[0034] Example 1

[0035] This embodiment provides a technical solution: a precision slitting machine, such as... Figures 1-5 As shown, it includes a slitting machine housing, a workpiece placement mechanism, an auxiliary conveying mechanism, a positioning bracket, a positioning shearing mechanism, and a shearing lifting mechanism.

[0036] The workpiece placement mechanism is installed and connected to the upper middle of the slitting machine housing. Personnel can place the steel plate to be sheared onto the workpiece placement mechanism, which can stably position it in the upper middle of the slitting machine housing. An auxiliary conveying mechanism is installed and connected to the inner side of the upper end of the workpiece placement mechanism, providing rolling assistance. The auxiliary conveying mechanism is connected to a pneumatic device, allowing it to receive external air pressure for protruding rolling. Positioning brackets are fixed to both sides of the upper end of the slitting machine housing, providing positioning. A positioning shearing mechanism is installed and connected to the positioning brackets, enabling positioning, lifting, and shearing on the positioning brackets. A shearing lifting mechanism is installed and connected to the positioning brackets, allowing stable lifting and lowering on the positioning brackets. The shearing lifting mechanism is connected to the positioning shearing mechanism, driving it to lift and lower for shearing.

[0037] The slitting machine housing includes a bottom housing 1, which is hollow inside to store items. The front inner side of the bottom housing 1 is connected to a housing door 11 via a hinge, allowing personnel to open the housing door 11 to put items into the bottom housing 1. Positioning brackets are installed on both sides of the upper end of the bottom housing 1, which can be used for positioning.

[0038] The positioning bracket includes a positioning column 12. When the positioning column 12 is vertical, it serves as a limit. The lower end of the positioning column 12 is fixedly connected to a screw mounting plate 122. The positioning column 12 can be installed correspondingly through the screw mounting plate 122. The screw mounting plate 122 is connected to the bottom box 1 by screws, which facilitates installation and removal.

[0039] like Figure 1 , Figure 3 and Figure 4 As shown, the workpiece placement mechanism includes a workpiece placement seat 2, the lower end of which is fixed to the bottom box 1, allowing the workpiece placement seat 2 to be stably placed on the bottom box 1. A lower blade base 22 is fixedly connected to the middle of the upper end of the workpiece placement seat 2, allowing the workpiece placement seat 2 to move the lower blade base 22. An auxiliary conveying mechanism is installed inside the workpiece placement seat 2 and the lower blade base 22, which can adjust the position by rolling an auxiliary conveying steel plate. A lower shearing blade 21 is installed on the inner end of the lower blade base 22 by screws, allowing the lower blade base 22 to perform shearing through the lower shearing blade 21.

[0040] The positioning and shearing mechanism includes a double-hole positioning plate 5. Positioning sleeve holes 121 are provided on the inner sides of both ends of the double-hole positioning plate 5. The double-hole positioning plate 5 can be fitted and installed through the positioning sleeve holes 121. The double-hole positioning plate 5 is fitted onto the positioning column 12 through the positioning sleeve holes 121. The double-hole positioning plate 5 can be positioned and moved on the positioning column 12 through the positioning sleeve holes 121. An upper blade mounting seat 6 is fixedly connected to the lower end of the double-hole positioning plate 5. The position and height of the upper blade mounting seat 6 can be changed when the double-hole positioning plate 5 is raised or lowered. An upper shearing blade 61 is installed at the front end of the upper blade mounting seat 6 by screws. The position and height of the upper shearing blade 61 can be changed when the upper shearing blade 61 intersects with the lower shearing blade 21, allowing for longitudinal shearing of the steel plate. A laser body 7 is fixedly connected to the front end of the double-hole positioning plate 5. The laser body 7 can emit light from the double-hole positioning plate 5 to determine the shearing position.

[0041] The shearing lifting mechanism includes a positioning panel 3, which can be stably placed on the positioning column 12. A hydraulic telescopic cylinder 4 is installed in the middle of the inner side of the positioning panel 3. The hydraulic telescopic cylinder 4 can stably extend and retract on the positioning panel 3. The telescopic rod end of the hydraulic telescopic cylinder 4 is connected to the double-hole positioning plate 5 by screws. When the telescopic rod of the hydraulic telescopic cylinder 4 extends and retracts, it can change the position of the double-hole positioning plate 5, so that the height can be changed to shear the steel plate.

[0042] During use, the operator can place the steel plate to be sheared on the workpiece placement mechanism. The auxiliary conveying mechanism can roll to assist the workpiece placement mechanism from the upper inner side. The auxiliary conveying mechanism is connected to the pneumatic device, so it can receive external air pressure for protruding rolling. This makes it more convenient to place, adjust, and shear the steel plate. The positioning bracket can be positioned on both sides of the upper end of the slitting machine housing. The positioning shearing mechanism can be positioned and lifted on the positioning bracket for shearing. The shearing lifting mechanism can be stably lifted and lowered on the positioning bracket. The shearing lifting mechanism can drive the positioning shearing mechanism to lift and lower for shearing.

[0043] Example 2

[0044] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 1 , Figure 3 and Figure 4As shown, to further better realize this utility model, the following configuration is specifically adopted: the auxiliary conveying mechanism includes a hollow sleeve plate 24, with an air inlet pipe 25 fixedly connected to the lower end of the hollow sleeve plate 24. The air inlet pipe 25 can convey gas from bottom to top into the hollow sleeve plate 24. The air inlet pipe 25 is connected to a pneumatic device to receive gas. A tension spring 26 is fixedly connected to the bottom inside the hollow sleeve plate 24. The tension spring 26 can be elastically pulled, and the upper end of the tension spring 26 is located inside the hollow sleeve plate 24. A movable lifting plate 27 is fitted in place. The incoming gas causes the movable lifting plate 27 to rise in the hollow sleeve plate 24. The movable lifting plate 27 is then subjected to a restoring force by a tension spring 26. When the gas pressure disappears, the tension spring 26 can be driven to return to its original position. A rolling ball 23 is rotatably installed on the inner side of the upper end of the movable lifting plate 27. When the movable lifting plate 27 is raised, the rolling ball 23 is driven to be exposed from the hollow sleeve plate 24. Then, the workpiece is assisted in the adjustment by the rolling ball 23, which facilitates the adjustment by personnel.

[0045] The upper inner side of the hollow sleeve plate 24 has holes corresponding to the rolling ball 23, so that they can be passed through for use.
