Description

Technical Field

[0001] This application relates to the technical field of metal smelting and casting, and in particular to a vibrating pneumatic hammer for crucible making. Background Art

[0002] A crucible is a container used to melt materials such as metals and ceramics, and it is widely used in fields such as metallurgy, chemistry, and oil refining. Among them, in the metallurgical industry, a crucible is an important tool for melting metals. Metals are placed in the crucible and heated to a high temperature to melt them. When melting metal materials through a crucible, raw materials need to be loaded into the crucible and heated by an electric frequency furnace. An electric frequency furnace concentrates the magnetic lines of force generated by an electric current on the object to be heated, and generates eddy currents by electromagnetic induction to heat the object to be heated. A furnace lining and crucible material will be filled between the crucible and the electric frequency furnace. The crucible material is generally bauxite. In order to enable the furnace lining to have a stable and long service life, the furnace lining knotting must be firm. To ensure that the furnace lining has sufficient firmness, a pneumatic furnace building machine is generally used. Currently, a pneumatic furnace building machine uses a pneumatic pusher to adjust the total length of the cylinder and the distance from the crucible. During use, the pneumatic furnace building machine uses a pneumatic hammer head to strike the inner wall of the intermediate frequency furnace crucible, and uses the vibration principle to vibrate and compact the furnace lining sand material, so that the large and small particles of the furnace lining sand material fill the voids with each other to achieve the effect of tight furnace lining sand material. The furnace building machine gradually moves up from the bottom of the crucible for 10 - 15 minutes and lifts 80 - 100 millimeters, and so on.

[0003] However, the crucible has a taper, and the diameter becomes larger towards the top. The telescopic stroke of the hammer head is limited. The existing measure taken by the furnace building machine is that during the knotting process, the cylinder - hammer combination needs to be continuously adjusted outwards through a regulator. Each adjustment requires lifting the furnace building machine from the crucible to the workbench surface, adjusting the regulator on the top surface of the furnace building machine. The regulator is provided with adjustment holes, and a shaft is inserted through the adjustment holes. According to the required telescopic length of the hammer head, the shaft is manually pulled out. After adjustment, the shaft is inserted into the adjustment hole to fix it, and then the furnace building machine is hoisted back into the crucible to continue working. Lifting it up, adjusting it, and putting it down multiple times seriously waste the working time of the furnace building machine and is inconvenient to use.

[0004] In view of the above - mentioned related technologies, there are problems of inconvenient operation and low work efficiency during the current furnace lining knotting. Utility Model Content
