Abstract

The utility model relates to a welded ploughshare. The structure of the utility model is characterized in that the utility model is formed by the combination and the weld of a share barn, a main body of a share plate, a main body of a share point, stiffening ribs and other component parts, wherein, the share barn, the main body of a share plate and the stiffening ribs are made of plain carbon steel, and the main body of a share point is made of chisel tool steel or spring materials. Compared with the prior art, the utility model has the advantages that the share plate is not easy to break off, the sharpness of the share point is high, abrasion resistance is favorable, use cost is low, etc.

Description

A kind of welded type ploughshare

The utility model relates to a kind of ploughshare, exactly is a kind of welded type ploughshare.

Since the history, ploughshare obtains using very widely in vast rural area, and this ploughshare is a member of casting the monolithic construction that forms with White Cast Iron Material, and it mainly is made of Hua Cang, triangle ploughshare plate and the reinforcement that is positioned at above the ploughshare plate middle part.Wherein, Hua Cang is used for fixing the installation ploughshare; Ploughshare front edge of board portion is that share beak is used for guiding ploughshare to bury; The effect at other position of ploughshare plate is to be used for digging; The effect of reinforcement is a bending strength of strengthening the ploughshare plate.The major defect of this ploughshare is: 1, whole ploughshare body fragility is bigger, frangibility; 2, it is easy to wear to be positioned at the share beak position of ploughshare front edge of board, so its service life is shorter; 3, share beak is not sharp, go into ground resistance big, inefficiency; 4, use cost is higher.

The purpose of this utility model is that the ploughshare body is not fragile for people provide a kind of share beak not easy to wear, the animal-drawn plough ploughshare that use cost is lower.

The purpose of this utility model is achieved in that it comprises Hua Cang, ploughshare plate, is positioned at above the ploughshare plate reinforcement at middle part, is characterized in, the ploughshare plate is made of ploughshare plate body and share beak body two parts of being positioned at its leading section; Described Hua Cang, ploughshare plate body, reinforcement, share beak body are integrally welded.

Above-mentioned Hua Cang, ploughshare plate body, reinforcement all adopt the common straightcarbon steel material to make; Described share beak body adopts tool steel or spring steel material to make.

After realizing, the utility model compared with the prior art has following advantage: 1, because Hua Cang, ploughshare plate and reinforcement all adopt the ordinary carbon steel material to make, so the toughness of whole ploughshare body is improved, thereby frangibility, not fragile not, reduce use cost simultaneously; 2, because the share beak body adopts tool steel material to make, and handle through selective hardening, so its hardness height, anti-wear performance is good, has improved the durability and the sharp degree of share beak, also makes pears ploughshare penetration performance good simultaneously, high efficiency.

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

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

By Fig. 1, Fig. 2, as can be known, the utility model is made of ploughshare plate body 1, ploughshare storehouse 2, share beak body 4, reinforcement 3; The thickness of ploughshare plate body 1 is 5mm, and material is Q235A, and it at first makes almost plane trapezoidal shape plate through the blanking operation, makes it form arc through pressure-type process again, makes connection holes 5, positioning port 6 through the machined preface again; Ploughshare storehouse 2 be utilize thickness for 3mm, material for after Q235A sheet material makes the rectangle plate, make it become channel member through pressure-type process again; It is that 8mm, material are the round steel of No. 35 steel that reinforcement adopts diameter, makes by the design length blanking; It is the T of 7mm that the share beak body adopts thickness, and 10 tool steel materials are pressed the figure forging molding, and process cutting edge.After above-mentioned ploughshare plate body, Hua Cang, reinforcement, share beak body are got all the ready, be welded into one by figure; After the welding moulding, to go into the body direction be short transverse and heat, heat warm multitudinous 800-850 ℃ from the paracone end points of share beak body in width is the scope of 10mm, be 10-15 second heat time heating time, quenches with aqueous medium afterwards, and the cool time is 5-10 second; Use oily medium quenching again, the cool time is 15-20 second, cooling naturally afterwards, and making it in the thermal treatment zone to form hardness is the quenched zone of HRC55-50, and makes share beak dual-side hardness reach HRC35-30 to get final product.

Above-mentioned share beak body part also can be made each one of profile with the machine adding method; Its material also can be selected T8 tool steel or spring steel for use.

The material of above-mentioned ploughshare plate body, Hua Cang also can be selected Fine Steel Casting iron for use, as No. 35 steel etc., can also select weldability low-carbon alloy steel preferably for use, as 16Mn etc.; The material of reinforcement can also be selected common straightcarbon steel or low-carbon alloy steel for use; This reinforcement can also be made with corresponding thick steel plate.

The ploughshare that provides among the figure is a kind ofly can be used for mechanical plough, can be used for the ploughshare of animal-drawn plough again.When it was used as the animal power ploughshare, its method of manufacturing technology was identical with the content of embodiment, and when it was used as mechanical ploughshare, its ploughshare plate body, share beak body, Hua Cang were respectively formed the sheet metal thickness of member and answered corresponding increase, and the sectional dimension of its reinforcement should corresponding increasing.Certainly, the utility model is equally applicable to other animal power ploughshare.

Claims

1, a kind of welded type ploughshare comprises Hua Cang, ploughshare plate, is positioned at above the ploughshare plate reinforcement at middle part, it is characterized in that the ploughshare plate is made of ploughshare plate body and share beak body two parts of being positioned at its front end; Described Hua Cang, ploughshare plate body, reinforcement, share beak body are integrally welded.

2, a kind of welded type ploughshare according to claim 1 is characterized in that described Hua Cang, ploughshare plate body, reinforcement all adopt the common straightcarbon steel material to make; Described share beak body adopts tool steel or spring steel material to make.
