Description

Technical Field

[0001] This invention belongs to the technical field of thermos cup processing equipment, and particularly relates to a thermos cup shaping press. Background Technology

[0002] Chinese utility model patent with publication number "CN223276960U" discloses a robotic arm servo shaping machine. In its upper drive mechanism, the motor is fixed by a special mounting base. To accommodate the transmission rod passing through and connecting to the upper template below, an opening corresponding to the through slot needs to be opened at the bottom of the mounting base; at the same time, a slider is directly fixed to the inner side of the mounting base to guide the transmission rod. This structural design, which highly integrates the installation and guiding functions into a complex component, results in high difficulty in processing the mounting base, numerous steps, and high manufacturing costs.

[0003] Furthermore, in existing technologies, the upper template is typically connected to the transmission rod and guide limit rod via multiple separate connecting seats. These connecting seats consist of a central seat for connecting the transmission rod and corner seats on either side for fixing the guide limit rod. This separate structure not only complicates the assembly process but also increases the number of parts, further raising the overall processing cost and assembly difficulty of the workpiece. Simultaneously, in existing forming presses, the slider and guide rail experience constant sliding friction, requiring periodic manual lubrication. Manual lubrication is not only inconvenient but also prone to problems such as untimely lubrication and uneven lubrication, affecting the stability and lifespan of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a thermos cup shaping press to solve the technical problems of existing thermos cup shaping presses, such as the complex processing and high cost caused by the motor mounting base integrating installation and guiding functions, the large number of parts and complicated assembly caused by the separate connecting seats of the upper template, transmission rod and limit rod, and the inconvenient maintenance caused by the need for regular manual lubrication of the sliding friction parts between the slider and the guide rail.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a thermos cup shaping press, comprising a base frame, a drive frame mounted on the base frame, and a stamping mechanism for shaping the workpiece on the drive frame.

A sliding guide assembly is provided in the upper drive assembly for guiding the linear movement of the transmission rod. The sliding guide assembly integrates a lubrication supply unit.

[0006] Preferably, the upper drive assembly includes a mounting plate fixedly installed on the top of the drive frame and an upper motor assembly for transmission connection with the transmission rod. The upper motor assembly can drive the transmission rod to move up and down, and further drive the upper template to move synchronously through the connecting seat.

[0007] Preferably, the mounting plate has a through slot for the transmission rod to pass through, and the connecting seat has a mounting slot corresponding to the through slot. The transmission rod passes through the through slot and extends to the upper surface of the mounting plate, and is connected to the upper motor assembly for transmission.

[0008] Preferably, the sliding guide assembly includes a guide rail and a slider. The guide rail is mounted on one side of the transmission rod. The mounting plate is fixed with a mounting base for mounting the upper motor assembly and a sliding seat that slides with the guide rail. The slider and the sliding seat are fixedly connected. The upper motor assembly is a servo motor assembly, which is fixedly mounted on one side of the mounting base by bolts. The drive end of the upper motor assembly passes through a through hole opened on the mounting base and extends to the outside of the mounting base. The transmission rod is a rack, and the drive end of the upper motor assembly is fixedly connected to a transmission gear that meshes with the transmission rod.

[0009] Preferably, the connecting seat has a fixed slot, and a feeding cylinder is provided in the fixed slot. The feeding cylinder is fixedly installed on the upper template. The pushing end of the feeding cylinder passes through the through hole opened on the upper template and extends downward, and a feeding head is fixedly connected to it.

[0010] Preferably, the lubrication replenishment unit includes a liquid storage tank installed above the sliding seat and a liquid guiding part located on one side of the liquid storage tank. There is a flow channel between the liquid storage tank and the liquid guiding part, and a valve is provided at the connection between the two of the flow channel. The liquid guiding part is located above the slider, and the outlet of the liquid guiding part is arranged corresponding to the sliding contact surface between the slider and the guide rail.

[0011] Preferably, locking cylinders are fixedly installed on both sides of the mounting plate, the pushing ends of the two locking cylinders are arranged opposite each other, and a locking pin is fixedly installed on each pushing end. Locking blocks are fixedly installed on both sides of the lower surface of the mounting plate. A transverse through groove is opened on the locking block for the locking pin to pass through. A longitudinal through groove is also opened on the locking block. The locking block is sleeved on the outside of the limiting rod. A plurality of limiting holes are opened along its longitudinal direction to lock with the locking pin.

[0012] Preferably, the lower shaping part includes a lower template movably mounted on the drive frame, a lifting plate connected below the lower template, and a lower drive assembly for driving the lifting plate to move up and down and causing the lower template to move synchronously. The lower drive assembly includes a lower motor assembly and a transmission screw. The lower motor assembly is connected to the transmission screw via a coupling. A screw drive block is connected to the transmission screw, and the screw drive block is fixedly connected to the lifting plate.

[0013] Preferably, it further includes a connecting plate, the lower motor assembly is installed below the connecting plate, a plurality of guide rods are provided between the connecting plate and the base frame, and the lifting plate is slidably connected to the guide rods.

[0014] Preferably, the base frame is provided with a rear cabinet, and the top of the rear cabinet is provided with a cover for accommodating the upper shaping part. The base frame, the rear cabinet, and the cover are arranged together to form a body with an operating opening. A cable chain is provided inside the rear cabinet. The cable chain is fixedly connected to the upper template through a connector. A guide opening is provided on one side of the rear cabinet opposite to the operating opening. The connector of the cable chain can move along the extension direction of the guide opening. Dust covers are provided on the upper and lower sides of the connector. The dust covers are used to simultaneously block the guide opening during the movement of the upper template.

[0015] By employing the above technical solution, this invention, compared with existing technologies, has the following beneficial effects: By separately fixing the motor mounting base and the sliding seat to the mounting plate, it changes the design of existing technologies that integrates installation and guiding functions into the same complex component. This modular design simplifies the shape and function of the mounting base, allowing it to only undertake the task of fixing the motor, while separating the guiding function to an independent sliding seat. Furthermore, it eliminates the need for additional openings on the mounting base, thereby reducing the processing difficulty and manufacturing cost of individual parts, and making the assembly process more flexible and convenient. Thus, it solves the technical problem of complex processing and high costs caused by the integration of installation and guiding functions in the motor mounting base of existing thermos cup shaping presses.

[0016] By incorporating an integrated connecting seat on the upper template, this design integrates a mounting slot for connecting the transmission rod, a fixing slot for mounting the feeding cylinder, and a connecting structure for fixing the limiting rod. This integrated design replaces the existing split structure consisting of a middle seat and two side corner seats, reducing the number of parts, simplifying the assembly process, improving the structural stability and assembly efficiency of the upper template assembly, and further reducing manufacturing costs. This solves the technical problem of numerous parts and cumbersome assembly caused by the use of separate connecting seats for the upper template, transmission rod, and limiting rod in existing technologies.

[0017] Meanwhile, by integrating a lubrication replenishment unit into the sliding guide assembly, more convenient automatic lubrication replenishment of the sliding guide assembly can be achieved. Specifically, the lubrication replenishment unit includes a reservoir, a guide section, and a valve. The valve can be opened periodically or as needed. When the valve is opened, the lubricant in the reservoir flows into the guide section through the flow channel, and then automatically drips from the outlet through the guide section to cover the sliding contact surface between the slider and the guide rail, thereby achieving automatic lubrication. This avoids the tedious operation and untimely or uneven problems of manual lubrication, improves the reliability of equipment operation, and solves the technical problem of the existing thermos cup shaping press requiring periodic manual lubrication of the sliding friction parts between the slider and the guide rail, which is inconvenient to maintain.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] like Figure 1-11The image shows a thermos cup shaping press, comprising a base frame 1, a drive frame 2 mounted on the base frame 1, and a stamping mechanism mounted on the drive frame 2. The drive frame 2 is composed of multiple columns extending vertically upwards to guide the stamping mechanism. The stamping mechanism includes an upper shaping section 3 and a lower shaping section 4, arranged opposite each other, for stamping and shaping the thermos cup body. The upper shaping section 3 includes an upper template 301 and an upper drive mechanism for driving the upper template 301 to reciprocate linearly along the vertical direction of the drive frame 2. The upper template 301 is a high-strength flat plate, and a mold can be mounted on its lower surface. A connecting seat 302 is fixedly provided on the upper surface of the upper template 301. The connecting seat 302 is an integral component, and a vertically extending limiting rod 303 is fixed on each of the left and right sides of the connecting seat 302, i.e., at both ends along the horizontal direction. The two limiting rods 303 are parallel and symmetrically arranged. Between the limiting rods 303 on both sides, a vertically arranged transmission rod 304 is fixed on the connecting seat 302. The lower end of the transmission rod 304 is fixedly connected to the connecting seat 302 by threads or pins, and the upper end extends upward. The upper drive assembly is provided with a sliding guide assembly for guiding the linear movement of the transmission rod 304. This sliding guide assembly integrates a lubrication supply unit 13 to achieve automatic lubrication of the sliding contact surface.

[0024] like Figure 2-6 As shown, the upper drive assembly includes a mounting plate 305 fixedly mounted on the top of the drive frame 2 and an upper motor assembly 306 for transmission connection with the transmission rod 304. The mounting plate 305 is a horizontally arranged metal plate, firmly fixed to the top of the drive frame 2 by bolts or welding, serving as a support platform for the upper drive assembly. The upper motor assembly 306 can drive the transmission rod 304 to move up and down, thereby driving the upper template 301 to move synchronously through the connecting seat 302. Specifically, the output shaft of the upper motor assembly 306 converts the rotational motion into the linear reciprocating motion of the transmission rod 304 through a transmission mechanism.

[0025] like Figure 8 As shown: A through slot 201 extending along the thickness direction is provided on the mounting plate 305. The shape of the through slot 201 matches the cross-section of the transmission rod 304, allowing the transmission rod 304 to pass through. Figure 7 As shown, the connecting seat 302 has a mounting groove 307 that corresponds vertically to and is coaxially arranged with the through groove 201. The mounting groove 307 is used to accommodate and fix the lower end of the transmission rod 304. The transmission rod 304 passes through the through groove 201 on the mounting plate 305 and the mounting groove 307 on the connecting seat 302 from top to bottom. Its lower end is locked in the mounting groove 307, while its upper end extends above the upper surface of the mounting plate 305 and forms a transmission connection with the upper motor assembly 306. In this way, when the transmission rod 304 moves up and down, it maintains a small gap with the through groove 201 on the mounting plate 305, and the through groove 201 itself plays a preliminary circumferential limiting role for the transmission rod 304.

[0026] like Figure 8-11 As shown: The sliding guide assembly includes a guide rail 5 and a slider 14. The guide rail 5 is a linear guide rail, fixedly installed vertically on the side of the transmission rod 304 facing away from the tooth surface, and can be fixed to the side of the transmission rod 304 by screws or welding. An independent mounting seat 6 and an independent sliding seat 7 are fixedly provided on the upper surface of the mounting plate 305. The mounting seat 6 is used to fix the upper motor assembly 306, and the sliding seat 7 is used for sliding engagement with the guide rail 5. Specifically, the slider 14 is fixedly connected to the sliding seat 7 by bolts. The inner side of the slider 14 has a sliding surface that matches the guide rail 5, allowing the slider 14 to slide linearly along the guide rail 5 with low friction. The mounting seat 6 and the sliding seat 7 are separate from each other and do not interfere with each other; both are fixed to the mounting plate 305 by bolts.

[0027] By separating the motor mounting base 6 and the sliding base 7, the design changes the existing technology that integrates mounting and guiding functions into a single complex component. This modular structure greatly simplifies the shape of the mounting base 6, eliminating the need for complex guide grooves or slider mounting surfaces, thus reducing processing difficulty and manufacturing costs. Simultaneously, the sliding base 7 can independently optimize guiding accuracy, offers greater assembly flexibility, and can be replaced separately during maintenance, improving the equipment's economy and maintainability.

[0028] like Figure 6 As shown: The upper motor assembly 306 is a servo motor group, which is fixedly mounted on one side of the mounting base 6 by bolts. A through hole is provided on the mounting base 6, through which the drive end of the upper motor assembly 306 passes and extends to the outside of the mounting base 6. The transmission rod 304 is a rack with continuous teeth machined on its drive-facing side. A transmission gear 308 is fixedly connected to the drive end of the upper motor assembly 306, and this transmission gear 308 meshes with the teeth on the transmission rod 304. When the upper motor assembly 306 is started, the transmission gear 308 rotates, converting the rotational motion into linear motion of the transmission rod 304 through the rack and pinion pair. A guide rail 5 is fixedly provided on the side of the transmission rod 304 away from the teeth, and the guide rail 5 slides with the slider 14 fixed on the sliding seat 7, thereby constraining the direction of movement of the transmission rod 304.

[0029] like Figure 7 As shown: A fixing slot 309 is provided on the connecting seat 302. The fixing slot 309 is a C-shaped slot, which is used to house the ejector cylinder 8. The cylinder body of the ejector cylinder 8 is fixedly installed on the upper surface of the upper template 301 by screws or clamps and is located in the C-shaped slot. Its pushing end extends vertically downward, passes through the corresponding through hole on the upper template 301, and is fixedly connected to an ejector head 801 at its end. The ejector head 801 is cylindrical in shape and is used to eject the workpiece downward after stamping.

[0030] like Figure 9-11 As shown: The lubrication supply unit 13 includes a reservoir 1301 mounted above the sliding seat 7 and a guide section 1302 located on one side of the reservoir 1301. The reservoir 1301 is a sealed container storing lubricating oil or grease, and its top may have a filling port. The reservoir 1301 and the guide section 1302 are connected by a flow channel with an internal drilled hole or an external hose, and a valve is provided at the connection of the flow channel. This valve is a solenoid valve or a manual regulating valve, used to control the flow of lubricating fluid. Specifically, during operation, the PLC controller electrically connected to the valve can periodically control the valve to open for a certain period of time. The guide section 1302 is located directly above the slider 14, and its lower end has a liquid outlet 1303, which is directly opposite the sliding contact surface between the slider 14 and the guide rail 5, i.e., the contact area between the raceway of the slider 14 and the guide rail 5. When the valve is opened, the lubricating fluid in the storage tank 1301 flows into the liquid guiding part 1302 through the flow channel under the action of gravity, and then slowly drips or seeps out from the liquid outlet 1303 onto the sliding contact surface to achieve automatic lubrication.

[0031] By integrating the lubrication supply unit 13, automatic, quantitative, and timed lubrication of the sliding guide component is achieved, avoiding the tedious operation of manual periodic lubrication. It also solves the problem of accelerated wear of the guide rail caused by untimely and uneven manual lubrication, thereby improving the reliability of equipment operation and the service life of the guide components.

[0032] like Figure 4-6 As shown: On the left and right sides of the mounting plate 305, corresponding to the positions of the two limit rods 303, a locking cylinder 9 is fixedly installed. The pushing ends of the two locking cylinders 9 are horizontal and opposite to each other. A locking pin 10 is fixedly installed on each pushing end. The end of the locking pin 10 can be processed into a conical or round head for easy insertion.

[0033] On both sides of the lower surface of the mounting plate 305, a locking block 11 is fixedly installed. The locking block 11 is a metal block with two through slots: one is a transverse through slot, the axis of which coincides with the axis of the locking pin 10, for the locking pin 10 to pass through; the other is a longitudinal through slot, the axis of which is vertical, for fitting the limiting rod 303. The locking block 11 is fitted onto the outside of the limiting rod 303 through its longitudinal through slot, so that the limiting rod 303 can slide freely up and down within the longitudinal through slot, while the locking block 11 itself remains fixed.

[0034] Multiple limiting holes 12 are provided vertically on the limiting rod 303. The diameter of these limiting holes 12 matches the diameter of the locking pin 10, and the spacing between the holes can be set as needed. When it is necessary to lock the upper template 301, the locking cylinder 9 pushes the locking pin 10 through the transverse through groove of the locking block 11 and inserts it into the limiting hole 12 on the limiting rod 303 corresponding to the current height, thereby fixing the limiting rod 303 and the locking block 11 relative to each other, thus preventing the upper template 301 from moving up and down.

[0035] like Figure 3-5 As shown: The lower forming section 4 includes a lower template 401 movably mounted on the drive frame 2, a lifting plate 402 connected below the lower template 401, and a lower drive assembly for driving the lifting plate 402 to move up and down and synchronously move the lower template 401. The upper surface of the lower template 401 is used to mount the lower die, which cooperates with the upper template 301 to complete the stamping. The lower template 401 is fixedly connected to the lifting plate 402 by bolts or guide pillars.

[0036] The lower drive assembly includes a lower motor assembly 403 and a transmission screw 404. The lower motor assembly 403 is also a servo motor, and its output shaft is connected to the lower end of the transmission screw 404 via a coupling. A screw drive block 405 is connected to the transmission screw 404, and the screw drive block 405 is fixedly connected to the lower surface of the lifting plate 402. When the lower motor assembly 403 starts, the transmission screw 404 rotates, and the screw drive block 405 moves linearly along the screw axis, thereby driving the lifting plate 402 and the lower template 401 to rise and fall synchronously.

[0037] The lower template is raised and lowered by a servo motor driven by a lead screw and nut assembly. This allows for precise control of the lower template's displacement and speed. When working in conjunction with the upper template, it can achieve complex stamping curves and improve the forming quality.

[0038] like Figure 3-5 As shown, the lower shaping section 4 also includes a connecting plate 406, which is horizontally fixed to the lower part of the drive frame 2. The lower motor assembly 403 is installed below the connecting plate 406 to save space. Several guide rods 407 are provided between the connecting plate 406 and the base frame 1. The guide rods 407 are smooth metal round rods, arranged vertically and parallel to each other. Linear bearings or sliding sleeves are provided at corresponding positions on the lifting plate 402, which are slidably connected to the guide rods 407. In this way, when the lifting plate 402 moves up and down, the guide rods 407 provide precise guidance, preventing the lower template 401 from tilting or shaking. By setting independent guide rods 407, the movement accuracy of the lower template 401 is not affected by the bending or swaying of the drive screw, which improves the rigidity and guiding accuracy of the lower shaping section and ensures the alignment of the upper and lower molds.

[0039] like Figure 1-2As shown: A rear cabinet 101 is mounted on the base frame 1. The rear cabinet 101 is a sheet metal welded box structure, with a top cover 102 to accommodate the upper shaping part 3, especially the upper part of the transmission rod 304 and the motor assembly. The base frame 1, the rear cabinet 101, and the top cover 102 enclose each other to form a machine body with an operation port 103 located at the front of the equipment for workpiece entry and exit. A cable chain 104 is installed inside the rear cabinet 101, which houses the wires and pneumatic hoses connected to the upper motor assembly 306, the feeding cylinder 8, the locking cylinder 9, and other components. One end of the cable chain 104 is fixedly connected to the upper template 301 via a connector, i.e., a metal plate, while the other end is fixed to the inner wall of the rear cabinet 101. When the upper template 301 moves up and down, the cable chain 104 bends or extends accordingly, protecting the cables from stretching or wear.

[0040] like Figure 1-2 As shown, a guide opening, which is a vertical elongated slot, is provided on one side of the rear cabinet 101 opposite to the operation port 103. The connector of the cable chain 104 can move up and down along the extension direction of this guide opening. Dust covers 105 are provided on the upper and lower sides of the connector. The dust covers 105 are retractable foldable covers, one end of which is fixed to the connector, and the other end is fixed to the upper and lower edges of the guide opening respectively. When the upper template 301 moves upward, the connector moves upward, the upper dust cover 105 is compressed, and the lower dust cover 105 is stretched; the opposite is true when the upper template 301 moves downward. Regardless of the position of the connector, the dust cover 105 always blocks the rest of the guide opening, preventing external dust from entering the interior of the rear cabinet 101 from the guide opening. The combined design of the cable chain and dust covers ensures the free movement of the upper template while achieving safe cable guidance and good sealing of the machine body, improving the applicability and service life of the equipment in dusty environments, and also enhancing operational safety.

[0041] The working process of the thermos cup shaping press of this invention is as follows: In the initial state, the upper template 301 is in the standby position above the drive frame 2, the lower template 401 is at the lowest point, the locking pin 10 of the locking cylinder 9 is in the retracted state, and the feeding cylinder 8 is in the retracted state. Material loading and mold closing: The operator places the thermos cup blank to be shaped onto the lower mold of the lower template 401. The control system issues a start command, the upper motor assembly 306 starts, and the transmission gear 308 rotates clockwise or counterclockwise, driving the rack, which acts as the transmission rod 304, to move downwards along the vertical direction defined by the guide rail 5 and the slider 14. The transmission rod 304 drives the upper template 301 to descend synchronously through the connecting seat 302. During this process, the limiting rods 303 fixed on both sides of the upper template 301 slide synchronously within the positioning slots opened on the mounting plate 305, providing auxiliary guidance for the upper template 301 and preventing it from deflecting. Stamping and shaping: When the upper template 301 descends to the preset processing position, the upper motor assembly 306 stops. To improve safety and prevent the upper template from springing back during stamping, the locking cylinders 9 on both sides immediately activate, pushing the locking pin 10 through the transverse through slot of the locking block 11 and inserting it into the limiting hole 12 on the limiting rod 303 corresponding to the current height, reliably locking the upper template 301 at that height position. Then, the lower motor assembly 403 starts, driving the transmission screw 404 to rotate, and the screw drive block 405 moves upward, causing the lifting plate 402 to slide upward along the guide rod 407. Since the lifting plate 402 is fixedly connected to the lower template 401, the lower template 401 and the lower mold are lifted upward, causing the workpiece to gradually press against the upper mold. According to the process requirements, the lower motor assembly 403 can precisely control the rising speed and final pressure to complete the shaping of the thermos cup body. After the shaping and holding pressure time is completed, the lower motor assembly 403 reverses, causing the lower template 401 to descend and reset.

[0042] During equipment operation, the control system periodically opens the valve of the lubrication replenishment unit 13 after every 100 stamping cycles. The lubricating oil in the storage tank 1301 drips from the outlet 1303 through the flow channel and the liquid guide 1302 onto the sliding contact surface between the slider 14 and the guide rail 5, achieving automatic lubrication without manual intervention.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
