DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0024] REFERENCE Figures 1-6 The high-rigidity feature of the described sliding block stamping device is reflected in the cooperation of multiple key structural designs and components.

[0025] Firstly, the lower mold 1, as the basic bearing component of the whole device, bears the huge impact force in the stamping process. It is made of high-strength material, such as high-quality alloy steel, and is subjected to special heat treatment process to enhance the hardness and toughness of the material, so that it has good anti-deformation ability and fundamentally lays a foundation for the high rigidity of the device.

[0026] The upper end face of the lower mold 1 is designed with a placing groove 2 and a profile groove 12. These grooves are not simply recessed, but strictly follow high-precision process requirements in the processing process to ensure the perpendicularity and flatness of the groove wall, so that deformation will not occur due to local weak points when bearing pressure, and the overall rigidity is indirectly improved.

[0027] As for the rotating groove 15 and the meshing groove 13, the design and processing precision are extremely high. The inner wall of the rotating groove 15 is smooth and the size tolerance is controlled within a very small range, so that the double-headed screw rod 16 installed therein can rotate smoothly without shaking due to too large gap between the groove walls, and the stability of power transmission is ensured.

[0028] The meshing groove 13 is closely matched with the gear 14 at the end of the double-headed screw rod 16. The gear 14 has almost no backlash during meshing, ensuring the efficiency and accuracy of power transmission, and vibration will not occur due to poor meshing, thereby affecting the rigidity of the device.

[0029] The double-headed screw rod 16 has high structural strength, and appropriate high-strength screw rod material is selected. The diameter and pitch are accurately calculated and optimized to ensure that no torsional deformation occurs when transmitting the rotating force driven by the rack 8. The limiting mechanism matched therewith further enhances the rigidity performance.

[0030] The limiting rod 18 is a high-strength cylindrical rod, which is parallel to the double-end screw rod 16 and penetrates the moving block 17 accurately, thereby limiting the moving direction of the moving block 17 and providing lateral support to prevent the moving block 17 from tilting when being stressed, like reinforcing a "muscle" for the whole transmission chain.

[0031] The moving block 17 is connected with the limiting roller 9 through the insertion mechanism, and the matching of the connecting rod 11 and the insertion slot 19 is close, so that the limiting roller 9 can avoid the end of the plate to be processed 3 from being lifted up during the stamping operation.

[0032] The mounting frame 10 in the stabilizing mechanism is firmly connected to the lower die 1 through a bolt assembly, which firstly provides limiting for the limiting roller 9 to avoid the disconnection of the limiting roller 9 and the moving block 17, and secondly is convenient to be detached from the lower die 1, thereby realizing the convenient disassembly of the limiting roller 9.

[0033] On one side of the upper die 5, the hydraulic cylinder 4 serves as a power source, and the cylinder body and the piston rod are made of high-strength steel material, which has sufficient axial and radial stiffness and will not be bent and deformed due to pressure when driving the upper die 5 to move, thereby ensuring the stable pressing of the upper die 5. The sliding rod 7 and the sliding block 6 of the guiding mechanism have high matching precision, the sliding rod 7 is straight and rigid, the sliding block 6 is tightly sleeved on the sliding rod 7, and the sliding is smooth without jamming, thereby providing accurate guidance for the up-down reciprocating movement of the upper die 5, ensuring the high-precision alignment when the upper and lower dies are closed, avoiding the damage of the dies due to uneven stress caused by deflection, and effectively maintaining the high rigidity of the whole device.

[0034] In use, the plate to be processed 3 is placed in the placing groove 2, the limiting roller 9 is located at the higher position at both ends of the placing groove 2 in the initial state, then the upper die 5 is driven to descend by the hydraulic cylinder 4, in the descending process, the rack 8 meshes with the gear 14 to drive the double-end screw rod 16 to rotate, the moving block 17 drives the limiting roller 9 to move when the double-end screw rod 16 rotates, the two limiting rollers 9 move close to each other, in order to avoid the lifting of the plate to be processed 3 at both ends, since the two ends of the plate to be processed 3 gradually approach after being concave, the limiting roller 9 close to each other can always correspond to the two ends of the plate to be processed 3.

[0035] In the scheme, the mounting frame 10 can be removed, after the mounting frame 10 is removed, the mounting frame 10 can be disassembled, with the disassembly of the mounting frame 10, the transverse movement of the limiting roller 9 can make the connecting rod 11 at one end of the limiting roller 9 disengage from the insertion slot 19, thereby completing the disassembly of the limiting roller 9, and facilitating the maintenance and replacement of the limiting roller 9.

[0036] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
