The position of the wire inlet device 4 is arranged near the wire outlet of the last forming wire pressing machine 1, which is beneficial for the processing staff in charge of processing the wire rods entering the wire and the formed I-shaped code wire rods.

As shown in fig. 8 to 10, the thread feeding device 4 comprises a thread feeding wheel 41 for guiding the metal thread 5, a mounting rack 42 for mounting the thread feeding wheel 41, a bracket 43, a threading ring 44, a thread missing sensor 46 and an alarm module, wherein the bracket 43 is mounted above the mounting rack 42, a rod body 441 extends on the threading ring 44, the rod body 441 penetrates through the bracket 43, the threading ring 44 slides on the support 43 through the rod body 441 along the length direction of the rod body 441, the mounting frame 42 is further provided with a wire guide hole 421, the threading ring 44 and the wire inlet position of the wire inlet wheel 41 are located on the same straight line, an elastic piece 45 used for driving the threading ring 44 to deviate from the original position is further arranged between the support 43 and the rod body 441, the thread-missing sensor 46 is electrically connected with the alarm module, the thread-missing sensor 46 is used for sensing whether the threading ring 44 deviates from the original position or not, and the alarm module is started when the threading ring 44 is detected to deviate. The home position refers to a position where the threading ring 44 and the thread guiding hole 421 are on the same straight line as the thread feeding position of the thread feeding wheel 41.

Specifically, taking one of the placing modes as an example, the bracket 43 is mounted on the mounting frame 42 at a position close to the wire feeding wheel 41, the threading ring 44 is located right below the wire feeding position of the wire feeding wheel 41, and the wire guiding hole 421 is located right below the threading ring 44, so that the wire guiding hole 421, the threading ring 44 and the wire feeding position of the wire feeding wheel 41 are located on the same vertical straight line. The length direction of the rod body 441 is selected to be perpendicular to the wheel surface of the wire-feeding wheel 41, and the elastic member 45 is a compression spring 324. One end of the compression spring 324 is connected with the end of the rod body 441 far away from the end of the threading ring 44, and the other end of the compression spring 324 is connected with the bracket 43, so that the function of driving the threading ring 44 to deviate from the original position through the compression spring 324 is realized.

A buffer base 442 is additionally disposed at an end of the rod 441 away from the threading ring 44, the buffer base 442 is a convex edge protruding from the rod 441, and a convex ring engaged with the buffer base 442 is disposed on the bracket 43 to prevent the rod 441 from separating from the bracket 43. The thread missing sensor 46 is arranged on the side face of the support 43 and is aligned with one end, away from the threading ring 44, of the rod body 441, when the rod body 441 is pushed, the thread missing sensor 46 can sense the rod body 441, when the rod body 441 is pushed out, the thread missing sensor 46 cannot sense the existence of the rod body 441, and therefore the alarm module is triggered to notify workers.

Since the length direction of the rod 441 is perpendicular to the wheel surface of the thread feeding wheel 41 in this embodiment, the direction for driving the threading ring 44 to deviate from the original position is perpendicular to the wheel surface of the thread feeding wheel 41.

The wire guide plate 422 can be additionally arranged below the mounting frame 42, the wire guide plate 422 is arranged in parallel with the mounting frame 42, a certain distance is reserved between the wire guide plate 422 and the bottom of the mounting frame 42, the wire guide plate 42 is fixedly connected with the bottom of the mounting frame 42, a through hole 423 is formed in the wire guide plate 422, and the through hole 423 is positioned on the same straight line with the wire guide hole 421, the threading ring 44 and the wire inlet position of the wire inlet wheel 41. The main purpose of this is to facilitate the introduction of the wire 5 to the thread entry wheel 41, to increase the restriction of the wire 5 below the looper 44, and to increase the pressure of the tension on the looper 44.

When the metal wire 5 is used, when the metal wire 5 is not used up, the wire guiding hole 421, the threading ring 44 and the wire entering wheel 41 are positioned on the same vertical straight line, the metal wire 5 is limited by the wire guiding hole 421 and the wire entering wheel 41, the threading ring 44 is pressed by the tension of the metal wire 5, the threading ring 44 overcomes the elasticity of the elastic piece 45, the wire entering positions of the wire guiding hole 421, the threading ring 44 and the wire entering wheel 41 are positioned on the same straight line, the wire missing sensor 46 senses the rod body 441, and the machine operates normally at the moment; when the metal wire 5 is used up, the wire hole 421 and the metal wire 5 are not abutted, so that the tension of the metal wire 5 cannot be maintained, and the threading ring 44 cannot be pressed, so that the rod body 441 and the threading ring 44 extend out under the action of the elastic member 45, and the thread-missing sensor 46 cannot sense the rod body 441, trigger the alarm module, and inform a worker to timely handle the thread-missing sensor.

As shown in fig. 4 and 5, the wire breakage sensing device 2 includes an installation plate 21 installed at the outlet portion 13 of the molding wire press 1, a strap 22 installed on the installation plate 21, and a wire breakage sensor 23, wherein one end of the strap 22 is rotatably connected to the installation plate 21, the other end thereof is lapped on the metal wire 5, one end of the strap 22 lapped on the metal wire 5 is provided with a slot, and the slot is matched with the metal wire 5 to stably lap on the metal wire 5. The broken line sensor 23 is arranged on the mounting plate 21 and right below the rotating connection position of the lap piece 22 to detect whether the lap piece 22 swings downwards or not, and is electrically connected with the alarm module, when the metal wire 5 is broken, the lap piece 22 swings downwards and is detected by the broken line sensor 23, and when the broken line sensor 23 detects the lap piece 22, the alarm module is triggered to remind a worker.

The side of the mounting plate 21 where the disconnection sensor 23 is mounted is provided with a buffer assembly 24, and the buffer assembly 24 is mainly used for buffering the impact of the fastener 22 on the machine when the fastener 22 swings downwards. The buffer assembly 24 includes a buffer stop fixed at the lower end of the mounting plate 21, and the buffer stop may be made of a rubber pad and metal, and the rubber pad may absorb the impact force caused by the downward swinging of the support member 22 well, so that the impact force may reduce the influence on the service life of the integral forming wire pressing machine 1.

The mounting plate 21 can be additionally provided with a speed reducing assembly 25, and the speed reducing assembly 25 is mainly used for reducing the speed of the lap 22 during downward swinging, so that the normal use of the forming line pressing machine 1 is further ensured. The speed reducing component 25 comprises a first gear 251 and a second gear 252, wherein the first gear 251 is coaxially arranged at the hinged position of the connecting rod 221 on the mounting plate 21, the second gear 252 is meshed with the first gear 251 and is rotatably connected to the mounting plate 21, the first gear 251 and the second gear 252 are both arranged on the back of the mounting plate 21, the speed reducing component 25 is arranged on the second gear 252, the speed reducing component 25 is a screw 253 and a nut 254 which are coaxially arranged with the second gear 252, and the rotating nut 254 tightly abuts against the second gear 252 and the mounting plate 21 to limit the rotating speed of the second gear 252. The reduction assembly 25 is not disposed on the rotation axis of the first gear 251 because the tightening force given by the nut 254 is not easy to control, and is easily too large, which makes the pull rod 221 difficult to rotate, or too small, so that the reduction effect is not obvious. The second gear 252 is disposed on the second gear 252, and since the second gear 252 itself is not driven by the same rotation as the engaging member 22, the tightening force can be better grasped during adjustment. Therefore, when the fastener 22 swings downwards, the friction force between the gears and the rotating shaft can be utilized to reduce the speed through the meshing transmission, and meanwhile, the nut 254 can abut against the second gear 252 to limit the rotation of the second gear 252, so that a good speed reduction effect is achieved.

In a specific operation, under a normal condition, the lap 22 of the disconnection sensing device 2 is lapped on the metal wire 5, and the lap 22 is supported by the tension of the metal wire 5 so as not to swing down due to the action of gravity. When the metal wire 5 is broken, the metal wire 5 at the position cannot support the gravity of the lapping piece 22 due to the breakage, the lapping piece 22 swings downwards under the action of the gravity to shield the wire breakage sensor 23, and the wire breakage sensor 23 senses the lapping piece 22 at the moment, so that the alarm module is triggered to inform a worker, the work of the forming wire pressing machine 1 is stopped, and the wire breakage is processed.
