Description

Technical Field

[0001] This utility model belongs to the field of busbar trunking processing technology, specifically relating to a busbar trunking processing stamping equipment. Background Technology

[0002] Busbar trunking plays a crucial role in power transmission. Before the finished busbar trunking is produced, the raw materials need to be stamped using stamping equipment to form a trough-shaped finished busbar trunking product.

[0003] A related technology (publication number CN219966136U) discloses a stamping equipment for busbar trunking processing. Through the cooperation of a buffer rod, buffer wheel, connecting plate, short rod, buffer rod, buffer spring, short plate, and connecting shell, it has the advantage of positioning the busbar trunking, preventing wobbling during stamping and making the busbar trunking more stable, thus enabling better stamping of the busbar trunking. Through the cooperation of a mounting plate, fan, suction pipe, and suction cup, it has a buffer protection function for the mold during stamping, reducing the downward stamping force, protecting the mold, improving the mold's service life, and increasing practicality.

[0004] However, existing stamping equipment lacks the function of limiting and centering the raw material when stamping. If the raw material sheet is skewed relative to the stamping die, it will cause the inner groove of the busbar groove of the finished product after stamping to be skewed, reducing the pass rate of stamping finished products. Rework will also affect the overall stamping progress and efficiency. Utility Model Content

[0005] Existing stamping equipment lacks a limiting and centering function for raw materials during stamping. If the raw material sheet is misaligned relative to the stamping die, the inner groove of the finished busbar groove will be skewed, reducing the yield rate of stamped products. Rework will further affect the overall stamping progress and efficiency. This invention provides a busbar groove stamping equipment that can limit and center the raw material sheet relative to the stamping groove, ensuring complete front-to-back symmetry of the raw material relative to the stamping groove during stamping. This guarantees that the inner groove of the finished busbar groove will be symmetrical, avoiding the problem of the raw material sheet being misaligned relative to the stamping die, ensuring a high yield rate, preventing rework and maintaining normal production efficiency. The specific technical solution is as follows:

[0006] A busbar trunking processing stamping equipment includes a stamping table with two through slots symmetrically formed from front to back. A limit rod is installed in each through slot from front to back. A movable arm is slidably sleeved on the limit rod. A limit plate is installed at the end of the movable arm. A stamping groove is formed in the middle of the upper surface of the stamping table along the horizontal direction. The two limit plates are symmetrically arranged from front to back with respect to the stamping groove. The two limit plates can move symmetrically from front to back through a drive assembly.

[0007] The drive assembly includes a rotating shaft rotatably connected to the lower surface of the stamping table. A turntable is fixedly mounted on the rotating shaft. One end of two connecting rods is rotatably connected to the turntable. The other ends of the two connecting rods are rotatably connected to the bottom ends of the two limiting plates, and the two connecting rods are symmetrically arranged with respect to the center of the rotating shaft.

[0008] In the above technical solution, a gear is fixedly installed on the rotating shaft, a rack is meshed with the front side wall of the gear, the rack moves horizontally through a guide assembly, and a movable frame is installed on the front side wall of the rack.

[0009] In the above technical solution, the guide assembly includes two mounting seats that are fixedly and vertically installed on the lower surface of the stamping table, a light rod is fixedly installed between the two mounting seats, and the movable frame is slidably sleeved on the light rod.

[0010] In the above technical solution, one end of the support rod is installed on the mobile frame, and the other end of the support rod is installed with a sleeve. The sleeve is slidably provided with a positioning pin from front to back. A spring is sleeved on the positioning pin, and the two ends of the spring are respectively connected to the positioning pin and the side wall of the sleeve.

[0011] In the above technical solution, a fixing strip is installed on the front side wall of the stamping table in the horizontal direction, and a number of positioning holes are equally spaced on the front side of the fixing strip, and the rear end of the positioning pin is embedded in the cavity of one of the positioning holes.

[0012] The sleeve is slidably fitted onto the fixing strip.

[0013] In the above technical solution, columns are vertically installed at the four corners of the stamping table, a frame is fixedly installed at the top of the columns, a cylinder is installed in the middle of the frame, and the output end of the cylinder is connected to the stamping plate.

[0014] In the above technical solution, the stamping plate and the stamping groove are arranged vertically and vertically in correspondence.

[0015] In the above technical solution, a support frame is provided at the bottom of the stamping table.

[0016] The busbar trunking processing and stamping equipment of this utility model has the following advantages compared with the prior art:

[0017] I. Existing stamping equipment lacks a limiting and centering function for raw materials during stamping. If the raw material sheet is skewed relative to the stamping die, the inner groove of the finished busbar groove will be misaligned, reducing the pass rate of stamped products. Rework will also affect the overall stamping progress and efficiency. This utility model addresses this problem by using two symmetrically arranged limiting plates to limit and center the raw material sheet relative to the stamping groove. This ensures that the raw material is completely symmetrical with respect to the stamping groove during stamping, thereby ensuring that the inner groove of the finished busbar groove is symmetrical after stamping. This avoids the problem of the raw material sheet being skewed relative to the stamping die, guarantees the pass rate of stamped products, avoids rework affecting the overall stamping progress, and ensures normal production efficiency.

[0018] Second, in this utility model, the circumferential rotation of the turntable can make the two limiting plates move closer or further away from each other by the same distance, thereby ensuring that the two limiting plates are always symmetrical with respect to the front and back of the stamping groove, that is, ensuring that the raw material plate positioned between the two limiting plates is always symmetrically set with respect to the stamping groove.

[0019] Third, this utility model uses two relatively movable limiting plates to limit and center raw material plates of different widths. The equipment has strong adaptability and can meet the stamping processing needs of busbars of different widths.

[0020] IV. This utility model can drive the gear to rotate by the horizontally moving rack, thereby driving the turntable to rotate. Furthermore, by positioning the moving frame, support rod, and sleeve at the fixed bar, the rack can be positioned after displacement, thus stabilizing the gear, shaft, and turntable after rotation. This ensures that the two limiting plates remain relatively stable and do not move after displacement.

[0021] V. This utility model, through the support rod and positioning pin, can position the sleeve at the positioning holes in different positions, thereby realizing the positioning of the movable frame and rack after translation.

[0022] In summary, this utility model can limit and center the raw material sheet relative to the stamping groove, ensuring that the raw material can be completely symmetrical with respect to the stamping groove during stamping. This ensures that the finished busbar groove after stamping can achieve symmetrical inner groove, avoids the problem of the raw material sheet being skewed relative to the stamping die, ensures the qualified rate of stamped products, avoids rework and re-work affecting the overall stamping process progress, and ensures normal production efficiency.

Detailed Implementation

[0029] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0030] Main references Figures 1 to 5 As shown, a busbar trunking processing stamping equipment includes a stamping table 1. Two through slots 3 are symmetrically opened in the stamping table 1. Limiting rods 4 are installed in the through slots 3 from front to back. Moving arms 5 are slidably sleeved on the limiting rods 4. Limiting plates 6 are installed at the ends of the moving arms 5. A stamping groove 20 is opened in the middle of the upper surface of the stamping table 1 in the horizontal direction. The two limiting plates 6 are symmetrically arranged in front and back with respect to the stamping groove 20. The two limiting plates 6 can move symmetrically in front and back with respect to the stamping groove 20 through a drive assembly. The drive assembly includes a rotating shaft 9 rotatably connected to the lower surface of the stamping table 1 through bearings. A turntable 10 is fixedly installed on the rotating shaft 9. One end of two connecting rods 11 is rotatably connected to the turntable 10. The other ends of the two connecting rods 11 are rotatably connected to the bottom ends of the two limiting plates 6 through bearings. The two connecting rods 11 are symmetrically arranged with respect to the center of the rotating shaft 9.

[0031] The rotation of turntable 10 causes one end of the two connecting rods 11 rotatably connected to turntable 10 to rotate synchronously relative to the rotating shaft 9, so that the moving arm 5 rotatably connected to the other end of the connecting rod 11 moves along the limiting rod 4, so that the two limiting plates 6 move towards the middle synchronously until the side walls of the two limiting plates 6 position the raw material plate on the stamping groove 20. Since the two limiting plates 6 are symmetrically arranged with respect to the stamping groove 20, the raw material plate can be limited by the movement of the two limiting plates 6 towards the middle, so as to achieve the centering and limiting of the raw material plate on the stamping groove 20.

[0032] Main references Figure 3 and Figure 4 As shown, a gear 12 is fixedly installed on the rotating shaft 9. A rack 13 is meshed with the front side wall of the gear 12. The rack 13 moves horizontally through a guide assembly. A movable frame 14 is installed on the front side wall of the rack 13. The rotation of the gear 12 can be achieved by the translation of the rack 13, thereby realizing the rotation of the rotating shaft 9 and the turntable 10. The guide assembly includes two mounting seats 15 fixedly and vertically installed on the lower surface of the stamping table 1. A smooth rod 16 is fixedly installed between the two mounting seats 15. The movable frame 14 is slidably sleeved on the smooth rod 16. When the movable frame 14 moves, it can move horizontally without deflection under the guidance of the smooth rod 16.

[0033] Main references Figure 1 , Figure 2 and Figure 5 As shown, a support rod 17 is mounted on one end of the movable frame 14, and a sleeve 25 is mounted on the other end of the support rod 17. A positioning pin 18 is slidably installed through the sleeve 25 from front to back. A spring 19 is sleeved on the positioning pin 18. The two ends of the spring 19 are connected to the positioning pin 18 and the side wall of the sleeve 25, respectively. When the movable frame 14 moves, it can drive the sleeve 25 to move synchronously. The positioning pin 18 and the spring 19 can be used to position the sleeve 25 after it has moved. A fixing strip 7 is installed on the front side wall of the stamping table 1 in the horizontal direction. Several positioning holes 8 are equally spaced on the front side of the fixing strip 7. The rear end of the positioning pin 18 is embedded in the cavity of one of the positioning holes 8. The sleeve 25 is slidably sleeved on the fixing strip 7. The positioning of the sleeve 25 by the positioning pin 18 and the spring 19 can realize the positioning of the movable frame 14.

[0034] When the movable frame 14 moves, it can drive the support rod 17 to move horizontally in sync. At this time, the sleeve 25 moves along the fixed bar 7. When the movable frame 14 stops moving, the external force on the positioning pin 18 is removed. With the help of the spring force of the spring 19, the positioning pin 18 is re-embedded in the cavity of the corresponding positioning hole 8, so as to realize the positioning of the sleeve 25 at this time. That is, the positioning of the support rod 17, the movable frame 14, the rack 13, the gear 12 and the two limit plates 6 after displacement is realized.

[0035] Main references Figure 1 As shown, four columns 21 are vertically installed at the four corners of the stamping table 1. A frame 22 is fixedly installed at the top of the column 21. A cylinder 23 is installed in the middle of the frame 22. The output end of the cylinder 23 is connected to a stamping plate 24. The stamping plate 24 is arranged vertically and vertically with the stamping groove 20. The cylinder 23 drives the stamping plate 24 to move downward, so as to force the center of the raw material plate after centering and limiting downward to press and fit against the inner cavity of the stamping groove 20. The front and rear horizontal edges of the raw material plate still remain on the stamping table 1, thereby realizing the stamping of the raw material plate into a U-shape in the inner cavity of the stamping groove 20.

[0036] In addition, a support frame 2 is provided at the bottom of the stamping table 1. The support frame 2 ensures that the overall height of the equipment is sufficient to allow for operation, and casters are provided at the bottom of the support frame 2 to facilitate the overall movement of the equipment.

[0037] It is worth noting that the cylinder 23 used in this application is a commonly used self-locking cylinder on the market, whose output end can stay at any position and be locked; the above-mentioned existing components will not be described in detail here.

[0038] The working principle of the busbar trunking stamping equipment in this embodiment is as follows:

[0039] The raw material plate to be stamped is placed on the stamping groove 20. With the help of external force, the positioning pin 18 is pulled outward and caused to disengage from the inner cavity of the corresponding positioning hole 8. At this time, the spring 19 is forced to deform and compress, driving the moving frame 14 to move horizontally. This causes the rack 13 to move horizontally in sync, causing the gear 12 to rotate circumferentially. The gear 12 drives the rotating shaft 9 and the turntable 10 to rotate synchronously, causing one end of the two connecting rods 11 rotatably connected on the turntable 10 to rotate synchronously relative to the rotating shaft 9. This causes the moving arm 5 rotatably connected to the other end of the connecting rod 11 to move along the limiting rod 4, so that the two limiting plates 6 move towards the middle synchronously until the side walls of the two limiting plates 6 position the raw material plate on the stamping groove 20. Since the two limiting plates 6 are symmetrically arranged with respect to the stamping groove 20, the moving of the two limiting plates 6 towards the middle can limit the raw material plate, thus achieving the centering and limiting of the raw material plate on the stamping groove 20.

[0040] When the movable frame 14 moves, it can drive the support rod 17 to move horizontally in sync. At this time, the sleeve 25 moves along the fixed bar 7. When the movable frame 14 stops moving, the external force on the positioning pin 18 is removed. With the help of the spring force of the spring 19, the positioning pin 18 is re-embedded in the cavity of the corresponding positioning hole 8, so as to realize the positioning of the sleeve 25 at this time. That is, the positioning of the support rod 17, the movable frame 14, the rack 13, the gear 12 and the two limit plates 6 after displacement is realized.

[0041] The cylinder 23 drives the stamping plate 24 to move downward, so as to force the center of the raw material plate after centering and limiting to press and fit against the inner cavity of the stamping groove 20. The front and rear horizontal edges of the raw material plate remain on the stamping table 1, thereby realizing the stamping of the raw material plate into a concave shape in the inner cavity of the stamping groove 20.

[0042] This invention can limit and center the raw material sheet relative to the stamping groove 20, ensuring that the raw material can be completely symmetrical with respect to the stamping groove 20 during stamping. This ensures that the finished busbar groove after stamping can achieve symmetrical inner groove, avoids the problem of the raw material sheet being skewed relative to the stamping die, ensures the qualified rate of stamped products, avoids rework and re-work affecting the overall stamping process progress, and ensures normal production efficiency.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
