Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, specifically a cold heading forming equipment for nut production with a chip removal structure. Background Technology

[0002] In the field of nut production, cold heading has become one of the mainstream processing methods due to its advantages such as high efficiency, energy saving, high material utilization and stable forming quality. Cold heading equipment applies pressure to the metal blank through a mold, causing it to plastically deform at room temperature to form the nut prototype. Inevitably, impurities such as iron filings and metal shavings will be generated during this process.

[0003] A search revealed that patent publication number CN222001776U discloses a highly automated nut cold heading machine, including a worktable. The bottom surface of the worktable is equipped with a material handling mechanism, which includes a first fixed plate and a second fixed plate fixed to the bottom surface of the worktable. Two servo motors are fixedly connected to the right side of the second fixed plate. The output shafts of the servo motors are fixedly connected to threaded rods. A threaded ring is threaded onto the outer surface of the threaded rod, and a movable plate is fixedly connected to the outer surface of the threaded ring. A support plate is fixedly connected to the upper surface of the movable plate. A placement groove is formed on the upper surface of the worktable, and a stationary mold is placed inside the groove. A through hole is formed in the inner bottom wall of the placement groove. This technical solution solves the problem in existing technologies where, after the nut cold heading machine has completed the stamping of the raw material, the finished product still needs to be manually removed, thus increasing the labor intensity of the workers.

[0004] In practical use, the above-mentioned technical solution requires frequent starting of the linear motor module to automatically unload the cold-forged nuts. However, frequent starting of the linear motor module to achieve automatic unloading of the cold-forged nuts can affect the processing efficiency of the nuts. Furthermore, existing cold-forging equipment for nut production generates a certain amount of iron filings that adhere to the mold surface during the actual cold-forging process. If the iron filings are not removed in time, they may cause scratches on the nut surface and deviations in dimensional accuracy. Currently, manual periodic shutdowns are usually used to clean the iron filings, which consumes a lot of time and labor costs. Therefore, a cold-forging equipment for nut production with an iron filings cleaning structure is designed. Utility Model Content

[0011] The rotating mold is set on the top of the support plate. The surface of the rotating mold has four cold heading grooves arranged in a ring array.

[0012] Preferably, the drive assembly is provided with a stepper motor, which is mounted on the other side of the top of the base.

[0016] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0017] 1. In this utility model, through a series of coordinated structural arrangements, when the operator performs cold heading on a nut, an external robotic arm places the nut into one of the cold heading slots on the rotary mold. Upon starting the equipment, the stepper motor on the drive assembly rotates the rotary mold at a certain angle. Once the cold heading slot containing the nut is directly below the cold heading head, the hydraulic telescopic rod on the cold heading assembly activates and drives the cold heading head to perform cold heading on the nut in the cold heading slot. While the nut is being cold-headed, the external robotic arm continues to place another nut into one of the cold heading slots on the rotary mold. After the nut is cold-headed, the hydraulic... After the telescopic rod moves to its initial position, the stepper motor on the drive assembly drives the rotary mold to rotate a certain angle again. When the cold heading forming assembly performs cold heading operation on another nut, the cold heading forming assembly will drive the piston rod and rubber piston on the cleaning assembly to perform piston movement inside the piston cylinder. When the rubber piston performs piston movement inside the piston cylinder, it will cause the exhaust nozzle on the cleaning assembly to exhaust air. The exhaust air from the exhaust nozzle can blow the iron filings generated during the cold heading process of the nut into the iron filings collection tank for collection. Thus, this utility model can automatically clean and collect the iron filings generated during the cold heading process of the nut, reducing the labor intensity of workers and improving processing efficiency.

[0018] 2. In this utility model, through a series of coordinated structural arrangements, after the cleaning component blows the iron filings generated during the cold heading process of the nut into the iron filings collection trough, when the next nut is cold-headed, the stepper motor on the drive component continues to drive the rotating mold to rotate at a certain angle. The cold heading groove with the cold-headed nut rotates to directly above the discharge port. At this time, the cold-headed nut in the cold heading groove falls from the discharge port into the nut cold heading collection trough for collection, thereby realizing the automatic collection of the cold-headed nut and improving efficiency.

[0019] 3. In this utility model, through a series of coordinated structural arrangements, when the cold heading head on the cold heading forming assembly performs cold heading on the nut in the cold heading groove, one end of the ejector pin on the cold heading forming assembly will move to another cold heading groove. When the nut in the other cold heading groove is stuck in the cold heading groove, the ejector pin will push the nut out of the cold heading groove, thereby avoiding the situation where the nut after cold heading is stuck in the cold heading groove, and further improving the processing efficiency.

[0041] Guide columns are installed on both sides of the upper surface of the lifting plate 120, and the top of the guide column passes through the guide sleeve on the top of the mounting frame 150. The guide column and guide sleeve can limit and guide the movement of the lifting plate 120, thereby enhancing the stability of the lifting plate 120 during movement.

[0042] A support frame 430 is provided on the support assembly 400. The support frame 430 is installed at the front end of the top of the base 600.

The nut cold heading forming collection trough is installed on one side of the top of the base 600. The shock absorber 420 plays a buffering role when the cold heading head 130 performs cold heading forming operation on the nut in the cold heading trough 310, reducing the instantaneous impact force on the support plate 410.

[0043] The rotary mold 300 is set on the top of the support plate 410. The surface of the rotary mold 300 has four cold heading grooves 310 arranged in a ring array. A through hole 320 is opened at the center of the surface of the rotary mold 300. A limiting groove 330 arranged in a ring array is provided on the circumferential inner wall of the through hole 320.

[0044] A stepper motor 510 is provided on the drive assembly 500, and the stepper motor 510 is mounted on the other side of the top of the base 600. A drive pulley 520 is mounted on the output shaft of the stepper motor 510. The drive pulley 520 is connected to the driven pulley 530 through a transmission belt. The driven pulley 530 is located on the outer wall of the rotating shaft 540. The bottom end of the rotating shaft 540 is mounted in a bearing housing, and the bearing housing is mounted on the top of the base 600.

[0045] The top end of the rotating shaft 540 passes through the bearing at the center of the support plate 410 and the through hole 320 on the rotating mold 300, and is connected to the fastening sleeve. The fastening sleeve is located on the top of the rotating mold 300, and the fastening sleeve and the rotating shaft 540 are fixedly connected by fastening bolts. A ring-shaped array of limiting protrusions 541 is provided above the circumferential outer wall of the rotating shaft 540.

The outer wall of the limiting protrusions 541 and the groove wall of the limiting groove 330 are in clearance fit. The outer wall of 40 and the hole wall of the through hole 320 are in clearance fit. When the stepper motor 510 starts, it will drive the drive pulley 520 to rotate at a certain angle. The rotation of the drive pulley 520 at a certain angle will drive the driven pulley 530 to rotate at a certain angle through the transmission belt. The rotation of the driven pulley 530 at a certain angle will drive the rotating shaft 540 to rotate at a certain angle. The rotation of the rotating shaft 540 at a certain angle will drive the rotating mold 300 to rotate at a certain angle.

[0046] The cleaning assembly 200 is provided with a piston cylinder 230, which is installed at the top of the mounting base 620. A rubber piston is provided inside the piston cylinder 230, and the rubber piston is installed at one end of the piston rod 240. The other end of the piston rod 240 is installed at the bottom rear end of the lifting plate 120. When the lifting plate 120 moves linearly in the Y-axis direction, the rubber piston on the piston rod 240 will move in the piston cylinder 230.

[0047] The piston cylinder 230 has an intake pipe 231 and an exhaust pipe 232 on its two sides below the circumferential outer wall. Both the intake pipe 231 and the exhaust pipe 232 are equipped with one-way valves. The exhaust pipe 232 is connected to the exhaust nozzle 220 through a delivery pipe. The exhaust nozzle 220 is located at one end of the connecting rod 210. The other end of the connecting rod 210 is installed on the upper surface of the support plate 410. Since both the intake pipe 231 and the exhaust pipe 232 are equipped with one-way valves, the intake pipe 231 can only allow air to enter, and the exhaust pipe 232 can only allow air to exit.

[0048] Working Principle: When in use, an external power supply is connected. When the operator performs cold heading on a nut, an external robotic arm places the nut into one of the cold heading slots 310 on the rotary mold 300. Starting the equipment activates the stepper motor 510 on the drive assembly 500, causing the rotary mold 300 to rotate at a certain angle. Once the cold heading slot 310 containing the nut is directly below the cold heading head 130, the hydraulic telescopic rod 110 on the cold heading assembly 100 activates, driving the cold heading head 130 to perform cold heading on the nut in the cold heading slot 310. While the nut is being cold-headed, the external robotic arm continues to place another nut... After the nut is cold-forged into one of the cold-forging slots 310 on the rotary mold 300, the hydraulic telescopic rod 110 moves to its initial position. The stepper motor 510 on the drive assembly 500 then rotates the rotary mold 300 by a certain angle. When the cold-forging assembly 100 performs cold-forging on another nut, it drives the piston rod 240 and rubber piston on the cleaning assembly 200 to move within the piston cylinder 230. This piston movement causes the vent nozzle 220 on the cleaning assembly 200 to release air. The vent nozzle 220 releases air during the cold-forging process of the nut. The generated iron filings are blown into the iron filings collection trough 630 for collection. This invention automatically cleans and collects the iron filings generated during the cold heading process of nuts, reducing the labor intensity of workers and improving processing efficiency. After the cleaning component 200 blows the iron filings generated during the cold heading process of the nut into the iron filings collection trough 630, when performing cold heading operation on a subsequent nut, the stepper motor 510 on the drive component 500 continues to drive the rotating mold 300 to rotate at a certain angle. The cold heading groove 310 with the cold-headed nut rotates to directly above the discharge port 411. At this time, the cold heading nut in the cold heading groove 310... After forming, the nut falls from the discharge port 411 into the nut cold heading forming collection tank for collection, thereby realizing automatic collection of the cold-headed nut and improving efficiency. When the cold heading head 130 on the cold heading forming assembly 100 cold-heads the nut in the cold heading groove 310, one end of the ejector column 140 on the cold heading forming assembly 100 will move to another cold heading groove 310. When the nut in the other cold heading groove 310 is stuck in the cold heading groove 310, the ejector column 140 will push the nut out of the cold heading groove 310, thereby avoiding the situation where the cold-headed nut is stuck in the cold heading groove 310 and further improving processing efficiency.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
