Description

Technical Field

[0001] This invention relates to the field of wire drawing equipment technology, and specifically to a quick-install wire drawing wheel device. Background Technology

[0002] As people's living standards improve, they have higher and higher demands for the surface treatment of objects. One such surface finish requirement is brushed finish, which involves grinding the product to create a new texture on an already processed surface. This alters the original mechanical texture or surface imperfections, creating a regular and relatively uniform new texture for a decorative effect. Because brushed finish can highlight the texture of metallic materials, it has gained increasing popularity and wider application. Traditional brushing methods involve installing a sanding belt on a brushing device, which is then pressed against the object's surface at high speed to create the brushed texture. After a period of use, the abrasive on the sanding belt wears down, requiring periodic replacement. Therefore, this type of circular wheel brushing device must allow for easy installation and removal of the sanding belt.

[0003] The existing wire drawing wheel device consists of main components such as a base plate, pressure plate, wedges, segmented blocks, and sliders. The pressure plate is connected to four wedges with bolts, and each segmented block is connected to a slider, which can slide linearly within the guide rail. After the sanding belt is installed, the clamping screws on the pressure plate are tightened, causing the wedges connected to the pressure plate to press down. Under the action of the wedge clamping force, the slider slides outward, driving the four segmented blocks to move outward. This is equivalent to expanding the outer diameter of the entire wheel, allowing the sanding belt to be stretched and tensioned for wire drawing. After the operation is completed, the clamping screws are loosened. Under the return force of the return spring, the four sliders retract evenly, causing all four segmented blocks to retract, making it easy to remove the sanding belt.

[0004] This wire drawing wheel device can disassemble and install sanding belts, but its structure is complex, with many types and numbers of parts. The machining precision and assembly requirements for each part are high, resulting in a long processing cycle and high costs. After the four segments are tensioned and spread out, their outer circles must be highly concentric. Even slight errors in machining precision can lead to unsatisfactory wire drawing results, often resulting in a high scrap rate. Furthermore, replacing the sanding belt requires finding a wrench to tighten the clamping bolts, which is laborious and time-consuming, making it unsuitable for many wire drawing operations with high CT (cutting time) requirements. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a quick-install wire drawing wheel device that can conveniently and quickly disassemble and install sanding belts, thereby greatly improving work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A quick-release wire drawing wheel device includes a main wheel lobe for connection to the output shaft of a polishing head. One end of the main wheel lobe is hinged to a secondary wheel lobe via a pin, and the secondary wheel lobe and the secondary wheel lobe together form an outer mounting surface for directly or indirectly clamping an abrasive belt. An opening and closing port is provided between the other end of the secondary wheel lobe and the main wheel lobe, penetrating the mounting surface. The opening and closing port can be opened to tighten the abrasive belt and closed to loosen the abrasive belt by rotating around the pin. The main wheel lobe or the secondary wheel lobe is provided with a control component that can drive the opening and closing port to open and close.

[0008] As a further improvement to the above technical solution:

[0009] The control component includes an eccentric wheel with a rotating shaft mounted on it. The eccentric wheel is hinged to the secondary wheel lobe via the rotating shaft and can rotate between an open state (opening the opening and closing) and a closed state (closing the opening and closing). The control component also includes a drive mechanism for driving the eccentric wheel to swing between the open and closed states.

[0010] The driving mechanism includes a handle, which is connected to a rotating shaft and can drive the rotating shaft to rotate.

[0011] The handle is provided with a slot for mounting a rotating shaft, and the slot is provided with a connecting shaft that is hinged to the rotating shaft.

[0012] The slot allows the handle to be fitted to one side of the main wheel or the secondary wheel.

[0013] The handle is provided with a male buckle at the end away from the slot, and a female buckle is provided on one side of the main wheel disc to be connected to the male buckle so that the handle can be locked onto the main wheel disc.

[0014] The eccentric wheel has a pad on the side that contacts the main wheel disc to improve wear resistance.

[0015] The eccentric wheel is provided with concentric circular segments, and the concentric circular segments allow the eccentric wheel to rotate within a certain range when the opening and closing opening is opened.

[0016] A rubber layer is attached to the outer side of the mounting surface, and the circle formed by the outer edge of the rubber layer when the opening 31 is opened is concentric with the output shaft of the polishing head.

[0017] A connecting plate is provided to reinforce the connection between the secondary wheel rim and the pin shaft. Compared with the prior art, the advantages of this invention are:

[0018] This invention, by hinged between the secondary and main wheel segments, alters the circumference of the mounting surface. When the circumference is at its shortest, it facilitates the installation of the sanding belt. Furthermore, a control component drives the opening of the hinge, increasing the circumference of the mounting surface and thus tightening the sanding belt. This allows for convenient and rapid disassembly and installation of the sanding belt, significantly improving work efficiency. Compared to existing wire drawing wheel devices, this invention is simpler, has fewer parts, and is easier to manufacture, greatly reducing production costs. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 As shown, the quick-release wire drawing wheel device of this embodiment includes a main wheel lobe 1 for connection to the output shaft of the polishing head. One end of the main wheel lobe 1 is hinged to a secondary wheel lobe 2 via a pin 11, and the secondary wheel lobe 2 forms an outer mounting surface 3 for directly or indirectly clamping the sanding belt. An opening 31 penetrating the mounting surface 3 is provided between the other end of the secondary wheel lobe 2 and the main wheel lobe 1. The opening 31 can be opened to tighten the sanding belt and closed to loosen it by rotating around the pin 11. A control component 4 is provided on the main wheel lobe 1 or the secondary wheel lobe 2 to drive the opening 31 to open and close. By hinged between the secondary wheel lobe 2 and the main wheel lobe 1, the circumference of the mounting surface 3 can be changed. When the circumference is shortest, it is convenient to install the sanding belt. Then, the control component 4 can drive the opening 31 to open, increasing the circumference of the mounting surface 3, thereby facilitating direct or indirect clamping of the sanding belt via the rubber layer 32. This allows for convenient and quick disassembly and installation of the sanding belt, greatly improving work efficiency. Compared with existing wire drawing wheel devices, this invention is simpler, has fewer parts, is easier to process, and greatly reduces manufacturing costs.

[0024] The main wheel 1 is mounted on the output shaft of the polishing head by four fixing bolts, and the main wheel 1 is provided with a positioning pin hole for centering.

[0025] Existing wire drawing wheel devices have a complex four-lobed drawing wheel structure, with four sets of sliders and wedges all having relative movement. These moving parts are prone to jamming if impurities enter, making them unsuitable for harsh working conditions where a large amount of impurities are generated. In contrast, this device does not have complex sliders, etc., and has a simple structure. Therefore, it has a high tolerance for impurities, is more reliable, and has lower requirements for the cleanliness of the device's internal parts.

[0026] In this embodiment, the control component 4 includes an eccentric wheel 42 mounted on a rotating shaft 41. The eccentric wheel 42 is hinged to the secondary wheel lobe 2 via the rotating shaft 41 and can rotate to switch between an open state (open opening 31) and a closed state (closed opening 31). The control component 4 also includes a drive mechanism 5 for driving the eccentric wheel 42 to swing between the open and closed states. Existing wire drawing wheel devices have four wedges and sliders in their four-lobe wire drawing wheel structure. After a certain period, these wedges and sliders wear out, reducing accuracy and requiring replacement. However, each replacement requires replacing four sets of wedges and sliders, making maintenance cumbersome and costly. In contrast, this device only requires replacing one set of eccentric wheel 42 and pad 43 after a period of use, and the parts are simple, significantly reducing manufacturing costs.

[0027] In this embodiment, the drive mechanism 5 includes a handle 51, which is connected to the rotating shaft 41 and can drive the rotating shaft 41 to rotate. By turning the handle 51, the secondary wheel lobes 2 are slowly opened, and the sanding belt begins to tighten. When the opening 31 is opened to its maximum position, the rotation of the handle 51 is stopped. The handle 51 acts as a wrench, eliminating the need to find a separate wrench to tighten or loosen the sanding belt. When changing the sanding belt, a small turn of the handle 51 is sufficient to close the opening 31, without needing to tighten the screws several times. The time required to change the sanding belt is generally less than 15 seconds, while common four-lobed mechanisms require at least 30 seconds to find a wrench and tighten the screws. Therefore, this significantly saves installation time and further improves work efficiency.

[0028] In this embodiment, the handle 51 is provided with a slot 52 for mounting the rotating shaft 41, and the slot 52 is provided with a connecting shaft 53 that is hinged to the rotating shaft 41. The handle 51 can be fitted to the main wheel 1 or the secondary wheel 2 through the slot 52 and the connecting shaft 53.

[0029] In this embodiment, the slot 52 allows the handle 51 to fit against one side of the main wheel rim 1 or the secondary wheel rim 2. The slot 52 facilitates the storage of the handle 51.

[0030] In this embodiment, a male buckle 54 is provided at the end of the handle 51 away from the slot 52, and a female buckle 12 is provided on one side of the main wheel lobes 1 to lock the handle 51 onto the main wheel lobes 1. The male buckle 54 and the female buckle 12 can conveniently fix the handle 51. When needed, the handle 51 can be pulled out from the female buckle 12 by turning the handle 51, which is convenient for both storage and use.

[0031] In this embodiment, the side of the eccentric wheel 42 that contacts the main wheel disc 1 is provided with a pad 43 to improve wear resistance. The pad 43 and the eccentric wheel 42 are hardened to ensure that their wear is controlled within a very small range after multiple opening and closing, thereby ensuring the stability of the overall device's accuracy.

[0032] In this embodiment, the eccentric wheel 42 is provided with concentric circular segments, which allow the eccentric wheel 42 to rotate within a certain range when the opening and closing port 31 is opened. The concentric circular segments prevent the opening and closing port 31 from opening to tighten the sanding belt and then immediately loosening the handle 51.

[0033] In this embodiment, a rubber layer 32 is attached to the outer side of the mounting surface 3. The circle formed by the outer edge of the rubber layer 32 when the opening 31 is open is concentric with the output shaft of the polishing head. The rubber layer 32 ensures that when the opening 31 is opened to its maximum position, the rubber layer 32 is concentric with the central pin hole, further improving the concentricity. After final processing, a wheel-repairing process can be set up to re-adjust the rims of the main and auxiliary wheel segments 2 based on the central pin hole, so as to ensure the concentricity of the rims of the main and auxiliary wheel segments 2.

[0034] In this embodiment, a connecting plate 21 is provided between the secondary wheel lobe 2 and the pin shaft 11 to reinforce the connection. The main wheel lobe 1 and the secondary wheel lobe 2 are made of aluminum alloy, while the connecting plate 21 is made of steel, thereby playing a role in strengthening the connection and avoiding the problem of insufficient strength of aluminum alloy.

[0035] The main wheel 1 and the auxiliary wheel 2 are configured to be dynamically balanced to ensure the dynamic balance of the entire device under high-speed rotation and to avoid vibration of the output shaft of the polishing head.

[0036] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the inventive concept should also be considered within the scope of protection of the present invention.
