Description

TECHNICAL FIELD

[0001] The present application relates to the field of spring manufacturing, in particular to a hot coil spring shaping device. BACKGROUND

[0002] The hot coil spring is also known as large spring, because the diameter of the spring is generally large, and the diameter of some hot coil springs reaches 20 cm. The production process adopts hot coil process. The typical process of hot coil spring is: blanking---end processing (flattening or flattening)---heating---spring winding---quenching---tempering---end surface grinding---compression--- (load test)---shot blasting (cleaning)---coating. During the processing of the spring, the spring needs to be positioned for subsequent processing, and the stability of the spring needs to be maintained during the processing of the spring. At present, the hot coil wire needs to be clamped and transported for positioning by manual or semi-manual operation, and there is no reliable spring stability measure. Such operation is not only rough and imprecise, but also cannot meet the automatic control of spring height / relative height, and is not suitable for automatic design and development, and is also low in efficiency. It is often necessary for people to contact the heated steel wire, and the working environment is poor. If the operation is not proper, it is also easy to cause danger. Therefore, it is necessary to find a way or method to automatically support and position the hot coil spring in the automatic process. SUMMARY

[0003] Therefore, it is necessary to overcome at least one of the above defects in the prior art. The present application provides a spring shaping device, which comprises a base plate, an X-axis movement mechanism mounted on the base plate, the X-axis movement mechanism comprising an X-axis sliding mechanism, a horizontal fine adjustment cylinder group mounted on the X-axis sliding mechanism, the horizontal fine adjustment cylinder group comprising a plurality of horizontal fine adjustment cylinders, the output end of the horizontal fine adjustment cylinder being connected with a spring center shaft shaping and positioning mechanism, the rotating shaping and positioning mechanism comprising a mold head for shaping and positioning the spring center shaft, the mold head being connected with a driving mechanism for moving the mold head to the spring center shaft for shaping and positioning.

[0004] According to the prior art in the background art of the present patent, in the process of positioning and stabilizing the spring, the prior art also needs to use artificial or semi-artificial operation, which brings random roughness, inaccuracy, low efficiency, difficulty in automation, and poor working environment due to the need for human contact with heated steel wire. If the operation is not proper, it is also easy to cause danger. The spring shaping device disclosed in the present application can insert the mold head into the inside space of the spring fixed by external force through automatic control, support the inside of the spring with the profiling surface of the outer edge of the mold head. In order to achieve better results, multiple mold heads can be used to support the inside of the same spring. The detachable mold head makes the entire device applicable to springs of various specifications, thereby realizing the positioning and stabilization of springs of various specifications, improving the degree of automation, and improving the production efficiency and safety. During the process of inserting the mold head into the inside of the spring, the mold head is first pushed from the side of the supporting rod by the push cylinder and rotated between the spring coils to form a state in which the outer edge of the mold head can be attached to the inner wall of the spring. Then, the horizontal fine adjustment cylinder pushes the mold head into the spring inner ring, so that the mold head outer edge and the spring inner wall can be attached and have a certain supporting force. In this way, the stability of the spring as a whole is maintained during the curling process at the tail end of the spring, thereby preventing the spring from deforming.

[0005] When the spring is placed in the predetermined position, the mold head is brought to the first predetermined position by the X-axis movement mechanism. This position is such that the mold head can enter the inside of the spring through the gap between the spring coils. Then, the mold head is rotated or pushed into the inside of the spring by the push cylinder. Due to the action of the limiting part, the profiling surface of the mold head and the inner wall of the spring can be in a matching position. At this time, the horizontal fine adjustment cylinder pushes the mold head forward or backward to contact the spring inner wall, which plays the role of supporting the mold head on the inside wall of the spring. In this way, the rigidity of the spring can be improved, and the stability during the subsequent processing process can be maintained, thereby improving the yield rate in the previous processing process.

[0006] In addition, the spring shaping device disclosed in the present application also has the following additional technical features:

[0007] Further, the driving mechanism is a push cylinder for pushing the mold head to the center axis of the spring for shaping and positioning. The push cylinder and the mold head are installed on a sliding assembly provided on the X-axis sliding mechanism.

[0008] Further, the driving mechanism is a push cylinder installed on a sliding member in the sliding assembly provided on the X-axis sliding mechanism. The push cylinder is connected to one end of a rotating plate installed on the sliding member. The other end of the rotating plate is connected to the mold head. The rotating plate is connected to a rotating part on the sliding member through the connection of the middle part of the rotating plate and the rotating part.

[0009] Further, the rotating plate comprises a first rotating plate, one end of which is connected with the pushing cylinder and the other end of which is connected with the mold head through a connecting mechanism.
