Detailed Description

The embodiment of the application solves the technical problems that in the prior art, burrs exist in a notch, the notch is not thorough and the cutting efficiency is low when a disc cutter is used for cutting by providing the honeycomb core plate cutting device.

The technical scheme in the embodiment of the application aims to solve the technical problems, and the overall thought is as follows:

the honeycomb core plate cutting device comprises a rotary driving unit and a polygonal cutter body, wherein the polygonal cutter body can rotate under the driving of the rotary driving unit to cut the plane contour.

Therefore, when the cutter body advances along the set track on the frame, the cutter body can cut for several times from the front end of the cutter body to the rear end of the cutter body at a certain position on the honeycomb core board, which is separated from the position, so that the incision is very regular, no burrs exist, the incision is very thorough, no adhesion phenomenon exists, and meanwhile, the advancing speed of the cutter body can be accelerated, and the cutting efficiency is improved. In contrast, conventional disc cutters do not themselves rotate when cutting, and other locations, except for the outermost locations, do not create an effective cutting force on the honeycomb core.

On the other hand, the outer contour of the cutter body is designed into a polygonal structure, when the cutter body advances along a set track on the frame, only the cutter point part on the polygonal outer contour is contacted with the bottom of the honeycomb core plate, and the straight line contour between adjacent cutter points of the polygon is not contacted with the bottom of the honeycomb core plate, so that intermittent contact with the bottom of the honeycomb core plate is realized, and the honeycomb core plate is not driven to move forwards along with the cutter point part. Meanwhile, the cutting blind area can be eliminated by reasonably adjusting the diameter, the speed and the cutting depth of the cutter body, and the effective cutting is realized. In comparison, when the traditional disc cutter is used for cutting, the circular outer contour of the bottom of the disc cutter is always contacted with the honeycomb core plate, so that larger forward force can be generated to drive the honeycomb core plate to shift forward, and deformation is generated.

In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

Example 1

Fig. 2 is a schematic overall structure of an exemplary honeycomb core cutting device according to the present embodiment, where the honeycomb core cutting device includes a cutting power module 32 and a polygonal cutter 40, and the polygonal cutter 40 can rotate under the driving of the cutting power module 32 to cut a plane contour.

Specifically, as shown in fig. 4, the polygonal cutter 40 includes a polygonal cutter body 41, a shaft hole 43 is provided in the center of the polygonal cutter body 41, cutting blades 42 having a multi-stage straight line profile are formed along the outer edge of the polygonal cutter body 41, and a cutting tip 44 is formed between adjacent cutting blades 42.

The tail end of the mounting shaft 33 of the cutting power module 32 is provided with a concave groove body, a power rotating shaft 38 is arranged in the groove body, and a polygonal cutter 40 is fixedly mounted on the power rotating shaft 38 through a shaft hole 43. In operation, the cutting power module 32 drives the power shaft 38 to rotate, thereby driving the polygon cutter 40 mounted on the power shaft 38 to rotate.

Specifically, the cutting power module 32 is provided with a rotating shaft driving part, and the rotating shaft driving part is in transmission connection with the power rotating shaft 38, so that the polygonal cutter 40 rotates, and the honeycomb core plate 6 is cut by rotating a cutting blade 42 at the outer edge of the polygonal cutter body 41.

The cutting power module 32 is provided with a mounting shaft driving part, and the mounting shaft driving part is connected with the mounting shaft to drive the mounting shaft to rotate, so as to adjust the cutting direction of the polygonal cutter 40 and realize direction adjustment in a controllable angle.

The above constitutes a multi-axis control system, so that the polygonal cutter 40 can be controlled to cut the plane profile.

In an alternative embodiment, the spindle drive and the mounting spindle drive of the cutting power module 32 are drive motors.

Further, a part (upper part in fig. 2) of the polygonal cutter body 41 of the polygonal cutter 40 is located in the groove at the end of the mounting shaft 33 of the cutting power module 32, and the other part (lower part in fig. 2) is exposed to the outside of the groove. Wherein the height of the part of the polygonal cutter body 41 exposed outside the groove body is not less than the thickness of the honeycomb core plate 6.

In a preferred embodiment, the polygonal cutter body 41 is a regular polygonal cutter body, such as a regular octagonal cutter body.

As shown in fig. 2, in some embodiments, a pressing component for pressing the honeycomb core plate 6 is disposed on the mounting shaft 33 of the cutting power module 32, so as to perform a certain positioning function on the honeycomb core plate 6 during cutting, and make the honeycomb core plates at two ends of the cutter body flat during cutting by the polygonal cutter 40, so that the cuts are tidy.

Specifically, the pressing assembly includes:

an elastic member 34 sleeved on the output shaft 33, and one end (upper end in fig. 2) of the elastic member 34 is connected with the output shaft 33; and

And a pressure plate 35 connected to the other end (lower end in fig. 2) of the elastic member 34.

The platen 35 is configured with an abutment surface 36 for abutting against the honeycomb core plate 6 at one end (lower end in fig. 2) near the polygonal cutter 40. The abutting surface 36 is provided with a cutter groove for the polygonal cutter body 41 to pass through. The abutting surface 36 is curved upward along both ends of the traveling direction of the polygonal blade body 41 to form a transitional circular arc shape. The arrangement of the transitional arc abutting surface 36 can lead the honeycomb core plate 6 to enter the abutting surface 36 more easily, and reduce the anti-astringency feeling of the honeycomb core plate 6 pressed in the proceeding process.

In the above embodiment, the elastic member 34 may be a spring, the elastic potential energy of the elastic member 34 is not easy to be too large or too small, the honeycomb core plate 6 is deformed due to the too large elastic potential energy, the honeycomb core plate 6 is not pressed due to the too small elastic potential energy, and the state that the pressure plate 35 just presses the honeycomb core plate 6 can be kept by selecting the elastic potential energy of the elastic member 34.

In other embodiments, as shown in fig. 3, the pressing assembly may also have the following structure: the pressing assembly includes two pressing rollers 37, and the two pressing rollers 37 are disposed at the front and rear sides of the polygonal cutter body 41, respectively.

Specifically, in use, the cutting power module 32 is mounted on the bracket 31, the pressing rollers 37 are also mounted on the bracket 31, and each pressing roller 37 is respectively connected with the bracket 31 through an elastic member, so that the pressing rollers 37 can elastically press against the honeycomb core plate 6.

In other embodiments, the platen 35 and the press roller 37 are present simultaneously to provide a more stable pressing action against the honeycomb core plate 6.

When the honeycomb core plate cutting device provided in this embodiment is used, the cutting power module 32 is mounted on the bracket 31 and can advance along the set track, and when the polygonal cutter body 41 is driven to advance along the set track, the cutting power module can cut different parts of the rotating polygonal cutter body 41 for several times in a period from the time that the front end of the polygonal cutter body 41 is in first contact with a certain position on the honeycomb core plate to the time that the rear end of the polygonal cutter body 41 is away from the position, so that the cutting is very regular, no burrs exist, the cutting is very thorough, no adhesion phenomenon exists, and meanwhile, the advancing speed of the polygonal cutter body 41 can be accelerated, and the cutting efficiency is improved.

On the other hand, the outer contour of the polygonal cutter body 41 is designed into a polygonal structure, when the polygonal cutter body 41 advances along a set track on the frame, only the cutter point 44 on the polygonal outer contour contacts the bottom of the honeycomb core plate, and the straight line contour between the adjacent cutter points of the polygon does not contact the bottom of the honeycomb core plate, so that intermittent contact with the bottom of the honeycomb core plate is realized, and the honeycomb core plate is not driven to move forward along with the intermittent contact. Meanwhile, since the polygonal cutter body 41 rotates, the same part of the bottom of the honeycomb core plate can be passed by a plurality of cutter points on the polygonal outer contour for a plurality of times, so that powerful cutting is generated, and a cutting blind area can not exist.

As shown in fig. 5, when the polygonal cutter body 41 makes a high-speed cut, the cutter tip 44 passes through the origin (corresponding to an n-sided cutter) n times per rotation, and the area enclosed by the curve formed by the two adjacent cutter tips 44 passing through the lowest point in turn and the horizontal line passing through the lowest point is very close to zero. The setting can greatly reduce the adhesion effect of the honeycomb core plate 6 after the cutter cuts, and avoid the continuous cutting problem of the honeycomb core plate 6.

The cutting tool is a regular octagonal tool with a diagonal dimension of 36mm, a cutting speed of 48m/min and a tool rotating speed of 12000rpm, and a closed contour area defined by a curve formed by two adjacent tool tips 44 passing through the lowest point and a horizontal line passing through the lowest point is 0.0003mm ² The maximum dimension of the profile in the vertical direction is less than 2 μm, and the cutting blind area can be eliminated by slightly adjusting the depth of the cutter to be a little deeper (more than 2 μm), so that the honeycomb core plate 6 is not cut continuously.

Example two

Honeycomb core panels are often easily deformed. For example, the aluminum honeycomb core plate used for the aluminum honeycomb composite plate for the suspended ceiling is generally smaller than 0.1mm in thickness of aluminum foil, and is generally larger than 3mm in hexagonal side length, and the density of the stretched aluminum honeycomb core plate is generally 25kg/m ³ ～100kg/m ³ In between, the shape stability is extremely poor.

When the traditional disc cutter is used for cutting, the cutting force of the blade always drives the honeycomb core to move forwards, and deformation is generated. The method is to press the honeycomb core plate by adopting an upper plate and a lower plate to realize basic positioning and clamping and prevent deformation of the honeycomb core plate. However, the pressing force is difficult to control. The pressing force is too small, the honeycomb core plate is easy to be forced to deform due to the fact that the honeycomb core plate is biased by a belt under the action of the cutting force when being cut, the cutting of a preset contour cannot be realized, and burrs are formed on the cutting edge; the pressing force is too large, so that the aluminum foil is easy to deform, the honeycomb core is collapsed, the quality of a finished product is influenced, the cutting effect is poor, and the cutting efficiency is low. Meanwhile, a special pressing plate is manufactured according to different cutting contour requirements, so that the cost is high and the universality is weak.

According to the embodiment, on the basis of the honeycomb core plate cutting device, the honeycomb core plate cutting system is designed, the honeycomb core plate is positioned based on the pressing component of the cutting device, the traditional positioning structure that the honeycomb core plate is pressed by the upper plate and the lower plate is omitted, and therefore finished product defects caused by deformation or collapse of the honeycomb core plate due to the influence of pressing force are avoided, and the cutting effect is effectively guaranteed.

In addition, the design movable support is provided with the cutting tool, so that the flexibility of the cutting tool in cutting the honeycomb core plate is improved, and the cutting effect of different contours can be realized.

Further, through setting up damping cushion or negative pressure transmission band that frictional force is big, fix a position the honeycomb core, further improved the cutting effect.

As shown in fig. 6 to 8, the present embodiment provides a honeycomb core cutting system including:

a honeycomb core board supporting platform 5 for supporting a honeycomb core board 6 to be cut;

Further, a moving bracket 31 spans the honeycomb core supporting platform 5 and can be driven by a bracket driving device to reciprocate along the length direction (Y direction in fig. 8) of the honeycomb core supporting platform 5.

The movable support 31 is provided with a guide rail and a cutter driving device, the cutting power module 32 of the cutting device is arranged on the guide rail on the movable support 31 and is connected with the cutter driving device, and the cutting power module 32 can slide along the guide rail in the width direction (X direction in fig. 8) of the honeycomb core plate bearing platform 5 under the driving of the cutter driving device.

The mounting shaft of the cutting power module 32 can be rotated in a direction perpendicular to the honeycomb core support platform 5 (Z direction in fig. 6) to adjust the cutting direction of the polygonal cutter 40.

When in use, under the action of the pressing component of the cutting device, the honeycomb core plate is positioned on the honeycomb core plate supporting platform 5, and no displacement is generated.

In an alternative embodiment, the honeycomb core supporting platform 5 is provided with a damping cushion layer 51, and the honeycomb core 6 is disposed on the damping cushion layer 51, so as to further prevent the honeycomb core 6 from being displaced during the cutting process. Illustratively, the damping blanket 51 may be a felt.

In another optional embodiment, the honeycomb core supporting platform 5 is provided with a hollowed supporting surface, a negative pressure generating mechanism is arranged below the hollowed supporting surface, the honeycomb core 6 is arranged on the hollowed supporting surface, a film is arranged on the upper surface of the honeycomb core 6, and in operation, the negative pressure generating mechanism generates negative pressure to generate adsorption action on the film, so that the honeycomb core between the film and the hollowed supporting surface is adsorbed and tightly attached to the hollowed supporting surface, and the honeycomb core 6 can be further prevented from shifting in the cutting process.

In another alternative embodiment, as shown in fig. 7, the honeycomb core supporting platform 5 is provided with a hollowed supporting surface, a negative pressure generating mechanism is arranged below the hollowed supporting surface, a movable conveying belt 21 is wrapped on the hollowed supporting surface, and the honeycomb core 6 is placed on the conveying belt 21.

When cutting, the negative pressure generating device is started to generate negative pressure adsorption, the honeycomb core plate 6 is flatly attached to the conveying belt 21, and the conveying belt 21 does not move at this time and is used as a damping cushion layer. When not cutting, the negative pressure generating means is stopped, the negative pressure suction is released, and the conveyor belt 21 is movable to convey the honeycomb core plate 6.

In some embodiments, the honeycomb core board supporting platform 5 is divided into a plurality of independent cavities, a control valve is arranged between the negative pressure generating device and each cavity, and the cavities are connected with the negative pressure generating device in an on-off mode through the control valve. Here, the negative pressure generating device can adopt the existing mature negative pressure generator, the negative pressure connecting port of the negative pressure generator is connected with the plurality of cavities in parallel through the switching pipeline, the on-off state is controlled between each cavity and the pipeline of the negative pressure generator through a control valve, and the negative pressure adsorption effect of different area areas on the honeycomb core board supporting platform 5 is realized by controlling the on-off of different control valves. When the negative pressure generator is started, negative pressure can be generated in the needed subarea cavity, and at the moment, if a cover exists on the upper surface of the corresponding subarea, the cover can be adsorbed on the upper surface of the platform.

Here, in order to further facilitate the control of different cavities, the PLC circuit board may be used to program and control the negative pressure adsorption area of the negative pressure generator, and illustratively, the hollow support surfaces corresponding to the cavities on the honeycomb core board support platform 5 are divided into different areas, each area has a cavity or a plurality of cavities, and all control valves in the area are controlled to be opened by external instructions, so that the cavities are communicated with the negative pressure generator to form the adsorption state of the area.

In some embodiments, the conveyor belt 21 is made of a breathable material, and a conveying roller set is disposed on the honeycomb core supporting platform 5, and the conveyor belt 21 is driven by the conveying roller set to move relative to the honeycomb core supporting platform 5.

In order to further enhance the conveying effect of the conveying belt 21, a driving roller 22, a driven roller 23 and a tensioning roller 24 can be arranged on the honeycomb core plate supporting platform 5 to form a conveying roller set, and the conveying belt 21 is coated on the conveying roller set to form the conveying effect. The thickness of the conveying belt 21 is required to be uniform, so that the function of the negative pressure adsorption platform is not affected when the conveying belt is cut, and the conveying belt has certain air permeability; the conveyor belt 21 requires a certain roughness and flexibility in order to allow the honeycomb core to be processed without easy movement thereon. The material of the conveyor belt 21 should therefore follow the following principle: the surface friction coefficient of the conveyor belt 21 needs to be large enough, and the honeycomb core is not easy to generate relative displacement when being placed on the conveyor belt 21, so that the honeycomb core plate 6 is not easy to deform when being cut. The conveyor belt 21 may be made of a felt material having a certain air permeability, for example.
