Description

A shoe mold machine tool Technical Field

[0001] The present invention relates to the technical field of machine tools, in particular to a shoe mold machine tool. Background Art

[0002] CNC machine tool is the abbreviation of digitally controlled machine tool. It is an automated machine tool equipped with a program control system. It can automatically process parts according to the shape and size required by the drawing.

[0003] Existing sole molds are made by carving them out using five-axis machine tools. However, traditional machine tools usually have their protective shells and components such as electrical boxes and pneumatic boxes that are separately and independently set. The separate electrical boxes and pneumatic boxes will cause the machine tool to be bloated and have a high floor space occupancy rate. In addition, the wires and pipes connecting the electrical box, pneumatic box and the internal components of the machine tool protective shell will be directly exposed to the outside world, making the machine tool difficult to assemble and easily causing the exposed wires and pipes to be knocked by the outside world, causing the machine tool to malfunction and become unable to operate, affecting the stability of the machine tool.

[0004] Furthermore, to facilitate operations such as machine tool maintenance, workpiece loading, and tool replacement, the machine tool protective housing must have corresponding open spaces to facilitate operations such as machine tool maintenance, workpiece loading, and tool replacement by processing personnel. To ensure the processing safety of CNC machine tools, existing machine tool protective housings generally have protective doors that can be opened and closed at positions corresponding to the open spaces. However, frequent opening and closing of the protective doors can cause waste chips generated and splashed during workpiece processing inside the machine tool to fall into the protective door tracks. The waste chips that fall and accumulate in the protective door tracks can affect the smoothness of the protective door opening and closing, and in severe cases, the protective door can become stuck and cannot be opened and closed normally.

[0005] At the same time, the workbench inside the traditional machine tool is large and has a high center of gravity, which is not conducive to the miniaturized internal layout of the five-axis machining center for sole molds.

[0042] The beneficial effects of the present invention are:

[0043] 1. In the shoe mold machine tool of the present invention, the electrical box assembly and the pneumatic box assembly are built into the machine tool protective shell, eliminating the need for additional external electrical box assembly and pneumatic box assembly. This makes the machine tool highly integrated and more compact, effectively reducing the size of the machine tool and reducing the floor space occupied by the machine tool. The electrical box assembly and the pneumatic box assembly are arranged on the same side of the protective shell, which can improve the efficiency of laying out lines and pipes during the production and assembly of the machine tool structure, and facilitate the subsequent maintenance of the machine tool, avoiding external collisions that may cause damage to the lines and pipes and affect the use of the machine tool. At the same time, the door rail assembly makes it easy for staff to inspect the internal structure of the machine tool through the operation port, and the lifting door assembly facilitates the automatic loading and unloading equipment at the rear end of the machine tool to automatically load and unload materials, avoiding the inconvenience of maintenance operations and loading and unloading operations at the same window.

[0044] 2. In the door rail assembly of the shoe mold machine tool of the present invention, the soft rubber scraper arranged at the bottom of the first protective door avoids direct contact between the bottom of the first protective door and the guide groove through the interference fit between the edge and the two side walls of the guide groove. The elasticity of the soft rubber scraper effectively filters and absorbs the vibration transmitted from the protective shell, thereby preventing the first protective door from vibrating in the guide groove and generating abnormal noise. When opening and closing the first protective door, the soft rubber scraper can also scrape away waste chips and cutting fluid that fall into the guide groove, keeping the guide groove clean and avoiding waste chips from being blocked between the guide groove and the first protective door.

[0045] 3. In the workbench of the shoe mold machine tool of the present invention, the first guide slopes are arranged opposite to each other on both sides of the second water guide groove, so that the waste chips generated by the processing on the workbench can easily fall into the second water guide groove and be discharged to the outside of the workbench body along the second water guide groove, thereby preventing the waste chips accumulated on the workbench body from affecting the processing of the machine tool. The first support bridge and the second support bridge are respectively arranged above the second water guide groove through the first guide slopes of the connecting beam, thereby effectively reducing the height of the workbench and realizing miniaturization of the workbench.

[0046] 4. The method of the present invention solves the problem of inconsistent machining knife marks caused by inconsistent machining speeds of various parts of a shoe mold workpiece, thereby achieving better machining effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] 1, 2 and 7, in some embodiments, a shoe mold machine tool according to the present invention includes: a protective shell 4000 provided on a machine tool bed 1000, the front and rear ends of the protective shell 4000 are respectively provided with an operating port 4100 and a material taking port 4200; a door rail assembly 5000, the door rail assembly 5000 is provided on the front end of the protective shell 4000 and is used to open and close the operating port 4100; a lifting door assembly 6000, the lifting door assembly 6000 is provided on the rear end of the protective shell 4000 and is used to open and close the material taking port 4200; an electrical box assembly 7000 and a pneumatic box assembly 8000, both of which are provided on the protective shell 4000. On the same side of the protective shell 4000, the workbench is set on the bed 1000 through the first translation slide mechanism 1100, and the workbench is driven by the first translation slide mechanism 1100 to translate within the protective shell 4000 and move between the operating port 4100 and the material removal port 4200; the spindle assembly 3000, the spindle assembly 3000 is set on the bed 1000 within the protective shell 4000 through the gantry 1300, and the spindle assembly 3000 is located above the workbench; and the tool magazine assembly 9000, the tool magazine assembly 9000 is set on the bed 1000 within the protective shell 4000, and the tool magazine assembly 9000 is used to store tools and switch tools on the spindle assembly 3000.

[0065] The electrical box assembly 7000 and pneumatic box assembly 8000, built into the machine tool protective shell 4000, eliminate the need for separate external electrical box assemblies 7000 and 8000, making the machine tool highly integrated and more compact, effectively reducing its size and floor space. The electrical box assembly 7000 and pneumatic box assembly 8000 are located on the same side of the protective shell 4000, improving the efficiency of wiring and piping during machine tool structure production and assembly, and facilitating subsequent maintenance by preventing damage to wiring and piping due to external collisions that could affect the machine's operation. Furthermore, the door rail assembly 5000 allows workers to inspect the machine's internal structure through the operating port 4100, and the lift door assembly 6000 facilitates automated loading and unloading of materials by automatic loading and unloading equipment at the rear end of the machine tool, avoiding the inconvenience of having maintenance and loading and unloading operations performed at the same window.

[0066] 1 and 7 , in some embodiments of the present invention, since in daily operation of a machine tool, the frequency with which the operator controls the operation of the machine tool by operating the electrical box assembly 7000 is higher than the frequency with which the operator operates the pneumatic box assembly 8000, a conventional machine tool generally sets the pneumatic box assembly 8000 in the rear end of one side of the protective shell 4000, and the pneumatic box assembly 8000 is operated through one side of the protective shell 4000. A pneumatic box door is provided at the position corresponding to the pneumatic box assembly 8000 at the rear end of one side of the protective shell 4000, and the operator can debug and repair the pneumatic box assembly 8000 by opening the pneumatic box door; the electrical box assembly 7000 is set at the front end of the pneumatic box assembly 8000 in the protective shell 4000, and the electrical box assembly 7000 is operated through the front end of the protective shell 4000. Specifically, a control panel is provided at one side of the operating port 4100 at the front end of the protective shell 4000, and the electrical box assembly 7000 is operated through the control panel.

[0067] 1 , 7 and 9 , in some embodiments of the present invention, the gantry 1300 includes two columns 1310 connected to the bed 1000 and a beam 1320 connected to the two columns 1310; the bottom of the rear end of the beam 1320 is also provided with an avoidance gap 1322 (see FIG7 ) at the position corresponding to the material removal port 4200. The avoidance gap 1322 at the rear end of the beam 1320 of the gantry 1300 avoids interfering with the loading and unloading actions of external automated loading and unloading equipment while ensuring the rigidity of the gantry 1300, making it easier for external automated loading and unloading equipment to efficiently take and unload materials, thereby improving the production efficiency of the machine tool. The concave design of the avoidance gap 1322 can make the size of the machine tool protective shell 4000 more compact.

[0068] In addition, referring to Figures 7 and 9, the front end of the beam 1320 is connected to a longitudinal lifting mechanism through a second translation slide rail mechanism 1321, and the front end of the longitudinal lifting mechanism is connected to the spindle assembly 3000. The spindle assembly 3000 is arranged above the workbench, and the automatic loading and unloading device extending from the material taking port 4200 removes the processed workpiece from the workbench or places the workpiece to be processed on the workbench. On the other side of the workbench away from the electrical box assembly 7000, a tool magazine assembly 9000 for storing tools and replacing tools clamped on the spindle assembly 3000 is also provided in the protective shell 4000. The tool magazine assembly 9000 replaces the tool clamped on the spindle assembly 3000 when the spindle assembly 3000 needs to replace the tool.

[0069] 1, 2, 3 and 6, in some embodiments of the present invention, the door rail assembly 5000 includes: a first translation guide rail 5600 at least partially disposed on the protective shell 4000 at the top of the operating port 4100, a second translation guide rail 5700 at least partially disposed on the protective shell 4000 at the bottom of the operating port 4100, at least a portion of the second translation guide rail 5700 is located at the bottom of the operating port 4100, and a guide groove 5710 is provided on the second translation guide rail 5700; The first protective door 5100 on the protective shell 4000 can cover the operating port 4100 when the first protective door 5100 is closed. The top of the first protective door 5100 is provided with a first pulley 5200 that rolls and cooperates with the first translation guide rail 5600. The bottom of the first protective door 5100 is set in the guide groove 5710. The bottom of the first protective door 5100 is provided with a second pulley 5300 that rolls and cooperates with the second translation guide rail 5700. The first translation guide rail 5600 disperses the first protective door 5100 from the second translation guide rail. The load of the guide rail 5700 is increased, and the cooperation of the first pulley 5200 and the second pulley 5300 improves the smoothness of opening and closing of the first protective door 5100 on the protective shell 4000, making it smoother for the staff to open and close the first protective door 5100 and reducing labor intensity; the soft rubber scraper 5400 provided at the bottom of the first protective door 5100, at least part of the edge of the soft rubber scraper 5400 is interference fit with the two side walls of the guide groove 5710, and the interference fit between the edge of the soft rubber scraper 5400 and the two side walls of the guide groove 5710 is realized. In cooperation, the soft rubber scraper 5400 can effectively filter and absorb the vibration transmitted from the protective shell 4000 through its elasticity, thereby reducing the vibration of the first protective door 5100 and the abnormal noise caused by the vibration. When opening and closing the first protective door 5100, the soft rubber scraper 5400 can also scrape the waste chips and cutting fluid that fall into the guide groove 5710 away from the guide groove 5710, thereby playing a scraping role, effectively keeping the guide groove 5710 clean, and preventing waste chips from being blocked between the guide groove 5710 and the first protective door 5100 and the second pulley 5300.

[0070] 3 and 4, the number of soft rubber scrapers 5400 is at least two, and the two adjacent soft rubber scrapers 5400 are respectively arranged on the left and right sides of the second pulley 5300, and the soft rubber scraper 5400 is spaced apart from the second pulley 5300. Furthermore, the two adjacent soft rubber scrapers 5400 are symmetrically arranged on the left and right sides of the second pulley 5300. Specifically, the soft rubber scraper 5400 is vertically arranged, and the front and rear sides of the soft rubber scraper 5400 are respectively in contact with the two side walls of the guide groove 5710. The soft rubber scraper 5400 is perpendicular to the extension direction of the second translation guide rail 5700, so that the scraping angles of the soft rubber scraper 5400 and the two side walls of the guide groove 5710 are the same, ensuring consistent scraping effect on both sides of the guide groove 5710. The contact area between the soft rubber scraper 5400, which is perpendicular to the extension direction of the guide groove 5710, and the side walls of the guide groove 5710 is larger, which can offset the gap between the second roller 5300 and the side walls of the guide groove 5710, effectively reducing the vibration and abnormal noise caused by the machine tool protective housing 4000. Furthermore, the bottom edge of the soft rubber scraper 5400 abuts the bottom wall of the guide groove 5710, which can improve the scraping effect.

[0071] In some embodiments of the present invention, the bottom of the first pulley 5200 rolls against the top of the first translation guide rail 5600, and the second pulley 5300 rolls against the sidewalls of the guide groove 5710. Specifically, even after being scraped by the soft rubber scraper 5400, a small amount of cutting fluid and waste chips splashed from the machine tool will still remain in the guide groove 5710. By horizontally positioning the rotation axis of the first pulley 5200, the bottom of the first pulley 5200 abuts the top of the first translation guide rail 5600, achieving a sliding connection between the first protective door 5100 and the first translation guide rail 5600, while the second pulley 5300 rolls against the sidewalls of the guide groove 5710. This helps reduce translational resistance and prevents the second pulley 5300 from rolling against the bottom of the guide groove 5710, preventing waste chips and cutting fluid retained at the bottom of the guide groove 5710 from affecting the rolling motion of the second pulley 5300, further ensuring smooth opening and closing of the first protective door 5100.

[0072] Specifically, preferably, two first pulleys 5200 and two second pulleys 5300 are provided. The two first pulleys 5200 are provided on both sides of the top of the first protective door 5100 along the extension direction of the first translation guide rail 5600, and the two second pulleys 5300 are provided on both sides of the bottom of the first protective door 5100 along the extension direction of the second translation guide rail 5700. When the first protective door 5100 is closed, some waste chips and cutting fluid splashed in the direction of the first protective door 5100 will be The waste chips fall into the guide groove 5710 along the gap between the first protective door 5100 and the side wall of the guide groove 5710 and adhere to the side wall of the guide groove 5710. In order to prevent the waste chips attached to the side wall of the guide groove 5710 from affecting the rolling of the second pulley 5300 and the side wall of the guide groove 5710, the soft rubber scraper 5400 is respectively arranged at both ends of the second pulley 5300 along the extension direction of the guide groove 5710, so as to scrape off the waste chips and cutting fluid on the side walls of the guide groove 5710 at both ends of the second pulley 5300.

[0073] In addition, referring to Figures 4 and 6, in some embodiments of the present invention, a rotating shaft 5110 is provided at the bottom of the first protective door 5100, and the second pulley 5300 is rotatably connected to the rotating shaft 5110. The rotating shaft 5110 is vertically arranged, and the second pulley 5300 rotates around the rotating shaft 5110 to realize the rotational connection between the first protective door 5100 and the second translation guide rail 5710. The rotating shaft 5110 is preferably fixed to the bottom of the first protective door 5100 by bolts to facilitate replacement of the rotating shaft 5110 after the external impact on the first protective door 5100 causes the rotating shaft 5110 to be deformed.

[0074] 4 to 6 , in some embodiments of the present invention, in order to improve the chip removal efficiency of the guide groove 5710 and prevent the soft rubber scraper 5400 from wearing out too quickly due to scraping a large amount of waste chips each time during a long stroke, a plurality of chip removal holes 5720 connecting the guide groove 5710 and the machine tool are opened at the bottom of the guide groove 5710. The chip removal holes 5720 allow the waste chips and cutting fluid scraped by the soft rubber scraper 5400 in the guide groove 5710 to be quickly discharged into the bed 1000 of the machine tool, thereby reducing the wear of the soft rubber scraper 5400 and increasing its service life.

[0075] Furthermore, referring to FIG6 , in some embodiments of the present invention, the guide groove 5710 is provided with a plurality of drainage openings on the sidewall near the machine tool. Each drainage opening is connected to the chip removal hole 5720 , so that waste chips and cutting fluid scraped from the sidewall of the guide groove 5710 near the machine tool can fall directly from the drainage opening onto the machine tool bed 1000 , further enhancing the scraping effect. Furthermore, the distance between the top of the drainage opening and the bottom of the guide groove 5710 is less than the distance between the bottom of the second pulley 5300 and the bottom of the guide groove 5710 , thereby enhancing the rolling contact between the second pulley 5300 and the sidewall of the guide groove 5710 and preventing waste chips and cutting fluid remaining at the edge of the drainage opening from adhering to the second pulley 5300 .

[0076] Referring to Figure 4 , in some embodiments of the present invention, to facilitate the installation and fixation of the soft rubber scraper 5400, mounting ears 5120 are provided at the bottom of the first protective door 5100. The mounting ears 5120 are respectively arranged at both ends of the second pulley 5300 along the extension direction of the guide groove 5710, and the soft rubber scraper 5400 is fixedly connected to the mounting ears 5120. In addition, to clamp the soft rubber scraper 5400 and prevent excessive deformation of the soft rubber scraper 5400 and thus reduce the scraping effect, a clamping member 5500 is further provided on the side of the soft rubber scraper 5400 away from the mounting ears 5120. The clamping member 5500 engages with the mounting ears 5120 via screws to clamp and fix the soft rubber scraper 5400.

[0077] In order to prevent the vibration of the protective shell 4000 from causing high-frequency friction between the first pulley 5200 and the top of the first translation guide rail 5600 and thus wearing the first pulley 5200, an inwardly concave first annular groove is provided on the outer periphery of the first pulley 5200. The first pulley 5200 rolls and abuts against the top of the first translation guide rail 5600 through the first annular groove. The limiting cooperation between the first annular groove and the first translation guide rail 5600 avoids wear between the two due to vibration, thereby improving the connection stability and reliability.

[0078] In addition, in an embodiment of the present invention, the soft rubber scraper 5400 preferably adopts a silicone scraper that is more corrosion-resistant and oxidation-resistant to increase the service life of the soft rubber scraper 5400.

Specifically, the output end of the lifting cylinder 6100 is The output end 6110 moves toward and away from the material reclaiming opening 4200. When the output end 6110 of the lifting cylinder 6100 approaches the material reclaiming opening 4200, the second protective door 6200 connected to the output end 6110 closes the material reclaiming opening 4200. When the output end 6110 of the lifting cylinder 6100 moves away from the material reclaiming opening 4200, the second protective door 6200 connected to the output end 6110 opens the material reclaiming opening 4200, thereby achieving automated coordination of loading and unloading of materials on the machine tool. Specifically, the output end 6110 serves as the telescopic rod of the lifting cylinder 6100. The output end 6110 automatically retracts and extends, driving the second protective door 6200 to move up and down, thereby achieving automatic opening and closing of the material reclaiming opening 4200.

The rolling cooperation between the third pulley 6400 and the lifting guide rail 6300 effectively reduces the sliding friction between the second protective door 6200 and the two side walls of the groove 4300 when it is lifted or lowered, thereby improving the lifting smoothness.

[0082] Specifically, two rotating shafts 6230 are preferably provided on both sides of the second protective door 6200, and the two rotating shafts 6230 on each side are respectively arranged at the top and bottom of the inner side of the second protective door 6200. The third pulley 6400 on the top and bottom rotating shafts 6230 on each side is conducive to reducing the impact or friction between the second protective door 6200 and the side wall of the groove 4300 caused by the shaking when the second protective door 6200 is raised or lowered.

[0083] 8 , in some embodiments of the present invention, in order to avoid high-frequency collisions between the second protective door 6200 and the inner wall of the groove 4300 and high-frequency friction between the third pulley 6400 and the lifting guide rail 6300 caused by the vibration generated by the operation of the machine tool, the outer periphery of the third pulley 6400 is provided with a concave second annular groove 6410, and the third pulley 6400 rolls and abuts against the lifting guide rail 6300 through the second annular groove 6410. The engagement of the second annular groove 6410 and the lifting guide rail 6300 reduces the influence of the vibration of the machine tool operation on the second protective door 6200, thereby reducing the noise generated.

[0084] 7 and 8 , in some embodiments of the present invention, the lifting door assembly 6000 further includes a cylinder bracket 6500, the top of the cylinder bracket 6500 is connected to the protective shell 4000 at the top of the material taking port 4200, the outer side of the cylinder bracket 6500 is connected to the lifting cylinder 6100, and the outer side of the second protective door 6200 is provided with a lifting ear 6210 connected to the output end 6110. It can be understood that the lifting ear 6210 is provided at the bottom of the outer side of the second protective door 6200, and the installation position of the lifting cylinder 6100 is lowered, which can further reduce the height size of the compact machine tool structure of the present invention.

[0085] Referring to Figure 8, in some embodiments of the present invention, a baffle 6220 is provided at the bottom of the inner side of the second protective door 6200. The baffle 6220 passes through the material taking port 4200 and at least partially extends into the protective shell 4000. When closed, there will be a certain gap between the second protective door 6200 and the bottom of the material taking port 4200. The baffle 6220 can block the waste chips and cutting fluid splashing into the gap during processing in the machine tool, and prevent the waste chips and cutting fluid from falling outside the machine tool when the second protective door 6200 is opened.

[0086] Referring to Figure 8, the extended end of the baffle 6220 is provided with a bending portion 6221, which extends toward the bed 1000. The bending portion 6221 can accelerate the diversion of waste chips and cutting fluid that splash and adhere to the baffle 6220, effectively preventing the waste chips and cutting fluid attached to the baffle 6220 from falling outside the machine tool due to the opening action when the second protective door 6200 is opened, thereby improving the cleanliness of the external environment of the machine tool.

[0087] 9 , in some embodiments of the present invention, a first water channel 1200 is provided on the bed 1000 on both sides of the movement direction of the first translational slide mechanism 1100. The first water channel 1200 extends from the front end of the bed 1000 to the outside of the machine tool to drain cutting fluid and waste chips carried by the cutting fluid onto the bed 1000. The workbench includes: a workbench body 2000 having a second water channel 2100 on its top; first guide slopes 2200 provided on either side of the second water channel 2100, both facing the second water channel 2100; and first and second support bridges 2400, 2500, respectively, provided above both ends of the second water channel 2100. At least portions of the ends of the first support bridge 2400 are connected to the two first guide slopes 2200, and at least portions of the ends of the second support bridge 2500 are connected to the two first guide slopes 2200.

[0088] By the first guide bevels 2200 oppositely arranged on both sides of the second water guide groove 2100, the first guide bevels 2200 are arranged obliquely and extend from top to bottom toward the center of the second water guide groove 2100, and the second guide bevels 2300 are arranged obliquely and extend from top to bottom toward the outside of the second water guide groove 2100, thereby collecting the processing waste liquid through the first guide bevels 2200 and guiding the processing waste liquid to the outside of the workbench body 2000 through the second water guide groove 2100, so that the waste chips generated by the processing on the workbench can be easily dropped into the second water guide groove 2 100 so that the waste liquid can be discharged to the outside of the workbench body 2000 along the second water guide groove 2100, thereby preventing the waste chips accumulated on the workbench body 2000 from affecting the processing of the machine tool. The first support bridge 2400 and the second support bridge 2500 are respectively arranged above the second water guide groove 2100 through the first guide slope 2200 of the connecting beam, which effectively reduces the height of the workbench and realizes the miniaturization of the workbench. The first guide slope 2200 is arranged at an angle and extends from top to bottom toward the outside of the workbench body 2000, which is conducive to discharging the processing waste liquid outward.

[0089] Specifically, the outflow end of the second water guide groove 2100 is located above the first water guide groove 1200 on the side of the first translational slide rail mechanism 1100 so as to collect waste chips and cutting fluid flushed out of the second water guide groove 2100 .

[0090] In addition, a plurality of flushing nozzles for spraying cutting fluid are provided in the protective cover, and the plurality of flushing nozzles are respectively directed toward the inner wall of the protective shell 4000, the first water guide groove 1200 and the worktable body 2000, so that when the machine tool is working, the sprayed cutting fluid can accelerate the waste chips splashed and attached to the inner wall of the protective shell 4000, the first water guide groove 1200 and the worktable body 2000 to fall and be discharged outside the machine tool, thereby preventing excessive accumulation of waste chips inside the machine tool.

[0091] 10 and 11 , in some embodiments of the present invention, in order to further improve the chip removal efficiency of the second water guide groove 2100, second guide slopes 2300 are provided at both ends of the bottom of the second water guide groove 2100. The two second guide slopes 2300 are respectively inclined outwards toward the two ends of the second water guide groove 2100. Driven by the cutting fluid flow and under the action of gravity, waste chips can be quickly removed from the second slopes at both ends of the second water guide groove 2100.

[0092] 11 , the first support bridge 2400 and the second support bridge 2500 are respectively arranged above the two second guide slopes 2300 so that waste chips splashed onto the first support bridge 2400 and the second support bridge 2500 during processing can directly fall onto the second guide slopes 2300, thereby reducing the residence time of the waste chips in the second water guide trough 2100.

[0093] In order to prevent the waste chips splashed onto the first support bridge 2400 and the second support bridge 2500 during processing from accumulating on the first support bridge 2400 and the second support bridge 2500, both ends of the first support bridge 2400 are provided with third guide slopes 2410, and the two third guide slopes 2410 are inclined outwardly toward the two sides of the second water guide groove 2100, and both ends of the second support bridge 2500 are provided with fourth guide slopes 2510, and the two fourth guide slopes 2510 are inclined outwardly toward the two sides of the second water guide groove 2100, and the two ends of the second water guide groove 2100 of the workbench body 2000 are located on the first water guide groove 1200, then the first support bridge 2400 and the second support bridge 2500 are respectively located above the two first water guide grooves 1200, so that the third guide slopes 2410 and the fourth guide slopes 2510 are inclined outwardly toward the two sides of the second water guide groove 2100. The washed-down waste chips directly fall into the two first water guide grooves 1200 , preventing the waste chips from falling onto the first translation slide rail mechanism 1100 and affecting the translation of the workbench.

[0094] Specifically, returning to Figure 9, the workbench also includes: a five-axis turntable 2600 disposed on the first support bridge 2400; a tailstock 2700 disposed on the second support bridge 2500; and a bridge plate 2800 disposed above the second water guide trough 2100. The tops of the two ends of the bridge plate 2800 are respectively provided with a first connecting seat and a second connecting seat. The bridge plate 2800 is driven and connected to the five-axis turntable 2600 through the first connecting seat, and the bridge plate 2800 is rotatably connected to the tailstock 2700 through the second connecting seat. The bridge plate 2800 between the five-axis turntable 2600 and the tailstock 2700 is turned by the five-axis turntable 2600, so that the spindle assembly 3000 can process the workpiece fixed to the bridge plate 2800.

[0095] 12 and 13 , the shoe mold machine tool according to the present invention performs multi-axis coordinated machining of a shoe mold workpiece (or blank) clamped on the five-axis turntable 2600 of the worktable body 2000 via the spindle assembly 3000. In some embodiments, the control method for the shoe mold machine tool according to the present invention may include the following steps for machining the shoe mold workpiece:

[0096] S100, obtaining the relative position between the spindle assembly and the shoe mold workpiece, and receiving a processing instruction input by a user for the shoe mold workpiece;

[0097] S200, importing regional position data of multiple to-be-processed parts of a shoe mold workpiece, and obtaining a maximum processing feed speed to be implemented for each to-be-processed part based on the regional position data of each to-be-processed part;

[0098] S300, when it is determined that the maximum machining feed rate to be implemented of a target portion to be machined exceeds the maximum machining feed rate to be implemented of any other portion to be machined to reach a threshold, dynamically modifying the machining instruction to reduce the maximum machining feed rate to be implemented of the target portion to be machined;

[0099] S400 , planning motion control instructions according to the processing instructions of the various parts to be processed of the shoe mold workpiece, so as to trigger the coordinated motion of the spindle assembly and the worktable to process the shoe mold workpiece.

[0100] For step S100, before processing the shoe mold workpiece, it is necessary to obtain the relative position of the spindle assembly and the shoe mold workpiece on the five-axis turntable 2600. For example, the end of the spindle assembly can be driven to the process positioning point of the shoe mold workpiece, and the position of the spindle assembly relative to the machine tool coordinate system at this time is recorded. Since the process positioning point is pre-processed on the shoe mold workpiece, its position is directly related to the shape and position (shape position) parameters of the shoe mold workpiece. Then, the control system of the machine tool receives the model data of the shoe mold workpiece and the processing instructions and process parameters of the target shape to be processed. The model data can be 3D model data of the target shape of the shoe mold workpiece, in which a plurality of parts to be processed are divided. In a specific example, the plurality of parts to be processed of the shoe mold workpiece include at least the sole part JZ, the heel part GE and the arch part GO.

[0101] For step S200, the maximum processing feed speed is calculated for each part to be processed based on the processing type or method (e.g., rough milling, fine milling, grinding) input by the machine tool user and the desired processing speed input by the user. Preferably, the maximum processing feed speed of each part to be processed is obtained by classification for each processing type or method, so as to be used for subsequent planning of the processing speed. In a specific example, the regional position data of the multiple parts to be processed of the shoe mold workpiece can be divided into the positions of the sole area, the heel area and the arch area. For example, after receiving the rough milling instruction input by the user, the maximum feed speeds for rough milling and fine milling are obtained in the sole area, the heel area and the arch area respectively, so as to meet the processing efficiency and precision requirements of rough milling and fine milling of the shapes of each area.

[0102] For step S300, based on the maximum machining feed rate of each to-be-machined part obtained in the previous step (set as V1), the difference (V1-V2) is calculated based on the maximum machining feed rate of the target machining part and the maximum machining feed rate of other to-be-machined parts (set as V2). If the difference exceeds the threshold (set as V T ), then reduce the maximum machining feed speed V1 of the target part to be processed, generally making V1 dynamically reduced to 1V T to 1.5V T Threshold V TIt is generally between 1.2V2 and 2V2, and varies according to the type of processing. The higher the precision of the processing type (for example, fine milling requires higher precision than rough milling), the smaller the threshold. In the processing scenario of shoe mold workpieces, the curvature and straightness of the processing routes of different processing parts vary greatly. In a preferred embodiment, the average curvature of the feed trajectory in the processing area of ​​each part to be processed can be determined. If the average curvature of the target area is smaller, under the same processing type, the threshold is made smaller, which can limit the processing part or area from feeding too fast. In addition, the threshold can be obtained through machine learning methods based on the historical processing records of the machine tool.

[0103] As shown in Figures 12 and 13, in a specific embodiment, the shoe mold processing primarily processes the sole contour and pattern. The sole JZ and heel GE are primarily patterned for anti-slip performance, and the sole JZ has a relatively large number of flat surfaces. When processing the sole JZ and heel GE, the numerous patterns require the three axes of the shoe mold machine to continuously accelerate and decelerate, resulting in a low processing speed, generally within the feed rate of (CNC code) F2000. When processing the arch GO, which is essentially a flat surface or a small arc, the spindle assembly has ample room to accelerate to the programmed feed rate of (CNC code) F6000. In this example, if the spindle speed remains constant throughout the entire processing process, the cutting linear speeds of the sole, heel, and arch will be inconsistent, resulting in the arch being rougher than the sole and heel, and the knife marks being heavier. Therefore, after calculating the maximum feed rate for the sole JZ and heel GE, the maximum feed rate for machining the arch GO is limited to no more than 1.2 times the maximum feed rate for the sole JZ or heel GE to resolve the aforementioned problem of inconsistent tool marks caused by inconsistent machining speeds across the shoe mold workpiece. Alternatively, machine learning methods can be used to calculate the maximum feed rate for the sole JZ and heel GE of the current shoe mold workpiece from historical data on machining shoe mold workpieces of the same type and other specifications (different shoe sizes) (for example, the maximum feed rate for a smaller shoe mold workpiece is slightly lower than that for a larger shoe mold workpiece).

[0104] The above description is merely a preferred embodiment of the present invention. The present invention is not limited to the aforementioned embodiments. As long as the technical effects of the present invention are achieved by the same means, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure. Within the scope of protection of the present invention, its technical solutions and / or implementation methods may be modified and varied in various ways.
