Abstract

The utility model relates to a welding slag knocking hammer which is characterized in that the hammer comprises a hammer body (1), wherein, the front end of the hammer body is provided with a hollow pipe. An elastic body (2) with buffer action is arranged at the bottom in the pipe; the front end abutting on the elastic body (2) in the pipe is provided with a sharp chisel-shaped hammer head (3) which abuts on the pipe wall in the pipe and is capable of moving from front to rear. The utility model can automatically adjust force on a knocking workpiece to have coincident size; the surface of the workpiece is not knocked into deep pits. The hammer head is not easy to bounce and crack.

Description

Welding slag knocking hammer

The utility model relates to the hammer that knocks the electroslag welding that stays on the workpiece after the electric welding.

At present, the hammer that knocks the electroslag welding that stays on the workpiece after the electric welding is common hammer, and hammer divides handle and hammer two parts to form, and hammer promptly is one whole that is fabricated from iron, and the centre has a hole can pass handle.Remove to strike electroslag welding with this hammer, because people's hand-power is difficult to accomplish that each down evenly, therefore heavy once, once gently be, because the hand-power inequality often is directed at surface of the work and forms dark pit through common occurrence, and also often be directed at the working face of hammer or collapse or split, or easily hitting bluntly, this will grind again, quench behind the mill again, and quenching hardness is restive again, brings inconvenience to use.

The purpose of this utility model provides a kind of when surface of the work strikes electroslag welding, and hammer can be by self to the adjustment of dynamics, and it is each large and small almost to realize that hammer knocks in the power of surface of the work, and is difficult for collapsing and is difficult for splitting, and is not easy to wear.

Technical solution of the present utility model is on the basis of the handle of existing hammer, a hammer body is arranged, hammer front end at hammer body is the pipe of hollow, elastomer as cushioning effect is arranged at the bottom in pipe, the elastomeric front end that is right after in pipe has a point to chew the tup of cutter shape, and the tup of cutter shape is right after tube wall and can moves forward and backward in pipe.

Operation principle of the present utility model is owing between tup and the hammer body elastomer is arranged, and tup can move forward and backward in the pipe of the hollow of hammer body front end.Like this at hammer when firmly knocking the electroslag welding of surface of the work, as firmly excessive, the tup power of compression elasticity body backward is also big, because elastomer produces bigger cushioning effect to the excessive power that tup knocks surface of the work.And exert oneself when too small the people, the tup power of compression elasticity body backward is also little, thereby also little to the buffering dynamics of its generation.Because elastomer is adjusted the dynamics that tup acts on surface of the work, make it large and small different power by can be similar substantially after adjusting, though long-term use the back because of collapse, split, blunt, cause tup to be scrapped, also only need it is extracted, change a new tup and just can use as usual.

The utility model has the advantages that when striking the surface of the work electroslag welding with hammer, by hammering self adjustment into shape to dynamics, make it to act on the large and small basically identical of power of surface of the work at every turn, thereby guaranteed that surface of the work can not hit into dark pit, tup is difficult for collapsing, is difficult for splitting, is difficult for hitting blunt, and tup can also be changed.And simple structure, be easy to processing, with low cost, long service life, not only can knock electroslag welding usefulness, and also can make common hammer usefulness, practical, be easy to promote.

Below in conjunction with accompanying drawing the utility model embodiment is described:

Fig. 1 is an organigram of the present utility model.

According to shown in Figure 1, the utility model has a handle (4), a hammer body (1) is arranged, be the pipe of hollow at the hammer front end of hammer body (1), rubber blanket (2) as cushioning effect is arranged at the bottom in pipe, the front end that is right after rubber blanket (2) in pipe has a tup (3) like the diamond bit shape, and the tup (3) of cutter shape is right after tube wall and can moves forward and backward.

The hollow cavity of the pipe of above-described hammer body (1) front end can be cubic bar shape, also can be cylindrical shape.

Rubber blanket of the present utility model (2) can be cubic bar shape, also can be cylindrical shape.

The above rubber blanket (2) can be a central through hole.

The peripheral shape at the rear portion of tup of the present utility model (3) and hammer body (1) inner chamber adapt, and the front end of tup (3) can be the head of alloy.
