Specific embodiment
In the following, with reference to attached drawing and specific embodiment, the present invention is described further, it should be noted that not
Under the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
As shown in Figs. 1-2, the mountain-climbing Button Block that the present invention makes includes frame shape adjusting buckle main body A and adjusting buckle accessory B,
In, the outline border length of the frame shape adjusting buckle main body is 53mm, and outer width of frame is 40mm, the inside casing of the frame shape adjusting buckle main body
Length is 39mm, and outer width of frame is 24.7mm；The maximum length length of the adjusting buckle accessory is 50mm, and minimum length is
46mm。
Above-mentioned mountain-climbing Button Block manufacture craft, including:
The step of making adjusting buckle main body and adjusting buckle accessory：Die casting frame shape adjusting buckle main body and tune is respectively adopted
Save snap fit part；
The step of frame shape adjusting buckle bulk deformation：Molding frame shape adjusting buckle main body is put into deforming moulds, makes frame shape
The diagonal of adjusting buckle main body is identical with vertical direction；Using frame hydraulic press, along frame shape adjusting buckle main body diagonal to
It pushes, frame shape adjusting buckle main body is pressed into parallelogram；
The step of being put into adjusting buckle accessory：Adjusting buckle accessory is put into frame shape from the longest diagonal of parallelogram to adjust
In the inside casing for detaining main body；
The step of pushing back original shape：Frame shape adjusting buckle main body is put into correction mold again, makes frame shape adjusting buckle main body most
Long-diagonal is identical with vertical direction；Using frame hydraulic press, it is pressed downward along the longest diagonal of frame shape adjusting buckle main body, it will
The frame shape adjusting buckle main body of parallelogram pushes back original shape to get mountain-climbing Button Block.
Preferably scheme, it is basically identical with the shape before deformation after deforming in order to ensure, in frame shape adjusting buckle main body
The height pushed described in the step of deformation is identical with the height pushed described in the step of pushing back original shape.By test of many times
Verification when depression distance is 4mm, not only can guarantee that adjusting buckle accessory can be smoothly mounted in frame shape adjusting buckle main body, but also can be to the greatest extent
The amplitude of deformation of frame shape adjusting buckle main body is likely to reduced, excessive deformation is avoided to reduce the risk of frame shape adjusting buckle main body intensity.
Specifically, as shown in figure 3, in the step of frame shape adjusting buckle bulk deformation, the deforming moulds are included under first
1 and first upper mold 2 of mould；First time storage tank 11 of the recessed placement frame shape adjusting buckle main body of first lower die；Under first
One is convexly equipped in storage tank for preventing the first limit base 12 of frame shape adjusting buckle body displacements, which is equipped with
With matched first lower arcuate slot 13 of frame shape adjusting buckle the first corner shape of main body；The recessed placement frame shape of first upper mold
Storage tank 21 on the first of adjusting buckle main body；Arc groove in the second corner shape matched first is equipped on first in storage tank
22；First turning is the diagonal of frame shape adjusting buckle main body with the second turning, and the diagonal at the first turning and the second turning is arranged on
In vertical direction；It is correspondingly provided in the left and right sides of first time storage tank and is adjusted for clamp frame shape from horizontal direction respectively
Detain the first left 3 and first right elastic pressuring plate 4 of elastic pressuring plate of main body；In the first left elastic pressuring plate and the first right elastic pressuring plate
Wall shape matches with frame shape adjusting buckle main body outer contour shape；Preferably, the first of this deforming moulds the left elastic pressuring plate and
The height of first right elastic pressuring plate should be less than or equal to the height of first time storage tank.
In the present embodiment, by frame shape adjusting buckle main body tilt 58 °, make the first turning stress point and the second turning by
Force overlaps, at this point, the height of the pushing is equal to the frame cornerwise distance of shape adjusting buckle main body and the first lower arcuate slot and the
The absolute value of the difference of longest distance on one between arc groove, i.e. 4mm.
When the first upper mold is pressed downward, since frame shape adjusting buckle main body deforms upon, the first left elastic pressuring plate and first right side
The left and right sides is mobile respectively for elastic pressuring plate, to adapt to the deformation of frame shape adjusting buckle main body, when the first upper mold presses to fitting first
During lower die, deformed movement is completed.

Upper mold 6；Second time storage tank 51 of the recessed placement frame shape adjusting buckle main body of second lower die；Second time storage tank convex
If there are one for preventing the second limit base 52 of frame shape adjusting buckle body displacements, which is equipped with is adjusted with frame shape
Detain matched second lower arcuate slot 53 of the first corner shape of main body；The recessed placement frame shape adjusting buckle main body of second upper mold
Second on storage tank 61；Arc groove 62 in the second corner shape matched second is equipped on second in storage tank；First turning
It is the diagonal of frame shape adjusting buckle main body with the second turning, the diagonal at the first turning and the second turning is set in vertical direction；
It is correspondingly provided with respectively in the left and right sides of second time storage tank for the of clamp frame shape adjusting buckle main body from horizontal direction
Two left 7 and second right elastic pressuring plates 8 of elastic pressuring plate；The second left elastic pressuring plate and the second right elastic pressuring plate inner wall shape with
Frame shape adjusting buckle main body outer contour shape matches；This correction mold and deforming moulds the difference is that the second left elastic pressuring plate and
The size shape of second right elastic pressuring plate, the height of the especially second left elastic pressuring plate, physical relationship are as follows：Second left elasticity pressure
The height L3 that the height L2+ of storage tank is pushed on the height L1+ second of second time storage tank of height L=of piece；And the second right bullet
Property tabletting height be less than or equal to the height of second time storage tank.
Preferably, it is equipped in the middle part of storage tank on second time storage tank and second and places adjusting buckle accessory
Accessory storage tank 54.
As a preferred option, in order to save the replacement process of mold, i.e., using deforming moulds with correction mold as same
Mold uses, it is only necessary to and the height of left and right elastic piece is adjusted, i.e., the height of right elastic pressuring plate is set as to the height of lower storage tank, it will
The height of height+pushing of storage tank in the height+the second of the lower storage tank of height=the second of second left elastic pressuring plate.In frame shape
In the step of adjusting buckle bulk deformation, this correction mold can be utilized, but the second left elastic pressuring plate need to be removed, push back original shape
In step, the second left elastic pressuring plate is placed into.
The above embodiment is only the preferred embodiment of the present invention, it is impossible to the scope of protection of the invention is limited with this,
The variation and replacement for any unsubstantiality that those skilled in the art is done on the basis of the present invention belong to institute of the present invention
Claimed range.
