[0010] The pressing plate does not contact the top of the fixed cover in an initial state.

[0011] As a further improvement of the present technical solution, the telescopic end of the electric telescopic rod is fixedly connected to a pressure block, a stopper is fixedly connected between the surface of the pressure block and the inner side of the ring, a fixed limit block is fixedly connected to the surface of the pressure block and below the stopper, an empty groove is opened on the inner side of the ring, a second spring is fixedly connected to the inner cavity of the empty groove, and one end of the second spring is fixedly connected to a movable limit block.

[0012] As a further improvement of the technical solution, an extrusion block is provided on the top of the fixed cover, the bottom of the extrusion block passes through the top of the fixed cover, and the bottom of the extrusion block extends to a position flush with the top of the inner side of the fixed cover, both sides of the top of the extrusion block are fixedly connected with side panels, the bottom of the side panels is fixedly connected with a vertical rod, the bottom end of the vertical rod passes through the top of the fixed cover, and the bottom of the side panels and the surface surrounding the vertical rod are fixedly connected with a first spring.

[0013] As a further improvement of the technical solution, sliding plates are provided on both sides of the top of the placement plate, a fixing frame is fixedly connected to the placement plate, a hydraulic cylinder is fixedly connected to the surface of the fixing frame, and the telescopic end of the hydraulic cylinder is in contact with the surface of the sliding plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the cutting device used for manufacturing metal doors and windows, metal parts are placed on a placement plate, and the sliding plates on both sides are driven by a hydraulic cylinder to clamp the metal parts so that the metal parts will not deviate left and right, and then the fixed cover is used to squeeze the fixed top so that the metal parts will not shake up and down.

[0018] 2. In the cutting device for manufacturing metal doors and windows, when the thickness of the metal parts is less than the height of the sliding plate, the fixed cover cannot squeeze and fix the metal parts. At this time, the telescopic end of the electric telescopic rod extends to drive the extrusion plate to squeeze the fixed cover. When the fixed cover is completely in contact with the top of the sliding plate, the fixed cover cannot drop. At this time, the electric telescopic rod continues to extend, and the movable limit block is squeezed and deformed under the huge extrusion force of the fixed limit block, causing the fixed limit block to squeeze through. At this time, the electric telescopic rod drives the pressure block to continue to drop to squeeze the extrusion block. The extrusion block is forced to pass through the fixed cover to squeeze and fix the metal parts on the placement plate. Metal parts of different thicknesses can be clamped, which has a wide range of applications and reduces the difficulty of operation. BRIEF DESCRIPTION OF THE DRAWINGS

In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a cutting device for metal door and window manufacturing, including a base 1, a mounting platform 2 is fixedly connected to the top of the base 1, a rotating member 3 is fixedly connected to the top of the mounting platform 2, a body 4 is rotatably connected to the rotating member 3, a blade 6 is rotatably connected to one side of the body 4, a protective cover 5 is fixedly connected to one side of the body 4 and located outside the blade 6, and a handle 7 is fixedly connected to one side of the body 4;

[0033] Also includes:

[0034] A placing plate 9, the bottom of which is fixedly connected with a pad 8, the bottom of which is fixedly connected with the top of the base 1, and the top of the placing plate 9 is used to place the metal parts to be cut;

[0035] The fixed cover 10 is located directly above the placement plate 9 and cooperates with the placement plate 9 to clamp and fix the metal parts. The fixed cover 10 can move vertically above the placement plate 9 to adjust the clamping distance between the fixed cover 10 and the placement plate 9. Sliding plates 35 are provided on both sides of the top of the placement plate 9. A fixed frame 24 is fixedly connected to the placement plate 9. A hydraulic cylinder 25 is fixedly connected to the surface of the fixed frame 24. The telescopic end of the hydraulic cylinder 25 contacts the surface of the sliding plate 35.

[0036] The metal parts are placed on the placement plate 9, and the sliding plates 35 on both sides are driven by the hydraulic cylinder 25 to clamp the metal parts so that the metal parts will not deviate left and right, and then the fixed cover 10 is used to squeeze and fix the top so that the metal parts will not shake up and down. The metal parts are firmly clamped and will not deviate or shake during cutting, thereby improving the cutting accuracy, reducing the occurrence of defective products, saving costs, and reducing safety hazards.

[0037] A moving block 11 is provided at the top of the base 1 and at one side of the mounting platform 2, a T-shaped slider 12 is fixedly connected to the bottom of the moving block 11, a T-shaped slide groove 13 is provided at the top of the base 1, the bottom of the T-shaped slider 12 is slidably connected to the inner cavity of the T-shaped slide groove 13, a support rod 14 is fixedly connected to the top of the moving block 11, a circuit rod 15 is fixedly connected to the top of the support rod 14, an electric telescopic rod 16 is fixedly connected to one end of the circuit rod 15, a circular ring 17 is fixedly connected to the telescopic end of the electric telescopic rod 16, a connecting rod 18 is fixedly connected to the surface of the circular ring 17, and an extrusion plate 19 is fixedly connected to one end of the connecting rod 18;

[0038] The extrusion plate 19 does not contact the top of the fixed cover 10 in the initial state, so that the fixed cover 10 has space to continue to move upward. As the electric telescopic rod 16 contracts, the distance between the extrusion plate 19 and the fixed cover 10 becomes farther, and thicker metal parts can be placed between the fixed cover 10 and the placement plate 9, thereby increasing the scope of application of the device.

[0039] When the metal part is very long or very short, the electric telescopic rod 16 should be moved to the middle of the metal part to ensure stable extrusion and clamping, so that the T-shaped slider 12 at the bottom of the moving block 11 on one side of the base 1 slides in the T-shaped slide groove 13 at the top of the base 1, and the support rod 14, circuit rod 15 and electric telescopic rod 16 at the top of the moving block 11 move accordingly. The contact surface between the T-shaped slide groove 13 and the T-shaped slider 12 is relatively rough, and will not move without external force, and will not move during normal cutting.

[0040] The telescopic end of the electric telescopic rod 16 is fixedly connected to a pressure block 26, a stopper 36 is fixedly connected between the surface of the pressure block 26 and the inner side of the ring 17, a fixed limit block 27 is fixedly connected to the surface of the pressure block 26 and below the stopper 36, a slot 28 is provided on the inner side of the ring 17, a second spring 29 is fixedly connected to the inner cavity of the slot 28, and a movable limit block 30 is fixedly connected to one end of the second spring 29.

[0041] The position where the upper part of the movable limit block 30 contacts the fixed limit block 27 is an inclined surface with a smaller bevel angle. Under normal circumstances, the fixed limit block 27 contacts the movable limit block 30 to drive the extrusion plate 19 to descend, and the force exerted on the movable limit block 30 will not cause the movable limit block 30 to retract into the empty groove 28. When the extrusion plate 19 cannot descend and the fixed limit block 27 continues to squeeze the movable limit block 30, the movable limit block 30 enters the empty groove 28 under the action of the squeezing force. At this time, the telescopic end of the electric telescopic rod 16 is not constrained and can continue to extend after breaking away from the ring 17. When the electric telescopic rod 16 is retracted, the contact surface of the fixed limit block 27 and the movable limit block 30 are both inclined surfaces. Under the action of gravity and the squeezing of the fixed limit block 27, the movable limit block 30 retracts into the empty groove 28 to allow the fixed limit block 27 to pass through. The fixed limit block 27 drives the ring 17 to continue to move by being limited by the stopper 36, and the movable limit block 30 pops out again under the action of the second spring 29.

[0042] An extrusion block 20 is provided on the top of the fixed cover 10, and the bottom of the extrusion block 20 passes through the top of the fixed cover 10, and the bottom of the extrusion block 20 extends to a position flush with the inner top of the fixed cover 10, and side panels 21 are fixedly connected to both sides of the top of the extrusion block 20, and a vertical rod 22 is fixedly connected to the bottom of the side panel 21, and the bottom end of the vertical rod 22 passes through the top of the fixed cover 10, and a first spring 23 is fixedly connected to the bottom of the side panel 21 and around the surface of the vertical rod 22.

[0043] The extrusion block 20 and the vertical rod 22 both penetrate the top of the fixed cover 10 and can enter the inner side of the fixed cover 10 by moving up and down.

[0044] When the thickness of the metal part is less than the height of the sliding plate 35, the fixed cover 10 cannot squeeze and fix the metal part. At this time, the telescopic end of the electric telescopic rod 16 extends to drive the squeezing plate 19 to squeeze the fixed cover 10. When the fixed cover 10 is completely in contact with the top of the sliding plate 35, the fixed cover 10 cannot drop. At this time, the electric telescopic rod 16 continues to extend, and the movable limit block 30 contracts under the huge squeezing force of the fixed limit block 27, so that the fixed limit block 27 passes. At this time, the electric telescopic rod 16 drives the pressure block 26 to continue to descend to squeeze the squeezing block 20. The squeezing block 20 is forced to pass through the fixed cover 10 to squeeze and fix the metal parts on the placement plate 9. Metal parts of different thicknesses can be clamped, which has a wide range of applications and reduces the difficulty of operation.

[0045] A knife-edge plate 33 is fixedly connected to one side of the placement plate 9 , and a sliding groove 34 is fixedly connected to one side of the knife-edge plate 33 .

[0046] The blade plate 33 is located directly below the blade 6. After the blade 6 cuts the metal parts, it will continue to fall due to inertia. Therefore, the blade plate 33 is provided with a U-shaped groove to dock the blade 6, so as to prevent the blade 6 from continuing to fall due to inertia and damaging the device, thereby increasing the service life of the device.

[0047] The material slide trough 34 is cut obliquely to prevent the waste materials after cutting from accumulating in the trough and affecting the subsequent cutting. The oblique setting allows the cut waste materials to slide directly, which is simple to operate and saves time.

[0048] The top and bottom of the circuit rod 15 are movably connected with a button 31 for controlling the switch of the electric telescopic rod 16, and the surface of the body 4 is fixedly connected with a toggle rod 32. When the blade 6 is adjusted for cutting, the toggle rod 32 contacts the button 31 during the movement of the random body 4.

[0049] A circuit connecting the button 31 and the electric telescopic rod 16 is provided in the circuit rod 15. The toggle rod 32 is made of rubber and has a relatively soft texture. After pressing the button 31, it is squeezed under the circuit rod 15. When the cutting is completed and the blade 6 is raised, the toggle rod 32 will press the button 31 at the bottom of the circuit rod 15 to retract the electric telescopic rod 16.

[0050] Working principle:

[0051] Metal parts placement and initial fixation

[0052] The metal parts to be cut are placed on the placement plate 9, the bottom of the placement plate 9 is fixed to the base 1 through the pad 8, the extension and retraction ends of the hydraulic cylinders 25 on both sides of the top of the placement plate 9 are in contact with the sliding plate 35, the hydraulic cylinder 25 is started, and the hydraulic cylinder 25 drives the sliding plate 35 to clamp the metal parts in the left and right directions to prevent the metal parts from shifting left and right.

[0053] Further fixing of metal parts

[0054] The fixing cover 10 is located directly above the placement plate 9 and can be moved in the vertical direction to adjust the clamping distance between the fixing cover 10 and the placement plate 9. When the metal parts are placed, the fixing cover 10 moves downward to squeeze and fix the metal parts in the vertical direction to prevent the metal parts from shaking up and down.

[0055] If the thickness of the metal part is less than the height of the sliding plate 35, and the fixed cover 10 cannot directly squeeze and fix the metal part, the T-shaped slider 12 at the bottom of the moving block 11 on one side of the base 1 slides in the T-shaped slide groove 13 at the top of the base 1, and the support rod 14, circuit rod 15 and electric telescopic rod 16 at the top of the moving block 11 move accordingly, and the telescopic end of the electric telescopic rod 16 extends to drive the ring 17 and the extrusion plate 19 connected thereto to squeeze the fixed cover 10. When the fixed cover 10 is completely fitted with the top of the sliding plate 35, the electric telescopic rod 16 continues to extend, and through the interaction of the internal structure of the ring 17 (the fixed limit block 27, the movable limit block 30, the second spring 29, etc. are described in detail in the above embodiments), the electric telescopic rod 16 drives the pressure block 26 to continue to descend, and the pressure block 26 squeezes the extrusion block 20 at the top of the fixed cover 10, and the extrusion block 20 is forced to pass through the fixed cover 10 to squeeze and fix the metal parts on the placement plate 9.

[0056] Cutting operation

[0057] Hold the handle 7 and turn the machine body 4 so that the blade 6 is aligned with the metal part for cutting. When the blade 6 is adjusted for cutting, the toggle rod 32 on the surface of the machine body 4 contacts the button 31 on the circuit rod 15 during the movement of the machine body 4, and the switch of the electric telescopic rod 16 can be controlled. The waste generated by cutting is discharged through the sliding groove 34 on one side of the placement plate 9.
