Description

Technical Field

[0001] This utility model belongs to the technical field of profile cutting equipment, and in particular relates to a plastic door and window profile cutting device. Background Technology

[0002] Cutting plastic door and window profiles is a key process in the manufacturing of plastic doors and windows. It refers to the process of using specialized equipment (mainly a double-headed cutting saw) to precisely cut the extruded plastic door and window profiles to the required length according to the design dimensions and angle requirements.

[0003] Currently, although plastic is not very hard, it is brittle. When the blade cuts through the end face, it can easily tear or chip off a small piece of the profile edge, which seriously affects the welding quality and appearance.

[0004] To address the aforementioned problems, this application proposes a plastic door and window profile cutting device. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic door and window profile cutting device, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a plastic door and window profile cutting device, including a frame and its internal clamps and blades, wherein the frame has a positioning groove corresponding to the blades;

[0008] The blade is provided with clamping plates on both sides, distributed on the outer sides of the profile. A secondary plate is movably installed between adjacent clamping plates, located inside the profile. The clamping plates and secondary plates are close to each other to clamp the formed edge. Buffer pads are installed on both sides of the clamping plates and secondary plates.

[0009] Preferably, a fixing frame is fixed above the frame and distributed on both sides of the clamp, and a bracket extends from the upper end of the fixing frame toward the blade side.

[0010] Preferably, a transmission rod is rotatably mounted inside one end of the bracket, and two parallel guide rods are fixed inside the other end of the bracket.

[0011] Preferably, the upper end of the clamping plate has a protruding plate, and the protruding plate has a transmission hole for connection inside.

[0012] Preferably, the upper ends of both the clamping plate and the sub-plate have a crossbeam extending away from the blade, and the crossbeam has a positioning hole that is slidably connected to the guide rod inside.

[0013] Preferably, bidirectional electric telescopic devices are installed between the clamping plate and the sub-plate, as well as between adjacent sub-plates, located on the upper two surfaces near the blade.

[0014] Preferably, a transmission mechanism for driving the transmission rod to rotate is installed on the outer side of the upper end of the bracket.

[0015] This utility model has the following beneficial effects:

[0016] This utility model uses adjacent clamping plates and sub-plates to clamp the edges of the profile, which can hold the two sides of each edge during the cutting operation, thereby forming a limiting force to prevent chipping due to the advancement of the blade, and ensuring the structural integrity and aesthetic appearance of the profile after cutting.

[0017] Furthermore, the convex plates laid on the surfaces of the clamping plate and the sub-plate can form a protective barrier when clamping the edge of the profile. This not only avoids the clamping deformation caused by rigid contact, but also provides a certain buffering effect when the blade advances, further enhancing the protection of the profile.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figure 1-4 As shown, this utility model is a plastic door and window profile cutting device, including a frame 11 and a clamp 12 and a blade 13 inside it. The frame 11 has a positioning groove 111 inside it corresponding to the blade 13.

[0030] The blade 13 has clamping plates 14 on both sides, distributed on the outer sides of the profile, for clamping the profile. These plates serve both to position the profile and to limit the deformation of the profile's edge sidewalls. A secondary plate 141 is movably installed between adjacent clamping plates 14, located inside the profile, for combining with the clamping plates 14 to clamp the inner edge sidewalls of the profile. Both sides of the clamping plates 14 and the secondary plate 141 are equipped with buffer pads 1404, which protect the profile from rigid contact damage caused by the clamping of the clamping plates 14 and the secondary plate 141, and also buffer the edge sidewalls formed during cutting, further preventing the problem of chipping.

[0031] Furthermore, a fixed frame 15 is fixedly installed on the upper part of the frame 11, distributed on both sides of the clamp 12. The clamp plate 14 and the sub-plate 141 are located between the adjacent fixed frames 15. The upper end of the fixed frame 15 extends towards the blade 13 with a bracket 151. A transmission mechanism is installed on the outer side of the two brackets 151, and the transmission mechanism has a built-in micro rotary motor.

[0032] Furthermore, a transmission rod 1511 is rotatably mounted inside one end of the bracket 151. It is driven to rotate by a micro rotary motor. The two ends of the transmission rod 1511 rotate in opposite directions and are connected to the transmission hole 14031 in the upper protrusion 1403 of the clamping plate 14. The transmission rod 1511 is a ball screw. When the transmission rod 1511 rotates, the two clamping plates 14 can be driven to move in opposite directions at the same time through the structure of opposite rotation, moving closer or further away from each other, so as to automatically center the profile.

[0033] Furthermore, two parallel guide rods 1512 with smooth surfaces are fixed inside the other end of the bracket 151. The upper ends of the clamping plate 14 and the sub-plate 141 both extend a crossbeam 1401 away from the blade 13. The crossbeam 1401 has a positioning hole 14011 inside that is slidably connected to the guide rods 1512, which is used to fix the movement path of the clamping plate 14 and the sub-plate 141, preventing deviation while ensuring that the movement of the clamping plate 14 is smooth.

[0034] Furthermore, bidirectional electric telescopic devices 1402 are installed between the clamping plate 14 and the sub-plate 141, as well as between adjacent sub-plates 141. These devices are located on the upper two surfaces near the blade 13. After the two clamping plates 14 are aligned with the profile, the bidirectional electric telescopic devices 1402 drive the sub-plates 141 to abut against the two sides of the inner sidewall of the profile, thereby forming a clamping effect.

[0035] It is understood that this utility model can form a synergistic protection mechanism of limiting and buffering the edge sidewalls of the profile during use, which can not only prevent the profile from chipping at the corners during cutting, but also prevent the profile from deforming, and ensure the structural integrity of the profile after cutting.

[0036] A specific application of the operation process of this embodiment is as follows: In use, firstly, through the transmission hole 14031 and the transmission rod 1511, the two clamping plates 14 are controlled to abut against the outer surfaces of both sides of the profile. Then, the sub-plate 141 is pushed by the bidirectional electric telescopic device 1402, thereby clamping each side of the profile and preventing rigid contact by the buffer pad 1404. At this time, when the profile is cut, the stress-bearing part of its edge is clamped by the clamping plates 14 and the sub-plate 141, and the buffer pad 1404 forms a buffer protection, which can effectively prevent the occurrence of corner chipping, ensure the structural integrity of the profile after cutting, and facilitate subsequent processing and production.
