Abstract

The utility model discloses a rotary crease-free plate bending female die, which comprises a male die and a bending female die matrix, wherein the bending female die matrix comprises a bending groove, a spring, rotary sliding blocks and arc grooves matched with the rotary sliding blocks; the rotary sliding blocks are arranged in the arc grooves on two sides of the bending groove; one end of the spring is connected with a limit component outside the rotary sliding blocks, and the other end of the spring is connected with the bending female die matrix; and the top surfaces of the rotary sliding blocks have plane structures, and the bottom surfaces of the rotary sliding blocks have arc structures. The rotary combined bending female die has a simple and compact structure, the interchangeability of key components of the female die is enhanced, and the processing cost is reduced; the rotary sliding blocks are simultaneously subjected to acting forces supplied by a plate and the spring during bending, so the plate is not in a fulcrum stress state, the friction between the plate and the rotary sliding blocks is reduced, the scratch of the bent outer lateral surface of the plate is avoided, and impressions and creases at the bent part of the plate in the prior art are effectively overcome.

Description

A kind of rotary no folding line plate bending die
Technical field
The utility model relates to Bending Mould, specifically is meant a kind of rotary no folding line plate bending die.
Background technology
Bending technique uses extensively, is one required important procedures of series of products shaping such as cabinet, rack, door and window.But after common bender was shaped, there were a large amount of impressions, folding line etc. in goods institute bending position, makes product can not satisfy the surface quality requirement.Existing Bending Mould generally is all-in-one-piece, and mould structure is fixed.During such structure mold bending,, often make goods have scratch at the bending lateral surface because of goods and folded block are relative sliding frictions.And the fillet of die is more little, abrades serious more.
The utility model content
The purpose of this utility model is to overcome weak point of the prior art, and a kind of rotary no folding line plate bending die is provided, and compared with prior art, reduces the friction between plate and the die, has avoided impression, the folding line phenomenon of the bending part of plate effectively.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rotary no folding line plate bending die; comprise punch, bending die matrix; it is characterized in that: the deep-slotted chip breaker that also comprises bending groove, spring, rotary slider on the described bending die matrix, matches with rotary slider; described rotary slider is arranged in the deep-slotted chip breaker of bending groove both sides; one end of described spring is connected with the limiting component in the rotary slider outside, and the other end is connected with bending die matrix.
The end face of described rotary slider is a planar structure, and the bottom surface is an arcuate structure.The arcwall face of rotary slider is positioned in the deep-slotted chip breaker.
In BENDING PROCESS to the plate bending, two rotary sliders rotate along with the descending of plate bending punch, coupled spring gives two rotary sliders a pulling force opposite with direction of rotation because of being in extended state simultaneously, and is crooked under the fulcrum stress thereby BENDING PROCESS does not belong to.
The relative prior art of the utility model has following advantage and beneficial effect:
The utility model has adopted rotatable combined type bending die, and is simple and compact for structure, and the interchangeability of die critical component strengthens, and has reduced processing cost; Rotary slider is subjected to the active force that plate and spring give simultaneously in the bending process, make plate not be in the fulcrum stress, reduced the friction between plate and the rotary slider, avoid the scratch of plate bending lateral surface, overcome the impression of the bending part of plate, folding line phenomenon in the prior art effectively.
Description of drawings
Structural representation when Fig. 1 is a bending die closure state of the present utility model;
Structural representation when Fig. 2 outwards winding state for bending die of the present utility model.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1; rotary no folding line plate bending die of the present utility model; comprise punch (not shown), bending die matrix 1; the deep-slotted chip breaker 1-2 that also comprises bending groove 1-1, spring 2, rotary slider 3 on the described bending die matrix 1, matches with rotary slider 3; described rotary slider 3 is arranged at the interior 1-2 of deep-slotted chip breaker of bending groove 1-1 both sides; rotary slider 3 can rotate with respect to deep-slotted chip breaker 1-2; one end of described spring 2 is connected with the limiting component 3-1 in rotary slider 3 outsides, and the other end of spring 2 is connected with bending die matrix 1.
As can be seen from Figure 1, the end face of rotary slider 3 is a planar structure, and the bottom surface is an arcuate structure.During rotary slider 3 closure states (end face of rotary slider 3 does not dock with bending groove 1-1); under the lower pulling force effect of spring 2; the platform 1-3 of the limiting component 3-1 of rotary slider 3 and die matrix 1 both sides offsets, and it is level that rotary slider 3 keeps upper surface.
As can be seen from Figure 2, rotary slider 3 is in the state of outwarding winding, i.e. bending duty (at this moment, the end face of rotary slider 3 docks with bending groove 1-1).Rotary slider 3 descending and that the certain angle scope takes place is (relevant with the bending angle, be generally 90 the degree) rotatablely move, spring 2 also is in extended state simultaneously, rotary slider 3 is subjected to one and direction of rotation opposing pulling force, this moment, plate was subjected to the downforce of bending punch (not shown) and active force that the rotary slider 3 that causes because of spring 2 pulling force gives simultaneously, thereby make the plate (not shown) not be in a kind of fulcrum stress, can reduce the friction between rotary slider 2 and the plate like this, thus the surface quality that reaches the slotting wound that reduced 2 pairs of plates of rotary slider and impression and improve the bending finished product.
The foregoing description is the utility model preferred implementation; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
