[0015] (1) In the hinge rolling processing device, the user adjusts the distance between the clamping plate and the right end of the sliding threaded sleeve by turning the knob, thereby clamping hinge sheet metals of different thicknesses. The user pushes the sliding threaded sleeve by the push rod to drive the adjustment component to move to the right and extend it into the interior of the lower die seat slot, and then rotates the fixed threaded sleeve and the sliding threaded sleeve to make the bottom end of the limit screw slide and be inserted into the vertical groove of the limit slot, thereby clamping the hinge sheet metal.

[0016] (2) The hinge rolling processing device has a rubber sleeve mounted on the right side of the clamping plate. When the clamping plate clamps the hinge sheet metal, the rubber sleeve contacts the surface of the sheet metal, thereby effectively protecting the hinge sheet metal from damage during the clamping process, reducing the friction between the clamping plate and the hinge sheet metal, and avoiding scratches or indentations during the processing, thereby ensuring the surface quality of the hinge.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 , the utility model provides a technical solution:

[0024] A hinge rolling processing device comprises a base 1, a hydraulic mechanism 5 is arranged on the top of the base 1, an upper die seat 4 is fixedly installed at the bottom of the hydraulic rod of the hydraulic mechanism 5, a lower die seat 3 is fixedly installed on the top of the base 1, and an adapting mechanism 2 is arranged on the left side of the lower die seat 3 for adapting, clamping and positioning hinge processing sheet metals of different thicknesses, and the adapting mechanism 2 includes:

[0025] The adjusting assembly 22 includes a threaded rod 221, a knob 222 is fixedly mounted on the left end of the threaded rod 221, and a clamping plate 223 is movably mounted on the right end of the threaded rod 221 through a bearing. The user rotates the threaded rod 221 through the knob 222 to adjust the distance between the clamping plate 223 and the right end of the sliding threaded sleeve 211, thereby clamping hinged sheet metals of different thicknesses;

[0026] The clamping assembly 21 is disposed on the left side of the lower die base 3 and is used to cooperate with the adjusting assembly 22 to fix and clamp the hinge sheet metal.

[0027] In this embodiment, the clamping assembly 21 includes a sliding threaded sleeve 211 that movably passes through the left side of the lower die base 3, a fixed threaded sleeve 213 is fixedly installed on the left end of the sliding threaded sleeve 211, and a push rod 214 is fixedly installed on the top of the fixed threaded sleeve 213. A limiting slot 212 is provided on the top of the sliding threaded sleeve 211, and the threaded rod 221 is threadedly rotated to pass through the fixed threaded sleeve 213 and the sliding threaded sleeve 211. The personnel pushes the sliding threaded sleeve 211 through the push rod 214 to drive the adjustment assembly 22 to move to the right and extend into the slot of the lower die base 3, and then rotates the fixed threaded sleeve 213 and the sliding threaded sleeve 211, so that the bottom end of the limiting screw 6 slides and is clamped into the vertical slot of the limiting slot 212, thereby achieving the clamping of the hinge sheet metal.

[0028] In this embodiment, a limiting screw 6 is movably installed on the left side of the top of the lower mold base 3, and the bottom end of the limiting screw 6 is inserted into and slides inside the limiting slot 212. The limiting slot 212 is L-shaped.

Then, the user adjusts the distance between the clamping plate 223 and the right end of the sliding threaded sleeve 211 by turning the knob 222 according to the thickness of the hinge sheet metal, adapts the thickness of the hinge sheet metal, and puts the pre-bent hinge sheet metal into the clamping block of the lower die seat 3. The personnel then pushes the sliding threaded sleeve 211 through the push rod 214 to drive the adjusting assembly 22 to move to the right and extend into the interior of the slot of the lower die seat 3, and then rotates the fixed threaded sleeve 213 and the sliding threaded sleeve 211 to make the bottom end of the limiting screw 6 slide and be inserted into the vertical slot of the limiting slot 212 to clamp the hinge sheet metal. Then the hydraulic rod of the hydraulic mechanism 5 drives the upper die seat 4 to descend, and the bending groove of the upper die seat 4 presses down the pre-bent part of the hinge sheet metal to roll the hinge sheet metal.
