Abstract
Description
Technical Field
[0001] This application relates to the field of spring manufacturing technology, and more specifically, to a spring bending and forming apparatus. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. It is made of elastic material and deforms under the action of external force. After the external force is removed, it returns to its original shape. It is generally made of spring steel. In the spring production process, a spring processing and bending device is required for auxiliary cooperation.
[0003] In response, Chinese patent application number CN202321078969.1 discloses a spring processing and bending device. This solution mainly involves placing a winding roller of a corresponding size outside the cross-section of a fixed shaft and a clamping plate, aligning the ends of the fixed shaft and clamping plate with a fixed base, inserting them into the insertion holes of the fixed base, and installing the other end of the fixed shaft into the clamping hole through a clamping groove. Then, the motor is turned on, and the central shaft drives the first gear to rotate. With the cooperation of the first gear, the winding roller is rotated, realizing the rapid disassembly and assembly of some components of the spring processing and bending device, and improving the work efficiency of maintenance and repair operations.
[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the inventors of this utility model discovered that the above-mentioned technology has at least the following technical problems:
[0005] 1. After the spring is wound, it is still at a high temperature, and both ends of the roller are blocked, making it difficult to remove the spring.
[0006] 2. The front end of the spring needs to be fixed to the outer circle of the roller using a clamping device. However, the above solution does not disclose the relevant structure, and combined with the existing technology, it is difficult to achieve both convenient replacement and bending of the roller at the same time. Utility Model Content
[0007] To overcome the above deficiencies, this application provides a spring production bending and forming apparatus, which aims to improve the problems mentioned in the background art.
[0008] This application provides a spring production bending and forming apparatus, including a frame. A rotating mechanism is provided at one end of the frame, a holding mechanism is provided on the rotating mechanism, a translation mechanism is provided on the frame, a mandrel mechanism and a guide mechanism are provided on the translation mechanism, the mandrel mechanism includes a slide block, the slide block is disposed on the translation mechanism, a core column is rotatably connected to the slide block, the core column abuts against the holding mechanism, a core sleeve is sleeved on the core column, and a pin locking structure is provided on the core column to pin-connect with the core sleeve.
[0009] In one specific implementation, the rotating mechanism includes a rotating shaft and a rotary motor, the rotating shaft being rotatably connected to the frame, and the rotary motor being power-connected to the rotating shaft.
[0010] In the above process, the rotary motor drives the shaft to rotate through the linkage of the worm gear and worm, thereby realizing the winding action.
[0011] In one specific implementation, the pressing mechanism includes a stop block, which is fixedly connected to the rotating shaft. A transition block is slidably connected to the stop block, and a pressure head is slidably connected to the transition block. A set screw is screwed onto the transition block and abuts against the pressure head. A rib pin is fixedly connected to the stop block and pinned to the core post.
[0012] In the above process, when the core column is pressed against the abutment block, the prism pin is inserted into the core column to achieve shaft connection. In addition, the extension amount of the pressure head can be adjusted according to springs of different diameters to avoid interfering with the guiding mechanism. After the pressure head is adjusted, it is tightened and fixed by the set screw.
[0013] In one specific implementation, the pressing mechanism further includes a clamping motor, which is installed inside the rotating shaft. A gear is fixedly connected to the output end of the clamping motor, and a rack is fixedly connected to the adapter block to mesh with the gear.
[0014] In the above implementation process, the clamping motor drives the gear to rotate, thereby driving the adapter block to move radially. The clamping motor has a reduction mechanism with a large reduction ratio, thereby increasing the clamping force and clamping force self-locking. The power supply and control line of the clamping motor is led out from the outer end of the rotating shaft through a conductive slip ring. In another embodiment, a hydraulic cylinder is provided inside the abutment block to drive the adapter block to move, and the hydraulic oil pipe of the hydraulic cylinder is connected to the external oil supply mechanism through a rotary joint.
[0015] In one specific implementation, the guiding mechanism includes a slide and an electric cylinder, the slide being mounted on the translation mechanism, and a guide wheel being provided on the output end of the electric cylinder.
[0016] In the above implementation process, a wheel frame is fixedly connected to the telescopic end of the electric cylinder, and a guide rod is fixedly connected to the wheel frame. The guide rod is slidably connected to the slide, thereby stabilizing the posture of the wheel frame. The guide wheel is inserted into the shaft on the wheel frame, and the outer end of the shaft is restricted to the wheel frame by a snap ring, making the guide wheel easy to replace.
[0017] In one specific implementation, the locking structure includes a spring piece located inside the core post, and a pin fixedly connected to the spring piece, the pin movably passing through the side wall of the core post and engaging with the core sleeve.
[0018] In one specific implementation, the pin lock structure further includes a push post, which is slidably connected to the core post. A compression spring is provided between the push post and the core post, and an abutment ring is provided on the push post to slidably abut against the spring piece.
[0019] In the above process, the compression spring pushes the push post to the initial position. At this time, the abutment ring on the push post abuts against the back of the pin and the spring piece, pushing the pin out to connect with the core sleeve. When the core sleeve needs to be replaced, press the push post, the abutment ring moves away from the position of the pin, the spring piece begins to reset and pulls the pin away from the core sleeve, so that the core sleeve can be pulled out for replacement.

The slide rail is fixed on the frame, and the slide frame and the slide base are slidably connected to the slide rail. The lead screw is rotatably connected to the frame. There are two lead screws, and the two lead screws are threadedly connected to the slide frame and the slide base respectively. Each lead screw is powered by a translation motor.
[0021] In the above implementation process, the two translation motors drive the corresponding lead screws to rotate, which in turn drive the guide mechanism and the mandrel mechanism to translate.
[0022] Compared with the prior art, the beneficial effects of this application are: the core sleeve is pinned to the core post by the pin-lock structure, which realizes the convenient replacement of the core sleeve; after replacement, the translation mechanism presses the core rod mechanism against the holding mechanism, and rotates under the drive of the rotation mechanism to realize the winding action; after the winding is completed, the guide mechanism presses against the spring, and the translation mechanism moves the core rod mechanism away, so that the core rod can fall automatically.

Detailed Implementation
[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0030] Please see Figures 1-4 This application provides a spring production bending and forming device, including a frame 10, a rotating mechanism 20 at one end of the frame 10, a holding mechanism 30 on the rotating mechanism 20, a translation mechanism 40 on the frame 10, a mandrel mechanism 50 and a guide mechanism 60 on the translation mechanism 40, the mandrel mechanism 50 including a slide 51, the slide 51 being disposed on the translation mechanism 40, a core column 52 being rotatably connected to the slide 51, the core column 52 abutting against the holding mechanism 30, a core sleeve 53 being sleeved on the core column 52, and a pin locking structure being provided on the core column 52 to be pin-connected to the core sleeve 53. The core sleeve 53 is pinned to the core post 52 using a pin-locking structure, which enables convenient replacement of the core sleeve 53. After replacement, the translation mechanism 40 presses the core rod mechanism 50 against the holding mechanism 30 and rotates under the drive of the rotation mechanism 20 to achieve the winding action. After winding is completed, the guide mechanism 60 presses against the spring, and the translation mechanism 40 moves the core rod mechanism 50 away, so that the core rod can fall automatically.
[0031] Please see Figures 1-4 The rotating mechanism 20 includes a rotating shaft 21 and a rotary motor 22. The rotating shaft 21 is rotatably connected to the frame 10, and the rotary motor 22 is poweredly connected to the rotating shaft 21. The rotary motor 22 drives the rotating shaft 21 to rotate through the linkage of a worm gear and a worm, thereby realizing the winding action.
[0032] Please see Figures 1-4The pressing mechanism 30 includes a stop block 31, which is fixedly connected to the rotating shaft 21. A transition block 32 is slidably connected to the stop block 31, and a pressing head 33 is slidably connected to the transition block 32. A set screw 34 is screwed onto the transition block 32 and abuts against the pressing head 33. A prism pin 35 is fixedly connected to the stop block 31 and pinned to the core column 52. When the core column 52 abuts against the stop block 31, the prism pin 35 is inserted into the core column 52 to achieve shaft connection. In addition, the extension amount of the pressing head 33 can be adjusted according to springs of different diameters to avoid interfering with the guiding mechanism 60. After the pressing head 33 is adjusted, it is tightened and fixed by the set screw 34.
[0033] Please see Figures 1-4 The holding mechanism 30 also includes a clamping motor 36, which is installed inside the rotating shaft 21. A gear 37 is fixedly connected to the output end of the clamping motor 36, and a rack 38 is fixedly connected to the adapter block 32, meshing with the gear 37. The clamping motor 36 drives the gear 37 to rotate, thereby driving the adapter block 32 to move radially. The clamping motor 36 has a reduction mechanism with a large reduction ratio, thereby increasing the holding force and the holding force self-locking. The power supply and control lines of the clamping motor 36 are led out from the outer end of the rotating shaft 21 through a conductive slip ring. In another embodiment, a hydraulic cylinder is provided inside the abutment block 31 to drive the adapter block 32 to move, and the hydraulic oil pipe of the hydraulic cylinder is connected to an external oil supply mechanism through a rotary joint.
[0034] Please see Figures 1-4 The guiding mechanism 60 includes a slide 61 and an electric cylinder 62. The slide 61 is mounted on the translation mechanism 40, and a guide wheel 63 is provided on the output end of the electric cylinder 62. A wheel frame is fixedly connected to the telescopic end of the electric cylinder 62, and a guide rod is fixedly connected to the wheel frame. The guide rod is slidably connected to the slide 61 to stabilize the wheel frame posture. The guide wheel 63 is inserted into the shaft on the wheel frame, and the outer end of the shaft is restricted to the wheel frame by a retaining spring, making the guide wheel 63 easy to replace.
[0035] Please see Figures 1-4 The locking structure includes a spring plate 54 located inside the core post 52. A pin 55 is fixedly connected to the spring plate 54, and the pin 55 movably passes through the side wall of the core post 52 and is pinned to the core sleeve 53. The locking structure also includes a push post 56, which is slidably connected to the core post 52. A compression spring 58 is provided between the push post 56 and the core post 52. A retaining ring 57 is provided on the push post 56 and slides against the spring plate 54. The compression spring 58 pushes the push post 56 to the initial position. At this time, the retaining ring 57 on the push post 56 abuts against the back of the pin 55 and the spring plate 54, pushing the pin 55 out to pin the core sleeve 53. When the core sleeve 53 needs to be replaced, the push post 56 is pressed, the retaining ring 57 moves away from the position of the pin 55, the spring plate 54 begins to reset, pulling the pin 55 away from the core sleeve 53, so that the core sleeve 53 can be pulled out for replacement, which is convenient for replacing core sleeves 53 of different diameters.
[0036] Please see Figures 1-4The translation mechanism 40 includes a slide rail 41 and a lead screw 42. The slide rail 41 is fixed to the frame 10. The slide carriage 61 and the slide base 51 are slidably connected to the slide rail 41. The lead screw 42 is rotatably connected to the frame 10. There are two lead screws 42, which are threadedly connected to the slide carriage 61 and the slide base 51, respectively. Each lead screw 42 is powered by a translation motor 43. The two translation motors 43 drive the corresponding lead screw 42 to rotate, thereby driving the guide mechanism 60 and the mandrel mechanism 50 to translate.
[0037] The working principle of the spring production bending and forming device is as follows: Pressing the push post 56 places the core sleeve 53 of a specified diameter onto the core post 52. Then, releasing the push post 56, the push post 56 returns to its original position under the elastic force of the compression spring 58, moving the abutment ring 57 to the position of the pin 55, pushing the pin 55 out to engage with the core sleeve 53, thus enabling quick replacement of the core sleeve 53. The translation motor 43 drives the slide block 51 to push the core post 52 onto the abutment block 31, and the rib pin 35 on the abutment block 31 is inserted into the core post 52 to achieve shaft connection. According to the wire diameter, the extension of the pressure head 33 is adjusted to avoid interfering with the guide mechanism 60. After the pressure head 33 is adjusted, it is tightened and fixed using the set screw 34. The front end of the wire is pressed against the protrusion on the pressure head 33, and then the clamping motor 36 drives the gear 37 to rotate, thereby driving the adapter block 32 to move radially, pressing the wire against the core. The outer circle of sleeve 53 is rotated; the rotary motor 22 drives the abutment block 31 and the core sleeve 53 to rotate, and the wire is wound around the core sleeve 53 under the guidance of the guide wheel 63; finally, the guide wheel 63 lightly abuts against the spring, and the translation motor 43 pulls the core sleeve 53 back, and the spring falls off the core sleeve 53. It should be noted that the frame 10 can be fixed horizontally on the vertical mounting plate, so that a receiving plate can be set below. In summary, the core sleeve 53 is pinned to the core column 52 by the pin locking structure, which realizes the convenient replacement of the core sleeve 53; after replacement, the translation mechanism 40 abuts the core rod mechanism 50 against the holding mechanism 30, and rotates under the drive of the rotary mechanism 20 to realize the winding action; after winding is completed, the guide mechanism 60 abuts against the spring, and the translation mechanism 40 moves the core rod mechanism 50 away, so that the core rod can fall automatically.
[0038] It should be noted that the specific models and specifications of the rotary motor 22, clamping motor 36, translation motor 43 and electric cylinder 62 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
[0039] The power supply and operating principle of the rotary motor 22, clamping motor 36, translation motor 43 and electric cylinder 62 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, improvements, or equivalent substitutions made within the spirit and principles of this application should be included within the scope of protection of this application.
