Description

Technical Field

[0001] This invention relates to an accessory specifically designed for sawing machines or sawing devices, and more specifically to a combination tooling for disc saw tail material and small-sized material. Background Technology

[0002] The following problems may occur when using a circular saw to cut steel plates:

[0003] Although the material is clamped by the clamping mechanism on the feeding platform for holding steel plates, it moves backward due to insufficient clamping friction.

[0004] When the saw reaches the tail section, the clamping mechanism on the feeding platform can no longer hold the steel plate because the size of the material becomes smaller (since both the clamping mechanism and the power head have a certain width, the clamping mechanism cannot hold the tail section).

[0005] Patent CN219274671U discloses a device for simultaneously processing circular saws with and without tail material. The device includes an inner machine platform and an outer machine platform, an inner hydraulic cylinder at one end of the inner machine platform, a rear clamping slider connected to the inner hydraulic cylinder at one end of the inner machine platform, an outer hydraulic cylinder at one end of the outer machine platform, a front clamping slider connected to the outer hydraulic cylinder at one end of the outer machine platform, a hydraulic cylinder bracket on the inner machine platform, an upper hydraulic cylinder on the hydraulic cylinder bracket, a longitudinal clamping block below the upper hydraulic cylinder, a lead screw passing through the outer machine platform, and a linear slide rail connecting the inner machine platform and the lead screw seat. The device drives a second jaw to move back and forth via a lead screw synchronous pulley, the lead screw, and a servo motor. When a profile has a tail material, the second jaw pulls it out for cutting; when there is no tail material, the second jaw and the first jaw work together, making it convenient to clamp the profile, preventing material waste, and improving production efficiency. However, the device has a complex structure and can only solve the problem of not being able to clamp the tail material. Summary of the Invention

[0006] The purpose of this invention is to overcome the defects in the prior art and provide a combined tooling for circular saw tail material and small-sized material. The tail material limiting tooling assembly can prevent the material from retreating due to insufficient clamping friction. The tail material pushing block tooling assembly or bridging tooling assembly can ensure that when the tail material is sawed, the clamping mechanism on the feeding platform for clamping the steel plate can still clamp the tail material.

[0007] To achieve the above objectives, the technical solution of this invention is to design a combined tooling for circular saw tail material and small-sized materials, comprising a tail material limiting tooling assembly, a tail material pushing block tooling assembly, and a bridging tooling assembly. The tail material limiting tooling assembly prevents material backing due to insufficient clamping friction. The tail material pushing block tooling assembly or the bridging tooling assembly ensures that when sawing reaches the tail material, the clamping mechanism on the feeding platform for holding the steel plate can still hold the tail material.

[0008] A further technical solution is that the tail material limiting tooling assembly consists of a vertically set rectangular plate, two limiting pins installed at the lower end of the rectangular plate, bolt holes set on a vertical surface of the rectangular plate, and adjusting bolts that are compatible with the bolt holes;

[0009] The tail material pusher tooling assembly consists of a pair of components. Each component consists of a cuboid pusher and a cuboid limiting block connected to the pusher by two bolts. The two bolts are located at the same position along the length of the pusher and are arranged side by side. The length of the limiting block is the same as the width of the pusher.

[0010] The bridge erection tooling assembly consists of a pressure plate, a handle fixedly connected to the pressure plate, an adjustment bolt installed under the pressure plate, and a stop bolt for the tail material. The pressure plate is provided with threaded holes that match the adjustment bolts, and the pressure plate is also provided with threaded holes that match the stop bolts. The stop bolts are spaced apart from the side of the pressure plate away from the handle. The highest limit position of the adjustment bolts is lower than that of the stop bolts.

[0011] First, place the plate (i.e., the steel plate to be sawed), then clamp it (using the clamping mechanism on the feeding platform of the circular saw). Install this support (i.e., the tail material limiting fixture assembly) (the clamping mechanism has a hole that matches the limiting pin of the tail material limiting fixture assembly). The support (i.e., the tail material limiting fixture assembly) plays a limiting role (the adjusting bolt on the rectangular plate of the tail material limiting fixture assembly abuts against the side of the steel plate to be sawed away from the circular saw blade, i.e., the side of the tail material of the steel plate to be sawed; the adjusting bolt improves the applicability of this fixture assembly, and for steel plates of a certain size, there is no need to adjust the installation position of this fixture assembly), preventing the material from retreating due to insufficient clamping friction.

[0012] When the tail material is too small to be clamped, the operator holds the handle of the bridging tool, the pressure plate presses on the upper surface of the tail material, and the abutment bolt abuts against the side of the tail material, and then moves closer to the circular saw to cut the small-sized material or tail material; the pressure plate presses down and the abutment bolt abuts against the side to achieve effective clamping of the tail material.

[0013] When the tail material is too small to be clamped, two push blocks (equivalent to "outstretched fingers") are installed on the worktable of the clamping mechanism via limit blocks. That is, the lower surface of the push blocks contacts the upper surface of the worktable, while the limit blocks abut against the side of the worktable facing the tail material to be sawed. When the worktable moves forward, it is equivalent to extending the width of the worktable, so that the tail material can be pushed mechanically towards the power head and finally sawed by the circular saw blade on the power head.

[0014] A further technical solution is to have two bolt holes and two adjusting bolts;

[0015] The pressure plate in the bridge erection tooling assembly is the rectangular plate in the tail material limiting tooling assembly. The upper surface of the pressure plate is provided with bolt holes for installing the length adjustment bolts. The side of the pressure plate furthest from the handle is provided with two limiting pins as the tail material limiting tooling assembly.

[0016] A further technical solution is that the pressure plate in the bridge erecting tooling assembly, i.e. the cuboid push block in the tail material push block tooling assembly, has a blind hole-shaped threaded hole on the limiting block that matches the height adjustment bolt; the length of the limiting block is the same as the width of the push block.

[0017] This configuration allows the pressure plate in the post-bridging tooling assembly to function as both a cuboid pusher in the tail material pusher tooling assembly and a rectangular plate in the tail material limiting tooling assembly. Furthermore, this configuration allows the post-bridging tooling assembly to function as both a tail material limiting tooling assembly and a tail material pusher tooling assembly. It can be used as a tail material pusher tooling assembly or a bridging tooling assembly after the two tail material limiting tooling assemblies on the clamping mechanism are removed. First, this combined tooling is used as a tail material limiting tooling component to prevent the material from retreating due to insufficient clamping friction. When the tail material is reached, if it cannot be clamped, the tail material limiting tooling component is pulled out and then used as a bridging tooling component to "bridge" the tail material, pressing it down and pushing it forward to power the sawing head. Alternatively, the limiting block is installed on the end of the height adjustment bolt that protrudes from the handle, and then the limiting block is installed on the worktable of the clamping mechanism. That is, the lower surface of the push block (or pressure plate) (more precisely, the lower surface of the length adjustment bolt on the pressure plate) contacts the upper surface of the worktable, while the limiting block rests against the side of the worktable facing the tail material to be sawed. In this case, the handle extends outward to push the tail material. With this configuration, this combined tooling greatly saves the parts originally required by three toolings, integrating three toolings into one. It can be used rationally according to different working conditions to achieve the desired effect of the corresponding tooling. The design is ingenious, reduces costs, and minimizes the footprint.

[0018] A further technical solution is to have one bolt hole and one adjusting bolt;

[0019] 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; the side of the pressure plate away from the handle is provided with two limiting pins as the tail material limiting tooling assembly.

[0020] The tail material limiting fixture assembly is the tail material pusher fixture assembly; the tail material limiting fixture assembly consists of an insert plate whose length is larger than the width of the steel plate to be sawed, an insertion hole on the fixing back of the clamping mechanism on the feeding platform, and an insertion hole on the pressure plate of the clamping mechanism on the feeding platform.

[0021] 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 installed on the fixed backing and pressure plate of the clamping mechanism. The simple pressing mechanism consists of a base fixedly connected to the fixed backing or pressure plate of the clamping mechanism, a hydraulic cylinder fixedly installed on the base, and a folded pressure plate fixedly connected to the exposed end of the piston rod of the hydraulic cylinder.

[0022] The insert plate is rectangular. The folded pressure plate in the simplified pressing mechanism can further reduce the size of the fixed support and pressure plate. The folded pressure plate can effectively extend the pressing coverage area, or in other words, even if the tail material protrudes far from the clamping mechanism, it can still be pressed down by the simplified pressing mechanism from above. The folded pressure plate in the simplified pressing mechanism can be an L-shaped folded pressure plate. In this case, the vertical section of the folded pressure plate is located directly below the hydraulic cylinder of the simplified pressing mechanism, while the horizontal section extends beyond the hydraulic cylinder. Only the horizontal section of the folded pressure plate needs to press down the part of the tail material that is far from the power head to achieve the function of pressing down the tail material. The insertion holes on the fixed support of the clamping mechanism and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform are all compatible with the insert plate. When the last piece of material is cut, insert the insert plate into the hole on the fixed backing plate and pressure plate of the clamping mechanism. In this way, the insert plate is located on the side of the tail material away from the power head and abuts against the side 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 pressing mechanism on the circular saw (or by adding a simplified pressing mechanism), the combination of pushing and pressing actions eliminates the need for a clamping mechanism (or simplifies its structure: only the fixed support of the original clamping mechanism is needed, and the moving parts of the original clamping mechanism are replaced with pressure plates, thus minimizing the height or thickness of the pressure plates, and also minimizing the width and thickness of the fixed support (only needing to be slightly thicker than the steel plate to be sawed). This minimizes interference with the power head's movement and extends the distance the clamping mechanism can move towards the power head; the pressure plate of the clamping mechanism presses down on the tail material from the side, combined with the folded pressure plate of the simplified pressing mechanism). The combination of pushing and pressing (pressing includes both upward and side pressing actions) facilitates the feeding of tail material and small-sized pieces, making sawing easier. The clamping mechanism consists of a fixed support, a pressure plate slidably mounted on the feeding platform, and a hydraulic cylinder mounted on one side of the pressure plate. The hydraulic cylinder is fixedly connected to the feeding platform, and the exposed end of the hydraulic cylinder's piston rod is fixedly connected to the pressure plate.

[0023] The bridging tooling assembly consists of several rubber strips fixedly mounted on the worktable of the clamping mechanism, with the rubber strips extending out of the worktable.

[0024] The tail material limiting fixture assembly is the tail material pusher fixture assembly; the tail material limiting fixture assembly consists of an insert plate whose length is larger than the width of the steel plate to be sawed, an insertion hole on the fixing back of the clamping mechanism on the feeding platform, and an insertion hole on the pressure plate of the clamping mechanism on the feeding platform; the insert plate is a folded insert plate with an L-shaped cross section, the horizontal section of the insert plate is located above the tail material, and the vertical section of the insert plate is located behind the tail material.

[0025] The cross-sections of the insertion holes on the fixed backrest of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform are all L-shaped, and the width of their vertical sections matches the width of the vertical section of the insertion plate. The length of the vertical section of the insertion holes on the fixed backrest of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform is greater than the length of the vertical section of the insertion plate. The length of the horizontal section of the insertion holes on the fixed backrest of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform matches the length of the horizontal section of the insertion plate. The height of the horizontal section of the insertion holes on the fixed backrest of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform is greater than the height of the horizontal section of the insertion plate.

[0026] The bridging tooling assembly consists of several rubber strips fixedly mounted on the worktable of the clamping mechanism, with the rubber strips extending out of the worktable.

[0027] The insertion holes on the fixed back of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform are rectangular holes with a size larger than that of the insertion plate; a triangular prism-shaped sponge is fixedly installed on the side of the vertical section of the insertion plate away from the power head, and the larger end of the triangular prism-shaped sponge is set close to the pressure plate of the clamping mechanism on the feeding platform.

[0028] The advantages and beneficial effects of this invention are as follows: the tail material limiting fixture assembly can avoid the situation where the material retreats due to insufficient clamping friction; the tail material pushing block fixture assembly or bridging fixture assembly can ensure that when the tail material is sawn, the clamping mechanism on the feeding platform for clamping the steel plate can still clamp the tail material.

[0029] This modular tooling greatly reduces the number of components required by the original three tooling units. It integrates the three tooling units together and makes reasonable use of them according to different working conditions to achieve the desired effect. The design is ingenious, reduces costs, and minimizes the footprint.

[0030] By utilizing the existing pressing mechanism on the circular saw (or by adding a simple pressing 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 support of the original clamping mechanism is needed, and the moving parts of the original clamping mechanism are replaced with pressure plates. In this way, the height or thickness of the pressure plate can be reduced as much as possible, and the width and thickness of the fixed support can also be reduced as much as possible {just make sure it is slightly thicker than the steel plate to be cut}. This can minimize interference with the movement of the power head and extend the distance that the clamping mechanism moves towards the power head; the pressure plate of the clamping mechanism presses down on the tail material from the side, and the folded pressure plate of the simple pressing mechanism also presses down on the tail material). With the combination of pushing and pressing (pressing includes both upward and side pressing actions), the tail material and small-sized materials are fed, which facilitates sawing.

[0031] The clamping mechanism uses pressure plates to hold the tail material from the side and top. The combination of pushing and pressing (pressing includes both upward and side pressing) allows for the feeding of tail materials and small-sized pieces, facilitating sawing. This design further simplifies the structure of the tooling assembly, reduces the number of components required, lowers the cost, and reduces the space occupied.

[0032] Before clamping, there is no need to adjust the position of the steel plate to be sawed by using the insert plate as a reference. After clamping the steel plate to be sawed, insert the insert plate so that the vertical section of the insert plate abuts against the end face of the tail material and the horizontal section of the insert plate presses against the upper surface of the tail material. Then continue to move the insert plate towards the fixed backing direction of the clamping mechanism on the feeding platform until it can no longer move. Attached Figure Description

[0066] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0067] Example 1: As Figures 1 to 11 As shown, the present invention is a combined tooling for circular saw tail material and small-sized material, which consists of a tail material limiting tooling assembly, a tail material pushing block tooling assembly, and a bridging tooling assembly;

[0068] The tail material limiting fixture assembly consists of a vertically set rectangular plate 1, two limiting pins 2 installed at the lower end of the rectangular plate, bolt holes on a vertical surface of the rectangular plate, and adjusting bolts 3 that are compatible with the bolt holes;

[0069] The tail material pusher tooling assembly consists of a pair of components. Each component consists of a cuboid pusher 4 and a cuboid limiting block 6 connected to the pusher by two bolts 5. The two bolts are located at the same position along the length of the pusher and are arranged side by side. The length of the limiting block is the same as the width of the pusher.

[0070] The bridge erection tooling assembly consists of a pressure plate 7, a handle 8 fixedly connected to the pressure plate, an adjustment bolt 9 set under the pressure plate, and a retaining bolt 10 for the tail material. The pressure plate is provided with threaded holes that match the adjustment bolts, and the pressure plate is also provided with threaded holes that match the retaining bolts. The retaining bolts are spaced apart from the side of the pressure plate away from the handle. The highest limit position of the adjustment bolts is lower than that of the retaining bolts.

[0071] Example 2: The difference from Example 1 is that, as shown in Example 2... Figure 14 , Figure 15 As shown (because the combined tooling serves as different tooling components under different operating conditions, the limit block 6 is sometimes not installed, therefore...) Figure 14 The diagram is an exploded view. When this assembly tooling is used as a tail material pusher tooling component, the limiting block 6 is installed to the end of the height adjustment bolt 9 that protrudes from the handle. There are two bolt holes and two length adjustment bolts.

[0072] The pressure plate 7 in the bridge erecting tooling assembly is the rectangular plate in the tail material limiting tooling assembly. The upper surface of the pressure plate is provided with bolt holes for installing the length adjusting bolts 3. The side of the pressure plate furthest from the handle 8 is provided with two limiting pins 2 as the tail material limiting tooling assembly.

[0073] Here, the upper surface of the pressure plate refers to the side of the pressure plate that contacts the handle; this setting of the rear bridge tooling assembly is still a tail material limiting tooling assembly. First, this assembly of tooling is used as a tail material limiting tooling assembly (e.g. Figure 16 As shown, to ensure the effectiveness of the adjusting bolt, even when the adjusting bolt is extended to its shortest length, its end still exceeds the handle and is closest to the tail material. This prevents the material from retreating due to insufficient clamping friction. If the tail material cannot be clamped, the tail material limiting fixture assembly is pulled out and then used as a bridging fixture assembly to "bridge" the tail material, pressing it down and pushing it forward to power the sawing head. Of course, since the upper surface of the pressure plate is under pressure (because the bridging fixture assembly pushes the tail material against the bolt and the lower surface of the pressure plate 7 during operation, while 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 adjusting bolt nut to prevent damage to the adjusting bolt or the upper clamping mechanism.

[0074] The pressure plate 7 in the bridge erection tooling assembly is a cuboid pusher block in the tail material pusher block tooling assembly. The limit block 6 is provided with a blind hole-shaped threaded hole that matches the height adjustment bolt 9. The length of the limit block is the same as the width of the pusher block.

[0075] This configuration of the pressure plate in the post-bridging tooling assembly serves as both the cuboid pusher in the tail material pusher tooling assembly and the rectangular plate in the tail material limiting tooling assembly. The post-bridging tooling assembly functions as both a tail material limiting tooling assembly and a tail material pusher tooling assembly. By removing the two tail material limiting tooling assemblies on the clamping mechanism, it can be used as either a tail material pusher tooling assembly or a bridging tooling assembly. Initially, this tooling assembly is used as a tail material limiting tooling assembly to prevent material from retreating due to insufficient clamping friction. When the tail material is reached, it cannot be clamped. At this point, the tail material limiting tooling assembly is removed, and the assembly is then used as a bridging tooling assembly to achieve "bridging" (e.g., ...). Figure 18 As shown), the tail material is pressed down and pushed forward to power the sawing head for cutting; or the limiting block 6 is installed on the worktable of the clamping mechanism after the end of the height adjustment bolt 9 protrudes from the handle, that is, the lower surface of the push block (or pressure plate 7) (more precisely, the lower surface of the length adjustment bolt 3 on the pressure plate 7) is in contact with the upper surface of the worktable, while the limiting block 6 abuts against the side of the worktable facing the tail material to be cut. At this time, the handle 8, as the extended part, pushes the tail material (such as...) Figure 17 (As shown). This configuration greatly reduces the number of components required for the original three tooling units. By integrating the three tooling units together, the desired effects can be achieved by making reasonable use of them according to different working conditions. The design is ingenious, reduces costs, and minimizes floor space.

[0076] Example 3: The difference from Example 2 is that, as shown in Example 3... Figure 19 As shown, there is one bolt hole and one adjusting bolt;

[0077] 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 limiting pins 2 as the tail material limiting tooling assembly.

[0078] This configuration makes the post-bridging tooling assembly still function as the tail material limiting tooling assembly. However, compared to the previous solution, the height adjustment bolts in the bridging tooling assembly are directly used as length adjustment bolts in the tail material limiting tooling assembly. This reduces the number of bolts and threaded holes on the entire assembly, making the overall structure simpler and reducing costs. This assembly can be used as the tail material limiting tooling assembly initially (e.g., Figure 20 As shown), to prevent the material from retreating due to insufficient clamping friction, and to prevent the tail material from being clamped when it reaches the end, the tail material limiting tooling component is pulled out and then used as a bridging tooling component to achieve "bridging", pressing down the tail material and pushing it forward to provide power head sawing.

[0079] Furthermore, this tooling assembly can also serve as a component for a tail material pusher. See [link / reference]. Figure 21As shown, the tooling assembly is flipped over and placed on the workbench, with the upper surface of the pressure plate and the side end of the handle abutting against the upper surface and side of the workbench, respectively.

[0080] Example 4: The difference from Example 1 is that, as shown in Example 4... Figures 22 to 26 As shown, the tail material limiting fixture assembly is the tail material pusher fixture assembly; the tail material limiting fixture assembly consists of an insert plate 11 whose length is larger than the width of the steel plate to be cut (because in general the length direction of the steel plate to be cut is consistent with the length direction of the feeding platform 12), an insertion hole on the fixing backing 13 of the clamping mechanism on the feeding platform, and an insertion hole on the pressure plate 14 of the clamping mechanism on the feeding platform.

[0081] 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 installed on the fixed backing 13 of the clamping mechanism and the pressure plate 14 of the clamping mechanism. The simple pressing mechanism consists of a base 15 fixedly connected to the fixed backing or the pressure plate of the clamping mechanism, a hydraulic cylinder 16 fixedly installed on the base, and a folded pressure plate 17 fixedly connected to the exposed end of the piston rod of the hydraulic cylinder.

[0082] The insert plate is rectangular. The folded pressure plate in the simplified pressing mechanism can further reduce the size of the fixed support and pressure plate. The folded pressure plate can effectively extend the pressing coverage area, or even if the tail material protrudes far from the clamping mechanism, it can still be pressed down from above by the simplified pressing mechanism. The folded pressure plate in the simplified pressing mechanism can be an L-shaped folded pressure plate. In this case, the vertical section of the folded pressure plate is located directly below the hydraulic cylinder of the simplified pressing mechanism, while the horizontal section extends beyond the hydraulic cylinder. Only the horizontal section of the folded pressure plate needs to press down the part of the tail material away from the power head to achieve the function of pressing down the tail material (a better solution is to integrally or fixedly install a horizontal plate extending towards the middle of the tail material on the side of the horizontal section of the L-shaped folded pressure plate. The horizontal plate is perpendicular to the horizontal section of the L-shaped folded pressure plate, so that the pressing range is larger and the pressing stability is further improved). The insertion holes on the fixed support of the clamping mechanism and the insertion holes on the pressure plate of the clamping mechanism on the feeding platform are all adapted to the insert plate. When the last piece of material is cut, insert the insert plate into the hole on the fixed backing and pressure plate of the clamping mechanism (that is, the insert plate is not initially inserted into the hole; more accurately, before clamping, adjust the position of the steel plate to be cut, then insert the insert plate, adjust the steel plate to be cut so that it abuts against the insert plate, then pull out the insert plate, and the clamping mechanism holds it until the last piece of material is cut). In this way, the insert plate 11 is located on the side end of the last piece of material away from the power head, abutting against the side end of the last piece of material, forming a last piece of material limiting tooling assembly, which prevents the last piece of material from retreating due to insufficient friction in the clamping mechanism. By utilizing the existing pressing mechanism on the circular saw (or by adding a simple pressing mechanism), the combination of pushing and pressing actions eliminates the need for a clamping mechanism (or simplifies its structure: only the fixed support of the original clamping mechanism is needed, and the moving parts of the original clamping mechanism are replaced with pressure plates, so the height or thickness of the pressure plates can be minimized, and the width and thickness of the fixed support can also be minimized {only needing to be slightly thicker than the steel plate to be cut}. This minimizes interference with the power head's movement and extends the distance the clamping mechanism can move towards the power head (after clamping the steel plate to be cut, the clamping mechanism moves towards the power head driven by the screw and nut mechanism on the feeding platform); the pressure plate of the clamping mechanism presses down on the tail material from the side, combined with the folded pressure plate of the simple pressing mechanism pressing down on the tail material). With the combination of pushing and pressing (pressing includes both upward and side pressing actions), the tail material and small-sized materials are fed, facilitating sawing. The clamping mechanism consists of a fixed backing 13, a clamping plate 14 slidably mounted on the feeding platform, and a hydraulic cylinder mounted on one side of the clamping 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 clamping plate.The tail material limiting fixture assembly is also the tail material pushing fixture assembly. When the clamping mechanism is driven to move by the screw and nut mechanism of the feeding platform, the tail material is pushed towards the power head through the insert plate. (Due to the setting of the folded pressure plate and the pressure plate of the clamping mechanism, the insert plate can be set closer together, which is equivalent to moving the tail material closer to the power head. Therefore, this combination fixture further reduces the required parts, reduces costs, and reduces the space occupied by the fixture.)

[0083] The bridging tooling assembly consists of several rubber strips 18 fixedly mounted on the worktable of the clamping mechanism, with the rubber strips extending out of the worktable.

[0084] Since the rubber strip is set on the worktable, that is, on the lower surface of the tail material, and the rubber strip extends out of the worktable, it is equivalent to extending the maximum distance of the clamping mechanism. Even if the power head cuts the rubber strip, it is not a problem because its hardness is much less than that of the steel plate. Moreover, the power head will only be close to the clamping mechanism when cutting the tail material. Therefore, the rubber strip, as a bridging tooling component, not only supports the part of the tail material that extends out of the clamping mechanism, but also works with the tail material pusher tooling component to extend the tail material further to facilitate cutting by the power head.

[0085] Example 5: The difference from Example 4 is that, as Figures 27 to 29 As shown ( Figure 27 (Equivalent to a top view of a circular saw) The tail material limiting tooling assembly can also be equipped with a simple pressing mechanism without matching it, and the tail material is pressed down by the insert plate itself; the insert plate is a folded insert plate 11 with an L-shaped cross section, the horizontal section of the insert plate is located above the tail material, and the vertical section of the insert plate is located behind the tail material, which plays the role of limiting and pushing the tail material; the insert holes on the fixing back 13 of the clamping mechanism on the feeding platform and the insert holes on the pressure plate 14 of the clamping mechanism on the feeding platform are both L-shaped in cross section, and the width of their vertical sections is adapted to the width of the vertical section of the insert plate 11, the feeding platform The length of the vertical section of the insertion hole on the fixed support 13 of the clamping mechanism on the platform and the insertion hole on the pressure plate 14 of the clamping mechanism on the feeding platform is greater than the length of the vertical section of the insertion plate. The length of the horizontal section of the insertion hole on the fixed support 13 of the clamping mechanism on the feeding platform and the insertion hole on the pressure plate 14 of the clamping mechanism on the feeding platform is adapted to the length of the horizontal section of the insertion plate. The height of the horizontal section of the insertion hole on the fixed support 13 of the clamping mechanism on the feeding platform and the insertion hole on the pressure plate 14 of the clamping mechanism on the feeding platform is greater than the height of the horizontal section of the insertion plate.

[0086] The length of the vertical section of the insert plate is less than the thickness of the smallest specification of the steel plate to be sawed. With this setting, when there is still some tail material left after sawing, the insert plate is inserted into the insertion hole on the fixed backing and pressure plate of the clamping mechanism (that is, the insert plate is not initially inserted into the insertion hole; more accurately, the position of the steel plate to be sawed is adjusted before clamping, then the insert plate is inserted, the steel plate to be sawed is adjusted to abut against the insert plate, then the insert plate is pulled out, the clamping mechanism holds it, and the insert plate is inserted again when there is tail material). In this way, the insert plate 11 is located at the side end of the tail material away from the power head and abuts against the side end 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. Due to the size of the insertion hole, the insertion plate can be placed above the tail material when it is inserted. Then, the tail material is pressed down by its own weight (the horizontal section of the insertion plate), while the vertical section of the insertion plate limits the movement and pushes the tail material. By combining the pushing and pressing actions, the clamping mechanism can be eliminated (or the structure of the clamping mechanism can be simplified: only the fixed support of the original clamping mechanism is needed, and the moving parts of the original clamping mechanism are replaced with pressure plates. In this way, the height or thickness of the pressure plate can be reduced as much as possible, and the width and thickness of the fixed support can also be reduced as much as possible {it only needs to be slightly thicker than the steel plate to be sawed}. This can minimize interference with the movement of the power head and extend the distance that the clamping mechanism can move towards the power head (after clamping the steel plate to be sawed, the clamping mechanism moves towards the power head after being driven by the screw and nut mechanism on the feeding platform); the tail material is pressed down from the side and top by the pressure plate of the clamping mechanism). With the combination of the pushing and pressing actions (pressing includes both upward and side pressing actions), the tail material and small-sized materials can be fed, which is convenient for sawing. This configuration further simplifies the structure of the tooling assembly, reduces the number of components required, lowers the cost of the tooling assembly, and reduces the space occupied by the tooling assembly.

[0087] A better technical solution is: such as Figures 30 to 32 As shown, the insertion holes on the fixed support 13 of the clamping mechanism on the feeding platform and the insertion holes on the pressure plate 14 of the clamping mechanism on the feeding platform are rectangular holes with a size larger than that of the insertion plate 11 (a triangular prism-shaped sponge is fixedly installed on the side of the vertical section of the insertion 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, it is not necessary to adjust the position of the steel plate to be sawed before clamping, using the insertion plate as a reference. After clamping the steel plate to be sawed, the insertion plate is inserted so that the vertical section of the insertion plate abuts against the end face of the tail material and the horizontal section of the insertion plate presses against the upper surface of the tail material. Then, the insertion plate is moved towards the fixed support 13 of the clamping mechanism on the feeding platform until it can no longer move (indicating that the sponge is fully compressed).

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
