A rough rolling forging machine for hardware parts

Abstract

The invention discloses a hardware rough blank roll-forging forming machine which comprises a base, a motor and a speed reducer. The motor and the speed reducer are arranged on the base. The speed reducer is connected with a spindle, and the spindle rotationally penetrates a left vertical plate and a right vertical plate which are arranged side by side in a spaced manner. A lower forging and pressing roll is fixed to the position, between the left vertical plate and the right vertical plate, of the spindle, an upper forging and pressing roll corresponding to the lower forging and pressing roll is fixed to a driven shaft arranged above the upper forging and pressing roll, is engaged with the driven shaft, and the upper forging and pressing roll and the driven shaft rotate relatively. The upper forging and pressing roll and the lower forging and pressing roll are both of a circumferential structure, cutters are fixed to the outer surface of the upper forging and pressing roll and the outer surface of the lower forging and pressing roll in the axial direction, and a forming cavity is formed in the outer circumference face between the cutters. A driven gear on the driven shaft and a spindle gear on the spindle are engaged on the outer side of the left vertical plate. According to the hardware rough blank roll-forging forming machine, material chopping operation is not needed, and the machining procedures are reduced; and raw materials are heated, chopped, discharged and formed at the same time, manpower, materials and time are saved, and the machining cost is remarkably reduced.

Description

technical field [0001] The invention belongs to the field of hardware tool processing machine tools, and in particular relates to a rolling forging machine for rough blanks of hardware parts. Background technique [0002] Pliers are a hardware tool that is widely used, and the cutting edge on it is the main working element of the pliers, which is used to cut wires, iron wires or thin iron sheets, etc., which brings great benefits to people in daily work and life. Greater convenience. [0003] In the existing pliers processing process, the material is first blanked, then split, then formed into a rough billet, and then precision forged. Such a process is long, time-consuming and labor-intensive, and there are more processing wastes, wasting materials, resulting in higher processing costs. [0004] For mature hardware tools, the price is relatively low. How to reduce processing loss, improve product quality and reduce processing costs are important goals for all processing m...

AI Technical Summary

Problems solved by technology

[0006] At present, the rough blank forming process in the forging industry is: 1) raw material cutting and blanking; 2) heating; 3) splitting; 4) air hammer forging and forming, there are 4 processes in total, the production process cycle is long, and the previous process is not completed. The first process cannot be carried out; the use of raw materials is generally long carbon steel bars. When cutting raw materials, in order to facilitate subsequent processing, there is generally a large processing allowance, so in the subsequent forging process, it will become waste products, thus causing more waste of materials;

[0007] In the process of air hammer forging, the impact of air hammer forging will cause a lot of noise, and air hammer forging takes a long time, which is not conducive to rapid production

[0008] In addition, for the operators, each of the four processes must be manually operated by one person, often due to the inconvenience caused by the inability to produce due to the lack of one worker, there is indeed a need for improvement
