An automatic short-side cutting device for aluminum profiles

Abstract

This invention relates to the field of aluminum material cutting, specifically to an automatic short-side cutting device for aluminum profiles. The device includes a base assembly with an adjustment section at its top. The adjustment section includes a top support frame with a front mounting groove on its top front side. A torsion block is movably connected inside the front mounting groove. The base assembly has two sets of top components at its top, each with an auxiliary top component fixedly connected to its top. Each auxiliary top component includes a displacement block, with a connecting rod fixedly connected to its top. The connecting rod is rotatably connected to a flipping block. The torsion block is connected to the cutting section via a synchronous insertion rod. When switching between vertical and oblique cutting states, the synchronous insertion rod drives the torsion block to rotate synchronously, ensuring that the retraction groove in the middle of the torsion block always precisely aligns with the cutting edge of the cutting disc, allowing the cutting edge to smoothly enter the retraction groove. In the intelligent manufacturing equipment industry, this prevents scratching the profile surface during cutting operations and provides protection for the saw blade while maintaining cutting stability.

Description

Technical Field

[0001] This invention relates to the field of aluminum material cutting, specifically to an automatic short-side cutting device for aluminum profiles. Background Technology

[0002] With the booming development of the intelligent manufacturing equipment industry, various industries are increasingly demanding higher production efficiency, processing precision, and automation levels. Aluminum profiles, with their excellent properties such as light weight, high strength, and corrosion resistance, have been widely used in many fields such as construction, transportation, and electronics. As the application scenarios of aluminum profiles continue to expand, the requirements for their processing precision and efficiency are becoming increasingly stringent. Cutting is a crucial step in the aluminum profile processing flow, especially short-side cutting, as its processing quality directly affects the assembly precision and overall performance of subsequent products. Traditional methods of short-side cutting of aluminum profiles mostly rely on manual operation. Operators need to hold cutting tools and rely on their own experience and skills to cut the aluminum profiles. Therefore, a cutting device is needed to facilitate the cutting of aluminum profiles.

[0003] In the intelligent manufacturing equipment industry, aluminum profiles are typically cut using a saw in aluminum profile processing scenarios. However, in the cutting and positioning stage, the aluminum profile is mainly fixed by manual hand-holding and clamping. The operator's limbs need to be close to the high-speed rotating saw blade. When the aluminum profile accidentally slips or the operator makes a mistake during the cutting process, it is very easy to cause cutting injury accidents. At the same time, the existing sawing equipment has limitations in its tool groove structure design. It is mostly a fixed shape and cannot be dynamically adjusted according to the actual working conditions such as saw blade specifications and cutting angle. When performing oblique cutting operations, because the saw blade is in an inclined state with the fixed tool groove, the actual retraction space is compressed. This causes the saw blade to frequently make hard contact with the inner wall of the tool groove during the return stroke. This not only accelerates saw blade wear but may also cause saw blade breakage, equipment failure and other serious consequences, affecting production continuity and processing accuracy. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The two sets of top-mounted displacement blocks are slidably connected to the outer frame. Through the cooperation of the positioning holes and the top cylindrical rod of the clamping plate, the top part can be quickly positioned and fixed on the bottom part, ensuring that the aluminum profile can be firmly clamped during the cutting process. The shrinkage support plate slides in the displacement groove and can be adaptively adjusted according to the size of the aluminum profile, enhancing the stability of clamping. The displacement block of the auxiliary top can slide on the top of the displacement block, and the position can be precisely adjusted through the displacement screw. After the aluminum profile is initially clamped, the flipping block is flipped by the toggle rod, which simultaneously drives the flipping clamping block to contact the aluminum profile, so that the flipping clamping block clamps the part close to the cutting position. Under the action of the flipping clamping block and the auxiliary clamping block, the aluminum profile is fully clamped. At the same time, it is convenient for the operator to quickly adjust the clamping position and angle, achieve precise clamping and positioning of the aluminum profile, improve the convenience and efficiency of operation, and avoid the operator's limbs being close to the saw blade during the cutting operation in the intelligent manufacturing equipment industry, thus preventing cutting injury accidents during the cutting process.

[0016] 2. The top support frame in the adjustment section can rotate around the top of the bottom mounting plate, and the rotation angle can be precisely quantified through the measuring plate. At the same time, the tilting frame of the flipping section can be adjusted in angle through the docking screw hole under the drive of the locking rod, thereby driving the flipping guard and cutting disc of the cutting section to change the angle. This multi-dimensional angle adjustment method can meet the short side cutting needs of aluminum profiles with various complex angles. The torsion block is connected to the cutting section through the synchronous insertion rod. When switching between vertical cutting and oblique cutting, the synchronous insertion rod drives the torsion block to rotate synchronously, ensuring that the retraction groove in the middle of the torsion block always accurately corresponds to the blade of the cutting disc. After cutting, the blade can smoothly enter the retraction groove, avoiding scratching the surface of the profile and ensuring cutting quality and accuracy. At the same time, it protects the saw blade while maintaining cutting stability. Attached Figure Description

[0041] In this embodiment, the displacement block 601 is slidably connected to the top of the displacement base block 501. By rotating the displacement screw 603, the displacement block 601 can slide within the displacement groove 504, thereby adjusting the position of the auxiliary clamping block 602 and initially clamping the aluminum profile. Subsequently, by moving the actuating rod 607 on the flipping block 605, the flipping block 605 can be rotated around the connecting rod 604, causing the flipping clamping block 606 to adjust its angle and further clamp the aluminum profile from different directions, ensuring that the aluminum profile will not shift during the cutting process. In addition, the top baffle 505... The shrinkage support plate 507 can slide within the displacement groove 506, and can adaptively adjust according to the cross-sectional shape and size of the aluminum profile, providing more stable support for the aluminum profile. Under the action of the flipping clamping block 606 and the auxiliary clamping block 602, the aluminum profile is fully clamped. At the same time, it is convenient for operators to quickly adjust the clamping position and angle, so as to achieve precise clamping and positioning of the aluminum profile, improve the convenience and efficiency of operation, and avoid the operator's limbs from being close to the saw blade during the cutting operation in the intelligent manufacturing equipment industry, thus preventing cutting injury accidents during the cutting process.
