[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1-3 The utility model provides a technical solution: a forming device for making a long arc sheet metal of an image measuring instrument, comprising a lower template 1 and an upper template 2, a forming mechanism 5 and a guide mechanism 4 are respectively arranged between the lower template 1 and the upper template 2, a plurality of first positioning holes 3 are opened in the upper template 2, and a plurality of third positioning holes 6 are opened on the top of the lower template 1;

[0027] The forming mechanism 5 includes a buffer pad 501 and a lower mold 503. The top of the buffer pad 501 is connected to the bottom of the upper template 2, and the bottom of the lower mold 503 is connected to the top of the lower template 1. The bottom of the buffer pad 501 is connected with an upper mold 502. Two second positioning holes 504 are opened in the lower mold 503. A through hole 506 is opened on one side of the second positioning hole 504. A positioning pin 505 is slidably connected to the inner wall of the second positioning hole 504. One end of the positioning pin 505 extends outside the second positioning hole 504, and the other end of the positioning pin 505 extends into the through hole 506. The outer wall of the positioning pin 505 is slidably connected to the inner wall of the through hole 506. One end of the positioning pin 505 is connected with a second spring 507, and the other end of the second spring 507 is connected to the top of the lower template 1.

[0028] The specific implementation method is as follows: By setting the forming mechanism 5, the unfolded piece of the long-arc-shaped sheet metal connecting piece is placed between the upper mold 502 and the lower mold 503. By matching the positioning pin 505 with the two positioning holes reserved on the sheet metal unfolded piece, the sheet metal unfolded piece can be accurately positioned on the lower mold 503, so as to avoid shape differences during batch production. By pressing the upper template 2 to drive the buffer pad 501 and the upper mold 502 to move downward, the upper mold 502 can cooperate with the lower mold 503 to press the sheet metal unfolded piece, so that the sheet metal unfolded piece can obtain the required shape only through one pressing, which not only improves the production efficiency but also ensures the appearance. Since the shapes of the upper mold 502 and the lower mold 503 are fixed, the shapes of the batch-produced sheet metal connecting pieces will not be different, and any one can be selected during splicing, thus realizing the rapid forming of the sheet metal connecting piece, and the operation is simple and fast, greatly improving the production efficiency. Since the second spring 507 is installed at the lower part of the positioning pin 505, when the upper mold 502 and the lower mold 503 press the long-arc-shaped sheet metal connecting piece, the positioning pin 505 can contract into the second positioning hole 504 and the through hole 506 opened in the lower mold 503. By setting the buffer pad 501, since a large impact force is required for the forming of the sheet metal connecting piece, the buffer pad 501 can play a buffering role, so as to protect the upper mold 502 and the lower mold 503 and avoid damage to the upper mold 502, the lower mold 503 or the workpiece due to vibration, collision, etc.

[0029] The guiding mechanism 4 includes a plurality of ball bushings 401, a plurality of first limiting columns 404 and a plurality of second limiting columns 405. The outer wall of the ball bushing 401 is connected to the inner wall of the first positioning hole 3, and one side of the ball bushing 401 extends outside the first positioning hole 3. One side of the first limiting column 404 is connected to the bottom of the upper template 2, and one side of the second limiting column 405 is connected to the top of the lower template 1. A guide post 403 is slidably connected to the inner wall of the ball bushing 401. The outer wall of the guide post 403 is connected to the inner wall of the third positioning hole 6. A first spring 402 is sleeved outside the guide post 403, and both ends of the first spring 402 are respectively connected to one side of the ball bushing 401 and the top of the lower template 1.

[0030] The specific implementation method is as follows: by setting the guide mechanism 4, when the upper template 2 and the upper mold 502 move downward, the upper template 2 can drive the ball guide sleeve 401 to move downward along the guide column 403. Since the guide column 403 provides a guiding force for the upper template 2, it can prevent the upper mold 502 from tilting, rotating or deviating during the movement, and thus can accurately guide, thereby ensuring the stability and accuracy of the sheet metal connector forming, and at the same time, it can also balance the force on the forming device to avoid deviation or deformation between the upper mold 502 and the lower mold 503. During the downward movement of the ball guide sleeve 401, the balls in the ball guide sleeve 401 will roll on the surface of the guide column 403, thereby reducing friction and improving movement accuracy and stability. Through the setting of the first spring 402, when the ball guide sleeve 401 moves downward , the first spring 402 will be compressed by the pressure of the ball guide sleeve 401 and generate elastic force, thereby providing a buffer for the ball guide sleeve 401, and after the sheet metal connector is pressed and formed, the first spring 402 can release the elastic force to drive the upper template 2, the buffer pad 501, and the upper mold 502 to return to their original positions, thereby facilitating the removal of the formed sheet metal connector. By setting the first limiting column 404 and the second limiting column 405, the upper template 2 can drive the first limiting column 404 to move downward when moving downward, and the first limiting column 404 will be blocked by the second limiting column 405 after moving downward for a certain distance, thereby limiting the closing amount of the upper mold 502 and the lower mold 503, preventing the upper mold 502 and the lower mold 503 from excessively squeezing the sheet metal unfolded parts and affecting the pressing effect of the sheet metal unfolded parts.

[0031] Working principle: During use, place the unfolded part of the long-arc sheet metal connector between the upper die 502 and the lower die 503. Through the cooperation of the positioning pins 505 and two pre-reserved positioning holes on the sheet metal unfolded part, the sheet metal unfolded part can be accurately positioned on the lower die 503, thus avoiding shape differences during batch production. Then, by pressing the upper template 2, the buffer pad 501 and the upper die 502 can be driven to move downward together, so that the sheet metal unfolded part can be pressed through the cooperation of the upper die 502 and the lower die 503, and thus the sheet metal connector can be formed in one step. When the upper die 502 and the lower die 503 press the sheet metal connector, the positioning pins 505 will be pressured by the upper die 502 and contract into the second positioning hole 504 and the through hole 506 opened in the lower die 503, and drive the second spring 507 to compress, causing the second spring 507 to generate elastic force. After the sheet metal connector is pressed, the second spring 507 can release the elastic force to drive the positioning pins 505 to return upward to their original positions. When the upper template 2 and the upper die 502 move downward, the upper template 2 can drive the ball bushing 401 to move downward along the guide post 403. Since the guide post 403 provides a guiding force for the upper template 2, it can prevent the upper die 502 from tilting, rotating or shifting during movement. When the ball bushing 401 moves downward, the first spring 402 will be compressed by the pressure of the ball bushing 401 and generate elastic force, so as to provide a buffer for the ball bushing 401. And after the sheet metal connector is pressed and formed, the first spring 402 can release the elastic force to drive the upper template 2, the buffer pad 501 and the upper die 502 to return to their original positions, thus facilitating the removal of the formed sheet metal connector. When the upper template 2 moves downward, it can drive the first limit post 404 to move downward. After the first limit post 404 moves downward a certain distance, it will be blocked by the second limit post 405, so as to limit the closing amount of the upper die 502 and the lower die 503.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
