A three-head saw for processing aluminum alloy door frames

Abstract

The invention relates to the technical field of three-head saws, in particular to a three-head saw for processing aluminum alloy door frames, including slide rails, No. No. 1 cylinder, No. 1 inclined knife and No. 1 protective shell are installed on the No. 2 workbench; No. 2 air cylinder, No. 2 inclined knife, flat knife and No. 2 protective shell are installed on the No. 2 workbench; the aluminum alloy door frame is processed The three-head saw also includes a feeding module and a controller; the feeding module is arranged close to the feeding plate, and the feeding module includes a supporting plate, a rolling rod and a roller; the supporting plate is at least two, and the supporting plate is located on the feeding plate above; the present invention drives the outer frame to slide along the feeding plate through the feeding module, and then cooperates with the No. 1 inclined knife, the No. Manual feeding causes safety hazards to workers, and the present invention also has the characteristics of economy, practicality, convenient operation, high precision and high efficiency.

Description

technical field [0001] The invention relates to the technical field of three-head saws, in particular to a three-head saw for processing aluminum alloy door frames. Background technique [0002] In the current door, window and curtain wall industry, the traditional double-head saw has a narrow range of cutting angles for profiles. If the vertical direction is taken as the benchmark, the traditional double-head saw can only swing from the vertical direction to the inside to 22.5 degrees, or Swing outward from the vertical direction to a range of 22.5 degrees, but cannot swing inwardly and outwardly at the same time. In the actual production process, cutting from two directions at the same time cannot be satisfied; therefore, a three-head saw is introduced in the market now. Compared with the double-headed saw on the market, the three-headed saw needs to change the angle three times to cut a side-hung door, which cannot guarantee the angle accuracy, and also needs to be cut wi...

Problems solved by technology

[0002] In the current door, window and curtain wall industry, the traditional double-head saw has a narrow range of cutting angles for profiles. If the vertical direction is taken as the benchmark, the traditional double-head saw can only swing from the vertical direction to the inside to 22.5 degrees, or Swing outward from the vertical direction to a range of 22.5 degrees, but cannot swing inwardly and outwardly at the same time. In the actual production process, cutting from two directions at the same time cannot be satisfied; therefore, a three-head saw is introduced in the market now. Compared with the double-headed saw on the market, the three-headed saw needs to change the angle three times to cut a side-hung door, which cannot guarantee the angle accuracy, and also needs to be cut with a grinding block. The grinding block for each profile is not universal, resulting in The replacement is cumbersome, and the three-head saw solves the problem of cutting the outer frame of all door factories; however, due to the lack of existing technology, after the outer frame is cut, workers need to wait until the protective shell is opened, then manually push the material, and then cut. The process is cumbersome and time-consuming, and it also poses safety hazards to the workers' health

[0003] In the prior art, there are also some technical solutions about the three-head saw for aluminum alloy door frame processing. For example, a Chinese patent with the application number CN201120074683. The head saw table includes: a machine table, which includes a control panel in front, an auxiliary frame and a fixed saw table on one side of the machine table, which are arranged at the upper middle section of the machine table, and the back side of the fixed saw table extends the first extension plate, the first extension plate is equipped with a first air pump seat, the first air pump seat is fixed inside the first air pump, the main shaft of the first air pump is connected to the first motor, and the main shaft of the first motor is connected to the second A circular saw blade, a first protective cover is fixed on the periphery of the first circular saw blade, and the inner and outer sides of the protective cover are provided with a first movable block, and a first slot hole corresponding to the circular saw blade is reserved on the fixed saw table , a fourth air pump is respectively arranged on the upper side and the side of the fixed saw table, and the ends of the fourth air pump are respectively connected to the first pressure levers; High-degree saw heads, and each end is equipped with a set of saw heads that can adjust the left and right positions, cutting slope and section angle. With the three saw heads descending at the same time, it can cut two sections of preset end edge slopes at a time. Aluminum frame strips with cross-sectional angles; however, this technical solution requires workers to wait until the protective shell is opened before manually pushing the material after the outer frame is cut.
