Description

Technical Field

[0001] The utility model relates to the technical field of screw processing equipment, in particular to a trimming machine for screw trimming. Background Art

[0002] Screws are widely used in many fields such as machinery, construction, electronic appliances, etc. They usually consist of two parts: the head and the screw. The head is designed in various shapes such as hexagonal, slotted, cross slot, etc. The screw part has threads and can fit tightly with nuts or other workpieces with internal threads.

[0003] The eyebolt combines the fastening function of the screw with the load-bearing property of the eyebolt. By attaching a eyebolt to the screw, the screw can safely connect and support heavy objects. After processing, the eyebolt needs to be trimmed to ensure that the edge of the screw is flat and smooth, eliminate burrs and sharp angles, and prevent scratches on surrounding objects or personal injury during use. Therefore, the Chinese utility model patent disclosed by publication number CN208276009U: eyebolt trimming device, the application provides two grooves, and the ends of the long grooves in the grooves are staggered with each other, so that the two eyebolts can be trimmed on one side to improve work efficiency, and an elastic member and a support plate are provided in the groove, and the support plate is used to support The eye screw entering the groove can prevent the eye screw from tilting when entering the groove, resulting in uneven cutting. When the eye screw is cut through this application, the eye screw is first positioned by arranging an elastic plate and a support plate in the groove, and the eye screw with completed cutting is supported to facilitate material removal. However, since this operation step still requires manual placement of the eye screw, the cutting efficiency of the eye screw cannot be further improved. In addition, after the eye screw is cut through this application, the removed waste will remain in the groove and on the support plate, thereby affecting the subsequent placement of the eye screw, and the position needs to be continuously cleaned, which increases the cumbersomeness of cutting the eye screw.

[0026] like Figure 2-Figure 4As shown, three mounting holes 14 are provided at the bottom of the trimming die 10, and connecting screws 15 are inserted and installed in the mounting holes 14. Three first sliding grooves 16 are provided at the top of the trimming die 10. An embedding groove 17 is provided at the trimming die 10 between the two first sliding grooves 16. A second sliding groove 18 is also provided at the top of the trimming die 10 on one side of one of the embedding grooves 17. With the help of the first sliding grooves 16, a guide can be provided for the horizontal movement of the push plate 13, and the embedding groove 17 can limit the position of the trimming of the metal ring. The top plate 11 is inserted and installed in the corresponding embedding grooves 17, and the top of the connecting screw 15 is threadedly connected to the bottom of the top plate 11. The connecting screw 15 located between the top plate 11 and the bottom of the embedding groove 17 is sleeved with a first compression spring 19. A second compression spring 20 is also fixedly installed at the bottom of the top plate 11 on one side of the first compression spring 19. Through the arrangement of the top plate 11 in conjunction with the first compression spring 19 and the second compression spring 20, the metal ring can be ejected after the trimming process is performed on the metal ring, which is convenient for blanking.

[0027] like Figure 2-Figure 6 As shown, a front loading plate 27 is fixedly installed on the front side of the trimming die 10, and a cylinder 28 is fixedly installed on the front side of the front loading plate 27. The cylinder 28 is connected to an external pump station through a pipeline. With the help of the setting of the cylinder 28, the push plate 13 can be horizontally moved on the top of the trimming die 10. A plurality of storage cavities 21 are provided in the material storage box 12. Ear seats 22 are fixedly installed on both sides of the material storage box 12.

One side of the bracket 26 is fixedly connected to the output end of the cylinder 28. Through the horizontally movable push plate 13, the push plate 13 can cooperate with the push groove 31 to push the eye screw in the storage box 12 onto the top plate 11, and at the same time, the eye screw with trimming completed on the top plate 11 can be unloaded. A trimming groove 29 is provided at the bottom of the trimming punch 9, and a trimming column 30 is fixedly installed at the top center position in the trimming groove 29.

[0028] It should be noted that the utility model is a trimming machine for screw trimming. When trimming the eyebolts, the eyebolts can be first placed in the storage cavity 21 in the storage box 12 for temporary storage, which can ensure that the feeding and pushing directions of the eyebolts are correct. Then, the external pump station can be started by the external controller, so that the output end of the cylinder 28 pushes the bracket 26 to move to one side, so that the pushing groove 31 located below the storage box 12 pushes the corresponding eyebolt to one side, so that three eyebolts can be pushed at the same time. The push plate 13 is moved to the corresponding embedding groove 17 and placed on the top plate 11 in the embedding groove 17. Since there is a certain height difference between the top of the top plate 11 and the top of the embedding groove 17, the eye screw can be automatically positioned and fall on the top plate 11. Then, the output end of the cylinder 28 resets and pulls back the push plate 13 through the bracket 26, so that the eye screw at the bottom of the three storage cavities 21 in the material storage box 12 falls into the push groove 31. At this time, the stamping mechanism 3 moves the top seat 7 up and down on the two guide pillars 6, so that the top seat 7 drives the mold The plate 8 moves down, so the three trimming punches 9 at the bottom of the template 8 are synchronously inserted into the corresponding embedding grooves 17, so that the trimming grooves 29 and the trimming columns 30 in the trimming punches 9 are used to trim the outer and inner sides of the eye of the eye screw, and then the stamping mechanism 3 drives the top seat 7 to move up, so that the top seat 7 can drive the trimming punches 9 to disengage from the embedding grooves 17 through the template 8. At this time, the top plate 11 is pushed up by the rebound force of the first compression spring 19 and the second compression spring 20, so that the top plate 11 can lift the eye screw with the trimmed edges. The nail is ejected. At this time, the cylinder 28 pushes the push plate 13 to one side, so that the push plate 13 pushes the untrimmed eye screw through the pushing groove 31 to eject the trimmed eye screw from the top plate 11 and unload it through the unloading groove on the side of the operating table 2. At the same time, the push plate 13 pushes the untrimmed eye screw onto the top plate 11 through the pushing groove 31. Synchronously, the external pump station conveys gas into the push plate 13 in sequence, so that the gas can be ejected through the nozzle 23 on one side of the pushing groove 31, and the debris on the top plate 11 can be blown away.
