Wide thin material buoyant device
The utility model relates to a kind of wide thin material buoyant device, and be particularly useful for width and be greater than 50mm, thickness is less than the buoyant device of the wide thin material of 0.08mm, belongs to Mould Machining field.
As shown in Figure 1-2, the buoyance lift to diel material used in Mould Machining mode traditional at present, generally all adopts the device such as buoyant block 5 or buoyant pin to treat the buoyant operation of stamping material.The method of this local buoyant, can play good effect to the good thick material of the strength of materials.For the thin material that intensity is poor, be especially greater than 50mm to width, the wide thin material that thickness is less than 0.08mm just also exists many problems.Because the thickness of wide thin material is less, intensity is poor, so be difficult to held stationary in the flotation of material 1, very easily occurs that unstable phenomenon fixed by material in follow-up punching press.The punching press when material 1 fixing shakiness, is easy to the damage causing diel, so, not only makes production efficiency decline, also make the frequency of maintenance of mould greatly increase simultaneously, further increase production cost.Meanwhile, owing to only supporting by four points bottom material 1, be easy to be bent downwardly because of gravity so lack at it centre position supported, be also easy to like this produce underproof product in the process of follow-up punching press.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes a kind of wide thin material buoyant device.
The purpose of this utility model, will be achieved by the following technical programs:
A kind of wide thin material buoyant device, comprise the pedestal that inside is provided with spring, and be arranged on the lower bolster above described pedestal, described device also comprises the lower bolster being arranged on described pedestal and described lower bolster centre position; Being provided with the contour screw for controlling buoyant height in described lower bolster, in described lower bolster, being provided with a pair buoyant guide plate for fixing material to be processed; Described buoyant guide plate is connected with described spring by described contour screw.
Preferably, each described buoyant guide plate offers the material groove supported for material folding, described material channel opening is oppositely arranged, and the gap between described material groove is suitable with the width of product to be held, and the opening diameter of described material groove is suitable with product thickness.
Preferably, described product width to be held is greater than 50mm, and thickness is less than 0.08mm.
The utility model gives prominence to effect: this device is by changing traditional buoyant block into buoyant guide plate, traditional point is supported the face changing both sides into support, greatly improve the stability in wide thin material buoyant process, improve the operability of the follow-up punching press of material, extend the service life of diel further, save the production cost of enterprise.Meanwhile, new buoyant supporting way it also avoid traditional point and supports the material bending caused, and further increases the yields of product, improves the production efficiency of enterprise.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, is easier to understand, grasp to make technical solutions of the utility model.

Detailed description of the invention
As shown in Fig. 3 ~ 4, the utility model discloses a kind of wide thin material buoyant device, consistent with prior art, includes the pedestal 2 that inside is provided with spring 3, and is arranged on the lower bolster 4 above described pedestal 2.
Unlike the prior art, described device also comprises the lower bolster 6 being arranged on described pedestal 2 and described lower bolster 4 centre position, is provided with the contour screw 7 for controlling buoyant height in described lower bolster 6.Described buoyant guide plate 8 is connected with described spring 3 by described contour screw 7, and can by the buoyance lift completed material 1 of spring.
A pair buoyant guide plate 8 for fixing material to be processed is provided with in described lower bolster 4, each described buoyant guide plate 8 is provided with the material groove 9 supported for material folding, described material groove 9 opening is oppositely arranged, spacing between two described material grooves is suitable with material 1 width, material groove 9 opening bore and material 1 thickness are suitable, make material 1 can be freely movable in described material groove 9.
Described in the application, product width to be held is greater than 50mm, and thickness is less than 0.08mm.
Below sketch the course of work of this device: material 1 enters into the material groove 9 of described buoyant guide plate 8, operator selects the height of suitable buoyant guide plate 8 by control spring according to the height of required buoyant.Described spring drives the process of described contour screw 7 and method of operating thereof to be existing technology, does not repeat at this.Contact owing to have employed face between material groove 9 with material 1, wide thin material has all been done in both sides and has been fixed on support accordingly, therefore while carrying out buoyant, material can not produce distortion.
This device is by changing traditional buoyant block into buoyant guide plate, traditional point is supported while changing both sides into and support, greatly improve the stability in wide thin material buoyant process, improve the operability of the follow-up punching press of material, extend the service life of diel further, save the production cost of enterprise.Meanwhile, new buoyant supporting way it also avoid traditional point and supports the material bending caused, and further increases the yields of product, improves the production efficiency of enterprise.
The utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection domain of the present utility model.
