Description

Telescopic guide mechanism of stamping die

Technical Field

The utility model belongs to the technical field of stamping die, a telescopic guide mechanism of stamping die is related to.

Background

At present, all the sheets of the press dies need to be stably and reliably guided, but not all the dies have enough space for installing the guide blocks. The traditional blanking die is generally provided with a floating material block at the bottom of a material sheet, and material guide strips are arranged on two sides of the material sheet, most of the material guide strips are one-to-one punched, and if one-to-two punched materials are needed, insufficient product guide and insufficient installation space of the floating material block can be caused.

Therefore, it is necessary to develop a structure requiring a small space to realize the aforementioned problem of insufficient space.

SUMMERY OF THE UTILITY MODEL

The utility model provides a telescopic guide mechanism of stamping die has solved the structure that exists among the prior art unreasonable for the product direction is not enough and not enough flotation block installation space's problem is solved.

The technical scheme of the utility model is that, a telescopic guide mechanism of stamping die, including the slider fixing base, the slider fixing base is fixed mounting on the die holder downwards, the slider is vertically sheathed on the upper surface of the slider fixing base, the upper part of the vertical surface of both sides of the slider is fixed with a guide strip mounting bracket respectively forward, the front ends of the two guide strip mounting brackets are fixedly connected with a guide strip together, the two guide strip mounting brackets and the guide strip together form a bearing frame, the upper part of the bearing frame is just opposite to the driving block; a nitrogen gas kicking block is installed to the rear end of slider fixing base, is provided with a nitrogen gas spring between nitrogen gas kicking block and the slider.

The utility model discloses a telescopic guide mechanism of stamping die, its characterized in that still lies in: the upper surface of the sliding block fixing seat is respectively provided with a wear-resisting plate along the longitudinal two sides, and the wear-resisting plates are clamped on the vertical surfaces of the two sides of the sliding block.

The utility model has the advantages that: the structure is simple and ingenious, the installation and the maintenance are convenient, and the practicability is strong; along with the motion of opening and shutting of mould and work, for the tablet provides reliable and stable direction, the space occupies fewly, and it is convenient to dismantle the debugging, has improved daily production's efficiency.

Drawings

FIG. 1 is a schematic view of a side-directional three-dimensional structure of the device of the present invention;

FIG. 2 is a schematic perspective view of the device of the present invention in the other side direction;

fig. 3 is a schematic structural diagram of the device of the present invention in two states, wherein the left diagram is a mold opening state and the right diagram is a mold closing state.

In the figure, the device comprises a driving block 1, a sliding block 2, a sliding block 3, a sliding block fixing seat 4, a material guiding strip 5, a material guiding strip mounting frame 6, a wear-resisting plate 7, a nitrogen spring 8 and a nitrogen top block.

Detailed Description

As shown in fig. 1 and 2, the structure of the utility model is that, the structure comprises a slider fixing seat 3, the slider fixing seat 3 is fixedly installed on a lower die holder downwards, the slider fixing seat 3 is made of brass, a slide rail type cavity is longitudinally arranged on the upper surface of the slider fixing seat 3, a slider 2 is sleeved in the cavity in a sliding manner, a guide bar mounting rack 5 is respectively fixed on the upper parts of the vertical surfaces of the two sides of the slider 2 forwards, the front ends of the two guide bar mounting racks 5 are fixedly connected with a guide bar 4 together, the two guide bar mounting racks 5 and the guide bar 4 form a bearing frame together, and the driving block 1 is just above the bearing frame; a nitrogen gas kicking block 8 is installed to the rear end of slider fixing base 3, be provided with a nitrogen gas spring 7 between nitrogen gas kicking block 8 and the slider 2, an antifriction plate 6 is installed respectively along vertical both sides to the upper surface of slider fixing base 3, antifriction plate 6 centre gripping is at the both sides facade of slider 2 for the transverse gap of spacing slider 2 provides reliable and stable direction for the load frame, makes 2 suits of slider realize transverse orientation and longitudinal sliding on the die cavity of slider fixing base 3.

The utility model is integrally installed on the lower die base, the driving block 1 is correspondingly arranged above the bearing frame, and the driving block 1 is fixedly installed on the upper die base; the sliding block 2 and the driving block 1 adopt a flat wedge structure, and are processed with a matching inclined plane, so that the driving block 1 moves downwards to punch the driving sliding block 2 to move longitudinally. The upper die base and the lower die base need to be provided with pin holes and tooth holes so as to be conveniently assembled and connected with the related components.

The slider fixing seat 3 and the wear-resisting plate 6 are both made of brass and are smooth and wear-resistant.

As shown in fig. 3, the working principle of the present invention is:

the initial position of the sliding block 2 is positioned at the front part of the sliding block fixing seat 3, namely is far away from the nitrogen top block 8;

when the mold is opened, under the action of the nitrogen spring 7, the slide block 2 drives the bearing frame to move forwards (to move towards the left side of the figure 3), and the material guide strips 4 extend forwards to provide guidance for the material sheets;

when the die is closed, the driving block 1 is pressed downwards, the slide block 2 overcomes the acting force of the nitrogen spring 7 to drive the bearing frame to integrally retreat (move towards the right side of the figure 3) and the material guiding strips 4 retreat to provide blanking space by utilizing the wedge principle.

The utility model has the advantages of simple structure ingenious, convenient operation, the practicality is strong, fine solution blanking mould lead to the not enough problem of tablet direction because of need remain the product and cut off back blanking space.
