Forming die for section bar with closed section

Abstract

The invention provides a profile forming die with a closed section. The profile forming die comprises an upper sliding block, a large die handle is fixedly connected to one side of the lower surface of the upper sliding block, a pressing rod is detachably and fixedly connected to the bottom end of the large die handle, a pressing strip is detachably and fixedly connected to the lower surface of the pressing rod, and a connecting mechanism is arranged between the interior of the pressing rod and the pressing strip. According to the sectional material forming die with the closed section, a workpiece can be directly subjected to closed bending forming, the workpiece with the closed section can be directly produced due to the fact that the pressing rod and the pressing strip are arranged in the workpiece, after the workpiece is formed, the hoop is made to be away from the pressing rod under the condition that the hoop is not detached through the arranged moving and rotating mechanism, and the workpiece is not damaged. And a plurality of first bevel gears are driven to rotate at the same time through rotation of the arranged connecting mechanism and the rotating rod, so that a plurality of studs are driven to rotate at the same time through a plurality of second bevel gears, quick disassembly and assembly of the pressing strip are achieved in cooperation with threaded holes, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of forming molds, in particular to a closed-section profile forming mold. Background technique [0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a worktable and a clamping plate. The bending machine is an important equipment for bending and forming workpieces in the sheet metal industry. Parts that need to be pressed into various shapes; [0003] For some common bending parts, the cross-sectional forms are similar to V-shaped, grooved, semicircular or wavy shapes, and their cross-sectional forms are open, and the bending machine can handle these workpieces better, but for some closed Sections, such as beams with circular, mouth-shaped or rectangular sections, as the bending progresses, the die handle of the bending machine will inevitably interfere with the workpiece during bending, and there is no way to perform the final closing. processing.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a profile forming die with a closed section, which solves the problem of the existing bending machine for some closed sections, such as beams with circular, square or rectangular sections. During the bending process, the die handle of the bending machine will inevitably interfere with the workpiece during bending, and there is no way to perform the final closed processing
