Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy profile processing technology, specifically to a processing equipment for extra-long aluminum frames of refrigerators. Background Technology

[0002] The frames of refrigerators are often made of aluminum profiles, which have advantages such as being lightweight, corrosion-resistant, and having a high surface finish. When processing aluminum profiles for refrigerator frames, it is necessary to mill long grooves and other shapes along the edges of the profiles. However, due to their considerable length, sometimes reaching 2 meters, using ordinary machining centers or CNC milling machines would result in several problems. First, the processing volume would be large, the milling cutter travel time would be long, and the processing cost per workpiece would be high. Second, because of the long cutter travel, the required milling equipment would be correspondingly large, leading to high equipment costs and operating costs, further increasing the processing cost of the workpiece. Summary of the Invention

[0003] The purpose of this invention is to provide a processing equipment for extra-long aluminum frames of refrigerators, which is specifically designed for processing long grooves on the edges of extra-long aluminum profiles. It uses a circular saw instead of a traditional milling cutter, resulting in high processing efficiency, low equipment cost, and a significant reduction in the processing cost of extra-long aluminum frames for refrigerators.

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

[0005] A refrigerator extra-long aluminum frame processing equipment has several saw head slide rails installed along the length of the upper end face of the frame. The saw head is slidably connected to the slide rail via a slider. The saw head is fixedly connected to a walking motor. The rotating shaft of the walking motor is connected to the frame via a gear and rack.

[0006] The traveling circular saw head saws the edges of the workpiece by rotating at high speed, which is more efficient than milling with a milling cutter and the equipment is smaller in size; the rack is mounted on the frame and the traveling motor drives the saw head to move laterally while the workpiece is stationary and being cut.

[0007] The upper end face of the frame is provided with several movable seat slide rails and movable seat cylinders in the width direction. The movable seat slide rails are slidably connected to the movable seats through sliders. The movable seats are driven to slide by the movable seat cylinders. Several pressing cylinders are provided on the movable seats. Pressing blocks are installed at the piston rod ends of the pressing cylinders. The pressing blocks match the shape of the aluminum profile. Support plates are also installed on the movable seats. The aluminum profile is supported by the support plates. The edge of the aluminum profile to be processed extends out from the gap of the support plate and contacts the saw blade of the saw head.

[0008] The movable seat is driven by a cylinder to move back and forth, thereby moving the workpiece back and forth. When the movable seat cylinder moves forward, the workpiece contacts the saw teeth of the saw blade to achieve sawing. When the movable seat cylinder retracts, the workpiece separates from the saw blade and no processing is performed. When the movable seat moves forward and retracts intermittently, intermittent processing grooves can be processed on the edge of the workpiece to form an intermittent groove on the edge of the workpiece.

[0009] The clamping block and support plate stably hold the aluminum profile, ensuring that the aluminum profile remains stable and does not slip during movement and sawing.

[0010] Spring limiters are installed at both ends of the saw head slide rail. The spring limiters prevent the saw head from moving beyond its limit.

[0011] Limit switches are installed at both ends of the saw head slide rail. When the limit switch is contacted by the saw head, it sends a signal to the PLC, which then controls the travel motor to stop running, the saw head to stop rotating, and the sawing process ends, allowing the operator to change the workpiece.

[0012] One end of the frame is equipped with a chip collection and suction pipe. The other end of the suction pipe is connected to a suction fan and a chip collection trough to collect and process sawdust.

[0013] Advantages of utility models

[0014] 1. This utility model is specifically designed for processing long grooves on the edges of extra-long aluminum profiles.
