Description

Technical Field

[0001] This invention relates to the field of spring forming technology, specifically a fully automatic high-precision compression spring forming device. Background Technology

[0002] Compression springs are basic components widely used in industry and daily life, and are widely used in automobile manufacturing, precision machinery, electronic equipment and aerospace. Compression spring forming equipment is the main equipment used to manufacture compression springs. It achieves precise winding and forming of springs through specific mechanical structures and control systems.

[0003] According to the search, the existing patent number is 202423185594.6, which is a spiral cylindrical compression spring forming device. The device uses a drive motor to drive the connecting shaft and the mandrel to rotate, thereby winding the continuously fed cylinder onto the mandrel to form the spring. Finally, the spring is cut off by a cutting blade to complete the production of the compression spring.

[0004] However, the equipment lacks a feeding component during compression molding. After the springs are formed, workers need to manually disassemble and recycle them, which is cumbersome, time-consuming, and labor-intensive. Furthermore, most of the shearing components are fixed structures, making it difficult to flexibly adjust the shearing position according to the length requirements of springs of different specifications. At the same time, during the winding and shearing process, impurities such as oxide scale and metal shavings are generated on the surface of the steel wire. These shavings easily adhere to the surface of the finished springs or get stuck in the gaps between the springs. The formed springs usually need to undergo an additional cleaning process before entering the next stage, which not only increases the production process and equipment investment costs but also reduces the overall production efficiency.

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figure 1 and Figure 4As shown, the fully automatic high-precision compression spring forming device of the present invention includes a machine body 1, a forming mechanism 3 and a shearing component 2 installed on the machine body 1, a material guiding mechanism 5 for product feeding installed on the machine body 1, and a screening mechanism 6 for separating debris on the product installed at the bottom of the material guiding mechanism 5.

[0027] Specifically, such as Figure 1 As shown, the molding mechanism 3 includes a vertical plate 301, which is vertically slidably connected to the machine body 1. Two parallel cylinders 304 are mounted on the machine body 1, and the output shafts of the two cylinders 304 are respectively connected to one side of the vertical plate 301. A connecting shaft 303 is rotatably connected to the vertical plate 301. A drive motor 302 for driving and controlling the connecting shaft 303 is mounted on the other side of the vertical plate 301. The installation of the vertical plate 301 facilitates the installation of the drive motor 302 and the connecting shaft 303. The mechanism is driven by an external controller. The drive motor 302 is activated, which drives the connecting shaft 303 to rotate at a constant speed to form the spring. After forming to a specified length, the spring is sheared by the shearing component 2. During shearing, the cylinder 304 controls the vertical plate 301 to slide, so that the connecting shaft 303 is separated from the spring, making it easier for the spring to fall off. Finally, the cylinder 304 controls the vertical plate 301 to reset, so that the next spring can be produced. (For the working principle of compression spring forming and shearing component, please refer to patent number: 202423185594.6 A spiral cylindrical compression spring forming device.)

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the material guiding mechanism 5 includes a first guide plate 501 and a second guide plate 502. The first guide plate 501 and the second guide plate 502 are respectively installed on the opposite side of the shearing assembly 2 and the vertical plate 301 via support blocks 503. The opposite ends of the first guide plate 501 and the second guide plate 502 abut against each other. The first guide plate 501 and the second guide plate 502 are respectively located at the bottom of the connecting shaft 303, and the angle between the first guide plate 501, the second guide plate 502 and the top of the machine body 1 is 45 degrees. With the cooperation of the support block 503, it is convenient to install the first guide plate 501 and the second guide plate 502. The 45-degree angle between the first guide plate 501, the second guide plate 502 and the top of the machine body 1 facilitates the smooth discharge of material after the spring falls.

[0029] Specifically, such as Figure 5 As shown, the second guide plate 502 has a connecting groove 504 at one end near the first guide plate 501. One end of the first guide plate 501 is slidably connected to the inside of the connecting groove 504. Through the cooperation of the connecting groove 504, the first guide plate 501 and one end of the second guide plate 502 can slide, which makes it easier for the subsequent shearing assembly 2 to adjust its position and realize the production of springs of different models.

[0030] Specifically, such as Figure 1 and Figure 4As shown, the screening mechanism 6 includes a feeding plate 601. The feeding plate 601 is installed at the top edge of the machine body 1. The feeding plate 601 is at a 45-degree angle to the machine body 1. The feeding plate 601 is located at the bottom of the first guide plate 501 and the second guide plate 502. A screen 603 is installed on the feeding plate 601. The installation of the feeding plate 601 facilitates the reception of the springs led out by the first guide plate 501 and the second guide plate 502. Furthermore, the installation of the screen 603 on the feeding plate 601 facilitates the removal of debris falling from the springs, ensuring that the springs are clean after feeding and reducing wear.

[0031] Specifically, such as Figure 4 As shown, the feeding plate 601 has a "U"-shaped structure. Multiple equally spaced protrusions 604 are horizontally installed on the screen 603. A feeding hopper 602 corresponding to the screen 603 is installed at the bottom of the feeding plate 601. The bottom of the feeding hopper 602 extends to the bottom of the machine body 1. The "U"-shaped structure design helps to prevent the spring from rolling outward. The installation of the feeding hopper 602 facilitates the discharge and recycling of debris screened by the screen 603. The installation of the protrusions 604 helps to increase the deceleration and buffering effect, making the spring roll slowly on the screen 603. In addition, the protrusions 604 can also play a shaking role, making the debris fall off better.

[0032] Specifically, such as Figure 1 and Figure 2 As shown, the machine body 1 is equipped with an adjustment mechanism 4 for adjusting the position of the shearing component 2. The adjustment mechanism 4 includes a mounting base 401, which is fixedly connected to the machine body 1. The mounting base 401 has a movable groove 403. The bottom of the shearing component 2 is slidably connected to the inside of the movable groove 403. The shearing component 2 slides along the connecting shaft 303 with the mounting base 401 through the movable groove 403. The mounting base 401 is equipped with a drive component for controlling the precise movement of the shearing component 2. With the installation of the mounting base 401 and the cooperation of the movable groove 403, the shearing component 2 can slide on the mounting base 401, adjusting the position of the shearing component 2 and the connecting shaft 303, thereby realizing the shearing of springs of different sizes. This is beneficial for producing springs of different models. The drive component facilitates the precise adjustment of the position of the shearing component 2.

[0033] Specifically, such as Figure 3As shown, the drive assembly includes a lead screw 404 and a servo motor 402. The lead screw 404 is rotatably connected inside the movable slot 403. The lead screw 404 is threadedly connected to the bottom of the shearing assembly 2. The servo motor 402 is mounted on one end of the mounting base 401. The output shaft of the servo motor 402 is connected to one end of the lead screw 404 via a coupling. Through the installation of the lead screw 404, the lead screw 404 can drive the shearing assembly 2 to move precisely under the action of the thread. Through the installation of the servo motor 402, under the control of an external controller, the servo motor 402 drives and controls the lead screw 404, thereby enabling the lead screw 404 to control the position of the shearing assembly 2.

[0034] Specifically, such as Figure 1 and Figure 4 As shown, a vibration mechanism 7 is installed on the machine body 1 to support and vibrate the feeding plate 601 and the feeding hopper 602. The vibration mechanism 7 includes a fixed block 701, which is fixedly connected to the top edge of the machine body 1. The bottom of the feeding hopper 602 is slidably connected to the top of the fixed block 701. A slider 702 is slidably connected to the top of the fixed block 701 through multiple vibration springs 703. The top of the slider 702 is fixedly connected to the bottom of the feeding hopper 602. Multiple guide rods 704 are vertically fixedly connected to the side of the slider 702 near the vibration springs 703. One end of each guide rod 704 passes through the vibration springs 703 and the fixed block 701, respectively. The sliding connection, through the installation of the fixed block 701, facilitates the stable support of the hopper 602. Through the installation of the slider 702, with the cooperation of multiple shaking springs 703, the slider 702 and the top of the fixed block 701 can slide elastically. The slider 702 is fixedly connected to the bottom of the hopper 602, which facilitates the elastic sliding of the hopper 602 and the top of the fixed block 701, making it easier to shake the screen 603 on the discharge plate 601 and increase the screening effect. Through the installation of multiple guide rods 704, it facilitates the guidance and limitation between the slider 702 and the fixed block 701, so that the slider 702 slides smoothly on the fixed block 701 and will not detach.

[0035] Specifically, such as Figure 1 , Figure 8 , Figure 9 and Figure 10As shown, a control mechanism 8 for controlling the vibration of the unloading plate 601 is installed on one side of the upright plate 301. The control mechanism 8 includes a transmission rod 801. The transmission rod 801 is slidably connected to the side of the upright plate 301 near the unloading plate 601 via a connecting assembly. Multiple protrusions 808 are installed on the outer side of the end of the connecting shaft 303 near the upright plate 301. One end of the transmission rod 801 is located outside the connecting shaft 303, and an arc-shaped push plate 807 is installed on the other end of the transmission rod 801. A rotating shaft 804 is connected to the outer side of the unloading plate 601. One side of the push plate 807 is connected to the rotating shaft 804. The outer contact, through the cooperation of the connecting components, facilitates the sliding installation of the transmission rod 801 on the outer side of the upright plate 301, and the transmission rod 801 and the connecting components slide elastically. Through the installation of multiple protrusions 808, when the connecting shaft 303 rotates at a constant speed, the multiple protrusions 808 take turns contacting the top of the transmission rod 801, so that the push plate 807 at the bottom of the transmission rod 801 repeatedly contacts the rotating shaft 804, so that the feeding plate 601 reciprocates under the cooperation of the vibration spring 703, so that the screen 603 on the feeding plate 601 can better screen out and feed the debris.

[0036] Specifically, such as Figure 8 and Figure 9 As shown, the connecting assembly includes a mounting block 802, a return spring 806, and a fixing sleeve 805. Two mounting blocks 802 are slidably connected to the transmission rod 801. One end of each mounting block 802 is fixedly connected to one side of the upright plate 301. A fixing sleeve 805 is fixedly connected to the bottom of the transmission rod 801 near the top of the mounting block 802. A return spring 806 is mounted on the fixing sleeve 805. The bottom of the return spring 806 is fixedly connected to the mounting block 802. The return spring 806 is located outside the transmission rod 801 and is connected to the transmission rod 801. 1. The outer sliding connection, through the installation of the mounting block 802, facilitates the sliding installation of the transmission rod 801 on one side of the vertical plate 301, so as to transmit the abutment force of the protrusion 808 to the feed plate 601, thereby causing the feed plate 601 to vibrate. Through the installation of the fixing sleeve 805, it is convenient to install the return spring 806. With the cooperation of the return spring 806, it is convenient to abut and reset the transmission rod 801. After the transmission rod 801 is abutted by the protrusion 808, it can be reset in time with the cooperation of the return spring 806, so as to realize the reciprocating motion.

[0037] Specifically, such as Figure 8 , Figure 9 and Figure 10As shown, a guide wheel 803 is rotatably connected to the top of the transmission rod 801. The guide wheel 803 abuts against the outer side of the protrusion 808. The push plate 807 has an arc-shaped structure, and the arc diameter of the push plate 807 is larger than the diameter of the rotating shaft 804. The rotating shaft 804 is rotatably connected to the outer side of the feed plate 601. The installation of the guide wheel 803 makes it easier for the protrusion 808 to abut against the transmission rod 801 without causing wear, and the transmission is smooth. The arc-shaped structure design of the push plate 807 increases the contact area with the rotating shaft 804. Furthermore, the rotatable connection of the push plate 807 to the rotating shaft 804 makes the contact between the push plate 807 and the rotating shaft 804 smoother and reduces wear.

[0038] In use, this invention first facilitates the installation of the drive motor 302 and connecting shaft 303 by installing the upright plate 301. Driven by an external controller, the drive motor 302 rotates the connecting shaft 303 at a constant speed, forming the spring. Once the specified length is reached, the shearing assembly 2 is used. During shearing, the cylinder 304 controls the sliding of the upright plate 301, separating the connecting shaft 303 from the spring for easy spring dropping. Finally, the cylinder 304 controls the upright plate 301 to reset, facilitating the production of the next spring. The mounting base 401, in conjunction with the movable groove 403, allows the shearing assembly 2 to slide on the mounting base 401, adjusting the position of the shearing assembly 2 and the connecting shaft 303 to accommodate different sizes of springs. The spring shearing mechanism facilitates the production of springs of different models. Through the cooperation of the drive components, the position of the shearing component 2 can be precisely adjusted. The screw 404, driven by the thread, can precisely move the shearing component 2. The servo motor 402, under the control of an external controller, drives the screw 404, thereby controlling the position of the shearing component 2. The support block 503 facilitates the installation of the first guide plate 501 and the second guide plate 502. The 45-degree angle between the first guide plate 501, the second guide plate 502, and the top of the machine body 1 ensures smooth unloading of fallen springs. The connecting groove 504 facilitates the connection between the first guide plate 501 and the second guide plate 502. The second guide plate 502 can slide internally at one end, facilitating the adjustment of the position of the subsequent shearing assembly 2 to produce springs of different models. The installation of the feeding plate 601 facilitates the receiving of springs guided by the first guide plate 501 and the second guide plate 502. The screen 603 installed on the feeding plate 601 facilitates the removal of debris falling from the springs, ensuring clean spring discharge and reducing wear. The "U"-shaped structure design prevents the springs from rolling outwards. The installation of the feeding hopper 602 facilitates the discharge and recycling of debris screened by the screen 603. The installation of the protruding strip 604 increases the deceleration and buffering effect, slowing the springs' rolling on the screen 603 and also creating a shaking effect with the cooperation of the protruding strip 604. The installation of the fixing block 701 facilitates better debris discharge, providing stable support for the hopper 602. The installation of the slider 702, in conjunction with multiple vibration springs 703, allows for elastic sliding between the slider 702 and the top of the fixing block 701. The fixed connection between the slider 702 and the bottom of the hopper 602 further facilitates this elastic sliding, enabling subsequent vibration of the screen 603 on the discharge plate 601 and increasing the screening effect. The installation of multiple guide rods 704 guides and limits the movement between the slider 702 and the fixing block 701, ensuring smooth sliding of the slider 702 on the fixing block 701 without detachment. The connecting components facilitate the sliding installation of the transmission rod 801 on the outside of the vertical plate 301.Furthermore, the transmission rod 801 slides elastically with the connecting assembly. Through the installation of multiple protrusions 808, when the connecting shaft 303 rotates at a constant speed, the protrusions 808 take turns abutting the top of the transmission rod 801. This causes the push plate 807 at the bottom of the transmission rod 801 to repeatedly abut against the rotating shaft 804, resulting in the feeding plate 601 reciprocating under the cooperation of the vibration spring 703. This allows the screen 603 on the feeding plate 601 to better screen and discharge debris. The installation of the mounting block 802 facilitates the sliding installation of the transmission rod 801 on one side of the vertical plate 301, transmitting the abutting force of the protrusions 808 to the feeding plate 601, thus causing the feeding plate 601 to vibrate. The installation of the fixed sleeve 805 facilitates the installation of the return spring 806. The return spring 806, in conjunction with the movement, facilitates the reciprocating motion of the transmission rod 801. After being abutted by the protrusion 808, the transmission rod 801 can promptly return to its original position with the assistance of the return spring 806, achieving reciprocating motion. The installation of the guide wheel 803 reduces wear when the protrusion 808 abuts against the transmission rod 801, ensuring smooth transmission. The arc-shaped structure design of the push plate 807 increases the contact area with the rotating shaft 804, and the rotational connection with the rotating shaft 804 facilitates smoother contact between the push plate 807 and the rotating shaft 804, reducing wear.
