Description

Technical field:

[0001] The utility model relates to the technical field of profile sawing processing, in particular to a sawing machine head for avoiding scratching of finished materials. Background technology:

[0002] Doors and windows are made from profiles through multiple processes such as sawing, milling, and angle setting, among which sawing is an indispensable process. Double-head saws are profile cutting tools used in the production of doors and windows. Due to their high efficiency, low cost, wide range of applications, and high precision, they have been widely promoted and applied. At present, the working principle and main structural layout of double-head saws are relatively mature. They include a bed, a left saw head is provided at one end of the bed, a guide rail is provided on the bed, and a right saw head is provided on the guide rail. The left and right saw heads cooperate to cut the profiles. The main structure of the left and right saw heads is the same, and they mainly use a linear feed method for cutting. In order to meet the needs of sawing at different angles, they can also be designed into a swing angle structure to achieve cutting at different angles. For the specific structure, please refer to a double-head saw structure with arbitrary swing angle disclosed in a Chinese patent (authorization announcement number: CN105478891B). The promotion and application of double-head saws has greatly promoted the development of the door and window industry.

[0003] In recent years, with the rapid development of the door, window, and home improvement industries, users have placed higher demands on the processing quality of door and window profiles, and correspondingly, on sawing quality and precision. In actual applications, users have reported scratches on the sawn surfaces at both ends of finished profiles. The most direct impact of these scratches is that the two mating surfaces do not align tightly during corner assembly, creating gaps and resulting in insufficient sealing of the doors and windows. While these scratches may be acceptable for less demanding applications, they are unsatisfactory for demanding applications, such as those in the home improvement industry. Our company has conducted in-depth analysis of the sawing scratch issue and identified two main causes. First, the saw blade's state during forward cutting differs from its state during retraction. During forward cutting, the saw experiences significant resistance, while during retraction, there is little or no resistance. This altered cutting state causes contact with the sawed surface during retraction, resulting in scratches. Second, variations in the assembly precision of the double-head saw itself and the machining accuracy of its components can be present, which can be reflected in the sawing process, causing scratches on the retraction blade. In response to the above-mentioned problems, the prior art has provided a solution, namely, by moving the waste material or finished material after sawing to create a gap between the saw blade and the sawing surface, thereby ensuring that the saw blade does not contact the sawing surface when retreating. For example, a Chinese patent discloses a sawing machine that can return materials and return the blade (authorization announcement number: CN201728430U). The above solution is indeed effective in preventing the saw blade from scratching the profile when retreating to a certain extent, but it is found that there are still limitations in practical applications. The above solution is mainly suitable for fixed-angle sawing, and for swing-angle sawing, the movement of waste material or finished material is restricted due to the influence of the inclination angle of the saw blade, and thus it is impossible to achieve movement to create a safe gap. Therefore, it is necessary to design a new solution to prevent damage to finished materials, in order to meet the needs of swing-angle sawing while effectively avoiding scratching the finished materials.

[0004] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility model content:

[0005] The purpose of the utility model is to solve the problems existing in the prior art and provide a sawing head for cutting finished materials without scratching them. The utility model has the advantages of reasonable structural design, wide application range, good scratch-free effect, etc.

This allows the saw blade to move a short distance away from the finished material before retracting after cutting the profile, creating a safe retraction gap. The saw blade then retracts, ensuring the finished material is not damaged. This damage-free structure is not restricted in direction and can meet the requirements of cutting at different cutting angles. Description of the drawings:
