Abstract

The invention discloses a vehicle door window frame fastening die structure. An upper die insert is fixedly arranged on a side of a fastening knife and comprises an upper bolster, the upper bolster is fixed on the lower portion of an upper die seat, an upright column and a fixing block are disposed under the upper bolster, the fixing block is provided with a rotating shaft via a rotating bearing, the rotating shaft is provided with a rotating block, rollers are disposed on the lower portion of the rotating block, a spring is disposed between the rotating block and the upright column, the fastening knife is fixedly arranged on the lower portion of the left side of the rotating block, and a driver is disposed on a lower die seat below the right side of the rotating block. The fastening knife rotates around the rotating bearing while moving in a perpendicular direction, the movement trace of an original fastening die main bent knife in a purely perpendicular direction is modified, accordingly, the purpose of preventing interference of parts and dies is achieved, and the vehicle door window frame fastening die structure is simple and practical in designed operation.

Description

technical field [0001] The invention relates to the technical field of stamping dies for automobiles, in particular to a fastening die structure for car door and window frames. Background technique [0002] The conventional fastening mold is composed of the main bending mechanism and the pre-bending mechanism. The working part of the main bending structure, the main machete 21 is connected on the upper mold base; the pre-bending mechanism is composed of a rocker mechanism 24 and a pre-bending knife 20, the rocker mechanism is connected on the upper mold base, and the driver 23 driving the rocker mechanism is fixed on the On the upper mold base, the pre-scimitar is connected with the rocker structure (such as figure 1 shown). When the mold is working, the main scimitar goes down with the upper mold, and the driver drives the rocker mechanism to drive the pre-scimitar to move on the lower mold 22 with an approximately horizontal arc track to complete the pre-bending process....
