Description

Technical Field

[0001] This application belongs to the technical field of auxiliary devices for wire drawing machines, and particularly relates to a wire drawing machine guide frame. Background Technology

[0002] Wire drawing machines are pre-processing equipment used in the production of standard parts and other metal products. Their purpose is to draw wires produced by steel manufacturers and transported to standard parts and other metal product manufacturers, so that the wires meet the raw material processing requirements for the production of standard parts and other metal products in terms of diameter, roundness, internal metallographic structure, surface finish and straightness.

[0003] Therefore, the quality of wire pretreatment by wire drawing machines directly affects the product quality of metal product manufacturers such as standard parts; wire drawing machines belong to the metal product equipment industry and are widely used in the production and pre-processing of metal products such as steel wire, rope wire, prestressed steel wire, and standard parts.

[0004] In the metal wire processing, the wire is fed into the wire drawing machine through the wire guide frame. In order to ensure the wire tension, it is generally necessary to set a height of two to three meters to ensure that the wire tension is stable and controllable.

[0005] However, when threading and changing wires on existing wire guide frames, on-site production personnel must climb to a height of several meters to work. This is not only inconvenient and inefficient, but also poses a safety hazard of falling from heights and significantly increases labor intensity and downtime. Utility Model Content

[0006] This application provides a wire drawing machine guide frame, which can solve the problems of low production efficiency and safety hazards of high-altitude operations in existing wire drawing machine guide frames.

[0007] This application provides a wire drawing machine guide frame, including a base plate, a support frame, a support rod, a sliding sleeve, a guide frame, a guide wheel assembly, and a first linear drive mechanism. The support frame is mounted on the base plate. The support rod is mounted on the end of the support frame away from the base plate, and the length direction of the support rod is consistent with the height direction of the base plate. The sliding sleeve is sleeved on the support rod and can slide along the length direction of the support rod. One end of the guide frame is connected to the outer wall of the sliding sleeve, and the other end extends away from the sliding sleeve. The guide wheel assembly includes a first guide wheel and a second guide wheel mounted on the guide frame and a third guide wheel mounted on the support frame.

The first guide wheel is set on the side of the guide frame away from the sliding sleeve, and the second guide wheel is set on the side of the guide frame close to the sliding sleeve. In particular, along the length direction of the support rod, a tangent line of the third guide wheel is tangent to the second guide wheel.

[0010] Optionally, the outer side of the sliding sleeve is also provided with a second linear drive mechanism. The second linear drive mechanism has a fixed end for fixing and an output end that can extend or shorten. The fixed end of the second linear drive mechanism is rotatably connected to the sliding sleeve, and the output end of the second linear drive mechanism is rotatably connected to the guide frame. The second linear drive mechanism is used to drive the guide frame to swing in a direction perpendicular to the length direction of the support rod.

[0011] Optionally, the outer side of the slide sleeve is also provided with a mounting part, one end of which is connected to the slide sleeve, and the other end extends away from the slide sleeve. The fixed end of the second linear drive mechanism is rotatably connected to the end of the mounting part away from the slide sleeve.

[0012] Optionally, the rotation axis of the guide frame is tangent to the second guide wheel and the third guide wheel respectively. The guide frame is provided with a first wire passage hole, which is a through hole. The center of the first wire passage hole is located on the rotation axis of the guide frame and between the second guide wheel and the third guide wheel. Correspondingly, the sliding sleeve is provided with a second wire passage hole. The first wire passage hole and the second wire passage hole are used to allow the wire to pass through the second guide wheel and enter the third guide wheel.

[0013] Optionally, a guide ring is provided on the bottom side of the guide frame, the top side of the guide ring is connected to the bottom side of the guide frame, the plane of the guide ring is consistent with the length direction of the support rod, and the axis of the guide ring is tangent to the wheel surface of the first guide wheel.

The sliding sleeve drives the guide frame and the first and second guide wheels to move to the bottom of the support rod. The worker passes the wire through the first guide wheel, the second guide wheel and the third guide wheel in sequence, and then into the feed port of the wire drawing machine. Subsequently, the first linear drive mechanism drives the sliding sleeve to move the guide frame and the first and second guide wheels to the top of the support rod. In this way, when facing wire threading and changing, the production personnel do not need to work at height and can complete the wire threading and changing work directly on the ground, which improves production efficiency and reduces safety hazards.

[0049] Currently, existing wire drawing machines suffer from low production efficiency and safety hazards due to the fixed height of the wire guide frame.

[0050] To address the aforementioned problems, one embodiment of this application provides a wire drawing machine guide frame, such as... Figure 1As shown, the wire drawing machine's lead frame includes a base plate 1, a support frame 2, a support rod 3, a sliding sleeve 4, a guide frame 5, a guide wheel assembly 6, and a first linear drive mechanism 7. The support frame 2 is mounted on the base plate 1. The support rod 3 is mounted on the end of the support frame 2 away from the base plate 1, and the length direction of the support rod 3 is consistent with the height direction of the base plate 1. The sliding sleeve 4 is fitted onto the support rod 3 and can slide along the length direction of the support rod 3. One end of the guide frame 5 is connected to the outer wall of the sliding sleeve 4, and the other end extends away from the sliding sleeve 4. The guide wheel assembly 6 includes a first guide wheel 61 and a second guide wheel 62 mounted on the guide frame 5, and a third guide wheel 63 mounted on the support frame 2. The guide wheel assembly 6 is used for feeding wires. The first linear drive mechanism 7 is mounted on the support rod 3 and has an output end that can move linearly along the length direction of the support rod 3. The output end of the first linear drive mechanism 7 is connected to the sliding sleeve 4 and can drive the sliding sleeve 4 to slide along the length direction of the support rod 3.

[0051] When the wire drawing machine wire frame provided in this embodiment is in use, the base plate 1 is fixed at a preset position on the production site. The first linear drive mechanism 7 moves the sliding sleeve 4 from above the support rod 3 to below. The sliding sleeve 4 drives the guide frame 5 and the first guide wheel 61 and the second guide wheel 62 to move to the bottom of the support rod 3. The worker passes the wire through the first guide wheel 61, the second guide wheel 62 and the third guide wheel 63 in sequence, and then enters the feed port of the wire drawing machine. Subsequently, the first linear drive mechanism 7 uses the sliding sleeve 4 to drive the guide frame 5 and the first guide wheel 61 and the second guide wheel 62 to move to the top of the support rod 3. In this way, when facing wire threading and changing, the production personnel do not need to perform high-altitude operations and can complete the wire threading and changing work directly on the ground, which improves production efficiency and reduces safety hazards.

[0052] In a specific embodiment, such as Figures 1 to 3 As shown, the first linear drive mechanism 7 is a lead screw and slider assembly (not shown in the figure). The length direction of the lead screw (not shown in the figure) in the lead screw and slider assembly is consistent with the length direction of the support rod 3. Mounting plates 31 extend from both ends of the support rod 3 in a direction perpendicular to the length of the support rod 3. The two ends of the lead screw are rotatably connected to the two mounting plates 31 of the support rod 3. The slider (not shown in the figure) in the lead screw and slider assembly is screwed to the sliding sleeve 4. The drive device (not shown in the figure) in the lead screw and slider assembly is a motor (not shown in the figure). The motor is mounted on the mounting plate 31 located at the top of the support rod 3. The output shaft of the motor is connected to one end of the lead screw to drive the lead screw to rotate. The motor can be electrically connected to an external power source to drive the lead screw to rotate and drive the slider to move along the length direction of the lead screw under the action of the limiting member of the lead screw and slider assembly, so as to drive the sliding sleeve 4 to slide along the length direction of the support rod 3. The above-mentioned lead screw and slider assembly is a commonly used assembly in the prior art, so its structure will not be described in detail here.

[0053] In some embodiments of this application, the inner surface of the sliding sleeve is inlaid with engineering plastic, that is, the contact surface between the sliding sleeve and the support rod is inlaid with engineering plastic.

[0054] Specifically, the aforementioned engineering plastic is polyamide (PA). Due to its low coefficient of friction and good self-lubricating properties, it can reduce friction when the sleeve slides relative to the support rod, making the sliding between the two smoother.

[0055] In some embodiments, lubricant is applied directly between the sleeve and the support rod to make the sliding between them smoother.

[0056] In another specific embodiment, the inner side of the sliding sleeve 4 is inlaid with engineering plastic, and a lubricant is used in conjunction to further improve the lubrication effect.

[0057] In some embodiments of this application, such as Figure 3 As shown, the sliding sleeve 4 is provided with a fixing hole 41, which is a through hole. The support rod 3 is provided with a positioning hole 32 corresponding to the fixing hole 41. There are multiple positioning holes 32, which are spaced apart along the length of the support rod 3.

[0058] When the sliding sleeve 4 slides to the preset position, the fixing hole 41 is aligned with the corresponding positioning hole 32. At this time, a pin or rod can be inserted into the fixing hole 41 and the positioning hole 32 to achieve relative fixation between the sliding sleeve 4 and the support rod 3, which can reduce the load on the first linear drive mechanism 7 and improve its working life.

[0059] In some embodiments of this application, such as Figures 1 to 5 As shown, the guide frame 5 is rotatably connected to the outer wall of the sliding sleeve 4, and the guide frame 5 can swing in a direction perpendicular to the length direction of the support rod 3.

[0060] The aforementioned guide frame 5 can swing in a direction perpendicular to the length of the support rod 3 to accommodate wires entering at different angles. In actual production, bundles of wires need to be transported to the bottom of the wire guide frame. Often, the position of the wires transported to the bottom of the wire guide frame is not fixed. When the wires enter the guide frame 5, there is a problem of the wires slipping due to excessive angle. The guide frame 5 can swing in a direction perpendicular to the length of the support rod 3, which can well accommodate wires entering from different directions, so that the wires enter the guide frame 5 and the guide wheel assembly 6 at a suitable angle.

[0061] In some embodiments of this application, such as Figures 1 to 3As shown, the first guide wheel 61 and the second guide wheel 62 are coplanar. The first guide wheel 61, the second guide wheel 62 and the third guide wheel 63 can all rotate around their own axes. The axes of the first guide wheel 61, the second guide wheel 62 and the third guide wheel 63 are all perpendicular to the length direction of the support rod 3. The first guide wheel 61 is located on the guide frame 5 away from the sliding sleeve 4, and the second guide wheel 62 is located on the guide frame 5 near the sliding sleeve 4. In particular, along the length direction of the support rod 3, a tangent line of the third guide wheel 63 is tangent to the second guide wheel 62.

[0062] The first guide wheel 61 and the second guide wheel 62 are coplanar, which ensures high stability of the wire between the first guide wheel 61 and the second guide wheel 62, preventing the wire from slipping and detaching from the wheel surfaces of the first guide wheel 61 and / or the second guide wheel 62. The axes of the first guide wheel 61, the second guide wheel 62, and the third guide wheel 63 are all perpendicular to the length direction of the support rod 3. The third guide wheel 63 is mounted on the support frame 2, and along the length direction of the support rod 3, a tangent line of the third guide wheel 63 is tangent to the second guide wheel 62. The cable is positioned such that after passing through the first guide wheel 61 and the second guide wheel 62 in sequence, the cable enters the third guide wheel 63 precisely on the aforementioned tangent line. This section of the cable forms a straight line parallel to the support rod 3, ensuring that the cable between the second guide wheel 62 and the third guide wheel 63 is always on the aforementioned tangent line. This reduces the risk of the cable slipping off the second guide wheel 62 and / or the third guide wheel 63 due to the inconsistent angle between the second guide wheel 62 and the third guide wheel 63. The direction in which the cable enters the third guide wheel 63 is fixed, resulting in better stability.

[0063] In some embodiments of this application, as shown in the figure, a second linear drive mechanism 8 is also provided on the outer side of the sliding sleeve 4. The second linear drive mechanism 8 has a fixed end for fixing and an output end that can be extended or shortened. The fixed end of the second linear drive mechanism 8 is rotatably connected to the sliding sleeve 4, and the output end of the second linear drive mechanism 8 is rotatably connected to the guide frame 5. The second linear drive mechanism 8 is used to drive the guide frame 5 to swing in a direction perpendicular to the length direction of the support rod 3.

[0064] The swing of the guide frame 5 can be controlled by the second linear drive mechanism 8. The swing amplitude of the guide frame 5 can be adjusted by controlling the extension and retraction stroke of the second linear drive mechanism 8.

[0065] In some specific embodiments, the second linear drive mechanism is a cylinder, and the cylinder's air source interface is connected to an external air source to drive the guide frame to swing.

[0066] In some embodiments, the second linear drive mechanism is an electric push rod, the power input end of which can be connected to an external power source to drive the guide frame to swing.

[0067] In some embodiments of this application, such as Figure 1 and Figures 3 to 5 As shown, the outer side of the sliding sleeve 4 is also provided with a mounting part 42. One end of the mounting part 42 is connected to the sliding sleeve 4, and the other end extends in a direction away from the sliding sleeve 4. The fixed end of the second linear drive mechanism 8 is rotatably connected to the end of the mounting part 42 away from the sliding sleeve 4.

[0068] The installation part 42 described above facilitates the installation of the second linear drive mechanism 8 and reduces the impact on the extension and retraction stroke of the output end of the second linear drive mechanism 8.

[0069] In some embodiments of this application, such as Figures 1 to 5 As shown, the rotation axis of the guide frame 5 is tangent to the second guide wheel 62 and the third guide wheel 63 respectively. The guide frame 5 is provided with a first wire passage hole 51, which is a through hole. The center of the first wire passage hole 51 is located on the rotation axis of the guide frame 5, and the center of the first wire passage hole 51 is located between the second guide wheel 62 and the third guide wheel 63. Correspondingly, the sliding sleeve 4 is provided with a second wire passage hole 44. The first wire passage hole 51 and the second wire passage hole 44 are used to allow the wire to pass through the second guide wheel 62 and enter the third guide wheel 63.

[0070] In the above embodiments, such as Figures 1 to 5 As shown, the sliding sleeve 4 has mounting protrusions 43 at both ends in the length direction. The guide frame 5 is rotatably connected to the two mounting protrusions 43 at both ends in the length direction. Specifically, the mounting protrusions 43 extend away from the support rod 3, and their extension direction is perpendicular to the length direction of the support rod 3. A bearing seat is provided on the mounting protrusion 43. Correspondingly, a bearing is provided on the guide frame 5. The guide frame 5 can swing relative to the sliding sleeve 4 in a direction perpendicular to the length direction of the support rod 3 through the cooperation of the bearing and the bearing seat. The bearing seat at the bottom of the sliding sleeve 4 is a hollow bearing seat. Correspondingly, the bearing at the bottom of the guide frame 5 is a hollow bearing. The second wire hole 44 is opened on the mounting protrusion 43 at the bottom of the sliding sleeve 4, corresponding to the hollow bearing.

[0071] It is understood that the bearing housing and bearing are conventional rotating connection methods. Other existing methods can also be used to achieve the same result. For example, a pin is provided on the mounting protrusion 43, and a corresponding pin hole is provided on the guide frame 5. The pin on the mounting protrusion 43 at the bottom of the sliding sleeve 4 is a hollow pin. The first wire passage hole 51 is connected to the pin hole at the bottom of the guide frame 5 to form a through hole, so as to achieve the effect of the guide frame 5 rotating relative to the sliding sleeve 4 while allowing the wire to pass through.

[0072] In some embodiments of this application, the wheel surfaces of the first guide wheel, the second guide wheel, and the third guide wheel are all recessed in the middle. For example, the wheel surfaces of the first guide wheel, the second guide wheel, and the third guide wheel are U-shaped wheel surfaces / V-shaped wheel surfaces.

[0073] The recessed design in the center of the first, second, and third guide wheels effectively reduces the risk of the wire slipping off the wheel surface.

[0074] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a guide ring 9 is provided on the bottom side of the guide frame 5. The top side of the guide ring 9 is connected to the bottom side of the guide frame 5. The plane where the guide ring 9 is located is consistent with the length direction of the support rod 3. The axis of the guide ring 9 is tangent to the wheel surface of the first guide wheel 61.

[0075] The aforementioned guide ring 9 can prevent excessive friction between the wire and the guide frame 5 when the wire passes through the guide frame 5 and enters the first guide wheel 61, thus providing initial guidance for the wire.

[0076] In some embodiments of this application, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the guide ring 9 is composed of multiple ring structures, which are coaxial and have increasing diameters from top to bottom.

[0077] The aforementioned guide ring 9 is composed of multiple ring structures, which can satisfy the ring swing when the wire enters and limit its swing amplitude to prevent the wire from swinging too much and bending when entering the guide frame 5 and the first guide wheel 61.

[0078] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the support frame 2 has a wire guide section 21, one end of which extends away from the support frame 2. The wire guide section 21 has a third wire guide hole 211, the center of which is located on the rotation axis of the guide frame 5. The wire passes through the first guide wheel 61, the second guide wheel 62, the first wire guide hole 51, the second wire guide hole 44, the third wire guide hole 211 and the third guide wheel 63 in sequence before entering the feed inlet of the wire drawing machine.

[0079] The aforementioned third wire hole 211 further limits the position of the wire between the second guide wheel 62 and the third guide wheel 63, preventing the wire from swinging at this point and causing it to slip off the wheel surfaces of the first guide wheel 61, the second guide wheel 62 and the third guide wheel 63.

[0080] In some embodiments of this application, such as Figures 1 to 3 As shown, the support frame 2 has an n-shaped frame structure. The support rod 3 is set on the closed end of the support frame 2. One end of the support rod 3 is connected to the closed end of the support frame 2. The open end of the support frame 2 is connected to the base plate 1. The third guide wheel 63 is set inside the support frame 2.

[0081] The aforementioned support frame 2 has an n-shaped frame structure, which can better support the support rod 3, and its opening has a certain installation space, so that the third guide wheel 63 can be easily installed inside the support frame 2.

[0082] In some embodiments of this application, such as Figures 1 to 3 As shown, a reinforcing rib 10 is provided at the connection between the support frame 2 and the base plate 1.

[0083] The aforementioned reinforcing rib 10 is used to increase the connection strength between the support frame 2 and the base plate 1.

[0084] In some specific embodiments, such as Figures 1 to 3 As shown, the support rod 3 is a square rod, and correspondingly, the sliding sleeve 4 is also a square sliding sleeve 4. The fixing hole 41 and the mounting protrusion 43 are located on opposite outer sides of the sliding sleeve 4, and the mounting part 42 and the first drive mechanism are located on the other opposite sides of the sliding sleeve 4.

[0085] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
