Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting and processing, and particularly relates to a cutting device for mold manufacturing. Background Art

[0002] Plates in the shape of an isosceles trapezoid are used to manufacture concave or convex dies in molds. This shape helps the material flow along a specific angle during the forming process, thereby forming parts with precise dimensions and angles. Plates in the shape of an isosceles trapezoid are usually cut from a whole rectangular parallelepiped-shaped plate. During the cutting process, it is necessary to fixedly clamp the plates on both sides of the part to be cut, reduce the vibration generated by the plate during the cutting process, ensure the accuracy and straightness of the cutting path, and make the cutting edge smoother and neater.

[0003] The Chinese patent application document with the publication number CN119260059A discloses a two-end fixed aluminum profile cutting device, including a frame. On both sides at one end above the frame, there are connected end clamping groups for clamping the two ends of the aluminum profile. The end clamping group includes a fixed frame fixed at the end of the frame. Above the fixed frame, there is a clamping plate for placing the aluminum profile. The clamping plate is of an L-shaped structure, and one end of the clamping plate has a convex edge, which can realize the limit of one side of the aluminum profile. When in use, the two ends of the aluminum profile are respectively placed above the two clamping plates, so that one side surface of the aluminum profile fits against the convex edge at one end of the clamping plate, and then the cutting position is manually adjusted for cutting; when cutting a rectangular parallelepiped-shaped plate into an isosceles trapezoid using the above patent application document, since the convex edge cannot move relative to the clamping plate, only plates with fixed shapes at both ends can be clamped and the clamping positions are fixed. However, for a rectangular parallelepiped plate that needs to be cut into an isosceles trapezoid, the clamping assembly needs to clamp a corner of the rectangular parallelepiped plate to facilitate cutting the waist of the isosceles trapezoid, and also needs to clamp one end of the isosceles trapezoid with a waist to facilitate cutting the other waist of the isosceles trapezoid. In addition, the orientation of the clamping assembly needs to be changed so that the two cut isosceles trapezoids share a waist to avoid waste of the plate. The clamping assembly in the above patent application cannot meet the fixed clamping of both ends of the rectangular parallelepiped plate cut into an isosceles trapezoid. Summary of the Invention

[0004] The present invention provides a cutting device for mold manufacturing to solve the technical problem that during the process of cutting a rectangular parallelepiped plate into an isosceles trapezoid part, the plate vibrates due to the lack of fixed clamping at both ends of the plate, resulting in an uneven cutting edge.

[0005] To solve the above problems, the present invention adopts the following technical solutions:

[0006] A cutting device for mold manufacturing includes a frame, a clamping module for clamping and fixing both ends of the plate, and a cutting module for cutting the plate;

[0007] The frame is used to horizontally support the plate.

[0008] The clamping module includes a stop frame, a baffle, and a moving frame. The stop frame has a right-angle slot one and a vertical section. The stop frame is horizontally slidably assembled on the frame and is rotationally assembled on the frame around the vertical axis. The stop frame is used to fit with both ends of the plate to control the lateral position of the plate. The baffle is slidably assembled on the stop frame. When one end face of the plate is in contact with the vertical section, the baffle is used to fit with both sides of the plate to control the longitudinal position of the plate. The moving frame is provided with a right-angle slot two. When one corner of one end of the plate is engaged in the right-angle slot one, the right-angle slot two is used to engage the other corner of one end of the plate to control the longitudinal position of one end of the plate.

[0009] The cutting module includes a cutting torch. The cutting torch is used to move relative to the plate to cut the plate into a plurality of isosceles trapezoid parts.

[0010] When cutting a cuboid plate into a plurality of isosceles trapezoids, the vertical section of one of the stop frames is in contact with one end face of the plate, and the baffle is in contact with both side faces of the stop frame. The right-angle slot one of the other stop frame engages one of the right angles at the other end of the plate, and the right-angle slot two on the moving frame engages the other right angle at the other end of the plate. At this time, the plate is fixed between the stop frame, the baffle, and the moving frame. The cutting torch starts from the corner point of the plate in the right-angle slot two and moves relative to the plate to cut off one corner of the plate, forming one waist of the isosceles trapezoid part. Adjust the stop frame so that the vertical section of the stop frame is in contact with the end face of the plate from which one corner has been cut off, and then adjust the baffle so that the baffle is in contact with both side faces of the plate. At this time, the plate is re-fixed on the stop frame, and the cutting torch moves relative to the plate to cut out an isosceles trapezoid part. The cutting surface forms the other waist of the isosceles trapezoid and is also one waist of the next isosceles trapezoid part. The device is flexible in use, can clamp both ends of the cuboid plate whose shape changes during the cutting process, prevent the plate from vibrating, and ensure that the cutting edge is flat.

[0011] Furthermore, the baffle is horizontally slidably assembled on the stop frame along a direction parallel to the vertical section and is rotationally assembled on the stop frame around the vertical axis.

[0012] When the stop frame moves to fit both ends of the plate, the baffles move away from each other to avoid touching the plate. When the stop frame fits with both ends of the plate, the baffles move closer to each other and rotate so that the baffles are in contact with both sides of the plate, increasing the contact area between the plate and the baffles and further reducing the vibration of the plate during the cutting process.

[0013] Furthermore, the stop frame is provided with two right-angle slots one, and the two right-angle slots one are symmetrically arranged horizontally and perpendicular to the axis of symmetry of the vertical section.

[0014] The user can select a suitable right-angle card slot 1 according to actual needs to adapt to different cutting trajectories of the board.

[0015] Furthermore, the moving frame is slidably assembled on the stopping frame along a horizontal direction perpendicular to the vertical section plane, and the moving frame is slidably assembled on the stopping frame along a horizontal direction parallel to the side wall of the right-angle card slot 1 close to the symmetry axis.

[0016] When one corner of the board with different sizes is engaged in the right-angle card slot 1, the moving frame can change according to the position of the other corner of the board end, so that the right-angle card slot 2 can engage the other corner of the board end.

[0017] Furthermore, when the other corner of the board is engaged in the right-angle card slot 2, a circumferentially closed and vertically extending gap for avoiding the cutting torch is formed between the outer peripheral surface of the board and the inner peripheral surface of the moving frame.

[0018] There is a gap between the outer peripheral surface of the board located in the right-angle card slot 2 and the inner peripheral surface of the moving frame, so that the cutting torch can be placed at the corner point of one corner of the board in the right-angle card slot 2.

[0019] Furthermore, the stopping frame is longitudinally slidably assembled on the machine frame.

[0020] The stopping frame can move horizontally, longitudinally, and can also rotate around the vertical axis. The stopping frame can freely change its position according to actual clamping needs, and is flexible to use.

[0021] Furthermore, the cutting torch is longitudinally reciprocatingly slidably assembled on the machine frame.

[0022] The cutting torch slides longitudinally and reciprocally, and the stopping frame slides horizontally, so that the cutting torch can cut out the waist of an isosceles trapezoid.

[0023] Furthermore, a plurality of universal ball bearings are provided on the machine frame. The spherical rollers of the universal ball bearings are used to support the board. A pressing plate is vertically slidably assembled on the stopping frame. The pressing plate is used to fixedly clamp the board with the universal ball bearings in the up and down direction.

[0024] The pressing plate and the universal ball bearings limit the board in the vertical direction to prevent the board from moving up and down during the cutting process, and further increase the stability of the board during the cutting process.

[0025] The beneficial effects of the present invention are:

[0026] Adjust the stopping frame so that the vertical section plane of the stopping frame is longitudinally arranged. Place the board to be cut on the universal ball bearings. Move the baffle so that the baffle fits against the two side surfaces of the board. Move the stopping frame so that the vertical section plane of the stopping frame fits against the end surface of the board to determine the starting position of the board;

[0027] Move the stop frame close to the cutting torch so that the first right-angle card slot clamps one corner at one end of the plate. Move the moving frame so that the second right-angle card slot clamps the other corner at one end of the plate. At this time, one end of the plate is clamped and fixed by the first right-angle card slot and the second right-angle card slot, and the other end of the plate is fixed by the vertical cutting surface and the baffle. The plate is fixed in the horizontal direction. Press down the pressing plate until it contacts the top of the plate, and the plate is fixed in the vertical direction. The cutting torch is opposite to the corner point of the plate in the second right-angle card slot, and the cutting torch starts cutting. The two stop frames move horizontally at the same time, and the cutting torch moves longitudinally to cut off one corner of the plate;

[0028] Adjust the stop frame close to one end of the plate to be cut so that the vertical cutting surface fits the inclined surface cut out on the plate. Rotate the baffles and move them closer to each other so that the baffles fit the two side surfaces of the plate. Lower the pressing plate to fix the plate again. The two baffles move horizontally at the same time, and the cutting torch moves longitudinally to cut the first isosceles trapezoidal part on the plate; During the whole cutting process, the stop frame, the baffle, and the moving frame cooperate with each other to be able to fix and clamp both ends of the plate whose shape changes continuously into an isosceles trapezoid, reduce the vibration during cutting, and ensure that the cutting surface is smooth and flat.

[0058] The usage method of the present invention is as follows:

[0059] ① Place the plate 2; adjust the two stop brackets 24 so that the two stop brackets 24 extend longitudinally and are parallel to each other. Place the plate 2 with the cut trajectory divided on the frame 1. The plate 2 is in contact with the spherical rollers of the universal ball bearings 8. Start the motor IV 35 to make the two stop brackets 24 approach horizontally. At the same time, start the motor III 23 and the linear actuator IV 14 to rotate the baffle 29 to be parallel to the side surface of the plate 2 and make the two opposite baffles 29 approach each other until the vertical cutting surface 33 fits the two end surfaces of the plate 2, and the baffle 29 fits the two side surfaces of the plate 2 to position the baffle 29. At this time, the relative positional relationship between the plate 2 and the stop brackets 24 and the baffle 29 is as Figure 11 shown;

[0060] ②Fix the plate 2; Start the fourth motor 35 on the second supporting bracket 7 to drive the stop bracket 24 away from one end of the plate 2. Start the second linear actuator 12 and the second motor 22. The stop bracket 24 on the second supporting bracket 7 moves, so that one of the first right-angle slots 27 is adapted to a corner of the plate 2 where no cutting line is drawn. Reverse-start the fourth motor 35 on the second supporting bracket 7, and the stop bracket 24 approaches one end of the plate 2, so that the corner of the plate 2 where no cutting line is drawn is engaged in the first right-angle slot 27. One of the fifth linear actuators 15 shortens, driving the moving frame 30 to move towards the other corner of the plate 2 until the other corner of the plate 2 is engaged in the second right-angle slot 28. At this time, a circumferentially closed and vertically extending L-shaped gap is formed between the side surface of the plate 2 located in the second right-angle slot 28 and the inner wall of the moving frame 30. At this time, one end of the plate 2 on the second supporting bracket 7 is longitudinally fixed by the stop bracket 24 and the moving frame 30, and the relative positional relationship between the plate 2 and the stop bracket 24 and the moving frame 30 is as Figure 12 and Figure 13 shown; Extend the third linear actuator 13 on the first supporting bracket 6 and the second supporting bracket 7, and the pressing plate 26 moves downward and presses tightly against the top surface of the plate 2. The pressing plate 26 and the universal ball bearing 8 fix the plate 2 up and down, and the two stop brackets 24 fix the plate 2 horizontally;

[0061] ③Cut the plate 2 for the first time; Start the two third motors 23 and start the first motor 21 at the same time, so that the cutting torch 9 is vertically opposite to the corner point of one corner of the plate 2 in the moving frame 30. Extend the first linear actuator 11 to fit the cutting torch 9 with the corner point of one corner of the plate 2 in the moving frame 30; Then the third motor 23 drives the second lead screw 19 to rotate, and the stop bracket 24 drives the plate 2 to move horizontally in the direction of the second supporting bracket 7 synchronously. The first motor 21 drives the cutting torch 9 to move longitudinally, and the cutting torch 9 cuts off one corner of the plate 2. Then the first linear actuator 11 shortens and the cutting torch 9 moves upward;

[0062] ④Unload the material; Extend the third linear actuator 13 and the fifth linear actuator 15 on the second supporting bracket 7. The pressing plate 26 moves upward and leaves the plate 2, and the moving frame 30 moves away from the plate 2; Start the fourth motor 35 on the second supporting bracket 7 to drive the stop bracket 24 on the second supporting bracket 7 away from the cut plate 2. At this time, the cut plate 2 can be removed;

[0063] ⑤Re-clamp one end of the plate 2 on the second supporting bracket 7; Start the fourth motor 35 on the second supporting bracket 7 to make the stop bracket 24 approach the plate 2. At the same time, adjust the second motor 22 and the second linear actuator 12 on the second supporting bracket 7 so that the vertical section 33 is fitted with the end face of the cut plate 2; Start the third motor 23 to make the baffle 29 rotate to be parallel to the side surface of the plate 2, and the fourth linear actuator 14 shortens synchronously to make the two opposite baffles 29 approach each other until the baffles 29 are fitted with the two side surfaces of the plate 2. At this time, the relative positional relationship between the plate 2 and the stop bracket 24 and the baffle 29 is as Figure 14 shown;

[0064] ⑥ Cut the sheet 2 again; start the fourth motor 35 to drive the sheet 2 to move horizontally so that the cutting torch 9 is vertically opposite to the next cutting starting point of the sheet 2; extend the first linear actuator 11, and lower the cutting torch 9 until it contacts the sheet 2; move the cutting torch 9 longitudinally and the sheet 2 horizontally to perform secondary cutting on the sheet 2, and at this time, the first isosceles trapezoidal part is cut off.

[0065] Repeat steps ④-⑥ to perform multiple cuts on the sheet 2 until the cutting torch 9 is about to cut out the last isosceles trapezoidal part. As Figure 15 shown, at this time, the positional relationship between the stop bracket 24 on the first support bracket 6 and the sheet 2 is as shown in Figure 12 and Figure 13 shown, and the positional relationship between the stop bracket 24 on the second support bracket 7 and the sheet 2 is as shown in Figure 14 shown. Then, refer to step ⑥ to complete the cutting work of the sheet 2.
