for bending the engine part and a limiting guide part that cooperates with the guide sidewall. The top end of the swing block punch has a push rod, and an elastic member is provided between the push rod and the swing block mounting seat. The elastic member pushes the swing block punch to rotate so that it can smoothly contact the engine part and bend it into the shaping cavity. The limiting guide part cooperates with the guide sidewall to press the shaping recess tightly and fit the shaping surface of the engine part.
[0004] In a preferred embodiment of the present invention, the swing block punch is rotatably connected to the swing block mounting base via a rotating shaft and a cotter pin.
[0005] In a preferred embodiment of the present invention, the guide sidewall is an inclined surface that cooperates with the limiting guide portion.
[0006] In a preferred embodiment of the present invention, the elastic element is a nitrogen spring, and two sets of top rods are provided corresponding to the nitrogen springs.
[0007] In a preferred embodiment of the present invention, two sets of push rods are arranged side by side on the top surface of the swing block punch and located on the side of the rotating shaft close to the engine part to be shaped, for pushing the swing block punch to tilt so as to smoothly bend the engine part to be shaped into the shaping cavity.
[0008] In a preferred embodiment of the present invention, a flanged insert is installed inside the shaping cavity.
[0009] The beneficial effects of this utility model are: by using a nitrogen spring to push the swing block punch to rotate at a certain angle, the automotive parts to be stamped can be easily pressed into the forming cavity. Then, through the cooperation of the guide side wall and the limiting guide part, the forming recess on the swing block punch can be pressed tightly against the surface of the automotive parts, which can effectively improve the forming effect and efficiency, and improve the forming process.

[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 1-2 This utility model embodiment is a shaping punch mechanism for engine parts, including: a punch 1 for placing the engine part to be shaped, a swing block mounting seat 2 connected to the upper die power source, and a swing block punch 3 oscillating on the swing block mounting seat. The swing block punch is rotatably connected to the swing block mounting seat through a rotating shaft 4 and a cotter pin. A shaping cavity 5 is provided in the punch, and a flanged insert 6 is installed in the shaping cavity. The rear end of the shaping cavity extends upward to form a guide sidewall 7. The lower end of the swing block punch is provided with a shaping recess 8 for bending the engine part and a limiting guide part 9 that cooperates with the guide sidewall. During stamping, the limiting guide part cooperates with the guide sidewall to press the shaping recess tightly and fit the shaping surface of the engine part.
[0015] Furthermore, a push rod 10 is provided at the top of the swing block punch, and an elastic element 11 is provided between the push rod and the swing block mounting seat. The elastic element pushes the swing block punch to rotate so that it can smoothly contact the engine part and bend into the forming cavity. Specifically, the guide sidewall is an inclined surface that cooperates with the limiting guide part. The swing block mounting seat is driven downward by the upper die power source. Under the pushing action of the nitrogen spring, the swing block punch rotates at a certain angle, which can conveniently press the car part to be stamped into the forming cavity without generating stamping collision and conflict. During the process of the swing block punch entering the forming cavity, the inclined sidewall and the limiting guide part cooperate to make the forming concave part on the swing block punch press and press the surface of the car part, thereby improving the forming effect.
[0016] Specifically, the elastic component is a nitrogen spring. Two sets of push rods are provided corresponding to the nitrogen springs. The two sets of push rods are arranged side by side on the top surface of the swing block punch and are located on the side of the rotating shaft close to the engine part to be shaped. The nitrogen springs can push the swing block punch to tilt so as to smoothly bend the engine part to be shaped into the shaping cavity, which can help the swing block punch swing and reset.
[0017] In use, the engine part 12 to be shaped is placed on the shaping position of the punch. The upper die seat descends, driving the swing punch to move downward, which can easily press the car part to be stamped into the shaping cavity. The upper die continues to move downward, and the limiting guide part of the swing punch slides down along the guide side wall until the shaping recess presses and seals the surface of the car part, so as to complete the shaping process of the car part.
[0018] The beneficial effects of this utility model of a shaping punch mechanism for engine parts are: by using a nitrogen spring to push the swing block punch to rotate at a certain angle, the automotive parts to be stamped can be easily pressed into the shaping cavity. Then, through the cooperation of the guide side wall and the limiting guide part, the shaping recess on the swing block punch can be pressed tightly against the surface of the automotive parts, which can effectively improve the shaping effect and efficiency, and improve the shaping process.
[0019] 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.
