Description

Technical Field

[0001] The present invention relates to the technical field of production and processing, and in particular to a five-star foot production and processing technology and processing equipment. Background Art

[0002] The detachable foot assembly is a furniture component that is easy to disassemble and install, and is mainly used as a supporting structure for furniture such as chairs. The detachable foot assembly usually consists of a five-star foot and a number of tubular detachable feet that are connected front to back. The five-star foot includes a cylindrical fixing sleeve and a number of hollow tubular mounting feet. The detachable foot sleeve is arranged on the other end of the mounting foot and is detachably fixed to the mounting foot. This structure makes the detachable foot easy to disassemble and transport.

[0003] The traditional processing technology of five-star feet usually involves manually placing the insert in the mold cavity, then using an injection molding machine to perform injection molding. After molding, the workpiece is manually removed from the mold, and the remaining waste is manually cut off, and finally the material is cut out manually.

[0004] The above conventional technical means have a low degree of automation and low production efficiency, especially in the steps of insert placement and workpiece cutting and cooling. Frequent manual operations lead to long processing cycles and it is difficult to ensure the precise matching and positioning of the workpiece and the insert during the process. Summary of the invention

[0005] In view of this, the present application provides a five-star foot production and processing technology and five-star foot production and processing equipment, which are convenient for reducing processing costs and improving processing efficiency.

[0006] In a first aspect, the present application provides a five-star foot production and processing process for processing a workpiece into a five-star foot, the processing process comprising the following steps: Take the insert: The grabbing device grabs the insert from the insert feeding station; Placing the insert: the gripping device places the insert into the front mold of the mold cavity of the injection molding machine; Taking the workpiece: the grabbing device moves to the rear mold in the opposite direction of the insert placement, and takes the workpiece out of the rear mold; Punching: The gripping device places the workpiece in the punching station and shears the waste from the center hole of the workpiece; Cooling: The gripping device places the workpiece at the shearing station into a cooling station in the cooling zone; Reaming: The gripping device places the workpiece at the cooling station at the reaming station to ream the center hole, and processes the workpiece into a five-star foot; Unloading: The grabbing device places the five-star foot of the reaming station at the unloading station; Among them, when the grasping device grasps the workpiece and the workpiece is placed in the punching station, the five-claw shape of the workpiece is used for positioning, and when the workpiece is placed in the reaming station, the five-claw shape and the center hole are used for positioning.

[0007] By adopting the technical solution of the present application, the whole process of automated operation from insert placement, workpiece removal, punching, cooling, reaming to cutting is realized. This not only reduces the frequency of manual participation, but also avoids the errors and inefficiencies caused by manual operation, thereby greatly improving the degree of automation in the production of five-star feet. In the processing technology, especially when grabbing the workpiece and placing it in the punching station and reaming station, the five-claw shape and center hole of the workpiece are used for positioning. This dual positioning method ensures the stability and accuracy of the workpiece during the processing, avoids processing errors caused by workpiece movement or misalignment, and thus improves the processing quality and consistency of the five-star feet. The five-star foot production and processing technology and production and processing equipment provided by the present application achieve a significant improvement in production efficiency, stability in processing quality, and reduction in processing costs through technical features such as automated operation and precise positioning, providing a more efficient, stable and flexible solution for the production of five-star feet.

[0008] In some embodiments, after the five-star foot is placed in the cooling station, the cooling station sinks to a certain height until the number of workpieces placed in the cooling station reaches a set number.

[0009] By adopting the above technical solution, the design of sinking the cooling station allows more workpieces to be stacked for cooling in a limited space. The sinking of the station can make room for subsequent workpieces without adding additional floor space. This design improves the space utilization of the production area, making the entire production line more compact and efficient. By stacking the workpieces for cooling, the temperature distribution of the cooling zone can be more effectively utilized. The stacking design can also achieve full contact between the workpiece and the air, improving the cooling efficiency to a certain extent. The design of sinking the cooling station is coordinated with the automated gripping device. When the gripping device places the workpiece in the cooling station, the cooling station sinks to facilitate the next workpiece placement, further optimizing the automation level of the entire production process and improving the overall fluency and efficiency of the production line.

[0010] In some embodiments, the five-star foot is placed in the cooling station and positioned using the center hole and single-claw shape of the workpiece.

[0011] By adopting the above technical solution, during the cooling process, due to the characteristics of thermal expansion and contraction of the material, the five-star foot may be deformed to a certain extent. The use of center hole and single-claw shape positioning can effectively reduce this deformation. Center hole positioning can limit the shrinkage of the center hole of the five-star foot, while single-claw shape positioning can inhibit deformation to a certain extent and facilitate the release of internal stress during the cooling process, thereby improving the dimensional accuracy and shape stability of the five-star foot after cooling. Due to accurate and stable positioning, the gripping device can place the five-star foot on the cooling station more quickly and continue to perform the next task. This reduces the residence time of the gripping device at the cooling station and improves the production efficiency of the entire production line. The center hole and single-claw shape positioning methods are consistent with punching and reaming, which can improve the positioning consistency and accuracy of the five-star foot in different processes and reduce the positioning error in different processes.

[0012] In some embodiments, when the five-star foot is removed from the cooling station, the station is raised to a certain height.

[0013] By adopting the above technical solution, when the five-star foot is removed, the cooling station rises to a certain height, which can ensure the consistency of the height of the top five-star foot, facilitate the consistency of the grasping position of the grasping device, and improve the accuracy and efficiency of grasping.

[0014] In some embodiments, after the cooling station has placed a set number of the workpieces, the cooling station rotates in the cooling zone to continuously change the position and angle of the workpiece relative to the cooling source.

[0015] By adopting the above technical solution, the workpiece can be cooled more evenly, thereby reducing the deformation problem caused by uneven cooling, and helping to improve the dimensional accuracy and shape stability of the workpiece. Constantly changing the relative position and angle between the workpiece and the cooling source can ensure that the cooling source can act more effectively on various parts of the workpiece, thereby improving the cooling efficiency, helping to shorten the cooling time and improve the overall efficiency of the production line.

[0016] In some embodiments, the cooling station revolves about a center of a circle, and the workpiece rotates relative to the station.

[0017] By adopting the above technical solution, cooling is more uniform and the cooling efficiency is higher.

[0018] In the second aspect, the present application provides a five-star foot production and processing equipment, which adopts the five-star foot production and processing process of the first aspect to process the workpiece into a five-star foot, and the processing equipment includes a cooling device, a punching device and a reaming device. The cooling device includes a cooling table, a cooling column fixedly connected to the cooling table, and a lifting mechanism. The cooling column is slidably connected to a cooling plate, and the lifting mechanism can drive the cooling plate to slide along the cooling column.

[0019] In some embodiments, the cooling device includes a rotating turntable and a refrigeration assembly, and a plurality of cooling plates for placing workpieces are distributed circumferentially along the rotation center of the turntable, and the position and angle of the cooling plates relative to the refrigeration assembly change as the turntable rotates.

[0020] Through the design of a rotating turntable, refrigeration components and multiple cooling plates distributed circumferentially along the rotation center, efficient, uniform and automatic cooling of the workpiece is achieved, improving the space utilization, adaptability and economic benefits of the production line.

[0021] In some embodiments, the cooling column is a hollow circular tube structure, with one end of the cooling column away from the cooling table being closed and the other end close to the cooling table being connected to the cooling hole on the cooling table, the cooling hole passing through the upper and lower surfaces of the cooling table, the cooling plate being connected to a driving member, and the driving member driving the cooling plate to slide in the height direction relative to the turntable.

[0022] By adopting the above technical solution, the cooling column can cool the center hole of the five-star foot, and the sliding of the cooling plate can achieve the consistent height of the top five-star foot, which facilitates the consistency of the grasping position of the grasping device and improves the accuracy and efficiency of grasping.

[0023] In some embodiments, the cooling device is provided with a sensor. When the sensor senses that a workpiece is placed on the cooling plate, the sensor transmits a signal to the driving member, and the driving member drives the cooling plate to move a distance closer to the turntable; when the sensor senses that the workpiece on the cooling plate is reduced, the driving member drives the cooling plate to move a distance away from the turntable.

[0024] By adopting the above technical solution, the sensor can sense the placement status of the workpiece on the cooling plate in real time and transmit the signal to the drive. This automated sensing and response mechanism reduces the need for manual intervention and improves the intelligence level of the production line. When the sensor senses the placement of the workpiece, the drive automatically adjusts the height of the cooling plate to ensure the height consistency of the workpiece, thereby improving the consistency and efficiency of the grasping. Similarly, when the workpiece is removed, the cooling plate will automatically adjust its height to prepare for the placement of the next workpiece.

[0025] In summary, the present application has at least one of the following beneficial technical effects: 1. The five-star foot production and processing technology provided in this application achieves a significant improvement in production efficiency, stability in processing quality, and reduction in processing costs through automated operation and precise positioning, providing a more efficient, stable, and flexible solution for the production of five-star feet.

[0026] 2. The five-star feet are placed on the cooling station, punching and reaming stations using the center hole and single-claw shape positioning method, which can enhance the positioning consistency and stability, improve production efficiency and adapt to the needs of five-star feet of different specifications.

[0027] 3. The cooling device in the five-star foot production and processing equipment provided by the present application realizes efficient, uniform and automatic cooling of the workpiece through the design of a rotating turntable, a refrigeration component and a plurality of cooling plates distributed along the circumference of the rotation center, thereby improving the space utilization, adaptability and economic benefits of the production line. 4. The design of setting up sensors and driving the cooling plate to move relative to the turntable according to the sensor signal brings many advantages such as automation, intelligence, high efficiency, energy saving, flexibility and safety to the cooling device of the five-star foot production and processing equipment.

[0034] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0035] Embodiment 1 See also Figure 1 The present application provides a five-star foot production and processing process, which includes the following steps: Retrieving the insert: The gripping device grabs the insert from the insert feeding station. The gripping device here can be a manipulator or other forms of automatic gripping equipment. The insert feeding station can be a vibrating plate or other device that can automatically sort and transport the inserts. The gripping device firmly grabs the insert by means of suction cups or clamps.

[0036] Insert placement: The gripping device places the insert into the front mold of the mold cavity in the injection molding machine. The mold of the injection molding machine is divided into a front mold and a back mold. The front mold is equipped with an insert positioning groove to ensure the precise positioning of the insert. The insert positioning groove can fix the insert through magnets, springs or other physical methods to prevent displacement during the injection molding process.

[0037] Take the workpiece: The gripping device moves to the rear mold in the opposite direction of the insert placement and takes the workpiece out of the rear mold. The rear mold is equipped with a workpiece positioning groove to ensure the precise positioning of the workpiece. The design of the workpiece positioning groove can be adjusted according to the shape and size of the workpiece.

[0038] Punching: The gripping device places the workpiece in the punching station to shear the waste from the center hole of the workpiece. The punching station can be a mechanical device with a punch, which is driven by air pressure or hydraulic pressure to shear the workpiece. A guide device can be set on the punch to ensure the shearing accuracy. In addition, the punching station can also be equipped with a waste collector to automatically collect the sheared waste to avoid polluting the working environment.

[0039] Cooling: The gripping device places the workpieces from the shearing station at the cooling station in the cooling zone. The cooling station can be a turntable with a refrigeration component, on which a plurality of cooling plates are arranged. The cooling plates can be slidably connected to the turntable and slide in the height direction through the driving member to adapt to different numbers of workpieces.

When the five-star foot is placed at the cooling station, the cooling station sinks to a certain height until the number of workpieces placed at the cooling station reaches the set number. After the number of workpieces placed at the cooling station reaches the set number, the cooling station rotates in the cooling zone to continuously change the position and angle of the workpiece relative to the cooling source. The five-star foot is placed at the cooling station and is positioned by the center hole and single claw shape of the workpiece. When the five-star foot is removed from the cooling station, the station rises to a certain height. The cooling station revolves relative to a center of a circle, and the workpiece rotates relative to the station.

[0040] Reaming: The gripping device places the workpiece in the cooling station in the reaming station to ream the center hole and process the workpiece into a five-star foot. The reaming station can be a mechanical device with a reamer, which is driven by a motor to rotate and fine-process the center hole of the workpiece. The reaming station can also be equipped with a detection device to monitor the accuracy of the reaming in real time to ensure product quality.

[0051] The implementation principle of the reaming device 3 is as follows: by setting a lateral sliding clamp 38 and a longitudinal sliding reamer 39, accurate positioning and efficient processing of the center hole of the five-star foot are achieved. The adjustment function of the clamp 38 enables the device to adapt to five-star feet of different sizes, improving the versatility and flexibility of the equipment. The dual-drive design of the drive assembly enables the reamer 39 to move longitudinally and synchronously drive the reamer 39 to rotate in the process of approaching the five-star foot, thereby achieving efficient cutting processing. The elastic connection design of the pressure ring 352 further improves the processing accuracy and reduces the impact of vibration on the processing quality. In general, the five-star foot reaming device 3 of this embodiment has significant advantages in improving processing accuracy and efficiency, and can meet the high-precision requirements of mass production.

[0064] The cooling device 4 is cooled by an air cooling system, which includes an air cooler 49 and an air duct, and is used to assist the coolant circulation system to further improve the cooling efficiency.

[0065] Specifically, the cooling fan 49 can be a centrifugal fan or an axial flow fan, which is used to generate high-speed airflow and blow the cooling air evenly to the five-star foot through the air outlet 461. The air duct can be a pipe made of aluminum or stainless steel, which is used to guide the direction and speed of the cooling air.

The design of the air cooling system can ensure the uniform distribution and high-speed flow of cooling air, effectively remove the heat from the surface of the five-star foot and speed up the cooling speed. This design not only improves the cooling quality, but also effectively responds to emergencies in the production process and improves the reliability and stability of production.

[0068] Working principle of cooling device 4: cooling device 4 can realize efficient cooling of five-star feet through the coordinated action of cooling table 41, cooling column 46 and lifting mechanism 44. When cooling table 41 rotates, two lifting mechanisms 44 correspond to cooling plates 43 located at material taking station 413 and material discharging station 412, and lifting mechanism 44 drives cooling plates 43 to move up and down along cooling column 46.

The cooling holes on cooling table 41 and the cooling channels in cooling column 46 can guide the cooling medium to be evenly distributed, accelerating the cooling process of five-star feet. Precise control of lifting mechanism 44 can ensure the smooth sliding of cooling plate 43 and prevent the five-star feet from being damaged during the cooling process. The setting of the material discharge sensor 42 and the material pick-up sensor 45 can monitor the state of the five-star foot in real time to ensure the continuity and stability of the production process.

[0070] Embodiment 3 See also Fig.16 The difference between this embodiment and the second embodiment is that the cylinder 26 is connected to a booster cylinder 27 and a pressure gauge 28. The booster cylinder 27 is used to increase the driving force of the cylinder 26, so that the cutter 22 is more powerful when cutting hard materials. The pressure gauge 28 is used to monitor the pressure value of the cylinder 26 in real time to ensure that the cylinder 26 works within a safe range.

[0071] The air cylinder 26 is a double-acting air cylinder 26 with stable thrust and fast response speed. The booster cylinder 27 is installed on the air inlet pipeline of the air cylinder 26, and the working pressure of the air cylinder 26 is adjusted by the booster valve. The pressure gauge 28 is installed at the air outlet of the booster cylinder 27 to display the actual working pressure of the air cylinder 26. The combination of the booster cylinder 27 and the pressure gauge 28 enables the cutter 22 to always maintain sufficient force during the cutting process, and can easily cope with even harder materials.

[0072] The implementation principle of this embodiment is: when it is necessary to cut the waste material of the five-star foot nozzle, firstly, the pressure of the cylinder 26 is adjusted by the booster cylinder 27 according to the thickness and hardness of the five-star foot, and the pressure gauge 28 displays the actual working pressure of the cylinder 26 to ensure the safety and reliability of the processing process. Adjusting the appropriate cutting pressure according to the different parameters of the five-star foot can better achieve a balance between cutting efficiency and cutting quality.
