Description

Technical Field

[0001] This utility model relates to the field of door product processing technology, and in particular to a profile stamping and forming device. Background Technology

[0002] The current processing technology for hollow frame profiles in medical doors is as follows: four profiles are cut at 45° angles, corner holes are punched in each profile, and corners are connected (using corner brackets) to finally assemble a rectangular frame.

[0003] This method requires cutting the profiles sequentially and then connecting them one by one using corner brackets. The process is cumbersome, the production efficiency is low, and at least four corner brackets are required, which significantly increases the production cost. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a profile stamping and forming device. By stamping and cutting a 90-degree non-breaking slit on the profile, the profile is stamped with a 90° notch (without cutting off). After the profile is stamped, it is directly bent 90° to form a frame. There is no need to use the method of first cutting the corner at 45° and then using corner brackets to connect the corners. This greatly improves the processing efficiency of the profile and reduces the processing cost of the profile.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A profile stamping forming apparatus includes an upper stamping die, a lower stamping die, and a driving device, wherein the upper stamping die is provided with a stamping cutter;

[0008] The upper stamping die is connected to the driving device. The driving device is used to drive the upper stamping die and the lower stamping die to close. After the upper stamping die and the lower stamping die are closed, the driving device drives the upper stamping die to make linear motion along the stamping groove direction to cut the profile.

[0009] When the upper and lower stamping dies are closed, there is an anti-cutting gap between the lowest point of the stamping cutter and the bottom surface of the material hole.

[0010] Furthermore, the driving device includes an upper die base, a first hydraulic component, and a second hydraulic component. The stamping upper die is slidably connected to the upper die base.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See Figures 1-8 This utility model provides a technical solution:

[0029] Example:

[0030] like Figures 1-8 As shown, a profile stamping forming device includes an upper stamping die 1, a lower stamping die 2 and a driving device, wherein the upper stamping die 1 is provided with a stamping cutter 3;

[0031] The lower stamping die 2 is provided with a material hole 6 along its length. The cross-section of the material hole 6 is adapted to the cross-section of the profile 4 and the material hole 6 extends through to both ends of the lower stamping die 2. The side of the lower stamping die 2 is provided with a stamping groove 7 adapted to the stamping cutter 3. The stamping groove 7 communicates with the material hole 6. The stamping groove 7 is provided along the width direction of the lower stamping die 2.

[0032] The upper stamping die 1 is connected to the driving device. The driving device is used to drive the upper stamping die 1 and the lower stamping die 2 to close. After the upper stamping die 1 and the lower stamping die 2 are closed, the driving device drives the upper stamping die 1 to make linear motion along the stamping groove 7 to cut the profile 4.

[0033] When the upper stamping die 1 and the lower stamping die 2 are closed, there is an anti-cutting gap between the lowest point of the stamping cutter 3 and the bottom surface of the material hole 6.

[0034] The driving device includes an upper die base 5, a first hydraulic assembly, and a second hydraulic assembly (not shown in the figure). The stamping upper die 1 is slidably connected to the upper die base 5. The upper die base 5 is mounted on the frame via the vertically arranged first hydraulic assembly. The second hydraulic assembly is located on the side of the upper die base 5 and is horizontally arranged. The piston rod of the second hydraulic assembly is connected to the stamping upper die 1. The cylinder of the first hydraulic assembly is fixedly connected to the frame, and the piston rod of the first hydraulic assembly is connected to the top surface of the upper die base 5. When the piston rod of the first hydraulic assembly extends or retracts, it drives the upper die base 5 to move vertically in a straight line. The frame also has four guide rods, and the top surface of the upper die base 5 has an upper die pad, with the four corners of the upper die pad slidably fitted over the four guide rods.

[0035] The upper die base 5 is provided with a sliding groove perpendicular to the length direction of the lower die 2, and the upper die 1 is provided with a slider. The upper die 1 is slidably connected to the upper die base 5 through the slider and the sliding groove.

[0036] like Figure 1 , Figure 4 and Figure 6 As shown, the upper end of the stamping groove 7 is provided with a positioning groove 9, and the upper stamping die 1 is provided with a positioning platform 8 that is adapted to the positioning groove 9. The positioning platform 8 cooperates with the positioning groove 9 to position the upper stamping die 1 and the lower stamping die 2, ensuring their positioning accuracy.

[0037] The frame is fixedly provided with a lower die pad, and the stamping lower die 2 is set on the lower die pad.

[0038] The cross-section of the feed hole 6 is convex.

[0039] The stamping cutter 3 has a triangular prism structure.

[0040] 1. The frame is existing technology, and its specific structure will not be described in detail here; 2. Both the first hydraulic component and the second hydraulic component are hydraulic cylinders; 3. The cross-section of the stamping cutter 3 is an isosceles right triangle.

[0041] Working principle: The end of the profile 4 (one end in the length direction) is inserted into the material hole 6, and the insertion length is adjusted to adjust the cutting position. When the cutting position corresponds vertically with the stamping cutter 3, the first hydraulic component of the drive device drives the upper die base 5 and the upper stamping die 1 to move toward the lower stamping die 2 until the upper stamping die 1 and the lower stamping die 2 are closed.

[0042] When the upper stamping die 1 and the lower stamping die 2 are closed, the lowest point of the stamping cutter 3 is located above the lowest side of the profile 4 due to the existence of the anti-cutting gap.

[0043] After the upper stamping die 1 and the lower stamping die 2 are closed, the second hydraulic component drives the upper stamping die 1 to move linearly along the stamping groove 7 set in the width direction of the lower stamping die 2. At this time, the stamping cutter 3 cuts the profile 4 to form a notch with an angle of 90 degrees. The above action is repeated twice to form three notches. Then, the notches are closed one by one to obtain a rectangular frame. The two ends of the profile 4 can be formed with 45-degree bevels by the stamping device (when stamping the two ends, the excess part is removed manually).

[0044] Finally, fix both ends of profile 4 with an L-shaped corner bracket.

[0045] The stamping forming device of this utility model forms a 90-degree non-breaking slit by stamping and cutting on the profile, and performs a 90° notch (without cutting) stamping process on the profile. After the profile is stamped, it is directly bent 90° to form a frame. There is no need to use the method of first cutting the corner at 45° and then using corner brackets to connect the corners, which greatly improves the processing efficiency of the profile and reduces the processing cost of the profile.
