Abstract
The utility model discloses an upward bending structure applied to a progressive die. A downward knocking punch and a bending insert fixed on a stripper plate are arranged on the upper die of the die; a left driving rod and a right driving rod which are in sliding fit with a lower template are arranged on the lower die of the die; the bending insert is fixed at the upper end of the right driving rod; the lower ends of the left and the right driving rods are contacted with the two ends of a driving lever respectively; the driving lever is mounted on a lever fixing seat fixed on a lower die holder; and the downward knocking punch on the upper die is matched with the left driving rod which is in sliding fit with the lower template on the lower die. The upward bending structure applied to the progressive die has the benefits that the upward bending structure is compact and simple in structure, is applied to the progressive die to complete the upward bending process of a workpiece, and is flexible and accurate to operate.
Description
Technical field
The utility model belongs to machining mould, particularly a kind of upwards bending structure that is applied to progressive die.
Background technology
In progressive die, often run into and need to, to workpiece upwards bending in an operation, for different workpieces, need different upwards bending structures.
Utility model content
Technical problem to be solved in the utility model is: a kind of upwards bending structure that is applied to progressive die is provided.
The technical solution of the utility model is:
A upwards bending structure that is applied to progressive die, is characterized in that: on the patrix of mould, have downward making bar drift and be fixed on the bending mold insert on stripper; On the counterdie of mould, there are the Left Drive bar being slidably matched with lower bolster and the right drive link being slidably matched with lower bolster, in right drive link upper end, be fixed with bending mold insert, the lower end of Left Drive bar and right drive link touches the two ends of transmission levers, and transmission levers is contained on the lever holder being fixed on die shoe; Downward on patrix made the Left Drive bar that bar drift is slidably matched with lower bolster on counterdie and matched.
The utility model effect is:
This is applied to the upwards bending structure of progressive die, and delicate structure is simple, uses on progressive die, completes the upwards bending operation of workpiece.Flexible operation is accurate.
Accompanying drawing explanation
Fig. 1 is a kind of upwards mould open mode structural representation of bending structure that is applied to progressive die
Fig. 2 is a kind of upwards mould closure state structural representation of bending structure that is applied to progressive die.
In figure: the 1 dozen of bar drifts, 2 be fixed on bending mold insert, 3 on stripper be fixed on bending mold insert on right drive link, 4 and the Left Drive bar that is slidably matched of lower bolster, 5 and the lower bolster right drive link, 6 transmission levers, 7 that are slidably matched be fixed on the lever holder on die shoe.
The specific embodiment
Be applied to as shown in drawings the upwards bending structure of progressive die, upwards bending structure is applicable on progressive die, and structure comprises upper and lower die holder, upper lower bolster, discharging backing plate, fixed head, stripper, concave template and is fixed on making bar drift 1, be fixed on bending mold insert 2 on stripper on fixed head, the drive link 4 that is slidably matched with lower bolster, and the drive link 5 that is slidably matched of lower bolster, is fixed on bending mold insert 3, transmission levers 6 on drive link, is fixed on the lever holder 7 on die shoe.
Be applied to a upwards bending structure for progressive die, on the patrix of mould, have downward making bar drift and be fixed on the bending mold insert on stripper; On the counterdie of mould, there are the Left Drive bar being slidably matched with lower bolster and the right drive link being slidably matched with lower bolster, in right drive link upper end, be fixed with bending mold insert, the lower end of Left Drive bar and right drive link touches the two ends of transmission levers, and transmission levers is contained on the lever holder being fixed on die shoe; Downward on patrix made the Left Drive bar that bar drift is slidably matched with lower bolster on counterdie and matched.
The main feature of this structure is before bending mold insert 3 produces the action of upwards bending, under the effect of the spring on stripper, under the state of material strip in being killed by stripper and lower bolster, so material strip is stable when making progress bending, can arbitrarily not swing, effective and the dimensionally stable of bending, can be widely used in the progressive die of the stricter upwards bending of bending dimensional requirement.Accompanying drawing is structure diagram.
Concrete motion state is as follows:
When mould is closed, mo(u)ld top half moves down under forcing press effect, when stripper binder makes material strip contact with lower bolster, with the discharging spring that plug is fixed on upper bolster, started binder effect, along with moving downward pressure-plate-force, mo(u)ld top half increases thereupon, when making bar drift 1 and touch drive link 4, lever 6 left end decline right-hand members rise, and drive link 5 drives bending mold insert 3 to move upward, and after mould closure, completes Forging Process.After mould is opened, make bar drift 1 and depart from gradually drive link 4, at the effect underdrive bar 5 of spring, move downward, under the drive of drive link 5, each mold insert is got back to initial position.
