The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Example one

As shown in fig. 1 to 7, a hydraulic oblique-mouth spinning flanging machine for flanging an oblique end face of a cylindrical workpiece includes:

the flanging mechanism 2 is suitable for extruding the end face of the workpiece to be flanged; the flanging mechanism 2 comprises a pressure plate 201 contacted with the end face to be flanged of the workpiece, the end face normal line of the pressure plate 201 is obliquely arranged with the central axis of the workpiece, and the pressure plate 201 can move in the plane parallel to the end face of the pressure plate 201 and rotate around the fixed central axis in the plane parallel to the end face of the pressure plate 201. That is, the platen 201 can perform both rotational movement and planar movement, and the rotation axis of the rotational movement is perpendicular to the moving direction, and when the platen 201 moves in a plane, the rotation radius of the platen 201 changes, so that the contact area between the platen 201 and the end face of the workpiece changes. Since the inclined end surface of the workpiece is an elliptical end surface, it is necessary to change the radius of gyration of the platen 201 so that the platen 201 can make contact with each point on the end surface of the workpiece.

The clamping mechanism 1 is used for clamping workpieces, the workpieces processed by the invention are cylindrical tubular structures, and the following clamping mechanism 1 can be selected: the device comprises a cylindrical guide support shaft 101 and a base plate, wherein the cylindrical guide support shaft 101 is suitable for sleeving a cylindrical workpiece, a central shaft of the cylindrical guide support shaft 101 is the central shaft of the workpiece, and the cylindrical guide support shaft 101 and the flanging mechanism 2 are positioned on two sides of the base plate. The angle between the cylindrical guide support shaft 101 and the normal of the end surface of the platen 201 is an acute angle. The backing plate has an oval opening 110 for the workpiece to pass through; when the pressing plate 201 presses the workpiece, the flange of the workpiece is attached to the backing plate. As shown in the figure, the diameter of the cylinder guide support shaft 101 is slightly smaller than the inner diameter of the workpiece and is used for supporting the workpiece, the cylinder guide support shaft 101 is located on the left side of the base plate, the flanging mechanism 2 is located on the right side of the base plate, and the end face of the workpiece to be flanged is located at the rightmost end of the cylinder guide support shaft 101 and is right opposite to the pressure plate 201. The backing plate is used for providing a support surface for the workpiece after flanging, the oval opening 110 is slightly larger than the outer diameter of the workpiece, and when the workpiece is extruded by the flanging mechanism 2, the turnover part of the workpiece is positioned between the backing plate and the pressing plate 201.

The turn-up mechanism 2 in the present embodiment includes a rotary shaft 202, a driving motor 203 adapted to drive the rotary shaft 202 to rotate, and a fixed disk 204 fixedly connected to the rotary shaft 202; the rotation axis 202 is arranged parallel to the end surface normal of the platen 201. The fixed disc 204 is fixed with a linear driving mechanism 205, and the pressure disc 201 is connected with one end of the fixed disc 204 in a sliding way and driven by the linear driving mechanism 205 to move linearly in a plane parallel to the end face of the pressure disc 201. The rotating shaft 202 can be erected on a fixed structure, the rotating shaft 202 is driven by the driving motor 203 to rotate, so as to drive the fixed disc 204 to rotate, the fixed disc 204 drives the pressure plate 201 to rotate, and meanwhile, the pressure plate 201 can be driven to move on the fixed disc 204 by the linear driving mechanism 205.

As shown in fig. 7, the rotating shaft 202 is erected in the box 213 and is rotatably connected with the box 213 through a bearing 206, the driving motor 203 is fixed on the top of the box 213, the output end of the driving motor 203 is provided with a driving wheel 207, one end of the rotating shaft 202 extends out of the box 213 and is sleeved with a rotating pulley 208, the driving wheel 207 is in transmission connection with the rotating pulley 208 through a belt, the other end of the rotating shaft 202 extends out of the box 213 and is fixedly connected with the fixed disk 204, the fixed disk 204 is in a hollow roller structure, the linear driving mechanism 205 is fixed inside the fixed disk 204, and the linear driving mechanism 205 can be a hydraulic cylinder. The end face of the fixed disc 204, on which the pressure plate 201 is mounted, is provided with a through hole, the pressure plate 201 is of a disc-shaped structure, the pressure plate 201 is sleeved and fixed on a columnar connecting post 209, and the connecting post 209 penetrates through the through hole on the fixed disc 204 and is connected with the movable end of the linear driving mechanism 205. The through holes on the fixing plate 204 are in a kidney-shaped or rectangular structure, and space is reserved for the connecting posts 209 and the platen 201 to move in a plane. The center of the pressing plate 201 is hollowed, and the pressing plate 201 mainly depends on the end surface of the periphery of the pressing plate to extrude and flange the workpiece.

Preferably, the end of the pad facing the platen 201 has a protruding edge 109 protruding from the end face of the pad, and the protruding edge 109 is disposed along the oval opening 110. When the workpiece is flanged, the flanging part is squeezed between the flange 109 and the platen 201. The ledge 109 may also be separate from the backing plate, for example, the ledge 109 may have a shoulder that fits over the inside of the oval opening 110, so that workpieces of different diameters may be more easily flanged by replacing the ledge 109 with a different size.

Example two

In the first embodiment, when the platen 201 contacts with a workpiece, the platen 201 only rotates along with the rotating shaft 202, and the platen 201 itself does not have a free rotation function, so that the friction force between the platen 201 and the workpiece is large, and the workpiece is easily damaged, secondly, the plane motion of the platen 201 is only controlled by the linear driving mechanism 205, and when the rotating shaft 202 rotates rapidly, the linear driving mechanism 205 also rotates along with the workpiece, and the linear driving mechanism 205 is often difficult to realize stable linear extension and retraction. For this reason, the present embodiment is modified as follows:

the end face of the fixed disc 204 is fixed with a first slide rail 210, the first slide rail 210 is matched with a slide block 211 in a sliding way, the pressure disc 201 is rotationally connected with the slide block 211, and the slide block 211 is connected with the linear driving mechanism 205. As shown in fig. 6 and 7, the slider 211 is composed of a sliding panel 2111 attached to the end surface of the fixed disk 204 and a sleeve 2112 passing through the through hole of the fixed disk 204, the connecting rod 209 is located on the inner periphery of the sleeve 2112 and rotatably connected to the sleeve 2112 through the bearing 206, two sides of the sliding panel 2111 are attached to the first slide rail 210, so that the sliding panel 2111 reciprocates along the first slide rail 210, and the extending direction of the first slide rail 210 is parallel to the extending and retracting direction of the linear driving mechanism 205.

In this embodiment, the linear motion of the platen 201 in the plane may be limited by the first slide rail 210, and the linear driving mechanism 205 is not required to be completely controlled, and the linear driving mechanism 205 only needs to provide the pushing power. In addition, when the pressure plate 201 is extruded on the end face of the workpiece and rotates around the rotating shaft 202, the pressure plate 201 can rotate around the central shaft of the pressure plate 201, and the pressure plate 201 can freely rotate along the direction of the friction force under the action of the friction force, so that the friction force is reduced, and the abrasion of the pressure plate 201 on the workpiece is reduced.

EXAMPLE five

On the basis of the above embodiment, the embodiment increases the tensioning function of the workpiece, and avoids the situation that a hole exists between the cylinder guide support shaft and the workpiece, which causes deformation when the workpiece is turned over, specifically, the cylinder guide support shaft 101 includes a first hydraulic cylinder 107 fixed on the mounting seat 108, a tapered cylinder 111 connected to a piston rod of the first hydraulic cylinder 107, a shaft cylinder 112 sleeved on the periphery of the piston rod of the first hydraulic cylinder 107 and fixed to the mounting seat 108, and a tensioning claw sleeved on the periphery of the tapered cylinder 111 and fixed to the shaft cylinder 112, and the workpiece is suitable for being sleeved on the tensioning claw 113.
