Description

Technical Field

[0001] This utility model relates to the field of heating for forging processing, and in particular to a tabletop heating furnace for forging processing. Background Technology

[0002] A tabletop heating oven typically functions by using a heat source. Its working principle is to heat the resistance band to reach a certain temperature inside the oven cavity, and use the heat energy to remove moisture from the products that are sent into the oven cavity by the trolley to achieve a drying effect, or to bring the products to a certain temperature to achieve drying, curing, aging, etc.

[0003] Heating furnaces are generally used for heating forgings, while benchtop heating furnaces are a type of large heating furnace suitable for heating large metal parts. They can accommodate large metal parts while ensuring heating temperature and heating speed. Over time, benchtop heating furnaces produce water vapor during heating, which carries impurities that adhere to the inner wall of the furnace, significantly affecting the heating speed. Furthermore, benchtop heating furnaces are large and difficult to clean.

[0004] Therefore, it is necessary to propose a benchtop heating furnace for forging to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a benchtop heating furnace for forging processing, so as to solve the problems of the heating speed being affected by long-term use of benchtop heating furnaces and the inconvenience of cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tabletop heating furnace for forging processing, comprising a tabletop heating furnace and a base plate for supporting the tabletop heating furnace, wherein two grinding rods for grinding the inner wall of the tabletop heating furnace are movably provided on the inner side of the tabletop heating furnace, and an annular plate for restricting the movement direction of the grinding rods is movably provided at the upper end of the tabletop heating furnace.

[0007] Two guide grooves are formed through the upper end of the annular plate, and a rotating shaft is fixedly provided at the upper end of the grinding rod. The rotating shaft can move inside the corresponding guide groove.

[0008] The two guide slots are arranged in a mirror image.

[0009] Preferably, two brackets are fixedly provided on the upper end of the base plate, and electric cylinders are installed on the upper ends of the two brackets. The outer side of the annular plate is connected to the corresponding brackets through a fixing mechanism.

[0010] Preferably, a transmission plate is movably provided at the upper end of the annular plate, and two translation grooves are provided at the upper end of the transmission plate, with an I-shaped rod movably provided inside the translation grooves.

[0011] Preferably, a drive motor is fixedly provided at the upper end of the I-shaped rod, and the output end of the drive motor is fixedly connected to a rotating shaft, which movably passes through the I-shaped rod.

[0012] Preferably, the outer sides of the two grinding rods are in contact with each other.

[0013] Preferably, the inner wall of the tabletop heating furnace is provided with multiple slag discharge holes for slag to fall off.

[0014] The lower end of the tabletop heating furnace is fixedly provided with a conical bottom shell, and the lower end of the conical bottom shell is fixedly provided with a slag discharge nozzle.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting the guide groove on the annular plate, the inner wall of the benchtop heating furnace can be automatically cleaned, reducing impurities on the inner wall of the benchtop heating furnace and reducing the impact of impurities on the heating of the benchtop heating furnace. It can also be used to clean larger benchtop heating furnaces more conveniently. With the setting of the slag discharge hole, only the annular inner wall of the benchtop heating furnace needs to be cleaned, thereby reducing the cleaning area.

[0017] 2. Through the cooperation of the guide groove and the transmission plate, the inner wall of the benchtop heating furnace can be cleaned when the output end of the electric cylinder extends and retracts, so that the extension and retraction of the electric cylinder are both effective and improve polishing efficiency.

[0018] 3. When the two polishing rods come into contact with each other, they can clean each other by scraping off impurities, which facilitates automatic cleaning of the polishing rods and makes them suitable for long-term use. Attached Figure Description

A slag discharge nozzle 15 is fixedly provided at the lower end of the conical bottom shell 14. The fallen impurities are discharged from the slag discharge nozzle 15. Both the slag discharge nozzle 15 and the outer side of the tabletop heating furnace 2 are provided with a heat insulation layer. The heat insulation layer is to reduce heat loss. The heat insulation layer is existing technology and will not be described in detail here.

[0025] Two polishing rods 3 are movably provided on the inner side of the tabletop heating furnace 2 for polishing the inner wall of the tabletop heating furnace 2.
