Description

Technical Field

[0001] The utility model belongs to the technical field of single-head wire drawing machines, and particularly relates to an automatic wire centering adjustment device suitable for single-head wire drawing machines. Background Art

[0002] In the metal products industry, wire drawing machines are essential equipment for the production and pre-processing of metal products such as steel wire, rope wire, and standard components. Wire drawing machines primarily draw wire or bar material to achieve the desired diameter, roundness, internal metallographic structure, surface finish, and straightness to meet the production requirements of various metal products. Therefore, the quality of these metal products depends heavily on the performance and precision of the wire drawing machine.

[0003] However, in actual production, taking the pulley-type wire drawing machine on our company's production line as an example, due to the friction between the payoff roller arm and the spool, as well as the fixed friction force, it is difficult to maintain a perfect match between the wire feed and wire delivery speeds during operation. When the wire delivery speed is faster than the wire feed speed, the payoff roller arm will rotate backward, resulting in less wire on the spool; conversely, if the wire delivery speed is slower than the wire feed speed, the payoff roller arm will rotate forward, increasing the wire on the spool. This speed mismatch not only increases the workload of operators, requiring them to frequently check and adjust the number of turns to prevent wire breakage, but also affects the continuity and stability of processing, reducing production efficiency.

[0004] Therefore, in response to the above problems, it is particularly important to design an auxiliary equipment with automatic wire gathering function based on the operating principle of the single-head wire drawing machine and apply it to the single-head wire drawing machine to solve the problem of matching the wire feeding and wire output speeds. Utility Model Content

[0005] In order to solve the design defect of the single-head wire drawing machine in the above background technology, that is, the problem that manual inspection and auxiliary adjustment of the number of turns are required due to the lack of automatic wire centering function, the utility model provides an automatic wire centering adjustment device suitable for the single-head wire drawing machine.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an automatic wire centering and adjusting device suitable for a single-head wire drawing machine, comprising a base plate and a column arranged thereon, a crossbeam vertically arranged at the top of the column, a swing rod and a hanger respectively arranged on the crossbeam, two arc plates and rollers are respectively arranged at the upper and lower ends of the swing rod, the two arc plates are symmetrically arranged along the center line of the swing rod, and proximity switches corresponding to the two arc plates are arranged on the hanger, the signal output ends of the two proximity switches are connected to the signal input ends of the controller through cables, and are respectively linked to the motors of the single-head wire drawing machine to form a chain control, the roller is in contact with the top surface of the reel, and drives the swing rod to swing unidirectionally when the swing arm of the pay-off roller rotates, and at the same time, the arc plate on one side approaches the proximity switch to generate a response signal, and the controller adjusts the output power of the motor in time when receiving the response signal to drive the reel to match its wire feeding speed with its wire output speed.

[0007] As a further supplement to the above technical solution, the swing arm is hinged on the mounting plate, and at least two first mounting waist holes are provided on the crossbeam. The mounting plate is mounted on the crossbeam by means of a first bolt through the first mounting waist hole. The mounting plate changes the contact position of the roller by adjusting the mounting position, thereby reducing the frequent rolling wear of the roller on the same position of the pay-off roller swing arm.

[0008] As a further explanation and limitation of the above technical solution, the swing arm includes a sleeve and a suspension rod inserted therein, a limiting bolt is provided on the lower end side wall of the sleeve, the sleeve is hinged on the mounting plate, the roller is fixed on the suspension rod, and the suspension rod uses a limiting bolt to limit its sliding and make the roller contact with the top surface of the reel.

[0009] As a further supplement to the above technical solution, at least two second mounting waist holes are provided on the crossbeam, and the hanger is installed on the crossbeam by using a second bolt through the second mounting waist hole. The hanger adjusts the installation position so that the two proximity switches maintain a suitable signal response distance with the two arc plates, thereby ensuring the sensitivity of the response signal.

[0010] As a further explanation and limitation of the above technical solution, the hanger includes a C-shaped main frame and vertical connecting plates fixed at both ends thereof, and the two proximity switches are respectively fixed on the two vertical connecting plates.

[0011] As a further supplement to the above technical solution, inclined steels are fixed on both inner sides of the C-shaped main frame, which are used to prevent deformation of both ends of the C-shaped main frame, thereby indirectly affecting the installation positions of the two proximity switches.

[0012] As a further supplement to the above technical solution, a lower support plate is provided between the column and the beam, and the lower support plate is used to prevent the beam from sagging due to gravity and affecting the swing range of the swing arm, thereby ensuring that the response signals emitted by the two proximity switches are timely and effective.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. This utility model utilizes a swing arm and hanger design with two proximity switches mounted on the hanger. Two curved plates are symmetrically arranged on the swing arm, and a roller is installed at its bottom end. The two proximity switches are interlocked with the motor of the single-head wire drawing machine via a controller. When the wire delivery speed mismatches with the wire feed speed, the swing arm of the payoff roller rotates, driving the swing arm to swing unidirectionally, triggering the proximity switches. The controller quickly responds and adjusts the motor output power to ensure that the two speeds match. This not only improves production efficiency but also reduces production failures caused by speed mismatch.

[0015] 2. This utility model utilizes a telescopic swing arm structure to adapt to various installation conditions for single-head wire drawing machines. Furthermore, the combination of the sleeve and boom, along with the use of stop bolts, ensures more flexible and reliable contact between the roller and the reel. Furthermore, adjusting the mounting plate allows for varying the roller contact position, further extending the service life of the payoff roller swing arm.

[0016] 3. This utility model ensures the sensitivity of the proximity switch's response signal by adjusting the hanger's position and installing a lower support plate. Furthermore, the combination of a C-shaped main frame and diagonal steel enhances the hanger's structural stability, preventing deformation from affecting the proximity switch's installation position. These measures collectively ensure the device's stability and reliability over extended use.

[0017] 4. The connection between the various components of this utility model is simple and clear, and it is easy to disassemble and replace. This not only reduces maintenance costs but also increases the overall service life of the equipment.

[0018] 5. After being put into use, the utility model ensures the quality of wire and production efficiency, effectively reduces manual intervention, and improves the stability and continuity of processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to further illustrate the technical solution of the present invention, Figures 1 to 5 ,According to the on-site transformation implementation process and design principles, we further illustrate the utility model through four embodiments.

[0028] As attached Figure 1 and 3 The invention relates to an automatic wire gathering and adjustment device suitable for a single-head wire drawing machine, comprising a base plate 1 and a column 2 arranged thereon, a crossbeam 3 vertically arranged at the top of the column 2, a swing rod 4 and a hanger 7 respectively arranged on the crossbeam 3, two arc plates 6 and rollers 5 are respectively arranged at the upper and lower ends of the swing rod 4, the two arc plates 6 are symmetrically arranged along the center line of the swing rod 4, and a proximity switch 8 corresponding to the two arc plates 6 is arranged on the hanger 7. The signal output ends of the two proximity switches 8 are connected to the signal input ends of the controller through cables, and are respectively linked to the motors of the single-head wire drawing machine to form a chain control. The roller 5 contacts the top surface of the reel 16, and drives the swing rod 4 to swing in one direction when the wire-releasing roller swing arm 15 rotates. At the same time, the arc plate 6 on one side approaches the proximity switch 8 to generate a response signal. When the controller receives the response signal, it promptly adjusts the output power of the motor to drive the reel 16 to match its wire feeding speed with its wire output speed. Example 2

[0029] In order to adapt to the single-head wire drawing machine under different installation conditions, we designed the swing rod into a telescopic rod structure, as shown in the attached Figure 2As shown, its specific implementation is as follows: the swing rod 4 includes a sleeve 401 and a suspension rod 402 inserted therein, a limiting bolt 403 is provided on the lower end side wall of the sleeve 401, and the roller 5 is fixed on the suspension rod 402. The suspension rod 402 uses the limiting bolt 403 to limit its sliding and make the roller 5 contact with the top surface of the reel 16. Example 3

[0030] After the device has been in use for a long time, the pay-off roller swing arm will frequently roll against the roller during rotation, causing wear on the same position of the pay-off roller swing arm, thereby affecting the service life of the pay-off roller swing arm.

[0031] In this regard, as attached Figure 2 As shown, we adopt the following scheme: mainly hinge the sleeve 401 on the mounting plate 9, set at least two first mounting waist holes 10 on the beam 3, and use the first bolt 11 to install the mounting plate 9 on the beam 3 through the first mounting waist hole 10. The mounting plate 9 changes the contact position of the roller 5 by adjusting the mounting position, so as to minimize the frequent rolling wear of the roller 5 on the same position of the pay-off roller swing arm 15 for a long time. Example 4

[0032] In order to ensure the sensitivity of the response signal sent by the proximity switch. Figure 2 As shown, we have taken the following two improvement measures: First, regarding the adjustment of the hanger position: at least two second mounting holes 12 are provided on the crossbeam 3, and the hanger 7 is installed on the crossbeam 3 using second bolts 13 through the second mounting holes 12. By adjusting the installation position, the hanger 7 maintains a suitable signal response distance between the two proximity switches 8 and the two curved plates 6, thereby ensuring the sensitivity of the response signal. Second, regarding the overall support structure: a lower support plate 14 is provided between the column 2 and the crossbeam 3. The lower support plate 14 is used to prevent the crossbeam 3 from sagging due to gravity and affecting the swing range of the swing arm 4, ensuring that the response signals emitted by the two proximity switches 8 are timely and effective.

[0033] In the above embodiment, the hanger 7 includes a C-shaped main frame 701 and vertical connecting plates 702 fixed at both ends thereof, and the two proximity switches 8 are respectively fixed on the two vertical connecting plates 702. Inclined steels 703 are respectively fixed on the two inner sides of the C-shaped main frame 701, which are used to prevent the two ends of the C-shaped main frame 701 from deformation, thereby indirectly affecting the installation position of the two proximity switches 8.

[0034] Its working principle: as shown in the attached Figure 4 and 5As shown, taking the clockwise rotation of the wire drawing machine's drum as an example, when the two pay-off roller swing arms also rotate clockwise, it means that the wire output is slow and the wire input is fast, the pay-off roller swing arm rotates forward, and the wire on the drum increases. When the above situation occurs, the roller at the lower end of the swing rod is affected by the rotation of the pay-off roller swing arm and intermittently swings to the right when crossing. At this time, the right side arc plate will also swing to the right. The proximity switch on the right will immediately receive the information that the arc plate is approaching and passing by and generate a response signal. When the controller receives the response signal, it will promptly reduce the output power of the motor. At this time, the controller controls the motor to slow down, causing the drum to rotate at a reduced speed, thereby increasing the wire input speed to achieve matching of the wire input and output speeds of the wire drawing machine; conversely, the signal control principle is the same.

[0035] This utility model cleverly combines mechanical structure, proximity switch sensors, and controller logic design to automatically match the wire feed and delivery speeds of a wire drawing machine. This not only improves production efficiency but also reduces operational complexity and the need for manual intervention. Furthermore, a series of innovative designs, such as the telescopic rod structure and the combination of hanger position adjustment and mounting plate position adjustment, further enhance the adaptability and stability of the device, providing a new solution for automated control of wire drawing machines.
