[0002] A crimping machine is a device used to connect cables or wires. It is widely used in the electronics, electrical and communications industries. It uses mechanical pressure to crimp metal connectors (such as connectors, terminals, etc.) onto cables or wires to achieve electrical connections.

[0003] In order to facilitate the connection of wires to terminals, it is necessary to use a stripping and crimping machine to strip and crimp the wires. For example, the prior art Chinese patent announcement number "CN208357944U" discloses a servo stripping machine blade crimping structure, including a stripping screw module and a cutting knife module. The stripping screw module is a horizontally placed semi-enclosed screw linear slide, and a stepping motor is provided at one end of the stripping screw module. A cutting knife module is longitudinally provided on the stripping screw module; the rear end of the clamping arm of the utility model is guided and positioned by a double guide rod and a double shaft sleeve, and the front end of the clamping arm slides with the slide rail through a slider, effectively reducing the wear between the screw and the screw nut, improving the stability of the clamping arm running towards each other, and improving the stripping quality of the stripping machine; the cutting blade is installed and positioned through the positioning groove of the blade seat, and is fixedly installed through the mounting waist hole and the mounting hole, which facilitates the longitudinal adjustment of the cutting blade and reduces the reduction in efficiency and quality caused by the inability to adjust the blade due to wear of the cutting blade.

[0004] However, in actual operation, considering that the cutting blade and the knife holder are fixed by a locking bolt, it is not convenient to replace them after long-term use and wear, which affects the wire stripping efficiency. In addition, wires of different diameters require blades of different sizes and shapes to adapt. Thicker wires may require larger and stronger blades for stripping. Because the knife holder and the cutting blade do not match, they need to be replaced together with the knife holder. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as the inconvenience in replacing the cutting blade and the inability to replace the blade holder, which leads to the mismatch between the blade and the wire, and to propose a stripping and crimping machine.

[0024] The peeling member 5 includes a cutting blade 51 and a blade holder 52 , and the cutting blade 51 and the blade holder 52 are fixed by a fixing member 6 .

[0025] It should be added that the crimping device 2 includes a base fixed on the table of the housing 1, a cylinder is fixedly mounted on the base through a bracket, and crimping dies are respectively fixed on the top of the base and the end of the cylinder shaft. Under the drive of the cylinder, the wire and the terminal are crimped by a pair of crimping dies;

[0026] The peeling device 3 further includes a cylinder and a slide rail. The cylinder is fixed to the top of the inner wall of the shell 1, and the pressure plate 31 is fixed to its shaft end. The other pressure plate 31 is slidably connected to the table of the shell 1 through the slide rail. The shell 1 is fixed with a motor on the table. The shaft end of the motor is fixedly connected to a screw rod, and the screw rod is threadedly connected to the connecting seat at the bottom of the pressure plate 31.

[0027] Specifically, a fixing seat needs to be fixed on the pressure plate 31 at the bottom. The fixing seat includes a pair of hinged fixing plates, which are fixed by locking bolts or buckles. The wire is passed through the stripping piece 5 and then fixed between the pair of fixing plates. The fixing seat clamps the wire and then drives the electric push rod to pull out the wire sheath.

[0028] Furthermore, the quick-release part 4 includes an end cover 41 and a base 42. The base 42 is fixed on both sides of the end surface of the pressure plate 31 below the knife seat 52. A cavity is provided in the base 42, and its top passes through the knife seat 52 to form an avoidance groove 43. A pair of card slots 421 are opened on the top of the inner wall of the cavity, and the card slots 421 and the avoidance groove 43 are arranged in a cross shape.

[0029] Furthermore, it also includes an insertion rod 44, and a accommodating cavity 45 is provided in the end cover 41. The accommodating cavity 45 is located at the opening and extends inward to form an extension portion 451. The insertion rod 44 is slidably connected to the accommodating cavity 45, and its bottom and top are respectively provided with a locking portion 441 and a protrusion 442. The locking portion 441 is engaged with the locking groove 421 through the avoidance groove 43, and the protrusion 442 contacts the extension portion 451.

[0030] In more detail, a spring 46 is provided on the outer periphery of the insertion rod 44 , and both ends of the spring 46 abut against the side surfaces of the accommodating cavity 45 and the protrusion 442 . The insertion rod 44 is also rotatably connected to the end cover 41 .

[0031] It is worth mentioning that the quick release member 4 specifically refers to the thumb lock structure in the prior art;

[0032] Specifically, the insertion rod 44 is pressed to allow the locking portion 441 to pass through the avoidance groove 43 and be located in the cavity. Then, the insertion rod 44 is rotated to allow the locking portion 441 to deviate from the avoidance groove 43 and align with the locking groove 421. Under the elastic support of the spring 46, the insertion rod 44 moves upward and the locking portion 441 is fixed in the locking groove 421, thereby achieving the purpose of fixing the knife holder 52 and the pressure plate 31.

[0033] The advantage of this is that in the prior art, the knife holder 52 is mostly fixed by a locking bolt, and the knife holder 52 can be easily replaced by the quick release part 4, so that the knife holder 52 can carry the appropriate cutting blade 51 to process wires of different diameters and materials, thereby preventing the wire from being incompatible with the cutting blade 51 and the knife holder 52 from being incompatible with the larger and thicker cutting blade 51.

[0034] In general, the side surface of the knife seat 52 is recessed inward to form a plurality of recessed grooves 521 , and both sides of the recessed grooves 521 extend toward both sides to form slots 522 , through which the cutting blade 51 is plugged into the knife seat 52 .

[0035] Finally, the fixing member 6 is a positioning glass bead 61 , which is embedded in the side of the recessed groove 521 , and the cutting blade 51 is engaged with the positioning glass bead 61 through an insertion hole.

[0036] Specifically, the cutting blade 51 is located at the top and is recessed inward to form a cutting groove. The cutting blades 51 on both sides are correspondingly arranged. By closing together, the outer skin of the wire is cut off by the cutting groove to perform the stripping operation on the wire.

[0037] Working method: When working, the knife seat 52 is replaced according to the material and diameter of the wire, and the insertion rod 44 is pressed to make the locking portion 441 pass through the avoidance groove 43 and be set in the cavity. Then, the insertion rod 44 is rotated to make the locking portion 441 deviate from the avoidance groove 43 and align with the locking groove 421. Under the elastic support of the spring 46, the insertion rod 44 moves upward and the locking portion 441 is fixed in the locking groove 421, thereby replacing and fixing the knife seat 52 and the pressure plate 31.

[0038] After the cutting blade 51 has been used for a long time, the positioning glass bead 61 is pressed to retract it, and the cutting blade 51 is pulled out and replaced with a new one, and then inserted along the slot 522 and fixed by engaging with the positioning glass bead 61;

[0039] After the motor drives the bottom pressure plate 31 to move to the appropriate position, the cylinder drives the top pressure plate 31 to move, and the pressure plates 31 on both sides close to use a pair of cutting blades 51 to cut the outer skin of the wire. Then the electric push rod drives the fixed seat to move to pull out the outer skin, and finally the wire is moved to a pair of crimping dies for terminal crimping.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
