Description

Technical Field

[0001] The present invention relates to the field of upset forging machine hammers, and particularly to a hydraulic upset forging machine hammer device. Background Art

[0002] A radial forging machine is a precision rotary forging device specifically designed for manufacturing solid or hollow long shaft parts. Its working principle and operation process embody a high degree of technicality and professionalism. The device uses a series of precisely arranged hammers, which are usually distributed circumferentially around the workpiece bar to be processed, generally between 2 and 8 in number, to perform rapid and precise radial forging on the workpiece.

[0003] During the operation, these hammers are symmetrically distributed around the blank and forge the blank with extremely high frequency and synchronism. At the same time, the blank rotates under the action of a specific driving device and is axially fed under the push of another driving system. This combination of rotational and feeding movements enables the blank to be uniformly subjected to forces from all directions when being forged by the hammers, thereby achieving a gradual reduction in cross-sectional size and axial elongation.

[0004] The radial forging machine hammer, as the core component of the device, undertakes the key task of precisely hammering and plastically forming the material. Through precise design, these hammers can flexibly adjust the striking force and frequency according to needs to ensure an ideal forming effect during forging. They are firmly installed on the forging mechanical structure, and a certain mass of heavy objects is equipped on the top of the hammer, so that sufficient kinetic energy and speed can be released during each hammer strike to effectively compress and shape the material, thereby ensuring that the finally forged parts have excellent quality and performance.

[0005] However, the radial forging machine hammers in the prior art can only forge the same type of shaft. Although they can be adjusted for shafts with different diameters, special-shaped hammers are often required when processing tapered shafts, and different machines have to be used, which results in the lack of applicability of the current forging machine hammers and cannot meet the processing of more different types of shafts. Based on this, the present invention proposes a hammer that can adapt to different shaft shapes to solve the defects of the prior art. Summary of the Invention

[0006] In view of the above technical problems, the present invention discloses a hydraulic upsetting machine hammer head device, which includes a circular bracket. An angle adjustment component and an upsetting component are installed on the circular bracket. The angle adjustment component includes a rotating support rod, which is hinged on the first side of the circular bracket. The rotating support rod is internally provided with an upsetting component, and the angle of hammer forging is adjusted by the rotation of the rotating support rod. Through the above technical solution, the hammer forging angle can be adjusted according to requirements. When processing a tapered shaft, the shaft can be forged from the front, the force is more uniform, the forging effect is better, and the quality of the shaft is improved.

[0007] Further, an angle adjustment rod is hinged on the rotating support rod, and an adjustment slider is hinged on the angle adjustment rod. An installation plate and an adjustment chute are fixedly installed on the circular bracket. The adjustment slider is slidably installed in the adjustment chute, and the angle of the rotating support rod is adjusted by driving the adjustment slider.

[0008] Further, a large gear ring is rotatably installed on the second side of the circular bracket. An adjustment gear is rotatably installed on the installation plate and meshes with the large gear ring. An adjustment lead screw is fixedly installed on the adjustment gear. A threaded hole is provided in the adjustment slider and is matched with the adjustment lead screw;

[0009] An adjustment motor is fixedly installed on the circular bracket. A driving gear is fixedly installed on the rotating shaft of the adjustment motor and meshes with the large gear ring. In the present invention, the rotation of the large gear ring can drive a plurality of adjustment gears simultaneously, adjust all the rotating support rods at the same time, ensure the angle synchronization, and the use of the adjustment lead screw to drive the adjustment gear to move a more accurate distance, with high adjustment accuracy and self-locking characteristics, preventing the angle from automatically changing after adjustment. Therefore, the accuracy of the final forging can be ensured and the processing quality is improved.

[0010] Further, the upsetting component includes a hammer forging center rod, which is slidably installed in the rotating support rod. A hammer head is fixedly installed at the bottom end of the hammer forging center rod for forging.

[0011] Further, an angle measuring plate one and an angle measuring plate two are respectively slidably installed on both sides of the hammer forging center rod. Small vertical plates one and two are fixedly installed at the bottom ends of the angle measuring plate one and the angle measuring plate two. The bottom ends of the small vertical plate one, the hammer head, and the small vertical plate two coincide and are distributed in sequence along the axial direction.

[0012] Further, a lengthening plate is fixedly installed at the bottom end of the small vertical plate one. Through the above technical solution, when processing a shaft with a shoulder, it can be measured by the small vertical plate one and the small vertical plate two. There is a drop between the position where the hammer head forges and the small vertical plate two. The drop can be seen from the position indicating the scale of the angle measuring plate two to ensure the accuracy of forging. The bottom surface of the lengthening plate can contact the thinner part of the shaft, and the hammer head forges the thicker part.

[0013] Further, scales are provided on the hammer forging center rod, and the first angle measurement plate and the second angle measurement plate correspond to the scales.

[0014] Further, a hydraulic cylinder is fixedly installed on the rotating support rod. The hydraulic cylinder drives the hammer forging center rod through an adjustment mechanism, and the adjustment mechanism can adjust the stroke of the movement of the hammer forging center rod.

[0015] Further, the adjustment mechanism includes a motor base fixedly installed on the hammer forging center rod. A spacing motor is fixedly installed on the motor base, and a spacing cam is fixedly installed on the rotating shaft of the spacing motor. The spacing cam is oval-shaped;

[0016] A hammer forging plate is fixedly installed on the cylinder arm of the hydraulic cylinder. The hammer forging plate contacts the top end of the spacing cam, and a hammer forging spring is fixedly installed between the hammer forging center rod and the hammer forging plate. The spacing cam in the present invention is oval-shaped, and the vertical distance can change during rotation. The part with the most accurate and largest force in the hydraulic cylinder is limited, and an excessive stroke is not conducive to hammer forging and cannot ensure consistent hammer forging quality. Therefore, adjustment is carried out through the spacing cam, so that even if the stroke of the hydraulic cylinder remains unchanged, the hammer forging distance can be changed.

[0017] Further, the four surfaces of the circumference of the spacing cam are flattened for fitting with the hammer forging center rod.

[0018] The beneficial effects of the present invention compared with the prior art are as follows:

[0019] (1) Through the technical solution of the present invention, the hammer forging angle can be adjusted according to requirements. It can not only process ordinary shafts, but also perform frontal hammer forging on shafts with tapers during processing, with more uniform force and better hammer forging effect, improving the quality of the shafts.

[0020] (2) Through the technical solution of the present invention, the rotation of the large gear ring can drive multiple adjusting gears simultaneously, adjust all the rotating support rods at the same time to ensure angle synchronization, and use the adjusting lead screw to drive the adjusting gears to move more precisely, with high adjustment accuracy and a self-locking characteristic to prevent automatic change after angle adjustment. Therefore, the accuracy of the final hammer forging can be ensured, improving the processing quality.

[0021] (3) Through the technical solution of the present invention, when processing a shaft with a shaft shoulder, it can be measured through the first small vertical plate and the second small vertical plate. There is a drop between the position where the hammer head performs hammer forging and the second small vertical plate. The drop can be seen from the position indicating the scale of the second angle measurement plate to ensure the accuracy of hammer forging. The bottom surface of the lengthening plate can contact the thinner part of the shaft, and the hammer head performs hammer forging on the thicker part.

[0022] (4) Through the technical solution of the present invention, the spacing cam is oval, and the vertical distance can change during rotation. The part in the hydraulic cylinder that receives the most accurate and greatest force is limited. An overly long stroke is not conducive to hammer forging and cannot ensure consistent hammer forging quality. Therefore, adjustment is carried out through the spacing cam, so that even if the stroke of the hydraulic cylinder remains unchanged, the distance of hammer forging can be changed, and the flat cut on the circumference of the spacing cam can ensure stability and prevent the hammer forging plate from falling off when it is pressed down.

Detailed Description of the Embodiment

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0032] As Figures 1 - 7 shown, a hydraulic upset forging machine hammer head device includes a circular bracket 3. An angle adjustment assembly 1 and a upset forging assembly 2 are installed on the circular bracket 3. The angle adjustment assembly 1 can adjust the forging angle. When processing a common shaft, the forging angle coincides with the radial direction of the circular bracket 3. If a shaft with a taper needs to be processed, the angle can be adjusted through the angle adjustment assembly 1. The upset forging assembly 2 can monitor the drop when processing the shaft shoulder position to ensure the precision of fine machining.

[0033] In this embodiment, the angle adjustment assembly 1 includes four rotating support rods 101. The rotating support rods 101 are hinged on the first side of the circular bracket 3. Three slots are provided on the first side of the circular bracket 3, and there are shafts in the slots. The rotating support rods 101 rotate on the shafts, and then a circular cover plate 4 is installed for protection. The upset forging assembly 2 is installed in the rotating support rods 101, and the forging angle is adjusted by the rotation of the rotating support rods 101. Through the above technical solution, the forging angle can be adjusted according to requirements. When processing a shaft with a taper, the shaft can be forged directly, with more uniform force and better forging effect, improving the quality of the shaft. An angle adjustment rod 102 is hinged on the rotating support rod 101. A connecting ear 103 is fixedly installed on the rotating support rod 101. The angle adjustment rod 102 is hinged to the rotating support rod 101 through the connecting ear 103. An adjustment slider 104 is hinged on the angle adjustment rod 102. An installation plate 105 and an adjustment chute 111 are fixedly installed on the circular bracket 3. The adjustment slider 104 is slidably installed in the adjustment chute 111, and the angle of the rotating support rod 101 is adjusted by driving the adjustment slider 104.

[0034] In this embodiment, a large gear ring 107 is rotatably installed on the second side of the circular bracket 3. An adjustment motor 109 is fixedly installed on the circular bracket 3. A driving gear 108 is fixedly installed on the rotating shaft of the adjustment motor 109. The driving gear 108 meshes with the large gear ring 107. An adjustment gear 106 is rotatably installed on the mounting plate 105 and meshes with the large gear ring 107. The large gear ring 107 drives the four adjustment gears 106 to rotate. An adjustment lead screw 110 is fixedly installed on the adjustment gear 106. The adjustment lead screw 110 is rotatably installed on the mounting plate 105. A threaded hole is provided in the adjustment slider 104 and is matched with the adjustment lead screw 110. Through the above technical solution, the rotation of the large gear ring 107 can drive multiple adjustment gears 106 at the same time, adjust all the rotating support rods 101 at the same time, ensure the angle synchronization, and the use of the adjustment lead screw 110 to drive the adjustment gear 106 to move a more accurate distance, with high adjustment accuracy and a self-locking characteristic to prevent the angle from automatically changing after adjustment. Thereby, the accuracy of the final hammer forging can be ensured, and the processing quality is improved. Start the adjustment motor 109 to drive the driving gear 108, drive the adjustment gear 106 to rotate through the large gear ring 107, the adjustment gear 106 drives the adjustment lead screw 110 to rotate, the adjustment lead screw 110 drives the adjustment slider 104 to slide in the adjustment chute 111, and then the adjustment slider 104 drives the angle adjustment rod 102 and then drives the rotating support rod 101, thereby completing the angle adjustment.

[0035] In this embodiment, the radial forging assembly 2 includes a hammer forging center rod 207. The hammer forging center rod 207 is slidably installed in the rotating support rod 101. A hammer head 215 is fixedly installed at the bottom end of the hammer forging center rod 207 for hammer forging. Angle measuring plates 208 and 209 are slidably installed on both sides of the hammer forging center rod 207. Small vertical plates 211 and 214 are fixedly installed at the bottom ends of the angle measuring plates 208 and 209. The bottom ends of the small vertical plate 211, the hammer head 215, and the small vertical plate 214 coincide and are distributed in sequence along the axial direction. When processing shafts with different diameters, the shaft closer to the clamping device is thicker, so the small vertical plate 214 is closer to the shaft. The small vertical plate 214 and the angle measuring plate 209 are fixed by a small horizontal plate 213. The small vertical plate 211 is fixed to the angle measuring plate 208 by a small horizontal plate 210.

[0036] A lengthening plate 212 is fixedly installed at the bottom end of the first small vertical plate 211. Through the above technical solution, when machining a shaft with a shoulder, the first small vertical plate 211 and the second small vertical plate 214 can be used for measurement. There is a drop between the position where the hammer head 215 forges and the second small vertical plate 214. The drop can be seen by indicating the position of the scale 216 through the second angle measuring plate 209 to ensure the accuracy of forging. The bottom surface of the lengthening plate 212 can contact the thinner part of the shaft, and the hammer head 215 forges the thicker part. A scale 216 is provided on the forging center rod 207, and the first angle measuring plate 208 and the second angle measuring plate 209 correspond to the scale 216. A hydraulic cylinder 201 is fixedly installed on the rotating support rod 101. The hydraulic cylinder 201 drives the forging center rod 207 through an adjusting mechanism, and the adjusting mechanism can adjust the stroke of the movement of the forging center rod 207.

[0037] In this embodiment, the adjusting mechanism includes a motor base 204. The motor base 204 is fixedly installed on the forging center rod 207. A spacing motor 205 is fixedly installed on the motor base 204. A spacing cam 206 is fixedly installed on the rotating shaft of the spacing motor 205. The spacing cam 206 is oval-shaped, and the four circumferential faces are flattened to fit the forging center rod 207. A forging plate 202 is fixedly installed on the cylinder arm of the hydraulic cylinder 201. The forging plate 202 contacts the top end of the spacing cam 206. A forging spring 203 is fixedly installed between the forging center rod 207 and the forging plate 202. Through the above technical solution, the spacing cam 206 is oval-shaped, and the vertical distance can change during rotation. The part with the most accurate and largest force in the hydraulic cylinder 201 is limited. An overly long stroke is not conducive to forging and cannot ensure consistent forging quality. Therefore, adjustment is carried out through the spacing cam 206, so that even if the stroke of the hydraulic cylinder 201 remains unchanged, the forging distance can be changed.

[0038] The present embodiment proposes a hydraulic radial forging machine hammer device, and its specific working principle is: the shaft to be processed is clamped by a clamping device, which can rotate and feed. Before hammer forging, it is first determined what type of shaft to be processed. In the present embodiment, shafts with shoulders of different diameters are used as examples. First, the adjusting motor 109 is started, and the adjusting motor 109 drives the active gear 108, and the active gear 108 drives the large gear ring 107. The large gear ring 107 rotates and drives the adjusting gear 106. The adjusting gear 106 drives the adjusting slider 104 through the adjusting screw 110. The adjusting slider 104 drives the rotating support rod 101 to adjust the angle through the angle adjustment rod 102, and then adjusts the spacing cam 206, starts the spacing motor 205, and the spacing motor 205 drives the spacing cam 206 to rotate, and the hammer forging center rod 207 and the hammer forging plate 202 are respectively fitted with the lower end and upper end of the spacing cam 206. At this time, it is adjusted to the hammer forging plate 202 and the hammer forging center rod 207 is the farthest, and then the hydraulic cylinder 201 is started. The hydraulic cylinder 201 drives the hammer forging plate 202, and the hammer forging plate 202 moves downward through the spacing cam 206 and the hammer forging center rod 207. The circumferential cutting of the spacing cam 206 can ensure stability and will not fall off when the hammer forging plate 202 is pressed downward. When moving downward, the small horizontal plate 1 210 and the small horizontal plate 2 213 are stuck on the upper end of the hammer head 215, and then the extension plate 212 contacts the shaft, and then the hammer head 215 also contacts the shaft for hammer forging. After a period of time, the hammer forging position forms a shaft shoulder with other positions, and the extension plate 212 and the hammer head 215, and the small vertical plate 214 and the hammer head 215 also form a drop. Because the small vertical plate 214 is in a position that has not been hammer forged, there is a drop, and it can be read through the scale 216. When processing a rougher position, adjust the spacing cam 206 to make the hammer forging plate 202 and the hammer forging center rod 207 closer, and then gradually perform hammer forging.
