Description

Technical Field

[0001] The invention relates to the technical field of steel ball cold heading, in particular to a high-speed automatic steel ball cold heading machine. Background Art

[0002] In the production process of steel balls, the metal billet (steel) is first placed in a mold, and then appropriate pressure is applied to cause the billet to undergo plastic deformation in the mold, ultimately obtaining a steel ball that meets the requirements.

[0003] Cold heading is mainly mechanical forced pressing. Due to the high strength of the steel billet, when the steel is processed and transferred to the inner side of the double mold by a robotic arm or fixture, at the moment the mold closes, the local instantaneous pressure on the steel will cause its pressure-bearing end to tilt or incline. When pressed into a ball, the rough ball will have crooked edges. At the same time, the continuous reaction and extrusion of the mold by the hard steel will also cause the rough surface of the inner wall of the mold to increase, which will cause damage to the subsequent surface of the ball.

It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0053] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0054] A high-speed automatic cold heading machine for steel balls provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0055] Example 1:

[0056] Combine Figures 1 to 11As shown, the present invention provides a high-speed automatic cold heading machine for steel balls, comprising a pressure-bearing mechanism 100, a clamping edge stabilizing mechanism 200 arranged in the pressure-bearing mechanism 100, an anti-distortion stamping mechanism 300 arranged in the pressure-bearing mechanism 100, and an auxiliary pressure propulsion mechanism 400 arranged on the anti-distortion stamping mechanism 300, wherein the clamping edge stabilizing mechanism 200 is used to fix the steel ball blank 500, the pressure-bearing mechanism 100 is used to provide compressive support and stretching kinetic energy for the stretching of the anti-distortion stamping mechanism 300 and the auxiliary pressure propulsion mechanism 400, the clamping edge stabilizing mechanism 200 is used to provide calibration constraints for columnar steel, the anti-distortion stamping mechanism 300 is used to cooperate with the clamping edge stabilizing mechanism 200 to mold the columnar steel according to the change of deformation tension, and the auxiliary pressure propulsion mechanism 400 is used to provide loading and unloading driving force for the clamping edge stabilizing mechanism 200.

[0057] The pressure-bearing mechanism 100 includes two pressure-bearing plates 110 , a truss 120 disposed within the two pressure-bearing plates 110 , and a hydraulic component 130 installed in the middle of the truss 120 ;

[0058] Two symmetrically distributed limiting clamps 140 are provided inside the pressure plate 110;

[0059] The card edge stabilization mechanism 200 includes two card seats 260 and two sets of upsetting material calibration components 250, a base plate 210 set on the truss 120, and a separation pad 220 installed in the middle of the base plate 210;

[0060] The upsetting material calibration assembly 250 includes a reinforced outer plate 251, a holder 260 disposed on the exterior of the reinforced outer plate 251, a slot 253 formed in the middle of the reinforced outer plate 251, and a transverse hole 252 formed on the side of the reinforced outer plate 251. A traction rod 254 is disposed within the transverse hole 252, a molded gasket 256 is disposed within the inner side of the slot 253, and a threaded section at the inner end of the traction rod 254 is mounted within the molded gasket 256. A gasket 255 is disposed in the middle of the traction rod 254, and a tension spring 257 is connected to the inner end of the gasket 255.

[0061] A trapezoidal slope is provided on the top of the separation pad 220 , and an inclined groove is provided in the middle of the bottom surface of the reinforcing outer plate 251 , and the trapezoidal slope is adapted to the inclined groove to provide a guide platform for expansion of the two reinforcing outer plates 251 .

[0062] Rectangular transverse grooves are provided on both sides of the inner side of the reinforcing outer plate 251 , and the inner plate surface of the vertical frame 230 fits in the rectangular transverse grooves to provide alignment constraints for the two reinforcing outer plates 251 after closing.

[0063] When the hydraulic component 130 is in operation, as the hydraulic sub-rod inside it contracts, the pushed bracket 390 will apply an outward thrust to the two cantilevers 380. At this time, the two sets of heads 330, the pressure-resistant straight cylinder 310 and the cold heading end head 320 will be withdrawn from the two holders 260. After the cold heading end head 320 is completely withdrawn from the holder 260, the first clamping seat 340 installed on the top of the head 330 will pull the suspension 460 down. At this time, the top pressure slide 450 movably installed on the top of the suspension 460 will apply a downward thrust to the two sets of upsetting material calibration components 250.

[0064] Until the two sets of upsetting material calibration components 250 descend and expand outward along the separation pad 220, the two sets of upsetting material calibration components 250 can provide a calibrated mold cavity for the cylindrical steel;

[0065] After the two sets of forging calibration components 250 clamp and restrain the cylindrical steel and reset it to the initial state, the extension of the hydraulic sub-rod in the hydraulic component 130 can push the two cold forging ends 320 to reset under the linkage action of the above components until the two cold forging ends 320 perform cold forging processing on the two ends of the cylindrical steel.

[0066] Example 2:

[0067] Combine Figure 3 、 Figure 9 as well as Figure 11 As shown, based on the embodiment 1, the card edge stabilization mechanism 200 further includes a reset component 270 , which is used to provide a reset thrust to the reinforced outer plate 251 .

[0068] Preferably, four sets of reset assemblies 270 are arranged between two adjacent reinforcing outer plates 251 and the bottom plate 210. As the two reinforcing outer plates 251 are raised and lowered along the two sides of the two vertical frames 230, the columnar steel can be effectively clamped by the two sets of molded pads 256, that is, the columnar steel can be centered and calibrated.

[0069] Two symmetrically distributed vertical frames 230 are installed at both ends of the bottom plate 210;

[0070] A vertical slot is defined in the vertical frame 230 , and a limiting slide 240 is disposed in the vertical slot.

[0071] Preferably, the two limiting slides 240 are used to provide an orderly trajectory for the lateral extension of the two sets of upsetting material calibration assemblies 250. When the two sets of upsetting material calibration assemblies 250 are squeezed by the separation pad 220 and extend freely, the two limiting slides 240 can provide effective support for the upsetting material calibration assemblies 250.

[0072] The interior of the limiting slide plate 240 is provided with a slot adapted to be constrained by the traction rod 254;

[0073] The reset assembly 270 includes an end plate 275 disposed at the bottom of the reinforcing outer plate 251, a reset inclined rod 273 movably mounted on the end plate 275, and a first spring 274 disposed on the outside of the reset inclined rod 273;

[0074] A cross frame 271 is installed on the outside of the bottom plate 210, and a clamp 272 is movably installed on the outer end of the cross frame 271;

[0075] The bottom end of the reset inclined rod 273 is adapted to penetrate into the interior of the clamp 272 .

[0076] Preferably, the cross frame 271 is fixed to the outside of the base plate 210 by welding, wherein the base plate 210 is welded and fixed to the middle of the truss 120. When the two sets of upsetting material calibration assemblies 250 are lifted and lowered back and forth, the four sets of reset assemblies 270 can provide effective reset thrust for the two sets of upsetting material calibration assemblies 250, thereby improving the loading and unloading efficiency of steel and steel ball blanks 500.

[0077] Example 3:

[0078] Combine Figures 3 to 11 As shown, based on Example 1, the anti-distortion punching mechanism 300 includes a pressure-resistant straight cylinder 310, a cylindrical hole is opened inside the pressure-resistant straight cylinder 310, and a cold heading end 320 is arranged in the cylindrical hole. The cold heading end 320 passes through the cylindrical hole and is provided with a compression spring 370 on the rod body;

[0079] A sealing head 330 is installed at the outer end of the rod body in the cold heading end head 320 . A first clamping seat 340 is provided on the top of the sealing head 330 , and a second clamping seat 350 is provided on the bottom of the sealing head 330 .

[0080] Preferably, the outer end of the inner rod of the cold heading end head 320 is installed in the head 330. The head 330 pulled by the compression spring 370 will push the cold heading end head 320 toward the steel end inside the clamping seat 260 for initial pressure. As the cantilever 380 continues to apply pressure to the second clamping seat 350, the head 330 will eventually apply extrusion pressure to the anti-pressure straight cylinder 310. At this time, the cold heading end head 320 can perform mold processing on the end of the cylindrical steel.

[0081] A plug 360 is provided on the inner side of the sealing head 330, and the plug 360 is adapted to be clamped in the slide groove inside the pressure-resistant straight cylinder 310;

[0082] The second clamping base 350 is movably connected to a cantilever 380 , and a bracket 390 is movably mounted on the bottom end of the cantilever 380 ;

[0083] The pressure-resistant straight cylinder 310, the cold heading end 320 and the head 330 are located on the inner side of the two limiting clamps 140, and the first clamp seat 340 arranged at the top of the head 330 and the second clamp seat 350 arranged at the bottom of the head 330 respectively penetrate the two gaps of the two limiting clamps 140.

[0084] Preferably, two symmetrically distributed arc-shaped inserts are provided on the end of the cold heading end 320 close to the pressure-resistant straight cylinder 310, and the arc-shaped inserts are adapted to pass through the interior of the pressure-resistant straight cylinder 310. With this structural setting, when the cold heading end 320 is pressurized, shaking during the molding process of the steel end can be avoided, and the cylindrical steel can remain stable during the process of being pressed into a ball.

[0085] Example 4:

[0086] Combine Figures 3 to 11 As shown, based on Example 1, the auxiliary pressure propulsion mechanism 400 includes a top support frame 410, a suspension 460 movably mounted outside the first clamping seat 340, and a top pressure sliding column 450 movably mounted on the top of the suspension 460.

[0087] Preferably, the bottom ends of the two suspensions 460 are movably mounted on the two first clamping seats 340, and the cold heading end 320 in the initial state is located in the clamping seat 260. At this time, the two suspensions 460 will form a triangular structure and push the top pressure slide 450 to rise, so that the two sets of upsetting material calibration components 250 can clamp the cylindrical steel and maintain the stability of the molding.

[0088] The top pressure slide column 450 is in a U-shaped structure as a whole, and a slideway is provided inside the top pressure slide column 450;

[0089] The middle part of the top support frame 410 is provided with four evenly distributed end rods 420. A limit vertical rod 430 is installed on the top support frame 410. A second spring 440 is provided on the outside of the limit vertical rod 430, and the top end of the second spring 440 is adapted to bear pressure on the top pressure sliding column 450.

[0090] The bottom ends of the end plates on both sides of the top-pressing sliding column 450 are respectively pressed against the tops of the two reinforcing outer plates 251 .

[0091] Preferably, the width of the end plates on both sides of the top-pressing slide column 450 is the same as the width of the top of the reinforcing outer plate 251. When the reinforcing outer plate 251 is guided outward by the inclined surface of the separating pad 220, the bottom ends of the end plates on both sides of the top-pressing slide column 450 can maintain the two sets of expanded upsetting calibration assemblies 250 to effectively clamp and restrain the cylindrical steel without separating from the top of the reinforcing outer plate 251.

[0092] The top support frame 410 is a T-shaped structure as a whole, and two sockets are opened in the middle of the top support frame 410, and the four end rods 420 are respectively set in the two sockets;

[0093] The top pressure slide 450 is adapted to pass through the two sockets.

[0094] When the top support frame 410 is fixedly installed between the two pressure plates 110, the top support frame 410 can cooperate with the limiting vertical rod 430 to provide sufficiently stable support for the lifting and lowering of the top pressure slide column 450, thereby ensuring that the two cold heading ends 320 are under constant pressure, while preventing the cylindrical steel from tilting inside the two sets of heading calibration components 250.

[0095] The working principle and usage process of the present invention: The steel ball cold heading process is a process in which steel is cut through special processing and pressed into balls using a robotic arm or fixture. The metal blank material is pressed into a spherical rough blank by cold pressing;

[0096] However, the existing steel ball cold heading process has certain defects. During the process of transferring the cut material to the mold through a robotic arm or a fixture and pressing it, the steel material will be tilted and skewed at the moment it contacts the pressure surface, which will cause the steel ball blank 500 to have a skewed edge. This skewed edge will cause the steel ball blank 500 to be larger on one side and smaller on the other.

[0097] In addition, due to the influence of the traditional double pressure of the upper mold and the lower mold, the double mold is subjected to the reaction force of the steel material for a long time, and the roughness of the inner wall of the mold will be aggravated, which will cause the subsequent steel ball rough blank 500 to be stuck;

[0098] The device of the present invention is provided with a four-zone mold structure. When the hydraulic component 130 is in operation, as the hydraulic sub-rod inside it contracts, the bracket 390 installed on the hydraulic sub-rod will push the two cantilevers 380 to extend outward, and the two heads 330 movably installed on the top of the two cantilevers 380 will move laterally outward along the inside of the two sets of limit clamps 140. At this time, the two cold heading ends 320 will be withdrawn outward from the inside of the two clamping seats 260.

[0099] After the two cold heading ends 320 are completely withdrawn from the two clamping seats 260, the suspension 460 pulled by the first clamping seat 340 will pull the top pressure slide 450 downward, and the top pressure slide 450 constrained by the top support frame 410 and the four end rods 420 will push the two sets of upsetting material calibration assemblies 250 downward. Finally, the two reinforcing outer plates 251 will be pressed down, and the separation pad 220 can press the two reinforcing outer plates 251 until they are separated. At this time, the two sets of upsetting material calibration assemblies 250 can expand with the separation pad 220 as the center.

[0100] Then, a robotic arm or a clamp can be used to deliver the processed cylindrical steel material into the gap between two adjacent sets of molded pads 256. At this time, the two sides of the cylindrical steel material outside the center position can be calibrated and clamped.

[0101] As the hydraulic sub-rod in the hydraulic part 130 extends, the two sets of upsetting material calibration assemblies 250 can transfer the clamped steel upward until the two sets of upsetting material calibration assemblies 250 are close to the middle of the steel. When the two cold heading ends 320 are quickly reset toward the two holders 260, the two ends of the cylindrical steel can finally be pressed by the spherical mold cavity formed by the inner ends of the two cold heading ends 320 and the four molded pads 256, thereby avoiding the phenomenon of skewness or inclination during the cold upsetting of the cylindrical steel. At the same time, the four-zone mold can adapt the pressure-bearing constraints to the parts of the steel that are compressed and deformed, thereby avoiding the problem of jamming of the steel ball blank 500.

[0102] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and alterations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
