Abstract

The utility model relates to a universal standard template for the quenching of a steel plate spring. The universal standard template for the quenching of the steel plate spring comprises 25 arched steel plates with the chord lengths of 1,200 to 1,300mm, wherein the radiuses of inner arcs of the 25 arched steel plates are 600mm, 660mm, 750mm, 900mm, 1,050mm, 1,150mm, 1,270mm, 1,400mm, 1,550mm, 1,700mm, 1,870mm, 2,050mm, 2,250mm, 2,450mm, 2,650mm, 2,900mm, 3,100mm, 3,380mm, 3,700mm, 4,000mm, 4,400mm, 4,800mm, 5,200mm, 5,700mm and 6,200mm respectively; the radius of an outer arc of each arched steel plate is 15mm more than the radius of the inner arc; and the center of circle of the inner arc of each arched steel plate is at a distance of 35mm away from the center of circle of the outer arc. More than 8,000 kinds of conventional quenching templates are reduced to 25 standard templates forming a set, so that the number of arranged templates is greatly decreased, manpower, material resources and financial resources consumed by the manufacture of the templates are saved, the templates can be conveniently stored and managed, and cost in the manufacture, management, maintenance and the like of the templates is greatly decreased.

Description

Leaf spring quenching universal standard model

Technical field

The utility model relates to a kind of spring thermal treatment apparatus, specifically a kind of leaf spring quenching universal standard model.

Background technology

In process of production, the quenching of leaf spring all will be used model, and the making of model generally all is that the system of striking forms by hand.Leaf spring generally is divided into two big types of uniform cross section and variable cross sections, and every kind of leaf spring product in one type of the uniform cross section all wants corresponding one to overlap the quenching model, therefore, cover whole leaf springs, just needs 8000 multi-disc models.So the sample making of each leaf spring manufacturing enterprise all is a very hard work with management.A model storehouse will be set usually, and the iron plate of various vehicles has been piled and to the clip model in the inside, and in use can't mix up, otherwise can cause more serious adverse consequences.

The utility model content

The purpose of the utility model just provides a kind of leaf spring general model that quenches, and significantly to reduce model quantity, is convenient to leaf spring manufacturing enterprise depositing, using and managing model.

The utility model is achieved in that leaf spring quenching universal standard model comprises that 25 chord lengths are the curved plate of 1200-1300 millimeter, and the inner arc radius of said 25 curved plates is respectively: 600mm, 660mm, 750mm, 900mm, 1050mm, 1150mm, 1270mm, 1400mm, 1550mm, 1700mm, 1870mm, 2050mm, 2250mm, 2450mm, 2650mm, 2900mm, 3100mm, 3380mm, 3700mm, 4000mm, 4400mm, 4800mm, 5200mm, 5700mm, 6200mm; The outer arc radius of each curved plate is that said inner arc radius adds 15 millimeters; The inner arc center of circle of said each curved plate and the outer arc center of circle are at a distance of 35 millimeters.

On each model, be provided with the mark of scribing that comprises numbering and standard curvature, be convenient to deposit, manage and select for use.

The utility model is through carrying out statistical study to information such as the length of uniform cross section leaf spring, height; Curvature to leaf spring is classified; And produce 25 standard jigs at interval, thereby realized that a standard jig is suitable for the quenching of curvature a plurality of uniform cross section leaf springs within the specific limits by certain curvature.During quenching, the uniform cross section leaf spring of curvature at interval with the immediate standard jig of radius-of-curvature as the quenching model, leaf spring is carried out Quenching Treatment.

The quenching model that the utility model will have kind more than 8000 now is reduced to 25 one standard jigs that overlap; The quantity that is provided with of model greatly reduces; Like this; Both saved spent human and material resources and the financial resources of sample making, made things convenient for depositing, use and managing of model again, greatly reduce model making, general expenses such as administer and maintain.

The utility model important a bit, the iron plate model that is that it goes without doing and to the clip model, the leaf spring of all models is only used 25 standard jigs, ten minutes helps the exploitation of management by example and new model like this, has saved the man power and material.

Facts have proved that through production practice over one year this is that an effective model is confirmed method.Originally develop new varieties, two model workers begin from cooing the iron plate model, to pounding the clip model, need two to three days at least; After using this standard jig, these work have all been saved, and all vehicles only use this 25 standard jigs, have also saved check and correction and maintenance.

Description of drawings

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

Embodiment

As shown in Figure 1; Use the steel plate of 25 length as 1200-1300mm; By following moulding standard, make a cover standard jig: the inner arc radius R 1 of said 25 curved plates is respectively: 600mm, 660mm, 750mm, 900mm, 1050mm, 1150mm, 1270mm, 1400mm, 1550mm, 1700mm, 1870mm, 2050mm, 2250mm, 2450mm, 2650mm, 2900mm, 3100mm, 3380mm, 3700mm, 4000mm, 4400mm, 4800mm, 5200mm, 5700mm, 6200mm; The outer arc radius R 2 of each curved plate adds 15 millimeters for said inner arc radius R 1; The inner arc center of circle and the distance h between the outer arc center of circle of said each curved plate are 35 millimeters.

On each model, cut out the mark that comprises numbering and standard curvature etc., so that search.
