Description

Technical Field

[0001] This utility model relates to a plate cutting machine composed of multiple short rails and suction cups, which can both meet the one-time scribing (marking) cutting of plates of different specifications (lengths) and ensure the quality of scribing (marking) cutting. It belongs to the field of plate cutting machine manufacturing. Background Technology

[0002] EP3415473B1, entitled "Sheet Metal Cutting System", comprises: a scribing slider; a longitudinal guide including a pair of opposing surfaces, the lower surface of which is adapted to face the sheet metal being processed, and the longitudinal guide including opposing upper surfaces equipped with a pair of parallel tracks adapted to be slidably coupled to the scribing slider; at least one suction cup coupled (e.g., rigidly engaged) to the lower surface of the longitudinal guide, preferably aligned in plan view with the lower (and upper) surfaces of the longitudinal guide itself, the suction cup being adapted to selectively adhere to the sheet metal (surface) and defining a substantially flat contact surface for the longitudinal guide on the sheet metal (surface), wherein the tracks are arranged on opposite sides relative to the median plane of the suction cup itself (parallel to the longitudinal axis of the longitudinal guide), and, for example, due to this solution, a better distribution of mechanical stress applied to the cutting system is achieved to eliminate or at least mitigate orientation variations of the longitudinal guide that may result in irregular scribing or damage to the surface of the sheet metal. Specifically, during the movement of the slab along the longitudinal guide, when longitudinal scribe lines are formed on the slab, the angular momentum on the longitudinal guide is released due to the pressure applied to the scribe line slider. In one embodiment of the invention, the track is parallel to the mid-plane of the suction cup, for example, parallel to the longitudinal axis of the longitudinal guide. In this way, an even better distribution of mechanical stress applied to the cutting system I is achieved. The clamping member includes a lever operable to switch the suction cup from a plate-clamping state to a stationary state where the suction cup releases the plate; in one embodiment of the invention, the lever of the clamping member is rotatable from an engaged position in the clamping state of the suction cup to a released position in the stationary state of the suction cup; thus, the lever has extremely limited resistance in the vertical direction (perpendicular to the lower surface) of the cutting system in both the engaged and released positions. In practice, due to this solution, the lever allows the slider to slide when the suction cup is clamped and when the suction cup is stationary, which is undoubtedly advantageous for the cutting operator. In one embodiment of this invention, the scribing slider includes at least two rollers, each adapted to rotate on one of a pair of tracks, a scribing component adapted to scribing a slab, and a slider body connected to the rollers and the scribing component. When the scribing slider is connected to the track via the rollers, the slider body defines an opening adapted to receive a lever of a clamping component in an engaged or released position during the sliding of the scribing slider along the longitudinal guide. This allows for free movement of the scribing slider along the longitudinal guide. The problem is that, 1. Due to the limitation of the longitudinal guide length, this slab cutting system cannot be used for one-time cutting of slabs exceeding the predetermined longitudinal guide length.For example: When the length of the longitudinal guide rail is less than the length of the material being cut, the material cannot be cut in one go. It requires splicing the cutting marks and making two or more cuts. However, these multiple splicing cuts cannot guarantee the consistency of the separated surfaces of the cut materials, resulting in a lack of seamless splicing between the materials. If a longer guide rail is used, the user needs to purchase longitudinal guide rails of different lengths (because the material lengths vary), increasing user costs and making them inconvenient to carry, thus failing to meet consumer needs. 2. When the suction cup is attached to the lower surface of the longitudinal guide rail, it means that the lower surface of the longitudinal guide rail is raised by the suction cup and cannot adhere to the material surface. At this time, when the scribe wheel is forcefully cutting the material, the downward pressure of the scribe slider handle causes the guide rail to deform to varying degrees depending on its distance from the suction cup. This uneven deformation directly results in inconsistent cutting force on the material, leading to broken lines and uneven cutting on the cut surface. This makes the material prone to uneven surfaces or breakage when it is broken after scribe (scribing). 3. Whether the rollers in the scribing (marking) slider slide horizontally or vertically along the track, they roll in an open manner along the track surface, rather than rolling along the track surface with clamps. Therefore, when the rollers jump while rolling forward, the scribing (marking) wheel will also jump. The jumping of the scribing (marking) wheel will inevitably cause the cutting surface of the board to be missed, which will affect the cutting quality, the quality of the board's cut surface, and the yield of the board's cut surface. Summary of the Invention

[0003] Design objective: To overcome the shortcomings of the prior art, design a plate cutting machine composed of multiple short rails and suction cups that can both meet the requirements of one-time scribing (marking) cutting of plates of different specifications (lengths) and ensure the quality of scribing (marking) cutting.

[0004] Design Scheme: To achieve the above design objectives, this utility model features the following structural design: 1. The longitudinal guide rail is composed of multiple rail segments of the same or different lengths, which are connected to the front and rear of the suction cup. The side-to-side connection of these multiple rail segments is one of the technical features of this utility model. The purpose of this design is as follows: Background Art EP3415473B1: The length of the longitudinal guide rail is predetermined by its design, meaning the length is a fixed value and cannot be changed during use. When the length of the plate being cut by scribing (marking) is greater than the length of the longitudinal guide rail, it cannot be cut in one go; it requires splicing the scribing (marking) cut. This makes it impossible to ensure the consistency of the separation surface of the cut plate, resulting in a lack of seamless splicing between plates. To solve this problem, this utility model designs the longitudinal guide rail as a segmented plug-in structure composed of multiple short rails, and the length of the short rails can be of various specifications. Theoretically, the length of the guide rail can be extended indefinitely through longitudinal plugging. In practice, it can be plugged into a longitudinal guide rail of the required length according to the length of the material being cut, thereby ensuring that the cutting wheel in the cutting device completes the scribing (marking) cut of the material in one go along the longitudinal guide rail, ensuring the consistency of the cut surface of the material being cut, and thus solving the technical problem that the background technology could not solve. 2. The design of the longitudinal sliding track formed by the embedded optical shafts in the top and bottom of the through grooves on both sides of the rail body is the second technical feature of this utility model. The purpose of this design is as follows: The roller disclosed in background technology EP3415473B1, whether installed horizontally or vertically, always has its concave arc surface rolling on the track surface. When there are impurities on the track surface, the roller will inevitably bounce on the track surface. This bounce will cause the driven scribing wheel (cutting wheel) to bounce, resulting in missed cuts on the cutting lines of the board. This missed cuts will cause the enamel on the cut surface of the board to chip off locally after the cutting is completed, thus affecting the cutting quality and the quality of the board. To solve this problem, this utility model replaces the roller with a U-groove bearing. Since the U-groove bearing has much lower fitting precision and rolling resistance than the roller, it not only has less resistance when moving along the track but also prevents deviation. Secondly, this utility model uses a track composed of double guide rails, forming a clamping fit between the double guide rails and the U-groove bearing surface. This prevents the U-groove bearing from passing through when there are impurities on the track surface, allowing passage only after the impurities are removed. This avoids the phenomenon of the cutting wheel missing cuts, thus preventing localized chipping of the enamel on the cut surface of the sheet metal and ensuring the quality of the cut surface. 3. The design of separating the lower part of the suction cup from the longitudinal guide rail is the third technical feature of this utility model. The purpose of this design is that, as disclosed in EP3415473B1, the suction cup is attached to the lower surface of the longitudinal guide rail, indicating that the lower surface of the longitudinal guide rail is raised by the suction cup and cannot adhere to the sheet metal surface. To maintain balance, EP3415473B1 uses a shim to solve this problem.However, the shims can only provide local support and cannot provide comprehensive support for the longitudinal guide rail. Therefore, when the scribing wheel applies force to scribing and cutting the plate, the guide rail between the shims will undergo different degrees of downward deformation due to the downward pressure of the scribing slider handle. This deformation directly causes inconsistent scribing and cutting force on the plate, resulting in inconsistent cutting force on the plate surface by the scribing wheel. This leads to a coexistence of incomplete and complete cuts on the plate. This coexistence inevitably causes uneven joints or breakage of the plate when it is broken after the scribing wheel. To solve this problem, this utility model features a clearance position on the rail body. This clearance position is used to prevent the suction cup body and the rubber base from contacting each other. In other words, the lower surface of the rail body opposite the suction cup is not in contact with the suction cup body and the rubber base. The rubber base and the lower surface of the rail body are on the same plane. When the suction cup attracts the surface of the board, the suction force generated by the suction cup forces the lower surface of the short rail into close contact with the board. Therefore, when the scribing wheel applies force downward to scribing and cutting the board, the scribing (marking) cutting force received by the board is consistent, ensuring that the cutting line of the board will not break or the cutting will not be uneven. This also ensures that when the board is broken after scribing (marking), the break surface will not be uneven or broken. 4. Replacing the vertical handle in EP3415473B1 with a lever-type downward pressing design is the fourth technical feature of this utility model. The purpose of this design is that, while the handle in EP3415473B1 uses vertical downward pressure to allow the scoring wheel to complete the scoring (scribing) cutting of the enamel on the surface of the board, it requires little effort and is difficult to control the downward pressure, this invention uses a lever-type downward pressure structure, which not only makes the downward pressure easier to control but also saves a lot of effort. For example, under the same scoring (scribing) conditions, this invention requires less than one-tenth the force of the prior art EP3415473B1.

[0005] Technical solution: A sheet metal cutting machine consisting of multiple short rails and a suction cup, including a longitudinal guide rail, a suction cup and a cutting device. The longitudinal guide rail is formed by the upper and lower parts of the two sides of the end faces of multiple rail sections of the same or different lengths being connected by optical axis to form a seamless sliding track of U-groove bearing in the cutting device. The middle of the multiple rail sections is connected to the front and back of the suction cup.

[0006] Compared with the prior art, this utility model has several advantages: First, it achieves a multi-segment rail body with a longitudinal extension structure that connects to multiple suction cups. This allows the rail length to be freely extended according to the length of the material being cut, while ensuring that the suction cups firmly adhere the guide rail to the surface of the material. This enables the scribing (marking) of any material length in a single operation, ensuring the consistency of the cut surface. Second, this utility model designs the multi-segment short rails as a clamping rail, achieving a clamping effect between the upper and lower short rails on the U-shaped groove shaft surface of the cutting device, thus overcoming the defects of the EP3415473B1 technology. Third, the design of separating the lower part of the suction cup from the longitudinal guide rail eliminates the defects of the EP3415473B1 technology, which uses pads to support the lower surface of the rail to compensate for the height gap between the rail and the suction cup. This ensures that the scribing cutting force received by the material surface is consistent, preventing broken lines and uneven cutting, and ensuring that the material does not have uneven cross-sections, chipping, or breakage when broken after scribing (marking).

Detailed Implementation

[0022] Example 1: Refer to Appendix Figure 1 and 15 A sheet metal cutting machine consisting of multiple short rails and a suction cup includes a longitudinal guide rail, a suction cup, and a cutting device. The longitudinal guide rail is formed by the upper and lower parts of the two sides of the end face of multiple rail bodies 1 of the same or different lengths being connected by optical shaft 1-1 to form a seamless sliding track of U-groove bearings 5-10 in the cutting device 3. The middle of the multiple rail bodies 1 is connected to the front and rear of the suction cup 2.

[0023] See attached document Figure 2 The guide rail 1 has a step 1-4 that mates with the groove 6-5-1 on the suction cup. The guide rail 1-1 mates with the guide rail 1-2. The rail body 1 has a clearance position 1-3, which is used to clear the suction cup body 6-5 and the rubber base 6-7. After the assembly is completed, the rail body 1 and the connecting piece 6-2 are spliced ​​by tightening the Torx nut 6-1.

[0024] See attached document Figure 2-7 The rail body 1 is connected to the suction cup 2 on the front and back, and the side of the rail body 1 is connected by an optical axis 1-1.

[0025] The rail body 1 has through grooves 1-6 on both sides. The top and bottom surfaces of the through grooves are respectively provided with through optical axis slots 1-2. Optical axes 1-1 are embedded in the through optical axis slots 1-2. The optical axes connect multiple sections of the rail body 1 into a whole to form a clamp-type U-groove bearing sliding rail. The exposed surfaces of the clamp-type U-groove bearing sliding rail slide with the U-groove bearing in the cutting device.

[0026] The through grooves on both sides of the track body 1 are seamlessly misaligned and connected. Figure 2 .

[0027] The end face of the rail body 1 is a profile-formed structure with through grooves 1-6 on both sides and a shaping support composed of an upper longitudinal opening and a lower longitudinal through cavity in the middle. The two walls of the upper longitudinal opening of the shaping support form a reverse top locking groove 1-5.

[0028] The multi-section rail body 1 has through grooves 1-6 on both sides connected by an optical axis 1-1, which clamps the suction cup 2 in the middle. The suction cup 2 is provided with an inverted T-shaped guide rail connector 6-2. The vertical rod of the inverted T-shaped guide rail connector 6-2 has T-shaped grooves 6-2-1 on both sides. The T-shaped grooves 6-2-1 and the through groove of the suction cup body 6-5 are inserted into each other. The plum nut 6-1 is screwed down and tightened against the bottom of the reverse top locking groove 1-5 to fix the T-shaped guide rail connector 6-2 and the reverse top locking groove 1-5 into one piece.

[0029] The rail body 1 is designed with a clearance position 1-3, which is used to clear the suction cup body 6-5 and the rubber base 6-7. The guide rail body 1 is designed with a step 1-4 that is inserted into the upper slot 6-5-1 of the suction cup 2.

[0030] Features of the short guide rail structure:

[0031] Track body 1 is composed of aluminum profiles and four optical axes 1-1 arranged in a relatively clamping track, such as... Figure 5-7 As shown, the optical axis 1-1 adopts a staggered distribution as follows: Figure 7 As shown, the staggered distribution is for two reasons: firstly, to better splice the guide rails, and secondly, to facilitate smooth sliding of the slider on the guide rails.

[0032] The rail body 1 is designed with a T-slot 1-5, which fits into the T-slot 6-2-1 of the guide rail connector 6-2 without clearance, ensuring a misaligned connection between the guide rails.

[0033] See attached document Figure 8The suction cup 2 is composed of a plum nut 6-1, a guide rail connector 6-2, a pin 6-3, a wrench 6-4, a suction cup body 6-5, a spring 6-6, and a rubber base 6-7. The bottom of the suction cup body 6-5 is disc-shaped. The mating surface between the suction cup body 6-5 and the rail body 1 is arc-shaped, and grooves 6-5-2 and slots 6-5-1 are sequentially opened from bottom to top on the arc-shaped surface. The bottom of the suction cup body 6-5, which is not mating with the rail body 1, has an arc-shaped boss 6-5-3. The non-matting surface of the suction cup body is a plane 6-5-4, and a channel 6-5-5 is formed between the plane 6-5-4 and the arc-shaped boss 6-5-3.

[0034] The guide rail connector 6-2 is designed with a T-slot 6-2-1 that matches the T-slot of the suction cup body 6-5, and a threaded hole 6-2-2 that connects to the plum nut 6-1. The rubber base 6-7 connects to the spring 6-6 and the suction cup body 6-5 via the guide rail connection 6-3-3, and is fixed to the suction cup body via the suction cup wrench 6-4 and the cylindrical pin 6-3.

[0035] See attached document Figure 15 In the cutting device 3, the lower part of both sides of the slide 5-12 is provided with square grooves 5-12-1, which cooperate with square nuts 5-13. The slider is designed with threaded holes 5-12-2, which cooperate with tightening screws 5-14. Tightening screws 5-14 tighten the square nuts 5-13. The height of the U-shaped groove bearings 5-10 can be adjusted by adjusting the tightness of the tightening screws 5-14 to ensure that the slider moves smoothly on the guide rail without gaps. The U-shaped groove bearings 5-10 are distributed in two rows, one in front and one behind, and the U-shaped groove bearings 5-10 are seamlessly cooperated with the optical axis 1-1 surface on the rail body.

[0036] In the cutting device 3, the handle 5-4 is longer than 20 cm. A cutter wheel 5-6 is installed on one side of the handle 5-4. The cutter wheel is installed on the handle 5-4 by screw 2 5-8. A side wheel 5-2 is installed on one side of the handle 5-4. The side wheel 5-2 is connected to the handle 5-4 by screw 1 5-1 and nut 5-3. The handle 5-4 is connected to the slide 5-12 by screw 5-7. The handle 5-4 is connected to the slide 5-12.

[0037] Features of the cutting device:

[0038] The U-groove bearings 5-10 on the slider of the cutting device 5 are arranged in two rows, upper and lower, and fit seamlessly with the round steel 1-1 on the rail body 1. The advantage of this is that it can ensure that the cutting system slides smoothly on the rail body 1 and improve the bending strength of the guide rail 1.

[0039] An extended handle 5-4 is used. A cutting wheel (blade) 5-6 is mounted on one side of the handle 5-4, and the blade is fixed to the handle 5-4 by screw 5-8. A side wheel 5-2 is mounted on the other side, and the side wheel 5-2 is connected to the handle 5-4 by screw 5-1 and nut 5-3. The handle 5-4 is connected to the slide 5-12 by screw 5-7. The handle 5-4 is extended and distributed with the slide block. The advantages are: even force distribution on both sides, easier cutting, and the ability to apply relatively large force to cut through the surface enamel of the board.

[0040] Multiple U-groove bearings 5-10 are installed on the slide 5-12. One type of U-groove bearing 5-10 is fixed to the slide 5-12 by a washer 5-9 and a screw 5-11, while the other type is fixed to the slider by a washer 5-9, a screw 5-11, and a square nut 5-13. The slider is designed with a square groove 5-12-1, which mates with the square nut 5-13. The slider is also designed with a threaded hole 5-12-2, which mates with a tightening screw 5-14. The tightening screw 5-14 tightens the square nut 5-13. The height of the U-groove bearing 5-10 is adjusted by adjusting the tightness of the tightening screw 5-14, ensuring that the slider moves smoothly and without gaps on the guide rail.

[0041] Spring 5-5 ensures that handle 5-4 can spring up freely.
