Abstract

The utility model discloses a punching die for punching three locking points on an outer circle and relates to the field of punching dies. The punching die for punching the three locking points on the outer circle solves the problems that the positions and sizes of protrusions are not consistent, and the protrusions are too large or too small. The punching die for punching the three locking points on the outer circle comprises an upper die and a lower die, wherein the upper die is composed of a nut, a beating rod, a die handle, a base plate, a guiding and positioning sleeve and a protrusion puncher pin, and the lower die is composed of a male die, a screw and a lower die base. According to the punching die for punching the three locking points on the outer circle, due to the fact that two positioning holes are formed in the guiding and positioning sleeve, the die handle and the protrusion puncher pin can be positioned and fixed at the same time, and the uniformity, in the circumferential direction, of three machined locking points and the size consistency, in the radial direction, of the three machined locking points can be guaranteed; machining of materials can be achieved in a one-time mode, repeated punching is not needed, and the production efficiency is greatly improved; the structure is simple, the die assembly speed is high, and cost of the die is low. The punching die for punching the three locking points on the outer circle is suitable for the machining field.

Description

The stamping die of drawn cup 3 lock points
Technical field
The utility model relates to stamping die field, relates to specifically the stamping die of drawn cup 3 lock points.
Background technology
At present, punching press needle bearing with in installation form substantially realize by interference, but in the seat hole of some aluminum enclosure due to stressed impact, in work, there is the asking of bearing failure of the loosening generation in outer ring.Therefore some bearing outer rings arrange the salient point that 0.2mm is high in bottom, so that after bearing assemble, its salient point is embedded in the seat hole of bearing block, prevents the loosening of outer ring.Improve the dependability of bearing.Because the bulge quantity of salient point is less than normal, therefore how to solve salient point the uniformity such as position, size, prevent the problem of the too small inoperative and excessive interior fourth contact diameter that affects bearing of salient point, become to need at present a difficult problem for solution.
Utility model content
For solving the problems of the technologies described above, the utility model provides the stamping die of drawn cup 3 lock points.
The utility model solves the technical scheme that its technical problem adopts: the stamping die of drawn cup 3 lock points, comprising: upper die and lower die; Patrix is made up of nut, knockout rod, mould handle, backing plate, guide-localization cover and salient point drift; Counterdie is made up of punch, screw, die shoe; Wherein, described nut is positioned at the upstream of knockout rod, mould handle, backing plate, guide-localization cover and salient point drift are enclosed within on knockout rod from top to bottom successively, and described mould handle, backing plate, guide-localization is enclosed within corresponding position and has from top to bottom 3 identical locating holes and be connected by screw; Described guide-localization is enclosed within side and has 1 locating hole, has a detent, and fix by screw at the correspondence position of salient point drift; Described salient point drift is three bump structures of entirety; Three salient points of described salient point drift are arranged in the groove of guide-localization cover; Described punch and die shoe are connected by screw fixing.
Described three overall bump structures refer on salient point drift to have three identical salient points simultaneously, are adding man-hour, can three lock points of disposable punching.
Operation principle: first the groove in three salient point rotary alignment guide-localization covers in salient point drift, with marking closely the fixing salient point drift of screw, be then connected with other parts in die assembly; Mould is arranged on after punch press, slider of punch is descending, and the guide-localization cover in patrix is located product orientation, and slide block is to bottom dead centre, three salient points on salient point drift are clamp-oned the edge of product bottom, and bottom making, R angle place metal is radially protruding formation 3 lock points after being squeezed.Slide block is up, by knockout rod, product is applied to stripping force, and product comes off from guide-localization cover, completes product processing.Because 3 lock points form at guide-localization cover groove corresponding position, the therefore demoulding smoothly.
The beneficial effects of the utility model: one, put and have two locating holes at guide-localization in the utility model, can mould handle and salient point drift be positioned and be fixed simultaneously, can ensure that 3 lock points after processing are in the uniformity of circumferencial direction and lock in the same size radially; Two, adopt stamping die of the present utility model, can process at one time, do not need punching press repeatedly, greatly improved production efficiency; Three, stamping die of the present utility model, simple in structure, and dress mould speed is fast, and die cost is low.
Brief description of the drawings
Fig. 1 is the structural representation of three salient point stamping dies of the present utility model;
Fig. 2 is the finished product schematic diagram after processing;
Wherein, 1-nut, 2-knockout rod, 3-mould handle, 4-backing plate, 5-guide-localization cover, 6-salient point drift, 7-punch, 8-screw, 9-die shoe.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, below in conjunction with drawings and Examples, the utility model to be described in further detail, this embodiment, only for explaining the utility model, does not form and limits protection domain of the present utility model.
Embodiment
As shown in Figure 1, the stamping die of drawn cup 3 lock points, comprising: upper die and lower die; Wherein, patrix by nut 1, knockout rod 2, mould 3, backing plate 4, guide-localization cover 5 and salient point drift 6 form; Counterdie is made up of punch 7, screw 8, die shoe 9; Described nut 1 is positioned at the upstream of knockout rod 2, mould 3, backing plate 4, guide-localization cover 5 and salient point drift 6 be enclosed within on knockout rod 2 from top to bottom successively, described mould 3, backing plate 4, guide-localization overlap 5 and have from top to bottom 3 identical locating holes in corresponding position and connect by screw 8; Described guide-localization cover 5 has 1 locating hole in side, have a detent at the correspondence position of salient point drift 6, and fixing by screw 8; Described salient point drift 6 is three bump structures of entirety; Three salient points of described salient point drift 6 are arranged in the groove of guide-localization cover 5; Described punch 7 and die shoe 9 are connected and fixed by screw 8.
