Technical Field

[0001] The utility model relates to the technical field of stamping anti-jumping, in particular to a stamping anti-jumping material mechanism. Background Art

[0002] Cold stamping is a processing method that applies pressure to materials on a press using a die at room temperature to cause separation or deformation, thereby obtaining workpieces with a certain shape, size, and performance. During high-speed blanking with a progressive die, the waste chips that enter the die cavity of the concave die are carried out of the die surface by the punch, resulting in the phenomenon of material jumping. Its existence can damage the strip or terminals, thereby affecting the quality of the products, shortening the service life of the die, and reducing production efficiency.

Detailed Embodiment

[0016] The following further describes the detailed embodiment of the present invention with reference to the drawings.

[0017] As Figures 1-4 shown, a stamping anti-jumping material mechanism includes a material receiving funnel 4. A housing 5 communicating with the material receiving funnel 4 is arranged at the upper end of the material receiving funnel 4. A compressible sealing layer 6 is arranged inside the housing 5. The upper surface of the sealing layer 6 extends beyond the upper end surface of the housing 5. The sealing layer 6 is connected to the material receiving funnel 4 in a communicating manner. A material conveying pipe 7 is arranged at the lower end of the material receiving funnel 4. The material conveying pipe 7 is arranged obliquely. An L-shaped clamping plate 8 is further included. An inclined surface for placing the material conveying pipe 7 is provided on one side of the clamping plate 8. A movable plate 9 is arranged at one end of the clamping plate 8. The material conveying pipe 7 is fixedly connected to the clamping plate 8 and the clamping plate 8 is fixedly connected to the movable plate 9 through bolts. A connecting groove 10 is arranged at the lower end of the material conveying pipe 7. A sleeve 11 is rotatably connected to the connecting groove 10. A vacuum cleaner 12 is further included. A suction pipe 13 is arranged at the suction end of the vacuum cleaner 12. One end of the suction pipe 13 is threadedly connected to the sleeve 11.

[0018] The stamping device includes main components such as a base, a power unit, a stamping table 1, a vertical plate 2, an upper die, a lower die 3, and a punch. In the drawings, only the closely related stamping table 1, vertical plate 2, and lower die 3 are shown.

[0019] When installing this anti-jumping material mechanism, first fix the feeding pipe 7 to the clamping plate 8 through bolts. After the feeding pipe 7 is fixed, the upper end face of the receiving funnel 4 is parallel to the lower die 3. Then pass the clamping plate 8 through the two vertical plates 2, and at the same time, one end of the clamping plate 8 is stuck on one side of the stamping table 1. After the placement of the clamping plate 8 is completed, connect the movable plate 9 and the clamping plate 8 through bolts. After the movable plate 9 and the clamping plate 8 are connected through bolts, there is a gap between the movable plate 9 and the clamping plate 8, so that the clamping plate 8 and the movable plate 9 can be stably installed on the vertical plate 2 and the stamping table 1. When the installation of the clamping plate 8 is completed, the sealing layer 6 is located directly below the lower die 3, and the sealing layer 6 is in a compressed state, which is convenient to improve the sealing performance between the sealing layer 6 and the lower die 3. The inner surface of the sleeve 11 is provided with internal threads, and the outer surface of one end of the dust suction pipe 13 is provided with external threads. The dust suction pipe 13 is threadedly connected with the sleeve 11.

[0020] After the installation of the receiving funnel 4 and the connection between the dust suction pipe 13 and the sleeve 11 are completed, start the vacuum cleaner 12. During the stamping process of the stamping device, the waste chips enter the lower die 3 under the action of the punch. At the same time, under the strong suction of the vacuum cleaner 12, the waste chips can enter the receiving funnel 4 through the lower die 3 and continue to fall into the feeding pipe 7. The feeding pipe 7 is inclined, so as to avoid the accumulation of waste chips in the receiving hopper and the feeding pipe 7, which is beneficial for the vacuum cleaner 12 to quickly suck out the waste chips from the feeding pipe 7, thus avoiding the occurrence of waste chip jumping.

[0021] Furthermore, grooves are respectively formed on both sides of the clamping plate 8, and springs 14 are arranged inside the grooves. One end of the spring 14 is provided with a contact plate 15. When the clamping plate 8 enters between the two vertical plates 2, when the distance between the two vertical plates 2 is greater than the width of the clamping plate 8, the clamping plate 8 makes the contact plate 15 keep continuous contact with the vertical plate 2 through the arranged spring 14, so as to improve the position stability of the clamping plate 8 between the two vertical plates 2 and avoid the situation that the position of the clamping plate 8 moves greatly between the two vertical plates 2, ensuring that the receiving funnel 4 can always maintain good cooperation with the lower die 3.

[0022] Furthermore, one end of the contact plate 15 is set to be arc-shaped. When the clamping plate 8 is pushed into the two vertical plates 2, the arc-shaped end of the contact plate 15 first contacts one end of the vertical plate 2, and the vertical plate 2 will squeeze the contact plate 15 through the arc-shaped end of the contact plate 15, so that the spring 14 is compressed. After the spring 14 is compressed, the clamping plate 8 and the contact plate 15 completely enter between the two vertical plates 2. Through the elastic force provided by the spring 14, the installation stability of the clamping plate 8 between the vertical plates 2 can be improved.

[0023] Further, a compressible shock-absorbing layer 16 is provided on one side of the clamping plate 8. During the stamping process, the vibration of the equipment will be transmitted to the clamping plate 8 and the movable plate 9, and the bolt connection between the movable plate 9 and the clamping plate 8 is prone to looseness. By providing the shock-absorbing layer 16, the loosening of the bolts can be slowed down, so that an effective connection can be maintained between the clamping plate 8 and the movable plate 9 for a long time.

[0024] Further, the material receiving funnel 4 is rotatably connected to the material conveying pipe 7. The material receiving funnel 4 can rotate on the material conveying pipe 7, so that the material receiving funnel 4 can cooperate with various types of lower dies 3, thereby improving the applicable range of the anti-jumping mechanism.

[0025] This kind of stamping anti-jumping mechanism can quickly suck the waste chips punched out by the punch from the lower die 3 through the vacuum cleaner 12, thereby preventing the punch from bringing the waste chips from the inside of the lower die 3 above the lower die 3, protecting the stamping device, ensuring the quality of the product, guaranteeing the continuous production, and improving the production efficiency.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.
