[0032] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a one-time stamping device for a bearing cover plate, including a base 1, which serves as the basic support structure of the entire device, provides an installation position for other components, and bears the pressure and impact force during the stamping process. The top of the base 1 is fixedly connected with a support column 2, which guides and supports the up and down movement of a movable plate 4, ensuring that the movable plate 4 can move vertically stably. The outer wall of the top of the support column 2 is slidably connected with the movable plate 4, which is connected to the output shaft of the hydraulic pump and moves up and down under the drive of the hydraulic pump, driving the upper forming mold 72 to perform a stamping operation. The top of the support column 2 is fixedly connected with a support plate 3 for installation. A hydraulic pump is provided, and a stable support is provided for the hydraulic pump. A hydraulic pump is arranged on the top of the support plate 3. The outer wall of the output shaft of the hydraulic pump passes through and slides on the inner wall of the top of the support plate 3. The bottom end of the output shaft of the hydraulic pump is fixedly connected to the top of the movable plate 4. The function of the hydraulic pump is to provide power, and the movable plate 4 is driven up and down by the telescopic movement of its output shaft. It is an existing structure and can be implemented by technicians in this field. Since it is an existing technology, it will not be described in detail in this case. An installation component is provided on the inner wall of the top of the base 1. The installation component includes a lower molding die 51, which cooperates with the upper molding die 72 to stamp the bearing cover plate.

[0033] Furthermore, the outer wall of the bottom end of the lower molding die 51 slides on the inner wall of the top end of the base 1, and a limiting groove 53 is opened on the outer side of the bottom end of the lower molding die 51. The inner wall of the base 1 is slidably connected to the limiting plate 52, and the limiting plate 52 is inserted into the inner wall of the limiting groove 53 through cooperation with the rotating rod 54, so that the lower molding die 51 can be quickly clamped and fixed to ensure its stable position during the stamping process. At the same time, different specifications or types of bearing cover plates can be quickly switched, which effectively promotes the optimization of the production process and the improvement of efficiency, and ensures the rapid switching and efficient operation of the production line.

[0034] Reference Figure 2 The limiting plates 52 are provided with multiple groups, and the inner walls of the rear sides of the multiple groups of limiting plates 52 are penetrated and slidably connected with stabilizing rods 56 to provide guidance for the movement of the multiple groups of limiting plates 52 to ensure that they can slide smoothly. The outer walls of the stabilizing rods 56 are fixedly connected to the inner wall of the base 1, and the base 1 is provided with a rotating rod 54 near the front side of the limiting plates 52. The outer wall of the rotating rod 54 on one side near one group of limiting plates 52 is provided with a thread groove 1 55, and the inner wall of the front end of the limiting plate 52 is penetrated and threadedly connected to the outer wall of the thread groove 1 55. The outer wall of the side of the rotating rod 54 near the other group of limiting plates 52 is provided with a thread groove 2 57, and the inner wall of the front end of the other group of limiting plates 52 is penetrated and threadedly connected to the outer wall of the thread groove 2 57. The different thread grooves 1 55 and thread grooves 2 57 on both sides of the rotating rod 54 can drive the two groups of limiting plates 52 to move toward or away from each other at the same time when rotating, so as to achieve the clamping and loosening of the lower molding mold 51.

[0035] Reference Figure 2, Figure 3 and Figure 5 A limit assembly is provided on the right side of the base 1 near the outer wall of the rotating rod 54. The limit assembly includes a limit column 61. The left side of the limit column 61 is inserted into the right inner wall of the base 1. A tooth is provided on the left side of the limit column 61. The tooth is used to increase stability and work together with the fixed cylinder 62 to limit the rotation of the rotating rod 54. The right outer wall of the rotating rod 54 near the limit column 61 is fixedly connected with a fixed cylinder 62, which cooperates with the limit column 61 to limit the rotation of the rotating rod 54. At the same time, by cooperating with the limit rod 63, the limit column 61 can be limited. The outer wall of the limit column 61 slides on the inner wall of the fixed cylinder 62. A moving block is fixedly connected to the top right side of the limit column 61 to provide support for sliding and installation of the limit rod 63. The outer wall of the moving block passes through and is slidably connected to the inner wall at the top end of the fixed cylinder 62. The right side of the moving block passes through and is slidably connected to the limit rod 63.

[0036] Furthermore, the outer wall of the bottom end of the limit rod 63 slides on the upper inner wall of the fixed cylinder 62, and cooperates with the protrusion on the upper inner wall of the fixed cylinder 62 through the slot 65. Under the elastic force of the compression spring 64, the position of the limit column 61 is locked or unlocked. A slot 65 is provided at the left end of the lower side of the limit rod 63, and a protrusion is provided on the upper inner wall of the fixed cylinder 62 near the slot 65. The slot 65 and the protrusion cooperate with each other to lock or unlock the limit rod 63, thereby limiting the limit column 61. The limit column 61 and the fixed cylinder 62 are elastically connected by the compression spring 64, which provides elastic force for the limit column 61, so that it remains inserted into the inner wall of the base 1 when it is not limited, and helps it to reset when unlocked. A crank is provided on the right side of the rotating rod 54 to facilitate the operator to rotate the rotating rod 54.

[0037] Reference Figure 1 and Figure 4 , an auxiliary component is provided at the bottom end of the movable plate 4, and the auxiliary component includes a mounting column 71, which connects the movable plate 4 and the upper forming mold 72, and provides installation space for internal components such as the slide plate 73 and the resist column 74. The top of the mounting column 71 is fixedly connected to the bottom end of the movable plate 4, and the bottom end of the mounting column 71 is provided with an upper forming mold 72, which cooperates with the lower forming mold 51 to complete the stamping forming of the bearing cover plate. At the same time, through holes are opened in the upper forming mold 72 and the lower forming mold 51 for stamping the middle part of the bearing cover plate. The inner wall of the mounting column 71 is slidably connected with a slide plate 73, which connects the resist column 74 and the sliding column 75, and plays a role in transmitting pressure and buffering during the stamping process. The outer side of the bottom end of the slide plate 73 is fixedly connected with a resist column 74, and the resist column 74 is provided with multiple groups.

[0038] Furthermore, a rubber pad is provided at the bottom end of the support column 74, which contacts the stamping material on the lower molding die 51 during stamping to assist in positioning the material and to provide buffering and protection. A sliding column 75 is fixedly connected to the middle part of the bottom end of the slide plate 73, and the outer wall of the sliding column 75 slides on the mounting column 71 and the inner wall of the upper molding die 72 to provide guidance for the up and down movement of the slide plate 73, while being able to eject the stamped waste from the through hole in the upper molding die 72, thereby simplifying the waste handling process and improving the automation level and overall efficiency of the production line. The slide plate 73 is elastically connected to the mounting column 71 by a reset spring 76, which helps the slide plate 73 and the support column 74 to reset after the stamping is completed.

[0039] Working principle: During use, when it is necessary to replace the lower molding mold 51 of a different specification or type, pull the limit rod 63 outward so that the limit rod 63 drives the moving block to move, thereby driving the limit column 61 to slide out from the inner wall of the base 1 and squeeze the compression spring 64. At this time, press the limit rod 63 downward so that its bottom end slides on the inner wall of the fixed tube 62. Under the reverse action force of the compression spring 64, the slot 65 fits with the inner wall protrusion of the fixed tube 62, thereby releasing the restriction on the rotating rod 54.

[0040] At this time, the rotating rod 54 is rotated. Due to the setting of the thread groove 1 55 and the thread groove 2 57 on the outer side of the rotating rod 54, the two adjacent groups of limit plates 52 move toward each other under the guidance of the stabilizing rod 56, and are inserted into the limit groove 53 on the outer side of the bottom end of the lower molding mold 51, thereby clamping and fixing the lower molding mold 51. At this time, the installation of the lower molding molds 51 of different specifications or types is completed.

[0041] Then, the hydraulic pump is started, and the output shaft of the hydraulic pump is extended and retracted, driving the movable plate 4 to move up and down along the supporting column 2. When the movable plate 4 moves downward, it drives the mounting column 71 and the upper molding die 72 at the bottom thereof to move downward.

[0042] During the stamping process, the rubber pad at the bottom of the support column 74 first contacts the stamping material on the lower molding die 51 to assist in positioning the material and provide buffering protection. The upper molding die 72 cooperates with the lower molding die 51 to complete the stamping of the bearing cover plate. Waste generated during the stamping process can be discharged through the through hole in the mold.

[0043] After the punching is completed, the output shaft of the hydraulic pump retracts, driving the movable plate 4 to move upward. Under the action of the reset spring 76, the slide plate 73, the support column 74 and the slide column 75 are reset, and the slide column 75 can also push out the waste material after the punching from the through hole of the upper forming die 72.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
