Abstract
The invention relates to a production method of garden rakes, in particular to a method for integral press forming of garden rakes, which includes the following steps of selecting a 65Mn steel strip or rail plate as a raw material; integrally pressing the 65Mn steel strip or rail plate by a stamping device to form a rake plate with teeth, body and holder integrated; heating the rake plate in a heating furnace to be 1000 DEG C at least, pressing to form the teeth and the body by a pressing device through moulds, rolling to form the holder by a holder former and accordingly forming a blank rake; quenching the formed rake blank rake with the residual temperature of 550 DEG C isothermally until the HRC (Rockwell hardness) of the rake blank reaches 40-50; processing surfaces of the rake blank after quenching, and finally baking or spraying paint on the surfaces of the rake blank. By the method, the problem about connection between the body and holder of the conventional garden rake is solved, and defects of raw material waste, high energy consumption and complicated processing of the integral rake forged integrally are overcome.
Description
Technical field:
The present invention relates to the production method of gardens rake, specifically is the method for a kind of whole compacting disjunctor gardens rake.
Background technology:
Traditional gardens rake adopts the split punching press to be welded.Also because the defective that processing method is brought makes rake in use, there is the rake teeth distortion in this series products, problems such as the easy fracture of the welding at rake body and storehouse handle place except the material problem.One Chinese patent application 201110102157.1 discloses a kind of method of solid forging disjunctor bow type rake; Though solved the defective that the stamping-welded gardens of above-mentioned split rake exists; But this gardens rake forms through repeatedly heating up to forge, and still has waste raw material, the problems such as power consumption height, complex process that heat up repeatedly.
Summary of the invention:
The present invention is intended to solve the expensive problem of high energy consumption that above-mentioned gardens rake production method exists, and provide that a kind of processing method is simple, low energy consumption, the method for whole compacting disjunctor gardens rake cheaply.
The technical scheme that the present invention adopts is:
The method of a kind of whole compacting disjunctor gardens rake, carry out as follows:
A. raw material selection 65Mn is with steel or track sheet material;
B. 65Mn is used the whole punch forming rake teeth of pressing equipment, rake body and the rake trousers rake sheet as one at normal temperatures with steel or track sheet material;
C. the rake sheet is warming up to more than 1000 ℃ through heating furnace, utilizes mold to pass through press device compression moulding rake teeth and rake body, roll the rake trousers, moulding rake blank with volume trousers former;
D. the rake blank that has 550 ℃ of surplus temperature after the moulding is carried out means of isothermal quenching, make it to reach HRC40-50 hardness;
E. the rake blank after will quenching carries out surface treatment, then baking vanish or spraying.
Compared with prior art, advantage of the present invention is: adopt whole stamping, integral one-step molding and Quenching Treatment form.Aspects such as performance, toughness, hardness, elasticity, tensile strength have reached the requirement of garden instrument rake, and are not yielding in the use, more not easy fracture.Solved the connectivity problem of historic Landscapes rake body and rake trousers, also solved the solid forging disjunctor and harrowed the problem of wasting raw material, highly energy-consuming, complex process.
The specific embodiment:
Below in conjunction with embodiment the present invention is detailed.Purpose only is better to understand content of the present invention, and the example of being lifted does not limit protection scope of the present invention.
Present embodiment is the integral body compacting production method of a 13 tooth disjunctor gardens rake.Its step is following:
1. raw material selection 65Mn is with steel, and specification is wide 400mm, thick 2mm.
2. utilize pressing equipment to use the off-chip cutlery to take the method for rake tooth portion to falling, stamping out total length is the one rake sheet of 300mm, wide 240mm, the long 100mm of tooth, thick 2mm.
3. the rake sheet is got into heating furnace heat temperature raising to 1050 ℃, utilize the 3T forcing press, use molding fetal, compression moulding rake teeth and rake body, and roll the rake trousers, disposal molding rake blank with rolling up the trousers make-up machine.
4. will have the rake blank of Yu Wen about 550 ℃, and put into quenching bath and carry out Quenching Treatment, hardness is reached more than the HRC45.
5. use tumbling rolling bucket to carry out surface treatment, carry out baking vanish then.
The 13 tooth disjunctor gardens rake of producing as stated above meets the technical requirement that garden instrument is harrowed fully.
Claims (1)
1. an integral body is suppressed the method that the disjunctor gardens are harrowed, and carries out as follows:
A. raw material selection 65Mn is with steel or track sheet material;
B. 65Mn is used the whole punch forming rake teeth of pressing equipment, rake body and the rake trousers rake sheet as one at normal temperatures with steel or track sheet material;
C. the rake sheet is warming up to more than 1000 ℃ through heating furnace, utilizes mold to pass through press device compression moulding rake teeth and rake body, roll the rake trousers, moulding rake blank with volume trousers former;
D. the rake blank that has 550 ℃ of surplus temperature after the moulding is carried out means of isothermal quenching, make it to reach HRC40-50 hardness;
E. the rake blank after will quenching carries out surface treatment, then baking vanish or spraying.
