Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of terminal crimping machines, in particular to a terminal wire rear end cutting and stripping device. Background Art
[0002] A terminal crimping machine is a combination of equipment used to crimp wires and insert rubber casings. It involves multiple processes, including wire feeding, cutting, stripping, tinning, crimping, and inserting the rubber casing. After the wire is cut to length and before tinning, the rubber casing at both ends of the wire must be cut and stripped to expose the fiber core. However, existing terminal crimping machines typically have separate cutting and stripping mechanisms. After the cut wire segments are formed, the front and back ends must be stripped separately, requiring the wire to undergo two stripping steps, which is time-consuming and inefficient. This led the inventors to develop a new invention. Utility Model Content

Two cutting components 5, the first cutting component 4 and the second cutting component 5 are both provided with a positioning plate 41, a cutting knife 42, and a peeling knife 43 arranged in sequence, wherein the cutting knife 42 and the peeling knife 43 are both V-shaped cutters, the blade height of the cutting knife 42 is higher than the blade height of the peeling knife 43, and a material guide tube 51 is provided below the second cutting component 5, and a second motor 14 is provided on the mounting plate 1, and the second motor 14 is provided with a rotating rod 15, and the rotating rod 15 is provided with a first threaded portion 151 and a second threaded portion 152 connected to the first threaded sleeve 121 and the second threaded sleeve 131 respectively, the first threaded portion 151 and the second threaded portion 152 have opposite thread directions, and when the rotating rod 15 rotates forward or reverse, the first threaded sleeve 121 and the second threaded sleeve 131 approach or move away from each other, thereby making the first cutting component 4 and the second cutting component 5 movable. In the solution of the present utility model, other equipment on the terminal crimping machine equipment transports the wire to between the first cutting component 4 and the second cutting component 5, the wire grabber 3 grabs the wire, and the second motor 14 drives the rotating rod 15 to rotate, so that the first cutting component 4 and the second cutting component 5 are close to each other. During the action of the first cutting component 4 and the second cutting component 5, the positioning plate 41 fixes the wire, the cutting knife 42 cuts the wire, and the stripping knife 43 cuts the rubber of the wire grabbed by the wire grabber 3. Then the first motor 24 drives the wire grabber 3 to move, and the wire grabber 3 pulls the rear end of the wire out from between the first cutting component 4 and the second cutting component 5. The rubber cut by the stripping knife 43 at the rear end of the wire will be peeled off by the stripping knife 43, and the peeled rubber will eventually be discharged through the guide tube 51. Through the cooperation of the first cutting component 4, the second cutting component 5 and the wire grabber 3, the wire can be stripped while being cut, thereby improving the efficiency of the stripping process before the wire is crimped.
[0025] The connecting plate 23 is provided with a third threaded sleeve 25, and the first motor 24 is provided with a screw 26 connected to the third threaded sleeve 25. The first motor 24 drives the thread grabber 3 to perform a short-range movement. Through the connection between the screw 26 and the third threaded sleeve 25, the rotational kinetic energy of the first motor 24 is converted into linear kinetic energy, thereby increasing the thread pulling force of the thread grabber 3.
[0026] The wire grabber 3 is equipped with a cylinder 31. Below the cylinder 31 are two fixed plates 32 fixed to the housing of the cylinder 31. Between the two fixed plates 32 are two symmetrical sets of curved arms 33. The two sets of curved arms 33 are symmetrical. The protruding end of the cylinder 31 is provided with a push block 34 movably connected to the curved arms 33. When the cylinder 31 drives the push block 34 out, the push block 34 drives the curved arms 33 to swing, causing the wire grabber 3 to open. Conversely, the push block 34 can drive the curved arms 33 to swing in the opposite direction. The two sets of curved arms 33 can cooperate with each other to grab the wire, and the wire grabbing speed is fast.
[0027] Specifically, a wire clamp 35 is provided at one end of the curved arm 33, and a wire groove 36 for securing the wire is provided in the middle of the wire clamp 35. In this embodiment, the wire clamp 35 is in a sideways V-shape. When the two wire clamps 35 approach each other to grasp the wire, the upper and lower inclined surfaces of the wire clamps 35 are used to guide the wire, so that the wire falls accurately into the wire groove 36. The wire grooves 36 of the two wire clamps 35 clamp the wire, securing it, and the wire grabber 3 completes the wire grasping action, with high wire grasping accuracy.
[0028] The first cutting assembly 4 is provided with a first base 44 for fixing the positioning plate 41, the cutting knife 42, and the peeling knife 43. The second cutting assembly 5 is provided with a second base 52 for fixing the positioning plate 41, the cutting knife 42, and the peeling knife 43. The first base 44 is fixedly connected to the first threaded sleeve 121, and the second base 52 is fixedly connected to the second threaded sleeve 131. The first threaded portion 151 and the second threaded portion 152 have the same pitch and opposite thread directions. When the rotating rod 15 rotates, the first cutting assembly 4 and the second cutting assembly 5 move toward or away from each other at the same speed, resulting in high structural stability.
[0029] The second base 52 is provided with a through-hole 53 that communicates with the guide tube 51. The guide tube 51 is a flexible tube that extends into a container for storing rubber waste. Rubber waste stripped from the wire enters the guide tube 51 through the through-hole 53 and is discharged from the guide tube 51. This prevents the rubber waste from remaining on the second base 52 or falling onto other equipment components of the crimping machine, keeping the machine clean and tidy, and improving safety and environmental protection.
[0030] The positioning plate 41 is provided with a notch 411 for fixing the wire trough 36. The notch 411 is semicircular. When the positioning plates 41 of the first cutting assembly 4 and the second cutting assembly 5 are brought close to each other, the circular hole formed by the two notches 411 can fix the wire, preventing the wire from falling off after being cut and causing the wire to be misplaced.
[0031] A coupling 16 is provided between the second motor 14 and the rotating rod 15. The coupling 16 facilitates connection to various types of rotating rods 15. In this embodiment, the second motor 14 is a servo motor. To reduce operating noise, the maximum speed of the second motor 14 is limited. If the first and second cutting assemblies 4 and 5 need to be driven at a faster speed, the rotating rod 15, first and second threaded sleeves 121 and 131 can be replaced with a larger pitch to meet the needs.
[0032] A set square a17 is installed at the junction of the mounting plate 1 and the top plate 2, and a set square b18 is installed at the bottom of the mounting plate 1. Set square a17 is located at the L-shaped angle between the mounting plate 1 and the top plate 2, supporting the top plate 2 and preventing it from tilting. When the mounting plate 1 is installed behind the terminal punching machine, set square b18 can abut against the machine body, improving the stability of the mounting plate 1 after installation.
[0033] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
