Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ring-shaped workpiece forging device, in particular to a ring-shaped workpiece forging device based on a forging press. BACKGROUND

[0002] When the workpiece is forged by the forging press, the traditional way is to turn over and move the workpiece by the forging device when the workpiece is forged, and then place the workpiece on the die for forging forming. However, in actual use, in order to reduce the vibration force of the workpiece on the clamping arm during forging, the clamping arm is loosened to release the clamping of the workpiece, but this will cause the overall shape of the forged workpiece to be poor, so the clamping of the workpiece can only be maintained, but the parts of the forging device are frequently maintained and regularly replaced to ensure that the forging device can work normally.

[0003] When the cylindrical workpiece is rotated and forged, the forging device needs to rotate and forge the workpiece. The traditional way of rotating the workpiece is to clamp the edge of the workpiece by the clamping arm, lift the clamping arm upward, loosen the clamping arm after clamping the workpiece, and make the workpiece rotate along the contact point of the clamping arm to realize the rotation of the workpiece. However, by this rotation method, it is difficult to control the height of lifting upward, and it is also difficult to control the distance of loosening the clamping arm appropriately, and the rotation angle deviation is often large. The rotation angle is poor, which has no effect on the initial rotation forging, but in the last circle of rotation forging, the workpiece needs high roundness, which reduces the feed amount of the tool during subsequent turning and causes time waste. And the better the roundness, the less steel material used in forging, which is beneficial to saving material and time cost in production. And the convex-concave thickness of the traditional clamping rotation is large, which is not convenient for subsequent processing.

[0004] Therefore, it is necessary to design a ring-shaped workpiece forging device based on a forging press, which can reduce the vibration transmission to the clamping arm during forging, and can improve the rotation accuracy of the workpiece, so that the overall roundness of the forged workpiece is good.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] ​Embodiment one: the application provides a ring-shaped workpiece forging device based on a forging press, which comprises a base 2 for placing a workpiece 1 and a clamping arm 3 for overturning and moving the workpiece 1. When forging is generally carried out, the workpiece 1 is placed on the base 2, the workpiece 1 is clamped and overturned by the clamping arm 3, and then the workpiece 1 is hammered by the forging press above the base 2, so as to forge the workpiece 1 into the required shape. However, when the workpiece 1 is forged, two common problems may occur. First, when the workpiece 1 is horizontally placed and forged, the clamping arm 3 clamps the workpiece 1, which may cause the clamping arm 3 to vibrate during forging, thereby damaging the clamping arm 3 over a long period of time. However, if the workpiece 1 is not clamped, the workpiece 1 may be offset during forging, thereby reducing the forging quality. Second, when the workpiece 1 is vertically placed and forged while being rotated, the rotation accuracy of the workpiece 1 is low, which may result in poor overall roundness of the forged workpiece 1, thereby being not conducive to subsequent processing. Therefore, the following structure is designed to save the above two problems. As shown in Figures 1-7 two elastic clamping arms 4 and two elastic arm overturning mechanisms 5 are respectively installed on the two clamping arms 3. The elastic arm overturning mechanism 5 is fixedly installed on the clamping arm 3, and is used to drive the elastic clamping arm 4 to rotate. The elastic clamping arm 4 is fixedly installed on the elastic arm overturning mechanism 5, and is used to clamp the workpiece 1. In order to enable the clamping arm 3 to still maintain the original function, it is necessary to enable the elastic clamping arm 4 to move to a position that does not block the clamping arm 3 when the elastic clamping arm 4 does not clamp the workpiece 1. When the elastic clamping arm 4 needs to clamp the workpiece 1, the working end of the elastic clamping arm 4 needs to move to the front side of the clamping arm 3, and then quickly contact the workpiece 1 for clamping, thereby solving the first problem and reducing the vibration of the clamping arm 3. Therefore, the elastic clamping arm 4 can be driven to rotate by the elastic arm overturning mechanism 5, so as to switch the position of the working end of the elastic clamping arm 4, and enable the clamping arm 3 to maintain the original function, i.e., the ability to rigidly contact and clamp the workpiece 1 and the die. As shown in Figure 3 the position is that the elastic clamping arm 4 is retracted upward by the elastic arm overturning mechanism 5, and the ball head 4a can be located above the clamping arm 3.

[0031] The specific structure: The elastic clamping arm 4 includes two ball heads 4a, two elastic push rods 4b, and two dampers 4c. The two elastic push rods 4b are fixedly mounted on the rotating seat of the elastic arm flipping mechanism 5. The two ball heads 4a are respectively fixedly mounted on the ends of the two elastic push rods 4b. Through the contact between the two ball heads 4a and the workpiece 1, the workpiece 1 is clamped between the two ball heads 4a. The two elastic push rods 4b are tilted inwards. During the upward rotation of the elastic push rods 4b to a horizontal position, the elastic push rods 4b are in a compressed state, meaning they can clamp the workpiece 1 more tightly. The workpiece 1 can be clamped through the four ball heads 4a on the two elastic clamping arms 4, and during the clamping process, the four ball heads 4a can automatically adjust the workpiece 1 to the center position.

[0032] Among them, such as Figure 4 As shown, when it is necessary to rotate a vertically placed workpiece 1, the workpiece 1 is clamped by four ball heads 4a, and then rotated by the spring arm flipping mechanism 5, causing the clamped workpiece 1 to be lifted upward. A misaligned pushing mechanism 6 is fixedly installed on the rotating seat of the spring arm flipping mechanism 5. The misaligned pushing mechanism 6 is equipped with a long push rod 6a and a short push rod 6b, which are used to push the two elastic push rods 4b to retract respectively. After the workpiece 1 is lifted, the long push rod 6a is driven by the misaligned pushing mechanism 6 to first contact one of the elastic push rods 4b, causing the ball heads 4a to separate from the workpiece 1. Since the other elastic push rod 4b maintains the clamping of the workpiece 1, the workpiece 1 rotates around the clamping point, thus achieving the rotation of the workpiece 1. It needs to be explained that the total frictional force between the two ball heads 4a and the workpiece 1 is X+X. X+X is sufficient to clamp the workpiece, but when one X of the frictional force is lost, the workpiece cannot be fixedly clamped, allowing the workpiece 1 to rotate around one of the ball heads. Furthermore, even with only one ball head, if the clamping force of that ball head is 2X, it is insufficient to clamp the workpiece; the workpiece will still rotate because its center of gravity is not at the center of the clamping position but at an off-center position. This means that those skilled in the art will understand that when one ball head separates from the workpiece, the clamping action of the other ball head will cause the workpiece to rotate around the clamping point. Finally, the short push rod 6b pushes the other elastic push rod 4b to separate from the workpiece 1, completely releasing the clamping force on the workpiece 1. At this point, the spring arm flipping mechanism 5 pushes the entire assembly to rotate and reset. Then, the offset pushing mechanism 6 releases the support for the elastic push rod 4b, allowing the two ball heads 4a to re-clamp and contact the workpiece 1. Figure 5 As shown, the elastic push rod 4b is in an uncompressed state, as... Figure 6 As shown, the elastic push rod 4b is in a compressed state. Figure 7 As shown, the elastic push rod 4b is in a compressed state. The spring arm flipping mechanism 5 pulls the ball head 4a to rotate, and in this state, the workpiece 1 is lifted upward.

[0033] In order to be able to have enough thrust, such as Figure 3 And Figure 8 As shown, the elastic arm turnover mechanism 5 includes turnover seat 5a, rotating pull mechanism 5b, rotating seat 5c and rotating seat 5d, rotating seat 5c and rotating seat 5d are fixedly installed on the clamping arm 3, the turnover seat 5a is rotatably connected with the rotating seat 5c, the rotating pull mechanism 5b is rotatably connected with the rotating seat 5d, the pulling end of the rotating pull mechanism 5b is hingedly connected with the top of the turnover seat 5a, the elastic push rod 4b, the staggered push open mechanism 6 and the damper 4c are all installed on the turnover seat 5a. By pulling the turnover seat 5a along the rotating seat 5c through the rotating pull mechanism 5b, the elastic push rod 4b can be rotated, so that the ball head 4a can lift the workpiece 1 upward when the workpiece 1 is placed vertically, and at the same time drive the staggered push open mechanism 6 to move, so that the staggered push open mechanism 6 always maintains a position capable of pushing the elastic push rod 4b to move.

[0034] In order to resist the spring 4b2 to have stronger elastic resistance force, such as Figure 9 As shown, each elastic push rod 4b includes a square slide column 4b1, a resistance spring 4b2, a connecting plate 4b3 and a limiting plate 4b4, the turnover seat 5a is slidably connected with the square slide column 4b1, the turnover seat 5a is provided with a square hole for the square slide column 4b1 to slide, the ball head 4a is fixedly installed on the left end of the square slide column 4b1, the limiting plate 4b4 is fixedly installed on the right end of the square slide column 4b1, the resistance spring 4b2 is used to provide a pushing force for the connecting plate 4b3 away from the turnover seat 5a, the resistance spring 4b2 is sleeved on the square slide column 4b1, one end of the resistance spring 4b2 is in contact with the connecting plate 4b3, and the other end is in contact with the turnover seat 5a. It should be noted that in this scheme, there is no elastic force adjusting mechanism 8 side, the resistance spring 4b2 can only contact with the turnover seat 5a, Figure 9 As shown, the square slide column 4b1 is in contact with the elastic force adjusting mechanism 8, the damper 4c is fixedly installed on the turnover seat 5a, the working end of the damper 4c is fixedly connected with the connecting plate 4b3, and the limiting plate 4b4 is in contact with the long push rod 6a and the short push rod 6b when the long push rod 6a and the short push rod 6b are pushed, the top of the limiting plate 4b4 protrudes from the top of the turnover seat 5a, and the limiting plate 4b4 on the two elastic push rods 4b can be contacted when the long push rod 6a and the short push rod 6b are pushed horizontally. When the ball head 4a is pressed, the resistance spring 4b2 will be compressed, so that when the workpiece 1 is lifted upward, the ball head 4a and the workpiece 1 have strong extrusion force friction. The extrusion force generated during the forging of the workpiece 1 will be damped by the resistance spring 4b2, and will be damped by the damper 4c, thereby increasing the service life of the equipment.

[0035] In order to be able to increase the elastic force of the resistance spring 4b2 on the workpiece 1 on the basis of avoiding affecting the extrusion position of the ball head 4a and the workpiece 1, for this purpose, as Figure 9As shown, the elastic force adjusting mechanism 8 is fixedly installed on the turnover seat 5a, and is used to push the contact spring 4b2 to compress towards the connecting plate 4b3, so that the ball head 4a can provide stronger elastic extrusion force to the workpiece 1 when being compressed in contact with the workpiece 1, while keeping the original displacement and the compression amount of the contact spring 4b2 unchanged, because the initial contact spring 4b2 is in a compressed state, i.e. the elastic force of the contact spring 4b2 applied to the ball head 4a is increased.

[0036] As shown in Figure 3 , the misalignment pushing mechanism 6 includes an electro-hydraulic push rod 6c and a mounting plate 6d, the electro-hydraulic push rod 6c is fixedly installed on the turnover seat 5a, the mounting plate 6d is fixedly connected with the output end of the electro-hydraulic push rod 6c, and the short push rod 6b and the long push rod 6a are both fixedly connected with the mounting plate 6d. In the initial position, the bottom of the long push rod 6a is in contact with the top of the turnover seat 5a, so as to avoid extrusion rotation of the long push rod 6a when being pushed. The mounting plate 6d is pulled by the electro-hydraulic push rod 6c, so that the mounting plate 6d synchronously drives the short push rod 6b and the long push rod 6a to move, and the long push rod 6a and the short push rod 6b can push the two limiting plates 4b4 to move step by step, so that the workpiece 1 can rotate first and then separate. Figure 10 and Figure 11 As shown in Figure 11 , when one of the ball heads (point A) is released, it will rotate along the trajectory of F (i.e. rotate around point B). The height is constant, so that the angle of rotation can be accurately controlled. Finally, the ball head 4a on point B is also released, so that it will not collide with the workpiece 1 when being reset.

[0037] As shown in Figure 8 , the rotating pulling mechanism 5b includes an electro-hydraulic push rod 5b1 and a hinged seat 5b2, the bottom of the electro-hydraulic push rod 5b1 is hinged with the first rotating seat 5d, the hinged seat 5b2 is fixedly installed on the output end of the electro-hydraulic push rod 5b1, and the hinged seat 5b2 is hinged with the back of the turnover seat 5a. The hinged seat 5b2 is pulled by the electro-hydraulic push rod 5b1, so that the hinged seat 5b2 can pull the turnover seat 5a to rotate, i.e. realize the rotation of the turnover seat 5a. The electro-hydraulic push rod 5b1 can be a double-cylinder electro-hydraulic push rod, or two electro-hydraulic push rods are spliced together.

[0038] In order to reduce the vibration force received by the rotating pulling mechanism 5b, as shown in Figure 8 , when the rotating pulling mechanism 5b is in the initial position, the turnover seat 5a is in contact with the first rotating seat 5c, and the turnover seat 5a and the first rotating seat 5c are provided with inclined surfaces which are in contact with each other. When the turnover seat 5a is vibrated, the vibration can be transmitted to the first rotating seat 5c through the turnover seat 5a, so as to reduce the vibration transmitted to the rotating pulling mechanism 5b.

[0039] Embodiment two: the difference from embodiment one is that, as shown in Figure 9 The elastic adjusting mechanism 8 includes a stop plate 8a and a screw 8b, the screw 8b engages with the turnover seat 5a, the turnover seat 5a is provided with a threaded hole engaging with the screw 8b, the stop plate 8a is in sliding connection with the square slide column 4b1, one end of the square slide column 4b1 is in abutment with the stop plate 8a, and the screw 8b is in rotational connection with the stop plate 8a. By rotating the screw 8b, the stop plate 8a can compress and release the abutment spring 4b2, that is, the extrusion force between the ball head 4a and the workpiece 1 is adjusted.

[0040] In use, when the elastic clamping arm 4 needs to clamp the workpiece 1, the elastic clamping arm 4 is pushed to the position shown in Figure 2 by the elastic arm turnover mechanism 5, and then the workpiece 1 is clamped and aligned by the elastic clamping arm 4.

[0041] If the workpiece 1 needs to be rotated and forged, the elastic clamping arm 4 is moved to the state shown in Figure 5 , then the two clamping arms 3 continue to extrude inward, so that the elastic clamping arm 4 is compressed to the state shown in Figure 6 , then the elastic clamping arm 4 rotates upward to lift the workpiece 1 to the state shown in Figure 7 , finally the misaligned pushing mechanism 6 is used to push, so that the two ball heads 4a are separated from the workpiece 1 step by step, that is, the workpiece 1 is first rotated and then separated, finally the elastic clamping arm 4 is pushed to reset by the elastic arm turnover mechanism 5, and the above process is repeated to continuously rotate the workpiece 1.

[0042] 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.
