[0002] During the processing of the bar, a feeder is required to feed and transport the bar so that the bar is automatically fed and transported to the processing position. A general feeder includes a frame, on which a feed trough and a push rod are provided. The push rod and the bar are placed in the feed trough, and the push rod and the bar are located in the same straight line. The push rod is pushed to move along the length direction of the feed trough to push the bar to the processing position. At the same time, a sleeve is fixedly provided at one end of the push rod facing the bar to cover the tail of the bar, so as to improve the stability of the bar processing.

[0003] When the bar processing is completed, the bar tail remains in the sleeve. The bar tail needs to be manually pulled out of the sleeve before the next bar can be transported and processed. Manual pulling is not easy to operate and reduces the processing efficiency of the bar. This problem needs to be solved urgently. Utility Model Content

[0004] In order to facilitate the pulling operation of the rod tail material and to improve the processing efficiency of the rod material, the present application provides a pushing and pulling device.

[0005] The present application provides a material pushing and pulling device, which adopts the following technical solution:

[0006] A material pushing and pulling device is used to be arranged on the frame of a feeder, including a pushing mechanism and a pulling mechanism. The pushing mechanism is arranged on the frame to drive the pushing rod to move along the length direction of the feeding trough, and the pulling mechanism is arranged on the frame to pull the tail of the bar out of the sleeve. The pulling mechanism includes a clamping assembly and a driving assembly. When the bar processing is completed, the clamping assembly is arranged on the frame to clamp and fix the tail of the bar, and the driving assembly is arranged on the frame to drive the sleeve to move in the direction away from the tail of the bar.

[0007] By adopting the above technical solution, when the bar needs to be processed, the pushing mechanism pushes the bar to the processing position through the pushing rod for processing operation. When the bar processing is completed, the bar tail remains in the sleeve. At this time, the clamping assembly clamps and fixes the bar tail, and then the driving assembly drives the sleeve to move away from the bar tail to separate the bar tail and the sleeve, thereby realizing the pulling operation. There is no need for manual pulling, the degree of automation is high, simple and convenient, which is conducive to improving the processing efficiency of the bar.

[0008] Preferably, the pushing mechanism includes a sprocket, a chain, a connecting plate and a first driving member, the number of the sprockets is set to two, the two sprockets are rotatably connected to the two ends of the frame respectively, the chain is meshed around the two sprockets, the connecting plate is fixedly connected to the chain, and the connecting plate is fixedly connected to the pushing rod, and the first driving member is installed on the frame to drive one of the sprockets to rotate.

[0009] By adopting the above technical solution, the first driving member drives a sprocket to rotate, so that the two sprockets drive the chains that are meshed with them to transmit information, and the chain transmission drives the connecting plate to move along the length direction of the feed trough, and the connecting plate then drives the pushing rod to move along the length direction of the feed trough, thereby realizing the pushing operation of the bar.

[0010] Preferably, the driving assembly includes a hook plate, a linkage plate and a second driving member, the hook plate includes a rotating part and a hooking part that are fixedly connected, the rotating part is horizontally rotatably connected to the linkage plate, the second driving member is arranged on the frame to drive the linkage plate to slide back and forth along the length direction of the feed trough, the side wall of the connecting plate is provided with a slot for the hooking part to be inserted, and the driving assembly also includes a magnetic member for causing the hooking part to have a tendency to move toward the connecting plate.

[0011] By adopting the above technical scheme, when the clamping assembly clamps the rod tail, the second driving member drives the linkage plate to move in the direction away from the rod tail, and the linkage plate drives the hook plate to move synchronously in the direction away from the rod tail. During the movement of the hook plate, the magnetic member makes the hooking portion always abut against the side wall of the connecting plate, and as the hooking portion moves, it is inserted into the slot provided in the connecting plate. Through the snap-fit ​​cooperation between the hooking portion and the slot, the hook plate can drive the connecting plate to move in the direction away from the rod tail, and the connecting plate then drives the pushing rod and the sleeve to move in the direction away from the rod tail, thereby realizing the pulling out of the rod tail from the sleeve.

The magnetic plate is horizontally fixedly connected to the frame, the magnetic block is connected to the hooking portion, and the magnetic block is abutted and slidably connected to the side wall of the magnetic plate.

[0013] By adopting the above technical solution, the magnetic plate and the magnetic block that are magnetically matched attract each other, so that the hooking part has a tendency to move toward the connecting plate. When the magnetic block slides in the groove, the hooking part is inserted into the slot, and as the magnetic block moves in the groove, the hooking part is inserted into the slot to drive the connecting plate to move away from the tail of the bar to realize the pulling operation.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a material pushing and pulling device, referring to Figure 1 , which is used to be arranged on the frame 2 of the feeder 1, and the frame 2 is provided with a feeding trough 7 and a pushing rod 8, the pushing rod 8 and the bar are placed in the feeding trough 7, and the pushing rod 8 and the bar are located in the same straight line, and the pushing rod 8 is pushed to move along the length direction of the feeding trough 7 to push the bar to the processing position for processing the bar.

[0034] Reference Figure 2 and Figure 3 The material pushing and pulling device includes a pushing mechanism 3 and a pulling mechanism 4. The pushing mechanism 3 is arranged on the frame 2 to drive the pushing rod 8 to move along the length direction of the feeding trough 7 to push the bar to the processing position for processing. The pulling mechanism 4 is arranged on the frame 2 to pull the bar tail out of the sleeve 9. Specifically, the pulling mechanism 4 includes a clamping assembly 41 and a driving assembly 42. After the bar processing is completed, the clamping assembly 41 is arranged on the frame 2 to clamp and fix the bar tail, and the driving assembly 42 is arranged on the frame 2 to drive the sleeve 9 to move in a direction away from the bar tail, so as to separate the bar tail from the sleeve 9. The separation of the bar tail and the sleeve 9 does not require manual operation, has a high degree of automation, is simple and convenient, and is conducive to improving the processing efficiency of the bar.

[0035] Reference Figure 2The push mechanism 3 includes a sprocket 31, a chain 32, a connecting plate 33 and a first driving member 34. The number of the sprockets 31 is set to two. The two sprockets 31 are respectively rotatably connected to the two ends of the frame 2. The chain 32 is meshed around the two sprockets 31. One end of the connecting plate 33 is fixedly connected to the chain 32, and the other end of the connecting plate 33 is fixedly connected to the push rod 8. The first driving member 34 is installed on the frame 2 to drive one sprocket 31 to rotate. The first driving member 34 drives one sprocket 31 to rotate. Through the meshing cooperation of the two sprockets 31 and the chain 32, the connecting plate 33 can be driven to move along the length direction of the feeding trough 7, and the connecting plate 33 drives the push rod 8 to move along the length direction of the feeding trough 7. In this embodiment, the first driving member 34 includes a driving motor 341 and a reduction wheel group 342. The driving motor 341 is horizontally fixedly connected to the frame 2. The driving motor 341 drives one sprocket 31 to rotate through the reduction wheel group 342 to complete the pushing operation. It should be noted that the drive motor 341 is a servo motor that can be rotated forward and reverse to drive the push rod 8 to move back and forth in the feeding trough 7, and the driving force of the drive motor 341 is relatively gentle, which is beneficial to improving the stability of the push rod 8 during the pushing operation.

[0036] Reference Figure 2 and Figure 3 The clamping assembly 41 includes an upper clamp 411 and a lower clamp 412 that move toward or away from each other. When the bar needs to be processed, the upper clamp 411 and the lower clamp 412 move away from each other to avoid the movement of the bar. When the processing operation of the bar is completed, the upper clamp 411 and the lower clamp 412 move toward each other to clamp the tail of the bar, thereby facilitating the driving assembly 42 to perform the material pulling operation.

[0037] Reference Figure 2 and Figure 4 The driving assembly 42 includes a hook plate 421, a linkage plate 422 and a second driving member. The hook plate 421 includes a rotating portion 4211 and a hooking portion 4212 that are fixedly connected. The linkage plate 422 is horizontally arranged. The rotating portion 4211 is horizontally rotatably connected to the linkage plate 422. The second driving member is arranged on the frame 2 to drive the linkage plate 422 to slide back and forth along the length direction of the feeding trough 7. The side wall of the connecting plate 33 is provided with a slot 5 for the hooking portion 4212 to be inserted. When the hooking portion 4212 is inserted into the slot 5, the movement of the linkage plate 422 can drive the connecting plate 33 to move through the hook plate 421, thereby realizing the separation of the sleeve 9 and the rod tail.

[0038] Reference Figure 2 and Figure 4, the driving assembly 42 also includes a magnetic member 424 for making the hooking portion 4212 have a tendency to move toward the connecting plate 33. Specifically, the magnetic member 424 includes a magnetic plate 4241 and a magnetic block that are magnetically matched. The magnetic plate 4241 is horizontally fixedly connected to the frame 2, and the magnetic block is connected to the hooking portion 4212. The magnetic block is slidably connected to the side wall of the magnetic plate 4241, and the side wall of the magnetic plate 4241 is provided with a groove 6. When the magnetic block moves on the side wall of the magnetic plate 4241, due to the setting of the groove 6, the hooking portion 4212 can be inserted into or out of the slot 5. When the magnetic block slides in the groove 6, the hooking portion 4212 is inserted into the slot 5, and when the magnetic block slides outside the groove 6, the hooking portion 4212 passes through the slot 5. In this embodiment, the magnetic block is configured as a magnetic ring 4242, which is horizontally rotatably connected to the lower end of the hooking portion 4212, and the annular surface of the magnetic ring 4242 is rollingly connected to the side wall of the magnetic plate 4241. In addition, the groove walls at both ends of the groove 6 are chamfered to reduce the friction between the magnetic ring 4242 and the magnetic plate 4241, thereby facilitating the smoothness of the magnetic ring 4242 moving on the magnetic plate 4241.

[0039] When the material extraction operation is required, the clamping assembly 41 clamps and fixes the bar tail, and then the second driving member drives the linkage plate 422 to move in the direction away from the bar tail, and the linkage plate 422 synchronously drives the hook plate 421 to move in the direction away from the bar tail. At this time, the magnetic ring 4242 falls into the groove 6 of the magnetic plate 4241, and the hook holding part 4212 is inserted into the slot 5. As the linkage plate 422 continues to move, the hook holding part 4212 drives the connecting plate 33 to move in the direction away from the bar tail by inserting into the slot 5, thereby realizing the extraction of the bar tail from the sleeve 9. After the bar tail is extracted, the magnetic ring 4242 slides out of the groove 6 of the magnetic plate 4241, so that the hook holding part 4212 passes through the slot 5.

[0040] Reference Figure 3 and Figure 4 The second driving member is configured as a driving cylinder 423, which is horizontally fixed to the frame 2. The piston rod of the driving cylinder 423 is fixedly connected to the linkage plate 422. The stretching or contraction of the piston rod of the driving cylinder 423 drives the linkage plate 422 to move back and forth, so that the hooking portion 4212 of the hook plate 421 drives the sleeve 9 to move toward or away from the clamped and fixed tail of the bar through the slot 5 of the connecting plate 33, and the kinetic energy impact force of the driving cylinder 423 is relatively large, which is convenient for the material pulling operation.

[0041] The implementation principle of a material pushing and pulling device in an embodiment of the present application is as follows: when a pulling operation is required, the upper chuck 411 and the lower chuck 412 move in a direction approaching each other to clamp the tail of the bar, and then drive the piston rod of the cylinder 423 to stretch to drive the linkage plate 422 to move in a direction away from the tail of the bar, and the linkage plate 422 synchronously drives the hook plate 421 to move in a direction away from the tail of the bar. At this time, the magnetic ring 4242 falls into the groove 6 of the magnetic plate 4241, and the hooking portion 4212 is inserted into the slot 5. As the linkage plate 422 continues to move, the hooking portion 4212 drives the connecting plate 33 to move in a direction away from the tail of the bar by being inserted into the slot 5, thereby realizing the pulling out of the tail of the bar from the sleeve 9. There is no need for manual pulling, the degree of automation is high, and it is simple and convenient, which is conducive to improving the processing efficiency of the bar.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
