Description

Technical Field

[0001] This utility model relates to the field of structural component stamping technology, specifically a stamping device for the production of automotive structural components. Background Technology

[0002] The production process of automotive structural components includes the stamping process for automotive tubular parts.

[0003] In the current tube stamping process, workers manually place the cylindrical tube end into the stamping area before starting the stamping machine, causing the upper and lower dies to merge and create a pressing effect on the tube end. However, since automotive tube ends often have holes that need to connect in subsequent assembly processes, the holes and the lower die must be perpendicular to prevent misalignment during stamping. Currently, the perpendicularity of the holes is mostly determined by worker observation, which can lead to errors over time, resulting in lower yield and low stamping efficiency.

[0004] Therefore, this utility model proposes a stamping device for the production of automotive structural parts. Utility Model Content

[0005] The purpose of this utility model is to provide a stamping device for the production of automotive structural parts, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a stamping device for the production of automotive structural parts, including a base, a lower die above the base, an arc-shaped support above the lower die, a laser instrument inside the base, a control box at the bottom of the laser instrument and electrically connected thereto, and a correction unit above the base for driving the rotation of the tube, through which the slot of the rotating tube is perpendicular to the base.

[0006] Preferably, the calibration unit includes a connecting block located inside the pipe, a connecting shaft at the end of the connecting block, a motor at the end of the connecting shaft, the motor being electrically connected to the control box, a frame on the outer wall of the motor, and a connecting plate at the bottom of the frame.

[0007] Preferably, the outer wall of the connecting block abuts against the inner wall of the pipe fitting, and the laser emitted by the laser device has not completely passed through the hole and groove of the pipe fitting, the control box starts the motor to drive the connecting block to rotate.

[0008] Preferably, a fixing sleeve is provided above the connecting plate, and a fixing cylinder is provided inside the fixing sleeve. The end of the fixing cylinder contacts the end of the pipe fitting. A connecting ring is provided at the other end of the fixing cylinder, and a push rod is provided on the side of the connecting ring. The push rod is electrically connected to the control box.

[0009] Preferably, there is a repulsive force between the side of the connecting ring and the side of the fixing sleeve, and the fixing cylinder slides freely within the fixing sleeve.

[0010] Preferably, the overall shape of the connecting block is conical.

[0011] This utility model has at least the following beneficial effects:

[0012] In this invention, after the pipe fitting is placed on the arc-shaped support and inserted into the fixing sleeve, if the laser beam does not completely pass through the slot but remains on the outer wall of the pipe fitting, it indicates that the slot of the pipe fitting is not perpendicular to the base and is in an incorrect stamping state. At this time, the control box will drive the motor to rotate, causing it to rotate the connecting block and the pipe fitting until the laser beam can completely pass through the slot. At this point, the end of the pipe fitting is in the optimal stamping state, and the motor will automatically stop rotating, thus proceeding to the next stamping process. Compared with the prior art, there is no need for manual rotation and alignment of the pipe fitting, making the alignment work intelligent and automated, improving the stamping yield and stamping efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a stamping device for producing automotive structural parts, including a base 1, a lower die 2 fixedly connected to the base 1, an arc-shaped bracket 3 fixedly connected to the lower die 2, a laser instrument 4 inside the base 1, a control box 5 electrically connected to the bottom of the laser instrument 4, the laser emitted by the laser instrument 4 is vertically upward, and a correction unit for driving the rotation of the tube is provided above the base 1. Through the correction unit, the hole groove of the rotating tube is perpendicular to the base 1, reducing the error generated during stamping and improving the stamping yield.

[0019] The calibration unit includes a connecting block 6 located inside the pipe fitting. The connecting block 6 has a tapered shape, which makes it easier for workers to fit the end of the pipe fitting onto the outer wall of the connecting block 6. The end of the connecting block 6 is equipped with a connecting shaft 7 and is fixedly connected to it. The end of the connecting shaft 7 is equipped with a motor 8. The connecting shaft 7 is connected to the rotating shaft of the motor 8 via a coupling. The motor 8 is electrically connected to the control box 5. The outer wall of the motor 8 is equipped with a frame 9 and is fixedly connected to it. The bottom of the frame 9 is equipped with a connecting plate 10 and is fixedly connected to it. The connecting plate 10 is located above the base 1 and is fixedly connected to it. The outer wall of the connecting block 6 abuts against the inner wall of the pipe fitting. When the motor 8 is rotating, the connecting block 6 can drive the pipe fitting to rotate. When the laser emitted by the laser instrument 4 has not completely passed through the hole groove of the pipe fitting, the control box 5 starts the motor 8 to drive the connecting block 6 to rotate, thereby driving the pipe fitting to rotate slightly.

[0020] Furthermore, a fixing sleeve 11 is provided above the connecting plate 10 and is fixedly connected thereto. A fixing cylinder 12 is provided inside the fixing sleeve 11. The end of the fixing cylinder 12 contacts the end of the pipe fitting. A connecting ring 13 is provided at the other end of the fixing cylinder 12 and is rotatably connected thereto. A push rod 14 is provided on the side of the connecting ring 13 and is fixedly connected thereto. The push rod 14 is located inside the frame 9 and is fixedly connected thereto. The push rod 14 is electrically connected to the control box 5. There is a repulsive force between the side of the connecting ring 13 and the side of the fixing sleeve 11. This repulsive force can keep the fixing cylinder 12 in the initial position and allow the fixing cylinder 12 to slide freely inside the fixing sleeve 11.

[0021] Working principle:

[0022] When the worker places the pipe fitting on the arc-shaped bracket 3 and inserts it into the fixing sleeve 11, the connecting block 6 is also located inside the pipe fitting. At this time, the laser device 4 located inside the base 1 will emit a laser beam to the pipe fitting. If the laser does not completely pass through the slot but remains on the outer wall of the pipe fitting, it indicates that the slot of the pipe fitting is not perpendicular to the base 1 and is in an incorrect stamping state. At this time, the control box 5 will drive the motor 8 to rotate, causing it to drive the connecting block 6 and the pipe fitting to rotate until the laser beam can completely pass through the slot. At this time, the end of the pipe fitting is in the optimal stamping state, and the motor 8 will automatically stop rotating. Then, the upper die will be used to squeeze the lower die 2 to complete the stamping process. Compared with the existing technology, there is no need for manual rotation and alignment of the pipe fitting, making the alignment work intelligent and automated, improving the stamping yield and stamping efficiency.

[0023] Furthermore, after stamping a single pipe fitting, the control box 5 drives the push rod 14 to push the connecting ring 13, causing the connecting ring 13 and the fixed cylinder 12 to push the pipe fitting inside the fixed sleeve 11, ultimately causing the pipe fitting to exit from the fixed sleeve 11 and lose contact with the connecting block 6. At this point, the operator can directly lift the stamped pipe fitting upwards. After lifting, the repulsive force between the connecting ring 13 and the fixed sleeve 11 will drive the connecting ring 13 and the fixed cylinder 12 to reset, facilitating the stamping of the next pipe fitting. This method improves the material change speed between multiple pipe fittings and further accelerates the efficiency of continuous stamping operations.
