Description

Technical Field

[0001] The invention relates to the field of aluminum alloy corner block processing, and in particular to a method for processing a glue injection guide groove of an aluminum alloy corner block and processing equipment thereof. Background Art

[0002] Aluminum alloy corner brackets refer to the corner connectors for aluminum alloy doors, windows and outer frames. They are generally 6-meter-long aluminum alloy corner bracket profiles, which are then cut into corner bracket blocks with matching thickness with the inner cavity of the door and window profiles by an aluminum alloy corner bracket saw, and then the corner bracket work is carried out. With the development of the industry and the continuous improvement of national energy-saving requirements, the industry has gradually improved the corner strength and waterproof and heat-insulating performance after corner bracketing. In order to improve the corner strength and waterproof and heat-insulating performance of the corner bracket position, most high-end door and window factories will process glue injection guide grooves on the 45-degree line on the left and right sides of the aluminum alloy corner bracket (see Figure 1 ), after the corners are assembled, structural adhesive is injected into the corner cavity to improve the waterproof and heat insulation performance of the corners.

[0003] At present, there are several commonly used methods for processing and making guide grooves. The first is to add plastic guide plates on both sides of the corner code to form a guide groove. The main disadvantage is that an isolation layer is formed between the guide plate and the corner code, and the guide plate cannot form a whole with the corner code. When the corner code and the profile are displaced by external force, the injection surface will crack, thereby losing the function of sealing and strengthening the corner strength. The second is to use cast corner codes to directly cast the guide grooves, but the cast corner codes are hardened and fragile. If the extruder is not adjusted properly during the corner assembly process, cracks are likely to occur, thus affecting the corner strength. In addition, this method has low production efficiency and high cost, which greatly increases the cost of doors and windows. The third method is to manually line up the profile corner codes cut by the corner code saw, and then use another sawing machine with a set of saw blades on the top and bottom for secondary cutting, and saw a groove on the top and bottom of the corner code. Although this method solves the disadvantages of the first two methods, the processing process is cumbersome, inefficient, and cannot be produced continuously. Summary of the invention

[0004] The problem to be solved by the present invention is to provide a method and equipment for processing a glue injection guide groove for an aluminum alloy corner bracket, which can process the glue injection guide groove at the same time as the aluminum alloy corner bracket profile is cut and cut, and the corner bracket block does not need secondary processing, thereby realizing continuous production, greatly improving work efficiency, and saving production costs.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] In the description of the invention, it is necessary to understand that the directions or positional relationships indicated by the terms "left", "right", "front", "back", "up", "down", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the invention.

[0038] In order to solve the problems in the background technology, this embodiment discloses a method for processing an aluminum alloy corner guide groove, comprising the following steps:

[0039] Step 1: Place the aluminum alloy corner bracket profile with the top corner facing upward on the working platform in an inverted manner;

[0040] Step 2: Use the drill bit of the drilling equipment to drill holes I and II that penetrate the solid part of the top corner of the aluminum alloy corner bracket profile. The holes I and II are distributed along the length direction of the aluminum alloy corner bracket profile, such as Figure 2 As shown;

[0041] Step 3, using the saw blade of the angle code saw to cut the aluminum alloy angle code profile along the perpendicular midline of the center distance between hole I and hole II to form an angle code block, and forming a semicircular groove on each of the two cut surfaces, the semicircular groove being the glue injection guide groove;

[0042] Step 4, repeat steps 2 and 3, and finally process the aluminum alloy corner bracket profile into a plurality of corner bracket blocks, among which the corner bracket blocks having glue injection guide grooves on both left and right sides are the corner bracket blocks that meet the requirements.

[0043] During the processing, the saw blade thickness of the angle code saw is b, the radius of hole I and hole II is r, the center distance between hole I and hole II is a, and the depth of the injection guide groove is c; the relationship between the various parameters is c=r+(ab) / 2, where b>a-2r. The various parameters described in this implementation can be taken according to the parameters in the following table:

[0044]

[0045] It is worth noting that in step 2, the drill bit of the drilling equipment can also be used to drill only one hole that penetrates the solid part of the top corner of the aluminum alloy angle bracket profile; in step 3, the aluminum alloy angle bracket profile is cut along the diameter of the hole with the saw blade of the angle bracket saw to form an angle bracket block, and a semicircular groove is formed on each of the two cut surfaces, which is the glue injection guide groove. However, in order to ensure that the glue injection guide groove has sufficient depth, two holes need to be drilled.

[0046] like Figure 3As shown, the present embodiment also discloses a processing equipment suitable for the above-mentioned aluminum alloy angle code guide groove processing method, which mainly includes a working platform 1, an angle code saw, a drilling device, a tail clamping mechanism 3 and a feeding clamping mechanism 2. The working platform 1 is extended and distributed along the left and right directions, with the left end as the head and the right end as the tail. Two smooth guide rails 4 are arranged on the working platform 1 along the left and right directions.

[0047] like Figure 5 As shown, the angle code saw includes a sawing head 5 and a sawing platform 6. The sawing head 5 is installed on the sawing platform 6. Since the sawing head 5 is a conventional device for cutting aluminum alloy angle code profiles, it will not be described in detail here. The sawing platform 6 is slidably fitted on the guide rail 4 near the left end through a slider. An adjusting screw rod 7 is rotatably installed on the working platform 1 along the left and right directions, and a nut threadedly connected to the adjusting screw rod 7 is installed at the bottom of the sawing platform 6. By manually rotating the adjusting screw rod 7, the relative position of the angle code saw in the left and right directions can be fine-tuned to match the initial hole sawing position of the glue injection guide groove.

[0048] like Figure 6 As shown, the drilling equipment includes a drilling head 8 and a drilling platform 9. The drilling head 8 is installed on the drilling platform 9. The drilling head 8 is a conventional automated drilling device that can move up and down and forward and backward using a drill head. It will not be described in detail here. The drilling platform 9 is slidably engaged on the guide rail 4 through a slider, and the drilling equipment as a whole is located to the right of the angle code saw.

[0049] like Figure 4 As shown, the feeding clamping mechanism 2 includes two clamping units, one clamping unit is located between the angle code saw and the drilling device, and the other clamping unit is located on the right side of the drilling device; the tail clamping mechanism 3 includes a clamping unit and is fixedly installed at the right end of the working platform 1. Each clamping unit includes a feeding platform 21, a support plate 22, a vertical clamping cylinder 23 and a horizontal clamping cylinder 24. The support plate 22 is vertically fixedly installed at the rear end of the feeding platform 21 to form a right-angle bracket, the horizontal clamping cylinder 24 is installed at the front end of the feeding platform 21, and the vertical clamping cylinder 23 is installed at the top end of the support plate 22. The horizontal clamping cylinder 24 and the vertical clamping cylinder 23 can cooperate with the support plate 22 to clamp the aluminum alloy angle code profile.

[0050] In the feeding and clamping mechanism 2, two feeding platforms 21 are respectively mounted on the guide rail 4 by means of sliding fit of a slider, and the two feeding platforms 21 are fixedly connected as a whole by means of a synchronous connecting shaft 25, so as to ensure that the feeding and clamping mechanism 2 can move left and right synchronously. In the tail clamping mechanism 3, the feeding platform 21 is fixedly mounted on the working platform 1 by means of a bolt assembly.

[0051] Four support racks 10 are installed on the working platform 1 and are located on the right side of the drilling equipment. Driven rollers are provided on the support racks 10 along the front-to-back direction, which can move the aluminum alloy corner code profiles on the stripping racks to reduce friction.

[0052] Since the feeding and clamping mechanism 2 and the drilling equipment need to move accurately left and right on the guide rail 4, a conventional rack and pinion transmission mechanism can be selected as the driving method. A rack is installed on the rear side wall of the working platform 1 along the left and right directions, and a driving motor is respectively provided at the rear of the feeding platform 21 and the drilling platform 9. The output shaft of the driving motor is equipped with a gear that can mesh with the rack for transmission. Because the rack and pinion transmission mechanism belongs to conventional technical means, it is not described in detail here.

[0053] Taking the processing of 2.7 mm deep injection guide grooves on the left and right sides of the corner block as an example, the specific processing process of the processing equipment of the present invention is as follows:

[0054] Step 1: Place the aluminum alloy corner bracket profile with the top corner facing upward on the working platform in an inverted manner, and the two clamping units of the feeding clamping mechanism clamp the aluminum alloy corner bracket profile through the vertical clamping cylinder and the horizontal clamping cylinder;

[0055] Step 2: Use the drill bit of the drilling equipment to drill holes at the top corners of the aluminum alloy corner profile. Figure 2 Drill holes I and II through the solid part of the top angle. Holes I and II are distributed along the length direction of the aluminum alloy corner profile. The radius of holes I and II is 2 mm, and the center distance between holes I and II is 4 mm.

[0056] Step 3, the feeding clamping mechanism moves to the left, so that the part with the processed hole moves to the saw blade position of the angle code saw, the thickness of the saw blade is 2.6mm, and the aluminum alloy angle code profile is cut along the perpendicular line of the center distance of hole I and hole II with the saw blade of the angle code saw to form an angle code block, and a semicircular groove is formed on each of the two cut surfaces. The semicircular groove is the glue injection guide groove, and its depth is 2.7mm;

[0057] When the feeding clamping mechanism finishes feeding forward and moves backward to prepare for the next feeding, the tail clamping mechanism clamps the profile, and the feeding clamping mechanism releases the profile and moves backward, which can ensure that the aluminum alloy corner code profile is fixed and ensure the accuracy of the next feeding;

[0058] Step 4, repeat steps 2 and 3, and finally process the aluminum alloy corner bracket profile into a plurality of corner bracket blocks, among which the corner bracket blocks having glue injection guide grooves on both left and right sides are the corner bracket blocks that meet the requirements.
