Description

Cutting method of double-head cutting saw with 45-degree angle for door and window frame profiles

technical field

The invention relates to a sawing device, in particular to a sawing method of a double-head sawing machine for cutting an aluminum profile at a 45-degree angle, and belongs to the technical field of aluminum alloy door and window processing equipment.

Background technique

In the process of door and window processing, the profiles need to be cut into aluminum profiles of different lengths, angles and end shapes that match the size of the doors and windows, and then assembled into doors and windows. When assembling, the ends of the two profiles are in contact, and high-quality doors and windows must be assembled , the length of the profile and the roughness of the end face are very demanding. Among the door and window profiles, the frame and fan profiles consume the largest amount. In order to improve work efficiency and ensure the consistency of the cutting angles at both ends of the aluminum profile, a double-head cutting saw is usually used to cut the aluminum profile, which can realize the two ends of the profile being cut out on one piece of equipment. With a 45-degree inclined surface, two adjacent aluminum profiles are butted to form a 90-degree angle, and finally the corners are processed on the corner forming machine, and the frame profiles are connected into an overall frame structure through corner codes. Figure 1 is a schematic diagram of the broken bridge aluminum alloy door and window frame material, Figure 2 is a schematic diagram of the frame material with both ends cut into 45-degree inclined planes, side a is the window frame installation surface, corresponding to the door/window opening on the building, side b is glass Or the installation surface of the fan, the c surface is the outdoor surface (facing outside the building), the d surface is the indoor surface (facing the interior), the angle between the 45-degree slope and the a surface is 45 degrees, and the angle between the b surface and the b surface is 135 degrees , and the angle between c and d planes is 90 degrees. The main factors affecting the corner quality of door and window groups are the angle accuracy of the 45-degree inclined plane after profile cutting, the perpendicularity between the 45-degree inclined plane and the c and d planes, the length L of the installation surface, and the surface roughness of the 45-degree inclined plane; If the perpendicularity between the inclined plane and the c and d planes is not enough, there will be a gap on the c or d plane after the angle is assembled (see Figure 3), and the length L of the installation surface is not accurate enough (the length of the right frame material is longer than the left frame material length) then there will be two wrong angles after corner assembly (see Figure 4). These defects not only affect the appearance of the finished product but also affect its watertightness and airtightness. Similarly, if the surface state of the 45-degree slope is rough, it will also cause assembly The corner gap is large, which affects the appearance, water tightness and air tightness. The accuracy of the angle of the 45-degree inclined plane is usually fixed by adjusting the working direction of the cutting saw blade and the angle of the horizontal workbench and the vertical workbench when adjusting the initial state of the equipment. The verticality of the 45-degree slope to the c and d planes, the accuracy of the length L of the mounting surface, and the surface condition of the 45-degree slope are affected by factors such as cutting methods.

The working principle and structure of the existing double-head saw are relatively mature, mainly composed of sawing head, bed, support frame, control cabinet and other parts. The double-head saw includes two sawing heads, the left sawing head is a fixed head, and the right sawing head is a movable head, which can move left and right on the guide rail. The structures of the two sawing heads are basically the same, and are generally composed of saw blades, saw blade motors, worktables, and pressing devices. The adjustment is accurate, and then the aluminum profile is placed on the workbench, and the aluminum profile is pressed and fixed by the pressing device; the saw blade motor drives the saw blade to rotate, and the saw blade motor is installed on the motor base and driven by the feed cylinder. The working and feeding motion of the saw blade is realized by means of translation or swing, so as to obtain the required length and end shape of the profile. After the saw blade cuts the profile, a smooth profile cutting end face can be obtained, but when the saw blade returns along the cutting track, due to the slight beating of the saw blade and the vibration of the bed, the saw teeth of the saw blade will collide with the smooth end face of the cut profile. The contact again will cause rough cutting marks on the end surface of the profile. In the industry, it is called sawtooth return sweeping. The return cutting method of returning according to the original sawing track cannot avoid the phenomenon of return sweeping.

The currently used double-head cutting saws have linear feed type and swing feed type according to the working mode of the saw blade, and are divided into swing-out angle type according to the angle between the saw blade and the horizontal table Angle is 135 degrees) and internal swing angle type (the angle between the saw blade and the horizontal table is 45 degrees), the internal swing angle double-headed saw is easy to collapse because the waste head is located on the upper part of the saw blade after sawing. It is pointed out that if the waste clamping device is not added, it will easily lead to safety accidents. Therefore, its application is limited. Patent CN106799518B discloses a double-head cutting saw machine for cutting aluminum profiles at a 45-degree angle, including fixed heads and movable heads. Machine head, support frame (20) is installed on the movable machine head (5), and horizontal workbench (21) and vertical workbench (22) are fixed on the support stand (20), and horizontal workbench (21) is installed with The saw blade (23), the saw blade (23) is installed on the sawing motor (24), the sawing motor (24) is fixed on the slide seat (25), and the slide seat (25) is installed on the slide rail (26 ), the sliding seat (25) is connected with the working air cylinder (27). What this patent adopts is the technical scheme of pendulum angle type + linear feed type.

At present, the swing-out angle double-head cutting saw is widely used, such as the swing-out automatic double-head saw disclosed in the patent CN210817585U, the right machine head (14) and the left machine head (15) are connected with a rotating box (1) , and one side of the rotating box (1) is horizontally equipped with a processing platform, and two hydraulic cylinders (11) are installed vertically and horizontally on the processing platform, and two hydraulic cylinders (11) are installed on the same side of the rotating box (1). The vertical pneumatic clamps (5) and the side pneumatic clamps (6) connected to the oil cylinders (11) respectively, a gas-liquid conversion cylinder (10) is installed in the upper end of the same side of the rotating box (1), and the gas-liquid conversion cylinder (10 ) is connected with a sawing motor swing arm mechanism (2), the sawing motor swing arm mechanism (2) is fixedly connected with a direct-coupled precision cutting motor (8), and the direct-coupled precision cutting motor (8) is A saw blade (13) is installed. What this patent adopts is the technical solution of swing out angle type + swing feed type.

In the prior art, no matter it is the swing-out angle type, the inside-swing angle type, the linear feed type and the swing feed type, the working direction of the saw blade is perpendicular to the vertical workbench, and the vertical workbench is provided with a saw blade. Incision: The profile to be cut is pressed tightly on the horizontal workbench and the vertical workbench. When the saw blade is working, the saw blade protrudes from the saw kerf to cut the profile. In this way, when the saw blade is of a swing-out angle structure, if you want to obtain the frame material shown in Figure 2, you must attach the c-side of the profile to the vertical workbench when cutting, with the a-side on the top and the b-side on the bottom cutting; the cutting length on the double-head cutting saw is usually set by the distance between the two saw blades and the intersection point of the plane on the horizontal workbench, which is expressed as the length L1 of the profile in Figure 2, and the length of the profile required for actual installation is L. The reason is that firstly, the size of the opening of the wall conforms to the L dimension; secondly, the L dimension of the finished product is convenient to measure. Therefore, when determining the frame length L of the 45-angle profile, the material height B of the profile must be included, that is, L=L1+2B, which requires measuring the material height of the profile before cutting the profile. Manual measurement is easy to cause Relatively large measurement error. The error value of material height measurement directly affects the length accuracy of profile cutting, and the length accuracy of cutting profile directly affects the quality of doors and windows. For this reason, someone has designed material high automatic measuring device, as the disclosed aluminum type material height measuring device of patent CN210818749U, adopts magnetic grating ruler to measure material height, has avoided manual measurement error. However, whether it is measured manually or with an automatic measuring device, the cutting efficiency will be reduced.

It can also be seen from Figure 2 that there is an overlapping surface in contact with the fan extending from the c-surface of the profile towards the side of the b-surface. When the profile is placed on the workbench for cutting, only the side of the overlapping surface and the horizontal Table contact, when the vertical pressing device presses the surface a from top to bottom, it is difficult to press the profile on the horizontal workbench, and it is easy to slip when cutting the profile, resulting in positional deviation, resulting in cutting accuracy (angle accuracy, verticality accuracy) and surface roughness), if the vertical pressing device exerts too much force, it will easily lead to deformation of the profile.

In addition, the shortest length of the finished material that can be processed by the existing double-head cutting saw is the length corresponding to the distance between the two saw blades when the right sawing head is adjusted to the closest to the left sawing head. Out of ultra-short material.

To put it simply, at present, the basic feature of the double-head cutting saw for aluminum door and window profiles is that the fixed head and the movable head are mainly swinging out, and the movable head can automatically move at a fixed length, and finally process a given length and a given Workpiece with face angle value. In the aluminum door and window industry, this CNC double-head cutting saw is widely used for profile blanking. However, there are still the following problems: 1. The profile to be cut is not firmly pressed, and it is easy to slip and cause a position shift, resulting in a decrease in cutting accuracy; 2. It is necessary to measure the height of the material before cutting to reduce the cutting efficiency; 3. The saw blade cuts the profile Then return according to the original sawing track, and the return sweep will cause the profile cutting end surface to be rough; 4. Ultra-short materials cannot be cut.

With the improvement of people's living standards and the requirements of national energy conservation and emission reduction policies, the quality requirements for doors and windows are getting higher and higher. The cutting accuracy (angle accuracy, verticality accuracy and surface roughness) of existing equipment can no longer meet the requirements of high-quality doors and windows.

Since the saw blade is perpendicular to the horizontal workbench and the angle between the saw blade and the vertical workbench is 45 degrees, if the installation surface of the frame material profile (face a in Figure 2) is placed on the vertical workbench, the profile will be cut at two ends. The cutting length on the saw is the frame length of the profile, and there is no need to measure the material height of the profile before cutting, and the cutting efficiency and cutting accuracy are improved. And if the installation surface of the frame material profile is leaned against the vertical workbench, the outer or inner surface of the profile will be attached to the horizontal workbench, and the bonding area of the profile, the horizontal workbench and the vertical workbench will be larger.
