Description

Technical Field

[0001] This application relates to the technical field of automated equipment, and in particular to a copper tube terminal processing equipment. Background Art

[0002] A copper tube terminal is an electronic component used for connecting circuits in industrial equipment and vehicles such as automobiles.

[0003] Referring to Figure 1 , two through grooves are opened on the side wall of the copper tube terminal, and the side wall of the copper tube terminal between the two through grooves is recessed towards the inside of the copper tube terminal. The wire can be inserted into the copper tube terminal from both ends, and then tin liquid is dripped into the copper tube terminal through the through grooves to fix the wire to the copper tube terminal. The opening of the two through grooves facilitates the dripping of the tin liquid, making the fixation between the wire and the copper tube terminal more convenient and reliable.

[0004] However, there is no equipment on the market that can be used for the production of the above copper tube terminals. The purpose of this application is to provide a processing equipment that can be used for processing and producing the above copper tube terminals. Summary of the Invention

[0005] In order to solve the problem of processing and producing the above copper tube terminals, the purpose of this application is to provide a copper tube terminal processing equipment.

[0006] A copper tube terminal processing equipment provided by this application adopts the following technical solutions: A copper tube terminal processing equipment includes a machine table, an outlet is opened on the machine table, and the machine table is provided with a feeding mechanism, a material fixing mechanism for fixing the copper tube terminal, a clamping mechanism that cooperates with the feeding mechanism and the material fixing mechanism, a pushing mechanism for pushing the copper tube terminal into the clamping mechanism, a blanking mechanism for controlling the movement of the clamping mechanism, a cutting mechanism for cutting the copper tube terminal, a pressing mechanism for stamping on the copper tube terminal, a ejecting mechanism for ejecting the copper tube terminal out of the clamping mechanism, and a limiting mechanism for limiting the copper tube terminal.

[0007] By adopting the above technical solution, when it is necessary to process the copper tube terminal, the feeding mechanism needs to be started first to realize the feeding of the copper tube terminal. When the solid material mechanism no longer limits the copper tube terminal, the copper tube terminal can fall. The solid material mechanism can ensure that only one copper tube terminal falls each time. After the feeding of the copper tube terminal is completed, the pushing mechanism will push the copper tube terminal into the clamping mechanism. At this time, the cutting mechanism is started, and the blanking mechanism moves toward the side close to the cutting mechanism, driving the clamping mechanism to move toward the side close to the cutting mechanism. The cutting mechanism can then make openings on the side wall of the copper tube terminal, cutting out two through grooves. After the work of cutting out two through grooves on the side wall of the copper tube terminal is completed, the ejecting mechanism is started. The ejecting mechanism moves toward the side close to the copper tube terminal and passes through the copper tube terminal to remove the burrs on the inner wall of the copper tube terminal. Then the pressing mechanism is started. The pressing mechanism moves toward the side close to the copper tube terminal and pushes the side wall of the copper tube terminal between the two through grooves toward the inside of the copper tube terminal, causing the side wall of the copper tube terminal between the two through grooves to be recessed into the copper tube terminal. Then the clamping mechanism releases the copper tube terminal, and the ejecting mechanism is started again to eject the copper tube terminal placed in the clamping mechanism out of the clamping mechanism. The copper tube terminal moving with the ejecting mechanism will enter the limiting mechanism and be limited. When the ejecting mechanism retracts, due to the limitation of the limiting mechanism, the copper tube terminal will not retract with the retraction of the ejecting mechanism, and the copper tube terminal will freely fall to the discharge port, thus completing the processing of the copper tube terminal once.

[0008] Optionally, the feeding mechanism includes a vibrating bowl, a feeding pipe connected to the vibrating bowl, and an inclined feeding column connected to the feeding pipe. The feeding column is provided with a feeding groove adapted to the copper tube terminal, and the feeding groove is communicated with the feeding pipe. The feeding mechanism further includes a feeding table, and one end of the feeding column away from the feeding pipe abuts against the feeding table.

[0009] By adopting the above technical solution, the copper tube terminals are placed in the vibrating bowl. The vibrating bowl vibrates, causing the copper tube terminals to enter the feeding pipe in sequence. The copper tube terminals entering the feeding pipe will enter the feeding groove in sequence. Since one end of the feeding column away from the feeding pipe abuts against the feeding table and the feeding column is inclined, the copper tube terminals will slide into the feeding table under the action of gravity, and then the pushing mechanism can push the copper tube terminals.

[0010] Optionally, the solid material mechanism includes an electromagnetic member. A first connecting block is connected to the electromagnetic member. A connecting rod and a first inserting rod are connected to the first connecting block. The first inserting rod penetrates through the feeding column and extends into the feeding groove. A connecting disk is connected to the connecting rod. The connecting disk is arranged on the side of the feeding column away from the electromagnetic member and abuts against the feeding column. A second connecting block is connected to one end of the connecting rod away from the electromagnetic member. A reset member is arranged between the connecting disk and the second connecting block. A second inserting rod is connected to the second connecting block. The second inserting rod penetrates through the feeding column and extends into the feeding groove.

[0011] By adopting the above technical solution, the first plug rod and the second plug rod can play a role in fixing the copper tube terminal. When the electromagnetic component is in the energized state, the electromagnetic component adsorbs the first connecting block and moves it towards the side close to the electromagnetic component, driving the connecting rod and the first plug rod to move towards the side close to the electromagnetic component, and the reset component is pushed. At this time, the first plug rod does not extend into the feeding groove, and the copper tube terminal located on the side close to the feeding table and in contact with the first plug rod can fall. At this time, the second plug rod will extend into the feeding groove and contact the copper tube terminal located on the side far from the feeding table to prevent the copper tube terminal located on the side far from the feeding table from falling, so as to ensure that only one copper tube terminal falls into the feeding table each time. When the electromagnetic component is in the de-energized state, the first connecting block is no longer adsorbed by the electromagnetic component, and the reset component resets, driving the first plug rod to extend into the feeding groove to limit the copper tube terminal and prevent the copper tube terminal from falling. At this time, the second plug rod does not extend into the feeding groove.

[0012] Optionally, the pushing mechanism includes a pushing air cylinder connected to the feeding table and a pushing pin for pushing the copper tube terminal to the clamping mechanism. The piston rod of the pushing air cylinder is connected to the pushing pin, the pushing pin is slidably connected to the feeding table, and the pushing mechanism further includes a limiting rod for positioning the copper tube terminal in the clamping mechanism. The limiting rod is located on the side of the clamping mechanism far from the pushing mechanism.

[0013] By adopting the above technical solution, after the copper tube terminal slides into the feeding table, the pushing air cylinder is started, and the piston rod of the pushing air cylinder drives the pushing pin to move towards the side close to the clamping mechanism, pushing the copper tube terminal placed on the feeding table into the clamping mechanism. The clamping mechanism will then clamp the copper tube terminal to limit the copper tube terminal. And the setting of the limiting rod on the side of the clamping mechanism far from the pushing mechanism can play a role in positioning the copper tube terminal. When the copper tube terminal is pushed into the clamping mechanism, the end of the copper tube terminal far from the pushing mechanism will contact the limiting rod, preventing the position of the copper tube terminal from shifting when it is pushed into the clamping mechanism by the pushing pin, which may affect the cutting and pressing of the side wall of the copper tube terminal.

[0014] Optionally, the blanking mechanism includes a column, a blanking air cylinder arranged on the column, and a sliding frame slidably connected in the column and connected to the piston rod of the blanking air cylinder.

[0015] By adopting the above technical solution, when the copper tube terminal is clamped by the clamping mechanism, the blanking air cylinder is started, driving the sliding frame slidably connected to the column to move towards the side close to the cutting mechanism, and then driving the clamping mechanism to move towards the side close to the cutting mechanism, so that the copper tube terminal placed in the clamping mechanism can contact the cutting mechanism to complete the cutting of the side wall of the copper tube terminal.

[0016] Optionally, the clamping mechanism is arranged on the sliding frame. The clamping mechanism includes a clamping cylinder, a first clamping block connected to the piston rod of the clamping cylinder, and a second clamping block rotatably connected to the first clamping block. The clamping mechanism is arranged on the side of the feeding table away from the pushing cylinder.

[0017] By adopting the above technical solution, when the copper tube terminal is not pushed between the first clamping block and the second clamping block, the piston rod of the clamping cylinder pushes the first clamping block, causing the first clamping block to rotate relative to the second clamping block, so that the rotatably connected first clamping block and the second clamping block are separated, and the copper tube terminal can be pushed by the push pin between the first clamping block and the second clamping block. When the copper tube terminal is pushed into the clamping mechanism, the piston rod of the clamping cylinder retracts, driving the first clamping block to move, causing the first clamping block to rotate toward the side close to the second clamping block and closely adhere to the second clamping block, thereby realizing the clamping of the copper tube terminal.

[0018] Optionally, the cutting mechanism includes a cutting motor, a first cutting tooth and a second cutting tooth connected to the output shaft of the cutting motor for opening the copper tube terminal.

[0019] By adopting the above technical solution, when the feeding mechanism drives the clamping mechanism to move toward the side close to the cutting mechanism, the cutting motor is started, the output shaft of the cutting motor rotates, driving the first cutting tooth and the second cutting tooth to rotate. When the copper tube terminal contacts the first cutting tooth and the second cutting tooth, two through grooves can be cut on the side wall of the copper tube terminal.

[0020] Optionally, the ejecting mechanism includes an ejecting seat, an ejecting cylinder arranged on the ejecting seat, an ejecting rod connected to the piston rod of the ejecting cylinder, and an ejecting pin arranged on the ejecting rod. A first limiting seat for the ejecting rod to pass through is provided on the side of the ejecting seat away from the ejecting cylinder, and the ejecting rod is slidably connected to the first limiting seat.

[0021] By adopting the above technical solution, the ejector seat is used to fix the ejector cylinder, the ejector rod and the ejector pin. The first limit seat is used to limit the ejector rod and the ejector pin to ensure that the ejector pin can accurately penetrate into the copper tube terminal. After the first cutting teeth and the second cutting teeth complete the cutting of the side wall of the copper tube terminal, the ejector cylinder is started, and the piston rod of the ejector cylinder pushes the ejector rod to move towards the side close to the first clamping block and the second clamping block, so that the ejector pin passes through the middle of the copper tube terminal to remove the burrs on the copper tube terminal. And when the pressing mechanism completes the pressing of the side wall of the copper tube terminal between the two through grooves, the piston rod of the clamping cylinder pushes the first clamping block, so that the first clamping block rotates relative to the second clamping block, thereby separating the rotationally connected first clamping block and the second clamping block, and the copper tube terminal is no longer clamped by the first clamping block and the second clamping block. The ejector cylinder will drive the ejector pin to move towards the side close to the first clamping block and the second clamping block again and pass through the middle of the copper tube terminal. Since the side wall of the copper tube terminal is pressed by the pressing mechanism, the side wall of the copper tube terminal is recessed inward. When the ejector pin extends into the copper tube terminal, the ejector pin will contact the inwardly recessed side wall of the copper tube terminal and push the copper tube terminal to move away from the first clamping block and the second clamping block, taking the copper tube terminal out between the first clamping block and the second clamping block. Then the piston rod of the ejector cylinder retracts, and the ejector pin no longer extends into the middle of the copper tube terminal, and the copper tube terminal can freely fall to the discharge port.

[0022] Optionally, the pressing mechanism includes a pressing seat, a pressing cylinder arranged on the pressing seat, and a pressing pin connected to the piston rod of the pressing cylinder. A second limit seat for the pressing pin to pass through is arranged on the side of the pressing seat away from the pressing cylinder, and the pressing pin is slidably connected to the second limit seat.

[0023] By adopting the above technical solution, the pressing seat is provided to fix the pressing cylinder and the pressing pin. After the ejector pin removes the burrs on the copper tube terminal, the pressing cylinder is started, and the piston rod of the pressing cylinder drives the pressing pin to move towards the side close to the first clamping block and the second clamping block, and the pressing pin presses on the side wall of the copper tube terminal, so that the side wall of the copper tube terminal between the two through grooves is recessed inward.

[0024] Optionally, the limiting component includes a clamping member detachably connected to the feeding table. The clamping member includes a first clamping plate and a second clamping plate. One ends of the first clamping plate and the second clamping plate are connected, and the sides of the first clamping plate and the second clamping plate close to the ejector pin are in a flared shape.

[0025] By adopting the above technical solution, the clamping member and the feeding table can be detachably connected by bolts, making the connection and disconnection between the clamping member and the feeding table faster and more convenient. After the pressing needle finishes pressing the side wall of the copper tube terminal, the ejector pin will move again toward the side close to the first clamping block and the second clamping block and extend into the copper tube terminal, driving the copper tube terminal to move away from the first clamping block and the second clamping block, so that the copper tube terminal extends into the middle of the first clamping plate and the second clamping plate, causing the first clamping plate and the second clamping plate to separate from each other and extend from the side of the first clamping plate and the second clamping plate that is not in a flared shape. After the copper tube terminal extends out from between the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate will approach each other. When the ejector pin retracts, the copper tube terminal will be blocked by the first clamping plate and the second clamping plate and will not move with the retraction of the ejector pin. When the ejector pin separates from the copper tube terminal, the copper tube terminal will freely fall to the discharge port. The sides of the first clamping plate and the second clamping plate close to the ejector pin are arranged in a flared shape, which is convenient for the copper tube terminal to extend between the first clamping plate and the second clamping plate to ensure the realization of the function of the clamping member.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. By providing a feeding mechanism, a material fixing mechanism, a material clamping mechanism, a material pushing mechanism, a material discharging mechanism, a material cutting mechanism, a material pressing mechanism, a material ejecting mechanism and a limiting mechanism on the machine table, two through grooves can be processed on the side wall of the copper tube terminal, and the side wall of the copper tube terminal between the two grooves is recessed inward.

[0028] 2. The limiting mechanism includes a first clamping plate and a second clamping plate. One end of the first clamping plate and the second clamping plate is connected. The sides of the first clamping plate and the second clamping plate close to the material pushing mechanism are in a flared shape. The setting of the limiting mechanism prevents the copper tube terminal from returning to the material clamping mechanism again with the retraction of the ejector pin when the ejector pin pushes the copper tube terminal out of the material clamping mechanism and retracts, ensuring that the processed copper tube terminal can fall into the discharge port.

A first mating groove 421 is formed on the first clamping block 42, and a second mating groove 431 is formed on the second clamping block 43. The first mating groove 421 and the second mating groove 431 are mutually fitted for placing the copper tube terminals.

[0048] Reference Figure 6 and Figure 8 As shown in Figure 6 and Figure 8 , the cutting mechanism 7 is arranged on the lower side of the second clamping block 43. The cutting mechanism 7 includes a cutting motor 71, a first cutting tooth 72, and a second cutting tooth 73. The first cutting tooth 72 and the second cutting tooth 73 are connected to the output shaft of the cutting motor 71, and a protective cover 74 is provided outside the first cutting tooth 72 and the second cutting tooth 73. The setting of the protective cover 74 can play a role in protecting the personal safety of the staff, preventing the staff from accidentally touching the first cutting tooth 72 and the second cutting tooth 73 and causing danger.

[0049] Reference Figure 3 As shown in Figure 3 , the pressing mechanism 8 is arranged on the side of the feeding table 24 away from the clamping mechanism 4. The pressing mechanism 8 includes a pressing seat 81, a pressing cylinder 82, and a pressing needle 83. The pressing cylinder 82 is arranged on the pressing seat 81. The piston rod of the pressing cylinder 82 is connected to the pressing needle 83. The pressing seat 81 is also provided with a second limit seat 84. The second limit seat 84 is arranged on the side of the pressure seat away from the pressing cylinder 82. The pressing needle 83 passes through the second limit seat 84 and is slidably connected to the second limit seat 84. The ejecting mechanism 9 is arranged on the side of the second cutting tooth 73 away from the vibrating disk 21. The ejecting mechanism 9 includes an ejecting seat 91, an ejecting cylinder 92, and an ejecting rod 93. The ejecting cylinder 92 is arranged on the ejecting seat 91. The piston rod of the ejecting cylinder 92 is connected to the ejecting rod 93. The ejecting seat 91 is also provided with a first limit seat 95. The first limit seat 95 is arranged on the side of the ejecting seat 91 away from the ejecting cylinder 92. The ejecting rod 93 passes through the first limit seat 95 and is slidably connected to the first limit seat 95. One end of the ejecting rod 93 away from the ejecting cylinder 92 is connected with an ejecting needle 94.

[0050] Reference Figure 9, the limiting mechanism 10 includes a clamping member 101 detachably connected to the feeding table 24 by bolts. The clamping member 101 includes a first clamping plate 102 and a second clamping plate 103. The first clamping plate 102 and the second clamping plate 103 are close to each other, and one end of the first clamping plate 102 and the second clamping plate 103 close to the feeding table 24 is fixedly connected. The sides of the first clamping plate 102 and the second clamping plate 103 away from the pushing pin 52 are in a flared shape.

[0051] Refer to Figure 3 and Figure 4 , when the copper tube terminals need to be processed, first, the vibrating disk 21 needs to be started. The vibrating disk 21 vibrates, so that the copper tube terminals enter the feeding tube 22 in sequence. The copper tube terminals entering the feeding tube 22 will enter the feeding groove 231 in sequence.

[0052] Refer to Figure 4 and Figure 5 , the first insertion rod 34 and the second insertion rod 38 can play a role in fixing the copper tube terminals. When the electromagnetic member 31 is in the energized state, the electromagnetic member 31 adsorbs the first connection block 32 and moves it toward the side close to the electromagnetic member 31, driving the connecting rod 33 and the first insertion rod 34 to move toward the side close to the electromagnetic member 31. The return spring 371 is pushed. At this time, the first insertion rod 34 does not extend into the feeding groove 231, and the copper tube terminal located on the side close to the feeding table 24 and in contact with the first insertion rod 34 can fall. And at this time, the second insertion rod 38 will extend into the feeding groove 231 and contact the copper tube terminal located on the side away from the feeding table 24 to prevent the copper tube terminal located on the side away from the feeding table 24 from falling, so as to ensure that only one copper tube terminal falls into the feeding table 24 each time. When the electromagnetic member 31 is in the de-energized state, the first connection block 32 is no longer adsorbed by the electromagnetic member 31, and the return spring 371 resets, driving the first insertion rod 34 to extend into the feeding groove 231 to limit the copper tube terminal and prevent the copper tube terminal from falling. At this time, the second insertion rod 38 does not extend into the feeding groove 231.

[0053] Refer to Figure 3 and Figure 4 , because one end of the feeding column 23 away from the feeding tube 22 abuts against the feeding table 24, and the feeding column 23 is inclined. When the electromagnetic member 31 is in the energized state, the first insertion rod 34 no longer limits the copper tube terminal, and the copper tube terminal will slide into the placement groove 241 opened on the feeding table 24 under the action of gravity.

[0054] Refer to Figure 6 and Figure 8, after the copper tube terminal slides into the placement groove 241, the piston rod of the clamping cylinder 41 pushes the first clamping block 42, causing the first clamping block 42 to rotate relative to the second clamping block 43, so that the rotationally connected first clamping block 42 and second clamping block 43 are separated from each other, that is, the first fitting groove 421 and the second fitting groove 431 are separated from each other. Then the pushing cylinder 51 is activated, and the piston rod of the pushing cylinder 51 drives the push pin 52 to move towards the side close to the first clamping block 42 and the second clamping block 43, and pushes the copper tube terminal placed on the feeding table 24 into the first fitting groove 421 and the second fitting groove 431. At this time, the piston rod of the clamping cylinder 41 retracts, driving the first clamping block 42 to move, causing the first clamping block 42 to rotate towards the side close to the second clamping block 43 and press against the second clamping block 43, thus realizing the clamping of the copper tube terminal. And a limiting rod 53 is provided on the side of the first clamping block 42 and the second clamping block 43 away from the push pin 52. The setting of the limiting rod 53 can play a role in positioning the copper tube terminal. When the copper tube terminal is pushed into the first fitting groove 421 and the second fitting groove 431, the end of the copper tube terminal away from the push pin 52 will abut against the limiting rod 53, preventing the position of the copper tube terminal from shifting relative to the first clamping block 42 and the second clamping block 43 when the copper tube terminal is pushed into the first fitting groove 421 and the second fitting groove 431 by the push pin 52, which may affect the cutting and pressing of the side wall of the copper tube terminal.

[0055] Refer to Figure 6 and Figure 8 , when the copper tube terminal is clamped by the first clamping block 42 and the second clamping block 43, the blanking cylinder 62 is activated, driving the sliding frame 63 to move towards the side close to the first cutting tooth 72 and the second cutting tooth 73, and further driving the clamping mechanism 4 to move towards the side close to the first cutting tooth 72 and the second cutting tooth 73. At the same time when the blanking cylinder 62 is activated, the cutting motor 71 is activated, and the output shaft of the cutting motor 71 rotates, driving the first cutting tooth 72 and the second cutting tooth 73 to rotate. When the copper tube terminal contacts the first cutting tooth 72 and the second cutting tooth 73, two through grooves can be cut on the side wall of the copper tube terminal.

[0056] Refer to Figure 8 and Figure 11 , after the first cutting tooth 72 and the second cutting tooth 73 complete the work of cutting two through grooves on the side wall of the copper tube terminal, the ejecting cylinder 92 is activated, and the piston rod of the ejecting cylinder 92 pushes the ejecting rod 93 towards the side close to the first clamping block 42 and the second clamping block 43, thereby driving the ejecting pin 94 to move towards the side close to the first clamping block 42 and the second clamping block 43, so that the ejecting pin 94 passes through the middle of the copper tube terminal to remove the burrs on the copper tube terminal. The ejecting seat 91 can play a role in fixing the ejecting cylinder 92, the ejecting rod 93 and the ejecting pin 94, and the first limiting seat 95 is used to limit the ejecting rod 93 to ensure that the ejecting pin 94 can accurately penetrate into the copper tube terminal.

[0057] Reference Figure 11 When the burr removal work of the copper tube terminal is completed, the pressing cylinder 82 is started, and the piston rod of the pressing cylinder 82 drives the pressing needle 83 to move toward the side close to the first clamping block 42 and the second clamping block 43. The pressing needle 83 presses on the side wall of the copper tube terminal, so that the side wall of the copper tube terminal between the two through grooves is concave inward. The setting of the pressing seat 81 can fix the pressing cylinder 82 and the pressing needle 83.

[0058] Reference Figure 8 and Figure 11 After the pressing needle 83 completes the pressing of the side wall of the copper tube terminal between the two through grooves, the piston rod of the clamping cylinder 41 pushes the first clamping block 42, so that the first clamping block 42 rotates relative to the second clamping block 43, so that the first clamping block 42 and the second clamping block 43 that are rotatably connected are separated, and the copper tube terminal is no longer clamped by the first clamping block 42 and the second clamping block 43, and the ejecting cylinder 92 will drive the ejector pin 94 to move toward the side close to the first clamping block 42 and the second clamping block 43 again, and pass through the middle of the copper tube terminal. Because the side wall of the copper tube terminal is pressed by the pressing mechanism 8, the side wall of the copper tube terminal is concave inwardly. When the ejector pin 94 extends into the copper tube terminal, the ejector pin 94 will contact the concave side wall of the copper tube terminal and push the copper tube terminal to move toward the side away from the first clamping block 42 and the second clamping block 43, and bring the copper tube terminal out from between the first clamping block 42 and the second clamping block 43.

[0059] Reference Figure 10 and Figure 11 As the ejector pin 94 moves, the ejector pin 94 drives the copper tube terminal, so that the copper tube terminal extends into the middle of the first clamping plate 102 and the second clamping plate 103, so that the first clamping plate 102 and the second clamping plate 103 are separated from each other, and extends from the first clamping plate 102 and the second clamping plate 103 away from the ejection cylinder 92. After the copper tube terminal extends from between the first clamping plate 102 and the second clamping plate 103, the first clamping plate 102 and the second clamping plate 103 will approach each other, and then the piston rod of the ejection cylinder 92 will retreat, and the copper tube terminal will be blocked by the first clamping plate 102 and the second clamping plate 103, and will not move with the retreat of the ejector pin 94. When the ejector pin 94 is separated from the copper tube terminal, the copper tube terminal will freely fall to the discharge port 11, and the processing of the copper tube terminal can be completed once. The first clamping plate 102 and the second clamping plate 103 are arranged in a bell-mouth shape on one side close to the ejector pin 94, so that the copper tube terminal can be inserted between the first clamping plate 102 and the second clamping plate 103 to ensure the function of the clamping member 101. The clamping member 101 and the feed table 24 can be detachably connected by bolts, so that the connection and disassembly between the clamping member 101 and the feed table 24 is faster and more convenient.

[0060] The implementation principle of the embodiments of this application is as follows: When processing copper tube terminals, the feeding mechanism 2 needs to be started first to achieve the feeding of copper tube terminals. When the solid material mechanism 3 no longer restricts the copper tube terminals, the copper tube terminals can fall. The solid material mechanism 3 can ensure that only one copper tube terminal falls each time. After the feeding of the copper tube terminals is completed, the pushing mechanism 5 will push the copper tube terminals into the clamping mechanism 4, and the clamping mechanism 4 will clamp the copper tube terminals. Then, the cutting mechanism 7 is started, and at the same time, the discharging mechanism 6 will drive the clamping mechanism 4 to move towards the side close to the cutting mechanism 7. When the copper tube terminals contact the cutting mechanism 7, the cutting mechanism 7 can cut two through grooves on the side wall of the copper tube terminals. After the work of cutting two through grooves on the side wall of the copper tube terminals is completed, the ejecting mechanism 9 is started. The ejecting mechanism 9 moves towards the side close to the copper tube terminals and passes through the copper tube terminals to remove the burrs on the inner wall of the copper tube terminals. Then, the pressing mechanism 8 is started. The pressing mechanism 8 moves towards the side close to the copper tube terminals and pushes the side wall of the copper tube terminals between the two through grooves towards the inside of the copper tube terminals, making the side wall of the copper tube terminals between the two through grooves sink inward. Then, the clamping mechanism 4 releases the copper tube terminals, and the ejecting mechanism 9 is started again to eject the copper tube terminals placed in the clamping mechanism 4 out of the clamping mechanism 4. The copper tube terminals moving with the ejecting mechanism 9 will enter the limiting mechanism 10 and be limited. When the ejecting mechanism 9 retracts, due to the limitation of the limiting mechanism 10, the copper tube terminals will not retract with the retraction of the ejecting mechanism 9, and the copper tube terminals will freely fall to the discharge port 11, thus completing the processing of the copper tube terminals once.

The same components are represented by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
