DETAILED DESCRIPTION

[0038] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0039] The first implementation method:

[0040] The present invention provides a high-safety metal profile processing equipment, please refer to Figure 1 , including an upper mold 1 and a lower mold 3 fixedly connected to the upper end of a base 2, and the upper mold 1 is located directly above the lower mold 3. The processing equipment also includes a plurality of main inclined plates 4, a plurality of auxiliary inclined plates 5, and a horizontal plate 6 for connecting the main inclined plates 4 and the auxiliary inclined plates 5.

[0041] Combination Figure 4 and Figure 5 As shown, the main inclined plate 4 includes a main board body 41, one end face of the main board body 41 is rotatably connected to a pair of main flat plates 42 of different widths, and the other end face of the main board body 41 is rotatably connected to a pair of main flat frames 43 of different widths. The auxiliary inclined plate 5 includes an auxiliary board body 51, one end face of the auxiliary board body 51 is rotatably connected to a pair of auxiliary flat plates 52 of different widths, and the other end face of the auxiliary board body 51 is rotatably connected to a pair of auxiliary flat frames 53 of different widths.

[0042] See also Figure 4 , one end of the main flat frame 43 away from the main plate body 41 and one end of the sub-flat frame 53 away from the sub-plate body 51 are fixedly connected with a pair of rotating shaft seats 8, the main plate 42 and the sub-flat frame 53 are rotatably connected through the rotating shaft seat 8, and the main flat frame 43 and the sub-plate 52 are rotatably connected through the rotating shaft seat 8. In this embodiment, the width of the upper main plate 42 is smaller than the width of the lower main plate 42, the width of the upper main flat frame 43 is larger than the width of the lower main flat frame 43, the width of the upper sub-plate 52 is larger than the width of the lower sub-plate 52, and the width of the upper sub-plate 53 is smaller than the width of the lower sub-plate 53, so that: combined with Figure 3As shown, when the auxiliary inclined plates 5 are connected on both sides of the main inclined plate 4, the main inclined plate 4 and the auxiliary inclined plates 5 on one side can form a V-shaped structure that is wide at the top and narrow at the bottom, and the main inclined plate 4 and the auxiliary inclined plates 5 on the other side can form a V-shaped structure that is narrow at the top and wide at the bottom, so that when multiple main inclined plates 4 and auxiliary inclined plates 5 are connected at intervals, a stable zigzag structure can be formed, which has a stable supporting effect on the metal plate.

[0043] See also Figure 6 The rotating shaft seat 8 includes a fixed plate 81, an inner rod 83 is movably inserted inside the fixed plate 81, and the two ends of the inner rod 83 are respectively fixedly connected with an outer handle 82 and an insertion rod 84, a pair of side ends of the main plate 42 are provided with a main positioning groove 4201, and a pair of side ends of the auxiliary plate 52 are provided with an auxiliary positioning groove 5201, and the main positioning groove 4201 and the auxiliary positioning groove 5201 are matched with the insertion rod 84, the outer diameters of the outer handle 82 and the insertion rod 84 are larger than the outer diameter of the inner rod 83, and the fixed plate 81 is provided with a plurality of outer handles 82 and an insertion rod 84. A rotating hole 8101 is provided, and the inner diameter of the rotating hole 8101 close to the insertion rod 84 is the same as the outer diameter of the insertion rod 84, and the inner diameter of the rotating hole 8101 close to the outer handle 82 is the same as the outer diameter of the inner rod 83. The outer handle 82 is located on the outside of the fixed plate 81. When the outer handle 82 contacts the fixed plate 81, one end of the insertion rod 84 extends to the outside of the fixed plate 81, and the inner wall of the main positioning groove 4201, the inner wall of the secondary positioning groove 5201 and the end of the insertion rod 84 away from the inner rod 83 are all fixedly connected with a magnetic sheet 9.

[0044] When the shaft seat 8 is used to connect the main plate 42 and the auxiliary plate frame 53, or the main plate frame 43 and the auxiliary plate 52, the specific operation is as follows: Figure 7 and Figure 8 Taking the connection between the auxiliary flat plate 52 and the main flat frame 43 as an example, first pull the pair of outer handles 82 toward the outside of the fixed plate 81 to drive the insertion rod 84 to completely enter the rotating hole 8101, then move the auxiliary flat plate 52 to the inside of the main flat frame 43, and align the auxiliary positioning groove 5201 with the rotating hole 8101. Under the magnetic attraction of the magnetic sheet 9, the insertion rod 84 can automatically enter the auxiliary positioning groove 5201 to achieve the connection between the auxiliary flat plate 52 and the main flat frame 43;

[0045] In addition, the main flat frame 43 and the auxiliary flat frame 53 both adopt a U-shaped structure, the width of the main flat plate 42 matches the inner width of the corresponding auxiliary flat frame 53, and the width of the auxiliary flat plate 52 matches the inner width of the corresponding main flat frame 43. By rotating the insertion rod 84 in the rotating hole 8101 and the auxiliary positioning groove 5201, combined with the feature that the main plate body 41 and the auxiliary plate body 51 are at the same distance from the rotating shaft seat 8, the connection angle between the main flat frame 43 and the auxiliary flat plate 52 can be changed, thereby realizing the expansion and folding process between the main inclined plate 4 and the auxiliary inclined plate 5, so that the main inclined plate 4 and the auxiliary inclined plate 5 can be folded and stored when not in use, without the need to disassemble the two (such as Fig.11 and Fig.12 as shown).

[0046] See also Figure 3 The main inclined plate 4 and the auxiliary inclined plate 5 are connected to the cross plate 6 by bolts 7. The cross plate 6 is provided with a cross hole 601. Figure 5 As shown, a pair of side ends of the main plate body 41 are each provided with a main thread groove 4101, and a pair of side ends of the auxiliary plate body 51 are each provided with an auxiliary thread groove 5101. The bolt 7 passes through the transverse hole 601 and is threadedly connected to the inside of one of the main thread groove 4101 or the auxiliary thread groove 5101. The cross plate 6 is pressed against the side ends of the main inclined plate 4 and the auxiliary inclined plate 5 by the bolt 7, so that the cross plate 6 connects multiple main inclined plates 4 and auxiliary inclined plates 5 to form a serrated overall structure, which plays a stabilizing supporting role for the metal plate to be processed.

[0047] See also Fig. 9 The lower mold 3 includes a mold body 31 fixedly connected to the base 2, and a pair of end faces of the mold body 31 are both inclined, and a pair of inclined ends of the mold body 31 are rotatably connected to a pair of side flat frames 32 with different widths, and the end of the side flat frame 32 away from the mold body 31 is also fixedly connected to a pair of rotating shaft seats 8. When in use, the side flat frame 32 and the adjacent main flat plate 42 can be rotatably connected through the rotating shaft seat 8, and the connection steps are the same as the connection steps between the secondary plate 52 and the main flat frame 43. A pair of slots 3101 are opened at a pair of inclined ends of the mold body 31, and one end of the cross plate 6 is inserted into the inside of the slot 3101. The slot 3101 plays a positioning role for the cross plate 6, which is convenient for the subsequent connection of the main inclined plate 4 and the cross plate 6, and the secondary inclined plate 5 and the cross plate 6.

[0048] A high-safety metal profile processing equipment, the use method of which comprises the following steps:

[0049] S1. According to the shape of the metal plate to be processed and the position to be punched, select a suitable number of main inclined plates 4 and auxiliary inclined plates 5 and assemble them on both sides of the lower die 3;

[0050] like Figure 1 and Figure 2 Two cases are shown:

[0051] exist Figure 1 In the embodiment, one end of the metal plate G has a bent portion g. When stamping is required for other parts of the metal plate G and the bent portion g needs to be placed downward, the existing lower die is difficult to adapt to this type of metal plate (such as Fig.13 As shown), therefore, in this application, Figure 1As shown, according to the distance between the position to be punched and the bending portion g, a small number of main inclined plates 4 and auxiliary inclined plates 5 can be selected and assembled on one side of the lower die 3 to leave space for the bending portion g, and then according to the distance between the position to be punched and the other end of the metal plate, a suitable and sufficient number of main inclined plates 4 and auxiliary inclined plates 5 can be selected and assembled on the other side of the lower die 3 to provide sufficient support for the remaining parts of the metal plate, so that the metal plate G can be placed flat and stably;

[0052] exist Figure 2 In the process, when the position to be processed of the metal plate N is close to its edge, similarly, a small number of main inclined plates 4 and auxiliary inclined plates 5 are assembled on one side of the lower mold 3, and a larger number of main inclined plates 4 and auxiliary inclined plates 5 are assembled on the other side of the lower mold 3, so that the present application can adaptively support both sides of the metal plate according to the distance from the position to be processed to the two ends of the metal plate, thereby improving the stability of the placement of the metal plate.

[0053] S2, assembly: multiple main inclined plates 4 and multiple auxiliary inclined plates 5 are arranged at intervals on the upper side of the base 2, and adjacent main flat plates 42 and auxiliary flat frames 53, as well as adjacent main flat frames 43 and auxiliary flat plates 52 are rotatably connected through the rotating shaft seat 8, and adjacent main flat plates 42 and side flat frames 32 are also rotatably connected through the rotating shaft seat 8;

[0054] S3, fixing: according to the structural length of the main inclined plate 4 and the auxiliary inclined plate 5 after assembly, select a transverse plate 6 of appropriate length, insert one end of the transverse plate 6 into the slot 3101, and then prepare a plurality of bolts 7 to connect and fix the main inclined plate 4 and the transverse plate 6 as well as the auxiliary inclined plate 5 and the transverse plate 6;

[0055] S4. Place the metal plate to be processed on the support structure composed of the lower die 3, the main inclined plate 4 and the auxiliary inclined plate 5, start the equipment, move the upper die 1 downward, and squeeze the position to be stamped on the metal plate into the V-shaped groove of the lower die 3 to achieve bending.

[0056] Second implementation method:

[0057] This embodiment adds the following usage method based on the embodiment 1:

[0058] After completing step S2 and before proceeding to step S3, the metal plate to be processed is placed on the support structure composed of the lower die 3, the main inclined plate 4 and the auxiliary inclined plate 5, and the position to be punched is placed in the V-shaped groove of the lower die 3. Then, according to the straightness of the metal plate, it is confirmed whether it is necessary to adjust the connection angle between the main flat frame 43 and the auxiliary flat plate 52, and between the main flat plate 42 and the auxiliary flat frame 53;

[0059] like Fig.10As shown, when there is an arc structure m on the metal plate M and the arc structure m needs to be placed downward, in order to achieve the flat placement of the metal plate M, at this time, the distance between the main inclined plate 4 and the auxiliary inclined plate 5 at the corresponding position can be adjusted according to the position of the arc structure m, so that the main inclined plate 4 and the auxiliary inclined plate 5 on the lower side of the arc structure m are in a V-shaped structure (supplementary explanation: if the main inclined plate 4 and the auxiliary inclined plate 5 on the lower side of the arc structure m are not V-shaped structures at the beginning, then by adjusting the positions of the other main inclined plates 4 and the auxiliary inclined plates 5 on both sides of the arc structure m, the nearest pair of V-shaped main inclined plates 4 and the auxiliary inclined plates 5 can be moved to the lower side of the arc structure m), and the upper main flat frame 43 and the auxiliary flat plate 52 between the two are rotated from a horizontal distribution to a V-shaped angle state, thereby reserving sufficient accommodation space for the arc structure m, so that the arc structure m is not easy to hinder the placement of other parts of the metal plate, and effectively ensure that the metal plate M can be placed flatly and stably on the upper end of the lower mold 3, the main inclined plate 4 and the auxiliary inclined plate 5.

[0060] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
