Description

Technical Field

[0001] This utility model belongs to the field of heading machine technology, specifically relating to a cutting and feeding assembly. Background Technology

[0002] Screw heading machines are a type of cold forging equipment, designed for producing screw heads using a single die and two punches. Their working principle involves straightening, feeding, cutting, and inserting the wire into the main die; the first punch for initial forging; and the second punch for removing the finished blank. The entire process is completed in one continuous operation, with a capacity of approximately 200 screws per minute, making it a relatively advanced piece of equipment. It can forge various metal materials, including ordinary steel, carbon steel, stainless steel, copper, aluminum, and alloy steel, for products such as self-tapping screws, electrical screws, miniature screws, internal and external hex bolts, self-drilling screws, and fiberboard screws.

[0003] Chinese patent document with application number CN202223034424.9 discloses an adjustable screw heading machine, including a base, a scissor drive device fixed to the base, a linkage assembly with one end connected to the scissor drive device, and a drive mechanism connecting the other end of the linkage assembly and connected to the base.

[0004] Further research by the applicant revealed that although the technical solution can feed the wire into one side of the main mold through the scissor assembly and into the die hole under the action of the punch, in order to ensure the continuity of processing, after the punching process is completed, the stamped bolts need to be cut off to remove them from the main mold in order to complete the closed-loop operation of the cyclic processing. However, the feeding and cutting steps of the existing heading machine are two relatively independent mechanical structures, which cannot guarantee that the two match the cycle frequency, and the reliability needs to be improved. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A cutting and feeding assembly, comprising:

[0007] The cutting slide plate has an arc-shaped guide groove on its upper end surface along the length direction;

[0008] The feeding slide plate has a through hole, in which a reversing slide shaft that can cooperate with the arc-shaped guide groove is installed. One end of the feeding slide plate is connected to a feeding head, and the other end is hinged to a cutting mechanism located on the upper part of the feeding head. When the cutting mechanism is in working state, the cutting blade in the cutting mechanism is vertically arranged on the outside of the feeding head.

[0009] As the cutting slide plate is driven by an external transmission component to move longitudinally back and forth, the feeding slide plate and the cutting mechanism move laterally back and forth through the relative sliding engagement between the reversing slide shaft and the arc-shaped guide groove.

[0010] Furthermore, the cutting slide plate has pairs of protrusions and concave blocks, and the gap between the protrusions and concave blocks forms the arc-shaped guide groove.

[0011] Furthermore, the tail of the cutting slide is connected to a hinge rod, which is connected to the transmission assembly.

[0012] Furthermore, the cutting mechanism also includes a cutting blade holder, and the cutting blade body is detachably connected to the head of the cutting blade holder.

[0013] Furthermore, a hinge seat is provided at the end of the cutting slide away from the feeding head, and the cutting blade holder is connected to the hinge seat.

[0014] Furthermore, it also includes a limiting seat that cooperates with the cutting blade holder.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] By using a feeding slide plate that is matched with the cutting slide plate, the cutting mechanism is connected to the feeding head. Under the action of the reversing slide shaft and the arc-shaped guide groove, the longitudinal movement of the cutting slide plate is synchronously converted into the lateral reciprocating movement. This enables the feeding head to feed the wire towards the main mold side. At the same time, the bolt that has been stamped is cut off by the cutting conductor and falls from the main mold and is collected. This method combines the feeding and cutting of the wire into a whole, achieving linkage in mechanical movement, and ensuring its operation frequency and reliability. Attached Figure Description

Therefore, the terms describing positional relationships in the drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0030] like Figure 1 - Figure 9 As shown, a cutting and feeding assembly of this utility model includes a cutting slide plate 1 and a feeding slide plate 2;

[0031] Among them, an arc-shaped guide groove 100 is provided on the upper end surface of the cutting slide plate 1 along the length direction;

[0032] A through hole 20 is provided on the feeding slide plate 2. A reversing slide shaft 21 that can cooperate with the arc-shaped guide groove 100 is provided in the through hole 20. One end of the feeding slide plate 2 is connected to the feeding head 22, and the other end is hinged to the cutting mechanism provided on the upper part of the feeding head 22. When the cutting mechanism is in working state, the cutting blade 30 in the cutting mechanism is vertically arranged on the outside of the feeding head 22.

[0033] As the cutting slide plate 1 is driven by the external transmission component 9 to move longitudinally back and forth, the feeding slide plate 2 and the cutting mechanism move laterally back and forth through the relative sliding engagement between the reversing slide shaft 21 and the arc-shaped guide groove 100.

[0034] By using a feeding slide plate 2 that is fitted on the cutting slide plate 1, the cutting mechanism is connected to the feeding head 22. Under the action of the reversing slide shaft 21 and the arc-shaped guide groove 100, the longitudinal movement of the cutting slide plate 1 is synchronously converted into the lateral reciprocating movement. This enables the feeding head 22 to feed the wire towards the main mold 60. At the same time, the bolt that has been stamped is cut off by the cutting conductor and falls from the main mold 60 and is collected. This method combines the feeding and cutting of the wire into a whole, achieving linkage in mechanical movement, and ensuring its operation frequency and reliability.

[0035] The cutting slide plate 1 has a pair of protrusions 10 and concave blocks 11, and there is a gap between the protrusions 10 and concave blocks 11 to form an arc-shaped guide groove 100. The protrusions 10 and concave blocks 11 are detachable.

[0036] In addition, the tail of the cutting slide plate 1 is connected to a hinge rod, which is connected to the transmission assembly 9 via the hinge rod.

[0037] The cutting mechanism also includes a cutting blade holder 31, with the cutting blade body 30 detachably connected to the head of the cutting blade holder 31. A hinge seat 32 is provided at the end of the cutting slide plate 1 away from the feeding head 22, and the cutting blade holder 31 is connected to the hinge seat 32.

[0038] Since the cutting blade holder 31 is hinged to the hinge seat 32, when it is necessary to replace the punch and adjust the wire, the operator can use his hand to pry the cutting blade holder 31 up and flip it over. After completing the maintenance and preparation, the cutting blade holder 31 is restored.

[0039] In addition, the upper part of the upper body 4 is also connected to a limiting seat 33 that cooperates with the cutting knife holder 31. After the cutting knife holder 31 is lowered, the cutting knife holder 31 is in the limiting seat 33. The function of the limiting seat 33 is to prevent the cutting knife holder 31 and the cutting knife body 30 from shaking when interacting with the wire.

[0040] Specifically, the front end of the feed head is U-shaped. During the lateral movement of the feed head, the wire is positioned within the U-shaped structure and is pushed along it. The through-hole is racetrack-shaped.

[0041] This utility model also discloses a heading machine, which includes an upper body 4, a lower base 5, a cutting and feeding assembly A, a main die 60, a punch 61, a transmission assembly 9, and a sliding and pushing assembly 7 that drives the punch 61 to move closer to or away from the main die 60. Among them, the cutting slide plate 1 in the cutting and feeding assembly A is connected to the side of the upper body 4 through a slide block 14.

[0042] A lifting assembly 8 is connected in the lower base 5. The lifting assembly 8 forces the punch 61 to move up and down reciprocally on the side of the sliding assembly 7. The purpose of setting the lifting assembly 8 is to realize one die and two punches. After the first forging of the punch 61 is completed, the punch head is switched by moving the position of the punch 61 up or down. After the punch of the switching head interacts with the main die 60, the bolt head is formed.

[0043] In addition, the transmission assembly 9 includes a main shaft 90 and a gear set 91 sleeved on the outer periphery of the main shaft 90. The main shaft 90 has an eccentric shaft 92 in the middle, and a pusher 93 that cooperates with the sliding push assembly 7 is sleeved on the outer periphery of the eccentric shaft 92.

[0044] Because of the eccentric shaft 92 configuration, when the main shaft 90 is powered by an external power source, the pusher 93 connected to the eccentric shaft moves forward or toward the head, thereby causing the sliding push assembly 7 to move the punch 61 closer to or further away from the main mold 60.

[0045] Specifically, the outer side of the die 61 has at least two punch holes 610 from top to bottom, and the main die 60 can have two die holes 600. Punches (not shown in the figure) that match the die holes 600 are installed in the punch holes 610. One of the die holes 600 of the main die 60 serves to place the initial forging punch after switching during the second punching process.

[0046] The aforementioned sliding push assembly 7 and lifting assembly 8 are both existing technologies. The specific structure and connection form can be referred to the technical solutions mentioned in the background art. Therefore, they at least have the beneficial effects brought about by the technical solutions of the above embodiments, and will not be repeated here. The above structure is not within the protection scope of this application.

Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
