Description

Technical Field

[0001] This utility model relates to the technical field of stamping device structure, specifically a servo feeding and pressing mechanism for a stamping device. Background Technology

[0002] In stamping equipment, such as punch presses, stamping processes are widely used. A large part of stamping is the drawing process, where a drawing punch presses and draws specific locations on the sheet metal. To ensure drawing accuracy, the sheet metal around the drawing location needs to be pressed and fixed during the drawing process. Existing blank holder mechanisms drive all blank holder rods at the same time, making it impossible to adjust the blank holder angle and time according to the needs of different stations. Moreover, it is difficult to maintain a constant pressure on a single blank holder rod, affecting the accuracy of the drawing process. Furthermore, existing feeding mechanisms have complex structures and are prone to interference with the blank holder mechanism. Utility Model Content

[0003] This invention provides a servo feeding and pressing mechanism for a stamping device, which can solve the problems of existing pressing mechanisms being unable to independently control the angle and time, and being unable to guarantee the quality of the stretching process.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a servo feeding and pressing mechanism for a stamping device, comprising a body, a worktable arranged on the lower inner side of the body, a mold arranged on the upper side of the worktable, a horizontally movable feeding platform arranged on the upper side of the mold, a cam mounted on the upper end of the feeding platform, and limit bosses arranged on both sides of the upper end of the feeding platform at the cam. The cam is driven to rotate by a servo motor on the side of the body, thereby driving the feeding platform to move back and forth. Several pressing components matching the stamping stations on the mold are installed on one side of the worktable. The pressing component includes a bracket and a rotating shaft arranged on the upper side of the bracket. At least one pressing rod extending upwards towards the mold is connected to the rotating shaft. One end of the pressing rod is connected to a vertical power component inside the bracket. The rotation of the cam can realize the stable back and forth movement of the feeding platform. When the feeding platform is fed forward, it can cooperate with the pressing component to realize the corresponding pressing of the sheet metal at each station. The angle and time can be adjusted individually.

[0005] Preferably, a transverse through groove is provided on the feeding platform below the cam, and the servo motor is installed below the feeding platform. Its main shaft passes through the transverse through groove and is connected to the cam. By setting the servo motor, the cam can be driven to rotate stably and cooperate precisely with the pressing assembly.

[0006] Preferably, the upper side of the cam is vertically connected to a guide rod that is coaxially arranged with the main shaft of the servo motor. The upper end of the guide rod is connected to the side of the machine body, which can limit the rotation of the cam and prevent left and right deviation.

[0007] Preferably, the vertical power component is a pneumatic cylinder or an electric cylinder. The rotation angle and pressing time of the pressing rod can be flexibly adjusted by the pneumatic cylinder or electric cylinder, and the pneumatic cylinder or electric cylinder can also facilitate pressure holding.

[0008] Preferably, the front end of the pressure bar is provided with a clearance groove to avoid the stretching position on the work station.

[0009] Preferably, the end of the pressure bar is connected to a flipping block, which is mounted on a rotating shaft. The end of the flipping block is connected to a vertical power component, which facilitates the replacement and adjustment of the pressure bar.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] With a simple structure and low cost, the feeding platform can move back and forth stably by rotating the cam. When the feeding platform is feeding forward, it can work with the pressing component to press the corresponding plates at each station. The angle and time can be adjusted individually, and the stretching process at each station can be flexibly adjusted. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-5 As shown, this utility model provides the following technical solution to solve the problems of existing pressing mechanisms being unable to independently control angle and time, and unable to guarantee the quality of the stretching process: A servo-feed pressing mechanism for a stamping device, comprising a body 1, a worktable 2 provided on the lower inner side of the body 1, a mold 4 provided on the upper side of the worktable 2, a horizontally movable feeding platform 7 provided on the upper side of the mold 4, a cam 5 mounted on the upper end of the feeding platform 7, and limit bosses 6 provided on both sides of the upper end of the feeding platform 7 located on the cam 5. The cam 5 is driven to rotate by a servo motor 8 on the side of the body 1, thereby... The feeding platform 7 moves back and forth. Several pressing components 3 that match the stamping stations on the mold 4 are installed on one side of the workbench 2. The pressing component 3 includes a bracket 35 and a rotating shaft 34 set on the upper side of the bracket 35. At least one pressing rod 33 extending upwards from the mold 4 is connected to the rotating shaft 34. One end of the pressing rod 33 is connected to the vertical power component inside the bracket 35. The feeding platform 7 can move back and forth stably by rotating the cam 5. When the feeding platform 7 feeds forward, it can cooperate with the pressing component 3 to press the corresponding sheet metal at each station. The angle and time can be adjusted individually.

[0021] Specifically, the feeding platform 7 is equipped with multiple robotic arms (not shown in the figure). These robotic arms can grip the sheet material and continuously transport it forward. The cam 5 and the limiting boss 6 work together to move the feeding platform 7 back and forth. The pressing assembly 3 can be equipped with multiple pressing rods 33, which can be configured as needed. The vertical power component can be a pneumatic cylinder 36 or an electric cylinder 31. The rotation angle and pressing time of the pressing rods 33 can be flexibly adjusted by the pneumatic cylinder 36 or the electric cylinder 31. The pneumatic cylinder 36 or the electric cylinder 31 can also be used for pressure holding, and can be selected as needed.

[0022] In this embodiment, the front end of the pressure bar 33 is provided with a clearance groove to avoid the stretching position on the work station.

[0023] In this embodiment, a transverse through groove is provided on the feeding platform 7 on the lower side of the cam 5. The servo motor 8 is installed below the feeding platform 7, and its main shaft passes through the transverse through groove and is connected to the cam 5. By setting the servo motor 8, the cam 5 can be driven to rotate stably and cooperate precisely with the pressing assembly 3.

[0024] like Figure 1-3As shown, the upper side of the cam 5 is vertically connected to a guide rod 9 that is coaxially arranged with the main shaft of the servo motor 8. The upper end of the guide rod 9 is connected to the side of the machine body 1, which can limit the rotation of the cam 5 and prevent left and right deflection.

[0025] To facilitate the replacement of the pressure bar 33, the end of the pressure bar 33 is connected to a flip block 32, which is mounted on a rotating shaft 34. The end of the flip block 32 is connected to a vertical power component, which makes it easy to replace and adjust the pressure bar 33.

[0026] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0027] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
