Description

Technical Field

[0001] This utility model relates to the technical field of dovetail clip processing equipment, and in particular to a device for producing dovetail clips. Background Technology

[0002] A swallowtail clip is a type of stationery clip made of metal, used to hold a stack of documents together. It is also known as a phoenix tail clip or ticket clip. It has a movable handle, which makes it easy to hold the paper tightly and prevents it from falling off. It is made of pure metal, is easy to disassemble, can be reused, and is environmentally friendly and durable.

[0003] Traditionally, the clamp body of a dovetail clip is formed by stamping with a stamping machine. Specifically, a base is set on one side of the placement seat on the stamping machine body. The base is equipped with a conveyor roller driven by a motor. The raw material plate is wound on an independent winding frame. Its first end is pulled by personnel and conveyed to the placement seat through the conveyor roller on the base. Then, the stamping head presses down and works with the mold on the placement seat to stamp the raw material plate into the initial clamp body. Then, the clamp body is pushed out of the base by the pushing component. The storage box placed outside the base can then be used for unified storage.

[0004] However, the number of raw material plates on the winding rack is limited. After each use, personnel need to manually place a new raw material plate, and then pull the first end of the raw material plate on the winding rack to the conveyor roller on the base so that it passes through the conveyor roller and is driven by the conveyor roller. The whole process is quite cumbersome and the replacement of raw material plates is not convenient. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a device for producing dovetail clips.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dovetail clip production device, including a stamping machine body and a base at one end thereof, a conveying roller driven by a motor is provided on the base, an extension platform is provided on the side of the base away from the stamping machine body, a guide rod is provided on the extension platform, an infrared sensor is provided at the end of the extension platform facing the base, a translation component is provided on the upper side of the extension platform along its length direction, and a push rod is connected to the movable end of the translation component.

[0007] Preferably, a limit rod is provided on the expansion platform along its length, and the limit rod is supported on the expansion platform by a side plate.

[0008] Preferably, the translation component includes a second motor mounted on one end of the extension platform and a ball screw connected to its output shaft. A slider is slidably mounted on the ball screw, and one end of the push rod is rotatably connected to the slider.

[0009] Preferably, a limiting plate is slidably provided on the slider, and a top fixing bolt is screwed to one end of the limiting plate.

[0010] Preferably, a cylinder is provided between the expansion platform and the base. A driving plate is provided at the top of the piston rod of the cylinder. A connecting plate is rotatably connected to the lower side of the driving plate. A pressure block is rotatably connected to the connecting plate through a rotating rod. A guide block is provided on the end of the base facing the expansion platform. A guide groove is provided on the side of the guide block facing the pressure block. One end of the rotating rod is slidably connected to the guide groove.

[0011] Preferably, a friction pad is provided on the lower side of the pressure block.

[0022] like Figures 1 to 4 As shown, a device for producing dovetail clips includes a press body 1 and a base 2 located at the left end. A conveyor roller 4 driven by a motor 3 is mounted on the base 2. An auxiliary roller (not shown in the figure) parallel to the conveyor roller 4 is mounted on the right end of the conveyor roller 4. An extension platform 5 is mounted on the side of the base 2 away from the press body 1. The upper side of the extension platform 5 is flush with the upper side of the base 2, and the extension platform 5 and the base 2 are horizontally and vertically arranged. A guide rod 6 is mounted on the extension platform 5 along its length, allowing personnel to place the wound raw material plates one by one. An infrared sensor 7 is installed on the guide rod 6 at one end of the expansion platform 5 facing the base 2. A ball screw 12 is installed on the upper left side of the expansion platform 5 along its length. One end of the ball screw 12 is connected to a motor 3. A slider 13 is slidably installed on the ball screw 12. A push rod 8 is rotatably connected to the right end of the slider 13. An L-shaped limiting plate 14 is horizontally slidable on the upper side of the slider 13. A top fixing bolt 15 is screwed to the lower end of the limiting plate 14. The purpose of this is to fix the position of the limiting plate 14 on the slider 13.

[0023] A limiting rod 9 is horizontally installed on the expansion platform 5 between the guide rod 6 and the base 2. The limiting rod 9 is installed along the length of the expansion platform 5, and one end of it is supported on the expansion platform 5 by the side plate 10. Its purpose is to allow the first end of the raw material plate sleeved on the guide rod 6 to pass through. The limiting rod 9 works with the upper side of the expansion platform 5 to limit the raw material plate sleeved on the guide rod 6, so as to prevent the wound raw material plate from becoming too loose.

[0024] A cylinder 16 is vertically installed above the infrared sensor between the expansion platform 5 and the base 2. The piston rod of the cylinder 16 points downward and is connected to a drive plate 17. A connecting plate 18 is rotatably connected to the lower side of the drive plate 17. The lower end of the connecting plate 18 is connected to a pressure block 20 via a rotating rod 19. A friction pad 23 is fixed to the lower side of the pressure block 20. The purpose of the friction pad 23 is to increase the contact friction between the pressure block and the raw material plate. A guide block 21 is fixed on the end of the base 2 facing the expansion platform 5. An arc-shaped guide groove 22 is provided on the side of the guide block 21 facing the pressure block 20. One end of the rotating rod 19 is slidably connected to the guide groove 22. The purpose of the rotating rod 19 is to allow the pressure block 20 to move along the guide direction of the guide groove 22.

[0025] When manufacturing the clamp body for the dovetail clip, first place the wound raw material plates one by one onto the guide rod 6, such as... Figure 1 As shown, the first end of each set of raw material plates passes under the limiting rod 9, and then the push rod 8 is placed horizontally on the guide rod 6. The limiting plate 14 is located above the connection between the push rod 8 and the slider 13. The top bolt 15 is tightened, and the rotation of the push rod 8 is restricted by the limiting plate 14. The cylinder 16 extends and pushes the driving plate 17 to move down. The driving plate 17 moves down and pushes the pressure block 20 through the connecting plate 18. Since the driving plate 17 and the connecting plate 18 are rotatably connected, and the connecting plate 18 is rotatably connected to the pressure block 20 through the rotating rod 19, the pressure block 20 will be driven to move along the guiding direction of the guide groove 22 during the downward movement, that is, it moves down and pushes forward in an arc. The friction pad 23 has a certain degree of flexibility, so it can pull the first end of the raw material plate located directly above the infrared sensor to move forward and enter the conveying roller 4. The conveying roller 4 is driven by the motor 3 to pull the first end of the raw material plate and then enter the stamping area in the stamping machine body 1. After the cylinder 16 completes the downward movement, it will reset and move upward.

[0026] When the raw material plate directly above the infrared sensor is used up, and the infrared sensor detects no obstruction above, motor 11 starts to rotate forward. It drives slider 13 through ball screw 12, slider 13 drives push rod 8, and push rod 8 pushes the raw material plate wound on guide rod 6, moving the raw material plate closest to base 2 to the opposite position of base 2. The first end of this raw material plate begins to block the infrared sensor and is also located directly below pressure block 20. At this time, cylinder 16 starts, piston rod extends, and indirectly pushes the first end of the raw material plate to the conveyor roller 4 for contact with it through pressure block 20.

[0027] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
