Technical Field

[0001] This utility model relates to the field of parts bending processing, specifically to a bending device for an engine mounting plate. Background Technology

[0002] Engine mounting plates (protective plates) are metal or non-metal plates installed under the chassis of a car to protect core components such as the engine and transmission. Their main function is to prevent foreign objects such as stones and debris from directly impacting the bottom of the engine, while also reducing the entry of dust, mud, and other debris into the engine compartment.

[0003] While existing engine mounting plate bending devices can perform bending and forming of the mounting plate, they lack a precise and reliable positioning and mating structure between the stamping head and the mounting plate. They mostly rely on simple fixtures or manual assistance for positioning. During the bending process, the mounting plate is prone to displacement due to force, which affects the bending quality of the engine mounting plate and requires further improvement.

[0004] Therefore, it is necessary to invent a bending device for engine mounting plates. Utility Model Content

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Please refer to the appendix. Figures 1-6 This utility model provides an engine mounting plate bending device for bending an upper mounting plate 1. The upper mounting plate 1 has two positioning holes 2 and irregular holes 3 to facilitate positioning of the upper mounting plate 1. It includes a base plate 4, a support rod 5 symmetrically fixed at the top and rear end of the base plate 4, a top plate 6 horizontally fixed at the top of the support rod 5, a bending assembly fixed on the top plate 6, a material feeding assembly movably installed on the top of the base plate 4, and a positioning assembly fixed between the bending assembly and the material feeding assembly.

[0023] The bending assembly includes a vertically arranged first electric push rod 7. The bottom of the first electric push rod 7 is fixed at the middle of the top of the top plate 6. The bottom of the output shaft of the first electric push rod 7 is fixed with a first connecting plate 8. The bottom of the first connecting plate 8 is fixed with a bending head 9. Specifically, when the first electric push rod 7 is running, it can drive the bending head 9 to rise and fall through the first connecting plate 8, thereby performing stamping and bending processing on the upper mounting plate 1.

[0024] The unloading assembly includes a horizontally arranged fixing plate 10, with the side end of the fixing plate 10 fixed to the side end of the base plate 4. A second electric push rod 11 is horizontally fixed to the top of the fixing plate 10. A second connecting plate 12 is fixed to the output of the second electric push rod 11. A movable base 13 is fixed to the side end of the second connecting plate 12. A forming mold 14 is fixed to the top of the movable base 13. The bending head 9 is located directly above the forming mold 14. Specifically, when the second electric push rod 11 is running, it can drive the movable base 13 and the forming mold 14 to move horizontally and linearly back and forth through the second connecting plate 13, thereby facilitating the removal of the upper mounting plate 1 after bending.

[0025] The unloading assembly also includes an opening slot 15, which is opened on the movable base 13 and located inside the forming mold 14. A third electric push rod 16 is vertically fixed at the bottom of the inner wall of the opening slot 15. A lifting plate 17 is fixed at the top of the output shaft of the third electric push rod 16. Specifically, when the third electric push rod 16 is running, it can drive the lifting plate 17 to move up and down, so as to conveniently push the stamped upper mounting plate 1 out of the forming mold 14 for automatic unloading.

[0026] The positioning assembly includes two vertically arranged positioning columns 18 and a shaped column 19. The bottom ends of the two positioning columns 18 and the bottom ends of the shaped column 19 are fixed to the top of the lifting plate 17. The two positioning columns 18 are correspondingly arranged with two positioning holes 2, and the shaped column 19 is correspondingly arranged with the shaped hole 3. Specifically, when the operator places the upper mounting plate 1, he can align the two positioning columns 18 and the shaped column 19 on the upper mounting plate 1 with the two positioning columns 18 and the shaped column 19 on the lifting plate 17 to achieve the function of quick positioning and placement. Under the multiple positioning action of the positioning columns 18 and the shaped column 19, the force displacement of the upper mounting plate 1 during the stamping and bending process can be effectively prevented, which is beneficial to the bending quality of the upper mounting plate 1.

[0027] The positioning assembly also includes two positioning slots 20 and a shaped slot 21. Both positioning slots 20 and shaped slots 21 are vertically opened at the bottom of the bending head 9. Two positioning posts 18 can be inserted into the two positioning slots 20, and shaped posts 19 can be inserted into the shaped slots 21. Specifically, under the action of the positioning slots 20 and shaped slots 21, they can be used to accommodate the positioning posts 18 and shaped posts 19, so that the bending head 9 can move down smoothly.

[0028] It should be noted that the device is electrically connected to an external controller and 220V AC mains power. The controller can be an existing technology device such as a computer. In this application, the precise control principle of the first electric actuator 7, the second electric actuator 11, and the third electric actuator 16 is to achieve motion conversion through the mechanical cooperation of a servo motor and a lead screw. The status is monitored in real time with the help of devices such as encoders, and finally the controller dynamically adjusts the output according to the deviation, thereby achieving precise control of position, speed, and force within the millimeter or even micrometer range.

[0029] The usage process of this utility model is as follows: When using it, the operator first places the upper mounting plate 1 on the top of the forming mold 14. When placing the upper mounting plate 1, the operator can align the two positioning posts 18 and the irregular posts 19 on the upper mounting plate 1 with the two positioning posts 18 and the irregular posts 19 on the lifting plate 17 to achieve the function of quick positioning and placement.

[0030] Then the first electric push rod 7 runs. When the first electric push rod 7 runs, it can drive the bending head 9 to rise and fall through the first connecting plate 8, so that the upper mounting plate 1 can be stamped and bent. Under the action of the positioning groove 20 and the irregular groove 21, it can be used to accommodate the positioning column 18 and the irregular column 19, so that the bending head 9 can move down smoothly. Moreover, under the multiple positioning action of the positioning column 18 and the irregular column 19, it can effectively prevent the upper mounting plate 1 from shifting under force during the stamping and bending process, which is beneficial to the bending quality of the upper mounting plate 1.

[0031] After the mounting plate 1 is bent and formed, the bending head 9 moves back to its original position. Then the second electric push rod 11 runs, controlling the moving base 13 to move laterally, so that the bending head 9 will not affect the unloading of the upper mounting plate 1. Then the third electric push rod 16 runs. When the third electric push rod 16 runs, it can drive the lifting plate 17 to move up and down, so that the stamped upper mounting plate 1 can be easily ejected from the forming mold 14 for automatic unloading.

[0032] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
