Description

Technical Field

[0001] The invention belongs to the technical field of pipe punching equipment, and in particular relates to a full-automatic punching machine for an open ring end. Background Art

[0002] The existing double ring structure is often used for decoration in window guards and guardrails. The existing double ring structure is divided into two welding structures. One is to weld an open ring into a whole ring first, and then the other ring is divided into two arc parts. One arc part less than 180° is welded inside the whole ring, and the other arc part greater than 180° is welded outside the whole ring. This method of double ring processing is complicated to operate, has low production efficiency and high cost, and has been basically eliminated.

[0003] The other is two open rings, which are inserted into each other from their respective openings and then welded into a double ring structure. In this type of double ring processing, since the two ends of the open ring are flat, when it is welded to the side of another ring structure, it is either spot welding, which is not reliable and it is difficult to ensure the production quality of the double ring structure. Or it is full welding, which is time-consuming and material-consuming, and difficult to polish after welding, with high production costs and unsightly appearance. In order to better realize the welding of the double ring structure, some people have proposed to process the end of the open ring into an arc shape to facilitate contact and welding with the side of another ring structure and improve the quality of the product. However, there is no special machinery for processing, and manual processing is required, which has high labor intensity for workers, low production efficiency and high production costs.

The feed guide rail 2, the oil cylinder 4, the mold 5, the two clamping cylinders 6, the pulling cylinder 8 and the withdrawing cylinder 9 are fixedly mounted on the frame 1. The square cross-section of the feed guide rail 2 is I-shaped, and an open ring is hung on the feed guide rail 2. The discharge end of the feed guide rail 2 is slightly lower than the feed end, and a baffle 11 is provided at the discharge end. As shown Figure 3-4As shown, the baffle 11 is provided with two slides 12 (the number of slides 12 may be more than two), and the two slides 12 are respectively sleeved on two guide shafts 13, the guide shafts 13 are arranged vertically, and the upper ends of the guide shafts 13 are fixed on the mounting plate 14. A spring 15 is sleeved on the guide shaft 13, and the two ends of the spring 15 are respectively connected to the slide 12 and the mounting plate 14. The mounting plate 14 is fixedly mounted on the frame 1. The bottom of the baffle 11 is provided with two ear plates 111, and the ear plates 111 are arranged perpendicular to the baffle 11, and the distance between the two ear plates 111 is greater than the diameter of the open ring. A pad 112 is provided on the side of the baffle 11 facing the feed end of the feed guide rail. The vibrator 3 is fixedly mounted on the feed guide rail 2; the vibrator 3 can make the feed guide rail 2 vibrate, thereby making the open ring hanging on the feed guide rail 2 move toward the discharge end.

[0021] The oil cylinder 4 is fixed directly above the mold 5. A punching knife guide hole is provided at the center of the mold 5. A feed trough and a feed hole are provided on both sides of the mold 5. The feed trough is connected to the discharge end of the feed guide rail 2. The feed hole is located in the feed trough and is connected to the punching knife guide hole. The punching knife is placed in the punching knife guide hole, and the upper end of the punching knife is connected to the piston rod of the oil cylinder 4. Figure 5 , 6 As shown, the punching knife comprises a knife body 121 with a square cross section and two punching blocks 122. The two punching blocks 122 are symmetrically arranged on the knife body 121. The side surfaces of the punching blocks 122 are cylindrical side surfaces. The punching blocks 122 are arranged corresponding to the feed holes of the mold.

[0022] The two clamping cylinders 6 are arranged corresponding to the feed holes on the mold 5 and are respectively located on both sides of the mold 5. The pulling cylinder 8 is arranged parallel to the feed slot on the mold 5, and the plate pulling cylinder 10 is connected to the piston rod of the pulling cylinder 8; the plate pulling cylinder 10 is arranged vertically, and a pulling plate 101 is installed on the piston rod of the plate pulling cylinder 10, as shown in FIG. Figure 7 As shown, the top of the pull plate 101 corresponds to the two ear plates at the bottom of the baffle 11, and a bearing frame 102 is respectively provided. A bearing 103 is installed on the bearing frame 102, and the radius of the bearing 103 is smaller than the diameter of the open ring tube. The pull plate 101 is arranged parallel to the baffle 11. The bearing 103 on the pull plate 101 cooperates with the two ear plates 111 at the bottom of the baffle 11 to lift the baffle 11, so that an open ring enters the feed groove, and then the pull plate 101 pulls the open ring, and positions the open ring together with the end face of the material withdrawal cylinder. The two clamping cylinders 6 clamp the open ring, so that the two ends of the open ring enter the feed hole. The material withdrawal cylinder 9 is arranged parallel to the feed groove on the mold 5, and is located above the pull cylinder 8; the finger cylinder 7 is fixedly installed at the end of the piston rod of the material withdrawal cylinder 9.

[0023] The frame 1 is provided with a push rod 16, which is arranged parallel to the feed groove on the mold 5. The finger cylinder 7 is provided with a push rod hole corresponding to the push rod. The push rod 16 can pass through the push rod hole to push down the open ring on the finger cylinder 7 that has not been removed in time.

[0024] When the present invention is used, firstly, a plurality of open rings are hung on the feed guide rail 2, and the present invention is turned on. The vibrator 3 vibrates, so that the open rings hung on the feed guide rail 2 move toward the discharge end and are blocked by the baffle 11 at the discharge end. Then, the pulling cylinder 8 extends, so that the plate pulling cylinder 10 moves toward the baffle 11. After moving into position, the piston rod of the plate pulling cylinder 10 extends, so that the plate pulling 101 moves upward, and the bearing 103 at the top of the plate pulling 101 presses against the ear plate 111 at the bottom of the baffle 11. While lifting the baffle 11, an open ring is placed between the plate pulling 101 and the end plate of the piston rod of the material withdrawal cylinder 9. The piston rod of the plate pulling cylinder 10 retracts, pulling the open ring, so that the two ends of the open ring enter the two feed grooves of the mold respectively. After the piston rod of the plate pulling cylinder 10 retracts into position, the two ends of the open ring are aligned with the two feed holes of the mold 5; then the two clamping cylinders act to squeeze the open ring, so that the two ends of the open ring enter the two feed holes of the mold 5 respectively. Then the oil cylinder moves, driving the punch downward to punch the open ring. After punching, the finger cylinder 7 moves, and the two fingers of the finger cylinder 7 support the open ring, so that the two ends of the open ring come out of the two feeding holes of the mold 5, and then the piston rod of the material return cylinder 9 retracts. During the retraction process of the piston rod of the material return cylinder 9, the two fingers of the finger cylinder 7 are reset, and the open ring falls. If the two fingers of the finger cylinder 7 are not reset; during the retraction process of the piston rod of the material return cylinder 9, the push rod 16 pushes the open ring down, completing the whole punching process.
