Abstract
Description
Technical Field
[0001] This utility model relates to the field of blanking mold technology, and in particular to a blanking mold for a motor connecting plate. Background Technology
[0002] As a key forming equipment in the field of motor manufacturing, the blanking die for motor connecting plates has the core function of accurately separating the sheet metal of motor connecting plates along a preset closed contour line through the stamping force, thereby efficiently obtaining connecting plate blanks that meet the design size and shape requirements.
[0003] In the production of motor connection plates, if the blanking die cannot effectively constrain the workpiece, the workpiece is prone to positional displacement during stamping, resulting in significant errors between product dimensions and design requirements. This leads to a substantial decrease in the finished product qualification rate, wasting raw materials, increasing production costs, and potentially affecting the overall assembly accuracy of the motor due to dimensional discrepancies, thus reducing motor performance and stability. Furthermore, when producing connection plates of different specifications, if the die cannot be flexibly adjusted for adaptation, each specification change requires complex and time-consuming equipment debugging, causing prolonged production line downtime and reducing production efficiency. In addition, if the waste generated during stamping is not properly handled, it will accumulate haphazardly in the production area, occupying valuable workspace, increasing daily cleaning and maintenance costs, and potentially causing slips, cuts, and other safety accidents, disrupting the orderliness and safety of the production environment. Utility Model Content
[0004] The purpose of this utility model is to solve the problems in the background art by proposing a blanking mold for a motor connecting plate.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A blanking die for a motor connecting plate includes a lower die and a fixing mechanism. The fixing mechanism includes two first slide bars welded to the top of the lower die. The two first slide bars are slidably connected to a movable clamp. An L-shaped rod is fixedly connected to the side wall of the movable clamp. The side wall of the L-shaped rod away from the movable clamp is threaded through and connected to a bidirectional threaded rod. A first motor is fixedly installed on the side wall of the lower die. Multiple support rods are fixedly connected to the bottom of the lower die. A base is fixedly connected to the bottom of the multiple support rods. A lifting mechanism is provided on the top of the base.
[0007] Preferably, the lifting mechanism includes two support frames fixedly connected to the top of the base, a sliding rod fixedly connected to the inner wall of the top of the support frame, a threaded rod rotatably connected through the top of the support frame, a second motor fixedly connected to the top of the support frame, and a lifting rod sleeved and threadedly connected to the threaded rod.
[0008] Preferably, an upper mold base is fixedly connected to the side wall of the lifting rod, an upper mold is welded to the bottom of the upper mold base, cutting edges are provided around the bottom of the upper mold, and a collecting mechanism is provided on the top of the base.
[0009] Preferably, the collection mechanism includes two second slide bars fixedly connected to the top of the base, a support plate slidably connected to the top of the two second slide bars, a waste guide plate fixedly connected to the top of the support plate, a fixing plate fixedly connected to the top of the base, and an electric push rod fixedly installed on the side wall of the fixing plate.
[0010] Preferably, the output end of the first motor is fixedly connected to one end of the bidirectional threaded rod, the output end of the second motor is fixedly connected to the top of the threaded rod, and the telescopic end of the electric push rod is fixedly connected to the side wall of the support plate.
[0011] Preferably, the lower mold has an opening at its center, and its shape matches that of the upper mold base.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model, through the setting of a fixing mechanism, not only achieves precise positioning and stable clamping of the motor connecting plate workpiece, but also flexibly adapts to different sizes of sheet metal through the sliding of the moving fixture along the first slide bar and the adjustment driven by the bidirectional threaded rod. Whether the motor connecting plate sheet metal is small or large, during stamping, the first motor drives the bidirectional threaded rod to rotate, causing the moving fixture to adjust its position according to the sheet metal size, thereby firmly constraining workpieces of different sizes in a predetermined position. This ensures precise separation of the connecting plate blank along the preset contour line, significantly improving the dimensional accuracy of the product.
[0014] 2. This utility model, by setting up a collection mechanism, can collect waste generated during the stamping process in a timely and convenient manner. This effectively prevents waste from piling up randomly in the production area, saving valuable working space and reducing cleaning and maintenance costs. At the same time, it eliminates safety hazards such as slips and cuts caused by scattered waste, maintaining an orderly and safe production environment and providing a good guarantee for efficient production in the motor manufacturing industry.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figure 1-6 A blanking die for a motor connecting plate includes a lower die 1 and a fixing mechanism. The fixing mechanism includes two first slide bars 2 welded to the top of the lower die 1. The two first slide bars 2 are arranged in parallel and extend along the length direction of the top of the lower die 1. The two first slide bars 2 are slidably connected to a movable clamp 3. The bottom of the movable clamp 3 is provided with a groove that matches the first slide bars 2 to achieve sliding engagement. The corresponding side wall of the movable clamp 3 is provided with a groove. The shape of the groove matches the edge of the motor connecting plate workpiece to facilitate clamping the workpiece.
[0024] An L-shaped rod 4 is fixedly connected to the side wall of the movable clamp 3. A two-way threaded rod 5 is threaded through the side wall of the L-shaped rod 4 away from the movable clamp 3. The two-way threaded rod 5 has left-hand threads and right-hand threads at both ends. One end of the two-way threaded rod 5 passes through the lower mold 1, and the other end is fixedly connected to the lower mold 1. A first motor 7 is fixedly installed on the side wall of the lower mold 1. The output end of the first motor 7 is fixedly connected to one end of the two-way threaded rod 5. Multiple support rods 8 are fixedly connected to the bottom of the lower mold 1. A base 9 is fixedly connected to the bottom of the multiple support rods 8. A lifting mechanism is provided on the top of the base 9.
[0025] The lifting mechanism includes two support frames 10 fixedly connected to the top of the base 9. The support frames 10 are in the shape of a "door". A sliding rod 12 is fixedly connected to the inner top wall of one of the support frames 10. A threaded rod 11 is rotatably connected through the top of the other support frame 10. A lifting rod 14 is sleeved on the threaded rod 11 and threadedly connected to it. The sliding rod 12 passes through the lifting rod 14 and slides with it. The bottom of the sliding rod 12 is fixedly connected to the top of the base 9. The bottom of the threaded rod 11 is rotatably connected to the top of the base 9. A second motor 13 is fixedly installed on the top of the support frame 10. The output end of the second motor 13 is fixedly connected to the top of the threaded rod 11.
[0026] The upper mold base 15 is fixedly connected to the corresponding side wall of the two lifting rods 14. The upper mold 16 is welded to the bottom of the upper mold base 15. The bottom of the upper mold 16 is provided with cutting edges 17 around the perimeter. The top of the base 9 is provided with a collecting mechanism, which includes two second slide bars 18 fixedly connected to the top of the base 9. The two second slide bars 18 are arranged in parallel.
[0027] The top of the two second slide bars 18 is slidably connected to a support plate 19. The top of the support plate 19 is fixedly connected to a waste guide plate 20. The waste guide plate 20 has an opening at its end and is inclined to facilitate the waste to slide out. The waste guide plate 20 is located below the opening 6. The top of the base 9 is fixedly connected to a fixing plate 21. An electric push rod 22 is fixedly installed on the side wall of the fixing plate 21. The telescopic end of the electric push rod 22 is fixedly connected to the side wall of the support plate 19.
[0028] The first motor 7, the second motor 13, and the electric push rod 22 are all electrically connected to the external control system. The lower mold 1 has an opening 6 at its center, and the shape of the opening 6 matches that of the upper mold base 15.
[0029] The detailed working process of this utility model is as follows:
[0030] The sheet metal is placed on the lower mold 1, and the first motor 7 is started through the external control system. The output end of the first motor 7 drives the bidirectional threaded rod 5 to rotate. Since the two ends of the bidirectional threaded rod 5 are respectively provided with left-hand and right-hand threads, and are threadedly connected to the L-shaped rod 4 on the side wall of the movable fixture 3, the two movable fixtures 3 will slide towards or away from each other along the first slide bar 2 when rotating. When the movable fixture 3 approaches the sheet metal, the groove on its side wall that matches the edge of the sheet metal will hold the workpiece, achieving precise positioning and firm fixation, and preventing the workpiece from shifting during the stamping process.
[0031] According to the stamping process requirements, the second motor 13 is started through an external control system. The output end of the second motor 13 drives the threaded rod 11 to rotate. The threaded rod 11 is threadedly connected to the lifting rod 14, while the lifting rod 14 is slidably engaged with the slide rod 12. When the threaded rod 11 rotates, the lifting rod 14 moves up and down along the slide rod 12, thereby driving the upper die holder 15 and the upper die 16, which are fixed to the side walls of the two lifting rods 14, to adjust their height, accurately control the die closing height, and prepare for stamping.
[0032] After the workpiece is fixed and the mold height is adjusted, the stamping program is started. The upper mold 16 moves downward under the drive of the lifting mechanism, and the cutting edges 17 around its bottom cooperate with the lower mold 1 to apply a stamping force to the fixed motor connecting plate material, separating the material along the preset closed contour line, and completing the blanking and forming of the motor connecting plate.
[0033] The waste material generated during the stamping process falls through the opening 6 in the center of the lower die 1 and onto the inclined waste guide plate 20 below the opening 6. Subsequently, the electric push rod 22 is activated by the external control system. The telescopic end of the electric push rod 22 pushes the support plate 19 to slide along the second slide bar 18, which in turn moves the waste guide plate 20. Since the waste guide plate 20 is inclined and has an opening at its end, the waste material slides down the plate under the action of gravity and is eventually collected in the designated location, thus avoiding the accumulation of waste material that may affect the production environment and operational safety.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
