Description

Technical Field

[0001] This invention relates to the field of brake drum forming technology, and in particular to a composite brake drum steel shell rolling and cutting integrated machine. Background Technology

[0002] The production of composite brake drums typically involves multiple processes, including spinning steel plates into a preliminary steel shell shape, cutting the large end face of the steel shell to a fixed length, and rolling the steel shell for finishing and reinforcement. Because it is difficult to guarantee absolutely uniform height of the steel shell during the spinning process, direct rolling will result in uneven finishing, affecting the quality of subsequent centrifugal casting. Therefore, the large end of the steel shell needs to be cut before rolling to obtain a precise height.

[0003] Current production processes involve using hydraulic lathes to turn the steel shell end faces, CNC vertical lathes to turn the steel shell end faces, laser cutting to cut the steel shell end faces, and plasma cutting to cut the steel shell to the required height. However, these methods have many drawbacks: for example, turning easily produces continuous steel chips that are difficult to clean, posing safety hazards and being inefficient; plasma cutting produces harmful fumes and strong light, polluting the environment and endangering workers' health. On the other hand, the roll forming process usually needs to be carried out on a separate roll forming machine, which results in a long production process, large equipment footprint, high personnel requirements, and high production costs.

[0004] Therefore, how to provide a device that can efficiently integrate steel shell cutting and rolling processes, overcome the defects of existing technologies, and improve production efficiency and product quality stability is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a composite brake drum steel shell rolling and cutting integrated machine, which can efficiently integrate steel shell cutting and rolling processes, thereby improving the production efficiency and product quality stability of steel shells.

The rolling support wheel assembly includes: Support wheel brackets are floatingly connected to the machine body; The rolling support wheel is rotatably mounted on the support wheel support. The linkage mechanism is connected between the roller cutter assembly and the support wheel support. When the roller cutter assembly is driven close to the roller mold, the linkage mechanism can drive the support wheel support to move the roller cutting support wheel against the inner wall of the steel shell placed on the roller mold.

[0012] In one possible implementation, the roller assembly includes: A rolling base is movably mounted on the upper side of the machine body; Rolling rollers are mounted on the rolling base via a rolling spindle to shape the steel shell in conjunction with the rolling mold. The second drive cylinder is located on the machine body and is used to drive the rolling base to move closer to or away from the rolling mold.

[0013] In one possible implementation, the material lifting frame is connected to the lower side of the movable beam via a height adjustment rod; The drive unit includes a main lifting cylinder and two auxiliary lifting cylinders.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this invention.

[0024] The purpose of this invention is to provide a composite brake drum steel shell rolling and cutting integrated machine, which can efficiently integrate steel shell cutting and rolling processes, thereby improving the production efficiency and product quality stability of steel shells.

[0025] To achieve the above objectives, the present invention provides the following technical solution: Please see Figures 1 to 9 This embodiment provides a composite brake drum steel shell rolling and cutting integrated machine, including: machine body 100, rolling mold 200, material lifting frame 300, rolling cutter assembly 400 and rolling wheel assembly 500.

[0026] The upper side of the machine body 100 is supported by a support plate 120 connected by multiple guide columns 110. The support plate 120 is connected to a movable beam 140 via a drive device. The movable beam 140 is slidably sleeved on the guide columns 110 and can move along the axis of the guide columns 110 under the drive device. A positioning and clamping plate 150 is rotatably mounted on the lower side of the movable beam 140. Specifically, four guide columns 110 are fixedly connected to the upper edge of the machine body 100. The top of the four guide columns 110 is fixedly connected to the support plate 120. The movable beam 140 is sleeved on the four guide columns 110. A drive device is connected between the support plate 120 and the movable beam 140 to drive the movable beam 140 to move up and down. The positioning and clamping plate 150 is rotatably connected to the lower middle part of the movable beam 140. It should be noted that the positioning and clamping plate 150 is rotatable, and its top is connected to the movable beam 140 by a bearing. Furthermore, in this embodiment, the positioning and clamping plate 150 has a positioning pin that can be inserted into the positioning hole of the steel shell flange to improve the concentricity of the steel shell and the drive shaft 210 mentioned below, and to press the steel shell onto the rolling mold 200. Moreover, in order to facilitate the detection and identification of the vertical movement position of the movable beam 140, this embodiment also has a position switch installed by a position switch bracket 121, which is suspended on one side of the support plate 120.

[0027] The rolling die 200 is installed on the upper side of the machine body 100 at the position corresponding to the positioning and clamping plate 150. It cannot rotate on its own. Only when the steel shell is pressed on the rolling die 200 will the rolling die 200 rotate. When the steel shell is being processed, it will be fitted onto the rolling die 200 and will be pressed and fixed by the positioning and clamping plate 150 to facilitate subsequent processing.

[0028] The material lifting frame 300 is suspended under the movable beam 140. It has a clearance hole in its middle to avoid the rolling mold 200. The diameter of the clearance hole is smaller than the diameter of the large end of the steel shell, so that the material lifting frame 300 can drive the steel shell to move downward to cooperate with the rolling mold 200, and move upward to lift the processed steel shell upward.

[0029] The rolling cutter assembly 400 is slidably connected to one side of the machine body 100 and is used to roll cut the steel shell fitted onto the rolling mold 200. It can be understood that rolling cut is to cut the spun steel shell to the required height. Generally, the spun steel shell is 1-2cm higher than the required height. Therefore, the rolling cut here is to remove the excess height at the lower end of the steel shell fixed on the rolling mold 200.

[0030] The forming wheel assembly 500 is slidably connected to the side of the machine body 100 opposite to the rolling cutter assembly 400, and is used to form the steel shell fitted onto the forming mold 200. It can be understood that the forming wheel assembly 500 shapes the rolled steel shell, and during this process, the lower end of the steel shell is closed. Therefore, in this embodiment, a shell-pushing cylinder is also provided on the upper side of the forming wheel assembly 500 or the rolling cutter assembly 400, which can push the steel shell to a small displacement in the horizontal direction, so that the closed steel shell can be detached from the forming mold 200, preventing the closed end of the shaped steel shell from hooking onto the lower end of the forming mold 200. For details, please refer to [link to relevant documentation]. Figure 3 The installation position of the push-shell cylinder is related to the eccentric direction of the rolling mold 200, and it is set at a position away from the eccentricity of the rolling mold 200.

[0031] This invention integrates two key processes—fixed-length cutting and roll forming—into a single machine, achieving integrated roll cutting. Through the cooperation of the movable beam 140, the discharge lifting frame, and the positioning and clamping plate 150, automatic feeding, positioning, clamping, and discharge of the steel shell are achieved. The roll cutting blade assembly 400 precisely cuts the large end of the steel shell to achieve the desired height. Then, a circular cutting mechanism linked to the roll forming wheel assembly 500 cuts off the scrap ring. Finally, the same roll forming wheel assembly 500 completes the roll forming reinforcement of the steel shell. This integrated design significantly shortens the production process, reduces equipment investment and floor space, improves production efficiency and automation, lowers labor costs and safety hazards, and ensures product dimensional consistency and stability.

[0032] In one possible implementation, the composite brake drum steel shell rolling cutter further includes a cutting assembly, which includes: an inner cutting edge 610 and an outer cutting edge 620 for cutting an annular ring; the inner cutting edge 610 for cutting an annular ring is disposed on the lower side of the rolling mold 200; the outer cutting edge 620 for cutting an annular ring is connected to the rolling wheel assembly 500 and can move with the rolling wheel assembly 500 to cooperate with the inner cutting edge 610 for cutting the annular ring cut from the steel shell.

[0033] Specifically, such as Figure 2 and Figure 3 As shown, after the excess height of the steel shell is cut off, an additional ring is left at the bottom. This ring needs to be cut off before it can be easily removed, so a ring-cutting device needs to be installed in the equipment. In this embodiment, the inner cutting edge 610 of the ring cut is located close to the rolling mold 200. When the steel shell is fitted onto the rolling mold 200, the inner cutting edge 610 of the ring cut will be located inside the steel shell. At the same time, the outer cutting edge 620 of the ring cut is located on the rolling wheel assembly 500 and can feed inward with it. The two are positioned correspondingly, so the inner cutting edge 610 and the outer cutting edge 620 of the ring cut can cooperate to cut the ring.

[0034] In one possible implementation, a drive shaft 210 is inserted through the position of the corresponding positioning and clamping plate 150 of the rolling mold 200, and the rolling mold 200 is eccentrically sleeved on the drive shaft 210. A top plate 220 is provided on the top of the drive shaft 210, which is used to cooperate with the positioning and clamping plate 150 to clamp the steel shell. The bottom end of the drive shaft 210 is connected to the output shaft of the motor 240 located on one side of the machine body 100 through a drive belt 230.

[0035] Specifically, such as Figure 3 and Figure 4 As shown, it can be understood that the steel shell is mounted on the rolling mold 200 by the material lifting frame 300. The top plate 220 of the rolling mold 200 will cooperate with the positioning and clamping plate 150 to clamp the steel shell. At the same time, the transmission shaft 210 fixedly connected to the top plate 220 will rotate under the drive of the motor 240, thereby driving the steel shell and the positioning and clamping plate 150 to rotate together, so as to facilitate the rolling and cutting of the steel shell. In this embodiment, the motor 240 is installed on the empty side of the machine body 100 through the motor bracket 241, and this article does not make specific limitations on it.

[0036] In one possible implementation, the rotary cutter assembly 400 includes: a rotary cutting base 410, a rotary cutter 420, and a first drive cylinder 440; the rotary cutting base 410 is movably mounted on the machine body 100; the rotary cutter 420 is rotatably disposed on the rotary cutting base 410 via a rotary cutting spindle 430; the first drive cylinder 440 is mounted on the machine body 100 and is used to drive the rotary cutting base 410 closer to or away from the rotary die 200.

[0037] Specifically, such as Figure 3 and Figure 4 As shown, in this embodiment, the rotary cutting spindle 430 is vertically mounted on the rotary cutting base 410, and the rotary cutting blade 420 is sleeved on the rotary cutting spindle 430 and rotates with it. It should be noted that, in order to fix the rotary cutting blade 420 and prevent it from jumping up and down, a rotary cutting blade 420 base is also sleeved on the rotary cutting spindle 430. The rotary cutting blade 420 base is located above the rotary cutting blade 420 and presses down on it. Furthermore, the rotary cutting blade 420 base can be made in sections, consisting of several pads with thicknesses of 1mm, 2mm, 5mm, 10mm, 20mm, and 0.5mm. The cutting height is generally between 260-290mm. This rotary cutting blade 420 base is made with a height of 260mm, and the remaining heights are adjusted by adding or removing shims. In other embodiments, the rotary cutting blade 420 base can also be made with a separate height-adjustable base for each product, without using thin shims to piece together the height. The advantage of this design is that it is applicable to steel shells of different heights.

[0038] In another possible implementation, a hydraulic motor 450 is mounted on top of the cutting spindle 430, and the output shaft of the hydraulic motor 450 is keyed to the cutting spindle 430. The hydraulic motor 450 is used to drive the cutting blade 420 to rotate.

[0039] Specifically, such as Figure 5 and Figure 6 As shown, in this embodiment, a hydraulic motor 450 is installed on top of the rolling spindle to add power. The hydraulic motor 450 is fixedly connected to the rolling base 410 by a flange and bolts. The output shaft of the hydraulic motor 450 is keyed to the rolling spindle 430. It should be noted that the rotation direction of the rolling cutter 420 is the same as the rotation direction of the steel shell to facilitate cutting.

[0040] In other embodiments, the hydraulic motor 450 may not be added to the cutting spindle 430, and the cutting blade 420 rotates synchronously with the steel shell when it is not powered.

[0041] In one possible implementation, a rolling support wheel assembly 700 is provided on the upper side of the machine body 100, and it is located between the rolling cutter assembly 400 and the rolling mold 200. The rolling support wheel assembly 700 includes: a support wheel support 710, a rolling support wheel 720, and a linkage mechanism. The support wheel support 710 is floatingly connected to the machine body 100. The rolling support wheel 720 is rotatably mounted on the support wheel support 710. The linkage mechanism is connected between the rolling cutter assembly 400 and the support wheel support 710, so that when the rolling cutter assembly 400 is driven close to the rolling mold 200, the linkage mechanism can drive the support wheel support 710 to drive the rolling support wheel 720 to abut against the inner wall of the steel shell placed on the rolling mold 200.

[0042] In this embodiment, the height of the rolling support wheel assembly 700 is adjustable. The rolling support wheel 720 consists of two bearings with a shaft in the middle. The lower end of the shaft is machined with an external thread and fixed to the upper side of the support wheel support 710 at the bottom. The nut is tightened, and the height of the rolling support wheel 720 is adjusted by adjusting the depth of the thread. In this way, the floating rolling support wheel assembly 700 is set up, and it automatically presses against the inner wall of the steel shell during cutting, providing effective radial support for the cutting process, preventing the steel shell from deforming or vibrating under the cutting force, and ensuring the flatness and perpendicularity of the cut surface. The floating design of the support wheel support 710 avoids interference with the steel shell during loading and unloading. The structure is ingenious and requires no additional power drive. It is important to note that the top surface of the rolling support roller 720 should be 2-3mm lower than the cutting position of the steel shell (when the steel shell is rolled, its lower end needs to be tapered, and the large diameter of the steel shell is reduced. If the position is too high, the rolling support roller 720 will press against the inner wall of the steel shell. When the steel shell rotates, it will be stuck by the tapering and cannot rotate, so the rolling cannot be completed. Therefore, the rolling support roller 720 needs to be set lower to avoid the tapering).

[0043] As a further improvement of the present invention, the linkage mechanism includes a clamping plate 731, a first contact plate 732, a second contact plate 733, and an elastic element 734. The clamping plate 731 is connected to the rotary cutter assembly 400. The first contact plate 732 cooperates with the clamping plate 731 through a first inclined surface structure. The second contact plate 733 is vertically opposite to the first contact plate 732 and connected through the elastic element 734. The second contact plate 733 cooperates with the support wheel support 710 through a second inclined surface structure. When the rotary cutter assembly 400 approaches the rotary die 200, the clamping plate 731 pushes the first contact plate 732 through the first inclined surface structure. The first contact plate 732 pushes the second contact plate 733 through the elastic element 734. The second contact plate 733 then pushes the support wheel support 710 through the second inclined surface structure, causing the rotary cutting support wheel 720 to move radially inward. For details, please refer to [link to relevant documentation]. Figure 7 This invention provides only a feasible implementation principle, and the specific configuration can be adjusted appropriately according to the actual situation.

[0044] The linkage mechanism uses an inclined plane and an elastic element 734 to convert the horizontal forward motion of the rolling cutter assembly 400 into the radial inward motion of the support wheel support 710. The transmission is reliable and the structure is compact. The setting of the elastic element 734 makes the clamping force of the support wheel on the steel shell adjustable and gentle, which not only ensures the support effect, but also avoids damage to the equipment or workpiece caused by rigid impact.

[0045] In one possible implementation, the rolling wheel assembly 500 includes: a rolling base 510, a rolling wheel 520, and a second drive cylinder 540; the rolling base 510 is movably mounted on the upper side of the machine body 100; the rolling wheel 520 is rotatably mounted on the rolling base 510 via a rolling spindle 530 to cooperate with the rolling mold 200 to shape the steel shell; the second drive cylinder 540 is disposed on the machine body 100 and is used to drive the rolling base 510 to move closer to or away from the rolling mold 200.

[0046] In this embodiment, the structure of the rolling wheel assembly 500 is similar to that of the rolling cutter assembly 400. It is installed on the other side of the machine body 100 and can roll after the steel shell is rolled. During rolling, the rolling wheel 520 moves toward the steel shell under the drive of the second drive cylinder 540 until it abuts and presses against the side wall of the steel shell. Then the steel shell rotates under the drive of the motor 240, and its side wall is gradually formed under the extrusion of the rolling mold 200 and the rolling wheel 520.

[0047] In one possible implementation, the material lifting frame 300 is connected to the lower side of the movable beam 140 via a height adjustment rod 310; it is understood that this configuration can accommodate steel shell transportation at different heights, thereby expanding the processing range of the roll cutting machine.

[0048] In this embodiment, the driving device includes a main lifting cylinder 131 and two auxiliary lifting cylinders 132. The main lifting cylinder 131 is located at the center of the support plate 120, and the two auxiliary lifting cylinders 132 are respectively located on both sides of the main lifting cylinder 131. It can be understood that using a hydraulic cylinder with a combination of main and auxiliary cylinders to drive the movable beam 140 can provide a sufficiently large clamping force and ensure the smoothness and synchronicity of the lifting process of the movable beam 140, resulting in a stable and reliable structure.

[0049] In one possible implementation, a coolant filtration system is also included. The coolant filtration system includes a three-stage filtration tank and an electromagnet 900 disposed at its bottom. The three-stage filtration tank includes a first sedimentation tank 810, a second sedimentation tank 820, and a third sedimentation tank 830 arranged sequentially adjacent to each other. The first sedimentation tank 810 is provided with an inlet 811, and the third sedimentation tank 830 is provided with an outlet 831. A first connecting port 812 is provided on the side wall between the first sedimentation tank 810 and the second sedimentation tank 820. A partition 822 is horizontally disposed in the middle of the second sedimentation tank 820 to divide the second sedimentation tank 820 into a sedimentation area and a clean water area, which are connected by the second connecting port 821. A third connecting port 832 is provided on the side wall between the second sedimentation tank 820 and the third sedimentation tank 830, and the third connecting port 832 is located in the clean water area.

[0050] In this embodiment, the steel shell is constantly rinsed and cooled by cooling water during the processing. However, iron filings may be generated during the rolling and shaping process. If these iron filings are not cleaned and filtered out in time, they will enter the space between the rolling wheel 520 and the steel shell with the cooling water, which is equivalent to adding abrasive material, increasing the wear of the rolling wheel 520, reducing the service life of the wheel, and potentially causing dimensional instability. Therefore, this invention adds a three-stage filtration tank to the coolant filtration system, such as... Figure 8-9 As shown, it includes multiple interconnected sedimentation tanks, and a strong magnet is added to the bottom of the tank to improve the filtration effect of iron filings.

[0051] Specifically, it includes a first sedimentation tank 810, a second sedimentation tank 820, and a third sedimentation tank 830 connected in sequence. Circulating cooling water enters the first sedimentation tank 810. A first connecting port 812 is opened below the side wall between the first sedimentation tank 810 and the second sedimentation tank 820. The water entering the sedimentation tank flows downwards, and under the action of gravity and electromagnetic force, iron filings are quickly adsorbed to the bottom of the first sedimentation tank 810. Water enters the second sedimentation tank 820 through the first connecting port 812, slowly reaching the second connecting port 821. Water exiting the first sedimentation tank 810 remains stationary at the bottom of the second sedimentation tank 820 for an extended period, allowing unfiltered iron filings to settle and be adsorbed in the bottom area of ​​the second sedimentation tank 820. Clean water overflows from the third connecting port 832 to the top of the second sedimentation tank 820, and then enters the third sedimentation tank 830 for further sedimentation and adsorption.

[0052] This design employs a three-stage sedimentation structure with a long water flow path and sufficient settling time. The connection port is located at the bottom, forcing water to flow at the bottom of the tank. This facilitates the settling of heavier iron filings under gravity, ensuring they make full contact with the magnetic components at the bottom, thus improving filtration efficiency and effectiveness. Furthermore, the use of an electromagnet (900) allows for controlled magnetism; during iron filings removal, the power can be turned off to demagnetize, making the adsorbed iron filings easier to detach and remove. After cleaning, the power can be turned on again to remagnetize and restore the adsorption function. Operation is convenient and maintenance is simple.

[0053] Furthermore, the sidewalls between the first sedimentation tank 810 and the second sedimentation tank 820, the partition 822, and the sidewalls between the second sedimentation tank 820 and the third sedimentation tank 830 are all detachable structures, and all three can be removed during cleaning.

[0054] The side wall between the first sedimentation tank 810 and the second sedimentation tank 820 is a first baffle, and the side wall between the second sedimentation tank 820 and the third sedimentation tank 830 is a second baffle. The sides of the first and third baffles are made of round steel or angle iron to form guide grooves. The first baffle and the partition 822 are made as a single unit. A circular groove with clearance is made at the corner of the partition 822 facing the first baffle, which mates with the round steel / angle iron of the guide groove. At the bottom of the partition 822, a steel plate or angle iron seat is provided on the side of the tank. Holes are provided on the top of the partition 822 to fix it to the side plate. Furthermore, all baffles can be reinforced with ribs to enhance their structural strength.

[0055] In summary, this invention provides a composite brake drum steel shell rolling and cutting integrated machine, which operates as follows: 1. Control the main lifting cylinder 131 and the auxiliary lifting cylinder 132 to drive the movable beam 140 to rise, so that the material lifting frame 300 is located above, and its upper surface is higher than the upper surface of the rolling mold 200.

[0056] 2. The steel shell is pushed to the top of the material lifting frame 300 by the pusher of the feeding roller conveyor. Alternatively, the steel shell can be placed on the material lifting frame 300 by other means. Then, the main lifting cylinder 131 and the auxiliary lifting cylinder 132 are controlled to drive the movable beam 140 to descend, so that the discharge lifting frame descends and the steel shell falls onto the rolling mold 200.

[0057] 3. After the material lifting frame 300 descends to its lowest height, the main lifting cylinder 131 and auxiliary lifting cylinder 132 drive the movable beam 140 to continue descending. The height adjusting rod 310 retracts and shortens. The positioning and clamping plate 150 at the lower end of the movable beam 140 descends and cooperates with the rolling mold 200 to clamp the steel shell. The positioning pins on the positioning and clamping plate 150 are inserted into the positioning holes of the steel shell flange, improving the concentricity of the steel shell and the drive shaft 210, and pressing the steel shell onto the rolling mold 200.

[0058] 4. Click the cycle start button. The drive shaft 210 drives the steel shell to rotate. The first drive cylinder 440 drives the rolling cutter 420 forward to cut off the excess steel shell. After cutting, the cut ring falls downward and lands on the outside of the inner cutting edge 610 of the ring.

[0059] 5. The first drive cylinder 440 drives the rolling cutter assembly 400 to move backward, and the rolling hydraulic cylinder drives the rolling wheel assembly 500 to move forward. The rolling wheel assembly 500 has a circular cutting outer cutting edge 620 below it, which cuts off the ring.

[0060] 6. The cut ring is picked up by a robotic arm; the rolling wheel assembly 500 continues to move forward, and the rolling wheel 520 rolls and closes the steel shell.

[0061] 7. After the rolling process is completed, the rolling wheel assembly moves backward by 500 degrees.

[0062] 8. The push cylinder pushes the steel shell to move along the eccentric direction of the rolling mold 200 to prevent the steel shell after closing from getting caught on the rolling mold 200 when it is detached.

[0063] 9. The material lifting frame rises to 300, lifting the steel shell out of the rolling mold 200.
