Feeding-discharging mechanism of vacuum annealing furnace

Abstract

The present invention relates to a feeding and discharging device of a vacuum annealing oven, and belongs to the art field of the feeding and discharging assistant facility of the vacuum annealing oven. The feeding and discharging device comprises a pair of first tracks, a chassis of a frame, a pair of load pulley supporting devices, a power device, and a pull rod shaft, wherein the first tracks are laid on the terrace corresponding to the lower part of an oven body and paralleled with each other, and separated a certain distance; the chassis of the frame is arranged on the first tracks in the sliding way; the load pulley supporting devices used for supporting the load pulley in the oven body are arranged on the chassis with the space, the frame is linked with the an oven cover of the oven body; the power device used for drive the chassis to move along the first tracks is arranged on the frame; and the pull rod shaft used for connecting with the load pulley is also arranged on the frame. The present invention has the advantages that the front and the back movements of the chassis matched with the first tracks is ensured to be consistent but not to deviate through the laid first tracks, thereby guaranteeing the pull rod shaft to make the load pulley in the oven body keep straight line movement forever when passing in and out the oven body, and having the good centring degree. Arranging with the supporting devices can avoid the load pulley carrying the product from being sunk and distorted.

Description

technical field [0001] The invention relates to a material inlet and outlet mechanism of a vacuum annealing furnace, which is an improvement on the material inlet and outlet mechanism of a vacuum annealing furnace in the prior art, and belongs to the technical field of auxiliary material inlet and outlet facilities of a vacuum annealing furnace. Background technique [0002] As is well known to those skilled in the art, before the vacuum annealing furnace works, the product to be annealed needs to be fed (loaded) into the furnace, otherwise, after the annealing is completed, the product needs to be removed from the furnace. Figure 3 shows a purely manually operated feeding and discharging handcart, which is currently commonly used for feeding (feeding) and discharging materials such as high-temperature sintering furnaces and vacuum annealing furnaces. It is composed of a vehicle frame 1 equipped with rollers 4 at the bottom, a jack 2 arranged on the vehicle frame 1 and a pai...

AI Technical Summary

Problems solved by technology

The entry and exit handcart with the above structure mainly has the following disadvantages during use: the position of the pair of support arms 3 entering and exiting the furnace is not easy to align, and once the alignment is lacking, the product will be placed on the support arm 3 The center of gravity is not stable, not only will there be impacts and scratches on the furnace wall, which is not good for the protection of the product and the furnace, but also there is a risk of sideways collapse when it is moved out of the furnace; It is said that sinking will occur after the material is placed, which will also affect the effect of feeding and discharging, and even cause slippage during discharging, and it is difficult to achieve the ideal material level requirement when feeding
