DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] Embodiment 1: The present invention designs a linear forging tool for alloy bars, and the specific structure is as follows: 1. Overall layout like Figure 1 The linear forging tooling for alloy bars is mainly constructed on a fixed base 1. The height of the key component, the support base 10, can be flexibly adjusted by cooperating with the support screw 17 and the nut 18 on the fixed base 1. The support base 10 is provided with a vertical installation through slot adapted to the support screw 17, and the nut 18 is fastened on the upper and lower sides to ensure that the support base 10 is stable and highly variable, laying the foundation for subsequent operations. Above the support base 10, a support contact block 12 is installed, and its surface is provided with a specific anti-slip texture (depth 0.1-0.5 mm, such as equidistant rhombus or wavy shape, and the material hardness is lower than that of the alloy bar 19), which is used to stably support the alloy bar 19 and avoid scratching the surface of the bar. The support base 10 is also equipped with a support pressure sensing module 11 to accurately monitor the downward pressure of the support contact block 12 and provide key data for process control.

[0038] like Figure 1 , Figure 2 On the fixed base 1, the first guide assembly 2, the second guide assembly 4 and the clamping guide assembly 3 are orderly installed on both sides of the support base 10. The first guide assembly 2 is plug-in matched with the second guide assembly 4, and the clamping guide assembly 3 is fixed on the second guide assembly 4. This structural design ensures the stability and accuracy of the coordinated work of each component.

[0039] (II) First guide component like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 The core component of the first guide assembly 2 is the first fixed frame 201, and the first vertical slot 202 opened upward is embedded with a vertical electromagnetic module 203 and a vertical pressure sensing module 204. The vertical pressure sensing modules 204 on both sides of the vertical electromagnetic module 203 can accurately sense the pressure change, which plays a key role in adjusting the clamping force in the subsequent process. The vertical electromagnetic module 203 is aligned with the vertical permanent magnet 403 in the second guide assembly 4, and a gap is reserved between the two, which not only guarantees the heat dissipation requirements of the vertical electromagnetic module 203, but also can adapt to the slight deformation of the rod homogeneous plate 402 when it is squeezed, ensuring the overall stability of the tooling performance.

[0040] (III) Second guide component like Figure 3 , Figure 5 , Figure 6 The second guide assembly 4 includes a second guide block 401 inserted into the first vertical slot 202, and a vertical permanent magnet 403 and a rod homogeneous plate 402 are installed on the bottom side of the second guide block 401. The rod homogeneous plate 402 and the alloy rod 19 (reference Figure 1 ) is made of the same material, and its bottom side is lower than the bottom side of the vertical permanent magnet 403, ensuring that the pressure can be effectively transmitted during the processing without affecting the functions of other components.

[0041] like Figure 2 , Figure 3 , Figure 4 , the second guide assembly 4 is internally provided with a first movable cavity 301, a second movable cavity 302 and a third movable cavity 303 which are interconnected. The horizontal electromagnetic module 5 is embedded in the first movable cavity 301, and drives the horizontal guide 6 (a horizontal permanent magnet 601 is embedded on the side facing the horizontal electromagnetic module 5) to move in the cavity. The transverse disk 7 moves flexibly in the second movable cavity 302, the clamped movable guide 8 is precisely guided by the guide groove structure, and the transverse pressure rod 13 is inserted into the third movable cavity 303. These components move in coordination to achieve effective clamping and pressure regulation of the alloy bar 19. At the same time, a horizontal pressure sensing module 16 is configured to detect the moving pressure of the transverse pressure rod 13 through the spring member 14 and the extrusion disk 15, providing a basis for pressure feedback and adjustment in the process.

[0042] (IV) Clamping guide assembly like Figure 1 , Figure 2 , Figure 3 , Figure 5The clamping guide assembly 3 and the second guide assembly 4 cooperate closely to provide a stable guide for the clamping movable guide 8, ensuring that the clamping member 9 installed at the side end of the clamping movable guide 8 can accurately apply a clamping force to the alloy bar 19. The surface of the clamping member 9 facing the alloy bar 19 is provided with an anti-slip texture, which works together with the anti-slip texture on the supporting contact block 12 to enhance the clamping stability of the alloy bar 19, prevent the displacement of the bar during processing, and ensure processing accuracy.

[0043] Embodiment 2: The present invention designs a linear forging process for alloy bars, the specific contents of which are as follows: 1. Initial debugging Clamping piece adaptation: According to the specifications of the alloy bar 19, select a suitable model from a variety of clamping pieces 9 and firmly install them in the position of the clamping movable guide 8. Different specifications of alloy bars have different sizes and material properties. The adapted clamping piece 9 can ensure effective clamping and avoid excessive extrusion and damage to the bar.

[0044] Bar placement: The operator manually supports the alloy bar 19 and carefully places it between the two clamps 9, ensuring that the bar is roughly centered in preparation for subsequent precise clamping.

[0045] Initial clamping: Start the horizontal electromagnetic module 5, the repulsive force generated by it acts on the horizontal permanent magnet 601, pushing the horizontal guide 6, the horizontal shift plate 7 and the clamping movable guide 8 to move, so that the clamping member 9 fits tightly against the alloy rod 19, achieving initial stable clamping.

[0046] Support height adjustment: Carefully adjust the support base 10 height, when the pressure parameter reaches P x0 (P x0 When the pressure is 0 (the pressure generated by the supporting pressure sensing module 11 alone when the alloy rod 19 is not clamped), the adjustment is stopped. At this time, the alloy rod 19 is in a natural supporting state, which establishes a benchmark for subsequent precise pressure control.

[0047] Pressure parameter recording: In the above state, the pressure parameters P detected by the vertical pressure sensing module 204 are recorded respectively. y0 and the pressure parameter P detected by the horizontal pressure sensing module 16 z0 , these parameters will serve as an important reference for pressure adjustment in subsequent processing.

[0048] (II) Processing Support pressure monitoring and vertical position adjustment: During the forging process, the support pressure sensor module 11 monitors the pressure parameter P in real time. xs .

[0049] When P xs >P x0 When the first pressure difference ΔP1=P xs -Py0 The vertical electromagnetic module 203 accordingly enhances the magnetic attraction strength of the vertical permanent magnet 403, so that the pressure parameter detected by the vertical pressure sensor module 204 reaches P y0 +ΔP1, ensure that the alloy bar 19 is balanced in the vertical direction, and avoid excessive friction or extrusion damage between the bar and the tooling due to changes in support pressure. xs <P x0 When ΔP1=P y0 -P xs , the vertical electromagnetic module 203 reduces the magnetic attraction strength, so that the pressure parameter detected by the vertical pressure sensor module 204 reaches P y0 -ΔP1, maintain the stable support state of the bar.

[0050] Horizontal pressure monitoring and adjustment: The horizontal pressure sensor module 16 monitors the pressure parameter P in real time zs If P zs >P z0 , the horizontal electromagnetic module 5 reduces the repulsive force on the horizontal permanent magnet 601, driving the clamping member 9 to moderately relax the clamping of the alloy bar 19 until P zs =P z0 , to prevent the lateral clamping force from being too large and damaging the bar. zs <P z0 , the repulsive force is enhanced, so that P zs =P z0 , ensuring that the alloy bar 19 always maintains a stable position during the processing, does not deviate or loosen, and ensures processing accuracy.

[0051] (III) Processing completed After the forging equipment completes the processing of the alloy bar 19, the power supply of the vertical electromagnetic module 203 and the horizontal electromagnetic module 5 is cut off. At this time, the clamping member 9 is separated from the alloy bar 19 under the reverse force of the spring member 14, and the operator can safely and conveniently take out the processed alloy bar 19 to complete the entire forging process. Through the close cooperation of the above-mentioned tooling structure and process steps, the precise control of the clamping force of the alloy bar is achieved, which effectively reduces the damage to the alloy bar during the processing process and ensures a high processing accuracy.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
