Description

Technical Field

[0001] This application belongs to the technical field of spring processing equipment structure, specifically relating to a spring machine and its working method. Background Technology

[0002] A spring forming machine is a specialized piece of machinery used for processing spring steel wire and forming springs of various specifications. It is widely used in hardware, auto parts, precision instruments, and other fields. Existing conventional spring forming machines have a relatively fixed structural design. Their wire feeding assembly and equipment panel are integrated into a single unit, meaning the wire feeding assembly is fixedly integrated onto the equipment panel and cannot be independently disassembled or moved for adjustment. Simultaneously, multiple sets of cutting tools used for spring cutting, shaping, and bending are directly fixedly installed in preset positions on the equipment panel.

[0003] This traditional structure has many inherent drawbacks in practical production applications. On the one hand, the integrated structure limits the adjustment dimensions of the tool assembly. The tool assembly is fixed to the equipment panel, allowing only single-direction or small-range fine-tuning. It cannot adjust the position and stroke in multiple directions and angles according to the needs of spring products with different specifications and forming processes. This results in poor equipment adaptability and difficulty in meeting the precision processing requirements of irregularly shaped and high-precision springs. On the other hand, traditional spring machines require additional angle bending tools to accommodate multi-angle bending and forming processes. This not only increases the number of parts and assembly steps, raising the costs of production, assembly, and maintenance, but also makes the overall structure bulky due to the additional parts occupying internal space. Furthermore, angle bending tools are prone to wear, misalignment, and jamming with prolonged use, reducing the overall stability and processing accuracy of the equipment. Repairing faults and replacing parts further increases downtime costs and affects the production efficiency of spring processing. Therefore, a solution to these problems is urgently needed. Summary of the Invention

[0027] The following is in conjunction with the appendix Figures 1-8 The present application will be further described in detail with reference to specific implementation methods, but this is not intended to limit the present application.

The processing structure and the wire feeding structure 200 are separately arranged. The processing structure includes a movable frame 1, a tool assembly 2, and a drive assembly 3. The drive assembly 3 is used to provide power for the movement of the movable frame 1 in the Y-axis direction A. The movable frame 1 includes a panel 11 with a through-hole processing hole 111. The tool assembly 2 is provided in one or more sets. The panel 11 has a first surface 112 and a second surface 113 arranged opposite to each other.

[0029] In practical applications, the spring machine in this embodiment adopts a separate layout design for the wire feeding structure 200 and the processing structure. The panel 11, which carries the tool assembly 2, can be adjusted in the Y-axis direction A through the drive assembly 3. This allows for multi-directional position and stroke adjustment of the tool assembly 2, adapting to the production needs of springs with different forming structures and improving the processing flexibility of the equipment. Simultaneously, through the combination of the separate structure and the movable panel 11, this application can directly complete the entire set of processing steps, including multi-angle bending, shaping, and cutting of springs, without the need for the corner bend auxiliary structure of traditional equipment. This simplifies the overall component configuration and assembly process, effectively reducing the comprehensive costs of equipment manufacturing, assembly, debugging, and subsequent maintenance. Furthermore, it avoids the wear, misalignment, and jamming problems caused by long-term use of corner benders, reducing the probability of equipment downtime and ensuring the continuity and stability of spring processing production.

[0030] Meanwhile, in this embodiment, the movable frame 1 including the panel 11 can move as a whole on the Y-axis and is set separately from the wire feeding structure 200, which ensures the stability of the movement of the tool assembly 2 on the panel 11. At the same time, the wire feeding structure 200 is fixedly set on the base 300, which increases the stability of the entire spring machine operation and reduces the possibility of accidents during spring processing.

[0031] Specifically, the base frame includes a first base side plate 41, a second base side plate 42, a first stop bar 43, and a second stop bar 44 fixed to the top surface of the base 300.

The second stop bar 44 is arranged close to the tool assembly 2. A baffle 45 is provided at the end of the first base side plate 41 and the second base side plate 42 away from the panel 11. The two ends of the baffle 45 are respectively connected to the first base side plate 41 and the second base side plate 42.

[0032] In this embodiment, two baffles 45 are provided to prevent the movement of the movable frame 1 from exceeding the set stroke. The number and position can be modified according to actual needs without specific settings.

The first movable side plate 13 and the second movable side plate 14 are respectively equipped with a first slider 15 and a second slider 16. The first base side plate 41 and the second base side plate 42 are respectively equipped with a first guide rail 17 and a second guide rail 18. The first slider 15 is sleeved on the first guide rail 17, and the second slider 16 is sleeved on the second guide rail 18. Both ends of the panel 11 are respectively provided with clearance openings 114 configured for the passage of the first guide rail 17 and the second guide rail 18.

[0034] In this embodiment, the cooperative use of the first guide rail 17 and the first slider 15, as well as the cooperative use of the second slider 16 and the second guide rail 18, plays a guiding role and further ensures the accuracy of the panel 11 when it moves. There are two of each of the first guide rail 17 and the second guide rail 18, which can ensure the parallelism of the panel 11 when it moves. It can be understood that the number of the first guide rail 17 and the second guide rail 18 can be changed according to actual needs.

[0035] Specifically, the movable base plate 12 is provided with a third slider 19, the top surface of the base frame is provided with a third guide rail 5, the third slider 19 is sleeved on the third guide rail 5, the movable base plate 12 is provided with a mounting hole 121 and an inclined groove 122, the mounting hole 121 is configured such that the fixing bracket 6 passes through the mounting hole 121 and is fixedly installed on the top surface of the base frame, the length of the mounting hole 121 in the Y-axis direction A is greater than the length of the fixing bracket 6 in the Y-axis direction A; the inclined groove 122 is used to provide moving space for the tool assembly 2 located near the inclined groove 122.

[0036] In this embodiment, four third guide rails 5 are provided to further ensure the parallelism of the panel 11 when it moves. It is understood that the number of third guide rails 5 can be changed according to actual needs.

[0038] Understandably, the installation of mounting hole 121 and the installation method of fixing side plate 62, while not affecting the separate setting of processing structure and wire feeding structure 200 and the smooth processing of spring, result in a compact structure and improved space utilization.

[0039] Specifically, the drive assembly 3 includes a drive element 31, a moving shaft 32, and a moving block 33. The moving shaft 32 is installed at the output end of the drive element 31, and the moving block 33 is sleeved on the moving shaft 32.
