Description

Technical Field

[0001] The present application relates to the field of metal electric pulse processing devices, and in particular to an electric pulse processing device for low-alloy wear-resistant steel. Background Art

[0002] Electric pulse processing is a processing method that improves the internal structure and performance of metals (such as low-alloy wear-resistant steel). It mainly uses instantaneous high-energy pulse current to process metal materials. It has the advantages of high hardness, high melting point, and difficulty in mechanical deformation. It is often used to process hard, brittle or difficult-to-process materials. Generally, after the electric pulse processing of the metal is completed, the internal structure and related properties of the metal need to be tested to ensure that the performance of the metal meets the requirements.

[0003] After searching, the Chinese patent with publication number CN206486560U discloses an electric pulse heat treatment device for low-resistance metals. The treatment device includes a heating furnace, a pair of clamping devices arranged in the heating furnace, and an electric pulse generating device electrically connected to the clamping device; the clamping device includes a first clamping block and a second clamping block, and a groove is provided on the second clamping block, and the groove matches the outer periphery of the metal to be treated. The general working principle of the treatment device is: before the metal to be treated is treated by electric pulse, the metal to be treated is fixed by the cooperation of the first clamping block and the second clamping block, which can reduce the phenomenon of metal material scattering during treatment.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following technical defects exist: when the metal to be detected is fixed by a clamping device for electric pulse treatment, the metal to be detected will undergo a volume change after being subjected to the electric pulse (the metal expands and its volume increases), and the expanded metal will have an interference fit with the first clamp block and the second clamp block (the first clamp block and the second clamp block will exert a certain reaction force on the metal to be treated), and the inside of the squeezed metal will change, thereby affecting the detection of the metal properties after the electric pulse treatment. Utility Model Content

[0005] In order to ensure the accuracy of metal detection after electric pulse treatment, the present application provides an electric pulse treatment device for low-alloy wear-resistant steel.

[0006] The present application provides an electric pulse processing device for low alloy wear-resistant steel, which adopts the following technical solution:

[0007] An electric pulse processing device for low-alloy wear-resistant steel, comprising an electric pulse generating device, a processing frame and a first clamping mechanism for clamping block-like metals; the electric pulse generating device is used to output electric pulses; the processing frame has a through hole, a chamber for storing metal and a discharge port for placing metal in the chamber, the output end of the electric pulse generating device extends into the through hole and can contact the metal to be detected; the first clamping mechanism comprises a fixed plate, a plurality of clamping blocks and a driving component; the fixed plate is arranged in the chamber of the processing frame; the clamping block is connected to the fixed plate by rotation, wherein a first clamping space for clamping the block-like metal is formed between the clamping blocks; the driving component is connected to the clamping block, and is used to drive the plurality of clamping blocks to move closer to or away from each other.

[0008] By adopting the above technical scheme, when it is necessary to perform electric pulse treatment on bulk metal, the metal to be treated is placed in the first clamping space, the driving component is adjusted, and the driving component drives multiple clamping blocks to move. The multiple clamping blocks are close to the bulk metal and clamp and fix it. After the fixation is completed, the fixing plate is sent to the feed port into the cavity of the processing frame, and the bulk metal contacts the output end of the electric pulse generating device, and the electric pulse generating device is started. The electric pulse generating device performs electric pulse treatment on the bulk metal. The volume of the bulk metal increases continuously during the electric pulse process. At this time, the clamping block rotates toward the side away from the bulk metal, reducing the reaction force exerted by the clamping block on the bulk metal, thereby reducing the squeezing of the bulk metal by the reaction force of the clamping block, and then helping to ensure the accuracy of metal detection after electric pulse treatment.

[0009] Optionally, the driving assembly includes a lifting plate and a driving member; the lifting plate is slidably connected to the fixed plate, wherein the movement direction of the lifting plate is perpendicular to the clamping direction of the metal to be detected, and the clamping block is hinged on the lifting plate; the driving member is connected to the fixed plate, and is used to drive the lifting plate to move up and down on the fixed plate.

[0010] By adopting the above technical solution, the driving member is adjusted, and the driving member drives the lifting plate to descend. The lifting plate descends on the fixed surface, and the descent of the lifting plate drives the clamping block to move, and multiple clamping blocks are close to each other, so that block metals can be clamped. Similarly, the driving member is adjusted, and the driving member drives the lifting plate to rise. The rising of the lifting plate drives multiple clamping blocks to move, so that the multiple clamping blocks are away from each other, which is convenient for removing the block metal after electric pulse treatment.

[0011] Optionally, the processing device also includes a second clamping mechanism for clamping sheet metal; the second clamping mechanism includes two clamping plates and a power assembly; the two clamping plates are slidably connected to the fixed plate through the power assembly, wherein the two clamping plates form a second clamping space for the sheet metal, and the clamping plates are arranged in the gap of the clamping block; the power assembly is used to drive the two clamping plates to move closer to or away from each other.

[0012] By adopting the above technical solution, when the sheet metal is subjected to electric pulse processing, the power component is adjusted, and the power component drives the clamping plates to approach each other, and the clamping plates contact the sheet metal, thereby achieving the purpose of fixing the sheet metal. The processing device is convenient for clamping and fixing block metals, and can also clamp and fix sheet metals, thereby improving the application scope of the processing device.

[0013] Optionally, the power assembly includes a power screw and a power turntable; the power screw is rotatably connected to the side of the fixed plate away from the clamping block; the two clamping plates are respectively connected to the positive thread segment and the negative thread segment of the power screw; and there is no interference between the power screw and the lifting plate; the power turntable is arranged on the power screw.

[0014] By adopting the above technical solution, the power turntable is adjusted and rotated, and the rotation of the power turntable drives the rotation of the power screw, and the rotation of the power screw drives the two clamping plates to move closer to each other, thereby achieving the purpose of clamping sheet metal. Similarly, the power turntable is adjusted and rotated, and the rotation of the power turntable drives the rotation of the power screw, and the rotation of the power screw drives the two clamping plates to move away from each other, thereby facilitating the removal of sheet metal after electric pulse treatment.

[0015] Optionally, a groove for accommodating sheet metal is provided on one side of the two clamping plates that are close to each other.

[0016] By adopting the above technical solution, the power screw rotates, and the power screw drives the two clamping plates to approach the sheet metal. The sheet metal extends into the groove, and the sheet metal is clamped and fixed under the continued movement of the power screw. By setting the groove on the side where the clamping plates are close to each other, it helps to improve the clamping effect of the sheet metal.

[0017] Optionally, the processing device also includes a moving mechanism for facilitating the removal of the fixed plate into the processing frame; the moving mechanism includes a plurality of moving slide rails and moving wheels; the moving slide rails are arranged on the inner wall of the processing frame, and the plurality of moving slide rails are symmetrically arranged along the movement direction of the fixed plate in the processing frame; the fixed plate slides on the moving slide rails through the moving wheels.

[0018] By adopting the above technical solution, when the metal is subjected to electric pulse treatment, the metal fixed on the fixed plate is fed into the cavity of the processing frame through the feeding port, and the moving wheel moves on the moving slide rail, thereby improving the efficiency of feeding the metal into the processing frame, thereby helping to improve the efficiency of the electric pulse treatment of the metal. Similarly, after the electric pulse treatment of the metal is completed, the fixed plate is pulled, and the fixed plate drives the moving wheel to move on the moving slide rail, which facilitates the removal of the fixed plate.

[0019] Optionally, the moving mechanism also includes a limiting screw; the limiting screw is threadedly connected to the processing frame, the limiting screw can contact the moving wheel on the side of the moving wheel close to the discharge port, and the limiting screw is used to limit the position of the fixed plate on the moving slide rail.

[0020] By adopting the above technical solution, after the fixed plate is sent to the specified position in the processing frame, the limit screw is rotated, the limit screw extends into the processing frame, and the limit screw is in contact with the moving plate, thereby achieving the purpose of fixing the fixed plate in the processing frame. At the same time, according to the limited position, it is convenient to judge whether the metal is in contact with the output end of the electric pulse generating device, thereby ensuring the stability of the metal electric pulse processing.

[0022] By adopting the above technical solution, when the fixing plate is sent into the processing frame, the baffle door is closed and the condition of the internal metal can be observed through the baffle door. At the same time, the baffle door can separate the staff from the metal of the electric pulse, reducing the occurrence of unsafe accidents.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By adjusting the driving component, the driving component drives multiple clamping blocks to move, and the multiple clamping blocks are close to the block metal and clamp and fix it. After the fixing is completed, the fixing plate is sent to the feed port into the chamber of the processing frame, and the block metal contacts the output end of the electric pulse generating device, and the electric pulse generating device is started. The electric pulse generating device performs electric pulse processing on the block metal. The volume of the block metal continues to increase during the electric pulse process. At this time, the clamping block rotates toward the side away from the block metal, reducing the reaction force exerted by the clamping block on the block metal, thereby reducing the squeezing of the block metal by the reaction force of the clamping block, which helps to ensure the accuracy of metal detection after electric pulse processing.

[0025] By adjusting the power component, the power component drives the clamping plates to move closer to each other, and the clamping plates come into contact with the sheet metal, thereby achieving the purpose of fixing the sheet metal. The processing device can be used to clamp and fix block metals as well as sheet metals, thereby improving the application range of the processing device.

[0026] By rotating the limit screw, the limit screw extends into the processing frame, and the limit screw contacts the moving plate, thereby achieving the purpose of fixing the fixed plate in the processing frame. At the same time, according to the limited position, it is convenient to judge whether the metal is in contact with the output end of the electric pulse generating device, thereby ensuring the stability of the metal electric pulse processing.

[0038] The embodiment of the present application discloses an electric pulse processing device for low alloy wear-resistant steel.

[0039] See also Figure 1 , Figure 2, an electric pulse processing device for low-alloy wear-resistant steel, used for performing electric pulse processing on metal; comprising an electric pulse generating device 1 (it should be noted that in the embodiment of the present disclosure, since two different forms of metals are processed, two electric pulse generating devices 1 are provided, and the two electric pulse generating devices 1 are independent of each other), a processing frame 2, a first clamping mechanism 3 for clamping block-like metals, a second clamping mechanism 4 for clamping plate-like metals, and a moving mechanism 5 for facilitating the placement of metals in the chamber of the processing frame 2; the electric pulse generating device 1 is used for outputting electric pulses; the processing frame 2 has a through hole 21 (not specifically marked in the drawings of the present application), a chamber for storing metals, and a discharge port 22 for placing metals in the chamber, the output end of the electric pulse generating device 1 extends into the through hole 21, and the electric pulse generating device 1 can contact the metal to be detected.

[0040] See also Figure 2 , Figure 3 The first clamping mechanism 3 includes a fixed plate 31, a plurality of clamping blocks 32, a rotating torsion spring and a driving assembly 33; the fixed plate 31 is arranged in the chamber of the processing frame 2; the clamping blocks 32 are rotatably connected to the fixed plate 31, wherein the clamping blocks 32 form a first clamping space for clamping block-like metals; the driving assembly 33 is connected to the clamping blocks 32, and is used to drive the plurality of clamping blocks 32 to move toward or away from each other. When the block-like metal on the fixed plate 31 is clamped and fixed, the driving assembly 33 drives the clamping blocks 32 to move, and the plurality of clamping blocks 32 move toward each other; the block-like metal expands under the electric pulse, and during the expansion of the metal, the clamping blocks 32 rotate to reduce the contact force between the clamping blocks 32 and the metal, so as to reduce the damage to the metal during the electric pulse treatment, which helps to improve the detection accuracy of the metal.

[0041] See also Figure 2 , Figure 3 The driving assembly 33 includes a lifting plate 331 and a driving member 332; the lifting plate 331 is slidably connected to the fixed plate 31, wherein the movement direction of the lifting plate 331 is perpendicular to the clamping direction of the metal to be detected, and the clamping block 32 is hinged on the lifting plate 331; the driving member 332 is connected to the fixed plate 31, and is used to drive the lifting plate 331 to move up and down on the fixed plate 31. When the driving member 332 moves, the driving member 332 drives the lifting plate 331 to move, and when the lifting plate 331 moves downward, it drives the clamping block 32 to move, and multiple clamping blocks 32 approach each other to clamp the metal on the fixed plate 31; when the driving member 332 drives the lifting plate 331 to move upward, the lifting plate 331 drives the clamping block 32 to move, and multiple clamping blocks 32 move away from each other, so as to remove the metal on the fixed plate 31.

[0042] In one embodiment, the driving member 332 may be a driving cylinder (not specifically marked in the drawings of this application). The base of the driving cylinder is installed at the bottom of the fixed plate 31, and the output shaft of the driving cylinder is connected to the lifting plate 331, and the movement direction of the driving cylinder is perpendicular to the clamping direction of the metal to be detected. It is understandable that the driving member 332 described in the embodiment of the present disclosure is not limited to the driving cylinder, and may also be other mechanisms that actually lift the lifting plate 331, which will not be described in detail here.

[0043] See also Figure 2 , Figure 3 The second clamping mechanism 4 includes two clamping plates 41 and a power assembly 42; the two clamping plates 41 are slidably connected to the fixed plate 31 through the power assembly 42, wherein the two clamping plates 41 form a second clamping space for the sheet metal, and the clamping plates 41 are arranged in the gap of the clamping block 32; the power assembly 42 is used to drive the two clamping plates 41 to move closer to or away from each other. The set second clamping mechanism 4 facilitates the clamping processing of the sheet metal and improves the application scope of the processing device. Furthermore, it should be noted that when the sheet metal is in the processing frame 2, due to the interference of the clamping plate 41, it is difficult for the sheet metal to contact the electric pulse generating device 1 corresponding to the block metal. Therefore, in the embodiment of the present disclosure, the electric pulse generating device 1 corresponding to the sheet metal is arranged on the top of the processing frame 2 to avoid the interference of the clamping plate 41 (see Figure 1 ).

[0044] See also Figure 2 , Figure 3 The power assembly 42 includes a power screw 421 and a power turntable 422; the power screw 421 is rotatably connected to the side of the fixed plate 31 away from the clamping block 32, wherein the axial direction of the power screw 421 is the same as the movement direction of the fixed plate 31 in the processing frame 2; the two clamping plates 41 are respectively connected to the positive thread segment and the negative thread segment of the power screw 421; and there is no interference between the power screw 421 and the lifting plate 331 (in the embodiment of the present disclosure, the number of clamping blocks 32 is three, in order to ensure the clamping effect on block-shaped metals, their common connection point is located at the center of the fixed plate 31, for this reason, the power screws 421 can be staggered to reduce interference); the power turntable 422 is installed on the power screw 421.

[0045] See also Figure 3 , Figure 4 A groove 411 for accommodating the plate-like metal is provided on one side of the two clamping plates 41 close to each other. When processing the plate-like metal, the plate-like metal is inserted into the groove 411. The provided groove 411 can improve the clamping and fixing effect of the clamping plate 41 on the plate-like metal.

[0047] See also Figure 2 The moving mechanism 5 further includes a limiting screw 53. The limiting screw 53 is threadedly connected to the processing frame 2. The limiting screw 53 can contact the moving wheel 52 on the side of the moving wheel 52 close to the discharge port 22. The limiting screw 53 is used to limit the position of the fixed plate 31 on the moving slide rail 51. It can be understood that the output end of the electric pulse generating device 1 is fixed. When the fixed plate 31 moves in the processing frame 2, when the metal contacts the electric pulse generating device 1, the limiting screw 53 is adjusted, and the position of the moving wheel 52 is limited by the limiting screw 53, so that the fixed plate 31 is kept at a specific position, which is convenient for electric pulse processing of the metal.
