Description

Technical Field

[0001] This utility model relates to the field of spring manufacturing technology, and in particular to a spring manufacturing device. Background Technology

[0002] In the process of manufacturing springs using metal flats, punching and bending operations are required to meet specific production needs. The punching operation involves punching material at predetermined positions on the metal flats to form punched holes at those positions. The bending operation involves bending the punched metal flats in a predetermined direction to form a spring.

[0003] Currently, in the spring processing, punching and bending operations are both completed at the front end of the machine, and the power required for punching and bending is provided by the machine's built-in power source. Due to the limitation of the machine's built-in power, punching can only be performed on some thinner flat materials (thicker products cannot be processed). When punching some thicker flat materials, the insufficient power of the machine's built-in power results in poor punching stability, which leads to poor dimensional stability of the spring parts during subsequent bending operations, resulting in an increased defect rate and hindering spring manufacturing.

[0017] In one embodiment, the punching assembly further includes:

[0018] A plurality of guide rods extend along the Y-direction and are fixedly connected to the side of the second base plate facing the first base plate. In the Y-direction, a guide hole is provided through the base body at a position corresponding to the guide rod, and the guide rod passes through the guide hole for slidingly mounting the second base plate onto the base body along the Y-direction.

[0019] An elastic element is connected between the second seat plate and the seat body.

[0020] In one embodiment, the spring manufacturing apparatus further includes a guide member arranged along the X direction, and in the X direction, the guide member passes through the machine base;

[0021] In the X direction, a guide groove is provided through the guide member, and the cross-sectional profile of the guide groove is matched with the cross-sectional profile of the flat material, and the guide groove constitutes the channel.

[0022] In one embodiment, in the X direction, the machine base is provided with a through mounting hole, and the guide member is installed in the mounting hole;

Furthermore, since no major adjustments or modifications are made to the internal wiring and structural layout of the machine, the cost of modification is also reduced to some extent.

[0055] In the process of manufacturing springs using metal flats, punching and bending operations are required to meet specific production needs. The punching operation involves punching material at predetermined positions on the metal flats to form punched holes at those positions. The bending operation involves bending the punched metal flats in a predetermined direction to form a spring.

[0056] Currently, in the spring processing, punching and bending operations are both completed at the front end of the machine, and the power required for punching and bending is provided by the machine's built-in power source. Due to the limitations of the built-in power, only some thinner flat materials can be punched (thicker products cannot be processed). When punching some thicker flat materials, the insufficient power of the built-in power results in poor punching stability, which in turn leads to poor dimensional stability during subsequent bending operations, resulting in a higher defect rate and hindering spring production. If the built-in power source of the machine is to be modified and upgraded, the entire machine needs to be disassembled, and significant adjustments need to be made to the internal wiring and spatial layout, resulting in high modification costs.

[0057] Based on this, refer to Figures 1-9 As shown, this application provides a spring manufacturing apparatus with intersecting X and Y directions, including a machine base 1, a punching assembly 3, and a cutting assembly 4; in this embodiment, the X direction is the extension direction of the production line, and the Y direction is the direction perpendicular to the extension of the production line; the machine base 1 has a channel through it in the X direction for passing a flat material 9, and the machine base 1 has a bending assembly 2 on one side along the X direction for bending the flat material 9 extending from the channel, thereby bending the flat material 9 into a preset shape; as Figure 2 , Figure 3 As shown, the punching assembly 3 is located on the other side of the machine base 1 along the X direction, and is used to punch out preset shapes such as holes and slots on the flat material 9. The punching assembly 3 is driven by a separate power source. The cutting assembly 4 is installed on the machine base 1 and is located on the same side as the bending assembly 2. It is used to cut the flat material 9 after punching and bending operations to obtain the required spring parts. The metal flat material 9 in this solution is generally high carbon steel, which has high strength and elastic properties.

[0058] Understandably, both the traditional punching assembly 3 and bending assembly 2 are located at the front end of the machine tool 1 and rely on the built-in power source of the machine tool 1. Due to the limited power of the built-in power source of the machine tool 1, the equipment can only punch thinner flat materials 9. When punching thicker flat materials 9, the insufficient power reduces the stability of the flat materials 9 during punching, resulting in poor dimensional stability of the spring parts during bending and forming, which is not conducive to the production of springs. If the built-in power source of the machine tool 1 is updated and adjusted, the machine tool 1 needs to be completely disassembled, and its internal wiring and spatial layout need to be significantly adjusted, resulting in a large workload, a complicated process, and a significant increase in modification costs.

[0059] In this embodiment, by adjusting the position of the punching component 3, which was originally arranged at the front end of the machine tool 1 and used the built-in power of the machine tool 1 to perform punching, and by equipping the punching component 3 with a separate power source for driving, it is possible to process flat materials 9 of different thicknesses, thereby improving the adaptability of the equipment. While achieving the ability to punch flat materials 9 of different thicknesses, the layout of the machine tool 1 is not adjusted or modified, which helps to reduce the cost of modification.

[0060] Reference Figure 2 , Figure 3 As shown, in one embodiment of this application, the punching assembly 3 and the channel are connected to form a production line. The punching assembly 3 includes a first base plate 31 and a second base plate 32. The first base plate 31 is fixedly arranged on the production line, and a through groove 311 is provided on the first base plate 31 along the X direction (e.g., ...). Figure 6 As shown), the flat material 9 passes through the second seat plate 32 via the aforementioned through groove 311; in the Y direction, the second seat plate 32 is located on one side of the production line, and the second seat plate 32 is movable along the Y direction; as Figure 6 As shown, the first base plate 31 has a punching hole 312 on the side facing the second base plate 32, which communicates with the outside and the through groove 311, as shown. Figure 7 As shown, the second base plate 32 is provided with a punching head 321 that cooperates with the punching hole 312 on the side facing the first base plate 31.

[0061] In this embodiment, when the flat metal 9 on the production line passes through the through slot 311 provided in the first seat plate 31, it drives the second seat plate 32 to move toward the first seat plate 31. With the cooperation of the punching head 321 and the punching hole 312, the flat metal 9 passing through the through slot 311 is punched, and preset shapes such as holes and slots are punched on the flat metal 9. It can be understood that the shape and outline of the punching head 321 and the shape and outline of the punching hole 312 should be matched. When the metal flat metal 9 moves in the through slot 311, the two side walls of the metal flat metal 9 along the Y direction contact the two side walls of the through slot 311 along the Y direction, respectively. This enables the punching head 321 to support the metal flat metal 9 when punching it (avoiding deformation and bending caused by the punching of the punching head 321).

[0062] In this embodiment, as Figure 6 , Figure 7 , Figure 8 As shown, this embodiment provides a specific structure and shape setting for the punching head 321 and the punching hole 312. The structural settings of the punching head 321 and the punching hole 312 in this embodiment are adjusted according to the requirements of the spring to be processed, and are not limited to a specific structure or shape.

[0063] It is understandable that, in the Y direction, the punching hole 312 should be completely through the first base plate 31 (the base 6 also has a hole through the first base plate 31 for mounting the base plate 31). This allows the punching head 321 to move within the punching hole 312 and punch the metal flat 9 when the second base plate 32 drives the punching head 321 to punch the metal flat 9. When the punching head 321 completely penetrates the metal flat 9, it can enter the punching hole 312 located on the side of the through groove 311 opposite to the second base plate 32, and the waste material punched off the metal flat 9 can be discharged outward from the other end of the punching hole 312.

[0064] Reference Figure 2 , Figure 3 , Figure 5 As shown, in one embodiment of this application, the punching assembly 3 further includes a telescopic member 5. The telescopic member 5 is disposed on the side of the second seat plate 32 away from the first seat plate 31, and the telescopic member 5 has a telescopic portion 51 facing the second seat plate 32. The telescopic portion 51 is used to drive the second seat plate 32 to move in the Y direction, thereby realizing the punching of the metal flat material 9 passing through the through groove 311.

[0065] It is understood that the telescopic component 5 can be a hydraulic rod, an electric rod, or other components capable of linear motion. When the telescopic component 5 is a hydraulic rod, it is equipped with a separate hydraulic press to provide driving pressure. The telescopic part 51 is the telescopic part of the hydraulic rod or the electric rod. It is understood that the telescopic component 5 includes a telescopic part and a fixed part. For example, a hydraulic rod includes a hydraulic cylinder (fixed part) and a telescopic rod (constituting the telescopic part 51).

[0066] In this embodiment, by adjusting the position of the punching component 3, and since the punching component 3 has a separate power source, punching operations can be performed on metal flats 9 of different thicknesses. Compared with directly updating or adjusting the power source built into the machine tool 1 (which requires completely disassembling the machine tool 1 and making significant adjustments to its internal wiring and spatial layout), the operation is simpler, more convenient, and reduces the modification cost.

[0067] Reference Figure 1 , Figure 5As shown, in one embodiment of this application, the punching assembly 3 further includes a base 6, and the telescopic member 5 and the first base plate 31 are fixedly installed on the base 6; wherein the second base plate 32 is movably connected to the base 6 along the Y direction, and the second base plate 32 and the base 6 are elastically connected; the telescopic part 51 has an initial position that is separated from the second base plate 32 and an abutting position that abuts against the second base plate 32 (the position where the telescopic part 51 abuts against the second base plate 32 is the side wall of the second base plate 32 away from the first base plate 31). When the telescopic part 51 is in the initial position, the punching head 321 is in the standby position; when the telescopic part 51 is in the abutting position, the second base plate 32 can be driven to move the punching head 321 in the punching hole 312 and perform punching operation on the metal flat material 9 passing through the through groove 311. During this process, the elastic member 34 connected between the base 6 and the second base plate 32 is compressed and stores energy.

[0068] In this embodiment, by controlling the extension amount of the telescopic part 51 of the telescopic member 5, the stroke of the punching head 321 along the Y direction is ensured to punch the flat material 9 and form a preset hole or groove shape on the flat material 9. It can be understood that when the telescopic part 51 reaches the predetermined extension amount, the telescopic member 5 controls the telescopic part 51 to retract, that is, to move in the opposite direction to the initial position. Then, the second seat plate 32 and the punching head 321 move synchronously in the opposite direction under the action of the elastic member 34, thereby completing one punching process of the metal flat material 9. It can be understood that when the punching of the metal flat material 9 begins, the metal flat material 9 on the production line should be stationary. Only after one punching process is completed and the telescopic part 51 and the punching head 321 (second seat plate 32) have both been reset can the metal flat material 9 continue to move for subsequent bending processing.

[0069] Reference Figure 5 , Figure 6 , Figure 7 As shown, in one embodiment of this application, the punching assembly 3 further includes guide rods 33 and elastic elements 34; wherein, there are multiple guide rods 33, all of which extend along the Y direction, and each guide rod 33 is fixedly connected to the side wall of the second base plate 32 facing the first base plate 31; as shown Figure 5 As shown, a guide hole 61 corresponding to the position of the guide rod 33 is provided through the seat body 6 along the Y direction. The guide rod 33 is slidably assembled in the corresponding guide hole 61, thereby realizing the sliding installation of the second seat plate 32 on the seat body 6; it can be understood that the elastic element 34 can be a spring, such as Figure 6 , Figure 7As shown, the elastic element 34 is sleeved on the outer periphery of the guide rod 33, and its two ends along the Y direction are respectively connected to the second seat plate 32 and the seat body 6. When the telescopic part 51 abuts against the side wall of the second seat plate 32 away from the first seat plate 31 and drives the second seat plate 32 to move toward the first seat plate 31, the elastic element 34 will be squeezed and compressed as the second seat plate 32 moves. When one punching process is completed and the telescopic part 51 is reset, the elastic element 34 will drive the second seat plate 32 to move away from the first seat plate 31 and reset.

[0070] Reference Figure 1 , Figure 9 As shown, in one embodiment of this application, the spring manufacturing apparatus further includes a guide 7, which is arranged along the X-direction and passes through the machine base 1 in the X-direction. Figure 9 As shown, in the X direction, a guide groove 71 (which constitutes the channel mentioned above) is provided through the guide member 7, and the cross-sectional profile of the guide groove 71 is matched with the cross-sectional profile of the metal flat member 9, thereby guiding the metal flat member 9 to move on the production line and constraining and limiting the movement trajectory of the metal flat member 9.

[0071] Reference Figure 9 As shown, in one embodiment of this application, in the X direction, the machine base 1 is provided with a through mounting hole 11, the guide member 7 is installed in the mounting hole 11, and the guide member 7 is detachably connected to the mounting hole 11; for example, the guide member 7 can be a cylindrical rod structure, and the mounting hole 11 is also circular. A pin can be provided on the machine base 1 near the guide member 7, and an insertion hole extending radially along the periphery of the guide member 7 can be provided. The pin is inserted into the insertion hole to achieve the positioning of the guide member 7 relative to the machine base 1.

[0072] In this embodiment, the guide 7 is detachably connected to the mounting hole 11. Depending on the specifications of the spring to be prepared, the guide 7 can be replaced with a matching one (the size of the guide groove 71 in the guide 7 is adjusted synchronously) to cooperate with metal flats 9 of different specifications and to constrain and limit the metal flats 9 when they move on the production line.

[0073] Reference Figure 1As shown in one embodiment of this application, the bending assembly 2 includes multiple bending members 21, which are arranged at intervals along the surrounding channel. Each bending member 21 is connected to the machine base 1 and moves radially along the channel. The end of the bending member 21 near the guide member 7 has a bending head for bending the metal flat material 9 extending from the guide groove 71. According to the bending requirements, the corresponding bending member 21 is controlled to move radially toward the metal flat material 9 along the channel. The bending head acts on the metal flat material 9 to bend it to a preset angle. During the bending process, after the metal flat material 9 moves forward a preset distance, a bending member 21 acts on the metal flat material 9 at a preset position and bends the metal flat material 9 to a preset angle (during this process, the metal flat material 9 remains stationary). That is, the bending operation of the metal flat material 9 is performed multiple times at intervals.

[0074] It is understood that the bending assembly 2 also includes a first drive unit 22 for driving the bent piece 21 to move radially along the channel. The first drive unit 22 includes a power source (not shown in the figure) built into the machine base 1, a connecting rod mounted on the side wall of the machine base 1, and a cam directly driven by the power source. The connecting rod is rotatably mounted on the side wall of the machine base 1 (a torsion spring is provided at the pivot of the connecting rod for resetting the connecting rod), and one end of the connecting rod cooperates with the cam, and the other end cooperates with the bent piece 21 (for driving the bent piece 21 to move); Figure 9 As shown, a slider is slidably mounted on the end of the connecting rod away from the cam, and the slider is rotatably mounted on the end of the bending piece 21 away from the channel. Thus, when the power source built into the machine tool 1 drives the cam to rotate, the cam will force the connecting rod to rotate. Thus, through the cooperation of the slider, the bending piece 21, and the connecting rod, the bending piece 21 is driven to move along the channel (when the cam protrusion no longer abuts against the connecting rod, the connecting rod is reset under the action of the torsion spring, thereby driving the bending piece 21 to move away from the channel), and the metal flat material 9 is bent at the preset position. The structure of the first driving part 22 used to drive the bending piece 21 is all prior art, and the improvement point of this solution is not in this aspect. Therefore, its working process will not be described in detail here.

[0075] Reference Figure 1 As shown, in one embodiment of this application, the cutting assembly 4 includes a cutting part 41, which is arranged to move radially along the channel. The cutting part 41 has a cutting head on the side facing the channel for cutting the metal flat material 9. The cutting head is used to cut the bent flat material 9 at a preset position, thereby preparing the desired spring product. The cutting assembly 4 also includes a second driving part 42 for driving the cutting part 41 to move. The structure of the second driving part 42 can be the same as that of the first driving part 22, or it can be other structures, as long as it can drive the cutting part 41 to move back and forth radially along the channel according to production needs.

[0076] Reference Figure 2 , Figure 3 , Figure 4 As shown, in one embodiment of this application, the spring manufacturing apparatus further includes a feeding assembly 8, which is disposed between the punching assembly 3 and the machine base 1, and is used to drive the metal flat material 9 to move on the production line; the feeding assembly 8 includes a first roller 81, a second roller 82 and a driving component; wherein, the first roller 81 and the second roller 82 are rotatably mounted on the base 6 at appropriate positions, and in the Y direction, the first roller 81 and the second roller 82 are arranged at intervals to form a feeding channel 83 between the first roller 81 and the second roller 82 (e.g., Figure 4 (as shown); the flat material 9 is inserted into the feeding channel 83. In the Y direction, the two ends of the flat material 9 respectively abut against the first roller 81 and the second roller 82 (when the first roller 81 and the second roller 82 rotate, the friction between the surface of the first roller 81 and the second roller 82 and the metal flat material 9 will drive the metal flat material 9 to move on the production line); the driving component (not shown in the figure) is connected to the first roller 81 and / or the second roller 82 and is used to drive the first roller 81 and / or the second roller 82 to rotate.

[0077] It is understood that the driving component can be a motor, with the motor's output shaft connected to the first roller 81 and / or the second roller 82. For example, two motors can be provided to drive the first roller 81 and the second roller 82 to rotate respectively. It should be noted that the rotation directions of the first roller 81 and the second roller 82 should be opposite (at this time, the frictional forces acting on the metal flat material 9 by the first roller 81 and the second roller 82 are in the same direction), thereby driving the metal flat material 9 passing through the feed channel 83 to move on the production line. Alternatively, a single motor can be provided, and a transmission mechanism can be provided to connect the motor to the first roller 81 and the second roller 82 respectively, to drive the first roller 81 and the second roller 82 to rotate in opposite directions, thereby driving the metal flat material 9 passing through the feed channel 83 to move on the production line.

[0078] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
