Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring steel wire torsion forming device. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. It is made of elastic material and deforms under the action of external force. It returns to its original shape after the external force is removed. It is generally made of spring steel wire. There are many types of springs. According to their shape, they mainly include coil springs, scroll springs, etc.

[0003] Torsion spring is also called torsion spring, which is a cylindrical helical spring that bears torsion torque. It uses the principle of lever to twist or rotate the soft and tough elastic material to give it great mechanical properties.

[0004] When current springs are made using a torsion forming device, the torsion forming device lacks a limited feeding measure, so that the springs need to be fed manually during production, which is dangerous and has a poor spring production effect. In addition, after the current torsion forming device is used to make the spring, it is not convenient to remove the finished spring. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a spring wire twisting forming device to solve the problems of the prior art that manual feeding is required, it is inconvenient to remove the manufactured springs, and the efficiency is low.

[0006] In order to achieve the above purpose and other related purposes, the utility model provides the following technical solutions:

[0007] A spring steel wire torsion forming device comprises a wire-releasing device, a torsion device and a shearing device, a material-blocking device is further provided on the side opposite to the wire-releasing device, and a material-blowing device is provided on the torsion device; the wire-releasing device comprises a straightening assembly and a straightening drive device for driving the straightening assembly to move; the straightening assembly comprises a mounting plate, a plurality of upper rollers arranged on the mounting plate, a plurality of lower rollers corresponding to the upper rollers and a wire-passing hole for passing the steel wire; the straightening drive device comprises a bottom plate, a slide rail arranged on the bottom plate, a vertical plate arranged on the bottom plate and at the end opposite to the mounting plate, a straightening cylinder is slidably provided on the slide rail, a piston rod of the straightening cylinder is arranged on the vertical plate, and the mounting plate is arranged on the body of the straightening cylinder.

[0008] To implement the above technical solution, during use of the present application, after the steel wire is straightened by the straightening assembly, it extends out from the wire hole and is twisted and formed by the twisting device. The straightening assembly can move along the slide rail under the drive of the straightening drive device to form the length of the spring steel wire. After the spring steel wire is twisted and formed, the shearing device will cut the steel wire, and then the blowing device will blow the formed spring steel wire off the twisting and forming device, thereby facilitating the processing of the next spring steel wire.

[0009] In one embodiment of the utility model, the shearing device includes a mounting seat, a lower cutter arranged on the mounting seat, an upper cutter hingedly arranged with the lower cutter, and a shearing cylinder driving the upper cutter to rotate along the lower cutter.

[0010] To implement the above technical solution, the shearing cylinder in the present application can drive the upper cutter to approach or move away from the lower cutter, thereby completing the shearing of the spring wire after torsion forming.

[0011] In one embodiment of the utility model, the end of the lower cutter is mounted on the mounting seat via a cutter plate, the cutter plate is hinged with an arc-shaped connecting rod via a pin shaft, the middle of the arc-shaped connecting rod is provided with the upper cutter, and the other end of the arc-shaped connecting rod is hinged with a push rod of the shear cylinder.

[0012] To implement the above technical solution, during use, the push rod of the shearing cylinder is hinged at the upper end of the arc-shaped connecting rod. When the push rod of the shearing cylinder is extended, the arc-shaped connecting rod can rotate along the pin shaft and drive the upper cutter to approach the lower cutter, thereby completing the shearing of the spring steel wire after the twisting is completed; the push rod of the shearing cylinder contracts, thereby making the upper cutter move away from the lower cutter, thereby avoiding the processing of the next spring steel wire.

[0013] In one embodiment of the present invention, the twisting device includes a twisting motor, a forming rod arranged on the output shaft of the twisting motor, and a support seat arranged at the lower end of the twisting motor.

[0014] To implement the above technical solution, during use, the rotation speed of the torsion motor needs to be in sync with the movement of the mounting plate to ensure that the gaps between the spring steel wires are uniform and not too large. During use, the ends of the steel wires are limited by the abutment of the steel wires in the abutment device, and the steel wires are twisted and formed by the rotation of the forming rod.

[0015] In one embodiment of the present invention, the material resisting device includes a material resisting block and a material resisting opening formed on the material resisting block.

[0016] To implement the above technical solution, the material abutment opening is used to abut against the steel wire, and is used to control the extended length of the spring end, so as to facilitate the forming of the spring steel wire.

[0017] In one embodiment of the utility model, the blowing device includes a blowing valve and a blowing nozzle arranged on the blowing valve, and the blowing nozzle is arranged obliquely and aligned with the forming rod.

[0018] To implement the above technical solution, after the wire spring is twisted and formed, the blowing nozzle is aimed at the forming rod and blows the formed spring off the forming rod.

[0019] As described above, a spring steel wire torsion forming device of the utility model has the following beneficial effects: during use of the application, the steel wire is straightened by the straightening assembly, then extends out from the wire hole, and is twisted and formed by the twisting device. The straightening assembly can move along the slide rail under the drive of the straightening drive device to form the length of the spring steel wire. After the spring steel wire is twisted and formed, the shearing device will cut the steel wire, and then the blowing device will blow the formed spring steel wire off the twisting and forming device, thereby facilitating the processing of the next spring steel wire. The application uses automated processing, has high efficiency, and has a good spring forming effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] During use of the present application, after the steel wire is straightened by the straightening assembly, it extends out from the wire hole 4 and is twisted and formed by the twisting device. The straightening assembly can move along the slide rail 6 under the drive of the straightening drive device to form the length of the spring steel wire. After the spring steel wire is twisted and formed, the shearing device will cut the steel wire, and then the blowing device will blow the formed spring steel wire off the twisting and forming device, thereby facilitating the processing of the next spring steel wire.

[0028] The shearing device includes a mounting seat 9, a lower cutter 10 disposed on the mounting seat 9, an upper cutter 11 hingedly disposed with the lower cutter 10, and a shearing cylinder 12 driving the upper cutter 11 to rotate along the lower cutter 10. In the present application, the shearing cylinder 12 can drive the upper cutter 11 to approach or move away from the lower cutter 10, thereby completing the shearing of the spring steel wire after twisting and forming.
