[0033] See also Figures 1 to 13The present embodiment provides a spring forming mechanism, including a fixed panel 1, a wire feeding assembly 2 and a horizontal tool holder module 3 are provided on the left side of the fixed panel 1, a vertical tool holder module 4 is provided on the upper side of the fixed panel 1, a wire gauge assembly 5 is provided on the lower side of the fixed panel 1, and a spring forming space 6 is provided in the middle of the fixed panel 1; the wire feeding assembly 2 can convey the steel wire 7 to the right to the spring forming space 6, and the wire gauge assembly 5 can roll the steel wire 7 in the spring forming space 6 into a product spring 8; the horizontal tool holder module 3 and the vertical tool holder module 4 both include modules The slide 9 and the module knife seat 901 arranged on the module slide 9, the module knife seat 901 can slide relative to the module slide 9 toward the spring forming space 6, the module knife seat 901 is provided with a module tool 902, and the module tool 902 can be moved forward and backward and locked relative to the module knife seat 901; one of the horizontal knife holder module 3 and the vertical knife holder module 4 can support the hook 801 of the product spring 8 through the module tool 902, and the other can move the hook 801 of the product spring 8 through the module tool 902. Function: (1) A wire feeding assembly and a horizontal knife holder module are arranged on the left side of the fixed panel, a vertical knife holder module is arranged on the upper side of the fixed panel, a wire gauge assembly is arranged on the lower side of the fixed panel, and a spring forming space is arranged in the middle of the fixed panel; the wire feeding assembly can transport the steel wire to the right to the spring forming space, and the wire gauge assembly can roll the steel wire in the spring forming space into a product spring. Therefore, in actual production, the wire feeding assembly can be used to convey the steel wire to the right to the wire gauge assembly for winding into the main coil part and the hook coil part of the product spring. (2) The horizontal tool holder module and the vertical tool holder module both include a module slide and a module knife seat arranged on the module slide. The module knife seat can slide toward the spring forming space relative to the module slide. The module knife seat is provided with a module tool. The module tool can be moved forward and backward and locked relative to the module tool seat. One of the horizontal tool holder module and the vertical tool holder module can support the hook of the product spring through the module tool, and the other can move the hook of the product spring through the module tool. Therefore, in actual production, the module tool of the vertical tool holder module can be locked relative to the module tool holder in advance, and then when working, the module tool of the vertical tool holder module is used to move downward to hold the hook of the product spring, and then the module tool of the horizontal tool holder module is used to move to the right and move the hook of the product spring backward, so that the hook of the product spring is perpendicular to the main winding part of the product spring, and finally, the horizontal tool holder module and the vertical tool holder module are reset, and the product spring is formed as a whole, and the production cycle is repeated. It can be seen that the utility model can be processed and formed at one time when the main winding part, the hook winding part and the hook are moved by setting the horizontal tool holder module and the vertical tool holder module, thereby improving production efficiency.

[0034] Specifically, one end of the module tool 902 close to the spring forming space 6 passes over the module tool seat 901, the middle part of the module tool 902 is rotatably connected to the module tool seat 901, and the end of the module tool 902 away from the spring forming space 6 is connected to the module tool seat 901 through a reset spring 903 and is provided with a guide wheel 904. A guide rod 905 extending toward the spring forming space 6 and inclined in the front and rear directions is detachably installed on one side of the module slide 9, and the guide wheel 904 is guided and cooperated with the guide rod 905 so that the module tool 902 can be moved back and forth when reciprocating along the trajectory of the module slide 9. Function: In actual operation, (1) the horizontal tool holder module part: the guide rod 905 can be pre-set to gradually tilt from left to right and forward, so that the guide wheel 904 gradually moves forward along the guide rod 905 as the module tool holder 901 moves to the right. At this time, the module tool 902 rotates and the right end swings backward, so that the right end of the module tool 902 can push the hook backward; and after the pushing is completed, the guide wheel 904 gradually moves backward along the guide rod 905 as the module tool holder 901 moves to the left (because the reset spring 903 has a reset elastic force that drives the left end of the module tool 902 backward). At this time, the module tool 902 rotates in the opposite direction and the right end swings forward to achieve reset. (2) Vertical tool holder module: The guide rod 905 can be disassembled in advance, so that under the reset elastic force of the reset spring 903 driving the top of the module cutter 902 backward, due to the lack of external interference, the module cutter 902 does not rotate during the downward movement of the module cutter seat 901. After moving to the right position, the bottom end of the module cutter 902 will support the hook 801 of the product spring 8 (to facilitate the hook to move backward), and after the hook is moved, the module cutter 902 will be reset upward with the module cutter seat 901. Of course, according to actual needs, the work of the horizontal tool holder module and the vertical tool holder module can also be reversed, and the corresponding guide rods 905 can be disassembled and assembled.

[0035] Specifically, a motor 906 is provided on the side of the module slide 9 away from the spring forming space 6, a reducer 907 is provided on the motor 906, a rotating disk 908 is provided on the reducer 907, the edge of the rotating disk 908 is movably connected to one end of a connecting rod 909, and the other end of the connecting rod 909 is movably connected to one end of the module knife seat 901 away from the spring forming space 6, so that the rotation of the rotating disk 908 can drive the module knife seat 901 to reciprocate toward the spring forming space 6. Function: Under the drive of the motor, the driving force drives the rotation of the rotating disk 908 through the reducer 907, and then the edge of the rotating disk 908 drives the left end of the connecting rod 909 to move in a circle, and the right end of the connecting rod 909 drives the module knife seat 901 of the horizontal tool holder module 3 to reciprocate left and right relative to the module slide 9.

[0036] Specifically, a cutter head 914 is provided on the module tool 902, and one end of the cutter head 914 close to the spring forming space 6 is connected to the module tool 902 through an adjusting screw 915, and one end of the cutter head 914 away from the spring forming space 6 is connected to the module tool 902 through a screw 911; a waist-shaped hole 910 is provided on the cutter head 914, and a screw head 912 of the screw 911 passes through the waist-shaped hole 910, and the middle part of the screw 911 passes through the edge of the offset wheel 913, so that the rotation of the screw 911 can drive the offset wheel 913 to rotate, and the rotation of the offset wheel 913 can drive the cutter head 914 to deflect left and right or up and down, and the end of the cutter head 914 close to the spring forming space 6 can support or move the hook 801 of the product spring 8. Function: Figure 7 As shown, taking the vertical tool holder module as an example, when the cutter head 914 needs to be adjusted left and right, the adjusting screw 915 can be loosened first, and then the screw 911 can be rotated left and right with a wrench or other tools, so that the position of the offset wheel 913 on the screw 911 will change, thereby utilizing the relatively protruding position of the offset wheel 913 to drive the cutter head 914 to rotate around the adjusting screw 915, so that the cutter head 914 can be adjusted left and right relative to the module tool 902, and after the adjustment is completed, the adjusting screw 915 can be tightened and fixed. Since the working principle of the left and right adjustment of the cutter head 914 of the horizontal tool holder module is the same, it will not be repeated here. Since the cutter head 914 deflects left and right or up and down, the tool can be fine-tuned left and right or up and down for different types of products.

[0037] Specifically, the wire feeding assembly 2 includes an upper wire feeding wheel 201 and a lower wire feeding wheel 202 distributed along the upper and lower sides, a head end wire plate 203 is provided on the left side between the upper wire feeding wheel 201 and the lower wire feeding wheel 202, and a terminal wire plate 204 is provided on the right side between the upper wire feeding wheel 201 and the lower wire feeding wheel 202. The steel wire 7 can pass through the inside of the head end wire plate 203, between the upper wire feeding wheel 201 and the lower wire feeding wheel 202, and inside the terminal wire plate 204 to the right in sequence, and the upper wire feeding wheel 201 and the lower wire feeding wheel 202 can cooperate to drive the steel wire 7 to be transported to the right. Function: Through the driving effect of the upper wire feeding wheel 201 and the lower wire feeding wheel 202, and the guiding effect of the head end wire plate 203 and the terminal wire plate 204, the steel wire 7 is convenient to move to the right, and the upper wire feeding wheel 201 can be used as a driven wheel, and the lower wire feeding wheel 202 can rotate under the drive of the motor, so as to more conveniently drive the steel wire 4.

[0038] Specifically, a push block 10 that can push the product spring 8 outward is provided on the terminal wire plate 204, and a cutter assembly 11 is provided above the terminal wire plate 204. The cutter of the cutter assembly 11 can cooperate with the push block 10 to cut the connection point between the steel wire 7 and the product spring 8. Function: Through the setting of the cutter assembly 11, the cutter can cooperate with the push block 10 to cut the connection point between the steel wire 7 and the product spring 8, and the push block 10 can push the cut product spring 8 backward, so that the subsequent robot hand can clamp the product spring 8. Since the cutter and the push block 10 and other components are conventional components for spring production, they will not be described in detail here.

[0039] Specifically, a wire feeding wheel spring pressure adjusting part 12 is provided above the upper wire feeding wheel 201, and a movable space 1201 is provided in the middle of the wire feeding wheel spring pressure adjusting part 12, and an upper and lower movable plates 1202 are provided inside the movable space 1201, and a pressure spring 1203 is provided between the two movable plates 1202; the bottom end of the lower movable plate 1202 passes through the lower side wall of the movable space 1201 and is rotatably connected to the upper wire feeding wheel 201, and the top end of the upper movable plate 1202 passes through the upper side wall of the movable space 1201 and is connected to the movable column 1204, and a rotating groove 1205 is provided above the wire feeding wheel spring pressure adjusting part 12, and the rotating groove 1205 is rotatably connected to the rotating rod 1206, and the rotating rod 1206 can press the movable column 1204 downward when it rotates. Function: When the steel wire 7 needs to be passed through the gap between the upper wire feeding wheel 201 and the lower wire feeding wheel 202, the rotating rod 1206 can be rotated to a horizontal state first. At this time, the rotating rod 1206 no longer presses the movable column 1204, and the pressure spring 1203 is reset upward. Then, the upper wire feeding wheel 201 is no longer subjected to the large clamping force transmitted by the movable plate 1202, so that the steel wire 7 can easily pass through the gap between the upper wire feeding wheel 201 and the lower wire feeding wheel 202. When the steel wire 7 has passed through the upper wire feeding wheel 201 and the lower wire feeding wheel 202, the rotating rod 1206 is rotated to a vertical state, at which time the rotating rod 1206 presses the movable column 1204 downward, and then the pressure spring 1203 is compressed downward, and the upper wire feeding wheel 201 is again subjected to a large amount of pressing force from the movable plate 1202 and is in a close contact state with the lower wire feeding wheel 202, and the close contact state facilitates the upper wire feeding wheel 201 and the lower wire feeding wheel 202 to transport the steel wire 7. The upper wire feeding wheel 201 and the lower wire feeding wheel 202 can be tightened or loosened by rotating the rotating rod 1206, which is very convenient.

[0040] Specifically, the wire gauge assembly 5 includes a wire gauge slide 501 and two wire gauge knife seats 502 distributed on the wire gauge slide 501 along the left and right sides. The wire gauge knife seats 502 can move up and down along the wire gauge slide 501; the top of the wire gauge knife seat 502 is detachably provided with a wire gauge cutter 503, which can move upward and roll the steel wire 7 in the spring forming space 6 into a product spring 8. Function: When it is necessary to make the main coil part and the hook coil part of the product spring, one of the wire gauge knife seats 502 can be used to carry the wire gauge cutter 503 to move up and down along the wire gauge slide 501. When the wire gauge cutter 503 moves upward, the wire gauge cutter 503 can make the steel wire 7 coil, and when the wire gauge cutter 503 moves downward, the steel wire 7 can output a straight line (because the wire gauge cutter 503 is a conventional component for making springs, it will not be described in detail here). By setting up two wire gauge tool holders 502 on the left and right, it is convenient to change the position of the wire gauge tool 503. On the other hand, when facing special processing needs, one of the wire gauge tool holders 502 can be installed with the wire gauge tool 503, and the other wire gauge tool holder 502 can be installed with the required tool to participate in the processing, such as making a hook with a folded angle, or using it as an auxiliary cutter, or holding up the product body to prevent shaking. Therefore, the original single wire gauge tool holder is changed to a double wire gauge tool holder, which enriches the use scenarios, improves the adaptability, and is flexible in application.

[0041] Specifically, a main shaft 504 extending forward and backward and rotatable is provided at the lower left side of the wire gauge slide 501, and two rotating plates 505 distributed forward and backward are detachably mounted on the main shaft 504, and a protrusion 506 is provided on the edge of the rotating plate 505; a rotating shaft 507 is provided below the main shaft 504, and two rotating arms 508 distributed forward and backward are rotatably provided on the rotating shaft 507, and the left end of the rotating arm 508 can be pressed down with the protrusion 506 of the rotating plate 505, and the right end of the rotating arm 508 is movably connected to the bottom end of the vertical rod 509, and the top end of the vertical rod 509 is movably connected to the bottom end of the wire gauge knife seat 502; the bottom end of the wire gauge knife seat 502 is connected to the top end of the vertical spring 510, and the bottom end of the vertical spring 510 is connected and fixed to the fixed panel 1. Function: With the rotation of the main shaft 504, the two rotating pieces 505 can also rotate accordingly. Since the protruding piece 506 will form a downward pressure with the left end of the rotating arm 508 during the rotation of the rotating piece 505, the rotating arm 508 will rotate around the rotating axis 507, and then the right end of the rotating arm 508 will push the vertical rod 509 upward, and the vertical rod 509 will push the wire gauge cutter seat 502 upward, so that the wire gauge cutter 503 can participate in the production of the product spring. After the production is completed, the bottom end of the vertical rod 509 and the right end of the rotating arm 508 will be reset downward under the action of the vertical spring 510 (because the protruding piece 506 has been separated from the left end of the rotating arm 508 at this time), and the vertical rod 509 will move downward with the wire gauge cutter seat 502. In this cycle, the reciprocating up and down motion of the wire gauge cutter seat 502 can be realized. Since the two rotating pieces 505 correspond to the two rotating arms 508 , the two vertical rods 509 , and the two vertical springs 510 , respectively, when there is no need to drive one of the wire gauge knife seats 502 to move upward, one of the rotating pieces 505 can be disassembled.

[0042] Specifically, a plurality of screw holes 511 are provided on the edge of the end face of the main shaft 504 and are distributed in a circumferential direction. The rotating piece 505 can rotate around the main shaft 504, and the screw holes 511 can cooperate with a plurality of screws 512 to lock and fix the rotating piece 505 on the main shaft 504; the top of the wire gauge slide 501 is rotatably connected to the fixed panel 1, and a slide left and right adjustment block 13 is provided above the main shaft 504. The internal thread of the slide left and right adjustment block 13 is connected with an adjustment rod 1301 extending left and right, and the left end of the adjustment rod 1301 is connected to the rotating wheel 1302, and the right end of the adjustment rod 1301 abuts against the left side wall of the wire gauge slide 501, so that the left and right movement of the adjustment rod 1301 can adjust the wire gauge slide 501 left and right. Function: Two or three screw holes 511 can cooperate with screws 512 to lock and fix one rotating piece 505 on the main shaft 504, and the other two or three screw holes 511 can cooperate with screws 512 to lock and fix another rotating piece 505 on the main shaft 504. Since the screws used are different, the corresponding screws can be screwed as needed to rotate, disassemble, fix, etc. the corresponding rotating piece 505. When it is necessary to adjust the wire gauge slide 501 left and right (the left and right adjustment of the wire gauge slide 501 is convenient for making product springs of different diameters), the rotating wheel 1302 can be screwed, so that the adjustment rod 1301 moves to the right and pushes the bottom end of the wire gauge slide 501 to the right. At this time, the wire gauge slide 501 is adjusted left and right accordingly by rotation. When it is necessary to reset, the rotating wheel 1302 is screwed in the opposite direction, so that the adjustment rod 1301 moves to the left, and the wire gauge slide 501 is reset by rotation.

[0043] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the protection scope of the present invention.
