Die assembling structure on automatic fastening machine

Abstract

The invention discloses a die assembling structure on an automatic fastening machine, and relates to the field of precision mechanical equipment. The die assembling structure comprises an upper die device, a lower die device and a transmission device, wherein the upper die device clamps an automobile door base plate; the upper die device is pushed by the transmission device to drop down to be assembled with the lower die device; a skin is placed on a bottom die in the lower die device; ventilating holes are formed in the bottom die; a vacuum adsorption mechanism is arranged on the lower side of the bottom die; the skin is attached to the surface of the bottom die under the adsorption of the vacuum adsorption mechanism; an embedded tool set rising up from the lower side of the skin is arranged on the bottom die; and the embedded tool set wraps the skin along the edge of the skin to the automobile door base plate. The die assembling structure can meet the requirement for batch production of the automobile industry and also ensure that the flat surface and the vertical surface of a workpiece are attached firmly; no bubbles are produced between a fabric and a base material, so that the product quality is substantially improved; and according to the overall effect, the die assembling structure is compact, reasonable in layout, convenient to operate and steady, safe and reliable in operation.

Description

technical field [0001] The invention relates to the field of precision mechanical equipment, in particular to a mold clamping structure on an automatic eye-entry machine. Background technique [0002] The pressing and covering method of the traditional automobile door panel skin is as follows: two sets of power mechanisms drive a set of hemming molds to complete the horizontal and vertical movements to achieve the covering of the door panel skin. Its disadvantage is: since the profile of the car door panel trim is formed by a curved surface, the horizontal position is not the same curved surface as the next layer. Therefore, during processing, the profile of a set of molds cannot take into account the two profiles. The hemming mechanism of the automobile door panel skin in the known technology does not have a good hemming effect at this position, and air bubbles are easily generated between the horizontal plane and the skeleton interlayer. If two sets of horizontal and ver...
