Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a precise angle-cutting device for profiles of new energy energy storage boxes. Background Technique

[0003] At present, there are the following several ways to cut double angles of profiles:

[0004] (1) One set of molds cuts double angles, without specifying the profile length, specifying the profile material width, and the cutting angle size can only be fixed for several specifications through a straight rod type quick plug-in positioning, with poor versatility and the need for multiple sets of molds for production, increasing the mold cost and mold change frequency;

[0005] (2) One set of molds cuts single angles, without specifying the profile length, and can be applicable to profiles with different material widths. The cutting angle size can only be fixed for several specifications through a straight rod type quick plug-in positioning. Compared with the first method, the versatility is much stronger, but only one angle can be cut in one stamping, the cutting angle specifications have a narrow coverage range and the production efficiency is low;

[0006] (3) One set of molds cuts 4 angles, specifying the profile length and width, and the cutting angle size is non-adjustable. This method has a high production efficiency, but the products produced are single, increasing the mold cost and mold change frequency.

[0007] Based on this, the utility model proposes a precise angle-cutting device for profiles of new energy energy storage boxes, which can meet the double-angle processing requirements of different materials, material thicknesses, material widths, and cutting angle sizes through the methods of quick replacement positioning and lower die cutting edges. Content of the Utility Model

[0008] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a precise angle-cutting device for profiles of new energy energy storage boxes. By only replacing the positioning component, the end positioning block, and the cutting edge tool head, it can quickly adapt to the angle-cutting processing requirements of different materials, different material thicknesses, different material widths, and different cutting angle sizes, without the need to replace the mold according to the requirements, with a wide application range, low mold input cost, high debugging and production efficiency.

These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model.

[0037] Embodiment 1

[0038] As Figures 1 - 4 、 Figure 8 shown, a precise chamfering device for a new energy energy storage box profile includes an upper die assembly and a lower die assembly, which can open and close relative to each other under the action of an external stamping machine. When the die is opened, it is used to pick and place the stamping product, and when the die is closed, it is used to stamp out the double angles of the profile product 6; the upper die assembly includes an upper template 1, and two trimming punches 11 distributed in a figure-eight shape are arranged on the upper template 1; the lower die assembly includes a lower template 2 parallel to the upper template 1, a relief groove 21 corresponding to the position and quantity of the trimming punches 11 is opened on the lower template 2, a trimming knife head 3 capable of shearing with the trimming punches 11 is arranged at the rear side of the relief groove 21, and a positioning mechanism for positioning the profile product 6 in the width and length directions is further arranged on the lower template 2.

[0039] Place the profile product 6 to be chamfered on the lower template 2, so that two of the angles of the profile product 6 are located above the relief groove 21. After positioning is completed through the positioning mechanism, the upper die assembly and the lower die assembly are closed; when the die is closed, the upper template 1 moves closer to the lower template 2, and the trimming punches 11 are inserted into the relief groove 21. Since the trimming knife head 3 is in contact with the side opposite to the trimming punches 11, and the two trimming punches 11 are distributed in a figure-eight shape, the punching of two angles of the profile product 6 can be completed simultaneously after one die closing.

[0040] Among them, the lower die trimming knife head 3 designs multiple punching clearances according to different materials and thicknesses of the product and marks the punching clearance numbers.

[0041] As described above, guide posts 13 are fixedly installed at the four corners of the upper template 1, and guide holes 24 corresponding to the position and quantity of the guide posts 13 are opened on the lower template 2. When the die is closed, the guide posts 13 slide through the guide holes 24. This structure can ensure the accuracy during die closing and avoid misalignment.

[0042] A plurality of bumps 25 are fixedly installed on the lower template 2, symmetrically distributed in pairs, and the top of the bumps 25 contacts the upper template 1 after mold clamping. The profile product 6 is a narrow and long material, and the stress surface is small when the mold is closed. Here, the bumps 25 are used as the inner limit of the mold, which can keep the upper template 1 in balanced stress and prevent the upper stripping plate (blank holding plate) from deforming and damaging after long-term use.

[0043] As Figures 1 - 4 , Figure 7 shown, the positioning mechanism includes an end positioning block 4 and a positioning component. The former is used for positioning the profile product 6 in the length direction, and the latter is used for positioning the profile product 6 in the width direction. And multiple sets of positioning components are provided, which can meet products of different width dimensions.

[0044] The end positioning block 4 is arranged on the front side of the avoidance groove 21, and the positioning component is arranged on the rear side of the trimming cutter head 3, and the end positioning block 4 is located in the middle position between the two trimming cutter heads 3. The end positioning block 4 can be used to adjust the size of the cut corner, that is, different models of end positioning blocks 4 are designed according to different material widths and cut corner sizes, and the applicable material width and cut corner size numbers are marked on them.

[0045] Among them, in the length direction of the lower template 2, the end close to the end positioning block 4 is the front end, and the opposite end is the rear end.

[0046] The positioning component includes positioning holes 23 and width positioning blocks 5. The positioning holes 23 are opened on the lower template 2 and there are multiple of them, symmetrically distributed in pairs; the lower part of the width positioning block 5 is embedded in the corresponding positioning hole 23, and both sides of the profile product 6 in the width direction are in contact with the upper part of the width positioning block 5.

[0047] Specifically, a width positioning block 5 is embedded in each positioning hole 23 of the positioning component. Each set of positioning components includes at least four positioning holes 23, symmetrically distributed in pairs. The purpose is to provide at least two positions for the profile product 6 in the width direction to ensure the correct position and positioning accuracy of the profile product 6.

[0048] Corresponding positioning holes 23 are designed for different material widths and different cut corner sizes, and anti-mistake is made by the size of the holes. The width adjustment positioning is based on the material width of the product and the position of the positioning hole 23 where it is located. Different models of width positioning blocks 5 are designed and the applicable material width numbers are marked on them; moreover, in one mold clamping, only one set of positioning components is put into use.

[0049] Above, a positioning boss 51 is arranged on the upper part of the width positioning block 5, and the side surface of the profile product 6 is in contact with the side surface of the positioning boss 51. In the width direction, the distance for positioning between two symmetric positioning blocks is determined by the side surface of the positioning boss 51 on its upper part, and this structure can ensure the positioning accuracy in the width direction.

[0050] Further, the top surface of the trimming cutter head 3 is flush with the top surface of the lower template 2. One side of the positioning boss 51 has a notch, and the bottom surface of the notch is not higher than the top surface of the lower template 2, that is, the bottom of the profile product 6 is in contact with the top surface of the lower template 2. Through this structure, the levelness of the profile product 6 can be ensured.

[0051] To facilitate the picking and placing of the profile product 6 on the lower template 2, a material taking groove 26 is provided on the lower template 2. The length direction of the material taking groove 26 is parallel to the width reverse concept stock of the profile product 6, and the material taking groove 26 is located between multiple positioning holes 23.

[0052] To ensure the smooth closing of the upper and lower die assemblies, a first relief hole 12 and a second relief hole 14 corresponding to the end positioning block 4 and the width positioning block 5 respectively are provided on the upper template 1; that is, after closing the die, the end positioning block 4 protruding from the top surface of the lower template 2 is embedded in the first relief hole 12, and the upper part of the width positioning block 5 is embedded in the second relief hole 14 to avoid interference during the closing of the die.

[0053] Working principle:

[0054] According to the material, thickness, width of the profile product 6 and the chamfering size, the corresponding trimming cutter head 3, end positioning block 4 and width positioning block 5 are selected, and the width positioning block 5 is installed in the corresponding positioning hole 23 to complete the width positioning of the product. The end positioning block 4 restricts the chamfering size of the product, and then the punching machine is started to complete the double chamfering punching.

[0058] As Figures 1 - 3 、 Figure 6 shown, a positioning block installation groove 27 for installing the end positioning block 4 is provided on the lower template 2. The end positioning block 4 includes a main body 41 and an extension part 42 integrally formed and connected. The extension part 42 is located on one side of the main body 41, and a pressing boss 43 is provided on the edge of the main body 41 opposite to the extension part 42.

[0059] The lower part of the main body 41 is embedded in the positioning block installation groove 27, and is fixedly installed by pressing it on the pressing boss 43 with a check screw. Moreover, the length of the extension part 42 determines the size of the cut angle of the profile product 6.
