Automatic discharging and nail threading device applied to coaming box assembly

Abstract

The invention provides an automatic discharging and nail threading device applied to coaming box assembly, and relates to the field of hinge production. The automatic discharging and nail threading device comprises a bottom plate, and an automatic needle discharging and perforating assembly are arranged on the top of the bottom plate. According to the device, a driving wheel is driven to rotate through an output shaft of a motor, a rotating rod is driven to rotate through a belt, two material stirring cams are further driven to rotate, and therefore long needles in a needle threading hopper can be discharged into the bottom of the needle threading hopper to be sorted and finally discharged into needle sowing pieces at the bottom of the needle threading hopper. The long needles are discharged into a needle punching track of a needle punching plate through forward pushing of the needle sowing piece, a die is pressed downwards through an oil cylinder, the rear ends of the long needles are bent, after a bending upper die returns, the bent long needles are punched into two hinges through a punch, and the long needles in irregular shapes are automatically sorted and conveyed through the needle threading hopper and the material stirring cams which are specially designed. Through the specially-designed needle sowing pieces, automatic feeding into the needle punching track is achieved, and the long needles are precisely punched into the position between the two hinges through a positioning fork.

Description

technical field [0001] The invention relates to an automatic blanking and needle threading device, in particular to an automatic blanking and nail threading device applied to the assembly of a coaming box, and belongs to the technical field of hinge production. Background technique [0002] Hinges are what we often call hinges and door hinges. The simplest hinge is connected by two patches, and the connection is connected by an iron bar through machining. The connected patches can move freely, and holes are punched on the two patches respectively, one is fixed on the wardrobe door, and the other is fixed on the side of the wardrobe, so that the wardrobe door can be opened and closed freely, which is convenient for opening. [0003] In the production of hinges, it is necessary to use mechanical equipment to process and produce the hinges. However, in the existing technology, the long needles in the hinges cannot be automatically sorted and blanked, and cannot be automatically...
