Description

Technical Field

[0001] This application relates to the field of cold extrusion press technology, and in particular to a fully automatic cold extrusion capping device. Background Technology

[0002] A cold extrusion press, also commonly referred to as a cold welding machine or cold pressure welding machine, is a solid-state welding device that applies enormous pressure at room temperature (without external heating) to cause plastic deformation of the metal materials being joined, thereby achieving interatomic bonding at the contact interface and forming a strong welded joint.

[0003] For existing equipment, when the base and shell of a product are extruded into one piece, the base is usually placed on the mold first by hand, and then the shell is placed on the base. The base and shell are then extruded into one piece by pressing and sealing the mold. Then, the base and shell are removed manually and repositioned. However, this manual method is inefficient and reduces the working efficiency of the equipment. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a fully automatic cold extrusion capping device, which solves the problem of low efficiency and reduced working efficiency of the device due to manual methods.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a fully automatic cold extrusion capping device, including a support frame, an oven mounted on the support frame, several trays placed inside the oven and divided into two groups, one group of trays for placing several bases and the other group of trays for placing several outer shells, a dragging mechanism for pulling the trays out of the oven mounted on the support frame, a cold extrusion mold for pressing the bases and outer shells into one piece mounted on the support frame, and a sliding mechanism for transporting the trays on the dragging mechanism to the compression assembly mounted on the support frame, the sliding mechanism being equipped with a clamping mechanism for clamping the bases and outer shells on the trays onto the cold extrusion mold.

[0006] Furthermore, the bottom surface of the tray has four holes arranged in a straight line.

The dragging mechanism also includes a second motor and a first gear. The second motor is located on the top surface of the sliding plate, with its output end pointing vertically downwards and penetrating the top surface of the sliding plate. The output end of the second motor is fixedly connected to the end face of the first gear, which meshes with the first rack.

[0008] Furthermore, the transverse component includes a baffle, a second slide rail, a third motor, a second gear, and a second rack. The baffle is disposed on the top surface of the slide plate, the second slide rail is disposed on the side of the baffle near the bracket, the bracket is slidably connected to the second slide rail, the third motor is disposed on one side of the bracket, the output end of the third motor passes through one side of the bracket and is fixedly connected to the second gear, and the second rack is disposed on the side of the bracket near the baffle, the second gear meshing with the second rack.

[0009] Furthermore, the sliding mechanism includes a first guide rail and a first sliding block. The first guide rail is fixedly installed on the top surface of the support frame and is perpendicular to the second slide rail. The first sliding block is slidably disposed on the first guide rail and has two placement plates disposed on it, which are used to support the pallet respectively.

[0010] Furthermore, the clamping mechanism includes a pneumatic gripper and a displacement assembly. The displacement assembly is mounted on the support frame and has a drive assembly for driving the pneumatic gripper to move up and down. The displacement assembly is used to drive the pneumatic gripper to move laterally. The pneumatic gripper is mounted on the drive assembly and is located above the two placement plates.

[0011] Furthermore, the displacement component includes a second guide rail and a second slider.

[0013] Furthermore, the cold extrusion die includes a support arm, a support base, a sealing die, and a cylinder. The support arm and the support base are respectively disposed on the top surface of the support frame, the cylinder is disposed on the support arm, and the sealing die is fixedly installed at the output end of the cylinder and located on the top surface of the support base.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. When using the device, the two sets of trays, arranged with the base and the outer shell, are sent into the oven for vacuuming and heating. The oven temperature is 400℃, the vacuum is 1X10E-3Pa, and the working temperature of the carrier tray is 200℃. This completes the pre-treatment process and improves product performance. After heating for the set time, cooling is performed. When the temperature drops to within the required process range, the oven door on the side near the transfer mechanism automatically opens. The transfer mechanism moves in two steps, removing one tray containing the base and one tray containing the outer shell from the oven and placing them on the sliding mechanism. Subsequently, the clamping mechanism sequentially picks up one outer shell and one base from the tray and places them on the cold extrusion die, initiating the compression process to cold extrude the outer shell and base into one piece. After cold extrusion, the clamping mechanism removes the formed workpiece and places it back into the corresponding tray on the sliding mechanism. Repeat the above operation until all bases and shells in both pallets of this batch have been cold-extruded. Once all workpieces on the sliding mechanism are formed, the sliding mechanism moves to a position close to the dragging mechanism, which then moves the two pallets back into the oven in two stages. The oven door is then closed, the oven is cooled, and nitrogen is introduced to complete the post-processing of this batch of workpieces. Finally, the operator opens the oven door and removes the finished pallets, completing the integrated cold extrusion process of the base and shell. Through integrated preheating, multi-station collaborative operation, and cold extrusion, efficient and continuous integrated forming of the base and shell is achieved. Automated pallet handling and workpiece transfer significantly reduce manual intervention and improve production efficiency and process consistency. The use of vacuum heating and nitrogen protection effectively improves the quality of cold extrusion and product performance, and the overall working environment of the equipment can automatically circulate within a high vacuum environment.

[0015] 2. When the device is in operation, the two first motors are first started, driving the corresponding first eccentric wheels to rotate. Simultaneously, in conjunction with the transverse component, the entire support frame moves towards the tray inside the oven. When the pin moves to the position corresponding to the tray's insertion hole, the arc surface of the first eccentric wheel presses against the bottom surface of the L-shaped slider, pushing the L-shaped slider upwards along the support frame, thus allowing the pin to accurately insert into the insertion hole. Subsequently, the transverse component continues to operate, smoothly pulling the tray out of the oven and transferring it to the support frame. During this process, through the continuous operation of the first motors, the periodic rotation of the eccentric wheels, and the coordinated action of the transverse component, the pins can be inserted into different insertion holes sequentially, gradually pulling the tray to complete the transfer. Once the two pins are inserted into their corresponding two insertion holes and the tray is confirmed to be stably placed on the support frame, the first motors and the transverse component stop working, completing the entire tray transfer process. This achieves automated tray handling, improves the stability and positioning accuracy of the transfer process, and effectively enhances the convenience and reliability of equipment operation.

[0016] 3. When the device is in operation, it first activates four electric telescopic rods arranged in a rectangular array, simultaneously adjusting the support base to the preset working height to precisely align it with the tray inside the oven, creating favorable conditions for smooth tray placement and removal. Then, the second motor is activated, driving the first gear to rotate. Through engagement with the first rack fixed to the support base, the gear drives the sliding plate to move smoothly along two first slide rails, thereby causing the lateral movement assembly and support mounted on the sliding plate to move towards or away from the oven. This not only achieves flexible adjustment in the Z-axis direction and precise feeding in the X-axis direction, but also, through the coordinated control of the electric telescopic rods, the first gear, and the first rack transmission mechanism, effectively enhances the positioning accuracy and operational stability of the equipment, significantly improving the automation and ease of operation of the tray transfer process.

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] Example, refer to Figures 1-10 A fully automatic cold extrusion sealing device includes a support frame 1, an oven 2 mounted on the support frame 1, and several trays 21 placed inside the oven 2, which are divided into two groups. One group of trays 21 is used to place several bases, and the other group of trays 21 is used to place several shells. The support frame 1 is provided with a dragging mechanism 3 for pulling the trays 21 out of the oven 2. The support frame 1 is provided with a cold extrusion mold 4 for extruding the bases and shells into one piece. The support frame 1 is provided with a sliding mechanism 5 for transporting the trays 21 on the dragging mechanism 3 to the compression assembly. The sliding mechanism 5 is provided with a clamping mechanism 6 for clamping the bases and shells on the trays 21 onto the cold extrusion mold 4.

[0021] When using the device, two sets of trays 21, with the base and outer shell arranged, are fed into oven 2 for vacuuming and heating. The oven temperature is 400℃, the vacuum is 1X10E-3Pa, and the tray working temperature is 200℃, completing the pre-treatment process and improving product performance. After heating for the set time, cooling is performed; when the temperature drops to within the required process range, the oven door on the side of oven 2 closest to the transfer mechanism 3 automatically opens. The transfer mechanism 3 moves in two steps, removing one tray 21 containing the base and one tray 21 containing the outer shell from oven 2 and placing them on the sliding mechanism 5. Subsequently, the clamping mechanism 6 sequentially picks up an outer shell and a base from the tray 21 and places them on the cold extrusion mold 4, initiating the compression process to cold extrude the outer shell and base into one piece. After cold extrusion, the clamping mechanism 6 removes the formed workpiece and places it back into the corresponding tray 21 on the sliding mechanism 5. Repeat the above operation until all bases and shells in the two trays 21 of this batch have been cold-extruded. After all the workpieces on the sliding mechanism 5 are formed, the sliding mechanism 5 moves to a position close to the dragging mechanism 3, and the dragging mechanism 3 moves the two trays 21 back into the oven 2 in two stages. Then the oven door 2 is closed, cooled, and filled with nitrogen to complete the post-processing of this batch of workpieces. Finally, the operator opens the oven door and takes out the finished trays 21, completing the integrated cold extrusion process of the base and shell. Through integrated preheating treatment, multi-station collaborative operation, and cold extrusion, efficient and continuous integrated forming of the base and shell is achieved; automated tray 21 handling and workpiece transfer significantly reduce manual intervention and improve production efficiency and process consistency; the use of vacuum heating and nitrogen protection processes effectively improves the quality of cold extrusion and product performance, and the overall working environment of the equipment can be automatically circulated in a high vacuum environment.

[0022] The bottom surface of the tray 21 has four insertion holes 211 arranged in a straight line. The dragging mechanism 3 includes a bracket 31, an L-shaped slider 32, a first motor 33, a first eccentric wheel 34, and a pin 35. The top surface of the support frame 1 is provided with a support assembly 11, and the support assembly 11 is provided with a transverse component 12 for driving the bracket 31 to move toward or away from the oven 2. One side of the L-shaped slider 32 is slidably connected to one side of the bracket 31. The first motor 33 is fixedly installed on one side of the support frame 1. The output end of the first motor 33 is fixedly connected to the end face of the first eccentric wheel 34. The arc surface of the first eccentric wheel 34 abuts against the bottom surface of the L-shaped slider 32. The pin 35 is provided on the top surface of the L-shaped slider 32. There are two L-shaped sliders 32 and two pins 35, which correspond one to one. The two L-shaped sliders 32 are respectively provided on opposite sides of the bracket 31, and the top ends of the two pins 35 abut against the two insertion holes 211 of the tray 21.

[0023] When the device is in operation, the two first motors 33 are first started, driving the corresponding first eccentric wheels 34 to rotate. Simultaneously, in conjunction with the transverse component 12, the support 31 moves towards the tray 21 inside the oven 2. When the pin 35 moves to the position corresponding to the insertion hole 211 on the tray 21, the arc surface of the first eccentric wheel 34 presses against the bottom surface of the L-shaped slider 32, pushing the L-shaped slider 32 upwards along the support 31, thus allowing the pin 35 to accurately insert into the insertion hole 211. Subsequently, the transverse component 12 continues to operate, smoothly pulling the tray 21 out of the oven 2 and transferring it onto the support 31. During this process, through the continuous operation of the first motors 33, the periodic rotation of the eccentric wheels, and the coordinated action of the transverse component 12, the pins 35 can be inserted into different insertion holes 211 sequentially, gradually pulling the tray 21 to complete the transfer. When the two pins 35 are inserted into their corresponding two insertion holes 211 and the tray 21 is confirmed to be stably placed on the support 31, the first motors 33 and the transverse component 12 stop working, completing the entire tray 21 transfer process. It realizes automated pallet 21 picking and placing, improves the stability and positioning accuracy of the transfer process, and effectively enhances the convenience and reliability of equipment operation.

[0024] The support assembly 11 includes electrically operated telescopic rods 111, a support base 112, first slide rails 113, first racks 114, and sliding plates 115. Four electrically operated telescopic rods 111 are fixedly connected to the top surface of the support frame 1, forming a rectangular array on the top surface of the support frame 1. The output ends of the four electrically operated telescopic rods 111 are fixedly connected to the bottom surface of the support base 112. Two first slide rails 113 are provided, with the two first slide rails 113 and the first rack 114 respectively located on the top surface of the support base 112. The first rack 114 is located between the two first slide rails 113. The sliding plate 115 is slidably connected to the top surface of the two first slide rails 113. The transverse moving assembly 12 is disposed on the top surface of the sliding plate 115. The dragging mechanism 3 also includes a second motor 36 and a first gear 37. The second motor 36 is disposed on the top surface of the sliding plate 115. The output end of the second motor 36 is vertically downward and penetrates through the top surface of the sliding plate 115. The output end of the second motor 36 is fixedly connected to the end face of the first gear 37. The first gear 37 meshes with the first rack 114.

[0025] When the device is in operation, it first activates four electric telescopic rods arranged in a rectangular array, simultaneously adjusting the support base 112 to a preset working height to precisely align it with the tray 21 inside the oven 2, creating favorable conditions for the smooth handling of the tray 21. Then, the second motor 36 is activated, driving the first gear 37 to rotate. Through engagement with the first rack 114 fixed to the support base 112, the gear 37 drives the sliding plate 115 to move smoothly along the two first slide rails 113, thereby causing the lateral movement assembly 12 and the support 31 mounted on the sliding plate 115 to move towards or away from the oven 2. This not only achieves flexible adjustment in the Z-axis direction and precise feeding in the X-axis direction, but also, through the coordinated control of the electric telescopic rods, the first gear 37, and the first rack 114 transmission mechanism, effectively enhances the positioning accuracy and operational stability of the equipment, significantly improving the automation and ease of operation of the tray 21 transfer process.

[0026] The transverse component 12 includes a baffle 121, a second slide rail 122, a third motor 123, a second gear 124, and a second rack 125. The baffle 121 is disposed on the top surface of the sliding plate 115. The second slide rail 122 is disposed on the side of the baffle 121 near the bracket 31. The bracket 31 is slidably connected to the second slide rail 122. The third motor 123 is disposed on one side of the bracket 31. The output end of the third motor 123 passes through one side of the bracket 31 and is fixedly connected to the second gear 124. The second rack 125 is disposed on the side of the bracket 31 near the baffle 121. The second gear 124 meshes with the second rack 125.

[0027] When using the lateral movement component 12, the third motor 123 is activated, driving the second gear 124 to rotate. The second gear 124 meshes with the second rack 125 fixed to the side of the bracket 31, converting the rotational motion into linear motion, thereby driving the bracket 31 to move smoothly and precisely laterally along the second slide rail 122. This structure, using the transmission form of the second gear 124 and the second rack 125, features high transmission rigidity, accurate positioning, and rapid response. It can effectively control the bracket 31 and the towing mechanism 3 mounted on the bracket 31 to move precisely forward and backward in the horizontal direction, achieving fine adjustment of the pallet 21's transfer position. The entire lateral movement process operates smoothly and with low noise, further improving the control accuracy and ease of operation of the device in automated pallet 21 handling.

[0028] The sliding mechanism 5 includes a first guide rail 51 and a first sliding block 52. The first guide rail 51 is fixedly installed on the top surface of the support frame 1 and is perpendicular to the second slide rail 122. The first sliding block 52 is slidably disposed on the first guide rail 51. Two placement plates 53 are provided on the first sliding block 52, which are used to support the tray 21 respectively.

[0029] When using the sliding mechanism 5, the first sliding block 52 moves laterally along the first guide rail 51 to precisely align the two placement plates 53 with the dragging mechanism 3 at the same horizontal level. Then, the electric telescopic rod 111 in the dragging mechanism 3 is activated to adjust the bracket 31 to a suitable height; next, the third motor 123 is activated to drive the second gear 124 to rotate, causing the bracket 31 to move forward along the second slide rail 122, smoothly transferring one end of the tray 21 onto the first placement plate 53. Next, the first motor 33 is activated to drive the first eccentric wheel 34 to rotate, causing the pin 35 to disengage from the current insertion hole 211; simultaneously, the third motor 123 continues to operate, pushing the tray 21 inward along the placement plate 53 a certain distance. Then, the first motor 33 operates again, causing the eccentric wheel's arc surface to lift the L-shaped slider 32, causing the pin 35 to insert into another insertion hole 211 on the tray 21. The third motor 123 continues to drive, further pushing the tray 21 inward. Repeat the cycle of "pin 35 retracts—pallet 21 advances—pin 35 inserts—advances again" until pallet 21 is fully supported on the two placement plates 53, completing the smooth transfer of pallet 21 from support 31 to placement plate 53. Through positioning by the first guide rail 51 and coordinated control of multiple motors, precise, segmented feeding of pallet 21 in the horizontal direction is achieved, effectively preventing pallet 21 from shifting or jamming during transfer. This significantly improves the stability and automation of the transfer process, enhancing the overall ease of operation and reliability of the equipment.

[0030] The clamping mechanism 6 includes a pneumatic clamp 61 and a displacement assembly 62. The displacement assembly 62 is mounted on the support frame 1. The displacement assembly 62 is equipped with a drive assembly 63 for driving the pneumatic clamp 61 to move up and down. The displacement assembly 62 is used to drive the pneumatic clamp 61 to move laterally. The pneumatic clamp 61 is mounted on the drive assembly 63 and is located above the two placement plates 53.

[0031] When using the clamping mechanism 6, the displacement component 62, in conjunction with the first guide rail 51 and the first slider, firstly transports the trays 21, which respectively carry the base and the outer shell on the two placement plates 53, to the working area directly below the pneumatic clamp 61. Then, the drive component 63 controls the pneumatic clamp 61 to descend, precisely clamping an outer shell and transferring it to the cold extrusion mold 4 for positioning. Next, again through the cooperation of the drive component 63 and the displacement system, the pneumatic clamp 61 moves above the base tray 21, clamps a base, and precisely places it in the cold extrusion mold 4 for alignment and sealing with the outer shell. The cold extrusion mold 4 starts, pressing the outer shell and base into a single structure. After completion, the pneumatic clamp 61 removes the formed workpiece and transfers it to the designated tray 21. The system cyclically executes the above material handling, transfer, pressing, and placement process until all bases and outer shells in the two trays 21 are assembled and formed. Through the coordinated control of multi-axis displacement and pneumatic clamping, high-precision and high-efficiency gripping and transfer of different workpieces are achieved, effectively replacing manual operation, significantly improving the automation level and production efficiency of assembly operations, while ensuring the consistency and reliability of molding quality.

[0032] The displacement component 62 includes a second guide rail 621 and a second slider 622. The second guide rail 621 is disposed on the support frame 1, and the second slider 622 is slidably disposed on the second guide rail 621. The drive component 63 is disposed on the side of the second slider 622 away from the second guide rail 621.

[0033] When in operation, the displacement component 62 achieves smooth and precise horizontal movement of the drive component 63 and the pneumatic gripper 61 through a precision guide rail pair formed by the second guide rail 621 and the second slider 622. The second slider 622 slides along the second guide rail 621, driving the entire drive unit and gripper to shift laterally, thereby quickly and accurately positioning the pneumatic gripper 61 to the working position above different pallets 21 or cold extrusion dies 4. This structure not only enhances the rigidity and repeatability of the transfer process but also significantly shortens the transfer time of the workpiece between different workstations, effectively improving the overall machine's operating rhythm and production efficiency.

[0034] The drive assembly 63 includes a fourth motor 631 and a second eccentric wheel 632. The fourth motor 631 is disposed on one side of the second slider 622. The second eccentric wheel 632 is fixedly installed on the output end of the fourth motor 631. A third slide rail 623 is disposed on the second slider 622. A fixed plate 624 is slidably connected to the third slide rail 623. A roller 625 is rotatably disposed on the side of the fixed plate 624 near the fourth motor 631. The arc surface of the roller 625 abuts against the arc surface of the second eccentric wheel 632. A pneumatic gripper 61 is fixedly installed on the fixed plate 624.

[0035] When using the drive assembly 63 to adjust the vertical displacement of the pneumatic gripper 61, the fourth motor 631 is activated, driving the second eccentric wheel 632 to rotate around its axis. As the long-diameter section of the second eccentric wheel 632 gradually turns towards the roller 625, its arc surface pushes the roller 625 upward, thereby causing the fixed plate 624, which is rotatably connected to the roller 625, to move smoothly upward along the third slide rail 623. The pneumatic gripper 61 on the fixed plate 624 rises accordingly, achieving a precise lifting action. Conversely, when the second eccentric wheel 632 continues to rotate until its short-diameter section contacts the roller 625, the pushing force on the roller 625 decreases or disappears. Under its own weight or external auxiliary reset action, the fixed plate 624 and the pneumatic gripper 61 slide smoothly downward along the third slide rail 623, thereby achieving the lowering movement of the gripper. The drive assembly 63 converts the rotational motion of the motor into the linear reciprocating motion of the gripper through the second eccentric wheel 632-roller 625 mechanism. It has a compact structure and rapid transmission response, and can accurately control the vertical lifting stroke of the pneumatic gripper 61. This effectively improves the flexibility and positioning accuracy of the equipment in grasping, placing and other operations, and further enhances the automation level and ease of operation of the overall system.

[0036] The cold extrusion die 4 includes a support arm 41, a support base 42, a sealing die 43, and a cylinder 44. The support arm 41 and the support base 42 are respectively disposed on the top surface of the support frame 1. The cylinder 44 is disposed on the support arm 41. The sealing die 43 is fixedly installed at the output end of the cylinder 44 and located on the top surface of the support base 42. When using the device, the outer shell is placed on the support base 42, and the base is placed on the outer shell. By activating the cylinder 44, the sealing die 43 is pushed, pressing the outer shell and the base together, thus improving the convenience of the device.

[0037] Working principle: During the operation of this device, the two sets of trays 21, arranged with the base and outer shell, are first sent into the oven 2 for vacuuming and heating. The oven temperature is 400℃, the vacuum is 1X10E-3Pa, and the working temperature of the trays is 200℃, completing the pre-processing and improving product performance. After the temperature inside the oven is reduced to the required range, the inner door of the oven 2 is opened. Subsequently, the system adjusts the height of the support base 112 with four electric telescopic rods to align it with the trays 21 inside the oven 2, and then sequentially starts the second motor 36 and the third motor 123, driving the sliding plate 115 and the bracket 31 to move towards the oven 2. At the same time, the two first motors 33 drive the eccentric wheel to rotate, pushing the L-shaped slider 32 upward, so that the pin 35 is inserted into the insertion hole 211 of the tray 21, thereby smoothly pulling the tray 21 out. Next, the first sliding block 52 moves laterally to align the two placement plates 53 with the tray 21. With the help of the coordinated action of the electric telescopic rod, the third motor 123 and the first motor 33, and the cyclic insertion and pushing of the pin 35, the two trays 21 are gradually transferred onto the placement plates 53. Finally, under the control of the displacement component 62 and the drive component 63, the pneumatic gripper 61 sequentially grabs the outer shell and the base, and transfers them to the cold extrusion mold 4 for positioning. After being pressed into shape by the pressing mold 43 driven by the cylinder 44, the molded part is placed back onto the tray 21. The system runs in a cycle until all bases and outer shells are assembled and pressed, realizing the automation of the entire process from material picking, transfer, alignment to molding, which significantly improves production efficiency and the consistency of molding quality.
