Abstract

The utility model belongs to a mechanical cutting technical field, relating to a calcium carbide round hole drilling machine on a barrel, being used for drilling round holes with different diameters on thin-wall metal column barrels. The utility model uses a radial drilling machine as power, and the calcium carbide round hole drilling machine on barrel is provided with a rolling blade which drills the round holes on the planes of the thin-wall metal column barrels. The utility model has simple process and structure, easy operation, no deformation to the barrels and high producing efficiency, and the drilled round holes have smoothness and good qualities.

Description

The calcium carbide barrel notching device

The utility model belongs to the machine cuts technical field, cuts the calcium carbide barrel notching device of the different circular hole of system diameter on particularly a kind of thin-wall metal cylinder barrel that is used to seal.

At present, in the calcium carbide of chemical enterprise is produced, relate to the packing that a large amount of thin-wall metal buckets is used for the calcium carbide product.Can make on the one hand that new bucket is packed but cost is higher.Available on the other hand old oil drum, old industrial chemicals packing with bucket, and other old bucket change a social system, the cost reduction, economical and practical.In the new bucket making and the old bucket transformation of the way, all exist new opening and the less need of the old former opening of bucket to increase big mouthful of conduct charging and material taking mouth.In new system and restructuring process, mostly adopt gas cutting and manual the engraving tool to cut.Like this, make a bucket distortion and the rough rounding of otch easily, make fixingly during at next process, cause difficulty, both influence transformation of the way speed and also influence transformation of the way quality with seal cover.

The utility model for solving the defective of above-mentioned existing transformation of the way technology, and provides a kind of new technical scheme of opening the cyclotomy hole with the scroll-diced cutter on the thin-walled drum.

The technical solution of the utility model is, is equiped with adjustable plate 2 on the drill bit taper hole fixed handle of radial drilling machine 1, and adjustable plate 2 connects by bolt and knife rest 3, and blade 4 is connected on the knife rest 3 by pivot pin 5, realizes cutting opening when blade 4 rolls on calcium carbide barrel 6.

The utility model utilizes the blade 4 of pipe cutter to change the tangent line circumference and is cut into the planar circumferential cutting, the diameter of cutting circular hole can be adjusted by adjustable plate 2; the drill bit fixed handle of radial drilling machine 1, scope of activities is big, the diameter of adjustable joint calcium carbide barrel and incision site.The circular hole edge of this device cutting is smooth, bucket is indeformable, cutting speed fast, improve transformation of the way efficient and quality.

Accompanying drawing 1 and Fig. 2 are mounting structure figure of the present utility model, and Fig. 1 is the front view of present embodiment, and Fig. 2 is that the A of Fig. 1 is to view.The utility model will be further described below in conjunction with accompanying drawing.

Radial drilling machine 1 of the present utility model is the national standard approved product, on its drill bit fixed handle, be equiped with adjustable plate 2, should weld the taper shank that matches with rocking arm drill bit fixed handle taper hole on the adjustable plate 2, its adjustable plate 2 can be fastened on the power transmission shaft (drill bit fixed handle) of radial drilling machine.Adjustable plate 2 usefulness steel material are made, and are provided with regulating tank on adjustable plate 2, and the making of knife rest 3 usefulness steel material is passed regulating tank with bolt and is fixed on the adjustable plate 2.Blade 4 is connected on the knife rest 3 by pivot pin 5 with blade on the pipe cutter.Operation principle: make circumference by power transmission shaft (drill bit fixed handle) the drive adjustable plate 2 of radial drilling machine 1 and rotate.Adjustable plate drives knife rest 3 and rotates, and blade 4 is promptly made planar circumferential at the calcium carbide barrel end face and rolled, thereby reaches the purpose of cutting circular hole.The big I of Circularhole diameter is regulated the distance at blade cutting edge center to circular hole center by the regulating tank on the adjustable plate 2.

The utility model process structure is simple, operation is simple and easy, cutting speed fast, the calcium carbide barrel quality of the transformation of the way is good.

Claims

1, calcium carbide barrel notching device is characterized in that being equiped with adjustable plate (2) on the drill bit taper hole fixed handle of radial drilling machine (1), is equiped with knife rest (3) on the adjustable plate (2), knife rest (3) is gone up with pivot pin (5) and connected blade (4).

2, according to the said calcium carbide barrel notching device of claim 1, it is characterized in that adjustable plate (2) is provided with regulating tank, be used to adjust the diameter of cutting circular hole.
