TECHNICAL FIELD

[0002] In the field of metal processing, with the continuous development of manufacturing industry, the requirements for production efficiency and cost control of parts are increasingly improved. Efficient and low-cost production methods can significantly improve the market competitiveness of enterprises and promote the development of the entire industry. Under the trend of automatic production lines, how to realize the integration of multiple processes and improve production efficiency has become a key problem to be solved in the field of metal processing.

[0003] In the traditional production process, the assembly work of stamping parts, spring sheets and silver contacts usually needs to be completed by multiple independent processes. These processes include stamping, twice riveting, cleaning and packaging, etc. In actual operation, each process needs separate equipment and manual participation. Stamping process needs special stamping equipment and workers for operation, and riveting process also needs corresponding riveting equipment and workers. This dispersed production method makes the entire production process long and complex.

[0004] At present, due to the need for multiple independent processes, the production efficiency is very low, and a large amount of manual participation is needed. This not only increases the production cost, but also greatly increases the risk of product failure. In the process of manual operation, some human errors are inevitable, which affects the quality and stability of the product. In addition, usually multiple strips are conveyed along the feeding machine, the height of the strip and the machining end face of the lower die seat cannot be controlled, which easily causes machining precision error and the stamping parts cannot produce the expected effect; in the riveting stage, the silver contact rivet often has too fast, too slow or blocked transmission, which will also cause the overall production to be scrapped and lost.

This is because the structure design enables each process to be orderly carried out in the mold, avoiding the cumbersome operation of multiple independent processes in the traditional process.

[0054] Referring to Figure 2 , Figure 3 , Figure 4As shown, the feeding mechanism includes a first feeding mechanism 301, a second feeding mechanism 302, and a third feeding mechanism 303. The first feeding mechanism 301 includes a feeder 3011, a guide column 3012, and a positioning block 3013. The feeder 3011 is installed on one side of the input end of the lower die seat 2 and is used to drive the transmission of the stamping part tape. The feeder 3011 can be a common roller type feeder 3011 that moves the tape by rotating the rollers. The guide column 3012 is installed on the end face of the lower die seat 2. The middle section of the guide column 3012 is used to limit the tape. The guide column 3012 is composed of multiple column structures 3014. Each column structure 3014 is arranged in a stack from bottom to top. The column structure 3014 has a column part 30141, a recess part 30142, and a connecting part 30143.

This detachable column structure 3014 design allows the guide column 3012 to be adjusted according to stamping part tapes of different heights. For example, when the stamping part tape is thick, the number of column structures 3014 can be increased, and vice versa. The positioning block 3013 is installed on both sides of the tape to further fix the position of the tape and prevent the tape from shifting during transmission. The positioning block 3013 can be a block structure made of metal and is fixed to the lower die seat 2 by bolts. The combination of multiple components can stably transmit the No. 1 tape and ensure accurate transmission according to the predetermined first transmission trajectory 31.

[0055] Referring to Figure 2 As shown, the second feeding mechanism 302 is used to transmit the No. 2 tape. It can adopt a similar structure as the first feeding mechanism 301 or be appropriately adjusted according to the characteristics of the No. 2 tape. For example, if the No. 2 tape is thin and flexible, a belt type feeding mechanism can be used to move the tape by friction. The No. 2 tape is transmitted along the second transmission trajectory 32, forming a cross-shaped double tape track with the first transmission trajectory 31, realizing synchronous processing of stamping parts and pellets.

[0056] The third feeding mechanism 303 is used to transmit silver contact rivets and includes a vibration disc 3031, a conveying track 3032, a spacer 3033, and an adjusting piece 3034.

The vibration disc 3031 can be an electromagnetic vibration disc 3031 that vibrates the rivets through electromagnetic force to achieve sorting and orientation. The conveying track 3032 is installed on the vibration disc 3031 and is used to guide the transmission of the silver contact rivets.

[0057] Referring to Figure 5As shown, the spacer 3033 is used to separate the silver contact rivets, so that each individual output, the spacer 3033 includes a barrier block 30331 arranged on the conveying track 3032, a gear 30332 installed on the barrier block 30331, a toothed plate 30333 engaged on the gear 30332 and a cylinder 30334 installed on the toothed plate 30333, the toothed plate 30333 slides on the outer surface of the conveying track 3032. In the embodiment, the double-sided toothed plate 30333 is preferred, each side is engaged with the gear 30332 to drive, the barrier block 30331 is in a crescent structure, when the piston rod of the cylinder 30334 extends, it drives the toothed plate 30333 on the conveying track 3032 to move, at the same time, it drives multiple gears 30332 to rotate synchronously, the barrier block 30331 fixed with the gear 30332 rotates together, so that the barrier block 30331 in the transmission track 3 is opened at intervals, facilitating the uniform movement of the rivets along the conveying track 3032. The cylinder 30334 reciprocatingly drives the toothed plate 30333, conversely, when the cylinder 30334 retracts, the toothed plate 30333 moves along the axis of the piston rod of the cylinder 30334, the toothed plate 30333 drives the engaged gear 30332 to rotate, the barrier block 30331 approaches each other, so as to realize the closing of the conveying track 3032, and achieve the purpose of uniform interval transmission of the silver contact rivets.

[0058] Referring to Figure 6 As shown, the adjusting member 3034 is used to adjust the transmission of silver contact rivets with different diameters along the conveying track 3032, the adjusting member 3034 includes clamping strips 30341 symmetrically installed in the conveying track 3032, a bidirectional screw 30342 penetratingly arranged on the clamping strips 30341 and an adjusting knob 30343 installed on the end of the bidirectional screw 30342 penetrating the conveying track 3032. By rotating the adjusting knob 30343, the bidirectional screw 30342 rotates, so that the clamping strips 30341 approach or move away from each other, thereby adjusting the gap between the clamping strips 30341 to adapt to silver contact rivets with different diameters. The side wall of the clamping strip 30341 abuts against the end of the silver contact rivet, the cross section of the clamping strip 30341 is small at the top and large at the bottom, the cross sections of the two clamping strips 30341 can be V-shaped, inverted trapezoidal or U-shaped, which can better cooperate with the silver contact rivet to ensure stable transmission.

[0059] The punching mechanism 4 is installed on the first transmission track 31 along its transmission direction, and is used for sequentially performing pre-punching processing on the surface of the stamping part material belt on the first material belt. The punching mechanism 4 can be a common punch and die combination structure. The punch on the upper die holder 1 moves downward under the action of pressure, penetrates through the stamping part material belt, and completes the punching operation under the cooperation of the die.

[0060] The cutting mechanism 5 is installed along the transmission direction of the second transmission track 32, and is used for equidistant blanking of the second material belt.

[0062] Referring to Figure 7 As shown, the bending mechanism 7 is installed at the output end of the lower die seat 2, and is used for bending the material belt on the second transmission track 32 with the lower die seat 2 to form a bending angle. The bending mechanism 7 includes a bending block 71 and an auxiliary block 72, the bending block 71 is arranged on one side of the first transmission track 31, and the auxiliary block 72 is installed on the other side of the first transmission track 31.

The auxiliary block 72 forms an inclined surface towards one side of the bending block 71, and the slope of the inclined surface gradually decreases along the transmission direction of the first transmission track 31. This structure design can gradually change the angle of the material belt during the bending process, and avoid damage to the material belt caused by excessive bending.

[0063] The implementation principle of the embodiment is that: by integrating multiple processes such as feeding, punching, cutting, riveting and bending in the same mold, the feeding mechanism can adapt to stamping part material belts of different heights and control the interval transmission of rivets, ensure the smooth progress of each process, the punching mechanism 4, the cutting mechanism 5 and the riveting mechanism 6 process the material belt in turn, and finally the bending mechanism 7 completes the bending of the product, greatly shortens the process flow, improves the production efficiency, reduces the labor cost and the failure risk of the product.
