Abstract

The utility model discloses a lever-type pressing and riveting die which comprises a die holder, a lower die plate, a bracket, an upper die plate and a return spring, wherein the lower die plate is fixed on the die holder and extends forward; the bracket is fixed on the die holder; the upper die plate is pivoted on the bracket through a pin shaft and extends forward; the return spring is arranged below the upper die plate; a pressure-bearing head is arranged at the front end of the lower die plate; and a die head is arranged at the position where the front end of the upper die plate corresponds to a riveting-pressing position notch. The lever-type pressing and riveting die has the advantages that the throat depth of pressing and riveting equipment is increased, the application range of the pressing and riveting equipment is widened, and the utilization rate of the pressing and riveting equipment is improved.

Description

A kind of lever mould that presses

Technical field

The utility model belongs to the parts technical field that presses, and relates in particular to be used in the press mould that presses of nail of being used on the equipment of pressing.

Background technology

Usually, PEM(clamp nut) counterdie that presses of the mould that presses of element only has die holder and cylindrical die to constitute.This mould that presses only is suitable for simple in structure, the single ironware that presses.

For some complex structures and the bigger part of submission, the situation that the equipment throat depth is not enough or die holder is interfered that presses appears through regular meeting, and the common mould that presses can't be realized the work of pressing.

The utility model content

For this reason, technical problem to be solved in the utility model provides a kind of lever mould that presses, and can utilize this mould that presses to increase the throat depth of the equipment of pressing, and increases the equipment range of application and improves utilization rate of equipment and installations.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of lever mould that presses, it is characterized in that: the lower bolster that comprises die holder, is fixed on the die holder and stretches out forward, be fixed on the support on the die holder, be hubbed on the support and cope match-plate pattern that stretches out forward and the returning spring that is positioned at the cope match-plate pattern below by the pin axle, described lower bolster front end has pressure bearing head, and the position of the corresponding riveting locating notch of described cope match-plate pattern front end has die head.

For fear of the distortion of product riveting, described pressure bearing head is " L " shape.

Adopt technique scheme, the utility model can effectively increase the throat depth of the equipment of pressing, and interferes the position as stepping down fully to part, and the assurance work of pressing can normally be carried out.And the pressure bearing head of " L " shape to from the limit nearer pressing play position-limiting action, prevent to cause the extrusion deformation phenomenon owing to too closely pressing from the limit.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described:

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

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the utility model occupation mode schematic diagram.

Among the figure: 100-die holder, 200-lower bolster, 201-pressure bearing head, 300-support, 400-cope match-plate pattern, 500-returning spring, 600-pin axle, 700-die head, 10-product, 801-bolt, 802-pin, 001-squeeze riveter, 011-hydraulic stem.

The specific embodiment

As shown in Figure 1 and Figure 2, the lever of the present utility model mould that presses comprises die holder 100, lower bolster 200, support 300, cope match-plate pattern 400, returning spring 500.

Wherein lower bolster 200 is fixed on die holder 100 by pin 802 and front end stretches out forward, and front end has the pressure bearing head 201 of " L " shape.Support 300 also is fixed on die holder 100 by pin and is positioned at the rear portion of lower bolster 200, cope match-plate pattern 400 is hubbed on the support 300 by pin axle 600, front end stretches out forward with pin axle 600 pivot points and forms a lever construction, position at the corresponding pressure bearing head 201 of front end has die head 700, returning spring 500 is located at the below of cope match-plate pattern 400, is positioned at the anterior position of support 300.

It more than is exactly the lever of the present utility model mould that presses, when this mould that presses uses, this mould that presses is fixed on the squeeze riveter 001 with bolt 801, again as shown in Figure 3, the position that presses of product 10 is placed on the pressure bearing head 201 of lower bolster 200,011 pair of cope match-plate pattern 400 of hydraulic stem by squeeze riveter 001 is exerted pressure (force application location and direction are shown in Fig. 3 arrow), and the die head 600 on the cope match-plate pattern 400 just can press.

Because the above-mentioned mould that presses is a lever-type structure, this has just effectively increased the throat depth of the equipment that presses, and interferes the position as stepping down fully to part, and the assurance work of pressing can normally be carried out.And the pressure bearing head of " L " shape to from the limit nearer pressing play position-limiting action, prevent to cause the extrusion deformation phenomenon owing to too closely pressing from the limit.

Therefore, by foregoing detailed description, can find that lever riveting die of the present utility model has increases the equipment throat depth that presses, and increases to press the equipment range of application and improve the advantage of the utilization rate of equipment and installations that presses.

Claims

1. lever mould that presses, it is characterized in that: the lower bolster that comprises die holder, is fixed on the die holder and stretches out forward, be fixed on the support on the die holder, be hubbed on the support and cope match-plate pattern that stretches out forward and the returning spring that is positioned at the cope match-plate pattern below by the pin axle, described lower bolster front end has pressure bearing head, and the position of the corresponding riveting locating notch of described cope match-plate pattern front end has die head.

2. the lever according to claim 1 mould that presses is characterized in that: described pressure bearing head is " L " shape.
