Description

Technical Field

[0001] This application relates to the technical field of wire drawing equipment, and more particularly to a flat-pressure wire drawing device specifically for cylindrical shells. Background Technology

[0002] In consumer electronics products such as refillable e-cigarette atomizers, the appearance and texture of the product casing directly affect the user's visual and tactile experience, thus influencing the overall brand image and market competitiveness. Especially for high-end models, their design not only reflects the product's differentiated positioning but also determines its overall form language. To enhance the product's texture, some models require a natural-colored brushed finish on their metal or metal-like casings. This involves mechanically creating a fine, continuous, and consistent texture on the surface while preserving the material's original color. This brushing process not only effectively conceals processing marks and improves fingerprint resistance but also gives the product a refined, modern industrial aesthetic, making it irreplaceable in the manufacturing of high-end e-cigarette casings.

[0003] Currently, the industry commonly employs manual operation for brushing product casings. Specifically, the operator first places the casing to be processed onto a rotatable fixed rod, then holds the component and actively presses the area to be brushed onto the surface of a high-speed rotating abrasive belt. During this process, the operator must rely on personal experience to control the pressure, speed, and contact angle to create the desired brushed texture on the casing surface. While this method has low equipment investment costs, it is highly dependent on manual intervention and lacks standardized operating procedures.

[0004] However, the aforementioned traditional manual wire drawing method has many significant drawbacks. First, because the force applied by hand is difficult to maintain consistently, the depth, direction, and continuity of the drawn lines are inconsistent, severely affecting the uniformity of product appearance and quality stability. This often results in rework due to non-compliance with quality inspection standards, leading to waste of materials and time. Second, the accuracy of the wire drawing position is difficult to control, easily resulting in wire area misalignment or omissions, further reducing the yield rate. Furthermore, under the action of the high-speed rotating sanding belt, the wire is easily "blown away," not only damaging the workpiece but also posing safety risks such as cuts and impacts to the operator. More importantly, this process is extremely inefficient, with a long time required to obtain a single finished piece. To meet production capacity demands, a large number of workers must be allocated, significantly increasing the company's labor costs and management burden. Therefore, there is an urgent need for an automated, high-precision, safe, and reliable wire drawing process to overcome the shortcomings of existing technologies. Summary of the Invention

[0005] This application provides a flat-pressure wire drawing device specifically for cylindrical shells, which solves the technical problem of insufficient automation in existing product shell wire drawing processes. The technical solution is as follows: This application provides a flat-pressure wire drawing device for cylindrical shells, comprising: a frame with a base mounting plate on the frame; a bearing mechanism disposed on the base mounting plate for positioning and driving the shell workpiece to be processed to perform a first rotational motion around its own axis; a wire drawing mechanism disposed on the base mounting plate and capable of feeding relative to the bearing mechanism to move closer to or away from the shell workpiece; and a drive mechanism disposed on the base mounting plate and connected to the wire drawing mechanism for driving the wire drawing mechanism to perform a second rotational motion, wherein the rotation direction of the second rotational motion is opposite to the rotation direction of the first rotational motion but the rotation speed is the same. When the wire drawing mechanism feeds toward the surface of the housing workpiece and contacts the surface of the bearing mechanism, the bearing mechanism drives the housing workpiece to rotate, and at the same time the driving mechanism drives the wire drawing mechanism to operate, so as to form the required screen printing on the surface of the housing workpiece through the friction between the wire drawing mechanism and the surface of the housing workpiece.

[0006] In one embodiment, the wire drawing mechanism includes: a support base, one end of which is adjustablely connected to a drive mechanism and the other end is detachably connected to a base mounting plate; a slide assembly mounted on the support base, with the sliding direction of the slide assembly facing the support mechanism; and a grinding assembly mounted on the slide assembly and drivenly connected to the drive mechanism, the grinding assembly being able to move toward or away from the support mechanism with the slide assembly.

[0008] In one embodiment, the grinding assembly further includes: a cylinder mounting base mounted on a slide assembly; a first drive cylinder mounted on the cylinder mounting base; a third rotary wheel mounting base mounted on the piston rod of the first drive cylinder; and a tensioning rotary wheel rotatably connected to the third rotary wheel mounting base; wherein the first drive cylinder is capable of driving the tensioning rotary wheel to abut against the inner side of the sanding belt.

[0009] In one embodiment, the grinding assembly further includes: a fourth rotary wheel mounting base slidably disposed on the slide assembly, the sliding direction of which is toward the first driven drive wheel; a clamping wheel rotatably connected to the fourth rotary wheel mounting base and located at the end of the fourth rotary wheel mounting base near the first driven drive wheel; and a quick clamp mounted on the slide assembly, the output end of which is connected to the fourth rotary wheel mounting base; wherein the quick clamp can drive the fourth rotary wheel mounting base to slide so that the clamping wheel presses against the outside of the sanding belt.

[0010] In one embodiment, the slide assembly includes: a support plate connected to a support base; two first slide rails spaced apart and mounted on the support plate; a sliding plate slidably connected to the support plate via the first slide rails, and a grinding assembly mounted on the sliding plate; and a second drive cylinder mounted on the support plate, with the piston rod of the second drive cylinder connected to the sliding plate for driving the sliding plate to reciprocate along the first slide rails.

[0011] In one embodiment, the support base includes: a locking component, fixedly mounted on a base mounting plate; an adjusting plate, one end of which has a mounting through hole that can be fitted onto the drive mechanism, and the other end is detachably connected to the locking component via a fastener; a fifth rotating wheel mounting seat, mounted on the side of the adjusting plate near the bearing mechanism; and a follower rotating wheel, rotatably connected to the fifth rotating wheel mounting seat, for abutting against the bearing mechanism.

[0012] In one embodiment, the drive mechanism includes: a first fixed base mounted on a base mounting plate; a first rotating rod rotatably disposed within the first fixed base via a bearing, with one end of the first rotating rod extending out of the first fixed base; a drive transmission wheel mounted on the end of the first rotating rod extending out of the first fixed base and connected to the wire drawing mechanism; and a first drive motor mounted on the side of the base mounting plate opposite to the first fixed base, with the output shaft of the first drive motor passing through the base mounting plate and connected to the first rotating rod.

[0013] In one embodiment, the supporting mechanism includes: a second fixed base mounted on a base mounting plate; a second rotating rod rotatably mounted in the second fixed base via a bearing, with one end of the second rotating rod extending out of the second fixed base; a rotating base mounted on the end of the second rotating rod extending out of the second fixed base; a placement platform connected to the rotating base, with an insertion hole for placing the housing workpiece provided on the top of the placement platform; and a second drive motor mounted on the side of the base mounting plate opposite to the second fixed base, the output shaft of the second drive motor passing through the base mounting plate and being drively connected to the second rotating rod, and the rotation direction of the output shaft of the second drive motor being opposite to the rotation direction of the drive mechanism.

[0014] In one embodiment, the device further includes: a fixed gantry mounted on a base mounting plate, with two opposing second slide rails mounted on the side wall of the fixed gantry, the extension direction of the two second slide rails being perpendicular to the upper surface of the base mounting plate, and sliders slidably mounted on each of the two second slide rails; a pushing mechanism disposed on the fixed gantry and located above the carrying mechanism; and a pressing mechanism connected to the pushing mechanism and corresponding vertically to the carrying mechanism; the pushing mechanism is used to drive the pressing mechanism to reciprocate along the height direction of the fixed gantry, so that the pressing mechanism has a first working position located above and a second working position located below. When the pressing mechanism is in the first working position, a clearance space is formed between the pressing mechanism and the carrying mechanism. When the pressing mechanism is in the second working position, the pressing mechanism presses downward to limit the shell workpiece on the carrying mechanism. The pushing mechanism includes: a horizontal plate connected to two sliders and located above the bearing mechanism; a third driving cylinder installed on the top of the fixed gantry, with the piston rod of the third driving cylinder connected to the horizontal plate for driving the horizontal plate to move up and down along the second slide rail; and a pressing mechanism located on the side of the horizontal plate away from the third driving cylinder, which can cooperate with the shell workpiece to rotate when the shell workpiece is driven to rotate by the bearing mechanism. The pressing mechanism includes: a fourth drive cylinder, the cylinder body of which is fixedly mounted on the horizontal plate; a third fixed seat, which is mounted on the piston rod of the fourth drive cylinder away from the horizontal plate; a third rotating rod, which is rotatably mounted in the third fixed seat through a bearing, and one end of the third rotating rod extends out of the third fixed seat; and a buffer pad, which is mounted on the end of the third rotating rod that extends out of the third fixed seat, for buffering the pressure applied by the third rotating rod to the shell workpiece.

[0015] Compared with existing technologies, the flat-pressure wire drawing device for cylindrical shells proposed in the above technical solution achieves automated wire drawing through integrated design, completely solving the problem of inconsistent patterns caused by unstable manual force application in traditional manual operations. This application uses a load-bearing mechanism to precisely position and drive the shell workpiece to rotate around its own axis, while the drive mechanism drives the wire drawing mechanism to rotate at the same speed but in opposite directions, maximizing the relative linear velocity between the shell workpiece and the wire drawing mechanism, thereby forming a uniform, continuous, and consistent-direction silkscreen on the shell surface. This design effectively avoids the uneven depth, directional deviation, and discontinuous patterns caused by improper control of pressing pressure, moving speed, and contact angle in traditional wire drawing, significantly improving the consistency of product appearance quality, greatly reducing rework rates, and minimizing material waste. This device also eliminates the safety hazards present in traditional manual wire drawing. Since the workpiece is firmly positioned on the load-bearing mechanism, there is no need for operators to hold and press the workpiece, completely avoiding the situation where the high-speed rotating sander belt "flies" the product, effectively ensuring the personal safety of operators and reducing the risk of workplace accidents. Meanwhile, the automated operation mode keeps operators away from high-speed rotating parts, further improving the safety of the working environment. This application significantly improves production efficiency and economic benefits, greatly reduces the company's need for wire drawing workers, lowers labor costs, and increases capacity utilization.

[0016] In summary, the cylindrical shell-specific flat-pressure wire drawing device of this application, through its innovative design of automation, high precision, and high safety, not only significantly improves product quality and production efficiency, but also greatly reduces safety risks and labor costs. It provides an efficient, reliable, and safe solution for the wire drawing process of high-end consumer electronics shells, and has significant technological progress and practical value.

Detailed Implementation

[0021] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0022] Reference Figure 1 and Figure 2 As shown in the embodiments of this application, a flat-pressure wire drawing device for cylindrical shells is proposed. This flat-pressure wire drawing device for cylindrical shells may include: a frame 1, on which a base mounting plate 12 is provided; a bearing mechanism 2, disposed on the base mounting plate 12, for positioning and driving the shell workpiece to be processed to perform a first rotational motion around its own axis; a wire drawing mechanism 3, disposed on the base mounting plate 12, and capable of feeding relative to the bearing mechanism 2 to move closer to or away from the shell workpiece; and a drive mechanism 4, disposed on the base mounting plate 12 and connected to the wire drawing mechanism 3 for driving the wire drawing mechanism 3 to perform a second rotational motion, the rotation direction of the second rotational motion being opposite to the rotation direction of the first rotational motion and the same speed. When the wire drawing mechanism 3 feeds toward the surface of the bearing mechanism 2 and contacts the shell workpiece, the bearing mechanism 2 drives the shell workpiece to rotate, and at the same time the driving mechanism 4 drives the wire drawing mechanism 3 to operate, so that the desired screen printing is formed on the surface of the shell workpiece through the friction between the wire drawing mechanism 3 and the surface of the shell workpiece.

[0023] Specifically, in the technical solution adopted in this application, the frame 1 includes a rectangular support frame and a base mounting plate 12 fixed on top of the support frame. The structure of the frame 1 supports the base mounting plate 12 to a height convenient for operation, while also providing ample space above and below it for assembly and maintenance. To further optimize the overall structural layout, the load-bearing mechanism 2 and the drive mechanism 4 can be partially embedded or recessed onto the base mounting plate 12, helping to reduce the overall height of the load-bearing mechanism 2 and the drive mechanism 4, making their structure more compact. The wire drawing mechanism 3 is mounted on the upper surface of the base mounting plate 12 for easy execution of processing actions. The drive mechanism 4 transmits power to the wire drawing mechanism 3, which in turn achieves contact and separation with the surface of the workpiece through its own feed motion, thereby completing the automated wire drawing operation.

[0024] The working principle is as follows: First, the cylindrical shell workpiece to be processed is placed and fixed on the bearing mechanism 2. After starting the equipment, the wire drawing mechanism 3 feeds towards the workpiece until it smoothly contacts the surface of the shell workpiece. At this time, the bearing mechanism 2 drives the workpiece to rotate at a set speed, i.e., the first rotational motion; simultaneously, the drive mechanism 4 drives the actuator of the wire drawing mechanism 3 to rotate at the same speed but in the opposite direction, i.e., the second rotational motion. In this motion state, the relative linear velocity between the shell workpiece and the wire drawing mechanism 3 is significantly increased, thereby forming a silkscreen on the radial side of the shell workpiece arranged along its axial direction; at the same time, due to the synchronous motion of the two rotations, the processing force is evenly distributed on the circumference of the workpiece, effectively ensuring the uniformity and consistency of the silkscreen. Through the continuous friction between the wire drawing mechanism 3 and the surface of the shell workpiece, a high-quality and continuous desired silkscreen can be formed on the surface of the cylindrical shell. After processing is completed, the wire drawing mechanism 3 retracts, the bearing mechanism 2 stops rotating, and the workpiece can be unloaded. This achieves efficient, high-quality, and automated wire drawing processing of cylindrical shell workpieces, with the advantages of compact structure, simple operation, and improved product consistency.

[0025] Furthermore, refer to Figure 3 As shown, in some embodiments, the wire drawing mechanism 3 includes: a support base 33, one end of which is adjustablely connected to the drive mechanism 4, and the other end is detachably connected to the base mounting plate 12; a slide assembly 32, which is mounted on the support base 33 and the sliding direction of the slide assembly 32 is towards the support mechanism 2; and a grinding assembly 31, which is mounted on the slide assembly 32 and is connected to the drive mechanism 4, and the grinding assembly 31 can move towards or away from the support mechanism 2 with the slide assembly 32.

[0026] Specifically, in the technical solution adopted in this application, the slide assembly 32 is used to drive the grinding assembly 31 to reciprocate in a linear direction, thereby achieving contact or separation between the grinding assembly 31 and the surface of the workpiece to complete automated wire drawing processing, that is, forming the required screen printing on the surface of the workpiece. The support base 33 provides the ability to adjust the overall position of the slide assembly 32 and the grinding assembly 31; when the end of the support base 33 connected to the base mounting plate 12 is disassembled, the support base 33 can be rotated around the drive mechanism 4 to adjust the relative distance between the slide assembly 32 and the grinding assembly 31 on it and the bearing mechanism 2. This adjustment mechanism can ensure that during the movement of the grinding assembly 31 driven by the slide assembly 32, the grinding assembly 31 can accurately contact or separate from the workpiece surface, effectively avoiding problems such as poor contact or incomplete separation caused by positional deviation, and improving the stability of the processing and the consistency of the screen printing quality.

[0027] Furthermore, refer to Figure 4As shown, in some embodiments, the grinding assembly 31 includes: a first rotary wheel mounting base 311, mounted on the slide assembly 32; a first driven drive wheel 312, rotatably connected to the first rotary wheel mounting base 311, with the radial outer edge of the first driven drive wheel 312 extending out of the slide assembly 32 near the support mechanism 2; a second rotary wheel mounting base 313, mounted on the slide assembly 32 and spaced apart from the first rotary wheel mounting base 311; a second driven drive wheel 314, rotatably connected to the second rotary wheel mounting base 313; and a sanding belt 315, having a closed-loop structure, and being connected to the first driven drive wheel 312, the second driven drive wheel 314, and the drive mechanism 4 in a sleeved manner.

[0028] Specifically, in the technical solution adopted in this application, the first driven drive wheel 312 and the second driven drive wheel 314 constitute the main support and guiding structure for the transmission of the abrasive belt 315. The first driven drive wheel 312, with its radially extending outer edge extending into the slide assembly 32, allows the abrasive belt 315 to directly contact the surface of the shell workpiece and perform friction processing. Driven by the drive mechanism 4, the abrasive belt 315 circulates at high speed around the first driven drive wheel 312 and the second driven drive wheel 314. This arrangement ensures that the outer side of the abrasive belt 315 can stably and comprehensively contact the radial side of the cylindrical shell workpiece under the feed of the slide assembly 32, thereby ensuring a uniform wire-drawing effect across the entire processing width. The spacing between the two wheel mounting seats determines the tension basis required for the abrasive belt 315's operation, which is crucial for ensuring smooth transmission and processing accuracy.

[0029] Furthermore, refer to Figure 4 As shown, in some embodiments, the grinding assembly 31 further includes: a cylinder mounting base 316, mounted on the slide assembly 32; a first drive cylinder 317, mounted on the cylinder mounting base 316; a third rotary wheel mounting base 318, mounted on the piston rod of the first drive cylinder 317; and a tensioning rotary wheel 319, rotatably connected to the third rotary wheel mounting base 318; wherein the first drive cylinder 317 can drive the tensioning rotary wheel 319 to abut against the inner side of the sanding belt 315.

[0030] Specifically, in the technical solution adopted in this application, the first drive cylinder 317, the third roller mounting base 318, and the tensioning roller 319 together constitute an independent tensioning mechanism for the sanding belt 315. By extending and retracting the piston rod of the first drive cylinder 317, the position of the tensioning roller 319 relative to the inner side of the sanding belt 315 can be precisely controlled. When the first drive cylinder 317 actuates, driving the tensioning roller 319 to apply pressure to the inner side of the sanding belt 315, it can compensate for the slack caused by prolonged operation, stretching, or temperature changes in the sanding belt 315, maintaining a constant preset tension. This adjustable tensioning method effectively prevents the sanding belt 315 from slipping, shaking, or deviating, and is an important technical means to ensure stable wire drawing and high screen printing consistency, while also extending the service life of the sanding belt 315.

[0031] Furthermore, refer to Figure 4 As shown, in some embodiments, the grinding assembly 31 further includes: a fourth rotary wheel mounting base 3110, slidably disposed on the slide assembly 32, with its sliding direction facing the first driven transmission wheel 312; a clamping rotary wheel 3111, rotatably connected to the fourth rotary wheel mounting base 3110, and located at the end of the fourth rotary wheel mounting base 3110 near the first driven transmission wheel 312; and a quick clamp 3112, mounted on the slide assembly 32, with its output end connected to the fourth rotary wheel mounting base 3110; wherein the quick clamp 3112 can drive the fourth rotary wheel mounting base 3110 to slide, so that the clamping rotary wheel 3111 presses against the outside of the sanding belt 315.

[0032] Specifically, in the technical solution adopted in this application, the fourth rotating wheel mounting base 3110, the clamping rotating wheel 3111, and the quick clamp 3112 constitute a clamping and fine-tuning mechanism for the sanding belt 315. Its core function is that, by operating the quick clamp 3112, the fourth rotating wheel mounting base 3110 and its clamping rotating wheel 3111 can be manually driven to slide along a specific track, thereby applying pressure to the outside of the sanding belt 315. This pressure serves a dual purpose: firstly, before work begins, it assists the tensioning mechanism in further tightening the sanding belt 315 to ensure its straightness; secondly, during processing, this clamping force allows the sanding belt 315 to fit more tightly with the first driven transmission wheel 312, enhancing the rigidity of the sanding belt 315 in the contact area and reducing deformation caused by the workpiece's reaction force, thus achieving clearer and deeper screen printing. The quick clamp 3112 provides the advantages of convenient operation and the ability to maintain a constant clamping force, making the pressure fixing process efficient and reliable. This mechanism works in conjunction with the inner tensioning mechanism to achieve precise and stable control over the tension and working state of the 315 abrasive belt.

[0033] Furthermore, refer to Figure 5As shown, in some embodiments, the slide assembly 32 includes: a support plate 321 connected to a support base 33; two first slide rails 322 spaced apart and mounted on the support plate 321; a sliding plate 323 slidably connected to the support plate 321 via the first slide rails 322; a grinding assembly 31 mounted on the sliding plate 323; and a second drive cylinder 324 mounted on the support plate 321, with the piston rod of the second drive cylinder 324 connected to the sliding plate 323 for driving the sliding plate 323 to reciprocate along the first slide rails 322.

[0034] Specifically, in the technical solution adopted in this application, the slide assembly 32 constitutes a linear module that drives the grinding assembly 31 to perform precise feed motion. The second drive cylinder 324 serves as a power source, driving the sliding plate 323 to slide linearly via its piston rod. Two parallel and spaced first slide rails 322 provide rigid and low-friction linear guidance for the sliding plate 323, ensuring that the grinding assembly 31 moves strictly in the direction pointing towards the bearing mechanism 2. This is the basis for achieving precise and stable contact and separation between the wire drawing mechanism 3 and the workpiece surface. The sliding plate 323 serves as an integrated mounting platform for the grinding assembly 31, on which functional components such as the first rotary wheel mounting seat 311, the second rotary wheel mounting seat 313, the cylinder mounting seat 316, the fourth rotary wheel mounting seat 3110, and the quick clamp 3112 are centrally mounted, enabling the entire grinding unit to reliably reciprocate as a whole. To further optimize the contact process and prevent impact, this embodiment also includes a stop 325 fixedly installed on the support plate 321, and a buffer cylinder 326 installed on the corresponding side of the sliding plate 323. When the second drive cylinder 324 drives the sliding plate 323 and the grinding assembly 31 to move towards the bearing mechanism 2 to near the end of the stroke, the buffer output head of the buffer cylinder 326 will contact the stop 325 in advance, and smoothly absorb the remaining kinetic energy through hydraulic damping, so that the movement speed of the sliding plate 323 can be linearly and gently reduced to a stop. This buffering mechanism ensures that the sanding belt 315 can smoothly contact the surface of the shell workpiece with extremely low impact force, effectively avoiding scratches on the workpiece surface, sanding belt 315 jumping or mechanism vibration caused by rigid collision. While achieving automated and efficient processing, it significantly improves the protection capability of precision workpieces and the final screen printing processing quality.

[0035] Furthermore, refer to Figure 6 As shown, in some embodiments, the support base 33 includes: a locking component 331, fixedly mounted on the base mounting plate 12; an adjusting plate 332, one end of which is provided with a mounting through hole that can be fitted onto the drive mechanism 4, and the other end is detachably connected to the locking component 331 by a fastener; a fifth rotating wheel mounting seat 333, mounted on the side of the adjusting plate 332 near the bearing mechanism 2; and a follower rotating wheel 334, rotatably connected to the fifth rotating wheel mounting seat 333, for abutting against the bearing mechanism 2.

[0036] Specifically, in the technical solution adopted in this application, the support base 33 serves to connect and support the slide assembly 32, while the adjusting plate 332 and the locking component 331 are detachably connected. After loosening the fasteners on the locking component 331, the adjusting plate 332 can rotate at a small angle around its mounting through hole (i.e., the axis of the drive mechanism 4), thereby finely adjusting the distance between the slide assembly 32 and the grinding assembly 31 and the bearing mechanism 2. After adjustment, the adjusting plate 332 is connected to the locking component 331 to fix the position. To accommodate different positions of the adjusting plate 332, multiple threaded holes can be opened on the locking component 331 so that after the adjusting plate 332 is adjusted to the target position, the two can be connected through the corresponding threaded holes and fasteners; this can compensate for accumulated mechanical assembly errors and ensure that the sanding belt 315 and the surface to be processed of the shell workpiece are always at the optimal theoretical contact distance. The follower wheel 334 installed on one side of the adjusting plate 332 plays a key auxiliary support and stabilizing role when the adjustment is completed and processing begins. The follower roller 334 always rests against a specific part of the support mechanism 2 (such as the rotary seat 23 or the non-processed area of ​​the workpiece). This has a dual beneficial effect: firstly, the follower roller 334 forms a support between the support base 33 and the support mechanism 2, precisely limiting the spatial posture between the grinding assembly 31 and the support mechanism 2, ensuring the repeatability of the contact angle and pressure between the abrasive belt 315 and the workpiece housing; secondly, when the support mechanism 2 drives the workpiece housing to rotate at high speed, the follower roller 334, as a driven constraint point, can absorb and suppress possible radial runout or vibration, significantly improving the dynamic rigidity of the entire processing system. The synergistic work of both fundamentally guarantees the extreme stability of the relative motion relationship between the abrasive belt 315 and the workpiece during the wire drawing process, which is a core technological improvement for enhancing the uniformity and consistency of screen printing.

[0037] Furthermore, refer to Figure 2 and Figure 3 As shown, in some embodiments, the drive mechanism 4 includes: a first fixed base 41, mounted on the base mounting plate 12; a first rotating rod 42, rotatably disposed within the first fixed base 41 via a bearing, with one end of the first rotating rod 42 extending out of the first fixed base 41; a drive transmission wheel 43, mounted on the end of the first rotating rod 42 extending out of the first fixed base 41, and connected to the wire drawing mechanism 3 in a transmission connection; and a first drive motor 44, mounted on the side of the base mounting plate 12 opposite to the first fixed base 41, with the output shaft of the first drive motor 44 passing through the base mounting plate 12 and connected to the first rotating rod 42 in a transmission connection.

[0038] Specifically, in the technical solution adopted in this application, in order for the drive mechanism 4 to provide the core rotational power for the wire drawing mechanism 3, the first fixed seat 41 can be fixedly installed on the base mounting plate 12 by bolts. The first fixed seat 41 supports the first rotating rod 42 through bearings, ensuring that the first rotating rod 42 can maintain extremely low runout and vibration when subjected to radial and axial loads. This is the basis for ensuring the smoothness of the second rotational motion. The active transmission wheel 43 is fixedly installed at the extended end of the first rotating rod 42 as the power output end. It is connected to the first driven transmission wheel 312 and the second driven transmission wheel 314 in the wire drawing mechanism 3 through the abrasive belt 315, so that the torque can be accurately transmitted to the abrasive belt 315. The first drive motor 44 is preferably a servo motor or a variable frequency speed control motor. The first drive motor 44 is installed below the base mounting plate 12, and its output shaft is connected to the bottom end of the first rotating rod 42 through a coupling. The layout of placing the drive motor below the mounting plate not only optimizes the overall center of gravity and reduces the height of the equipment, but also isolates the main vibration source from the working area, improving the operational stability. Servo motors or variable frequency speed control motors can precisely control drive parameters, so that the output speed and direction can be strictly set. This is one of the core control parameters for achieving efficient and uniform wire drawing process, ensuring that the second rotational motion generated by the active transmission wheel 43 driving the wire drawing mechanism 3 has a key motion relationship with the first rotational motion of the shell workpiece, which is equal in speed and opposite in direction.

[0039] Furthermore, refer to Figure 7 As shown, in some embodiments, the supporting mechanism 2 includes: a second fixed seat 21, mounted on the base mounting plate 12; a second rotating rod 22, rotatably mounted in the second fixed seat 21 via a bearing, with one end of the second rotating rod 22 extending out of the second fixed seat 21; a rotating seat 23, mounted on the end of the second rotating rod 22 extending out of the second fixed seat 21; a placement platform 24, connected to the rotating seat 23, with an insertion hole for placing the housing workpiece on the top of the placement platform 24; and a second drive motor 25, mounted on the side of the base mounting plate 12 opposite to the second fixed seat 21, the output shaft of the second drive motor 25 passing through the base mounting plate 12 and being connected to the second rotating rod 22 in a transmission manner, and the rotation direction of the output shaft of the second drive motor 25 being opposite to the rotation direction of the drive mechanism 4.

[0040] Specifically, in the technical solution adopted in this application, in order to realize the function of positioning, clamping and rotating drive of the shell workpiece by the bearing mechanism 2, the second fixed seat 21 is fixedly installed on the base mounting plate 12 by bolts. The second fixed seat 21 supports the second rotating rod 22 through bearings, providing strong radial and axial support rigidity for the entire rotating system, effectively suppressing deformation and swaying under high-speed rotation. The top of the second rotating rod 22 can be fixed to the rotating seat 23 by flange or key connection, and the placement platform 24 is fixed on the rotating seat 23. The insertion hole on the top of the placement platform 24 can be precisely designed according to the bottom shape of the shell workpiece (such as protrusion or specific interface), realizing the initial positioning and circumferential limit of the shell workpiece, and usually working with the pressing mechanism above to complete reliable clamping. The second drive motor 25 is also preferably a servo motor or a variable frequency speed control motor. The second drive motor 25 is installed below the base mounting plate 12, and its output shaft is connected to the second rotating rod 22 through a coupling. The key point is that the rotation direction of the second drive motor 25 is pre-configured to be opposite to the rotation direction of the first drive motor 44. This ensures that the first rotational motion generated by the bearing mechanism 2 driving the shell workpiece and the second rotational motion generated by the drive mechanism 4 driving the wire drawing mechanism 3 naturally satisfy the process requirement of opposite directions. Furthermore, through closed-loop synchronous speed control of the first drive motor 44 and the second drive motor 25, the rotational speeds can be precisely equal or even closer. Thus, the bearing mechanism 2 not only provides a platform for stable rotation of the shell workpiece but also, in collaboration with the drive mechanism 4, precisely establishes the dual-reverse synchronous motion relationship required for high-quality wire drawing, improving the quality of the wire drawing process and the finished product effect from the source of motion.

[0041] Furthermore, refer to Figure 2 and Figure 8 As shown, in some embodiments, a flat-press wire drawing device for cylindrical shells in this application embodiment may include: a fixed gantry 5, mounted on a base mounting plate 12, with two opposing second slide rails 51 mounted on the side wall of the fixed gantry 5, the extension direction of the two second slide rails 51 being perpendicular to the upper surface of the base mounting plate 12, and sliders 52 slidably mounted on the two second slide rails 51 respectively; a pushing mechanism 6, disposed on the fixed gantry 5 and located above the bearing mechanism 2; and a pressing mechanism 7, connected to the pushing mechanism 6 and corresponding vertically to the bearing mechanism 2; the pushing mechanism 6 is used to drive the pressing mechanism 7 to reciprocate along the height direction of the fixed gantry 5, so that the pressing mechanism 7 has a first working position located above and a second working position located below. When the pressing mechanism 7 is in the first working position, a clearance space is formed between the pressing mechanism 7 and the bearing mechanism 2. When the pressing mechanism 7 is in the second working position, the pressing mechanism 7 presses downward to limit the shell workpiece on the bearing mechanism 2. Specifically, in the technical solution adopted in this application, the fixed gantry 5, the pushing mechanism 6, and the pressing mechanism 7 jointly provide the limiting function for pressing the shell workpiece on the upper and lower parts of the bearing mechanism 2. The fixed gantry 5 serves as the rigid support frame for the pushing mechanism 6 and the pressing mechanism 7, and its bottom is fixedly installed on the base mounting plate 12, spanning above the bearing mechanism 2. Two parallel and perpendicular second slide rails 51 are symmetrically installed on the inner side of the columns of the fixed gantry 5, providing high-precision and high-rigidity vertical guidance for subsequent lifting movements. The pushing mechanism 6 provides a lifting drive function to the pressing mechanism 7, and its power output end is connected to the pressing mechanism 7. Driven by the pushing mechanism 6, the pressing mechanism 7 can switch between two key positions: First, it is raised to a relatively high position, creating ample clearance between the pressing mechanism 7 and the supporting mechanism 2 below, facilitating safe and convenient handling of the shell workpiece by the operator. Second, it descends to the working position, where the pressing mechanism 7 applies pressure to the shell workpiece on the supporting mechanism 2, applying controllable pressure from the top of the workpiece to stably press and limit it on the placement platform 24 of the supporting mechanism 2. This achieves automated clamping of the shell workpiece, ensuring the accuracy and consistency of workpiece positioning during each processing step, and is a crucial process for obtaining high-quality brushed textures.

[0042] Furthermore, refer to Figure 8 As shown, in some embodiments, the pushing mechanism 6 includes: a horizontal plate 61 connected to two sliders 52 and located above the bearing mechanism 2; a third driving cylinder 62 installed on the top of the fixed gantry 5, and the piston rod of the third driving cylinder 62 connected to the horizontal plate 61 for driving the horizontal plate 61 to move up and down along the second slide rail 51; and a pressing mechanism 7 disposed on the side of the horizontal plate 61 away from the third driving cylinder 62, which can cooperate with the shell workpiece to rotate when the shell workpiece is driven to rotate by the bearing mechanism 2. Specifically, in the technical solution adopted in this application, the pushing mechanism 6 employs a stable and reliable linear drive scheme. Its core utilizes a horizontal plate 61 as a lifting platform, with both ends of the horizontal plate 61 connected to the second slide rails 51 on both sides of the fixed gantry 5 via sliders 52. The symmetrical layout of the double slide rails and double sliders 52 ensures that the horizontal plate 61 bears uniform guiding force during lifting, effectively preventing jamming, swaying, or rotation, and guaranteeing the strict verticality of the movement trajectory. The third drive cylinder 62, providing the main power, is inverted and installed in the center of the top crossbeam of the fixed gantry 5, with its piston rod extending downwards and connected to the center of the horizontal plate 61. This top-mounted layout ensures that the third drive cylinder 62 itself does not move with the horizontal plate 61, placing the driving force application point close to the center of the horizontal plate 61, resulting in balanced force distribution. The third drive cylinder 62 is responsible for driving the entire pressing mechanism 7 to lift and lower rapidly and smoothly within a large stroke range, realizing the switching between the first and second work positions. When the system descends to the second work position, the pressing mechanism 7, located below the horizontal plate 61, begins to operate. Of particular importance is that the bottom end of the pressing mechanism 7 is designed to be rotatable. This means that when the bearing mechanism 2 drives the workpiece to rotate at high speed for wire drawing, the part of the pressing mechanism 7 that contacts the top of the workpiece can rotate passively, thereby providing the necessary downward pressure while avoiding fixed friction with the workpiece surface, preventing scratches on the top surface of the workpiece or additional resistance to the free rotation of the workpiece, and ensuring the smooth and stable rotation of the workpiece.

[0043] Furthermore, refer to Figure 8 As shown, in some embodiments, the pressing mechanism 7 includes: a fourth drive cylinder 71, the cylinder body of which is fixedly mounted on the horizontal plate 61; a third fixed seat 72, mounted on the piston rod of the fourth drive cylinder 71 away from the horizontal plate 61; a third rotating rod 73, which is rotatably mounted in the third fixed seat 72 via a bearing, and one end of the third rotating rod 73 extends out of the third fixed seat 72; and a buffer pad 74, mounted on the end of the third rotating rod 73 extending out of the third fixed seat 72, for buffering the pressure applied by the third rotating rod 73 to the housing workpiece.

[0044] Specifically, in the technical solution adopted in this application, the pressing mechanism 7 realizes a precision pressing head with flexible adjustable pressure and driven rotation function. The fourth drive cylinder 71, as the power element for applying pressure to the shell workpiece, has its cylinder body fixed on the horizontal plate 61, and the piston rod of the fourth drive cylinder 71 extends downward. By controlling the air pressure or stroke of the fourth drive cylinder 71, the pressing force finally acting on the shell workpiece can be finely and steplessly adjusted to adapt to the clamping requirements of workpieces of different materials and structures, avoiding excessive pressure causing deformation of the shell workpiece or insufficient pressure causing loosening of the shell workpiece. A third rotating rod 73 is mounted in the third fixed seat 72 connected to the end of the piston rod of the fourth drive cylinder 71 through a bearing. This design allows the third rotating rod 73 to rotate freely relative to the third fixed seat 72, while reliably transmitting the axial pressure from the fourth drive cylinder 71. The buffer pad 74 installed at the bottom end of the third rotating rod 73 is the component that directly contacts the workpiece. The buffer pad 74 is usually made of materials such as polyurethane or rubber with moderate elasticity. Its core functions are twofold: firstly, it acts as a buffer, its elastic properties absorbing and homogenizing the impact of minor unevenness or misalignment at the top of the workpiece, providing flexible initial contact and uniform pressure distribution; secondly, it enhances friction and provides protection, while providing appropriate downward pressure, its material properties increasing static friction with the workpiece surface, helping to prevent slippage during rotation, and its flexibility protecting the workpiece surface from damage. In summary, the entire pressing mechanism 7, through the coordinated design of cylinder pressure adjustment, bearing rotation, and elastic contact, achieves reliable and adjustable axial positioning of the workpiece while completely decoupling its rotational freedom.

[0045] Furthermore, refer to Figure 2 As shown, in some embodiments, it also includes: a plasma air gun 8, which is disposed on the base mounting plate 12, with the nozzle of the plasma air gun 8 pointing towards the shell workpiece placed on the support mechanism 2, for blowing away the debris generated during the processing of the shell workpiece.

[0046] Specifically, in the technical solution adopted in this application, the plasma air gun 8 can provide cleaning functionality for the shell workpiece during processing. Its technical principle lies in generating a high-speed ionized airflow (i.e., plasma wind) carrying a large number of positive and negative ions. Compared with ordinary compressed air, this ionized airflow has two significant advantages: firstly, the high-speed airflow can effectively remove processing debris adhering to the surface of the shell workpiece; secondly, the charged ions in the airflow can also charge micron-sized dust particles, making them easier to adsorb, neutralize, and directionally discharged with the airflow, resulting in higher cleaning efficiency, especially suitable for fine dust generated during metal wire drawing. Typically, the plasma air gun 8 can be activated and deactivated in conjunction with the processing steps, for example, after the wire drawing mechanism 3 retracts and the workpiece stops rotating, achieving immediate cleaning of the workpiece and fixture area, providing a clean environment for the next round of processing or the removal of the shell workpiece.

[0047] Reference Figure 1 As shown, to further achieve cleaner and safer processing, the dust cover 9 provides a physical barrier against dust. Its body is typically made of transparent or semi-transparent high-strength materials, such as polycarbonate sheets, to facilitate observation of the internal processing status. More importantly, the dust cover 9 is not simply a sealed shell; its internal space is usually connected to a negative pressure dust collection system (not shown in the figure, but possibly connected to an external dust collector via piping). During processing, the dust collection system is activated, maintaining a slight negative pressure inside the cover. At this time, debris blown up by the plasma gun 8 and dust generated during processing are guided by the airflow and cannot diffuse towards the operator; instead, they are directionally drawn into the dust collection system for filtration and collection. This not only greatly improves the working environment and protects the health of operators but also prevents dust accumulation on precision moving parts (such as slide rails and bearings), reducing equipment wear and failure rates, and ensuring the long-term operational accuracy and reliability of the equipment.
