Description

Technical Field

[0001] A sawing device for aluminum frame bars with arc cross-section. Background Technology

[0002] Home appliance casings are often made of aluminum profiles. Large home appliances, such as refrigerators and standing air conditioners, have long outer frame lengths, and the connecting ribs need to be machined into irregular shapes. Therefore, there are problems such as long milling tool travel distance, reliance on medium and large equipment for processing, high processing costs, slow processing speed, and high clamping difficulty. Summary of the Invention

[0003] This utility model provides a sawing device for aluminum frame reinforcement with arc cross section, which replaces milling for processing the reinforcement of profiles with sawing. It has the advantages of fast tool movement and high processing efficiency; and it uses a special arc cross section tooling, which is stable and firm, and easy to load and unload.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A sawing device for aluminum frame ribs with arc cross-sections includes a feed rail on the frame, a feed platform slidably connected to the feed rail via a slider, a clamping cylinder mounted on the feed platform, a clamping chuck connected to the piston rod end of the clamping cylinder, and a contour support frame fixedly mounted at the corresponding position of the clamping chuck; a horizontal saw assembly is also mounted on the frame, the saw head of the horizontal saw assembly can move horizontally, and the saw teeth match the position of the connecting ribs of the aluminum workpiece.

[0006] The aluminum profile workpiece with an arc cross section is clamped and fixed between the clamping chuck and the contour support frame. When sawing is required, the feed cylinder pushes the feed platform forward. At this time, the saw blade rotates at high speed and the saw head moves horizontally to cut off the ribs of the fed aluminum profile workpiece.

[0007] The saw head is mounted on a wire block, the bottom of which is slidably connected to a transverse track. A lead screw is inserted through the wire hole of the wire block, and the lead screw is driven by a motor. The other end of the lead screw is rotatably connected to a bearing seat. The motor can be a servo motor or a stepper motor to precisely control the travel distance of the saw head.

[0008] Positioning rods are installed at both ends of the frame, and movable positioning blades are mounted on the support plates at preset positions on the positioning rods. The positioning blades are used to position the ends of the aluminum profiles, and the support plates are used to support the weight of the aluminum profiles.

[0009] Advantages of utility models

[0010] 1. This utility model is specifically used for processing the ribs of aluminum profiles for appliance frames with arc cross-sections. It replaces milling with sawing for processing the ribs of the profiles, which has the advantages of fast tool movement and high processing efficiency; it can avoid the use of large milling equipment and reduce equipment procurement costs.

[0011] 2. This utility model uses a special arc-shaped cross-section tooling, which clamps the workpiece stably and firmly, and is easy to load and unload.

[0012] 3. This utility model can be used for positioning workpieces of multiple lengths, has good adjustability, and has a wide range of applications. Attached Figure Description
