Description

Technical Field

[0001] The invention relates to a boss forming device of a metal material and a forming process thereof. Background Art

[0002] For some products with bosses on metal surfaces, such as heat dissipation copper sheets, thicker metal plates are currently usually machined during production. This processing method wastes a large amount of metal materials, resulting in high costs, and the processing procedures are cumbersome and inefficient. Summary of the Invention

[0003] In response to the above problems, the present invention provides a boss forming device for metal materials and a forming process thereof, which effectively solves the problems pointed out in the background technology.

[0004] The technical solution adopted in the present invention is:

[0005] A boss forming device for metal materials includes a lower mold positioning plate and an upper mold fixing plate. An elastic clamping mechanism is fixed to the bottom of the upper mold fixing plate. A side slider is provided at the bottom of the elastic clamping mechanism and is connected to the elastic clamping mechanism for left and right sliding movement. A boss cavity is provided at the bottom of the side slider. A shovel pin is vertically fixed to the side of the boss cavity of the side slider. A slope is provided at one end of the side slider. An inclined wedge matching the slope is fixed to the bottom of the upper mold fixing plate.

[0006] The method of inserting the spade needle into the metal plate can process thicker metal plates.

[0007] Preferably, a slide rail matching the side slider is provided at the bottom of the elastic pressing mechanism.

[0008] The side sliding block slides left and right on the bottom of the elastic pressing mechanism through the sliding rail, thereby facilitating the sliding of the side sliding block.

[0009] Preferably, the elastic pressing mechanism is a nitrogen spring.

[0010] Nitrogen springs have large elastic force, long stroke, stable operation, precision manufacturing, long service life, and a gentle elastic curve, making them suitable for stamping.

[0011] Preferably, the bottom end of the shovel needle protrudes from the bottom of the side slider.

[0012] Preferably, the length of the shovel pin extending out of the bottom of the side slider is equal to the depth of the boss cavity, and the width of the shovel pin matches the width of the boss cavity.

[0013] Depending on the different boss cavities, the size and length of the shovel pin need to be changed accordingly. In actual work, it is necessary to ensure that the length of the shovel pin extending from the bottom of the slider is equal to the depth of the boss cavity, and the width of the shovel pin is equal to the width of the boss cavity, so that a high-quality boss can be formed.

[0014] Preferably, the lower die positioning plate is provided with an outer shape positioning mechanism or a hole positioning mechanism.

[0015] The shape positioning mechanism or hole positioning mechanism is used for positioning the metal plate.

[0016] The working principle of this device includes the following steps:

[0017] 1. Place the metal plate on the lower die positioning plate and fix it;

[0018] 2. Control the upper die fixing plate to press down so that the shovel pins on the side slider are inserted into the metal plate. At this time, the elastic pressing mechanism contracts.

[0019] 3. Control the upper die fixed plate to continue pressing down, the inclined wedge drives the side slider to slide horizontally, and the shovel needle scoops up part of the material on the surface of the metal plate and pushes it into the boss cavity until the boss cavity is completely filled, completing the boss forming;

[0020] 4. Control the upper mold fixing plate to loosen and remove the metal plate to obtain the metal plate with completed boss forming.

[0021] In step 3, the sliding distance of the side slider during horizontal sliding is adjusted by controlling the downward pressing distance after the inclined wedge and the side slider collide with each other.

[0022] The present invention also provides a boss forming process of a metal material, comprising the following steps:

[0023] 1) Place the metal plate on the lower die positioning plate and fix it;

[0024] 2) Control the upper die fixing plate to press down so that the shovel needle is inserted into the metal plate;

[0025] 3) Control the shovel needle to scoop up part of the material on the surface of the metal plate and push it into the boss cavity until the boss cavity is completely filled to complete the boss forming;

[0026] 4) Control the upper die fixing plate to loosen and remove the metal plate to obtain the metal plate with the boss formed.

[0027] Preferably, in step 3), the moving direction of the shovel needle is parallel to the surface of the metal plate or obliquely upward or obliquely downward.

[0028] The present invention forms a boss on the surface of a metal material by die stamping. Compared with machining, the forming process is not only simple and efficient, but also low in cost, avoiding a large amount of metal material being wasted. Through the design of the boss cavity, it is only necessary to completely fill the boss cavity during stamping to obtain a boss of fixed shape and size, thereby ensuring the forming quality of the boss.

[0032] The bottom of the elastic pressing mechanism 3 is provided with a slide rail 9 that matches the side slide block 4.

[0033] The elastic pressing mechanism 3 is a nitrogen spring.

[0034] The bottom end of the shovel needle 6 protrudes from the bottom of the side slider 4.
