Abstract

The invention relates to a sand seal structure for a trolley of a desktop forging furnace, which comprises a heating furnace (2), a trolley (10), a high temperature sand seal groove (3) and a high temperature sand seal cutter (5), wherein the high temperature sand seal groove (3) is embedded in the furnace wall of the heating furnace (2); the high temperature sand seal cutter (5) has a T-shaped structure; an air duct (6) is arranged under the high temperature sand seal cutter (5) and is connected with a centrifugal blower (1); the furnace wall of the heating furnace (2) under the high temperature sand seal cutter (5) is provided with a low temperature sand seal groove (9) and heat insulating cellucotton (8); a low temperature sand seal cutter (7) is arranged under the air duct (6); the low temperature sand seal groove (9) and the high temperature sand seal groove (3) are arranged in a step shape; the lower end of the low temperature sand seal cutter (7) is arranged in the low temperature sand seal groove (9); the upper part of the low temperature sand seal cutter (7) is fixedly connected with the side of the trolley (10); and the heat insulating cellucotton (8) is arranged on one side of the low temperature sand seal groove (9) close to the hearth of the heating furnace (2). By starting from modifying the sand seal structure and a mounting mode, the temperature of the bottom of the trolley is greatly reduced, and the working time of the sand seal cutters and the sand seal grooves is improved so as to prolong the service life of the trolley.

Description

(1) Technical field [0001] The invention relates to a forging heating furnace, in particular to a sand-sealing structure of a table-type forging heating furnace trolley. It belongs to the technical field of forging equipment. (2) Background technology [0002] The sand seal of the desktop forging heating furnace trolley is not easy to be tight, and the furnace bottom temperature is high, which is a common problem that is common in the forging industry and is not easy to solve. This makes the service life of the sand seal and the trolley steel structure short, the maintenance workload is large, and the maintenance cost is high. (3) Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned disadvantages, and provide a sand-sealed structure of a trolley for a desktop forging heating furnace with a tight sand seal and a low furnace bottom temperature. [0004] The object of the present invention is achieved in this way: a table...
