Abstract
Description
- The present invention in general relates to an abutting apparatus, in particular, to an abutting apparatus of a spring manufacturing machine.
- According to the prior art, common spring manufacturing machines all have a so-called abutting apparatus adapted for forming a wire into the configuration of a coil spring by means of abutment with a wire forming tool. During the process of forming a coil spring or curled spring, wire is fed into the spring manufacturing machine via a feeding mechanism; in the meantime, an abutting apparatus is adapted for curling the wire into a spring, in particular a coil spring; finally, a cutting knife apparatus is applied to cut off the wire to complete the procedure of manufacturing a coil spring or curled spring. During the process, the function of the abutting apparatus is to curl a linear wire into a curled spring by abutment with a wire forming tool. According to common practices, a spring manufacturing machine usually has two abutting assemblies arranged corresponding to each other at two sides thereof. By adjusting the positions of these two abutting assemblies it is possible to properly adjust the magnitude of the radius of the coil spring.
- According to the prior art, the abutting apparatus of a spring manufacturing machine usually includes a sliding seat and an abutting unit connected to be slidable on the sliding seat, such that the abutting unit can make a 1-D linear movement in an oblique direction relative to the spring manufacturing machine, whereby the magnitude of the radius of the manufacture coil spring can be adjusted. However, with such an abutting apparatus not only the degree of freedom is insufficient, but also it is uneasy for the purpose of adjustment, when a 1-D linear movement is used to adjust the obliqueness relative to the spring manufacturing machine and to thereby properly adjust the magnitude of the radius of the coil spring to be manufactured.
- Therefore, another kind of abutting apparatus for a spring manufacturing machine has been developed, in which not only the abutting unit can make an oblique motion relative to the spring manufacturing machine, but the abutting apparatus can also make a vertically linear motion in one dimension relative to the spring manufacturing machine. However, this kind of linear movement in two directions is still inadequate to adjust the positions of the abutting unit. In this prior art, the abutting unit can only make a small adjustment of the position relative to the spring manufacturing machine. Besides, the two abutting units of the spring manufacturing machine can also make two independent 2-D motions, whereby the positions of the abutting units relative to the wire feeding axle of the spring manufacturing machine can be adjusted at random, which indeed causes an inadequate flexibility in terms of the process of manufacturing a coil spring.
- Accordingly, after a substantially devoted study, in cooperation with the application of relative academic principles, the inventor has finally proposed the present invention designed reasonably to possess the capability to improve the drawbacks of the prior arts significantly.
- Therefore, in order to solve aforementioned problems, a primary objection of the present invention is to provide an improved abutting apparatus of a spring manufacturing machine. Via a first and second axial transmission mechanisms, the abutting assembly can be randomly moved in vertical and/or horizontal directions relative to the machine platform, such that the degree of freedom to adjust the abutting assembly can be enhanced significantly.
- A second objective of the present invention is to provide an improved abutting apparatus of a spring manufacturing machine, in which the spring manufacturing machine has a machine platform, while the abutting apparatus comprises a fist and second axial transmission mechanism and an abutting assembly. The first axial transmission mechanism comprises a first actuator, a first lead screw driven by the first actuator to rotate and a first sliding seat engaging with the first lead screw and being capable to perform a linear movement relative to the machine platform. The second axial transmission mechanism comprises a second actuator fixed to the first sliding seat, a second lead screw driven to be rotated by the second actuator and a second sliding seat engaging with the second lead screw and being configured to be moved linearly relative to the first sliding seat. Via the first and second axial transmission mechanisms, the abutting assembly fixed to the second sliding seat can perform a 2-D movement in vertical and/or horizontal directions relative to the machine platform as desired and in accordance with the geometrical configuration of the coil spring to be manufactured.
- According to another embodiment the present invention provides an abutting apparatus of a spring manufacturing machine, in which the spring manufacturing machine has a machine platform and a spring wire feeding axle, while the abutting apparatus comprises a pair of first axial transmission mechanisms, a pair of second axial transmission mechanisms and a pair of abutting assemblies. The pair of first axial transmission mechanisms, which are respectively formed at an upper and lower sides of a central line of the spring wire feeding axle, are of substantially identical configuration and each comprises a first actuator fixed to the machine platform, a first lead screw driven by the first actuator to rotate and a first sliding seat engaging with the first lead screw and being capable to perform a linear movement relative to the machine platform. Each of the pair of second axial transmission mechanisms comprises a second actuator fixed to the first sliding seat, a second lead screw driven to rotate by the second actuator and a second sliding seat engaging with the second lead screw and linearly moved relatively to the first sliding seat. Via the pair of first axial transmission mechanisms and the pair of second transmission mechanisms, the pair of abutting assemblies respectively fixed to the second sliding seat can independently make a 2-D movement in vertical and horizontal directions relative to the machine platform.
- In comparison with the prior art, the invention accomplishes in particular the following functions and advantages. Firstly, the drawback of the spring manufacturing machines according to the prior art, according to which the abutting apparatus can only be adjusted by a linear movement in a single direction, can be overcome according to the present invention by an arbitrarily adjustable 2-D movement in vertical and/or horizontal directions, so that according to the present invention the positions of the abutting assemblies can be conveniently adjusted relative to the machine platform and the spring wire feeding axle to enhance the flexibility in the spring manufacturing process. Secondly, since the pair of abutting assemblies can be moved independently and simultaneously to thereby enable many different directions of movement, coil springs with a more complicated 3-D configuration can be manufactured. Thirdly, the first and second transmission mechanisms can enhance the variability of the locations and angles of the movement of the abutting assemblies. Fourthly, since the first and second axial transmission mechanisms can be moved in a linear motion, according to the present invention a more accurate positioning can be achieved and it is easier in terms of operation. Finally, the movement of the pair of abutting assemblies can be respectively and independently controlled by using a computer, so that according to the present invention the flexibility in manufacturing the spring can be enhanced significantly and the difficulty of configuration can be also lowered down in great scale.

Fig. 1 andFig. 2 , which respectively are a perspective outer view of the abutting apparatus according to the present invention and a perspective outer view from another viewing angle of the abutting apparatus according to the present invention. The invention is to provide anabutting apparatus 2 of a spring manufacturing machine, wherein thespring manufacturing machine 1 has amachine platform 10 and a spring wire feeding axle 11 (as shown inFig. 8 ). Theabutting apparatus 2 includes a pair of firstaxial transmission mechanisms 20, a pair of secondaxial transmission mechanisms 30 and a pair of abuttingassemblies 40 configured to curl a linear metal wire into a curled spring or coil spring by means of abutment of the wire against a wire forming tool. - The pair of first
axial transmission mechanisms 20 are respectively formed at an upper and lower side of a central line of the springwire feeding axle 11 and are of substantially identical configuration. In the meantime, the firstaxial transmission mechanism 20 includes afirst actuator 21 fixed to themachine platform 10, afirst lead screw 22 driven by thefirst actuator 21 to rotate and a first slidingseat 23 connected to thefirst lead screw 22 and able to make a linear movement relative to themachine platform 10. - The pair of second
axial transmission mechanisms 30 are of substantially identical configuration and respectively include asecond actuator 31 fixed to the first slidingseat 23, asecond lead screw 32 driven by thesecond actuator 31 to rotate and a second slidingseat 33 connected to thesecond lead screw 32 and can make a linear movement relative to the first slidingseat 23. - The pair of
abutting assemblies 40 are respectively fixed to the second sliding seat. Via the firstaxial transmission mechanism 20 and the secondaxial transmission mechanism 30, theabutting assembly 40 can perform vertical and horizontal movements, in particular linear movements in vertical and horizontal directions, relative to themachine platform 10. In addition, theabutting assembly 40 includes afixing seat 41 fixed to the second slidingseat 33 and an abuttingtelescopic rod 42 screwed with thefixing seat 41, such that the abuttingtelescopic rod 42 can make an oblique movement relative to the second slidingseat 33 to adjust the position thereof: - Furthermore, the
first actuator 21 and thesecond actuator 31 can be a stepping motor or a servo motor; however, the present invention shall not be limited to these two kinds of exemplary embodiments only. - Please refer to
Fig. 3 andFig. 4 , which respectively are a perspective view (1) and a perspective view (2) of the abutting apparatus according to the present invention. Please study these drawings together withFig. 2 . The first slidingseat 23 includes afirst plate body 231 and afirst nut 232 connected fixedly to thefirst plate body 231 and screwed with thefirst lead screw 22 correspondingly. - The second sliding
seat 33 includes asecond plate body 331 and asecond nut 332 connected fixedly to thesecond plate body 331 and screwed with thesecond lead screw 32 correspondingly. - In addition, the first sliding
seat 23 further includes a first slidingblock 233 fixed to thefirst plate body 231 and located at the same side of thefirst nut 232. The first slidingblock 233 is provided with a first slidingslot 2331. Themachine platform 10, in the meantime, has aslide 12. The first slidingslot 2331 is configured for theslide 12 to be slid and inset therein. - The first sliding
seat 23 also includes afirst slide 234 connected fixedly to another side of thefirst plate body 231. The second slidingseat 33 includes a second slidingblock 333 fixed to thesecond plate body 331 and located at the same side of thesecond nut 332. The second slidingblock 333 is provided with a second slidingslot 3331 configured for thefirst slide 234 to be inset therein. - Please refer to
Fig. 5 andFig. 6 , which respectively are an actuating illustration (1) and an actuating illustrate (2) by viewing from the front of the abutting apparatus according to the present invention. By moving the firstaxial transmission mechanism 20 relative to themachine platform 10, the abuttingassembly 40 can be moved vertically. By moving the secondaxial transmission mechanism 30 relative to the firstaxial transmission mechanism 20, the abuttingassembly 40 can be moved horizontally. By so doing, the abuttingassembly 40 can be moved in a 2-D rectangular coordinate system. The degree of freedom to adjust the abuttingassembly 40 can be thus enhanced. - More specifically, the pair of abutting
assemblies 40 can be moved independently in a 2-D rectangular coordinate system. For example, when processing a linear metal wire to form a curled spring or a coil spring, the abuttingassembly 40 is directed towards the spring wire feeding axle 11 (as shown inFig. 8 ) and only performs a horizontal movement relative to the springwire feeding axle 11 without any vertical movement. On the other hand, the abuttingassembly 40 located above the springwire feeding axle 11 then can perform a horizontal, vertical or oblique movement. An "oblique movement" mentioned here means that the tracks of the abuttingassembly 40 can be linear or curved, including an are-shaped or parabola-shaped course of the guiding tracks. - Moreover, via the simultaneous actuations of the first
axial transmission mechanism 20 and the secondaxial transmission mechanism 30, the abuttingassembly 40 can be moved obliquely so that the wire forming tools can finally get into abutment with the linear metal wire to be curled to the desired coil spring. In other words, the movement of the abuttingassembly 40 can be controlled at random, in accordance with the shape of the coil spring to be manufactured. For example, if the proportion between the rightward movement of the second slidingseat 33 and the upward movement of the first slidingseat 23 is 1:1, then the abuttingassembly 40 will be moved to the right with a lifting angle of 45 degrees. If the proportion is 1: √3, then the abuttingassembly 40 will be moved to the right with a lifting angle of 60 degrees. As will become apparent to a person skilled in the art, by means of the above configuration an arbitrary 2D-movement of the abuttingassembly 40 can be achieved, which significantly enhances the degree of freedom in manufacturing coil springs. - Please refer to
Fig. 7 , which is illustrates possible exemplary movements of the abutting assemblies in an abutting apparatus of the present invention. As shown in this figure, the abuttingassembly 40 located above the spring wire feeding axle 11 (as shown inFig. 8 ) is moved obliquely, while another abuttingassembly 40 directed towards the springwire feeding axle 11 is moved horizontally. - Please refer to
Fig. 8 andFig. 9 , showing two front views according to one preferred embodiment of the present invention. As shown in these two figures, a pair of firstaxial transmission mechanisms 20 and a pair of secondaxial transmission mechanisms 30 are arranged at an upper and lower side of the springwire feeding axle 11, respectively. By moving the firstaxial transmission mechanisms 20 relatively to themachine platform 10 and moving the secondaxial transmission mechanisms 30 relatively to the firstaxial transmission mechanism 20, the position of the abuttingassembly 40 can be changed, such that the magnitude of the radius of the configuredspring 50 can be determined and properly adjusted. - Please refer to
Fig. 10 through Fig. 12 , which separately are a perspective outer view, an actuation status illustration (1) and an actuation status illustration (2) of a cross-sectional view along the line "11-11" inFig. 10 according to another preferred embodiment of the present invention. In this embodiment, the abuttingassembly 40' includes a wire configuration knife seat 41', awire configuration knife 42' pivoted to the wire configuration knife seat 41' and a driving block 43'. - The wire configuration knife seat 41' is fixed to the second sliding
seat 33, while the driving block 43' is fixed onto the machine platform 10 (not shown in the figures) and abutted against one side of thewire configuration knife 42'. In this case, when the wire configuration knife seat 41' fixed to the second slidingseat 33 is moved relatively to the driving block 43', thewire configuration knife 42' can be swung relatively to the wire configuration knife seat 41'. - More specifically, one side of the
wire configuration knife 42' is arranged abearing 421'. The driving block 43' is arranged a lead slot 431' that is shown as an oblique configuration and provided for thebearing 421' to be slid therein. The relative movement between the second slidingseat 33 and themachine platform 10 can make thewire configuration knife 42' moved upwardly and downwardly in a third axial direction. Since thewire configuration knife 42' is swung in a third axial direction, a collision phenomenon can be avoided when the spring is configured by being fed out from the spring wire feeding axle 11 (as shown inFig. 9 ). - Therefore, through the constitution of aforementioned assemblies, an abutting apparatus of a spring manufacturing machine according to the present invention is thus obtained.
- Summarizing the aforementioned description, the abutting apparatus according to the present invention is an indispensable component for a spring manufacturing machine indeed, which may positively reach the expected usage objective for solving the drawbacks of the prior arts, and which extremely possesses the innovation and progressiveness to completely fulfill the applying merits of a new type patent, according to which the invention is thereby applied. Please examine the application carefully and grant it as a formal patent for protecting the rights of the inventor.
