Description

Technical Field

[0001] The present invention relates to the technical field of metal material processing, and particularly relates to an alloy bar linear forging tooling and its process. Background Art

[0002] During the processing of alloy bars, it is necessary to clamp and fix the alloy bars. When clamping, in order to ensure the stability of clamping, the existing clamping tooling has too much clamping force on the alloy bars, which is likely to cause damage to the surface of the alloy bars; however, insufficient clamping force will cause the alloy bars to be unstable during processing, affecting the processing accuracy.

[0003] In addition, during the processing of alloy bars, although the clamping force of the clamping tooling on the alloy bars is not excessive, when the processing equipment has a large processing force on the alloy bars, for example, when the pressing degree is too large, there will also be micro-friction between the alloy bars and the clamping tooling under strong pressure, which will still cause damage to the surface of the alloy bars and affect the processing accuracy of the alloy bars.

[0004] In summary, how to accurately control the clamping force of alloy bars, further reduce the damage to alloy bars, and at the same time ensure the processing accuracy of alloy bars has become a problem to be solved. Summary of the Invention

Among them, a spring member is installed between the horizontal pressing rod and the horizontal pressure sensing module, and an extrusion disk for extrusion contact with the horizontal pressure sensing module is configured at the side end of the spring member.

[0015] An alloy bar linear forging process includes the following contents:

[0016] S1. Initial debugging:

[0017] S1.1. Select a suitable clamping piece according to the specifications of the alloy bar and install it at the position of the clamping movable guide piece.

[0018] S1.2. Manually support the alloy bar and place the alloy bar between the two clamping pieces.

[0019] S1.3. Then, start the horizontal electromagnetic module to generate a repulsive force to push the horizontal permanent magnet outward, and use the clamping piece to firmly clamp the alloy bar.

[0020] S1.4. Adjust the height of the support base until the support pressure sensing module detects that the pressure parameter becomes P x0 , where P x0 is the pressure parameter generated by the alloy bar on the support pressure sensing module when the alloy bar is not clamped by the clamping piece and is independently placed on the upper side of the support contact block.

[0021] S1.5. At this time, the pressure parameter detected by the vertical pressure sensing module is recorded as P y0 .

[0022] S1.6. At this time, the pressure parameter detected by the horizontal pressure sensing module is recorded as P z0 .

[0025] S3.1. When P xs >P x0 , the first pressure difference ΔP1 = P xs - P y0 , then the vertical electromagnetic module adjusts the magnetic attraction intensity on the vertical permanent magnet to make the pressure parameter detected by the vertical pressure sensing module reach P y0 + ΔP1.

[0026] S3.2. When P xs <P x0 , the first pressure difference ΔP1 = P y0 - P xs , then the vertical electromagnetic module adjusts the magnetic attraction intensity on the vertical permanent magnet to make the pressure parameter detected by the vertical pressure sensing module reach P y0 - ΔP1.

[0027] S4. During the process of the forging equipment processing the alloy bar, assume that the pressure parameter detected by the horizontal pressure sensing module in real time is Pzs 。

[0028] S4.1. When P zs >P z0 , the horizontal electromagnetic module reduces the repulsive force on the horizontal permanent magnet until P zs =P z0 。

[0029] S4.2. When P zs <P z0 , the horizontal electromagnetic module increases the repulsive force on the horizontal permanent magnet until P zs =P z0 。

[0030] S5. After the forging equipment finishes processing the alloy bar, the vertical electromagnetic module and the horizontal electromagnetic module are powered off, and the clamping member separates from the alloy bar under the reverse acting force of the spring member, and the processed alloy bar is taken out.

[0031] Compared with the existing technology, the beneficial effects of the present invention are:

[0032] Through the synergistic effect of the support pressure sensing module, the vertical pressure sensing module and the horizontal pressure sensing module, the present invention realizes the precise monitoring and adjustment of the clamping force; during the processing, it can dynamically adjust the vertical electromagnetic module and the horizontal electromagnetic module according to the force condition of the alloy bar to ensure that the clamping force is just right, and at the same time the clamping member can be synchronously matched with the downward movement micro-state of the alloy bar in the vertical direction, which not only avoids damaging the surface of the alloy bar due to excessive clamping, but also prevents the alloy bar from undergoing micro-dynamic friction due to insufficient clamping, further reducing the damage to the alloy bar and ensuring the processing accuracy of the alloy bar.

Specific embodiments

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

[0041] Embodiment 1. The present invention designs a linear forging tooling for alloy bars, and the specific structural content is as follows:

[0042] (I) Overall layout

[0043] As Figure 1 , the linear forging tooling for alloy bars is mainly constructed on the fixed base 1. The height of its key component, the supporting base body 10, can be flexibly adjusted by cooperating with the bracket screw 17 and the nut 18 on the fixed base 1. The supporting base body 10 is provided with a vertical installation through groove adapted to the bracket screw 17, and the nut 18 is fastened on the upper and lower sides to ensure the stability and variable height of the supporting base body 10, laying a foundation for subsequent operations. Above the supporting base body 10, a supporting contact block 12 is installed, and its surface is provided with specific anti-slip textures (depth 0.1 - 0.5 mm, such as equidistant diamond or wavy, and the material hardness is lower than that of the alloy bar 19) to stably support the alloy bar 19 and avoid scratching the surface of the bar. The supporting base body 10 is also equipped with a supporting pressure sensing module 11 to accurately monitor the downward pressure of the supporting contact block 12 and provide key data for process control.

[0044] As Figure 1 , Figure 2, on the fixed base 1, the first guiding component 2, the second guiding component 4 and the clamping guiding component 3 are orderly installed on both sides of the supporting base body 10. The first guiding component 2 and the second guiding component 4 are inserted and matched with each other, and the clamping guiding component 3 is fixed above the second guiding component 4. This structural design ensures the stability and accuracy of the coordinated work of each component.

[0045] (2) The first guiding component

[0046] As Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , the core component of the first guiding component 2 is the first fixing frame 201. The first vertical slot 202 with an upward opening is internally provided 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 and matched with the vertical permanent magnet 403 in the second guiding component 4, and a gap is reserved between the two, which not only ensures the heat dissipation requirement of the vertical electromagnetic module 203, but also can adapt to the slight deformation of the bar homogeneous plate 402 when it is squeezed, ensuring the stable overall performance of the tooling.

[0047] (3) The second guiding component

[0048] As Figure 3 , Figure 5 , Figure 6 , the second guiding component 4 includes a second guide block 401 inserted into the first vertical slot 202, and a vertical permanent magnet 403 and a bar homogeneous plate 402 are installed on its bottom side. The bar homogeneous plate 402 has the same material as the alloy bar 19 (refer to Figure 1 ), and the bottom side surface of the bar homogeneous plate 402 is lower than the bottom side surface of the vertical permanent magnet 403, ensuring that the pressure can be effectively transmitted during the processing without affecting the functions of other components.

[0049] (4) The clamping guiding component

[0050] As Figure 2 , Figure 3 , Figure 4, the clamping guide assembly 3 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 (which is embedded with a horizontal permanent magnet 601 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.

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 5 The 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.

[0052] Embodiment 2: The present invention designs a linear forging process for alloy bars, the specific contents of which are as follows:

[0053] 1. Initial debugging

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Support height adjustment: Carefully adjust the support base 10 height, when the pressure parameter reaches P x0 (P x0When the pressure generated by the alloy bar 19 alone on the support pressure sensing module 11 without being clamped reaches a certain value (the specific value is not given in the text), stop the adjustment. At this time, the alloy bar 19 is in a natural support state, establishing a benchmark for subsequent precise pressure control.

[0058] Pressure parameter recording: In the above state, record the pressure parameter P detected by the vertical pressure sensing module 204 y0 and the pressure parameter P detected by the horizontal pressure sensing module 16 z0 . These parameters will serve as important reference bases for pressure adjustment during subsequent processing.

[0059] (II) Processing process

[0060] Support pressure monitoring and vertical position adjustment: During the forging process, the support pressure sensing module 11 continuously monitors the pressure parameter P xs .

[0061] When P xs >P x0 , calculate the first pressure difference ΔP1 = P xs - P y0 . Based on this, the vertical electromagnetic module 203 increases the magnetic attraction intensity on the vertical permanent magnet 403, so that the pressure parameter detected by the vertical pressure sensing module 204 reaches P y0 +ΔP1, ensuring that the alloy bar 19 is evenly stressed in the vertical direction and avoiding excessive friction or extrusion damage between the bar and the tooling due to changes in the support pressure. Conversely, when P xs <P x0 , calculate ΔP1 = P y0 - P xs . The vertical electromagnetic module 203 reduces the magnetic attraction intensity, making the pressure parameter detected by the vertical pressure sensing module 204 reach P y0 - ΔP1, maintaining the stable support state of the bar.

[0062] Horizontal pressure monitoring and adjustment: The horizontal pressure sensing module 16 continuously monitors the pressure parameter P 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 loosen the clamping of the alloy bar 19 until P zs = P z0 , preventing excessive lateral clamping force from damaging the bar. If P zs <P z0 , then increase the repulsive force to make P zs = P z0 , ensuring that the alloy bar 19 always maintains a stable position during processing, without deviation or loosening, and ensuring processing accuracy.

[0063] (III) Processing completion

[0064] After the forging equipment finishes processing the alloy bar 19, cut off the power supply of the vertical electromagnetic module 203 and the horizontal electromagnetic module 5. At this time, the clamping member 9 separates from the alloy bar 19 under the reverse acting 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, precise control of the clamping force on the alloy bar is achieved, effectively reducing the damage to the alloy bar during the processing and ensuring high processing accuracy.

[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
