Description

Technical Field

[0001] This invention relates to the field of wire cutting technology, specifically a wire cutting device with a buffer mechanism. Background Technology

[0002] Existing methods for straightening and cutting metal wires are mainly used for steel bars and other metal wires with larger diameters. The materials being processed have low hardness and good toughness, and the cutting length is relatively long. The cutting method uses a blade-cutting method, which results in beveled cuts. For hard and brittle metal wires, the blade-cutting method is very likely to cause cracks in the cut.

[0003] The prior art discloses a precision straightening and cutting device and method for metal wires, which involves the metal wires entering a rotating straightening cylinder through a front-end guide cylinder, being straightened, pulled, cut, and prepared for the next working cycle. Although the prior art can achieve straightening, pulling, and cutting, the prior art achieves straightening and pulling of the wires by guiding them with rollers. This makes it difficult to control the wire pulling length, and the cut surface of the prior art will have a slant. Summary of the Invention

[0004] The purpose of this invention is to provide a wire cutting device with a buffer mechanism to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire cutting device with a buffer mechanism, comprising a frame, a base plate and a base mounted on the frame, a wire straightening mechanism, a first fixing mechanism, a feeding mechanism, a second fixing mechanism and a cutting mechanism mounted on the base plate; a buffer mechanism is provided between the base and the frame, a wire straightening wheel and a roller are mounted on the top of the base, a hydraulic buffer for supporting the roller is mounted on the base, and a motor for driving the roller is mounted on the bottom of the base.

[0006] Preferably, the buffer mechanism includes an upper fixed plate, a rubber column, a lower fixed plate, a connector, and a spring. The rubber column and the spring are installed between the upper fixed plate and the lower fixed plate, and the rubber column is installed between the upper fixed plate and the lower fixed plate through the connector.

[0007] Preferably, the wire straightening mechanism includes a straightening bracket, which has a straight through hole for the wire to pass through.

[0008] Preferably, two wire straightening mechanisms are provided, with the two wire straightening mechanisms located on both sides of the first fixing mechanism.

[0009] Preferably, the cutting mechanism includes a cutting bracket, a lower cutter fixing seat is mounted on the cutting bracket, a lower cutter is mounted on the lower cutter fixing seat, and a through hole is provided on the lower cutter for the wire to pass through; a lifting cylinder is mounted on the upper part of the cutting bracket, and the lifting cylinder drives an upper cutter that cooperates with the lower cutter.

[0010] Preferably, the gap between the lower cutter and the upper cutter is 0.005 mm.

[0011] Preferably, the feeding mechanism includes a linear module, a sliding frame, and a clamping assembly. The linear module drives the sliding frame to reciprocate, and the clamping assembly is mounted on the sliding frame.

[0012] Preferably, the first fixing mechanism, the second fixing mechanism, and the clamping assembly all include a finger cylinder and a gripper, wherein the gripper is driven by the finger cylinder.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. A buffer mechanism is provided between the base and the frame. A hydraulic buffer is installed on the base to support the roller. The buffer mechanism can effectively buffer and reduce shock, thereby improving the stability of the wire conveying and facilitating subsequent straightening. The hydraulic buffer can provide buffer support for the roller.

[0015] 2. The straightening of the wire can be well achieved through the wire straightening wheel and two wire straightening mechanisms; the linear module drives the clamping assembly to move, and the straightened wire is clamped and moved by the clamping assembly, so the feeding length of the wire is easy to control.

[0016] 3. The gap between the lower and upper cutters is 0.005mm, which can solve the problem of angle when cutting wire. Attached Figure Description
