Description

Technical Field

[0001] This utility model relates to the field of processing mold technology, and in particular to an aviation clamp forming mold. Background Technology

[0002] Aviation clamp forming molds are specialized tools used for the precision forming of clamp parts in aircraft piping systems. They are mainly used in the manufacture of fasteners for aero engines, hydraulic systems, and fuel lines. Through high-precision stamping or casting processes, they ensure that the clamps possess characteristics such as vibration resistance and corrosion resistance, meeting the stringent requirements of lightweight and high reliability in aerospace equipment. Existing aviation clamp forming molds generally involve manually placing the steel plate above the stamping mechanism, and then stamping the steel plate through the cooperation of the upper die pressing down and the lower die supporting the steel plate. However, this mechanism lacks a mechanism to limit the movement of the steel plate during use, which can easily cause the steel plate to slip sideways during stamping, resulting in product weight issues. Therefore, the aforementioned problems need to be improved. Utility Model Content

[0021] Example: See Figure 1-6 This utility model discloses an aviation clamp forming mold, comprising a mounting plate 1, with guide rods 2 fixedly connected to all four ends of the top surface of the mounting plate 1, and a stamping table 5 installed in the middle of the top surface of the mounting plate 1. A connecting plate 3 is slidably connected to the guide rods 2. A stamping mechanism is installed on the mounting plate 1, and a limiting mechanism is installed on the stamping table 5. The stamping mechanism and the limiting mechanism facilitate the fixing of the steel plate and improve the stamping accuracy.

The output shaft of the hydraulic cylinders 6 is fixedly connected to the connecting plate 3. A limiting plate 4 is provided above the connecting plate 3, and an upper module 8 is installed in the middle of the bottom surface of the connecting plate 3. The bottom surface of the limiting plate 4 is fixedly connected to multiple guide rods 2. Both sides of the stamping table 5 are convex planes, and the top surface of the stamping table 5... A stamping groove is provided in the middle, which facilitates the installation of the stamping plate and the support block 10. A transverse sliding groove is provided on both sides of the top surface of the stamping table 5. An installation groove communicating with the sliding groove is provided on the opposite side of the sliding groove, which facilitates the electric push cylinder 12 to control the stamping of the extrusion block 13. The limiting mechanism includes extrusion blocks 13 located on both sides of the stamping table 5 and whose lower ends slide in the sliding groove. A support groove is provided at the upper end of the extrusion block 13. A longitudinal sliding groove is provided on the inner bottom surface of the support groove. A bidirectional screw 14 is longitudinally rotatably connected in the support groove. Both ends of the bidirectional screw 14 are threadedly connected to clamps. One end of the bidirectional screw 14 is provided with an internal hexagonal groove. The lower end of the clamp is placed in the sliding groove and slides. The bidirectional screw 14 facilitates the control of the distance between the clamps.

[0022] In this utility model, electric push cylinders 12 are provided on the opposite sides of the extrusion block 13. The electric push cylinders 12 are fixedly connected in the mounting groove, and the output shaft of the electric push cylinder 12 is fixedly connected to the extrusion block 13. The electric push cylinders 12 facilitate the fixing of the steel plate and the stamping of the steel plate. A lower module 7 is installed inside the stamping groove. The lower module 7 consists of two stamping plates. The lower ends of the opposite sides of the two stamping plates are connected to a rotating shaft. The stamping groove is provided with a rotating groove to cooperate with the rotating shaft. A first connecting block is fixedly connected to the upper ends of both ends of the two stamping plates. Two second connecting blocks are fixedly connected to both sides of the stamping table 5. Two connecting blocks are respectively placed at both ends of the stamping table 5. A first spring 9 is connected between the adjacent first connecting block and the second connecting block. The first spring 9 facilitates the control of the stamping plate to reset, which is convenient for subsequent stamping. A movable groove is opened in the middle of the stamping groove. A support block 10 is slidably connected in the movable groove. The upper end of the support block 10 passes through the lower module 7, and the bottom surface of the support block 10 is connected to a second spring 11. The other end of the second spring 11 is connected to the bottom surface of the movable groove. The second spring 11 facilitates the control of the ejection of the support block 10, which is convenient for the clamp to be unloaded after stamping.

[0023] Working Principle: When using this aviation clamp forming mold, firstly, all electrical equipment in the device (including hydraulic cylinder 6, electric push cylinder 12, etc.) must be connected to the power supply to ensure that each power component can operate normally. Then, enter the parameter adjustment stage. Rotate the double-acting screw 14 (operated by the internal hexagonal groove at its end with a tool). Since the lower ends of the clamping plates threaded at both ends of the double-acting screw 14 are placed in the sliding grooves in the support grooves of the extrusion block 13, the two clamping plates can be controlled to move closer or further apart to adapt to the width of the steel plate to be processed. At the same time, by controlling the electric push cylinder 12 installed in the mounting groove of the stamping table 5, the output shaft of the electric push cylinder 12 is extended and retracted, driving the extrusion block 13, which is fixed at one end, to slide in the sliding grooves on both sides of the top surface of the stamping table 5, thereby adjusting the two extrusion blocks. The spacing between blocks 13 is adjusted to match the length of the steel plate to be processed. After the spacing is adjusted, the two ends of the steel plate to be processed are placed in the support grooves on the upper ends of the two extrusion blocks 13. At this time, the steel plate remains stable under the limiting action of the clamping plate. Then, the hydraulic cylinders 6 installed on both sides of the top surface of the mounting plate 1 are activated. The output shaft of the hydraulic cylinder 6 extends and pushes the connecting plate 3 fixed to it to slide down along the guide rod 2. The upper module 8 installed in the middle of the bottom surface of the connecting plate 3 moves down accordingly and stamps the steel plate placed on the stamping table 5. During the process of the steel plate being stamped by the upper module 8, the middle of the steel plate bends downward and enters the stamping groove opened in the middle of the top surface of the stamping table 5, while pressing the lower module 7 (composed of two stamping plates) installed in the stamping groove. The plate rotates around its lower pivot within the slot. At this time, the first connecting blocks above both ends of the stamping plate pull the connected first spring 9 (the other end of the first spring 9 is connected to the second connecting blocks on both sides of the stamping table 5), causing the first spring 9 to be in a stretched state. Simultaneously, the middle of the steel plate presses against the support block 10 in the movable slot in the middle of the stamping groove. The support block 10 slides downwards and compresses the second spring 11 connected to its bottom surface (the other end of the second spring 11 is connected to the bottom surface of the movable slot). When the middle of the steel plate bends to a suitable position, the electric push cylinder 12 is activated. The output shaft of the electric push cylinder 12 pushes the extrusion block 13 to move inwards, using the extrusion block 13 to stamp the upper end of the steel plate, ultimately forming the steel plate into a clamp shape. After the clamp is formed, the output shaft of the electric push cylinder 12 retracts, driving the extrusion block... The pressure block 13 moves outward to reset to its initial position. Then, the output shaft of the hydraulic cylinder 6 retracts, pulling the connecting plate 3 to slide upward along the guide rod 2. The upper module 8 moves upward to reset. At this time, the limiting plate 4 (the bottom surface is fixed to multiple guide rods 2) limits the upward movement of the connecting plate 3. After the upper module 8 resets, the support block 10 slides upward under the elastic restoring force of the second spring 11, popping the formed clamp out of the stamping groove, making it easy for the operator to pick up the material. At the same time, the first spring 9 on both sides, which is in a stretched state, pulls the two stamping plates of the lower module 7, causing the stamping plates to rotate in the opposite direction around the rotating shaft to reset to their initial position, preparing for the next stamping operation. Thus, the stamping forming process of the entire aviation clamp is completed, and the next workpiece processing cycle can begin.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
