Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, specifically a multi-angle oblique wedge tool for automobiles. Background Technology

[0002] In the automotive manufacturing industry, slant wedges are a common stamping die structure, mainly used to achieve complex angle trimming, punching, or forming processes. Traditional slant wedges typically employ a single-angle slider structure, which has limited functionality and cannot meet the demands of modern automotive parts for multi-angle, high-precision machining. For example, CN115889564A discloses a double-wedge steel pipe punch die, including an upper die fixing plate, a lower die fixing plate, an inner wedge, an outer wedge, an elastic element, an outer slider, an inner slider, and a punch. The outer and inner sliders are horizontally slidably mounted on the lower die fixing plate. The elastic element is installed between the inner and outer sliders and can elastically deform in the direction of sliding of the inner and outer sliders. A groove is formed on the side of the outer slider opposite to the inner slider. The punch is mounted on the inner slider, opposite to the groove. The upper die fixing plate is located above the lower die fixing plate. The inner and outer wedges are mounted on the upper die fixing plate. After the inner wedge moves downward and contacts the inner slider, it drives the inner slider to move closer to the outer slider. After the outer wedge moves downward and contacts the outer slider, it also drives the outer slider to move closer to the inner slider. This patent facilitates the processing of steel pipe punch structures and makes unloading easier. When the product structure is complex and the space is small, resulting in different wedge angles, existing automotive wedge tooling is difficult to form in one piece and occupies a large space. Summary of the Invention

[0003] To address the problem that existing automotive wedge tooling is difficult to integrally form and occupies a large space when the product structure is complex and the space is small, resulting in different wedge angles, this invention proposes an automotive multi-angle wedge tooling.

[0004] The technical solution adopted by this invention to solve its technical problem is: a multi-angle oblique wedge tooling for automobiles, comprising a slider: A side trimming tool block is fixedly connected to the top of slider one, slider two is movably connected to the top of slider one, a side trimming tool block two is fixedly connected to the top of slider two, a guide plate is fixedly connected to the front end of slider two, an upper mold body guide surface is fixedly connected to the end of the guide plate away from slider two, pressure plates are fixedly connected to the left and right ends of slider two respectively, and a nitrogen spring is fixedly connected to the upper side of the rear end of slider two.

[0005] Preferably, the cutting surfaces of the first and second side trimming blocks are set at different angles to achieve multi-angle trimming function.

[0006] Preferably, the connection between the guide plate and the upper mold body guide surface is provided with a wear-resistant coating to reduce friction loss.

[0007] Preferably, the pressure plate is fixed to both sides of the slider two by adjustable bolts to accommodate processing materials of different thicknesses.

[0008] Preferably, the elastic force of the nitrogen spring is adjustable to balance the dynamic load of the second slider during operation.

[0009] Preferably, the contact surfaces of slider one and slider two are provided with lubrication grooves to ensure smooth sliding.

[0010] Preferably, the first and second side trimming blades are made of high-strength alloy steel to improve durability.

[0011] Preferably, the upper mold body guide surface is designed to be inclined, which works in conjunction with the guide plate to achieve oblique feeding motion.

[0012] Preferably, the tooling further includes sensors for real-time monitoring of the displacement states of slider one and slider two.

[0013] Preferably, the bottom of the second slider is provided with a buffer pad to reduce impact vibration during operation.

[0014] The advantages of this invention are: 1. This invention utilizes the structural design of slider one and slider two. In the free state, slider two retracts to the bottom. During operation, slider two moves along the outside of slider one. When it contacts the guide surface of the upper die body, slider one continues to move normally, while slider two moves in the direction of the guide surface of the upper die body to complete the stamping at that angle. This structure can be used when the product is complex, the space is small, and the wedge angles are different. Multi-angle wedges are integrally formed, occupying little space. 2. Through the structural design of the upper die body guide surface, when the second slider contacts the inclined upper die body guide surface, while the first slider continues to move normally, the guide plate will guide the second slider to move obliquely along the inclined direction of the upper die body guide surface because the guide plate is tightly connected to the upper die body guide surface, thereby realizing the oblique feed movement of the tooling and completing the stamping processing task at a specific angle. 3. Through the structural design of the nitrogen spring, the slide block 2 will be subjected to forces of different magnitudes and directions as the slide block 2 moves and the stamping operation is carried out, generating a dynamic load. By adjusting the elastic force of the nitrogen spring, it generates a force opposite to the dynamic load, thereby balancing the forces on the slide block 2, ensuring the smoothness of the slide block 2's movement, reducing vibration and impact caused by uneven force, and improving the accuracy and quality of the stamping process.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figures 1-3 As shown, a multi-angle inclined wedge tool for automobiles includes a slider 1: The top of slider 1 is fixedly connected to a side trimming tool block 2, the top of slider 1 is movably connected to slider 2 3, the top of slider 2 3 is fixedly connected to a side trimming tool block 2 4, the front end of slider 2 3 is fixedly connected to a guide plate 5, the end of guide plate 5 away from slider 2 3 is fixedly connected to an upper mold body guide surface 6, the left and right ends of slider 2 3 are respectively fixedly connected to pressure plates 7, and the upper side of the rear end of slider 2 3 is fixedly connected to a nitrogen spring 8. During operation, slider 23 retracts to the bottom in the free state. When running, slider 23 moves along the outside of slider 1. When it contacts the upper die body guide surface 6, slider 1 continues to move normally, while slider 23 moves in the direction of the upper die body guide surface 6 to complete the stamping at that angle.

[0020] Furthermore, the cutting surfaces of side trimming block 1 2 and side trimming block 2 4 are set at different angles to achieve multi-angle trimming function; During operation, when the second slider 3 moves along the guide surface 6 of the upper die body during the stamping process, the first side trimming tool block 2 and the second side trimming tool block 4 will contact the workpiece with their respective cutting surfaces at different angles as the second slider 3 moves, thereby performing multi-angle trimming operations on the workpiece to meet the trimming requirements of complex workpieces at different angles.

[0021] Furthermore, a wear-resistant coating is provided at the connection between the guide plate 5 and the upper mold body guide surface 6 to reduce friction loss; During operation, as slider 2 3 slides along the upper mold body guide surface 6, relative friction will occur between guide plate 5 and upper mold body guide surface 6. The wear-resistant coating can reduce this friction, reduce the wear of guide plate 5 and upper mold body guide surface 6, extend the service life of the tooling, and at the same time ensure the stability of slider 2 3 sliding, avoiding the decrease in motion accuracy due to excessive wear.

[0022] Furthermore, the pressure plate 7 is fixed to both sides of the slider 2 3 by adjustable bolts to accommodate processing materials of different thicknesses; During operation, before stamping materials of different thicknesses, the position of the pressure plate 7 on both sides of the slider 2 3 can be changed by adjusting the adjustable bolts according to the actual thickness of the material. After the position of the pressure plate 7 is adjusted, it can tightly press the materials of different thicknesses to ensure that the materials will not be displaced during the stamping process and to ensure processing accuracy.

[0023] Furthermore, the elastic force of the nitrogen spring 8 is adjustable to balance the dynamic load of the slider 2 3 during operation. During operation, as the slider 2 3 moves and the stamping operation proceeds, the slider 2 3 will be subjected to forces of different magnitudes and directions, generating a dynamic load. By adjusting the elastic force of the nitrogen spring 8, it can generate a force opposite to the dynamic load, thereby balancing the forces on the slider 2 3, ensuring the smoothness of the slider 2 3's movement, reducing vibration and impact caused by uneven force, and improving the accuracy and quality of the stamping process.

[0024] Furthermore, the contact surfaces of slider 1 and slider 2 are provided with lubrication grooves to ensure smooth sliding; During operation, as slider 2 3 moves along the outer side of slider 1, lubricating oil can be added to the lubrication groove. The lubricating oil plays a lubricating role in the lubrication groove, reducing the coefficient of friction between slider 1 1 and slider 2 3, allowing slider 2 3 to slide more smoothly on slider 1 1, reducing jamming caused by excessive friction, and ensuring the stability of the tooling operation.

[0025] Furthermore, the side trimming tool block 1 2 and the side trimming tool block 2 4 are made of high-strength alloy steel to improve durability; During operation, side trimming cutter blocks 1-2 and 2-4 will frequently come into contact with the processed parts and bear great pressure and friction. High-strength alloy steel has high strength and wear resistance, which can resist these pressures and frictions, reduce the wear and damage of the cutter blocks, extend the service life of side trimming cutter blocks 1-2 and 2-4, and reduce the maintenance cost of tooling.

[0026] Furthermore, the upper mold body guide surface 6 is designed to be inclined, which works with the guide plate 5 to achieve oblique feeding motion; During operation, when slider 2 3 contacts the inclined upper die body guide surface 6, while slider 1 continues to move normally, since guide plate 5 is tightly connected to upper die body guide surface 6, guide plate 5 will guide slider 2 3 to move obliquely along the inclined direction of upper die body guide surface 6, thereby realizing the oblique feed motion of the tooling and completing the stamping processing task at a specific angle.

[0027] Furthermore, the tooling also includes sensors for real-time monitoring of the displacement status of slider 1 and slider 3; During operation, the sensors continuously collect displacement data of slider 1 and slider 2 3 and transmit this data to the control system. By analyzing the displacement data, the operator can understand the operating status of the tooling in real time, determine whether slider 1 and slider 2 3 are moving along the predetermined trajectory, and take timely measures to adjust if abnormal displacement is found, so as to ensure the accuracy and safety of stamping.

[0028] Furthermore, the bottom of slider 2 3 is equipped with a buffer pad to reduce impact vibration during operation; During operation, when the slider 2 3 is in the stamping motion or is subjected to external impact during the motion, the buffer pad can play a buffering role. It can absorb some of the impact energy, reduce the impact force transmitted by the slider 2 3 to the equipment or mold below, reduce the vibration amplitude, protect the tooling and related equipment parts, and improve the stability and reliability of the tooling operation.

[0029] Working principle: During operation, slider 1 moves normally, while slider 2 3 initially retracts to the bottom. When slider 2 3 contacts the upper mold body guide surface 6, it feeds at an angle with the cooperation of guide plate 5 and upper mold body guide surface 6. During this movement, nitrogen spring 8 balances the dynamic load of slider 2 3, ensuring smooth operation. Side trimming blocks 1 2 and 4 4, following the movement of slider 2 3, perform multi-angle trimming on the processed parts with cutting surfaces at different angles. Pressure plate 7, through adjustable bolts, clamps the processed materials of different thicknesses, ensuring that the material does not shift during processing. The lubrication grooves on the contact surfaces of Block 1 and Slider 2 ensure smooth sliding. The high-strength alloy steel material of Side Trimming Block 1 and Side Trimming Block 2 enhances durability. Sensors monitor the displacement status of Slider 1 and Slider 2 in real time, providing data feedback for the processing process and facilitating timely adjustments. The buffer pad at the bottom of Slider 2 reduces impact vibration during operation, protecting the tooling equipment. The entire tooling achieves multi-angle stamping and trimming functions through the coordinated work of its components, solving the problems of existing tooling being difficult to integrally form and occupying a large space when the product structure is complex, the space is small, and the wedge angles are different.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
