Description

Technical Field

[0001] The utility model relates to a technical field, specifically, to an aluminum alloy flange forging and spraying device. Background Art

[0002] Aluminum alloy flanges need to be forged during the processing process. In order to avoid sticking between the high-temperature flange and the forging die, a demolding material is sprayed into the die cavity during the forging process.

[0003] However, since the forging process requires manual operation, and the demolding material exists in powder form, it is easy for workers to inhale it during the spraying process, causing respiratory problems. Long-term contact with powdered materials may cause skin allergies or dermatitis, which is not conducive to creating a healthy working environment. Utility Model Content

[0004] The utility model provides an aluminum alloy flange forging spraying device, which can wrap the upper mold and the lower mold through a pair of protective plates, thereby greatly reducing the overflow of the release agent during the spraying process of the release agent and effectively reducing the contact between workers and the release agent.

[0005] To this end, the technical solutions adopted are as follows:

[0006] An aluminum alloy flange forging and spraying device includes a forging machine, which includes a forging assembly formed by an upper die and a lower die. There is a protective plate on each side of the forging assembly. The two protective plates are symmetrically arranged and each protective plate is driven by a driving assembly so that it can move away from or approach the forging assembly.

[0007] A bracket with an inner cavity is fixed on the inner wall of the protective plate, and a plurality of nozzles connected to its inner cavity are fixed on the bracket. A release agent box is fixed on the forging machine, and a delivery pump is provided inside the release agent box, and the delivery pump is connected to the inner cavity of the bracket through a hose.

[0008] A further technical solution is that the two protective plates are semi-annular structures that can be buckled together, and the buckling inner diameter of the two is larger than the diameter of the forging component.

[0009] A further technical solution is that the drive assembly includes a servo motor and a bidirectional screw driven to rotate by the servo motor, the bidirectional screw is rotatably connected to the frame of the forging machine, and both ends of the bidirectional screw are respectively provided with a mounting block that matches its thread through a threaded sleeve, and the two mounting blocks are respectively fixed to the protective plates on both sides.

[0010] A further technical solution is that the drive assembly further includes a limit rod arranged in parallel with the bidirectional screw rod and fixed to the frame of the forging machine, and the two mounting blocks are both slidably connected to the limit rod.

[0011] A further technical solution is that a switch electrically connected to the delivery pump is installed on the release agent box, and a spring is sleeved on the switch, the two ends of the spring are respectively connected to the release agent box and the spring, and a pressing block is fixed on the mounting block. When the two protective plates are driven by the driving assembly to engage with each other, the pressing block contacts the switch and generates a force on the spring.

[0012] A further technical solution is that the plurality of nozzles are distributed on the bracket in two rows, one above the other, and the nozzles in the two rows are tilted in two directions, respectively.

[0013] The working principle and beneficial effects of this application are:

[0014] 1. A pair of protective plates can be used to wrap the upper mold and the lower mold, thereby greatly reducing the overflow of the release agent during the spraying process, effectively reducing the contact between workers and the release agent, and protecting the health of workers.

[0015] 2. Due to the blocking of a pair of protective plates, the sprayed release agent gathers on the inner side of the pair of protective plates, so that most of the release agent can be attached to the active ends of the upper mold and the lower mold, thereby improving the utilization rate of the release agent and reducing waste.

[0016] 3. By setting the pressing block and the switch, the release time of the release agent can be controlled to ensure that the release agent is released only when a pair of protective plates are merged, which reduces the overflow of the release agent and the waste of the release agent.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1 、 2 and Figure 4 As shown, the present application provides an aluminum alloy flange forging foaming device, including a forging machine 1, wherein the forging machine 1 includes a forging assembly formed by an upper die 2 and a lower die 3, and each side of the forging assembly has a protective plate 5, the two protective plates 5 are symmetrically arranged and each protective plate 5 is driven by a driving assembly 4 so that it can move away from or approach the forging assembly.

[0026] A bracket 6 with an inner cavity is fixed on the inner wall of the protective plate 5, and a plurality of nozzles 7 connected to its inner cavity are fixed on the bracket 6. A release agent box 12 is fixed on the forging machine 1, and a delivery pump is provided inside the release agent box 12. The delivery pump is connected to the inner cavity of the bracket 6 through a hose 10.

[0027] Aluminum alloy flanges need to be forged during the processing process. In order to avoid sticking between the high-temperature flange and the forging die, a release material is sprayed into the die cavity of the forging die during the forging process. Among them, the release agent is widely used as a new type of high-efficiency lubricating release material. Since the forging process requires manual operation, and the release agent exists in powder form, it is easy to be inhaled by workers during the spraying process and come into contact with the workers' skin, causing harm to the workers' health.

[0028] In this solution, after the upper mold 2 and the lower mold 3 are opened, that is, when it is necessary to spray the release agent on the inner ends of the upper mold 2 and the lower mold 3, the worker can drive a pair of protective plates 5 to approach each other through the driving component 4, and the pair of protective plates 5 can be merged to surround the upper mold 2 and the lower mold 3, and the release agent can be sprayed on the inner ends of the upper mold 2 and the lower mold 3 through the nozzle 7 arranged on the inner side of the protective plate 5. The release agent box 12 is filled with release agent, and the delivery pump inside the release agent box 12 is responsible for delivering the release agent to the bracket 6 through the hose 10, and finally spraying it out through multiple nozzles 7.

[0029] By setting up a pair of protective plates 5, the periphery between the upper mold 2 and the lower mold 3 can be effectively wrapped, so that during the spraying process of the release agent, the overflow of the release agent can be greatly reduced, thereby effectively reducing the contact between the workers and the release agent, and protecting the health of the workers. At the same time, due to the blocking of the pair of protective plates 5, the sprayed release agent is gathered on the inner side of the pair of protective plates 5, so that most of the release agent can be attached to the inner ends of the upper mold 2 and the lower mold 3, thereby improving the utilization rate of the release agent and reducing waste.

[0030] The two protective plates 5 are semi-annular structures that can be interlocked, and the inner diameter of the interlocking structure is larger than the diameter of the forging assembly. The height of the protective plates 5 is larger than the distance between the upper die 2 and the lower die 3. The inner diameter of the protective plates 5 is larger than the diameter of the upper die 2 and the lower die 3, ensuring that the pair of protective plates 5 can surround the upper die 2 and the lower die 3 after being combined. The height of the protective plates 5 is larger than the distance between the upper die 2 and the lower die 3, ensuring that after the pair of protective plates 5 surround the upper die 2 and the lower die 3, no large gap will be left on the upper and lower sides, thereby reducing the overflow of the release agent.

[0031] like Figure 3 As shown, the drive assembly 4 includes a servo motor 41 and a bidirectional screw 42 driven by the servo motor 41. The bidirectional screw 42 is rotatably connected to the frame of the forging press 1. Each end of the bidirectional screw 42 is provided with a mounting block 8 threadedly matched with the threaded sleeve 9. The two mounting blocks 8 are respectively fixed to the protective plates 5 on both sides. The drive assembly 4 also includes a limit rod 43 arranged parallel to the bidirectional screw 42 and fixed to the frame of the forging press 1. The two mounting blocks 8 are slidably connected to the limit rod 43.

[0032] When the user starts the servo motor 41, the bidirectional screw rod 42 can be driven to rotate. Under the action of a pair of screw sleeves 9, a pair of mounting blocks 8 can be driven to move synchronously in the direction of approaching or moving away from each other. By changing the rotation direction of the servo motor 41, the opening and closing of a pair of protective plates 5 can be controlled. The mounting block 8 slides on the limit rod 43 during the movement, ensuring the stability of the movement of the mounting block 8. The hose 10 can change its shape as the mounting block 8 moves, ensuring that the release agent in the release agent box 12 can be smoothly introduced into the bracket 6 through the hose 10.

[0033] The multiple nozzles 7 are arranged in two rows, one above the other, on the bracket 6, with the two rows of nozzles 7 tilted in the vertical direction. After the pair of protective plates 5 are combined, the pair of brackets 6 can also be combined, forming a complete ring. The multiple nozzles 7 are arranged in an equidistant pattern, and the two rows of nozzles 7 can evenly spray the release agent onto the inner ends of the upper mold 2 and the lower mold 3, ensuring spray coverage.

[0034] like Figure 4-Figure 5 As shown, a switch 13 electrically connected to the delivery pump is installed on the release agent box 12, and a spring 14 is sleeved on the switch 13. The two ends of the spring 14 are respectively connected to the release agent box 12 and the spring 14. A pressing block 11 is fixed on the mounting block 8. When the two protective plates 5 are driven by the driving assembly 4 to engage with each other, the pressing block 11 contacts the switch 13 and generates a force on the spring 14.

[0035] When the switch 13 is released, the spring 14 is squeezed, and when the switch 13 is released, the switch 13 is reset by the elastic force of the spring 14, so that the contacts are separated, the circuit is disconnected, and the delivery pump stops. When a pair of protective plates 5 are merged, the pressing block 11 on one of the mounting blocks 8 abuts against the switch 13 and pushes it into the release agent box 12, so that the delivery pump starts and sprays the release agent. When the pair of protective plates 5 are separated, the pressing block 11 is separated from the switch 13, the delivery pump is turned off, and the release agent stops being released. With this arrangement, the release time of the release agent can be controlled to ensure that the release agent can only be released when the pair of protective plates 5 are merged, thereby reducing the overflow of the release agent and the waste of the release agent.

[0036] Working principle:

[0037] After the upper mold 2 and the lower mold 3 are opened, the user starts the servo motor 41 to drive the bidirectional screw 42 to rotate. Under the action of a pair of screw sleeves 9, the pair of mounting blocks 8 are driven to move synchronously in the direction of approaching each other. The hose 10 changes its shape following the movement of the mounting block 8. As the mounting block 8 moves, a pair of protective plates 5 merge and surround the outside of the upper mold 2 and the lower mold 3. At this time, the pressing block 11 abuts against the switch 13 and pushes it into the release agent box 12, so that the delivery pump is started. The delivery pump introduces the release agent inside the release agent box 12 into the bracket 6 through the hose 10, and finally sprays it to the inner end of the upper mold 2 and the lower mold 3 through multiple nozzles 7.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
