[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-8 As shown, the present invention proposes an automatic feeding device for steel bar sawing, threading, and cage welding numerical control equipment, comprising a transmission component 1, a sawing component 2, a base plate 3, and a vibration component 4. A storage rack 302 is fixedly installed on the top of the base plate 3 near the front position. The base plate 3 can provide a mounting position for the components on the top. The storage rack 302 is an inclined frame structure that can store the steel bars that have been cut and sawed, thereby facilitating the later retrieval of the steel bars one by one when producing the steel cage. A saw assembly 2 is fixedly mounted on the back of the storage rack 302. The saw assembly 2 can align the steel bars so that they are cut into the same length, thereby making the length of the steel cage produced uniform. This adds a pre-processing and cutting function to the steel bars during the process of transporting the steel bars. The transmission assembly 1 is fixedly mounted on the back of the saw assembly 2. The transmission assembly 1 can translate the steel bars between the saw assembly 2 and the vibration assembly 4, thereby replacing the traditional manual batch transfer of steel bars, improving the efficiency of steel bar transportation and greatly saving manpower. A vibration component 4 is fixedly mounted on the back of the transmission component 1. The vibration component 4 can generate high-frequency vibrations and drive the steel bars to vibrate synchronously, so as to shake the steel bars apart and lay them flat, making it easier for the subsequent transportation and sawing of the steel bars. A discharge rack assembly 5 is fixedly installed on the back of the vibration assembly 4. The discharge rack assembly 5 can place unprocessed steel bars and can transport a certain number of steel bars according to actual needs, so that the steel bars are moved to the top of the vibration assembly 4 for vibration processing.

A tensioning wheel 101 is rotatably installed on the inner side of the shaft frame 102, and the tensioning wheel 101 It is connected to the transmission chain 109, and the slide 103 is driven and limited respectively by the lead screw 106 and the limit rod 108 inside the transmission component 1. After the lead screw motor 107 is energized, it rotates to drive the lead screw 106 to rotate, so that the thread on the outside of the lead screw 106 matches the internal thread of the slide 103, and then the slide 103 drives the top component to move horizontally, thereby adjusting the horizontal position of the transmission chain 109. The transmission chain 109 is driven by power and rotation of the drive motor 105. While the transmission chain 109 rotates, it supports the steel bars and drives the steel bars to move horizontally at the top of the transmission chain 109, which can enable the steel bars to be transferred between the vibration component 4 and the cutting saw component 2 through the transmission component 1, thereby greatly saving the cost of manual transfer and improving the efficiency of transfer.

[0022] Furthermore, the saw assembly 2 includes a mounting shell 204, a plurality of guide plates 206 are mounted on the top of the mounting shell 204, and a plurality of grooves are formed on the top of the guide plates 206.

When the steel bars are in contact with the sliding frame 202 and the cutting length is adjusted, the steel bars are cut by the cutting machine 207 so that the steel bars are cut into the same length and moved to the top of the storage rack 302 under the push of the material taking rack 201 for placement, so as to facilitate the subsequent use of the steel bars.

[0023] Furthermore, the vibration assembly 4 includes a vibration table 407, two spring columns 402 are fixedly installed on both sides of the bottom of the vibration table 407, side baffles 406 are fixedly installed on the left and right sides of the top of the vibration table 407, and vibration motors 405 are fixedly installed on both sides of the bottom of the vibration table 407.

Several electromagnets are fixedly installed at the bottom, and the interior of the support frame 404 is filled with magnetic fluid, the filling amount of which is 70% to 90% of the volume of the support frame 404. The vibration motor 405 drives the vibration table 407 and the components on its top to vibrate at high frequency, so that the steel bars fallen on the top of the vibration table 407 are shaken off, and the electromagnet applies magnetic force to the magnetic fluid inside the support frame 404, so that the magnetic fluid applies thrust to the mask 401, thereby forming an upwardly convex arc surface of the mask 401, assisting the vibration table 407 to lay the steel bars flat, thereby facilitating the subsequent use of the steel bars one by one, and avoiding the cross-stacked steel bars affecting the transportation and cutting of the steel bars.

[0024] Furthermore, the unloading rack assembly 5 includes a material storage table 502, a main shaft 505 is rotatably installed on the top of the material storage table 502 near the front position, a first motor 503 is installed on one end of the main shaft 505, and the first motor 503 is fixedly connected to the material storage table 502, a material unloading shaft 507 is installed on the top of the material storage table 502 in front of the main shaft 505, and a plurality of guide hooks 506 are installed at equal intervals on the outside of the material unloading shaft 507, a second motor 504 is installed on one end of the material unloading shaft 507, and the second motor 504 is fixedly connected to the material storage table 502, an auxiliary shaft 501 is rotatably installed on the top of the material storage table 502 near the back position, and the auxiliary shaft 501 and the main shaft 505 are connected. There are several conveyor belts 508 on the outside, and the first motor 503 and the second motor 504 are both YE4-100KW type. The storage table 502 and the components on its top can support the steel bars and are used to place the steel bars. When the steel bars need to be taken, the main shaft 505 and the auxiliary shaft 501 drive the conveyor belt 508 to roll, and the steel bars are moved to a position close to the discharge shaft 507. The discharge shaft 507 drives several guide hooks 506 to rotate at the same time, and the steel bars on the top of the conveyor belt 508 are taken out one by one and moved to the top of the vibration component 4, thereby replacing manual labor to take the steel bars, and being able to control the quantity of steel bars taken, saving the manpower required for taking the steel bars.

[0025] Furthermore, a control cabinet 301 is fixedly installed on one side of the top of the base plate 3, and the control cabinet 301 is connected to the transmission component 1, the cutting and sawing component 2, the vibration component 4 and the material rack component 5 through cables. The external power supply of the control cabinet 301 is used to power and control the electronic components inside the device through cables, so that multiple components inside the device can cooperate with each other to automatically transmit, transfer and cut the steel bars, thereby realizing automatic feeding.

[0026] Furthermore, a push plate is fixedly installed on the front of the sliding frame 202, and a distance of one to five centimeters is set between the bottom surface of the push plate and the top surface of the guide plate 206. The push plate can move horizontally synchronously with the sliding frame 202, thereby aligning the steel bars, making it convenient for the subsequent cutting machine 207 to cut multiple steel bars into steel bars of the same length.

[0027] Furthermore, the material picking rack 201 is arranged between two adjacent guide plates 206, and the installation position of the material picking rack 201 is lower than the guide plate 206. The material picking rack 201 can be flipped with the driving shaft 205 as the center of the circle, and then can support the steel bars on the top of the guide plate 206 from the bottom, and move the steel bars after cutting to the storage rack 302.

After the servo motor is energized, it can drive the drive shaft 205 to rotate, and then the drive shaft 205 drives several material racks 201 to flip over, thereby transporting the steel bars on the top of the guide plate 206.

[0029] Working principle: After the device is checked and confirmed to be correct, the device is numerically controlled through the control cabinet 301, and several steel bars are placed on the conveyor belt 508 on the top of the storage table 502. The first motor 503 drives the main shaft 505 to rotate, so that the conveyor belt 508 rolls and drives the top steel bars to move horizontally toward the vibration component 4. At the same time, the second motor 504 is powered on and rotates to drive the discharge shaft 507 to rotate back and forth, so that the discharge shaft 507 drives the guide hook 506 to rotate back and forth, and the steel bars on the top of the conveyor belt 508 are placed on the conveyor belt 508. The steel bars are transported one by one to the top of the vibration assembly 4. After the specified number of steel bars are taken, the unloading rack assembly 5 stops operating, and the vibration motor 405 is powered on to drive the vibration table 407 and the components on its top to vibrate at high frequency, so that the steel bars are shaken off on the top of the vibration table 407. At the same time, the electromagnet exerts a magnetic force on the magnetic fluid inside the support frame 404, so that the magnetic fluid pushes the mask 401 to form an arc surface, promoting the flattening of the steel bars on the top of the support frame 404. After the flattening of the steel bars is completed, the lifting cylinder 403 is used to lift the flattened steel bars. The screw motor 107 drives the screw rod 106 to rotate, so that the chute 103 drives the top component to move to the bottom of the steel bar, and the lifting cylinder 403 slowly contracts to place the steel bar on the top of several transmission chains 109. The screw motor 107 drives the screw rod 106 to rotate in the opposite direction, so that the chute 103 drives the top component and the steel bar to move toward the cutting saw component 2. At the same time, the driving motor 105 drives the transmission chain 109 to roll, and the steel bars are placed one by one on the top of the guide plate 206. The electromagnetic guide rail 203 drives the The sliding frame 202 and the push plate move horizontally, so that the several steel bars that fall on the top of the guide plate 206 move toward the cutting machine 207, and the push plate contacts one end of the several steel bars to align the steel bars. After the steel bars are cut by the cutting machine 207, the steel bars are processed into a uniform length, and then the driving shaft 205 drives the material taking frame 201 to flip over, and the processed steel bars are uniformly placed on the top of the storage rack 302, so that after the steel bars are processed inside the device, the automatic feeding of the steel cage CNC processing equipment is completed.
