A continuous bending die

Abstract

The invention discloses a bending continuous die which comprises an upper die set and a lower die set. The upper die set comprises a discharging plate, and a discharging back plate, a spring, a fixed plate, a fixed base plate, an upper die base and an upper die frame which are sequentially arranged on the upper side of the discharging plate. The lower die set comprises a female die plate, and a female die base plate, a lower die base and a lower die pad which are sequentially arranged on the lower side of the female die plate. The fixed plate is provided with a plurality of pairs of upper punches. Each pair of upper punches are fixed to the fixed plate in a clearance fit mode through a circular hanging table. The portion, corresponding to each pair of upper punches, on the female die plate is provided with a sliding block. External workpiece raw materials are fed between the discharging plate and the female die plate, and are punched and formed through the upper and lower die sets, so that each pair of upper punches and the corresponding sliding block are cooperated to bend the workpiece raw materials to form workpieces, the vertical edge angle of formed workpieces is smaller than or equal to 90 degrees, automatic batch production of workpieces is achieved, and the economic benefit is good.

Description

technical field [0001] The invention relates to the field of stamping dies, in particular to a continuous bending die. Background technique [0002] The process of the development of science and technology shows that the machinery industry is an important carrier for the materialization of science and technology into productivity, and mold design and manufacturing occupy a pivotal position in the machinery industry. At present, 60%-80% of parts in electronics, automobiles, electrical machinery, home appliances and military products must be formed by molds. The high precision, high complexity, high consistency and low consumption of molded parts are unmatched by other manufacturing methods. The mold determines the quality, efficiency and development ability of the product to a large extent. [0003] For the traditional simple bending process, it is generally completed by a bending machine, and for the multi-process bending process, it is generally realized by a continuous mo...

Problems solved by technology

[0003] For the traditional simple bending process, it is generally completed by a bending machine, and for the multi-process bending process, it is generally realized by a continuous mold, so that it can be mass-produced, improve production efficiency, and reduce production costs. However, further research on the bending process found that the current On the market, the bending mainly completes the obtuse angle bending with an angle greater than 90 degrees, but for the bending process that requires a 90-degree bending process or less than 90 degrees, it is rarely realized, and often requires secondary processing to achieve it, which increases the forming process. steps, not conducive to mass production of enterprises
