Abstract

The utility model relates to a hammer, which includes a steel bonded carbide hammer cap and a carbon steel hammer cast and welded to the upper part of the hammer cap, wherein a plurality of blind holes are arranged in the hammer cap, and a plurality of corresponding bulges are arranged at the bottom end of the hammer. The utility model has the characteristics that the ordinary carbon steel brings the excellent weldability with the connecting rod into full play, and the cost is low, the high-temperature, corrosion and abrasion resistance of the hammer cap ensures the long-term effective functioning of the hammer; at the same time, as the punching process of the hammer cap is rather simple, the casting connection and welding double ensure the fixed connection between the hammer cap and the hammer, and the service life of the hammer is prolonged at last.

Description

A kind of tup

Technical field

The utility model relates to a kind of tup, relates in particular to a kind of long lifetime tup with the hammer cap.

Background technology

Metal plays a part very important in world's expanding economy, and the process that the preparation of a lot of metallic substance need be passed through smelting is the unique channel that obtains industrial aluminum such as the aluminum current electrolysis.Tup is one of important tool of carrying out in the Metal smelting raw material interpolation, and the Metal smelting pond has the characteristics of high temperature, deep-etching, strong wearing and tearing, very easily brings the tup loss of under this condition, working.

With the electrolysis of aluminum is example, and at present be to solve a tup spending rate fast difficult problem less than three months tup work-ing life of a large amount of general carbon steel materials that adopt, and relevant both at home and abroad aluminum smelting technology enterprise has carried out lot of test and research work, has obtained certain progress.Use high temperature steel ZG30Cr26Ni5, ZG30Cr20Nil0 to process like patent " crust beating hammer for aluminium electrolysis " (200610050934.1); When keeping the high-chromium amount; The nickel that also contains 5%-10%, though the wear resistance and corrosion resistance of tup is improved, its material cost is high; And high-load chromium and nickel make tup and air cylinder connecting rod be difficult to welding, and weld metal is prone to produce HOT CRACK FOR WELDING P.

The utility model content

The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of tup of high temperature resistant, wear-resistant, corrosion-resistant, long service life that cost performance is high is provided.

The technical scheme that the utility model adopts:

A kind of tup, it comprises Steel Bond Hard Alloy hammer cap and casting and is welded on the carbon steel tup on hammer cap top, hammers cap into shape and is provided with a plurality of blind holes, the tup bottom is corresponding to be provided with a plurality of convexities.

Above-mentioned blind hole has the inclination angle of 70-80 degree.

Above-mentioned blind hole depth is 20mm.

Above-mentioned hammer hat brim edge is provided with the outer, and the hammer cap is the matrix hypocrateriform.

The technique effect that the utility model is obtained:

1, the utility model tup adopts powder metallurgy method to make the hammer cap, adopts the method for casting will hammer cap into shape and is fixedly connected with tup, and blind hole with angle makes hammers the cap difficult drop-off into shape; And adopt the method for welding to reinforce the connection; Be characterized in that general carbon steel brought into play the good welds property of itself and connecting rod, cheap, high temperature resistant, corrosion-resistant, the anti abrasive performance of hammer cap has guaranteed effectively its effect of performance of tup longer time; Simultaneously; The Sheet Metal Forming Technology of hammer cap is comparatively simple, and casting connects and welds dual being fixedly connected of hammer cap and tup that guaranteed, finally prolongs the work-ing life of tup.

Description of drawings

Fig. 1 is the front view of the utility model;

Fig. 2 is the vertical view of tup in the utility model.

Wherein: 1 is tup, and 2 are the hammer cap, and 3 is the outer, and 4 is blind hole, and 5 is protruding.

Embodiment

Below in conjunction with accompanying drawing the embodiment of the utility model is done further explanation.

Referring to Fig. 1-2, a kind of tup, it comprises Steel Bond Hard Alloy hammer cap 2 and the carbon steel tup 1 of casting and be welded on hammer cap top, and the hammer cap is provided with a plurality of blind holes 4, and the tup bottom is corresponding to be provided with a plurality of protruding 5.Described blind hole has the inclination angle of 70-80 degree.Described blind hole depth is 20mm.Described hammer hat brim edge is provided with outer 3, and the hammer cap is the matrix hypocrateriform.

The working method of the utility model:

1, make cylindrical steel bond hard alloy piece according to the tup size, bottom surface circular diameter identical with tup matrix diameter (common is about φ 100mm) highly is 20 ~ 50mm;

2, the method with punching press manufactures the Steel Bond Hard Alloy piece matrix hypocrateriform that contains hammer cap outer 3;

3, produce four blind holes, the inclination angle in hole is 70 ~ 80 degree, is example with the tup of diameter phi 100mm, and the top dimension in hole is about φ 16mm, and bottom size is about φ 20mm, and hole depth is about 10mm;

4, on hammer cap basis, adopt castmethod to produce carbon steel tup 1;

5, adopt austenite stainless steel-made welding rod that tup and hammer cap are reinforced the connection.

The protection domain of the utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from the scope and the spirit of the utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the intention of the utility model also comprises these changes and is out of shape interior.
