Description

Technical Field

[0001] This utility model relates to the field of crimping blade technology, specifically a piercing integrated crimping blade. Background Technology

[0002] A piercing and crimping blade is a tool specifically designed for piercing and crimping materials. It is widely used in production lines in the electronics, electrical appliances, and automotive industries. Its working principle mainly relies on the high-speed rotation of the blade and its sharp edge to quickly pierce the surface of the material. Then, pressure is used to tightly crimp the material to another component. Traditional crimping blades are mostly bolted to the crimping machine, making disassembly and assembly inconvenient when the blade needs to be replaced. To improve this situation, an integrated piercing and crimping blade has been proposed.

[0003] For example, a crimping blade disclosed in authorization announcement number CN209993858U includes a blade body, a mounting hole, and a guide groove. The mounting hole and guide groove are provided on the blade body. The blade body is composed of a connecting blade head and a crimping blade head. The connecting blade head is provided with a plurality of positioning bosses, which are matched and connected with the crimping blade head. The side of the positioning boss is provided with a first pin hole, and the side of the crimping blade head is provided with a second pin hole. The crimping blade head is provided with a pair of opening grooves. The opening of the opening groove is provided with a flared mouth, and the bottom of the opening groove is provided with a pair of arc surfaces.

[0004] Although it achieves the ability to directly start the machine by simply replacing the crimping head when changing the blade, without having to replace the whole machine and then adjust it, the bottom of the opening slot has a pair of arc surfaces. The junction of the arc surfaces provides better clamping force on the one hand, and more squeezing space on the other hand, which avoids the terminals being crushed and improves the yield rate.

[0005] However, this does not solve the problem that existing crimping blades are not convenient for quick and easy insertion, removal, and replacement, nor for elastically ejecting the wire harness, thus affecting the convenience of blade replacement and wire harness output. Utility Model Content

[0006] The purpose of this invention is to provide a piercing integrated crimping blade to solve the problems mentioned in the background art, such as the inconvenience of quick and easy insertion, disassembly and replacement of the crimping blade, the difficulty in elastically kicking out the wire harness, and the impact on the convenience of blade replacement and wire harness output.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a piercing integrated crimping blade, comprising a blade body and blades, wherein two sets of blades are provided at the bottom end of the blade body and are fixedly connected to the blade body, and two sets of sliding rods are fixedly installed between the two sets of blades; connecting blocks are symmetrically arranged on the side wall of the blade body and are fixedly connected to the blade body; each side wall of the connecting block is provided with a limiting post and is fixedly connected to the connecting block; an insertion seat is provided outside the limiting post and is slidably connected to the limiting post; a limiting groove is provided on the surface of the limiting post; and limiting rings are symmetrically arranged on the side wall of the insertion seat and are fixedly connected to the insertion seat.

[0008] Preferably, each of the limiting rings has a plug-in post inside, and the plug-in post is slidably connected to the limiting ring.

[0009] Preferably, each of the plug-in posts is fitted with a limit spring, and the two ends of the limit spring are fixedly connected to the limit ring and the plug-in post, respectively.

[0010] Preferably, the plug can be inserted into the interior of the limiting groove, and the plug is slidably connected to the limiting groove.

[0011] Preferably, the surface of each slide bar is provided with a kick spring, and the top of the kick spring is connected to the blade.

[0012] Preferably, a sliding plate is provided on the outside of the slide rod, and the sliding plate is slidably connected to the slide rod, and the sliding plate is connected to the bottom end of the kick spring.

[0013] Preferably, a connecting rod is provided at the bottom end of the sliding plate, and the connecting rod is fixedly connected to the sliding plate.

[0014] Preferably, a baffle is provided at the bottom end of the connecting rod, and the baffle is fixedly connected to the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the crimping blade not only realizes convenient and quick insertion, disassembly and replacement of the blade, and facilitates the elastic kicking out of the wire harness, but also improves the convenience of blade replacement and wire harness output.

[0016] (1) Fix the connector to the frame of the crimping machine. When the blade needs to be disassembled and replaced after long-term use, pull the connector. The connector slides inside the limit ring, and the connector squeezes the limit spring and pulls the connector out of the limit groove, so that the connector moves away from the limit post. Then take the blade, and the blade moves the connecting block, which in turn moves the limit post, so that the limit post moves out of the connector. Then replace the blade with a new one. After replacement, insert the limit post into the connector. With the sliding engagement, the limiting post drives the insertion post to move outward and the insertion post squeezes the limiting spring. When the limiting groove moves to the position of the insertion post, the limiting spring drives the insertion post to slide inside the limiting ring and insert the insertion post into the inside of the limiting groove. Two sets of insertion posts limit the limiting post, thereby fixing the limiting post inside the insertion seat. This, in turn, fixes the connecting block and the blade body on the insertion seat, enabling quick disassembly and replacement of the blade body. This achieves convenient and quick insertion, disassembly, and replacement of the blade, improving the convenience of blade replacement.

[0017] (2) The crimping machine drives the blade and the cutting edge to move downwards. Because the cutting edge of the cutting edge is designed with an inner arc shape, the wire harness is broken on both sides under the squeezing action of the cutting edge. At the same time, the wire harness moves upwards during the squeezing process. The wire harness drives the baffle to move. The baffle drives the sliding plate to slide on the surface of the sliding rod through the connecting rod. The sliding plate squeezes the kick spring. After the crimping is completed, the crimping machine drives the blade and the cutting edge to move upwards. The kick spring drives the sliding plate to move downwards. The sliding plate drives the baffle to move downwards through the connecting rod. The baffle drives the wire harness to separate from the cutting edge, so as to prevent the wire harness from getting stuck inside the cutting edge. This facilitates the rapid discharge of the wire harness and realizes the convenient elastic linkage to kick out the wire harness, preventing the wire harness from getting stuck inside the cutting edge and improving the convenience of wire harness output.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6 An embodiment of this utility model provides: a piercing integrated crimping blade, including a blade body 1 and blade 2. Two sets of blades 2 are provided at the bottom end of the blade body 1 and are fixedly connected to the blade body 1. Two sets of sliding rods 5 are fixedly installed between the two sets of blades 2. Connecting blocks 3 are symmetrically arranged on the side wall of the blade body 1 and are fixedly connected to the blade body 1. Limiting posts 7 are provided on the side wall of each connecting block 3 and are fixedly connected to the connecting block 3. Insertion seats 4 are provided outside the limiting posts 7 and are slidably connected to the limiting posts 7. Limiting grooves 14 are provided on the surface of the limiting posts 7. Limiting rings 12 are symmetrically arranged on the side wall of the insertion seats 4 and are fixedly connected to the insertion seats 4.

[0027] The connector 4 is fixedly connected to the frame of the crimping machine. When the blade 1 needs to be disassembled and replaced after prolonged use, the connector 6 is pulled out. The connector 6 slides inside the limiting ring 12, pressing the limiting spring 13 and pulling it out of the limiting groove 14, thus moving the connector 6 away from the limiting post 7. Then, the blade 1 is removed, causing the connecting block 3 to move, which in turn moves the limiting post 7, moving it out of the connector 4. A new blade 1 is then installed. After replacement, the limiting post 7 is inserted into the connector 4. Under the sliding cooperation of the limiting post 7 and the connector 6, the blade 1... The limiting post 7 drives the insertion post 6 to move outward and the insertion post 6 presses the limiting spring 13. When the limiting groove 14 moves to the position of the insertion post 6, under the elastic action of the limiting spring 13, the limiting spring 13 drives the insertion post 6 to slide inside the limiting ring 12 and insert the insertion post 6 into the inside of the limiting groove 14. The two sets of insertion posts 6 limit the limiting post 7, thereby fixing the limiting post 7 inside the insertion seat 4, and then fixing the connecting block 3 and the blade 1 on the insertion seat 4, so as to complete the quick disassembly and replacement of the blade 1, realizing convenient and quick insertion, disassembly and replacement of the blade, and improving the convenience of blade replacement.

[0028] Each limiting ring 12 is provided with a plug post 6 inside, and the plug post 6 is slidably connected to the limiting ring 12;

[0029] Each of the plug-in pins 6 is fitted with a limit spring 13, and the two ends of the limit spring 13 are fixedly connected to the limit ring 12 and the plug-in pin 6 respectively. The plug-in pin 6 can be inserted into the interior of the limit groove 14, and the plug-in pin 6 is slidably connected to the limit groove 14.

[0030] The surface of the slide bar 5 is provided with kicking springs 11, and the top of the kicking springs 11 is connected to the blade 1. The outside of the slide bar 5 is provided with a sliding plate 8, and the sliding plate 8 is slidably connected to the slide bar 5, and the sliding plate 8 is connected to the bottom of the kicking springs 11.

[0031] A connecting rod 9 is provided at the bottom end of the sliding plate 8, and the connecting rod 9 is fixedly connected to the sliding plate 8. A baffle 10 is provided at the bottom end of the connecting rod 9, and the baffle 10 is fixedly connected to the connecting rod 9.

[0032] The crimping machine moves the blade 1 and blade 2 downwards. Because the blade 2 has an inwardly curved design at the cutting edge, the pressure from the blade breaks the insulation on both sides of the wire harness. Simultaneously, the wire harness moves upwards during the crimping process, causing the baffle 10 to move. The baffle 10, through the connecting rod 9, causes the sliding plate 8 to slide on the surface of the sliding rod 5. The sliding plate 8 then presses against the kick spring 11. After crimping, the crimping machine moves the blade 1 and blade 2 upwards. With the elastic cooperation of the kick spring 11, the kick spring 11 causes the sliding plate 8 to move downwards. The sliding plate 8, through the connecting rod 9, causes the baffle 10 to move downwards. The baffle 10 then causes the wire harness to detach from the blade 2, preventing the wire harness from getting stuck inside the blade 2. This facilitates the rapid discharge of the wire harness, achieving convenient elastic linkage to kick the wire harness out and preventing it from getting stuck inside the blade, thus improving the convenience of wire harness output.

[0033] Working principle: The connector 4 is fixedly connected to the frame of the crimping machine. When the blade 1 needs to be disassembled and replaced after long-term use, the connector 6 is pulled out. The connector 6 slides inside the limiting ring 12, and the connector 6 compresses the limiting spring 13, causing the connector 6 to be pulled out of the limiting groove 14, thus moving the connector 6 away from the limiting post 7. Then, the blade 1 is removed, and the blade 1 drives the connecting block 3 to move. The connecting block 3 drives the limiting post 7 to move, thus moving the limiting post 7 out of the connector 4. After replacing the blade 1, insert the limiting post 7 into the insertion socket 4. Under the sliding engagement of the limiting post 7 and the insertion post 6, the limiting post 7 drives the insertion post 6 to move outwards, and the insertion post 6 presses against the limiting spring 13. When the limiting groove 14 moves to the position of the insertion post 6, under the elastic action of the limiting spring 13, the limiting spring 13 drives the insertion post 6 to slide inside the limiting ring 12 and insert the insertion post 6 into the limiting groove 14. The two sets of insertion posts 6 then engage the limiting post 7. The limit switch is used to fix the limit post 7 inside the connector 4, thereby fixing the connecting block 3 and the blade 1 on the connector 4, so as to quickly disassemble and replace the blade 1. The crimping machine drives the blade 1 and the blade 2 to move downward. Because the blade 2 has an inward arc design at the cutting edge, the insulation on both sides of the wire harness is broken under the pressure of the blade. At the same time, the wire harness moves upward during the crimping process, which drives the baffle 10 to move. The baffle 10 drives the sliding plate 8 through the connecting rod 9 on the sliding rod 5. The surface slides, and the sliding plate 8 presses the kick spring 11. After the crimping is completed, the crimping machine drives the blade body 1 and the blade 2 to move upward. Under the elastic cooperation of the kick spring 11, the kick spring 11 drives the sliding plate 8 to move downward. The sliding plate 8 drives the baffle 10 to move downward through the connecting rod 9. The baffle 10 drives the wire harness to disengage from the blade 2 to prevent the wire harness from getting stuck inside the blade 2, which facilitates the rapid discharge of the wire harness. The above is the complete usage of the piercing integrated crimping blade.
