Description

Technical Field

[0001] The utility model relates to a spring wire straightening device with stable structure, belonging to the technical field of straightening devices. Background Art

[0002] A straightening device is a device for straightening metal bars, pipes, wires, etc. The straightening machine extrudes the bars, etc. through straightening rollers to change their straightness. Generally, there are two rows of straightening rollers with different numbers. There is also a two-roller straightening machine that straightens materials with different diameters by changing the angles of the two rollers (concave in the middle, hyperbolic rollers).

[0003] A wire straightening device for spring wire with the Chinese patent number CN218611437U includes a bracket and a bottom plate fixed on the bracket. A vertical plate is provided on the bottom plate. A plurality of fixed wheels and a plurality of straightening wheels are provided on one side of the vertical plate. The wire straightening device for spring wire can straighten the bent wire during use, convey it simultaneously during the straightening process, and can also polish and remove rust from the circumference of the wire when the straightening is completed, further improving the quality of the wire, and is suitable for popularization and use.

[0004] During the straightening process, debris on the outer wall of the wire body to be processed may adhere to the outer wall surface of the straightening roller wheels. If not cleaned in time, it will affect the subsequent straightening operation, and manual cleaning is time-consuming, laborious and inefficient.

[0005] Therefore, a spring wire straightening device with stable structure is proposed. Content of the Utility Model

[0006] In view of this, the utility model provides a spring wire straightening device with stable structure to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial choice.

[0007] The technical solution of the utility model is realized as follows: A spring wire straightening device with stable structure includes an operation chassis. A second straightening backboard is fixedly connected to the upper left side of the operation chassis, and a first straightening backboard is fixedly connected to the upper right side of the operation chassis. A plurality of pairs of straightening roller wheels are installed on the outer ends of the first straightening backboard and the second straightening backboard. A strip-shaped slot is opened in the middle of the sides of the second straightening backboard and the first straightening backboard close to the straightening roller wheels. An electric push rod is fixedly connected to the inner side wall of the strip-shaped slot. The output end of the electric push rod is fixedly connected to a U-shaped cross bar. Electric rotating shafts are symmetrically fixedly connected to the left and right ends of the U-shaped cross bar. A connecting cross bar is installed between the two electric rotating shafts. Sponge pairs are fixedly connected to the left and right ends of the connecting cross bar.

[0008] Further preferably, the wire body to be processed passes through between multiple pairs of straightening roller wheels, and the sponge pairs extend to the outside of the strip-shaped slot.

[0009] Further preferably, the steel wire body to be processed passes through the first correction back plate and the second correction back plate in sequence.

[0010] Further preferably, the sponge strips cooperate with the correction rollers, and the right end of the first correction back plate is fixedly connected with a side vertical slide groove.

[0011] Further preferably, a damping slider is installed at the inner end of the side vertical slide groove, and a round hole roller is fixedly connected to one end of the damping slider close to the steel wire body to be processed.

[0012] Further preferably, a plurality of rubber triangular pieces are fixedly connected to the inner side wall of the circular hole roller shaft, and the plurality of rubber triangular pieces are arranged in a ring shape.

[0013] Further preferably, the steel wire body to be processed passes through the inside and outside of the circular hole roller, and the steel wire body to be processed cooperates with the rubber triangle piece.

[0014] Further preferably, the correction roller is externally connected to a driving motor device, and the feeding direction of the steel wire body to be processed is from right to left.

[0015] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0016] 1. The U-shaped horizontal bar in the strip groove of this scheme can be pushed out of the correction roller by an electric push rod when it is necessary to clean the correction roller. The U-shaped horizontal bar after being pushed out can use the external control terminal to drive the electric shaft. The two sponge pairs on the outside of the connected horizontal bars after flipping can contact the correction roller and become an arc state. The outer wall surface of the arc-shaped sponge pair can contact the outer wall surface of the correction roller in the rotating state, so as to clean the outer wall surface of the correction roller in time and wipe the debris on the outer wall of the attached part of the steel wire body to be processed. Manual processing is no longer required, which saves time and effort and is highly efficient, and can ensure the processing efficiency of the correction operation.

[0017] 2. At the same time, before the steel wire body to be processed enters the working chassis for processing, the steel wire body to be processed can first pass through the outer circular hole roller shaft of the damping slider, and the multiple rubber triangles in the circular hole roller shaft can fit together with the outer wall of the side vertical slide groove, so that part of the attachments on the outer wall of the steel wire body to be processed can be scraped off, reducing the probability of the attachments sticking to the correction roller, which can further ensure the use efficiency of the correction roller.
