Description

Technical Field

[0001] This utility model relates to the field of screw sleeve manufacturing technology, and in particular to a tailed screw sleeve production equipment. Background Technology

[0002] As a precision internal thread fastener reinforcement element, wire thread inserts are widely used in aerospace, automotive, precision instruments, military equipment and other fields. Especially in low-strength or easily damaged materials such as aluminum alloys, magnesium alloys, titanium alloys and composite materials, they can significantly improve the strength, wear resistance, fatigue resistance and reliability of threaded connections. Its core component - the wire thread insert body - is a spring-like structure with internal and external threads made of special stainless steel wire with high-precision rhomboid cross section.

[0003] A wire rolling device for producing wire thread inserts is disclosed in Chinese patent document CN222037556U. This device includes a base plate. Two mounting frames (I) are symmetrically fixedly installed on the upper rear side of the outer wall of the base plate. Two winding rollers are rotatably connected to opposite sides of the outer walls of the two mounting frames (I). Two mounting frames (II) are symmetrically fixedly installed on the upper end of the outer wall of the base plate, in front of the two mounting frames (I). Two hydraulic telescopic rods (I) are fixedly installed on opposite sides of the outer walls of the two mounting frames (II). This invention uses the action of two hydraulic telescopic rods (I) to bring extrusion rollers (I) and extrusion rollers (II) closer together to extrude and shape a circular cross-section wire into a rhomboid cross-section wire. The rhomboid cross-section wire produces a wire thread insert with greater internal thread friction than the circular cross-section wire, resulting in a stronger tightening effect on bolts (or screws), thus improving the quality of the produced wire thread insert. However, this wire rolling device for producing wire thread inserts has a low degree of automation and low production efficiency.

[0004] To address the shortcomings of the existing technology, providing a tail-end screw sleeve production equipment is a problem worthy of research. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of low automation and low production efficiency, and to provide a tail thread sleeve production equipment that achieves the technical effect of high-speed automatic production of wire thread sleeves and wire rolling.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A tail-end sleeve production device includes a wire rolling mill body, a wire feeding frame disposed on the wire input side of the wire rolling mill body, a support frame fixedly connected to the top center of the wire rolling mill body, a wire feeding mechanism disposed on one side of the support frame, a cutting mechanism disposed on the other side of the support frame, a winding mechanism disposed on the rear side of the cutting mechanism, a grooving mechanism disposed on the rear side of the winding mechanism, and a feeding mechanism disposed below the winding mechanism and the grooving mechanism.

[0008] The wire feeding mechanism includes a wire feeding roller group disposed on the rear side of the support frame, and a straightener disposed on the rear side of the wire feeding roller group;

[0009] The wire inlet of the straightener is aligned with the wire feeding frame, and the wire outlet of the wire feeding roller assembly is aligned with the circular hole of the support frame.

[0010] The diameter of the wire feeding groove of the wire feeding roller group and the straightener is adapted to the diameter of the steel wire used for wire rolling.

[0011] The straightener consists of two mutually perpendicular straighteners, which ensure that the steel wire is straight before winding, thus preventing the steel wire from bending and affecting the processing effect.

[0012] The cutting mechanism includes a cutting cylinder fixedly connected to a support frame, and a cutting blade fixedly connected to the output end of the cutting cylinder.

[0013] When the cutting cylinder retracts, the cutting tool is located above the support frame through hole; when the cutting cylinder extends, the cutting edge of the cutting tool is located below the support frame through hole. The reciprocating extension and retraction of the cutting cylinder can realize automatic unloading after the threaded sleeve is processed, thereby improving the production efficiency of the threaded sleeve.

[0014] The cutting mechanism is located above the feeding mechanism. By placing the cutting mechanism above the feeding mechanism, the tailed thread sleeves cut off by the cutting mechanism can fall into the feeding mechanism, thus avoiding waste caused by the feeding mechanism not catching the produced tailed thread sleeves.

[0015] The winding mechanism includes a first adjusting slide rail fixedly connected to the top of the main body of the wire rolling mill, and a winding cutter slidably connected above the first adjusting slide rail. The positional relationship between the winding cutter and the steel wire is adjusted by the first adjusting slide rail, and the winding cutter is brought into contact with the steel wire for winding processing when necessary.

[0016] The grooving mechanism includes a second adjusting slide rail fixedly connected to the top of the wire rolling mill body, an angle adjusting frame slidably connected to the second adjusting slide rail, a third adjusting slide rail rotatably connected to the angle adjusting frame, a servo motor slidably connected to the third adjusting slide rail, and a grooving drill fixedly connected to the output end of the servo motor.

[0017] The sliding directions of the second and third adjusting slide rails are perpendicular to each other. The angle adjusting frame is driven by a motor to control the angle of the third adjusting slide rail. Both the second and third adjusting slide rails are electric slide rails. The position for slotting the tailed threaded sleeve is adjusted by the second adjusting slide rail. The slotting angle of the slotting drill is adjusted by the relative rotation of the angle adjusting frame and the third adjusting slide rail. The feed and retraction of the slotting drill are controlled by the third adjusting slide rail. Thus, the tailed threaded sleeve can be automatically adjusted and slotted in multiple angles and directions as needed, improving the slotting efficiency of the device.

[0018] The feeding mechanism includes a feeding channel located inside the main body of the wire rolling mill, and a baffle rotatably connected to the bottom opening of the feeding channel. By setting the baffle at the bottom opening of the feeding channel, the feeding tailed thread sleeve is blocked and buffered, so that the tailed thread sleeve falls downward from the gap between the feeding channel and the baffle, avoiding the tailed thread sleeve from flying directly out along the inclined surface of the feeding channel, which would result in the feeding not completely entering the collecting device.

[0019] The top and bottom of the feeding channel are open, and the lower half of the feeding channel is a slope.

[0020] 1. This high-speed wire rolling mill for steel wire thread inserts has a cutting cylinder with a cutting tool installed above the through hole of the support frame. The cylinder cuts off the finished thread insert with a tail after winding, so that the finished thread insert is separated from the steel wire and the material is unloaded. The reciprocating extension and retraction of the cutting cylinder can realize the automatic unloading of the thread insert after processing, thereby improving the production efficiency of thread inserts.

[0021] 2. The high-speed wire rolling mill for steel wire thread sleeves uses a second adjusting slide rail to adjust the position of the slotting of the tailed thread sleeve. The relative rotation of the angle adjusting frame and the third adjusting slide rail adjusts the slotting angle of the slotting drill. The third adjusting slide rail controls the feed and retraction of the slotting drill, thereby realizing automatic adjustment and slotting of the tailed thread sleeve at multiple angles and directions as needed, improving the slotting efficiency of the device.

[0022] 3. The high-speed wire rolling mill for steel wire thread sleeves has a baffle at the bottom opening of the feeding channel to block and buffer the feeding of tailed thread sleeves, so that the tailed thread sleeves fall downward through the gap between the feeding channel and the baffle, avoiding the tailed thread sleeves flying directly out along the inclined surface of the feeding channel, which would result in the feeding material not completely entering the collecting device.

Detailed Implementation

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0034] like Figures 1 to 9As shown, a tail-end sleeve production equipment includes a wire rolling mill body 1 and a wire feeding frame 2 disposed on the wire input side of the wire rolling mill body 1. The equipment is characterized by further including a support frame 3 fixedly connected to the top middle of the wire rolling mill body 1, a wire feeding mechanism 4 disposed on one side of the support frame 3, a cutting mechanism 5 disposed on the other side of the support frame 3, a winding mechanism 6 disposed on the rear side of the cutting mechanism 5, a grooving mechanism 7 disposed on the rear side of the winding mechanism 6, and a feeding mechanism 8 disposed below and between the winding mechanism 6 and the grooving mechanism 7.

[0035] like Figures 1 to 3 As shown, the wire feeding mechanism 4 includes a wire feeding roller group 401 disposed on the rear side of the support frame 3, and a straightener 402 disposed on the rear side of the wire feeding roller group 401.

[0036] The wire inlet of the straightener 402 is aligned with the wire feeding frame 2, and the wire outlet of the wire feeding roller group 401 is aligned with the round hole of the support frame 3.

[0037] The diameter of the wire feeding groove of the wire feeding roller group 401 and the straightener 402 is matched with the diameter of the steel wire used for wire rolling.

[0038] like Figure 3 As shown, the straightener 402 consists of two mutually perpendicular straighteners. By setting the straightener 402 to two mutually perpendicular straighteners, it can calibrate the steel wire in both the horizontal and vertical directions, so that the steel wire is straight before winding and avoids bending of the steel wire from affecting the processing effect. Example 2

[0039] like Figures 5 to 6 As shown, the cutting mechanism 5 includes a cutting cylinder 501 fixedly connected to the support frame 3, and a cutting blade 502 fixedly connected to the output end of the cutting cylinder 501.

[0040] When the cutting cylinder 501 retracts, the cutting tool 502 is located above the through hole of the support frame 3. When the cutting cylinder 501 extends, the cutting edge of the cutting tool 502 is located below the through hole of the support frame 3. By setting the cutting cylinder 501 with the cutting tool 502 above the through hole of the support frame 3, the finished threaded sleeve with tail is cut off, so that the finished threaded sleeve is separated from the steel wire and the material is unloaded. The reciprocating extension and retraction of the cutting cylinder 501 can realize the automatic unloading of the threaded sleeve after processing, thereby improving the production efficiency of the threaded sleeve.

[0041] like Figure 6 As shown, the cutting mechanism 5 is located above the feeding mechanism 8. By setting the cutting mechanism 5 above the feeding mechanism 8, the tailed thread sleeves cut off by the cutting mechanism 5 can fall into the feeding mechanism 8, thus avoiding the situation where the feeding mechanism 8 fails to receive the produced tailed thread sleeves, resulting in waste. Example 3

[0042] like Figures 4 to 6 As shown, the winding mechanism 6 includes a first adjusting slide rail 601 fixedly connected to the top of the main body 1 of the wire rolling mill, and a winding cutter 602 slidably connected above the first adjusting slide rail 601. The positional relationship between the winding cutter 602 and the steel wire is adjusted by the first adjusting slide rail 601, and the winding cutter 602 is brought into contact with the steel wire for winding processing when necessary.

[0043] like Figures 5 to 9 As shown, the grooving mechanism 7 includes a second adjusting slide rail 701 fixedly connected to the top of the wire rolling mill body 1, an angle adjusting frame 702 slidably connected to the second adjusting slide rail 701, a third adjusting slide rail 703 rotatably connected to the angle adjusting frame 702, a servo motor 704 slidably connected to the third adjusting slide rail 703, and a grooving drill 705 fixedly connected to the output end of the servo motor 704.

[0044] like Figures 5 to 9 As shown, the sliding directions of the second adjusting slide rail 701 and the third adjusting slide rail 703 are perpendicular to each other. The angle adjusting frame 702 is driven by a motor to control the angle of the third adjusting slide rail 703. Both the second adjusting slide rail 701 and the third adjusting slide rail 703 are electric slide rails. The position of the grooving of the tailed threaded sleeve is adjusted by the second adjusting slide rail 701. The grooving angle of the grooving tool 705 is adjusted by the relative rotation of the angle adjusting frame 702 and the third adjusting slide rail 703. The feed and retraction of the grooving tool 705 are controlled by the third adjusting slide rail 703. Thus, the grooving of the tailed threaded sleeve can be automatically adjusted and grooved in multiple angles and directions as needed, thereby improving the grooving efficiency of the device. Example 4

[0045] like Figures 5 to 9 As shown, the feeding mechanism 8 includes a feeding channel 801 located inside the main body 1 of the wire rolling mill, and a baffle 802 rotatably connected to the bottom opening of the feeding channel 801. By setting the baffle 802 at the bottom opening of the feeding channel 801, the feeding tailed threaded sleeve is blocked and buffered, so that the tailed threaded sleeve falls downward from the gap between the feeding channel 801 and the baffle 802, avoiding the tailed threaded sleeve flying directly out along the inclined surface of the feeding channel 801, which would cause the feeding to not completely enter the collecting device. Under the action of its own weight, the baffle 802 is normally closed to the bottom of the feeding channel 801. When the baffle 802 is subjected to the force of the feeding tailed threaded sleeve, it rotates outward and opens, so that the tailed threaded sleeve falls vertically to complete the feeding.

[0046] like Figures 8 to 9 As shown, the top and bottom of the feeding channel 801 are open, and the lower half of the feeding channel 801 is a slope.

[0047] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
