Abstract
The utility model relates to a notching device for a precision high-speed stamping mold, which belongs to the technical field of the stamping tool. The notching device for the precision high-speed stamping mold comprises a notching core mold, a holding pad and a cavity mold plate, and is characterized in that a lower mold plate is provided with a bulge which can prevent the holding pad from tilting, and the bulge is arranged in a way of corresponding to the holding pad. The utility model can eliminate the influence of unstable formation, unstable external pressure, mold plate deformation and the like caused by punching centralization, and has the advantages of simple structure, convenient operation, high notching depth precision, high notching stability, wide scope of application and the like.
Description
Technical field
The utility model belongs to punching press bed accessory technical field, particularly relates to a kind of scratching device that is used for the high speed and precision diel.
Background technology
At present, score structure is a structure commonly used in the diel, generally be commonly used on the sign of stamping parts surface, size to indentation, the degree of depth does not have the accurate dimensions requirement, but in the diel of battery anti-explosion sheet, the stability of width of nick is the important component part that ensures Product Safety and prevent accidental explosion.The size of explosion-proof ring in the production of battery anti-explosion sheet, the degree of depth directly affect the explosion-proof value of battery and the stability of explosion-proof pressure, and traditional score structure is stamped in the shape of indentation punch on the surface of stamping parts as shown in Figure 3.Comprising indentation punch 1 ', holding pad 2 ', stamping parts 3 ', concave template 4 ', forming convax mould 5 '.Fig. 4 is the state of Center of Pressure when concentrating.
The problem that the tradition score structure exists is: (1) diel is when producing, intensive collection of punching or the pressure that has the position of moulding to need are bigger, the Center of Pressure is concentrated in the position of moulding, and holding pad has the depth dimensions of the obliquity effects indentation of trace, as shown in Figure 2.(2) press pressure is unstable aborning can influence the depth accuracy of indentation on stamping parts.
Summary of the invention
The utility model provides a kind of scratching device that is used for the high speed and precision diel for solving the technical problem that exists in the known technology.
The purpose of this utility model provides a kind of scratching device that is used for the high speed and precision diel with characteristics such as simple in structure, easy to operate, width of nick precision height, indentation good stability and applied ranges.
The indentation mould of the utility model precision is complete closing structure, on lower bolster, protrude several small columns, when work, holding pad is pushed down material, after holding pad and the complete closure of concave template, keep certain clearance between the cylinder of protrusion and the holding pad, last mould is closed fully, the indentation punch is pressed into the shape of front end in the raw material, and the indentation punch reaches design size.When stamping-out in the mould was concentrated or moulding is arranged, the Center of Pressure concentrated on any and causes holding pad to tilt, and at this moment protruded cylinder support holding pad counteracting partial pressure and made stress equalization, guaranteed that the indentation punch is carved into the depth accuracy of stamping parts.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of scratching device that is used for the high speed and precision diel comprises indentation punch, holding pad and concave template, is characterized in: lower bolster is provided with the projection that prevents that holding pad from tilting, the corresponding assembling with holding pad of projection.
The scratching device that the utility model is used for the high speed and precision diel can also adopt following technical scheme:
The described scratching device that is used for the high speed and precision diel is characterized in: projection is cylinder.
The described scratching device that is used for the high speed and precision diel, be characterized in: cylinder is distributed in around the lower bolster.
The described scratching device that is used for the high speed and precision diel is characterized in: the difference that cylinder protrudes template height and stamping parts thickness is 0.015-0.03mm.
Advantage and the good effect that the utlity model has are:
Be used for the scratching device of high speed and precision diel owing to adopted the technical solution of the utility model, compared with prior art have the following advantages:
Elimination is concentrated by stamping-out and is had the influence of moulding to guarantee the width of nick precision.The difference that material thickness and cylinder protrude template part is 0.02mm, influence concentrated owing to stamping-out or moulding is stressed run-off the straight when punching press, realize mould rigidity closure by protruding cylinder when mould is closed fully, the strength of opposing run-off the straight guarantees the stable of mint-mark punch.
Eliminate the influence that the ambient pressure instability causes indentation.Forcing press can be subjected to voltage aborning, the influence of air pressure, the force value of moment increases, the closed fully increased pressure of offsetting in the 0.02mm gap when pressure increases between the template, guarantee that the degree of depth that punch is carved into stamping parts can not increase, to guarantee the stability of width of nick.
Multiple spot protrudes column type and supports the influence of elimination template deformation to width of nick.Adopt the multiple spot column type to support, eliminated because the stencil plane degree is poor the closed influence that sternly the width of nick precision is not caused.

The specific embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Consult accompanying drawing 1, Fig. 2, Fig. 3 and Fig. 4.
Embodiment 1
A kind of scratching device that is used for the high speed and precision diel comprises indentation punch 1, forming convax mould 5, holding pad 2 and concave template 4, and its concave template 4 is provided with cylinder 6 projectioies that prevent that holding pad 2 from tilting, and cylinder is distributed in around the lower bolster.The corresponding assembling with holding pad of cylinder 6 projectioies, cylinder 6 protrusion concave templates 4 height are 0.02mm with the difference of stamping parts 3 thickness.
The scratching device that is used for the high speed and precision diel of embodiment 1 is used.Figure 2 shows that the high-accuracy high-speed stamping die structure of battery anti-explosion sheet.
Accurate indentation mould is complete closing structure, on lower bolster, protrude several small columns, when work, holding pad is pushed down material, after holding pad and the complete closure of concave template, the cylinder of protrusion and the gap between the holding pad are 0.02mm, and last mould is closed fully, the indentation punch is pressed into the shape of front end in the raw material, and the indentation punch reaches design size.When stamping-out in the mould was concentrated or moulding is arranged, the Center of Pressure concentrated on any and causes holding pad to tilt, and at this moment protruded cylinder support holding pad counteracting partial pressure and made stress equalization, guaranteed that the indentation punch is carved into the depth accuracy of stamping parts.
