Description

Detailed Description of the Invention (Technical Field of the Invention) The present invention relates to a method for suspending a plate glass so that the plate glass is vertically carried into a heating furnace, taken out from the heating furnace in that state, and faced between the molds of a press machine. Regarding a lowering device.

(Prior Art) The conventional method for bending and forming plate glass is to transport the plate glass horizontally into a heating furnace, take it out from the heating furnace horizontally, and then press-form it horizontally between upper and lower molds. In some cases, sheet glass is carried into a heating furnace vertically, taken out of the heating furnace vertically, and press-formed vertically between left and right molds.

When bending sheet glass in a vertical position,
A hanging device is used to carry the plate glass into the heating furnace in a suspended state, and to press-form it between molds in the suspended state.

As such a hanging device, the one shown in Japanese Patent Laid-Open No. 156924/1983 is known.

That is, a turnbuckle is locked to a rack bar of a wagen rack that is movable between a heating furnace and a press bending device, a support plate is swingably attached to the lower end of this turnbuckle, and both ends of this support plate are Another support plate is swingably attached to the lower support plate, and hangers are attached to both ends of the lower support plate to form a tournament shape, so that the upper edge of the glass plate is held between the lower ends of the hangers. In order to stably support the glass plate, usually a plurality of turnbuckles are engaged with a rack bar, and a hanging tool is suspended from each turnbuckle via a support plate.

(Problems to be Solved by the Invention) As mentioned above, conventionally, in order to continuously press-form sheet glass in a vertical state, a plurality of wager racks are used, and the sheet glass is suspended and supported from each rack. There are variations in dimensions for each wagon rack, and if the plate glass is suspended and supported and exposed between the molds, the position of the mold and the plate glass will be misaligned, making it impossible to obtain a product with excellent bending accuracy.This is especially true for automobiles. The above-mentioned drawbacks become noticeable in deeply bent products such as rear windows.

Therefore, in the past, adjustments were made in the left-right direction (the length direction of the rack bar) by changing the locking position of the turnbuckle with respect to the rack bar, and in the vertical direction by operating the turnbuckle itself. The contact position between the sheet glass and the press mold is kept constant.

However, the above adjustment has to be done for each turnbuckle individually and is done manually, so there are problems that the adjustment is troublesome and time consuming, and furthermore, it is impossible to make adjustments in the front and rear directions. be.
