Description

Bending mechanism
Technical field
The present invention relates to electronic component technical field of processing equipment, and in particular to a kind of bending mechanism.
Background technology
Bending mechanism is a kind of conventional mechanism of mechanical field, can carry out bending to various materials, by taking PIN needle as an example, The inside of some existing electronic components is usually required to set bending PIN needle, and PIN needle bending is generally required to pass through bending mechanism To realize.
Chinese patent literature CN203900340U discloses a kind of shearing bending mechanism, including supporting plate, bottom plate, carrier lock Tight device, product carrier, lower cutting die, riser, air cylinder fixed plate, cylinder, lifter plate, guide pillar, upper cutting die, connecting pole, binder block And electronic product;The supporting plate has two, and bottom plate is provided with two supporting plates, and the bottom plate bottom is provided with carrier locking Device, bottom plate are provided with a slotted eye, and product carrier is locked in the slotted eye on bottom plate by carrier locking device;The bottom plate On lower cutting die is installed, lower cutting die is located at the rear of product carrier;A riser is vertically installed with the cylinder bottom plate, on riser Air cylinder fixed plate is installed, the cylinder is arranged in air cylinder fixed plate;The piston-rod lower end of the cylinder is connected to lifter plate, And it is oriented between lifter plate and air cylinder fixed plate by guide pillar;Cutting die is installed below the lifter plate, led on lifter plate Cross two connecting poles and be connected to binder block, and binder block is located in front of upper cutting die;The upper cutting die bottom is by planar section and tiltedly Face packet into.Electronic product is placed on the product carrier, cylinder driving, under guide pillar guiding, lifter plate drives upper cutting die Moved down with binder block, binder block first contacts electronic product front portion and will go to push down, and then upper cutting die continues to push, and cutting die is flat thereon Face part first contacts the PIN of electronic product, and in the case where coordinating during pushing, cutting die first cuts PIN, then upper cutting die after It is continuous to push, the chamfered portion contact PIN of cutting die thereon, coordinate lower cutting die that PIN bending is completed into the action of shearing bending.
Although above-mentioned shearing bending mechanism can realize the shearing and bending to PIN needle simultaneously, due to being by upper The vertical direction motion of cutting die coordinates with lower cutting die to realize the bending to PIN needle, and the vertical direction of upper cutting die is moved to PIN Pin carries out producing larger Relative friction between meeting and PIN needle during bending, causes the coating on PIN needle surface to be worn away, PIN needle is easily damaged, and upper cutting die can only carry out the motion of vertical direction and cause the maximum angle that PIN needle is bent over to be no more than 90 Degree, bending angle scope are limited, and then when needing PIN needle being bent into 90 degree, the bounce-back that part is bent over due to PIN needle is made With so that need that PIN needle is bent into 90 degree to PIN needle progress secondary bending realization.In addition, above-mentioned shearing bending mechanism accounts for Larger with space, inconvenience, which is installed in the more station of mechanism, to be used.
