Description

Technical Field

[0001] This application belongs to the field of cutting machines, and in particular relates to a high-efficiency double-head cutting machine. Background Technology

[0002] Dual-head panel saws, as an efficiency optimization solution for CNC machining equipment, rely on the core technology of collaborative operation between two independent heads to improve processing efficiency. The dual-head design allows the equipment to simultaneously execute the same or related processes, making it particularly suitable for the synchronous processing of symmetrical slots and irregular contours on both sides of wood panels, theoretically achieving twice the processing efficiency of a single-head machine. However, existing technologies have significant limitations: both heads share a single tool magazine, which needs to be physically divided according to the number of heads. For example, a 12-tool magazine needs to be configured with 6 pairs of identical tools to ensure synchronous tool changes between the two heads. While this design simplifies the tool-changing logic, it is constrained by the physical space of the equipment and the capacity of the tool magazine, resulting in a significant reduction in the types of tools that can be stored. When machining tasks involve multiple tool combinations, frequent tool magazine changes or adjustments to tool configurations are necessary, severely reducing the equipment's flexibility and processing range, making it difficult to meet the diverse processing needs of complex workpieces. Therefore, existing technologies require further improvement and enhancement. Utility Model Content

[0003] This invention provides a high-efficiency dual-head cutting machine that solves the problem of increasing the tool magazine configuration while maintaining the synergistic advantages of dual heads, in order to meet the diverse processing needs of complex workpieces.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A high-efficiency double-head cutting machine includes a bed and a gantry beam spanning above the bed. A double-head assembly with independent processing capabilities and capable of synchronous or asynchronous processing of sheet metal is located on the gantry beam. A tool magazine assembly is located on the lower side of the gantry beam. The tool magazine assembly includes a support plate, a slide rail slider mechanism, and a drive mechanism. The support plate is connected to the gantry beam through the slide rail slider mechanism. The front end of the support plate has a main tool magazine area, the two sides of the support plate have side tool magazine areas, and the upper end of the support plate has a spare tool magazine area. The drive mechanism drives the support plate to move along the length of the bed, so that each tool magazine area can be aligned with the spindle for tool changing operations to meet diverse processing needs.

[0006] The aforementioned structure, a dual-head cutting machine, features a three-tiered tool magazine architecture: a main tool magazine area (front end), side tool magazine areas (both sides), and a spare tool magazine area (top end), forming a three-dimensional storage system. This increases tool positions by more than 50% compared to traditional solutions. The side tool magazine areas can be independently configured with tool combinations to support asymmetrical machining needs. The spare tool magazine area, as an extension area, further increases the variety of tools available, adapting to more complex machining processes and tool changing requirements. Vertical space utilization is improved, providing a larger tool capacity within the same footprint. The movable tool magazine components allow for more flexible tool configurations, reducing tool change time and improving machining efficiency. Furthermore, the multiple tool magazine areas increase tool diversity, meeting the machining needs of complex workpieces.

[0007] In a preferred implementation, the main tool magazine area, the side tool magazine area, and the spare tool magazine area all include a travel plate, and the travel plate is equipped with evenly spaced tool holders.

[0008] In the preferred implementation, the length of the main tool magazine travel plate matches the width of the machine bed machining table, and the tool elements on the tool holder are distributed in a mirror-symmetrical manner to both sides with the center line of the magazine as the reference.

[0009] In a preferred implementation, the travel plate of the side tool magazine area and the travel plate of the main tool magazine area are at the same height, and the distance between the tool holder of the side tool magazine area and the travel plate of the main tool magazine area is greater than or equal to the spindle diameter.

[0010] In the preferred implementation, the length of the spare tool magazine area travel plate is adapted to the length of the support plate, and two brackets perpendicular to the support plate are connected to the bottom of the spare tool magazine area travel plate. The brackets and the support plate are detachably connected.

[0011] In the preferred implementation, the support plate is provided with two slide rails, and the bottom of the bracket is provided with a slide groove, which is connected to the slide rail.

[0012] In the preferred implementation, the distance between the upper end of the support plate and the bottom end of the gantry beam is greater than the height of the tool in the spare tool magazine area.

[0013] In the preferred implementation, along the moving direction of the support plate, the spare tool magazine area is located between the main tool magazine area and the side tool magazine area.

[0014] In a preferred embodiment, the drive mechanism includes a drive cylinder, the support plate is provided with a fixing part, the piston rod of the drive cylinder is connected to the fixing part, and the cylinder body of the drive cylinder is connected to the lower side of the gantry beam.

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit and scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0022] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In this utility model, unless otherwise expressly specified and limited, the first feature being "upper" or "lower" than the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two main bodies at the connection point are not connected by an intermediate structure, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] In this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0025] The present invention will now be described with reference to the accompanying drawings.

[0026] The specific solution adopted is as follows:

[0027] like Figure 1-3 As shown, this utility model provides a high-efficiency double-head cutting machine, including a bed and a gantry beam 1 spanning above the bed. A double-head assembly 2 with independent processing capabilities and capable of processing sheet metal synchronously or asynchronously is located on the gantry beam 1. A tool magazine assembly is located on the lower side of the gantry beam 1. The tool magazine assembly includes a support plate 3, a slide rail slider mechanism 31, and a drive mechanism 32. The support plate 3 is connected to the gantry beam 1 through the slide rail slider mechanism 31. The front end of the support plate 3 is provided with a main tool magazine area 33, the two sides of the support plate 3 are provided with side tool magazine areas 34, and the upper end of the support plate 3 is provided with a spare tool magazine area 35. The drive mechanism 32 drives the support plate 3 to move along the length of the bed, so that each tool magazine area can be aligned with the spindle 20 for tool changing operations to meet diverse processing needs.

[0028] The aforementioned structure, a dual-head cutting machine, features a three-tiered tool magazine architecture. The main tool magazine area 33 (front end), side tool magazine areas 34 (both sides), and a spare tool magazine area 35 (upper end) form a three-dimensional storage system, increasing tool positions by more than 50% compared to traditional solutions. The side tool magazine areas 34 can be independently configured with tool combinations, breaking the "paired configuration" limitation and supporting asymmetric machining needs. The spare tool magazine area 35 serves as an expansion interface, further increasing the variety of tools available in the magazine and adapting to more complex machining processes. Vertical space utilization is improved, providing a larger tool capacity within the same floor area. The movable tool magazine components allow for more flexible tool configurations, reducing tool change time and improving machining efficiency. Furthermore, the multiple tool magazine areas increase tool diversity, meeting the machining needs of complex workpieces.

[0029] See Figure 2 and Figure 3 The main tool magazine area 33, the side tool magazine area 34, and the spare tool magazine area 35 all include a travel plate 302, with evenly spaced tool holders 303 on the travel plate 302. The length of the travel plate 302 in the main tool magazine area 33 matches the width of the machining table on the bed, and the tool elements on the tool holders 303 are distributed symmetrically to both sides of the magazine centerline. The travel plate 302 of the side tool magazine area 34 is at the same height as the travel plate 302 of the main tool magazine area 33, and the distance between the tool holders 303 of the side tool magazine area 34 and the travel plate 302 of the main tool magazine area 33 is greater than or equal to the diameter of the spindle 20.

[0030] The mirror-symmetric layout of the main tool magazine area 33 makes tool changing more efficient for the dual-head machine, as both heads can simultaneously align with their respective tools, reducing waiting time. The side tool magazine area 34 and the travel plate 302 of the main tool magazine area 33 are at the same height. The drive mechanism 32 only needs to push the support plate 3 forward to bring the side tool magazine to the tool changing position. The distance between the tool holder 303 of the side tool magazine area and the travel plate 302 of the main tool magazine area 33 is greater than or equal to the diameter of the spindle 20. During tool changing, the tool holder is lowered first, and then the spindle 20 distance is advanced to disengage the tool from the tool holder. This avoids interference during tool changing and improves the safety of the equipment.

[0031] In a preferred embodiment of this application, the length of the travel plate 302 of the spare tool magazine area is adapted to the length of the support plate 3, and the bottom of the travel plate 302 of the spare tool magazine area is connected to two brackets 304 perpendicular to the support plate 3, and the brackets 304 are detachably connected to the support plate 3.

[0032] The length of the travel plate 302 in the spare tool magazine area 35 is adapted to the length of the support plate 3, ensuring that the spare tool magazine area 35 can make full use of the space of the support plate 3 and increase the tool storage capacity. The bracket 304 is detachably connected to the support plate 3, making the installation and removal of the spare tool magazine area 35 more flexible and convenient for maintenance and upgrades. The spare tool magazine area 35 is higher than the main tool magazine area 33 and the side tool magazine area 34, utilizing the upper space for tool placement, further increasing the tool storage capacity, while avoiding interference with the main tool magazine area 33 and the side tool magazine area 34.

[0033] See Figure 3 The support plate 3 is equipped with two slide rails 300, and the bottom of the bracket 304 is provided with a slide groove. The slide groove and the slide rails 300 are connected to each other, allowing the bracket 304 to slide linearly on the support plate 3, which is convenient for adjustment and positioning. Fixing holes can be provided on the side of the slide groove, and bolts can be passed through the fixing holes. The bolts are rotated to hold the slide rails 300 in place. When disassembly is required, simply rotate the bolts in the opposite direction.

[0034] Furthermore, the distance between the upper end of the support plate 3 and the bottom end of the gantry beam 1 is greater than the height of the tools in the spare tool magazine area 35. This ensures that the tools in the spare tool magazine area 35 will not collide with the gantry beam 1 during movement, thus ensuring the safety of the tools in the spare tool magazine area 35 during movement. Along the moving direction of the support plate 3, the spare tool magazine area 35 is located between the main tool magazine area 33 and the side tool magazine area 34. The linear drive mode allows the tools in the spare tool magazine area 35 to quickly reach the tool changing position, shortening the tool changing time.

[0035] In a preferred embodiment of this application, the drive mechanism 32 includes a drive cylinder, the support plate 3 is provided with a fixing part 301, the piston rod of the drive cylinder is connected to the fixing part 301, and the cylinder body of the drive cylinder is connected to the lower side of the gantry beam 1.

[0036] See Figure 2 and Figure 3 A connecting plate is installed on the lower side of the gantry beam 1, and a sliding block is installed on the connecting plate. The slide rail 300 on the support plate 3 is connected to the sliding block. The drive cylinder provides power, and the extension and retraction of the piston rod pushes the support plate 3 to move on the slide rail 300. The cooperation between the slide rail 300 and the sliding block ensures the straightness and stability of the support plate 3 during the movement. By controlling the stroke of the drive cylinder, the support plate 3 is precisely moved to the tool changing position, that is, directly below the spindle 20.

[0037] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0038] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
