Description

Technical Field

[0001] The present invention relates to the field of metal stamping, and in particular to a multifunctional metal stamping device and a use method thereof. Background Art

[0002] Stamping process is a very common metal machining method. Compared with other metal machining methods, it often has some outstanding advantages, such as high efficiency, low cost, suitability for mass production, and high material utilization rate. In particular, the advantages of high processing efficiency and low cost are the most prominent. Existing stamping dies can often reach a stamping frequency of thousands of times per minute during the metal stamping process.

[0003] However, in the actual production process, the mold will generate friction and heat when stamping the metal sheet. Such a high stamping frequency will often cause heat to accumulate in the mold, causing the mold temperature to rise. If the temperature changes too much, it will often cause the size of each component of the mold to change, thereby affecting the processing accuracy.

[0004] Existing molds often cool down the mold by processing water or oil channels in the mold to allow water or oil to circulate in the mold. However, existing equipment is often unable to obtain the temperature of each position of the mold in real time. During the stamping process, the heat accumulation phenomenon in different positions of the mold is often significantly different. The traditional heat dissipation method may be insufficient due to the fact that the heat accumulation phenomenon in local positions is significantly higher than that in other positions, thereby affecting the processing accuracy. Summary of the Invention

[0005] The present invention provides a multifunctional metal stamping device, which can solve the problem of insufficient heat dissipation caused by the inability to obtain the temperature of a local position in the stamping die in the prior art.

[0006] A multifunctional metal plate stamping device, comprising

[0007] A lower punching base plate, wherein guide pillar blocks are fixedly installed at the front and rear positions on both sides of the lower punching base plate, wherein the guide pillar blocks are processed with through holes in the vertical direction, and a cavity plate is fixedly installed on the lower punching base plate, wherein a forming groove is processed in the cavity plate; The upper stamping base plate is arranged at the upper end of the lower stamping base plate, and the lower end of the upper stamping base plate is fixedly installed with a guide column corresponding to the through-hole position of the guide column block, and the guide column is slidably connected to the through-hole in the guide column block. A core plate is fixedly embedded in the middle position of the lower end of the upper stamping base plate, and a core is fixedly installed on the core plate in the forming groove corresponding to the cavity plate. A cooling pipe for cooling is processed close to the core in the core plate, and a plurality of temperature sensors are arranged on the core plate along the cooling pipe, and the temperature sensors are evenly distributed along the cooling pipe (oil for cooling flows in the cooling pipe), and a reset spring is provided on the guide column block, and the upper and lower ends of the reset spring are respectively pressed on the upper stamping base plate and the lower stamping base plate.

[0008] It should be noted that in the process of stamping the metal plate by the metal plate stamping device, the metal plate is conveyed to the position between the upper stamping base plate and the lower stamping base plate by the metal plate conveying device in the prior art, and the upper stamping base plate is driven to reciprocate in the vertical direction by the punch press. The upper stamping base plate will drive the core to continuously punch the metal plate. Under the impact, shearing and extrusion of the forming grooves on the core and the cavity plate, parts of specific shapes are punched out and fall from the forming grooves in the cavity plate. In this process, the temperature of the core will continue to rise due to friction while it is constantly stamping the metal plate. In order to prevent Excessive temperature causes the shape and size of the core to change, resulting in a decrease in machining accuracy. The pump body inputs oil with a lower temperature into the cooling pipe to take away the excess heat, thereby preventing the core from excessively deforming due to temperature changes. At the same time, temperature sensors evenly distributed along the cooling pipe will measure the temperature of various positions of the core. In this way, even if the temperature of a certain position is too high and the temperature of other positions is normal, the delivery power of the pump body can be increased to increase the flow rate of the oil in the cooling pipe, so that the temperature of the local position can be reduced, thereby preventing the local position from deforming due to high temperature and causing a decrease in machining accuracy.

[0009] In particular, the upper stamping base plate is provided with a lubrication flow groove, which is provided between the cooling pipe and the core, one end of the lubrication flow groove is communicated with the cooling pipe, and the other end of the lubrication flow groove is close to the side wall of the core, and a plurality of lubrication flow grooves are evenly distributed along the side of the core, an oil blocking rod is slidably connected in the cooling pipe, and a control mechanism for controlling the sliding of the oil blocking rod is provided in the core plate.

[0010] It should be noted that during the process of the core stamping the metal plate, the core will generate friction with the metal plate, which will not only cause the core temperature to rise, but also cause the core to wear. By controlling the opening and closing of the oil blocking rod through the control mechanism, the oil in the lubrication flow groove can be quantitatively made to flow along the lubrication flow groove to the surface of the core. For example, when lubrication is needed, the oil blocking rod is controlled by the control mechanism to no longer block the lubrication flow groove. At this time, the oil in the lubrication flow groove can flow out along the lubrication oil groove. When lubrication is not needed or there is enough oil attached to the surface of the core, the oil blocking rod can be controlled by the control mechanism to block the lubrication flow groove. Through the above technical solution, lubrication can be generated on the stamping contact surface during the stamping of the metal plate, thereby reducing friction and wear. While reducing the heat generated by friction, it can also increase the service life of the core.

[0011] In particular, the core plate is provided with a lubrication diffusion groove at a position corresponding to the lubrication flow groove on the side wall of the embedded core, one end of the lubrication diffusion groove is connected to the lubrication flow groove, the lubrication diffusion groove is slanted downward, each lubrication flow groove is connected to multiple lubrication diffusion grooves, and the lubrication diffusion grooves connected to a lubrication flow groove are distributed divergently as a whole.

[0012] It should be noted that in the process of the oil being applied to the side wall of the core, when the oil flows through the lubrication flow groove, it will flow into the various lubrication diffusion grooves. At this time, multiple parts of the core can be exposed to the oil at the same time, thereby increasing the oil being applied to various parts of the core, indirectly improving the work efficiency when stamping metal plates.

[0013] In particular, the control mechanism includes a control slide A and a control motor. A control slide groove A is opened in the core plate. The control slide A is slidably connected in the control slide groove A. The control slide A is fixedly connected to the oil blocking rod. The control motor is fixedly installed in the core plate, and the output shaft of the control motor is threadedly connected to the control slide A.

[0014] It should be noted that when the oil blocking rod is controlled to slide in the lubrication flow groove by the control mechanism, the output shaft of the control motor is controlled to rotate, and the output shaft of the control motor will be threadedly connected to the control slide A, thereby controlling the control slide A to slide along the control groove A, thereby driving the oil blocking rod to slide in the lubrication groove.

[0015] In particular, the control mechanism includes a control slide B, a control slide groove B is opened in the core plate, the control slide B and the control slide groove B are slidably connected, the control slide B is fixedly connected to the oil blocking rod, an expansion groove is opened at the upper end of the core plate, the expansion groove is filled with expansion liquid, the core plate has expansion slides symmetrically on both sides of the expansion groove, the expansion slide is slidably connected in the expansion slide, a through groove is opened between the expansion slide and the expansion groove to connect the two, a push rod fixedly connected to the expansion slide is slidably connected in the through groove, the expansion slide slide slides through the core plate and is fixedly connected to the control slide B.

[0016] It should be noted that when the temperature of the core rises due to high-frequency stamping, the core mold will drive the temperature of the core plate to rise. After the temperature rises, the core plate will heat the expansion liquid therein. The expansion liquid expands due to heat, and its volume will increase. At this time, the expanded liquid will push the push rod, causing the push rod and the expansion slide to slide synchronously. The expansion slide will drive the control slide B to slide in the control slide B, and the control slide B will drive the oil blocking rod to disengage from the lubrication flow groove, so that the oil will flow along the lubrication flow groove into the side of the core. Because the temperature of the core and core plate is too high, it is most likely caused by excessive friction between the core and the metal plate. The above-mentioned device uses the expansion relationship between temperature and liquid to automatically make the oil flow to the surface of the core, thereby reducing the friction coefficient between the core and the metal plate, reducing the generation of core wear while also reducing heat generation.

[0017] In particular, the core plate is provided with a main heat dissipation groove at the upper end of the through groove, and the main heat dissipation groove penetrates the opposite side of the core plate. The core plate is provided with a volatilization hole at one end of the through groove close to the expansion chute, and the volatilization hole connects the through groove with the main heat dissipation groove.

[0018] It should be noted that when the temperature rises too high, the expanding liquid will continue to push the push rod, exposing the volatilization hole. The liquid will then enter the main heat dissipation tank from the volatilization hole and quickly spread out in the main heat dissipation tank to increase the heating area, and then absorb heat and volatilize. In this process, it will quickly absorb heat, thereby reducing the temperature of the core plate and core. A hole for replenishing the expanding liquid is opened on the core plate, which is usually covered with a lid.

[0019] Particularly, auxiliary heat dissipation grooves are provided on the upper side of the main heat dissipation groove in a direction perpendicular to the main heat dissipation groove, and a plurality of auxiliary heat dissipation grooves are evenly distributed along the main heat dissipation groove.

[0020] It should be noted that by providing auxiliary heat dissipation slots, the heat dissipation area can be further increased, and the heat dissipation efficiency can be further improved.

[0021] Particularly, a plurality of annular notches are processed on the oil blocking rod, and a plurality of sealing strips are fixedly embedded on the side surface of the oil blocking rod.

[0022] It should be noted that by processing multiple annular grooves on the oil blocking rod and embedding sealing strips on the side of the oil blocking rod, the sealing performance of the oil blocking rod in the lubrication flow groove can be effectively improved to prevent leakage when the oil does not need to be applied to the surface of the core.

[0023] In particular, the upper stamping base plate and the lower stamping base plate are both rectangular, and the upper stamping base plate is fixedly installed with a hanger on both sides of its longer end, and a clamping plate is slidably suspended on the hanger, and the clamping plate is processed into a through shape at the position corresponding to the core, and a clamping spring is sleeved on the hanger, and the upper and lower ends of the clamping spring are respectively pressed against the upper stamping base plate and the clamping plate.

[0024] It should be noted that in the process of punching the metal plate, when the upper punching base plate approaches the lower punching base plate, the clamping plate will first be pressed on the metal plate to be punched, and the clamping spring will be compressed. Then the core will punch the metal plate. After the punching is completed, when the upper punching base plate is away from the lower punching base plate, the clamping plate will be away from the upper punching base plate under the rebound action of the clamping spring, thereby resetting. The advantage of this is that when punching the metal plate, the four sides of the metal plate where the metal plate is punched are pulled to prevent the metal plate from twisting and deformation due to punching.

[0025] The present invention also provides a method for using the multifunctional metal plate stamping device, comprising the following steps: S1: The punch press drives the upper punch base to reciprocate in the vertical direction. The upper punch base drives the core to continuously punch out the metal plate. Under the impact, shearing and extrusion of the core and the forming groove on the cavity plate, parts with specific shapes are punched out and fall out of the forming groove in the cavity plate. S2: The oil with lower temperature is input into the cooling pipe through the pump body to take away the excess heat generated by the punching friction; S3: Temperature sensors evenly distributed along the cooling pipes measure the temperature of various locations on the core. When it is detected that the core or core plate has a higher temperature locally or overall, the oil flow rate in the cooling pipes is increased by increasing the pump's delivery power.

[0026] Beneficial effects: 1. The present invention measures the temperature of various positions of the core through temperature sensors evenly distributed along the cooling pipe. When it is detected that the temperature of the core or the core plate is locally or overall high, the pump delivery power is increased to increase the flow rate of the oil in the cooling pipe, thereby reducing the temperature of the core or the core plate. This solves the problem that traditional heat dissipation methods may cause insufficient heat dissipation due to the fact that the heat accumulation in local positions is significantly higher than that in other positions, thereby affecting the processing accuracy.

[0027] 2. The present invention controls the oil blocking rod through a control mechanism so that it no longer blocks the lubrication flow groove. At this time, the oil in the lubrication flow groove can flow out along the lubrication oil groove. When there is no need for lubrication or there is enough oil attached to the surface of the core, the oil blocking rod can be controlled by the control mechanism to block the lubrication flow groove. Through the above technical solution, lubrication can be generated on the stamping contact surface during the stamping of the metal plate, thereby reducing friction and wear. While reducing the heat generated by friction, it can also increase the service life of the core.

[0028] 3. In the present invention, when the temperature of the core rises due to high-frequency stamping, the core mold will drive the temperature of the core plate to rise. After the temperature rises, the core plate will heat the expansion liquid therein. The expansion liquid expands due to heat, and its volume will increase. At this time, the expanded liquid will push the push rod, causing the push rod and the expansion slide to slide synchronously. The expansion slide will drive the control slide B to slide in the control slide groove B, and the control slide B will drive the oil blocking rod to disengage from the lubrication flow groove, so that the oil enters the side of the core along the lubrication flow groove. Because the temperature of the core and the core plate is too high, it is most likely caused by excessive friction between the core and the metal plate. The above-mentioned device uses the expansion relationship between temperature and liquid to automatically make the oil flow to the surface of the core, thereby reducing the friction coefficient between the core and the metal plate, reducing the generation of core wear while also reducing heat generation.

[0029] 4. In the present invention, when the temperature rises too high, the expanding liquid will continue to push the push rod, exposing the volatilization hole. The liquid will then enter the main heat dissipation groove from the volatilization hole and quickly spread out in the main heat dissipation groove to increase the heating area, and then absorb heat and volatilize. In this process, heat will be absorbed quickly, thereby preventing damage to mold-related parts due to excessive temperature. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0033] like Figures 1 to 12 As shown, the present invention provides a multifunctional metal plate stamping device, comprising

[0034] A lower punch base plate 1, wherein guide pillar blocks 11 are fixedly installed at the front and rear positions on both sides of the lower punch base plate 1, and the guide pillar blocks 11 are processed with through holes in the vertical direction. A cavity plate 2 is fixedly installed on the lower punch base plate 1, and a forming groove 21 is processed in the cavity plate 2; The upper stamping base plate 3 is arranged at the upper end of the lower stamping base plate 1, and the lower end of the upper stamping base plate 3 is fixedly installed with a guide column 31 corresponding to the through hole position of the guide column block 11, and the guide column 31 is slidably connected to the through hole in the guide column block 11, and a core plate 4 is fixedly embedded in the middle position of the lower end of the upper stamping base plate 3, and a core 41 is fixedly installed on the core plate 4 corresponding to the forming groove 21 of the cavity plate 2, and a cooling pipe 42 for cooling is processed in the core plate 4 close to the core 41, and a plurality of temperature sensors are arranged on the core plate 4 along the cooling pipe 42, and the temperature sensors are evenly distributed along the cooling pipe 42 (oil for cooling flows in the cooling pipe 42), and a reset spring 111 is sleeved on the guide column block 11, and the upper and lower ends of the reset spring 111 are respectively pressed on the upper stamping base plate 3 and the lower stamping base plate 1.

[0035] It should be noted that in the process of stamping the metal plate by the metal plate stamping device, the metal plate is conveyed to the position between the upper stamping base plate 3 and the lower stamping base plate 1 by the metal plate conveying device in the prior art, and the upper stamping base plate 3 is driven by the punch press to reciprocate in the vertical direction. The upper stamping base plate 3 will drive the core 41 to continuously punch the metal plate. Under the impact, shearing and extrusion of the core 41 and the forming groove on the cavity plate 2, parts of specific shapes are punched out and fall from the forming groove 21 in the cavity plate 2. In this process, the temperature of the core 41 will continue to rise due to friction while it is constantly stamping the metal plate. In order to prevent In order to prevent the core 41 from changing in size and causing a reduction in processing accuracy due to excessively high temperature, oil with a lower temperature is input into the cooling pipe 42 through the pump body, thereby taking away excess heat and preventing the core 41 from excessively deforming due to temperature changes. At the same time, temperature sensors evenly distributed along the cooling pipe 42 will measure the temperature of various positions of the core 41. In this way, even if the temperature of a certain position is too high and the temperature of other positions is normal, the flow rate of the oil in the cooling pipe 42 can be increased by increasing the delivery power of the pump body, so that the temperature of the local position can be reduced, thereby preventing the local position from deforming due to high temperature and causing a reduction in processing accuracy.

[0036] like Figure 1 、 Figures 3 to 6 As shown, the upper stamping base plate 3 is provided with a lubrication flow groove 32, and the lubrication flow groove 32 is provided between the cooling pipe 42 and the core 41. One end of the lubrication flow groove 32 is communicated with the cooling pipe 42, and the other end of the lubrication flow groove 32 is close to the side wall of the core 41. There are multiple lubrication flow grooves 32 evenly distributed along the side of the core 41, and an oil blocking rod 43 is slidably connected in the cooling pipe 42. The core plate 4 is provided with a control mechanism 5 for controlling the sliding of the oil blocking rod 43.

[0037] It should be noted that, in the process of the core 41 stamping the metal plate, the core 41 will generate friction with the metal plate, which will not only cause the temperature of the core 41 to rise, but also cause wear on the core 41. By controlling the opening and closing of the oil blocking rod 43 through the control mechanism 5, the oil in the lubricating flow groove 32 can be quantitatively made to flow along the lubricating flow groove 32 to the surface of the core 41. For example, when lubrication is needed, the oil blocking rod 43 is controlled by the control mechanism 5 to no longer block the lubricating flow groove 32. At this time, the oil in the lubricating flow groove 32 can flow out along the lubricating oil groove. When lubrication is not needed or when there is enough oil attached to the surface of the core 41, the oil blocking rod 43 can be controlled by the control mechanism 5 to block the lubricating flow groove 32. Through the above technical solution, lubrication can be generated on the stamping contact surface during the stamping of the metal plate, thereby reducing friction and wear. While reducing the heat generated by friction, it can also improve the service life of the core 41.

[0038] like Figure 3 and Figure 12 As shown, the core plate 4 is provided with a lubrication diffusion groove 44 at the position of the side wall of the interlocking core 41 corresponding to the lubrication flow groove 32, and one end of the lubrication diffusion groove 44 is connected to the lubrication flow groove 32, and the lubrication diffusion groove 44 is in a downward slanting shape. Each lubrication flow groove 32 is connected to multiple lubrication diffusion grooves 44, and the lubrication diffusion grooves 44 connected to a lubrication flow groove 32 are distributed in a divergent shape as a whole.

[0039] It should be noted that, in the process of the oil being applied to the side wall of the core 41, when the oil flows through the lubrication flow groove 32, it will flow into each lubrication diffusion groove 44. At this time, multiple parts of the core 41 can be in contact with the oil at the same time, thereby increasing the oil being applied to various parts of the core 41, indirectly improving the work efficiency when stamping the metal plate.

[0040] like Figure 1 、 Figure 5 and Figure 6 As shown, the control mechanism 5 includes a control slide A51 and a control motor 52. A control slide groove A45 is opened in the core plate 4. The control slide A51 is slidably connected in the control slide groove A45. The control slide A51 is fixedly connected to the oil blocking rod 43. The control motor 52 is fixedly installed in the core plate 4. The output shaft of the control motor 52 is threadedly connected to the control slide A51.

[0041] It should be noted that when the oil-blocking rod 43 is controlled to slide in the lubrication groove 32 by the control mechanism 5, the output shaft of the control motor 52 is controlled to rotate, and the output shaft of the control motor 52 is threadedly connected to the control slide A51, thereby controlling the control slide A51 to slide along the control groove A45, thereby driving the oil-blocking rod 43 to slide in the lubrication groove.

[0042] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 7 and Figure 8 As shown, the control mechanism 5 includes a control slide B53, a control slide B46 is provided in the core plate 4, the control slide B53 and the control slide B46 are slidably connected, the control slide B53 is fixedly connected to the oil blocking rod 43, an expansion groove 47 is provided at the upper end of the core plate 4, the expansion groove 47 is filled with expansion liquid, the core plate 4 is symmetrically provided with expansion slides 48 on both sides of the expansion groove 47, an expansion slide 54 is slidably connected in the expansion slide 48, a through groove 49 is provided between the expansion slide 48 and the expansion groove 47 to connect the two, a push rod 541 fixedly connected to the expansion slide 54 is slidably connected in the through groove 49, the expansion slide 54 slides through the core plate 4 and is fixedly connected to the control slide B53.

[0043] It should be noted that when the temperature of the core 41 rises due to high-frequency stamping, the core will drive the temperature of the core plate 4 to rise. After the temperature rises, the core plate 4 will heat the expansion liquid therein. The expansion liquid expands due to heat, and its volume will increase. At this time, the expanded liquid will push the push rod 541, causing the push rod 541 and the expansion slide 54 to slide synchronously. The expansion slide 54 will drive the control slide B53 to slide in the control slide groove B46, and the control slide B53 will drive the oil blocking rod 43 to disengage from the lubrication flow groove 32, so that the oil enters the side of the core 41 along the lubrication flow groove 32. Because the temperature of the core 41 and the core plate 4 is too high, it is most likely caused by excessive friction between the core 41 and the metal plate. The above-mentioned device uses the expansion relationship between temperature and liquid to automatically make the oil flow to the surface of the core 41, thereby reducing the friction coefficient between the core 41 and the metal plate, reducing the wear of the core 41 and also reducing the heat generation.

[0044] like Figure 1 、 Figures 7 to 10 As shown, the core plate 4 is provided with a main heat dissipation groove 491 at the upper end of the through groove 49, and the main heat dissipation groove 491 penetrates the opposite side of the core plate 4. The core plate 4 is provided with a volatilization hole 492 at one end of the through groove 49 close to the expansion chute 48, and the volatilization hole 492 connects the through groove 49 with the main heat dissipation groove 491.

[0045] It should be noted that when the temperature rises too high, the expanded liquid will continue to push the push rod 541, exposing the volatilization hole 492, and the liquid will enter the main heat dissipation groove 491 from the volatilization hole 492, and quickly spread out in the main heat dissipation groove 491 to increase the heating area, and then absorb heat and evaporate. In this process, it will quickly absorb heat, thereby reducing the temperature of the core plate 4 and the core 41. A hole for replenishing the expanded liquid is opened on the core plate 4, and it is usually covered with a lid.

[0046] like Figure 9 As shown, auxiliary heat dissipation grooves 493 are opened on the main heat dissipation groove 491 in a direction perpendicular to the main heat dissipation groove 491 , and a plurality of auxiliary heat dissipation grooves 493 are evenly distributed along the main heat dissipation groove 491 .

[0047] It should be noted that, by providing the auxiliary heat dissipation grooves 493 , the heat dissipation area can be further increased, thereby further improving the heat dissipation efficiency.

[0048] like Figure 11 As shown, the oil blocking rod 43 is processed with multiple annular notches, and multiple sealing strips are fixedly embedded on the side of the oil blocking rod 43.

[0049] It should be noted that by processing multiple annular grooves on the oil blocking rod 43 and embedding sealing strips on the side of the oil blocking rod 43, the sealing performance of the oil blocking rod 43 in the lubrication flow groove 32 can be effectively improved to prevent leakage when there is no need to apply oil to the surface of the core 41.

[0050] like Figure 1 As shown, the upper stamping base plate 3 and the lower stamping base plate 1 are both rectangular, and the upper stamping base plate 3 is fixedly installed with a suspension rod 33 on both sides of its longer end, and the clamping plate 6 is slidably suspended on the suspension rod 33. The clamping plate 6 is processed into a through shape at the position corresponding to the core 41, and a clamping spring 61 is sleeved on the suspension rod 33. The upper and lower ends of the clamping spring 61 are respectively pressed against the upper stamping base plate 3 and the clamping plate 6.

[0051] It should be noted that during the punching process of the metal plate, when the upper punching base plate 3 approaches the lower punching base plate 1, the clamping plate 6 will first be pressed on the metal plate to be punched, and the clamping spring 61 will be compressed. Then the core 41 will punch the metal plate. After the punching is completed, when the upper punching base plate 3 is away from the lower punching base plate 1, the clamping plate 6 will be away from the upper punching base plate 3 under the rebound action of the clamping spring 61, thereby resetting. The advantage of this is that when punching the metal plate, the four sides of the punched position of the metal plate are pulled to prevent the metal plate from twisting and deforming due to punching.

[0052] The present invention also provides a method for using the multifunctional metal plate stamping device, comprising the following steps: S1: The punch press drives the upper punch base plate 3 to reciprocate in the vertical direction. The upper punch base plate 3 drives the core 41 to continuously punch out the metal sheet. Under the impact, shearing and extrusion of the core 41 and the forming groove on the cavity plate 2, parts with specific shapes are punched out and fall out of the forming groove 21 in the cavity plate 2; S2: The pump body inputs the oil with lower temperature into the cooling pipe 42 to remove the excess heat generated by the punching friction; S3: Temperature sensors evenly distributed along the cooling pipe 42 measure the temperature of various positions of the core 41. When it is detected that the temperature of the core 41 or the core plate 4 is locally or as a whole high, the oil flow rate in the cooling pipe 42 is increased by increasing the delivery power of the pump body.

[0053] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
