[0003] In the existing technology, the stamping and trimming mechanism of the outer ring of automotive wheel hub bearings mostly adopts a simple upper and lower stamping structure, which is not convenient for guiding during stamping and makes it impossible to ensure the stability of stamping. Moreover, during use, there is a lack of effective buffer structure during the stamping process, and the impact force acts directly on the workpiece, which easily causes elastic deformation of the outer ring of the automotive wheel hub bearing.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example 1:
[0018] Please see Figure 1-5 The present invention provides the following technical solution: a stamping and trimming mechanism for automotive parts, including a worktable 1, a support frame 2 fixedly connected to one end of the worktable 1, an electric telescopic rod 3 fixedly connected to the middle of the support frame 2, an annular cutter 4 installed below the electric telescopic rod 3, a support platform 5 fixedly connected to the middle of the worktable 1, a positioning column 6 installed above the support platform 5, the electric telescopic rod 3 and the annular cutter 4 connected by a stabilizing component 7, and the support platform 5 and the positioning column 6 connected by a buffer component 8; The stabilizing component 7 includes a stabilizing plate 71, which is fixedly connected to the lower part of the electric telescopic rod 3. The two ends of the stabilizing plate 71 are symmetrically and fixedly connected to stabilizing slide rods 72. The stabilizing slide rods 72 cooperate with the guide holes on the support frame 2 to achieve a sliding connection. A stop block 73 is fixedly connected to the upper part of the stabilizing slide rods 72. The stabilizing plate 71 and the annular cutter 4 are fixed by the fixing component 74.
[0019] Specifically, the fixing component 74 includes a square insert 741, which is tightly inserted into the bottom of the stabilizing plate 71. The bottom of the square insert 741 is fixedly connected to the annular cutter 4. The two ends of the stabilizing plate 71 are threadedly connected to fixing screws 742. One end of the fixing screw 742 is rotatably connected to a fixing block 743 through a bearing. The fixing block 743 and the stabilizing plate 71 are in contact and slidably connected. The other end of the fixing screw 742 is fixedly connected to an anti-slip handle 744.
[0020] By adopting the above technical solution, during the downward punching process of the annular cutter 4, the stabilizing slide rod 72 plays a guiding and limiting role, enabling it to slide stably; rotating the anti-slip handle 744 drives the fixing screw 742 to rotate, which in turn drives the fixing block 743 to move, separating it from the fixing hole on one side of the square insert 741. Thus, the annular cutter 4 can be removed by separating the square insert 741 from the stabilizing plate 71 for easy replacement.
[0021] Specifically, a rubber washer 745 is fitted onto the surface of the fixing screw 742 located on the outer end of the stabilizing plate 71.
[0022] By adopting the above technical solution, the rubber gasket 745 can improve the fastening force and the stability after fixing when the anti-slip throttle 744 and the stabilizing plate 71 come into contact.
[0023] Specifically, one side of the square insert 741 has a fixing hole that can be tightly inserted into the fixing block 743.
[0024] By adopting the above technical solution, the fixing hole facilitates the insertion of the fixing block 743 and fixes the square insert block 741.
[0025] In this embodiment: During punching, the annular cutter 4 moves downward and is guided and limited by the stabilizing slide rod 72, allowing it to slide stably. When changing the cutter, rotating the anti-slip handle 744 rotates the fixing screw 742, which in turn causes the fixing block 743 to exit from the fixing hole on one side of the square insert 741. At this time, the square insert 741 and the stabilizing plate 71 separate, and the annular cutter 4 can be removed for replacement.
[0026] Example 2: The difference between this embodiment and embodiment 1 is that: specifically, the buffer assembly 8 includes a buffer plate 87, which is fixedly connected to the bottom of the positioning post 6. Limiting slide rods 81 are evenly installed along the circumference of the buffer plate 87. An installation block 83 is installed below the limiting slide rod 81. A buffer spring 82 is sleeved on the surface of the limiting slide rod 81 located at the middle end between the buffer plate 87 and the support platform 5.
[0027] By adopting the above technical solution, during punching, the buffer plate 87 drives the limiting slide rod 81 to move on the support platform 5 to compress the buffer spring 82, thereby buffering the punching force.
[0028] Specifically, a second connecting screw 86 is fixedly connected to the upper part of the limiting slide rod 81, and the second connecting screw 86 is threadedly connected to the buffer plate 87. A first connecting screw 84 is fixedly connected to the lower part of the limiting slide rod 81, and the first connecting screw 84 is threadedly connected to the mounting block 83.
[0029] By adopting the above technical solution, the assembly between the limiting slide bar 81 and the buffer plate 87 is facilitated by connecting screw 2 86, and the assembly between the limiting slide bar 81 and the mounting block 83 is facilitated by connecting screw 1 84.
[0030] Specifically, an auxiliary rod 85 is fixedly connected to the surface of the mounting block 83.
[0031] By adopting the above technical solution, the auxiliary rod 85 is designed to facilitate the rotation of the mounting block 83.
[0032] In this embodiment: During punching, the buffer plate 87 drives the limiting slide rod 81 to move on the support platform 5 to compress the buffer spring 82, thereby buffering the punching force. This allows the device to buffer the punching force during use, improving its practicality.
[0033] The working principle and usage process of this utility model are as follows: This mechanism is specifically designed for punching the outer ring of automotive wheel hub bearings. During operation, the workpiece is first placed on the positioning pin 6, and then the electric telescopic rod 3 is activated to drive the annular cutter 4 to move downwards to perform punching. During the punching process, the stabilizing component 7 provides guidance for the cutter, ensuring smooth punching; the buffer component 8 absorbs and relieves the punching pressure, thus protecting the workpiece and the mechanism.
[0034] The steps for using the stabilizing component 7 are as follows: During punching, the annular cutter 4 moves downward and is guided and limited by the stabilizing slide rod 72, allowing it to slide stably. When changing the cutter, rotate the anti-slip handle 744, which drives the fixing screw 742 to rotate, thereby causing the fixing block 743 to exit from the fixing hole on one side of the square insert 741. At this time, the square insert 741 and the stabilizing plate 71 separate, and the annular cutter 4 can be removed for replacement.
[0035] The operation steps of the buffer assembly 8 are as follows: During punching, the pressure on the workpiece is transmitted to the buffer plate 87 via the positioning pin 6. The buffer plate 87 drives the limiting slide rod 81 to slide downward along the support platform 5, simultaneously compressing the buffer spring 82. The impact energy is absorbed by the elastic deformation of the spring, thereby achieving effective punching pressure buffering and improving the stability of processing and the quality of the workpiece.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
