Description

Technical Field

[0001] This invention relates to the field of copper rod cutting technology, and more particularly to a cutting device for copper rods. Background Technology

[0002] During the production and forming process, copper rods usually need to be cut to the required length according to actual needs.

[0003] However, during the processing of copper rods, the specifications of the copper rods vary. In traditional cutting, the copper rods usually need to be fixed to ensure stability during the cutting process. However, due to the different lengths of the copper rods, there is a certain deviation when fixing them, which leads to vibration during the cutting process and affects the stability of the cutting. At the same time, the cutting process often adopts the method of cutting one by one, which cannot meet the batch processing of copper rods of different specifications, thus affecting the actual cutting efficiency.

[0004] Therefore, we propose a cutting device for copper rods. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting device for copper rods.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device for copper rods, comprising:

[0008] The workbench has a recessed section at the top center.

[0009] The contact assembly comprises several sets, fixedly installed in an array on both sides of the top of the workbench. Each contact assembly includes a guide rail with an adjustable fastening adjustment component slidably mounted on it. The top of the guide rail has a one-way rack that engages with the fastening adjustment component, effectively adjusting and clamping its position. The fastening adjustment component has an adjustable rotary copper rod fastening mechanism, which includes a rotatable inner conical sleeve. Conical grooves are formed on the sides of the inner conical sleeves that are close to each other. Because the inner side of the inner conical sleeve has a conical groove, when the diameter of the copper rod is smaller than the maximum diameter of the conical groove, a region inside the inner conical sleeve matches the size of the copper rod, thus achieving effective contact at the ends of the copper rod. This prevents the copper rod from eccentrically wobbling during subsequent cutting, allowing the corresponding inner conical sleeves to effectively clamp and fix copper rods of different diameters, facilitating subsequent cutting.

[0010] The cutting assembly is fixedly installed in the recess of the workbench. It includes a mounting frame with an elastic pressing strip that presses the copper rod. At the top of the mounting frame, there is a reciprocating mechanism for driving the elastic pressing strip to move. The reciprocating mechanism drives the elastic pressing strip to move, and the elastic pressing strip that presses the copper rod with friction drives the copper rod to rotate back and forth. The middle of the mounting frame is equipped with a height-adjustable strip-shaped cutting blade, which effectively cuts the rotating copper rod.

[0011] The push rod motor is provided in several groups, and the push rod motor is set in correspondence with the contact component. It is fixedly installed in the middle of the top of the recess on the worktable. The output shaft of the push rod motor is vertically upward and is equipped with a grinding disc, which makes it convenient for the push rod motor to drive the grinding disc to rise and perform surface friction treatment on the cut part of the copper rod to achieve the purpose of effectively deburring.

[0012] As a preferred technical solution of this application, the guide rail is T-shaped, and a one-way rack is fixedly installed on the top of the guide rail;

[0013] The fastening adjustment component includes a sliding cover that is slidably sleeved on the outside of the guide rail. A telescopic rod is inserted through the middle of the top of the sliding cover, and the bottom end of the telescopic rod passes through the top of the sliding cover. The bottom end of the telescopic rod is fixedly connected to a locking tooth block that is adapted to a one-way rack. Thus, during movement, the locking tooth block and the one-way rack are engaged to effectively lock the position of the fastening adjustment component. A return spring is sleeved on the outside of the telescopic rod and fixedly connected to the top of the sliding cover. Thus, during movement, the action of the return spring effectively achieves automatic engagement between the locking tooth block and the one-way rack, ensuring effective locking of the position.

[0014] As a preferred technical solution of this application, the bottom end of the sliding cover is provided with several grooves, and embedded ball bearings that contact the top of the worktable are embedded in the grooves, thereby effectively ensuring the smoothness of the fastening adjustment component during the position adjustment process.

[0015] As a preferred technical solution of this application, the rotary copper rod fastening mechanism is fixedly installed on one side of the top of the sliding cover. The rotary copper rod fastening mechanism includes a fixed seat fixedly installed on the top of the sliding cover. The inner side of the fixed seat is provided with threads, and the central angle of the fixed seat is greater than 180°.

[0016] The inner thread of the fixed seat is fitted with a fine-adjusting screw ring. By setting the central angle of the fixed seat to be greater than 180°, the fine-adjusting screw ring is prevented from easily falling out of the fixed seat. The inner side of the fine-adjusting screw ring is rotatably provided with an inner conical sleeve, which is used to clamp the copper rod.

[0017] The threaded engagement between the fixed seat and the fine-tuning ring allows the fine-tuning ring to be finely adjusted inside the fixed seat, better adapting to copper rods of different lengths and facilitating the fixing of the copper rods.

[0018] As a preferred technical solution of this application, the cutting assembly includes a mounting frame fixedly installed in the recess of the workbench, and the lower part of the vertical support arm of the mounting frame is provided with two sets of through openings, and the elastic pressing strip passes through the openings;

[0019] The reciprocating mechanism includes two sets of reciprocating screws rotatably mounted on the upper inner side of the mounting frame. Screw nut sleeves are threaded on the outer side of the reciprocating screws, and a sliding groove for the screw nut sleeves to slide is opened on the inner wall of the top of the mounting frame. Stable back-and-forth movement is achieved under the helical cooperation between the screw nut sleeves and the reciprocating screws. A drive motor is mounted on one side of the mounting frame, and the output shaft of the drive motor is coaxially connected to one of the reciprocating screws. The other end of the reciprocating screw passes through the mounting frame and is coaxially connected to a synchronous pulley. A synchronous belt is sleeved on the outer side of the synchronous pulley, so that the two sets of elastic pressing strips move synchronously under the action of the synchronous belt, providing sufficient power for subsequent friction.

[0020] The bottom end of the lead screw nut sleeve is evenly connected with several sets of elastic telescopic rods that are fixedly connected to the elastic pressing strip. Through the setting of the elastic telescopic rods, the bottom end of the elastic pressing strip can effectively abut against the copper rod below, so that the copper rod can be rotated by friction during the reciprocating motion of the lead screw nut sleeve driving the elastic pressing strip.

[0021] As a preferred technical solution of this application, a pneumatic push rod is fixedly installed at the top of the mounting frame. The output shaft of the pneumatic push rod passes through the mounting frame and is connected to a strip-shaped cutting blade arranged parallel to the elastic pressing strip. The pneumatic push rod drives the strip-shaped cutting blade to move downward, so as to make contact with the rotating copper rod and thus perform batch cutting of the copper rod.

[0022] As a preferred technical solution of this application, the upper part of the mounting bracket is provided with a vertical groove, and a stabilizing component connected to the strip cutting blade is provided in the vertical groove. The stabilizing component includes a guide rod fixedly installed in the vertical groove, a buffer sleeve is sleeved on the outside of the guide rod, and the buffer sleeve is fixedly connected to the strip cutting blade by a connecting rod. A buffer spring is sleeved on the outside of the guide rod, and the two ends of the buffer spring are fixedly connected to the vertical groove and the buffer sleeve respectively, thereby ensuring the stability of the strip cutting blade during the cutting operation.

[0023] As a preferred technical solution of this application, the workbench has two sets of symmetrically arranged inclined chip removal channels at the recess, which effectively ensures the discharge of copper chips during the copper rod cutting process and ensures a clean working environment.

[0024] The beneficial effects of this invention are as follows:

[0025] 1. Through the cooperation of the rotating copper rod fastening mechanism on the fastening adjustment component, the copper rods of different diameters can be effectively fixed by contact. It has good adaptability during the cutting operation. Furthermore, the position adjustment of the fastening adjustment component itself, combined with the thread operation of the fine-tuning screw ring and the fixed seat, can achieve precise distance adjustment, better locking of copper rods of different sizes, and facilitate subsequent cutting processing.

[0026] 2. During the cutting process, the push rod motor and grinding disc effectively perform friction polishing on the cut, thereby improving the quality of product processing;

[0027] 3. During the cutting process, since the centerline height of the fastening adjustment components is consistent, when processing copper rods of different diameters in the same batch, the copper rods themselves rotate, and the strip cutting blade only needs to cut down to the centerline height of the fastening adjustment components. This effectively achieves the cutting of batch copper rods, and the cutting operation is not affected by the different specifications of the copper rods during the batch operation, which greatly improves the efficiency of the actual cutting operation.

[0028] In summary, this application can effectively resist copper rods of different diameters and lengths during actual use, facilitating stable processing. During cutting operations, it can perform synchronous cutting operations regardless of the different diameters of the copper rods, improving cutting efficiency. Furthermore, the cut surfaces are polished during the cutting process to reduce burrs and improve product quality. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Reference Figures 1-8 A cutting device for copper rods, comprising:

[0040] Workbench 1, with a notch at the top center;

[0041] The contact assembly 2 comprises several sets, fixedly installed in an array on both sides of the top of the workbench 1. The contact assembly 2 includes a guide rail 21, on which an adjustable fastening adjustment member 22 is slidably mounted. The top of the guide rail 21 has a one-way rack 23 that cooperates with the fastening adjustment member 22, used to effectively adjust and lock the position of the fastening adjustment member 22. The fastening adjustment member 22 has an adjustable rotary copper rod fastening mechanism 225, and the rotary copper rod fastening mechanism 225 has a rotatable inner conical sleeve 22. 53. The inner conical sleeves 2253 have conical grooves on their adjacent sides. Since the inner side of the inner conical sleeve 2253 is a conical groove, when the diameter of the copper rod is smaller than the maximum diameter of the conical groove, there is a region inside the inner conical sleeve 2253 whose size matches the size of the copper rod. This allows for effective contact between the ends of the copper rod, preventing the copper rod from eccentrically wobbling during subsequent cutting. This also enables the corresponding inner conical sleeves 2253 to effectively clamp and fix copper rods of different diameters, facilitating subsequent cutting.

[0042] The cutting assembly 3 is fixedly installed in the recess of the workbench 1. It includes a mounting frame 31, on which an elastic pressing strip 32 is provided to press the copper rod. A reciprocating mechanism is provided at the top of the mounting frame 31 to drive the elastic pressing strip 32 to move. The reciprocating mechanism drives the elastic pressing strip 32 to move. With the help of friction, the elastic pressing strip 32 presses the copper rod and drives the copper rod to rotate back and forth. The middle part of the mounting frame 31 is provided with a height-adjustable strip-shaped cutting blade 39, which effectively realizes the cutting of the rotating copper rod.

[0043] The push rod motor 4 is provided in several groups. The push rod motor 4 is correspondingly set with the contact component 2 and is fixedly installed in the middle of the top of the recess on the worktable 1. The output shaft of the push rod motor 4 is vertically upward and is equipped with a grinding disc 5, which facilitates the push rod motor 4 to drive the grinding disc 5 to rise and perform surface friction treatment on the copper rod cutting area to achieve the purpose of effectively deburring.

[0044] The workbench 1 has two sets of symmetrically arranged inclined chip removal channels at the notch, which effectively ensures the removal of copper chips during the copper rod cutting process and ensures a clean working environment.

[0045] Reference Figures 3-4 The guide rail 21 is T-shaped, and the one-way rack 23 is fixedly installed on the top of the guide rail 21;

[0046] The fastening adjustment component 22 includes a sliding cover 221 that is slidably sleeved on the outside of the guide rail 21. A telescopic rod 223 is inserted through the middle of the top of the sliding cover 221. The bottom end of the telescopic rod 223 passes through the top of the sliding cover 221, and a snap-fit ​​tooth block 224 that is adapted to the one-way rack 23 is fixedly connected to the bottom end of the telescopic rod 223. Thus, during the movement, the snap-fit ​​tooth block 224 and the one-way rack 23 are effectively engaged to lock the position of the fastening adjustment component 22. A return spring 222 that is fixedly connected to the top of the sliding cover 221 is sleeved on the outside of the telescopic rod 223. Thus, during the movement, the snap-fit ​​tooth block 224 and the one-way rack 23 are automatically engaged through the action of the return spring 222 to ensure that the position is effectively locked and tightened.

[0047] The bottom of the sliding cover 221 is provided with several grooves, and embedded balls that contact the top of the worktable 1 are embedded in the grooves, thereby effectively ensuring the smoothness of the fastening adjustment component 22 during the position adjustment process.

[0048] Reference Figure 5 The rotary copper rod fastening mechanism 225 is fixedly installed on one side of the top of the sliding cover 221. The rotary copper rod fastening mechanism 225 includes a fixed seat 2251 fixedly installed on the top of the sliding cover 221. The inner side of the fixed seat 2251 is provided with threads, and the central angle of the fixed seat 2251 is greater than 180°.

[0049] The inner thread of the fixed seat 2251 is fitted with a fine-tuning screw ring 2252. By setting the central angle of the fixed seat 2251 to be greater than 180°, the phenomenon of the fine-tuning screw ring 2252 easily falling out of the fixed seat 2251 is avoided. The inner side of the fine-tuning screw ring 2252 is rotatably provided with an inner conical sleeve 2253, which is used to clamp the copper rod.

[0050] By engaging the fixed base 2251 with the fine-tuning ring 2252, the fine-tuning ring 2252 can be finely adjusted inside the fixed base 2251, better adapting to copper rods of different lengths and facilitating the fixing of the copper rods.

[0051] Reference Figures 6-8 The cutting assembly 3 includes a mounting bracket 31 fixedly installed in the recess on the workbench 1. The lower part of the vertical support arm of the mounting bracket 31 is provided with two sets of through openings, and the elastic pressing strip 32 passes through the openings.

[0052] The reciprocating mechanism includes two sets of reciprocating screws 311 rotatably mounted on the upper inner side of the mounting frame 31. Screw nut sleeves 310 are threaded on the outer side of the reciprocating screws 311, and the inner wall of the top of the mounting frame 31 is provided with a sliding groove for the sliding of the screw nut sleeves 310. Under the helical cooperation between the screw nut sleeves 310 and the reciprocating screws 311, the screw nut sleeves 310 can move back and forth stably. A drive motor 35 is mounted on one side of the mounting frame 31. The output shaft of the drive motor 35 is coaxially connected to one set of reciprocating screws 311. The other end of the reciprocating screws 311 passes through the mounting frame 31 and is coaxially connected to a synchronous pulley 313. A synchronous belt 312 is sleeved on the outer side of the synchronous pulley 313. Under the action of the synchronous belt 312, the two sets of elastic pressing strips 32 can move synchronously, providing sufficient power for subsequent friction.

[0053] The bottom end of the lead screw nut sleeve 310 is evenly connected with several sets of elastic telescopic rods 34 that are fixedly connected to the elastic pressing strip 32. By setting the elastic telescopic rods 34, the bottom end of the elastic pressing strip 32 can effectively abut against the copper rod below, so that the copper rod can be rotated by friction during the reciprocating motion of the lead screw nut sleeve 310 driving the elastic pressing strip 32.

[0054] A pneumatic push rod 33 is fixedly installed at the top of the mounting frame 31. The output shaft of the pneumatic push rod 33 passes through the mounting frame 31 and is connected to a strip-shaped cutting blade 39 arranged parallel to the elastic pressing strip 32. The pneumatic push rod 33 drives the strip-shaped cutting blade 39 to move downward, so as to make contact with the rotating copper rod and thus perform batch cutting of the copper rod. The upper part of the mounting frame 31 is provided with a vertical groove, and a stabilizing component connected to the strip-shaped cutting blade 39 is provided in the vertical groove. The stabilizing component includes a guide rod 37 fixedly installed in the vertical groove. A buffer sleeve 38 is sleeved on the outside of the guide rod 37, and the buffer sleeve 38 is fixedly connected to the strip-shaped cutting blade 39 by a connecting rod. A buffer spring 36 is sleeved on the outside of the guide rod 37. The two ends of the buffer spring 36 are fixedly connected to the vertical groove and the buffer sleeve 38 respectively, so as to ensure the stability of the strip-shaped cutting blade 39 during the cutting operation.

[0055] Workflow: First, the copper rod to be cut is clamped between two sets of corresponding rotary copper rod fastening mechanisms 225. During operation, by sliding the fastening adjustment piece 22, the two sets of rotary copper rod fastening mechanisms 225 are gradually covered on both ends of the copper rod. Under the action of the clamping tooth block 224, the position of the fastening adjustment piece 22 is initially locked. Then, when the distance is finely adjusted to ensure that the copper rod is effectively clamped, the fine adjustment screw ring 2252 is rotated to drive the inner conical sleeve 2253 to screw in in a spiral manner, thereby achieving more precise position adjustment and realizing effective clamping and resistance of the copper rod.

[0056] Then, during cutting, the push rod motor 4 is activated first, causing the abrasive disc 5 to move upward until its upper surface is flush with the lower surface of the copper rod. Then, under the action of the upper elastic telescopic rod 34, the bottom end of the elastic pressing strip 32 makes pressure contact with the upper surface of the copper rod. Next, the drive motor 35 is activated, causing the reciprocating mechanism to move the elastic pressing strip 32 back and forth. As the elastic pressing strip 32 moves back and forth, the friction between the elastic pressing strip 32 and the copper rod causes the copper rod to rotate periodically. At the same time, the pneumatic push rod 33 is activated to gradually lower the strip cutting blade 39. With the continuous rotation of the copper rod and the stable downward pressure of the strip cutting blade 39, the cutting operation of the copper rod is effectively achieved. During the cutting process, the burrs generated at the cut are removed by the friction of the abrasive disc 5 below, effectively improving the quality of the cut product.

[0057] In practical use, this invention effectively achieves the contact fixation of copper rods of different diameters through the cooperation of the rotary copper rod fastening mechanism 225 on the fastening adjustment component 22. It has good adaptability during the cutting operation. Furthermore, the position adjustment of the fastening adjustment component 22 itself, combined with the thread operation of the fine-tuning screw ring 2252 and the fixed seat 2251, enables precise distance adjustment, which better locks copper rods of different sizes, facilitating subsequent cutting processing.

[0058] During the cutting process, the push rod motor 4 and the abrasive disc 5 are used to effectively perform friction polishing on the cut, thereby improving the quality of product processing.

[0059] During the cutting process, since the centerline height of the fastening adjustment component 22 is consistent, when processing copper rods of different diameters in the same batch, the copper rods themselves rotate, and the strip cutting blade 39 only needs to cut down to the centerline height of the fastening adjustment component 22. This effectively achieves the cutting of batch copper rods, and the cutting operation is not affected by the different specifications of the copper rods during the batch operation, which greatly improves the efficiency of the actual cutting operation.
