Description

Technical Field

[0001] This utility model relates to the technical field of steel wire processing equipment, specifically to a steel wire straightening and cutting machine. Background Technology

[0002] In the processing of steel wire, straightening and cutting the coiled steel wire are common procedures. Generally, the steel wire is first rolled and straightened to the set length, and then cut with a cutting tool.

[0003] For example, CN 114393144 B discloses a straightening device for steel wire processing, which includes a fixed base and a feeding frame. The feeding frame is fixedly installed on the upper outer surface of the fixed base. A straightener is provided on the upper outer surface of the fixed base near the feeding frame. The straightener includes a first clamp and a second clamp, with the first clamp located on one side of the second clamp. By rotating the lifting screw, the lifting screw, in conjunction with the threaded retaining ring, can drive the positioning roller to move downward, thereby adjusting the distance between the positioning roller and the conveying roller. This allows the positioning roller and the conveying roller to accommodate steel wires of different thicknesses. The user drives a rotating rod through a motor, causing the rotating rod to drive the two sets of conveying rollers to rotate, thereby completing the conveying of the steel wire. This allows two steel wires to be simultaneously pulled out from the first and second clamps of the straightener, enabling the straightening operation of multiple steel wires to be completed simultaneously, thus improving work efficiency. However, the following problems still exist: 1. If the steel wire is thin and soft, the cut end is prone to deformation; 2. Although the device can straighten multiple steel wires at the same time, each steel wire corresponds to a set of rollers, which results in a large space occupation. Utility Model Content

[0004] The purpose of this invention is to provide a steel wire straightening and cutting machine with a reasonable structure and reliable operation that solves the above problems. On the one hand, it improves the quality of the steel wire cutting end, and on the other hand, it reduces the volume and space ratio while ensuring processing efficiency.

[0005] The technical solution of this utility model is:

[0006] A steel wire straightening and cutting machine includes a frame, a rolling straightening mechanism, and a cutting mechanism. The key technical features are: the frame consists of an upper support, a lower support, and a first lifting cylinder connected between the upper and lower supports; the rolling straightening mechanism consists of an upper roller supported inside the upper support, a lower roller supported inside the lower support, and a drive mechanism connected to the axle of the lower roller; the outer circumferential surface of the lower roller is provided with multiple lower positioning annular grooves spaced apart, and the outer circumferential surface of the upper roller is provided with upper positioning annular grooves corresponding one-to-one with the lower positioning annular grooves. The cutting mechanism includes an upper positioning plate and an upper fixed block fixed to the tail of the upper support, a lower positioning plate and a lower movable block fixed to the tail of the lower support, a second lifting cylinder fixed to the upper positioning plate, a third lifting cylinder fixed to the lower positioning plate, and a cutting blade fixed to the lower end of the cylinder rod of the second lifting cylinder. The upper fixed block has a lifting cavity corresponding to the cutting blade, and the lower surface of the upper fixed block has a cutting blade outlet. The upper end of the cylinder rod of the third lifting cylinder is connected and fixed to the lower movable block, and the upper surface of the lower movable block has an avoidance groove corresponding to the cutting blade outlet.

[0007] The above-mentioned wire straightening and cutting machine has an upper support consisting of an upper left support and an upper right support, each with a first horizontal upper edge. The lower support consists of a lower left support and a lower right support, each with a second horizontal upper edge. The first lifting cylinder consists of four cylinders connected between the first and second horizontal upper edges, arranged in pairs, front and back.

[0008] The aforementioned wire straightening and cutting machine includes a drive mechanism comprising a small gear fixed to the end of the lower roller's axle, a large gear meshing with the small gear, and a drive motor connected to the axle of the large gear.

[0009] The aforementioned wire straightening and cutting machine has a limiting plate on the front end face of the lower support, and the limiting plate has limiting holes that correspond one-to-one with the lower positioning annular groove. The inner wall of the limiting hole is provided with an anti-scratch coating.

[0010] In the above-mentioned wire straightening and cutting machine, there are multiple upper rollers and multiple lower rollers, which are arranged evenly along the length of the frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. By using the corresponding upper and lower positioning annular grooves on the upper and lower rollers to clamp multiple steel wires, the straightening operation of multiple steel wires can be completed simultaneously. Compared with the existing technology, the space ratio is reduced, thereby reducing the overall size of the machine.

[0013] 2. Multiple steel wires are clamped together by the upper fixed block and the lower movable block. Then, the second lifting cylinder is activated to drive the cutting blade downward to cut the steel wire. Due to the clamping effect of the upper fixed block and the lower movable block, the cut of the steel wire is neat and avoids deformation. Attached Figure Description
