Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, specifically to an inclined metal shearing machine equipped with a blade changing device. Background Technology

[0002] A metal shearing machine is a metal shearing and processing equipment. Its working principle is that, under hydraulic drive, the shearing head of the shearing machine cuts the metal. Under the action of strong shearing force, the metal is cut into sheared metal materials of a certain specification. After being processed by downstream equipment, suitable finished metal materials such as steel, aluminum, and copper can be obtained.

[0003] During metal shearing, the shearing machine blades withstand enormous shearing forces, requiring them to be securely attached to the machine. However, traditional simple gantry shears, due to their flawed structural design, often suffer from insufficient blade support or difficulties in disassembly and replacement. This disassembly and replacement process consumes significant manpower and resources, resulting in substantial maintenance and repair work, prolonged downtime, and wasted production capacity. Therefore, efficiently achieving rapid disassembly and replacement of metal shearing machine blades, shortening maintenance and repair time, and enhancing the shearing capacity of the blades through rational structural design to increase the production capacity of the metal shearing equipment become crucial. Utility Model Content

[0009] The tool changing device further includes a drive cylinder, which drives the movable track to reciprocate along its length, thereby aligning the first upper tool track and the first lower tool track with the upper tool changing edge and the lower tool changing edge; or, aligning the second upper tool track and the second lower tool track with the upper tool changing edge and the lower tool changing edge.

[0010] Furthermore, the upper blade assembly includes an upper blade, an upper blade groove for receiving the upper blade, and a first connecting screw for fixing the upper blade and the upper blade groove.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The implementation methods of this utility model will now be described based on its overall structure.

[0040] like Figures 1 to 8 As shown, this utility model discloses a tilting metal shearing machine equipped with a blade changing device, comprising:

[0041] A gantry frame 1 has an inlet 11 and an outlet 12. The gantry frame 1 is inclined and the inlet 11 is higher than the outlet 12. The top of the inner cavity of the gantry frame 1 has a shearing cylinder 13. The output end of the shearing cylinder 13 is connected to an upper blade assembly 14 that can reciprocate along the height direction of the gantry frame 1. A lower blade assembly 15 is also installed at the bottom of the inner cavity of the gantry frame 1.

[0042] Tool changing device 2, the tool changing device 2 is located on one side of the gantry frame 1, and the side of the gantry frame 1 facing the tool changing device 2 has an upper tool changing port 16 and a lower tool changing port 17;

[0043] The tool changing device 2 has a movable track 21 parallel to the gantry frame 1. A first bracket 211 and a second bracket 212 are installed on the movable track 21 along its length. A first upper tool track 221 and a first lower tool track 222 are installed side by side on the first bracket 211. A second upper tool track 231 and a second lower tool track 232 are installed side by side on the second bracket 212. On the other side of the movable track 21 opposite to the gantry frame 1, an upper tool replacement cylinder 241 and a lower tool replacement cylinder 242 are also provided. The upper tool replacement cylinder 241 and the lower tool replacement cylinder 242 can be aligned and extended to the upper tool changing port 16 and the lower tool changing port 17, and are connected to the upper tool assembly 14 and the lower tool assembly 15.

[0044] The tool changing device 2 further includes a drive cylinder 25, which drives the movable track 21 to reciprocate along its length, thereby aligning the first upper tool track 221 and the first lower tool track 222 with the upper tool changing edge 16 and the lower tool changing edge 17; or, aligning the second upper tool track 231 and the second lower tool track 232 with the upper tool changing edge 16 and the lower tool changing edge 17.

[0045] With the above structure, the metal shearing machine of this application adopts an inclined gantry frame 1 structure, with the inlet 11 higher than the outlet 12, allowing the metal material to slide smoothly into the inner cavity of the gantry frame 1 under the action of gravity for shearing, thereby improving the automation level of feeding and the ability to operate continuously. A shearing cylinder 13 is installed inside the gantry frame 1, driving the upper blade assembly 14 to reciprocate along the height direction of the gantry frame 1. A fixed lower blade assembly 15 is installed at the bottom, and the upper blade assembly 14 and the lower blade assembly 15 cooperate to complete the metal shearing action.

[0046] The tool changing device 2 is located on one side of the gantry frame 1. It connects with the upper tool assembly 14 and lower tool assembly 15 inside the gantry frame 1 via preset upper and lower tool changing ports 16 and 17. The movable track 21 of the tool changing device 2 is equipped with a first bracket 211 and a second bracket 212, each with its corresponding upper and lower tool tracks mounted side-by-side for storing different upper tool assemblies 14 and / or lower tool assemblies 15. The drive cylinder 25 moves the movable track 21 reciprocally along its length, precisely aligning the upper and lower tool tracks on the first bracket 211 or the second bracket 212 with the upper and lower tool changing ports 16 and 17. Simultaneously, the upper tool replacement cylinder 241 and lower tool replacement cylinder 242 are located on the other side of the gantry frame 1, aligning with and extending into the upper and lower tool changing ports 16 and 17 to complete the tool ejection and installation process. The upper tool assembly 14 and the lower tool assembly 15 can be changed synchronously and quickly in actual operation, reducing downtime caused by tool wear and greatly improving the continuity of operation and work efficiency.

[0047] Specifically, in the inclined metal shearing machine equipped with the blade changing device 2 described in this utility model, during the blade changing operation, the upper blade assembly 14 to be installed is pre-placed on the second upper blade track 231, and the lower blade assembly 15 to be installed is pre-placed on the second lower blade track 232. The drive cylinder 25 controls the movement of the movable track 21, so that the first upper blade track 221 is aligned with the upper blade changing port 16, and the first lower blade track 222 is aligned with the lower blade changing port 17. At the same time, the upper blade assembly 14 is lowered to the upper blade changing port 16 under the control of the shearing cylinder 13. The upper blade replacement cylinder 241 extends and passes through the first upper blade track 221 until it can connect with the upper blade assembly 14. The lower blade replacement cylinder 242 extends and passes through the first lower blade track 222 until it can connect with the lower blade assembly 15. The upper blade replacement cylinder 241 and the lower blade replacement cylinder 242 pull out the connected upper blade assembly 14 and lower blade assembly 15 respectively. After the upper blade assembly 14 is placed in the first upper blade track 221, the upper blade replacement cylinder 241 disconnects from the upper blade assembly 14. After the lower blade assembly 15 is placed in the first lower blade track 222, the lower blade replacement cylinder 242 disconnects from the lower blade assembly 15. The drive cylinder 25 controls the movement of the movable track 21 again, aligning the second upper cutter track 231 with the upper cutter changer 16 and the second lower cutter track 232 with the lower cutter changer 17. At this time, the upper cutter replacement cylinder 241 connects to the upper cutter assembly 14 to be installed on the second upper cutter track 231, and the lower cutter replacement cylinder 242 connects to the lower cutter assembly 15 to be installed on the second lower cutter track 232. The upper cutter replacement cylinder 241 pushes the upper cutter assembly 14 to be installed into the gantry 1 and connects and fixes the upper cutter assembly 14 to the output end of the shearing cylinder 13. The lower cutter replacement cylinder 242 pushes the lower cutter assembly 15 to be installed into the gantry 1 and connects and fixes the lower cutter assembly 15 to the bottom of the gantry 1, thus completing the cutter replacement. By using the cutter replacement device 2, the tool replacement cycle of the metal shearing machine is shortened, the workload is reduced, the operation difficulty is lowered, the maintenance efficiency of the metal shearing machine is improved, and the equipment capacity is increased.

[0048] Specifically, the upper blade assembly 14 includes an upper blade 141, an upper blade groove 142, a first connecting screw 143, a first limiting block 144, a first wedge-shaped washer 145, and a first hydraulic nut 146. The upper blade 141 is a rectangular high-strength alloy steel blade with at least one shearing edge. The upper blade groove 142 has a groove structure matching the shape of the upper blade 141 and is fixed below the output end of the shearing cylinder 13. The upper blade groove 142 has a positioning slot for installing the limiting block. The first limiting block 144 is embedded in the groove on the side of the upper blade 141 facing the upper blade groove 142, and simultaneously inserted into the corresponding positioning slot of the upper blade groove 142, thereby restricting the movement of the upper blade 141 in the horizontal and vertical directions and achieving accurate initial positioning. On the other side of the upper blade 141, a first wedge-shaped washer 145 is embedded. The cross-section of the first wedge-shaped washer 145 is wedge-shaped, and its wedge angle matches the tail end of the connecting screw. During installation, the first connecting screw 143 passes through the first wedge-shaped washer 145, the upper blade 141, the first limiting block 144, and the upper blade groove 142 in sequence, finally connecting and fixing the entire upper blade assembly 14 to the output end of the shearing cylinder 13. The end of the first connecting screw 143 away from the upper blade 141 is fastened by a first hydraulic nut 146. The hydraulic nut can output a stable and strong locking force through hydraulic principle, replacing the traditional mechanical nut and effectively preventing the blade from loosening or shifting during high-frequency impact shearing.

[0049] like Figures 6 to 8 As shown, the structure of the lower blade assembly 15 is similar to that of the upper blade assembly 14, also including a lower blade 151, a lower blade groove 152, a second connecting screw 153, a second limiting block 154, a second wedge-shaped washer 155, and a second hydraulic nut 156. The lower blade 151 has the same structure as the upper blade 141. Similarly, the lower blade 151 is equipped with a second limiting block 154 and a second wedge-shaped washer 155. The lower blade groove 152 is installed at the bottom of the gantry 1 for installing the lower blade 151, allowing the second limiting block 154 to be inserted and fixed. The second limiting block 154 is installed on the side of the lower blade 151 facing the lower blade groove 152, forming a precise fit with the lower blade groove 152 to ensure that the blade does not move laterally; the other side surface of the lower blade 151 is embedded with a second wedge-shaped washer 155, which acts as a clamping force when the screw is tightened. The second connecting screw 153 passes through the second wedge-shaped washer 155, the lower blade 151, the second limiting block 154, and the lower blade groove 152 in sequence, and passes through the connecting hole at the bottom of the gantry frame 1. The far end is locked to the structure of the gantry frame 1 by the second hydraulic nut 156.

[0050] In this embodiment, the output end of the shearing cylinder 13 is provided with a slot for accommodating and limiting the upper blade assembly 14. When the upper blade assembly 14 is installed at the output end of the shearing cylinder 13, the upper blade groove 142 is precisely embedded through the slot and forms a mechanical self-locking mechanism. This allows for initial positioning and stability before the first connecting bolt is fully tightened, preventing slippage or offset during installation. Simultaneously, the bottom of the gantry frame 1 is provided with a groove for receiving the lower blade assembly 15. The groove is a semi-closed structure with an upward opening, precisely matching the shape of the lower blade groove 152, for embedding and supporting the lower blade assembly 15. When the lower blade assembly 15 is placed in the groove, initial positioning is achieved before the second connecting screw 153 is tightened, preventing skewing or tilting during installation. The slot and groove, combined with the docking function of the tool changing device 2, provide a stable mechanical interface foundation, making the tool changing operation more automated, smooth, and reliable.

[0051] In this embodiment, a lateral compression cylinder 3 is provided on the other side of the gantry frame 1 opposite to the tool changing device 2, and a top compression cylinder 4 is also provided on the top of the gantry frame 1. Both can extend into the inner cavity of the gantry frame 1 and reciprocate along the direction perpendicular to the feed inlet 11 and along the height direction of the gantry frame 1, respectively, thus forming a pressing system. This enhances the stability and positioning reliability of the sheared metal material during the working process, improving the shearing quality and operational safety. Specifically, the output end of the lateral compression cylinder 3 can pass through the side wall of the gantry frame 1 and extend into the inner cavity of the gantry frame 1, reciprocating along the direction perpendicular to the feed inlet 11 during operation. The output end of the lateral compression cylinder 3 is connected to a pressing head. When the metal material enters and is positioned from the feed inlet 11, the lateral compression cylinder 3 is activated, pushing the pressing head against the side wall of the metal material to achieve lateral clamping or limiting of the metal material, preventing it from undergoing irregular movements such as lateral shifting or rotation due to inertia or vibration during the shearing process. The top compression cylinder 4 is located at the top of the gantry 1. The output end of the top compression cylinder 4 extends downward into the inner cavity of the gantry 1 and moves back and forth along the height direction of the gantry 1. The pressure head connected to the top compression cylinder 4 can apply a vertical clamping force from above to the metal material after it is fed into the shearing area, firmly pressing it onto the lower plane of the upper blade assembly 14, ensuring the shearing line is aligned, improving shearing accuracy, and avoiding adverse phenomena such as metal material jumping or rebounding.

[0052] In this embodiment, a length-fixing cylinder 51 and a length-fixing mechanism 52 driven by it are provided on one side of the discharge port 12 of the gantry frame 1. The length-fixing mechanism 52 can reciprocate along the feeding direction to position and limit the length of the metal material entering the shearing zone, thereby achieving precise length-fixed shearing. This not only improves the consistency and accuracy of the shearing dimensions, but also provides a reliable structural foundation for automated feeding and continuous shearing operations. Driven by the length-fixing cylinder 51, the length-fixing mechanism 52 can move forward to the shearing zone to limit the front end of the metal material, or it can retreat to an avoidance position to release the material, exhibiting good flexibility and control precision.

[0053] In this embodiment, a sloping chute box 111 is provided at the feed inlet 11, and wear-resistant liners are laid on the bottom and side walls of the sloping chute box 111 to guide, buffer, limit and protect the metal material, thereby further improving the working efficiency, stability and service life of the metal shearing machine in the feeding stage.

[0054] like Figure 9 As shown, in this embodiment, both the upper blade 141 and the lower blade 151 are four-bladed blades, and all four edges of each blade can be used as effective shearing edges. Compared with traditional single-bladed or double-bladed blades, the four-bladed blade structure significantly improves the usability and overall lifespan of the blade. The upper blade 141 and the lower blade 151 are regular rectangular bodies, thus possessing the same or similar shearing performance. When changing or flipping the blades, simply rotating or flipping the blade to the other side is sufficient to replace the new cutting edge, without needing to replace the entire blade, achieving the technical effects of quick blade replacement and low-cost maintenance.

[0055] like Figure 10 As shown, in this embodiment, the upper tool replacement cylinder 241 has a first hook 2411 at one end facing the upper tool assembly 14, and the upper tool assembly 14 has a first pin 147 at one end facing the upper tool replacement cylinder 241. Correspondingly, the lower tool replacement cylinder 242 has a second hook 2421 at one end facing the lower tool assembly 15, and the lower tool assembly 15 has a second pin 157 at one end facing the lower tool replacement cylinder 242. The first hook 2411 and the first pin 147, the second hook 2421 and the second pin 157 respectively form a pairing connection mechanism, realizing automatic tool engagement, disengagement and rapid tool replacement, greatly improving tool changing efficiency and safety.

[0056] In this embodiment, a discharge chute 121 is provided at the discharge port 12 of the gantry frame 1 to orderly discharge and collect the sheared metal material. The discharge chute 121 can be an inclined structure, located adjacent to the lower blade assembly 15, to receive metal blocks or profiles that fall instantaneously during the shearing process. Through the inclined guiding function of the discharge chute 121, the sheared metal material can automatically slide down to the collection area along the direction of gravity, avoiding material accumulation or blockage in the shearing area, and ensuring the continuity and efficiency of the shearing operation.

[0057] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
