[0041] As described in the background section of this application, before using a rectangular metal sheet, the four top corners of the sheet must be cut off, and then the four sides are folded 90 degrees using a folding device for later use.

[0042] The inventors of this application have discovered that the current process of cutting corners on metal sheets is slow, inefficient, and wastes time and labor costs.

[0043] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

[0044] Figure 1 This is a schematic diagram of the panel chamfering mold in an embodiment of this utility model. Figure 2 This is a schematic diagram of the lower mold in an embodiment of the present utility model. Figure 3 As described in the embodiments of this utility model Figure 2 A magnified view of a portion of the image. Figure 4 This is a schematic diagram of the upper mold in an embodiment of the present utility model. Figure 5 This is a schematic diagram showing the placement of the panel in an embodiment of this utility model.

[0045] like Figures 1 to 5 As shown, the panel corner cutting mold of this embodiment includes: a lower mold 1 and an upper mold 2.

[0046] The lower mold 1 includes: a lower template 11, a lower module 12, and a panel positioning block 13.

[0047] The lower module 12 is a square block and is set on the top surface of the lower template 11. A notch 121 is provided in the middle of one side wall of the lower module 12. The notch 121 of the lower module 12 is V-shaped and the V-shaped notch of the lower module 12 is right-angled with an opening angle of 90°.

[0048] There are two panel positioning blocks 13. The two panel positioning blocks 13 are set on the lower template 11, located on the left and right sides of the lower module 12 respectively, and the height of the panel positioning blocks 13 is greater than the height of the lower module 12.

[0049] The two panel positioning blocks 13 are arranged in a V-shape perpendicular to each other, and the two panel positioning blocks 13 are symmetrically arranged with respect to the center line of the notch 121 of the lower module 12.

[0050] The upper mold 2 includes: upper template 21 and upper module 22.

[0051] The upper module 21 is also square-shaped and is set on the bottom surface of the upper template 21. The upper mold 2 has a boss 23 at the bottom of the upper module 22. The boss 23 of the upper module 22 has a V-shaped protrusion 231, and the V-shaped protrusion of the upper module 22 is adapted to the V-shaped notch of the lower module 12.

[0052] In this embodiment, the lower die 1 is fixedly mounted on the lower frame of the punch press, and the upper die 2 is mounted on the upper frame of the punch press and connected to the drive mechanism (hydraulic mechanism) of the punch press. The drive mechanism drives the upper die 2 to rise and fall.

[0053] like Figure 5 As shown, the operator places the panel 400 to be cut on the lower module 12 of the lower mold 1, so that the two right-angled sides of the panel 400 abut against the panel positioning blocks 13 on both sides, so that the panel 400 is positioned on the lower mold 1. At this time, the top corner of the panel 400 to be cut is located at the notch 121 of the lower module 12.

[0054] When the upper mold 2 moves downward, the V-shaped protrusion of the upper module 22 moves downward along the V-shaped notch of the lower module 12. The upper module 22 and the lower module 12 cooperate to cut off the top corner of the panel 400, thus completing the corner cutting operation of the panel.

[0055] In this embodiment, the V-shaped notch of the lower module 12 is right-angled, with an opening angle of 90°, forming a 90° right-angle cut on the panel. As needed, the opening angle of the V-shaped notch can be any angle, thus forming a cut on the panel at any angle to meet specific design and usage requirements.

[0056] As can be seen from the above, the panel corner-cutting die of this embodiment, by setting a lower die and an upper die, includes: a lower template, a lower module, and panel positioning blocks. The lower module is set on the lower template and has a V-shaped notch. Two panel positioning blocks are vertically set on the lower template, located on both sides of the lower module. The upper die includes: an upper template and an upper module. The upper module is set on the upper template and has a boss with protrusions that match the notch. In this embodiment, the lower die and the upper module are set on the frame of the punch press. The upper die is connected to the drive mechanism (hydraulic mechanism) of the punch press, and the drive mechanism drives the upper die to rise and fall. The panel to be corner-cut is placed on the lower module of the lower die, so that the two right-angled edges of the panel abut against the panel positioning blocks on both sides. Then, the drive mechanism drives the upper die to move downward, and the V-shaped protrusions of the upper module move downward along the V-shaped notch of the lower module, cutting off the top corner of the panel and completing the panel corner-cutting operation. Using a panel corner cutting die on a punch press to cut the corners of panels allows for the cutting of a large number of metal sheets in a short time, greatly saving time and labor costs and significantly improving production efficiency.

[0057] Optionally, in this embodiment, the panel corner cutting mold has two guide posts 14 spaced apart on the top surface of the lower template 11.

[0058] The upper mold 2 has two guide tubes 24 on the bottom surface of the upper template 21. The guide tubes 24 of the upper mold 2 are sleeved on the outside of the guide post 14 of the lower mold 1. When the upper mold 2 is raised and lowered, the guide tubes 24 of the upper mold 2 slide up and down along the guide post 14 of the lower mold 1, so that the chamfering of the panel is more accurate.

[0059] Furthermore, in this embodiment, the guide post 14 of the lower mold 1 of the panel corner cutting mold includes: a fixed post 141, a movable post 142, and a spring 143.

[0060] The fixed column 141 is set on the top surface of the lower template 11, and the movable column 142 is slidably sleeved on the fixed column 141 and located at the top of the fixed column 141.

[0061] Spring 143 is sleeved on fixed column 141. The bottom end of spring 143 abuts against lower template 11, and the top end of spring 143 abuts against movable column 142.

[0062] In this embodiment, when the upper mold descends, the guide sleeve of the upper mold drives the movable column to move downward, and the spring is compressed; when the upper mold rises, the movable column is reset under the action of the spring, and the spring realizes the buffer when the panel is cut at the corner.

[0063] Furthermore, in this embodiment, the panel corner cutting mold has multiple receiving grooves densely arranged on the circumferential sidewall of the movable column 142.

[0064] A ball bearing 144 is provided in the receiving groove of the movable column 142. The ball bearing 144 is rotatably disposed in the receiving groove of the movable column 142. The ball bearing 144 contacts and abuts against the inner wall of the guide sleeve 24 of the upper mold 2, thereby reducing the friction between the guide sleeve 24 and the movable column 142.

[0065] Optionally, in this embodiment, the panel corner cutting mold has a through hole 111 at the notch 121 of the lower module 12 in the lower template 11.

[0066] When the panel is cut at the corner, the scrap material removed falls through the through hole 111 of the lower template 11, which facilitates the collection of the scrap material.

[0067] Optionally, in this embodiment, the panel corner cutting mold has a right-angled L-shaped panel positioning block 13, which includes a horizontal plate 131 and a vertical plate 132.

[0068] The horizontal plate 131 is fixed to the threaded hole of the lower template 11 by bolts, and the height of the vertical plate 132 is greater than the height of the upper module 12. When the panel is cut, the right-angled edge of the panel 400 abuts against the vertical plate 132 of the panel positioning block 13, so that the panel 400 is positioned on the lower mold 1.

[0069] Optionally, in this embodiment, the panel corner cutting mold has threaded holes on the top surface of the lower template 11 and the bottom surface of the upper template 21.

[0070] Both the upper module 22 and the lower module 12 are provided with mounting through holes, so that the upper module 22 and the lower module 12 can be detachably fixed to the upper template 21 and the lower template 11 respectively by fixing bolts.

[0071] In this embodiment, the upper module and the lower module are fixed to the upper template and the lower template respectively by fixing bolts. When cutting panels of different specifications or cutting corners of different sizes, it is only necessary to replace the lower module and the upper module with corresponding notches and protrusions, which improves the compatibility of the corner cutting mold and makes it more convenient to use.

[0072] Furthermore, the panel corner cutting mold in this embodiment also includes: a tendon column 3.

[0073] The reinforcing bar 3 is set on the bottom surface of the upper module 22. When the upper module 2 descends, the reinforcing bar 3 presses down and holds against the panel 400, keeping the panel stable. At the same time, the reinforcing bar 3 can prevent the upper module 22 from contacting the panel 400 and the lower module 12, thus protecting the panel 400 and the lower module 12. In addition, the elasticity of the reinforcing bar 3 can buffer the panel when it is cut at the corner.

[0074] Furthermore, in this embodiment, the panel corner cutting die has a limiting post 211 on the top of the upper template 21. The limiting post 211 of the upper die 2 is used to connect with the limiting hole of the punch drive mechanism, so that the upper die 2 can be quickly limited on the punch drive mechanism, which facilitates the installation and fixing of the upper die.

[0075] In this utility model, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature can mean that the first feature and the second feature are in direct contact, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0076] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
