A sawtooth metal strip forming device includes: an upper toothed cutter wheel and a lower toothed cutter wheel. The upper and lower toothed cutter wheels are respectively provided with a first surface and a second surface. The edges of the first and second surfaces are surrounded by a plurality of teeth and grooves, so that the teeth of the upper toothed cutter wheel are aligned with the grooves of the lower toothed cutter wheel, and the grooves of the upper toothed cutter wheel are aligned with the teeth of the lower toothed cutter wheel. Accordingly, a continuous metal strip is conveyed to this device and cut along the center line by the upper and lower toothed cutter wheels to become two continuous sawtooth metal strips. After being rolled flat and cut to an appropriate length, an even number of sawtooth metal strips without waste are obtained. When the teeth or grooves of the first surface of the upper or lower toothed cutter wheel become dull and unusable, only the surface needs to be replaced to continue production. This not only greatly reduces the cost of purchasing tools, but also improves production efficiency.

Description

Serrated metal strip forming device Technical Field

[0001] This invention provides a technical field for serrated metal strips, and more particularly, it provides a serrated metal strip forming device, wherein the upper and lower toothed cutting wheels roll and produce an even number of serrated metal strips without waste. When the first surface of the upper or lower toothed cutting wheel becomes dull, production can continue by simply replacing it with the second surface of the upper or lower toothed cutting wheel, which greatly improves work efficiency and reduces the cost of purchasing cutting tools. Prior Technology

[0002] As shown in Figures 8 and 9, the conventional method of manufacturing serrated metal strips involves stamping with a die, where the upper die 11 presses against the lower die 12 to cut the metal strip 13 into a serrated shape 131, simultaneously slicing the metal strip 13 to ensure each strip is the required length. This metal strip 13 can be used in corrosion-resistant and slip-resistant workbenches or ladders, where the serrated shape 131 increases friction. However, while the conventional method uses the upper die 11 to press against the lower die 12 to create serrated metal strips, the grooves 132 of the serrated shape 131, combined with the variations in the serrated teeth and grooves, result in scrap material 14 at the cut-out protrusions. Therefore, the conventional stamping method generates 10% more scrap material 14, increasing costs by 10%, making it less competitive in the market. On the other hand, the length of the metal strip 13 needs to be determined according to customer requirements. However, changing the length of the metal strip 13 using conventional stamping dies is quite difficult and may require replacing the entire set of dies. Furthermore, the stamping method requires calculating the time it takes for the upper die 11 to reach the lower die 12 plus the time it takes for the upper die 11 to return to its original position for each metal strip 13 to be produced, which results in low production efficiency and needs to be improved.

[0003] The inventor previously developed a "serrated metal strip forming device" and applied for and was granted patent certificate number M564491. The conventional serrated metal strip forming device includes: a set of upper and lower toothed cutter wheels, including an upper toothed cutter wheel, one of which has a plurality of teeth and grooves around its right side; a lower toothed cutter wheel, the left side of which is located near the right side of the upper toothed cutter wheel, one of which has a plurality of teeth and grooves around its left side, with the lower toothed cutter wheel teeth aligned with the upper toothed cutter wheel grooves, and the lower toothed cutter wheel grooves aligned with the upper toothed cutter wheel teeth. In this way, continuous metal strips are conveyed to this location and cut along the center line of the upper and lower toothed cutter wheels to become two continuous serrated metal strips. After being rolled flat and cut to an appropriate length, an even number of serrated metal strips without waste are obtained. However, both the upper and lower gear cutting wheels only have teeth and grooves on one side. Therefore, after they become dull, the entire upper or lower gear cutting wheel needs to be removed and replaced with a newly purchased gear cutting wheel. This makes the cost of purchasing the cutting tools quite high, and it is also impossible to know when the cutting tools will be damaged. This not only affects production efficiency but also keeps the cost of the cutting tools high.

[0004] Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop a more ideal and practical innovative structure is what consumers eagerly expect, and it is also the goal and direction that relevant businesses must strive to achieve through research and development.

[0005] In view of this, the creator, based on years of experience in manufacturing, developing and designing related products, has designed and carefully evaluated the above objectives, and finally created a work that is truly practical. Summary of the Invention

[0006] The main purpose of this invention is to provide a serrated metal strip forming device, in which upper and lower toothed cutter wheels roll and produce an even number of serrated metal strips without waste. When the first surface of the upper or lower toothed cutter wheel becomes dull, production can continue by simply replacing it with the second surface of the upper or lower toothed cutter wheel, which greatly improves work efficiency and reduces the cost of purchasing cutting tools.

[0007] To achieve the above objectives, this invention provides a sawtooth metal strip forming device, comprising: an upper toothed cutter wheel and a lower toothed cutter wheel. The upper and lower toothed cutter wheels are respectively provided with a first surface and a second surface. The edges of the first and second surfaces are surrounded by a plurality of teeth and grooves, with the teeth of the upper toothed cutter wheel aligned with the grooves of the lower toothed cutter wheel, and the grooves of the upper toothed cutter wheel aligned with the teeth of the lower toothed cutter wheel. Accordingly, continuous metal strips are conveyed here and cut along the center line by the upper and lower toothed cutter wheels to become two continuous sawtooth metal strips. After being rolled flat and cut to an appropriate length, even-numbered sawtooth metal strips without waste are obtained. The main advantage is that when the teeth or grooves of the first surface of the upper or lower toothed cutter wheel become dull and unusable, only the surface needs to be replaced to continue production, which not only significantly reduces the cost of purchasing tools but also improves production efficiency.

[0019] This invention relates to the designer of a serrated metal strip forming device.

[0020] To enable your review committee to gain a better understanding of the purpose, features, and effects of this work, the following detailed description, along with accompanying diagrams, is provided:

[0021] Referring to Figures 1 to 3, this invention provides a serrated metal strip forming device, which includes:

[0022] An upper gear cutting wheel 20 is provided with a first surface A and a second surface B, and the edges of the first surface A and the second surface B are provided with a plurality of tooth profiles C and a plurality of tooth grooves D.

[0023] A lower gear cutting wheel 30 has a first surface A and a second surface B. The edges of the first surface A and the second surface B are surrounded by a plurality of tooth profiles C and a plurality of tooth grooves D. The tooth profile C of the upper gear cutting wheel 20 is aligned with the tooth groove D of the lower gear cutting wheel 30, and the tooth groove D of the upper gear cutting wheel 20 is aligned with the tooth profile C of the lower gear cutting wheel 30. Continuous metal strips are conveyed here and rolled by the upper and lower gear cutting wheels 20 and 30. The metal strips are cut along the center line to form two continuous serrated metal strips. After being rolled flat and cut to the appropriate length, even-numbered serrated metal strips 40A and 40B without waste are obtained (see Figures 4 to 7). When the tooth shape C or tooth groove D of the first face A of the upper toothed cutter wheel 20 or the lower toothed cutter wheel 30 becomes dull and unusable, it can be replaced with the second face B to continue production. This not only greatly reduces the cost of purchasing tools, but also improves production efficiency.

[0024] Referring to Figure 2, in the serrated metal strip forming device, a set of conveyor wheels 50 is provided in front of the upper toothed cutter wheel 20 and the lower toothed cutter wheel 30 to the continuous metal strip entry position.

[0025] Referring to Figure 2, in the serrated metal strip forming device, a chamfering device 60 is provided in front of the conveyor wheel group 50, in front of the upper toothed cutter wheel 20 and the lower toothed cutter wheel 30, so that the continuous metal strip can be chamfered.

[0026] Referring to Figure 2, in the serrated metal strip forming device, a leveling device 70 is provided behind the upper toothed cutter wheel 20 and the lower toothed cutter wheel 30, and the two continuous serrated metal strips are leveled by the leveling device 70.

[0027] Referring to Figure 2, the serrated metal strip forming device includes a cutting device 80 located behind the leveling device 70. After the two continuous serrated metal strips are leveled, they pass through the cutting device 80, which cuts the two continuous serrated metal strips according to the required length, making them into an even number of finished serrated metal strips 40A and 40B.

[0028] Referring to Figure 3, in the aforementioned sawtooth metal strip forming device, a flat pad 21 and a flat pad 31 are respectively provided below the upper toothed cutter wheel 20 and above the lower toothed cutter wheel 30.

[0029] In the aforementioned sawtooth metal strip forming device, a cylindrical or cylindrical pad may be respectively provided below the upper toothed cutter wheel 20 and above the lower toothed cutter wheel 30.

[0030] Referring to Figures 4 to 7, the lengths (H) of the serrated metal strips 40A and 40B are variable and can be adjusted according to customer needs. This adjustment is achieved simply by speeding up or slowing down the cutting device 80, thus shortening or lengthening the length (H) of the serrated metal strips 40A and 40B. The length adjustment is quite convenient and quick. Furthermore, the width of the continuous metal strip is (2W), which is twice the width of the continuous metal strip, while the width of the finished serrated metal strips 40A and 40B to the center line is (W). Therefore, cutting the continuous metal strip into two finished serrated metal strips 40A and 40B results in no waste, saving 10% of materials, reducing costs, and enhancing market competitiveness. The upper and lower toothed cutting wheels 20 and 30 continuously cut the serrated metal strips 40A and 40B without needing to descend or reset, saving descent or reset time and making production more efficient. The continuous metal strips enter through the chamfering device 60, are conveyed by the conveying wheel group 50 and rolled by the upper and lower toothed cutting wheels 20 and 30, are then leveled by the leveling device 70 and cut by the cutting device 80, thus forming even-numbered sawtooth metal strips 40A and 40B.

[0031] As can be seen from the above, the sawtooth metal strip forming device of this invention is indeed the first of its kind in the industry and meets the novelty requirements of a utility model patent. Its comprehensive innovative design meets the progress requirements of a utility model patent. When the upper and lower toothed cutter wheels produce even numbers of sawtooth metal strips without waste, and the first side of the upper or lower toothed cutter wheel becomes dull, production can continue by simply replacing it with the second side of the upper or lower toothed cutter wheel. This greatly improves work efficiency and reduces the cost of purchasing tools, making it more suitable for industrial use.

[0032] The foregoing description focuses on the preferred embodiments of this invention and their technical features; however, those skilled in the art can make changes and modifications to this invention without departing from its spirit and principles, and such changes and modifications should all be covered within the scope defined by the following claims.

[0033] In summary, this invention provides a serrated metal strip forming device, which has indeed achieved all the objectives of this invention. Furthermore, the spatial form of its combined structure has not been seen in similar products, nor has it been disclosed before the application, thus meeting the requirements of the Patent Law. Therefore, this application is filed in accordance with the law.
