Description

TECHNICAL FIELD

[0001] The utility model relates to free forging hydraulic press equipment field especially, and it is a kind of clamping device and operating machine based on high-temperature alloy and titanium alloy forging forming. BACKGROUND

[0002] With the rapid development of national defense science and technology, aerospace, chemical industry and other fields, the quality and performance requirements of high-temperature alloy and titanium alloy forgings are increasingly stringent. The key components in these fields often need to operate stably and reliably in extreme harsh environments such as high temperature, high pressure and high stress, which requires high-temperature alloy and titanium alloy forgings to have highly consistent mechanical properties, precise dimensional accuracy and excellent internal structure.

[0003] In the field of material forging technology, free forging has always been an important processing method, and oil press free forging is widely used due to its large forging pressure and good process controllability. Traditional free forging manipulator, whether single manipulator or double manipulator cooperation mode, can complete a series of basic forging processes such as ring blank upsetting, punching, mandrel lengthening, bar pressing, chamfering, upsetting and plate blank upsetting, and realize a variety of actions such as jaw clamping and releasing, jaw rod parallel lifting and seven major actions, basically meeting the functional requirements of general forging.

[0004] However, for high-temperature alloy and titanium alloy, which are extremely sensitive to forging process, the existing free forging manipulator has obvious limitations. Due to the lack of axial rotation and overturning function, when facing the process requirement of directly overturning the axial edge, it is necessary to use secondary clamping. This method relies on the friction between the workpiece and the flat anvil to produce a specified angle (only judged by visual observation) after the manipulator releases the jaw, and then clamps again for forging.

[0005] This traditional indirect overturning forging method causes many problems. First, the secondary clamping operation significantly prolongs the forging time, and for the workpiece at a high temperature of about 1000℃, its heat dissipation is intensified, which destroys the original heat soaking forging conditions of the material, and further causes the strength of the material to change, which has an adverse effect on the stable forging process of the forging machine, and easily causes uneven stress distribution in the workpiece, increasing the risk of defects such as cracks.

[0006] Secondly, the extension of the forging turnover time makes the deformation process of the forged piece under the same heating condition prolonged, which often leads to the low final forging temperature and the need to stop forging, forcing the production process to increase the re-heating link. This not only consumes a large amount of energy and reduces the production efficiency of the equipment, but also may cause the surface oxidation and decarburization of the material due to multiple heating, further affecting the quality of the forged piece.

[0007] Furthermore, the longer forging process and larger forging temperature difference make the deformation temperature difference of different parts of the material under the same forging condition increase, and the grain morphology of the microstructure also have greater differences. Macroscopically, the mechanical properties of the material are inconsistent, the flaw detection grades are uneven, and finally the consistency of the product is poor, which is difficult to meet the requirements of high quality and high stability of the forged piece in high-end fields.

[0008] Finally, the angle between the forged piece and the flat anvil is controlled by visual inspection, which has low precision and is difficult to ensure the forming precision of the forged piece, and is prone to problems such as size deviation and irregular shape, thereby reducing the qualified rate and added value of the product.

[0009] Therefore, a clamping device and operating machine based on high-temperature alloy and titanium alloy forging forming are needed to solve the above problems. Content of the utility model

[0011] To solve the above technical problems, the utility model provides a clamping device based on high-temperature alloy and titanium alloy forging forming, which comprises a force arm, a positioning clamp plate, a horizontal driving part and a rotary driving part.

[0012] The positioning clamp plate is symmetrically arranged at one end of the force arm and can move along the direction of approaching or moving away from each other.

[0013] The positioning clamp plate comprises a first connecting plate connected with the force arm and a second connecting plate rotatably installed on the inner side of the first connecting plate.

[0014] The second connecting plate has a moving part moving along the length direction thereof, and the moving part is used for clamping the forged piece.

[0015] The horizontal driving part is arranged on the second connecting plate and is used for controlling the movement of the moving part.

[0016] The rotary driving part is arranged on the first connecting plate, and the output end is connected with the rotating shaft of the second connecting plate.

[0017] Further, a sliding groove is arranged on the second connecting plate, the moving part has a limiting block matched with the sliding groove, and the horizontal driving part is embedded in the sliding groove and connected with the limiting block.

[0018] Further, the sliding groove and the limiting block are arranged in rectangular structure.

[0019] Further, the maximum distance that the moving part can move on the second connecting plate is 200mm.

[0020] Further, the horizontal driving part is arranged as a pneumatic cylinder.

[0021] Further, the rotating driving part is arranged as a servo motor.

[0022] Further, a screw transmission assembly is arranged on the force arm and connected with the two positioning clamping plates, for controlling the two positioning clamping plates to move in the direction of approaching or moving away from each other.

[0023] Further, the side of the moving part in contact with the forging is arranged as a friction surface.

[0024] In another aspect, the utility model also provides an operating machine, which comprises an operating machine body and the clamping device based on high-temperature alloy and titanium alloy forging forming as described in the above embodiment.

[0025] The force arm is connected with the operating machine body.

[0026] The operating machine body has a control mechanism for controlling the force arm to ascend, descend, form an included angle with the horizontal plane or be parallel to the horizontal plane.

[0027] Compared with the prior art, the utility model has at least the following beneficial effects:

[0028] By arranging the positioning clamping plate comprising the first connecting plate and the second connecting plate, and the moving part on the second connecting plate, the forging can be clamped, and because the moving part can move relative to the second connecting plate, during the forging forming, the horizontal driving part can be operated to finely adjust the forging in the horizontal direction, so that the forging forming quality is improved.

[0029] In addition, by arranging the rotating driving part, the second connecting plate can rotate relative to the first connecting plate, so that when the axial edge of the forging is forged, the rotating driving part can be operated to overturn the forging, so that the situation that the forging condition is damaged or the forging is stopped due to secondary clamping and visual angle measurement in the prior art can be effectively avoided, the forging precision is improved, the manufacturing time is shortened, and the forging process is more stable.

[0034] The clamping device based on high-temperature alloy and titanium alloy forging forming and operating machine of the utility model will be described in more detail below in conjunction with the schematic drawings, wherein the preferred embodiment of the utility model is shown, and it should be understood that the utility model described herein can be modified by those skilled in the art, and the advantageous effects of the utility model can still be achieved. Therefore, the following description should be understood as extensive knowledge for those skilled in the art, and not as a limitation on the utility model.

[0035] The utility model will be described in more detail in the following paragraphs with reference to the drawings. The advantages and features of the utility model will be more apparent according to the following description. It should be noted that the drawings are all very simplified and use non-precise proportions, only to facilitate, clearly assist in the purpose of explaining the embodiment of the utility model.

[0036] Example one

[0037] As shown in Figure 1 and Figure 2 The utility model embodiment proposes a kind of clamping device based on high-temperature alloy and titanium alloy forging forming, including force arm 1, positioning clamp plate 2, horizontal drive 3 and rotary drive 4.

[0038] Wherein, the positioning clamp plate 2 is symmetrically arranged at one end of the force arm 1, and can be moved along the direction of approaching each other or away from each other, for completing the clamping function to forging.

[0039] Specifically, the positioning clamp plate 2 includes the first connecting plate 21 connected with the force arm 1 and the second connecting plate 22 rotatably installed in the inner side of the first connecting plate 21.

[0040] The second connecting plate 22 has a moving part 221 moving along its length direction, which is used for clamping the forging. When the moving part 221 moves relative to the second connecting plate 22, the position of the forging can be fine-tuned synchronously, that is, the forging can be more flexibly aligned with the main body of the forging machine, reducing the energy consumption and action time of the whole manipulator and improving the forging rate.

[0041] In order to improve the clamping effect of the moving part 221 on the forging, the side of the moving part 221 in contact with the forging is provided with a friction surface to increase the friction and ensure the stability of clamping.

[0042] In addition, since the second connecting plate 22 is rotationally connected with the first connecting plate 21, the forging clamped between the two second connecting plates 22 can be rotated synchronously to adjust the overturning amplitude according to the requirements, so as to complete the forging requirements of different angles and positions (such as the corner position of the alloy) of the forging. Compared with the multiple clamping and visual observation angle method in the prior art, the device can overturn to a specific angle required, so the stability and precision are higher, and the forging precision is improved, the manufacturing time is shortened, and the forging process is more stable.

[0043] The horizontal driving part 3 is arranged on the second connecting plate 22 and is used for controlling the movement of the moving part 221.

[0044] In addition, the rotating driving part 4 is arranged on the first connecting plate 21, and the output end is connected with the rotating shaft of the second connecting plate 22 to complete the control of the overturning action of the second connecting plate 22.

[0045] In other embodiments, in order to improve the stability of the moving part 221 when moving the forging, a sliding groove 5 is arranged on the second connecting plate 22, and the moving part 221 has a limiting block 6 matched with the sliding groove 5, so that the moving part 221 can move along the predetermined track under the limiting action of the mutual clamping of the sliding groove 5 and the limiting block 6.

[0046] In addition, the horizontal driving part 3 is embedded in the sliding groove 5 and connected with the limiting block 6, which provides power for the movement of the moving part 221.

[0047] In this embodiment, the sliding groove 5 and the limiting block 6 are both arranged in a rectangular structure, further improving the stability of the moving part 221 when sliding.

[0048] It should be noted that the maximum distance that the moving part 221 can move on the second connecting plate 22 is 200 mm, that is, the moving range of the moving part 221 with the forged piece is between 0 mm and 200 mm, which realizes the fine adjustment of the position of the forged piece and ensures that the forged piece will not affect the overturning of the second connecting plate 22 due to the too long moving distance.

[0049] In one of the examples, the horizontal drive 3 is provided as a gas cylinder, and the rotary drive 4 is provided as a servo motor, so as to realize the accurate control of the overturning angle.

[0050] In further embodiments, the servo motor is further connected with a control system, which can control the servo motor to rotate a specific angle, such as 15°, 30°, and 45°, etc., in one time, so as to realize the one-key control of the servo motor, and facilitate the operation personnel to use.

[0051] In other embodiments, in order to facilitate the control of the two positioning clamping plates 2 to move in the direction of approaching or moving away from each other, a screw transmission assembly is provided on the force arm 1, and the screw transmission assembly is connected with the two positioning clamping plates 2, for controlling the two positioning clamping plates 2 to move in the direction of approaching or moving away from each other, which is the prior art, and thus will not be described here.

[0052] Embodiment Two

[0053] As shown in Figure 3 the embodiment, on the basis of the embodiment one, an operating machine is further provided, which comprises an operating machine body 7 and the clamping device based on the high-temperature alloy and titanium alloy forging and pressing forming as described in the embodiment one.

[0054] The force arm 1 is connected with the operating machine body 7.

[0055] It should be noted that the operating machine body 7 has a control mechanism 71 for controlling the force arm 1 to rise, fall, and form an included angle with the horizontal plane or be parallel to the horizontal plane. The control mechanism 71 is used to lift the force arm 1 to a predetermined height, so as to ensure that the forged piece can have a reserved overturning gap between the forged piece and the forging and pressing table when the second connecting plate 22 overturns relative to the first connecting plate 21, and ensure that there is no interference, and improve the stability during operation.

[0056] It should be noted that the above control mechanism 71 is a conventional hydraulic drive mechanism in the prior art, which is the prior art, and thus will not be described here.

[0057] The device can realize the stable axial rotation and overturning of the forged piece by providing the positioning clamping plate 2 comprising the first connecting plate 21 and the second connecting plate 22, so as to achieve the purposes of improving the forging and pressing precision, shortening the manufacturing time, and making the forging and pressing process more stable.

[0058] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application also intends to include these modifications and variations.
