According to statistics from the inventors, it usually takes more than 2 minutes to complete the processing of a sensor housing. In other words, the efficiency of machining sensor housings is very slow. Summary of the invention

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can be implemented in many other ways different from the description, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0046] The present invention discloses a stamping die system for preparing a sensor housing, such as Figures 1 to 4 As shown, it includes a feeding mechanism 1 , a stamping mechanism 2 for stamping a material (ie, a semi-finished sensor housing) and a pushing mechanism 3 for pushing the material to the stamping mechanism 2 .

[0047] The feeding mechanism 1 includes a vibration plate 11 for holding materials, and a feeding channel 12, which are interconnected; the feeding channel 12 is connected to the pushing mechanism 3, and the vibration plate 11 provides vibration force to transport the material to the pushing mechanism 3 through the feeding channel 12, so that the pushing mechanism 3 pushes the material to the stamping position of the stamping mechanism 3; wherein the vibration plate 11 is connected to a vibration motor to obtain the corresponding vibration force, thereby realizing the loading of the vibration plate 11. Specifically, the vibration motor is arranged at the bottom of the vibration plate 11 (not shown in the drawings). Of course, the present invention is not limited to this.

[0048] When the pushing mechanism 3 pushes the material to the punching mechanism 2 (specifically, its punching position), the punching mechanism 2 punches the material into shape.

[0049] Based on the above structural design, the stamping die system described in the present invention can directly use the cold forming process of stamping to process the sensor housing, effectively avoiding technical problems such as frequent tool breakage in the machining process, and the processing efficiency is also significantly improved, which is conducive to reducing production costs.

[0050] As an example, Figures 1 to 4 As shown, the stamping die system also includes a solenoid valve 4, wherein the solenoid valve 4 is specifically a two-step two-way solenoid valve, of course, the present invention is not limited thereto; the solenoid valve 4 is connected to the stamping mechanism 2 and the pushing mechanism 3, so that when the pushing mechanism 3 pushes the material to the stamping mechanism 2, the stamping mechanism 2 immediately stamps the material. In other words, through the aforementioned structural design, the stamping structure 2 and the pushing mechanism 3 realize linkage work, so that when the material is located at the stamping position of the stamping structure 2, the stamping mechanism 2 can just stamp the material.

[0051] In the above embodiment, if Figures 1 to 4 As shown, specifically, the pushing mechanism 3 includes a pushing block 31, a cylinder 32, and a cylinder fixing frame 33 for fixing the cylinder 32; the cylinder 32 is connected to the solenoid valve 4, and the cylinder 32 is connected to the pushing block 31 to provide driving force therefor, so that the pushing block 31 pushes the material to the stamping mechanism 2; the solenoid valve 4 is also fixedly arranged on the cylinder fixing frame 33, so that the entire system structure is more compact.

[0052] In the above embodiment, specifically, Figures 1 to 4 As shown, the punching mechanism 2 includes a punching needle 21 for punching the material, a punching cross bar 22 with a square cross section, a punching vertical bar 23, a punching plate 24, a punching head 25 connected to the solenoid valve 4, an upper template 26, a male top plate 27, an upper pad 28, a fixed male plate 29, a stripping plate 210, a plurality of connecting screws 211, a lower template 212, a concave template 213, and a punching machine frame 224; because the punching head 22 is connected to the solenoid valve 4, the cylinder 32 and the punching head 22 are also linked;

[0053] A square through hole 251 is horizontally provided on the punch head 25, and the punching cross bar 22 is movably inserted into the square through hole 251; a first through hole 252 communicating with the square through hole 251 is vertically provided at the bottom of the punch head 25;

[0054] A second through hole 261 is vertically provided on the upper template 26, a third through hole 271 for accommodating the punching plate 24 is vertically provided on the male top plate 27, a plurality of fourth through holes 281 are vertically provided on the upper pad plate 28, a fifth through hole 291 and a plurality of sixth through holes 292 are vertically provided on the male fixing plate 29, and a seventh through hole 2101 and a plurality of screw holes 2102 are vertically provided on the stripping plate 210;

[0055] The punch head 25, the upper template 26, the male top plate 27, the upper pad 28, and the fixed male plate 29 are stacked and fixedly arranged from top to bottom. In this embodiment, Figure 1 , 2 As shown, the connection between the upper template 26 and the male top plate 27, and the connection between the upper pad 28 and the fixed male plate 29 are all connected by screws, while the connection between the punch head 25 and the upper template 26, and the connection between the male top plate 27 and the upper pad 28 are connected by welding, but it should be noted that the present invention is not limited to this; each connecting screw 211 is respectively and sequentially movably penetrates each fourth through hole 281 and each sixth through hole 292 and is respectively matched and fixedly connected with each screw hole 2102; one end of the punching vertical rod 23 is movably penetrated through the first through hole 252 and can be pushed to the bottom of the punching cross rod 22, and the other end is movably penetrated through the second through hole 261 and the third through hole 271 in turn and can be pushed to each connecting screw 211 through the punching plate 23;

[0056] The punching needle 21 is fixed vertically on the upper pad 28, based on which the punching needle 21 can obtain the driving force for moving up and down from the punch head 25; the punching needle 21 moves through the fifth through hole 291 and the seventh through hole 2101 in sequence. In addition, in order to prevent the punching needle 21 from being interfered with by the lower template 212 when the punching needle 21 moves upward with the punch head 21, which may easily cause the punching needle 21 to be pulled off, a groove 294 is provided at the position of the fifth through hole 291 on the upper surface of the fixed plate 29, and a horizontal hole is provided horizontally at the position of the punching needle 21 adjacent to the upper pad 28, and then a pin 226 is used to pass through the horizontal hole and the pin 226 is set in the groove 294.

[0057] A limit adjustment device 223 is provided on the punch frame 224, and the limit adjustment device 223 is located in the vertical moving direction of the punching cross bar 22 and above the punching cross bar 22; when the punch head 22 moves upward, the limit adjustment device 223 hits the punching cross bar 22 to make it move in the opposite direction, and through mechanical transmission, the upper pad 28 and the stripper plate 210 move relative to each other, so that the finished material at the end of the punch needle 21 is pushed down by the stripper plate 210;

[0058] The lower mold plate 212 is disposed on the concave mold plate 213 , and the push block 31 pushes the material onto the lower mold plate 212 for stamping and forming.

[0059] In this embodiment, the number of the connecting screws 211 is 3, and accordingly, the number of the fourth through holes 281, the sixth through holes 292, and the screw holes 2102 are also 3, but the present invention is not limited thereto, and it can also be set to other numbers.

[0060] In the above embodiment, more specifically, Figure 1 , 2 As shown in , 4, the stamping mechanism 2 also includes a plurality of first guide posts 214 and a plurality of first guide sleeves 215; each first guide post 214 is vertically arranged at the lower part of the upper pad 28; the fixed plate 29 is provided with a plurality of eighth through holes 293 for each first guide post 214 to move through, and the material stripping plate 210 is provided with a plurality of ninth through holes 2103 for each first guide post 214 to move through; each first guide sleeve 215 is vertically arranged on the lower template 212, and each first guide sleeve 215 is matched with each first guide post 214 one by one. Based on the aforementioned structural design, it can be ensured that the punching needle 21 will not be laterally offset when it moves down to stamp the material, which is beneficial to improving the stamping quality of the product. In this embodiment, the number of the first guide post 214, the eighth through hole 293, the ninth through hole 2103, and the first guide sleeve 215 is 4, and they are evenly distributed at the four corners of the components where they are located, but the present invention is not limited to this.

[0061] In the above embodiment, more specifically, Figure 1 , 2 4, the stamping mechanism 2 also includes a lower die frame 216, a lower pad 217, a spring 218, and a top block 219; the lower die frame 216 and the lower pad 217 are stacked in sequence from bottom to top at the lower part of the concave template 213, wherein, in this embodiment, as Figure 1 , 2 As shown, the connection between the lower mold frame 216 and the lower pad 217 is screwed, but the present invention is not limited to this. For example, they can be directly connected by welding, etc.; the spring 218 is vertically arranged on the upper part of the lower mold frame 216, and the lower pad 217 is vertically provided with a tenth through hole 2171 for the spring 218 to movably pass through; the ejecting block 219 is arranged at the upper end of the spring 218, and the concave mold plate 213 is provided with an eleventh through hole 2131 for the ejecting block 219 to movably pass through, and the stamping position of the lower mold plate 212 is provided with a twelfth through hole 2121 for the ejecting block 219 to movably pass through. Based on the aforementioned structural design, when the material is stamped, the ejection block 219 is pressurized, causing the spring 218 to compress; when the finished product is about to follow the punch needle 21 to leave the stamping position of the lower template 212, the reverse elastic force of the spring acts on the ejection block 219, causing the ejection block 219 to eject the finished product from the stamping position of the lower template 212, so as to ensure that the finished product is not stuck by the lower template 212 as much as possible, which is conducive to ensuring the continuity of production.

[0062] In the above embodiment, more specifically, Figure 1 , 2 As shown in , 4, the stamping mechanism 2 also includes a plurality of second guide pillars 220 and a plurality of second guide sleeves 221; each second guide pillar 220 is vertically arranged on the upper part of the lower mold frame 216, the lower pad 217 is provided with a plurality of thirteenth through holes 2172 for each second guide pillar 220 to movably pass through, and the male top plate 27 is provided with a plurality of fourteenth through holes 272 for each second guide pillar 220 to movably pass through; each second guide sleeve 221 is arranged at the bottom of the upper mold plate 26, each second guide sleeve 221 and each second guide pillar 220 are matched one by one, and each second guide pillar 220 is covered with a protective sleeve 225 to protect each second guide pillar 220 from damage. Based on the design of the above structure, not only can the upper template 26 and the lower template 212 be accurately aligned, which is very beneficial to improving the stamping quality of the product, but also, through the cooperation of the second guide column 220 and the second guide sleeve 221, the upper template 26 (including the male top plate 27) can have a certain shock-absorbing effect when it moves down for stamping, which is beneficial to improving the reliability of the use of the stamping die system. In this embodiment, the number of the second guide column 220, the thirteenth through hole 2172, the fourteenth through hole 272, and the second guide sleeve 212 are all 2, which are respectively located at the diagonal positions of the respective components. Correspondingly, the number of the protective sleeve 225 is also 2, so that while ensuring the accurate alignment of the upper template 26 and the lower template 212, the manufacturing raw materials of the stamping die system can be effectively saved, which is beneficial to saving the equipment manufacturing cost, but the present invention is not limited to this.

[0063] In the above embodiment, if Figures 1 to 4 As shown, a blowing part 222 is also provided on the stripping plate 210; the blowing part 222 is connected to the solenoid valve 4, and the cylinder 32, the punch head 25, and the blowing part 222 are linked under the regulation of the solenoid valve 4, so that when the finished material at the end of the punch needle 21 is pushed down by the stripping plate 210, the finished material is immediately blown away from the stamping mechanism 2 and enters the finished product storage device located on one side of the stamping die system.

[0064] In the above embodiment, if Figures 1 to 4 As shown, the push mechanism 3 also includes a transverse positioning block 34 and a longitudinal positioning block 35; the transverse positioning block 34 is arranged on both sides of the moving direction of the push block 31, and is used to limit the lateral swing of the push block 31 to ensure that the material is accurately pushed to the stamping position of the stamping mechanism 2, which is beneficial to improving the stamping quality of the product; the longitudinal positioning block 35 is arranged on the lower template 212 (in this embodiment, as shown in FIG. Figure 1 As shown, the longitudinal positioning block 35 is connected to the lower template 212 by means of screws, but the present invention is not limited thereto), which is used to limit the material from deviating from the stamping position of the lower template 212, and is also beneficial to improving the stamping quality of the product.

[0065] In the above embodiment, if Figure 1 , 2 As shown in Figures 4 and 5, the lower mold plate 212 is provided with an oil nozzle inlet 2122; the oil tank (not shown in the figures) is connected to the stamping position of the lower mold plate 212 through the oil nozzle inlet 2122. During the stamping process of the material, the lubricating oil is injected through the oil nozzle inlet 2122, which can effectively reduce the heat generated by the material during the stamping process.

[0066] To facilitate a better understanding of the present invention, the working principle of the stamping die system described in the above embodiment is described as follows:

[0067] like Figures 1 to 4 As shown, the solenoid valve 4 (specifically a two-step two-way solenoid valve) is connected to the cylinder 32, the punch head 26, and the blowing part 222, and they can be connected through an air pipe; more specifically, one interface of the solenoid valve 4 is connected to the upward stop point of the punch head 26, and the other interface is connected to the downward stop point of the punch head 26;

[0068] Under the regulation of the solenoid valve 4, when the punch head 26 moves downward, the cylinder 32 drives the push block 31 to move forward and pushes the material delivered by the feeding mechanism 1 to the punching position of the lower template 212, so that the punch needle 21 punches and forms the material. At this time, the solenoid valve 4 controls the blowing part 222 not to work;

[0069] After the material is stamped and formed, the punch head 26 moves upward, and under the regulation of the solenoid valve 4, the cylinder 32 drives the push block 31 to retract, so that the feeding mechanism 1 can convey the next material to the push mechanism 3; moreover, when the punch head 26 moves upward, the punching cross bar 22 is hit by the limit adjustment device 223 located on the punch frame 224, causing the punching cross bar 22 to move in the opposite direction, thereby causing the upper pad 28 (including the punch needle 21) and the stripping plate 210 to move relative to each other, and then the finished product stuck at the end of the punch needle 21 is pushed and dropped by the stripping plate 210, and at this time the solenoid valve 4 starts the blowing part 222 to work to blow out the fallen finished product, thereby completing the preparation of a finished sensor housing; this cycle is repeated.

It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work.
