Description

Technical Field

[0001] The invention relates to an accessory device specially suitable for a sawing machine or a sawing device, in particular to a combined tooling for circular saw tail materials and small-sized materials. Background Art

[0002] When using a circular saw to cut steel plates, the following problems may occur: Although the material is clamped by the clamping mechanism on the feeding platform for clamping the steel plate, the material retreats due to insufficient clamping friction; When the saw reaches the tailings, the material size becomes smaller and the clamping mechanism on the feeding platform for clamping the steel plate cannot clamp it (because the clamping mechanism and the power head themselves have a certain width, so the clamping mechanism cannot clamp it when it reaches the tailings).

[0003] Patent publication number N219274671U: A circular saw machine capable of processing both tailings and no tailings simultaneously, comprising an inner and outer machine table, an inner oil cylinder disposed at one end of the inner machine table, a rear clamping slide disposed at one end of the inner machine table and connected to the inner oil cylinder, an outer oil cylinder disposed at one end of the outer machine table, a front clamping slide disposed at one end of the outer machine table and connected to the outer oil cylinder, a cylinder bracket disposed on the inner machine table, an upper oil cylinder disposed on the cylinder bracket, a longitudinal clamping block disposed below the upper oil cylinder, a screw rod passing through the outer machine table, and a linear slide connected between the inner machine table and the material drawing screw rod seat. The second jaw is driven back and forth by a screw rod synchronous pulley, a screw rod, and a servo motor. When a profile has a head, the second jaw pulls out the head for cutting. When there is no head, the second jaw is used in combination with the first jaw, making it convenient for the device to clamp the profile, avoiding material waste and improving production efficiency. However, the device has a complex structure and can only solve the problem of a single tail material being unable to be clamped. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects existing in the prior art and provide a combined tooling for circular saw tailings and small-sized materials. The tailing limiting tooling assembly can avoid the material from retreating due to insufficient clamping friction. The tailing pushing block tooling assembly or the bridging tooling assembly can ensure that when the tailing is sawed, the clamping mechanism for clamping the steel plate on the feeding platform can still clamp the tailing.

[0005] To achieve the above objectives, the present invention provides a combined fixture for circular sawing of scrap and small-sized materials, comprising a scrap limiting fixture assembly, a scrap pushing block fixture assembly, and a bridging fixture assembly. The scrap limiting fixture assembly prevents the material from slipping back due to insufficient clamping friction, while the scrap pushing block fixture assembly and the bridging fixture assembly ensure that the clamping mechanism on the feed platform, which is used to clamp the steel plate, can still grasp the scrap when the scrap is cut.

[0006] A further technical solution is that the tail material limiting tooling assembly is composed of a vertically arranged rectangular plate, two limiting pins installed at the lower end of the rectangular plate, a bolt hole provided on a vertical surface of the rectangular plate, and a length-adjusting bolt adapted to the bolt hole; The tail material push block tooling assembly consists of a pair of components, each component consisting of a rectangular push block and a rectangular limit block connected to the push block by two bolts; the two bolts are located in parallel at the same position along the length direction of the push block, and the length of the limit block is consistent with the width of the push block; The bridge erection tooling assembly consists of a pressure plate, a handle fixedly connected to the pressure plate, a height adjustment bolt arranged under the pressure plate, and a support bolt for the tail material; a threaded hole adapted to the height adjustment bolt is arranged on the pressure plate, and a threaded hole adapted to the support bolt is also arranged on the pressure plate, and the support bolt is spaced apart from the side of the pressure plate away from the handle; the highest limit position of the height adjustment bolt is lower than the support bolt.

[0007] First place the plate (that is, the steel plate to be sawed), then clamp it (through the clamping mechanism for clamping the steel plate on the feeding platform of the circular saw), install the backrest (that is, the tail material limiting fixture assembly) (the clamping mechanism is provided with a socket that is compatible with the limiting pin of the tail material limiting fixture assembly), the backrest (that is, the tail material limiting fixture assembly) plays a limiting role (the length adjustment bolt on the rectangular plate of the tail material limiting fixture assembly rests on the side of the steel plate to be sawed away from the circular saw blade, that is, the side of the tail of the steel plate to be sawed; the length adjustment bolt improves the applicability of this fixture assembly, and the steel plates to be sawed within a certain range of sizes do not need to adjust the installation position of this fixture assembly), to prevent the material from moving backward due to insufficient clamping friction.

[0008] When the tailings cannot be clamped due to their small size, the handle of the bridging tool is manually held, the pressure plate is pressed on the upper surface of the tailings, and the abutment bolts are pressed against the side of the tailings, and then the circular saw is moved closer to achieve the sawing of small-sized materials or tailings; the pressure plate is pressed down and the abutment bolts are pressed against each other to achieve effective clamping of the tailings.

[0009] When the tailings cannot be clamped due to their small size, two push blocks (equivalent to "extended fingers") are installed on the work surface of the clamping mechanism through limit blocks, that is, the lower surface of the push blocks contacts the upper surface of the work surface, and the limit blocks rest against the side of the work surface facing the tailings to be sawed. At this time, when the work surface moves forward again, it is equivalent to extending the width of the work surface, so the tailings can be pushed mechanically to the power head and finally cut by the circular saw blade on the power head.

[0010] A further technical solution is that two bolt holes are provided and two length adjustment bolts are also provided; The pressure plate in the bridging tooling assembly is the rectangular plate in the tail material limiting tooling assembly, and the upper surface of the pressure plate is provided with the bolt hole for installing the length adjustment bolt; the side of the pressure plate farthest from the handle is provided with two limit pins serving as the tail material limiting tooling assembly.

[0011] A further technical solution is that the pressure plate in the bridge tooling assembly is the rectangular push block in the tail material push block tooling assembly, and a blind hole-shaped threaded hole adapted to the height adjustment bolt is provided on the limit block; the length of the limit block is consistent with the width of the push block.

[0012] In this way, the pressure plate in the rear bridge tooling assembly is both the rectangular push block in the tail material pushing block tooling assembly and the rectangular plate in the tail material limiting tooling assembly; in this way, the rear bridge tooling assembly is both the tail material limiting tooling assembly and the tail material pushing block tooling assembly, and the two tail material limiting tooling assemblies set on the clamping mechanism are pulled out and then used as a tail material pushing block tooling assembly or as a bridge tooling assembly. First, this combined tooling is used as a tail material limiting tooling component to prevent the material from moving backward due to insufficient clamping friction. When the tail material is not clamped, the tail material limiting tooling component is pulled out, and then used as a bridging tooling component to achieve "bridging", pressing the tail material and pushing it forward to allow the power head to saw; or after the limit block is installed to the end of the height adjustment bolt where the handle is exposed, it is installed on the work surface of the clamping mechanism through the limit block, that is, the lower surface of the push block (or pressure plate) (more accurately, the lower surface of the length adjustment bolt on the pressure plate) contacts the upper surface of the work surface, and the limit block rests on the side of the work surface facing the tail material to be sawed, and the handle is used as the extended part to push the tail material. After this setting, this combined tooling greatly saves the components required for the original three toolings, integrates the three toolings together, and reasonably utilizes them according to different working conditions to achieve the required effects of the corresponding tooling. The design is ingenious, reduces costs and reduces space.

[0013] A further technical solution is that there is one bolt hole and one length adjustment bolt; The pressure plate in the bridging tooling assembly is the rectangular plate in the tail material limiting tooling assembly, and the height adjustment bolt in the bridging tooling assembly is the length adjustment bolt in the tail material limiting tooling assembly; two limit pins serving as the tail material limiting tooling assembly are provided on the side of the pressure plate away from the handle.

[0014] The tail material limiting tooling assembly is the tail material pushing block tooling assembly; the tail material limiting tooling assembly is composed of a plug plate whose length is greater than the width of the steel plate to be sawed, a socket on the fixed backrest of the clamping mechanism on the feeding platform, and a socket on the pressure plate of the clamping mechanism on the feeding platform.

[0015] A simple pressing mechanism is provided in conjunction with the tail material limiting tooling assembly. Two simple pressing mechanisms are provided and are respectively fixedly mounted on the fixed backer and the pressure plate of the clamping mechanism. The simple pressing mechanism is composed of a base fixedly connected to the fixed backer or the pressure plate of the clamping mechanism, a hydraulic cylinder fixedly provided on the base, and a folded pressure plate fixedly connected to the exposed end of the piston rod of the hydraulic cylinder.

[0016] The insert plate is a rectangular plate; the provision of a folding plate in the simple downward pressing mechanism can further reduce the size of the fixed backing and the pressing plate, and the folding plate can effectively extend the coverage of the downward pressing, or even if the tailings extend a lot beyond the clamping mechanism, they can still be pressed from above by the simple downward pressing mechanism; the folding plate in the simple downward pressing mechanism can be an L-shaped folding plate in cross section, such that the vertical section of the folding plate is located directly below the hydraulic cylinder of the simple downward pressing mechanism, while the horizontal section extends beyond the hydraulic cylinder. The horizontal section of the folding plate only needs to press the portion of the tailings away from the power head to achieve the effect of pressing the tailings down. The sockets on the fixed backing of the clamping mechanism and the sockets on the pressing plate of the clamping mechanism on the feeding platform are both compatible with the insert plate. When there is still some tail material left at the end of sawing, insert the insert plate from the fixed support of the clamping mechanism and the insert plate on the pressure plate, so that the insert plate is located at the side end face of the tail material away from the power head and rests on the side end face of the tail material, forming a tail material limiting tooling assembly to prevent the tail material from retreating due to insufficient friction of the clamping mechanism. By utilizing the existing downward pressure mechanism on the circular saw (or by providing an additional simplified downward pressure mechanism), the combination of pushing and pressing actions eliminates the need for a clamping mechanism (or simplifies the structure of the clamping mechanism: only the fixed backing of the original clamping mechanism is required, and the original movable part of the clamping mechanism is replaced with a pressure plate. This allows the height or thickness of the pressure plate to be minimized, and the width and thickness of the fixed backing can also be minimized (just ensuring it is slightly thicker than the steel plate to be cut). This minimizes interference with the movement of the power head and extends the distance the clamping mechanism can move toward the power head. The pressure plate of the clamping mechanism presses the tail stock from the side, combined with the folded pressure plate of the simplified downward pressure mechanism). By combining pushing and pressing (pressing includes both upward and side pressure), the feeding of tail stock and small-sized stock is achieved, facilitating sawing. The clamping mechanism consists of a fixed backing, a pressure plate slidably mounted on the feed platform, and a hydraulic cylinder mounted on one side of the pressure plate. The hydraulic cylinder is fixedly connected to the feed platform, and the exposed end of the hydraulic cylinder piston rod is fixedly connected to the pressure plate.

[0017] The bridge erection tooling assembly is composed of a plurality of rubber strips fixedly arranged on the working surface of the clamping mechanism, and the rubber strips extend out of the working surface of the clamping mechanism.

[0018] The tail material limiting tooling assembly is the tail material pushing block tooling assembly; the tail material limiting tooling assembly is composed of a plug plate whose length is greater than the width of the steel plate to be sawed, a socket on the fixed backrest of the clamping mechanism on the feeding platform, and a socket on the pressure plate of the clamping mechanism on the feeding platform; the plug plate is a folded plug plate with an L-shaped cross-section, the horizontal section of the plug plate is located above the tail material, and the vertical section of the plug plate is located behind the tail material.

[0019] The cross-sections of the sockets on the fixed support of the clamping mechanism on the feeding platform and the sockets on the pressure plate of the clamping mechanism on the feeding platform are both L-shaped, and the width of their vertical sections matches the width of the vertical section of the insertion plate. The lengths of the vertical sections of the sockets on the fixed support of the clamping mechanism on the feeding platform and the sockets on the pressure plate of the clamping mechanism on the feeding platform are greater than the length of the vertical section of the insertion plate. The lengths of the horizontal sections of the sockets on the fixed support of the clamping mechanism on the feeding platform and the sockets on the pressure plate of the clamping mechanism on the feeding platform match the length of the horizontal section of the insertion plate. The heights of the horizontal sections of the sockets on the fixed support of the clamping mechanism on the feeding platform and the sockets on the pressure plate of the clamping mechanism on the feeding platform are greater than the height of the horizontal section of the insertion plate. The bridge erection tooling assembly is composed of a plurality of rubber strips fixedly arranged on the working surface of the clamping mechanism, and the rubber strips extend out of the working surface of the clamping mechanism.

[0020] The sockets on the fixed backrest of the clamping mechanism on the feeding platform and the sockets on the pressure plate of the clamping mechanism on the feeding platform are rectangular holes whose size is larger than the size of the plug plate; a triangular prism-shaped sponge is fixedly set on the side of the vertical section of the plug plate away from the power head, and the large-size end of the triangular prism-shaped sponge is set close to the pressure plate of the clamping mechanism on the feeding platform.

[0021] The advantages and beneficial effects of the present invention are that the tail material limiting tooling assembly can avoid the situation where the material retreats due to insufficient clamping friction, and the tail material pushing block tooling assembly or the bridging tooling assembly can ensure that when the tail material is sawed, the clamping mechanism for clamping the steel plate on the feeding platform can still clamp the tail material.

[0022] This combined tooling greatly saves the parts originally required for the three toolings, integrates the three toolings together, and rationally utilizes them according to different working conditions to achieve the effects required by the corresponding tooling. The design is ingenious, reduces costs and reduces space occupied.

[0023] By utilizing the existing downward pressure mechanism on the circular saw (or additionally setting up a simple downward pressure mechanism), through the combination of pushing and pressing, the clamping mechanism can be eliminated (or the structure of the clamping mechanism can be simplified: only the fixed backing of the original clamping mechanism is required, and the movable part of the original clamping mechanism is changed to a pressure plate, so that the height or thickness of the pressure plate can be reduced as much as possible, and the width and thickness of the fixed backing can also be reduced as much as possible {just ensure that it is slightly thicker than the steel plate to be sawed}, so that the interference with the power head movement can be minimized, and the distance that the clamping mechanism moves toward the power head can be extended; the tail material is pressed from the side by the pressure plate of the clamping mechanism, and the tail material is pressed upward by the folding pressure plate of the simple downward pressure mechanism). With the combination of pushing and pressing (pressing includes upper pressing and side pressing), the feeding of tail materials and small-sized materials is realized, which is convenient for sawing.

[0024] The clamping mechanism's pressure plates hold the tailings from the sides and top, combining pushing and pressing (both upward and sideways) to facilitate the feeding of tailings and small pieces, facilitating sawing. This arrangement further simplifies the structure of the combined tooling, reducing the number of components, lowering its cost, and reducing its footprint.

[0025] Before clamping, there is no need to use the insert plate as a reference to adjust the position of the steel plate to be sawed. After clamping the steel plate to be sawed, the insert plate is inserted so that the vertical section of the insert plate is against the side end surface of the tail material and the horizontal section of the insert plate is pressed against the upper surface of the tail material. Then, the insert plate is continued to be moved toward the fixed support direction of the clamping mechanism on the feeding platform until it can no longer move. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] Example 1: Figures 1 to 11 As shown, the present invention is a combined tooling for circular saw tailings and small-sized materials, which is composed of a tailing limiting tooling assembly, a tailing pushing block tooling assembly and a bridging tooling assembly; The tail material limiting fixture assembly consists of a vertically arranged rectangular plate 1, two limiting pins 2 installed at the lower end of the rectangular plate, a bolt hole set on a vertical surface of the rectangular plate, and a length adjustment bolt 3 adapted to the bolt hole; The tailing push block assembly consists of a pair of components, each of which consists of a rectangular push block 4 and a rectangular limit block 6 connected to the push block by two bolts 5; the two bolts are located in parallel at the same position in the length direction of the push block, and the length of the limit block is consistent with the width of the push block; The bridge erection tooling assembly consists of a pressure plate 7, a handle 8 fixedly connected to the pressure plate, a height adjustment bolt 9 arranged under the pressure plate, and a support bolt 10 for the tail material; a threaded hole adapted to the height adjustment bolt is arranged on the pressure plate, and a threaded hole adapted to the support bolt is also arranged on the pressure plate, and the support bolt is spaced apart from the side of the pressure plate away from the handle; the highest limit position of the height adjustment bolt is lower than the support bolt.

[0029] Example 2: The difference from Example 1 is that Figure 14 、 Figure 15 As shown (because the combined tooling is used as different tooling components under different working conditions, the limit block 6 is sometimes not installed, so Figure 14The figure is an exploded view. When the combined tooling is used as a tail material push block tooling assembly, the limit block 6 is installed to the end of the height adjustment bolt 9 that is exposed to the handle). There are two bolt holes and two length adjustment bolts. The pressure plate 7 in the bridging tooling assembly is a rectangular plate in the tail material limiting tooling assembly, and the upper surface of the pressure plate is provided with the bolt hole for installing the length adjustment bolt 3; the side of the pressure plate farthest from the handle 8 is provided with two limit pins 2 as the tail material limiting tooling assembly.

[0030] Here, the upper surface of the pressing plate refers to the side where the pressing plate contacts the handle; in this way, the rear bridge fixture assembly or the tail material limiting fixture assembly is set up. First, use this combined fixture as the tail material limiting fixture assembly (such as Figure 16 As shown, to ensure the effect of the lengthening bolt, the end of the lengthening bolt still exceeds the end of the handle closest to the tailing when it is extended to the shortest point, so as to prevent the material from moving backward due to insufficient clamping friction. When the tailing is reached, the tailing limit fixture assembly cannot be clamped, and then the tailing limit fixture assembly is pulled out to "bridge" the tailing, pressing it and pushing it forward for the power head to saw. Of course, since the upper surface of the pressure plate is under pressure (because the bridging fixture assembly pushes the tailing by abutting the bolt and the lower surface of the pressure plate 7 when working, and the pressure is on the upper surface of the pressure plate 7), a better solution is to fix a rubber sleeve on the top of the nut of the lengthening bolt to avoid damage to the lengthening bolt or the upper pressure clamping mechanism.

[0031] The pressure plate 7 in the bridging tooling assembly is the rectangular push block in the tail material push block tooling assembly, and the limit block 6 is provided with a blind hole-shaped threaded hole adapted to the height adjustment bolt 9; the length of the limit block is consistent with the width of the push block.

[0032] In this way, the pressure plate in the rear bridging fixture assembly is both the rectangular push block in the tail material pushing block fixture assembly and the rectangular plate in the tail material limiting fixture assembly; in this way, the rear bridging fixture assembly is both the tail material limiting fixture assembly and the tail material pushing block fixture assembly. After the two tail material limiting fixture assemblies set on the clamping mechanism are pulled out, they can be used as tail material pushing block fixture assemblies or as bridging fixture assemblies. First, this combined fixture is used as a tail material limiting fixture assembly to prevent the material from retreating due to insufficient clamping friction. When the tail material is not clamped, the tail material limiting fixture assembly is pulled out and then used as a bridging fixture assembly to achieve "bridging" (such as Figure 18 As shown), press the tail material and push it forward to cut the power head; or after the limit block 6 is installed to the end of the height adjustment bolt 9 exposed to the handle, it is installed on the work surface of the clamping mechanism through the limit block, that is, the lower surface of the push block (or pressure plate 7) (more accurately, the lower surface of the length adjustment bolt 3 on the pressure plate 7) is in contact with the upper surface of the work surface, and the limit block 6 is against the side of the work surface facing the tail material to be sawed, at this time, the handle 8 is used as the extended part to push the tail material (as shown). Figure 17As shown). This configuration greatly saves the parts required for the original three tools. The three tools are integrated together and can be reasonably used according to different working conditions to achieve the desired effect of the corresponding tool. The design is ingenious, reduces costs and reduces space.

[0033] Example 3: The difference from Example 2 is that Figure 19 As shown, there is one bolt hole and one length adjustment bolt; The pressure plate 7 in the bridging tooling assembly is the rectangular plate in the tail material limiting tooling assembly, and the height adjustment bolt 9 in the bridging tooling assembly is the length adjustment bolt in the tail material limiting tooling assembly; the side of the pressure plate away from the handle 8 is provided with two limit pins 2 serving as the tail material limiting tooling assembly.

[0034] In this way, the rear bridge fixture assembly is still a tail material limiting fixture assembly, but compared with the previous solution, the height adjustment bolts in the bridge fixture assembly are directly used as the length adjustment bolts in the tail material limiting fixture assembly, reducing the number of bolts and threaded holes on the entire combined fixture, making the structure of the entire combined fixture simpler and the cost lowered. First, this combined fixture is used as a tail material limiting fixture assembly (such as Figure 20 As shown in the figure), the material is prevented from moving backward due to insufficient clamping friction. When the tail material cannot be clamped, the tail material limiting fixture assembly is pulled out and then used as a bridging fixture assembly to achieve "bridging", pressing the tail material and pushing it forward for the power head to saw.

[0035] And this combined tooling can also be used as a tailing push block tooling component. Figure 21 As shown, the combined tool is directly turned over and placed on the work surface, with the upper surface of the pressing plate and the side end surface of the handle respectively resting against the upper surface and side surface of the work surface.

[0036] Example 4: The difference from Example 1 is that Figures 22 to 26 As shown, the tail material limiting fixture assembly is the tail material pushing block fixture assembly; the tail material limiting fixture assembly is composed of an insert plate 11 whose length is greater than the width of the steel plate to be sawed (because generally the length direction of the steel plate to be sawed is consistent with the length direction of the feeding platform 12), a socket on the fixed backrest 13 of the clamping mechanism on the feeding platform, and a socket on the pressure plate 14 of the clamping mechanism on the feeding platform.

[0037] A simple pressing mechanism is provided in conjunction with the tail material limiting tooling assembly. Two simple pressing mechanisms can be provided, which are respectively fixedly mounted on the fixed backer 13 of the clamping mechanism and the pressure plate 14 of the clamping mechanism; the simple pressing mechanism is composed of a base 15 fixedly connected to the fixed backer of the clamping mechanism or the pressure plate of the clamping mechanism, a hydraulic cylinder 16 fixedly provided on the base, and a folded pressure plate 17 fixedly connected to the exposed end of the piston rod of the hydraulic cylinder.

[0038] The insert plate is a rectangular plate; the setting of the folding pressure plate in the simple downward pressing mechanism can further reduce the size of the fixed backing and the pressure plate, and the folding pressure plate can effectively extend the coverage of the downward pressure, or even if the tail material extends a lot from the clamping mechanism, it can still be pressed from above by the simple downward pressing mechanism; the folding pressure plate in the simple downward pressing mechanism can be a folding pressure plate with an L-shaped cross-section, so that the vertical section of the folding pressure plate is located directly below the hydraulic cylinder of the simple downward pressing mechanism, while the horizontal section exceeds the hydraulic cylinder. Only the horizontal section of the folding pressure plate needs to press the part of the tail material away from the power head to play the role of pressing the tail material down (a better solution is: a horizontal plate extending toward the middle of the tail material is also integrally or fixedly provided on the side of the horizontal section of the L-shaped folding pressure plate, and the horizontal plate is perpendicular to the horizontal section of the folding pressure plate with an L-shaped cross-section, so that the downward pressure range is larger, further improving the stability of the downward pressure). The socket on the fixed backing of the clamping mechanism and the socket on the pressure plate of the clamping mechanism on the feeding platform are both compatible with the insert plate. When there is still some scrap left at the end of sawing, the insert plate is inserted from the fixed support of the clamping mechanism and the socket on the pressure plate (that is, the insert plate is not inserted into the socket at the beginning. A more accurate approach is to adjust the position of the steel plate to be sawed before clamping, then insert the insert plate, adjust the steel plate to be sawed to abut against the insert plate, then pull out the insert plate, clamp it with the clamping mechanism, and insert the insert plate until there is no scrap left). In this way, the insert plate 11 is located at the side end face of the scrap away from the power head and abuts against the side end face of the scrap, forming a scrap limiting tooling assembly to prevent the scrap from retreating due to insufficient friction of the clamping mechanism. By utilizing the existing downward pressure mechanism on the circular saw (or additionally setting up a simple downward pressure mechanism), through the combination of pushing and pressing, the clamping mechanism can be eliminated (or the structure of the clamping mechanism can be simplified: only the fixed backing of the original clamping mechanism is required, and the movable part of the original clamping mechanism is changed to a pressure plate, so that the height or thickness of the pressure plate can be reduced as much as possible, and the width and thickness of the fixed backing can also be reduced as much as possible {just ensure that it is slightly thicker than the steel plate to be sawed}, so that the interference with the power head action can be minimized, and the distance that the clamping mechanism moves toward the power head can be extended (after the clamping mechanism clamps the steel plate to be sawed, it is driven by the screw nut mechanism on the feeding platform and moves toward the power head); the tail material is pressed from the side by the pressure plate of the clamping mechanism, and the tail material is pressed by the folding pressure plate of the simple downward pressure mechanism). Under the combination of pushing and pressing (pressing includes two actions: upward pressure and side pressure), the feeding of tail materials and small-sized materials is realized, which is convenient for sawing. The clamping mechanism is composed of a fixed backer 13, a clamping mechanism pressure plate 14 slidingly arranged on the feeding platform, and a hydraulic cylinder arranged on one side of the pressure plate. The hydraulic cylinder is fixedly connected to the feeding platform, and the exposed end of the piston rod of the hydraulic cylinder is fixedly connected to the pressure plate.The tail material limiting tooling assembly is also a tail material pushing block tooling assembly. When the clamping mechanism is driven by the screw nut mechanism of the feeding platform to move, the tail material is pushed toward the power head through the insert plate (due to the setting of the folding pressure plate and the pressure plate of the clamping mechanism, the insert plate can be set closer, so it is equivalent to bringing the tail material closer to the power head. Therefore, this combined tooling further reduces the required components, reduces costs, and reduces the space occupied by tooling).

[0039] The bridge fixture assembly is composed of a plurality of rubber strips 18 fixedly arranged on the working surface of the clamping mechanism, and the rubber strips extend out of the working surface of the clamping mechanism.

[0040] Since the rubber strip is set on the work surface, that is, at the lower surface of the tail material, and the rubber strip is extended out of the work surface, it is equivalent to extending the maximum distance of the clamping mechanism. Even if the power head cuts the rubber strip, it does not matter because its hardness is much smaller than that of the steel plate. Moreover, the power head is close to the clamping mechanism only when cutting the tail material. Therefore, the rubber strip serves as a bridging tooling component. On the one hand, it plays the role of supporting the part of the tail material extending out of the clamping mechanism. It can also cooperate with the tail material push block tooling component to extend the tail material further for the power head to cut.

[0041] Example 5: The difference from Example 4 is that Figures 27 to 29 As shown ( Figure 27 The cutting board 11 is an L-shaped folding cutting board 11, and the horizontal section of the cutting board is located above the cutting board, and the vertical section of the cutting board is located behind the cutting board to limit and push the cutting board; the cross-section of the cutting board 11 is L-shaped, and the width of the vertical section of the cutting board 11 is adapted to the width of the cutting board 11. The length of the vertical section of the socket on the fixed backrest 13 of the clamping mechanism on the platform and the socket on the pressure plate 14 of the clamping mechanism on the feeding platform is greater than the length of the vertical section of the insert plate, the length of the horizontal section of the socket on the fixed backrest 13 of the clamping mechanism on the feeding platform and the socket on the pressure plate 14 of the clamping mechanism on the feeding platform is adapted to the length of the horizontal section of the insert plate, and the height of the horizontal section of the socket on the fixed backrest 13 of the clamping mechanism on the feeding platform and the socket on the pressure plate 14 of the clamping mechanism on the feeding platform is greater than the height of the horizontal section of the insert plate.

[0042] The length of the vertical section of the insert plate is less than the thickness of the minimum specification of the steel plate to be sawed. After this setting, when there is still scrap left at the end of sawing, the insert plate is inserted from the fixed backrest of the clamping mechanism and the insertion hole on the pressure plate (that is, the insert plate is not inserted into the insertion hole at the beginning. A more accurate approach is to adjust the position of the steel plate to be sawed before clamping, then insert the insert plate, adjust the steel plate to be sawed to abut against the insert plate, then pull out the insert plate, clamp it with the clamping mechanism, and insert the insert plate until there is scrap left). In this way, the insert plate 11 is located at the side end face of the scrap away from the power head and abuts against the side end face of the scrap, forming a scrap limiting tooling assembly to prevent the scrap from retreating due to insufficient friction of the clamping mechanism. Due to the setting of the socket size, the insert plate can be placed above the tail material when inserting the insert plate, and then the tail material can be pressed down by its own weight (the horizontal section of the insert plate), while the vertical section of the insert plate limits the position on the one hand and pushes the tail material on the other hand; through the combination of pushing and pressing, the clamping mechanism is eliminated (or the structure of the clamping mechanism is simplified: only the fixed backing of the original clamping mechanism is required, and the movable part of the original clamping mechanism is changed to a pressure plate, so that the height or thickness of the pressure plate can be reduced as much as possible, and the width and thickness of the fixed backing can also be reduced as much as possible {just ensure that it is slightly thicker than the steel plate to be sawed}, so that the interference with the power head action can be minimized, and the distance that the clamping mechanism moves toward the power head can be extended (after the clamping mechanism clamps the steel plate to be sawed, it is driven by the screw nut mechanism on the feeding platform and moves toward the power head); the tail material is pressed from the side and top by the pressure plate of the clamping mechanism). Under the combination of pushing and pressing (pressing includes two actions: upward pressure and side pressure), the feeding of tail materials and small-sized materials is realized, which is convenient for sawing. After such arrangement, the structure of the combined tooling is further simplified, the components required for the combined tooling are reduced, the cost of the combined tooling is reduced, and the space occupied by the combined tooling is reduced.

[0043] A better technical solution is: Figures 30 to 32 As shown, the sockets on the fixed backer 13 of the clamping mechanism on the feeding platform and the sockets on the pressure plate 14 of the clamping mechanism on the feeding platform are rectangular holes with a size larger than the size of the inserting plate 11 (a triangular prism-shaped sponge is fixedly set on the side of the vertical section of the inserting plate away from the power head and the large-size end of the triangular prism-shaped sponge 18 is set close to the pressure plate 14 of the clamping mechanism on the feeding platform). In this way, there is no need to use the inserting plate as a reference to adjust the position of the steel plate to be sawed before clamping. After clamping the steel plate to be sawed, the inserting plate is inserted so that the vertical section of the inserting plate is against the side end face of the tail material and the horizontal section of the inserting plate is pressed on the upper surface of the tail material. Then, the inserting plate is continued to be moved toward the fixed backer 13 of the clamping mechanism on the feeding platform until it can no longer move (indicating that the sponge is fully squeezed).

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
