Description

Following type rod beating reset mechanism Technical Field The utility model relates to the technical field of manufacturing of stamping die technology, in particular to a follow-up type rod beating reset mechanism. Background When processing the bolt among the prior art, beat the stick and have the function of bearing and pushing out the die cavity with the bolt, beat the stick and beat and overlap for ordinary shaft hole cooperation between the, when producing the bolt of short specification, can normally produce, nevertheless when processing the extension bolt of little specification, beat the length of stick and also add thin and extension, consequently often can appear beating the cracked phenomenon of stick, cause to pound the car, damage the mould, influence production efficiency, the mould life-span is low. In order to achieve the above purpose, the application provides a rod assembling die, which comprises a die core, a rod and a rod sleeve, wherein the two axial ends of the die core are a forming end and a guiding end, the die core is provided with a die cavity penetrating through the forming end and the guiding end, the forming end is used for bolt forming, the rod is inserted into the die cavity from the guiding end, the rod moves towards the forming end, the bolt is pushed to leave the die cavity, the rod is provided with a guide key extending along the axial direction, the rod sleeve is sleeved outside the rod, the inner wall of the rod sleeve is provided with the guide key groove, the guide key groove is matched with the guide key so that the rod moves in the rod sleeve, the technical scheme of [0016]1. The rod and the rod sleeve are respectively provided with the guide key groove and the guide key groove which are matched with each other, and the rod sleeve move in the rod sleeve when the rod moves in the rod sleeve, the guide key groove and the guide key groove are arranged in the guide key groove, and the sliding effect of the rod sleeve is improved, and the impact resistance is improved, and the movement stability of the die is improved. In the practical application process, when the product to be processed is pushed into the die, the product to be processed pushes the ejector rod, and the ejector rod pushes the rod to return, because the rod is matched with the rod sleeve through the shaft hole, the rod has certain friction force, if the product to be processed is thicker and shorter, the rod cannot be deformed when being pushed, but if the product to be processed is slender, the rod is pushed, under the action of friction force, and the slender product to be processed can have the risk of deformation. Although the comparison document (patent publication number: CN 217617248U) improves the stability of the rod moving by respectively processing keys and key grooves on the rod and the rod sleeve and guiding the rod moving, the device needs to respectively process the keys and the key grooves on the rod and the rod sleeve, and is labor-consuming and time-consuming, so that the structure needs to be improved. Disclosure of Invention The utility model aims to provide a follow-up rod beating reset mechanism so as to solve the problems in the background technology. In order to solve the technical problems, the follow-up type rod beating reset mechanism is characterized by comprising a rod beating for pushing a mould ejector rod, wherein a shaft shoulder is arranged on the rod beating, a first hook is arranged on the shaft shoulder, one end of a reset spring is hung on the first hook, the other end of the reset spring is hung on a second hook of a mould body, and a stop screw for limiting the rod beating retreating position is arranged on the mould body. Compared with the prior art, the utility model has the advantages that the reset spring is arranged on the beating rod, so that the beating rod can return to the ground under the action of the reset spring after pushing the product, and when the product to be processed is pushed into the die, the beating rod does not need to be pushed, and particularly, the slender product to be processed does not have the risk of deformation. As an improvement of the utility model, the stop screw is fixed by a stop nut. The design is selected to have the purpose that the stop screw rod plays a role in limiting the terminal position when the stick is reset. As an improvement of the utility model, the stop screw is an oil buffer. The design is selected for the purpose that the return speed of the beating rod is accelerated due to the addition of the return spring, and the oil pressure buffer is arranged for reducing vibration and noise. As an improvement of the utility model, the head of the stop screw is provided with a buffer rubber pad. The design is chosen for vibration and noise reduction.
