Furnace tube rotating and intermittent feeding type placement rack

Abstract

The invention discloses a furnace tube rotating and intermittent feeding type placement rack. A power source B is arranged at the lower left portion of the placement rack. The placement rack is composed of a rear guiding section on the left side, a middle placement section in the middle and a front guiding section on the right side. The middle placement section is provided with supporting sheets which are symmetrically arranged front and back. The supporting sheets are all distributed in the X-axis direction. A plurality of bearing pedestals are arranged on the tops of the supporting sheets at equal intervals. The left end and the right end of the supporting sheet B are each provided with a supporting frame. Bearing pedestals are arranged on the tops of the supporting frames. The bearing pedestals on the top of the supporting sheet C are higher than those on the top of the supporting sheet B, and the bearing pedestals on the top of the supporting sheet C and the bearing pedestals on the top of the supporting sheet B are arranged in a spaced mode. A supporting carrier roller sheet is arranged in the middle of the middle placement section. Through rotating and intermittent forward feeding of furnace tubes, the furnace tubes can be properly supported on the placement rack, are evenly cooled in the whole-length direction, and rotate ceaselessly around the axes in the cooling process, deformation is reduced, and the quality of the furnace tubes is improved.

Description

technical field [0001] The invention belongs to the field of centrifugal casting process equipment, in particular to a furnace tube rotation and intermittent feeding type display rack. Background technique [0002] After the centrifugal casting furnace tube is pulled out from the mold cylinder, it needs to be placed on a rack to cool down, and then shot blasting is performed. The furnace tube has certain roundness and straightness requirements. The furnace tube rack currently used in production is just an ordinary frame welded by channel steel, which has the following defects: 1), the furnace tube is placed statically on the rack, and only two ends and There are three supports in the middle part. Since the furnace tube is slender, the temperature is about 600°C to 700°C when it is just pulled out, and the rigidity is poor. After standing on such a shelf for a period of time, it will bend down due to gravity; 2 ), the heat dissipation speed is fast at the contact between the...

Problems solved by technology

The furnace tube rack currently used in production is just an ordinary frame welded by channel steel, which has the following defects: 1), the furnace tube is placed statically on the rack, and only two ends and There are three supports in the middle part. Since the furnace tube is slender, the temperature is about 600°C to 700°C when it is just pulled out, and the rigidity is poor. After standing on such a shelf for a period of time, it will bend down due to gravity; 2 ), the heat dissipation speed is fast at the contact between the furnace tube and the placement rack, resulting in uneven cooling and shrinkage throughout the entire length, which will aggravate the bending deformation of the furnace tube; 3), the placement rack needs to be manually pushed forward sequentially. Let the furnace tube enter the shot blasting process, and also make room for the next furnace tube to be pulled out, and the operation efficiency is low
