Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, specifically a device for screw processing. Background Technology

[0002] A thread rolling machine is a metal processing device used to process threads, knurling, or other surface shapes. It applies pressure to the workpiece through rotating rolling rollers to form the desired shape on the workpiece surface. Thread rolling machines are widely used in the manufacture of parts such as screws, bolts, lead screws, and pipe fittings.

[0003] According to the utility model patent application CN211965771U, a thread rolling machine is disclosed. This equipment drives a lifting rod to rotate via a drive assembly, thereby causing the mounting block to move vertically and thus raising and lowering the rollers to accommodate workpieces of different sizes. The rollers limit the upper part of the workpiece, and the arc-shaped groove helps to confine the workpiece within the feeding trough, reducing friction and wear. However, during operation, the forming rollers are subjected to significant pressure, leading to severe wear. The long replacement interval of the forming rollers reduces screw production output. Therefore, we provide a device for screw processing to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a device for screw processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for screw processing, comprising a base plate, wherein a replacement mechanism is provided above the base plate;

[0006] The replacement mechanism includes two first fixed plates. Two first rotating shafts are rotatably connected to the inner wall of each first fixed plate. A stepper motor is located behind each first fixed plate. Two second fixed plates are fixedly connected to the upper surface of the base plate. A long shaft is rotatably connected to the inner wall of each second fixed plate and the inner wall of each first fixed plate. A first rotating plate and a second rotating plate are fixedly connected to the outer surface of each long shaft. Two rotating shafts are rotatably connected to the inner wall of each first rotating plate. A forming roller is engaged on the outer surface of each rotating shaft. Two slots are formed on the front of each second rotating plate. A locking block is engaged inside each slot. A disassembly plate is fixedly connected to the end of each locking block away from the stepper motor. A second rotating shaft is rotatably connected to the inner wall of each disassembly plate. A baffle is engaged inside each second fixed plate. A third rotating shaft is rotatably connected to the inner wall of each baffle and the inner wall of each second fixed plate. A cross plate is engaged inside each of the first, second, third, and rotating shafts.

[0007] Furthermore, each stepper motor has a support base fixedly connected to its bottom surface, and the front of each support base is fixedly connected to the back of the base plate.

[0008] Furthermore, a guide block is fixedly connected to the back of the base plate, and the bottom surface of each of the first fixing plates is fixedly connected to the upper surface of the base plate.

[0009] Furthermore, each of the baffles has a bolt threadedly connected to its inner wall, and the outer surface of each bolt is threadedly connected to the inner wall of the base plate.

[0010] Furthermore, a turntable is fixedly connected to the end of each of the long shafts away from the baffle, and a rotating handle is fixedly connected to the back of each of the turntables.

[0011] Furthermore, a pull handle is fixedly connected to the front of each of the cross plates, the output ends of the two first stepper motors are fixedly connected to the ends of the two first rotating shafts near the stepper motors, and the front of each of the disassembly plates is in contact with the back of the baffle.

[0012] Compared with existing technologies, this device for screw processing has the following advantages:

[0013] This invention features a cross plate. By removing the cross plate, the transmission relationship between the first, second, and third rotating shafts and the rotating shaft can be broken. At this time, the power generated by the stepper motor will only act on the first rotating shaft and cannot be transmitted to the rotating shaft and forming roller through the cross plate. Furthermore, due to the absence of the cross plate's restraint, the long shaft can rotate freely. This allows the long shaft to be rotated, driving the first and second rotating plates to rotate 180 degrees, thus exchanging the positions of the two forming rollers and completing the replacement of the forming rollers. This significantly reduces standby time and avoids the problem of reduced screw output. Attached Figure Description

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] This embodiment provides a device for screw processing, which is used to process screws and facilitates the replacement of worn forming rollers during processing.

[0022] See Figure 1 and Figure 5 A device for screw processing includes a base plate 1. A replacement mechanism 2 is arranged above the base plate 1. The replacement mechanism 2 includes two first fixed plates 201. Two first rotating shafts 210 are rotatably connected to the inner wall of each first fixed plate 201. A stepper motor 202 is arranged behind each first fixed plate 201. A support seat 5 is fixedly connected to the bottom surface of each stepper motor 202. The front of each support seat 5 is fixedly connected to the back of the base plate 1. By providing the support seat 5, the stability of the device can be increased, making the device operate more stably.

[0023] See Figure 1 , Figure 3 and Figure 5 Two second fixing plates 206 are fixedly connected to the upper surface of the base plate 1. The inner wall of each second fixing plate 206 and the inner wall of the first fixing plate 201 are rotatably connected to a long shaft 203. The outer surface of each long shaft 203 is fixedly connected to a first rotating plate 215 and a second rotating plate 209. The inner wall of each first rotating plate 215 is rotatably connected to two rotating shafts 214. A guide block 8 is fixedly connected to the back of the base plate 1. The bottom surface of each first fixing plate 201 is fixedly connected to the upper surface of the base plate 1. By setting the guide block 8, the formed screw can be guided to move backward.

[0024] See Figures 1-4Each rotating shaft 214 has a forming roller 204 attached to its outer surface. Each second rotating plate 209 has two slots 216 on its front side. Each slot 216 has a locking block 207 attached inside. Each locking block 207 has a disassembly plate 211 fixedly connected to its end away from the stepper motor 202. Each disassembly plate 211 has a second rotating shaft 212 rotatably connected to its inner wall. Each second fixed plate 206 has a baffle 205 attached inside. Each baffle 205 has a bolt 3 threadedly connected to its inner wall. The outer surface of each bolt 3 is threadedly connected to the inner wall of the base plate 1. By setting the bolts 3, the baffle 205 can be fixed on the base plate 1, making the baffle 205 more stable.

[0025] See Figure 2 and Figure 5 Each baffle 205 and the inner wall of the second fixed plate 206 are rotatably connected to a third rotating shaft 208. Each long shaft 203 is fixedly connected to a turntable 6 at the end away from the baffle 205. Each turntable 6 is fixedly connected to a rotating handle 7 on its back. By providing the rotating handle 7, the rotating power of the turntable 6 can be easily applied.

[0026] See Figure 1 and Figure 2 Each of the first rotating shaft 210, the second rotating shaft 212, the third rotating shaft 208, and the rotating shaft 214 has a cross plate 213 inside. Each cross plate 213 has a pull handle 4 fixedly connected to its front side. The output ends of the two first stepper motors 202 are fixedly connected to the ends of the two first rotating shafts 210 near the stepper motors 202. The front side of each disassembly plate 211 is in contact with the back side of the baffle 205. By providing the pull handle 4, the cross plate 213 can be easily pulled out, which has a good auxiliary effect.

[0027] Working principle: During use, the stepper motor 202 can be controlled to run, which drives the first rotating shaft 210 to rotate. A cross plate 213 is internally engaged with the first rotating shaft 210, and the surface of the cross plate 213 is also engaged with the second rotating shaft 212, the third rotating shaft 208, and the rotating shaft 214. Therefore, the stepper motor 202 drives the forming roller 204, which is engaged with the surface of the rotating shaft 214, to rotate. When raw materials are placed between the two forming rollers 204, the forming rollers 204 will compress the raw materials and shape them, moving them towards the guide block 8. When the forming roller 204 is severely worn and needs to be replaced, firstly... Disconnect the power supply to the stepper motor 202 to stop its operation. Then, pull the handle 4 to remove the cross plate 213, thus disconnecting the transmission relationship between the first rotating shaft 210, the second rotating shaft 212, the third rotating shaft 208, and the rotating shaft 214. Since the cross plate 213 is no longer limiting the movement, the long shaft 203 can rotate freely. It's important to understand that when the cross plate 213 is engaged inside the first rotating shaft 210 and the rotating shaft 214, part of the cross plate 213 is inside the first rotating shaft 210 and the first fixed plate 201, while another part is inside the first rotating plate 215 and the rotating shaft 214. The rotation of the long shaft 203, however, requires the first rotating shaft 208 to rotate. The rotating plate 215 rotates, so the cross plate 213 can limit the long shaft 203. Thus, by rotating the handle 7 and the turntable 6, rotational power is applied to the long shaft 203. The long shaft 203 drives the first rotating plate 215 and the second rotating plate 209 to rotate 180 degrees, exchanging the positions of the severely worn forming roller 204 and the forming roller 204 to be used, thereby completing the replacement of the forming roller 204. Then, the cross plate 213 connects the internal rotating shaft 214 of the forming roller 204 to the first rotating shaft 210, the second rotating shaft 212, and the third rotating shaft 208, and then the stepper motor 202 can be controlled to run. The screw can then be processed normally. At this time, the severely worn forming roller 204 is still located on the surface of another rotating shaft 214. Then, the bolt 3 can be unscrewed and the baffle 205 can be removed. At this time, there is no obstruction in front of the disassembly plate 211, so the disassembly plate 211, the second rotating shaft 212 and the clamping block 207 can be removed from the second rotating plate 209. When the disassembly plate 211 is removed, the severely worn forming roller 204 can be removed and a new forming roller 204 can be placed and clamped onto the surface of the rotating shaft 214. This can greatly reduce the standby time and avoid the problem of low screw output.
