[0012] In a preferred embodiment of the present invention, the material guide plate is composed of a C-shaped circular ring and a guide inclined plate, and a wedge-shaped block for blocking and guiding is provided at the position where the C-shaped circular ring and the guide inclined plate are connected.

[0014] By adopting the above technical solution, the present invention has the following advantages:

[0015] 1. The present invention relies on a rotating table to drive the movement of the first fixed plate. When the first fixed plate and the corresponding infrared sensor move to the same straight line, the first fixed plate will trigger the infrared sensor accordingly. After the infrared sensor is triggered, the corresponding pressure component will be automatically turned on. At this time, the cooling oil in the oil storage frame will enter the corresponding mold through the corresponding oil guide block, thereby automatically cooling and protecting the material. At the same time, the overflowed cooling oil will be automatically recovered to avoid material waste.

[0016] 2. As the material begins to undergo cold heading stamping, the material moves downward under pressure, squeezing the cooling oil in the mold, causing the cooling oil to overflow from the mold. The overflowed cooling oil will flow outward along the oil guide groove under the guidance of the guide plate, and enter the collection frame for collection as the turntable rotates. It should be noted that the cooling oil outlet is only on the left side of the mounting frame. During the stamping process, the overflowed cooling oil will stay in the oil guide groove for a period of time until the oil guide groove is connected to the outlet, and the cooling oil will be discharged.

[0017] 3. As the material moves to the left front side of the turntable after stamping, the telescopic end of the hydraulic cylinder at the corresponding position is controlled to extend upward, so that the material is pushed upward. Then the pusher assembly is controlled to move so that the stamped material moves forward and falls into the placement frame. Finally, the ultrasonic cleaner is started to clean the material.

[0018] 4. During the outflow of cooling oil, it will accumulate in the oil guide groove for a period of time because it does not move to the discharge port. After a long time, the cooling oil may condense, causing the oil guide groove to be blocked. When the oil guide groove is found to be blocked and the cooling oil cannot be discharged normally, it is necessary to control the rotation of the rotating disk so that the first rotating shaft drives the corresponding bevel gear to rotate, and then the second rotating shaft drives the universal joint to rotate. At this time, the adsorption roller in the anti-accumulation component will start to rotate to process the oil outlet of the oil guide groove. At the same time, the scraper will squeeze the adsorption roller to prevent the accumulation of cooling oil on the adsorption roller and affect the rotation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The following further describes the technical solution with reference to specific embodiments. It should be noted that terms such as "up," "down," "left," and "right" used herein to indicate directions refer only to the positions of the structures depicted in the corresponding drawings. Component numbers, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connected" and "coupled" in this application, unless otherwise specified, include both direct and indirect connections (couplings).

[0033] Example 1

[0034] A cold heading device for fastener production, such as Figure 1-Figure 3 As shown, it includes a mounting frame 1, the top of the mounting frame 1 is rotatably connected to a rotating table 2, a hydraulic cylinder 3 is installed on the rotating table 2, the telescopic end of the hydraulic cylinder 3 is slidably connected to the rotating table 2, and the telescopic end of the hydraulic cylinder 3 extends upward to push out the stamped material, a cold heading component 4 is installed on the mounting frame 1, the cold heading component 4 is used to stamp the material, a circular first spur gear 5 is connected to the outer side of the rotating table 2, a drive motor 6 is connected to the upper rear side of the mounting frame 1, the output shaft of the drive motor 6 is set to face upward, and a second spur gear 7 is connected to the output shaft of the drive motor 6, the first spur gear 5 and the second spur gear 7 are meshed with each other, and also includes: a cooling oil injection mechanism 8, the cooling oil injection mechanism 8 is set on the mounting frame 1, and the cooling oil injection mechanism 8 is used to cool the material during stamping and forming; a recovery mechanism 9, the recovery mechanism 9 is set on the rotating table 2 and the mounting frame 1, and the recovery mechanism 9 is used to recover the overflowed cooling oil.

[0035] It should be noted that, first, the material that needs to be cold-forging is placed in the cylindrical mold on the turntable 2, and then the output shaft of the drive motor 6 is controlled to drive the second spur gear 7 to rotate, so that the first spur gear 5 rotates. The rotation of the first spur gear 5 will drive the turntable 2 to rotate, and then the cold-forging component 4 is used to continuously punch the material in the turntable 2 so that the material is finally formed. During the punching process, the cooling oil injection mechanism 8 is used to continuously inject cooling oil into the turntable 2 to prevent the material from overheating. With each downward punching of the cold-forging component 4, the material will be squeezed downward, thereby squeezing out the cooling oil in the turntable 2. At this time, the extruded cooling oil is recovered by the recovery mechanism 9 to avoid material waste.

[0036] like Figure 1 and Figure 4As shown, the cooling oil filling mechanism 8 includes an oil storage frame 81, and four oil storage frames 81 are connected to the outside of the mounting frame 1. The oil storage frame 81 is used to store cooling oil. A pressure component 82 is installed on the top of the oil storage frame 81. The pressure component 82 is used to apply pressure to the oil storage frame 81. Four oil guide blocks 83 are connected to the top of the mounting frame 1 by bolts. Oil pipelines are connected between the oil guide blocks 83 and adjacent oil storage frames 81. Infrared sensors 84 are connected to the oil storage frames 81. A first fixed plate 85 is connected to the rotating table 2. The first fixed plate 85 is used to trigger the infrared sensor 84. The infrared sensor 84 is electrically connected to the pressure component 82.

[0037] It should be noted that as the turntable 2 starts to rotate, the material will move along with the turntable 2, and the first fixed plate 85 will also start to move synchronously. When the first fixed plate 85 and the corresponding infrared sensor 84 move to the same straight line, the first fixed plate 85 will trigger the infrared sensor 84 accordingly. After the infrared sensor 84 is triggered, the corresponding pressure component 82 will be automatically turned on, thereby increasing the pressure in the corresponding oil storage frame 81. At this time, the cooling oil in the oil storage frame 81 will enter the corresponding mold through the corresponding oil guide block 83, thereby cooling and protecting the material.

[0038] like Figure 1 、 Figure 5 and Figure 6 As shown, the recovery mechanism 9 includes a guide plate 91. Six guide plates 91 are installed on the rotating table 2. The guide plate 91 consists of a C-shaped ring and a guide inclined plate. The position where the C-shaped ring is connected to the guide inclined plate is provided with a wedge block for blocking and guiding. A second fixed plate 92 is connected to the left side of the mounting frame 1. A collection frame 93 for collecting cooling oil is installed on the second fixed plate 92. An oil guide groove 94 is opened on the rotating table 2. The guide plate 91 is slidably connected to the corresponding oil guide groove 94.

[0039] It should be noted that as the material begins to undergo cold heading and stamping, the material moves downward under pressure, squeezing the cooling oil in the mold, causing the cooling oil to overflow from the mold. The overflowed cooling oil will flow outward along the oil guide groove 94 under the guidance of the guide plate 91, and enter the collection frame 93 for collection as the turntable 2 rotates subsequently. It should be noted that the mounting frame 1 only has a cooling oil outlet on the left side. During the stamping process, the overflowed cooling oil will stay in the oil guide groove 94 for a period of time until the oil guide groove 94 is connected to the outlet, and the cooling oil will be discharged.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 and Figure 7As shown, a cleaning mechanism 10 is also included. The cleaning mechanism 10 includes a third fixed plate 101. The third fixed plate 101 is provided on the mounting frame 1. A pushing assembly 102 for automatically pushing out the material is provided on the front side of the third fixed plate 101. The front side of the pushing assembly 102 is provided with a C-shaped limit frame for ensuring that the material can be pushed out stably. The front side of the mounting frame 1 is connected to a placement frame 103 for collecting the material, and an ultrasonic generator 104 for cleaning the material is installed on the placement frame 103.

[0042] It should be noted that, as the material is stamped and moves to the left front side of the turntable 2, the telescopic end of the hydraulic cylinder 3 at the corresponding position is controlled to extend upward, so that the material is pushed upward, and then the pushing assembly 102 is controlled to move, so that the material after stamping moves forward and falls into the placement frame 103, and finally the ultrasonic cleaner is started to clean the material.

[0043] like Figure 1 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the anti-accumulation mechanism 11 is also included. The anti-accumulation mechanism 11 includes a mounting seat 111. The mounting seat 111 is connected to the left front side of the mounting frame 1. The mounting seat 111 is rotatably connected to a first rotating shaft 113. The bottom of the first rotating shaft 113 is connected to a rotating disk 112. The front side of the mounting frame 1 is connected to a mounting frame 119 by bolts. The first rotating shaft 113 is rotatably connected to the mounting frame 119. The second rotating shaft 115 is rotatably connected to the mounting frame 119. The shafts 113 are connected to bevel gears 114, which are meshed with each other. The second rotating shaft 115 is connected to a universal joint 116, and the universal joint 116 is rotatably connected to an anti-accumulation component 117 for preventing the discharge port on the mounting frame 1 from being blocked. The anti-accumulation component 117 is rotatably connected to an adsorption roller, and a scraper 118 is connected between the mounting frame 1 and the mounting frame 119. The scraper 118 is used to extrude the adsorption roller on the anti-accumulation component 117.

[0044] It should be noted that, in the process of cooling oil outflow, it will accumulate in the oil guide groove 94 for a period of time because it does not move to the discharge port. After a long time, the cooling oil may condense, causing the oil guide groove 94 to be blocked. When it is found that the oil guide groove 94 is blocked and the cooling oil cannot be discharged normally, it is necessary to control the rotation of the rotating disk 112, so that the first rotating shaft 113 drives the corresponding bevel gear 114 to rotate, and then the second rotating shaft 115 drives the universal joint 116 to rotate. At this time, the adsorption roller in the anti-accumulation component 117 will start to rotate to process the oil outlet of the oil guide groove 94. At the same time, the scraper 118 will squeeze the adsorption roller to prevent the cooling oil from accumulating on the adsorption roller and affecting the rotation.

[0045] like Figure 1 and Figure 12 As shown, a filter frame 12 is also included. The filter frame 12 for carrying materials is clamped in the placement frame 103. The filter frame 12 can separate the cleaned impurities.

[0046] like Figure 1 and Figure 12 As shown, a material guide pipe 13 is also included. The front side of the mounting frame 1 is connected to the material guide pipe 13 for easy placement of materials.

[0047] While the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that numerous other embodiments can be devised without departing from the scope of the invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
