Abstract

The utility model discloses a smooth surface leveling die, which relates to a die and comprises an upper die holder, a lower die holder and a die shank. The die shank is arranged in the upper die holder, a leveling convex die is arranged on the lower surface of the upper die holder, the die shank is a floating die shank and matches with the leveling convex die via an upper spherical joint, a leveling table board is arranged on the lower die holder, is connected with the lower die holder via a resetting screw and matches with the lower die holder via a lower spherical joint, and a resetting spring is sleeved on the resetting screw. Preferably, the upper die holder and the lower die holder are made of Q235 steel, and the leveling convex die is made of CrWMn steel. The smooth surface leveling die can reduce influence to leveling due to errors of parallelism of a table board of a press machine and the lower plane of a slider, is high in precision of products and fine in quality of the products, and is quite practical.

Description

A kind of light face straight die

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of light face straight die.

Background technology

In punching production, for improve workpiece surface quality and precision, usually need the workpiece behind stamping-out or the blanking is smoothed processing, soon the surface of the workpiece behind stamping-out or the blanking flattens again straight, for the thin and surperficial workpiece that does not allow impression, generally be to adopt light face straight die to smooth.When using existing light face straight die to smooth, the influence of the error of the table top of the machine that is stressed and the slide block lower plane depth of parallelism, its smoothing effect is undesirable, and the product precision is low.

Summary of the invention

At the problem that above-mentioned prior art exists, the utility model provides a kind of light face straight die, table top that can reduce forcing press and of the influence of the error of the slide block lower plane depth of parallelism to the smoothing generation, and product precision height, quality is good, and is very practical.

The technical solution of the utility model is: a kind of light face straight die, comprise upper bolster, die shoe and die shank, and die shank is arranged in the upper bolster, and the upper bolster lower surface is provided with the smoothing punch, and die shank is the die shank that floats, and it cooperates with the smoothing punch by last spherical joint; Die shoe is provided with the smoothing table top, and the smoothing table top is connected with die shoe by the screw that resets, and cooperates with die shoe by the lower peripheral surface joint, is socketed with back-moving spring on the screw that resets.

As preferably, described upper bolster and die shoe adopt the Q235 steel to make.

As preferably, described smoothing punch adopts the CrWMn steel to make.

The beneficial effects of the utility model are: die shank of the present utility model cooperates with the smoothing punch by last spherical joint, the smoothing table top cooperates with die shoe by the lower peripheral surface joint, when smoothing, between die shank and the smoothing punch, and can relatively rotate between smoothing table top and the die shoe, thereby the error of the table top that reduces forcing press and the slide block lower plane depth of parallelism is to the influence of smoothing generation.Reset screw and back-moving spring can slow down the impact of smoothing punch to the smoothing table top, and helps the smoothing table top to reset.Upper bolster and die shoe adopt the Q235 steel to make.The smoothing punch adopts the CrWMn steel to make good combination property, long service life.Very practical.

Description of drawings

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

The specific embodiment

As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of light face straight die, comprise upper bolster 1, die shoe 2 and die shank 3, die shank 3 is arranged in the upper bolster 1, upper bolster 1 lower surface is provided with smoothing punch 9, and die shank 3 is the die shank that floats, and it cooperates with smoothing punch 9 by last spherical joint 5; Die shoe 2 is provided with smoothing table top 4, and smoothing table top 4 is connected with die shoe 2 by the screw 7 that resets, and cooperates with die shoe 2 by lower peripheral surface joint 6, is socketed with back-moving spring 8 on the screw 7 that resets.

In the present embodiment, as preferably, described upper bolster 1 and die shoe 2 adopt the Q235 steel to make.Described smoothing punch 9 adopts the CrWMn steel to make.
