Description

Technical Field

[0001] This invention belongs to the field of equipment manufacturing technology, and in particular relates to a vertical solid-liquid composite forging equipment. Background Technology

[0002] The materials used for smartphone frames are constantly evolving, including aluminum, stainless steel, and titanium alloys. Aluminum is easy to cut, has low processing difficulty, high efficiency, and low cost. Steel and titanium are difficult to cut, the cutting tools wear out easily, and the processing efficiency is much lower than that of aluminum. However, they are much more expensive, but they are stronger. To meet the requirements of high strength, high processing efficiency, and low cost for the appearance of the phone frame, stainless steel and titanium alloys are used for the outer surface of the frame, while the inner surface uses aluminum alloy, which is easier to cut.

[0003] The traditional method is to use composite forging + CNC: the frame is divided into several parts, and each part is made of composite raw materials by rolling (the outer side of the outer frame is made of titanium or stainless steel, and the inner side is made of aluminum), then forging process + CNC machining is used, the middle frame is processed separately, and finally the outer frame and the middle frame are combined and welded together. Secondly, the entire component is made of all-aluminum material and machined directly by CNC, but the strength of this all-aluminum material is far less than that of titanium material. Third, it is forged from all titanium or all stainless steel and then CNC machined. This process involves a very large amount of processing and is extremely costly, so it is rarely used in the industry. Therefore, a method to shorten the process, reduce costs, and increase strength is to integrate the components together as a whole, which has become a new process requirement. The conventional vertical hydraulic press equipment cannot meet the forming requirements of this process. Conventional vertical hydraulic presses can only forge solid metals, which limits the forging range and thus affects the application scope of vertical hydraulic presses. Summary of the Invention

[0004] This invention addresses the problem that existing vertical hydraulic presses can only forge solid metals, thus limiting their forging range and impacting their application scope. The following technical solution is proposed: A vertical solid-liquid composite forging device includes: a lower machine cover, a lower machine foot installed on the outer side of the bottom end of the lower machine cover, a lower crossbeam fixedly installed on the top end of the lower machine cover, a lower worktable installed above the lower crossbeam, an upper working slide vertically and movably connected above the lower worktable, molds installed between the opposite surfaces of the upper working slide and the lower worktable, a forging-extrusion-cooling composite system vertically and movably connected inside the lower crossbeam, and a forging head installed at the top end of the forging-extrusion-cooling composite system.

[0005] As a preferred embodiment of the above technical solution, mold alignment rods are symmetrically embedded and installed at the top of the lower worktable, the mold on the lower worktable is sleeved on the outside of the mold alignment rods, and a slot is opened in the middle of the mold on the lower worktable.

[0006] As a preferred embodiment of the above technical solution, each of the four corners of the top of the lower worktable is embedded with a main guide column, the top of the main guide column is snapped with an upper crossbeam, the bottom of the upper crossbeam is fixedly mounted with an upper hydraulic cylinder, the movable end of the upper hydraulic cylinder is fixedly mounted with an upper working slider and the upper working slider is slidably connected to the main guide column, the upper working slider is fixedly connected to the mold, and limit plates are symmetrically fixedly mounted on both sides of the mold under the upper working slider.

[0007] As a preferred embodiment of the above technical solution, a lower hydraulic cylinder is fixedly installed inside the lower machine cover, a limit bearing plate is fixedly installed on the movable end of the lower hydraulic cylinder, a lower push rod is installed on the top of the limit bearing plate, and the forging and extrusion cooling composite system is installed inside the lower push rod.

[0008] As a preferred embodiment of the above technical solution, a connecting ring is provided between the forging and cooling composite system and the forging head for connecting and fixing the two. Lower guide posts are connected through the four corners of the top of the limiting bearing plate, and the top and bottom of the lower guide posts are fixedly connected to the lower machine cover.

[0009] As a preferred embodiment of the above technical solution, the forging and extrusion cooling composite system includes a support rod fixedly installed on the top of the limiting bearing plate, a three-way valve fixedly installed inside the support rod, and a connecting pipe fixedly installed on the top of the three-way valve.

[0010] As a preferred embodiment of the above technical solution, a drainage cover is fitted on the top of the outer surface of the connecting pipe, an installation strip is fixedly installed on the outside of the drainage cover, and the installation strip is fixedly connected to the inner wall of the support rod. Multiple support strips are fixedly installed circumferentially on the inner wall of the drainage cover, and the same horn cover is installed between the multiple support strips.

[0011] As a preferred embodiment of the above technical solution, a partition is fixedly installed inside the horn cover, a baffle is rotatably connected to the top of the partition via a shaft, a blade is connected to the bottom of the partition via a shaft, a water inlet channel is provided on the outside of the support rod corresponding to one of the liquid inlets of the three-way valve, and a water outlet channel is provided on the top of the outer surface of the support rod.

[0012] As a preferred embodiment of the above technical solution, the inner wall of the support rod is provided with a storage cavity, and the distance between the storage cavity and the outer side of the connecting pipe is one centimeter. Both the partition and the baffle are provided with water outlet holes.

[0013] The beneficial effects of this invention are as follows: (1) It solves the limitation that conventional vertical forging equipment can only forge solid materials, and can forge solid-liquid composite forming materials. Furthermore, the parts of this equipment not only participate in forging and forming, but also have a cooling function, and are integrated into a forging and cooling composite system with dual functions. (2) The “center + outer side” dual-path cooling design is adopted. The coolant eliminates the local hot spots of the forging head and achieves uniform heat dissipation. This can not only effectively prevent the workpiece from structural defects and internal stress caused by uneven cooling, but also significantly reduce the working temperature of the forging head and mold, slow down thermal fatigue, thereby extending the service life of expensive molds by several times and ensuring the consistency of product quality between batches. (3) It can effectively prevent coolant from stagnating in low flow rate areas for a long time, greatly reducing the risk of scale and impurity deposition, and reducing maintenance frequency and downtime. At the same time, the on-demand flow mode also avoids the waste of pumping energy and achieves energy-saving operation. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] Example 1 This invention provides a vertical solid-liquid composite forging device, such as... Figures 1 to 4 As shown, it includes: a lower machine cover 108, a lower machine foot 111 installed on the outer side of the bottom end of the lower machine cover 108, a lower crossbeam 107 fixedly installed on the top end of the lower machine cover 108, a lower worktable 106 installed above the lower crossbeam 107, an upper working slide block 103 vertically and movably connected above the lower worktable 106, a mold 117 installed between the opposite surfaces of the upper working slide block 103 and the lower worktable 106, a forging and cooling composite system 112 vertically and movably connected inside the lower crossbeam 107, and a forging head 115 installed at the top end of the forging and cooling composite system 112.

[0018] In the existing technology, vertical hydraulic presses can only forge solid metals, which limits the forging range and thus affects the application range of vertical hydraulic presses.

[0019] This application overcomes the limitation that conventional vertical forging equipment can only forge solid materials, and can forge solid-liquid composite molding materials; Furthermore, the parts of this equipment not only participate in forging and forming but also have a cooling function, integrating into a forging and cooling composite system with dual functions.

[0020] In use, the part is placed above the mold 117 located on the lower worktable 106, and then the upper working slider 103 slides downward. At this time, the upper working slider 103 drives the upper mold 117 to press the product on the lower worktable 106. Then, the forging and cooling composite system 112 is moved vertically. At this time, the forging and cooling composite system 112 drives the forging head 115 to move along the middle area of ​​the lower mold 117, thereby forging the pressed product. At the same time, the coolant inside the forging and cooling composite system 112 flows to cool the product.

[0021] Specifically, multiple lower machine feet 111 are symmetrically welded to the outer side of the bottom end of the lower machine cover 108, specifically four in this application. A lower crossbeam 107 is welded to the top of the lower machine cover 108, and a lower worktable 106 is welded to the top of the lower crossbeam 107. A mold alignment rod 105 is symmetrically embedded in the top of the lower worktable 106. The lower worktable 106 has four main guide columns 104 embedded at its top corners. A single upper crossbeam 101 is snapped onto the top of the outer surface of each of the four main guide columns 104. An upper hydraulic cylinder 102 is screwed onto the middle of the bottom of the upper crossbeam 101. An upper working slider 103 is screwed onto the movable end of the upper hydraulic cylinder 102, and the upper working slider 103 is slidably connected to the main guide columns 104. Molds 117 are installed between the upper working slider 103 and the opposite surfaces of the lower worktable 106. The molds 117 on the lower worktable 106 are fitted onto the outside of the mold alignment rod 105. A slot is formed in the middle of the molds 117 on the lower worktable 106, and a matching groove is formed in the middle of the lower worktable 106. The upper working slider 103 and the molds 117 are fixedly connected by screws. The molds 117 under the upper working slider 103 are symmetrically fixed on both sides. A limit plate is installed, and the distance between the two limit plates is equal to the maximum length of the mold 117 located on the lower worktable 106. A lower hydraulic cylinder 109 is fixedly installed inside the lower machine cover 108 by screws. A limit support plate 113 is fixedly installed at the movable end of the lower hydraulic cylinder 109 by screws. A lower push rod 110 is installed at the top of the limit support plate 113 by screws. A forging and cooling composite system 112 is fixedly installed inside the lower push rod 110 at the top of the limit support plate 113. A forging head 115 is installed at the top of the forging and cooling composite system 112. A connecting ring 116 is snapped between the forging and cooling composite system 112 and the forging head 115 for connection and fixation between the two. Lower guide posts 114 are connected through the four corners of the top of the limit support plate 113. The top and bottom ends of the lower guide posts 114 are fixedly connected to the inner wall of the lower machine cover 108.

[0022] To achieve the cooling of the product and forging head 115 during forging in the above embodiments, the following solution is provided: Figure 3 and Figure 4As shown, the forging and extrusion cooling composite system 112 includes a support rod 1121 fixedly installed on the top of the limiting support plate 113. A three-way valve 1122 is fixedly installed inside the support rod 1121. A connecting pipe 1123 is fixedly installed on the top of the three-way valve 1122. A flow guide shroud 11212 is sleeved on the top of the outer surface of the connecting pipe 1123. An installation strip 1125 is fixedly installed on the outer side of the flow guide shroud 11212, and the installation strip 1125 is fixedly connected to the inner wall of the support rod 1121. Multiple support strips 1124 are fixedly installed circumferentially on the inner wall of the flow guide shroud 11212, and the multiple support strips 1124 are connected by the same... The speaker cover 1126 has a partition 1127 fixedly installed inside it. The top of the partition 1127 is rotatably connected to a baffle 1128 via a shaft. The bottom of the partition 1127 is connected to a blade 1129 via a shaft. The outer side of the support rod 1121 has a water inlet channel 11210 corresponding to one of the liquid inlets of the three-way valve 1122. The top of the outer surface of the support rod 1121 has a water outlet channel 11211. The inner wall of the support rod 1121 has a receiving cavity, and the distance between the receiving cavity and the outer side of the connecting pipe 1123 is one centimeter. Both the partition 1127 and the baffle 1128 have water outlet holes inside.

[0023] In use, the coolant enters the three-way valve 1122 through the inlet channel 11210. Then, it enters the connecting pipe 1123 through the three-way valve 1122. The coolant then flows through the connecting pipe 1123 into the gap between the inner wall of the flow guide shroud 11212 and the outer side of the horn cover 1126 and the middle of the horn cover 1126. The flowing coolant then enters the middle and outer side of the bottom of the forging head 115 to form a uniform cooling effect. Then, it enters the outlet channel 11211 through the receiving cavity and finally exits through the outlet channel 11211. Furthermore, the coolant flowing inside the horn cover 1126 contacts the blades 1129, causing the blades 1129 to rotate. When the blades 1129 rotate, they drive the baffle 1128 to rotate. When the baffle 1128 rotates, it intersects with the water outlet holes of the partition 1127, thereby changing the flow speed of the coolant inside the horn cover 1126. The flow speed of the coolant outside the horn cover 1126 increases. By changing the flow speed, the change in flow speed can prevent the coolant from stagnating at low speed for a long time, reduce the deposition of scale or impurities, and maintain the cleanliness of the system.

[0024] Specifically, a support rod 1121 is screwed onto the top of the limiting plate 113, and the support rod 1121 is located inside the lower push rod 110 and coaxially arranged. A three-way valve 1122 is fixedly installed inside the support rod 1121, and a connecting pipe 1123 communicating with it is fixedly installed on the top of the three-way valve 1122. A drainage cover 11212 is sleeved on the top of the outer surface of the connecting pipe 1123. Multiple mounting strips 1125 are welded to the outer surface of the drainage cover 11212, and the multiple mounting strips 1125 are fixedly connected to the inner wall of the support rod 1121 with screws. Multiple support strips 1124 are fixedly installed circumferentially on the inner wall of the drainage cover 11212, and the same horn cover 1126 is installed between the multiple support strips 1124. The horn cover 1126 and the drainage cover are connected. The components 11212 are fixed together by a support bar 1124. A partition 1127 is welded and installed inside the horn cover 1126. A shaft is rotatably connected inside the partition 1127. A baffle 1128 is fixedly installed on the outer surface of the shaft at the top of the partition 1127 by a key. Water outlet holes are opened inside both the partition 1127 and the baffle 1128. A blade 1129 is connected to the outer surface of the shaft at the bottom of the partition 1127 by a key. A water inlet channel 11210 is opened on the outer side of the support rod 1121 corresponding to one of the liquid inlets of the three-way valve 1122. A water outlet channel 11211 is opened on the top of the outer surface of the support rod 1121. A receiving cavity is opened on the inner wall of the support rod 1121, and the distance between the receiving cavity and the outer side of the connecting pipe 1123 is one centimeter, which is used for the discharge flow of coolant.

[0025] Working principle: Before the device is put into use, the upper hydraulic cylinder 102 is started, which drives the upper working slide 103 to rise, so that the upper working slide 103 is in a high position. The upper working slide 103 drives the mold 117 connected to it to move, thereby keeping the mold 117 on the lower worktable 106 in an open state (the position of the mold 117 on the lower worktable 106 is positioned by the mold alignment rod 105). At this time, the forging and extrusion cooling composite system 112 and the forging head 115 are located in the initial position below the lower worktable 106 under the action of the lower hydraulic cylinder 109. At this time, the forging and extrusion cooling composite system 112 is closed. Next, the solid-liquid composite blank (or semi-solid material) is placed in the cavity of the mold 117 on the lower worktable 106. Then, the upper hydraulic cylinder 102 is activated to drive the upper working slider 103 to move downward along the main guide column 104. The mold 117 of the upper working slider 103 moves downward with the upper working slider 103 and closes with the mold 117 on the lower worktable 106 to perform preliminary pressing of the blank. Next, the lower hydraulic cylinder 109 is activated, which pushes the limiting bearing plate 113 and the forging and cooling composite system 112 installed on it to move upward. The forging and cooling composite system 112 drives the forging head 115 upward through the slot in the middle of the mold 117 on the lower worktable 106 via the connecting ring 116, and enters the mold cavity. The forging head 115 performs axial forging and extrusion on the blank in the closed mold 117 to achieve further densification and forming of the solid-liquid composite material. During the forging and extrusion process, the cooling system is started simultaneously. Coolant is pumped from the outside into the water inlet channel 11210 of the support rod 1121, enters the three-way valve 1122, and is transported upward through the connecting pipe 1123 into the internal space of the diversion shroud 11212. At this time, it flows upward along the annular gap between the diversion shroud 11212 and the outer side of the horn shroud 1126, which is the outer flow path. It flows upward through the central area of ​​the horn shroud 1126, through the space between the baffle 1127 and the baffle 1128 inside, which is the central flow path. The two coolant paths eventually merge and cover the bottom working surface of the forging head 115 to achieve uniform forced cooling. The coolant flowing through the central area of ​​the horn cover 1126 impacts the blades 1129, driving them to rotate. The blades 1129 drive the upper baffle 1128 to rotate via the shaft, causing the water outlet on the baffle 1128 to be relatively misaligned with the water outlet on the partition 1127. When enhanced cooling is required, the resistance of the central flow path increases, and more coolant is guided to the outer flow path, improving the cooling intensity on the outside of the forging head 115. The adjustment process does not require external control and is driven by the fluid flow itself, achieving dynamic response. After absorbing heat, the coolant flows downward along the receiving cavity on the inner wall of the support rod 1121, and is finally discharged from the system through the water outlet channel 11211, entering the external heat exchange device for cooling and then circulating. The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
