Description

Plate reed rolling bending die

Technical Field

The utility model relates to a mould field, concretely relates to leaf spring roll-in bender.

Background

At present, when a plate spring piece is bent and shaped, the plate spring piece is directly pressed by an upper die and a lower die of a bending die to form a bent angle. Because the plate reed is formed by hot working, the upper die of the bending die directly contacts the plate reed in the bending forming process, the surface of the plate reed is damaged due to high relative speed and high abrasion tendency, and the surface damage in the bending process is difficult to recover, so that the product quality is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a not enough to prior art, provide the structure one kind simply, convenient operation's leaf spring piece roll-in bender.

In order to achieve the above purpose, the utility model discloses a technical scheme is: the utility model provides a leaf spring roll bending die which characterized in that includes: the upper die comprises an upper die plate, a die shank, an upper die base, a rolling shaft and a center pin, the upper die plate is fixedly connected with the upper die base, the die shank is sleeved on the upper die plate and is fixedly connected with the upper die base, and the rolling shaft is connected with the upper die base through the center pin; the lower die comprises a lower die plate, a lower die base support, a bracket, a positioning pin and a positioning plate, the bracket is fixedly connected to the lower die plate, the positioning pin and the positioning plate are respectively connected to the long arm end of the bracket through bolts, the lower die base is connected to the lower die base support through bolts, and the lower die base support is fixedly connected to the lower die plate.

The utility model discloses simple structure, convenient operation can improve the appearance quality of work piece, ensures the high-quality production of board reed.

Drawings

Fig. 1 is a schematic structural view of a plate spring sheet rolling bender of the present invention.

Fig. 2 is a side view of the upper die of the present invention.

Wherein the figures are labeled: 1. the die comprises an upper die 1-1, an upper die plate 1-2, a die handle 1-3, an upper die base 1-4, a rolling shaft 1-5, a center pin 2, a lower die 2-1, a lower die plate 2-2, a lower die base 2-3, a lower die base support 2-4, a bracket 2-5, a positioning pin and a positioning plate 2-6.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

referring to the attached drawings 1-2, the utility model provides a leaf spring roll-in bender, include: the die comprises an upper die (1) and a lower die (2), wherein the upper die (1) comprises an upper die plate (1-1), a die handle (1-2), an upper die base (1-3), a rolling shaft (1-4) and a center pin (1-5), the upper die plate (1-1) is fixedly connected with the upper die base (1-3), the die handle (1-2) is sleeved on the upper die plate (1-1) and fixedly connected with the upper die base (1-2), and the rolling shaft (1-4) is connected with the upper die base (1-3) through the center pin (1-5); the lower die (2) comprises a lower die plate (2-1), a lower die base (2-2), a lower die base support (2-3), a bracket (2-4), a positioning pin (2-5) and a positioning plate (2-6), the bracket (2-4) is fixedly connected to the lower die plate (2-1), the positioning pin (2-5) and the positioning plate (2-6) are respectively connected to the long arm end of the bracket (2-4) through bolts, the lower die base (2-2) is connected with the lower die base support (2-3) through bolts, and the lower die base support (2-3) is fixedly connected to the lower die plate (2-1).

In the embodiment, when the plate spring leaf (3) is ready for the angle bending operation, the gap between the upper die (1) and the lower die (2) is adjusted, the plate spring leaf (3) is placed on the bracket (2-4), the positioning pins (2-5) and the positioning plates (2-6) are used for double positioning, then the upper die (1) is pressed down, the roller (1-4) is firstly contacted with the plate spring leaf (3), and the roller (1-4) rolls around the center pin (1-5) to be contacted with the surface of the plate spring leaf (3), so that the friction force is greatly reduced, and the appearance quality of the plate spring leaf (3) is ensured. After the upper die (1) and the lower die (2) are pressed, the integral bending angle shaping of the plate spring leaf (3) is completed, then the upper die (1) is lifted, the processed plate spring leaf (3) is taken out, and the bending angle lug process of the plate spring leaf (3) is completed.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
