Description

Technical Field

[0001] The utility model relates to the technical field of automobile sheet metal, in particular to a rapid prototyping die for automobile sheet metal parts. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm thick), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as car bodies), etc. Its most notable feature is that the thickness of the same part is consistent. Products processed by the sheet metal industry are called sheet metal parts. Stamping dies are special process equipment that processes materials (metal or non-metal) into parts (or semi-finished products) in cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause it to separate or plastically deform, thereby obtaining the desired parts.

[0003] According to the search, the Chinese patent document, announcement number: CN 211758041 U, discloses a rapid prototyping mold for automobile sheet metal parts. The synchronous output of the hydraulic cylinder makes the upper die seat move downward, and then the punch rod punches the sheet metal parts in the lower die seat, so that the sheet metal parts are quickly punched and formed. The waste material punched by the punch rod enters the drawer through the discharge hole. The setting of the inclined plate allows the waste material to fall into the through hole. The through hole is opened by pulling the plug plate, and the punched waste material on the inclined plate in the drawer is discharged from the through hole, which is convenient for collecting and cleaning the punched waste material. The operation is simple, avoiding direct discharge to the outside to pollute the working environment. The collected waste material can be discharged into a garbage bag or a storage box through the through hole for recycling. The device pulls the plug plate to discharge the waste material in the drawer, and then closes it by plugging it back, which undoubtedly adds some trouble. At the same time, the iron filings and dust generated by the punching may stick to the inner wall of the drawer and cannot come down, which is difficult to handle. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a rapid prototyping mold for automobile sheet metal parts, which has the function of allowing waste materials from sheet metal stamping to fall into a collection box by pulling a baffle, and blowing iron filings, dust and the like generated by stamping to a dust exhaust pipe for unified treatment by starting a fan, thereby cleaning the inside of the collection box, thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rapid prototyping mold for automobile sheet metal parts, comprising a workbench, wherein side panels are symmetrically arranged on the upper end of the workbench, a fixed plate is fixedly connected to the upper end of the side panel, a hydraulic cylinder is arranged at the lower end of the fixed plate, a punching rod is arranged at the lower end of the hydraulic cylinder, a lower die seat is arranged at the lower end of the punching rod, a collecting box is arranged at the lower end of the workbench, and a discharge pipe is opened at the lower end of the collecting box.

[0009] Through the above technical solution, by starting the hydraulic cylinder, the hydraulic cylinder drives its punching rod to feed downward, and then the punching rod punches the sheet metal part in the lower die seat, so that the sheet metal part is quickly stamped and formed. After the punching rod completes the stamping, the waste material falls into the collection box through the through hole due to gravity.

[0010] Preferably, a first slot is formed through the upper surface of the collection box, the first slot is located directly below the through hole, the first slot is equal to the through hole opening in size and shape, and the upper end of the outer edge of the first slot is fixedly connected to a panel, and the upper end of the panel is fixedly connected to the workbench.

[0011] Through the above technical scheme, a surround is fixedly connected to the gap between the workbench and the collection box, and the workbench and the collection box are connected by the surround, and a first slot is opened on the inner wall of the surround. The first slot is located directly below the through hole and is equal to the size and shape of the through hole.

[0017] Through the above technical solution, after the waste material collected inside the collection box is full, by putting a plastic bag on the outer wall of the dust exhaust pipe and starting the fan, the fan will push the air valve cover, that is, generate wind force, so that the back of the air valve cover can be pushed, so that the air valve cover is opened and the second spring is stretched and stressed by the air valve cover, and the fine particles of dust generated by the waste material can be blown to the discharge port, so that the inside of the collection box can be cleaned. When the fan stops, due to the action of the second spring, the second spring can drive the air valve cover back to its position, so that the collection box can be closed and sealed, ensuring that no metal filings will escape from the collection box, and large sheet metal waste materials can be discharged through the discharge pipe at the lower end.

[0018] Compared with the prior art, the utility model provides a rapid prototyping die for automobile sheet metal parts, which has the following beneficial effects:

[0019] 1. The utility model provides a baffle plate, a first spring and other components. When the waste material is punched by the punching rod, it falls to the upper end of the baffle plate through the through hole due to gravity. By pulling the baffle plate outward, the baffle plate is pulled out of the enclosure plate, that is, the waste material falls into the collection box due to gravity. At this time, the first springs on both sides of the enclosure plate are in a stretched stress state. When the force applied to the baffle plate is released, the first spring acts to drive the convex block to guide the baffle plate to be inserted back into the enclosure plate, thereby sealing the interior of the collection box to prevent the waste material from leaking out.

[0020] 2. The utility model provides a fan and an air valve cover and other components. After the waste materials collected in the collection box are full, a plastic bag is put on the outer wall of the dust exhaust pipe and the fan is started. The fan will push the air valve cover, that is, generate wind force, thereby pushing the back of the air valve cover, so that the air valve cover is opened and the second spring is stretched and stressed by the air valve cover, and fine particles of dust generated by the waste materials are blown to the discharge port, thereby cleaning the inside of the collection box. When the fan stops, due to the action of the second spring, the second spring can drive the air valve cover back to its position, thereby closing and sealing the collection box to ensure that no metal filings escape from the collection box, and large sheet metal waste materials can be discharged through the discharge pipe at the lower end.
