Abstract
The utility model discloses a bending female die, which is characterized in that an introducing inclined plane is arranged at the port of the groove, two angles of which are both provided with an arc-shaped groove parallel to the groove axis which are provided with a rolling needle matching the diameter of the groove axis. The circular arcs of the exposed part of the rolling needles are both arranged in the included angles of the two extending surfaces of the angles. The bending female die has the advantages of no scratches on the product, long service life and lower cost.
Description
Technical field
The utility model relates to a kind of bending die, especially for the bending die of vehicle shock absorber knuckle carriage.
Background technology
At present, as shown in Figure 1, be widely used in the bending die 6 of vehicle shock absorber knuckle carriage, be provided with groove, be provided with fillet R in the corner of groove oral area, product 7 is subjected to bigger sliding friction power at fillet R place in the process of bending, product 7 surfaces are easy to be scratched, simultaneously fillet R is also easy to wear, needs often polish the fillet position, causes that die shortens service life, cost increases.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of long, lower-cost bending die of product, service life that can not scratch is provided.
For achieving the above object, a kind of bending die of the present utility model, be provided with groove, it is characterized in that being provided with the importing inclined-plane at the oral area of groove, be equipped with the arc groove parallel in two corners that import the inclined-plane with recess axis, be provided with the needle roller that is complementary with its diameter in the arc groove, the circular arc of needle roller exposed parts all is positioned at the angle of these corner two outer faces;
Product is in the process of bending, and needle roller can freely rotate in arc groove, and original force of sliding friction is changed over force of rolling friction, has reduced frictional force greatly, has avoided product surface to be scratched;
As further improvement of the utility model, the baffle plate that blocks two arc grooves is installed on the end face of die; Can position convenient the use to two needle rollers;
In sum, use the utility model can not scratch product, have long, lower-cost advantage in service life simultaneously.
Description of drawings
Fig. 1 is the front view of existing bending die user mode.
Fig. 2 is the front view of the utility model user mode.
Fig. 3 is the partial enlarged drawing at I place among Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
By Fig. 2 and shown in Figure 3, this bending die 1 is provided with groove, oral area at groove is provided with importing inclined-plane 2, be equipped with the arc groove parallel in two corners that import the inclined-plane with recess axis, be provided with the needle roller 3 that is complementary with its diameter in the arc groove, the circular arc of needle roller 3 exposed parts all is positioned at the angle of these corner two outer faces, and the baffle plate 4 that blocks two arc grooves is installed on the end face of die 1;
Claims (2)
1. bending die, be provided with groove, it is characterized in that being provided with the importing inclined-plane at the oral area of groove, be equipped with the arc groove parallel in two corners that import the inclined-plane with recess axis, be provided with the needle roller that is complementary with its diameter in the arc groove, the circular arc of needle roller exposed parts all is positioned at the angle of these corner two outer faces.
