[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] This utility model provides a device for partial delamination treatment of cold-rolled molybdenum sheets, referenced. Figure 1The system includes a processing table 1, with a top plate 2 horizontally positioned above it. The processing table 1 is connected to the top plate 2 via several connecting rods 10. A first pressing mechanism is vertically positioned on the top plate 2 to press the upper surface of the molybdenum plate 3 at the position to be cut. The first pressing mechanism includes a first pressure plate 41 and a first telescopic cylinder 43 for longitudinally displacing the first pressure plate 41. The length of the first pressure plate 41 is aligned with the width of the molybdenum plate 3. The cylinder body of the first telescopic cylinder 43 is vertically mounted on the top plate 2. The lower end of the first plate 41 is connected to the upper end face of the first pressure plate 41 via the first pressure plate seat 42. Several first telescopic cylinders 43 are provided, and the several first telescopic cylinders 43 are evenly spaced along the length direction of the first pressure plate 41. The lower end of the top plate 2 is also provided with a cutting component for cutting the molybdenum plate 3. The upper end of the cutting component is provided with a longitudinal reciprocating mechanism, and the upper end of the longitudinal reciprocating mechanism is provided with a transverse stepping displacement mechanism 7 for moving the cutting component along the width direction of the molybdenum plate 3. The transverse stepping displacement mechanism 7 is located on the top plate 2. By controlling the extension of the first telescopic cylinder 43, the first pressure plate 41 can be moved downward, thereby pressing the upper surface of the molybdenum plate 3. By providing a first pressing mechanism for pressing the upper end face of the molybdenum plate 3 on one side of the position to be cut on the molybdenum plate 3, and this side is the side of the intact part, the stability of the cutting component when cutting the molybdenum plate is improved, and the occurrence of delamination and peeling at the intact part of the molybdenum plate 3 can also be reduced.

[0031] Furthermore, as one implementation method, refer to Figure 1 and Figure 3 The four corners of the lower end face of the first pressure plate seat 42 are connected to the upper end face of the first pressure plate 41 via pressure sensors 44. The pressure sensors 44 are used to detect the clamping force of the first pressure plate 41. The working process and working principle of the pressure sensors 44 are existing mature technologies and will not be described in detail here. When the clamping force of the first pressure plate 41 reaches a preset threshold, the extension of the first telescopic cylinder 43 is stopped, which enables the first pressure plate 41 to have the same clamping force when clamping molybdenum plates of different thicknesses.

[0032] Furthermore, as one implementation method, refer to Figure 1 A second pressing mechanism 9 is also vertically arranged on the top plate 2 to press the other side of the upper end face of the molybdenum plate 3 to be cut. The structure of the second pressing mechanism 9 is the same as that of the first pressing mechanism. The second pressing mechanism 9 can press the other side of the part of the molybdenum plate 3 to be cut, which can further improve the cutting stability of the cutting part and further reduce the occurrence of delamination and peeling at the intact part of the molybdenum plate 3.

[0033] Furthermore, as a specific implementation method, refer to Figure 1 and Figure 2A first rectangular opening 71 is provided vertically along the width direction of the molybdenum plate 3 on the top plate 2. The lateral stepping displacement mechanism 7 includes a lead screw 72, the axial direction of which is along the length direction of the first rectangular opening 71. The two ends of the lead screw 72 are respectively connected to the inner wall of the first rectangular opening 71 through bearings. A ball nut block 73 is fitted on the lead screw 72. A stepper motor 74 for driving the lead screw 72 to rotate is provided at one end of the top plate 2. The stepper motor 74 is a forward and reverse servo motor. A movable plate 75 is provided on the lower end face of the ball nut block 73. The operation of the stepper motor 74 can drive the lead screw 72 to rotate around its axis, thereby causing the ball nut block 73 and the movable plate 75 to move gradually along the width direction of the molybdenum plate 3, and the length of each movement is not greater than the width of the cutting blade 51.

[0034] Furthermore, as a specific implementation method, refer to Figure 1 The longitudinal reciprocating retraction mechanism includes a vertically arranged reciprocating telescopic cylinder 61. The cylinder body of the reciprocating telescopic cylinder 61 is connected to the lower end face of the movable plate 75 via a U-shaped connecting seat 62. A horizontal plate 63 is arranged at the lower end of the reciprocating telescopic cylinder 61. During the interval after each movement of the movable plate 75, the reciprocating telescopic cylinder 61 completes one extension and retraction, thereby driving the cutting blade 51 to cut the molybdenum plate 3 downwards and lift upwards to await the next movement of the movable plate 75, thus completing the cutting work in the entire width direction of the molybdenum plate 3. After completion, the movable plate 75 and the cutting blade 51 are returned to their original positions by reversing the forward and reverse stepper motor 74.

[0035] Furthermore, as a specific implementation method, refer to Figure 2 The lateral stepping displacement mechanism 7 also includes a guide rod 76, the axial direction of which is arranged along the length of the first rectangular opening 71. The two ends of the guide rod 76 are respectively connected to the inner wall of the first rectangular opening 71. The upper end surface of the movable plate 75 is provided with a guide cylinder 77 that is adapted to the guide rod 76. This improves the stability of the movable plate 75 during displacement.

[0036] Furthermore, as a specific implementation method, refer to Figure 3 and Figure 4 The cutting component includes a cutting blade 51, which is arranged vertically downwards and its width direction is along the width direction of the molybdenum plate 3. A blade holder 51 is provided at the upper end of the cutting blade 51, and the upper end of the blade holder 51 is connected to the lower end face of the horizontal plate 63.

[0037] Furthermore, as a specific implementation method, refer to Figure 4The lower cutting edge of the cutting blade 51 is inclined at a certain angle along the width direction of the molybdenum plate 3. By setting the cutting blade with an inclined cutting edge and driving it through a longitudinal reciprocating mechanism and a transverse stepping displacement mechanism, the cutting blade can cut the molybdenum plate obliquely downwards along the width direction of the molybdenum plate one after another. The inclined setting can reduce the contact area with the molybdenum plate, increase the cutting force of the cutting blade, and enable the cutting blade to cut the entire thickness of multiple layers of the molybdenum plate simultaneously during cutting, which can further reduce the occurrence of delamination and peeling in the intact parts of the molybdenum plate.

[0038] Furthermore, as a specific implementation method, refer to Figure 1 A second rectangular opening 8 for accommodating the cutting blade 51 is provided on the processing table 1 directly below the cutting blade 51. The length direction of the second rectangular opening 8 is set along the width direction of the molybdenum plate 3.

[0039] Furthermore, as a specific implementation method, refer to Figure 3 and Figure 4 The lower end of the side of the cutting blade 51 near the first pressure plate 41 contacts the end face of the first pressure plate 41. Several countersunk holes 53 are provided on the upper end of the side of the cutting blade 51 near the first pressure plate 41. Fastening bolts 54 for connecting to the blade holder 51 are installed within the countersunk holes 53. The bolt heads of the fastening bolts 54 are located inside the countersunk holes 53 to prevent collision between the bolt heads and the first pressure plate 41 when the bolt heads move downwards.

[0040] The fact that the lower end of one side of the cutting blade 51 is in contact with the end face of the first pressure plate 41 can further reduce the occurrence of delamination and peeling on the intact part of the molybdenum plate 3.

[0041] Furthermore, as one implementation method, refer to Figure 1 and Figure 5 At the front and rear ends of the horizontal plate 63, vertically downward clamping auxiliary components 11 are respectively provided. Each clamping auxiliary component 11 includes a vertically arranged sleeve 111. The outer surface of the sleeve 111 is connected to the horizontal plate 63, and the upper end of the sleeve 111 is sealed. A movable rod 112 is coaxially fitted inside the sleeve 111. The lower end of the movable rod 112 extends to the outside of the sleeve 111 and is coaxially fitted with an auxiliary pressure plate 114. A return spring 113 is coaxially connected between the upper end of the movable rod 112 and the sleeve 111. Each time the horizontal plate 63 and the cutting blade 51 move downwards, the auxiliary pressure plate 114 can preferentially contact the upper surface of the first pressure plate 41 and clamp the first pressure plate 41. The clamping auxiliary components 11 further enhance the clamping force of the first pressure plate 41 and improve the stability of the cutting blade 51 during downward cutting. This further reduces the occurrence of delamination and peeling at the intact parts of the molybdenum plate 3.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
