Abstract
The utility model relates to a hole flanging terrace die structure and hole flanging mould, including hole flanging terrace die (1) and lower mould (3), hole flanging terrace die (1) sets up on the last calligraphy or painting model body, its characterized in that: the root of hole flanging terrace die (1) is provided with recess (11) so that hole flanging terrace die (1) forms the circular bead structure. Recess (11) are the equipartitions at the ring channel of hole flanging terrace die (1) root circumference or at the breach of respectively processing an indent of the root bilateral symmetry of hole flanging terrace die (1). The degree of depth h of recess (11) is 0.3mm. The hole flanging mould includes this hole flanging terrace die structure. The utility model provides a " hole flanging " later, the easy card of work piece is at the lower mould, the difficult problem of the drawing of patterns has improved the qualification rate in practical application.
Description
Technical field
The utility model belongs to the manufacturing technology field of automotive wheel, is specifically related to a kind of Burring Punch structure and hole flanging mold.
Background technology
" hole flanging " is one of technique common in steel plate cold stamping, and practical application is more.Sometimes rout up to ensure the hole come, there is good perpendicularity on its limit, hole relative to bottom surface, and it is less that hole flanging gap is arranged, and easily causes workpiece to be stuck in counterdie, causes the demoulding inconvenient.
Such as, steel wheel, its centre bore needs to closely cooperate with Automobile shaft, and require higher to the perpendicularity of centre bore, when " hole flanging ", steel wheel easily occurs that steel ring is stuck in the situation of counterdie, as shown in Figure 1 to Figure 3.
Utility model content
The utility model devises a kind of Burring Punch structure and hole flanging mold.After solving " hole flanging ", workpiece is easily stuck in counterdie, and demoulding problem not easily, improves qualification rate in actual applications.
In order to solve the technical problem of above-mentioned existence, the utility model have employed following scheme:
A kind of Burring Punch structure, comprise Burring Punch (1) and counterdie (3), Burring Punch (1) is arranged on mould body, it is characterized in that: the root of Burring Punch (1) is provided with groove (11) and forms shoulder structure to make Burring Punch (1).
Further, groove (11) is distributed on the cannelure of Burring Punch (1) root circle or the breach in the root of Burring Punch (1) monosymmetric each processing indent.
Further, the degree of depth h of groove (11) is 0.3mm.
A kind of hole flanging mold, is characterized in that: comprise above-mentioned arbitrary described Burring Punch structure.
This Burring Punch structure and hole flanging mold have following beneficial effect:
(1) after the utility model solves " hole flanging ", workpiece is easily stuck in counterdie, and demoulding problem not easily, improves qualification rate in actual applications.
(2) the utility model does not increase complicated tool locating, and technical scheme easily realizes, cost is low, substantially increases operating efficiency simultaneously.

Description of reference numerals:
1-punch; 11-groove; 2-steel ring; 3-counterdie;
The degree of depth of h-groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 4 and Fig. 5 shows a kind of Burring Punch structure and hole flanging mold, comprise Burring Punch 1 and counterdie 3, Burring Punch 1 is arranged on mould body, the root of Burring Punch 1 is provided with groove 11 and forms shoulder structure to make Burring Punch 1, the degree of depth h of groove 11 is about 0.3mm, like this when Burring Punch 1 moves upward due to groove 11 formed shoulder structure function, steel ring 3 can depart from counterdie smoothly.Groove 11 is distributed on the cannelure of Burring Punch 1 root circle or the breach in the root of Burring Punch 1 monosymmetric each processing indent.This punch structure and the hole flanging mold stripping result that forms thus good, greatly improve labor productivity.
The utility model does not increase complicated tool locating, and technical scheme easily realizes, cost is low, substantially increases operating efficiency simultaneously.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; obvious realization of the present utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all in protection domain of the present utility model without to improve.
Claims (4)
1. a Burring Punch structure, comprise Burring Punch (1) and counterdie (3), Burring Punch (1) is arranged on mould body, it is characterized in that: the root of Burring Punch (1) is provided with groove (11) and forms shoulder structure to make Burring Punch (1).
2. Burring Punch structure according to claim 1, is characterized in that: groove (11) is distributed on the cannelure of Burring Punch (1) root circle or the breach in the root of Burring Punch (1) monosymmetric each processing indent.
