[0052] like Figure 2 As shown, the upper surface of the lower die base 1 has a contoured sleeve portion 3, and the contoured sleeve portion 3 is used to sleeve a metal square frame profile with a shrink R angle.

[0053] The external molding extrusion modules include an external molding extrusion block 6 and a first driving member; the external molding extrusion block 6 is slidably arranged on the lower die base 1, and the head of the external molding extrusion block 6 is adapted to the R corner of the outer wall of the metal square frame; the first driving member is used to drive the external molding extrusion block 6 to slide on the lower die base 1 toward the R corner of the outer wall of the metal square frame and extrude the R corner of the outer wall of the metal square frame.

[0054] In this embodiment, the first driving member includes an external driving block 4 and an external sliding block 5; the external driving block 4 is disposed on an external vertical lifting device (the vertical lifting device is not shown in the figure);

[0055] The external slide block 5 is vertically slidably disposed on the lower die base 1 and is located directly below the external driving block 4;

[0056] The upper part of the side surface of the external sliding block 5 facing the outer wall R angle of the corresponding metal frame profile has a first inclined surface 7;

[0057] The external molding extrusion block 6 is horizontally slidably arranged on the lower die base 1;

[0058] The upper part of the side surface of the external molding extrusion block 6 facing the external sliding block 5 has a second inclined surface 8 , and the second inclined surface 8 is adapted to the first inclined surface 7 .

[0059] The internal forming extrusion module comprises an internal forming extrusion block 10 and a second driving member;

[0060] The internal forming extrusion block 10 is slidably arranged on the lower die base 1, and the head of the internal forming extrusion block 10 is adapted to the R angle of the inner wall of the metal square frame;

[0061] The second driving member is used to drive the internal molding extrusion block 10 to slide on the lower die base 1 toward the inner wall R corner of the metal square frame and to extrude the inner wall R corner of the metal square frame.

[0062] In this embodiment, if Figure 4 As shown, the second driving member includes an internal driving block 9; the internal driving block 9 is arranged on an external vertical lifting device (not shown in the figure); a placement groove 11 is provided on the lower die base 1 at the position of the inner wall R angle corresponding to the metal square frame profile, and the placement groove 11 is used to place the corresponding internal forming extrusion block 10, and a first elastic reset member 12 is vertically provided at the bottom of the placement groove 11; the internal forming extrusion block 10 is located in the placement groove 11 and is located directly below the corresponding internal driving block 9, and the head of the internal forming extrusion block 10 is always facing the inner wall R angle of the corresponding metal square frame profile; the tail of the internal forming extrusion block 10 has a dovetail inclined slider 13 inclined upward, as shown in FIG. Figure 3As shown, the placement groove 11 has a matching dovetail inclined slide groove 14 for the position of the dovetail inclined slide block 13, and the dovetail inclined slide block is slidably arranged on the dovetail inclined slide groove 14. In this arrangement, the internal driving block 9 moves downward, pushing the internal forming extrusion block 10 to move downward. Since the dovetail inclined slide block 13 is slidably arranged on the dovetail inclined slide groove 14, the internal forming extrusion block 10 moves downward and also moves inward, thereby reducing the R angle of the inner wall of the corresponding metal square frame profile.

[0063] In this embodiment, the lower die base is provided with a second elastic reset member 15 and a third elastic reset member 16; the second elastic reset member 15 is used to drive the external slider 5 to reset; the third elastic reset member 16 is used to drive the external molding extrusion block 6 to reset. With such a configuration, after the external molding extrusion module shrinks the R angle of the outer wall of the metal frame profile, the external driving block 4 rises with the vertical lifting device, and then the compressed second elastic reset member 15 drives the external slider 5 to move vertically upward to reset, and the third elastic reset member 16 drives the external molding extrusion block 6 to move horizontally in the horizontal direction to restore to the initial position.

[0064] In this embodiment, the novel metal square frame profile R-angle forming parts assembly device further includes a lateral extrusion positioning module, and the lateral extrusion positioning module includes a lateral pressing slider 18 and a third driving member;

[0067] Furthermore, in this embodiment, if Figure 1 and Figure 5 As shown, the third driving member includes a lateral inclined slider insert 17 and a plurality of inclined sliding push blocks 19; the lateral inclined slider insert 17 is arranged on an external vertical lifting device (not shown in the figure), and the lateral inclined slider insert 17 has a third inclined surface 20 at the bottom of the side facing the contoured sleeve portion 3; a plurality of inclined sliding push blocks 19 are fixed on the side of the lateral material pressing slider 18 facing the lateral inclined slider insert 17, and each of the inclined sliding push blocks 19 has a fourth inclined surface 21, and the fourth inclined surface 21 is adapted to the third inclined surface 20. With such an arrangement, when the external vertical lifting device descends, the lateral inclined slider insert 17 also descends vertically, and the third inclined surface 20 cooperates with the inclined sliding push blocks 19, thereby pushing the lateral material pressing slider 18 to move horizontally inward, close to the outer wall of the sleeved metal frame profile, and effectively positioning it.

[0068] Furthermore, if Figure 6 As shown, a fourth elastic reset member 22 is provided on the lateral pressing slider 18 along its sliding direction to facilitate its reset.

[0070] In this embodiment, a metal square frame profile R-angle forming parts assembly device also includes a pressing plate 2, which covers the contour sleeve portion 3 of the lower die base 1 to limit the metal square frame profile in the vertical direction.

[0071] In this embodiment, if Figure 1 As shown, the number of the external forming extrusion modules, the number of the internal forming extrusion modules and the number of the lateral extrusion positioning modules are all four; the four external forming extrusion modules correspond to the outer wall R angle of the metal frame profile respectively; the four internal forming extrusion modules correspond to the inner wall R angle of the metal frame profile respectively; the four lateral extrusion positioning modules correspond to the four outer side surfaces of the metal frame profile sleeved on the profiling sleeve portion respectively; with such an arrangement, when the above-mentioned combined device is used, the metal frame profile to be shrunk in R angle is first sleeved on the profiling sleeve portion 3, the pressing plate 2 is covered, the external lifting device is started, the four lateral extrusion positioning modules are started, and the metal frame profile is sleeved on the profiling sleeve portion 3. The side of the material is positioned, and the external driving blocks on the four external forming and extrusion modules move vertically downward to push the external slider 5 to move downward. Since the first inclined surface 7 and the second inclined surface 8 are adapted to each other, the external forming and extrusion block 6 moves inward to reduce the R angle of the outer wall of the corresponding metal square frame profile; at the same time, the internal driving block 9 moves downward to push the internal forming and extrusion block 10 to move downward. Since the dovetail inclined slider 13 is slidably set on the dovetail inclined slide groove 14, the internal forming and extrusion block 10 moves downward and also moves inward to reduce the R angle of the inner wall of the corresponding metal square frame profile, and the R angle reduction operation of the metal square frame profile can be completed at one time.
