Description

Technical Field

[0001] This application relates to the field of spring processing equipment, and in particular to a spring compression processing equipment. Background Technology

[0002] Spring compression treatment involves pressing the spring until the stress in the material layer exceeds the yield point, causing negative residual stress on the surface and positive residual stress in the core. This improves the spring's load-bearing capacity and stabilizes the spring.

[0003] In related technologies, a compression spring high-pressure processing device includes a frame, a fixed bracket fixed on the frame, and a high-pressure hydraulic cylinder fixed on the fixed bracket, with the piston rod of the high-pressure hydraulic cylinder vertically downward. In practical applications, the compression spring is placed on the frame, and then the piston rod of the high-pressure hydraulic cylinder presses the compression spring to perform high-pressure processing.

[0004] Regarding the aforementioned technologies, the forced compression process needs to be sustained for a certain period of time. That is, the state of the forced compression cylinder pressing the spring needs to be maintained for a corresponding duration so that the stress of the spring itself exceeds the yield point before the forced compression process of the next spring is carried out. The efficiency is relatively low and there are areas for improvement. Summary of the Invention

[0005] In order to improve the relatively low efficiency of compression spring processing equipment in related technologies, this application provides a spring processing equipment.

[0006] This application provides a spring compression processing equipment, which adopts the following technical solution:

[0007] A spring compression processing device includes a frame and a mounting frame mounted on the frame. A first chain plate conveying mechanism is horizontally arranged on the frame. The second chain plate conveying mechanism includes a first chain plate belt. The first chain plate belt includes a plurality of first chain plates. Each first chain plate is fixed with a fixing block. Each fixing block has a mounting hole for placing the spring.

[0008] The mounting frame is provided with a second chain plate conveying mechanism, which is located above the first chain plate conveying mechanism. The second chain plate conveying mechanism is arranged along the conveying direction of the first chain plate conveying mechanism, and the first chain plate conveying mechanism and the second chain plate conveying mechanism move at the same speed but in opposite directions.

[0009] The second chain conveyor mechanism includes a second chain belt, which includes multiple second chain plates. A pressure bar is vertically arranged on the second chain plate, and the pressure bar is slidably arranged on the second chain plate along its axis. The second chain plate is also provided with a driving component for driving the pressure bar to move inward on the second chain plate, and both the pressure bar and the driving component correspond one-to-one with the second chain plate.

[0010] The mounting frame is also fixed with a guide frame, which is located between the upper and lower parts of the second chain plate belt. The lower side of the guide frame is provided with a guide slope for contacting the pressure bar and gradually pressing down the pressure bar, which is located near the upstream side of the first chain plate conveying mechanism in the conveying direction. The guide slope is inclined downward from the upstream side of the first chain plate conveying mechanism in the conveying direction to the downstream side of the first chain plate conveying mechanism. The lower side of the guide frame is provided with a holding surface away from the upstream side of the first chain plate conveying mechanism in the conveying direction. The holding surface is horizontal and the sides of the holding surface and the guide slope are connected close to each other.

[0011] By adopting the above technical solution, in practical application, the first and second chain plate conveying mechanisms move at the same speed but in opposite directions. Workers can sequentially place springs into the mounting holes of the fixed blocks, and the first chain plate conveying mechanism will feed the springs. Simultaneously, the second chain plate conveying mechanism will drive the pressure rod to move along with the springs, with one end of the pressure rod abutting against the guide slope on the inner side of the second chain plate. As the second chain plate conveying mechanism moves, the pressure rod will be pressed down, gradually compressing the springs. When the pressure rod abuts against the holding surface, it will maintain its downward pressure on the springs until it disengages from the holding surface. This method helps improve the efficiency of high-pressure processing of springs.

[0012] Preferably, a first flat plate is provided on the lower side of the upper portion of the first chain belt. The first flat plate is fixed to the frame and is arranged along the conveying direction of the first chain conveyor mechanism. The first flat plate abuts against the lower side of the upper portion of the first chain belt.

[0013] The lower side of the second chain belt is provided with two second flat plates on both the upper and lower sides. The two second flat plates are fixed to the mounting frame and are arranged along the conveying direction of the second chain conveyor mechanism. The two second flat plates abut against the upper and lower sides of the lower side of the second chain belt respectively.

[0014] By adopting the above technical solution, the upper part of the first chain belt is supported by the first flat plate, and the lower part of the second chain belt is clamped by two second flat plates, thereby reducing the fluctuation of the first and second chain belts when the pressure rod presses down on the spring, and helping to ensure the normal operation of the spring pressure treatment.

[0015] Preferably, a first limiting plate is fixed to one end of the pressure rod inside the second chain plate, the driving component is a return spring, the return spring is sleeved on the pressure rod, and the two ends of the return spring abut against the first limiting plate and the second chain plate respectively.

[0016] By adopting the above technical solution, when the pressure rod disengages from the guide slope and the holding surface, the return spring will push the first limiting plate and the pressure rod to move inward toward the inner side of the second chain plate, thereby helping to ensure the normal operation of the pressure rod for subsequent spring pressure processing.

[0017] Preferably, a second limiting plate is fixedly provided on the outer part of the pressure bar on the second chain plate.

[0018] By adopting the above technical solution, the pressure bar is limited by the second limiting plate, reducing the occurrence of the pressure bar detaching from the second chain plate.

[0019] Preferably, a roller is rotatably provided at one end of the pressure bar on the inner side of the second chain plate.

[0020] By adopting the above technical solution, the pressure bar contacts the guide ramp and the holding surface through rollers, which helps to improve the smoothness of the pressure bar's movement relative to the guide ramp and the holding surface.

[0021] Preferably, the mounting bracket is lifted and lowered on the frame, and the frame is also provided with a drive component for driving the mounting bracket to lift and lower.

[0022] By adopting the above technical solution, the mounting frame is lifted and lowered by the drive component, and the distance between the first chain plate conveying mechanism and the second chain plate conveying mechanism is adjusted, thereby improving the applicability of the spring pressure processing equipment to spring pressure operations of various lengths.

[0023] Preferably, the guide frame is lifted and lowered on the mounting frame, and the mounting frame is also provided with a power component for driving the guide frame to lift and lower.

[0024] By adopting the above technical solution, the guide frame is raised and lowered by the power component, thereby adjusting the pressure of the guide frame on the pressure rod, further improving the applicability of the spring pressing processing equipment to spring pressing operations of various lengths.

[0025] Preferably, a vibratory feeder is provided on the upstream side of the first chain plate conveying mechanism on the frame, and a feeding channel is provided on the frame. One end of the feeding channel is connected to the discharge port of the vibratory feeder, and the other end of the feeding channel is bent vertically downward and guides the spring into the mounting hole.

[0026] By adopting the above technical solution, the spring is supplied to the mounting hole by the cooperation of the vibratory plate and the feeding channel, which helps to improve the convenience of supplying springs to the mounting hole.

[0027] Preferably, a first electromagnet is provided on the lower side of the feeding channel to magnetically attract the spring and prevent the spring from falling.

[0028] By adopting the above technical solution, when the mounting hole is located below the feeding channel, the first electromagnet closes, and the spring falls out of the feeding channel; then, the first electromagnet starts, magnetically attracts the spring, and prevents the spring from falling further until the next mounting hole reaches below the feeding channel, at which point the first electromagnet closes again, thereby realizing the sequential supply of springs to the mounting holes.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The spring is fed by the first chain plate conveying mechanism, and the pressure rod is driven by the second chain plate conveying mechanism. The pressure rod and the guide frame work together to press down the spring, thereby realizing continuous high pressure operation on the spring and helping to improve the efficiency of high pressure operation on the spring.

[0031] 2. The lifting and lowering of the mounting frame is driven by a drive component, and the lifting and lowering of the guide frame is driven by a power component, thereby improving the applicability of the spring pressing processing equipment to spring pressing operations of various lengths.

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] This application discloses a spring compression processing device.

[0039] Reference Figure 1 and Figure 2 The spring compression processing equipment includes a frame 1 and a first chain conveyor mechanism 2 fixedly mounted on the frame 1. The first chain conveyor mechanism 2 is horizontal, and a fixing block 3 is fixed on the first chain conveyor mechanism 2. The fixing block 3 has a mounting hole 31. A mounting frame 4 is provided on one side of the frame 1 in the width direction of the first chain conveyor mechanism 2. A second chain conveyor mechanism 5 is fixedly mounted on the mounting frame 4. The second chain conveyor mechanism 5 is parallel to the first chain conveyor mechanism 2 and located directly above the first chain conveyor mechanism 2. The second chain conveyor mechanism 5 and the first chain conveyor mechanism 2 move at the same speed but in opposite directions. The second chain conveyor mechanism 5 includes a second chain belt 51, which includes multiple second chain plates 511. Each second chain plate 511 has a pressure rod 6 vertically sliding on it. The mounting frame 4 is also provided with a guide frame 7 for guiding the pressure rod 6 to compress the spring. Furthermore, a feeding assembly 8 is provided upstream of the first chain conveyor mechanism 2 in the conveying direction. In practical application, the feeding component 8 supplies the spring to the mounting hole 31, and the first chain plate conveying mechanism 2 drives the fixed block 3 and the spring to feed; then, the second chain plate conveying mechanism 5 drives the pressure rod 6 to move, and the guide frame 7 guides the pressure rod 6 to press down the spring, so as to perform strong pressure treatment on the spring.

[0040] Specifically, see Figure 2 Both the first chain conveyor mechanism 2 and the second chain conveyor mechanism 5 are chain conveyors. The first chain conveyor mechanism 2 includes a first chain belt 21, which includes multiple first chain plates 211. Fixing blocks 3 are fixed to the first chain plates 211, and each fixing block 3 corresponds to one of the first chain plates 211. A first flat plate 22 is provided inside the first chain belt 21. The first flat plate 22 is fixed to the frame of the first chain conveyor mechanism 2 and relative to the frame 1. The first flat plate 22 is arranged along the conveying direction of the first chain conveyor mechanism 2, and the upper side of the first flat plate 22 abuts against the lower side of the upper part of the first chain belt 21. Both ends of the first flat plate 22 are chamfered to reduce the occurrence of contact between the ends of the first flat plate 22 and the first chain plates 211. In practical applications, springs can be placed one by one into the corresponding mounting holes 31, and the first chain plate conveying mechanism 2 feeds the springs one by one. When the pressure rod 6 presses down on the springs, the first flat plate 22 supports the lower side of the first chain plate 211 to ensure the stability of the springs.

[0041] See Figure 1 and Figure 2The frame 1 is equipped with a driving component on one side of the mounting frame 4. The driving component is a first slide table 11, the frame of which is fixed to the frame 1. The slide plate of the first slide table 11 moves vertically, and the mounting frame 4 is fixed to the slide plate of the first slide table 11. In this embodiment, the first slide table 11 is an electric slide table. In practical applications, the first slide table 11 can drive the mounting frame 4 and the second chain plate conveying mechanism 5 to move upward, and the distance between the second chain plate conveying mechanism 5 and the first chain plate conveying mechanism 2 can be adjusted to accommodate high-pressure operations with springs of different lengths.

[0042] See Figure 3 and Figure 4 Each pressure rod 6 has the same structure on its corresponding second chain plate 511. The following description uses one pressure rod 6 as an example. The pressure rod 6 is axially perpendicular to the second chain plate 511, passes through the second chain plate 511 along its axial direction, and slides through it. A first limiting plate 61 is fixed to one end of the pressure rod 6 on the inner side of the second chain plate 511. A return spring 62 is sleeved on the side of the pressure rod 6 located on the inner side of the second chain plate 511, with both ends of the return spring 62 abutting against the second chain plate 511 and the first limiting plate 61, respectively. Furthermore, a second limiting plate 63 is fixed to the outer part of the pressure rod 6 on the second chain plate 511, and a roller 64 is rotatably mounted on one end of the pressure rod 6 on the inner side of the second chain plate 511.

[0043] The guide frame 7 is located inside the second chain conveyor belt 51 and is arranged along the conveying direction of the second chain conveyor mechanism 5. The frame of the second chain conveyor mechanism 5 has a clearance opening 52 on one side of its width. The mounting frame 4 has a power component on one side of the clearance opening 52. The power component is a second slide table 41, the frame of which is fixed to the mounting frame 4. The slide plate of the second slide table 41 moves vertically. The guide frame 7 passes through the clearance opening 52 on one side and is fixed to the slide plate of the second slide table 41. In this embodiment, the second slide table 41 is an electric slide table. Simultaneously, a guide ramp 71 is provided on the lower side of the guide frame 7 near the feeding assembly 8. The guide ramp 71 is inclined downwards from the feeding assembly 8 towards the side away from it. A holding surface 72 is provided on the lower side of the guide frame 7 away from the feeding assembly 8. The holding surface 72 is horizontal, and the sides of the holding surface 72 and the guide ramp 71 are connected close to each other.

[0044] To ensure the stability of the pressure spring under the pressure rod 6, two second flat plates 53 are abutted against the upper and lower sides of the lower portion of the second chain plate belt 51. The length direction of both second flat plates 53 is along the conveying direction of the second chain plate conveying mechanism 5. The two second flat plates 53 are fixed to the frame of the second chain plate conveying mechanism 5, and one second flat plate 53 is provided on each side of the width direction of the second chain plate conveying mechanism 5. Both ends of the two second flat plates 53 are chamfered to reduce the occurrence of contact between the ends of the second flat plates 53 and the second chain plate 511.

[0045] In practical applications, the guide frame 7 can be moved by the second slide table 41 according to the compression length of the spring, and the downward stroke of the guide frame 7 on the pressure rod 6 can be adjusted. Then, the second chain plate conveying mechanism 5 and the first chain plate conveying mechanism 2 move at the same speed but in opposite directions. The roller 64 on the pressure rod 6 will contact the guide inclined surface 71, and under the guidance of the guide inclined surface 71, the pressure rod 6 will move downward and compress the spring to be compressed. When the roller 64 on the pressure rod 6 abuts the holding surface 72, the pressure rod 6 will maintain the same pressure on the spring within the range of the holding surface 72, thereby completing the spring compression process. At the same time, the return spring 62 is in a compressed state. When the pressure rod 6 is separated from the holding surface 72, the return spring 62 will push the pressure rod 6 away from the compressed spring.

[0046] See next. Figure 1 The feeding assembly 8 includes a vibratory feeder 81 and a feeding channel 82. The feeding channel 82 is mounted on the frame 1. One end of the feeding channel 82 is connected to the discharge port of the vibratory feeder 81. The side of the feeding channel 82 away from the vibratory feeder 81 is bent downwards, and the end of the feeding channel 82 away from the vibratory feeder 81 is located directly above the end of the first chain conveyor mechanism 2 near the vibratory feeder 81, supplying springs into the mounting hole 31. Furthermore, a first electromagnet 821 is fixed to the lower end of the feeding channel 82. In practical application, the vibratory feeder 81 organizes the springs and supplies them into the feeding channel 82. When the first electromagnet 821 is started, it magnetically attracts the springs and prevents them from falling. When the mounting hole 31 is located directly below the lower end of the feeding channel 82, the first electromagnet 821 is turned off, and the springs will fall downwards into the mounting hole 31. The first electromagnet 821 is activated in time after a single spring falls into the mounting hole 31 and prevents other springs from falling downwards.

[0047] The implementation principle of the spring compression processing equipment in this application embodiment is as follows: In actual use, the vibratory plate 81 tidies up the spring and supplies it into the feeding channel 82; then, the spring is guided by the feeding channel 82 and supplied into the mounting hole 31 of the fixed block 3, and fed under the drive of the first chain plate conveying mechanism 2; at the same time, the second chain plate conveying mechanism 5 moves at the same speed and in the opposite direction to the first chain plate conveying mechanism 2, and the pressure rod 6 moves with the second chain plate conveying mechanism 5; subsequently, the roller 64 of the pressure rod 6 contacts the guide inclined surface 71, and the pressure rod 6 gradually descends and presses down on the spring under the guidance of the guide inclined surface 71, and the first limiting plate 61 compresses the reset spring 62; when the roller 64 of the pressure rod 6 contacts the holding surface 72, the pressure rod 6 will maintain the same pressure on the spring within the range of the holding surface 72; when the pressure rod 6 leaves the holding surface 72, the reset spring 62 will push the pressure rod 6 to release the spring, thus completing the compression operation on the spring.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
