Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a vertical flipping stamping mechanism. Background Technology

[0002] The production of pressed glassware typically involves manual handling, using clamps to transfer products from molds onto a conveyor belt. In assembly line operations, manual operation is employed, with machine-produced products being manually clamped onto the conveyor belt for the next process. To address this, a vacuum flipping device for pressed glassware (patent number CN2024202502800) has been developed. Its structure mainly includes a base plate, a telescopic cylinder, a first optical axis, a first support plate, a sliding shaft seat, a manual adjustment mechanism, a second support plate, a second optical axis, a third support plate, and a vacuum rotation mechanism. Specifically, the telescopic cylinder is fixedly installed on the upper surface of the base plate; the lower end of the first optical axis is slidably installed in a circular hole inside the telescopic cylinder, and the upper end of the first optical axis is fixedly connected to the outermost circular hole of the second support plate; the lower surface of the first support plate is fixedly connected to the upper surface of the telescopic cylinder; the sliding shaft seat is fixedly installed in a circular hole at the middle position of the second support plate; and the second optical axis is slidably connected to the sliding shaft seat. To achieve the function of vacuum flipping of glassware, the device drives the rack inside the reverse control box by extending and retracting the reverse cylinder. The rack inside the reverse control box pushes the gear inside the reverse control box, thereby realizing the rotation of the reverse rod, and finally achieving the vacuum flipping of the glassware.

[0003] However, the above-mentioned technical solutions have many shortcomings. For example, the manual adjustment mechanism adjusts the position of the second support plate by using a hand crank, a turbine assembly, and a worm gear. The operation process is cumbersome and requires continuous manual operation of the hand crank. This is not only inefficient, but also makes it difficult to guarantee the accuracy and stability of the adjustment by manual operation. It is easy to cause adjustment errors due to human factors, which will affect the subsequent flipping and processing quality of the glassware. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a flip-over stamping mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flipping stamping mechanism, comprising: a support frame, a flipping component rotatably disposed within the support frame, a motor driving the flipping component to rotate, a pressing mold disposed on the flipping component, and a pressing component disposed on the support frame and coinciding with the axis of the pressing mold; and a lifting and demolding component disposed at the bottom end of the pressing mold, wherein the lifting and demolding component rotates synchronously with the pressing mold and the flipping component.

[0006] As a preferred embodiment of this application, the flipping assembly includes: two columns disposed on the support frame, with a gap between the columns; a flipping support rod rotatably disposed between the two columns; one end of the flipping support rod is connected to the power output end of the motor and the motor is fixed on one column; and the other end of the flipping support rod is connected to the column through a rotating bearing.

[0007] Furthermore, the flipping support rod is provided with a mold base that is detachably connected to the pressing mold.

[0008] As a preferred embodiment of this application, the pressing assembly includes: a fixing member disposed between the support frames, a punch rod disposed within the fixing member, and a lifting drive provided on the top of the punch rod.

[0009] As a preferred embodiment of this application, a movable limiting rod is provided within the fixing member with the punch rod as the central axis.

[0010] As a preferred embodiment of this application, a baffle is provided at the bottom of the punch to abut and position against the pressing die.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: Synchronous rotation design: The lifting and demolding assembly rotates synchronously with the pressing die and the flipping assembly. This design greatly improves the continuity and stability of the entire stamping process. During the rotation of the pressing die driven by the flipping assembly, the lifting and demolding assembly maintains a constant relative position with the pressing die, ensuring that the workpiece inside the die is not accidentally disturbed or damaged during the flipping process. This guarantees the accuracy of the workpiece's position during transitions between workstations, providing a reliable guarantee for subsequent stamping and demolding operations. High-efficiency stamping: The motor drives the flipping assembly to rotate, thereby enabling the pressing die to reach the designated position for stamping operations. This structure allows the stamping process to be precisely controlled by the motor, enabling adjustments to stamping speed, force, and other parameters according to different workpiece requirements, ensuring the stability and consistency of stamping quality. Simultaneously, the flipping assembly enables multi-station stamping, improving production efficiency. For example, different stamping processes can be completed sequentially within a complete flipping cycle, significantly shortening the production cycle of a single workpiece.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-3 As shown, a flip-over stamping mechanism includes: a support frame 1, a flipping component 2 rotatably disposed within the support frame 1, a motor 3 driving the flipping component 2 to rotate, a pressing die 4 disposed on the flipping component 2, and a pressing component 5 disposed on the support frame 1 and coinciding with the axis of the pressing die 4; and a lifting and demolding component disposed at the bottom end of the pressing die 4, which rotates synchronously with the pressing die 4 and the flipping component 2. In this embodiment, the support frame 1 provides a stable support structure for the entire mechanism. After the motor 3 starts, its power output end drives the flipping component 2 to rotate. Since the pressing die 4 is disposed on the flipping component 2, it rotates together with the flipping component 2. When the pressing die 4 rotates to a position coinciding with the axis of the pressing component 5, the pressing component 5 performs a stamping operation on the workpiece inside the pressing die 4. At the same time, the lifting and demolding component is disposed at the bottom end of the pressing die 4 and rotates synchronously with the pressing die 4 and the flipping component 2. After stamping is completed, the lifting and demolding component can cooperate with other actions to push the workpiece out of the pressing die 4, completing the demolding. Among them, motor 3: adopts servo motor 3, such as Panasonic MSMD023P1U (the specific model needs to be selected according to the power and torque requirements).

[0019] Pressing mold 4: Customized according to the shape and size of the workpiece, such as mold number M123456.

[0020] Lifting and demolding assembly 6: Uses a pneumatic lifting device, such as SMC's MGPM series cylinders.

[0021] It achieves automation and continuity of the stamping process. By rotating the flipping component 2, multi-station operation can be realized, improving production efficiency.

[0022] The lifting demolding component rotates synchronously with the pressing mold 4, ensuring a smooth connection between the demolding action and the stamping process, avoiding damage to the workpiece during demolding, and improving product quality.

[0023] The overall structure is compact, and the components work together, which reduces the equipment's footprint and lowers production costs.

[0024] The flipping assembly 2 includes: two uprights 21 disposed on the support frame 1, with a gap between the uprights 21; a flipping support rod 22 rotatably disposed between the two uprights 21; one end of the flipping support rod 22 is connected to the power output end of the motor 3, and the motor 3 is fixed to one upright 21; the other end of the flipping support rod 22 is connected to the upright 21 through a rotating bearing 23. The principle is that the two uprights 21 are disposed on the support frame 1 with a gap, providing installation space for the flipping support rod 22. The flipping support rod 22 is rotatably disposed between the two uprights 21, with one end connected to the power output end of the motor 3, the motor 3 fixed to one upright 21, and the other end connected to the upright 21 through the rotating bearing 23. When the motor 3 starts, power is transmitted to the flipping support rod 22 through the power output end, causing it to rotate around the axis between the uprights 21. The advantages are simple structure, easy installation and maintenance, and reduced manufacturing and maintenance costs. The uprights 21 are made of high-strength steel, such as Q235.

[0025] Tilting support rod 22: Made of high-strength alloy steel, such as No. 45 steel.

[0026] Rotating bearing 23: Uses deep groove ball bearings, such as NSK's 6205 model.

[0027] The use of rotating bearing 23 reduces the friction when the tilting support rod 22 rotates, improves the smoothness and accuracy of rotation, and extends the service life of the equipment.

[0028] The motor 3 is directly connected to the tilting support rod 22, which has high power transmission efficiency and can quickly respond to control signals to achieve precise control of tilting speed and angle.

[0029] The flip support rod 22 is equipped with a mold base 24 that is detachably connected to the pressing mold 4. In this embodiment, the mold base 24 is set on the flip support rod 22, and the mold base 24 and the pressing mold 4 are detachably connected, such as by bolts or snap-fit ​​connections. When it is necessary to replace the pressing mold 4 with a different specification or type, simply remove the original mold from the mold base 24 and install the new mold on the mold base 24. The mold base 24 is made of high-strength aluminum alloy, such as 6061-T6.

[0030] It improves the versatility and flexibility of the equipment, enabling it to adapt to the production needs of different products and reducing the cost of remanufacturing or purchasing new equipment when changing products.

[0031] The detachable connection method is convenient and quick, shortens mold changeover time, and improves production efficiency.

[0032] This facilitates the repair and maintenance of the pressing mold 4. When the mold malfunctions, it can be disassembled and repaired separately without affecting the normal operation of other components.

[0033] The pressing assembly 5 includes: a fixing member 51 disposed between the support frames 1; a punch 52 disposed within the fixing member 51; and a lifting drive 53 disposed on the top of the punch 52. Its function is to provide a mounting base for the punch 52 by fixing the fixing member 51 between the support frames 1. The punch 52 is disposed within the fixing member 51, and the lifting drive 53 is disposed on the top of the punch 52. When the lifting drive 53 operates, it drives the punch 52 to move up and down within the fixing member 51. When the punch 52 moves downward, it applies pressure to the workpiece within the pressing die 4, completing the pressing operation. The lifting drive 53 is a hydraulic cylinder or a pneumatic cylinder, such as an SMC MGPM series pneumatic cylinder.

[0034] Punch bar 52: Made of high-strength alloy steel, such as No. 45 steel.

[0035] The advantages are structural stability, with the punch 52 moving within the fixed part 51, ensuring the stability and precision of the stamping process and improving product quality.

[0036] The lifting drive 53 can adjust the descent speed and pressure of the punch 52 according to different workpiece requirements to meet diverse production needs.

[0037] The fixing component 51 guides the punch 52, reducing the offset of the punch 52 during movement and extending the service life of the punch 52.

[0038] A movable limiting rod 54 is provided within the fixing member 51 with the punch rod 52 as the central axis. When the punch rod 52 moves up and down within the fixing member 51, the movable limiting rod 54 restricts the movement range of the punch rod 52, preventing the punch rod 52 from exceeding the safe movement range and avoiding collisions with the fixing member 51 or other components. This improves the safety of the equipment and prevents equipment damage and personal injury accidents caused by excessive movement of the punch rod 52.

[0039] This ensures the stability and consistency of the stamping process, guaranteeing that each stamping operation is carried out within the predetermined range, thereby improving product quality.

[0040] This reduces equipment maintenance costs and downtime, and extends the equipment's lifespan.

[0041] A baffle 55 is positioned at the bottom of the punch 52, abutting against the pressing die 4. When the punch 52 moves downwards for stamping, the baffle 55 first contacts the pressing die 4, achieving precise positioning between the punch 52 and the pressing die 4. Through the positioning function of the baffle 55, it is ensured that the punch 52 can accurately apply pressure to the workpiece within the pressing die 4, guaranteeing stamping quality.

[0042] The advantages are improved stamping accuracy and consistency, avoiding stamping defects caused by inaccurate positioning of punch 52 and pressing die 4, and improving product quality.

[0043] This reduced the scrap rate caused by inaccurate positioning and lowered production costs.

[0044] The baffle 55 has a simple structure, is easy to process and install, has little impact on the overall structure of the equipment, and will not increase manufacturing costs excessively.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
