Description

Technical Field

[0001] This utility model relates to the field of thread rolling machine technology, and in particular, to a feeding track applied to a flat thread rolling machine. Background Technology

[0002] A thread rolling machine is a specialized metalworking device primarily used to process metal wire into threaded fasteners, such as screws and bolts. It works by using one or more pairs of rotating rolling plates to rub and stretch the raw material, thus shaping it into the desired thread form. Thread rolling machines are characterized by high efficiency, precision, and ease of operation, and are widely used in fastener manufacturing, automotive manufacturing, machinery manufacturing, and other industrial fields. Using thread rolling machines can significantly improve production efficiency and reduce production costs, making them an indispensable piece of equipment in modern industrial production.

[0003] Currently, Chinese patent CN109604487A discloses a guide rail for a thread rolling machine, including a base plate and two limiting plates disposed on the base plate, forming a feeding channel through the spaced-apart limiting plates. Two rotatable brush rollers are positioned opposite each other within the feeding channel. When the workpiece is fed along the rail, the two brush rollers clean the workpiece, thereby removing impurities adhering to it. However, the two brush rollers can actually be described as having an approximately tangential fit, which results in incomplete cleaning of the workpiece along its axial direction. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a feeding track for use in flat wire rolling machines.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A feeding track for use on a flat wire rolling machine includes two opposing limiting plates, with a feeding channel defined between the two limiting plates. A mounting plate is rotatably disposed within the feeding channel, and a cleaning rod is disposed on the mounting plate. The cleaning rod extends along the axial direction of the workpiece, and a cleaning component is disposed on the side wall of the cleaning rod. The mounting plate is used to drive the cleaning rod to rotate between a first position and a second position on both radial sides of the workpiece. The connecting axis of the cleaning rod at the first position and the second position forms an angle with the axis of the feeding channel.

[0007] Preferably, there are two opposing sweeping rods.

[0008] Preferably, the included angle is 90 degrees.

[0009] Preferably, the mounting plate has a material receiving port in the middle.

[0010] Preferably, the sweeping rod is also adapted to change its installation position radially.

[0011] Preferably, the mounting plate is provided with a plurality of threaded holes spaced radially apart, and the cleaning rod is screwed into one of the threaded holes.

[0012] Preferably, the cleaning component includes brush bristles.

[0013] The beneficial effects of this invention are: the cleaning rod rotates around the workpiece under the drive of the mounting plate, during which the cleaning component can clean the surface of the workpiece. Compared with the prior art, the feeding track of this invention can achieve thorough cleaning of the workpiece without dead angles while the workpiece is being transported, and it is less likely that impurities will still adhere to the workpiece.

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figure 1 As shown, a feeding track for use in a flatbed thread rolling machine includes two opposing limiting plates 1. For example, the two limiting plates 1 can be supported on the machine body of the thread rolling machine via a base, particularly between a feeding mechanism and a conveying mechanism. A feeding channel 2 is thus defined between the two limiting plates 1. This feeding channel 2 is designed to receive a workpiece 8 from the feeding mechanism and guide the workpiece 8 towards the conveying mechanism until the conveying mechanism pushes the workpiece 8 into the thread rolling plate to complete the thread rolling process.

[0019] The above are the conventional components of thread rolling dies in the existing technology. Their specific principles and structures will not be elaborated here.

[0020] The difference lies in that a rotatable mounting plate 3 is provided inside the feeding channel 2, and a cleaning rod 4 is also provided on the mounting plate 3. The cleaning rod 4 and the workpiece 8 inside the feeding channel 2 have a roughly parallel axis. In addition, a cleaning component 5 is provided on the side wall of the cleaning rod 4, such as a brush or a sponge.

[0021] like Figure 1 , Figure 2 As shown, in the specific feeding process, the workpiece 8 undergoes a displacement of a preset stroke per unit time under the drive of the feeding mechanism. For example, a cylinder or other ejection mechanism can be set on the feeding track, and the workpiece 8 can undergo controllable displacement under the preset ejection stroke; or, in the example of vibratory feeding, the controllable displacement of the workpiece 8 can be achieved by controlling the inclination of the feeding track and / or the power of the vibratory motor.

[0022] The rotation of the mounting plate 3 is designed so that the cleaning rod 4 rotates between a first position and a second position on both radial sides of the workpiece 8. That is, a single drive rotation of the mounting plate 3 will place the cleaning rod 4 in either the first or second position, rather than in between. Imagine that when the cleaning rod 4 is in the first position, the preceding workpiece 8 can move to be opposite it. At this point, the mounting plate 3 rotates, the cleaning rod rotates to the second position and completes the cleaning of the workpiece 8's surface, and then the workpiece 8 can move again to a position offset from the cleaning rod 4. This is because the cleaning rod 4 is radially offset from the workpiece 8 in both the first and second positions, thus minimizing interference with the normal movement of the workpiece 8.

[0023] In a preferred example, the connecting axis of the cleaning rod 4 in the first and second positions is adapted to form a 90-degree angle with the axis of the feeding channel 2. It can be understood that regardless of whether the cleaning rod is in the first or second position, its radial distance from the workpiece 8 is maximized. This reduces the rotational accuracy requirements of the mounting plate 3 and makes it less likely for the cleaning rod 4 to collide with the workpiece 8.

[0024] For example, two cleaning rods 4 can be placed opposite each other on the same mounting plate 3. In this case, the mounting plate 3 only needs to be rotated 180 degrees to achieve a complete circumferential cleaning of the workpiece 8. Of course, multiple mounting plates 3 can also be set along the feeding channel 2, and the cleaning rods 4 on different mounting plates 3 can be set in different positions. The workpiece 8 can be completely cleaned in all directions by the cooperation of multiple cleaning rods 4.

[0025] In some embodiments, the cleaning rod 4 can also be adapted to change its mounting position on the mounting plate 3 radially. For example, a plurality of threaded holes 7 can be provided radially spaced on the mounting plate 3, thereby allowing the cleaning rod 4 to be screwed into one of the threaded holes 7 to achieve radial mounting position adjustment. In this way, the cleaning diameter of the cleaning rod 4 can be adjusted, thereby enabling the cleaning of workpieces 8 with different diameter specifications.

[0026] For example, the rotation of the mounting plate 3 can be driven by a motor, and the power transmission between the motor and the mounting plate 3 can be achieved through gear transmission or pulley transmission. In addition, a material receiving port 6 is provided in the middle of the mounting plate 3, through which impurities swept out by the cleaning rod 4 can be discharged downward through the material receiving port 6.

[0027] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
