Description

Technical Field

[0001] The invention belongs to the field of punching and cutting dies, in particular to a punching die for removing slag bags from a material handle of a motor housing. Background Art

[0002] The formation of slag bags is a common problem in the casting process of motor housings. Slag bags are usually formed by the reaction of molten metal with the mold or molding sand during the pouring process, or by the failure to discharge impurities and gases contained in the molten metal in time. These slag bags may affect the quality and performance of the castings, so corresponding measures need to be taken to eliminate them. The most commonly used traditional method is to punch the mold, place the motor housing with slag bags around it in the corresponding lower module slot, fix it, and then through the descent of the upper module, the upper module can punch the slag bags until the motor housing is wrapped by the upper and lower modules, and the slag bags outside the motor housing are removed.

[0003] A patent document with publication number CN216461703U discloses a motor housing slag bag punching mechanism, including a punching die base, a punching die bottom plate and a receiving plate, leg columns are installed at the left and right ends of the upper side of the punching die base, and a terminal box is arranged on the left side of the upper end of the leg column, a fixed plate is fixedly connected to the front side of the upper end of the leg column, and a mounting block is slidably connected to the front side of the leg column, a support plate is arranged on the top of the mounting block, the punching die bottom plate is fixedly connected to the upper side of the support plate, and a punching die is attached to the bottom end of the punching die bottom plate, and an organic species identification sensor is arranged at the rear end of the punching die bottom plate.

[0004] In the traditional technical solution, the slag bags are removed from the motor housing with slag bags around it by means of a punching die. However, this method is not very applicable to the motor housing with relatively complex slag bags. After the relatively complex slag bags are separated from the motor housing, the slag bags will fall onto the lower module. In the absence of external force, the slag bags will not be separated from the lower module, affecting the next punching action. However, if the manual knocking mode is used for the motor housing with relatively complex slag bags, the product will easily be deformed when knocking the slag bags, making it impossible for customers to assemble it.

[0005] To this end, the present invention provides a punching die for removing slag bags from the material handle of a motor housing. Summary of the invention

[0016] Preferably, the end of the connecting air pipe is located inside the matching groove, and the connecting air pipe and the air outlet pipe are located on the same vertical axis.

[0017] The beneficial effects of the present invention are as follows: 1. The punching die for removing the slag bag of the material handle of the motor casing described in the present invention is implemented by placing the motor casing molded part into the corresponding groove of the lower module, the groove opened in the lower module is fitted with the lower part of the motor casing molded part, and after the motor casing molded part is positioned, the upper module is driven by the internal electric power of the punching device to descend until the upper module is fitted with the lower module, so that the motor casing molded part is located inside the upper module and the lower module. During the descending process of the upper module, the lower part of the upper module will gradually contact the material handle body, the front end extended slag bag and the annular slag bag. Because the upper module will eventually fit with the lower module, the material handle body, the front end extended slag bag and the annular slag bag will be punched out by the descending upper module, that is, the material handle body, the front end extended slag bag and the annular slag bag will be separated from the motor casing molded part, because the inner cavities of the upper module and the lower module are matched with the motor casing molded part, the motor casing molded part will not be damaged when the slag bag is removed by punching.

[0018] 2. The die for removing slag bags from the material handle of a motor casing described in the present invention drives the driven gear to rotate through the movement of the rack, and the rotating driven gear drives the rotating block and the eccentric block to rotate. When the spring guide column is in a natural state, the rotation of the rotating block will allow the eccentric block to contact the motor casing molded part, thereby generating knocking. When the rotating block continues to rotate, the spring set in the spring guide column will be compressed, allowing the eccentric block to move toward the rotating block, facilitating the continued rotation of the rotating block. The continuous rotation of the rotating block will cause the eccentric block to continuously knock the motor casing molded part. The vibration of the motor casing molded part will cause the motor casing molded part to separate from the lower module and the upper module, and the vibration of the motor casing molded part will produce a detection effect. Multiple knocks are used to observe whether the inner and outer surfaces of the subsequent motor casing molded parts show defective performance.

[0019] 3. The punching die for removing slag bags from the material handle of a motor housing described in the present invention, when the upper module is pressed down to perform punching and cutting, the upper guide column will also descend. During the descending process of the upper guide column, the bottom of the upper guide column will contact the bottom end of the lifting component, thereby driving the lifting component to descend on the outside of the fixed column, compressing the second compression spring at this time. In the punching step, the lower guide column slides inside the upper guide column to play a guiding role, avoiding position deviation when the upper module descends. After the punching and cutting is completed, the upper module needs to rise, and the compressed second compression spring will exert an upward force on the upper module under the action of the restoring force to assist the subsequent rising step of the upper module.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0024] like Figure 1-4 As shown, a punching die for removing the slag bag of a material handle of a motor housing according to an embodiment of the present invention comprises a punching device 1, wherein the punching device 1 comprises an upper module 2 and a lower module 4 for punching the slag bag, wherein the upper module 2 is located directly above the lower module 4, and the punching device 1 comprises a body, wherein a plurality of guide column assemblies 3 are installed inside the body, and a motor housing forming part 5 is placed inside the lower module 4, wherein a material handle body 51 is provided on the side of the motor housing forming part 5, a front end extending slag bag 52 is provided at one end of the motor housing forming part 5, and an annular slag bag 53 is provided at the other end of the motor housing forming part 5; A telescopic motor 11 is fixedly installed at the top of the body of the punching and shearing device 1, and an upper die pull head 111 is installed at the end of the telescopic motor 11. The upper die pull head 111 is located above the front end extended slag bag 52, and an upper die punch 12, an upper die punch 2 13 and an upper die punch 3 14 are also installed inside the punching and shearing device 1. The upper die punch 12, the upper die punch 2 13 and the upper die punch 3 14 have a structure similar to that of a telescopic column, and generate impact force on the object below through the telescopic structure. The upper die punch 12, the upper die punch 2 13 and the upper die punch 3 14 are located directly above the material handle body 51 and the annular slag bag 53 respectively, and the upper die punch 12, the upper die punch 2 13 and the upper die punch 3 14 are distributed on the outside of the upper module 2.

[0025] Specifically, the motor housing molded part 5 is placed inside the corresponding groove of the lower module 4, and the groove opened in the lower module 4 fits with the lower part of the motor housing molded part 5. After the motor housing molded part 5 is positioned, the upper module 2 is driven by the internal electric power of the punching device 1 to descend until the upper module 2 fits with the lower module 4, so that the motor housing molded part 5 is inside the upper module 2 and the lower module 4. During the descent of the upper module 2, the lower part of the upper module 2 will gradually contact the material handle 51, the front end extended slag bag 52 and the annular slag bag 53, because the upper module 2 will eventually fit with the lower module 4. Therefore, the material handle body 51, the front end extension slag bag 52 and the annular slag bag 53 will be punched out by the descending upper module 2, that is, the material handle body 51, the front end extension slag bag 52 and the annular slag bag 53 will be separated from the motor housing molded part 5, but the material handle body 51, the front end extension slag bag 52 and the annular slag bag 53 are difficult to automatically detach from the top of the lower module 4, so the upper mold pull head 111 is driven by the telescopic motor 11 to shrink, and the pull head at the end of the upper mold pull head 111 will contact the extended part of the front end extension slag bag 52, driving the front end extension slag bag 52 to move, so that the front end extension slag bag 52 is removed from the lower mold 4. The upper part of the upper module 4 is detached from the upper part, and the upper die punch 2 13, the upper die punch 1 12 and the upper die punch 3 14 distributed on the outside of the upper module 2 will be located just above the slag bag. When the upper module 2 and the lower module 4 are fitted together, the ends of the upper die punch 2 13, the upper die punch 1 12 and the upper die punch 3 14 are extended by electric drive to press down the material handle 51 and the annular slag bag 53, so that the material handle 51 and the annular slag bag 53 are detached from the top of the lower module 4. After the punching is completed, the slag bag 52 extending from the front end after the punching is driven to move through the extension and contraction of the upper die pull head 111, and then detached from the lower module. 4, the ends of the upper die punch 2 13, the upper die punch 1 12 and the upper die punch 3 14 are extended, and at this time the ends of the three are outside the lower die block 4, and the extended ends of the three produce an impact force on the material handle body 51 and the annular slag bag 53, so that the material handle body 51 and the annular slag bag 53 are separated from the lower die block 4. In this way, when it comes to the motor housing molded part 5 with a complex slag bag around it, repeated punching work can be performed all the time, and because the inner cavities of the upper die block 2 and the lower die block 4 are matched with the motor housing molded part 5, the motor housing molded part 5 will not be damaged when the slag bag is removed by punching.

[0026] like Figure 5-7As shown, a module cavity 21 is provided inside the upper module 2, and an auxiliary cavity 22 is also provided inside the upper module 2. The auxiliary cavity 22 is communicated with the module cavity 21, and a vibration detection component 8 is installed inside the auxiliary cavity 22. The vibration detection component 8 includes a piston bar 81 slidably installed inside the upper module 2 and a rack 82 fixedly installed on one side of the piston bar 81. The rack 82 is meshedly connected with a driven gear 83 on the side, and an eccentric member 84 is connected to the driven gear 83 below through an axis. A connecting spring 85 is fixedly connected to one end of the rack 82, and the connecting spring 85 is fixedly connected to the inner wall of the upper module 2.

[0027] Specifically, the piston bar 81 slidably installed inside the upper module 2 is pushed to move, that is, at this time, the rack 82 moves from the initial position, the connecting spring 85 is compressed, and the rack 82 drives the driven gear 83 to rotate when it moves. The rotation of the driven gear 83 drives the eccentric member 84 to rotate. The movement of the rack 82 can drive the driven gear 83 to rotate several times. In the initial state, the eccentric structure of the eccentric member 84 does not contact the motor housing molded part 5. The rotated eccentric member 84 will knock the motor housing molded part 5 multiple times through the eccentric structure, thereby causing the motor housing to be molded. The molded part 5 produces a slight vibration and no longer applies a driving force to the rack 82. The restored connecting spring 85 drives the rack 82 back to the initial position, allowing the eccentric component 84 to rotate for a second time, and knocking the motor housing molded part 5 multiple times again, which is conducive to the motor housing molded part 5 to separate from the upper module 2 and the lower module 4, and improves the problem of being difficult to demold after punching the slag bag of the motor housing molded part 5 because the motor housing molded part 5 is tightly fitted with the upper module 2 and the lower module 4. In addition, multiple vibrations will perform vibration detection on the motor housing molded part 5 to prevent the motor housing molded part 5 from becoming a defective product.

[0028] like Figure 7 As shown, the eccentric member 84 includes a rotating block 841 connected to the driven gear 83 via a shaft, an eccentric block 842 is movably mounted on one side of the rotating block 841, and a plurality of spring guide columns 843 are movably mounted between the eccentric block 842 and the rotating block 841.

[0029] Specifically, the movement of the rack 82 drives the driven gear 83 to rotate, and the rotating driven gear 83 drives the rotating block 841 and the eccentric block 842 to rotate. When the spring guide column 843 is in a natural state, the rotation of the rotating block 841 will cause the eccentric block 842 to contact the side of the motor housing molded part 5, thereby generating a knock. When the rotating block 841 continues to rotate, the spring set in the spring guide column 843 will be compressed, allowing the eccentric block 842 to move toward the rotating block 841 to facilitate the continued rotation of the rotating block 841. The continuous rotation of the rotating block 841 will cause the eccentric block 842 to continuously knock the motor housing molded part 5, thereby causing the motor housing molded part 5 to produce a slight vibration effect. The vibration of the motor housing molded part 5 will cause the motor housing molded part 5 to separate from the lower module 4 and the upper module 2, and the vibration of the motor housing molded part 5 will have a detection effect, and multiple knocks are used to observe whether the inner and outer surfaces of the subsequent motor housing molded part 5 have defective performance.

[0030] like Figure 8 As shown, a connecting air pipe 23 is fixedly installed on the side of the upper module 2, and a first limit bar 24 and a second limit bar 25 are fixedly installed inside the upper module 2. The piston bar 81 slides inside the first limit bar 24, and the rack 82 slides inside the second limit bar 25. The second limit bar 25 is set with an opening on one side facing the driven gear 83.

[0031] Specifically, the gas is transported in through the upper module 2, and the gas enters the second limit bar 25, thereby pushing the piston bar 81 inside the second limit bar 25 to slide. At this time, the rack 82 will slide inside the second limit bar 25, and the sliding rack 82 drives the driven gear 83 to rotate to complete the subsequent demolding and vibration detection work.

[0032] like Figure 9-10 As shown, the guide column assembly 3 includes an upper guide column 6 and a lower guide column 7 installed inside the punching device 1, the upper guide column 6 and the lower guide column 7 are on the same vertical axis, the upper end of the upper guide column 6 is fixedly installed with a connecting air pipe 61, the connecting air pipe 61 is connected to the connecting air pipe 23, the lower guide column 7 includes a fixed column 73 and a lifting component 72 slidably installed on the outside of the fixed column 73, the upper end of the fixed column 73 is fixedly installed with a limit plate 71, the limit plate 71 is used to prevent the lifting component 72 from detaching, and the lower side of the lifting component 72 is fixedly installed with a second compression spring 74, one end of the second compression spring 74 is fixedly connected to the inside of the punching device 1.

[0033] Specifically, when the upper module 2 is pressed down for punching, the upper guide column 6 will also descend. During the descending process of the upper guide column 6, the bottom of the upper guide column 6 will contact the bottom end of the lifting component 72, thereby driving the lifting component 72 to descend on the outside of the fixed column 73, compressing the second compression spring 74 at this time. In the punching step, the lower guide column 7 slides inside the upper guide column 6 to play a guiding role, avoiding position deviation when the upper module 2 descends. After the punching is completed, the upper module 2 needs to rise. The compressed second compression spring 74, under the action of the restoring force, will exert an upward force on the upper module 2 to assist the subsequent ascending step of the upper module 2. Embodiment 2

[0034] like Figure 11-13 As shown, compared with Example 1, another implementation of the present invention is: a lifting ring 721 is fixedly installed on the bottom of the lifting component 72, a first annular airbag 722 is fixedly installed inside the lifting ring 721, a plurality of telescopic air tubes 723 are installed inside the lifting component 72, one end of the telescopic air tube 723 is located inside the lifting ring 721, and one end of the telescopic air tube 723 is communicated with the first annular airbag 722, a plurality of hidden grooves 731 are opened inside the fixed column 73, and a plurality of telescopic air tubes 723 are installed inside the corresponding hidden grooves 731.

[0035] A second annular airbag 711 is fixedly installed inside the limiting plate 71, and an air outlet pipe 712 is also fixedly installed inside the limiting plate 71. The second annular airbag 711 is connected to one end of the telescopic air pipe 723. An air supply device is fixedly installed inside the fixed column 73, and the air supply device is connected to the air outlet pipe 712.

[0036] A matching groove 62 is provided inside the upper guide column 6, the diameter of which is larger than the diameter of the limiting plate 71 and smaller than the diameter of the lifting ring 721, the end of the connecting air pipe 61 is located inside the matching groove 62, and the connecting air pipe 61 and the air outlet pipe 712 are on the same vertical axis.

[0037] Specifically, when the upper module 2 descends, the upper guide column 6 will also descend. At this time, the limit plate 71 and the upper end of the lifting member 72 will be in the matching groove 62. When the end of the upper guide column 6 contacts the lifting ring 721, the lifting member 72 will be driven to descend. At this time, the second compression spring 74 is compressed and the plurality of telescopic air pipes 723 are stretched, but the telescopic air pipes 723 are always limited in the hidden strip groove 731 and will not affect the lifting of the lifting member 72. After the lifting member 72 descends to the limit position, the upper guide column 6 continues to descend, causing the end of the upper guide column 6 to squeeze the first protruding portion. The annular airbag 722, the gas inside the first annular airbag 722 is transported to the inside of the second annular airbag 711 through a plurality of telescopic air tubes 723, so that the second annular airbag 711 is inflated and expanded. The expanded second annular airbag 711 is in close contact with the inner wall of the matching groove 62, and the gas is supplied to the inside of the outlet pipe 712 through the gas supply device. The gas will enter the inside of the connecting air pipe 61 through the outlet pipe 712. At this time, the expanded second annular airbag 711 can prevent the gas from leaking at the contact position between the outlet pipe 712 and the connecting air pipe 61. The gas passes through the connecting air pipe 61 and the connecting air pipe 2 3 enters the first limit strip 24, thereby pushing the piston strip 81 to slide, and the eccentric member 84 plays a role through the transmission of gas, so that the motor housing molded part 5 is easy to demould and perform vibration detection. When the stamping work is completed, the upper module 2 rises and drives the upper guide column 6 to rise. At this time, the motor housing molded part 5 is between the lower module 4 and the upper module 2. When the upper guide column 6 rises, there will be a gap between the connecting air pipe 61 and the outlet pipe 712, and the gas inside the first limit strip 24 will be released through the connecting air pipe 23 and the connecting air pipe 61. Under the action of the restoring force, the rack 82 and the piston bar 81 move toward the connecting air pipe 23, and drive the driven gear 83 and the rotating block 841 to rotate again, and knock the motor housing molded part 5 again. The secondary knocking effectively improves the demoulding effect of the motor housing molded part 5 and improves the vibration detection data. In this process, the air supply equipment does not need to supply air again, that is, only one gas supply is needed to complete the vibration work of the motor housing molded part 5 twice, so as to avoid the subsequent motor housing molded part 5 being difficult to demould and the occurrence of defects.

[0038] Working principle: when the upper module 2 descends, the upper guide column 6 will also descend. At this time, the limit plate 71 and the upper end of the lifting member 72 will be in the matching groove 62. When the end of the upper guide column 6 contacts the lifting ring 721, it will drive the lifting member 72 to descend. At this time, the second compression spring 74 is compressed, and the multiple telescopic air pipes 723 are stretched, but the telescopic air pipes 723 are always limited in the hidden strip groove 731, which will not affect the lifting of the lifting member 72. After the lifting member 72 descends to the limit position, the upper guide column 6 continues to descend, which will cause the end of the upper guide column 6 to squeeze the first protruding part. The annular airbag 722, the gas inside the first annular airbag 722 is transported to the inside of the second annular airbag 711 through a plurality of telescopic air tubes 723, so that the second annular airbag 711 is inflated and expanded. The expanded second annular airbag 711 is in close contact with the inner wall of the matching groove 62, and the gas is supplied to the inside of the outlet pipe 712 through the gas supply device. The gas will enter the inside of the connecting air pipe 61 through the outlet pipe 712. At this time, the expanded second annular airbag 711 can prevent the gas from leaking at the contact position between the outlet pipe 712 and the connecting air pipe 61. The gas passes through the connecting air pipe 61 and the connecting air pipe 2 3 enters the first limit strip 24, thereby pushing the piston strip 81 to slide, and the eccentric member 84 plays a role through the transmission of gas, so that the motor housing molded part 5 is easy to demould and perform vibration detection. When the stamping work is completed, the upper module 2 rises and drives the upper guide column 6 to rise. At this time, the motor housing molded part 5 is between the lower module 4 and the upper module 2. When the upper guide column 6 rises, there will be a gap between the connecting air pipe 61 and the outlet pipe 712, and the gas inside the first limit strip 24 will be released through the connecting air pipe 23 and the connecting air pipe 61. Under the action of the restoring force, the rack 82 and the piston bar 81 move toward the connecting air pipe 23, and drive the driven gear 83 and the rotating block 841 to rotate again, and knock the motor housing molded part 5 again. The secondary knocking effectively improves the demoulding effect of the motor housing molded part 5 and improves the vibration detection data. In this process, the air supply equipment does not need to supply air again, that is, only one gas supply is needed to complete the vibration work of the motor housing molded part 5 twice, so as to avoid the subsequent motor housing molded part 5 being difficult to demould and the occurrence of defects.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
