Description

Technical Field

[0001] The invention relates to the technical field of nut plates, and in particular to a stamping and forming device for nut plates. Background Art

[0002] Nutplates are an important component used extensively in industries such as aerospace, automotive and construction to securely and safely fasten different parts together.

[0003] Nut plates require different steps of operation in production. The plate material for making the nut plates needs to be stamped and formed. During the stamping process of the existing stamping and forming device, when the punch of the stamping and forming device stamps the nut plate, the nut plate is deformed by the stamping. During the deformation process, the outer paint and material on the surface may be squeezed and fall onto the stamping and forming device.

[0004] The fallen debris will affect the subsequent placement of the nut plate, thereby affecting work efficiency, so a corresponding cleaning structure needs to be set up. Summary of the invention

[0005] The object of the present invention is to provide a stamping and forming device for a nut plate to solve the problems raised in the above-mentioned background technology.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a punching and forming device for a nut plate, comprising a frame and a punching assembly, wherein a plurality of holes are arranged in the middle of the frame, a punching assembly is installed on the top of the frame, and the punching assembly cooperates with the holes to punch the nut plate;

[0008] A transmission assembly is installed at the bottom of the frame, and two ends of the frame are rotatably connected to two rollers, and the transmission assembly is connected to the rollers and drives the rollers;

[0009] The two sides of the frame are respectively provided with moving grooves, a cleaning component is provided between the two moving grooves, and the cleaning component moves along the path of the moving groove;

[0010] A plurality of corner blocks are installed on the transmission assembly. When the transmission assembly is running, the corner blocks are driven to move. During the movement of the corner blocks, the cleaning assembly is pushed. During the movement of the cleaning assembly, the middle upper surface of the frame is cleaned.

[0011] Discharge gaps are respectively arranged at both ends of the frame, and collection boxes for collecting dust are respectively installed at the bottoms of both ends of the frame, and the discharge gaps penetrate the frame and extend to the collection boxes.

[0012] The purpose of the above arrangement is to place the nut plate in the middle of the frame, and the stamping assembly is installed on the top of the frame. There are several holes in the middle of the frame. When the nut plate is stamped, the stamping assembly and the holes cooperate with each other to realize the stamping operation of the nut plate.

[0013] The transmission assembly is installed at the bottom of the frame and connected to the rollers at both ends of the frame. When the transmission assembly is running, it can drive the rollers to rotate. The rotation of the rollers rubs against the lower surface of the nut plate to move and adjust the nut plate.

[0014] A number of corner blocks are installed on the transmission assembly. When the transmission assembly is running, the corner blocks will move with the transmission assembly. Moving grooves are arranged on both sides of the frame. The cleaning assembly is located between two positioning rods and can move along the moving grooves. The corner blocks will push the cleaning assembly during the movement. After being pushed by the corner blocks, the cleaning assembly moves along the moving grooves, and cleans the middle upper surface of the frame during the movement.

[0015] There are discharge gaps at both ends of the frame. The waste generated during the stamping process can be discharged through the discharge gap when being pushed by the cleaning assembly.

[0016] Collection boxes are installed at the bottom of both ends of the frame. The discharge gap runs through the frame and extends to the collection box. Dust and other impurities generated during the cleaning process will enter the collection box through the discharge gap, thereby realizing dust collection.

[0017] Furthermore, the stamping assembly includes a cylinder, which is installed on the top of the frame. The output end of the cylinder passes through the top of the frame. A flat plate is installed on the bottom of the cylinder, and a plurality of columnar protrusions are installed on the lower surface of the flat plate, and a plurality of the columnar protrusions correspond to the holes.

[0018] The purpose of the above setting is that the cylinder in the stamping assembly is installed on the top of the frame. When the cylinder is working, its output end pushes the plate to move downward. Because a number of columnar protrusions are installed on the lower surface of the plate, and the columnar protrusions correspond to the holes, when the plate moves downward, the columnar protrusions can perform stamping operations on the nut plate through the holes.

[0019] Furthermore, two sides of the plate penetrate through two sides of the frame and slide, and second springs are respectively arranged between the two sides of the plate and the two sides of the frame.

[0020] The purpose of the above arrangement is that the two sides of the plate pass through the two sides of the frame and can slide, and a second spring is arranged between the two sides of the plate and the two sides of the frame.

The first spring is sleeved on the outer wall of the positioning rod, and the first spring is located between the lower surface of the flat plate and the upper surface of the circular plate at the bottom of the positioning rod.

[0022] The purpose of the above-mentioned setting is that the positioning rod passes through the flat plate and is slidably connected. There are circular plates on the top and bottom of the positioning rod. The first spring is sleeved on the outer wall of the positioning rod and is located between the lower surface of the flat plate and the upper surface of the circular plate at the bottom of the positioning rod. During stamping, the positioning rod can position the nut plate, and the first spring plays a role of buffering and auxiliary positioning to prevent the nut plate from being offset during the stamping process and affecting the stamping effect.

[0023] Furthermore, the cleaning assembly includes a long shaft and a roller brush, the two ends of the long shaft are respectively slidably connected to the inner sides of the two movable grooves, the roller brush is installed on the outer wall of the long shaft, the two ends of the long shaft are respectively installed with convex blocks, the convex blocks are located on the inner side of the frame, and the two ends of the long shaft are respectively installed with round blocks, the round blocks are located on the outer side of the frame.

[0024] The purpose of the above-mentioned arrangement is that the two ends of the long shaft of the cleaning component are slidably connected on the inner side of the two movable grooves, and the roller brush is installed on the outer wall of the long shaft. When the transmission component is running, the corner block will push the cleaning component, and the convex blocks at both ends of the long shaft are on the inner side of the frame, and the round blocks are on the outer side of the frame. They play a certain role in limiting and assisting stability on the long shaft to prevent one end from offsetting and affecting the movement during the movement of the long shaft. During the movement of the long shaft, the convex block moves in contact with the upper surface of the middle part of the frame, and pushes the nut plate in front during the movement.

[0025] Furthermore, the outer sides of both ends of the flat plate are respectively connected with toggle rods, and the lower surface of the toggle rods is provided with grooves, and the grooves are located above the roller brush.

[0026] The purpose of the above arrangement is that the lower surface of the toggle rod on the outside of both ends of the flat plate has a groove and is located above the roller brush. During the stamping process, the groove of the toggle rod pushes the roller brush downward, and the roller brush moves along the moving groove through the long axis.

Several corner blocks are evenly installed on the outer wall of the transmission belt. When the transmission belt rotates driven by the driving wheel, the corner blocks move with the transmission belt. During the movement, the corner blocks can push the cleaning assembly to move, thereby realizing the cleaning of the upper surface of the middle part of the frame.

[0032] Furthermore, a demoulding structure is installed inside the hole, and the demoulding structure includes a third spring and a sliding block. The third spring is installed on the bottom inner wall of the hole, and the sliding block is connected to the top of the third spring. The sliding block is slidably connected to the inner wall of the hole.

[0033] The purpose of the above-mentioned setting is that in the demolding structure inside the hole, the third spring is installed on the inner wall of the bottom of the hole, and the sliding block is connected to the top of the third spring and slidably connected to the inner wall of the hole. After the stamping is completed, when the stamped nut plate needs to be demolded from the hole, the elastic force of the third spring will push the sliding block to move upward, thereby assisting the demolding of the nut plate.

[0034] Furthermore, the roller is mounted on the outer wall of the rotating shaft, and the top of the roller is flush with the middle upper surface of the frame.
