Description

Technical Field

[0001] This invention relates to the field of door and window processing equipment technology, and in particular to a cutting device for door and window processing. Background Technology

[0002] In the manufacturing process of doors and windows, the precise cutting of profiles is a key process that determines the final quality and assembly accuracy of the product. Currently, the cutting equipment commonly used in the industry is gradually revealing several structural deficiencies when dealing with complex processing requirements. These deficiencies do not exist in isolation, but are interconnected and have a chain reaction throughout the entire process.

[0003] Traditional cutting equipment requires repeated manual clamping and adjustment of the cutting components when performing bidirectional or complex angle cuts. This process is cumbersome and lacks repeatability and positioning accuracy. Even with the introduction of lifting and telescopic mechanisms in some equipment, the cantilever structure, lacking effective external rigid support, is prone to slight vibrations or elastic deformation under the cutting reaction force when extending for cutting. If the clamping position of the profile cannot maintain precise vertical alignment with the cutting component after the cutting component has been adjusted, the point of application of the cutting force will deviate from the predetermined position, further aggravating the vibration of the cutting component. Furthermore, clamping methods that push the profile to one side by applying force on one side are prone to uneven force distribution and skewing. The superposition of this clamping force and the cutting force can cause irregular deformation of the profile, ultimately affecting cutting accuracy and yield. Summary of the Invention

[0004] To address the shortcomings mentioned above, this invention provides a cutting device for door and window processing. In the profile clamping and positioning stage, the clamping structure achieves non-skewed centering and fixing of the profile through a two-step clamping process of internal support centering and external pressure locking. In the posture adjustment and rigidity locking stage of the cutting component, the adjustment structure constructs a rigid closed loop that resists cutting impact through active driving and passive solidification.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. This invention achieves mechanical parallel connection between the passively lockable telescopic column assembly in the limiting structure and the actively driven lifting structure. This not only allows the position of the cutting structure to be effectively adjusted, but also enables the cutting reaction force at the end of the cantilever cutting head to be instantly transferred and borne by the whole frame through the rigid closed-loop support structure, thus completely eliminating the source of elastic vibration and ensuring high precision of cutting dimensions and smoothness of the cross-section.

[0017] 2. This invention solves the problems of profile skewing and uneven force caused by unilateral force application by introducing a clamping process that first internally supports and positions the profile, and then simultaneously externally presses and locks it by electric telescopic rods on both sides. The internal support force and external pressure in the clamping structure form a balanced couple on the same plane, which eliminates irregular deformation of the profile and ensures precise alignment of the profile to be cut with the upper cutting structure in space, thus ensuring the cutting accuracy from the material end.

[0018] 3. This invention adopts a top-center bidirectional symmetrical air inlet layout, which creates a covering capture flow field that closely follows the dust source, thus curbing dust diffusion at the source. At the same time, through multi-point and multi-directional vibration excitation, it actively disrupts the accumulation of debris, achieving smooth flow and compaction collection of waste materials. This completely eliminates the tedious manual cleaning of the guide channel, ensuring continuous and efficient operation of the equipment and significantly reducing maintenance costs.

[0042] In this embodiment, the clamping structure includes a first clamping structure and a second clamping structure respectively disposed on the left and right sides of the top of the workbench 2. The two are respectively disposed in the vertical direction corresponding to the first cutting structure and the second cutting structure to ensure that the cutting force can be accurately applied to the preset position to be cut of the profile.

[0043] In this embodiment, taking the first clamping structure located on the left as an example, the specific operation process is as follows: After the operator places one or two sets of door and window profiles to be cut horizontally in the corresponding positions of the first clamping seat, the first bidirectional telescopic rod located in the center is activated first. The two ends of the first bidirectional telescopic rod extend outward simultaneously, and the first positioning clamping plate installed at the left end and the second positioning clamping plate installed at the right end respectively stably abut against the left and right side walls of the profile. Since the two thrusts applied outward from the center position by the first bidirectional telescopic rod are equal in magnitude and opposite in direction, the profile will be naturally pushed to the corresponding position at the instant it is subjected to these two symmetrical forces, completing the precise pre-positioning. The above action fundamentally avoids the initial deflection of the profile due to uneven force in the traditional single-sided push-and-position method. Immediately following, the first electric telescopic rod at the left end and the second electric telescopic rod at the right end of the first clamping seat extend inward simultaneously. The first electric telescopic rod drives the first clamping plate at its right end to press against the left outer wall of the profile, forming a pair of balanced force couples with the first positioning clamping plate at the same point on the right side wall of the profile. At the same time, the second electric telescopic rod drives the second clamping plate at its left end to press against the right outer wall of the profile, forming another pair of balanced force couples with the second positioning clamping plate at the same point on the right side wall of the profile. Since the inner and outer clamping forces cancel each other out in the same plane, the profile is firmly locked without being subjected to any net torque that would cause it to bend or twist, thus being precisely fixed in an ideal state without stress deformation. At this time, the position to be cut at the top of the profile is precisely vertically aligned with the spatial position of the first cutting structure above.

[0044] In this embodiment, after the clamping process is completed, the spatial position of the cutting structure needs to be adjusted so that it can be moved precisely to the cutting starting point of the profile. The adjustment structure includes a first adjustment structure and a second adjustment structure symmetrically arranged on the left and right sides inside the housing. The adjustment structure is composed of three parts: a limiting structure, a lifting structure, and a telescopic structure.

[0045] Taking the first adjustment structure on the left as an example, its workflow is as follows:

[0046] First, the first lifting hydraulic cylinder in the first lifting structure is activated. The hydraulic pressure inside pushes the piston rod, which transmits the thrust to the first lifting connecting seat via the first lifting rod. Under the precise guidance of the first lifting slide rail pre-set on the inner wall of the left side of the housing, the first lifting connecting seat drives the first telescopic structure and the cutting structure connected to its right side to move smoothly up and down until the preset cutting height is reached. During this lifting process, the first limiting structure consists of the first limiting mounting seat, the first limiting support seat, the first lower limiting telescopic column, the first limiting seat, the first upper limiting telescopic column, and the first limiting connecting seat, connected sequentially from bottom to top. The first limiting connecting seat is fixed to the left end of the first lifting connecting seat by the first limiting connecting rod. When the first lifting connecting seat slides up and down, the first upper limiting telescopic column and the first lower limiting telescopic column are dynamically stretched or compressed. They always elastically bridge the first lifting connecting seat with the first limiting mounting seat fixed at the bottom of the housing, so that the entire kinematic chain always maintains a retractable rigid connection state. Next, the first telescopic electric cylinder of the first telescopic structure is activated. The precision lead screw inside it accurately converts the rotational motion of the motor into the linear motion of the first telescopic rod, pushing the first telescopic connecting seat to smoothly extend to the right with the cutting structure installed at its end, so that the cutting tool accurately reaches the position to be cut on the left side of the profile, thereby completing the posture switch of the equipment.

[0047] When the cutting structure operates at high speed and performs heavy cutting on the profile, the huge cutting reaction force and impact load will attempt to cause the first telescopic connecting seat, which is in a cantilevered state, to warp upward or deflect backward. This unstable load is transmitted through the first telescopic mounting seat to the first lifting connecting seat, and then through the first limiting connecting rod to the first limiting connecting seat. At this time, the first upper limit telescopic column and the first lower limit telescopic column, which constitute the limiting structure, will immediately enter hydraulic or mechanical locking under tension or compression, locking their instantaneous length. This allows the impact load to be directly transmitted and dissipated to the entire machine frame composed of the worktable and the housing through the shortest straight path, forming an instantaneously solidified rigid closed-loop force transmission path. This eliminates the elastic deformation space at the end of the cantilever cutting assembly, fundamentally solving the problem of accuracy loss caused by cutting vibration.

[0048] In this embodiment, at the same time the cutting operation is started, the logic circuit of the control system interlocks and opens the exhaust structure, which includes an air inlet box, an air inlet, an exhaust filter box, and an exhaust fan.

[0049] The high-speed rotation of the first and second exhaust fans generates a powerful suction force, creating a stable negative pressure environment in the air intake box located at the center of the top of the housing. Since the air intake includes several first air intakes evenly distributed on the upper side of the air intake box and several second air intakes evenly distributed on the lower side of the air intake box, and the two are arranged in a parallel structure, the vertically opposed suction layout directly covers the top and bottom of the contact point between the cutting tool and the profile with the negative pressure capture area.

[0050] When the debris and dust generated from cutting are splashed at high speed at different angles, especially the fine dust that diffuses upwards, it will be directly captured and sucked in by the downward airflow at several second air inlets along its flying path. Meanwhile, the large debris falling downwards from the cutting point is guided by the negative pressure flow below, forming a three-dimensional enveloping airflow capture field in the space where it is most easily diffused, thus eliminating the airflow dead zone problem that exists in the traditional single-sided exhaust layout.

[0051] After the polluted airflow carrying dust and debris enters the intake box, it is automatically diverted according to the airflow path, entering the first and second exhaust filter boxes arranged side by side. In the first exhaust filter box, large debris settles under the influence of gravity and the centrifugal effect generated by the airflow turning, falling into the first dust outlet at its bottom. The fine dust remaining in the airflow is effectively intercepted by the first exhaust filter screen inside the box. The clean air after high-efficiency filtration is then discharged to the external environment by the first exhaust fan. The working process of the second exhaust filter box is the same as that of the first exhaust filter box: coarse debris falls into the second dust outlet, dust is intercepted by the second exhaust filter screen, and clean air is discharged by the second exhaust fan. This dual-channel parallel layout not only multiplies the filtration area and reduces the wind resistance and energy consumption of a single channel, but also allows the other channel to maintain full power operation while one channel is cleaning its dust outlet or replacing its filter screen, ensuring uninterrupted continuous production and significantly improving the practicality and production efficiency of the equipment.

[0052] In this embodiment, most of the chips generated during the cutting process fall downward into the pre-set recovery structure inside the worktable under the action of gravity and airflow. The recovery structure includes a first recovery structure corresponding to the first clamping seat and a second recovery structure corresponding to the second clamping seat.

[0053] Taking the first recycling structure on the left as an example: the falling waste first comes into contact with the first guiding assembly, which consists of the first left guide plate, which is inclined from left to right and the first right guide plate, which is inclined from left to right. Together, they form a funnel-shaped material guiding structure with a narrow bottom, which gathers the falling debris into the first recycling box in the middle.

[0054] This invention features a first vibrator at the left end of the first recycling bin, and a first vibration connecting rod arranged in a three-dimensional spatial distribution to efficiently transmit vibrational energy to areas prone to blockage. The top of the first upper vibration connecting rod is connected to the bottom of the first left guide plate, directly applying high-frequency vibration to the surface of the guide plate. When irregularly shaped debris hooks onto the inclined surface of the first left guide plate and attempts to form a blockage, the high-frequency vibration of the plate continuously disrupts the newly formed blockage between the debris particles, causing the accumulated debris to disintegrate and continue to slide down before forming a stable structure. Simultaneously, the right end of the first right vibration connecting rod is connected to the left end of the first recycling bin, directly transmitting vibrational energy to the side wall of the bin, vibrating and compacting the debris that has fallen into the bin, squeezing out the gaps between the debris, significantly improving the effective volume utilization rate of the recycling bin, and reducing the frequency of bin cleaning.

[0055] The second recycling structure on the right works on the same principle. The second vibrator transmits vibration to the bottom of the second right guide plate through the second upper vibrating connecting rod to break up arches, and transmits vibration to the body of the second recycling box through the second left vibrating connecting rod for compaction. Through this coordinated process, the equipment achieves unblocked, intervention-free automatic collection of waste materials, completely eliminating the tedious labor of manually cleaning the guide groove and ensuring smooth operation of long-term continuous cutting operations.

[0056] In this embodiment, throughout the entire workflow described above, the limiting structure is used to limit the lifting amplitude of the lifting structure in real time, ensuring that it always operates within a safe travel range; the lifting structure is used to precisely adjust the vertical processing height of the cutting structure; and the telescopic structure is used to precisely adjust the horizontal feed position of the cutting structure. The collaboration of these three structures ultimately ensures that the cutting structure can maintain a precise vertical correspondence with the profile that has been centered and fixed in the clamping structure below when performing cutting, thereby precisely applying the cutting force to the preset position and ensuring processing accuracy.

The specific connection and control sequence, and the sequential operation order between each electrical component to complete the electrical connection, are well-known technologies in the field, and will not be described further regarding electrical control.
