Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of metal material manufacturing, more particularly, to a metal plate punching machine for plug processing. BACKGROUND

[0002] The plug metal plate is an important component of the plug, also known as the pin, which is usually used to insert into the metal hole of the electrical socket to ensure the smooth connection between the electrical appliance and the power supply. The pin is generally made of metal materials with good electrical conductivity, such as copper, copper alloy, stainless steel or aluminum, etc. The selection of these metal materials directly affects the performance and reliability of the connector. Copper is a material with excellent dielectric properties, good electrical conductivity and thermal conductivity, and is a popular choice for manufacturing connector pins and sockets. Copper alloy can improve mechanical properties and corrosion resistance. Stainless steel can provide additional durability and reliability, and aluminum is a lightweight material with good electrical conductivity.

[0003] Punching is a process for manufacturing pins, which is to apply external force to the metal plate through a press and a die to produce plastic deformation, thereby obtaining a workpiece with the required shape and size. In the pin punching process, various punching processes may be required, such as punching, blanking, bending, etc., to meet the requirements of complex shape, small size and high precision of the pin. In order to improve production efficiency and precision, a progressive die compound process is usually selected for punching. The progressive die can complete all the punching processes required for the production of pins with complex shape, small size and high precision, such as blanking, bending, deep drawing and three-dimensional forming, etc.

[0004] In the prior art, after the plug metal plate is punched, it needs to be cut by a cutter to complete the manufacturing of the pin. During the cutting process of the metal plate by the cutter, the surface layer of the workpiece undergoes stress, heat and deformation, and the metallographic structure changes greatly, resulting in some small metal fragments or impurities adhering to the surface of the cutter. At the same time, the work hardening phenomenon makes the surface of the cutter become harder and rougher, which makes it more likely to adsorb metal impurities, resulting in a decrease in the cutting effect of the cutter on the metal plate.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Please refer to Figures 1 to 8The utility model provides a metal plate punch press for plug processing, including body 1 and the hydraulic pressure ware 11 of setting in the vertical part inside body 1, and the telescopic end of hydraulic pressure ware 11 is provided with work die 12, and the upper side of the horizontal part of body 1 is provided with female die 13, and the outside of work die 12 is equipped with maintenance parts 2;

[0034] Maintenance parts 2 include movable sleeve 21 that is sleeved on the outside of work die 12, the lower side of movable sleeve 21 is detachably installed with bottom plate 22, the left and right sides of the upper end of bottom plate 22 are both fixedly connected with first pressure spring 23 in parallel, the front and back sides of the left and right ends in movable sleeve 21 are both provided with sliding slot 24, the front and back sides of the left and right ends of work die 12 are both fixedly connected with sliding block 25, sliding block 25 is slidably connected in sliding slot 24, cutting tool 26 is installed on the lower side of work die 12, cutting tool 26 penetrates bottom plate 22, the left and right sides of the inner surface of bottom plate 22 are both fixedly connected with wiping cotton 27, and the opposite surface of wiping cotton 27 is slidably contacted with the left and right sides of cutting tool 26.

[0035] The right side of the center of bottom plate 22 is hollowly provided, and is matched with the shape of wiping cotton 27, and cutting tool 26 is exposed from the inside of bottom plate 22 after the movement of bottom plate 22.

[0036] By adopting the above technical solution, after the raw material is placed inside the master mold 13, the hydraulic device 11 equipped inside the machine body 1 can be activated to push the die 12 downward. The die 12 first contacts the raw material. Because the outside of the die 12 is connected to the slide groove 24 through the slider 25, the movable sleeve 21 is restricted to the outside of the die 12. At the same time, the bottom plate 22 under the movable sleeve 21 can also slide up and down on the outside of the die 12. As the die 12 continues to press the raw material, the bottom plate 22 contacts the master mold 13. At this time, the sliding bottom plate 22 will push the movable sleeve 21 upward, so that the first pressure spring 23 between the movable sleeve 21 and the die 12 is squeezed inside the movable sleeve 21. At this time, the cutting tool 26 will gradually be exposed from the inside of the bottom plate 22 until the upper side of the movable sleeve 21 contacts the outer surface of the die 12. The movable sleeve 21 stops moving, and as the hydraulic device 11 squeezes the die 12, the cutting tool 26 will cut the pressed raw material. When the material is being cut, and the hydraulic device 11 pulls the die 12 upward, the first pressure spring 23 continuously pushes the movable sleeve 21, causing the lower side of the base plate 22 to fit tightly against the upper side of the mother die 13. Then, the base plate 22 re-wraps the cutting tool 26, and the die 12 pulls the movable sleeve 21 and the base plate 22 upward. During the process of the base plate 22 re-wrapping the cutting tool 26, the wiping cotton 27 inside the base plate 22 wipes both sides of the cutting tool 26 as it passes over the base plate 22. Since the cutting tool 26 passes through the wiping cotton 27 repeatedly during operation, if metal impurities are attached to the surface of the cutting tool 26, the wiping cotton 27 will promptly remove the metal impurities, effectively preventing the cutting effect from being reduced due to the attachment of metal impurities. At the same time, the wiping cotton 27 can also effectively reduce the heat on the surface of the cutting tool 26, preventing the metal impurities from being accelerated to adhere to the surface of the cutting tool 26 due to changes in the metallographic structure.

[0037] like Figures 5 to 8 As shown, the inner and outer sides of the mold 12 are provided with a liquid injection assembly 28, which includes a first piston rod 281 fixedly connected to the upper side of the base plate 22.

[0038] A first piston chamber 282 is provided through the lower side of the interior of the mold 12. A first piston rod 281 is slidably connected in the first piston chamber 282. A guide groove 283 is provided on the left side of the upper end of the first piston chamber 282. A storage chamber 284 is provided inside the mold 12. The first piston chamber 282 is connected to the storage chamber 284 through the guide groove 283. Baffles 285 are fixedly connected to the upper and lower sides of the left and right ends of the storage chamber 284. A movable plate 286 is slidably connected inside the storage chamber 284. After the movable plate 286 moves, it presses against the baffles 285. Nozzles 287 are arranged in parallel on the lower side of the interior of the storage chamber 284 and penetrate through the lower side of the mold 12.

[0039] The lower side of the working mold 12 is fixedly connected with a protective frame 288, which surrounds the outside of the cutting tool 26. The upper side of the bottom plate 22 is provided with an embedding groove 289. The protective frame 288 is slidably connected in the embedding groove 289 after moving downward. The working mold 12 is in extrusion contact with the wiping cotton 27 after moving downward. The left and right symmetrical spray heads 287 are located on the left and right sides of the cutting tool 26. The shape of the movable plate 286 is adapted to the shape of the storage cavity 284.

[0040] By adopting the above technical scheme, when the lower side of the bottom plate 22 is in contact with the female mold 13, the first piston rod 281 above the bottom plate 22 moves relative to the first piston cavity 282 inside the working mold 12, and the gas inside the first piston cavity 282 is compressed. The compressed gas will enter the storage cavity 284 through the guide groove 283 and always be above the movable plate 286. When the movable plate 286 moves up and down in the storage cavity 284, it is limited by the baffle 285, so that the moving range of the movable plate 286 is limited. When the compressed gas reaches above the movable plate 286, the gas will extrude the movable plate 286, so that the movable plate 286 starts to move downward. If there is cooling liquid below the movable plate 286, the cooling liquid will be sprayed out through the spray head 287 under the extrusion of the movable plate 286 and sprayed to the wiping cotton 27. During the gradual adhesion of the bottom plate 22 and the working mold 12, the protective frame 288 below the working mold 12 will be connected with the embedding groove 289 above the bottom plate 22, so that the cooling liquid sprayed by the spray head 287 is always within the wrapping range of the protective frame 288. Since the wiping cotton 27 is wetted by the cooling liquid sprayed by the spray head 287 during wiping of the cutting tool 26, the wiping cotton 27 not only can remove the metal impurities attached to the surface of the cutting tool 26, but also the cutting blade extrudes the wiping cotton 27, so that the cooling liquid absorbed by the wiping cotton 27 is immersed in the surface of the cutting tool 26, further improving the cooling effect of the cutting tool 26.

[0041] As shown in Figures 6 to 8 The inside of the working mold 12 is provided with a supplement assembly 29. The supplement assembly 29 includes a guide pipe 291 which is arranged through the back side of the storage cavity 284.

[0042] The other end of the guide pipe 291 is connected with an external liquid supply device. The upper side of the movable plate 286 is fixedly connected with a limiting rod 292. The inside of the upper side of the storage cavity 284 is provided with a limiting groove 293. The limiting rod 292 is slidably connected in the limiting groove 293. The inside of the upper side of the limiting groove 293 is provided with a laser range finder 294. The front side of the machine body 1 is provided with a controller 295.

[0043] By adopting the above technical scheme, during the up and down movement of the movable plate 286, the limiting rod 292 fixed above the movable plate 286 will move up and down inside the limiting groove 293, and in this process, the laser range finder 294 on the upper side inside the limiting groove 293 detects the limiting rod 292 in real time, then the laser range finder 294 transmits information to the controller 295, and then the controller 295 controls the external liquid supply equipment connected at the other end of the conduit 291 according to the preset maximum value and minimum value, when the data detected by the laser range finder 294 is the maximum value, the external liquid supply equipment stops running, and when the data detected by the laser range finder 294 is the minimum value, the external liquid supply equipment starts running. Since the laser range finder 294 detects the position of the limiting rod 292 in real time, the amount of cooling liquid in the storage cavity 284 can be calculated in real time, and the external liquid supply equipment can be controlled to start and stop in time when the cooling liquid is transported, and sufficient cooling liquid can guarantee the cooling efficiency of the cutting tool 26.

[0044] As shown in Figure 2 and Figure 4 , the inner and outer sides of the female mold 13 are jointly provided with a collecting component 3, which includes a second piston rod 31 fixedly connected to the left and right sides of the front and rear ends of the working mold 12.

[0045] The upper end of the female mold 13 is arranged in a rectangular array and is provided with a second piston cavity 32, the second piston rod 31 is slidingly connected in the second piston cavity 32, the working mold 12 and the female mold 13 are fixedly connected with a second pressure spring 35, and the second pressure spring 35 is sleeved outside the second piston rod 31.

[0046] The inner wall of the second piston cavity 32 is provided with a through hole 33, the inside of the female mold 13 is provided with a collecting cavity 34, and the second piston cavity 32 is communicated with the collecting cavity 34 through the through hole 33.

[0047] By adopting the above technical scheme, when the working die 12 moves downward, because the second piston rods 31 on the front and back sides of the working die 12 extend to the second piston cavities 32 above the female die 13, the second piston rods 31 will compress the air inside the second piston cavities 32 after moving downward, at the same time, the working die 12 will press the second pressure springs 35, and after the air inside the second piston cavities 32 is pressed, the air will enter the collecting cavities 34 inside through the through holes 33, at this time, the working die 12 will also stamp the raw material, and the raw material will shield the inlet through which the female die 13 conveys the waste material, at the same time, the compressed air inside the collecting cavities 34 will also flow to the lower side of the raw material, and cooperate with the working die 12 to press the raw material, when the working die 12 moves upward, the second piston rods 31 move upward inside the second movable grooves, so that the air pressure inside the second piston cavities 32 and the collecting cavities 34 changes, causing the flowing air to attract the waste material, so that the waste material accelerates to enter the inside of the collecting cavities 34, because the working die 12 stamps the raw material, the second piston rods 31 adjust the air pressure inside the collecting cavities 34, on the one hand, the raw material is pressed, so that the raw material closely adheres to the working die 12 during the stamping process, on the other hand, the waste chips generated during the stamping process are extracted, so as to accelerate the collection of the waste chips.

[0048] Working principle: the hydraulic device 11 equipped inside the machine body 1 pushes the working die 12 downward, the working die 12 first contacts the raw material, because the working die 12 is connected with the sliding groove 24 through the sliding block 25, so that the movable sleeve 21 can move up and down on the outside of the working die 12, with the working die 12 continues to punch the raw material, the bottom plate 22 contacts the female die 13, so that the movable sleeve 21 extrudes the first pressure spring 23, and the cutting tool 26 is gradually exposed from the inside of the bottom plate 22, then the raw material after punching is cut, when the hydraulic device 11 pulls the working die 12 upward, the bottom plate 22 rewraps the cutting tool 26, the wiping cotton 27 in the bottom plate 22 wipes the two sides of the cutting tool 26 when the cutting tool 26 passes through the bottom plate 22, at the same time, the first piston rod 281 above the bottom plate 22 moves in the first piston cavity 282, and the gas in the first piston cavity 282 is compressed, the gas enters the storage cavity 284 through the guide groove 283, when the compressed gas reaches above the movable plate 286, the gas will extrude the movable plate 286, if there is cooling liquid below the movable plate 286, the cooling liquid will be sprayed out through the nozzle 287 under the extrusion of the movable plate 286 and sprayed to the wiping cotton 27, and in the process that the bottom plate 22 gradually fits with the working die 12, the protective frame 288 below the working die 12 will be connected with the embedded groove 289 above the bottom plate 22, so that the cooling liquid sprayed by the nozzle 287 is always within the wrapping range of the protective frame 288, in the process that the movable plate 286 moves up and down, the limiting rod 292 fixed above the movable plate 286 moves up and down in the limiting groove 293, in this process, the laser range finder 294 inside the limiting groove 293 detects the limiting rod 292 in real time, then the laser range finder 294 transmits the information to the controller 295, and according to the preset maximum value and minimum value, the external liquid supply equipment connected with the other end of the guide pipe 291 is controlled to open and close, after the working die 12 moves downward, the second piston rod 31 compresses the air in the second piston cavity 32, so that the air enters the collecting cavity 34 through the through hole 33, at this time, the working die 12 also punches the raw material, and the raw material shields the inlet of the female die 13 for conveying waste materials, at the same time, the compressed air in the collecting cavity 34 also flows below the raw material and cooperates with the working die 12 to press the raw material, when the working die 12 moves upward, the second piston rod 31 moves upward in the second moving groove, so that the air pressure in the second piston cavity 32 and the collecting cavity 34 changes, causing the flowing air to attract the waste materials, so that the waste materials accelerate into the collecting cavity 34.

[0049] The above merely shows a preferred embodiment of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art, according to the technical solution and improvement concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
