Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention will be further described with reference to the drawings and the specific embodiments.

As shown in fig. 1 and 2, the utility model provides a roll up system copper sheathing turn-ups mould, including upper die base 1 and die holder 2, die holder 2 is fixed with turn-ups lower mould 3, and turn-ups lower mould 3 integrated into one piece is equipped with the portion of wearing to establish 4 that wears to locate system copper sheathing inner chamber, and the diameter of the portion of wearing to establish 4 up end slightly is greater than the diameter of the portion of wearing to establish 4 down end, and is provided with below the turn-ups and supplies to roll up system copper sheathing down end butt and bend into the butt face 5 of hem, is provided with first radius angle 6 between butt face 5 and the portion of wearing to establish 4; the lower terminal surface of the upper die base 1 is provided with a jack 7 for rolling a copper sleeve to be inserted, a material pushing rod 8 is connected in the jack 7 in a vertical sliding mode, the upper end surface of the rolled copper sleeve abuts against the lower end surface of the material pushing rod 8, a second fillet 9 is arranged at the lower end of the jack 7, and the second fillet 9 is smaller than the first fillet 6. When the rolled copper sleeve needs to be flanged, the rolled copper sleeve is sleeved into the penetrating part 4, then the upper die holder 1 is driven to move downwards through the punch press, so that the rolled copper sleeve penetrates through the jack 7, the upper end face of the rolled copper sleeve abuts against the material pushing rod 8, the rolled copper sleeve abuts against the first fillet 6 and is turned outwards under the action of pressure to form a flange, the flange abuts against the abutting face 5, and the flanging of the rolled copper sleeve is completed; because when rolling up the copper sheathing turn-ups, the system copper sheathing that is located jack 7 is pressed the effect and is produced deformation, and the system copper sheathing is close to the internal diameter that is less than the internal diameter of keeping away from hem one end near the hem position, and the diameter through wearing to establish 4 up end slightly is greater than the diameter of wearing to establish 4 lower terminal surface like this, produces deformation when guaranteeing to roll up the system copper sheathing turn-ups, guarantees that the internal diameter of rolling up the system copper sheathing is unanimous, improves the precision of system copper sheathing processing.

The material pushing rod 8 faces to one end of the lower die base 2 and is integrally formed to be an annular step 10, the outer side wall of the step 10 is attached to the side wall of the material pushing rod 8, and the upper end face of the penetrating portion 4 penetrates through an annular inner cavity of the step 10. When the rolled copper sleeve is flanged, the upper end face of the rolled copper sleeve abuts against the step 10, and the penetrating part 4 penetrates through the inner cavity of the step 10, so that the rolled copper sleeve can be kept round after being extruded, and the flanging qualification rate of the rolled copper sleeve is improved.

In order to conveniently determine the height of the rolled copper bush after flanging, the side wall of the insertion hole 7 is provided with a sliding groove 11, and the side wall of the pushing rod 8 is integrally formed with a convex block 12 which is connected with the sliding groove 11 in a sliding manner. When the convex block 12 is abutted to the lower bottom surface of the sliding groove 11, the lower end surface of the step 10 is flush with the lower end surface of the upper die base 1, and the sliding distance of the convex block 12 in the sliding groove 11 is consistent with the height of the rolled copper bush after flanging, so that the height of the rolled copper bush after flanging is conveniently ensured, and the processing accuracy of the rolled copper bush is improved.

In order to keep the flanged edge of the flanged copper sleeve to be round, the abutting surface 5 is lower than the upper end face of the lower die base 2, so that the abutting surface 5 and the diameter of the upper end face of the lower die base 2 form a groove 13 for storing the flanged edge, the groove 13 is annular, when the flanged copper sleeve is flanged, the flanged edge formed by bending the flanged copper sleeve is located in the groove 13, the flanged edge abuts against the side wall of the groove 13, the shape of the flanged edge is ensured to be circular, and the outer diameter of the flanged edge is convenient to control.

The lower terminal surface integrated into one piece of upper die base 1 is equipped with the bulge loop 14 of wearing to establish with recess 13, and bulge loop 14 surrounds in jack 7 to the bulge loop 14 inside wall flushes with jack 7, and the lateral wall slightly is less than recess 13 lateral wall. Therefore, the convex ring 14 penetrates through the groove 13 and abuts against the folded edge of the rolled copper sleeve, the folded edge of the rolled copper sleeve is kept flat, the upper die base 1 and the lower die base 2 are conveniently positioned, and the upper die base 1 and the lower die base 2 are ensured to be located at the same straight line position.
