Description

Technical Field

[0001] The utility model relates to the technical field of thermal break aluminum cutting, in particular to a square box intelligent saw for cutting thermal break aluminum profiles. Background Art

[0002] Thermally insulated aluminum, also known as thermally insulated aluminum profiles, thermally insulated aluminum alloy profiles, thermally insulated aluminum alloys, thermally insulated cold and hot bridge profiles, and thermally insulated aluminum-plastic composite profiles, is a new type of thermally insulated aluminum profile. It offers a range of advantages, including high strength, excellent thermal insulation, rigidity, fire resistance, a large lighting area, excellent atmospheric corrosion resistance, high overall performance, long service life, and excellent decorative effects. Profiles often require simultaneous cutting at both ends, such as door and window profiles, which require cutting at right angles or 45-degree angles. To increase the processing speed of these profiles, a double-head saw is often used.

[0003] There is an existing application number 201910891418.9, which is a double-head saw cutting machine, which includes a horizontal gantry frame; a linear rail is arranged on the top of the horizontal gantry frame; a sliding seat is slidably arranged on the linear rail, and a fixed seat is fixed on the left end of the horizontal gantry frame; a transmission frame is connected to the outside of the horizontal gantry frame, and a transmission rack is provided in the transmission frame; two groups of saw blade cutting units are arranged on the horizontal gantry frame opposite to each other on the left and right; a material height measuring device and a material support frame are arranged on the right side of the sliding seat; a movable material rack is slidably arranged on the right side of the linear rail and opposite to the material support frame on the left and right; a driving device is arranged on the outside of the sliding seat, and drives the sliding seat to slide left and right on the linear rail through the transmission rack.

[0004] The machine head in the above scheme is usually composed of a bottom plate, a front plate, a rear plate and a swing angle mechanism where the saw blade is located. Currently, there are the following defects:

[0005] 1. The front and rear vertical plates are machined with axial holes for the swing mechanism to rotate. During assembly, the front and rear vertical plates are bolted to the front and rear ends of the base plate. The axial holes must be completely concentric to ensure flexible swinging of the swing mechanism and accurate cutting angles. Because the diameter of the axial hole in the front and rear vertical plates differs, workers are required to use a specially designed stepped fixture shaft during installation. They also use a gauge to align the upper and lower busbars of the fixture shaft, repeatedly adjusting the position of the front and rear vertical plates before finally locking them in place with nuts and driving locating pins. This complex assembly process requires a high level of skill and is challenging to maintain and adjust later.

[0006] 2. To ensure the flexible rotation of the angular mechanism, the current design incorporates self-lubricating copper bushings on the front and rear vertical plates to reduce radial friction. Spacers are installed between the front vertical plate and the front end of the angular mechanism, and between the rear end of the angular mechanism and the rear vertical plate to eliminate axial play in the machine head and prevent the angular mechanism from moving back and forth. Over time, the self-lubricating copper bushings and spacers wear out, causing radial and axial play that affects cutting accuracy. Utility Model Content

[0007] The purpose of the utility model is to solve the above problems and provide a square box intelligent saw for cutting broken bridge aluminum profiles, which has a simplified structure, high assembly efficiency, good casting stability, small swing angle friction resistance, convenient later maintenance, and improved machine tool accuracy.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A square box intelligent saw for cutting thermally broken aluminum profiles comprises a base and a machine head arranged in parallel on the base, the machine head on the right side moves on the base, and a first supporting mechanism for supporting the end of the thermally broken aluminum profile is provided at the right end of the base, the machine head comprises a base supported on the base, a rotating frame arranged on the base and rotating on the base, a motor is provided on the rotating frame, a cutting saw blade is provided on the motor output shaft, the front vertical plate, rear vertical plate and bottom plate of the base are cast as one piece, a bearing seat is provided on the front vertical plate of the base, and two horizontal long strip mounting holes are symmetrically provided on the bearing seat.

[0010] Furthermore, a positioning block is provided at the left end of the base for positioning the left end of the thermal break aluminum and moving on the base, and a plurality of second supporting mechanisms for supporting the end of the thermal break aluminum are provided on the base.

[0011] Furthermore, a first guide rod is provided on the outer side of the positioning block, and a guide sleeve that cooperates with the first guide rod is provided on the base.

[0012] Furthermore, a first cylinder for driving the positioning block to move is provided on the base, a cylinder body end of the first cylinder is fixed on the base, and a piston rod end of the first cylinder is connected to the positioning block.

[0013] Furthermore, the second supporting mechanism includes a lifting plate that is arranged on the base and rises and falls on the base.

[0014] Furthermore, a second guide rod is provided at the bottom of the lifting plate, which passes through the base and is slidably connected to the base. The bottom of the base is provided with a lifting cylinder, the cylinder body end of the lifting cylinder is fixed on the base, and the piston rod end of the lifting cylinder is connected to the lifting plate.

[0015] Furthermore, a second cylinder for driving the rotating frame to rotate is provided on the base, a cylinder body end of the second cylinder is connected to the base, and a piston rod end of the second cylinder is connected to the bottom of the rotating frame.

[0016] Furthermore, the first supporting mechanism includes a lifting wheel which is arranged at the right end of the base and is lifted and lowered at the right end of the base.

[0017] Furthermore, a thrust ball bearing is provided on the outer side of the bearing seat for radially pulling the rotating shaft at the front end of the rotating frame.

[0018] The beneficial effects of the utility model are:

[0019] 1. The front, rear, and bottom plates of the base are cast as a single unit, with additional reinforcement beams, forming a cast square box. This box is machined to ensure precise positioning of the mounting holes. Artificial aging treatment ensures structural stability and resists deformation, enhancing the stability of the equipment.

[0020] 2. The utility model is provided with a bearing seat on the front vertical plate of the base, and a thrust ball bearing is provided between the bearing seat and the front rotating shaft of the rotating frame to reduce wear, prevent radial and axial clearances, and ensure cutting accuracy. Two horizontal long strip mounting holes are symmetrically provided on the bearing seat, and the front mounting shaft hole is an independent bearing seat. The two mounting holes of the bearing are long horizontal holes, which are convenient for fine-tuning the horizontal position of the bearing seat. The vertical direction is adjusted by adding a pad. During installation, instead of adjusting the front and rear vertical plates, only the front bearing seat needs to be adjusted, which greatly reduces the difficulty of adjustment. Moreover, as the use time is extended, even if fine-tuning is needed later, there is no need to move other parts, only the bearing seat needs to be fine-tuned. Later maintenance and repair are convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] like Figure 1 and Figure 2 As shown, a square box intelligent saw for cutting thermally broken aluminum profiles includes a base 1 and a machine head arranged in parallel on the base 1. The right machine head moves on the base 1. The right end of the base 1 is provided with a first supporting mechanism for supporting the end of the thermally broken aluminum. The machine head includes a base 8 supported on the base 1, a rotating frame 9 arranged on the base 8 and rotating on the base 8, a motor is provided on the rotating frame 9, a cutting saw blade 10 is provided on the motor output shaft, and a motor is provided on the rotating frame 9, a cutting saw blade 10 is provided on the motor output shaft. The base of the right machine head is slidably connected to the base 1 through a guide rail slider pair, and the base and the base 1 are driven by a gear rack. This is the existing technology and will not be elaborated on here. A fixing mechanism for fixing the thermally broken aluminum is symmetrically provided on the base. The fixing mechanism includes vertical pressing and lateral pressing, including a cylinder and a pressure head provided at the end of the cylinder piston rod, thereby achieving the fixation of the thermally broken aluminum.

[0028] like Figure 1 and Figure 2As shown, the front, rear, and bottom plates of the base 8 are integrally cast, with additional reinforcement beams added to form a cast square box. The cast box is machined to ensure the precise positioning of the mounting holes. After artificial aging, the cast box maintains a stable structure and resists deformation, enhancing the stability of the equipment. This integral casting eliminates numerous screw connections, pin holes, and adjustment steps, making installation and adjustment more convenient, reducing the skill requirements for assemblers, and improving assembly efficiency. The rear end of the turret 9 is pivotally connected to the base 8. The rear mounting axis hole is a separate axle seat, referred to as the rear axle seat, which fits tightly within the cast, matching axis hole and is non-adjustable. A bearing seat 13 is provided on the front plate of the base 8. A thrust ball bearing is positioned between the bearing seat and the front shaft of the turret 9 to reduce wear, eliminate radial and axial play, and ensure cutting accuracy. Two horizontal, elongated mounting holes 14 are symmetrically arranged on the bearing seat 13. The front mounting axis hole is a separate bearing seat, and the two bearing mounting holes are horizontal, elongated holes, facilitating fine-tuning of the horizontal position of the bearing seat. Vertical adjustment can be achieved by adding a shim. During installation, adjustments only need to be made to the front bearing seat, significantly simplifying adjustments. Furthermore, even if fine-tuning is required over extended periods of use, no other components need to be moved, only the bearing seat. This facilitates subsequent maintenance. A thrust ball bearing 15 is located on the outer side of the bearing seat 13, radially pulling the front shaft of the turret 9.

[0029] like Figure 1 As shown, the left end of the base 1 is provided with a positioning block 2 for positioning the left end of the thermally-insulated aluminum and moving on the base 1. The base 1 is provided with a plurality of second support mechanisms for supporting the ends of the thermally-insulated aluminum. When performing a 45-degree cut on the thermally-insulated aluminum, the position of the positioning block 2 is first adjusted according to the thickness of the thermally-insulated aluminum. The end of the thermally-insulated aluminum is positioned by the positioning block 2. There is no need to manually check back and forth whether the cutting position of the left end is appropriate. The operation is simple and convenient, and at the same time, it can minimize the waste caused by cutting and reduce waste. If the length of the thermally-insulated aluminum after cutting is too long, the second support mechanism is used to support the middle position of the thermally-insulated aluminum, so that the thermally-insulated aluminum will not bend, ensuring the accurate length of the thermally-insulated aluminum after cutting.

[0030] like Figure 1 and Figure 2 As shown, a first guide rod 3 is provided on the outer side of the positioning block 2 , and a guide sleeve 4 that cooperates with the first guide rod 3 is provided on the base 1 .

[0031] The base 1 is provided with a first cylinder 5 for driving the positioning block 2. The cylinder end of the first cylinder 5 is fixed to the base 1, and the piston rod end of the first cylinder 5 is connected to the positioning block 2. Because different thicknesses of thermally-insulated aluminum require different distances to be reserved on the thermally-insulated aluminum when cutting at a 45-degree angle, the first cylinder 5 is used to drive the positioning block 2 to move left and right, thereby preventing excessive waste caused by excessively long reserved distances and preventing incomplete bevels from being cut due to insufficient reserved length.

[0032] like Figure 1 and Figure 2 As shown, the second supporting mechanism includes a lifting plate 6 that is arranged on the base 1 and is lifted and lowered on the base 1 .

[0033] like Figure 3 As shown, a second guide rod 7 is provided at the bottom of the lifting plate 6, which passes through the base 1 and is slidably connected to the base 1. The bottom of the base 1 is provided with a lifting cylinder, the cylinder body end of the lifting cylinder is fixed on the base 1, and the piston rod end of the lifting cylinder is connected to the lifting plate 6.

[0034] A second cylinder 11 for driving the rotating frame 9 to rotate is provided on the base 8 , the cylinder end of the second cylinder 11 is connected to the base 8 , and the piston rod end of the second cylinder 11 is connected to the bottom of the rotating frame 9 .

[0035] like Figure 1 As shown, the first supporting mechanism includes a lifting wheel 12 arranged at the right end of the base 1 and lifted and lowered at the right end of the base 1. The right end of the thermally broken aluminum is supported by the lifting wheel 12. A lifting cylinder is provided at the right end of the base 1. The cylinder end of the lifting cylinder is fixed on the base. The piston rod end of the lifting cylinder is connected to the bracket of the lifting wheel 12. The lower end of the bracket of the lifting wheel 12 is provided with a guide rod that passes through the base and is slidably connected to the base.
