DETAILED DESCRIPTION
[0026] The present invention is further described in detail below with reference to examples and specific implementation modes.
[0027] like Figure 1-4 As shown, a center positioning shearing room discharging and clamping cylinder device based on the movement of the knife platform, the structure of which includes a knife platform 15, the top surface of the knife platform 15 is slidably connected to the side plates 23 on both sides through the second slider and the slide rail 14, and a moving platform rack fixing tool 22 is also provided on the top surface of the knife platform 15 between the second slider and the slide rail 14, and a horizontally arranged moving platform rack 24 is installed on the moving platform rack fixing tool 22, the bottom of the inner surface of the side plates 23 on both sides is connected to the gear fixing tool 21, and the gear fixing tool 21 on both sides is connected to the shearing room clamping cylinder gear 9 through a rotating shaft, and the bottom of the shearing room clamping cylinder gear 9 is meshed and connected to the moving platform rack 24, and the middle part of the inner surface of the side plates 23 on both sides is also slidably connected to the shearing room clamping cylinder driving device 5 through the first slider and the slide rail 6, and the shearing room clamping cylinder The output end of the driving device 5 is connected to the shear clamping cylinder device 4. The rack fixing tooling 7 is installed at the lower part of the shear clamping cylinder driving device 5. The rack fixing tooling 7 is connected to the horizontally set shear clamping cylinder rack 8. The shear clamping cylinder rack 8 is meshed and connected to the top of the shear clamping cylinder gear 9. The rear ends of the side plates 23 on both sides are connected to the side rear plates 13, and the tops are connected to the upper cover plate 12. The front ends of the side plates 23 on both sides are respectively provided with a driving side pulling roller 1 and a driven side pulling roller 2. The rear side of the bottom surface of the upper cover plate 12 is equipped with a motor 10. The output end of the motor 10 is driven and connected to the driving side pulling roller 1 through a driving shaft 11. The top of the driving side pulling roller 1 is connected to a driving roller lifting device 3. The driving roller lifting device 3 is installed on the bottom surface of the upper cover plate 12, and the driven side pulling roller 2 is fixed on the inner side surfaces of the side plates 23 on both sides.
[0028] The first slide block and the slide rail 6 are block-type rails.
[0029] The overall tooling above the second slider and the slide rail 14 slides through the second slider and the slide rail 14. When the knife platform 15 moves, it is relatively displaced with the knife platform 15. The whole is fixed on the machine table 18 through the fixed shaft 16 and the fixed shaft fixing tooling 17. Specifically, the bottom of the knife platform 15 is connected to the top of the fixed shaft 16, the bottom end of the fixed shaft 16 is inserted into the top of the fixed shaft fixing tooling 17, and the bottom of the fixed shaft fixing tooling 17 is connected to the top surface of the machine table 18.
[0030] The mobile platform rack fixing fixture 22 and the mobile platform rack 24 are completely fixed on the knife platform 15 and move forward and backward along with the knife platform 15 .
[0031] The inter-shear clamping cylinder gear 9 is precisely matched with the mobile platform rack 24 and the inter-shear clamping cylinder rack 8. The inter-shear clamping cylinder gear 9 is fixed on the overall tooling. When the knife platform 15 moves, the inter-shear clamping cylinder gear 9 and the mobile platform rack 24 are relatively displaced, and the inter-shear clamping cylinder gear 9 rotates, which will drive the inter-shear clamping cylinder rack 8 to displace in the opposite direction and equal to the displacement of the knife platform 15.
[0032] The output end of the shear clamping cylinder driving device 5 is displaced with a stroke of 10 mm to drive the shear clamping cylinder device 4.
[0033] The driven side pulling roller 2 is specifically rotatably connected to the pulling roller bearing seat 20, and the pulling roller bearing seat 20 is fixed on the inner side of the side plates 23 on both sides. The top end of the driven side pulling roller 2 is flush with the center of the cross-cutting line track and directly contacts the coil, serving as a reference surface for tightening.
[0034] like Figure 4 As shown, the driving side pulling roller 1 and the driven side pulling roller 2 have the same structure and both include a pulling roller A5. The pulling roller bearing seat 20 includes an upper pulling roller bearing seat A1 and a lower pulling roller bearing seat A2. The upper pulling roller bearing seat A1 is connected to the lower pulling roller bearing seat A2 by bolt locking. The bearing A3 is clamped in the bearing grooves of the upper pulling roller bearing seat A1 and the lower pulling roller bearing seat A2. The pulling roller shaft A4 is installed in the bearing A3 and connected to the pulling roller A5 through a keyway.
[0035] The driving roller lifting device 3 includes a cylinder connecting rod B2, A1 on the pulling roller bearing seat of the driving side pulling roller 1 is connected to the bottom end of the cylinder connecting rod B2, and the top end of the cylinder connecting rod B2 is connected to the output end of the cylinder B1. The cylinder B1 is installed on the bottom surface of the upper cover plate 12, and the two sides of A2 under the pulling roller bearing seat of the driving side pulling roller 1 are slidably connected to the inner side of the side plate 23 through a third slider and a slide rail.
[0036] The bottom surface of the upper cover plate 12 is also connected to the second L-shaped bracket B3, and the bottom of the second L-shaped bracket B3 is provided with a positioning rod waist slot B4. A positioning rod passing through the positioning rod waist slot B4 is provided on the lower A2 of the pull roller bearing seat of the driving side pull roller 1. The driving side pull roller 1 can be displaced in the vertical direction within 10mm; when the cylinder connecting rod B2 is removed, the driving side pull roller 1 and the driving roller lifting device 3 can be kept from falling as a whole.
[0037] The output end of the motor 10 is specifically connected to one end of the drive shaft 11 through a coupling, and the other end of the drive shaft 11 is also connected to the pulling roller A5 through a coupling. The length of the drive shaft 11 is relatively large, and the up and down sliding distance of the driving side pulling roller 1 is relatively small, so the rotation angle of the drive shaft 11 is very small, and this small angle rotation will not damage the coupling; at the same time, when the driving side pulling roller 1 falls, the output shaft of the motor 10, the drive shaft 11 and the pulling roller A5 are coaxial, and there is no eccentricity during the rotation process, so the transmission effect is not affected.
[0038] According to the above structure, when the cross-cutting line track is adjusted, taking the track expansion as an example, the knife platform 15 will move toward the operating side, and its distance is equal to the moving distance of the single-sided track, but in the opposite direction; at this time, under the fixation of the fixed shaft 16, the tooling as a whole moves toward the non-operating side relative to the knife platform 15, and the mobile platform rack fixing tooling 22 fixes the rack to move with the knife platform 15, and the gear fixing tooling 21 is fixed on the tooling, so the gear is fixed by the gear fixing tooling 21 and produces relative displacement with the rack, the gear rotates, and at the same time transmits the power to the upper rack, driving the shear room clamping cylinder device 4 to move in the same direction as the track; at this time, the adjustment part is completed and the production part is entered.
[0039] All the components mentioned above are prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
