Abstract

The utility model discloses a pressing die for cone steel plates. The pressing die comprises an upper die body and a lower die body, wherein the upper die body is provided with a protruding cone-shaped punch; the lower die body is provided with a cone-shaped punch die which is matched with the cone-shaped punch; the two ends of the punch die body are provided with limiting boards; and when pressing, the punch is positioned between the two limiting boards. By using the pressing die, the cone steel plates can be formed by one-time pressing, and the quality and precision of products are upgraded.

Description

A kind of cone steel plate compacting tool set

Technical field

The utility model relates to the steel plate compacting tool set, relates in particular to a kind of cone steel plate compacting tool set.

Background technology

At present, the part kind that needs on various machines or the equipment is a lot, and especially the demand of cone class part is larger.In the prior art, it is that the machining benchmark line is processed that general employing launches the quadrat sampling line with cone, be arranged in order the form close from outward flange to minute center line by datum line and produce cone object, the defective that but such processing mode exists and time-consumingly takes a lot of work, labour intensity is large, Product Precision is low and working (machining) efficiency is low, especially the cone back cut diameter is little, the characteristics that lower port diameter is large cause difficulty of processing to increase, and, circular arc and upper and lower opening diameter do not reach quality requirement, will cause secondary operations, thereby increase production cost.

In order to address the above problem, following patented technology has been proposed in the prior art:

China Patent No. " 200720198705.4 " discloses a kind of conical steel plate die, and its open day is on December 03rd, 2008.Its technical scheme comprises a mold and a bed die, and this mold is provided with an outstanding cone drift, and this bed die is provided with a cone punch die that is used in conjunction with this cone drift.

But the prior art take above-mentioned patent document as representative, in actual use, still have the following disadvantages: one, steel plate to be punched re-uses machine after red with electric welding weldering and is placed on the bed die, because the temperature of steel plate to be punched is higher, inconvenient punch die on steel plate to be punched and the bed die is aligned, thereby cause that the cone plate quality that stamps out is poor, precision is low; Two, because the speed of drift punching press when touching steel plate to be punched, will make steel plate to be punched be shifted in punch die, cause the punching press failure, still need two times punch, increased production cost.

Summary of the invention

The purpose of this utility model is to solve the problems referred to above that prior art light plate compacting tool set exists, a kind of cone steel plate compacting tool set is provided, after adopting the utility model, the cone steel plate not only can be disposable compressing, also improved quality and the precision of product.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of cone steel plate compacting tool set, comprise mold and bed die, be provided with the tapered punch of protrusion on the mold, be provided with the taper punch die with the tapered punch coupling on the bed die, it is characterized in that: the two ends of described punch die are provided with limiting plate, and drift is between two limiting plates when punching press.

Described limiting plate top protrudes from the upper surface of bed die.

Described limiting plate and bed die are integrated.

Described bed die caves inward and forms the taper punch die.

Compare for the prior art of " 200720198705.4 " with China Patent No., employing the utility model has the advantage of:

One, in the utility model, owing to being provided with limiting plate at the two ends of described punch die, and drift is between two limiting plates when punching press, therefore, the steel plate to be punched after the heating is placed on when rushing to, because the effect of limiting plate, steel plate is limited in the punch die, patrix not only can be disposable compressing, and steel plate to be punched can not move yet when compacting, has improved quality and the precision of product.

Two, in the utility model, described limiting plate top protrudes from the upper surface of bed die, this structure is between two limiting plates steel plate to be punched all the time when punching press, prevent that part steel plate to be punched from exceeding the punch die border, further improved quality and the precision of product.

Three, in the utility model, described limiting plate and bed die are integrated, and this structure has improved the stability of limiting plate and bed die, and is improved its service life.

Four, in the utility model, described bed die caves inward and forms the taper punch die, because punch die the is bed die formation that caves inward, so punch die and bed die are complete one, not only can bear the larger impulsive force of drift, also make the plate quality of compacting better.

Five, adopt the utility model to make the cone Sheet Forming Ability good, manufacturing cost reduces, and the quality of product and precision are high, are conducive to improve company competitiveness.

Description of drawings

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

Fig. 2 is the structural representation of bed die in the utility model.

Be labeled as among the figure: 1, mold, 11, drift, 2, bed die, 21, punch die, 3, steel plate, 4, limiting plate.

The specific embodiment

A kind of cone steel plate compacting tool set, comprise mold 1 and bed die 2, be provided with the tapered punch 11 of protrusion on the mold 1, be provided with the taper punch die 21 with tapered punch 11 couplings on the bed die 2, the two ends of described punch die 21 are provided with limiting plate 4, and drift 11 is between two limiting plates 4 when punching press.

Preferred embodiment of the present utility model is that described limiting plate 4 tops protrude from the upper surface of bed die 2, but are not limited to above-mentioned set-up mode.

Another preferred embodiment of the present utility model is, described limiting plate 4 is integrated with bed die 2, limiting plate 4 also can with bed die 2 split type settings.

Another preferred embodiment of the present utility model is, described bed die 2 caves inward and forms taper punch die 21, but is not limited to above-mentioned set-up mode, and taper punch die 21 also can protrude from the upper surface of bed die 2.

In the utility model, also can change drift 11 and punch die 21 into cylinder, ellipsoidal shape etc., be not limited to cone drift 11 and punch die 21.

Operation principle of the present utility model:

Steel plate 3 usefulness electric welding weldering to be punched is red, reach can thermal process status the time, it is placed on the punch die 21 of bed die 2, because the effect of limiting plate 4, the two ends of steel plate 3 to be punched are positioned on the punch die 21, and the power set of this mold 1 adopt hydraulic system, when the temperature of steel plate 3 to be punched also is in best shaped state, start mold 1, disposable stamping, the compacting of cone steel plate is finished.
