Description

Technical Field

[0001] The invention relates to the technical field of profile cutting, and in particular to a processing center for automatically cutting a single aluminum-plastic profile of a door or window at an angle of 45 degrees. Background Art

[0002] With the development of society, labor costs are getting higher and higher, and the door and window industry has higher and higher requirements for the automation and cutting efficiency of profile cutting. In recent years, various profile processing centers have also appeared one after another, which can be generally divided into the following types:

[0003] 1. The saw blade is suspended and driven by a cylinder to rotate at an angle of plus or minus 45 degrees and 90 degrees. When cutting, the saw blade cuts the profile from top to bottom. This cutting method has low cutting efficiency. At the same time, due to the continuous swinging of the angle, the accuracy of the angle is not very stable. At the same time, a large number of cutting burrs will appear on the profile, and the appearance is not beautiful.

[0004] 2. The saw blade is placed at the bottom, and two symmetrical 45-degree saw heads are set. When cutting, the saw blade moves from bottom to top, either by pushing horizontally or by swinging the arm. This cutting method can improve the cutting efficiency and angle stability to a certain extent. However, when cutting, the saw blade mounting assembly is subjected to obvious distortion force, and the cutting quality is greatly affected by the stability of the working slide and guide rail. When used for a long time, the cutting accuracy cannot be guaranteed. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a processing center for automatically cutting a single aluminum-plastic profile for doors and windows at a 45-degree angle. Two symmetrical 45-degree sawing heads are used to cut horizontally forward, thereby ensuring the cutting stability and cutting quality of the aluminum-plastic profile.

[0006] The present invention is achieved through the following technical solutions:

[0011] Further, the clamping assembly includes oblique vertical clamping and a first horizontal clamping;

[0012] The oblique vertical pressing comprises an oblique pressing cylinder, an oblique guide plate and an oblique vertical pressing block arranged along the length direction of the first guide groove, the oblique pressing cylinder is fixed on the positioning plate, the oblique guide plate and the positioning plate are slidably connected through a slide rail and a slideway, and the oblique guide plate is respectively fixed to the piston rod of the oblique pressing cylinder and the oblique vertical pressing block;

In order to adapt to profiles of different heights, its upper and lower positions can be adjusted through long slots. The oblique guide plate and the positioning plate are slidably connected through the slide rails and the sliders. Under the action of the clamping cylinder, the oblique vertical clamping block is pressed at a position very close to the saw cut along the 45° direction of the first saw blade. At the same time, the horizontal clamping block is used to clamp the aluminum-plastic profile using the horizontal cylinder action, which can effectively reduce the vibration of the profile during cutting.

[0015] Preferably, the horizontal pressing block is provided with an inclined surface parallel to the first saw blade plane and capable of pressing to the saw cut position on the plane opposite to the first saw blade; and a pressing shaft is vertically spaced apart on the plane opposite to the aluminum-plastic profile.

[0016] The inclined surface of the horizontal clamping block is designed with a large chamfer of 45 degrees, which can be clamped to the sawing position of the first saw blade to ensure the stability of the profile. A pressure shaft design is added to the horizontal clamping block to minimize friction when the profile is warped upward and the upper pressure is pressed downward to straighten it.

[0019] Furthermore, the machining center also includes a feeding mechanism arranged at the feeding end of the cutting mechanism and controlled by the control console.

[0020] The feeding mechanism includes a feeding rack, on which lifting feeding rollers are arranged along the feeding direction, and an auxiliary clamp for clamping the aluminum-plastic profile and dragging it to the feeding position is installed at one end of the feeding rack away from the cutting mechanism;

[0021] The feeding rack is also equipped with a feeding robot on one side of the auxiliary fixture, which can grab the aluminum-plastic profile at the feeding position and send it to the cutting mechanism. The feeding robot is connected to the feeding rack through a three-axis CNC mechanism. The feeding robot is arranged in the X direction of the three-axis CNC mechanism and is parallel to the feeding direction. The three-axis CNC mechanism is slidably connected to the feeding slide rail on the feeding rack through a slide seat and is driven to move along the feeding direction by a driving device.

[0022] The feeding mechanism lifts the aluminum-plastic profiles through the feeding rollers and cooperates with the auxiliary clamps to deliver the aluminum-plastic profiles to the feeding robot. The feeding robot adjusts the position and grasps the aluminum-plastic profiles through the three-axis CNC mechanism, and drives the aluminum-plastic profiles along the feeding direction to the cutting mechanism through the drive device.

[0023] Furthermore, the auxiliary fixture includes a lifting and lowering mounting plate, and a clamping and dragging material platform located above the mounting plate and slidably connected to the mounting plate in the feeding direction;

[0025] During operation, the mounting plate is pushed by the cylinder to lift the fixture as a whole to the upper plane, the clamping cylinder is activated, and the profile is pressed onto the limit plate by the pressing block. The limit plate is covered with embossing to increase the friction when the profile is dragged. Then the dragging cylinder is activated to drag the clamping and dragging platform holding the aluminum-plastic profile to the mobile material-retrieving mechanism, and the auxiliary fixture opens, retreats, and descends to the initial position.

[0026] Furthermore, the feeding robot is connected to the three-axis CNC mechanism through a fixed arm. The feeding robot includes a support arm, a first clamping end fixed at one end of the support arm, and a second clamping end rotated at one end of the support arm and cooperating with the first clamping end. The second clamping end is connected to a cylinder through a connecting rod mechanism, and the cylinder is fixedly connected to the fixed arm through a mounting seat.

[0027] The second clamping end of the feeding robot can be rotated by the driving device in cooperation with the connecting rod mechanism, and then cooperate with the first clamping end to achieve clamping and loosening, so as to clamp and release the aluminum-plastic profile.

[0028] Furthermore, the feeding roller includes a first feeding roller and a second feeding roller which are arranged at an interval, and the first feeding roller and the second feeding roller are both connected to the lifting cylinder through a support plate, and the first feeding roller and the second feeding roller are respectively provided with positioning rollers on the support plate for preventing the aluminum-plastic profile from falling, and the second feeding roller is also slidably connected with a pressure roller which can cooperate with the positioning roller to limit the profile through a slide rail and a slider on the support plate on the opposite side of the positioning roller, and the pressure roller is fixed on the slider and driven by a pressure roller cylinder fixed on the support plate.

[0029] When the aluminum-plastic profile runs to the material-taking mechanism, the first feeding roller and the second feeding roller are pushed upward by the lifting cylinder to separate the aluminum-plastic profile from the synchronous conveyor belt. The clamping roller on the second feeding roller, under the action of the clamping cylinder, presses the aluminum-plastic profile between the clamping roller and the positioning roller of the first feeding roller.

[0031] The support roller on the unloading rack is used to receive the finished material. The push cylinder is used to push or pull the fixed seat to slide on the unloading rack, so that the push plate pushes the finished material off the support roller and drops it onto the synchronous conveyor belt for collection.

[0032] Furthermore, the machining center also includes a material storage mechanism arranged on one side of the feeding mechanism and controlled by a control console, the material storage mechanism includes a material storage rack, on which are installed a plurality of synchronous conveyor belts arranged at intervals and driven by a motor along a vertical discharge direction, each synchronous conveyor belt having nylon blocks at equal intervals, and the material storage rack is provided with a profile in-place detection switch at the end of the synchronous conveyor belt which is electrically connected to the control console.

[0033] The storage mechanism is used to store the aluminum-plastic profiles to be cut. Each profile is transported to the feeding mechanism by a synchronous conveyor belt. During operation, the profile position detection switch is used to detect the profile position. When the switch is triggered, the drive motor stops and the profile is taken away by the feeding mechanism to realize automatic loading.

[0034] Beneficial effects of the present invention:

[0035] Through the control of the controller, the machining center can realize functions such as automatic loading, automatic cutting, automatic unloading, and automatic collection of waste heads. The cutting mechanism uses two symmetrical 45-degree sawing heads, and the working feed method uses a square rail slider. The cutting method of horizontally pushing the knife out ensures cutting stability and improves cutting quality. It can effectively avoid mechanical clearance and reduce the requirements for system rigidity. The cutting mechanism is equipped with an oblique vertical clamping and a first horizontal clamping match at the first saw blade, which can press the aluminum-plastic profile in a position very close to the saw cut along the 45-degree direction, effectively reducing the vibration of the profile during cutting. The clamping structure at various locations of the machining center uses square rails and slide guides to ensure the stability of the clamping and effectively avoid mechanical clearance.

DETAILED DESCRIPTION

[0057] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0058] A processing center for automatically cutting single aluminum-plastic profiles for doors and windows at a 45-degree angle. The equipment can realize functions such as automatic loading, automatic cutting, automatic unloading, and automatic collection of waste heads through a control console 6, and comprises a storage mechanism 1, a feeding mechanism 2, a cutting mechanism 3, a material taking mechanism 4, and a material unloading mechanism 5 which are arranged in sequence.

[0059] The storage mechanism 1 is used to place multiple profiles to be cut, usually 6-8 pieces; the feeding mechanism 2 is responsible for feeding each profile into the cutting part in sequence according to the length listed in the form; the cutting mechanism 3 is used to cut the profile at 45 degrees; the material taking mechanism 4 is to take out each cut profile and place it on the unloading table; the unloading mechanism 5 is used to carry the finished profiles after cutting; the control console 6 is the human-computer dialogue terminal of the equipment, which is used to set the plan form and issue operation instructions.

[0060] like Figure 3 As shown, the material storage mechanism 1 includes a material storage rack 7, on which a plurality of synchronous conveyor belts 10 are installed at intervals along a vertical discharge direction and driven by a motor 13, each synchronous conveyor belt 10 has nylon blocks at equal intervals, and the material storage rack 7 is provided with a profile in-place detection switch electrically connected to the controller at the end of the synchronous conveyor belt 10.

[0061] The storage rack 7 is welded by a thick-walled rectangular tube of 80mm*80mm, and a plurality of L-shaped brackets are installed on it. A standard profile of 40mm*80mm is installed on the storage rack 7, and the two ends of the standard profile are a driving wheel 101 and a driven wheel 105 of a synchronous pulley 11; the driving wheel 101 is uniformly installed on the front side of the equipment and is connected together by a transmission shaft 12; the driven wheel 105 is uniformly installed at the far end of the equipment, and also has a tensioning effect; Figure 4 As shown, the sliding seat 104 can move to the right under the action of the tensioning block 103 to tighten the synchronous belt 10;

[0062] To facilitate transportation, the storage mechanism 1 consists of two parts, left and right, and the power is transmitted through two couplings 14 in the middle; a total of 8 synchronous conveyor belts 10 are set to advance the profiles, and each synchronous conveyor belt 10 is equipped with nylon blocks with equal spacing; it is uniformly driven by a drive motor 13 equipped with a frequency converter, and the speed is adjustable; during operation, the equipment is equipped with a profile in place detection switch, and when the switch is triggered, the drive motor 13 stops and waits for system instructions.

[0063] like Figure 5 As shown, the feeding mechanism 2 is mainly used to feed each profile in sequence according to the length of the form.

[0064] The feeding mechanism 2 includes a feeding frame, on which lifting feeding rollers are arranged along the feeding direction, and an auxiliary clamp 17 for clamping the aluminum-plastic profile and dragging it to the feeding position is installed at one end of the feeding frame away from the cutting mechanism;

[0065] A feeding robot 16 is installed on one side of the auxiliary clamp 17 of the feeding rack, which can grab the aluminum-plastic profile at the feeding position and send it to the cutting mechanism. The feeding robot 16 is connected to the feeding rack through the three-axis CNC mechanism 15. The feeding robot 16 is arranged in the X direction of the three-axis CNC mechanism 15 and is parallel to the feeding direction. The three-axis CNC mechanism 15 is slidably connected to the feeding slide rail 20 on the feeding rack through a slide seat and is driven by a driving device to move along the feeding direction.

[0066] The three-axis CNC mechanism 15 is composed of three mutually perpendicular motion mechanisms in the X, Y, and Z directions, and can move forward and backward, up and down under the control of the system to adjust the position of the feeding robot 16. The text controller can store a certain amount of position information for the system to call; when the corresponding profile is selected, the feeding robot 16 automatically adjusts to the preset position.

[0067] The movement in the X-axis direction is accurately transmitted by the controller according to the processing form. After the profile is transported to the specified position by the storage mechanism 1, all the feeding rollers rise together, lifting the profile off the synchronous conveyor 10, and the auxiliary clamp 17 clamps the profile and drags it to the feeding position. After the feeding manipulator 16 clamps the profile, the auxiliary clamp 17 opens and returns to the standby position.

[0068] in:

[0069] The feeding rollers include a first feeding roller 19 and a second feeding roller 18 which are spaced apart from each other. The first feeding roller 19 and the second feeding roller 18 are connected to the lifting cylinder 21 through a support plate 42, and the first feeding roller 19 and the second feeding roller 18 are respectively provided with a positioning roller 25 on the support plate 42 for preventing the aluminum-plastic profile from falling. The second feeding roller 18 is also slidably connected with a pressure roller 43 which can cooperate with the positioning roller 25 to limit the profile through a slide rail and a slider on the support plate 42 on the opposite side of the positioning roller 25. The pressure roller 43 is fixed on the slider and driven by a pressure roller cylinder 44 fixed on the support plate 42. A fixed bottom plate 32 fixed to the feeding rack is provided below the support plate 42. The piston rod of the lifting cylinder 21 penetrates the fixed bottom plate 32 and is connected to the support plate 42. A guide rod 22 for guiding the support plate 42 is also penetrated between the fixed bottom plate 32 and the feeding rack. Figure 6 As shown, in the present invention, the feeding structure is provided with a total of ten sets of feeding rollers, including five sets of first feeding rollers 19 and five sets of second feeding rollers 18. After the profile is in place, all the feeding rollers are raised to separate the profile from the synchronous conveyor belt 10, ensuring that the feeding mechanism 2 can clamp and feed the profile to the cutting mechanism 3. After the feeding robot 16 starts feeding according to the instruction, it moves horizontally toward the cutting mechanism 3 quickly. When the feeding robot 16 approaches the position of the second feeding roller 18, the pressure roller 43 of the second feeding roller 18 at this location opens and descends to the initial position at the same time to avoid the feeding robot 16. When a profile is completely cut, the feeding robot 16 quickly returns to the origin position, and all feeding rollers and auxiliary clamps 17 are in the initial position and standby, waiting for the next material to be in place.

A clamping cylinder 31 for driving the clamping block 30 is also fixed on the mounting plate 23. Figure 8 As shown, the profile is located on the clamping and dragging platform 29. When the auxiliary clamp 17 is working, the lifting cylinder 21 lifts the auxiliary clamp 17 to the upper plane, the clamping cylinder 31 is actuated, and the clamping block 30 presses the profile onto the limit plate 28. The limit plate 28 is covered with embossing to increase the friction when the profile is dragged; then, the clamping cylinder 31 is actuated to move the profile on the slide rail to the material picking robot 16 and clamp it, and the auxiliary clamp 17 opens and retreats and descends to the initial position.
