Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of lathe guide rail processing, specifically to a stamping device for forming a car window guide rail. Background Technology

[0002] In automotive window system manufacturing, window rails, as key structural components guiding the raising and lowering of windows, require stamping equipment to process metal sheets into specific cross-sectional shapes (such as U-shapes and grooves). The forming accuracy directly determines the smoothness and stability of window raising and lowering. With increasing demands for efficient production space utilization and process flexibility in automobile manufacturing, the shortcomings of traditional stamping equipment for window rail forming have become increasingly apparent: existing stamping equipment generally adopts a processing mode of progressive forming followed by final cutting and stripping, resulting in excessively long overall equipment stroke. This not only occupies a large amount of production space but also presents inconvenient adjustment drawbacks, severely restricting the flexibility of production layout and the adaptability to processing multiple specifications.

[0003] Traditional stamping equipment requires multiple sets of forming dies (such as pre-bending dies, shaping dies, and cutting dies) to be set up sequentially along the processing direction to achieve the step-by-step forming of window guide rails. The metal sheet must pass through each die to complete the shaping, and finally be removed by the cutting die. This step-by-step structure significantly increases the overall length of the equipment, requiring a large production area for equipment installation and operation. For companies with limited factory space, it is difficult to flexibly plan the production line layout. At the same time, the long equipment stroke also increases the difficulty of positioning during the sheet material transportation process, and the forming accuracy is prone to fluctuation due to transportation deviation.

[0004] Therefore, the development of a stamping device for forming car window guide rails that can optimize the forming process, shorten the equipment stroke, and is easy to adjust has become an urgent need to improve the utilization rate of production space and processing flexibility. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a stamping device for forming car window guide rails, which solves the technical problem that the stamping equipment in the prior art generally adopts a processing mode of step-by-step forming followed by final cutting and stripping, resulting in an excessively long overall stroke of the equipment, which not only occupies a large amount of production space, but also has the technical problem of inconvenient adjustment.

[0006] According to one aspect, at least one embodiment of this disclosure provides a stamping apparatus for forming a window guide rail, comprising: The machine body and a pair of uprights, each of which is fixed to both ends of the surface of the machine body; A pair of upper through cavities and a pair of lower through cavities and a stamping assembly, wherein the upper through cavities are opened on the side surfaces of the pair of uprights, the lower through cavities are opened on both sides of the body, and the stamping assembly is disposed in the body and the uprights; An infeed / outfeed assembly is disposed on the machine body; The stamping assembly includes a through-hole, which is formed on the surface of the machine body. Both the upper through-cavity and the lower through-cavity are connected to vertically moving seats via vertical linear drive. An upper stamping seat and a lower stamping seat are horizontally rotatably connected between a pair of opposing vertically moving seats.

[0007] As a further technical solution, several mold mounting slots are opened around the surface of both the upper and lower stamping seats, and several sets of telescopic positioning posts are arranged around the surface of the lower stamping seat, with springs fitted on each telescopic positioning post.

[0008] As a further technical solution, a number of positioning sleeves are arranged around the surface of the upper stamping seat. Each group of positioning sleeves and the telescopic positioning column are distributed at opposite corners. A circular groove is opened on the side surface of the vertical moving seat located on one side of the stand.

[0009] As a further technical solution, a limiting seat is provided at one end of the rotating shaft of the upper stamping seat, and a number of positioning grooves are opened around the outer surface of the limiting seat. A pressure-bearing support seat is connected to the machine body through a vertical linear drive, and the pressure-bearing support seat is attached to the bottom of the lower stamping seat.

[0010] As a further technical solution, a groove is provided on the side surface of the vertical moving seat, a telescopic cylinder is provided in the groove, a positioning block is provided at the output end of the telescopic cylinder, the positioning block is inserted into the positioning groove, and the positioning groove corresponds to the position and number of the mold mounting groove.

[0011] According to another aspect, in at least one embodiment of the present invention, the feeding and discharging assembly includes a moving trough, which is opened at both ends of the surface of the machine body.

[0012] As a further technical solution, the outer surfaces of the upper stamping seat and the lower stamping seat are polygonal in shape.

[0013] As a further technical solution, the surface of the conveying rollers is made of a frosted anti-slip structure, and the spacing between the conveying rollers is matched with the thickness of the raw material plate.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the stamping assembly solves the problems of long stroke and inconvenient adjustment in traditional devices through rotary switching and multi-directional positioning design. The upper and lower stamping seats can rotate and switch between multiple sets of dies, enabling continuous stamping of multiple processes without the need for step-by-step die setup, significantly shortening the overall equipment stroke and saving production space.

[0023] like Figures 1-4 As shown, a stamping apparatus for forming a window guide rail is illustrated in one embodiment of this disclosure, comprising: The machine body 1 and a pair of uprights 2 are fixed to both ends of the surface of the machine body 1; A pair of upper through cavities 3 and a pair of lower through cavities 4 and a stamping assembly 5, wherein the upper through cavities 3 are opened on the side surfaces of the pair of uprights 2, the lower through cavities 4 are opened on both sides inside the body 1, and the stamping assembly 5 is disposed in the body 1 and the uprights 2; Feeding / discharging assembly 6, which is disposed on the machine body 1; The stamping assembly 5 includes a through-hole 5-1, which is formed on the surface of the machine body 1. Vertical moving seats 5-2 are vertically linearly driven to both the upper through-cavity 3 and the lower through-cavity 4. An upper stamping seat 5-3 and a lower stamping seat 5-4 are horizontally rotatably connected between a pair of opposing vertical moving seats 5-2. Both the upper stamping seat 5-3 and the lower stamping seat 5-4 are electrically driven to rotate. Several mold mounting slots 5-5 are formed around the circumference of both the upper stamping seat 5-3 and the lower stamping seat 5-4. Several sets of telescopic positioning posts 5-6 are arranged around the circumference of the lower stamping seat 5-4, and springs 5-7 are fitted onto each telescopic positioning post 5-6. Several sets of positioning sleeves 5-8 are arranged around the circumference of the upper stamping seat 5-3. Each set of positioning sleeves 5-8 is connected to the telescopic positioning post. 5-6 are distributed at the four corners. A circular groove 5-9 is opened on the side surface of the vertical moving seat 5-2 located on one side of the stand 2. A limit seat 5-10 is provided at one end of the rotating shaft of the upper stamping seat 5-3. Several positioning grooves 5-11 are opened around the outer surface of the limit seat 5-10. A pressure-bearing support seat 5-12 is connected to the machine body 1 through a vertical linear drive. The pressure-bearing support seat 5-12 is attached to the bottom of the lower stamping seat 5-4. A groove 5-13 is opened on the side surface of the vertical moving seat 5-2. A telescopic cylinder 5-14 is provided in the groove 5-13. A positioning block 5-15 is provided at the output end of the telescopic cylinder 5-14. The positioning block 5-15 is inserted into the positioning groove 5-11. The positioning groove 5-11 corresponds to the mold mounting groove 5-5 in position and number.

[0024] In some examples, in order to achieve continuous rotation of the window guide rail, the mold is gradually stamped and cut off and then ejected downwards, avoiding the low efficiency caused by the need for multiple mold disassembly and assembly in traditional single-mold stamping, or the problem that the workpiece is difficult to eject after forming. A stamping component 5 is designed. This component includes a vertical moving seat 5-2 in the upper cavity 3 of the stand 2 and the lower cavity 4 inside the machine body 1. It can be synchronously raised and lowered vertically by vertical linear drive, which drives the relatively set upper stamping seat 5-3 and lower stamping seat 5-4 to move closer or further away, so as to provide pressure for stamping.

[0025] The upper stamping seat 5-3 and the lower stamping seat 5-4 are horizontally rotatably connected between the vertical moving seat 5-2 and are driven by electricity to rotate. Several mold mounting slots 5-5 around its surface can be used to install stamping dies for different processes (such as preliminary shaping, deep forming, cutting, etc.). When rotating, different dies can be switched to the stamping station in sequence to realize continuous stamping of multiple processes without stopping the machine to change dies, which greatly improves the forming efficiency.

[0026] Several sets of telescopic positioning pins 5-6 on the surface of the lower stamping seat 5-4 cooperate with the positioning sleeves 5-8 of the upper stamping seat 5-3. Each set is distributed at the four corners to form a four-corner positioning structure. During stamping, the telescopic positioning pins 5-6 are inserted into the positioning sleeves 5-8 under the action of the springs 5-7 to ensure that the molds of the upper and lower stamping seats 5-4 are accurately aligned and to avoid mold misalignment that leads to deviation in forming dimensions.

[0027] The elastic buffering effect of spring 5-7 can reduce the impact damage to the mold during stamping and extend the service life of the mold. In the circular groove 5-9 of the vertical moving seat 5-2 on one side of the stand 2, the positioning groove 5-11 on the outer surface of the limiting seat 5-10 at one end of the rotating shaft of the upper stamping seat 5-3 is opened, which cooperates with the positioning block 5-15 driven by the telescopic cylinder 5-14 in the groove 5-13 of the vertical moving seat 5-2. The positioning groove 5-11 corresponds to the mold mounting groove 5-5 in position and number. When a mold rotates to the stamping station, the telescopic cylinder 5-14 drives the positioning block 5-15 to insert into the corresponding positioning groove 5-11, restricting the rotation of the upper stamping seat 5-3, ensuring the stability of the mold position during stamping, and avoiding rotational deviation due to vibration.

[0028] Inside the machine body 1, a vertically linearly driven pressure-bearing support seat 5-12 is attached to the bottom of the lower stamping seat 5-4. During stamping, it supports the lower stamping seat 5-4 upwards, dispersing the stamping pressure and preventing the lower stamping seat 5-4 from deforming due to excessive force. After the cutting process, the pressure-bearing support seat 5-12 moves downwards, and at the same time, the lower stamping seat 5-4 can open or move aside at the corresponding mold position, allowing the formed workpiece to be ejected downwards, completing automatic unloading. During operation, the vertically moving seat 5-2 drives the mold to approach the stamping, and the rotating mold switches to complete multi-process forming. After cutting, the pressure-bearing support seat 5-12 moves downwards to eject the workpiece. Rotation switching enables continuous forming, multi-directional positioning ensures accuracy, pressure adjustment assists ejection, and all components work together to complete the continuous stamping and ejection of the window guide rail, meeting production requirements.

[0029] like Figures 1-4 As shown in the figure, the feeding and discharging assembly 6 in this embodiment includes a moving trough 6-1, which is opened at both ends of the surface of the machine body 1. A pair of conveying rollers 6-2 are provided on one side of the machine body 1, one of which is driven to rotate by electricity. A discharge port 6-3 is opened on one side of the machine body 1, and the bottom of the discharge port 6-3 is inclined.

[0030] In some examples, in order to achieve continuous feeding of sheet metal to cooperate with the stamping assembly 5 to complete the continuous stamping of the window guide rail, and to avoid the stamping rhythm disorder caused by manual intermittent feeding, or the finished product discharge being obstructed and affecting production efficiency, an infeed and discharge assembly 6 is designed. This assembly includes moving grooves 6-1 at both ends of the surface of the machine body 1 to provide a guiding channel for sheet metal conveying, ensuring that the sheet metal moves along the preset path to the stamping station, and avoiding deviation during conveying that causes stamping position deviation.

[0031] One of the pair of conveying rollers 6-2 on one side of the machine body 1 is electrically driven to rotate, which can generate a continuous pushing force on the sheet metal and smoothly convey the sheet metal along the moving groove 6-1 to the mold of the lower stamping seat 5-4. The pushing speed can be precisely matched with the rotation stamping rhythm of the stamping component 5 to ensure that the length of the sheet metal conveyed each time meets the requirements of the stamping process, and realize continuous feeding combined with continuous stamping.

[0032] The discharge port 6-3 on one side of the machine body 1 has an inclined bottom structure. After the window guide rail is formed by the cutting process and comes out downward from the stamping component 5, it can automatically slide out of the machine body 1 along the bottom surface of the inclined discharge port 6-3. There is no need for manual reaching into the equipment to retrieve the material, which improves the discharge efficiency and avoids operational safety hazards. The angle of the inclined structure is adapted to ensure that the workpiece slides out smoothly by gravity, while avoiding collision damage to the workpiece due to excessive sliding speed. At the same time, it is convenient to set up a collection device below the discharge port 6-3 to realize the centralized collection of finished products and reduce the workload of subsequent sorting. In addition, the spacing of the conveying rollers 6-2 can be adjusted according to the thickness of the sheet material to ensure stable pushing of sheets of different thicknesses; the inner wall of the moving trough 6-1 can be made of a smooth material to reduce the frictional resistance during sheet material conveying and avoid scratches on the sheet material surface.

[0033] During operation, the conveyor roller 6-2 pushes the sheet metal to the stamping station, and after stamping, the workpiece slides out from the discharge port 6-3. Continuous conveying in coordination with the stamping rhythm and inclined discharge ensure safety and efficiency. All components work together to complete the continuous conveying of sheet metal and the output of finished products, providing a stable supply of raw materials and a finished product output channel for the continuous forming of the stamping assembly 5, and ensuring the overall production efficiency of the equipment.

[0034] For example, such as Figure 4 As shown, the outer surfaces of the upper stamping seat 5-3 and the lower stamping seat 5-4 have a polygonal structure.

[0035] In some examples, the outer surfaces of the upper stamping seat 5-3 and the lower stamping seat 5-4 are polygonal. The polygonal structure allows the mold mounting slots 5-5 to be more regularly distributed on the surface of the stamping seat, with each surface corresponding to a mold mounting position. This ensures that the spacing between each mold mounting slot 5-5 is uniform and the position is accurate, avoiding mold positioning deviations that may occur with circular structures.

[0036] For example, such as Figure 2 As shown, the surfaces of the conveying rollers 6-2 are all made of frosted anti-slip material, and the spacing between the conveying rollers 6-2 is matched with the thickness of the raw material plate.

[0037] In some examples, the surface of the conveyor roller 6-2 is made of a frosted anti-slip structure, which can increase the friction between the conveyor roller 6-2 and the raw material sheet, prevent the sheet from slipping during the conveying process due to insufficient pushing force or a smooth surface, ensure that the sheet is stably conveyed to the stamping station at a preset speed, and avoid deviation in the conveying length of the sheet due to slippage, which would affect the stamping accuracy.

[0038] In actual use: According to the processing requirements of the window guide rail, the corresponding stamping dies for the corresponding process are installed in the mold mounting slots 5-5 of the upper stamping seat 5-3 and the lower stamping seat 5-4 respectively. The vertical linear drive in the machine body 1 is started, so that the pressure support seat 5-12 rises and fits against the bottom of the lower stamping seat 5-4. The raw material sheet is placed between the conveying rollers 6-2 of the feeding and discharging assembly 6. The electric drive of the conveying rollers 6-2 rotates, pushing the sheet along the moving groove 6-1 on the surface of the machine body 1 onto the mold of the lower stamping seat 5-4. The vertical linear drive within the upper cavity 3 and lower cavity 4 is activated, causing the vertical moving seat 5-2 to approach the upper and lower stamping seats 5-4. The telescopic positioning pin 5-6 of the lower stamping seat 5-4, under the action of the spring 5-7, inserts into the positioning sleeve 5-8 of the upper stamping seat 5-3, ensuring precise mold alignment. Simultaneously, the telescopic cylinder 5-14 of the vertical moving seat 5-2 drives the positioning block 5-15 to insert into the positioning groove 5-11 of the limit seat 5-10, fixing the stamping seat position. After one stamping cycle, the positioning block 5-15 retracts, and the electric drive rotates the upper and lower stamping seats 5-4 to switch to the next mold, repeating the stamping action until all forming processes are completed. Finally, the process switches to the cutting mold. After cutting, the pressure support seat 5-12 descends, and the forming guide rail falls from the through-hole 5-1, sliding out of the machine body 1 through the inclined discharge port 6-3. Simultaneously, the conveying roller 6-2 continuously pushes new sheet metal, achieving continuous processing.
