Background
At present, the floating material feeding is very wide in the practical application of continuous die production, because the continuity of floating material and feeding is very important in ensuring the continuous production of progressive dies. In the progressive die, a traditional buoyancy lifting guide mechanism is formed by combining a guide pillar, a spring and a material guide strip, buoyancy lifting is guided through the guide pillar, the spring gives buoyancy lifting force, and feeding is guided through the material guide strip. But when the guide post, the spring and the material guiding strip are arranged in a narrow space, the space is relatively compact and crowded; in places with large space, if the spring is too far away from the guide post, the guide post is inclined to clamp the belt, and the floating is relatively troublesome to realize.

a limiting pin edge is arranged on the circumferential surface of one side of the upper part of the pin edge guide pillar, a material guide strip is horizontally and outwards arranged in the limiting pin edge, a guide ridge is processed on the circumferential surface of the other side of the lower part of the pin edge guide pillar, which is opposite to the guide ridge in diameter, and a nitrogen spring installation groove is formed in the lower end surface of the pin edge guide pillar;
a guide pillar mounting groove is vertically formed in the guide pillar fixing plate, the pin edge guide pillar penetrates through the guide pillar mounting groove, a stepped pressing plate mounting groove is formed in the upper edge of the guide pillar mounting groove, and a pressing plate is mounted in the pressing plate mounting groove; the guide post mounting groove is upwards provided with a guide groove opposite to the pressure plate, and the guide edge of the pin-side guide post is sleeved in the guide groove;
a nitrogen spring mounting hole and a counter bore are vertically formed in the die holder and are communicated up and down, a nitrogen spring is mounted in the nitrogen spring mounting hole and is upwards abutted against a pin-side guide pillar, and a guide pillar fixing plate is downwards fixedly connected with the die holder through a counter screw.
The invention relates to a floating guide mechanism, which is characterized by also comprising: the nitrogen spring mounting groove is a two-stage blind hole type, a thick hole at the middle lower part of the two-stage blind hole type nitrogen spring mounting groove is aligned with a nitrogen spring mounting groove of the two-stage blind hole type below the nitrogen spring mounting groove, and a thin blind hole at the upper part of the two-stage blind hole type nitrogen spring mounting groove is an eccentric hole; the upper end of the nitrogen spring is provided with an eccentric thimble which is aligned with an eccentric thin blind hole at the upper part in the nitrogen spring mounting groove with the two-stage blind hole type.
The die holder is provided with an oil leakage hole.
The nitrogen spring is connected with external nitrogen pressurization and deflation equipment.
The invention has the beneficial effects that: simple structure is ingenious, and convenient operation saves the cost, and the practicality is strong, and the security is high, changes in original structure, thereby has integrated guide pillar, spring and guide strip's position in the space and has saved space, can lead to the guide strip again when realizing the buoyancy lift.

FIG. 1 is a schematic view of the mold closed configuration of the present invention;
fig. 2 is a schematic structural view of the present invention when the mold is opened.
In the figure, 1, a pin edge guide post, 2, a guide post fixing plate, 3, a die holder, 4, a nitrogen spring, 5, a pressing plate and 6, a material guiding strip are arranged.
Detailed Description
Referring to fig. 1 and 2, the structure of the invention is that the invention comprises a pin edge guide post 1, a guide post fixing plate 2, a die holder 3 and a nitrogen spring 4,
a limiting pin edge is arranged on the circumferential surface of one side of the upper part of the pin edge guide pillar 1, a material guide strip 6 is horizontally and outwards arranged in the limiting pin edge, a guide ridge is processed on the circumferential surface of the other side of the lower part of the pin edge guide pillar 1, which is opposite to the diameter of the lower part of the pin edge guide pillar, and a nitrogen spring installation groove with two-stage blind hole types is arranged on the lower end surface of the pin edge guide pillar 1;
a guide pillar mounting groove is vertically formed in the guide pillar fixing plate 2, the pin edge guide pillar 1 penetrates through the guide pillar mounting groove, a stepped pressing plate mounting groove is formed in the upper edge of the guide pillar mounting groove, a pressing plate 5 is mounted in the pressing plate mounting groove, and the pressing plate 5 is used for limiting the upward separation of the guide groove, so that the pin edge guide pillar 1 is limited by limiting the nitrogen stroke; the guide post mounting groove is upwards provided with a guide groove opposite to the pressure plate 5, and the guide edge of the pin-side guide post 1 is sleeved in the guide groove, so that the pin-side guide post 1 can slide up and down in the guide post mounting groove without rotating;
a nitrogen spring mounting hole and a counter bore are vertically formed in the die holder 3, the nitrogen spring mounting hole and the counter bore are vertically communicated, a nitrogen spring 4 is mounted in the nitrogen spring mounting hole, the nitrogen spring 4 is upwards abutted with the pin-side guide pillar 1, and an oil leakage hole is formed in the die holder 3; the guide post fixing plate 2 is fixedly connected with the die holder 3 downwards by using a countersunk head screw.
The thick hole at the middle lower part of the nitrogen spring mounting groove with the two-stage blind hole type is aligned with the nitrogen spring mounting groove with the two-stage blind hole type at the lower part, and the thin blind hole at the upper part of the nitrogen spring mounting groove with the two-stage blind hole type is an eccentric hole; the upper end of the nitrogen spring 4 is provided with an eccentric thimble which is aligned with an eccentric thin blind hole at the upper part in the nitrogen spring mounting groove with the two-stage blind hole type upwards, so that the pin edge guide pillar 1 cannot rotate when ascending.
The nitrogen spring 4 is connected with an external nitrogen pressurization and deflation device.
As shown in fig. 2, when the mold needs to be opened for work, the nitrogen spring 4 acts, the pin edge guide pillar 1 floats upwards under the stretching action of the nitrogen spring 4 until the guide ridge at the lower part of the pin edge guide pillar 1 is limited by the pressing plate 5 (meanwhile, the ejector pin slides with the eccentric thin blind hole at the upper part in the two-stage blind hole type nitrogen spring installation groove to ensure that the pin edge guide pillar 1 cannot rotate), at the moment, the nitrogen spring 4 reaches the upper limit of the floating stroke, the pin edge guide pillar 1 rises and the pin edge guide pillar 1 cannot rotate circumferentially, so that the guide strip 6 reaches the preset height along with the pin edge guide pillar to realize the floating and the guiding.
