Description

Technical Field

[0001] The invention relates to the field of die-casting punching processing, and in particular to a multi-position synchronous punching device in three-dimensional space. Background Art

[0002] Some cast parts require multiple coplanar, tiny holes at different locations on their surfaces. Casting these tiny holes through inserts during casting will greatly increase mold costs and make the casting quality uncontrollable. Therefore, it is generally practiced to drill holes on the surface of the casting after casting is completed.

[0003] When the positions and angles of holes on a casting vary, two processing steps are usually required. The first is vertical drilling, which can be completed in one go using multiple machines. The second is inclined drilling, which requires multiple steps if there are multiple holes. This requires multiple steps and is time-consuming. Summary of the Invention

[0133] A transfer tube 96 is used to transmit force to the punching rotor 542 in a direction parallel to the axis, allowing the drilling direction to be controlled during the drilling process. The transfer tube 96 can be made of a high-pressure resistant material that is inelastically indeformable in the axial and radial directions, such as a high-pressure water pipe. The transfer tube 96 can be bent at any angle to meet the connection requirements of the adjusted position change.

[0134] The multi-position synchronous punching device in three-dimensional space of this embodiment is used as follows: first, the frame is mounted on the telescopic end of the hydraulic cylinder 100 so that the device is suspended in the air.

[0135] Secondly, adjust the position of the vertical punching mechanism and the inclined punching mechanism according to the product that needs to be punched. Specifically, loosen the fixing screw 32 and the adjusting screw 33, slide and adjust the depth position and rotation angle of the adjusting member 31 on the mounting ring 2 so that the vertical punching member 43 is facing the area where vertical punching is required, and then tighten the fixing screw 32 and the adjusting screw 33 to fix the adjusting member 31. Similarly, for the inclined punching mechanism, after adjusting the position of the adjusting member 31, loosen the screws between the first adjusting plate 511 and the second adjusting plate 512, rotate the second adjusting plate, and fix the first adjusting plate 511 and the second adjusting plate 512 after it is rotated into place. Then loosen the screws between the support plate 521 and the insert plate 5221, rotate the plug-in 522, and after the plug-in 522 is rotated to the predetermined angle, fix the support plate 521 and the insert plate 5221. This completes the setting of the inclined punching mechanism.

[0136] Next, select an appropriate adjustment column 98 based on the desired drilling depth of the tilt drilling device and place it into the receiving tube 97. Then, connect and secure the transfer tube 96 to the jacking tube 95 and the receiving tube 97. Finally, place a lubricated jacking ball 99 into the jacking tube 95. Then, select and install the appropriate universal joint and slider coupling based on the drilling depth and transmission requirements.

[0137] During use, the processed component is placed directly below the mounting ring 2, and the hydraulic cylinder 100 is controlled to be lowered, so that the vertical punching member 43 makes vertical holes on the component surface. At the same time, the inclined punching mechanism also descends. When the vertical punching is completed, the pushing cylinder 91 is controlled to extend, forcing the pushing column 93 to squeeze the pushing ball 99 downward, so that the pushing ball 99 moves downward, pushing the adjusting column 98 downward, and finally driving the top plate 544 to slide along the axis of the second fixed tube 53, thereby moving the punching rotary head 542 toward the component surface.

[0138] After the inclined punching is completed, the pushing cylinder 91 is reset, and at the same time, under the action of the reset spring 543, the punching head 542 is also retracted and reset. When the punching head 542 completes the retraction and reset, the hydraulic cylinder 100 is controlled to shorten and complete the separation from the vertical punching member 43 and the components.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
