Description

Technical Field

[0001] This invention belongs to the field of cold extrusion die technology, and more specifically, relates to a cold extrusion die for automotive parts. Background Technology

[0002] The production of automotive parts uses cold extrusion dies primarily because they enable room temperature forming of high-precision, high-strength parts. This process uses high pressure to force the metal billet to flow plastically in the die, and the grain refinement improves the mechanical properties of the parts. Cold extrusion can simultaneously meet the requirements for wear resistance and dimensional stability. In addition, the process characteristics of not requiring heating reduce energy consumption and waste, meeting the automotive industry's dual requirements for environmental protection and cost.

[0003] The following problems still exist with the cold extrusion dies currently in use: 1. Although some cold extrusion dies are equipped with protective structures, these structures cannot automatically adjust their position according to the processing status, which can easily hinder workers from placing raw materials; 2. Automotive parts formed by cold extrusion tend to fall in different directions, and the discharge direction of the automotive parts after demolding cannot be controlled, which is not conducive to the collection of automotive parts after cold extrusion; 3. When the automotive parts after demolding do not fall accurately to the correct position, workers cannot clean them up in time, which can easily cause the automotive parts after demolding to get stuck in the cold extrusion die, which can easily damage the cold extrusion die. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When the control panel controls the output shafts of the two hydraulic cylinders a to extend, the mounting connecting plate drives the two extrusion forming rods to move automatically downward, realizing automatic cold extrusion forming of automotive parts; when the control panel controls the output shafts of the two hydraulic cylinders a to extend, the mounting connecting plate can drive the rectangular protective plate to move automatically downward, which plays a shielding role in the cold extrusion area and helps to reduce safety hazards; when the control panel controls the output shafts of the two hydraulic cylinders a to retract, the mounting connecting plate can drive the rectangular protective plate to move automatically upward, making it convenient for workers to place raw materials in the movable forming seat.

[0016] 2. The two circular connecting blocks of this invention enable the movable forming base to rotate under the action of the two circular connecting blocks; the two circular limiting blocks and the two arc-shaped through holes control the rotation angle of the two circular connecting blocks.

The accessory guide frame and two buffer springs of this invention serve two purposes: firstly, they guide the demolded automotive parts, facilitating their collection; secondly, they provide cushioning protection. When all the demolded automotive parts fall to the top of the accessory guide frame, the guide frame moves downwards under the weight of the two parts, causing the movable pressing block to automatically press the detection button. If one or two automotive parts do not fall accurately to the top of the guide frame, the guide frame does not move or moves only a short distance, preventing the movable pressing block from pressing the detection button. Furthermore, when the output shaft of hydraulic cylinder b retracts and the detection button is pressed, pressing the button on the control panel again will allow the control panel to extend the output shaft of hydraulic cylinder b, enabling the operator to smoothly perform the next cold extrusion operation. When the output shaft of hydraulic cylinder b retracts and the detection button is not pressed, pressing the button on the control panel again will prevent the control panel from extending the output shaft of hydraulic cylinder b, and the alarm on the control panel will activate, prompting the operator to clean up any automotive parts that have fallen outside the parts guide frame.

When the button on the control panel 700 is pressed again, the control panel 700 can control the output shaft of the hydraulic cylinder b403 to extend, allowing the operator to smoothly perform the next cold extrusion operation. When the output shaft of the hydraulic cylinder b403 retracts and the detection button 603 is not pressed, when the operator presses the button on the control panel 700 again, the control panel 700 cannot control the output shaft of the hydraulic cylinder b403 to extend, and the alarm in the control panel 700 will activate, prompting the operator to clean up any automotive parts that have fallen outside the parts guide frame 502.
