Pressing control mechanism and pressing equipment

Abstract

The invention provides a pressing control mechanism. The pressing control mechanism comprises a lifting frame, a control assembly and a lifting rod, and is characterized in that the control assembly comprises at least four jacking mechanisms. Each of the at least four jacking mechanism comprises: a fixed seat, which is fixedly connected with the lifting frame; a balancing seat, wherein a first sliding mechanism is arranged on the side, facing the fixed seat, of the balancing seat, the fixed seat is connected with the balancing seat through the first sliding mechanism, the fixed seat and the balancing seat can move relative to each other through the first sliding mechanism, and the bottom of the balancing seat is connected with a hanging rod and fixedly connected with a male die assembly through the hanging rod; and an air cylinder, which is arranged on the fixed seat, wherein a piston rod of the air cylinder faces upwards, the tail end of the piston rod makes contact with the balancingseat, and when air pressure in the air cylinder is increased, the piston rod extends to jack the balancing seat. By using the pressing control mechanism, the adverse effect of uneven glass pressing on a glass molded surface can be improved.

Description

Technical field: [0001] The invention relates to the field of vehicle glass production equipment, in particular to a pressing control mechanism and pressing equipment. Background technique: [0002] With the development of the modern automobile industry, the front windshield glass of the car tends to be more streamlined, that is, the front windshield glass must have the characteristics of large spherical surface, deep curvature, and small radius of curvature at the corners. In the technological process, only the traditional self-weight forming method is still used. The specific method is to place the glass on the baking-bending self-weight forming mold (the mold is composed of a frame with a streamlined spherical frame, and the four corners of the frame are equipped with adjusting curvature and curvature). The counterweight. Send the glass together with the self-weight molding mold into the baking furnace for heating. When heated to the softening point of the glass, the glas...

AI Technical Summary

Problems solved by technology

For the current glass pressing molding method, there are still some problems. For example, due to the precision of the mold during molding, there are inevitably some dimensional errors between the concave and convex molds that are pressed, resulting in uneven local pressure on the glass and warping on the molded surface. At this time, a certain degree of overpressure is required to ensure that each side and corner is fully suppressed, and due to the difference in the degree of suppression of each side and corner, it is easy to cause some sides and corners to be excessively suppressed during overpressure

Even if the error of tooling or mold can be reduced by adjustment, due to the variety of vehicle glass, it needs to be adjusted every time the mold is replaced, and the precision of the mold will inevitably be lost with the use of production, and the error of the shape is not fixed. Changed, bringing difficulty to adjustment
