Auto hinge multi-pin simultaneous riveting die

Abstract

The invention relates to the technical field of accessory devices for semi-finished product stamping and shaping, in particular to a multi-hinge-pin simultaneous press riveting die for an automobile hinge. A semi-finished product of the multi-hinge-pin simultaneous press riveting die can be conveniently fixed during stamping, so that the use reliability and practicability are improved. The multi-hinge-pin simultaneous press riveting die comprises a placing plate, a top plate, a bottom plate, a left side plate, a right side plate, an electric telescopic rod and a pressing plate, wherein the bottom end of the pressing plate and the top end of the placing plate are connected with an upper die and a lower die correspondingly; the multi-hinge-pin simultaneous press riveting die further comprises two groups of fixing plates, two groups of first threaded pipes, two groups of first threaded rods and two groups of fixing blocks, wherein bearing seats are arranged on the inner sides of the two groups of fixing plates, ball bearings and limiting plates are arranged in the two groups of bearing seats, and blocking plates are arranged on the inner sides of the two groups of bearing seats; the multi-hinge-pin simultaneous press riveting die further comprises two groups of outer connecting columns, two groups of first sleeve springs, two groups of first telescopic pipes and two groups of inner connecting columns; and the multi-hinge-pin simultaneous press riveting die further comprises two groups of locking plates and two groups of locking spring groups.

[0002] As we all know, multi-pin simultaneous pressure riveting die for automobile hinges is an auxiliary device used in the production and processing of multi-pin automobile hinges to stamp and shape semi-finished products to make them better for subsequent processing. It is used in the field of stamping and shaping of semi-finished products It has been widely used in China; the existing automobile hinge multi-pin simultaneous pressure riveting mold includes a placement plate, a top plate, a bottom plate, a left side plate and a right side plate, and the tops of the left side plate and the right side plate are respectively connected to the bottom left of the top plate. The side and the right side are connected, the bottom ends of the left side plate and the right side plate are installed on the top of the bottom plate, the placement plate is installed on the top of the bottom plate, and the electric telescopic rod and the pressure plate are also included. The electric telescopic rod is installed at the bottom of the top plate, and the pressure plate and the electric telescopic rod The bottom output end is connected, and the bottom end of the pressing plate and the top of the placing plate are respectively connected with an upper die and a lower die; when the existing automobile hinge multi-pin simultaneous riveting mold is used, its semi-finished product is placed on the top of the placing plate, and the electric telescopic rod is connected with the outside world. The control box is electrically connected, and the electric telescopic rod is turned on to drive the upper die on the pressure plate to move longitudinally to stamp the semi-finished product and cooperate with the lower die to extrude. The electric telescopic rod is a common electrical device in the market. The repurchased instruction manual can be used after electrical connection, so I won’t repeat it here; it is found in the use of the existing multi-pin simultaneous riveting mold for automobile hinges that it cannot be conveniently fixed when the semi-finished product is punched, which leads to its reliability. poorer and less useful
