Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a mounting support punching device for a load-bearing frame. Background Art

[0002] The load-bearing frame is called an integrated frame or a monocoque frame. It is a commonly used structural technology in modern automobile design. The mounting bracket is an important structure on the frame for connecting and supporting other components. The mounting bracket needs to be punched to facilitate installation. When the punching device is in use, most of the residual material punched out will be blocked in the through-hole inside the punching seat, resulting in the inability to discharge the subsequent residual material, resulting in different subsequent punching quality and the need for frequent cleaning, which is very troublesome. Utility Model Content

[0003] The purpose of the present invention is to provide a mounting support punching device for a load-bearing frame, so as to solve the problem in the background art that during punching, the material remains inside the punching seat and cannot be discharged, thereby affecting the quality of subsequent punching.

[0006] By adopting the above technical solution, after punching through the punching seat and the punching head, the punched-out material will remain inside the through hole of the punching seat. At the same time, the soft sleeve will fit with the outer surface of the mounting support, and at the same time cooperate with the vent pipe to deliver high-pressure gas, so that the high-pressure gas will blow out the remaining material in the punching seat, so that the punched-out remaining material will not be blocked inside the punching seat, and there is no need to clean it from time to time.

[0007] Preferably, a mounting support is placed on the outer surface of the stamping seat, and a through hole is provided on the outer surface of the stamping seat. A through hole is opened on the outer surface of the bottom fixing frame, and the through hole of the bottom fixing frame is fitted with the through hole of the stamping seat. A material storage box is slidably installed on one end of the bottom fixing frame away from the top fixing frame, and through holes are evenly opened on the outer surface of the material storage box.

[0008] By adopting the above technical solution, after stamping, the high-pressure gas ejected from the vent pipe will blow out the material in the through hole of the stamping seat, causing the material to fall into the interior of the storage box, and the high-pressure gas will be discharged outward from the through hole on the outer surface of the storage box. The punched-out material will be collected through the storage box, so that the remaining material can be processed centrally without affecting the surrounding environmental hygiene.

[0009] Preferably, an identification snap-fit mechanism is provided between the guide sleeves, and the identification snap-fit mechanism enables the parts to run in parallel.

[0010] By adopting the above technical solution, the roller can move in parallel and keep in stable contact with the slider, thereby reducing the probability of deformation of the roller due to tilting operation.

[0011] Preferably, the identification snap-fit mechanism includes: scale lines, the scale lines are arranged on the outer surface of the guide sleeve, and the outer surface of the guide sleeve is provided with a snap-fit groove, the outer surface of the guide sleeve is fixedly installed with a fixed sleeve rod, and the fixed sleeve rod is snap-fitted with the snap-fit groove, the outer surface of the fixed sleeve rod is rotatably installed with a roller, and the roller is located between the guide sleeves.

[0013] Preferably, an elastic sliding mechanism is provided on the outer surface of the bottom fixing frame, and the mounting support is clamped by the elastic sliding mechanism.

[0014] By adopting the above technical solution, the mounting support placed on the outer surface of the punching seat can be clamped and fixed, so that the top fixing frame can clamp the mounting support while descending, reducing the chance of the mounting support jumping up and moving during punching and generating waste.

[0016] With the above technical solution, as the top fixing frame is pressed down, the guide sleeve will be driven to move, so that the roller will fit the outer surface of the slider, driving the slider and the rubber extrusion block to move toward the stamping seat to fix the mounting support. After punching, as the roller rises, the second spring will push the slider back to its original position.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the mounting support punching device for a load-bearing frame:

[0018] 1. As the hydraulic cylinder is pushed out, the top fixing frame will be driven to move, and the top fixing frame will move along the direction of the guide connecting rod, driving the punching head and the soft sleeve to lean against the punching seat, so that the soft sleeve and the outer surface of the mounting support are in contact and punching is performed. When the top fixing frame lifts the punching seat and separates the punching head, the solenoid valve will be activated to release the gas in the air inlet pipe, so that the high-pressure gas is discharged into the interior of the soft sleeve through the vent pipe, and the material punched out in the through hole of the punching seat is blown out, so as to keep the through hole of the punching seat unobstructed, without affecting the subsequent punching, and without the need for cleaning and dredging;

[0019] 2. The graduated grooves on the outer surface of the guide sleeve ensure that the fixing rods on both sides are at the same height when installing, preventing the roller from tilting. Furthermore, the engagement of the fixing rods with the engaging grooves prevents the roller from shifting when pressed down and in contact with the slider, reducing the chance of deformation and breakage caused by tilted use.

[0020] 3. As the top fixing frame is pressed down, the roller will be driven down together, so that the roller will be in contact with the outer surface of the slider, pushing the slider toward the punching seat to clamp and fix the mounting bracket. At the same time, the position of the rubber extrusion block and the position of the fixing sleeve on the guide sleeve can be adjusted to facilitate the clamping and fixing of mounting brackets of different thicknesses and sizes, so that the mounting bracket will not jump or move during punching to produce waste, thereby improving the stability during punching and reducing the chance of operator injury.
