Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to a hot forging clamping and conveying device. Background Art

[0002] Forgings can be divided into cold forging, warm forging and hot forging according to the temperature of the blank during processing. Cold forging is forging at room temperature or slightly above room temperature, warm forging is forging at a temperature above room temperature but below the recrystallization temperature of the material, and hot forging is forging at a high temperature above the recrystallization temperature of the material. Forging can eliminate the porosity and holes in the metal and improve the mechanical properties of the forging. After hot forging, the forging needs to be moved to the forging table by a clamping and feeding device, and the clamping and feeding device is made of high-temperature resistant metal materials.

[0003] The patent document with authorization announcement number CN115783629B discloses an automatic conveying device for forgings, including a frame, a turning mechanism and a conveying mechanism; the turning mechanism includes a turning frame, a wheel frame, and a turning drive mechanism; the turning drive mechanism includes a turning drive motor, a transverse slide rail, and a transverse driving mechanism; a clamping mechanism is provided between the wheel frame and the turning frame; the conveying mechanism includes a chain, a sprocket and a conveying rod; when the device is in use, the driving wheels on both sides of the metal bar are driven to move toward the middle through the clamping mechanism to clamp the metal bar, and the position of the turning frame is adjusted through the turning mechanism to release the driving wheel, so that the metal bar falls on the conveying mechanism, so that the heating end of the metal bar is in a suspended state to avoid contact with the conveying mechanism, and then the metal bar is conveyed to the next processing station through the conveying mechanism.

[0004] However, the above-mentioned conveying device is only suitable for clamping and conveying metal bars that are locally heated at one end. By avoiding contact between the heated end and the clamping mechanism or the conveying mechanism, temperature loss or oxide scale adhesion can be prevented. However, the effect is not ideal for metal bars that are heated as a whole. The contact between the bar and the clamping mechanism or the conveying mechanism may affect the uniformity of the bar temperature. In addition, the above-mentioned conveying device is only suitable for clamping cylindrical metal bars. It is difficult to clamp bars with irregular cross-sections, which affects the clamping stability. Summary of the invention

[0033] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0034] like Figures 1 to 9 As shown, a hot forging clamping and conveying device of the present invention comprises a conveying assembly for conveying the forging 1 and a clamping mechanism for clamping the forging 1, wherein the clamping mechanism is arranged on the conveying assembly.

[0035] The clamping mechanism is provided with at least two groups, and multiple groups of clamping mechanisms are provided in a linear array. In the present embodiment, two groups of clamping mechanisms are taken as an example for description, and each group of clamping mechanisms includes a clamping assembly, a heat insulation assembly and an adjustment assembly. The clamping assembly includes two inner arc plates 21 and a driving member 23. The two inner arc plates 21 are symmetrically arranged and one end of them is abutted. The driving member 23 is used to drive the two inner arc plates 21 to move synchronously in the opposite direction so that the other ends of the two inner arc plates 21 can be closed. At this time, the two inner arc plates 21 form a closed circular ring. The heat insulation assembly includes an insulation belt 31 and a winding structure. When the inner arc plate 21 is closed, the insulation belt 31 is in the inner arc The inner arc plate 21 is between the plate 21 and the forging 1, and is wrapped around the outside of the forging 1. The winding structure is used to keep the insulation belt 31 in a tensioned state. The adjustment component includes a plurality of telescopic rods 41 and a self-locking structure. The plurality of telescopic rods 41 are arranged at intervals along the circumference of the inner arc plate 21. Each telescopic rod 41 is arranged along the radial direction of the inner arc plate 21. One end of the telescopic rod 41 is connected to the inner arc plate 21, and the other end is abutted against the insulation belt 31. An elastic member 1 is provided in the telescopic rod 41 to push the insulation belt 31 to adapt to the shape of the forging 1 during the closing process. The elastic member 1 can be set as a spring. The self-locking structure is used to lock the length of the telescopic rod 41 after the closing is completed.

[0036] After the hot forging is completed, the forging 1 is taken out from the heating device, and then the forging 1 is clamped by the clamping mechanism, and then the clamped forging 1 is transported by the conveying assembly, wherein the conveying assembly can be a conveyor belt or a conveying trolley and other existing technologies, which will not be described in detail here, and only the clamping mechanism is described in detail, specifically, as follows Figures 1 to 8 As shown, when the forging 1 is clamped, the two inner arc plates 21 are driven to rotate in opposite directions to close through the driving member 1 23, and the insulating belt 31 and the telescopic rod 41 arranged on the inner arc plate 21 are driven to rotate synchronously. When the insulating belt 31 contacts the peripheral side of the forging 1, the telescopic rod 41 will adapt the length according to the distance between the inner arc plate 21 and the peripheral side of the forging 1, and under the action of the elastic member 1, the insulating belt 31 is pushed to adapt to the shape of the forging 1, so that when the closing is completed, the insulating belt 31 is tightly wrapped around the outside of the forging 1, and each telescopic rod 41 can be used to close the forging 1. A radial clamping force is provided to clamp the forging 1 in the middle of the inner arc plate 21. At this time, the length of the telescopic rod 41 is locked by the self-locking structure to ensure the stability of the clamping of the forging 1 and avoid the forging 1 shaking back and forth on the inner side of the inner arc plate 21 during transportation to affect the clamping effect. In addition, an insulating belt 31 is arranged between the clamping assembly and the forging 1 to slow down the transfer of heat from the forging 1 to the clamping mechanism and reduce the rapid cooling caused by contact. At the same time, the forging 1 can be buffered to a certain extent to avoid damage to the surface of the forging 1 caused by the clamping mechanism during the clamping process.

[0037] In some embodiments, the clamping assembly also includes two outer arc plates 22, and the two outer arc plates 22 are correspondingly arranged on the convex sides of the two inner arc plates 21 and are coaxially arranged with the inner arc plates 21. The end of the telescopic rod 41 away from the insulation belt 31 passes through the inner arc plate 21 and abuts against the inner arc surface of the outer arc plate 22. A push block 42 is provided at the end of the telescopic rod 41 facing the insulation belt 31. One side of the push block 42 is hinged to the end of the telescopic rod 41, and the other side can contact the surface of the insulation belt 31.

[0038] Specifically, Figures 2 to 8 As shown, in the initial state, the outer arc plate 22 and the inner arc plate 21 in the clamping mechanism are both in an unclosed state. At this time, each telescopic rod 41 is extended to the longest length under the action of the internal elastic member 1, and the thermal insulation belt 31 is kept in a tensioned state under the action of the winding structure. In the process of the inner arc plate 21 in the clamping mechanism closing inward to clamp the forging 1, when the surface of the thermal insulation belt 31 contacts the push block 42 provided on the telescopic rod 41, the push block 42 stops moving. At this time, as the inner arc plate 21 continues to close, the telescopic rod 41 will shrink and compress the elastic member 1 to store force until the inner arc plate 21 is completely closed. In this process, each telescopic rod 41 can adapt its length according to the distance between the inner arc plate 21 and the peripheral side of the forging 1 to ensure the clamping effect of the forging 1.

[0039] In some embodiments, a mounting plate 11 is provided on the conveying assembly, and the clamping mechanism is installed on the conveying assembly through the mounting plate 11. A support seat 12 is provided on the mounting plate 11. The end of the support seat 12 is hinged to the outer arc surface of the outer arc plate 22 through a hinge shaft. A slide rod 221 is connected to the outer arc surface of the outer arc plate 22. A slide groove 1 is provided on the slide rod 221 along its length direction. A slider is slidably provided in the slide groove 1. A driving member 23 is provided on the support seat 12. The output end of the driving member 23 extends vertically and is hinged to the slider. A fixing block 24 is provided on the inner arc surface of the outer arc plate 22. A rod member 211 is connected to the outer arc surface of the inner arc plate 21. A horizontal slide groove 241 is provided on the fixing block 24. The horizontal slide groove 241 is arranged along the axial direction of the outer arc plate 22. The rod member 211 extends into the horizontal slide groove 241 and slides with the horizontal slide groove 241.

[0040] Specifically, Figures 2 to 5 , Figure 8As shown, start the driving member 23 so that its output end extends vertically, which can drive the slider hinged to the output end to move up and down, and through the sliding cooperation between the slider and the slide bar 221, drive the slide bar 221 to flip, thereby driving the outer arc plate 22 connected to the slide bar 221 to rotate around the hinge axis relative to the support seat 12, so that the two outer arc plates 22 in the same clamping mechanism rotate synchronously in opposite directions to close. Since the outer arc plate 22 and the inner arc plate 21 slide relative to each other in the axial direction and are relatively fixed in the radial direction, the outer arc plate 22 can drive the inner arc plate 21 to rotate while rotating, so that the other ends of the two inner arc plates 21 are closed. At this time, the two inner arc plates 21 form a complete ring, and with the cooperation of the insulation component and the adjustment component, the forging 1 is clamped.

[0041] In some embodiments, the insulation belt 31 is asbestos cloth, which is a material with high fire resistance, electrical insulation and thermal insulation. It is made of asbestos fibers interwoven. These properties make it very suitable for insulation and heat preservation applications. Asbestos cloth can withstand high temperatures, with a softening point close to 1700°C. It can be used for a long time in an environment of 1200°C. It can slow down the transfer of heat from the forging 1 to the clamping mechanism, reduce rapid cooling due to contact, avoid thermal stress and potential crack risks caused by local excessive cooling, and ensure the quality of the forging 1.

[0042] In some embodiments, the winding structure includes two winding rollers 32, and one end where the two inner arc plates 21 abut against each other is defined as the abutting end, and the other end is defined as the closed end. The two winding rollers 32 are rotatably connected to the abutting ends of the two inner arc plates 21 through a torsion spring, respectively. There are two insulation belts 31, which are respectively arranged corresponding to the two inner arc plates 21. One end of each insulation belt 31 is fixedly connected to the abutting end of the inner arc plate 21, and the other end bypasses the closed end of the inner arc plate 21 and is wound on the winding roller 32.

[0043] Specifically, Figures 2 to 6 As shown, in the initial state, the outer arc plate 22 and the inner arc plate 21 in the clamping mechanism are both in an unclosed state, at which time the thermal insulation belt 31 is maintained in a tensioned state of minimum length. During the process of closing and clamping the two inner arc plates 21, the thermal insulation belt 31 can be adapted in length according to the shape of the circumference of the forging 1, driving the winding roller 32 to rotate for material discharge, and causing the torsion spring 1 to twist for force accumulation until the forging 1 is clamped. At this time, the thermal insulation belt 31 is tightly wrapped around the circumference of the forging 1. After the forging 1 is removed from the clamping mechanism, the winding roller 32 rotates in the opposite direction under the action of the torsion spring 1 to rewind the material, and the excess thermal insulation belt 31 is rewound on the outside of the winding roller 32, so that the thermal insulation belt 31 is again in a tensioned state of minimum length.

[0044] In some embodiments, the self-locking structure includes a fixing member 43, a locking rod 44 and a second driving member. The fixing member 43 is fixedly arranged inside the inner arc plate 21. The middle part of the locking rod 44 is rotatably connected to the fixing member 43 through a second torsion spring. Each telescopic rod 41 is provided with a plurality of protrusions 411 along its length direction. One end of the locking rod 44 is provided with a locking block 441 matched with the protrusion 411, and the other end of the locking rod 44 is provided with a friction block 442 that is in friction contact with the surface of the insulation belt 31. The second driving member is used to drive the friction block 442 to move to release the friction contact between the friction block 442 and the insulation belt 31.

[0045] Specifically, Figures 1 to 8 As shown, in the initial state, the thermal insulation belt 31 is maintained in a tensioned state of minimum length. In the process of clamping the forging 1 by closing the two inner arc plates 21, the thermal insulation belt 31 can be adapted according to the shape of the surface of the forging 1, driving the winding roller 32 to rotate for unloading. When the thermal insulation belt 31 moves, the friction contact between the thermal insulation belt 31 and the friction block 442 can drive the friction block 442 to move with the thermal insulation belt 31, so that the locking rod 44 rotates around the hinge point between the locking rod 44 and the fixing member 43, and the torsion spring 2 is twisted to store force. When the locking rod 44 rotates, the locking block 441 moves, so that the locking block 441 is disengaged from the protrusion 411, and the locking of the protrusion 411 is released, that is, the telescopic The rod 41 is in an unlocked state and can shrink according to the shape of the forging 1, and push the insulation belt 31 to adapt to the shape of the forging 1, so as to stably clamp the forgings 1 of different shapes; after completing the clamping of the forging 1, the friction block 442 is driven to move by the second driving member to release the friction contact between the friction block 442 and the insulation belt 31. At this time, the locking rod 44 will rotate in the opposite direction to reset under the action of the second torsion spring, and make the locking block 441 move in the opposite direction to re-match with the protrusion 411 to lock the protrusion 411. That is, the telescopic rod 41 is in a locked state at this time and the length cannot be adjusted, so that the forging 1 can be stably clamped to prevent the forging 1 from shaking on the inner side of the inner arc plate 21 during transportation.

[0046] In some embodiments, driving member 2 includes a moving bar 45 and a push rod 46. The moving bar 45 is arranged inside the inner arc plate 21 and slidably cooperates with the fixing member 43, so that the moving bar 45 can slide along the radial direction of the inner arc plate 21. An elastic member 2 is provided between the moving bar 45 and the fixing member 43 for driving the moving bar 45 to reset. An elastic member 3 is provided between the friction block 442 and the end of the locking rod 44 for driving the friction block 442 to reset. A push plate 443 is connected to the friction block 442, and the push plate 443 contacts the side of the moving bar 45 toward the axis of the inner arc plate 21. One end of the push rod 46 is fixedly connected to the moving bar 45, and the other end passes through the outer arc plate 22 and extends outward. When the inner arc plate 21 is fully closed, the end of the push rod 46 extending outward can contact the support seat 12 and push the moving bar 45 to move along the radial direction of the inner arc plate 21 toward the direction close to the axis of the inner arc plate 21.

[0047] Specifically, Figures 1 to 8 As shown, during the closing process of the inner arc plate 21, the end of the push rod 46 extending outward will gradually approach the support seat 12 until the end of the push rod 46 contacts the support seat 12. At this time, the inner arc plate 21 is not completely closed. As the inner arc plate 21 continues to close, the end of the push rod 46 is blocked by the support seat 12, which will push the push rod 46 to move in the direction close to the axis of the inner arc plate 21 and drive the moving bar 45 to move synchronously, so that the elastic member 2 is compressed to store force. As the moving bar 45 moves, it will push the push plate 443 to move in the direction close to the axis of the inner arc plate 21, and at the same time drive the friction block 442 The elastic member 3 is compressed to store force, and as the friction block 442 separates from the surface of the thermal insulation belt 31, the friction contact between the friction block 442 and the thermal insulation belt 31 can be released. During the opening of the inner arc plate 21, the movable bar 45 is reset under the action of the elastic member 2, so that the movable bar 45 moves away from the axis of the inner arc plate 21. At this time, the friction block 442 moves away from the axis of the inner arc plate 21 under the action of the elastic member 3, so that the friction block 442 contacts the surface of the thermal insulation belt 31 again, and the friction contact between the friction block 442 and the thermal insulation belt 31 is restored.

[0048] In some embodiments, a movable structure is provided on the mounting plate 11, and a slide groove 111 is provided on the mounting plate 11 along its length direction. The movable structure includes a slide seat 13 slidably arranged in the slide groove 111, and a driving member 3 14 arranged on the mounting plate 11, and the output end of the driving member 3 14 is connected to the slide seat 13, one group of clamping mechanisms is arranged on the slide seat 13, and the other group of clamping mechanisms is arranged at one end of the mounting plate 11.

[0049] Specifically, Figure 1 and Fig. 9As shown, after the forging 1 is clamped by the clamping mechanism, the driving member 3 14 is started, which can drive the slide 13 connected thereto to move along the slide groove 2 111, and drive the clamping mechanism installed on the slide 13 to move, so that the clamping mechanism is close to or away from another group of clamping mechanisms. Through the movement of this group of clamping mechanisms, the forging 1 clamped by it can be driven to move along its own axial direction to change the clamping position of the forging 1, which is beneficial to the processing of the forging 1.

[0050] During the hot forging process, due to the high temperature, the surface of the forging 1 reacts with the oxygen in the air to generate oxide scale. The presence of the oxide scale will reduce the surface quality of the forging 1. If the oxide scale is pressed into the surface of the forging 1, it will cause surface depression and affect the dimensional accuracy. Therefore, the oxide scale needs to be peeled off from the forging 1 before subsequent processing. In some embodiments, the length direction of the mounting plate 11 is defined as the front-to-back direction, the clamping mechanism installed on the slide 13 is clamping mechanism 1, and the other set of clamping mechanisms is clamping mechanism 2. The clamping mechanism 1 can move in the front-to-back direction. The clamping mechanism 2 is installed at the rear end of the mounting plate 11 and is located on the outer arc surface of the inner arc plate 21 at the rear end.
