Technical Field

[0001] The present application relates to the technical field of spring processing, and in particular to a spring forming device. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. It can deform when subjected to external force, but can return to its original shape when the external force disappears. This recovery property is called elasticity, which is one of the most basic properties of a spring.

[0003] During the manufacturing process of some springs, operators need to squeeze the steel wires at both ends of the springs so that the steel wires at both ends of the springs are deformed due to stress, thus forming into a hook shape.

[0004] The above-mentioned method of manually squeezing the steel wires at both ends of the spring to form the spring has high labor costs and is time-consuming and labor-intensive, resulting in low production efficiency. Summary of the invention

[0005] In order to help solve the problem of manually squeezing the steel wires at both ends of the spring to form the spring, which has high labor costs and is time-consuming and labor-intensive, resulting in low production efficiency, the present application provides a spring forming device, which adopts the following technical solution: it includes a support arranged at the stamping end of the stamping machine and a support plate arranged on the workbench of the stamping machine, the support plate is provided with a fixing component for limiting the spring, and the support is provided with an extrusion component for extruding the spring.

[0006] Through the above technical solution, when it is necessary to bend the steel wire at the end of the spring into a hook shape, the punching machine is started to drive the support at the punching end of the punching machine to be pressed down, and the spring end is squeezed by the extrusion component so that the steel wire at the end of the spring is squeezed into a hook shape. The position of the spring is limited by the fixing component to reduce the possibility of the spring being offset by force. The extrusion component and the fixing component are used to reduce labor costs, save time and effort, and improve production efficiency.

[0008] Through the above technical solution, the pad supports the base, and the first limit groove and the second limit groove limit the position of the spring, thereby reducing the possibility of the spring being forced to pop out of the base during the stamping process of the punching machine and improving the stability of the hook-shaped forming of the spring end.

[0009] In a specific possible implementation manner, the extrusion assembly includes a tool holder arranged at the outer edge of the pillar, and a punching knife is provided at one end of the tool holder facing the base, and the end of the punching knife facing the base corresponds to the end of the spring.

[0010] Through the above technical solution, the punching machine is started to drive the support at the punching end of the punching machine to press down, so that the punching knife squeezes the end of the spring, so that the end of the spring is forced to form into a hook shape.

[0011] In a specific implementation scheme, a slide groove is provided on the outer edge of the pillar, a slider matching the slide groove is provided on the surface of the tool holder facing the slide groove, the slider is slidably connected in the slide groove, and a limiting unit for fixing the position of the tool holder is provided on the pillar.

[0012] Through the above technical solution, the slider slides along the slide groove, so that the position of the tool holder relative to the support can be adjusted. After adjustment, the position of the tool holder is fixed by the limit unit, thereby improving the flexibility of the tool holder position.

[0013] In a specific possible implementation scheme, the limiting unit includes a fixing bolt that passes through and is threadedly connected to the tool holder, and one end of the fixing bolt that faces the support column is tightly pressed against the bottom of the slide groove.

[0014] Through the above technical solution, when the tool holder is moved to a suitable position, the fixing bolt is rotated so that one end of the fixing bolt facing the support is pressed against the bottom of the slide slot, thereby fixing the position of the tool holder.

[0015] In a specific feasible implementation scheme, a knife seat corresponding to the knife holder is provided on the support plate, a stamping seat is provided on the surface of the knife seat facing the pillar, a knife groove matching the stamping knife is opened on the surface of the stamping seat facing the pillar, and the end of the spring is pressed between the stamping knife and the bottom of the knife groove.

[0016] Through the above technical solution, the punching machine is started, which drives the support at the punching end of the punching machine to be pressed down, thereby driving the punching knife to be pressed down, so that the end of the spring is pressed tightly between the punching knife and the bottom of the knife groove. The knife groove has a limiting effect on the steel wire at the end of the spring, so that the hook shape formed by the end of the spring after being extruded is basically consistent, thereby improving the quality of the spring hook-shaped forming.

[0017] In a specific possible implementation manner, a mounting groove matching the punching knife is provided on the surface of the knife holder facing the base, and the punching knife is partially inserted into the mounting groove.

[0018] Through the above technical solution, the punching knife is partially inserted into the installation groove, which facilitates the subsequent replacement of the punching knife and has greater flexibility.

[0019] In a specific implementation scheme, the support plate is provided with a plurality of mounting bolts, the workbench of the punching machine is provided with a plurality of bolt grooves matching the plurality of mounting bolts, and the ends of the plurality of mounting bolts facing the workbench of the punching machine are respectively threadedly connected in the plurality of bolt grooves.

[0022] Through the above technical solution, the arc-shaped groove reduces the possibility of debris accumulation after the spring is stamped in the first limiting groove, which facilitates the subsequent cleaning of the first limiting groove.

[0023] In a specific possible implementation manner, the second limiting groove is an arc-shaped groove.

[0024] In summary, the present application has at least the following beneficial technical effects: when it is necessary to bend the steel wire at the end of the spring into a hook shape, start the punching machine to drive the support at the punching end of the punching machine to be pressed down, and squeeze the end of the spring through the extrusion assembly so that the steel wire at the end of the spring is forced into a hook shape, and limit the position of the spring through the fixing assembly to reduce the possibility of force displacement of the spring, and use the extrusion assembly and the fixing assembly to reduce labor costs, save time and effort, and improve production efficiency.
