Description

Punching circle of contact head combination die

Technical field

The utility model belongs to die cutting die technical field, is specifically related to a kind of mould for the leaf end punching at leaf springs of car and circle of contact head.

Background technology

Leaf springs of car is flexible member the most traditional in automobile suspension system, due to its good reliability, simple in structure, manufacturing process flow is short, cost is low and structure such as can simplify greatly at the advantage, thereby is widely used. Leaf springs of car is generally to combine one group by some not isometric alloy spring steels to be similar to equal strength spring beam. In suspension system except rise cushioning effect and, when it is settled at automobile longitudinal, and when one end and vehicle frame fix chain connection, can shoulder transmit all respectively to force and moment, and the track of decision wheel movement, play guiding, therefore just there is no need to arrange other guiding mechanism. Leaf springs of car is that multi-disc is formed by stacking in addition, and in the time being out of shape under load, each has relative slip and produce friction, produces certain resistance, impels the vibration attenuation of vehicle body, therefore adopts this kind of structure can not fill shock absorber.

In the each reed for formed automobile leaf spring, in order to prevent and the reason such as boatswain chair interferes, its end need to be cut into circle, meanwhile, for mounting end pad and elastic head clamp, also need to be at the end of reed processing mounting holes. In existing processing method, leaf end is cut into circle and need to adopts respectively two procedures to complete at leaf end processing mounting holes, not only working (machining) efficiency is low, and multiple bearing installation can cause machining accuracy reduction, processing cost rising.

Summary of the invention

In view of this, the purpose of this utility model is to provide a kind of punching circle of contact head combination die, can be disposable in the die-cut round end of leaf end and punching, have advantages of that working (machining) efficiency is high, processing cost is low.

For achieving the above object, the utility model provides following technical scheme:

A kind of punching circle of contact head combination die, comprises upper die and lower die;

Described patrix comprises and rushes handle, and described punching is equiped with upper plate and upper padding plate upper fixed cover, and described upper padding plate is positioned at the below of described upper plate, and the described lower end that rushes handle is provided with drift; The bottom surface of described upper padding plate is provided with the cutter for die-cut round end;

Described counterdie comprises lower shoe, is installed with the die of setting corresponding to described drift and the bottom knife with the corresponding setting of described cutter on described lower shoe, is provided with the lower punching coordinating with described drift in described die;

The curved edge that the die-cut cutting edge of described cutter is indent, the curved edge that the die-cut cutting edge of described bottom knife is evagination.

Further, between described cutter and described upper padding plate, be provided with cutter baffle plate, described cutter baffle plate is fixedly mounted on described upper padding plate.

Further, described drift adopts drift locking nut to be arranged on described punching upper.

Further, between described bottom knife and described lower shoe, be provided with bottom knife backing plate.

Further, described lower punching inner sleeve is equiped with neck bush.

Further, on described lower shoe, unloading mechanism is also installed; Described unloading mechanism comprises stripper column and is arranged on the stripper on described stripper column.

The beneficial effects of the utility model are:

Punching circle of contact head combination die of the present utility model, by drift and cutter are set on patrix, die and bottom knife are set on counterdie, utilize drift and the die can punching on reed, utilize cutter and bottom knife at the die-cut round end of leaf end, so, can be disposable in the die-cut round end of leaf end and punching, have advantages of that working (machining) efficiency is high, processing cost is low.

Brief description of the drawings

In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the utility model provides following accompanying drawing to describe:

Fig. 1 is the structural representation of the utility model punching circle of contact head combination die embodiment.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As shown in Figure 1, be the structural representation of the utility model punching circle of contact head combination die embodiment. The punching circle of contact head combination die of the present embodiment, comprises upper die and lower die. The patrix of the present embodiment comprises that punching is 1, and punching is equiped with upper plate 2 and upper padding plate 3 fixed cover on 1, and upper padding plate 3 is positioned at the below of upper plate 2, and punching is provided with drift 41 lower end; The bottom surface of upper padding plate 3 is provided with the cutter 5 for die-cut round end. Between the cutter 5 of the present embodiment and upper padding plate 3, be provided with cutter baffle plate 6, cutter baffle plate 6 is fixedly mounted on upper padding plate 3. The drift 4 of the present embodiment adopts drift locking nut 7 to be arranged on punching on 1, according to processing needs, can change easily drift 4.

The counterdie of the present embodiment comprises lower shoe 8, is installed with the die 9 of setting corresponding to drift 4 and the bottom knife 10 with the corresponding setting of cutter 5 on lower shoe 8, is provided with the lower punching 11 coordinating with drift 4 in die 9.
