A multi-station jump riveting mechanism, jump riveting machine and chain assembly and processing line

Abstract

The invention discloses a multi-station jumping riveting mechanism, a riveting machine and a chain assembling processing assembly line. The multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line comprises an upper die mechanism and a lower die mechanism arranged at the lower end of the upper die mechanism, a riveting mechanism is arranged between the upper die mechanism and the lower die mechanism, and a chain jumping mechanism is arranged middle of the jumping riveting mechanism; the jumping riveting mechanism comprises a height adjusting rod of an exposed head pressing block, an upper exposure head pressing block arranged at the lower end of the height adjusting rod of the exposed head pressing block and fixedly connected with theheight adjusting rod of the exposed head pressing block, and a lower exposure pressing block arranged at the lower end of the upper pressing block. According to multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line, a novel shaping mechanism is arranged and is used for chains and riveting heads, the outer section and outer width of chainsare shaped through pressure coordination of the upper pressing block and the lower pressing block, so that the pressure load of a chain assembling machine is reduced, assembling precision of the chain assembling machine is further improved, and shaping precision of the outer section and the outer width is improved; and the multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line has the advantages that the operation difficulty is reduced, the working efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention relates to a multi-station riveting jump mechanism, a riveting jumper and a chain assembly and processing line. Background technique [0002] The existing automatic chain production process adopts the working mode of riveting first and then dismantling the joints. However, the riveting mechanism of the existing riveting machine will perform riveting on all the chains that have passed through the joints, which will lead to problems faced by the dismantling step. It is a pin shaft that has already been riveted, and it is difficult to disassemble the joints. It not only requires high strength of the punching pin, but also seriously affects the service life of the punching pin. Both the shaft and the chain plate are damaged due to deformation and cannot be reused. [0003] Publication No. 203830646, a jump riveting machine for chain riveting heads, has solved the above-mentioned problems, including a frame on which a jump riveting mechanism ...

Problems solved by technology

[0002] The existing automatic chain production process adopts the working mode of riveting first and then dismantling the joints, but the riveting mechanism of the existing riveting machine will do the riveting process on all the chains passing through, which will lead to the problems faced by the dismantling step. It is a pin shaft that has already been riveted. It is difficult to dismantle the joints. It not only requires high strength of the punching pin, but also seriously affects the service life of the punching pin. Shafts and chain plates are damaged due to deformation and cannot be reused

[0003] Publication No. 203830646, a jump riveting machine for chain riveting heads, has solved the above-mentioned problems, including a frame on which a jump riveting mechanism and a rivet jumper for transferring the chain to be processed to pass through the jump riveting mechanism have been solved. Chain-running mechanism; the jump riveting mechanism includes upper and lower mold mechanisms correspondingly arranged up and down, the lower mold mechanism includes a lower mold base and a lower die, the lower mold base is fixed relative to the frame, and the lower die is fixedly arranged on the lower die On the base; the upper mold mechanism includes an upper mold base, an upper die, and an upper die drive mechanism for driving the upper die to slide laterally relative to the upper die base. The upper die base can be set to slide up and down relative to the lower die base through a sliding fit mechanism On the frame, the upper die is set under the upper die base so that it can slide laterally relative to the upper die base through a sliding fit mechanism, but this equipment ignores the large pressure load of the chain assembly machine during the chain processing process, which makes the chain assembly machine During the assembly process, the buckling force on the outer section and outer width of the chain is different, resulting in different precision between the front and back of the chain
