Precise portable type manual sheet bending machine and operating method thereof

Abstract

The invention provides a precise portable type manual sheet bending machine. The precise portable type manual sheet bending machine comprises a base, a locating pillar and a spring. Side plates are fixedly mounted at the left side and the right side of the base through bolts. A base plate is inlaid into the upper ends of the opposite side walls of the inner sides of the two parallel side plates through grooves. According to the precise portable type manual sheet bending machine, an angle scale is provided with an edge groove and the locating pillar, the outer wall of the angle scale is provided with scales, and a pointer pointing to the angle scale is arranged in the central axis of the side wall of a bending plate; in addition, the edge groove is formed in the side wall of the curved surface of the angle scale; when the upper end of the locating pillar abuts against the angle scale, the spring is in the compressed state, and it is guaranteed that the locating pillar can be located inthe edge groove all the time; when passing through an insertion hole, the locating pillar can be precisely inserted therein for locating; and the precise portable type manual sheet bending machine isapplicable to sheet bending operation in a family style small factory, low in cost and high in product precision.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and manufacturing, and more specifically relates to a precise and convenient manual thin plate bending machine. Background technique [0002] The bending machine is a machine capable of bending thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is composed of a seat shell, a coil and a cover plate, the coil is placed in the depression of the seat shell, and the top of the depression is covered with a cover plate. The bending machine is an important equipment for bending and forming workpieces in the sheet metal industry. Its function is to press the steel plate into parts of various shapes according to the process requirements. [0003] In a small family factory, sheet bending is a production operation of low value. If a large-scale bending ...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a precise and convenient manual thin plate bending machine to solve the problem that the thin plate bending operation in small family factories is a production operation with low value. If a large bending machine is used, the production cost is relatively high. High, and one machine corresponds to one person, the space is limited, and the simple bending device is used, it is difficult to achieve the expected accuracy of the bending angle
