[0067] Example 1

[0068] like Figure 1-20 As shown, a multi-station automatic rod polishing machine is provided. The outer casing 1 has multiple mounting seats inside, and the mounting seats are at an angle. A polishing machine 11 is mounted on the mounting seats. The head of the frame 1101 of the polishing machine 11 is provided with two clamping grinding wheels. The two clamping grinding wheels are driven by a motor 1103. The tail of the frame 1101 is provided with a clamping cylinder 1102, which drives the two grinding wheels to clamp together.

[0069] The grinding space of the grinding wheels on multiple polishing machines 11 is set on the same axis.

[0070] The core structure of the multi-station automatic wire rod polishing machine lies in the multiple mounting seats inside the outer casing 1. These mounting seats have a certain inclination angle, typically 15-20°, to meet different processing requirements. Each mounting seat is equipped with a polishing machine 11, forming a multi-station layout. The head of the frame 1101 of the polishing machine 11 is equipped with two clamping grinding wheels, driven by a motor 1103 to ensure stable and efficient operation. Simultaneously, the tail of the frame 1101 is equipped with a clamping cylinder 1102, which controls the air pressure to drive the two grinding wheels to achieve clamping action, thereby adjusting the grinding force. Furthermore, the grinding spaces of the grinding wheels on the multiple polishing machines 11 are designed on the same axis, ensuring that the wire can pass smoothly along the same axis during processing, improving processing efficiency and accuracy. This design achieves efficient surface treatment of coiled wires such as titanium steel, stainless steel, and steel, including oxide scale removal and polishing processes, effectively solving the environmental pollution problems caused by traditional pickling processes.

[0071] In the preferred embodiment, the tilt angle between adjacent mounting bases is 15-20°, and a total of 12 polishing machines (11 stations) are set up. These 12 polishing machines (11) are evenly distributed within a semi-circular area, achieving a reasonable layout through equidistant arrangement. This design not only ensures the smooth operation of the wire during processing but also improves the uniformity and efficiency of surface treatment, making it suitable for descaling and polishing processes of coiled wires such as titanium steel, stainless steel, and steel.

[0072] The motor 1103 of the polishing machine 11 is a hollow shaft motor;

[0073] The front end of the motor 1103 is connected to the drive center shaft 1106. The drive center shaft 1106 has multiple axial slots. The drive center shaft 1106 is a hollow shaft. Inside the shaft, there are two second flanges 1111 and a fifth flange 1120. The flange claws of the second flanges 1111 and the fifth flange 1120 pass through the slots and are slidably connected to the drive center shaft 1106. A second grinding wheel 1105 is installed on the flange claw of the second flange 1111, and a first grinding wheel 1104 is installed on the flange claw of the fifth flange 1120.

[0074] The fifth flange 1120 is connected to the first drive rod 1117, and the first drive rod 1117 passes through the motor 1103 and is a hollow shaft that is rotatably connected to the first docking seat 1124;

[0075] The second flange 1111 is connected to the second drive rod 1107, and the second drive rod 1107 passes through the central axis of the first drive rod 1117 and is rotatably connected to the second docking seat 1123.

[0076] The two ends of the clamping cylinder 1102 are connected to the second docking seat 1123 and the first docking seat 1124, respectively.

[0077] The motor 1103 of the polishing machine 11 adopts a hollow shaft motor design, with its front end connected to the drive center shaft 1106. The drive center shaft 1106 is an internally hollow shaft structure with multiple axial slots, facilitating the sliding connection of the flange claws of the second flange 1111 and the fifth flange 1120 through the slots. The second grinding wheel 1105 is mounted on the flange claw of the second flange 1111, while the first grinding wheel 1104 is mounted on the flange claw of the fifth flange 1120.

[0078] The fifth flange 1120 is rotatably connected to the first mating seat 1124 via the first drive rod 1117, which passes through the hollow shaft of the motor 1103 to achieve the connection. At the same time, the second flange 1111 is rotatably connected to the second mating seat 1123 via the second drive rod 1107, which passes through the central axis of the first drive rod 1117 to complete the assembly.

[0079] Furthermore, the two ends of the clamping cylinder 1102 are respectively connected to the second mating seat 1123 and the first mating seat 1124, and are used to drive the first grinding wheel 1104 and the second grinding wheel 1105 to achieve the clamping action. (This is in conjunction with the provisions of this application.) Figures 5 to 9 As shown, the above structure mainly describes the installation method of the first grinding wheel 1104 and the second grinding wheel 1105 and their connection relationship with related components, ensuring that the grinding wheels can operate stably and achieve precise grinding during operation.

[0080] In the preferred embodiment, one side of the second grinding wheel 1105 is fixedly connected to the third flange 1114, and one side of the third flange 1114 is connected to the second flange 1111 by a plurality of first screws 1112. There is a gap between the nut head of the first screw 1112 and the side of the countersunk hole of the third flange 1114.

[0081] The second flange 1111 has a protrusion on its outer ring, and the third flange 1114 has a groove at the corresponding position of the protrusion. A gap is formed between the groove and the protrusion, and an elastic disc spring is provided inside the gap.

[0082] The third flange 1114 leaves a gap between the protrusion and the side wall of the groove, so that the second grinding wheel 1105 can undergo a slight positional change during grinding.

[0083] One side of the second grinding wheel 1105 is fixedly connected to the third flange 1114, while the other side of the third flange 1114 is connected to the second flange 1111 by multiple first screws 1112. A certain gap is reserved between the nut head of the first screw 1112 and the countersunk hole side of the third flange 1114. This design ensures that the connection structure has a certain degree of flexibility.

[0084] Furthermore, the outer ring of the second flange 1111 has a protrusion, while the third flange 1114 has a groove at the corresponding position. The protrusion and groove between the two form a gap, and an elastic disc spring is disposed inside this gap. This design not only enhances the stability of the structure but also allows the second grinding wheel 1105 to undergo slight positional changes during grinding, thereby accommodating minor deviations that may occur during processing.

[0085] like Figure 7 The structure shown further clarifies the gap between the protrusion and the sidewall of the groove in the third flange 1114. This design feature allows the second grinding wheel 1105 to make minute position adjustments during the grinding process according to the actual force conditions, effectively improving the grinding accuracy and adaptability, while reducing the risk of wear or damage that may be caused by rigid contact.

[0086] The second flange 1111 is also provided with a through hole on one side. One end of the through hole is connected to the center hole of the second drive rod 1107, and the other end of the through hole is connected to one end of the bent water spray cooling pipe 1115. The other end of the water spray cooling pipe 1115 faces between the first grinding wheel 1104 and the second grinding wheel 1105. The tail of the second drive rod 1107 is connected to the water supply connector 1109 in a rotating seal. The head of the second drive rod 1107 is provided with a plug.

[0087] The second flange 1111 has a through hole on one side. One end of the through hole communicates with the center hole of the second drive rod 1107, and the other end is connected to one end of the bent water spray cooling pipe 1115. The other end of the water spray cooling pipe 1115 faces the area between the first grinding wheel 1104 and the second grinding wheel 1105, and is used to cool the heat generated during the grinding process. At the same time, the tail of the second drive rod 1107 is connected to the water supply connector 1109 through a rotating seal, ensuring that cooling water can be smoothly input and achieve the circulating cooling function. In addition, the head of the second drive rod 1107 is provided with a plug to prevent cooling water leakage.

[0088] During operation, the water spray cooling pipe 1115 rotates synchronously with the second flange 1111, thereby continuously cooling the area between the first grinding wheel 1104 and the second grinding wheel 1105. This design not only improves cooling efficiency but also effectively extends the service life of the grinding wheels, while ensuring the stability and precision of the grinding process.

[0089] In the preferred embodiment, the second mating seat 1123 is connected to the first flange 1108, the first flange 1108 is rotatably connected to the rotary joint 1110, and the second drive rod 1107 passes through and is connected to the rotary joint 1110.

[0090] The second mating seat 1123 is connected to the first flange 1108, which in turn is connected to the rotary joint 1110 via a rotatable connection. Simultaneously, the second drive rod 1107 passes through and is fixedly connected to the rotary joint 1110. This structural design allows the first flange 1108 to drive the second grinding wheel 1105 to move back and forth when the second mating seat 1123 is moved.

[0091] The precise displacement control of the second grinding wheel 1105 under the drive of the clamping cylinder 1102 is achieved through the rotatable connection between the first flange 1108 and the rotary joint 1110, and the fixed connection between the second drive rod 1107 and the rotary joint 1110. This flexible movement mechanism not only improves the contact between the grinding wheel and the wire surface, but also allows for adjustment of grinding force and position according to processing requirements, thereby improving grinding efficiency and processing accuracy. Furthermore, this structure effectively reduces frictional wear between mechanical parts, extending the service life of the equipment.

[0092] In the preferred embodiment, the first grinding wheel 1104 is fixed on one side of the fourth flange 1116. The fourth flange 1116 and the fifth flange 1120 are connected by a plurality of second screws 1119. A gap is left between the nut head of the second screw 1119 and the countersunk hole side of the fifth flange 1120.

[0093] The outer ring of the fifth flange 1120 is also provided with a raised ring, and the fourth flange 1116 is provided with a groove at the corresponding position of the raised ring. There is a gap between the two sides of the raised ring and the two inner sides of the groove, and a first disc spring 1113 is provided between the end face of the raised ring and the bottom surface of the groove, so that the first grinding wheel 1104 can have a slight positional change during grinding and return to its original position under the support of the first disc spring 1113.

[0094] The first grinding wheel 1104 is fixedly installed via the fourth flange 1116, and the fourth flange 1116 is connected to the fifth flange 1120 by multiple second bolts 1119. A certain gap is reserved between the nut head of the second bolt 1119 and the countersunk hole side of the fifth flange 1120. This design provides a small amount of room for movement in the structure, enhancing its flexibility.

[0095] Furthermore, the outer ring of the fifth flange 1120 is provided with a raised ring, while the fourth flange 1116 has a groove at the corresponding position. A gap is left between the two sides of the raised ring and the two inner sides of the groove, and a first disc spring 1113 is disposed between the end face of the raised ring and the bottom surface of the groove. This structural design allows the first grinding wheel 1104 to undergo slight positional changes during grinding according to the force applied, and automatically return to its original position under the support of the first disc spring 1113, thereby effectively adapting to minor deviations during processing and improving grinding accuracy and stability.

[0096] like Figure 9The structure shown further clarifies the above design features, ensuring that the first grinding wheel 1104 can maintain good fit during operation, while avoiding excessive wear or damage caused by rigid contact, thus extending the service life of the grinding wheel.

[0097] The tail of the first drive rod 1117 is fixedly connected to the sixth flange 1121, the sixth flange 1121 is rotatably connected to the seventh flange 1122, and the seventh flange 1122 is connected to the first mating seat 1124.

[0098] The tail of the first drive rod 1117 is fixedly connected to the sixth flange 1121, while the sixth flange 1121 and the seventh flange 1122 are connected by a rotatable connection, and the seventh flange 1122 is further connected to the first docking seat 1124. This structural design allows the sixth flange 1121 and the seventh flange 1122 to rotate flexibly during lateral movement when the first docking seat 1124 moves.

[0099] This design, through a rotating connection between flanges, effectively reduces frictional resistance between components while ensuring precise positioning of the first grinding wheel 1104 and the second grinding wheel 1105 under the drive of the clamping cylinder 1102. This flexible movement mechanism not only improves the adaptability of the equipment but also ensures good contact between the grinding wheels and the wire surface during grinding, thereby improving processing accuracy and efficiency. Furthermore, this structure effectively distributes stress, reduces component wear, and extends the service life of the equipment.

[0100] In the preferred embodiment, a sealing plate 1125 is provided at the end of the drive center shaft 1106. The sealing plate 1125 is fixed to the end of the drive center shaft 1106 by a plurality of long screws, and the slot opening on the drive center shaft 1106 extends all the way to the end.

[0101] A drive protective cover 1127 is sleeved at the connection position between the output shaft of the motor 1103 and the drive center shaft 1106. The open end face of the drive protective cover 1127 is close to the motor 1103 body. The closed end of the drive protective cover 1127 is fixedly connected to the drive center shaft 1106. A fixed guide ring 1129 is provided inside the drive protective cover 1127. There is a gap between the outside of the fixed guide ring 1129 and the inner side of the drive protective cover 1127. One end of the fixed guide ring 1129 is fixed on the motor 1103 body. The inner side of the fixed guide ring 1129 is slidably connected to the outer surface of the drive center shaft 1106.

[0102] One end of the drive center shaft 1106 passes through the center shaft hole of the motor 1103 and is connected to the center shaft at the tail of the motor 1103 by a spline snap-fit.

[0103] A sealing plate 1125 is fixed to the end of the drive shaft 1106 by multiple long screws, serving a sealing function. The slotted opening on the plate extends to the end, providing space for the installation and sliding of internal components. A drive protective cover 1127 is fitted at the connection point between the drive shaft 1106 and the motor 1103. The open end of the protective cover is close to the motor 1103 body, while the closed end is fixed to the drive shaft 1106.

Then, the drying chamber 14 starts to dry the surface of the round wire. After drying, the electromagnet inside the iron removal device 10 adsorbs the excess iron core on the surface of the round wire, thus completing the surface descaling and polishing treatment of the round wire.
