Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and in particular to a hot cutting tool. Background Art

[0002] Automobile interior parts can generally be obtained by low-pressure injection molding or hot pressing to obtain corresponding plastic interior parts; with the improvement of living standards, a layer of leather can be adhered to the surface of the plastic interior parts after low-pressure injection molding or hot pressing to increase the appearance and softness. The adhesion of leather can be achieved by coating or hot pressing lamination.

[0003] Whether it is a plastic interior part formed by low-pressure injection molding or hot pressing, or a multi-layer interior part obtained by coating or hot pressing, after completing the corresponding processing technology, the excess waste of the blank needs to be cut. Take hot pressing as an example. During hot pressing, the area of ​​the leather is larger than the surface area of ​​the plastic interior part. After the pressing is completed, the edge of the blank will extend with excess leather waste, which needs to be cut along the edge contour of the blank to obtain the desired product.

[0004] The existing technology for cutting excess waste mainly places the blank on a fixture for positioning, and then uses a robot to carry a cutting knife to cut along the contour of the blank. However, the processing accuracy required for cutting by the robot is high, which makes the cost of the entire cutting equipment high. In addition, the robot needs to move along the entire contour of the blank, and the position of the robot needs to be adjusted at all times according to the direction of the contour, which will result in a longer cutting process and reduce production efficiency. Based on this, there is an urgent need for a new cutting tool for automotive interior parts. Utility Model Content

DETAILED DESCRIPTION

[0029] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and cannot be understood as limiting the specific scope of protection of the present application.

[0031] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0032] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0033] One of the preferred embodiments of the present application is as follows: Figures 1 to 5 As shown, a hot cutting tool comprises at least one module assembly mounted on a frame 1 and at least one group of cutting assemblies 3. The module assembly is used to place and press the blank 600 to be cut so that the waste edges to be cut of the blank 600 are exposed. Multiple cutting assemblies 3 of each group can be arranged around the module assembly, and each cutting assembly 3 can be driven to perform hot-melt cutting on the waste edges of the blank 600 exposed from the module assembly, so that all the cutting assemblies 3 can perform hot-melt cutting on all the waste edges of the blank 600.

[0034] It should be known that the plurality of cutting components 3 in each group can form a cutting group, and the cutting group can form a cutting area for hot cutting the edge waste of the blank 600. The cutting area can be set according to the specific formation of the automotive interior product, and then when the product is produced, the cutting area can be controlled by controlling the action of the cutting group to achieve one-time cutting of the edge waste of the blank 600. Compared with the traditional method of cutting the waste edge by moving the knife along the edge contour of the blank 600, the production efficiency of the automotive interior product can be effectively improved.

[0035] At the same time, the cutting area formed by the cutting group of the present application cuts the waste edge of the blank 600 by hot-melt cutting. Compared with the traditional method of cutting with a blade, the present application can automatically melt and seal the edges after completing the cutting of the waste edge of the blank 600, so that the edge contour of the product is smooth, thereby effectively improving the production quality of the product. In addition, the present application has relatively low requirements for the design accuracy and subsequent maintenance of the device through hot-melt cutting, while ensuring the cutting production life, it can also effectively reduce production costs. Of course, an exhaust suction device can also be set on the upper part of the frame 1 to collect and discharge the waste gas generated during the hot cutting process.

[0036] It should also be known that the specific number of module components and cutting groups can be selected according to the actual needs of those skilled in the art. In order to further improve the production efficiency of automotive interior products, the number of module components and cutting groups is preferably multiple. Figures 1 to 3 As shown, the number of module components and cutting groups are both two; one module component and the corresponding cutting group can cooperate to form a processing module for product production; the two processing modules can be spaced apart to avoid mutual interference.

[0037] It is understandable that the hot cutting tool of the present application can be applied not only to the hot cutting of automotive interior products, but also to the hot cutting of other products; and the objects of hot cutting are not limited to the leather covering the products, but also can be other materials that can be melted by heating. For the sake of easy understanding, the following content will be described in detail by taking automotive interior products as an example.

[0038] In this embodiment, the module assembly includes an upper module 22 disposed on the upper part of the frame 1, and a lower module 21 disposed on the lower part of the frame 1. The upper end surface of the lower module 21 is provided with a placement groove 210 for placing the blank 600; the upper module 22 can approach the lower module 21 to achieve mold closing, thereby completing the compression of the blank 600 and exposing the edge scrap of the blank 600. More specifically, the up and down movement of the upper module 22 can be achieved by a lifting mechanism 4 disposed on the upper part of the frame 1.

[0039] In this embodiment, there are many specific installation methods for the upper module 22, the lower module 21 and the cutting group. For easy understanding, three examples will be used for detailed description below; the specific installation methods for the upper module 22, the lower module 21 and the cutting group include but are not limited to the following three examples.

[0040] Example 1: Figures 1 to 5As shown, the lower module 21 is fixedly installed at the lower part of the frame 1, and the upper end surface of the lower module 21 is provided with a placement groove 210; the lifting mechanism 4 is installed at the upper part of the frame 1, and the upper module 22 and the cutting group are both installed on the lifting mechanism 4, and the cutting group can be arranged around the upper module 22. When it is necessary to produce the product, the blank 600 to be cut can be placed on the placement groove 210 of the lower module 21; then the lifting mechanism 4 can drive the upper module 22 and the cutting group to move downward synchronously until the upper module 22 and the lower module 21 are matched against each other, so that the upper module 22 cooperates with the placement groove 210 through the lower end surface to form a placement cavity for positioning and pressing the blank 600. Then the cutting group can act to form a cutting area for melting and cutting the edge waste of the blank 600.

[0041] Example 2: The upper module 22 is fixedly installed on the upper part of the frame 1, and the lifting mechanism 4 is installed on the lower part of the frame 1; the lower module 21 and the cutting group are both installed on the lifting mechanism 4, and the cutting group will be arranged around the lower module 21, and the upper end surface of the lower module 21 is provided with a concave placement groove 210. When it is necessary to produce the product, the blank 600 to be cut can be placed on the placement groove 210 of the lower module 21; then the lifting mechanism 4 can drive the lower module 21 and the cutting group to move up synchronously until the upper module 22 and the lower module 21 are matched with each other, so that the upper module 22 cooperates with the placement groove 210 through the lower end surface to form a placement cavity for positioning and pressing the blank 600. Then the cutting group can act to form a cutting area for melting and cutting the edge waste of the blank 600.

[0042] Example 3: The cutting group can be fixedly installed on the frame 1, and the lifting mechanism 4 can simultaneously drive the upper module 22 and the lower module 21 to approach each other toward the position of the cutting group, until the upper module 22 cooperates with the placement groove 210 provided on the upper end surface of the lower module 21 through the lower end surface to form a placement cavity for placing and pressing the blank 600. Then the cutting group can be operated to form a cutting area for melting and cutting the edge waste of the blank 600.

[0043] It can be understood that the above three examples can all meet the requirements of this application. In order to reduce the design difficulty and facilitate product production as much as possible, this embodiment preferably adopts the above-mentioned example one for the specific installation method of the upper module 22, the lower module 21 and the cutting group. The subsequent content will also be explained in detail using example one as an example.

[0044] It should be known that the specific number of cutting components 3 included in the cutting group can be selected according to the specific product shape. Figure 4 and Figure 5As shown, the cutting group includes seven cutting components 3, and the seven cutting components 3 are arranged at intervals along the contour direction of the edge of the blank 600 being pressed. Each cutting component 3 corresponds to a cutting end, and the shapes of the cutting ends of each cutting component 3 are not necessarily the same, and can be specifically set according to the actual formation of the product. In addition, in order to achieve a one-time fusing cutting of the blank 600, when each cutting component 3 is against the edge of the blank 600 being pressed by the cutting end, the cutting ends of adjacent cutting components 3 are continuous with each other, so that the cutting ends of the entire cutting group can form a cutting area corresponding to the edge shape of the blank 600.

[0045] It is understandable that when the cutting group uses multiple cutting components 3 to perform hot-melt cutting of the edge waste of the blank 600, all the cutting components 3 of the cutting group can be operated simultaneously, so that the cutting ends of each cutting component 3 act synchronously to press the edge of the blank 600 to complete the hot-melt cutting together. Of course, the multiple cutting components 3 such as the cutting group can also drive the cutting ends to approach the corresponding positions of the edge of the blank 600 in a set sequence to complete the corresponding hot-melt cutting, until all the cutting components 3 complete the hot-melt cutting of the corresponding positions of the edge of the blank 600 to achieve the hot-melt cutting of the edge waste of the blank 600.

[0046] In this embodiment, there are many specific structures of the cutting component 3. For the sake of easy understanding, one of the structures will be described in detail below. Figure 6 As shown, the cutting assembly 3 includes a mounting seat 31, a displacement device 32 and a cutting knife 34. The entire cutting assembly 3 is fixedly mounted on the lifting mechanism 4 through the mounting seat 31; the displacement device 32 is mounted on the mounting seat 31, and the cutting knife 34 as the cutting end of the cutting assembly 3 is mounted at the output end of the displacement device 32 according to a set angle; the cutting knife 34 can generate heat. When the blank 600 is loaded, the cutting knife 34 can be driven away from the upper module 22 by the displacement device 32, and then when the upper module 22 and the lower module 21 are attached to each other, the cutting knife 34 can avoid contacting with the edge waste edge of the blank 600 to affect the positioning and pressing of the blank 600. When the edge waste edge of the blank 600 needs to be cut, the cutting knife 34 can be driven by the displacement device 32 to move to the position of the placement cavity until the cutting end presses the edge of the blank 600 exposed from the placement cavity and performs the melting and cutting of the waste edge.

[0047] It is understandable that there are multiple specific installation methods for the cutting knife 34 to correspond to the edge of the blank 600. The output end of the displacement device 32 may be equipped with a connecting plate 33, and the cutting knife 34 may be installed on the connecting plate 33 at a set angle, so that the cutting knife 34 can be aligned and pressed with the edge contour of the blank 600 under the drive of the displacement device 32. Of course, the displacement device 32 and the cutting knife 34 may also be installed on the mounting seat 31 at a set angle, and then the cutting knife 34 may be aligned and pressed with the edge contour of the blank 600 under the drive of the displacement device 32. Both of the above-mentioned installation methods can meet the requirements of this application. In order to facilitate the description of the subsequent content, the subsequent content will be described in detail by taking the displacement device 32 installed on the mounting seat 31 at a set angle as an example.

[0048] It should be known that one end of the mounting seat 31 can be detachably mounted on the lifting mechanism 4 by means of fasteners such as bolts, and the other end of the mounting seat 31 can be provided with a mounting plane with a corresponding tilt angle according to the cutting position of the blank 600 corresponding to the cutting assembly 3. The displacement device 32 can be stably mounted on the mounting plane of the mounting seat 31 by means of fasteners. The specific structure and working principle of the displacement device 32 are well known to those skilled in the art, so they will not be elaborated in detail here; common displacement devices 32 include linear motors, cylinders, hydraulic cylinders, etc., and hydraulic cylinders are preferably used in this embodiment.

[0049] Specifically, Figure 6 and Figure 7 As shown, in order to facilitate the installation of the cutting knife 34, a connecting plate 33 is installed at the output end of the displacement device 32, and the cutting knife 34 can be detachably fixed to the connecting plate 33 through a fixing block 341 arranged on the side away from the cutting direction, thereby facilitating the installation and replacement of the cutting knife 34 without hindering the cutting by the cutting knife 34.

[0050] In this embodiment, Figures 7 to 10 As shown, a sharp corner is provided on one side of the cutting blade 34, and the cutting blade 34 can be pressed against the edge of the blank 600 at the sharp corner position, and then the edge waste of the blank 600 is melted and cut by heating at the sharp corner position. The sharp corner can be conveniently used to concentrate heat, so that while hot cutting of the blank 600 is achieved, the heating power can be reduced to reduce the waste of resources. In addition, the setting of the sharp corner can also improve the accuracy of cutting the edge waste of the blank 600, so as to further improve the position cutting accuracy and cutting quality of the edge waste of the blank 600.

[0051] In this embodiment, there are many ways for the cutting knife 34 to fuse and cut the waste edge of the blank 600 by heating. For easy understanding, two specific examples are used to explain in detail below.

[0052] Specific example 1:

[0053] like Figures 7 to 9 As shown, a heating wire 500 is externally arranged at the sharp corner position of the cutting knife 34; thus, when hot cutting the waste edge of the blank 600, the cutting knife 34 can be directly pressed against the edge of the blank 600 through the heating wire 500 at the sharp corner position, and then the waste edge of the blank 600 can be directly melted and cut by the electric heating of the heating wire 500.

[0054] Specifically, the angle position of the cutting blade 34 is provided with an inwardly concave mounting groove 340, and the heating wire 500 can be stably mounted outside the sharp corner of the cutting blade 34 through the mounting groove 340. The specific structural setting of the mounting groove 340 can be specifically designed according to the structural shape of the cutting blade 34. If the sharp corner of the cutting blade 34 is a straight structure, that is, the edge of the blank 600 cut by the cutting blade 34 is a straight line segment; then the mounting grooves 340 can be evenly distributed along the extension direction of the sharp corner of the cutting blade 34, that is, Figure 7 As shown; of course, the mounting grooves 340 can also be arranged on both sides of the sharp corner of the cutting blade 34, and then the heating wire 500 is engaged with the mounting grooves 340 on both sides of the sharp corner to achieve positioning and tensioning. If the sharp corner of the cutting blade 34 is a non-straight structure, such as an arc or a broken line, in order to ensure that the heating wire 500 heats the blank 600 stably, the mounting grooves 340 must be evenly distributed along the extension direction of the sharp corner.

[0055] It should be known that the depth of the mounting groove 340 should not be too deep. If the mounting groove 340 is too deep, the height of the heating wire 500 exposed from the mounting groove 340 will be shorter, and the side of the mounting groove 340 will easily interfere with the blank 600 when the waste edge of the blank 600 is cut, thereby affecting the molding quality of the blank 600. Of course, the depth of the mounting groove 340 should not be too shallow. If the mounting groove 340 is too shallow, the installation of the heating wire 500 will be unstable, and when the blank 600 is hot-cut, the heating wire 500 and the mounting groove 340 will be easily separated when the heating wire 500 and the blank 600 are squeezed, thereby causing the cutting position of the heating wire 500 to deviate and cause waste. Therefore, in this embodiment, the depth X of the mounting groove 340 is 20% to 60% of the cross-sectional diameter of the heating wire 500, preferably 40% to 50% of the cross-sectional diameter of the heating wire 500.

[0056] In this example, if Figure 7 and Figure 8 As shown, when installing the heating wire 500, after the heating wire 500 is installed in the installation groove 340 at the sharp corner of the cutting knife 34, the wire end of the heating wire 500 can be penetrated by the fixing block 341 set on the other side of the cutting knife 34, and then the wire end of the heating wire 500 can be protected to avoid affecting the power supply of the heating wire 500.

[0057] Specifically, Figure 7 and Figure 8 As shown, the fixing block 341 is provided with a threading hole 3410 that penetrates along the extending direction of the sharp corner of the cutting knife 34, and a connecting port 3411 that is perpendicular to the threading hole 3410. One end of the connecting port 3411 is connected to the middle of the threading hole 3410, and the other end is connected to the outside. Therefore, when installing the heating wire 500, the two ends of the heating wire 500 can extend into the threading hole 3410 at the ends of the threading holes 3410 corresponding to the sharp corners of the cutting knife 34, and then pass through the connecting port 3411 together to achieve circuit connection. By providing the threading hole 3410, the heating wire 500 can be protected on the one hand, and the heating wire 500 can be restrained on the other hand to ensure the stable installation of the heating wire 500.

[0058] In this example, if the cutting blade 34 is made of insulating material, the heating wire 500 can directly use a resistance wire. If the cutting blade 34 is made of non-insulating material, the heating wire 500 can include a shell and a resistance wire, the resistance wire is arranged inside the shell, and the shell is filled with insulating filler, so that the resistance wire and the shell are spaced apart, thereby avoiding the influence of the power supply of the resistance wire on the shell. In order to ensure the transmission efficiency of the heating of the resistance wire, the shell of the heating wire 500 is made of metal material, and the insulating filler can be made of alumina powder, which not only has good thermal conductivity but also good insulation. If the cross-sectional size of the heating wire 500 is small enough, the cross-sectional shape of the shell can be circular; if the cross-sectional size of the heating wire 500 is large, the cross-sectional shape of the shell can be set with a sharp corner, so that the cutting blade 34 performs hot melt cutting on the edge of the blank 600 through the sharp corner formed by the heating wire 500.

[0059] Specific example 2:

[0060] like Fig.10 As shown, a heating wire 500 is provided inside the cutting blade 34 near the sharp corner. Therefore, when performing hot cutting of the edge waste of the blank 600, the cutting blade 34 can be pressed against the edge of the blank 600 through the sharp corner, and then the sharp corner is heated by the heating wire 500 to achieve the melting of the waste edge of the blank 600. Compared with the direct hot cutting in the specific example 1, this example heats the sharp corner of the cutting blade 34 by the heating wire 500 to achieve the hot cutting of the waste edge of the blank 600.

[0061] In this example, if Fig.10 As shown, the interior of the cutting blade 34 is filled with a filler 342 , thereby ensuring that the heating wire 500 is installed in the interior of the cutting blade 34 , thereby ensuring that the heating wire 500 heats the sharp corner of the cutting blade 34 evenly.

[0062] It should be noted that if the inside of the cutting blade 34 is a hollow structure, the heating wire 500, after being installed inside the cutting blade 34, is prone to position deviation during the movement of the cutting blade 34, thereby causing uneven heating at the sharp corner of the cutting blade 34, thereby affecting the quality and efficiency of waste edge cutting of the blank 600. Filling the inside of the cutting blade 34 can stabilize the installation position of the heating wire 500, thereby ensuring uniform heating of the cutting blade 34.

[0063] It is understandable that in the process of heating the heating wire 500, in order to reduce the waste of energy, the cutting blade 34 adopts a material with good thermal conductivity and high structural strength, such as metal. The filler 342 filled inside the cutting blade 34 needs to have good thermal conductivity so as to efficiently transfer the heat generated by the heating wire 500 to the sharp corner of the cutting blade 34. There are many types of fillers 342 with good thermal conductivity, and the common ones are aluminum oxide powder, aluminum nitride powder and silicon nitride powder. The filler 342 in powder form is not only convenient for filling, but also can be stably positioned by pressing the heating wire 500. In order to further ensure the heat transfer efficiency of the heating wire 500, the heating wire 500 can directly adopt a resistance wire, and then the filler 342 also needs to have an insulating effect to avoid electrical contact between the heating wire 500 and the cutting blade 34.

[0064] Of course, in order to further ensure the heat transfer efficiency of the heating wire 500, the value of the distance Y from the heating wire 500 to the sharp corner of the cutting knife 34 should not be too large; generally speaking, the value of the distance Y from the heating wire 500 to the sharp corner of the cutting knife 34 can be less than or equal to 3 times the cross-sectional diameter of the heating wire 500, preferably 1.5 to 2 times the cross-sectional diameter of the heating wire 500.

[0065] In this embodiment, in order to realize hot cutting of products of different types or sizes to increase the application scope of the present application, the upper module 22, the lower module 21 and the hot cutting group can be designed to be replaceable; so that the corresponding upper module 22, the lower module 21 and the hot cutting group can be replaced for different products to realize product processing. There are many specific design methods that can realize the replacement of the upper module 22, the lower module 21 and the hot cutting group. For the sake of easy understanding, the following will be described in detail through one of the specific structures.

[0066] Specifically, Figures 1 to 3As shown, the lower part of the frame 1 is detachably mounted with a lower support 11, and the lower module 21 is detachably mounted on the lower support 11 at the lower part of the frame 1. The lifting mechanism 4 includes an upper support 41 and a mounting plate 42; the upper support 41 is vertically slidably mounted on the frame 1, and the mounting plate 42 is detachably mounted on the lower end surface of the upper support 41, and the mounting plate 42 is used to install the upper module 22 and the cutting group. Therefore, when hot cutting of different products is required, the lower support 11 can be disassembled and replaced with a new lower support 11, and the lower module 21 at the lower part of the frame 1 will also be replaced with the lower module 21 corresponding to the new product; at the same time, the mounting plate 42 is removed from the upper support 41 and a new mounting plate 42 is installed, and the upper module 22 and the cutting group are also replaced with the upper module 22 and the cutting group corresponding to the new product; and then the hot cutting processing of the new product is completed by lifting and lowering the lifting mechanism 4.

[0067] It should be known that there are many ways to drive the upper support 41 to be lifted vertically along the frame 1, such as using a cylinder, a hydraulic cylinder or a linear motor for vertical drive, or using a gear and rack meshing drive mode.
