Description

Technical Field

[0001] This utility model relates to the field of bending dies, and in particular to a die for bending and forming Z-shaped sheet metal. Background Technology

[0002] Bending dies are tools used to assist in bending sheet metal into shape. Different dies are composed of different bending parts. Existing bending machines equipped with dies first fix the dies on the worktable, the bending blade is fixedly connected to the stamping assembly, the sheet metal is placed on the dies, and the stamping assembly pushes the bending blade to bend the sheet metal inside the dies, changing the shape of the sheet metal.

[0003] Among them, Z-shaped and double-bent products require bending the sheet twice to complete the production. However, the distance between the two bends of the sheet cannot be too close. When bending one bend, the mold will squeeze the other bend, which is inconvenient for workers and limits the size specifications of the two bends of the product. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for bending and forming Z-shaped sheet metal, which can complete the bending production of two bends in a single bending process.

[0005] The technical solution adopted by the Z-shaped sheet metal bending mold disclosed in this utility model is as follows:

[0006] The device includes an upper mold, a lower mold, and a connecting seat. The upper mold has a first mounting area containing an upper bending blade. A first adjusting member is connected to the upper mold and is connected to the upper bending blade. A first gap exists between the first mounting area and the upper bending blade. The lower mold has a second mounting area containing a lower bending blade. A second adjusting member is connected to the lower mold and is connected to the lower bending blade. A second gap exists between the second mounting area and the lower bending blade. Both the upper and lower bending blades have inclined surfaces. The upper mold is positioned above the lower mold, the upper bending blade is above the second gap, and the lower bending blade is below the first gap. The connecting seat has a third mounting area containing a third adjusting member. The third adjusting member is connected to the lower mold, and a third gap exists between the third mounting area and the lower mold.

[0007] As a preferred embodiment, it also includes two flipping plates. Both the upper and lower molds are provided with arc grooves, and the flipping plates are provided with arc surfaces. The arc surfaces of the two flipping plates slide in contact with the two arc grooves respectively. Tension springs are connected to the flipping plates, and the tension springs of the two flipping plates are connected to the upper mold and the lower mold respectively. The two flipping plates are close to the two inclined surfaces respectively.

[0008] As a preferred embodiment, a first connecting post is embedded in both the upper and lower molds, and a first slot is formed on both the upper and lower molds. The first connecting post passes through the first slot. A second connecting post is embedded in the flip plate, and a second slot is formed on the flip plate. The second connecting post passes through the second slot. The first slot and the second slot are connected. The tension spring is placed in the first slot and the second slot, and both ends of the tension spring are connected to the first connecting post and the second connecting post, respectively.

[0009] As a preferred embodiment, both the upper and lower molds are provided with flat surfaces, the flat surfaces being close to the edge of the arc groove, and the outer side of the flipping plate extending with a limiting edge, the limiting edge touching the flat surface.

[0010] As a preferred embodiment, multiple gaskets are placed in the first gap, the second gap, and the third gap, and the first adjustment member, the second adjustment member, and the third adjustment member all penetrate the adjacent gaskets.

[0011] The beneficial effects of the Z-shaped sheet metal bending mold disclosed in this utility model are:

[0012] The upper die is connected to the stamping assembly of the external bending machine. The connecting seat is installed on the worktable of the external bending machine. The sheet metal is placed between the upper die and the lower die. The stamping assembly of the external bending machine pushes the upper die down. The upper bending cutter pushes the sheet metal into the second gap, and the lower bending cutter pushes the sheet metal into the first gap, so that both the upper and lower bending cutters stamp out two bends on the sheet metal. At the same time, the upper die pushes the sheet metal to continuously bend and make the sheet metal conform to the inclined surface of the lower bending cutter, and the lower die pushes the sheet metal to continuously bend and make the sheet metal conform to the inclined surface of the upper bending cutter, so as to complete the processing of the sheet metal into a Z-shape or two bends in a single stamping.

[0013] By rotating the first, second, and third adjusting components, the widths of the first, second, and third gaps can be adjusted, allowing the upper and lower dies to bend the sheet metal into two bends of different sizes and specifications, and also allowing the upper and lower dies to adapt to sheet metal of different thicknesses.

[0022] This utility model discloses a mold for bending and forming Z-shaped sheet metal, including an upper mold 1, a lower mold 2, two flipping plates 4, and a connecting seat 3.

[0023] The upper mold 1 has a first installation area, and a first adjusting member 111 is connected to the upper mold 1. In this embodiment, two first adjusting members 111 are preferred, and the first adjusting member 111 is a bolt.

By rotating the first adjusting member 111, the upper bending blade 12 is driven to slide in the first installation area, thereby adjusting the width of the first gap.

[0025] The top of the upper die 1 is detachably connected to the stamping assembly of the external bending machine.

[0026] Please refer to Figure 1 , Figure 3 and Figure 4 .

[0027] The lower mold 2 has a second mounting area, and a second adjusting member 211 is connected to the lower mold 2.

[0028] Furthermore, a downward bending blade 22 is provided in the second installation area. The downward bending blade 22 slides in contact with the inner wall of the second installation area. The second adjusting member 211 is connected to the downward bending blade 22. A second gap is provided between the second installation area and the downward bending blade 22. By rotating the second adjusting member 211, the downward bending blade 22 is driven to slide in the second installation area, thereby adjusting the width of the second gap.

[0029] The connecting seat 3 has a third mounting area, and a third adjusting member 311 is connected to the connecting seat 3. In this embodiment, two third adjusting members 311 are preferred, and the third adjusting member 311 is a bolt. The third adjusting member 311 passes through the lower mold 2 and enters the third mounting area.

[0030] The bottom of the lower mold 2 slides in contact with the inner wall of the third installation area. The third adjusting component 311 is connected to the lower mold 2. There is a third gap between the third installation area and the lower mold 2. By rotating the third adjusting component 311, the lower mold 2 is moved to slide in the third installation area, and the width of the third gap is adjusted.

[0031] The bottom of the connecting seat 3 is detachably connected to the worktable of the external bending machine. The upper mold 1 is placed above the lower mold 2. The upper bending blade 12 and the lower bending blade 22 are provided with inclined surfaces 121, so that the two inclined surfaces 121 form blades on the upper bending blade 12 and the lower bending blade 22 respectively. The inclined surface 121 of the upper bending blade 12 is far away from the first gap, and the inclined surface 121 of the lower bending blade 22 is far away from the second gap. The upper bending blade 12 is located above the second gap, and the lower bending blade 22 is located below the first gap.

[0032] Please refer to Figure 2 , Figure 5 and Figure 6 .

[0033] Both the upper mold 1 and the lower mold 2 are provided with arc grooves 13, which are close to the first installation area and the second installation area respectively. Both the upper mold 1 and the lower mold 2 are provided with flat surfaces, which are close to the edge of the arc grooves 13. Both the upper mold 1 and the lower mold 2 are embedded with first connecting posts 14. Both the upper mold 1 and the lower mold 2 are provided with first slots 15. In this embodiment, it is preferred that there are two first slots 15 on both the upper mold 1 and the lower mold 2, and the first connecting posts 14 pass through the first slots 15.

[0034] The flip plate 4 has a contact surface, an arc surface 41, a limiting edge extending from the outer side of the flip plate 4, a second connecting post 42 embedded in the flip plate 4, and a second slot 43. In this embodiment, it is preferred that there are two second slots 43 on each flip plate 4, the second connecting post 42 passes through the second slot 43, and the second connecting post 42 is close to the limiting edge.

[0035] The arc surfaces 41 of the two flip plates 4 slide in contact with the arc grooves 13 of the upper mold 1 and the lower mold 2, respectively. The first groove 15 is connected to the second groove 43. Tension springs 44 are connected to the flip plates 4. In this embodiment, four tension springs 44 are preferred. The tension springs 44 are placed in the first groove 15 and the second groove 43. The two ends of the tension springs 44 are connected to the first connecting post 14 and the second connecting post 42, respectively. The four tension springs 44 pull the two flip plates 4 to slide and rotate on the upper mold 1 and the lower mold 2, respectively, and the limiting edge touches the plane. The plane and the contact surface are parallel to each other. The plane limits the rotation angle of the flip plates 4 in the arc groove 13. The two flip plates 4 are close to the two inclined surfaces 121, respectively.

[0036] Multiple shims 5 are placed in the first gap, the second gap, and the third gap. The first adjusting member 111, the second adjusting member 211, and the third adjusting member 311 all penetrate the adjacent shims 5. By removing the first adjusting member 111, the second adjusting member 211, and the third adjusting member 311, increasing or decreasing the number of shims 5 and placing them in the first gap, the second gap, and the third gap, and then reinstalling the first adjusting member 111, the second adjusting member 211, and the third adjusting member 311, the width of the first gap, the second gap, and the third gap can be adjusted.

[0037] Please refer to Figures 1-6 .

[0038] During processing:

[0039] The sheet metal 6 is placed between the upper mold 1 and the lower mold 2, with the two bends of the sheet metal 6 aligned with the first gap and the second gap. The stamping assembly of the external bending machine pushes the upper mold 1 down, and the blades of the upper bending blade 12 and the lower bending blade 22 push the two bends of the sheet metal 6 into the first gap and the second gap, respectively, so that the upper bending blade 12 and the lower bending blade 22 stamp out two bends on the sheet metal 6. At the same time, the contact surfaces of the two flipping plates 4 touch the sheet metal 6, the flipping plates 4 of the upper mold 1 push the sheet metal 6 to continue bending and make the sheet metal 6 fit against the inclined surface 121 of the lower bending blade 22, and the flipping plates 4 of the lower mold 2 push the sheet metal 6 to continue bending and make the sheet metal 6 fit against the inclined surface 121 of the lower bending blade 22, thus completing the bending of the sheet metal 6.

[0040] When the flipping plate 4 pushes the sheet 6 to bend, the sheet 6 pushes the arc surfaces 41 of the two flipping plates 4 to slide in the arc grooves 13 that contact them, allowing the two flipping plates 4 to rotate at a certain angle on the upper mold 1 and the lower mold 2 respectively. This transforms the moving friction between the sheet 6 and the upper mold 1 and the lower mold 2 during bending into the sliding of the two flipping plates 4 on the upper mold 1 and the lower mold 2 respectively, greatly reducing the friction amplitude between the sheet 6 and the flipping plates 4 during bending. This avoids friction between the contact plate and the sheet 6, preventing scratches from being left on the sheet 6 and reducing the subsequent sanding process of the sheet 6. After the bending is completed, the stamping component of the external bending machine pulls the upper mold 1 to rise, and the worker removes the bent sheet 6. The four tension springs 44 pull the two flipping plates 4 to slide and rotate back on the upper mold 1 and the lower mold 2 respectively, so that the worker only needs to put the sheet 6 to be processed again to perform bending processing, which greatly improves the processing efficiency of the upper mold 1 and the lower mold 2.

[0041] By changing the number of shims 5, the widths of the first gap, the second gap, and the third gap are adjusted, thereby changing the distance between the two bends after the plate 6 is bent; by replacing the upper bending blade 12 with a larger or smaller angle on the inclined plane 121, and replacing the lower bending blade 22 with a larger or smaller angle on the inclined plane 121, the angles of the two bends after the plate 6 is bent are changed.

[0042] This utility model provides a die for bending Z-shaped sheet metal. The upper die is connected to the stamping assembly of an external bending machine. The connecting seat is installed on the worktable of the external bending machine. The sheet metal is placed between the upper die and the lower die. The stamping assembly of the external bending machine pushes the upper die down. The upper bending cutter pushes the sheet metal into the second gap, and the lower bending cutter pushes the sheet metal into the first gap, so that both the upper and lower bending cutters stamp out two bends on the sheet metal. At the same time, the upper die pushes the sheet metal to continuously bend and make the sheet metal conform to the inclined surface of the lower bending cutter, and the lower die pushes the sheet metal to continuously bend and make the sheet metal conform to the inclined surface of the upper bending cutter, so as to complete the processing of Z-shaped or two bends of the sheet metal in a single stamping.

[0043] By rotating the first, second, and third adjusting components, the widths of the first, second, and third gaps can be adjusted, allowing the upper and lower dies to bend the sheet metal into two bends of different sizes and specifications, and also allowing the upper and lower dies to adapt to sheet metal of different thicknesses.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
