Description

[0001] This utility model relates to the field of cable processing technology, specifically to a raw material cutting device for cable production. Background Technology

[0002] Cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. In the cable processing process, in order to obtain cables of appropriate length, raw material cutting equipment for cable production is usually used to cut the raw materials to obtain raw materials of appropriate length for cable assembly.

[0003] When using existing raw material cutting equipment for cable production, the raw material is usually fixed on the processing table with a fixing tool, and then the appropriate length is measured before the cutting disc is driven to rotate and cut the raw material.

[0004] Existing raw material cutting devices for cable production have the following problems: before cutting, a fixing tool is needed to fix the raw material, and after cutting, the raw material needs to be manually released from the fixing tool.

[0008] Furthermore, the positioning mechanism also includes anti-slip protrusions and elastic pads. The lower surface of the pressure plate and the upper surface of the support plate are both provided with evenly distributed arc-shaped grooves. Elastic pads are provided inside the arc-shaped grooves.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This raw material cutting device for cable production has the following advantages:

[0015] When cutting raw materials, the movement of the moving plate drives the pressure plate downward through the connecting plate. When the cutting disc moves to the appropriate position, if the pressure plate and support plate have not yet fixed the raw material, the rotating disc drives the screw to rotate, causing the pressure plate to move downward until the upper and lower elastic pads clamp and fix the raw material. After cutting is completed, the fixing of the raw material is released as the cutting disc moves upward. When cutting the same type of raw material again, it is not necessary to adjust the fixing of the raw material through the adjustment component. The operation is simple and improves the efficiency of raw material cutting. Attached Figure Description

[0024] Please refer to Figures 1-6. This embodiment provides a technical solution: a raw material cutting device for cable production, including a processing table 1, an adjustable movable plate 6 on the upper surface of the processing table 1, a cutting assembly 8 on the lower surface of the movable plate 6, a positioning mechanism 3, and a microcontroller 2. The microcontroller 2 is fixedly connected to the front side of the processing table 1, and its input is electrically connected to an external power source. A support frame 4 is provided on the left side of the upper surface of the processing table 1, and slots 5 are provided on both the front and rear sides of the support frame 4. The movable plate 6 is slidably connected between the two slots 5. An electric push rod 7 is provided in the mounting hole on the upper surface of the support frame 4. The lower end of the telescopic shaft of the electric push rod 7 is fixedly connected to the upper surface of the movable plate 6, and its input is electrically connected to the output of the microcontroller 2. The cutting assembly 8 includes a slide groove 81, a lead screw 82, a slider 83, a cutting disc 84, a motor 85, and a motor 86. The lower surface of the moving plate 6 has a slide groove 81. The lead screw 82 is rotatably connected inside the slide groove 81. The slider 83 is threaded onto the outer surface of the lead screw 82 and slidably connected inside the slide groove 81. The lower end of the slider 83 is rotatably connected to the cutting disc 84 via a rotating shaft. A motor 85 is located on the left side of the slider 83. The right end of the output shaft of the motor 85 is fixedly connected to the left end of the rotating shaft. A motor 86 is located on the front wall of the slide groove 81. The rear end of the output shaft of the motor 86 is fixedly connected to the front end of the lead screw 82. The input ends of the motors 85 and 86 are electrically connected to the input terminals of the microcontroller 2. The output end also includes a length-fixing component 9, which includes a second slide groove 91, a second lead screw 92, a second slider 93, a length-fixing plate 94, a laser rangefinder 95, and a third motor 96. The second slide groove 91 is located on the right side of the upper surface of the processing table 1. The second lead screw 92 is rotatably connected inside the slide groove 91, and the second slider 93 is threadedly connected to the outer surface of the second lead screw 92. The length-fixing plate 94 is located on the upper surface of the second slider 93. The laser rangefinder 95 is located on the front side of the support frame 4, and the third motor 96 is located on the right side of the processing table 1.

The input end of the third motor 96 is electrically connected to the output end of the microcontroller 2. The laser rangefinder 95 is bidirectionally electrically connected to the microcontroller 2. The operator will operate the microcontroller 2 to open the third motor 96. The output shaft of motor 396 drives lead screw 292 to rotate. The rotation of lead screw 292 causes threaded slider 293 to move along slide groove 291, causing fixed length plate 94 to move. The distance is measured by laser rangefinder 95. Laser rangefinder 95 emits a short laser pulse towards fixed length plate 94, and then measures the time it takes for the laser pulse to be emitted, reflected back by fixed length plate 94, and received by laser rangefinder 95. Combined with the speed of laser propagation in air, the distance between laser rangefinder 95 and fixed length plate 94 is calculated, as well as the distance between fixed length plate 94 and cutting disk 84, thus accurately controlling the cutting length of raw materials. After fixed length plate 94 moves to the appropriate position, the raw material is placed on processing table 1 through the arc groove on support plate 36.At this point, the right end of the raw material contacts the left side of the fixed-length plate 94. The electric push rod 7 is activated, and its telescopic shaft drives the moving plate 6 to move towards each other along the slot 5, causing the cutting disc 84 to move downwards. After the raw material is fixed, motor 1 85 is activated. The output shaft of motor 1 85 drives the cutting disc 84 to rotate via a rotating shaft. Motor 2 86 is activated, and its output shaft drives the lead screw 1 82 to rotate. The rotation of lead screw 1 82 causes the threaded slider 1 83 to slide along the slide groove 1 81, causing the rotating cutting disc 84 to move along the slide groove 1 81, thus cutting the fixed raw material.

[0025] Positioning mechanism 3 includes a connecting plate 31, a sliding opening 32, a limiting rod 33, a pressure plate 34, an adjusting component 35, and a support plate 36. Connecting plates 31 are provided on both the left and right sides of the moving plate 6. Sliding openings 32 are provided on both the front and rear sides of the upper surface of the connecting plate 31. Limiting rods 33 are slidably connected inside the sliding openings 32. The lower ends of two adjacent limiting rods 33 are fixedly connected to the upper surface of a pressure plate 34. Adjusting components 35 are provided on the upper surface of the pressure plate 34. Processing table 1 The upper surface of the pressure plate 34 is provided with support plates 36 corresponding to the two pressure plates 34. The positioning mechanism 3 also includes anti-slip protrusions 37 and elastic pads 38 (the elastic pads 38 are rubber elastic pads). The lower surface of the pressure plate 34 and the upper surface of the support plate 36 are both provided with evenly distributed arc-shaped grooves. The interior of each arc-shaped groove is provided with an elastic pad 38. The inner arc surface of each elastic pad 38 is provided with evenly distributed anti-slip protrusions 37. The adjusting component 35 includes a screw 351 and a rotating disk 352. The upper surface of the pressure plate 34 Each component is rotatably connected to a screw 351. The upper end of the outer surface of each screw 351 is threadedly connected to a threaded hole on the upper surface of the connecting plate 31 on the same side. Each screw 351 has a rotating disk 352 at its upper end. The movement of the moving plate 6 drives the pressure plate 34 to move downward through the connecting plate 31. When the cutting disk 84 moves to the appropriate position, if the pressure plate 34 and the support plate 36 have not yet fixed the raw material, the rotating disk 352 is rotated to drive the screw 351 to rotate. Under the restriction of the slider 32 and the limit rod 33, the rotation of the screw 351 drives the pressure plate 34 to move downward until the upper and lower elastic pads 38 clamp and fix the raw material. Due to the presence of the anti-slip protrusions 37, the friction is increased, preventing the raw material from sliding. After the cutting is completed, the moving plate 6 is driven upward by the electric push rod 7, causing the pressure plate 34 to move upward to release the fixing of the raw material. When cutting the same type of raw material again, it is not necessary to adjust it through the adjusting component 35 to fix the raw material.

[0026] The working principle of the raw material cutting device for cable production provided by this utility model is as follows: The operator turns on the motor 3 96 by controlling the microcontroller 2. The output shaft of the motor 3 96 drives the lead screw 2 92 to rotate. The rotation of the lead screw 2 92 drives the threaded slider 2 93 to move along the slide groove 2 91, causing the fixed length plate 94 to move. The distance is measured by the laser rangefinder 95. The laser rangefinder 95 emits a short laser pulse towards the fixed length plate 94, and then measures the time taken from the emission of the laser pulse to its reflection by the fixed length plate 94 and its reception by the laser rangefinder 95. In between, combining the speed of laser propagation in air, the distance between the laser rangefinder 95 and the fixed-length plate 94 is calculated, and the distance between the fixed-length plate 94 and the cutting disc 84 is obtained, thereby precisely controlling the cutting length of the raw material. After the fixed-length plate 94 moves to the appropriate position, the raw material is placed on the processing table 1 through the arc groove on the support plate 36. At this time, the right end of the raw material is in contact with the left side of the fixed-length plate 94. The electric push rod 7 is opened, and the telescopic shaft of the electric push rod 7 drives the moving plate 6 to move towards each other along the groove 5, causing the cutting disc 84 to move downward. The movement of the moving plate 6... The connecting plate 31 drives the pressure plate 34 to move downwards. When the cutting disc 84 moves to the appropriate position, if the pressure plate 34 and the support plate 36 have not yet fixed the raw material, the rotating disc 352 drives the screw 351 to rotate. Under the restriction of the slider 32 and the limit rod 33, the rotation of the screw 351 drives the pressure plate 34 to move downwards until the upper and lower elastic pads 38 clamp and fix the raw material. Due to the presence of the anti-slip protrusions 37, the friction is increased, preventing the raw material from sliding. After the raw material is fixed, the motor 85 is turned on, and the output shaft of the motor 85 drives the rotating disc to move downwards. When the cutting disc 84 rotates, the second motor 86 is turned on. The output shaft of the second motor 86 drives the lead screw 82 to rotate. The rotation of the lead screw 82 causes the threaded slider 83 to slide along the slide groove 81, causing the rotating cutting disc 84 to move along the slide groove 81 to cut the fixed raw material. After the cutting is completed, the moving plate 6 is moved upward by the electric push rod 7, causing the pressure plate 34 to move upward to release the fixation of the raw material. When cutting the same type of raw material again, it is not necessary to adjust it through the adjustment component 35 to fix the raw material.

[0027] It is worth noting that the microcontroller 2 disclosed in the above embodiments can be an STM32F1, the motor 1 85, the motor 2 86 and the motor 3 96 can be YP-100 series, the laser rangefinder 95 can be KCW212X series, and the microcontroller 2 controls the operation of the electric push rod 7, the motor 1 85, the motor 2 86, the laser rangefinder 95 and the motor 3 96 using methods commonly used in the prior art.
