Abstract
The invention discloses a surface leveling die for punching parts and relates to a punching tool comprising an upper die holder, a lower die holder and a die shank. The die shank is disposed in the upper die holder. A leveling male die is disposed on the lower surface of the upper die holder. The die shank is a floating die shank which matches with the spherical surface of the leveling male die. The lower die holder is provided with a leveling top which is connected with the lower die holder through a return screw. A return spring is sleeved on the return screw. The middle of the leveling top is matched with the spherical surface of the lower die holder. The surface of each of the upper die holder, the upper die holder and the die shank is provided with a fiberglass anticorrosion layer. The surface leveling die for punching parts has the advantages that the influence of errors in parallelism between the top of the punch press and the lower plane of a slider upon leveling can be reduced, product precision is high, and product quality is high.
Description
Technical field
The present invention relates to a kind of diel, relate in particular to a kind of blanking part surface 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 thinner and surperficial workpiece that does not allow impression, generally be to adopt blanking part surface straight die to smooth.When using existing blanking part surface straight die to smooth, the impact 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 Product Precision is low.
Summary of the invention
For the problem that above-mentioned prior art exists, the invention provides a kind of blanking part surface straight die, the impact that the table top that can reduce forcing press and the error of the slide block lower plane depth of parallelism produce smoothing, the Product Precision height, quality is good.
Technical scheme of the present invention is: a kind of blanking part surface straight die, comprise upper bolster, die shoe and die shank, die shank is arranged in the upper bolster, and the upper bolster lower surface is provided with the smoothing punch, it is characterized in that: die shank is the die shank that floats, and it cooperates with smoothing punch sphere; Be provided with the smoothing table top on the die shoe, the smoothing table top is connected with die shoe by the screw that resets, and is socketed with back-moving spring on the screw that resets, and smoothing table top middle part cooperates with the die shoe sphere; Upper bolster, die shoe and die shank surface are respectively arranged with the Corrosion Protection of Fiber Reinforced Plastics layer.
As preferably, be provided with spherical joint on the smoothing punch, have the arc groove that cooperates with upper spherical joint on the die shank, be provided with the lower peripheral surface joint on the smoothing table top, have the arc groove that cooperates with the lower peripheral surface joint on the die shoe.
As preferably, described upper bolster and die shoe adopt the Q235 steel to make, and die shank adopts 45 steel to make, and described smoothing punch adopts the CrWMn steel to make.
The invention has the beneficial effects as follows: die shank of the present invention cooperates with the smoothing punch by upper 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 on the impact of smoothing generation.Reset screw and back-moving spring can slow down the smoothing punch to the impact of 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.Fiberglass is good anticorrosive material, and atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are had good resistivity, has prolonged service life of the present invention, and only needs at corresponding component external coating fiberglass, and manufacture craft is simple.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As one embodiment of the present invention, as shown in Figure 1, a kind of blanking part surface straight die, comprise upper bolster 1, die shoe 2 and die shank 3, die shank 3 is arranged in the upper bolster 1, and upper bolster 1 lower surface is provided with smoothing punch 9, die shank 3 is the die shank that floats, and it cooperates with smoothing punch 9 spheres; In the present embodiment, as preferably, be provided with spherical joint 5 on the smoothing punch 9, have the arc groove that cooperates with upper spherical joint 5 on the die shank, be provided with smoothing table top 4 on the die shoe 2, smoothing table top 4 is connected with die shoe 2 by the screw 7 that resets, and is socketed with back-moving spring 8 on the screw 7 that resets.Smoothing table top 4 middle parts cooperate with die shoe 2 spheres; In the present embodiment, as preferably, be provided with lower peripheral surface joint 6 on the smoothing table top 4, have the arc groove that cooperates with lower peripheral surface joint 6 on the die shoe 2.Upper bolster 1, die shoe 2 and die shank 3 surfaces are respectively arranged with the Corrosion Protection of Fiber Reinforced Plastics layer.Fiberglass is good anticorrosive material, and atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are had good resistivity, has prolonged service life of the present invention, and only needs at corresponding component external coating fiberglass, and manufacture craft is simple.
In the present embodiment, as preferably, described upper bolster 1 and die shoe 2 adopt the Q235 steel to make, and die shank adopts 45 steel to make, and described smoothing punch 9 adopts the CrWMn steel to make good combination property, long service life.
