Description

Double head saw cutting machine assembly

technical field

The invention relates to a double-head saw, in particular to a double-head saw cutting machine assembly for sawing, for example, aluminum profiles.

Background technique

Profile workpieces often need to be cut at least one end, and generally both ends are cut at the same time. For example, door and window profile workpieces need to be cut at a right angle or a 45-degree angle at both ends. In order to improve the processing speed of profile workpieces, double A head saw cutting machine assembly, the existing double head saw cutting machine assembly includes a frame, and a sliding drive motor, a movable cutting unit, and a linear horizontal rail arranged on the frame; the movable cutting unit is slidably arranged on the linear horizontal rail. Both the stationary cutting unit and the movable cutting unit include a cutting motor, a guide mount, a saw blade mounting shaft, a saw blade bearing, a saw blade, a pulley, a belt, and a cutting that adjusts the distance between the cutting motor and the saw blade bearing to adjust the tension of the belt Motor position adjustment seat; the saw blade bearing is arranged at the front of the guide mounting seat, the cutting motor position adjustment seat is arranged at the rear of the guide mounting seat, the cutting motor is fixed on the cutting motor position adjustment seat, and the saw blade is arranged at the front end of the saw blade installation shaft The rear end of the saw blade installation shaft and the front end of the cutting motor output shaft are provided with the aforementioned pulley, and the belt connects the cutting motor and the saw blade installation shaft through the pulley. Among them, the output shaft of the cutting motor is of a common structure, and a pin groove is arranged on the side surface of the end portion, and the pulley is installed on it in a matched manner. Since the output shaft of the cutting motor does not have the saw blade directly installed, a saw blade installation shaft and a saw blade bearing need to be additionally installed to install the saw blade. Therefore, a pulley and a belt drive are also required. In order to prevent the belt from loosening due to stretching, it is necessary to pass Adjusting the position of the cutting motor to adjust the distance between the cutting motor and the installation shaft of the saw blade results in complex structure of the cutting assembly, high production cost, easy failure and low reliability. The belt drive is adopted, and the transmission efficiency is low, which is not conducive to energy saving and environmental protection. Moreover, for relatively long profile workpieces, the carrying capacity of the pallet is limited and cannot fully support the profile workpieces.

In addition, when the existing double-head saws process profile workpieces, it is usually necessary to cut the profile workpieces at 45 degrees or 90 degrees. After the bottom edge length is determined, the top edge length needs to be positioned. Due to different profiles The height of the workpiece is different, and the length of the top edge of the profile workpiece is also different when the cutting angle is unchanged. In order to determine the length of the top side (R), after determining the length of the bottom side (L), since the processing angle of the 45-degree angle is an isosceles right triangle, the length of the top side can be obtained by measuring the height (H). The shape of the workpiece after cutting can be divided into two situations:

(1) Both ends are cut at 45 degrees, and the length of the top edge is: R = (2×H) + L;

(2) The two ends are cut into 45 degrees and 90 degrees respectively. At this time, the length of the top edge is: R = H + L.

Under normal circumstances, the height of profile workpieces is measured manually by measuring tools such as vernier calipers, that is, after the relevant data is obtained by manually measuring the height of the material, the length of the top edge is calculated, which leads to the following problems: cumbersome measurement and large error fluctuation; The work efficiency is low, and the reading is not intuitive. When the light is insufficient, it is easy to misread, resulting in processing waste, which is not conducive to energy saving and environmental protection.

When the main seat body 910 swings, the auxiliary positioning shaft 901b can move in the auxiliary arc-shaped hole 901a under the guidance of the auxiliary arc-shaped hole 901a. In this way, the stability of the main seat body 910 when swinging can be greatly improved by means of the cooperation between the auxiliary positioning shaft 901b and the auxiliary arc-shaped hole 901a.

Further, the rotation center line of the metal circular saw blade 21 is arranged perpendicular to the swing axis Y0, and they can be arranged in an intersection (that is, the metal circular saw blade 21 is in the direction of the swing axis Y0). The maximum rotation cutting reference point K0 is also located on the swing axis Y0), or it can be a dislocation arrangement in the up and down direction (for example, the rotation center line of the metal circular saw blade 21 is higher than the swing axis Y0, the The maximum rotation cutting reference point K0 of the metal circular saw blade 21 in the direction of the swing axis Y0 is higher than the swing axis Y0).

Wherein, the rotation center line of the metal circular saw blade 21 is also the rotation center line of the output shaft of the saw blade drive motor 27 (the output shaft on which the metal circular saw blade 21 is installed), and the metal circular saw blade 21 The rotation plane is a rotation plane located on the metal circular saw blade 21 and perpendicular to the rotation centerline of the metal circular saw blade 21 . In theoretical design, the rotation plane of the metal circular saw blade 21 refers to the rotation plane of the meat-biting teeth. The meat-biting teeth refer to the teeth that actually complete the cutting of the profile among all the saw-tooth teeth of the saw blade. Among them, since the rotation center line of the metal circular saw blade 21 is perpendicular to the swing axis Y0, and because the saw slit 9b is parallel to the swing axis Y0 and is defined on the swing axis Y0, it is actually The rotation plane that defines the meat-biting serrations of the metal circular saw blade 21 is always maintained on the rotation axis Y0 in theoretical design, but in actual products, the possible deviation between them is about ±1 mm. acceptable. For this reason, there are many chord lines parallel to the swing axis Y0 on the rotation plane of the metal circular saw blade 21, that is, there can be many cutting points, but only one maximum chord located at the largest diameter Line Y1, the teeth used for cutting profiles at both ends of the maximum chord line is the maximum rotation cutting reference point KO; if the maximum chord line Y1 is also located on the swing axis Y0 (the two overlap each other), that is, The maximum rotational cutting reference point KO is also located on the pivot axis Y0. No matter how the metal circular saw blade 21 is deflected on the angle adjustment seat 91 , there is always a chord for cutting (eg, the largest chord Y1 or other chords) that is always located on the swing axis Y0 . In this way, we can use the swing axis Y0 as a reference to determine the starting point of the profile to be cut so that the length of the profile to be cut can be accurately calculated. According to the above solution, the present invention is designed on the swing axis Y0, so that the design and calculation can be simplified, and the entire machine structure can be simplified. Secondly, after the cut profile is cut, there are left and right ends, and the lowest or highest point on the end face is the position where the meat is initially cut into the meat during rotation in practical applications, that is, the swing axis Y0 is Corresponding to the tooth portion of the lowest point or the highest point of the end face of the cutting profile, the lowest point or the highest point of the end face of the cutting profile is also located on the swing axis Y0. According to the above technical solution, it is not only convenient for the metal circular saw blade 21 to be adjusted at different cutting angles without changing the positions of the cutting table 97 and its saw slit 9b, but also for determining the size of the profile to be cut.

The main seat body 910 can revolve around the swing axis Y0, which does not mean that the main seat body 910 must revolve around the swing axis Y0 within a range of 360°, but has this ability and can only be adjusted according to the cutting angle It can be set according to the needs, for example, it is set to revolve within the range of 45°, 90° or 180°.
