Description

Technical Field

[0001] The present application relates to the technical field of cold heading machines, and in particular to a cold heading forming machine for nut production. Background Art

[0002] Cold heading machine is a forging forming equipment that thickens the top of bars or wires at room temperature. It is specially used for mass production of fasteners such as nuts and bolts. The cold heading process has higher productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. In the working process of the cold heading machine, the generation of metal iron filings is inevitable. If these iron filings are not removed in time, they will seriously affect the recycling efficiency of the coolant and the quality of the product. Traditional filtering devices are divided into two types: horizontal placement of the filter screen and vertical placement. However, when these two methods are used, more iron filings will gradually accumulate on the filter screen, thereby affecting the filtering effect. Not only that, a certain amount of coolant will remain in the accumulated iron filings, which not only affects the circulation efficiency of the coolant, but also the long-term contact between the iron filings and the coolant will cause deterioration and odor, affecting the subsequent cleaning of the iron filings.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0038] like Figure 1-Figure 14 As shown, a cold heading forming machine for nut production proposed in one embodiment of the present application includes a casing 1, a processing assembly 2 is installed in the casing 1, the casing 1 is the outer shell of the cold heading machine, and the processing assembly 2 is the ejection assembly, the material changing assembly, the oil delivery assembly and the stamping assembly in the existing cold heading machine, and also includes:

[0039] The separation mechanism 3 includes a collection box 301 installed in the housing 1. The top and one side of the collection box 301 are open. The housing 1 is provided with a flow slot 302. The flow slot 302 is located at the top opening of the collection box 301. Specifically, the flow slot 302 is located below the processing assembly 2. A separation plate 303 is elastically slidably inserted horizontally at the opening of one side of the collection box 301.

[0040] The extrusion mechanism 4 includes a driving frame 401 horizontally slidably mounted on the collection box 301, the driving frame 401 is equipped with an extrusion plate 402 located in the collection box 301, and the collection box 301 is equipped with a driving member for driving the driving frame 401 to move; the driving member can be an existing multi-stage hydraulic telescopic rod. When the cold heading machine is working, the coolant sprayed by the oil delivery assembly will flow from the circulation groove 302 into the collection box 301, and the coolant at this time carries a certain amount of iron filings.

[0041] The oil storage mechanism 5 includes an oil storage chamber 501 provided on the housing 1. The oil delivery pipeline in the oil delivery assembly is connected to the oil storage chamber 501. The oil delivery pipeline is pumped through the pump body. The oil storage chamber 501 is used to connect with the oil delivery assembly of the cold heading machine. When the extrusion plate 402 squeezes the separation plate 303, the extruded coolant passes through the separation plate 303 and enters the oil storage chamber 501. That is to say, when the coolant enters the collection box 301, the extrusion plate 402 is moved by the driving member. As the extrusion plate 402 moves, the extrusion plate 402 pushes The coolant in the collection box 301 moves, and as the extrusion plate 402 moves, the extrusion plate 402 moves toward the separation plate 303. At this time, the iron filings in the collection box 301 are squeezed by the extrusion plate 402 and the separation plate 303, and the coolant in the collection box 301 passes through the separation plate 303 and flows into the oil storage chamber 501. The iron filings in the collection box 301 are squeezed by the extrusion plate 402 and the separation plate 303, thereby squeezing the iron filings in the collection box 301, thereby reducing the coolant contained in the iron filings;

[0042] A conveying mechanism 6 and a collecting box 7 are provided on the casing 1. The conveying mechanism 6 is installed on the casing 1. The iron filings in the collecting box 301 are sent to the collecting box 7 through the conveying mechanism 6. The iron filings after extrusion are transported to the collecting box 7 through the conveying mechanism 6, which is convenient for subsequent centralized processing of the iron filings and more convenient to use. Compared with the prior art, the present application controls the extrusion plate 402 to extrude the iron filings, thereby reducing the coolant remaining in the iron filings, and transports the iron filings to the collecting box 7 through the conveying mechanism 6, which can not only prevent the iron filings from being in contact with the coolant for a long time and causing deterioration and odor, but also facilitate the subsequent cleaning of the iron filings.

[0043] like Figure 4 and Figure 5 As shown, in some embodiments, one side of the collection box 301 is symmetrically provided with two sliding grooves 8, and a spring telescopic rod 9 is installed in the sliding groove 8. One side of the separation plate 303 is symmetrically constructed with two connecting plates 10, which are respectively inserted into the two sliding grooves 8 and connected to the free ends of the spring telescopic rod 9. A delayed reset component 11 is installed on the collection box 301. When the separation plate 303 moves to the maximum limit position of the spring telescopic rod 9 and the extrusion plate 402 does not contact the separation plate 303, the delayed reset component 11 is used to make the separation plate 303 move and reset at a regular time. That is to say, when the extrusion plate 402 moves in the direction of the separation plate 303, the pushed iron filings will contact the separation plate 303. As the extrusion plate 402 continues to move, the separation plate 303 will move. At this time, the spring in the spring telescopic rod 9 will be stretched. When the separation plate 303 is squeezed by the plate 402 When the pressure moves to a certain distance, a gap will be left between the separation plate 303 and the collection box 301. At this time, the iron filings are located between the separation plate 303 and the extrusion plate 402, and the coolant seeping from the extruded iron filings will flow into the oil storage chamber 501. After the separation plate 303 moves to the maximum limit position, the extrusion plate 402 moves in the opposite direction, so that the extrusion plate 402 moves into the collection box 301. At this time, the delayed reset component 11 can prevent the separation plate 303 from being quickly reset due to the spring telescopic rod 9. Because of the reverse movement of the extrusion plate 402, the extruded iron filings will fall due to gravity, and the conveying mechanism 6 can collect the fallen iron filings. The delayed reset component 11 makes the separation plate 303 stop moving for a period of time, and then the spring telescopic rod 9 immediately resets and hits the opening on one side of the collection box 301, thereby achieving reset.

[0044] like Figure 4As shown, in some embodiments, the extrusion plate 402 includes two holding plates 4021, and a connecting rod 4022 is constructed on the holding plate 4021. The two holding plates 4021 are symmetrically rotatably mounted on the drive frame 401 through the connecting rod 4022. A switching component 12 is installed on the housing 1. When the drive frame 401 moves toward the extrusion plate 402, the two holding plates 4021 are driven to rotate until the free ends are aligned through the switching component 12. When the drive frame 401 moves to the maximum limit position, the two holding plates 4021 are driven to rotate away from each other through the switching component 12. That is to say, when the two holding plates 4021 move toward the separation plate 303, the two holding plates 4021 are rotated to The two pressing plates 4021 are matched to form an extrusion plate 402. When the two holding plates 4021 squeeze the iron filings, and as the holding plates 4021 squeeze the iron filings and push the separation plate 303, the holding plates 4021 are always in a matched state. When the separation plate 303 moves to the maximum limit position, the drive frame 401 moves away from the separation plate 303. The two holding plates 4021 can be rotated and separated by the switching component 12. When the drive frame 401 moves toward the separation plate 303 next time, the two holding plates 4021 are rotated and matched to ensure that the coolant flowing out of the circulation groove 302 can be located between the holding plates 4021 and the separation plate 303, thereby ensuring continuity during use and further improving the separation efficiency.

[0045] like Figure 4As shown, in some embodiments, the switching assembly 12 includes a first wedge plate 1201 symmetrically constructed on the collection box 301, two connecting columns 1202 are symmetrically constructed on the collection box 301, and a second wedge plate 1203 is constructed at the free end of the connecting column 1202. A rotating rod 1204 is rotatably installed on the driving frame 401, and a synchronous wheel 1205 is mounted on the rotating rod 1204 and the connecting column 1202. A transmission belt 1206 is connected between the two synchronous wheels 1205, and a forcing plate 1207 is constructed on the transmission belt 1206. The forcing plate 1207 has symmetrical openings. There are two forcing inclined surfaces 1208, which are used to contact the first wedge plate 1201 and the second wedge plate 1203 respectively. A connecting tube 1209 is installed on the collecting box 301. A plug rod 12010 is slidably inserted at one end of the connecting tube 1209. The free end of the plug rod 12010 is an isosceles trapezoid. Two trapezoidal slots 12011 are provided on the outer peripheral side of the connecting column 1202. The angle between the two trapezoidal slots 12011 on the connecting column 1202 is 90 degrees. A tightening spring 12012 is installed between the plug rod 12010 and the connecting tube 1209. When the drive frame 401 moves to When the separation plate 303 moves in the direction of the drive frame 401, one of the forcing inclined surfaces 1208 on the forcing plate 1207 will contact the first wedge plate 1201, which will force the transmission belt 1206 to move. As the transmission belt 1206 moves, the connecting column 1202 will rotate. At this time, the plug-in rod 12010 will be disengaged from the trapezoidal slot 12011 and inserted into another trapezoidal slot 12011. At this time, the plug-in rod 12010 has been rotated to 90 degrees, and the two holding plates 4021 are at the same horizontal plane. When the chips are removed and the separation plate 303 is pushed, the design of the pressing spring 12012 can keep the connecting rod 12010 inserted in the trapezoidal slot 12011 to prevent accidental rotation due to pressure when the holding plate 4021 squeezes the iron chips. When the separation plate 303 moves to the maximum limit, the forcing plate 1207 will contact the second wedge plate 1203, so that the transmission belt 1206 rotates in the opposite direction, and then the two holding plates 4021 rotate from the matched state to the separated state, so that no additional driving force is needed to drive the rotation of the holding plates 4021, which is more convenient to use.

[0046] like Figure 4 and Fig.12As shown, in some embodiments, the time-delay reset element 11 includes a convex plate 1101 symmetrically constructed on the driving frame 401, a groove 1102 is provided on the convex plate 1101, a blocking plate 1103 is slidably installed in the groove 1102, a sliding rod 1104 is horizontally inserted in the groove 1102 for sliding sliding, a compression spring 1105 is installed between the sliding rod 1104 and the inside of the convex plate 1101, the sliding rod 1104 is connected to the blocking plate 1103, a vent hole 1106 connected to the sliding groove 8 is provided on one side of the collection box 301, and a reserved groove 1107 is provided on the driving frame 401, and the reserved groove 1107 is inserted through a torsion spring. The actuator plate 1109 is rotatably mounted, and the actuator plate 1109 is fitted with one side of the reserved groove 1107. The free end of the actuator plate 1109 is located outside the reserved groove 1107. The side of the blocking plate 1103 facing the actuator plate 1109 is provided with a driving inclined surface 1108. That is to say, when the driving frame 401 moves toward the separation plate 303, the holding plate 4021 pushes the separation plate 303 to move, and the outside air will enter the vent hole 1106. When the driving frame 401 moves toward the separation plate 303, the actuator plate 1109 will contact the driving inclined surface 1108 of the blocking plate 1103, thereby driving When the frame 401 moves toward the separation plate 303, the blocking plate 1103 will not block the vent 1106. When the separation plate 303 moves to the maximum limit position, the blocking plate 1103 is just separated from the execution plate 1109. Therefore, the blocking plate 1103 at this time will be pressed against the vent 1106 by the action of the compression spring 1105, thereby preventing the outside air from entering the sliding groove 8 from the vent 1106, thereby forming a negative pressure in the sliding groove 8, and the air in the sliding groove 8 cannot be discharged, thereby overcoming the elastic pressure of the spring telescopic rod 9. When the driving frame 401 moves away from the separation plate When the driving frame 401 moves in the direction of the separation plate 303, the blocking plate 1103 will contact the execution plate 1109, thereby forcing the execution plate 1109 to rotate into the reserved groove 1107, and then when the driving frame 401 moves in the direction away from the separation plate 303, the blocking plate 1103 will always block the vent 1106 during movement, so that the separation plate 303 will not rebound and reset for a while. Only when the blocking plate 1103 is separated from the vent 1106, the gas in the sliding groove 8 will be discharged from the vent 1106, so that the separation plate 303 moves and resets, thereby realizing the delayed rebound of the separation plate 303, which is more convenient to use.

[0047] like Figure 4 and Figure 5As shown, in some embodiments, a screen frame 13 is installed obliquely at the bottom of the separation plate 303, and a conversion box 14 is installed at the lowest end of the screen frame 13. One side of the conversion box 14 is open and a screen plate 15 is installed obliquely inside. A drainage groove 16 is opened on one side of the conversion box 14, and the conversion box 14 and the oil storage chamber 501 are connected through the drainage groove 16. When the separation plate 303 is pushed, the coolant seeping from the separation plate 303 will enter the conversion box 14, and then the coolant passes through the screen plate 15 in the conversion box 14, and finally enters the oil storage chamber 501 from the drainage groove 16, and the squeezed iron filings will fall into the screen plate 15 in the conversion box 14 due to the action of gravity. Because of the inclined design of the screen plate 15, the squeezed iron filings will roll on the screen plate 15 to the conveying mechanism 6 at this time, and the iron filings will be conveyed to the collection box 7 through the conveying mechanism 6.

[0048] like Figure 2 and Figure 4 As shown, in some embodiments, the bottom surface of the oil storage chamber 501 is an inclined surface, and the conversion box 14 is constructed with a connecting box 17 located below the screen frame 13, that is, the coolant seeping from the screen frame 13 will enter the connecting box 17, and the connecting box 17 is provided with a liquid outlet groove 18. The highest point of the bottom surface of the oil storage chamber 501 is located above the liquid outlet groove 18. The design of the inclined surface of the oil storage chamber 501 can effectively introduce the coolant in the connecting box 17 into the oil storage chamber 501.

[0049] like Figure 3 and Figure 5 As shown, in some embodiments, the conveying mechanism 6 includes a connecting frame 19 installed on the back of the casing 1, and a belt conveyor 20 is obliquely installed on the connecting frame 19, and the collecting box 7 is located below the highest point of the belt conveyor 20, that is, the lowest end of the screen plate 15 is always located above the belt conveyor 20 when sliding, so that the squeezed iron chips will be conveyed to the belt conveyor 20, and then the belt conveyor 20 can effectively transport the iron chips to the collecting box 7.

[0050] like Figure 4 and Fig.14As shown, in some embodiments, the screen frame 13 is tilted and rotatably installed on the separation plate 303, the conversion box 14 is connected to the bottom end of the separation plate 303 through the connecting piece 21, a rotating disk 23 is rotatably installed on one side of the separation plate 303, and an articulated rod 24 is eccentrically rotatably installed on the rotating disk 23, and the free end of the articulated rod 24 is hinged on the screen frame 13. Specifically, the rotating disk 23 can be driven by a motor, and the motor is preset in the separation plate 303. As the rotating disk 23 rotates, the rotating disk 23 will drive the articulated rod 24 to move on the rotating rod 1204. Because the free end of the articulated rod 24 is hinged on the screen frame 13, the screen frame 13 will shake up and down rapidly during use, thereby shaking off the squeezed iron filings, and cooperating with the connecting piece 21 to further separate the coolant in the iron filings.

[0051] like Figure 4 and Fig.10 As shown, in some embodiments, the connecting member 21 includes a hinged plug plate 22 hinged at the bottom end of the screen frame 13, and the hinged plug plate 22 is vertically slidably inserted in the top of the conversion box 14. When the screen frame 13 is shaking, because the hinged plug plate 22 is vertically slidably inserted in the top of the conversion box 14, the conversion box 14 will also shake back and forth when the screen frame 13 shakes, thereby further improving the separation effect of iron chips.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
