[0002] In the prior art, in order to reduce the overall volume of the ultrasonic gas meter, the base meter housing is divided into two parts along the diagonal line so that the separated housings can have a large enough area to install the display screen. Figure 1 As shown, by presetting a groove in the same shape as the ultrasonic base shell on the lower die, and presetting a convex block in the same shape as the ultrasonic base shell on the front die moving block, the steel plate is pressed onto the lower die by the front die pressing block, and the steel plate can be pressed into the shape required by the design by pressing the front die moving block downward. However, when the front die moving block starts to press the steel plate, the tangential stress of the steel plate is too large, causing the material to lose stability, resulting in uneven wrinkles along the edge of the product, and the manufactured shell will easily form wrinkles 27 at the corners, affecting the flatness of the surface of the base surface, such as Figure 2 shown.

The first module 1 also includes a connecting surface 11 connecting the first surface 4 and the second surface 5, and the connecting surface 11 is a smooth and straight surface. The two half-pieces of the ultrasonic base surface shell are arranged at intervals by reserving the connecting surface, which is convenient for segmentation. The first module 1 also includes a third surface 15 and a fourth surface 16 on the side facing the second module 2, the third surface 15 is smoothly connected to the first surface 4, the fourth surface 16 is smoothly connected to the second surface 5, the angle between the third surface 15 and the first surface 4 is greater than or equal to 90 degrees, and the angle between the fourth surface 16 and the second surface 5 is greater than or equal to 90 degrees. The adjacent inner side walls of the first groove 6 are perpendicular to each other. In order to make the corners of the shell after molding smoothly transition and prevent large burrs from forming on the edge of the shell, the connection between the inner side walls of the first groove 6 is provided with rounded corners.

[0036] The second module 2 can move back and forth between positions away from and close to the first module 1. The second module 2 includes a punching channel 8 formed by a plurality of side walls and a first side wall 9 and a second side wall 10 arranged opposite to each other. The first side wall 9 and the second side wall 10 can cooperate with the first surface 4 and / or the second surface 5 at one end close to the first module 1. The second module 2 also includes a first positioning surface 17 and a second positioning surface 18. The first positioning surface 17 cooperates with at least a portion of the third surface 15, and the second positioning surface 18 cooperates with at least a portion of the fourth surface 16.

[0037] The third module 3 can move back and forth along the punching channel 8 between the position away from and close to the first module 1. The third module 3 includes a punch head. The side of the punch head facing the first module 1 is perpendicular to the moving direction of the third module 3. When the third module 3 cooperates with the first module 1, the end of the punch head close to the first module 1 completely fills the first groove 6 and the second groove 7. The side of the punch head facing the first module 1 includes a first wall surface 12, a second wall surface 13, and a connecting wall surface 14 connecting the first wall surface 12 and the second wall surface 13. When the third module 3 cooperates with the first module 1, the first wall surface 12 cooperates with a part of the wall surface forming the first groove 6, the second wall surface 13 cooperates with a part of the wall surface forming the second groove 7, and the connecting wall surface 14 cooperates with the connecting surface 11. The third module 3 also includes a first plane 19 and a second plane 20. The first plane 19 and the second plane 20 are located in the same horizontal plane or are arranged in parallel. When the third module 3 cooperates with the first module 1, the first plane 19 cooperates with at least a part of the third surface 15, and the second plane 20 cooperates with at least a part of the fourth surface 16. The punch head further includes a third wall surface 21 and a fourth wall surface 22, wherein the third wall surface 21 is connected to the first wall surface 12, the fourth wall surface 22 is connected to the second wall surface 13, the third wall surface 21 is connected to the first plane 19, the fourth wall surface 22 is connected to the second plane 20, the third wall surface 21 cooperates with a part of the wall surface forming the first groove 6, and the fourth wall surface 22 cooperates with a part of the wall surface forming the second groove 7. The third module 3 further includes a third plane 23 and a fourth plane 24, wherein the third plane 23 is connected to the first wall surface 12, the angle between the third plane 23 and the first wall surface 12 is greater than or equal to 90 degrees, the fourth plane 24 is connected to the second wall surface 13, the angle between the fourth plane 24 and the second wall surface 13 is greater than or equal to 90 degrees, the third plane 23 cooperates with a part of the first surface 4, and the fourth plane 24 cooperates with a part of the second surface 5.

[0038] When the ultrasonic base housing 26 is manufactured by stamping, the flat steel plate 25 is placed on the third surface 15 and the fourth surface 16 on the upper side of the first module 1, the first positioning surface 17 cooperates with the third surface 15, and the second positioning surface 18 cooperates with the fourth surface 16, so that the second module 2 and the first module 1 abut against each other, so that the steel plate 25 is stably supported above the first groove 6 and the second groove 7, and the steel plate 25 is parallel to the bottom surface of the first groove 6 and the bottom surface of the second groove 7. The stability of the steel plate 25 is improved when the third module 3 moves, the steel plate is prevented from sliding, and the integrity of the final shape of the steel plate is ensured. By pressing the third module 3 downward toward the first module 1, since the punch head of the third module 3 is adapted to the shape of the first groove 6 and the second groove 7, the side of the punch head facing the forming groove is parallel to the bottom surface of the first groove 6 and the second groove 7, and since the inner side surface of the forming groove can be perpendicular to the side surface of the forming groove, during the movement of the third module 3 toward the first module 1, the outer side of the punch head can always fit with the inner side surface of the first groove 6 and the second groove 7, and the first wall surface 12 and the second wall surface 13 of the punch head always fit with the entire steel plate 25, ensuring that during the forming process of the steel plate 25, wrinkles 27 will not appear on the formed product due to the existence of suspended areas. Figure 4 As shown, after stamping, two half pieces of ultrasonic base meter shell 26 can be obtained, which can be cut between the two ultrasonic base meter half shells. By forming two half pieces of ultrasonic base meter shell 26 at one time, there is no hanging area in the steel plate 25 during stamping, which avoids the generation of wrinkles 27 after the shell is formed, and ensures the accuracy of ultrasonic base meter measurement.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
