Description

Technical Field

[0001] The invention relates to the technical field of blank conveying equipment, in particular to a blank conveying device of a high-speed rail roller cold heading forming machine. Background Art

[0002] Rollers are the components that bear loads when the bearing is running. They are the weakest parts in roller bearings. Their manufacturing quality has a great influence on the working performance of the bearing (such as rotation accuracy, vibration, noise and flexibility, etc.) and is the main factor affecting the service life of the bearing. There are many types of rollers, which can be divided into tapered rollers, cylindrical rollers, spherical rollers, spiral rollers and various types of needle rollers according to their shapes and sizes.

[0003] Before cold heading, the roller blank needs to go through the steps of cutting, forming, cutting and grinding. The purpose of blank grinding is to remove surface burrs and ensure the smoothness of the cross section. Since the cold heading forming process mainly adopts cold shearing, it is necessary to ensure that each blank will not have shape deformation or appearance defects, so as to avoid the defects of problematic blanks being further magnified after cold heading forming.

[0004] However, the existing blank conveying equipment has the following shortcomings: After processing, the long bar material is cut into multiple roller blanks in sequence according to the required specifications under the work of the cutting machine. Since multiple roller blanks are polished in batches, multiple blanks contact and collide with the polishing components in the machine, which may cause some blanks to be deformed or the end faces to be hit and cause material loss. However, the existing blank conveying equipment is limited by its own structure and has relatively single functions. It is impossible to check the status of each blank one by one, resulting in a large amount of residual material conveyed into the cold heading forming machine, which seriously affects the roller acquisition amount and further slows down the efficiency of subsequent processes.

[0005] Therefore, we propose a blank conveying device for a high-speed rail roller cold heading forming machine to solve the above-mentioned problems. Summary of the invention

[0006] The object of the present invention is to provide a blank conveying device for a high-speed rail roller cold heading forming machine. Through the provided induction sorting mechanism and the material selection mechanism, each wiring shield is first transferred to the discharge window in turn to complete the placement of the blank. After the blank enters the wiring shield, its outer wall can fully contact the touch sensor arranged therein. During the process, the touch sensor can fully cover the surface of the blank. If the shape of the blank in a certain wiring shield is irregular, the equipment system controls the connected drive assembly to quickly release the blank in the wiring shield. If the detection result is normal, the transmission assembly transfers the blank to the top of the fourth electric push rod to complete the blank hoisting, and finally discharges it from the inclined funnel to the feed of the cold heading forming machine to solve the problems raised by the above background technology.

The rotation range of each time is set within the angle range of each two outer open ring grooves. First, each wiring shield is transferred to the discharge window in turn to complete the placement of the blank. Because the inner shaft of each wiring shield is adapted to the conveyed blank, after the blank enters the wiring shield, its outer wall can fully contact with the touch sensor set therein. During the process, the touch sensor can fully cover the surface of the blank. If the shape of the blank in a certain wiring shield is irregular, it cannot contact the inner wall of the corresponding touch sensor. If the attachment is sufficient, there will be a missing sensing surface. The signal obtained will be fed back to the equipment system in time to control the connected drive components to quickly release the blank in the wiring shield. If the test result is normal, the transmission component will transfer the blank to the top of the fourth electric push rod to complete the blank hoisting, and finally discharge it from the inclined funnel to the feed of the cold header forming machine. The mechanism adopts the principle of mechanical transmission and sets up multiple blank filling spaces to independently convey single blanks in turn. During the process, the shape of each blank is detected and the blanks that do not meet the conditions are accurately screened out, thereby ensuring that the blanks conveyed to the cold header forming machine strictly meet the preset conditions.

[0024] according to Figure 3 and Figure 4 As shown, a group of first metal support frames 205 are fixedly installed at the bottom of the assembly tray 1, and the number of a group of first metal support frames 205 is equal to the hollow sleeve 202, and a first mounting sleeve 206 is fixedly installed inside each first metal support frame 205, and a first electric push rod 207 is fixedly inserted into the inner surface wall of each first mounting sleeve 206, and an external baffle 208 is fixedly sleeved on the shaft end of each first electric push rod 207, and each external baffle 208 is movably placed inside a corresponding wiring shield 203.

By presetting the above components, when the second electric push rod 308 is turned on, it can drive the push baffle 309 to slowly enter the discharge window 305, and transfer the bottom blank to each wiring shield 203 in turn.

[0028] according to Figure 6 As shown, a circular hole is opened at the bottom of the fourth electric push rod 406, and a limiting sleeve 409 is fixedly installed on the top of the inner wall of the circular hole. The inner shaft of the fourth electric push rod 406 is movably placed inside the limiting sleeve 409. By presetting the above components, the limiting sleeve 409 can limit the swing amplitude of the inner shaft of the fourth electric push rod 406, thereby improving the stability during the lifting of the blank.

[0029] according to Figure 3 and Figure 4 As shown, a group of first connecting frames 9 are fixedly installed at the bottom of the rectangular base 5, a reducer 10 is fixedly installed between the bottoms of the group of first connecting frames 9, and the bottom of the linkage rod 8 is connected to the power output end of the reducer 10.

[0030] according to Figure 3 and Figure 4 As shown, a locking frame 11 is fixedly installed at the bottom of the reducer 10 , a servo motor 12 is fixedly installed inside the locking frame 11 , and the shaft end of the servo motor 12 is connected to the power input end of the reducer 10 .

[0031] according to Figure 5 As shown, a group of second connecting frames 14 are welded to the outer wall of each bracket 13, and an annular storage cover 15 is fixedly sleeved between the outer walls of the two groups of second connecting frames 14. The discharge end of each wiring shield 203 is aligned with the opening of the annular storage cover 15. By presetting the above components, when the billets that do not meet the conditions fall downward under the action of gravity, they are collected by the annular storage cover 15.

[0032] according to Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, a group of outer open ring grooves 201 are opened on the side of the assembly pallet 1, the outer wall of the second load-bearing plate 401 is fixedly inserted into the interior of a corresponding bracket 13, and a bottom bracket 16 is fixedly sleeved between the outer walls of the two brackets 13 to determine the connection relationship between the outer open ring groove 201 and the assembly pallet 1, as well as the connection relationship between the second load-bearing plate 401 and the bracket 13.

[0033] The effect achieved by the entire mechanism is as follows: first, the equipment is moved to the designated working area, and the bottom of the bottom bracket 16 is fully in contact with the ground. At this time, the discharge end of the inclined funnel 411 is fully connected with the feed end of the cold header forming machine, and the pre-conveyed blanks are sequentially placed in the storage box 304 and stacked longitudinally, and then the external line is connected to the power supply of the equipment to provide energy for multiple electrical components. When the equipment is working, the servo motor 12 is turned on, and the power generated is transmitted from the shaft end to the reducer 10. After the deceleration is completed, the speed-changed power is directly applied to the assembly tray 1 by the linkage rod 8 through the physical characteristics of the bearing 7, and the power transmission method of the servo motor 12 The rotation is intermittent, and the range of each rotation is the angle between two adjacent locking sleeves 302. Therefore, each rotation of the assembly tray 1 will have a short pause time, the purpose of which is to provide time for pushing and lifting the blanks. When each hollow sleeve 202 moves to the front of the storage box 304, it can be fully aligned with a discharge window 305, and the second electric push rod 308 is further opened to drive the push baffle 309 to move toward the inside of the discharge window 305, pushing the next blank toward the hollow sleeve 202 until the blank moves to the top of the wiring shield 203. At this time, the blank falls into the inside of the wiring shield 203 under its own gravity. The blank can fully contact with the built-in touch sensor 204. After a blank enters a wiring shield 203, the transmission component continues to work and transfers another hollow sleeve 202 to the front of the storage box 304. The blank in the previous wiring shield 203 will be detected by the touch sensor 204 in time. If there is a defect in the shape of the blank, the measured signal is quickly fed back to the equipment system, and then the corresponding first electric push rod 207 is promptly controlled to retract its inner shaft into the cavity, driving the external baffle 208 to be pulled out of the wiring shield 203. After the blank loses support, it falls freely into the annular storage cover 15 for recovery. When the measured blank meets the conditions, its signal will be quickly fed back to the equipment system. After the blank is transferred to the top of the fourth electric push rod 406, the fourth electric push rod 406 is turned on to slowly lower the height of the electromagnetic buckle 408. At the same time, the electromagnetic buckle 408 is energized. The magnetic force generated on its surface can tightly adsorb the top of the blank after contacting it, and then the original height of the electromagnetic buckle 408 is restored, and the third electric push rod 403 is turned on to retract the inner shaft, and the adsorbed blank is transferred to the top of the inclined funnel 411, and the energy supply of the electromagnetic buckle 408 is removed to release the connected blanks. The subsequent blanks gradually enter the feed of the cold heading machine under oblique angle acceleration.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
