Scrap-free machining technology and device for lift truck scissor arm material

Abstract

The invention discloses a scrap-free machining technology and device for lift truck scissor arm material, belongs to the technical field of cold stamping die forming. The scrap-free machining technology comprises the following steps: scissoring at a fixed size, feeding, leveling and stamping; a press, a feeder and a material frame are matched for use; the feeder is positioned between the press and the material frame; the press, the feeder and the material frame are sequentially arranged; output and input ends of the press, the feeder and the material frame are sequentially connected; the material frame is a roll fixing device; the feeder is a roll-type feeding mechanism; a material guiding roll is driven by a motor; a leveling device is arranged on the feeder. Through the scrap-free machining technology and device for the lift truck scissor arm material, scrap-free lift truck scissor arm material machining can be reazlied, good product consistency, high precision, high efficiency and other advantages can be achieved; through the adoption of a die for stamping forming, a raw material adopts a roll of which the width is equal to that of a product, so that the product quality is ensured, the production efficiency is also improved by several times and the raw material and the machining cost are reduced.

Description

technical field [0001] The invention belongs to the technical field of die forming of cold stamping parts. Background technique [0002] Steel materials account for more than 90% of the cost of stamping parts. Improving the utilization rate of raw materials is of great significance to reducing the cost of stamping parts and improving product competitiveness. [0003] At present, there are two batch production methods of blanks: single-sequence blanking production and automatic production of uncoiling pendulum shearing line. In the two methods, regardless of production efficiency or processing cost, the uncoiling pendulum shearing line is higher than the single-sequence blanking process. There are often errors in the size of the cutting material, and the scrap rate is high; the manual blanking of the blanking die requires the development of multiple sets of blanking dies, and the production efficiency is low; the automatic production of the pendulum shear on the uncoiling li...

In the past, the material sheet production method of the scissor arm of the lift truck was to cut the plate with plasma or laser. This processing method consumes a lot of materials and cannot adapt to mass production. The processing cost and raw material cost cannot be reduced, and the efficiency cannot be compared with mold production compared to
