Description

Technical Field

[0001] This utility model relates to the field of stainless steel tableware processing technology, specifically to a multi-station embossing structure for stainless steel tableware. Background Technology

[0002] Stainless steel tableware is a stainless steel product made of chromium-nickel alloy. It has the characteristics of not rusting and corrosion resistance. For example, when making stainless steel plates, the surface of the stainless steel plates needs to be embossed.

[0003] In the traditional embossing structure, the worker places the stainless steel plate in the lower mold, and then drives the upper mold to move through the hydraulic cylinder, thereby embossing the surface of the stainless steel plate.

[0004] However, since the upper and lower molds are fixed in size, they can only be used to emboss stainless steel plates of the same type. If embossing is required for plates of different sizes and shapes, the entire set of molds needs to be replaced. Moreover, during the mold replacement process, the upper and lower molds need to be repositioned and adjusted, which is troublesome and time-consuming, thus reducing the effectiveness of the internal molds in the embossing structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a multi-station embossing structure for stainless steel tableware. This solves the problem that because the upper and lower molds are of fixed size, they can only be used to emboss the same type of stainless steel plates. If embossing is required for plates of different sizes and shapes, the entire set of molds needs to be replaced, which is troublesome and time-consuming, thus reducing the effectiveness of the internal molds in the embossing structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station embossing structure for stainless steel tableware, comprising a base box, with a lower mold and an upper mold respectively disposed on the top of the base box. Placement grooves are respectively formed on the surfaces of the lower mold and the upper mold, with a lower mold core and an upper mold core inserted into the inner wall of each placement groove. Horizontal grooves are formed on the surfaces of the lower mold and the upper mold, communicating with the placement grooves. Horizontal columns are fixedly connected to the side walls of the lower mold core and the upper mold core, with the outer wall of each horizontal column inserted into the inner wall of the horizontal groove. Positioning holes are formed on the surface of the horizontal groove, and positioning protrusions are fixedly connected to the outer walls of each horizontal column. The outer walls of the positioning protrusions are inserted into the inner walls of the positioning holes. Bolts penetrate the inner walls of the lower mold, the upper mold, and the horizontal columns, with nuts threaded onto the outer walls of the ends of the bolts.

[0007] Preferably, a controller is fixedly connected to the front of the base box.

[0008] Preferably, a frame is fixedly attached to the surface of the base box, a reinforcing rib is fixedly connected to the upper part of the outer wall of the frame, an outer shell is fixedly connected to the top of the frame by screws, a hydraulic cylinder is fixedly connected to the upper part of the inner wall of the outer shell by screws, the bottom output end of the hydraulic cylinder extends to the bottom of the frame through an opening, and the bottom output end of the hydraulic cylinder is fixedly attached to the top of the upper mold by screws.

[0009] Preferably, a support column is fixed to the side of the base box away from the frame, a support plate is fixed to the top of the support column, a motor is fixed to the bottom of the support plate by screws, a rotating shaft is fixed to the output end of the motor, the outer wall of the rotating shaft is rotatably connected to the inner wall of the support plate by bearings, a turntable is fixed to the top of the rotating shaft, and the surface of the turntable is fixed to the bottom of the lower mold by screws.

[0010] Preferably, the surface of the support plate is provided with a groove, and a slider is slidably engaged with the outer wall of the groove. The outer wall of the slider is fixed to the bottom of the turntable. Beneficial effects

[0011] This utility model provides a multi-station embossing structure for stainless steel tableware. It offers the following advantages: This multi-station embossing structure, through the cooperation of placement grooves, horizontal grooves, horizontal columns, bolts, nuts, positioning holes, and positioning protrusions, allows for embossing of stainless steel plates of different sizes and shapes by replacing the lower and upper mold cores. This solves the problem that because the upper and lower molds are of fixed sizes, they can only emboss the same type of stainless steel plate. If embossing of plates of different sizes and shapes is required, the entire set of molds needs to be replaced, which is cumbersome and time-consuming, thus reducing the effectiveness of the internal molds in the embossing structure.

[0012] By coordinating the support columns, support plates, motors, rotating shafts, slides, sliders, and turntables, multi-station embossing processing of stainless steel plates is achieved. This solves the problem that in most cases, only one plate can be embossed at a time during the embossing process of stainless steel plates. After the plate is embossed, the machine needs to be stopped to remove the finished product and place a new workpiece, resulting in a long downtime for the entire process and thus reducing the efficiency of stainless steel plate embossing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Since the upper and lower molds are of fixed size, they can only be used to emboss stainless steel plates of the same type. If embossing is required for plates of different sizes and shapes, the entire set of molds needs to be replaced, which is troublesome and time-consuming, thus reducing the effectiveness of the molds inside the embossing structure.

[0021] In view of this, the present invention provides a multi-station embossing structure for stainless steel tableware. Through the cooperation between the placement groove, horizontal groove, horizontal column, bolt, nut, positioning hole and positioning protrusion, it realizes the embossing processing of stainless steel plates of different sizes and shapes by replacing the lower mold core and the upper mold core. This solves the problem that since the upper and lower molds are fixed in size, they can only be used to emboss the same type of stainless steel plates. If it is necessary to emboss plates of different sizes and shapes, the entire set of molds needs to be replaced, which is troublesome and time-consuming, thus reducing the effectiveness of the internal molds of the embossing structure.

[0022] Those skilled in the art will connect the electrical components and their compatible power supplies in this case using wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle below, where the electrical components are connected in the order of operation. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control.

[0023] Example 1, by Figure 1-5 It is understood that the multi-station embossing structure of stainless steel tableware in this case includes a base box 1. A lower mold 3 and an upper mold 5 are respectively provided on the upper part of the base box 1. Placement grooves 7 are respectively opened on the surface of the lower mold 3 and the upper mold 5. The lower mold core 4 and the upper mold core 6 are respectively inserted into the inner wall of the placement groove 7. The surface of the lower mold 3 and the upper mold 5 are provided with a horizontal groove 8, which is connected to the placement groove 7. The side walls of the lower mold core 4 and the upper mold core 6 are respectively fixed with a horizontal column 9. The outer wall of the horizontal column 9 is inserted into the inner wall of the horizontal groove 8. The surface of the horizontal groove 8 is provided with a positioning hole 12. The outer wall of the horizontal column 9 is fixedly connected with a positioning protrusion 13. The outer wall of the positioning protrusion 13 is inserted into the inner wall of the positioning hole 12. Bolts 10 are respectively passed through the inner walls of the lower mold 3, the upper mold 5 and the horizontal column 9. Nuts 11 are threadedly connected to the outer wall of the end of the bolt 10.

[0024] In the specific implementation process, it is worth noting that there are two lower molds 3 and two lower mold cores 4. When embossing the stainless steel plate, the worker places the stainless steel plate in the cavity on the surface of the lower mold core 4, and then moves the upper mold 5 to drive the upper mold core 6. Through the cooperation of the upper mold core 6 and the lower mold core 4, the stainless steel plate is embossed. After embossing, the worker removes the stainless steel plate from the lower mold core 4, completing the embossing process. When embossing stainless steel plates of different sizes and shapes, the worker rotates the corresponding nuts 11 in sequence to unscrew the bolts 10. Then, the worker removes the bolts 10 from the lower mold 3, the upper mold 5, and the cross post 9, releasing the fixation of the lower mold core 4 and the upper mold core 6. After the mold is removed from the placement slot 7, the staff inserts the lower mold core 4 and upper mold core 6, which match the shape and size of the stainless steel plate to be processed, into the placement slot 7. At the same time, the lower mold core 4 and upper mold core 6 drive the horizontal column 9 to move, and the horizontal column 9 is inserted into the horizontal slot 8. The horizontal column 9 drives the positioning protrusion 13 to move, and the positioning protrusion 13 is inserted into the positioning hole 12 to position the lower mold core 4 and upper mold core 6. Finally, the staff re-insert the bolt 10 into the lower mold 3, upper mold 5 and horizontal column 9 in sequence, and rotate the nut 11 back onto the bolt 10 to fix the replaced lower mold core 4 and upper mold core 6, so as to perform embossing processing on stainless steel plates of different sizes and shapes. This allows for the embossing processing of stainless steel plates of different sizes and shapes by replacing the lower mold core 4 and upper mold core 6.

[0025] Furthermore, a controller 2 is fixedly connected to the front of the base box 1;

[0026] In the specific implementation process, it is worth noting that the controller 2 is model S7-1200. The controller 2 and the base box 1 can be connected by screws. The staff can disassemble and reassemble the controller 2 by turning the screws, so as to inspect and maintain the controller 2. The staff can control the whole equipment through the controller 2 to automatically emboss the stainless steel plate.

[0027] Furthermore, a frame 14 is fixedly attached to the surface of the base box 1, a reinforcing rib 15 is fixedly connected to the upper part of the outer wall of the frame 14, an outer shell 16 is fixedly connected to the top of the frame 14 by screws, a hydraulic cylinder 17 is fixedly connected to the upper part of the inner wall of the outer shell 16 by screws, the bottom output end of the hydraulic cylinder 17 extends to the bottom of the frame 14 through an opening, and the bottom output end of the hydraulic cylinder 17 is fixedly attached to the top of the upper mold 5 by screws.

[0028] In the specific implementation process, it is worth noting that the frame 14 is the main supporting structure of the equipment. The reinforcing ribs 15 are welded to the frame 14. Based on mechanical principles, this increases the structural strength and stability of the frame 14 when bearing the downward load of the hydraulic cylinder 17, preventing deformation or cracking of the frame 14 due to long-term stress. Workers can disassemble and reassemble the outer casing 16 by turning the screws on it, thereby allowing for inspection and maintenance of the hydraulic cylinder 17. Heat dissipation holes and wiring ports can be opened on the outer wall of the outer casing 16. The heat dissipation holes dissipate heat from the hydraulic cylinder 17, and the wiring ports facilitate wiring to the hydraulic cylinder 17. The model of the hydraulic cylinder 17 is P1D-. In C050MS-0300, the connection between hydraulic cylinder 17 and controller 2 is as follows: the digital output module of controller 2 is isolated by relays and contactors to drive the proportional valve of hydraulic cylinder 17, controlling the extension, retraction, and pressure holding actions. The displacement sensor and pressure sensor of hydraulic cylinder 17 output 4-20mA analog signals, which are connected to the analog input module of controller 2 to provide feedback on piston position and embossing pressure. Based on the displacement sensor data, controller 2 adjusts the opening of the proportional valve using a PID algorithm to achieve closed-loop position control. When the pressure exceeds the threshold, the digital output is triggered to cut off the power supply to the proportional valve to ensure equipment safety and achieve precise and stable control of the embossing process.

[0029] When embossing is performed, the staff starts the hydraulic cylinder 17 through the controller 2. The hydraulic cylinder 17 drives the upper mold 5 to move, and the upper mold 5 drives the upper mold core 6 to move, thereby embossing the stainless steel plate. After embossing is completed, the controller 2 causes the hydraulic cylinder 17 to retract, thereby returning the upper mold core 6 to the initial position. The controller 2 stops the hydraulic cylinder 17 from working, thus driving the upper mold core 6 to move.

[0030] Of course, the hydraulic cylinder 17 can be replaced by an electric push rod, and its specific model is not limited, as long as it meets the technical solution described in this embodiment, or other feasible means can be used to drive the upper mold core 6 to move.

[0031] Example 2, by Figure 1 , 2 As shown in Figure 5, a support column 18 is fixedly connected to the side of the bottom box 1 away from the frame 14. A support plate 19 is fixedly connected to the top of the support column 18. A motor 20 is fixedly connected to the bottom of the support plate 19 by screws. A rotating shaft 21 is fixedly connected to the output end of the motor 20. The outer wall of the rotating shaft 21 is rotatably connected to the inner wall of the support plate 19 by bearings. A turntable 24 is fixedly connected to the top of the rotating shaft 21. The surface of the turntable 24 is fixedly connected to the bottom of the lower mold 3 by screws.

[0032] In the specific implementation process, it is worth noting that the support column 18 and the support plate 19 provide a stable support foundation for the rotation of the turntable 24 and the lower mold 3. The model of the motor 20 is MSMF042L1UM. The connection between the motor 20 and the controller 2 is as follows: the high-speed pulse output port of the controller 2 is connected to the pulse input interface of the servo driver. The controller 2 controls the rotation angle and speed of the motor 20 by outputting a certain number and frequency of pulse signals. The digital output port of the controller 2 is connected to the direction control interface of the servo driver. The rotation direction of the motor 20 is controlled by outputting high and low level signals. A high level indicates forward rotation and a low level indicates reverse rotation. The feedback signal line of the encoder built into the motor 20 is connected to the feedback interface of the servo driver. The driver then connects the processed encoder signal to the communication module of the controller 2 through the communication interface. The controller 2 receives the encoder feedback signal, monitors the actual position and speed of the motor 20 in real time, compares it with the set value, realizes closed-loop control, and ensures the accuracy and stability of the operation of the motor 20.

[0033] When embossing stainless steel plates, the worker places the stainless steel plate on one of the lower mold cores 4. Then, the worker starts the motor 20 through the controller. The motor 20 drives the rotating shaft 21 to rotate, the rotating shaft 21 drives the turntable 24 to rotate, and the turntable 24 drives the two lower molds 3 and the lower mold cores 4 to rotate. The lower mold core 4 with the stainless steel plate is rotated to be directly below the upper mold core 6. After that, the controller stops the motor 20. At this time, the upper mold core 6 embosses the stainless steel plate on the lower mold core 4 below it. The worker removes the embossed stainless steel plate from the other lower mold core 4 and puts in the next stainless steel plate to be embossed. The worker repeats the above steps to perform multi-station embossing processing on the stainless steel plates.

[0034] Furthermore, a groove 22 is provided on the surface of the support plate 19, and a slider 23 is slidably engaged with the outer wall of the groove 22. The outer wall of the slider 23 is fixed to the bottom of the turntable 24.

[0035] In the specific implementation process, it is worth noting that when the turntable 24 rotates, the turntable 24 drives the slider 23 to rotate. The slider 23 slides in the groove 22 to guide and limit the turntable 24, preventing the turntable 24 from radially deviating during rotation.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
