Description

Technical Field

[0001] This utility model relates to the field of metal stamping die technology, and in particular to an automatic material receiving mechanism for stamping dies. Background Technology

[0002] With the increasing market demand for automobiles, automobile companies are constantly raising their requirements for production efficiency. Stamping of automobile bodies is one of the four major processes in automobile production. The efficiency of stamping determines the efficiency of subsequent processes and even the entire automobile manufacturing process. Reducing production line downtime can greatly improve production efficiency. Among the various stamping processes, the problem of scrap jamming in trimming dies is the most common and causes significant downtime. To address this issue, a scrap hook device for stamping dies, as disclosed in CN206139751U, is proposed. This device includes a bracket, a scrap hook, and a rotating pin. The scrap hook is mounted on the bracket via the rotating pin, and the bracket is mounted on the upper die body. The scrap hook and the bracket have a rotational relationship. During the mold closing process, the scrap hook rotates upward around the rotating pin due to the obstruction of the scrap sheet. After detaching from the scrap sheet, the scrap hook returns to its original position due to gravity. When the mold returns, the upper mold retracts, and the support and scrap hook retract upward, lifting the scrap and causing it to slide down. The beneficial effects of the above-mentioned prior art are that it can effectively promote the sliding down of scrap, ensure the outflow of scrap, improve material utilization, reduce tooling and fixture costs, reduce the number of processes, and ensure that scrap slides smoothly when the trimming line shape is complex or the part shape is complex, thus ensuring the normal operation of the mold.

[0003] The aforementioned existing technical solutions have the following drawbacks: they cannot accurately record the winding distance, which leads to traction on the material strip and waste of the material strip. Utility Model Content

[0004] The purpose of this invention is to provide an automatic material receiving mechanism for stamping dies to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An automatic material take-up mechanism for stamping dies includes a winding machine and a recording device. The recording device is fixedly installed on one side of the winding machine and is used to record the length of the wound material. The recording device is connected to the control module inside the winding machine via a wired signal. The recording device includes a fixed frame, a lower roller, an upper roller, and a meter counter. The lower roller is movably mounted on the top of the fixed frame, and the upper roller is movably mounted above the upper roller via a bracket. The axes of the lower roller and the upper roller are parallel to each other. The meter counter is set on the rotating shaft of the upper roller. The surfaces of both the upper roller and the lower roller are provided with anti-slip textures.

[0006] By adopting the above technical solution, when it is necessary to rewind the material, the process of rewinding the stamped strip is carried out. The strip passes between the upper and lower rollers and is in close contact with the surfaces of the upper and lower rollers. The number of rotations of the upper roller is recorded by the meter counter, so the distance the strip moves can be known. By cooperating with the recording device and the winding machine, the winding distance and speed can be controlled.

[0007] In a further embodiment, two recording devices are provided, and the two recording devices are arranged on opposite sides of the winding machine.

[0008] In a further embodiment, both the upper and lower rollers are fitted with rubber anti-slip wheels.

[0009] By adopting the above technical solution, roller slippage can be avoided.

[0010] In a further embodiment, a first slide rod is fixedly installed at the bottom of the upper roller, and a first return spring is sleeved on the first slide rod. The top end of the first return spring is in contact with the bottom end face of the upper roller, and the bottom end of the first return spring is in contact with the top end face of the fixing plate. The upper roller has the same mounting structure as the lower roller.

[0011] By adopting the above technical solution, since the stamped strip will have a certain deformation, the upper roller and the lower roller need to be set with a certain vertical movement interval.

[0012] In a further embodiment, the winding machine is an active winding device.

[0013] In summary, this utility model has the following beneficial effects: 1. When it is necessary to rewind the material, the process of rewinding the stamped strip is carried out. The strip passes between the upper and lower rollers and is in close contact with the surfaces of the upper and lower rollers. The number of rotations of the upper roller is recorded by the meter counter, so the distance the strip has moved can be known. By cooperating with the recording device and the winding machine, the winding distance and speed can be controlled. Attached Figure Description
