Description

Technical Field

[0001] This invention relates to the field of stamping technology for servo motor parts, and in particular to an ultra-high-speed stamping device for T-shaped pieces of servo motors. Background Technology

[0002] Servo motors can control speed and achieve highly accurate rotational positioning. They convert voltage signals into torque and speed to drive the controlled object. The rotor speed of a servo motor is controlled by the input signal and can respond quickly, exhibiting excellent control precision. T-shaped pieces are one of the components of a servo motor. In the production process, to improve processing efficiency, high-speed stamping devices are required. However, current high-speed stamping devices typically use eccentric wheels for control. The operation of the eccentric wheel is mainly unilateral control, meaning that this stamping method can only form unidirectional T-shaped pieces on the material sheet, resulting in low material utilization and significant material waste. Furthermore, the stamping head cannot be quickly changed or adjusted, limiting its applicability. Moreover, the existing stamping device structure is not adjustable, leading to poor operability and high operating costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that the current high-speed stamping device is mainly controlled on one side. This stamping method can only form a unidirectional T-shaped piece on the material plate, resulting in low material utilization and serious material waste. At the same time, it is impossible to quickly replace and adjust the stamping head, resulting in limited applicability. Moreover, the structure of the existing stamping device cannot be adjusted, resulting in poor operability and high cost of use in the later stage.

[0004] The technical solution adopted by the present invention to solve its technical problem is: an ultra-high speed stamping device for servo motor T-shaped pieces, including a side feeding bracket for conveying stamping raw materials and a vertical main frame. Inside the vertical main frame, below the side feeding bracket, a first embedded bottom mold and a second embedded bottom mold are installed. Inside the vertical main frame, above the first embedded bottom mold and the second embedded bottom mold, an electrically controlled telescopic top mold is provided. Bottom stacking feeding components are provided on the inner bottom surface of the vertical main frame, directly below the first embedded bottom mold and the second embedded bottom mold.

[0005] The lateral conveying support includes a horizontal conveying support and a control conveying device installed at the loading end of the horizontal conveying support.

[0006] The electrically controlled telescopic top mold includes a centrally mounted drive gear movably assembled inside the vertical main frame, a first telescopic stamping die slidably assembled inside the vertical main frame, a second telescopic stamping die slidably assembled inside the vertical main frame, a first eccentric drive shaft connected between the centrally mounted drive gear and the first telescopic stamping die, a second eccentric drive shaft connected between the centrally mounted drive gear and the second telescopic stamping die, a drive gear meshing with the centrally mounted drive gear, and a side-mounted drive motor for controlling the drive gear.

[0007] The vertical main frame has a bottom lifting channel inside the lifting section of the first telescopic stamping die and the second telescopic stamping die. An electrically controlled telescopic side guide limit wall is provided on the inner side of the bottom lifting channel.

[0008] Both the first telescopic stamping die and the second telescopic stamping die consist of an upper mounting base with a transverse control shaft on one side of the top and a split-type side stamping head. The lower surface of the upper mounting base and the upper surface of the split-type side stamping head are provided with mutually cooperating side assembly grooves.

[0009] The controlled material conveying device includes a translational conveyor belt mounted on a horizontal conveying support and a lateral belt conveyor wheel assembly mounted on the drive shaft outside the side drive motor and on one side axle of the translational conveyor belt.

[0010] The bottom surface of the vertical main frame is located at the bottom stacking material conveying assembly end and has a bottom discharge port that communicates with the inside of the first embedded bottom mold and the second embedded bottom mold.

[0011] The bottom stacking feeding assembly includes a lateral tilting frame movably mounted on both sides of the bottom discharge port via a lateral assembly shaft, a bottom guide belt movably mounted inside the lateral tilting frame, and a lateral electrically controlled support rod mounted between the bottom discharge port and the lateral tilting frame.

[0012] The vertical main frame includes a bottom support fixedly installed at the bottom of the lateral feeding bracket, a top operating seat fixedly installed above the bottom support via the bottom support frame, and a top mounting seat bolted to the upper end of the top operating seat.

[0013] The central drive gear has lateral bosses with an integral structure that protrudes outward on both sides. The vertical main frame is internally fitted with lateral support wheels to improve the rotational stability and guidance of the lateral bosses.

[0014] The beneficial effects of this invention are: (1) The ultra-high speed stamping device for T-shaped pieces of servo motors of the present invention adopts a double stamping head design and a staggered layout design, which can perform staggered stamping on the material plate, greatly improving the utilization rate of the material plate and reducing waste; (2) By adopting the quick-release structure design of the first telescopic stamping die and the second telescopic stamping die, the stamping head can be quickly replaced as needed, which greatly enhances its applicability. (3) The vertical main frame adopts a detachable structure design, which facilitates later maintenance and replacement; (4) A bottom stacking conveyor assembly is provided on the bottom surface of the vertical main frame, directly below the first embedded bottom mold and the second embedded bottom mold. It can be flipped and stored when idle and flipped and unfolded when busy to separate, store and stack the T-shaped pieces, making it convenient to pick up and put down the material. (5) The central drive gear uses eccentric drive shafts on both sides to drive the telescopic stamping dies at the corresponding positions. By using reciprocating staggered stamping, the stroke wasted by the stamping head during reset is reduced, which greatly improves the stamping efficiency. (6) A single motor can be used to synchronously control the electric telescopic top mold and the material conveying device, resulting in better utilization of the power components.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Figure 1 , Figure 2 , Figure 3and Figure 4 The ultra-high-speed stamping device for servo motor T-shaped sheets shown includes a side feeding bracket 1 for conveying stamping raw materials and a vertical main frame 2. Inside the vertical main frame 2, below the side feeding bracket 1, are installed a first embedded bottom mold 3 and a second embedded bottom mold 4. Inside the vertical main frame 2, above the first embedded bottom mold 3 and the second embedded bottom mold 4, are electrically controlled telescopic top molds 5. Bottom stacking feeding components 6 are provided on the inner bottom surface of the vertical main frame 2, directly below the first embedded bottom mold 3 and the second embedded bottom mold 4.

[0023] To facilitate material conveying, the lateral conveying support 1 includes a horizontal conveying support 101 and a control conveying device 102 installed at the loading end of the horizontal conveying support 101.

[0024] To facilitate staggered lifting, the electrically controlled telescopic top mold 5 includes a central drive gear 51 movably mounted inside the vertical main frame 2, a first telescopic stamping mold 52 slidably mounted inside the vertical main frame 2, a second telescopic stamping mold 53 slidably mounted inside the vertical main frame 2, a first eccentric drive shaft 54 ​​connecting the central drive gear 51 and the first telescopic stamping mold 52, a second eccentric drive shaft 55 connecting the central drive gear 51 and the second telescopic stamping mold 53, a drive gear 56 meshing with the central drive gear 51, and a side drive motor 57 for controlling the drive gear 56.

[0025] The side-mounted drive motor 57 controls the rotation of the drive gear 56, which in turn drives the central drive gear 51 to rotate. The central drive gear 51 then rotates, causing the first eccentric drive shaft 54 ​​to raise the first telescopic stamping die 52 and the second eccentric drive shaft 55 to lower the second telescopic stamping die 53. The first and second eccentric drive shafts 54 and 55 are not diagonally positioned on either side of the central drive gear 51, but rather offset to one side. This arrangement is used to change the stamping gap between the first and second telescopic stamping dies 52 and 53. For example, after the first telescopic stamping die 52 stamps for the first time, the second telescopic stamping die 53 starts stamping after a one-second interval, and then the first telescopic stamping die 52 stamps again after a two-second interval. This allows the first telescopic stamping die 52 to be offset from the stamping opening of the second telescopic stamping die 53.

[0026] Working process: The material plate passes laterally through the vertical main frame 2 via the side conveying bracket 1. Then, the side drive motor 57 inside the vertical main frame 2 controls the drive gear 56 to rotate, thereby driving the central drive gear 51 to rotate. The central drive gear 51 starts to rotate, thereby driving the first eccentric drive shaft 54 ​​to control the first telescopic stamping die 52 to rise, and driving the second eccentric drive shaft 55 to control the second telescopic stamping die 53 to fall. Then, continuous and uninterrupted stamping operation is performed to form T-shaped plates with alternating positive and negative directions on the material plate. At the same time, the side drive motor 57 drives the material plate to move continuously through the linked conveying device 102.

[0027] In order to facilitate internal lifting and adjustment, a bottom lifting channel 7 is provided inside the vertical main frame 2 in the lifting section of the first telescopic stamping die 52 and the second telescopic stamping die 53. An electrically controlled telescopic side guide limit wall 8 is provided on the inner side of the bottom lifting channel 7.

[0028] The electrically controlled telescopic side-mounted guide limiting wall 8 consists of a lateral adjustment support rod fixed on the inner side of the bottom lifting channel 7 and a lateral limiting plate fixed on the lateral extension end of the lateral adjustment support rod.

[0029] To facilitate lateral assembly, both the first telescopic stamping die 52 and the second telescopic stamping die 53 consist of an upper mounting base 231 with a transverse control shaft on one side of the top and a split lateral stamping head 232. The lower surface of the upper mounting base 231 and the upper surface of the split lateral stamping head 232 are provided with mutually cooperating lateral assembly grooves 233.

[0030] Through the action of the electrically controlled telescopic side guide limiting wall 8, the first telescopic stamping die 52 or the second telescopic stamping die 53 can be squeezed and limited from the split end side, ensuring that the upper mounting base 231 and the split side stamping head 232 cannot be separated. In this way, the first telescopic stamping die 52 or the second telescopic stamping die 53, which is composed of the upper mounting base 231 and the split side stamping head 232, can be adjusted up and down along the bottom lifting channel 7.

[0031] The disassembly method can be to disassemble the vertical main frame 2 as a whole, and then separate the upper mounting base 231 and the split side punch head 232; or adjust the electrically controlled telescopic side guide limit wall 8, and then separate the split side punch head 232 laterally, and then separate and replace it from the lower opening of the bottom lifting channel 7.

[0032] To facilitate lateral synchronous conveying, the control conveying device 102 includes a translational conveyor belt 1021 mounted on a transverse conveyor support 101 and a lateral belt conveyor wheel set 1022 mounted on the drive shaft outside the lateral drive motor 57 and on one side axle of the translational conveyor belt 1021.

[0033] The side-mounted drive motor 57 drives the lateral belt conveyor wheel set 1022 to synchronously drive the translational conveyor belt 1021, thereby driving the material plate to move and be conveyed on the horizontal conveyor support 101.

[0034] To facilitate the material feeding operation, the bottom surface of the vertical main frame 2 is provided with a bottom feeding port 9 that communicates with the inside of the first embedded bottom mold 3 and the second embedded bottom mold 4 at the assembly end of the bottom stacking conveyor assembly 6.

[0035] To facilitate lateral tilting adjustment, the bottom stacking feeding assembly 6 includes a lateral tilting frame 11 movably mounted on both sides of the bottom discharge port 9 via a lateral assembly shaft, a bottom guide belt 12 movably mounted inside the lateral tilting frame 11, and a lateral electrically controlled support rod 13 mounted between the bottom discharge port 9 and the lateral tilting frame 11.

[0036] Both the bottom guide belt 12 and the lateral electrically controlled support rod 13 are existing technologies, and their angle is changed by extension and retraction. During idle periods, the lateral electrically controlled support rod 13 can be retracted to completely retract the lateral flipping frame 11 and the bottom guide belt 12 into the bottom discharge port 9; during busy periods, the lateral electrically controlled support rod 13 is extended to flip and unfold the lateral flipping frame 11 and the bottom guide belt 12 outwards, thus forming an outwardly unfolding conveyor belt mechanism. Its main function is to guide the outer storage box used for stacking T-shaped pieces into the bottom discharge port 9, then stack the fallen T-shaped pieces. After one stack is completed, it can be moved to one side, and a new storage box can be moved from the bottom guide belt 12 on the other side. This allows for uninterrupted stacking and storage without affecting loading, unloading, and replacement.

[0037] To facilitate loading and unloading, the vertical main frame 2 includes a bottom support 21 fixedly installed at the bottom of the side conveying bracket 1, a top operating seat 23 fixedly installed above the bottom support 21 by a bottom support frame 22, and a top mounting seat 24 bolted to the upper end of the top operating seat 23.

[0038] By disassembling the top mounting base 24, the entire electrically controlled telescopic top mold 5 can be disassembled and separated, facilitating later maintenance and replacement.

[0039] In order to improve the guidance and stability of the central drive gear 51 and reduce its internal friction during rotation, the central drive gear 51 has lateral bosses 58 with an outward protrusion on both sides. The vertical main frame 2 is equipped with lateral support wheels 59 to improve the rotational stability and guidance of the lateral bosses 58.

[0040] The lateral support wheels 59 support and limit the lateral protrusions 58 from the upper and lower ends on both sides respectively.

[0041] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
