Description
Technical Field
[0001] The utility model relates to the technical field of automobile production, and particularly relates to a punching device for producing automobile bumpers. Background Art
[0002] Automobile bumpers are installed at the front and rear ends of an automobile. They not only have a decorative function but also can absorb and mitigate external impact forces and protect the vehicle body and the safety of passengers. In the prior art, during the production process of automobile bumpers, it is necessary to process openings at predetermined positions on the automobile bumpers according to process requirements for fixing a tow hook cover or an automobile radar. In the prior art, pneumatic punching or oil cylinder punching is usually adopted, and automated operation can be achieved. Among them, pneumatic punching has the advantages of fast production speed, high efficiency, and variable punching sizes. Oil cylinder punching has the advantage of stable production and can punch products with relatively thick thicknesses. However, these two punching methods also have some deficiencies: (1) When pneumatic punching and oil cylinder punching are used, the air compressor and the hydraulic press are in a continuous running state, resulting in waste of energy. (2) After different-structured automobile products come out, in order to improve production efficiency, it is necessary to use different workstations to produce different products simultaneously. However, the existing pneumatic punching devices and hydraulic punching devices on the market are usually fixed in one place and cannot be moved at any time or moved in a short time, resulting in poor production flexibility. (3) The overall volume of pneumatic punching devices and hydraulic punching devices is relatively large, the cost is relatively high, and they are restricted by the structure of the punching device, so that multiple punching devices at different angles cannot be arranged on one device at the same time. When there are multiple holes at different angles on an automobile bumper, punching at different angles needs to be carried out in several processes, resulting in high labor costs and a long production cycle for products. Summary of the Utility Model
[0003] The present application provides a punching device for producing automobile bumpers to overcome the above problems existing in the prior art. The punching device for producing automobile bumpers in the present application uses a drill bit device for punching operations, which has a relatively low cost, is beneficial to energy saving, and the structure of a single drill bit device is relatively small, so that multiple drill bit devices can be distributed at different positions of the punching device according to needs to achieve simultaneous punching operations at multiple different angles, reducing the number of processes, having high punching efficiency, being beneficial to reducing labor costs and shortening the production cycle of products. Moreover, a moving frame and a clamping pliers are provided in the punching device, which can transport the automobile bumper to be processed to a designated punching position and clamp and limit it, improving the stability during bumper punching, ensuring punching accuracy, and improving product quality. In addition, the punching device in the present application can also be moved according to production requirements to change production workstations, with high usability.
[0004] The technical solution of the present application is as follows:
[0005] The punching equipment for automobile bumper production includes a frame, as well as a mounting frame and a moving frame arranged above the frame; the mounting frame is fixedly connected to the frame; the moving frame is slidably connected to the frame; a set of drill bits is arranged above the moving frame for punching the bumper to be processed; the drill bits are connected to a guide rod and can move up and down relative to the guide rod; the guide rod is fixed on the mounting frame; a set of support blocks is arranged on the moving frame for supporting the bumper to be processed during the punching operation; on the mounting frame, near each drill bit, a pressing clamp is arranged for pressing the bumper to be processed during the punching operation.
[0006] Compared with the prior art, the punching equipment for automobile bumper production in this application uses drill bits for punching operations, with lower costs (only half of the cost of pneumatic punching), which is conducive to saving energy consumption (the drill bits do not need to be in operation all the time during use and can be started or stopped as needed). Moreover, the structure of a single drill bit is relatively small, enabling multiple drill bits to be distributed at different positions of the punching equipment according to needs, thereby achieving simultaneous punching operations at multiple different angles, reducing the number of processes, having high punching efficiency, being conducive to reducing labor costs, and shortening the production cycle of products; in addition, a moving frame is provided on the punching equipment in this application, which can transport the automobile bumper to be processed to the designated punching position, making the preparation operation before punching more labor-saving. Support blocks are arranged on the moving frame to support the bumper, and pressing clamps are also arranged at the working positions corresponding to each punching position to press and limit the bumper, so as to achieve precise positioning of the bumper, ensure the position accuracy of the bumper, prevent the automobile bumper from shaking and being unstable during punching, improve the stability during bumper punching, ensure the punching accuracy, and improve the product quality; moreover, the above specific structure enables the development cycle of the entire punching equipment to be shortened by more than one-third (the development cycle of the punching equipment in this application is expected to be about 30 - 40 days, while the development of hydraulic and pneumatic punching equipment requires about 50 - 60 days).
[0007] As an optimization, in the aforementioned punching equipment for automobile bumper production, slide rails are arranged on both sides of the top of the frame. Correspondingly, sliders are arranged on both sides of the bottom of the moving frame; the sliders are slidably arranged on the slide rails. The arrangement of the slide rails and sliders can limit the moving frame and prevent its position from shifting during movement.
[0008] Further, on both sides of the top of the frame, two positioning blocks are respectively arranged at intervals; positioning holes are formed in the positioning blocks. Correspondingly, one positioning pin is arranged on each side of the moving frame; the positioning pin and the positioning hole cooperate with each other to limit the moving frame. In the initial state, the moving frame is located on the outside, which is convenient for the staff to place the bumper to be processed on the moving frame. At this time, the positioning pin is inserted into the positioning hole on the outside to limit the position, so as to prevent the moving frame from falling outward under the action of external force; when punching operation is required, the moving frame moves inward to the punching position, and then the positioning pin is inserted into the positioning hole on the inside to limit the position, so as to prevent the position of the moving frame from shifting during punching.
[0009] As an optimization, in the punching equipment for automobile bumper production described above, a caster with a brake is respectively arranged at each of the four corners of the bottom of the frame. Through the setting of the casters, it is convenient to move the punching equipment, so that the production station of the punching equipment can be changed according to the production requirements, improving the convenience during use. Further, at each of the four corners of the bottom of the frame, a support foot is respectively arranged beside each caster. After the punching equipment is moved to the designated location, the support feet can be made to contact the ground to support the punching equipment and prevent it from moving during use.
[0010] As an optimization, in the punching equipment for automobile bumper production described above, a moving block is arranged on the drill bit device, a guiding block is arranged on the guiding rod, and a rotating shaft is arranged on the guiding block; the rotating shaft is in transmission connection with the moving block and is used to drive the moving block to move, thereby driving the drill bit device to move up and down. At this time, the structure is simple, the assembly is convenient, and it is easy to implement.
[0011] As an optimization, in the punching equipment for automobile bumper production described above, the frame, the mounting frame and the moving frame are respectively assembled by multiple square tubes. Thus, under the condition of ensuring the bearing capacity of the frame, the mounting frame and the moving frame, their weights can be reduced, making the overall weight of the punching device lighter and saving the material cost.
[0012] As an optimization, in the punching equipment for automobile bumper production described above, the moving frame is of a double-layer structure, and the length of the upper layer is shorter than that of the lower layer; the supporting blocks are distributed at both ends of the upper layer and both ends of the lower layer. Thus, when the bumper is placed on the supporting blocks, it is not easy to tilt.
[0013] The vehicle has a front bumper and a rear bumper. For different bumpers, the structure of the punching device in this application is also different. Among them, in the punching device for the vehicle front bumper, 6 drill bits are arranged at intervals on the mounting frame, and a clamping pliers is arranged on each side of each drill bit; two support blocks are arranged at both ends of the upper layer and the lower layer of the moving frame respectively. In the punching device for the vehicle rear bumper, 6 drill bits are arranged at intervals on the mounting frame; for the two drill bits in the middle, a clamping pliers is arranged on one side of each drill bit respectively, and a clamping pliers is arranged on each side of the remaining drill bits; three support blocks are arranged at both ends of the upper layer of the moving frame respectively, and two support blocks are arranged at both ends of the lower layer of the moving frame respectively.
