Drawings

Embodiments of the present invention are described below with reference to the accompanying drawings, in which:

fig. 1 is a schematic structural diagram of a bearing with a circular spring pier die.

Fig. 2 is the utility model provides a pair of spring mound circle mould's schematic structure view.

Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a bearing using a spring pier circular mold of the present invention. The bearing comprises a bearing body 10, and both ends of the bearing body 10 are provided with a first interface 11 and a second interface 12. The first port 11 is provided with a plurality of first recesses 111 and first protrusions 112, and the second port 12 is provided with a plurality of second protrusions 121 and second recesses 122 corresponding to the first recesses 111 and the first protrusions 112. The first notch 111 and the first boss 112 and the second boss 121 and the second notch 122 matched with the first notch and the first boss 112 ensure that the position of the first connector 11 and the position of the second connector 12 are ensured when the bearing body 10 is subjected to the heading circle, so that the first connector and the second connector are inserted in a staggered manner, and the quality of products subjected to the heading circle is improved.

Please refer to fig. 1 and fig. 2, wherein fig. 2 is a schematic structural diagram of a spring pier circle mold according to the present invention. The spring upsetting circular die comprises an upper die 21, a lower die 22 positioned below the upper die 21, and a sub die 23 arranged on the upper die 21. The bottom of the upper die 21 is provided with a first arc-shaped groove 26, the top of the lower die 22 is provided with a second arc-shaped groove 27, the middle of the first arc-shaped groove 26 is provided with a notch 28 for the sub-die 23 to move up and down, and the top of the sub-die 23 is connected with the upper die 21 through a spring 32. The bottom of the sub-die 23 is provided with a third arc-shaped groove 29. At least one first guide post 31 is connected between the upper die 21 and the lower die 22, the first guide post 31 is arranged such that the movement locus of the upper die 21 and the lower die 22 is limited, and structurally, the first guide post 31 may be a cylinder or a prism. Preferably, the number of the first guide posts 31 is two, and the two first guide posts 31 can prevent the upper die 21 and the lower die 22 from rotating relatively. The top of the sub-mold 23 is further provided with at least one second guide post 33 connected with the upper mold 21. When the third arc-shaped slot 29 of the sub-die 23 abuts the first interface 11 and the second interface 12, the spring 32 at the top of the sub-die 23 is compressed, and the sub-die 23 moves upward in the notch 28 along the second guide post 33 because the spring 32 is compressed. When the spring 32 is not compressed, the top surface of the sub-die does not protrude out of the notch 28. A groove (not shown) is arranged on the inner wall of the notch 28, a lug (not shown) is arranged on the side surface of the sub-die 23 corresponding to the groove, the lug is movably positioned in the groove, so that the spring 32 is used for connecting the upper die 21 and the sub-die 23, and the matching of the lug and the groove ensures that the traveling route of the sub-die 23 is limited and moves up and down in the notch 28.

A buffer layer 34 is further arranged on the bottom surface of the upper die 21 and the top surface of the lower die 22. The buffer layer 34 is made of rubber materials, and when the upper die 21 and the lower die 22 are pressed, a certain buffer effect can be achieved, and the pier circle quality is improved.

In this embodiment, the bearing body 10 is placed in the second arc-shaped groove 27, and the first and

second ports

11 and 12 of the bearing body 10 are abutted against the third arc-shaped groove 29. When the upper die 21 moves towards the lower die 22, since the first and

second ports

11, 12 first touch the third arc-shaped groove 29, since the arc length of the sub-die 23 is relatively small, it only touches the bearing walls of the first and

second ports

11, 12 when the sub-die is rounded. The first interface 11 and the second interface 12 are extruded to be flush through slow extrusion, at the moment, the spring 32 at the top of the sub die 23 is compressed, the sub die 23 rises in the notch 28, and the condition that the first interface 11 and the second interface 12 are not flush due to the fact that the first interface 11 and the second interface 12 contact the upper die 21 successively is avoided.

Compared with the prior art, the utility model provides a pair of spring mound circle mould goes up mould 21 through one that sets up, a lower mould 22 and a submodule 23 that sets up on last mould 21 go up the bottom of mould 21 and set up first arc wall 26, set up second arc wall 27 at the top of lower mould 22, a notch 28 that can supply submodule 23 activity from top to bottom is seted up at the middle part of first arc wall 26, the top of submodule 23 pass through spring 32 with it connects to go up mould 21, the bottom of submodule 23 is equipped with a third arc wall 29. So with first,

second interface

11, 12 of bearing body 10 earlier with third arc wall 29 contact makes first,

second interface

11, 12 flush, by again go up mould 21 with lower mould 22 is with the bearing mound circle, simple structure, the simple operation has avoided the interface that leads to because of the interface atress time is inconsistent effectively uneven, and the condition that the rejection rate is high appears.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
