Technical Field

[0001] This utility model relates to the technical field of metal connector production equipment, specifically a cutting device for metal connector production. Background Technology

[0002] In the production of metal connectors, the cutting of metal rods is a core pre-process. Rods of different diameters need to be precisely cut according to the specifications of the connectors, and the stability of conveying and clamping must be ensured to improve production efficiency.

[0003] However, existing metal rod cutting devices have obvious adaptability defects: most devices use clamping components and conveying channels of fixed size, which can only be adapted to rods of a single diameter. When switching to rods of different specifications, it is necessary to disassemble and replace the clamping components and adjust the conveying structure. The operation is cumbersome and time-consuming, which seriously restricts production efficiency. This makes it difficult for existing devices to meet the cutting needs of rods of multiple specifications in the production of metal connectors. There is an urgent need to optimize adaptability and ease of operation. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a cutting device for the production of metal connectors, including a processing table 1, a positioning seat 2 is provided at the front and rear of the upper end of the processing table 1, a control box 14 is fixedly installed at the upper end of the processing table 1, the middle part of the positioning seat 2 is provided with a slot 3, the front end of the slot 3 is provided with a groove 4, a first cylindrical block 5 is provided in the slot 3, the front end of the first cylindrical block 5 is provided with a second cylindrical block 6, the second cylindrical block 6 is threadedly connected to the groove 4, and a through hole 9 is provided at the center of both the first cylindrical block 5 and the second cylindrical block 6.

[0023] A lifting assembly 10 is provided on the positioning seat 2 at the front end of the processing table 1. The lifting assembly 10 is fixed above the positioning seat 2 by a support rod. A cutter 11 is provided at the output end of the lifting assembly 10. The cutter 11 is located at the front end of the positioning seat 2.

[0024] Above the processing table 1, a support frame 15 is located between two positioning seats 2. Multiple support rods are provided on both sides of the support frame 15. The bottom ends of the support rods are fixed to the upper end of the processing table 1 by screws. Multiple auxiliary wheels 17 are symmetrically arranged on the left and right sides of the lower end of the support frame 15, and two drive wheels 18 are symmetrically arranged on the left and right sides. The auxiliary wheels 17 and drive wheels 18 are provided with arc-shaped grooves on their periphery. A first vertical shaft 16 is vertically arranged at the upper end of the auxiliary wheels 17. The top end of the first vertical shaft 16 is rotatably connected to the support frame 15. A second vertical shaft 19 is vertically arranged at the upper end of the first vertical shaft 16, passing through the support frame 15. The second vertical shaft 19 is rotatably connected to the support frame 15 by bearings. A motor 21 is fixedly arranged above the support frame 15. A gear 20 is fixedly arranged at the top end of the second vertical shaft 19. The two gears 20 mesh with each other. The output end of the motor 21 is provided with a drive shaft connected to one of the second vertical shafts 19.

[0025] First, fix the processing table 1 horizontally. Install positioning seats 2 on the front and back sides of the upper end of the processing table 1 respectively. A slot 3 is opened in the middle of the positioning seat 2, and a groove 4 is set at the front end of the slot 3.

[0026] The first cylindrical block 5 is inserted into the empty groove 3, and the second cylindrical block 6 at its front end is threadedly connected to the groove 4.

[0027] The lifting assembly 10 is fixed above the positioning seat 2 at the front end of the processing table 1 by a support rod. The output end of the lifting assembly 10 is equipped with a cutter 11. The two sides of the cutter 11 are inserted into the positioning grooves 13 of the positioning frame 12 to ensure smooth sliding.

[0028] The metal rod is inserted through the through hole 9 of the first cylindrical block 5 of the rear positioning seat 2, and then passes between the auxiliary wheel 17 and the drive wheel 18 below the support frame 15, so that the outer wall of the rod fits into the arc groove, and then exits through the through hole 9 of the first cylindrical block 5 of the front positioning seat 2.

[0029] At this time, the drive wheel 18 and the auxiliary wheel 17 generate friction with the rod through the arc groove, providing power for subsequent conveying.

[0030] Start the motor 21. The motor 21 drives one of the second vertical shafts 19 to rotate through the transmission shaft. The gear 20 meshes with the other second vertical shaft 19 to rotate synchronously, thereby driving the drive wheel 18 to rotate and moving the metal rod forward a specified distance.

[0031] Two positioning frames 12 are provided on the positioning seat 2 at the front end of the processing table 1. The positioning frame 11 is provided with a positioning groove 13 on the inner side. The two sides of the cutting blade 11 are inserted into the positioning groove 13 and slide with the positioning frame 12.

[0032] Subsequently, the lifting assembly 10 is activated, pushing the cutter 11 to slide downward along the positioning groove 13 of the positioning frame 12 to cut the rod at the front end of the positioning seat 2.

[0033] The first cylindrical block 5 is inserted into the slot 3 and fits tightly against the inner wall of the slot 3. The second cylindrical block 6 is inserted into the groove 4. The front end of the second cylindrical block 6 is flush with the front end of the positioning seat 2. The second cylindrical block 6 and the first cylindrical block 5 are an integral structure. The front end of the second cylindrical block 6 is provided with a cavity 7. Multiple toggle blocks 8 are fixedly arranged in the cavity 7.

[0034] When it is necessary to process rods of different diameters, the second cylindrical block 6 is rotated by the actuating block 8 on the front positioning seat 2, and it is rotated out of the groove 4. The first cylindrical block 5 is pulled out of the empty groove 3 and replaced with a combination of the first cylindrical block 5 and the second cylindrical block 6 with the inner diameter of the through hole 9.

[0035] Loosen the screws at the bottom of the support rod, remove the original support frame 15, and replace it with a new support frame 15 that is compatible with the specifications of the auxiliary wheel 17 and the drive wheel 18. Ensure that the arc groove fits the outer wall of the rod, and then fix the support rod again to continue the operation.

[0036] The positioning groove 13 of the positioning frame 12 guides and limits the cutter 11, preventing the cutter 11 from deviating when it is raised or lowered, and ensuring the perpendicularity of the cutting surface.

[0037] Multiple bearings are embedded in the support frame 15. The outer ring of the bearing is interference-fitted with the support frame 15. The first vertical shaft 16 and the second vertical shaft 19 both pass through the inner ring of the bearing and are interference-fitted with the inner ring of the bearing.

[0038] The auxiliary wheel 17 and the drive wheel 18 are connected to the support frame 15 through the first vertical shaft 16, the second vertical shaft 19 and the bearing. The gear 20 meshes and drives to ensure that the speed of the drive wheels 18 on both sides is consistent. With the help of the arc groove to stably clamp the rod, the shaking during the conveying process is effectively reduced, and the cutting length accuracy is significantly improved.

[0039] The interference fit design of the bearing further enhances the stability of the vertical shaft rotation and reduces the impact of mechanical vibration on cutting accuracy.

[0040] The control box 14 integrates electrical equipment control functions, allowing for preset rod conveying distance and cutting frequency to achieve automated operation. The toggle block 8 makes the screwing operation of the first cylindrical block 5 and the second cylindrical block 6 more convenient, allowing for replacement without additional tools. The support frame 15 is connected to the processing table 1 by screws via support rods, making disassembly and assembly simple and significantly reducing downtime for specification adjustments, thus meeting the high-efficiency requirements of multi-specification switching in the mass production of metal connectors.
