When the centering ring 12 is completely bent, the first pressure lever 53 moves downward, the first inclined surface 531 abuts against the second inclined surface 541 and pushes the transmission block 54 to move towards the punch block 51 and pushes the punch block 51 to move towards the direction close to the stop member 52, and the second groove 511 acts on the bending portion 122, so that the bending portion 122 curls towards the fan blades 11 until the formed middle ring 12 is formed.
Optionally, each stamping module is provided with two groups of completely-bent structures to bend the middle rings 12 of the two fan blades 11 of the same group of casement hinges in the group at the same time, so that the efficiency is improved.
In order to ensure the stability of the second groove 511 acting on the bending portion 122, optionally, the punch transmission structure further includes a cushion block 55, the cushion block 55 is disposed on one side of the punch 51 away from the stop member 52, the cushion block 55 has a larger volume, the area of one side abutting against the punch 51 is larger, and the transmission block 54 acts on the punch 51 through the cushion block 55, so that the stress of the punch 51 can be more uniform, and the bending effect can be improved.
Referring to fig. 11, optionally, the casement hinge stamping device further includes a middle ring squeezing structure 6, wherein the middle ring squeezing structure 6 is used for squeezing the middle ring 12 to increase a gap between the middle rings 12, so that the middle rings 12 of the two blades 11 of the same set of casement hinges can be smoothly placed in a staggered manner, and then the central rotating shaft of the casement hinge is installed. In order to improve the production efficiency, two groups of middle ring extrusion structures are arranged on the first stamping module and the second stamping module respectively to extrude middle rings 12 on two fan blades 11 of the same group of flat-open hinges respectively.
Specifically, the middle ring extrusion structure 6 includes a second pressure lever 61 and a third pressure lever 62 which are opposite and spaced, a third inclined surface 611 is disposed at the bottom end of the second pressure lever 61, a fourth inclined surface 621 is disposed at the bottom end of the third pressure lever 62, and the third inclined surface 611 and the fourth inclined surface 621 are both inclined from top to bottom toward a direction away from each other.
When the flat-open hinge stamping device is closed, the second pressure lever 61 and the third pressure lever 62 move downwards, so that the third inclined surface 611 abuts and presses one end of the middle ring 12, the fourth inclined surface 621 abuts and presses the other end of the middle ring 12, and the same middle ring extrusion structure 6 sequentially extrudes the middle ring 12 on the same fan blade 11, so that the gap between the middle rings 12 is increased, and the symmetry of the middle rings 12 is ensured.
Referring to fig. 3, the flat-open hinge stamping apparatus further includes a first middle ring extrusion station 77 and a second middle ring extrusion station 87, wherein two middle ring extrusion structures 6 are disposed at the first middle ring extrusion station 77 and the second middle ring extrusion station 87 respectively to extrude the middle rings 12 on the two leaves 11 of the two sets of flat-open hinges respectively.
Optionally, the flat-open hinge stamping equipment further comprises a blanking mechanism, and one side of the middle ring extrusion structure 6 is provided with a group of blanking mechanisms so as to transfer the fan blades 11 completing the middle ring 12 extrusion process into the material collecting box. The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
