Description

Technical Field

[0001] This utility model belongs to the field of heat treatment auxiliary tools, and specifically relates to a wire knotting device for workpieces with holes. Background Technology

[0002] In the heat treatment process of perforated workpieces, in order to achieve suspended heating treatment of the workpiece, the workpiece needs to be threaded on an iron wire, and then the iron wire is knotted to confine the workpiece within the closed area formed by the knotted iron wire, and then the workpiece is suspended in the heat treatment equipment by the iron wire.

[0003] Currently, the aforementioned wire knotting process is mainly completed manually: operators manually fold the wire passing through the workpiece's through-hole and then tie the ends together. However, in batch heat treatment production scenarios, this manual operation method has many shortcomings: First, it is inefficient, as the speed of manual knotting cannot keep up with the pace of large-scale production, thus restricting overall production efficiency; second, it suffers from poor consistency, as it relies entirely on the worker's personal experience and feel, resulting in variations in tightness, strength, and shape of knots tied by different workers, or even by the same worker under different conditions, which can easily lead to insufficient workpiece suspension stability and even detachment during heat treatment, affecting product quality; third, it is labor-intensive, as operators need to repeat mechanical knotting actions for extended periods, easily causing hand fatigue, reducing operational safety, and further exacerbating fluctuations in efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wire knotting device for workpieces with holes, so as to solve the problems of low wire knotting efficiency, poor consistency and high labor intensity of operators when heat treating workpieces with holes in batches.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wire knotting device for perforated workpieces includes a base with a front plate and a rear plate at both ends. A start button is mounted on the front plate, and a power switch and a controller are mounted on the rear plate. A protective cover is provided between the front and rear plates. A motor bracket is provided on the base, and a reducer and a motor are mounted on one side of the motor bracket. The power switch, start button, motor, and controller are electrically connected. The output shaft of the reducer is connected to a winding actuator via a coupling. The winding actuator includes a rotating shaft connected to the coupling, with a winding head fixedly connected to one end of the rotating shaft. Clamping arms are provided on both sides of the winding head, forming a clamping groove between the clamping arms and the winding head for clamping wire. The opening directions of the two clamping grooves are opposite. A wire inlet is provided on the front plate, corresponding to the position of the winding head.

[0006] Furthermore, a sensor bracket is provided on the base, and a photoelectric sensor is installed at the upper end of the sensor bracket. The photoelectric sensor is electrically connected to the controller and is used to control the number of rotations of the motor.

[0007] Furthermore, a base plate is provided on one side of the base, and a column is fixedly connected to the base plate. An anti-rotation slot is provided in the middle of the column, and the wire is placed in the anti-rotation slot during the knotting operation.

[0008] Furthermore, the inner wall of the anti-rotation slot is recessed with an arc-shaped positioning slot for accommodating and positioning the wire.

[0009] Furthermore, the upper end of the anti-rotation slot is provided with symmetrically arranged guide slopes, and the guide slopes on both sides form a funnel-shaped structure with a large opening at the top and a small opening at the bottom.

[0010] Furthermore, the base is a hollow square tube structure, and the base plate is movably inserted into the base, which facilitates adjusting the distance between the column and the winding head according to the number of knots required for the wire.

[0011] Furthermore, a support plate is provided on one side of the column for supporting the workpiece.

[0012] Furthermore, the pallet is provided with a rubber pad, which is connected to the pallet by adhesive bonding.

[0013] Furthermore, a sliding sleeve is fixedly connected to one side of the pallet, and the sliding sleeve is slidably disposed outside the column. An adjusting bolt is threadedly connected to one side of the sliding sleeve for adjusting the height of the pallet.

[0014] The beneficial effects of this utility model are: (1) This utility model utilizes a motor to drive the winding head to rotate, thereby realizing the automatic knotting of the iron wire. This not only improves the efficiency of iron wire knotting and is suitable for iron wire knotting during batch workpiece heat treatment, but also ensures the consistency of iron wire knotting and reduces the labor intensity of operators.

[0015] (2) By setting up photoelectric sensors, the number of rotations of the motor is counted and the motor is started and stopped by the controller, ensuring the consistency of the number of knots of the wire.

[0016] (3) By setting up a column and opening an anti-rotation slot on the column, the anti-rotation slot forms a circumferential limit on the wire, preventing the wire from rotating with the winding head. This eliminates the need for operators to apply reverse force to constrain the rotation of the wire, further reducing the labor intensity of the operators.

[0017] (4) A funnel-shaped guide slope is provided at the upper end of the anti-rotation slot to facilitate the quick insertion of the wire into the anti-rotation slot. An arc-shaped positioning slot is provided on the inner wall of the slot to prevent the wire from sliding longitudinally in the anti-rotation slot when knotting, thus ensuring that the wire maintains a stable posture during the knotting operation.

[0018] (5) The base plate and the base form a telescopic structure, which makes it easy to adjust the distance between the column and the winding head, so as to adapt to the number of knots of the wire.

[0019] (6) A support plate that can slide up and down along the column is provided on one side of the column to support the workpiece when the wire is knotted. This not only avoids the need for operators to manually lift the tool during the knotting process, reducing the labor intensity of the operators, but also avoids the wire loop displacement caused by the workpiece being pulled during the knotting process, which affects the knotting quality.

[0026] The following will be combined with the appendix Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. 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.

[0027] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-3 As shown, a wire knotting device for perforated workpieces includes a base 1. The base 1 has a front upright plate 2 and a rear upright plate 3 at both ends. A start button 6 is mounted on the front upright plate 2, and a power switch 5 and a controller 8 are mounted on the rear upright plate 3. A protective cover 4 is provided between the front upright plate 2 and the rear upright plate 3. A motor bracket 9 is provided on the base 1. A reducer 10 and a motor 11 are mounted on one side of the motor bracket 9. The power switch 5, start button 6, and motor 11 are electrically connected to the controller. The connection method is well known to those skilled in the art and will not be described in detail here. The output shaft of the reducer 10 is connected to a winding actuator via a coupling 12. Figure 4 As shown, the winding actuator includes a rotating shaft 13 connected to the coupling 12. One end of the rotating shaft 13 is fixedly connected to a winding head 14. The winding head 14 is provided with clamping arms 15 on both sides. The clamping arms 15 and the winding head 14 form a clamping groove for clamping the wire, and the opening directions of the two clamping grooves are opposite. The front upright plate 2 is provided with a wire inlet 7, which corresponds to the position of the winding head 14.

[0029] When knotting, first pass one end of the wire through the through hole of the workpiece, then bend the wire, and then insert both ends of the wire into the two clamping slots of the winding head 14 through the wire inlet 7. Turn on the power switch 5 and press the start button 6. The motor 11 drives the reducer 10 to rotate, which in turn drives the winding head 14 to rotate, realizing the automatic knotting of the wire. After knotting, the wire can be taken out from the wire inlet 7. This not only improves the efficiency of wire knotting and ensures the consistency of wire knotting, but also reduces the labor intensity of the operators.

[0030] like Figure 3 As shown, a sensor bracket 16 is provided on the base 1, and a photoelectric sensor 17 is installed on the upper end of the sensor bracket 16. The photoelectric sensor 17 is electrically connected to the controller 8 and is used to control the number of rotations of the motor 11. After the motor 11 rotates to the set number of rotations, the controller 8 controls the motor 11 to stop, ensuring the consistency of the number of knots in the wire.

[0031] like Figure 3As shown, a base plate 18 is provided on one side of the base 1, and a column 19 is fixedly connected to the base plate 18, such as... Figure 5 As shown, the column 19 has an anti-rotation slot 20 in the middle. When knotting, the wire is placed in the anti-rotation slot 20. The anti-rotation slot 20 forms a circumferential limit on the wire to restrict the wire from rotating with the winding head 14. This eliminates the need for the operator to apply a reverse force to constrain the rotation of the wire, further reducing the labor intensity of the operator.

[0032] like Figure 5 As shown, the inner wall of the anti-rotation slot 20 is recessed with an arc-shaped positioning slot 21, which is used to accommodate and position the wire, preventing the wire from sliding longitudinally in the anti-rotation slot 20 when knotting, and ensuring that the wire maintains a stable posture during the knotting operation.

[0033] like Figure 5 As shown, the anti-rotation slot 20 has symmetrically arranged guide slopes 22 at the upper end. The guide slopes 22 on both sides form a funnel-shaped structure with a large opening at the upper end and a small opening at the lower end, which facilitates the quick insertion of the wire into the anti-rotation slot 20.

[0034] like Figure 3 As shown, the base 1 is a hollow square tube structure, and the base plate 18 is movably inserted into the base 1, which facilitates adjusting the distance between the column 19 and the winding head 14 according to the number of knots required for the wire. For example, when knotting small workpieces, only 3-5 knots are needed to ensure the stability of the workpiece suspension, while for large workpieces with greater weight, the number of knots needs to be adjusted to 8-12.

[0035] like Figure 5 As shown, a support plate 23 is provided on one side of the column 19 to support the workpiece. On the one hand, this avoids the need for operators to manually lift the tools during the knotting process, reducing the labor intensity of the operators. On the other hand, it avoids the wire loops from shifting due to the workpiece being pulled during the knotting process, which affects the knotting quality.

[0036] like Figure 5 As shown, the pallet 23 is provided with a rubber pad 24, which is connected to the pallet 23 by adhesive bonding. The rubber pad 24 prevents the pallet 23 from scratching the surface of the workpiece.

[0037] like Figure 5 As shown, a sliding sleeve 25 is fixedly connected to one side of the support plate 23. The sliding sleeve 25 is slidably disposed outside the column 19. An adjusting bolt 26 is threadedly connected to one side of the sliding sleeve 25 to adjust the height of the support plate 23 to adapt to the support requirements of workpieces of different sizes, avoid the problem of unstable support caused by differences in workpiece size, and improve the adaptability of the device to diverse workpieces.

[0038] The above content is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of the utility model, they should all fall within the protection scope of this utility model.
