Detailed description of the invention
Embodiment 1
As in Figure 2-4, present invention is disclosed a kind of folded material pneumatics mould, comprise punching mechanism, ejecting mechanism and resetting-mechanism.Described punching mechanism comprises die and is arranged on the drift 7 below die, and described die comprises interior die 1 and is socketed the outer die 2 be arranged on around interior die 1.Described ejecting mechanism comprises the de-feed ring 3 be socketed on interior die 1, to be sheathed on interior die 1 and the knock-pin 4 be connected with de-feed ring 3 upper end.Described resetting-mechanism comprises the spring 5 be arranged at above knock-pin 4 and the release link 6 be arranged at below knock-pin 4.Described spring 5 and release link 6 are arranged on the same side of knock-pin 4.
Described interior die 1 lower end is a cylindrical structure, and the diameter of described cylindrical structure is equal with the sunk part internal diameter D1 at product 8 center 82.Described outer die 2 is socketed in around interior die, but there is certain interval between the two, and sidewall 81 thickness after described gap length machines with product 8 is equal.The lower edge position of described interior die and outer die is provided with a circle enters mould chamfering 9 for direct product.
Described drift 7 is arranged on the below of interior die 1 and outer die 2, and the head of drift 7 is planar structure, for support product 8.The diameter of described drift is suitable with product outer diameter D 2.
Described drift 7 and die are not in contact with each other under device holding state, and are provided with punching press reserved area between the two, and the bottom thickness after the size of described punching press reserved area completes with Product processing is equal.
Described de-feed ring 3 is a cylindrical structure, is socketed on interior die 1.The circle wall thickness of described de-feed ring 3 is equal with the gap length between interior die 1 with outer die 2.
One end of described knock-pin 4 is provided with a slotted eye, and the upper end of described interior die 1 is placed in described slotted eye, is provided with the release link 6 that can promote the motion of described knock-pin 4 below the other end of described knock-pin 4.
Described spring 5 to be arranged on above knock-pin 4 and to be close to the surface of knock-pin 4, and described spring 5 can carry out longitudinal extension.Release link 6 is provided with below the knock-pin 4 of position set by spring.Described release link 6 is movable structure, and knock-pin 4 can be driven together to move upward when release link 6 moves upward, knock-pin 4 is Compress Spring 5 upwards, and drives retainer circle 3 upwards to reset.
Below sketch the course of work of the present invention and processing method: before pneumatics is shaping, described release link 6 moves upward, thus by described knock-pin 4 upwards jack-up, knock-pin 4 moves upward Compress Spring 5, and knock-pin 4 is with the de-feed ring 3 be automatically connected in below it upwards to complete reset.
When pneumatics is shaping, the product 8 after preorder PROCESS FOR TREATMENT is placed on drift 7, along with moving upward of drift 7, promotes product 8 and enter in the gap that interior die 1 and outer die 2 formed, thus complete the shaping of product 8 sidewall 81.
After pneumatics is shaping, described drift 7 resets downwards, subsequently, release link 6 moves downward, and makes spring 5 expand reset, promotes described knock-pin 4 and moves down, drive described de-feed ring 3 to move downward, and by completing pneumatics shaping product 8 ejection die, complete the de-material of product 8.
The present invention, by adding one stamping procedure after traditional molding procedure, achieves the laminating completely of the product sidewall materials at two layers that traditional machining cannot realize.Meanwhile, because product material is the aluminium of annealed state, this material is very soft and have certain viscosity, and the spring force that therefore this device ejects can't cause deformation of products, thus ensure that the quality of product.
Embodiment 2
As shown in Figure 5, one of the present invention folded material pneumatics mould can also have another preferred embodiment.In the present embodiment, the interior die of mould overlaps 12 by indent mould body 11 and the indent be socketed on described indent cover body 11 and forms, and the outer die of mould is made up of outer die body 21 and the outer recessed circle 22 be socketed on described outer die body 21.Described inside and outside die is dismountable socket joint type structure.Described indent cover 12 arranges reeded cylinder for centre, and the inwall of described indent cover 12 is provided with a circle magnet 10, and described indent is overlapped 12 and can be socketed in layer by layer on indent mould body 11 by described magnet 10.Owing to indent mould body 11 being socketed with several indents cover 12, so the magnet 10 inside adjacent two indents cover 12 adopts the structure be crisscross arranged up and down, avoid all magnet 10 be arranged on same level causes make indent membrane module that unstable phenomenon is set because magnet 10 repels mutually.
The bottom of described outer recessed circle 22 is provided with a bottom surface extended laterally, by described bottom surface arrange can effectively prevent outer die assembly drift 7 upwards punching press time occur because of bottom unbalance stress skew dislocation, further increase the stability of mould, ensure that the quality of processed product.The arranged outside of described outer recessed circle 22 top circle body has the magnet 10 of a circle for connecting equally, and described outer recessed circle 22 can be socketed on outer die body 21 layer by layer by described magnet 10.Identical with the position that magnet in indent membrane module 10 is arranged, the magnet 10 on adjacent two outer recessed circles also adopts the stability be crisscross arranged up and down with Assurance component.
The de-feed ring 3 that described de-feed ring assembly comprises several different-thickness different-diameters forms, and described de-feed ring 3 the spacing size different from outer die according to interior die can carry out corresponding replacement, to meet the de-material operation of different size converted products.And because described indent membrane module has all applied to magnet 10 with outer die assembly and has been connected, in order to avoid therefore the brought impact on Mould Machining, described de-feed ring 3 should adopt can not be carried out manufacture processing by the metal of magnet adsorption, can adopt aluminum alloy materials manufacture in the present embodiment.Material due to this Mould Machining is the aluminium of annealed state, so the magnetic that this mould adopts connects and can't have an impact to the quality of product.
The present embodiment 2 is interior die relatively-stationary in original device and outer die to be improved in the present embodiment with the difference of embodiment 1, interior die is changed into and overlaps 12 by indent mould body 11 and indent and jointly form, outer die is changed into and is jointly made up of with outer recessed circle 22 outer die body 21, and be provided with de-feed ring supporting with it, thus add regulatory function on the basis of original device.In process of production can by regulating the size of the drift 7 upwards Level Change punching press reserved area of punching press, the processing subsequently by selecting the die that overlaps with processed product matching size and de-feed ring to carry out the product to different inner diameters, various outer diameter and different-thickness.Thus add the range of application of this device, improve the practicality of device.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
