Description

Technical Field

[0001] The utility model relates to the technical field of stamping, in particular to a stamping machine used for metal manufacturing. Background Art

[0002] Stamping is a process used to create metal parts and products of various shapes and sizes. The operating principle of a metal stamping machine is based on the action of pressure. A motor or other power source drives a slider-crank mechanism, a guide rod mechanism, or a hydraulic system, generating strong pressure. This forces the die to impact the metal sheet, thereby achieving plastic deformation.

[0003] In the process of metal stamping, the mold needs to be fixed on the stamping machine. Traditionally, the mold is fixed by multiple bolts. At the same time, the holes on the mold must correspond to the threaded holes on the stamping machine. If the holes on the mold do not correspond to the threaded holes on the stamping machine, the mold cannot be installed on the stamping equipment. Therefore, a stamping machine for metal manufacturing is proposed. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides a punching machine for metal manufacturing, comprising a bottom plate, wherein sliding rods are fixedly installed at positions near the four corners of the bottom plate, a top plate is fixedly installed at the other ends of the four sliding rods, a punching cylinder is fixedly installed at the center position of the top plate, a working end of the punching cylinder is fixedly connected to a receiving plate, and the receiving plate is slidably installed on the four sliding rods, and a receiving plate and a mold fixing plate are slidably installed on the four sliding rods respectively, an upper mold is provided on the mold fixing plate, a lower mold is provided on the bottom plate, and the upper mold and the lower mold are fixedly installed. A telescopic device is provided in the mold, and the telescopic device includes a bidirectional threaded screw, which is rotatably installed in the upper mold and the lower mold respectively. Two threaded sliders are threaded on the bidirectional threaded screw, and the threaded slider is hinged to two support rods. The other end of the support rod is hinged to the supporting bar, and two fixed components are provided near the two ends of the supporting bar. The fixed component includes a fixed slider, which slides between the upper mold and the lower mold. An L-shaped fixing plate and a screw are hinged on the fixed slider, and a nut is threaded on the screw.

[0006] As a further improvement of the present technical solution, the receiving plate is fixedly connected to the working end of the stamping cylinder, and the stamping cylinder drives the receiving plate, the mold fixing plate and the upper mold to move vertically.

[0007] As a further improvement of the present technical solution, the sliding rod sleeve is provided with a shock-absorbing spring, one end of the shock-absorbing spring is fixedly connected to the bottom side of the receiving plate, and the other end of the shock-absorbing spring is fixedly connected to the top side of the mold fixing plate. The receiving plate and the stamping cylinder are driven by the stamping cylinder to press vertically downward. When the upper mold contacts the lower mold, the shock-absorbing spring buffers the upper mold.

[0008] As a further improvement of the present technical solution, rotating the bidirectional threaded screw drives the two threaded sliders to move toward each other, and at the same time drives the multiple support rods to move, so that the two connecting bars move toward each other.

[0009] As a further improvement of this technical solution, the fixed slider, L-shaped fixing plate, screw and nut are matched so that the L-shaped fixing plate fixes the upper mold and the lower mold on the mold fixing plate and the bottom plate respectively through the screw and nut.

Through the four sliding rods 2, when the stamping cylinder 4 drives the receiving plate 5 and the mold fixing plate 7 to move vertically, the receiving plate 5 and the mold fixing plate 7 can be limited, thereby preventing the receiving plate 5 and the mold fixing plate 7 from being moved vertically. Offset, at the same time, the four sliding rods 2 can also support the top plate 3, an upper mold 9 is provided on the mold fixing plate 7, and a lower mold 8 is provided on the bottom plate 1. The stamping cylinder 4 drives the receiving plate 5, the mold fixing plate 7 and the upper mold 9 to move vertically, and the sliding rod 2 is provided with a shock-absorbing spring 6, one end of the shock-absorbing spring 6 is fixedly connected to the bottom side of the receiving plate 5, and the other end of the shock-absorbing spring 6 is fixedly connected to the top side of the mold fixing plate 7. When the stamping cylinder 4 drives the receiving plate 5 and the stamping cylinder 4 to press vertically downward, when the upper mold 9 contacts the lower mold 8, the shock-absorbing spring 6 buffers the upper mold 9 to avoid damage to the stamping equipment and the mold during the stamping process.

[0025] See also Figure 5 As shown, a telescopic device 10 is provided in the upper mold 9 and the lower mold 8. The telescopic device 10 includes a bidirectional threaded screw 111, which is rotatably installed in the upper mold 9 and the lower mold 8 respectively. One end of the bidirectional threaded screw 111 passes through one side of the upper mold 9 and the lower mold 8, and the bidirectional threaded screw 111 passes through one end of the upper mold 9 and the lower mold 8 and is fixedly installed with a hexagonal block, which is convenient for the staff to drive the bidirectional threaded screw 111 to rotate by rotating the hexagonal block. Two threaded sliders 112 are threadedly installed on the bidirectional threaded screw 111. When the bidirectional threaded screw 111 rotates, the threaded slider 112 is driven to move toward each other on the bidirectional threaded screw 111. The threaded slider 112 is hinged to two support rods 113, and the other end of the support rod 113 is hinged to the supporting bar 11. Rotating the bidirectional threaded screw 111 drives the two threaded sliders 112 to move toward each other, and at the same time drives multiple support rods 113 to move, thereby enabling the two supporting bars 11 to move toward each other.

[0026] See also Figure 6As shown, two fixing components 12 are provided near the two ends of the supporting bar 11, and the fixing component 12 includes a fixing slider 121, and the fixing slider 121 slides between the upper mold 9 and the lower mold 8. The fixing slider 121 is hinged with an L-shaped fixing plate 122 and a screw 123, and the screw 123 is threadedly connected with a nut 124. Through the rotation of the L-shaped fixing plate 122 and the screw 123, the L-shaped fixing plate 122 contacts the bottom plate 1 or the top side of the mold fixing plate 7, and then the nut 124 is rotated to make the L-shaped fixing plate 122 squeeze and fix the bottom plate 1 or the mold fixing plate 7. The cooperation of the fixing slider 121, the L-shaped fixing plate 122, the screw 123 and the nut 124 enables the L-shaped fixing plate 122 to fix the upper mold 9 and the lower mold 8 to the mold fixing plate 7 and the bottom plate 1 respectively through the screw 123 and the nut 124, ensuring that the mold is stably mounted on the stamping equipment.

[0027] When the stamping machine for metal manufacturing of this embodiment is used, first, the stamping equipment is connected to the power supply, and then the upper die 9 and the lower die 8 are installed on the stamping equipment, and the die is adjusted according to the specifications of the stamping equipment. Then, the two threaded sliders 112 are driven to move toward each other by the bidirectional threaded screw 111, and at the same time, multiple support rods 113 are driven to move, so that the two connecting bars 11 move toward each other, and then adjusted according to the mold fixing position of the stamping equipment, and the fixed slider 121 on the connecting bar 11 moves together, so that the threaded slider 112 slides in the mold, and finally, it is adjusted to correspond to the mold fixing position, and then the mold is fixed by the L-shaped fixing plate 122, screw 123 and nut 124 on the threaded slider 112 to ensure that the mold is stably installed on the stamping equipment.
