Description

Bending die for metal control switch deflector rod of mower Technical Field The invention relates to the technical field of bending dies, in particular to a bending die for a metal control switch deflector rod of a mower. Background The metal control switch deflector rod of the mower is used as a key component for operation control of the mower, the structural accuracy and the mechanical property of the metal control switch deflector rod directly influence the use safety and the operation convenience of the mower, and because the deflector rod is usually required to have a specific bending angle to adapt to the installation and the control stroke of a switch, the traditional bending processing mode often has the problems of insufficient bending accuracy, easiness in rebound of a workpiece after forming, low production efficiency, more manual auxiliary links and the like, and is difficult to meet the requirements of modern mass production. In the first prior art (Chinese patent with publication number of CN208555707U and publication day of 2019-03-01), the structure is simpler, and the side buckle of the metal backboard can be prevented from being crushed by the upper die insert, the metal backboard bending die is provided with an L-shaped upper stripper plate step on the side of the upper stripper plate, and an inverted L-shaped second hanging table is arranged on the side of the upper die insert corresponding to the upper stripper plate, and in the die closing state, the second hanging table of the upper die insert can be attached to the upper stripper plate step under the thrust of the lifting ejector rod, so that the bottom surface of the upper die insert is positioned on the upper side of the side buckle of the bent metal backboard, the side buckle is prevented from being crushed in the bending process, and the lower spacer plate insert, the limiting pins and other limiting parts and corresponding mounting structures are eliminated. The bending die for machining the metal workpiece comprises a mounting plate, a push rod, a chute seat, a pushing mechanism and a placing mechanism for placing the metal workpiece, and further comprises a frame, a first automatic bending device and a second automatic bending device, wherein the first automatic bending device is used for automatically bending the metal workpiece into a U-shaped metal workpiece, the second automatic bending device is used for automatically bending the U-shaped metal workpiece placed on the first automatic bending device into a rectangular metal workpiece, the first automatic bending device comprises a first bending die and a second bending die, the second automatic bending device comprises a third bending die and a fourth bending die, the bending dies can be used for conducting combined bending according to different bending shape requirements of the metal workpiece, the rectangular metal workpiece can be bent, and the bending effect is good, so that mass production can be achieved. The prior art is in preventing that the work piece from damaging and promoting each have the emphasis in the aspect of the function diversity, but when taking the work piece, often need artifical manual follow mould die cavity to take out, not only increased operating personnel's working strength, in the process of taking moreover, if work piece and mould inner wall laminating are inseparable, still lead to work piece deformation or surface scratch easily because of exerting oneself inadequately, influence product quality, in addition, traditional bending die is after accomplishing bending operation, mould surface is easy to remain metal chip or greasy dirt, if untimely clear up, can lead to the fact adverse effect to bending precision and work piece surface quality next time, need additionally arrange clean process, whole machining efficiency has been reduced. So we propose a bending die for a metal control switch lever of a mower in order to solve the above mentioned problems. Disclosure of Invention The invention aims to provide a bending die for a metal control switch deflector rod of a mower, which solves the problems that in the prior market, when a workpiece is taken out, the workpiece is often required to be manually taken out of a die cavity, so that the working strength of an operator is increased, in the taking process, if the workpiece is tightly attached to the inner wall of the die, the workpiece is easy to deform or scratch the surface due to improper force, the product quality is influenced, in addition, after the traditional bending die finishes one bending operation, metal scraps or greasy dirt are easy to remain on the surface of the die, and if the workpiece is not cleaned timely, the next bending precision and the surface quality of the workpiece are adversely affected, and the problem that the overall processing efficiency is reduced is solved by additionally arranging a cleaning procedure. The bending die for the metal control switch deflecto
