Description

Technical Field

[0001] The utility model relates to the technical field of graphite electrodes, in particular to a dust cover for a graphite electrode boring machine tool. Background Art

[0002] Graphite electrodes are mainly made of rock tar and needle tar as raw materials, and coal tar as a binder. They are made through calcination, batching, kneading, pressing, roasting, graphitization and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the charge. According to their quality indicators, they can be divided into ordinary power, high power and ultra-high power.

[0003] At present, when processing holes in graphite electrodes, boring is used for processing. However, when processing deeper electrode holes, the tool needs to be extended long enough to complete the process. Therefore, when the tool is extended long, the powder generated during boring is easy to fall on the outside of the dust cover, which needs to be cleaned in time, increasing the workload. This is a shortcoming of the existing technology. Utility Model Content

[0004] The purpose of the utility model is to solve the problems raised in the above background technology, and then propose a technical solution of a dust cover for a graphite electrode boring machine tool.

[0005] The utility model solves the technical problem by adopting the following technical solution: a graphite electrode boring machine dust cover, comprising a dust cover body, one end of which is fixed with an extended dust cover, and a tool of the boring machine is located in the extended dust cover.

[0006] A further improvement of the utility model is that a conical transition plate is provided between the extended dust cover and the dust cover body, one end of the conical transition plate is fixedly connected to the dust cover body, and the other end of the conical transition plate is provided with a plurality of notches.

[0007] A further improvement of the utility model is that a locking mechanism is arranged between the extended dust cover and the dust cover body, and the locking mechanism includes a first sliding sleeve, a second sliding sleeve, an insertion rod and a locking bolt, the first sliding sleeve is fixed to the extended dust cover, the second sliding sleeve is fixed to the dust cover body, and the insertion rod is arranged in the first sliding sleeve and the second sliding sleeve; a bolt hole is arranged on the first sliding sleeve, and a locking bolt for locking the insertion rod is installed in the bolt hole.

[0008] A further improvement of the utility model is that the first sliding sleeve is connected to the extended dust cover via a bracket.

[0009] A further improvement of the utility model is that the second sliding sleeve is welded and fixed on the mounting plate, and the mounting plate is fixed to the dust cover body by screws.

[0010] A further improvement of the utility model is that the locking mechanism has two sets, which are respectively arranged on the front and rear sides of the extended dust cover.

[0011] The beneficial effect of the utility model is that the utility model adds an extended dust cover. Since the tool is located in the extended dust cover, when the tool needs to process a deep electrode hole, it can effectively reduce dust powder falling to the outside of the dust cover, thereby reducing the frequency and difficulty of cleaning, and has a strong application and promotion value.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. The utility model is further described in combination with the drawings and embodiments:

[0017] like Figure 1-3 As shown, a graphite electrode boring machine dust cover comprises a dust cover body 2, an extended dust cover 4 is fixed to one end of the dust cover body 2, and a tool 7 of the boring machine is located in the extended dust cover 4. The utility model installs the extended dust cover 4 at one end of the original dust cover body 2, so that the tool 7 is located in the extended dust cover 4. When the tool 7 needs to process a deep electrode hole, it can well reduce dust powder falling to the outside of the dust cover, thereby reducing the frequency and difficulty of cleaning.

[0018] Furthermore, in order to reduce the debris and dust falling from between the extended dust cover 4 and the dust cover body 2 during boring, the utility model provides a conical transition plate 3 between the extended dust cover 4 and the dust cover body 2, one end of the conical transition plate 3 is fixedly connected to the dust cover body 2, and the other end of the conical transition plate 3 is provided with a plurality of notches. The purpose of providing the notches is to facilitate the installation and removal of the extended dust cover 4.
