The dodging type inclined wedge has the advantages of utilizing the rotating shaft provided with the spiral groove and the straight groove to achieve dodging of the rotating arm, enlarging space and enabling a finished piece to be taken out of a mold smoothly. A guide sleeve is matched with a guide pillar, thereby guaranteeing that a relative position of the finished piece is accurate. Design of the mold is more compact by adopting the nitrogen spring, and more space can be saved.
Description
Technical field
The utility model relates to a kind of automobile die, especially relates to a kind of formula wedge that gets out of the way.
Background technology
On pcketing and punching link, exist certain problem at car engine cover, automobile door lock lock nest: product is because stressed recessed to the inside; Cause being difficult for being removed, in order to take out product, generally more traditional method is that product is levered up to a recessed side; Or mould left the space of certain release product; But general mould all designs compactly, and it is very little to leave the space possibility that withdraws from product, so still can't overcome this type of problem.
Summary of the invention
The problem that the utility model will solve provides a kind of formula wedge that gets out of the way, and the taking-up of convenient processing back product has the advantages that to improve mould and die accuracy when simplifying mould structure.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of formula wedge that gets out of the way, comprise that the patrix of flexible connection drives voussoir and slide block, and slide block one end is connected with nitrogen spring; Turning cylinder passes casing and is connected with the other end of slide block; The other end of turning cylinder is connected with pivoted arm, and casing is provided with die, and pivoted arm is provided with drift and fixed head; Said turning cylinder is provided with helicla flute and straight slot.
Preferably, casing is provided with at least 2 guide pin bushings, and pivoted arm is provided with the guide pillar of respective numbers; The diameter of guide pillar is not more than the internal diameter of guide pin bushing.
Preferably, the contact-making surface of patrix driving voussoir and slide block is the inclined-plane.
Preferably, the rotational angle range of turning cylinder is the 0-90 degree.
Preferably, patrix drives voussoir and is provided with a hook, is located at the hook groove on the slide block accordingly.
Preferably, also has a nut in the dowel hole.
Preferably, the interstice coverage of guide pillars and bushes is the 0.005-0.1 millimeter.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, utilize the turning cylinder that is provided with helicla flute and straight slot to realize geing out of the way of pivoted arm, increased the space, product can take out from mould smoothly.Adopt guide pin bushing and guide pillar to match, guarantee that the relative position of product is accurate; And the interstice coverage of guide pillars and bushes is the 0.005-0.1 millimeter, guaranteed repetitive positioning accuracy; Simultaneously, also guaranteed the gap of drift and die, thus guaranteed punching press product precisely.Also have a nut in the dowel hole, be convenient to change guide pin bushing.Adopt nitrogen spring to substitute general spring; Have long service life, advantage such as backhaul power is big, the common backhaul power that nitrogen spring produced is equivalent to the backhaul power that several spring produces; So adopt nitrogen spring to make the mould design compact more, can more save the space.

The specific embodiment
Like Fig. 1, shown in 2 or 3; The utility model provides a kind of formula wedge that gets out of the way, and comprises that the patrix of flexible connection drives voussoir 1 and slide block 2, and slide block 2 one ends are connected with nitrogen spring 8; Turning cylinder 3 passes casing 5 and is connected with the other end of slide block 2; The other end of turning cylinder 3 is connected with pivoted arm 4, and casing 5 is provided with die 7, and pivoted arm 4 is provided with drift 6 and fixed head 11; Said turning cylinder 3 is provided with helicla flute and straight slot.
The contact-making surface that patrix drives voussoir 1 and slide block 2 is the inclined-plane.
The rotational angle range of turning cylinder 3 is 0-90 degree.
Patrix drives voussoir 1 and is provided with a hook 9, is located at hook groove 10 on the slide block 2 accordingly.
Also has a nut in guide pin bushing 12 holes.
The interstice coverage of guide pillar 13 and guide pin bushing 12 is 0.005-0.1 millimeters.
The course of work of this instance: punch press acts on patrix and drives voussoir 1; Thereby patrix drives voussoir 1 and moves downward; This moment is because patrix drives the contact-making surface of voussoir 1 and slide block 2 is the inclined-plane, and the power of vertical direction is converted into the power of horizontal direction, comes driving sliding block 2 to move backward.At this moment, slide block 2 pulling turning cylinders 3 move backward, and the mid portion of turning cylinder 3 has helicla flute; Having guaranteed that turning cylinder 3 revolves when moving backward turn 90 degrees; After treating that turning cylinder 3 is accomplished 90 degree rotations, the helicla flute on the turning cylinder 3 becomes straight slot, and this moment, slide block continued motion backward; Slide block 2 pulling turning cylinders 3 continue straight motion; In the guide pin bushing 12 that two guide pillars on the pivoted arm 4 13 insert on the casing 5 simultaneously, so just guarantee the positional precision of the fixed head 11 on the pivoted arm 4, guaranteed the gap of drift 6 and die 7.
The backhaul process: patrix drives voussoir 1 and moves upward, and slide block travels forward under the promotion of nitrogen spring 8 for 2 this moments.In this process, if slide block 2 is stuck, patrix drive voussoir 1 can hook hook 9 on the slide block 2 hook groove 10, guarantee that with this slide block 2 can travel forward normally.Drift 6 breaks away from die 7, is that guide pillar 13 breaks away from guide pin bushing 12 then.Then, slide block 2 drives turning cylinders 3 and continues previous motion, and when treating that straight slot on the turning cylinder 3 becomes helicla flute, turning cylinder 3 has been accomplished whole backhaul process together with 4 straight motions of pivoted arm.At this moment, whole pivoted arm 4 has getd out of the way with fixed head 11, has increased the space, and product just can not have from mould, taking out of interference smoothly.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
