Description

Technical Field

[0001] This utility model relates to the field of stamping machines, and in particular to a multi-purpose automatic stamping machine. Background Technology

[0002] Stamping presses are core equipment widely used in metal processing, automobile manufacturing, electronic equipment and other fields. They apply pressure to sheet metal through molds to achieve processes such as punching, forming and stretching. Traditional stamping presses are mostly single-function designs and can only be used to process workpieces of specific shapes or sizes, resulting in low equipment utilization, long mold change time and difficulty in adapting to the flexible production needs of multiple varieties and small batches. Therefore, a multi-purpose automatic stamping press is proposed.

[0003] While most existing automatic stamping machines can replace stamping dies, the process of replacing dies is relatively long and the structure is complex. In addition, before stamping components, it is necessary to visually inspect the stamping die to ensure that there are no foreign objects inside the stamping die, so as to prevent foreign objects from splashing out or affecting the stamping shape during the stamping process. However, due to the obstruction of the equipment at the top, it may be impossible for the operator to clearly observe every position of the stamping die.

[0004] Therefore, in order to solve the problems existing in the above-mentioned technologies, a multi-purpose automatic stamping machine is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-purpose automatic stamping machine. Through the installation of an illumination component, a rotating turntable drives a lead screw, which in turn moves a slider, which in turn moves an illumination lamp. The angle of the illumination lamp can be adjusted by manually turning the metal shaping cartilage, allowing the lamp to illuminate different positions of the lower mold for visual inspection. This avoids injuries to workers caused by foreign objects being ejected during stamping due to poor lighting.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-purpose automatic stamping machine includes a base. Connecting grooves are formed on both sides of the center of the upper surface of the base. A connecting assembly is disposed inside the connecting groove. The connecting assembly includes two sliding rods at the front and rear ends inside the connecting groove. A damping spring is fitted at one end of each sliding rod, and a movable block is fitted at the other end of each sliding rod. A positioning block is fixedly connected to the outer wall of each movable block near the center of the base. A connecting rod is fixedly connected to the outer wall of each movable block near each other. A pull rod is fixedly connected to the outer wall of each connecting rod away from the center of the base, and a force-bearing plate is fixedly connected to the outer wall of each pull rod away from the connecting rod.

[0008] The base has a top plate at its upper end, and a lighting component is provided on one outer wall of the top plate. A movable groove is formed on one outer wall of the lighting component, and a lead screw is rotatably connected to the inner wall of the rear end of the movable groove. A slider is threaded onto the body of the lead screw, and a metal shaping hose is fixedly connected to one outer wall of the slider. A lighting lamp is fixedly connected to one end of the metal shaping hose. A mold assembly is provided at the lower end of the top plate. The mold assembly includes an upper template. A clamping block and a pin block are respectively provided at the center of the upper surface of the upper template. An upper mold is fixedly connected to the lower surface of the upper template. A lower mold is provided at the upper end of the middle part of the base.

[0009] The above technical solution uses a lead screw to drive a slider to adjust the horizontal position of the lighting lamp. Combined with the free bending characteristics of the metal shaping hose, it can accurately illuminate the mold processing area, solving the problem of blind spots in traditional fixed lighting. It is especially suitable for the fine operation of deep cavity molds or small workpieces.

[0010] Furthermore, a mold groove is provided at the center of the upper surface of the base, the lower mold is placed inside the mold groove, and positioning slots are provided at the front and rear ends of the outer walls on both sides of the lower mold, and the positioning blocks are engaged with the positioning slots.

[0011] By using the above technical solution, the lower mold is placed inside the mold slot and then engaged by the positioning block and positioning slot, which enables the lower mold to be quickly installed and disassembled, and also effectively prevents the lower mold from moving during stamping.

[0012] Furthermore, the front and rear ends of the connecting groove near the center of the base are provided with fixing grooves, and the movable blocks slide inside the fixing grooves.

[0013] The above technical solution can effectively limit the movement of the active block and prevent it from moving out of its designated area.

[0014] Furthermore, a retrieval groove is provided in the middle of the outer wall of the rear end of the mold groove, and a mold handle is fixedly connected to the middle of the outer wall of the rear end of the lower mold, and the mold handle is placed inside the retrieval groove.

[0015] The above technical solution allows for easier movement of the mold via the mold handle, and the retrieval slot facilitates storage when placing the lower mold.

[0016] Furthermore, each of the four corners of the upper surface of the base is fixedly connected to a column, and each of the four corners of the lower surface of the top plate is fixedly connected to the upper surface of the column. A cylinder is fixedly connected to the center of the upper surface of the top plate, and the output end of the cylinder is fixedly connected to a pin block. The pin block and the clamping block are fixedly connected by a fixing bolt.

[0017] The above technical solution allows for easier connection between the cylinder and the upper mold plate using the provided pins and clamps, thereby enabling rapid installation and disassembly of the upper mold.

[0018] Furthermore, each of the four corners of the upper surface of the upper template is fixedly connected with a connecting threaded bolt, and the outer wall of each connecting threaded bolt is threaded with a guide rod. The rod body of each guide rod slides inside the top plate, and the upper surface of each guide rod is threaded with a limit plate.

[0019] The above technical solution allows for easier disassembly of the upper mold. Furthermore, during use, the guide rod and limiting plate can guide the upper mold and prevent it from falling.

[0020] Furthermore, a control mechanism is fixedly connected to the upper end of the front outer wall of the base, and cabinet doors are hinged to both sides of the front outer wall of the base.

[0021] The above technical solution allows for better control of the stamping machine through a set control mechanism, and the cabinet doors allow for more effective concealment and placement of items.

[0022] Furthermore, the front end of the lead screw passes through the movable slot to the front end of the movable frame and is fixedly connected to a turntable;

[0023] The above technical solution allows the lead screw to rotate more conveniently via the turntable.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a multi-purpose automatic stamping machine. Through a set connecting component, the pull rod is moved by pulling the force plate, thereby causing the pull rod to drive two movable blocks to move through the connecting rod. This causes the movable blocks to drive the positioning block to slide in the sliding rod body, thereby moving the positioning block out of the positioning slot. This allows for quick replacement of the lower die. Then, by lowering the upper die and separating the pin block from the clamping block by the fixing bolt, the upper die can be quickly replaced. This achieves the purpose of quick die replacement, allowing the stamping machine to be equipped with different stamping dies, enabling it to stamp various components and achieve a multi-purpose purpose.

[0026] 2. The multi-purpose automatic stamping machine proposed in this utility model has an illumination component. By rotating the turntable, the turntable drives the lead screw to rotate, which in turn moves the slider. The slider then moves the illumination lamp. The angle of the illumination lamp can be adjusted by manually turning the metal shaping cartilage, so that the light of the illumination lamp can illuminate different positions of the lower mold for visual inspection. This avoids the injury to the workers caused by the splashing of foreign objects during stamping due to lighting problems. Attached Figure Description

The angle of the lighting lamp 602 can then be adjusted by manually turning the metal shaping hose 603, allowing the lamp to illuminate different positions on the lower mold 907 for visual inspection. Once visual inspection confirms that there are no foreign objects inside the lower mold 907 and the upper mold 901, the component plate to be stamped is placed on the upper end of the lower mold 907. Then, the cylinder 8 is activated, causing the upper template 906 to move. This, in turn, moves the upper mold 901, coordinating with the lower mold 907 to press the component plate. When stamping is in progress and a stamping die needs to be replaced, the upper die 901 is lowered so that it fits against the lower die 907. Then, the pin block 904 is separated from the clamping block 905 by the fixing bolt and the pin shaft, thus quickly disassembling the upper die 901. Then, by pulling the force plate 507, the force plate 507 drives the pull rod 506 to move, which in turn drives the two movable blocks 505 to move through the connecting rod 503. This causes the movable blocks 505 to drive the positioning block 504 to slide on the slide rod 501, thus removing the positioning block 504 from the positioning slot 508. Finally, the upper die 901 and the lower die 907 are removed from the die slot 11 by the die handle 14 for replacement.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
