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] Specific examples are given below.

[0027] See also Figure 1 - Figure 6The utility model provides a sheet metal mold with size adjustment function, including a seat 1; a servo motor 11 is fixedly connected to the outer wall of the mold base 1; a forward threaded rod 12 is fixedly connected to the output end of the servo motor 11; a first fixing plate 13 is threadedly connected to the outer wall of the forward threaded rod 12; the first fixing plate 13 is in sliding contact with the mold base 1; a support block 14 is rotatably connected to the outer wall of the forward threaded rod 12; a reverse threaded rod 15 is inserted into the side wall of the forward threaded rod 12; the reverse threaded rod 15 is in contact with the support block 14; the reverse threaded rod 15 can be detached from the support block 14; a fixing ring 16 is fixedly connected to the outer wall of the reverse threaded rod 15; the inner wall of the mold base 1 The wall is fixed with a limit plate 17; the limit plate 17 is in sliding contact with the reverse threaded rod 15; the outer wall of the reverse threaded rod 15 is threadedly connected with a second fixed plate 18; the inner wall of the mold base 1 is fixed with a support ring 19; the outer wall of the reverse threaded rod 15 is fixed with a connecting ring 10; the outer wall of the reverse threaded rod 15 is threadedly connected with a movable handle 101; the top of the outer wall of the mold base 1 is fixed with a support frame 102; the inner wall of the support frame 102 is slidably connected with a limit clamping plate 103; the limit clamping plate 103 is in contact with the connecting ring 10; the outer wall of the limit clamping plate 103 is fixed with a spring 104; the top of the outer wall of the spring 104 is fixed with the support frame 102. Start the servo motor 11. When the reverse threaded rod 15 is plugged into the forward threaded rod 12, the limit clamp 103 limits the connecting ring 10 in a fixed position, so that the reverse threaded rod 15 can rotate normally with the forward threaded rod 12. Pulling the limit clamp 103 can pull the reverse threaded rod 15 outward to move the fixing ring 16 to the position of the limit plate 17. At this time, the reverse threaded rod 15 is out of contact with the forward threaded rod 12. Due to the limitation of the limit plate 17, the reverse threaded rod 15 will not fall. At this time, only the forward threaded rod 12 rotates by itself. When the forward threaded rod 12 and the reverse threaded rod 15 rotate, the first fixing plate 13 and The second fixing plates 18 will move away from or towards each other to adjust the sheet metal parts to be processed and adjust the lengths of the bottom holes on both sides to control the shape of the bottom of the sheet metal parts when being processed. When both sides of an ordinary mold move toward the center at the same time, the processing position is related to the shape and diameter of the sheet metal parts and is difficult to adjust. By setting the forward threaded rod 12 and the reverse threaded rod 15, the center points of the first fixing plate 13 and the second fixing plate 18 are offset, so that the position of the sheet metal parts being processed is changed, and the edges and other positions can be processed, thereby increasing the practicability of the equipment and facilitating the staff to process special-shaped or sheet metal parts edges.

[0028] Further, such as Figure 1As shown, two pairs of fixed blocks 2 are fixedly connected to the top of the outer wall of the mold base 1; a slide bar 21 is fixedly connected to the side wall of the fixed block 2; a pair of support plates 22 are fixedly connected to the top of the outer wall of the mold base 1; a first threaded rod 23 is threadedly connected to the inner wall of the support plate 22; a third fixed plate 24 is fixedly connected to the outer wall of the first threaded rod 23; and the third fixed plate 24 is in sliding contact with the slide bar 21. The first threaded rod 23 is rotated to move the support plate 22, and at this time, the third fixed plate 24 is restricted by the slide bar 21, and the third fixed plate 24 will move stably. By setting the third fixed plate 24 and the first threaded rod 23, when the equipment encounters a larger sheet metal part, the equipment can be adjusted according to the actual situation to meet the needs of the staff for the use of the equipment and increase the practicality of the equipment.

[0029] Further, such as Figure 1 As shown, the outer wall of the first fixing plate 13 is provided with a contact plate 3; the outer wall of the contact plate 3 is rotatably connected with a second threaded rod 31; the outer wall of the second threaded rod 31 is fixedly connected with a turntable 32; the second threaded rod 31 penetrates the first fixing plate 13; the second threaded rod 31 is threadedly connected with the first fixing plate 13. The turntable 32 is rotated to move the contact plate 3 toward the second fixing plate 18, and the contact plate 3 replaces the first fixing plate 13 and the second fixing plate 18 to fix the sheet metal. When the equipment encounters a smaller sheet metal, the first fixing plate 13 and the second fixing plate 18 cannot contact the sheet metal through the contact plate 3, and the extended contact plate 3 can fill the gap between the two, so that when the equipment encounters a smaller part, the gap can be supplemented, thereby increasing the stability of the equipment.

[0030] Further, such as Figure 6 As shown, the outer wall of the first fixed plate 13 is fixedly connected with an annular brush plate 4; the inner wall of the annular brush plate 4 is fixedly connected with a plurality of cleaning bristles 41; the outer wall of the cleaning bristles 41 is in contact with the forward threaded rod 12. When the device is working, the forward threaded rod 12 will rotate, the first fixed plate 13 will continuously move above the forward threaded rod 12, the position where the forward threaded rod 12 contacts the first fixed plate 13 will change, and then the position of the cleaning bristles 41 will change, and the cleaning bristles 41 will clean the outer wall of the forward threaded rod 12. The cleaning bristles 41 are provided to increase the cleanliness of the surface of the forward threaded rod 12, and reduce the phenomenon of jamming and failure during the connection between the first fixed plate 13 and the forward threaded rod 12 due to dust and impurities adsorbed by the outer wall of the forward threaded rod 12.

[0031] Further, such as Figure 1As shown, the outer wall of the mold base 1 is fixedly connected with a placement box 5; the inner wall of the placement box 5 is provided with a groove; the inner groove of the placement box 5 is slightly larger than the movable handle 101. When the device is working, the movable handle 101 can be separated from the device, and the movable handle 101 is an important part of the device. The movable handle 101 is placed on the placement box 5, taken out when used, and placed back to the original position after use. The placement box 5 is set to reduce the probability of the movable handle 101 being lost, and it is convenient for the staff to store and use the movable handle 101.

[0032] Further, such as Figure 2 As shown, a plurality of sealing bristles 6 are fixedly connected to the inner side of the die base 1; the sealing bristles 6 do not contact the first fixing plate 13; the length of the sealing bristles 6 is greater than the diameter of the positive threaded rod 12. The sealing bristles 6 can fill the hole above the die base 1 from the inside, without affecting the effect of the hole on the sheet metal, making it difficult for dust and impurities generated by the sheet metal processing to directly enter the interior of the equipment, thereby reducing the probability of equipment jamming or equipment failure due to impurities.

[0033] Further, such as Figure 6 As shown, a plurality of balls 7 are provided on the outer side wall of the first fixing plate 13; the balls 7 rotate on the side wall of the first fixing plate 13; the balls 7 are in contact with the servo motor 11; the balls 7 cannot be separated from the first fixing plate 13. When the equipment is working, the first fixing plate 13 will slide with the mold base 1, and the sliding friction between the first fixing plate 13 and the mold base 1 is transformed into rolling friction by the provided balls 7, thereby increasing the smoothness of the first fixing plate 13 when it is running.

[0034] Working principle: Start the servo motor 11. When the reverse threaded rod 15 is plugged into the forward threaded rod 12, the limit clamp 103 limits the connecting ring 10 in a fixed position, so that the reverse threaded rod 15 can rotate normally with the forward threaded rod 12. Pull the limit clamp 103 to pull the reverse threaded rod 15 outward, so that the fixing ring 16 moves to the position of the limit plate 17. At this time, the reverse threaded rod 15 is out of contact with the forward threaded rod 12. Due to the limitation of the limit plate 17, the reverse threaded rod 15 will not fall off. At this time, only the forward threaded rod 12 rotates by itself. When the forward threaded rod 12 and the reverse threaded rod 15 rotate, the first fixed plate 13 and the second fixed plate 18 will move away from or approach each other. , adjust the sheet metal parts to be processed, adjust the lengths of the bottom holes on both sides, and then control the shape of the bottom of the sheet metal parts when being processed. When both sides of the ordinary mold move toward the center at the same time, the processing position is related to the shape and diameter of the sheet metal parts, which is difficult to adjust. By setting the forward threaded rod 12 and the reverse threaded rod 15, the center points fixed by the first fixing plate 13 and the second fixing plate 18 are offset, so that the position of the sheet metal parts being processed is changed, and the edges and other positions can be processed, which increases the practicality of the equipment and is convenient for the staff to process the edges of special-shaped or sheet metal parts. The first threaded rod 23 is rotated to move the support plate 22. At this time, the third fixing plate 24 is restricted by the sliding rod 21, and the third fixing plate 24 will be stable The third fixing plate 24 and the first threaded rod 23 are provided so that when the equipment encounters a larger sheet metal part, the equipment can be adjusted according to the actual situation to meet the needs of the staff for the use of the equipment and increase the practicality of the equipment. The turntable 32 is rotated to move the contact plate 3 toward the second fixing plate 18. The contact plate 3 replaces the first fixing plate 13 and the second fixing plate 18 to fix the sheet metal part. When the equipment encounters a smaller sheet metal part, the first fixing plate 13 and the second fixing plate 18 cannot contact the sheet metal part through the contact plate 3. The extended contact plate 3 can fill the gap between the two, so that when the equipment encounters a smaller part, the gap can be supplemented, thereby increasing the stability of the equipment. When the equipment is working, the forward threaded rod 12 will rotate, and the first fixed plate 13 will continuously move above the forward threaded rod 12. The contact position between the forward threaded rod 12 and the first fixed plate 13 will change, thereby changing the position of the cleaning bristles 41. The cleaning bristles 41 clean the outer wall of the forward threaded rod 12. The cleanliness of the surface of the forward threaded rod 12 is increased by setting the cleaning bristles 41, and the dust and impurities attached to the outer wall of the forward threaded rod 12 cause the first fixed plate 13 to be stuck and malfunction during the connection between the forward threaded rod 12. When the equipment is working, the movable handle 101 can be detached from the equipment, and the movable handle 101 is an important part of the equipment.The movable handle 101 is placed on the placement box 5, taken out when used, and placed back in place after use. The placement box 5 is set to reduce the probability of losing the movable handle 101, which is convenient for the staff to store and use the movable handle 101. The sealing bristles 6 can fill the holes above the mold base 1 from the inside without affecting the effect of the holes on the sheet metal, making it difficult for dust and impurities generated by the sheet metal processing to directly enter the interior of the equipment, thereby reducing the probability of equipment jamming or equipment failure due to impurities. When the equipment is working, the first fixed plate 13 will slide with the mold base 1, and the sliding friction between the first fixed plate 13 and the mold base 1 will be converted into rolling friction through the set ball 7, thereby increasing the smoothness of the first fixed plate 13 during operation.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
