At present, the processing method of closed rivets is: in the production process, the nail shell is usually set on the nail mandrel by special stretching equipment and stretched to a certain extent, and then the semi-finished product processed in the previous step is placed on the The shaping process is carried out on two sets of equipment. Since this processing method needs to be processed on two different sets of equipment, not only is it difficult to improve the production efficiency, but also when changing the processing equipment, it is necessary to replace and adjust the mold, and it is difficult to improve the quality of the product. ensure

Embodiment Construction
[0019] The processing method of the double-station closed rivet first uses the feeding mechanism to synchronously send the nail core and the nail shell to the position of the stretching forming mechanism. The upper drawing die punch of the mechanism is the upper station. Insert the nail core into the nail shell and then perform the stretching action with the cooperation of the upper drawing die base. After the stretching is completed, the upper drawing die punch returns, and then the The upper pushing thimble of the pushing mechanism pushes out the stretched material. At this time, the pliers of the traversing transfer mechanism move up to clamp the material pushed out by the upper pushing thimble. After the pushing operation is completed, the traversing transfer mechanism will The clamped material moves down, and then the punch of the lower forming die of the stretch forming mechanism, that is, the lower station, punches the material into shape under the cooperation of the low...

The invention discloses a processing method for closed rivets on double stations. The processing method includes that firstly, an feeding mechanism feeds rivet cores and rivet shells into a position of a stretching and forming mechanism synchronously, stretching movements are performed, and materials are pushed out; at the moment, a pincers body of a cross-type shifting mechanism moves upwards to clamp materials pushed out by an upper material pushing thimble to move downwards, and then punching and forming are performed; and meanwhile, the cross-type shifting mechanism moves upwards after unloading the materials, a lower material pushing thimble of a material pushing mechanism pushes the punched and formed materials to be loaded to acquire products after stretching and forming operations are simultaneously completed by a lower forming die punch, namely a lower station, and a upper stretching die punch, namely an upper station. The processing method has the advantages that two procedures of upper station stretching and lower station forming are connected organically, and ingenious joint between the procedures is achieved, so that production efficiency is greatly improved, and stability of product quality is effectively guaranteed.
Description
technical field [0001] The present invention relates to the technical field of rivet processing methods, more specifically to the technical field of closed rivet processing methods. Background technique [0002] Rivets are mainly used in the fastening field of manufacturing industries such as various metal sheets and pipes, and are currently widely used in the assembly of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It has high riveting firmness and high efficiency, and is very convenient to use. At present, the processing method of closed rivets is: in the production process, the nail shell is usually set on the nail mandrel by special stretching equipment and stretched to a certain extent, and then the semi-finished product processed in the previous step is placed on the The shaping process is carried out on two sets of equipment. Since this processing m...
