Description

Up-down floating opposite punching die

Technical Field

The utility model relates to the technical field of mold, especially, relate to an upper and lower formula offset die that floats.

Background

Moulds (Mule) are used for obtaining various moulds and tools of required products by injection moulding, blow moulding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother".

The hydraulic valve rod is commonly used in large-scale heavy machinery, and the hydraulic valve rod is provided with a plurality of oil leakage holes, and the common processing to the valve rod oil leakage hole is processed by the CNC lathe, and the expense is high and the processing is of a specified duration, and the productivity is also low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems existing in the prior art and providing an up-down floating offset die.

The technical scheme is as follows: the utility model provides a floating opposite punching die of upper and lower formula, includes mould, lower mould, goes up and presses the seat and press the seat down, it is provided with a drift all to move about in seat and the lower seat of pressing, and two the drift position is corresponding to go up and press the seat and press down inside its length direction to be provided with a plurality of square grooves and go into the piece, go up and press the seat and press down all through spring respectively in top board and holding down plate swing joint, be provided with the guide pillar in the spring.

Furthermore, the upper pressing seat and the lower pressing seat are respectively locked with the upper die and the lower die through equal-height screws.

Furthermore, the top of the punch is positioned in the square groove, and the inlet block penetrates through the square groove and the top of the punch.

Further, the length of the square groove is smaller than that of the top of the punch.

Furthermore, a plurality of mounting holes are formed in the top of the upper die.

Compared with the prior art, the utility model discloses possess following beneficial effect:

the utility model discloses a top board, holding down plate, drift, square groove, income piece and the mutually supporting of mounting hole, carry out stamping forming simultaneously to the oil leak hole on the hydraulic valve rod, reduce enterprise's manufacturing cost, shorten process time, to the punching press simultaneously about the hydraulic valve rod, improve the productivity of hydraulic valve rod processing.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 to 3, a vertical floating opposite-punching die includes an upper die 1, a lower die 2, an upper pressing base 3 and a lower pressing base 4, wherein a punch 7 is movably disposed in the upper pressing base 3 and the lower pressing base 4, and the two punches 7 punch a hydraulic valve rod simultaneously under the driving of the upper pressing base 3 and the lower pressing base 4, so as to improve the punching efficiency of the hydraulic valve rod; the two punches 7 correspond to each other in position, so that the simultaneous opposite punching is realized; a plurality of square grooves 9 and an inlet block 10 are arranged in the upper pressing seat 3 and the lower pressing seat 4 along the length direction of the upper pressing seat and the lower pressing seat, the square grooves 9 are used for placing the punch 7, the inlet block 10 penetrates through the punch 7, the movable connection between the punch 7 and the upper pressing seat 3 is realized, the punch 7 can be conveniently detached at any time, and the punch 7 can be replaced or maintained; the upper pressing seat 3 and the lower pressing seat 4 are movably connected with the upper pressing plate 5 and the lower pressing plate 6 respectively through springs 12, guide pillars 13 are arranged in the springs 12, and the arrangement of the springs 12 enables the hydraulic valve rod to be buffered when being stamped, so that the hydraulic valve rod is prevented from being broken due to overlarge stamping force.

The upper pressing seat 3 and the lower pressing seat 4 are respectively locked with the upper die 1 and the lower die 2 through equal-height screws 8.

The top of the punch 7 is positioned in the square groove 9, and the inlet block 10 penetrates through the square groove 9 and the top of the punch 7.

The length of the square groove 9 is less than that of the top of the punch 7.

Go up mould 1 top and be provided with a plurality of mounting hole 11, be convenient for hoist and mount whole mould.

The working principle is as follows: the staff places the hydraulic valve rod that needs the punching press on holding down plate 6, and the mould begins work afterwards, goes up mould 1 and drives drift 7 downstream, and 2 drive drift 7 upstairs removals on the lower mould 2 of lower mould simultaneously, carries out the punching press simultaneously to the hydraulic valve rod of placing on holding down plate 6, can be simultaneously at hydrovalve rod upper surface and lower surface punching press out the oil leak hole simultaneously, improves the productivity of hydraulic valve rod processing.

The above embodiments are only for illustrating the technical conception and the features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All changes and modifications that come within the spirit of the invention are desired to be protected.
