Description

Technical Field

[0001] The utility model relates to the technical field of engine parts, in particular to an engine bearing shell bending and forming device. Background Technique

[0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines, external combustion engines, jet engines, electric motors, etc. For example, an internal combustion engine usually converts chemical energy into mechanical energy. An engine is applicable to power generating devices and can also refer to the entire machine including the power device. A bearing shell is the part that contacts the journal of a sliding bearing, and its shape is a semi-cylindrical surface in the shape of a tile, which is very smooth. Generally, it is made of wear-resistant materials such as bronze and antifriction alloy. In special cases, it can be made of wood, engineering plastics or rubber. There should be a very thin oil film between the bearing shell and the rotating shaft to play a lubricating role. Its function is to bear the acting force applied by the journal, keep the oil film stable, make the bearing work smoothly and reduce the friction loss of the bearing. The working principle of the bearing shell requires the bearing shell to have the following characteristics. First, it is necessary to use high-temperature resistant materials to make the bearing shell so that the bearing shell can withstand high temperatures. Second, it is necessary to polish the inner side of the bearing shell to be smooth enough to minimize the friction between the bearing shell and the rotating shaft. Finally, it is necessary to ensure the radian of the inner side of the bearing shell. Therefore, there is a particular need for an engine bearing shell bending and forming device.

[0003] However, in the existing engine bearing shell bending and forming device, when the bearing shell is bent and formed, due to the special shape of the bearing shell, it is very difficult to fix the bearing shell, resulting in the smooth progress of the bending work of the bearing shell during the processing, and the processing and forming rate of the bearing shell is low.

[0004] To solve the above problems, after retrieval, a patent with the publication number CN218395443U discloses a bearing shell bending and forming device. It is proposed in the text that "the bearing shell bending and forming device includes an operating table, on which a seat body and a longitudinal support plate are fixedly connected. A forming groove is provided on the seat body, and an oil groove is arranged on the forming groove. Two pairs of connecting blocks are fixedly connected to the seat body. A limiting plate is arranged on one side of the two pairs of connecting blocks. A telescopic rod and a compression spring are installed between the connecting block and the limiting plate, and the compression spring is sleeved on the telescopic rod. The top of the longitudinal support plate is fixedly connected with a first horizontal support plate, and a pressure-bearing component is fixedly connected to the first horizontal support plate. The pressure-bearing component includes a hydraulic rod, and a forming head is fixedly connected to the lower end of the hydraulic rod. An oil groove punch is arranged on the forming head. In the present utility model, the bearing shell material is fixed by the limiting plate. When the bearing shell is bent and formed, the front and back swinging of the bearing shell can be prevented, so that the bending work of the bearing shell can be carried out smoothly, effectively improving the processing and forming rate of the bearing shell." Although it can be fixed by the limiting plate, when the material is fixed by the compression spring and the telescopic rod, due to the contact between the forming head of the device and the material, the material will be driven to cause the compression spring to shake, affecting the clamping stability and resulting in an affected forming effect.

[0005] In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: an engine bearing shell bending and forming device, including an operating table 1 and a clamping mechanism 7. A forming base 2 is installed on one side of the surface of the operating table 1, a support frame 3 is fixedly connected to one side of the surface of the operating table 1, a hydraulic cylinder 4 is installed on one side of the surface of the support frame 3, one end of the hydraulic cylinder 4 is connected to a forming module 5, a forming groove 6 is opened on one side of the surface of the forming base 2, a clamping mechanism 7 is arranged on one side of the surface of the operating table 1, and a demolding mechanism 8 is arranged on one side of the surface of the operating table 1;

[0023] The clamping mechanism 7 includes a clamping base 701, a chute 702, a limiting rod 703, a bidirectional lead screw 704, a driving motor 705, a slider 706, and a clamping block 707. A clamping base 701 is installed on one side of the surface of the operating table 1. A chute 702 is provided on one side of the surface of the clamping base 701. A limiting rod 703 is arranged inside the chute 702. A bidirectional lead screw 704 is arranged inside the chute 702. One end of the bidirectional lead screw 704 is connected to a driving motor 705. Sliders 706 are respectively sleeved at both ends of the bidirectional lead screw 704. One end of each slider 706 is fixedly connected to a clamping block 707. Through the arrangement of the clamping base (701), the chute (702), the limiting rod (703), the bidirectional lead screw (704), the driving motor (705), the slider (706), and the clamping block (707), during use, after placing the engine bearing shell raw material on the surface of the forming base (2), turn on the driving motor (705). At this time, the driving motor (705) drives the bidirectional lead screw (704) to rotate inside the chute (702). Since the two sliders (706) are fitted inside the chute (702) and are threadedly sleeved at both ends of the bidirectional lead screw (704), and at the same time, both ends of the limiting rod (703) penetrate through the two sliders (706) and are fixedly connected to the clamping base (701), when the bidirectional lead screw (704) rotates inside the chute (702), the sliders (706) move closer to each other inside the chute (702) along the bidirectional lead screw (704) and the limiting rod (703). Thus, the sliders (706) drive the clamping blocks (707) to move closer to each other. The clamping blocks (707) moving closer to each other clamp and fix the engine bearing shell raw material.

[0024] Furthermore, both ends of the limiting rod 703 penetrate through the slider 706 and are fixedly connected to the clamping base 701. The driving motor 705 is installed at one end of the clamping base 701. Through the arrangement of the limiting rod 703, during use, when the bidirectional lead screw (704) rotates, the limiting rod 703 enables the slider 706 to move inside the chute 702 along the bidirectional lead screw 704 and the limiting rod 703.

[0025] Furthermore, the slider 706 is fitted inside the chute 702. There are two sets of sliders 706 which are respectively threadedly sleeved at both ends of the bidirectional lead screw 704. Through the arrangement of the slider 706, during use, when the slider 706 moves closer to each other inside the chute 702, it can drive the clamping block 707 to move closer to each other.

[0026] Furthermore, the bottom of the clamping block 707 is in contact with the top surface of the forming base 2. Through the arrangement of the clamping block 707, when the clamping block 707 moves closer to each other, it can clamp and fix the engine bearing shell raw material.

[0027] Furthermore, the demolding mechanism 8 includes a support plate 801, a telescopic rod 802, a return spring 803, a demolding block 804, and a handle 805. One side of the surface of the operating table 1 is fixedly connected to the support plate 801. One side of the surface of the support plate 801 is equipped with the telescopic rod 802. The surface of the telescopic rod 802 is sleeved with the return spring 803. The other end of the telescopic rod 802 is fixedly connected to the demolding block 804. One side of the surface of the demolding block 804 is fixedly connected to the handle 805. Through the settings of the support plate 801, the telescopic rod 802, the return spring 803, the demolding block 804, and the handle 805, when the bearing bush is formed, pull the handle 805. At this time, the handle 805 drives the demolding block 804 to move inside the forming groove 6. At the same time, the return spring 803 undergoes tensile deformation and the telescopic rod 802 extends. Since the demolding block 804 moves inside the forming groove 6, the demolding block 804 can extrude the engine bearing bush inside the forming groove 6 out of the forming groove 6. After releasing the handle 805, the return spring 803 undergoes elastic rebound deformation, thereby driving the demolding block 804 to return to its original position.

[0028] Furthermore, one end of the return spring 803 is fixedly connected to the support plate 801, and the other end of the return spring 803 is fixedly connected to the demolding block 804. Through the setting of the return spring 803, during use, when the return spring 803 undergoes elastic rebound deformation, it can drive the demolding block 804 to return to its original position, thus facilitating the next demolding operation.

[0029] Furthermore, one end of the demolding block 804 is fitted inside the forming groove 6. Through the setting of the demolding block 804, during use, the demolding block 804 moving inside the forming groove 6 can extrude the engine bearing bush inside the forming groove 6, thereby completing the demolding.

[0030] Working principle: After placing the raw material of the engine bearing shell on the surface of the forming base (2), turn on the driving motor (705). At this time, the driving motor (705) drives the bidirectional lead screw (704) to rotate inside the sliding groove (702). Since the two groups of sliders (706) are fitted inside the sliding groove (702) and are threadedly sleeved at both ends of the bidirectional lead screw (704), and at the same time, both ends of the limiting rod (703) penetrate through the two groups of sliders (706) and are fixedly connected to the clamping base (701), when the bidirectional lead screw (704) rotates inside the sliding groove (702), the sliders (706) move closer to each other along the bidirectional lead screw (704) and the limiting rod (703) inside the sliding groove (702). Thus, the sliders (706) drive the clamping blocks (707) to move closer to each other, and the clamping blocks (707) moving closer to each other clamp and fix the raw material of the engine bearing shell. Subsequently, turn on the hydraulic cylinder 4 to drive the forming module 5 to extrude the raw material of the engine bearing shell into the forming groove 6. When the bearing shell is formed, pull the handle 805. At this time, the handle 805 drives the demolding module 804 to move inside the forming groove 6, and at the same time, the return spring 803 undergoes tensile deformation and the telescopic rod 802 extends. Since the demolding module 804 moves inside the forming groove 6, the demolding module 804 can extrude the engine bearing shell inside the forming groove 6 out of the forming groove 6. After releasing the handle 805, the return spring 803 undergoes elastic deformation, thereby driving the demolding module 804 to return to its original position.
