[0025] Reference Figures 1 to 3 The utility model of the iron core steel plate cold rolling forming machine is made into the following embodiments:

[0026] A core steel plate cold rolling forming machine includes: an extrusion base 100, a pressing block 200 and an extrusion driving component 400.

[0027] The extrusion base 100 has an extrusion platform 110. The extrusion platform 110 has an extrusion support surface extending horizontally. The front side of the extrusion platform 110 has a molding rib 120, and the pressing block 200 is arranged at the rear side of the extrusion platform 110. The molding rib 120 and the pressing block 200 have extrusion surfaces arranged opposite to each other.

[0028] The extrusion driving member 400 has an extrusion driving end which is in transmission connection with the pressing block 200 and enables the pressing block 200 to move forward and backward relative to the extrusion base 100, so that the two extrusion surfaces are close to each other or away from each other.

[0029] In actual use, the steel strip coil is placed on the extrusion platform 110, and the extrusion driving component 400 drives the pressing block 200 to move toward the forming rib 120, the distance between the pressing block 200 and the forming rib 120 is reduced, and the two extrusion surfaces approach each other, so that the steel strip coil on the extrusion platform 110 is extruded and formed.

[0030] In this embodiment, the extrusion strip 300 can be detachably provided on the opposite sides of the forming rib 120 and the pressing block 200. The extrusion strip 300 is in the shape of a long strip and extends in the left-right direction. The extrusion surface is provided on the front side or the rear side of the extrusion strip 300. The thickness of the extrusion strip 300 can be set according to the thickness specification of the plate. By detachably replacing different extrusion strips 300, it can adapt to steel strip coils of different width specifications.

[0031] The pressing block 200 and the molding rib 120 are both provided with a plurality of slots arranged in a left-right arrangement on the opposite side. The slots are through-through in the up-down direction. One side of the extrusion strip 300 is provided with a plurality of buckle parts corresponding to the slots one by one. The buckle parts are embedded in the slots so that the extrusion strip 300 can be fixed on the edge of the pressing block 200 and the molding rib 120 on the opposite side.

[0032] A limiting rib 130 is provided at the left end of the extrusion platform 110. A feed port 140 is provided at the right end of the extrusion platform 110. The steel strip coil can be dragged into the extrusion platform 110 from the feed port 140. The limiting rib 130 is higher than the extrusion platform 110 and extends in the front-to-back direction. The limiting rib 130 can limit the end of the steel strip coil to prevent the steel strip coil from exceeding the range of the extrusion platform 110 after being compressed.

[0033] In a further embodiment, a feeding platform is further provided beside the feeding port 140. The feeding platform and the extrusion platform 110 are respectively provided on the left and right sides of the feeding port 140. The feeding platform and the extrusion platform 110 are flush with each other. The feeding port 140 has a material sorting rod extending forward and backward. The material sorting rod is arranged across the feeding port 140. When the steel strip coil enters the extrusion platform 110 from the feeding platform through the feeding port 140, the steel strip coil passes under the material sorting rod, and the material sorting rod can smooth the warped steel strip to make the steel strip coil as flat as possible.

[0034] In this embodiment, both left and right ends of the pressing block 200 are connected to the extrusion base 100 for sliding movement forward and backward, and the extrusion drive components 400 are arranged in pairs on the left and right. Specifically, both left and right sides of the extrusion base 100 have slide grooves 150 extending forward and backward. The two left and right slide grooves 150 are opened toward each other, and the left and right ends of the pressing block 200 are respectively slidably embedded in the two slide grooves 150. Since the pressure required for cold rolling forming is relatively large, in this embodiment, the extrusion drive component 400 is a hydraulic cylinder arranged along the front and back. The number of the extrusion drive components 400 is two, and the two extrusion drive components 400 are arranged in pairs on the left and right. The two extrusion drive components 400 are symmetrically arranged, and the spacing between the two extrusion drive components 400 and the left and right ends of the pressing block 200 is consistent, so that the force on the pressing block 200 is uniform and it is not easy to deflect. In some other embodiments, the extrusion drive component 400 can also adopt a linear drive component such as a cylinder, an electric push rod or a screw nut drive assembly according to needs.

[0035] Since the extrusion stress during cold rolling is relatively large, in order to prevent the steel strip coil from deforming and warping, in this embodiment, a pressing member 500 is provided above the extrusion platform 110. The pressing member 500 is used to press the steel strip coil onto the extrusion platform 110.

[0036] The pressing member 500 includes: a pressing beam 510 and a pressing piece 520. The pressing beam 510 is arranged above the extrusion platform 110. The pressing piece 520 is arranged at the lower side of the pressing beam 510. In actual use, the lower side of the pressing piece 520 is pressed tightly against the steel strip coil, so that it can always be pressed against the extrusion platform 110 during the pressing process.

[0037] The press beam 510 extends in the front-to-back direction, and both the front and rear ends of the press beam 510 are connected to the extrusion base 100. In order to facilitate the loading of the steel strip coil to a specific position of the extrusion platform 110, it is preferred that the press beam 510 can be opened and closed. Specifically, one end of the press beam 510 is rotatably connected to the extrusion base 100, so that the press beam 510 has a rotation axis extending left and right, and the other end of the press beam 510 is detachably connected to the extrusion base 100.

[0038] In a further embodiment, in order to meet different requirements for plate thickness, the pressing member 500 is adjustable in the up-down direction. Specifically, both front and rear ends of the extrusion base 100 are provided with an adjustment slide 160 adjustable in the up-down direction. The adjustment slide 160 is slidably connected to the extrusion base 100 through a linear slide rail extending up and down. The extrusion base 100 is rotatably provided with an adjustment screw 170 arranged in the up-down direction. The adjustment slide 160 is threadedly connected to the adjustment screw 170. The two ends of the pressing beam 510 are respectively connected to the two adjustment slides 160.

[0039] The two adjustment slides 160 are respectively a front adjustment seat and a rear adjustment seat. The front end of the press beam 510 is rotatably hinged with the front adjustment slide 160. The rear adjustment slide 160 has a connecting groove, and a baffle 161 is provided on the upper side of the connecting groove. The baffle 161 is detachably arranged on the rear adjustment slide 160. In this embodiment, one end of the baffle 161 is rotatably connected to the rear adjustment slide 160, and the other end is locked and connected to the rear adjustment slide 160 by a screw. The rear section of the press beam 510 is embedded in the connecting groove and is pressed in the connecting groove by the baffle 161.

[0040] The pressing piece 520 is in the shape of an elongated strip and extends in the horizontal direction. Since the spacing between the pressing block 200 and the forming rib 120 will change during the pressing process, in this embodiment, the pressing beam 510 is provided with a sliding connection block 511 along the front and rear. The middle part of the pressing piece 520 is rotatably connected with the connection block 511. A torsion spring is also provided between the pressing piece 520 and the connection block 511. The connection block 511 is slidably connected with the pressing beam 510 through a linear slide rail or a slide groove 150 structure. The elastic torque of the torsion spring acts on the pressing piece 520 and the pressing beam 510, so that the pressing piece 520 has a tendency to rotate relative to the pressing beam 510, so that the two ends of the pressing piece 520 are elastically abutted against the pressing block 200 or the forming rib 120 respectively.

[0041] In order to make the forming effect of the steel strip ring more stable, in this embodiment, a tensioning mechanism is provided on the left side of the extrusion platform 110. The tensioning mechanism includes: a transmission member, a tensioning plate and a tensioning column. The transmission member is used to connect the tensioning plate with the extrusion base 100. The axial direction of the tensioning column extends in the up-down direction, and the tensioning column is installed on the lower side of the tensioning plate.

[0042] The tensioning column is preferably arranged centrally between the molding rib 120 and the pressing block 200. In order to adapt to the change in the spacing between the molding rib 120 and the pressing block 200, in this embodiment, the transmission member includes a transmission arm arranged in pairs. The two transmission arms have hinged ends hinged to each other and transmission ends respectively connected to the molding rib 120 and the pressing block 200. The tensioning plate is installed at the hinged end.

[0043] The two transmission arms have the same length, and the hinged end is always on the perpendicular bisector of the line connecting the two transmission ends. When the spacing between the forming rib 120 and the pressing block 200 changes, the tensioning plate is always centrally arranged between the forming rib 120 and the pressing block 200.

[0044] Furthermore, the tensioning column is elastically mounted on the tensioning plate along the left-right direction, so that the tensioning column can be elastically tightened on the inner side of the steel belt material ring.

[0045] In order to avoid squeezing the tensioning column during the steel strip coil forming process, the tensioning column needs to be pulled out from the steel strip coil before the inner side is completely pressed. In this embodiment, the tensioning mechanism is further provided with a lifting component. The lifting component is used to drive the lower end of the tensioning column to move upward.

[0046] In some other embodiments, the tensioning mechanisms are arranged in pairs on the left and right sides of the extrusion platform 110. The two tensioning mechanisms arranged in pairs act on the steel strip coil in the left and right directions respectively.
