Description
Technical Field
The utility model belongs to the technical field of heat treatment process equipment, and particularly relates to a single hanging mechanism for heat treatment of a large forging in a pit furnace, which is used for heat treatment of the large forging in the pit furnace.
Background
In the prior art, the effective diameter of a used heat treatment pit furnace is about 2 meters, the maximum bearing capacity is about 20 tons, and the limitation is that only a single charging furnace can be used for producing a single product with larger diameter and heavier weight, and two types of existing single hanging heat treatment tools are provided, namely, a straight rod type product is hung through a hoisting hole, and an opposite-end headband step type product is hung through fastening of a bearing plate. Although the requirement of single production can be met by drilling a lifting hole for hanging a straight bar-shaped product, the dead weight of the product is larger, the tonnage of a special tool for hanging a plate body, a hanging plate, a hanging rod and the like is also larger, the energy loss caused in the heating process is serious, the service life of the tool is short, the production cost is high, and therefore the optimized design is carried out.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide the single-support hanging mechanism for the heat treatment of the large forging pit furnace, which solves the problems of high weight, short service life, serious energy loss in the heating process, high production cost, low heating and quenching cooling speed of the workpiece head and the like of the large forging.
In order to achieve the purpose, the technical scheme of the utility model is realized as follows: the utility model provides a large-scale forging shaft furnace thermal treatment list props up mechanism, is including the support frame of hanging that has the horizontal axle, and the both ends of hanging the horizontal axle of support frame respectively with the head end inside surface welded fastening of left bearing pole and right bearing pole, welded fastening has the both ends head of round pin axle between the tail end inside surface of left bearing pole and right bearing pole, installs the round pin axle in the hoist and mount hole that the work piece head was seted up.
Compared with the prior art, the utility model has the advantages that: through the design of the novel single-support hanging mechanism for the heat treatment of the large-scale forge piece in the shaft furnace, the problems of serious energy loss in the heating process, high production cost, low workpiece head heating and quenching cooling speed and the like caused by the large weight and short service life of the tool in the prior art can be solved, the repeated service life of the tool is greatly prolonged, the product quality is effectively improved, the operation is simple and convenient, and the production cost is reduced.

FIG. 3 is a schematic view of a hanging support frame according to the present invention.
The labels in the figures are: 1. a left load-bearing round bar; 2. a right load-bearing round bar; 3. hanging a support frame; 4. a pin shaft; 5. a boom; 6. a plate hanging body; 7. hanging the plate; 8. blocking nails; 9. and (5) a workpiece.
Detailed Description
As shown in fig. 1, in the prior art, the effective diameter of the used heat treatment pit furnace is about 2 meters, the maximum load bearing is about 20 tons, only a single product with a larger diameter and heavier weight can be produced by charging the furnace, a lifting hole is drilled on a workpiece 9, a pin shaft 4 is penetrated into the lifting hole and is fixed by a stop nail 8 for suspension, although the requirement of single production can be met, the dead weight of the product is larger, the tonnage of the adopted special tool such as a hanging plate body 6, a hanging plate 7, a hanging rod 5 and the like is also larger, the energy loss caused in the heating process is serious, the service life of the tool is short, the production cost is high, and therefore, the optimized design is carried out.
As shown in figures 2 and 3, the utility model discloses a single suspension mechanism for heat treatment of a large forging well furnace, which comprises a suspension support frame 3 with a transverse shaft, wherein two ends of the transverse shaft of the suspension support frame 3 are respectively welded and fixed with the inner side surfaces of the head ends of a left bearing round rod 1 and a right bearing round rod 2, two ends of a pin shaft 4 are welded and fixed between the inner side surfaces of the tail ends of the left bearing round rod 1 and the right bearing round rod 2, and the pin shaft 4 is arranged in a hoisting hole formed in the head of a workpiece 9. The workpiece 9 is fixed on the hanging mechanism by welding the transverse shaft of the hanging support frame 3 and the two ends of the pin shaft 4 with the full cross section of the inner side surface of each end of the left bearing round rod 1 and the right bearing round rod 2 respectively.
The method can solve the problems of serious energy loss in the heating process, high production cost, low workpiece head heating and quenching cooling speed and the like caused by large tool weight and short service life in the prior art, greatly prolongs the repeated service life of the tool, effectively improves the product quality, is simple and convenient to operate, and reduces the production cost.
Firstly, a pin shaft 4 is inserted into a hoisting hole formed in the head of a workpiece 9; secondly, placing the left bearing round rod 1 on the left side of the workpiece 9, and carrying out full-section welding on the outer surface of one side, close to the workpiece, of the end of the left bearing round rod 1 and the end, close to the left side of the workpiece 9, of the pin shaft 4; thirdly, placing the right bearing round rod 2 on the right side of the workpiece 9, and carrying out full-section welding on the outer surface of one side, close to the workpiece 9, of the end of the right bearing round rod 2 and the end, close to the right side of the workpiece 9, of the pin shaft 4; fourthly, welding the two ends of the hanging support frame 3 with the inner side surfaces of the other ends of the left bearing round rod 1 and the right bearing round rod 2 in a full-section mode respectively, and fixing the left bearing round rod 1 and the right bearing round rod 2.
