Detailed Description
The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.
The first embodiment is shown in the attached fig. 1 to fig. 3.
The utility model provides an aviation class bolt punching press is with detachable sleeve, includes sleeve part 1 and flange portion 3, sleeve part 1 and flange portion 3 integrated into one piece. The sleeve portion 1 is provided with a through guide hole 2, and the guide hole 2 extends in the axial direction of the sleeve portion 1. And the workpiece to be machined is placed at the bottom end of the guide hole 2, and the punching head penetrates through the guide hole 2 to complete punching operation on the workpiece to be machined. The flange portion 3 is distributed at the bottom end of the sleeve portion 1 in the axial direction, and the flange portion 3 is connected to a punch through a fastener. The fastener in this embodiment is a bolt, and specifically, the fastener has a shank 5 and a head 6, the diameter of the head 6 is larger than that of the shank 5, the shank 5 is provided with an external thread, and the shank 5 is screwed to a punch. The flange portion 3 is provided with three fixing grooves 7, and the three fixing grooves 7 are distributed in a circumferential array. The fixing groove 7 comprises a large diameter portion 8, a communication portion 9 and a small diameter portion 10 which are communicated with each other, wherein the diameter of the large diameter portion 8 is larger than that of the head portion 6 of the fastener, and the diameter of the small diameter portion 10 is smaller than that of the head portion 6. The sleeve portion 1, the flange portion 3 and the press sleeve are rotatable relative to the fastener to cause the fastener to slide back and forth between the small diameter portion 10 and the large diameter portion 8. Dismantle the utility model provides a during the punching press sleeve, at first unscrew the fastener (need not to make fastener and punching machine drop), then rotatory punching press sleeve makes the fastener change to one side of major diameter portion 8 by one side of minor diameter portion 10, can take off the punching press sleeve from the punching machine.
For the convenience of manual operation, recesses 12 are provided in the side walls of the flange portion 3. Meanwhile, the stepped surfaces 11 are respectively arranged in the communication portion 9 and the small-diameter portion 10, so that the head portion 6 of the fastening member can be completely sunk into the fixing groove 7 without protruding out of the surface of the flange portion 3.
Embodiment two is shown with reference to fig. 4 to 6.
The difference between the present embodiment and the first embodiment is: in the present embodiment, the sleeve portion 1 and the flange portion 3 are detachably connected. Specifically, a flange 13 is provided at the bottom of the sleeve portion 1, and three fixing grooves 7 are provided in the flange 13, the three fixing grooves 7 being arranged in a circumferential array. The flange portion 3 is connected with a fastening piece, and the sleeve portion 1 is fixed to the flange portion 3 through the fastening piece. Specifically, the sleeve portion 1 and the flange portion 3 are disassembled in the same manner as the punch sleeve and the punch press, and thus, the details thereof are not repeated.
The second embodiment is provided to save the cost for manufacturing the stamped sleeve: when the diameter of the punch changes, the punch sleeve needs to be replaced in order to adapt the guide hole 2 to the punch. The punching sleeve has large volume, and more raw materials are consumed during manufacturing; however, the sleeve part 1 is relatively independent and small in size, and only the sleeve part 1 needs to be replaced, so that the consumption of raw materials can be saved while the sleeve part is suitable for machining workpieces of various types.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
