Description

Technical Field

[0001] The utility model relates to the technical field of automobile bumper processing, in particular to a punching machine universal for front and rear bumpers of automobiles. Background Art

[0002] Bumpers are installed at both the front and rear ends of the car. The front and rear bumpers not only have decorative functions, but more importantly, they are safety devices that absorb and mitigate external impact, protect the car body and protect the safety of the passengers. They are one of the important external structural components of the car. During production, punching equipment is required to punch holes inside the front and rear bumpers to facilitate the installation and positioning of the bumpers and the installation of other components.

[0003] The existing bumper punching assembly has the following disadvantages when in use: the existing bumper punching equipment is usually a single die base structure, that is, the internal supporting assembly of the equipment can only install a set of positioning dies and the bumper to be processed. Since the front and rear bumpers of the car have certain differences in specifications and installation positions, when punching the front and rear bumpers, it is necessary to replace different die bases to support the bumpers in different positions. The operation process is cumbersome and complicated. For this reason, we propose a punching machine that is universal for the front and rear bumpers of cars. Utility Model Content

[0007] Furthermore, it also includes a limiting mechanism, a limiting mechanism is arranged between the fixed plate and the swivel, the limiting mechanism includes a spring, a pin and a limiting groove, the surface of the fixed plate away from the swivel is movably connected to the pin through a spring, a limiting groove is provided inside the swivel and the end of the pin is inserted into the limiting groove; in use, the pin is inserted into the limiting groove inside the swivel, and the cooperation between the pin and the limiting groove fixes the angle of the swivel. When the front bumper support and the rear bumper support need to be flipped and adjusted, the swivel can be flipped by pulling the pin outward to pull it out of the limiting hole. After reaching the appropriate position, the limiting groove is aligned with the pin, and the pin can be automatically inserted under the action of the spring to fix the angle of the swivel.

[0008] Furthermore, a slide groove is provided in the horizontal direction at the bottom of the inner wall of the machine body, and a slider located inside the slide groove is installed at the bottom of the bottom plate; through the cooperation of the slide groove and the slider, the bottom plate can drive the fixed plate to move smoothly.

[0009] Furthermore, a cylinder is installed on one side of the body surface, and the power output end of the cylinder extends into the interior of the body and is connected to the surface of the fixed plate; when the cylinder is running, its power end drives the horizontal displacement of the fixed plate.

[0010] Furthermore, a through slot corresponding to the position of the limiting slot is opened horizontally inside the fixing plate, and the latch passes through the through slot; the latch structure passes through the through slot, making it easy to insert into the limiting slot, and the through slot structure can limit the position of the latch.

[0011] Compared with the prior art, the present invention has the following beneficial effects: a swivel structure is provided on the surface of the fixed plate, and a front bumper support and a rear bumper support are respectively provided at the upper and lower ends of the swivel structure. In normal use, the base plate and the fixed plate are located inside the machine body, and the stamping unit uses a punch to punch the bumper on the support surface located at the top of the swivel. When it is necessary to process bumpers in different positions, the base plate is controlled to move out, and then the swivel is rotated, and the appropriate bumper support is adjusted to move to the working position at the top of the swivel. There is no need to replace the supporting component, which is convenient and fast to switch the front and rear bumper processing modes. It is easy to use and meets different production needs. In use, the pin is inserted into the limit groove inside the swivel. The cooperation between the pin and the limit groove plays a fixing role on the swivel angle. When it is necessary to flip and adjust the front bumper support and the rear bumper support, the pin only needs to be pulled out to withdraw it from the limit hole to flip the swivel. After reaching the appropriate position, the limit groove is aligned with the pin, and the pin can be automatically inserted under the action of the spring to fix the swivel angle.
