Description
Technical field
The present invention relates to a kind of leaf spring processing unit (plant)s；More particularly to a kind of leaf end orthopedic systems and shaping methods.
Background technology
At this stage, leaf end shaping includes mainly two steps：
The first step rolls the leaf end after heating by short cone calender；
Second step cuts away the excess portion that leaf end is generated due to calendering by multiple-leaf spring end crop corner cut composite die
Point, keep shape regular, beautiful；
Reed raw material needed for above-mentioned shaping process are more, in second step implementation procedure, since whole process is hot-working, make
Tool wear at cropping corner cut composite die is fast, need to often replace, cost is caused to increase；And the waste material cut away can not return
It receives, causes the waste of raw material, production cost relatively high.
Invention content
In order to solve the above technical problems, it is an object of the invention to：A kind of leaf end orthopedic systems and shaping side are provided
Method is cut off without waste material, and equipment, tooling abrasion are few, save production cost.
The present invention is that technical solution used by solving its technical problem is：
The leaf end orthopedic systems, including reed squeeze head mould tool and reed racket head mold, wherein：
It includes squeezing upper die plate and crowded head lower template that the reed, which squeezes head mould tool, squeezes phase in upper die plate and crowded head lower template
To squeezing headstock and lower crowded headstock in setting, upper crowded headstock both sides, which are fixed, squeezes head briquetting, and lower crowded headstock both sides correspond to crowded head briquetting and set
Crowded grease head highness regulating part is set, and head locating piece is squeezed in the front end setting that crowded headstock under corresponding to is squeezed in head lower template, and it is right in head lower template to squeeze
The rear end of crowded headstock should be descended to be arranged and squeeze head rest sheet；
The reed racket head mold includes racket head cope plate and racket head lower template, phase on racket head cope plate and racket head lower template
Match to setting racket head block and racket head seat, inner wall shape and the leaf end shape to be processed of the racket head seat, the racket head
Reed is corresponded in lower template is additionally provided with racket head positioning component.
The crowded upper die plate and racket head cope plate of the present invention is respectively installed on hydraulic press, squeezes head lower template and racket head lower die
Plate is mounted on hydraulic press operating platform face, and according to waiting for that the specification of shaping reed is configured, when use will break for the stroke of hydraulic press
Reed after material is placed on lower crowded headstock, and carries out positioning centering to reed by squeezing head locating piece, and the reed placed is vertical
In lower crowded headstock, upper crowded headstock squeezes downwards headstock movement under the drive for squeezing upper die plate, until upper crowded headstock contact spring
Behind end, under the pressure of hydraulic press, crowded headstock interaction above and below squeezes leaf end, drives and squeeze after hydraulic press full stroke
Upper die plate returns, and completes to squeeze head.
For prevent squeeze head during hydraulic press overtravel move, cause leaf end squeeze head it is excessive, be arranged squeeze head briquetting and
It squeezes grease head highness regulating part to be limited, after hydraulic press full stroke, squeezes head briquetting and crowded grease head highness regulating part exactly in contact with, it is contemplated that
The crowded area of bed of different reeds differs, and before squeezing head, the height for squeezing grease head highness regulating part is adjusted according to the specification of head reed to be squeezed, with
Meet crowded head demand.
It squeezes the reed that head is completed to be transferred in the racket head seat of reed racket head mold, and reed is carried out by racket head positioning component
Positioning, the hydraulic press connected by racket head cope plate drive racket head block to move down, and pressure claps the leaf end after squeezing head, and leaf end is being clapped
Extend in headstock, fill up racket head seat internal pore, on the one hand racket head seat plays the role of positioning to reed, on the one hand can auxiliary reed end
Molding because racket head seat inner wall shape matches with leaf end shape to be processed, racket head complete reed no longer need to carry out
Secondary operation is done directly shaping, thus, execute the reed materials length of crowded head and racket head shaping than traditional handicraft
Small, and do not generate waste material, a frame spring can save 4-5 kilograms of raw material, and due to not having to secondary operation, save tool changing when
Between and cutter expense, the cost and production cost of raw material is greatly saved.
Wherein, preferred embodiment is：
The upper crowded headstock is identical and arranged symmetrically with the structure of lower crowded headstock, and leaf end setting is corresponded on upper crowded headstock
Upper crowded head groove, 8-15 ° of inclination angle of setting between upper crowded head groove floor and crowded upper die plate, the upper crowded long 135-160mm of head groove,
Upper crowded head recess width is adapted with reed width, and upper crowded head depth of groove 15-25mm, similarly, lower crowded headstock are equipped with lower crowded head
