[0002] Aviation sheet metal parts account for a large proportion in aircraft manufacturing, and their processing accuracy and efficiency directly affect the safety and performance of the aircraft.

[0003] Corner parts are an important part of aircraft structure. They are produced in huge quantities and require high precision. Traditional manual or semi-automatic feeding methods can no longer meet the needs of modern aviation manufacturing.

[0004] Therefore, it is particularly important to develop an automatic feeding system that can improve processing efficiency, ensure processing accuracy, and adapt to complex part shapes. Summary of the invention

[0005] The present invention aims to provide a modular bending parts feeding mechanism suitable for aviation sheet metal parts, especially corner pieces, to solve the problems of low processing efficiency, unstable precision, complex operation, etc. existing in the prior art. The device has the following characteristics: (1) High precision: ensure the positioning accuracy of parts during the bending process to meet the standard requirements of the aviation manufacturing industry. (2) High efficiency: improve the automation level of bending processing, reduce manual operations, and shorten the production cycle. (3) Versatility: can adapt to corner pieces of different shapes and sizes, and has good adaptability and expansibility. (4) Easy to operate: simplify the operation process, reduce the difficulty of operation, and improve production efficiency.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A modular bending part feeding device is a new type of modular bending part feeding device, which is used for processing metal sheet bending parts. The modular bending part feeding device comprises a base 2, a guide mechanism 1 located on the base 2, a feeding mechanism, a pressing mechanism 5 and a blanking mechanism 7, and each part is made of high-strength and lightweight materials. The details are as follows:

[0008] The base 2 is made of lightweight materials with guaranteed strength, and the whole is milled and processed by 7050-T7451 grade aluminum alloy thick plate material. The base 2 serves as the main structure of the entire device, so that the mechanical operation of each component is linked together through the base 2. The base 2 includes the ball between the push rod 4 and the base in the feeding mechanism, and the limit slider part of the guide plates on both sides of the guide mechanism. The left and right first step surfaces adjacent to the middle plane are used to install the guide mechanism 1, and the first step surface is provided with a limit slider for limiting the displacement of the guide mechanism. The plane between the base 2 and the guide plates on both sides is symmetrically provided with two rows of cylindrical rollers along the length direction, and the ball is used to assist the guide plates 2 on both sides to move on the base 1. Knob bolts are respectively provided at the left and right ends of the base 2, and the root of the knob bolt is connected to the guide plate to adjust the position of the guide plate on the base 2 from both sides, which is used for the lateral movement of the guide plates on both sides.

[0009] The guide mechanism is composed of two precisely machined and assembled guide plates, which are located above the base 2. The guide plates are symmetrical in length, and the two sides to the middle are stepped structures, which match the size of the two rows of cylindrical rollers of the base 2. Two rows of scales are provided on the upper surfaces of the two guide plates, and a precise guide groove is formed between the scales and the upper surfaces of the guide plates. The rough material of the parts to be processed is placed on the upper surfaces of the guide plates, and the positions of the two sides of the parts are limited by the scales on both sides. The height of the formed guide groove, that is, the height of the upper surface of the guide plate and the bending knife groove of the bending equipment, is kept horizontal so that the parts can be sent to the top of the knife groove. Ensure the stability and accuracy of the parts during the feeding process. The guide plate and the base move laterally through bolts and cylindrical rollers, and the lateral movement serves to adjust the width of the guide groove.

[0010] The feeding mechanism is located in the middle of the base 2, and includes a push rod 4 and a movable ejector block 3. The push rod 4 and the base 2 slide through a ball bearing. The movable ejector block 3 is located at the end of the push rod 4 and is detachable from the push rod 4. The size and shape of the movable ejector block 3 can be customized according to the specific needs of the parts, enriching the richness of the machinable parts. When the entire mechanism is working, the rough material of the part to be processed is placed in the guide groove, and the position of the part on the left and right sides is limited by the stopper of the guide plate. The push rod 4 is used to control the stroke of the movable ejector block from the rear. The push rod 4 can be pushed and pulled back and forth from the rear to make the movable ejector block reciprocate back and forth. The movable ejector block 3 is used to eject the rough material of the part located in the guide groove. Push the push rod 4 forward, and the front end of the movable ejector block 3 supports the rough material of the part, and the part is sent to the bending knife groove of the bending equipment.

[0011] The pressing mechanism 5 is designed with a slider, connecting rod and rollers. The reasonable layout of the rollers can effectively prevent the parts from derailing during the feeding process. The pressing mechanism 5 is located at the front end of the base 2 close to the knife groove of the bending equipment. The fixed plates on both sides of the blanking mechanism 5 are connected to the two sides of the base 2. The roller shaft is limited by the fixed plate. By setting a spring on the fixed plate, a downward force is applied to the roller to drive the roller to press the parts. The design of the pressing mechanism 5 takes into account the light weight of the aviation sheet metal itself, and can prevent the parts from slipping out of the guide groove during the forward feeding of the parts, thereby improving the stability of the feeding.

[0012] The blanking mechanism 7 is used to drop the stacked parts into the guide groove one by one through the reciprocating motion of the feeding mechanism. The blanking mechanism 7 includes a support plate and limit pillars 6 in four directions. The support plate is located above the base 2. The four corners of the support plate are fixedly connected to the base 2 by bolts. The middle of the support plate is hollowed out for placing the stacked parts. The grooves in the four directions of the support plate are used to place the limit pillars 6 and limit the displacement direction of the limit pillars 6. The limit pillars 6 can adjust their positions on the support plate, and the limit pillars 6 as a whole play a role in fixing the position of the stacked parts. At the same time, the limit pillars at the front end of the guiding direction also play a role in limiting the feeding of only one piece each time. The specific method is to place a gasket in the groove at the front end of the guide direction of the support plate, and then place the limit pillar in the groove. By using gaskets of different specifications and thicknesses, the height below the limit pillar is adjusted, thereby adjusting the thickness of the part plate allowed to pass through, and this method increases versatility.

[0013] The base 2, feeding mechanism, guide mechanism 1, pressing mechanism 5 and blanking mechanism 7 are all modularly designed. Each base 2 and the mechanism form an independent bending part feeding device, that is, the device can feed once after one push-pull reciprocating motion. The base 2 is the main body for connecting various mechanisms. Its modular design allows the bases to be installed in a row and various devices to be connected side by side. Figure 1 The figure shows a feeding device in which three devices are connected in parallel as a whole. Each of the devices has a set of the above-mentioned mechanisms. The feeding mechanism can coordinate the movement of all feeding mechanisms at the same time by adding a connecting rod at the rear end, that is, three parts can be fed out at the same time by one push-pull reciprocating movement. In addition, the fixing bolt positions are arranged below the two sides of the base 2 of each device, which is used for disassembly and installation between the bases. That is, they are connected through the base 1, and the push rod 4 is connected through the connecting rod. When multiple units are connected side by side, they are in a parallel form.

[0014] In actual use, the number of units can be freely combined according to the quantity and efficiency requirements. It only requires expanding the working platform area and adding the corresponding number of unit modules.

[0015] A method for using a modular bending part row feeding device, comprising the following contents:

[0016] First, place the bending feeding device in the working area of ​​the bending equipment, on the workbench that comes with the equipment or on an additional independent workbench, so that the overall height of the device meets the height of the lower surface of the guide plate and fits the upper surface of the knife groove, so that the parts can be fed above the knife groove.

[0017] Secondly, after the overall position is fixed, the parts to be processed are stacked and aligned according to the shape, and placed in the blanking device of the mechanism. The width of the guide plate is manually adjusted by the knob, and the lower parts of the stack are limited by the stoppers on both sides of the guide plate. The upper parts of the stack are fixed in position by the limit pillar 6 of the blanking mechanism, and the blanking limit pillar is adjusted to a suitable position. According to the thickness of the processed parts, a gasket of appropriate thickness is selected, and the gasket is placed in the groove at the front end of the guide direction of the blanking mechanism, and then the limit pillar at this position is placed on the groove, limiting that only one piece will be ejected each time the material is fed.

[0018] Then, by pushing the push rod 3 to make the top block 4 push the part along the guide groove to the bending position of the equipment, the bending equipment can perform the bending operation.

[0019] Finally, by pulling back the push rod 3, the next part rough material located in the blanking mechanism will fall down and fall into the guide groove.

[0020] The beneficial effects of the present invention are:

[0021] (1) Modular design: The feeding device adopts a modular design. The number of feeding units can be replaced and adjusted according to the number of parts to be processed and the efficiency requirements to meet the required number of single bends.

[0022] (2) Universal design: The blanking mechanism and guide mechanism adopt an adjustable design, and each part can be quickly adjusted as needed to meet the processing needs of parts of different shapes, sizes and thicknesses.

[0023] (3) High-precision guiding: The design of the guiding mechanism fully considers the high-precision requirements of aviation sheet metal parts. The positioning accuracy of parts during the feeding process is ensured through precision-machined guide plates and adjustable guide grooves.

[0024] (4) The structure is easy to maintain: All components within the unit are designed to be detachable, and the components that require maintenance and repair can be replaced according to usage.

[0025] (5) Humanized operation: The feeding device is easy to operate and the operator can complete the setting and adjustment of the feeding mechanism through simple operations. The operation difficulty is low, which improves production efficiency compared with traditional methods.

[0026] (6) Safer operation: During the traditional method of bending tool mold closing, the operator needs to hold the parts for a long time and go through the mold closing process, which poses certain safety hazards. The invention can replace the hand-held operation, which is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] ① Design of base 2: Base 2 is made of lightweight materials with guaranteed strength, and most of the base is made of T-state aluminum alloy. The height of base 2 is kept level with the height of the bending knife slot of the bending equipment so that the parts can be sent to the top of the knife slot. As the main structure of the entire device, base 2 connects the mechanical operation of each component through the base. The base 2 consists of the ball bearings between the top plate and the base in the feeding mechanism, and the limit sliders of the guide plates on both sides of the guide mechanism 1.

[0039] ② Design guide mechanism 1: It consists of 2 precision machined and assembled guide plates, with a precise guide groove formed between the guide plates to ensure the stability and accuracy of the parts during feeding. The guide plate adopts an adjustable design and can be fine-tuned according to the specific shape of the parts to improve the processing accuracy. The guide plate and the base move horizontally through the slider.

[0040] ③ Design of feeding mechanism: It is composed of a push rod 4 and a movable ejector block 3.

The size and shape of the movable ejector block 3 can be customized according to the specific needs of the parts, enriching the richness of the machinable parts. This embodiment adopts a semicircular universal ejector block. The movable ejector block 3 is made of high-strength steel, and the surface is specially treated to reduce friction and improve feeding efficiency.

[0041] ④ Design of the pressing mechanism 5: The advanced slider connecting rod and roller design are adopted, and the reasonable layout of the rollers can effectively prevent the parts from derailing during the feeding process. The design of the pressing mechanism fully considers the characteristics of aviation sheet metal parts, and can improve the feeding stability while ensuring the processing accuracy.

[0042] ⑤ Design of the blanking mechanism 7: The blanking mechanism 7 is used to drop the stacked parts into the guide groove one by one through the reciprocating motion of the feeding mechanism. The blanking mechanism 7 includes limit struts 6 in four directions. The limit struts 6 can adjust the position. The limit struts 6 in the guiding direction also limit the feeding to ensure that only one piece is fed each time. The thickness of the plate allowed to pass can be adjusted by the gasket to increase versatility.

[0043] ⑥ The feeding mechanism, the guide mechanism 1, the pressing mechanism 5 and the blanking mechanism 7 are used in a group around the joint arrangement, and are easy to disassemble and install, and adopt a modular design.
