Abstract
Disclosed is a pick drilling rod for a pneumatic pick. The pick drilling rod connected with the pneumatic pick comprises a pick drilling rod body, a pick drilling rod end and a pick drilling rod head, wherein a boss is arranged between the pick drilling rod end and the pick drilling rod body. The pick drilling rod for the pneumatic pick is characterized in that a welding hole is axially arranged on the pick drilling rod head, tungsten steel which is cemented carbide is embedded in the welding hole. The pick drilling rod is made of number 45 steel, as the best cemented carbide, the tungsten steel has a strong abrasion resistance in breaking hard objects of ores and the like, the tungsten steel embedded in the pick drilling rod head can be continuously used for more than 20 hours and the repair rate is low so that a worker can carry one pick drilling rod to work for a whole day. Compared with the existing pick drilling rod which can only be used for 2-4 hours, and has to be stricken, forged and quenched again when abraded, the pick drilling rod can save replacing time in working so that the working efficiency is guaranteed, when the top of the pick drilling rod head is abraded, the top is only polished by a abrasion wheel and then can be continuously used, and the maintenance is convenient, according to the pick drilling rod, the steel consumption and the cost of materials are remarkable reduced.
Description
Technical field
The utility model relates to gas pick, particularly relates to a kind of pick rod of gas pick, is mainly used in the fragmentation of ore, rigid pavement, building, colliery, construction of tunnel and rock secondary.
Background technology
Gas pick is also referred to as pneumatic pick; Employing compressed air is power; Being installed in pick rod in the gas pick to ore, rigid pavement, building, colliery or construction of tunnel, and hard objects such as rock carries out fragmentation, because gas pick is easy to use; Be applicable to artificial move operation, particularly the most frequently used in road and demolishing buildings.Pick rod is a consumable accessory, uses processing such as waiting the steel process forges, quenching for No. 45 made, and is different according to the hardness of broken object; After can only using 2-4 hour under the continuous uninterrupted work, the pick rod tip just is worn, and needs to forge again and could use; Therefore, the pick rod of existing gas pick exists easy to wear, is not durable; Repair rate is very high, forges again, Quenching Treatment is pretty troublesome at every turn, and the worker need carry many pick rods on every day; Change and lose time again, influence operating efficiency, particularly consumed a large amount of steel because of pick rod.Thus, the someone has invented shock-resistant, wear-resisting pneumatic pick pricker is as Chinese patent ZL200920035423.1 number; The technical scheme of this patent is in the whole pick rod outside of No. 45 steel wearable hard alloy to be arranged, and has improved anti-wear performance, has prolonged service time; But the wearing and tearing of pick rod are particularly top at head, and the carbide alloy of this pick rod head in a single day wearing and tearing back integral body is scrapped; Shortcomings such as it is big to exist the carbide alloy consumption, and the user can not repair use, and waste of material is big.
Summary of the invention
The purpose of the utility model is to repair man-hour, the pick rod of a kind of gas pick of high efficiency in order to overcome the shortcoming that prior art exists, to provide a kind of head anti-wear performance of pick rod good, can repeatedly repair use, practice thrift great deal of steel, saving.
The technical scheme of the pick rod of a kind of gas pick of the utility model is: the pick rod that is connected with gas pick comprises pricker body, bit shank and bore bit; Between bit shank and pricker body, be shaped on boss; It is characterized in that described bore bit axially is shaped on welding hole, tungsten carbide button-wolfram steel in the welding hole.
The utility model discloses a kind of pick rod of gas pick, pick rod is made by No. 45 steel, and the afterbody of pick rod is connected with gas pick; Wolfram steel is best carbide alloy, and anti-wear performance is strong during to the fragmentation of hard objects such as ore, is embedded in and can uses more than 20 hour in the bore bit continuously; Repair rate is low, as long as just on every day man-hour carry one and can use one day, can only use 2-4 hour with respect to existing pick rod; Again forge again after the wearing and tearing, Quenching Treatment, the time of changing pick rod has been saved the time in the work of this pick rod, has guaranteed operating efficiency; After the top wearing and tearing of pick rod head, as long as, keep in repair very convenient with continuing use under the emery wheel reconditioning again; This pick rod has reduced the consumption of steel greatly, has reduced the cost of material significantly.The pick rod technology that this programme is inlayed wolfram steel at bore bit also can be used in the hexagonal chisel of electric hammer, and electric hammer is to be used for the instrument that body of wall is driven wiring duct or rooted out glazed wall tile etc.
The pick rod of a kind of gas pick of the utility model, described welding hole and wolfram steel are connect by brazing and form braze layer.Adopt copper liquid that wolfram steel and bore bit are welded, rapid operation, fastness is good.Described wolfram steel length L is 10-40mm, and diameter of phi is 3-14mm.Wolfram steel is long, and the available emery wheel sharpening in wearing and tearing back re-uses, longer service life, and generally about 24mm, the diameter of phi of inlaying wolfram steel is 3-14mm to the external diameter of pricker body, the wolfram steel diameter is thick, and is durable in use, but will keep the certain thickness of No. 45 steel of pick rod.

Fig. 2 is the structural representation of the pick rod of a kind of gas pick of the utility model;
Fig. 3 is the structural representation of electric hammer with the hexagonal chisel.
The specific embodiment
The utility model relates to a kind of pick rod of gas pick; Like Fig. 1-shown in Figure 3, the pick rod that is connected with gas pick 1 comprises pricker body 3, bit shank 5 and bore bit 2, is shaped on boss 4 at bit shank 5 and 3 of pricker bodies; It is characterized in that described bore bit 2 axially is shaped on welding hole 21, tungsten carbide button-wolfram steel 22 in the welding hole.Pick rod is made by No. 45 steel, and the afterbody of pick rod is connected with gas pick, and wolfram steel is best carbide alloy; Anti-wear performance is strong during to the fragmentation of hard objects such as ore, is embedded in and can uses more than 20 hour in the bore bit 2 continuously, and repair rate is low; As long as carry one just can use one day man-hour on every day, can only use 2-4 hour with respect to existing pick rod, forge again again after the wearing and tearing, Quenching Treatment; Save the time of changing pick rod during the work of this pick rod, guaranteed operating efficiency, after the top wearing and tearing of pick rod head; As long as with continuing use under the emery wheel reconditioning again; Keep in repair very conveniently, this pick rod has reduced the consumption of steel greatly, has reduced the cost of material significantly.The pick rod technology that this programme is inlayed wolfram steel 22 at bore bit 2 also can be used in the hexagonal chisel 7 of electric hammer, and electric hammer is to be used for the instrument that body of wall is driven wiring duct or rooted out glazed wall tile etc.Described welding hole 21 is connect by brazing with wolfram steel 22 and forms braze layer 23.Adopt copper liquid that wolfram steel 22 and bore bit 2 are welded, rapid operation, fastness is good.Described wolfram steel 22 length L are 10-40mm, and diameter of phi is 3-14mm.Wolfram steel 22 is long, and the available emery wheel sharpening in wearing and tearing back re-uses, longer service life, and generally about 24mm, the diameter of phi of inlaying wolfram steel 22 is 3-14mm to the external diameter of pricker body 3, wolfram steel 22 diameters are thick, and are durable in use, but will keep the certain thickness of No. 45 steel of pick rod.
