Description

Technical Field

[0001] The present application relates to the technical field of hot stamping, and in particular to a hot forming steel stamping device. Background Art

[0002] Hot stamping is a part processing method that first heats the blank to a certain temperature, then uses a stamping machine to stamp it in the corresponding mold and quench it under pressure to obtain the desired shape and simultaneously achieve a phase change of the metal material.

[0003] An existing patent (publication number: CN220479975U) discloses a hot forming stamping device comprising a steel rod conveyor line; a stamping mechanism disposed at the end of the steel rod conveyor line, and a heating chamber disposed on the steel rod conveyor line; the stamping mechanism comprises a lower die base; fixed seats disposed on both sides of the lower die base; a quenching chamber formed between the fixed seats; the lower die base disposed between the fixed seats; a guide rod disposed inside the fixed seats; and a transmission member disposed on the guide rod. By providing a heating chamber on the steel rod conveyor line, the steel plate can be kept at a high temperature during the conveying process. The steel plate enters the surface of the lower die base through an inlet. The lower die base is moved upward by a lifting drive mechanism to the fixed seat surface. As the upper die base descends, the punch head extrudes the steel plate on the surface of the lower die base. Because the steel plate can maintain a high temperature during the conveying process, the uniformity of the martensite structure distribution after random forming is guaranteed.

[0004] During use, the above-mentioned document only dissipates heat by using heat fins, and its heat dissipation capacity is limited. At the same time, when the workpiece is stamped, the workpiece will deform and easily adhere to the punch to cause material jamming, thereby affecting the stamping work of the workpiece. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a hot-formed steel stamping device with advantages such as anti-sticking parts and improved cooling efficiency, which solves the problems raised in the background technology.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a hot-forming steel stamping device, comprising a body, a lower die being installed on the inner bottom wall of the body, a first cavity being opened inside the lower die, a first sliding member being slidably connected to the interior of the first cavity, a top plate being fixedly connected to the upper surface of the first sliding member, a plurality of first springs being fixedly connected to the bottom surfaces of the first sliding members, and the other ends of the plurality of first springs being fixedly connected to the first cavity, a punch being provided inside the body, a second cavity being opened inside the punch, a push block being slidably connected to the interior of the second cavity, a plurality of second springs being fixedly connected to the upper surface of the push block, and the other ends of the plurality of second springs being fixedly connected to the second cavity, heat exchange tubes being installed inside the lower die and the punch, and a plurality of heat conducting plates being installed on the outer surfaces of the two heat exchange tubes.

[0007] Through the above solution, the cooperation between the installation top plate, the first sliding member and the first spring can automatically eject the workpiece after processing is completed, thereby preventing the workpiece from being retained in the lower die.

[0008] Furthermore, two fixed cylinders are installed on the upper surface of the lower mold, the heat exchange tube located below is fixedly connected to the two fixed cylinders, the interiors of the two fixed cylinders are slidably connected with extension tubes, the upper ends of the two extension tubes are fixedly connected to the punch, the heat exchange tube located above is fixedly connected to the two extension tubes, and the fixed cylinder located at the front end below is fixedly connected to the output end of the external water pump through a pipeline.

[0009] Through the above solution, the cooperation of the installation extension tube and the fixed tube can always keep the water flow during the process of rising or falling from the head, so that it can cool the punch head and improve the overall practicality.

[0010] Furthermore, two limiting rods are fixedly connected to the upper surface of the lower die, and the punch is slidably plugged into the two limiting rods.

[0011] Through the above solution, installing the limit rod can limit the punch so that the punch can slide vertically stably.

[0012] Furthermore, a soundproof cover is fixedly connected to the upper surface of the machine body, a hydraulic rod is installed on the inner top wall of the soundproof cover, and an output end of the hydraulic rod is fixedly connected to the punch.

[0013] Through the above solution, installing a soundproof cover can reduce the transmission of noise and improve the sound insulation of the body.

[0014] Furthermore, two gratings are installed on the outer surface of the soundproof cover.

[0015] Through the above solution, installing the grating can improve the protection of the machine body and avoid damage to the staff during the work process.

[0016] Furthermore, two insertion holes are provided on the upper surface of the lower die, and both of the insertion holes are connected to the first cavity. Two insertion rods are fixedly connected to the bottom surface of the punch, and both of the insertion rods are adapted to the adjacent insertion holes.

[0017] Through the above solution, the cooperation between the insertion rod and the insertion hole can enable the top plate to maintain a horizontal state with the lower die after the punch and the lower die are overlapped.

[0018] Furthermore, two shock-absorbing pads are fixedly connected to the bottom surface of the body, and the two shock-absorbing pads are symmetrical.

[0019] Through the above solution, installing the shock-absorbing pad can reduce the vibration generated by the machine body during operation and reduce the impact on the surrounding working environment.

[0020] Furthermore, the top plate remains level with the upper surface of the lower mold after being reset.

[0021] Through the above solution, the top plate remains horizontal with the lower die after being reset, which can facilitate the stamping of the workpiece and avoid affecting the stamping work.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0023] This hot-formed steel stamping device, by installing a top plate, the cooperation of a first sliding member and a first spring, can automatically eject the workpiece after processing is completed, thereby preventing the workpiece from being retained in the lower die; and by installing a push block and cooperating with a second spring, the push block can be ejected after processing is completed, thereby preventing the workpiece from adhering to the punch and affecting the next stamping work; and by installing a heat exchange tube and cooperating with multiple heat conducting plates, the cooling efficiency of the lower die and the punch can be improved, thereby improving the overall practicality.
