Description
Technical field
The utility model relates to a kind of processing unit (plant)s of construction material more particularly to a kind of food building plate parts-moulding to fill
It sets and uses punch structure.
Background technique
Due to the development of new technology, steel construction is more and more used in building, and with processing technology and people
To design art, aesthetics, multifarious demand, carry out use curve form, especially catering field the more, more for body
Existing characteristic, building structure increasingly individual character, steel sheet component moulding increasingly uses abnormally-structured.In the prior art, for arc
Or curvature of space shape outer wall, at present the outer panel member of unidirectional curvature generally use three-roll bending machine or hydraulic press carry out clod wash at
Shape, and for the outer panel member of complicated three-dimension curved surface, then Cold-forming process is stated in use carries out longitudinal curvature machine-shaping
On the basis of, then processed with the thermal flexure that flame forming plate method carries out lateral curvature.The flame forming plate production efficiency is low, labor
Fatigue resistance is big, it is high to require worker's technical level.
As shown in Figure 1, the multi-point formation apparatus that domestic-developed goes out is made up of the pressure head of numerous adjustment heights has three-dimensional
The mold of curve form is that one kind has feasible method instead of traditional unitary mould pressed sheet component forming.Currently, more
Point forming device usually have up and down two sets pressure head basic body groups, by upper and lower two sets of pressure heads basic body group formation profile surface come
Three-dimension curved surface plate material parts are suppressed, some seaming chuck basic body unit center when compacting in pressure head basic body group is corresponding
Push-down head basic body unit center is on the same axis, i.e., using to pressure mode.
Stringenter for the positioning requirements of plate in this process engineering, current positioning method is to be existed using fixture
The surrounding of plate positions, this requires that plate reserves the edge of certain distance, causes the waste of plate, another, fixture is fixed
The mode of position is more time-consuming, and higher cost.
In the prior art, it is that positioning pin is set on edge formed punch there are also a kind of positioning method, fixture can be saved in this way,
And then avoid the waste of plate.However plate can bend in forming process, due to controlling the location hole at two edges,
Cambered surface is apart from constant upon bending, but minor change occurs for linear distance, and through-hole direction deflects, and leads to positioning pin
It cannot adapt to very well, or be detached from plate, influence processing quality.

Specific embodiment
Below by way of specific implementation case come introduce the utility model implementation and specific effect.
Embodiment 1:
Referring to shown in attached drawing 2-3, the punch structure of the molding machine of the utility model embodiment 1, molding machine are shown
Lower die is only listed, lower die includes one or more groups of formed punches, and every group of formed punch includes the multiple formed punches for being arranged in multiple lines and multiple rows.
Wherein, formed punch includes common formed punch 3 and aligning punch 2, both includes head and main part, wherein the master of the two
The structure in body portion is identical, and removable unload down in head is mounted on other main parts, is illustrated by taking aligning punch 2 as an example below.
As shown in figure 4, aligning punch includes head 21, main part 22 and middle part 23, wherein protrusive board is arranged in head lower end
212, for being rotatablely connected with middle part 23, specifically, through-hole, 23 upper middle position of middle part are provided on protrusive board 212
It is formed fluted, for accommodating the protrusive board 212, is formed on the arm of the groove two sides and be provided with articulated shaft, for being inserted into
(such as articulated shaft is fixed after the arm insertion of groove side) is stated in the hole of protrusive board 212, so that protrusive board 212 drives 21 phase of head
Hinged shaft is rotated.Matching for the side wall of the protrusive board 212 and groove is combined into relatively tight fit, needs certain strength when rotated
Just it is able to achieve.It is highly preferred that additional friction structure can be set, it is highly preferred that the friction structure makes the rotation of protrusive board 212
Gyration there are a limiting value (for example, friction structure be there are an inclined-plane, after reaching the predetermined angular, the inclined-plane
It will rotate stuck)
23 lower end of middle part is formed with insertion section 231, is cylindrical structure, and recess diameter is less than the diameter of top end part.
The top of main part 22 is provided with insertion hole (not shown), is inserted into for insertion section 231, and by main part side wall
Fixation hole 223 in be inserted into fixed pin, block the neck of insertion section 231, fixation of the realization body portion 22 to middle part 23, and in
Between portion 23 can be rotated relative to main part 22.
Preferably mutually engageable first tooth knot is formed in the upper surface of the lower end surface of middle part 23 and main part 21
Structure 232 and the second toothing 224, the toothing include multiple teeth, and each tooth is sector structure, multiple teeth of the toothing
Including two height, preferably adjacent teeth is located at different height, and the of the first toothing 232 of middle part 23 and main part 21
Two toothings 224 can engage again after relative rotation certain angle, and can cooperate in multiple positions, and the quantity of the tooth is more,
The position of the cooperation is also more.After teeth portion is worked good, since adjacent tooth height is different, very big resistance resistance can produce
Only rotation of the middle part 23 relative to main part 22.
When work, the corresponding positioning pin 211 of each location hole can be set according to the curved shape for the plate 1 being pre-designed
Need to rotate direction (due to plate bending typically with respect to horizontal position downward shift, positioning pin 211 turn
The dynamic rotation typically with respect to axis a certain on horizontal plane).Accordingly, calculate in advance different positioning pins 211 rotating shaft direction and
Then angle can set the rotation axis of positioning pin 211 by the way that middle part 23 turns an angle relative to main part 22,
The first teeth portion and the second teeth portion are engaged, protrusive board 212 is then set relative to centre by the selection of friction structure again
The rotation angle in portion 23.
Later, plate is mounted in lower die, starts to process, in process, plate 1 bends, positioning pin 211
Adaptability rotation is carried out in scheduled direction, is suitable for the variation of the distance.In addition, not meeting design for plate 1
It is required that deformation, the engagement of deformation in the horizontal plane, the teeth portion of middle part 23 and main part 22 can carry out opposite prevention, In
The deformation of perpendicular, can be limited by the extreme angles of protrusive board 213 (can certainly be carried out by the frictional force of close contact
Certain limitation).
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
