Description

Technical Field

[0001] This utility model relates to the technical field of hot stamping devices, specifically a hot stamping device for copper parts used in the production of refrigerant distributors. Background Technology

[0002] A refrigerant distributor is a component located at the front end of a refrigerant unit. It is generally made of copper alloy. Existing distributors are usually made by turning and drilling holes in copper rods. Turning requires removing excess material, which is wasteful in terms of processing and cost. Hot stamping forming technology, on the other hand, is a technology based on heating and softening metal material, and then stamping it at high speed through a die to form a product with a certain shape and structure. It is widely used in the field of machining and can effectively solve the problem of raw material manufacturing for copper parts of distributors.

[0003] Therefore, the design of a hot stamping device for the stamping of copper parts for distributors is essential. However, existing automatic and semi-automatic hot stamping devices generally include a feeding assembly, which heats the raw material at its end. The material is then transferred to the stamping assembly via a power structure, where it is quickly stamped and then removed. However, in existing technologies, improper material movement is particularly prone to occur during the process of feeding the raw material into the die, leading to inaccurate material positioning and ultimately resulting in defects in the stamped product. Therefore, the design of the copper parts for distributors needs to be improved based on their structure. Utility Model Content

[0004] This application provides a hot stamping apparatus for copper parts in the production of refrigerant distributors. By improving the existing hot stamping equipment and its structure, it enables more convenient and automated stamping of copper parts used in the production of refrigerant distributors.

[0005] The hot stamping apparatus for copper parts in the production of refrigerant distributors provided in this application includes a feeding assembly and a stamping assembly. The feeding assembly is used to pick out pre-cut copper segments and remove raw materials that are not up to standard in length or are not placed correctly. It includes a vibrating feeder, a conveyor track, and a feeding arm. The conveyor track is also equipped with a rejection structure. The feeding assembly also includes a receiving hopper with a heat treatment device. The stamping assembly includes a punch, a pressing die, and an unloading arm for unloading the stamped copper parts. The pressing die is fixedly installed below the end of the conveyor track. The stamping assembly also includes a power assembly and a connecting arm linked to the power assembly. The connecting arm is used to drive the receiving hopper to swing above the pressing die. The feeding arm is used to clamp the copper segment at the end of the conveyor track and put it into the receiving hopper.

[0006] As a further provision of the above scheme, the punch and the die are arranged opposite each other in the vertical direction, the die is provided with a material groove, and the heat treatment device is located at the bottom of the receiving hopper for heating and softening the copper segment.

[0007] As a further provision of the above scheme, the drive unit of the receiving hopper is also provided with a baffle plate, the baffle plate swings coaxially with the receiving hopper, and the baffle plate is provided with a return coil spring to drive the relative swing of the receiving hopper. The baffle plate is provided with a baffle groove, the receiving hopper is also provided with a linkage rod provided relative to the baffle groove, the baffle plate is also provided with a limit rod, and the drive unit is provided with a limit post.

[0008] As a further provision of the above scheme, the heat treatment device includes an induction coil, which is embedded in a receiving hopper made of ceramic material, and the heat treatment device is equipped with a tactile switch, which is located on the drive unit of the receiving hopper. The swinging of the receiving hopper triggers the tactile switch to start the heat treatment device to heat the copper segment.

[0009] As a further provision of the above scheme, one end of the conveying track is located near the feeding arm at the other end of the vibrating feeder, and the rejection structure includes a dropping chute, a short chute, and a long guide plate for rejecting copper segments that are not up to standard or are incorrectly oriented and are conveyed by the vibrating feeder on the conveying track.

[0010] As a further feature of the above scheme, a vibration motor is also connected to the outside of the receiving hopper. The vibration motor is used to generate vibration to shake the copper segments that are picked up by the feeding arm and dropped into the receiving hopper, so that they fall into the bottom of the receiving hopper based on the vibration.

[0011] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0012] 1) The device of this utility model uses copper rods to heat-treat and stamp the copper parts of the distributor, which can reduce the waste of turning materials and avoid the problems of high material and processing costs;

[0013] 2) Secondly, the copper parts produced by the scheme of this embodiment, which uses continuous casting rod + rolling + hot forging, have high density and high strength, and the structure of the copper parts is more convenient for subsequent finished product processing.

[0029] like Figures 1-8 The present invention discloses a hot stamping device for copper parts in the production of refrigerant distributors. The hot stamping device includes a feeding assembly 1 and a stamping assembly 3. The feeding assembly 1 is used to pick out pre-cut copper segments 8, removing those that are of unacceptable length or improperly placed. It includes a vibrating feeder 2, a conveying track 21, and a feeding arm 22. The conveying track 21 is also equipped with a rejection structure 23. The feeding assembly 1 also includes a receiving hopper 24 with a heat treatment device 25. The stamping assembly 3 includes a die 31 for stamping the copper segment 8, a pressing die 32, and a unloading arm 33 for unloading the stamped copper part 9. The pressing die 32 is fixedly installed below the end of the conveying track 21. The stamping assembly 3 also includes a power assembly 5 and a connecting arm 51 that is linked to the power assembly 5. The connecting arm 51 is used to drive the receiving hopper 24 to swing above the pressing die 32. The loading arm 22 is used to clamp the copper segment 8 at the end of the conveying track 21 and put it into the receiving hopper 24.

[0030] As a further provision of the above scheme, the punching die 31 and the pressing die 32 are arranged opposite each other in the vertical direction, the pressing die 32 is provided with a material groove 321, and the heat treatment device 25 is located at the bottom of the receiving hopper 24 for heating and softening the copper segment 8.

[0031] As a further provision of the above scheme, the drive unit of the receiving hopper 24 is also provided with a baffle plate 241. The baffle plate 241 swings coaxially with the receiving hopper 24, and a return coil spring is provided on the baffle plate 241 to drive the relative swinging of the receiving hopper 24. The baffle plate 241 is provided with a baffle groove 243. The receiving hopper 24 is also provided with a linkage rod 242 relative to the baffle groove 243. The baffle plate 241 is also provided with a limit rod 244, and the drive unit is provided with a limit post 245.

[0032] As a further provision of the above scheme, the heat treatment device 25 includes an induction coil 251, which is embedded in the receiving hopper 24 made of ceramic material. The heat treatment device 25 is equipped with a tactile switch, which is located on the drive unit of the receiving hopper 24. The swinging of the receiving hopper 24 triggers the tactile switch to start the heat treatment device 25 to heat the copper segment 8.

[0033] As a further provision of the above scheme, one end of the conveying track 21 is located near the vibrating feeder 2 and the other end is close to the feeding arm 22. The rejection structure 23 includes a dropping trough 42, a short material trough 43, and a long material guide plate 44 for rejecting copper segments 8 that are not up to standard or are incorrectly oriented and are conveyed by the vibrating feeder 2 on the conveying track 21.

[0034] As a further feature of the above scheme, a vibration motor is also connected to the outside of the receiving hopper 24. The vibration motor is used to generate vibration to shake the copper segment 8 that is picked up by the feeding arm 22 and dropped into the receiving hopper 24, so that it adjusts its orientation based on the vibration and falls into the bottom of the receiving hopper 24.

[0035] Example: Figure 1 The embodiment shown includes a hot stamping device for copper parts used in the production of refrigerant distributors. The hot stamping device mainly comprises the main structure of the equipment: a feeding assembly 1 and a stamping assembly 3, as shown below. Figures 1-2 The feeding assembly 1 shown is used to pick out materials that are not of the correct length or are not placed correctly from the pre-cut copper segments 8. It includes a vibrating feeder 2, a conveying track 21, and a feeding arm 22.

[0036] like Figures 6-7 The conveying track 21 shown in this embodiment is also provided with a rejection structure 23. The rejection structure 23 includes a dropping chute 42, a short chute 43, and a long guide plate 44 for rejecting copper segments 8 that are not up to standard or are incorrectly oriented and are conveyed on the conveying track 21 by the vibrating feeder 2. As described above, the conveying track 21 of this embodiment is provided with several rejection components, such as... Figures 6-7The material drop chute 42 shown is located on both sides of the bottom of the conveyor track 21, with dimensions smaller than the height and diameter of the copper segment 8. Calculations based on practical applications show that this design prevents the copper segment 8 from falling off when it is upright, while preventing it from rolling off the bottom of the conveyor track 21 when it is tilted. A return box is located below this point on the conveyor track 21, allowing the dropped material to be re-loaded into the vibrating feeder 2 for further feeding. The short material chute 43 and the long material guide plate 44 operate on similar principles. 43 is a notch set on the side of the conveying track 21. The size of the notch is slightly smaller than that of the copper segment 8. When the copper segment 8 with a size smaller than the set length is passed, it will fall through the notch. The long material guide plate 44 is an inclined protrusion set on the top of the conveying track 21. The inclined protrusion extends outward. When it encounters a copper segment 8 with a size longer than the set length, it guides it to fall. The raw materials rejected by both the short material trough 43 and the long material guide plate 44 are all non-compliant raw materials. After falling into the waste bin, they are recycled by the staff.

[0037] Furthermore, the feeding assembly 1 in this embodiment also includes a receiving hopper 24 with a heat treatment device 25. The stamping assembly 3 also includes a power assembly 5 and a connecting arm 51 linked to the power assembly 5. The connecting arm 51 is used to drive the receiving hopper 24 to swing above the die 32. The feeding arm 22 is used to clamp the copper segment 8 at the end of the conveying track 21 and put it into the receiving hopper 24. The driving unit of the receiving hopper 24 is also provided with a baffle plate 241. The baffle plate 241 swings coaxially with the receiving hopper 24, and the baffle plate 241 is provided with a return coil spring to drive the relative swing of the receiving hopper 24. The material plate 241 is provided with a baffle groove 243, and the receiving hopper 24 is also provided with a linkage rod 242 positioned opposite the baffle groove 243. The baffle plate 241 is also provided with a limit rod 244, and the drive unit is provided with a limit post 245. The heat treatment device 25 includes an induction coil 251, which is embedded in the receiving hopper 24 made of ceramic material. The heat treatment device 25 is also provided with a tactile switch, which is located on the drive unit of the receiving hopper 24. The swinging of the receiving hopper 24 triggers the tactile switch to start the heat treatment device 25 to heat the copper segment 8. The above structure is combined with the attached... Figure 5 and Figure 8As shown, the distinctive receiving hopper 24 structure of this embodiment includes a receiving hopper 24 body and a baffle plate 241 that are oscillating relative to the pressing mold 32. Notably, the baffle plate 241 is located at the bottom of the receiving hopper 24 and is used to close the opening at the bottom of the receiving hopper 24. Furthermore, a linkage design is provided between the receiving hopper 24 and the baffle plate 241, including a baffle groove 243 and a linkage rod 242. A limiting rod 244 and a limiting post 245 are provided between the drive unit fixed relative to the receiving hopper 24 and the baffle plate 241 to achieve limiting. It is worth noting that the structural principle is as follows: A return coil spring is provided on the baffle plate 241, with its two ends connected to the drive unit and the baffle plate 241 respectively. When the drive unit drives the receiving hopper 24 to rotate, the drive unit itself remains fixed relative to the device. The baffle plate 241, based on the elastic force of the return coil spring, swings relative to the device. The swing direction is the same as the direction in which the receiving hopper 24 swings towards the pressing mold 32. However, due to the limiting rod 244 provided on the baffle plate 241 and the limiting post 245 extending from the drive unit, its swing angle is limited, and it can only swing to a certain distance. Figure 8 At the angle shown in a, the bottom opening of the receiving hopper 24 faces the die 32, while the baffle plate 241 is restricted to one side of the material outlet of the die 32.

[0038] and Figure 8 b refers to the reset swing state of the receiving hopper 24 under the drive of the drive unit. At this time, the receiving hopper 24 resets and swings, but since the drive unit does not form a driving relationship with the baffle plate 241, the receiving hopper 24 swings to the state shown in Figure 24. Figure 8 At the angle shown in b, the baffle plate 241 remains stationary. As it continues to swing, the connecting rod 242 abuts against the stop groove 243, causing the receiving hopper 24 to drive the baffle plate 241 to swing in conjunction. Firstly, it moves away from the position between the punch 31 and the die 32, ensuring that it does not obstruct the two when they are closed. Secondly, the swinging motion compresses the reset coil spring. At the same time, the baffle plate 241 is located below the receiving hopper 24, closing the receiving hopper 24. After swinging to a certain position, the loading arm 22 clamps the copper segment 8 and places it into the receiving hopper 24, where it falls vertically into the heating area at the bottom.

[0039] Furthermore, the stamping assembly 3 includes a punch 31 for stamping the copper segment 8, a pressing die 32, and a unloading arm 33 for unloading the stamped copper part 9. The pressing die 32 is fixedly installed below the end of the conveying track 21. The punch 31 and the pressing die 32 are arranged opposite each other in the vertical direction. The pressing die 32 is provided with a material groove 321. The heat treatment device 25 is located at the bottom of the receiving hopper 24 and is used to heat and soften the copper segment 8.

[0040] As described above and in conjunction with the attached diagram, when the loading arm 22 clamps the copper segment 8 and places it into the receiving hopper 24, the punch 31 and pressing die 32 complete the die closing and pressing process and then perform die separation and reset. At this time, the unloading arm 33 moves to remove the copper part 9 from the pressing die 32. Subsequently, the drive unit drives the receiving hopper 24 to swing. During the swing, a tactile switch is triggered to start the heat treatment device 25. The induction coil 251 heats the copper segment 8 in the middle until the receiving hopper 24 moves to... Figure 8 In state a, copper segment 8 falls from the receiving hopper 24 with its bottom opening into the die 32 for stamping and die closing.

[0041] As a further feature of the above scheme, a vibration motor is also connected to the outside of the receiving hopper 24. The vibration motor is used to generate vibration to shake the copper segment 8 that is picked up by the feeding arm 22 and dropped into the receiving hopper 24, so that it adjusts its orientation based on the vibration and falls into the bottom of the receiving hopper 24.

[0042] The working steps of the device in this embodiment include a vibratory feeder 2 that continuously vibrates to feed materials. The vibratory feeder 2 refers to the vibratory feeder structure of the prior art, which can transport materials one by one into the conveying track 21. Based on the rejection structure 23 set on it, copper segments 8 that do not meet the size requirements or are incorrectly oriented are rejected. The rejected raw materials are piled up on one side of the conveying track 21, and are clamped one by one by the feeding arm 22 and fed into the receiving hopper 24. As mentioned above, the receiving hopper 24 is funnel-shaped, and a vibration motor is connected to the upper middle part. Under the vibration of the vibration motor, the copper segments 8 are kept alive. The movement effectively prevents the raw material from being stuck horizontally at the top of the funnel-shaped receiving hopper 24. When the raw material falls to the bottom, the equipment is in the stamping to mold separation stage. After the stamping die rises, the unloading arm 33 unloads the material, and at the same time, the receiving hopper 24 starts feeding. Based on the light touch switch set on the swing stroke of the receiving hopper 24, the heat treatment device 25 is triggered to heat and soften the copper section 8 until the receiving hopper 24 rotates to release the baffle plate 241 at the bottom opening, so that the raw material falls naturally and accurately into the pressing die 32. Then, the receiving hopper 24 resets, and the stamping assembly 3 closes the mold and performs a cycle of stamping.

[0043] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
