Description

Technical Field

[0001] This utility model belongs to the technical field of punching equipment for interlocking floorboards, specifically relating to a die device for cutting interlocking floorboards. Background Technology

[0002] Interlocking flooring, also known as click-lock flooring, connects adjacent planks through an interlocking mechanism along their edges, eliminating the need for glue or mechanical fixing. This simplifies installation, increases manual installation efficiency, and facilitates future maintenance and replacement. Due to its ease of installation and use, it is widely used in homes, public buildings, and other locations, with demand increasing year by year both domestically and internationally, making it one of the mainstream choices for modern interior design.

[0003] In the processing of interlocking flooring, precision cutting is a crucial step, specifically involving the accurate cutting of large-format semi-finished boards into single, standard-sized flooring strips. Currently, the industrial processing of interlocking flooring commonly employs stamping cutting technology. This involves using a die mounted on a large hydraulic press to stamp the flooring board in a single pass, simultaneously completing the precise cutting of the flooring's perimeter and the interlocking structure at the edges.

[0004] In the existing technology, the cutting die tool for cutting interlocking flooring is equipped with a cutting blade. The cutting blade is a core component, and its installation, debugging and maintenance will have a great impact on the yield rate of flooring processing.

[0005] Currently, it is difficult to unify the mounting reference surface of blades in die-cutting molds, making it challenging to ensure levelness. Blades may exhibit uneven levelness due to installation stress or reference surface errors, resulting in uneven force during cutting and mold closing. Furthermore, the cutting edge height cannot be fine-tuned, and inaccurate tool setting can easily lead to cutting edge deviation. However, the height of the blade mounting on traditional molds is fixed. If machining errors or blade wear cause deviations in cutting edge height, fine-tuning and maintenance are difficult, and the adjustment accuracy is hard to guarantee.

[0006] In summary, current cutting molds lack adjustment mechanisms for the blade's horizontal plane and cutting edge height, making the blade prone to slight misalignment or displacement during the cutting process. This not only affects the cutting quality of the sheet metal, causing problems such as burrs and tears on the edges, but also damages the cutting edge and affects the blade's service life. Summary of the Invention

[0007] The purpose of this invention is to solve the problem in the prior art where the cutting die lacks an adjustment mechanism for the levelness and cutting edge height after the blade is installed, leading to decreased cutting quality and shortened blade life. Therefore, this invention provides a cutting die device for cutting interlocking floor panels.

[0008] To achieve the above objectives, the present invention proposes the following technical solution: A die-cutting device for cutting interlocking floorboards includes a first template, a first pad, a second pad, and an alignment mechanism. The first template and the first pad are both provided with a plurality of the aforementioned alignment mechanisms. The first template is positioned above the first pad through the alignment mechanisms, and the first template reciprocates in a direction that approaches or moves away from the first pad. The first template further includes a first mold core and several cutting components. The first mold core is disposed on the lower surface of the first template, and the cutting components are fixed to the first mold core and are disposed toward the first pad. The second pad is removably mounted on the first pad and is used to adjust the effective working stroke of the cutting component. The effective working stroke is the distance between the lower surface of the first mold core and the cutting edge of the cutting component, and is used to cut the workpiece. The second pad includes an adjustment state and a working state; In the adjusted state, the second pad is placed on the first pad, and the first template moves down to above the second pad, so that the cutting component contacts the upper surface of the second pad and the cutting component is fixedly installed on the first mold core; In the operating state, the second pad is removed, and the cutting component processes the workpiece placed on the first pad.

[0009] Furthermore, the first mold core includes a plurality of spaced mounting strips, the mounting strips being fixed to the lower surface of the first mold core, and the lower surface of the mounting strips being close to the first pad; The extension direction of the mounting strip is parallel to the extension direction of the first template. The cutting component is fixedly mounted on the side of the mounting strip adjacent to the lower surface. The cutting edge of the cutting component is set towards the first pad. The cutting edge of the cutting component protrudes downward from the lower surface of the mounting strip and contacts the upper surface of the second pad. The protruding height of the cutting edge is the distance between the lower surface of the mounting strip and the cutting edge of the cutting component, which is equal to the effective working stroke.

[0010] Furthermore, in the adjusted state, the distance between the lower surface of the mounting strip and the upper surface of the second pad is equal to the protrusion height of the cutting edge; When the distance between the lower surface of the mounting strip and the upper surface of the first pad is fixed, the thickness of the second pad is adjusted so that the protruding height of the cutting edge is adapted to the effective working stroke.

[0011] Furthermore, the cutting component includes a cutting blade, which includes at least a single-bevel blade and a double-bevel blade; The single-beveled blades are rectangularly distributed around the first mold core, and the double-beveled blades are arranged side by side within a rectangular frame formed by several single-beveled blades. The included angle of the cutting edge of the single-bevel blade is 10°-20°; The included angle of the cutting edge of the double-beveled blade is 20°-30°.

[0012] Furthermore, the second pad has a clearance portion on the side near the first template. When the second pad is in the adjustment state, the cutting component is at least partially accommodated within the clearance portion.

[0013] Furthermore, the clearance portion includes at least one receiving groove, which is adapted to the shape and position of the cutting component.

[0014] Furthermore, the depth of the receiving groove is greater than or equal to the effective working stroke of the cutting component.

[0015] Furthermore, the device includes a height adjustment mechanism, and the cutting component is mounted to the mounting strip via the height adjustment mechanism; The height adjustment mechanism includes a fastening component and a reinforcement component; The fastening assembly includes a plurality of mounting slots, a plurality of first mounting holes, and a plurality of fasteners. The mounting slots are disposed through the side of the mounting strip adjacent to its lower surface, and the first mounting holes are disposed through the side of the cutting component. The mounting slots, the first mounting holes, and the fasteners are disposed correspondingly. The mounting groove is configured as a long strip shape along the vertical direction; The cutting component is movably connected to the mounting groove by a fastener passing through the first mounting hole. By adjusting the position of the fastener in the mounting groove, the fixed position of the cutting component relative to the lower surface of the mounting strip can be adjusted.

[0016] Furthermore, the height adjustment mechanism also includes a reinforcement component; The reinforcement component includes several elongated reinforcement members, the extension direction of which is parallel to the extension direction of the cutting component; The reinforcement is provided with a plurality of second mounting holes, and the second mounting holes are provided in correspondence with the first mounting holes; The fasteners are sequentially inserted into the mounting groove, the first mounting hole, and the second mounting hole, and the fasteners are installed and fixed to the cutting component on the opposite side of the mounting strip. Then, the fasteners and the cutting component are simultaneously installed and fixed to the mounting strip, so that the fasteners press the cutting component and fix it to the mounting strip.

[0017] Furthermore, the alignment mechanism includes positioning holes and positioning rods, and the edge of the first pad is provided with a plurality of support positioning holes; The positioning rod is fixedly installed on the first pad through the support positioning hole, and the positioning rod extends in the vertical direction; The first template has several first positioning holes on its edge. The first template is fitted onto the positioning rod through the first positioning holes and moves back and forth along the positioning rod towards or away from the first pad.

[0018] The beneficial effects of this utility model are: (1) By setting an alignment mechanism, this utility model ensures that the first template and the lower pad are kept in the same position during punching, preventing the first template from shifting and causing the cutting position of the tool to shift, thus affecting the processing quality of the plate. On the other hand, it enables the first template to maintain the same level as the lower pad, which facilitates the subsequent installation and maintenance of the cutting tool, and the cutting edge direction is not easily shifted.

[0019] (2) This utility model sets a second pad as an adjustment component of the die mold, which is used to fine-tune and maintain the installation angle and blade protrusion height of the cutting tool in the adjustment state. Based on the above alignment mechanism, in conjunction with the second pad, it can be used as the blade installation reference surface to ensure that the cutting tool is in the same level as the first template and the first pad when it is installed, and avoid the blade from being uneven in level due to installation stress or reference surface error, which would lead to uneven force during cutting.

[0020] (3) This utility model sets a second pad as an adjustment component of the die mold, and sets a receiving groove on the second pad so that its shape and position fit the cutting edge of the blade. By setting and adjusting the depth of the receiving groove, the installation height of the cutting edge can be adjusted. When the cutting edge height needs to be adjusted according to actual needs or when the cutting edge is worn due to use, the cutting edge height can be easily adjusted through receiving grooves of different depths and specifications, which is convenient for daily fine-tuning and maintenance and effectively improves the cutting quality of the plate.

[0021] (4) By setting a height adjustment mechanism and combining it with the second pad mentioned above, the height and level of the cutting edge can be adjusted according to actual needs. At the same time, the reinforcing component in the height adjustment mechanism can press and fix the cutting blade on the mold core, so as to prevent the cutting blade from loosening due to stress and vibration during the stamping process, which would cause deviation and affect the processing effect of the sheet metal.

[0022] (5) By setting the cutting edge angle of the cutting blade, this utility model effectively reduces the cutting force of the blade during punching, significantly reduces the tearing and edge burr formation during plate cutting, effectively slows down the tensile deformation near the blade, extends the service life of the tool, improves the cutting accuracy of the plate, and effectively reduces the scrap rate.

[0029] See attached document Figure 1 and attached Figure 2 As shown, this utility model provides a die-cutting device for cutting interlocking floorboards, including a first template 1, a first pad 2, a second pad 3, an alignment mechanism, and a height adjustment mechanism.

[0030] The first template 1 is positioned above the first pad 2, with the first template 1 facing downwards towards the first pad 2, and the lower surface of the first template is provided with a first mold core 11.

[0031] The first mold core 11 includes a number of spaced mounting strips 110, which are fixed to the lower surface of the first mold core 11 and the lower surface of the mounting strips 110 is close to the first pad 2.

[0032] The mounting strip 110 extends in a direction parallel to the extension direction of the first template 1. Several cutting components are mounted and fixed on the side of the mounting strip 110 near its lower surface. The cutting components include, but are not limited to, cutting blades 12. The cutting edge of the cutting blades 12 is set towards the first pad 2.

[0033] The cutting edge of the cutting blade 12 protrudes downward from the lower surface of the mounting strip 110 and contacts the upper surface of the second pad 2. This protrusion distance is the cutting edge protrusion distance.

[0034] The effective working stroke of the cutting blade 12 is the distance between the lower surface of the mounting strip 110 and the cutting edge of the cutting blade 12, used for cutting the workpiece. The aforementioned cutting edge protrusion distance is equal to the effective working stroke of the cutting blade 12.

[0035] The alignment mechanism includes positioning holes and positioning rods 22. The edge of the first pad 2 is provided with several supporting positioning holes 21. The positioning rods 22 are fixedly installed on the first pad 2 through the supporting positioning holes 21, and extend vertically. The edge of the first template 1 is provided with several first positioning holes 13. The first template 1 is fitted onto the positioning rods 22 through the first positioning holes 13, and reciprocates along the positioning rods 22, moving closer to or further away from the first pad 2.

[0036] During sheet processing, the sheet to be processed is placed on the upper surface of the first pad 2. The upper surface of the first template 1 is connected to a hydraulic mechanism. Under the drive of the hydraulic mechanism, the first template 1 moves downward along the positioning rod 22 to punch. The cutting blade 12 faces downward and contacts the sheet to be processed placed on the upper surface of the first pad 2, performing punching or die-cutting operations to cut the sheet into the specified shape.

[0037] During this process, the alignment mechanism ensures that the first template 1 does not shift during its vertical movement, thereby preventing the cutting position from deviating from the designated position and affecting the cutting quality of the board.

[0038] See attached document Figure 3 As shown, the cutting blade 12 includes a single-bevel blade and a double-bevel blade. Each blade has two cutting faces, and the included angle between the two cutting faces is the cutting edge angle, as shown in the attached figure. Figure 3 (a) and appendix Figure 3 In (b), the included angles of the cutting edges of the single-beveled blade and the double-beveled blade are α and β, respectively.

[0039] The single-beveled blades are arranged in a rectangular pattern around the first mold core 11, and the double-beveled blades are arranged side by side within a rectangular frame formed by several single-beveled blades.

[0040] In some alternative embodiments, the distribution pattern of the cutting blades can be designed and adjusted according to the actual situation.

[0041] Preferably, the included angle α of the cutting edge of the single-bevel blade is 10°-20°.

[0042] When the included angle α of the cutting edge of a single beveled blade is greater than 20°, the force on the blade during punching increases by 15-25%, the width of tensile deformation near the blade cut increases by 30-50%, and there are more cutting tears and edge burrs, with the burrs increasing by 20-40 μm.

[0043] Further preferred, the blade edge angle α of the single-bevel blade is 15°. At this angle, the cutting resistance is lower, the edge burrs are significantly reduced, the deformation near the blade cut is reduced, and the tool life is improved.

[0044] Preferably, the included angle β of the double-beveled blade is 20°-30°.

[0045] More preferably, the included edge angle β of the double-beveled blade is 25°.

[0046] In some preferred embodiments, the cutting blade 12 is made of powder high-speed steel PM4 / PM23 with a hardness of HRC64-66. Combined with the blade angle design described above, the cutting accuracy can be significantly improved and the processing quality of the interlocking floorboards can be enhanced.

[0047] See attached document Figure 4 and attached Figure 5 As shown, the cutting blade 12 is mounted on the mounting strip 110 via a height adjustment mechanism.

[0048] The height adjustment mechanism includes a fastening component and a reinforcement component. The fastening component includes a plurality of mounting grooves 111, a plurality of first mounting holes 120 and a plurality of fasteners. The mounting grooves 111 are provided through the side of the mounting strip 110 adjacent to the lower surface, and the first mounting holes 120 are provided through the side of the cutting blade 12.

[0049] The mounting slot 111, the first mounting hole 120 and the fastener are set accordingly, and the mounting slot 111 is set into a long strip shape along the vertical direction.

[0050] The cutting blade 12 is movably connected to the mounting groove 111 by a fastener that passes through the first mounting hole 120. By adjusting the position of the fastener in the mounting groove 111, the fixed position of the cutting blade 12 relative to the lower surface of the mounting strip 110 is adjusted, thereby precisely adjusting the protrusion height of the cutting edge in the adjustment state to reach the preset value.

[0051] The fasteners include screws and nuts. The first mounting hole 120 is a threaded hole, and the cutting blade 12 is mounted to the mounting strip 110 by screws. The screw passes through the washer and the mounting groove 111 in sequence, and finally screws into the first mounting hole 120. During initial installation, the screw is loosened, and the cutting blade 12 falls into the mounting groove 111 under gravity to a manually adjustable position. After the blade protrusion height is adjusted to the predetermined value by the second pad 3, the screw is tightened. The clamping force between the screw head and the edge of the mounting groove 111 securely locks the cutting blade 12 in the current position.

[0052] The reinforcement assembly includes several elongated reinforcement members 14, the extension direction of which is parallel to the extension direction of the cutting blade 12.

[0053] The reinforcement member 14 is provided with a plurality of second mounting holes 140, which are correspondingly provided with the first mounting holes 120. Fasteners are sequentially inserted into the mounting groove 111, the first mounting holes 120 and the second mounting holes 140, thereby simultaneously installing and fixing the reinforcement member 14 and the cutting blade 12 onto the mounting strip 110, so that the reinforcement member 14 presses the cutting blade 12 and fixes it to the mounting strip 110.

[0054] The reinforcement 14 can be made of reinforcing steel bars. By installing and fixing the reinforcement 14 to the cutting blade 12 on the opposite side of the mounting strip 110, the reinforcement 14 provides a uniform clamping force to the cutting blade 12, which greatly improves the rigidity and impact resistance of the cutting blade 12 and prevents the cutting blade 12 from becoming slightly loose or displaced when subjected to high-intensity, high-frequency punching forces, thereby affecting the cutting quality.

[0055] The second pad 3 is removably mounted on the first pad 2 and is used to adjust the effective working stroke of the cutting blade 12, which is the protrusion height of the cutting edge of the cutting blade 12 used for cutting the plate. This is the distance between the lower surface of the mounting strip 110 and the cutting edge of the cutting blade 12. In the adjustment state, by adjusting the thickness of the second pad 3, the distance between the lower surface of the mounting strip 110 and the upper surface of the second pad 3 is made equal to the preset protrusion height of the cutting edge, thereby adjusting the protrusion height of the cutting edge.

[0056] The second pad 3 includes both adjustment and working states.

[0057] In the adjustment state, the second pad 3 is placed on the first pad 2, the first template 1 moves down to above the second pad 3, so that the cutting blade 12 contacts the upper surface of the second pad 3, and the cutting blade 12 is fixedly installed on the mounting strip 110.

[0058] On the one hand, combined with the above-mentioned alignment mechanism, it can be ensured that the first template 1 and the first pad 2 are at the same level. Therefore, the upper surface of the second pad 3 placed on the first pad 2 is also at the same level. The lower edge of the cutting blade 12 contacts the upper surface of the second pad 3. At this time, the cutting blade 12 can be fixed according to its position in the mounting groove 111, thereby confirming and fine-tuning the level of the cutting blade 12.

[0059] On the other hand, by adjusting the downward distance of the first template 1 and the thickness of the second pad 3, the distance between the lower surface of the mounting strip 110 and the upper surface of the second pad 3 can be precisely adjusted, and the cutting blade 12 can be installed on the mounting strip 110 to obtain the corresponding blade protrusion height.

[0060] Different blade protrusion heights can be selected according to actual needs. For ease of operation, with the distance between the lower surface of the mounting strip 110 and the upper surface of the first pad 2 fixed, the thickness of the second pad 3 can be adjusted independently to flexibly adjust the blade protrusion height. In this process, only second pads 3 of different thicknesses need to be prepared in advance, without the need for precise manual or machine control. The thickness of the second pad 3 can be set accordingly to meet actual needs.

[0061] In operation, the second pad 3 is removed, and the cutting blade 12 normally processes the workpiece placed on the first pad 2.

[0062] See attached document Figure 6 As shown, in some optional embodiments, the side of the second pad 3 facing the first template 1 is provided with a clearance portion, and when the second pad 3 is in the adjustment state, the cutting blade 12 is at least partially accommodated in the clearance portion.

[0063] The aforementioned clearance portion includes, but is not limited to, a receiving groove 31 that matches the cross-sectional contour and position of the cutting blade, and also includes structures such as holes or recesses, for integral processing of the sheet metal and splicing parts.

[0064] The depth of the receiving groove 31 is greater than or equal to the preset protrusion height of the cutting edge of the cutting blade 12. During the adjustment process, the first template 1 moves downward, and the cutting blade 12 at the corresponding position is precisely embedded in the corresponding receiving groove 31 until the lower surface of the mounting strip 110 contacts and adheres to the upper surface of the second pad 3, thus ensuring that the depth of the receiving groove 31 is at least equal to the distance by which the cutting edge of the cutting blade 12 protrudes from the lower surface of the mounting strip 110.

[0065] As attached Figure 6 (a) and appendix Figure 6In (b), the depths of the receiving grooves 31 corresponding to the single-bevel blade and the double-bevel blade are a and b, respectively, which correspond to the protrusion heights of the single-bevel blade and the double-bevel blade, respectively. At the same time, the included angles of the two sides of the recessed receiving groove 31 are α and β, respectively, which correspond to the included angles of the blade edges of the single-bevel blade and the double-bevel blade. When the cutting blade 12 is embedded in the corresponding receiving groove 31, the two blade surfaces of the cutting blade 12 can be attached to the inner wall of the receiving groove 31, respectively. At this time, the installation position and height of the cutting blade 12 can be finely adjusted and fixed, thereby accurately adjusting the protrusion height of the blade edge.

[0066] Preferably, the depth of the receiving groove 31 is equal to the preset protrusion height of the corresponding cutting blade 12.

[0067] The upper surface of the second pad 3 is provided with at least one receiving groove 31. The receiving groove 31 can be set according to the installation position and depth of the cutting blade 12. Different shapes and depths of receiving grooves 31 can also be processed on multiple second pads 3 for easy replacement in the future.

[0068] The above solution avoids rigid contact between the cutting edge of the cutting blade 12 and the surface of the second pad 3, thus preventing the cutting edge from cracking or wearing. At the same time, during adjustment, the second pad 3 prevents the cutting edge from contacting the upper surface of the first pad 2, thereby affecting the adjustment accuracy.

[0069] On the other hand, depending on the needs of the processed sheet material or the offset and wear of the cutting edge during use, the protrusion height of the cutting edge needs to be adjusted accordingly. Different sizes of cutting blades 12 can be adjusted using accommodating grooves 31 of different depths and shapes according to actual needs, or an array of accommodating grooves 31 of different depths and shapes can be designed on the second pad 3 to facilitate real-time use and adjustment, and meet the actual needs of sheet material processing.

Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
