Mechanism used for continuous milling machining of special shapes and thread shapes on inner and outer surfaces of heads of pliers

Abstract

The invention discloses a mechanism used for continuous milling machining of special shapes and thread shapes on inner and outer surfaces of heads of pliers. The mechanism comprises a machining seat and laminated machining layers arranged on the machining seat. All the machining layers are orderly stacked from the top to the bottom and gradually protrude. To-be-machined material moves forward layer by layer from the top to the bottom. All the layers are separated to each other and movably cooperated with push-plate layers. Two sides of each machining layer are provided with limiting baffle plates. An outer milling assembly and an inner milling assembly are respectively installed on the side surface of each machining layer and above the side surface of each machining layer. Each outer milling assembly and each inner milling assembly are used for a plier head outer side surface special-shape mechanism and a plier head inner side surface special-shape mechanism. Tail ends of the push-plate layers are connected with push rods, below which push-rod support seats are arranged. The invention is intended to providing the mechanism used for continuous milling machining of special shapes andthread shapes on inner and outer surfaces of heads of pliers which facilitates machining bodies of pliers, reduces machining procedures and is convenient for automated machining and feeding. As a result, speed and efficiency is increased while cost is lowered.

Description

technical field [0001] The invention belongs to the field of hardware tool manufacturing, and relates to a processing device for pliers, in particular to a mechanism for continuous milling processing of special-shaped teeth on the inner and outer sides of the pliers head. Background technique [0002] Pliers are a hardware tool that is widely used, and the head part of the pliers is the main working element of the pliers, which is used to cut electric wires, iron wires or thin iron sheets. The functional area of ​​the pliers head generally includes the following elements: inner cutting edge, outer cutting edge, square mouth, grinding disc, such as Figure 1-Figure 2 As shown, the pliers body 80 is composed of two symmetrical halves of the left and right centers, which respectively include a pliers head 81 and a pliers handle 82; on the pliers head 81, an outer cutting edge 802, an inner cutting edge 803 and Square opening 804, and grinding disc 801 for assembly.

AI Technical Summary

Problems solved by technology

[0003] In the existing pliers head processing technology, when manufacturing pliers, the four elements on the pliers head are completed by two processes and divided into eight processing stations, and the left pliers body is clamped four times and processed four times. station; the right pliers body has four clamping and four processing stations; and the existing technology is mostly manual clamping, resulting in low production efficiency and high labor intensity

[0004] In addition, during the processing of the pliers body, the surface, shape and deburring of the inner and outer heads of the pliers head 81 need to be machined, shaped and deburred. The traditional method is to clamp and process one by one, which is time-consuming and laborious, and the processing efficiency is low.

[0005] The reason is that, due to the complex structure of the existing pliers, they are generally mixed together after the blanks are formed, and they are not stacked in rows in order. Firstly, part of the time is wasted in processing and finding materials, and secondly, due to inconsistent feeding, there is no automatic processing and feeding
