[0027] Refer to Figure 1 As shown, the present utility model provides a technical solution: a PIN needle trimming and bending mechanism, including a chassis 1 and several PIN needle bodies 4. A bending structure 2 is provided on the surface of the chassis 1. By setting the bending structure 2, PIN needles of different sizes can be bent, so that workers do not need to replace different PIN needle trimming and bending mechanisms, thereby improving production efficiency and saving production time. A fixing structure 3 is provided on the surface of the chassis 1. By setting the fixing structure 3, the PIN needle trimming and bending mechanism can be limited on the processing table, so that when the worker uses the PIN needle trimming and bending mechanism, the PIN needle trimming and bending mechanism will not shake, facilitating the worker to use the PIN needle trimming and bending mechanism.
[0028] Next, specifically describe the specific settings and functions of its bending structure 2 and fixing structure 3.
[0029] Refer to Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment: the bending structure 2 includes a plurality of limiting grooves 203, all of which are provided on the surface of the base frame 1. A plurality of PIN pin bodies 4 are slidably connected to the inner walls of the plurality of limiting grooves 203. A screw 201 is connected to the inner thread of the base frame 1. A pressure plate 206 is rotatably connected to the surface of the screw 201. A first connecting plate 204 is fixedly mounted on the surface of the base frame 1. Two hydraulic rods 205 are fixedly mounted on the lower surface of the first connecting plate 204. The output ends of the two hydraulic rods 205 are fixedly mounted to a second connecting plate 207. Two lifting rods 202 are slidably inserted into the interior of the base frame 1. The lower ends of the two lifting rods 202 are fixedly connected to the pressure plate 206. The lifting rods 202 can limit the pressure plate 206 so that the pressure plate 206 does not shake when sliding up and down. The inner walls of several limit slots 203 are slidably connected with a push rack 208, and two card rods 209 are fixedly inserted inside the push rack 208. A push plate 210 is fixedly installed on the end of the card rod 209 away from the push rack 208. Two support holes 212 are provided on the surface of the base frame 1. The inner walls of the support holes 212 are slidably connected with the card rod 209. The push plate 210 is slid, and the sliding of the push plate 210 drives the card rod 209 to slide. The sliding of the card rod 209 drives the push rack 208 to slide. During the sliding process of the push rack 208, the push rack 208 can push out the PIN needle on the inner wall of the limit slot 203. Two elastic pads 211 are fixedly installed on the surface of the base frame 1. The cross-section of the elastic pad 211 is "U"-shaped. When the push plate 210 slides a certain distance, the surface of the push plate 210 squeezes the elastic pad 211. At this time, the push plate 210 is stuck by the elastic pad 211, so that the push plate 210 cannot slide and the push frame 208 cannot slide either, thereby achieving the effect of limiting the sliding of the push frame 208.
[0030] Reference Figure 2 As shown, specifically, the fixed structure 3 includes a balance plate 31, the surface of which is fixedly connected to the base frame 1. Two guide rods 33 are slidably inserted into the interior of the base frame 1, and contact plates 34 are fixedly mounted on the surfaces of the two guide rods 33. A threaded rod 32 is threadedly connected to the interior of the base frame 1, and a circular plate 35 is fixedly mounted on the surface of the threaded rod 32, and the surface of the circular plate 35 abuts against the contact plate 34. Four mounting plates 36 are fixedly mounted on the surface of the circular plate 35, and the four mounting plates 36 are evenly distributed on the surface of the circular plate 35. When the mounting plates 36 are rotated, the mounting plates 36 simultaneously drive the circular plate 35 to rotate, thereby achieving the effect of assisting the rotation of the circular plate 35.
[0031] Working principle: when PIN pins of different sizes need to be bent, first place the PIN pin on the limiting groove 203, then turn the screw 201, the screw 201 moves downward with the help of the thread, and the screw 201 drives the pressure plate 206 to move while moving. After the pressure plate 206 moves a certain distance, the surface of the pressure plate 206 squeezes the PIN pin, and the PIN pin is limited on the limiting groove 203. Then start the hydraulic rod 205, and the conveying end of the hydraulic rod 205 moves downward. When the hydraulic rod 205 moves, it drives the second connecting plate 207 to move. During the movement of the second connecting plate 207, the second connecting plate 207 squeezes the PIN pin, causing the PIN pin to bend. After the PIN pin is bent, turn the screw 20 1. The screw 201 moves upward with the help of the thread, and the screw 201 moves while driving the pressure plate 206 to move. After the pressure plate 206 moves a certain distance, the surface of the pressure plate 206 no longer squeezes the PIN needle, and then the push plate 210 is slid, and the push plate 210 slides in the direction close to the PIN needle. The push plate 210 slides while driving the card rod 209 to slide, and the card rod 209 slides while driving the push frame 208 to slide. During the sliding process of the push frame 208, the push frame 208 can push the PIN needle out of the inner wall of the limit groove 203. By setting the bending structure 2, PIN needles of different sizes can be bent, so that the staff does not need to replace different PIN needle trimming and bending mechanisms, thereby improving production efficiency and saving production time.
[0032] When the PIN needle trimming and bending mechanism is used on the processing table, first make the balance plate 31 close to the edge of the processing table, and then rotate the circular plate 35 through the mounting plate 36. When the circular plate 35 rotates, the threaded rod 32 is driven to rotate, and the threaded rod 32 moves toward the direction of the base frame 1 with the help of the thread. When the threaded rod 32 moves, it drives the contact plate 34 to move. After the contact plate 34 moves a certain distance, the surface of the contact plate 34 squeezes the other edge of the processing table. At this time, the base frame 1 is limited on the processing table, and the PIN needle trimming and bending mechanism is also limited on the processing. By setting the fixed structure 3, the PIN needle trimming and bending mechanism can be limited on the processing table, so that when the staff uses the PIN needle trimming and bending mechanism, the PIN needle trimming and bending mechanism will not shake, which is convenient for the staff to use the PIN needle trimming and bending mechanism.
