Description

Technical Field

[0001] The present invention relates to the field of production of heat-insulated cups, and more particularly to an automatic forming device for stainless steel heat-insulated cups with self-detection of die stamping depth. Background Art

[0002] Existing heat-insulated cups with a flat sealing structure have relatively high requirements for the length of the threaded section. When the length of the threaded section is appropriate, the threaded section and the cup lid fit perfectly, and at the same time, the bottom of the cup lid fits against the stepped end face position of the heat-insulated cup. When the length of the threaded section is insufficient, there is a gap between the sealing ring of the cup lid and the threaded section, resulting in insufficient sealing, so the heat-insulated cup will leak water. When the length of the threaded section is too long, there is a gap between the cup lid and the stepped end face of the cup body after the cup lid is closed, affecting the overall aesthetics of the cup.

[0003] The inner liner of the existing heat-insulated cup is manufactured by stamping. A pipe fitting is sleeved outside the die, and the upper stamping part carries the pipe fitting up and down the die. At the stage of pressing out the table, the degree of stamping is controlled by the machine itself. However, the existing machine itself does not have the measurement of the stamping stroke, but only performs periodic actions. Therefore, defective products often occur during the stamping process, resulting in waste of raw materials. Therefore, the present invention proposes an automatic forming device for stainless steel heat-insulated cups with self-detection of die stamping depth to solve the above problems. Summary of the Invention

[0004] In order to solve the problem that the existing stamping machine structure cannot measure the stamping distance of the cup, the present invention provides an automatic forming device for stainless steel heat-insulated cups with self-detection of die stamping depth.

[0005] The automatic forming device for stainless steel heat-insulated cups with self-detection of die stamping depth provided by the present invention adopts the following technical solutions:

[0006] An automatic forming device for stainless steel heat-insulated cups with self-detection of die stamping depth includes a machine body and a stamping mechanism on one side of the machine body. A track is provided on the machine body, and a number of workstations are evenly distributed on the track. The stamping mechanism includes a hydraulic cylinder, a lower die, and a stamping die. The stamping die is fixedly installed at the output end of the hydraulic cylinder and cooperates with the lower die to stamp and form a steel pipe. A ring-shaped metal sensor is provided at the stepped position of the lower die.

[0007] A fixed plate that slides vertically is provided on each of the workstations, and a telescopic mechanism is movably connected to the midline position of the fixed plate. The telescopic mechanism conveys the steel pipe to be processed along its axis.

[0008] A sliding frame structure is fixedly connected to the position of the machine body near the stamping mechanism, and the sliding frame structure includes two symmetrically arranged trapezoidal blocks on both sides and a cross bar in the middle that moves in the vertical direction, and the cross bar and the stamping die move downward synchronously;

[0009] The bottom of the fixed plate is rotatably connected with a roller, and the roller cooperates with the trapezoidal block to adjust the vertical height of the fixed plate. When the roller is raised, the telescopic mechanism is extended, and when the roller falls, the telescopic mechanism is reset.

[0010] Preferably, the machine body is fixedly mounted with four Corinthian columns at the position of the stamping mechanism, and a sliding platform is slidably connected to the Corinthian columns, and the sliding platform is fixedly connected to the stamping die through a locking structure.

[0011] Preferably, two sliding rods are vertically fixedly connected below the cross bar, and the sliding rods are slidably connected to the connecting piece between the two trapezoidal blocks, and an extrusion spring is sleeved on the outer side of the sliding rod to elastically connect the connecting piece between the cross bar and the trapezoidal blocks.

[0012] Preferably, the telescopic mechanism includes a sleeve, an electromagnet, a threaded ring and a bidirectional threaded rod, the sleeve is fixedly connected to the midline position of the fixed plate, the bidirectional threaded rod is slidably mounted on the inner side of the sleeve, and the threaded ring is threadedly connected to the outer side of the bidirectional threaded rod, the threaded ring drives the bidirectional threaded rod to perform axial displacement, and the electromagnet is fixedly connected to the end of the bidirectional threaded rod.

[0013] Preferably, a synchronous belt is arranged between the roller and the threaded ring, and the synchronous belt drives the roller and the threaded ring to rotate synchronously. When the roller is in place, the threaded ring drives the steel pipe to the top of the lower mold through the threaded bidirectional threaded rod, and the roller continues to rotate, and the bidirectional threaded rod is recovered and reset.

[0014] Preferably, the bidirectional threaded rod is a multi-threaded rod, and the inner side of the threaded ring is provided with a plurality of convex threads matching the bidirectional threaded rod.

[0015] Preferably, each of the workstations is fixedly connected with a stand, and the fixed plate is slidably mounted on the stand.

[0016] In summary, the present invention includes at least one of the following beneficial technical effects:

[0017] By precisely processing the lower die during its production process and setting a metal sensor at its step position, the mechanical stamping distance can be controlled by the metal sensor when the steel pipe is stamped, thereby ensuring that the stamping is in place, reducing defective products, improving processing effects, and reducing costs;

[0018] By setting a fixed plate that can slide vertically at the work station, and rotatably connecting rollers below the fixed plate, and fixedly connecting a sliding frame structure to one side of the machine body, through the mutual cooperation between the rollers and the sliding frame structure, while lifting the vertical height of the steel pipe, under the drive of the bidirectional threaded rod, the steel pipe undergoes axial displacement, so as to ensure that the steel pipe is conveyed directly above the lower die. The sliding frame structure cooperates with the telescopic movement of the hydraulic cylinder to realize the convenient picking and placing of the steel pipe on the lower die, thereby realizing automated processing and improving the processing efficiency of the inner liner of the thermos cup;

[0019] Since the track has a certain length and has multiple work stations, other processing structures can be set around the track, so as to synchronously perform operations such as cutting and grinding on the steel pipe, thereby further improving the processing efficiency of the inner liner of the thermos cup.

Detailed implementation mode

[0028] The following will further describe the present invention in detail in conjunction with the attached Figures 1-7 drawings.

[0029] Embodiment 1:

[0030] Referring to Figures 1-7 , an automatic forming device for a stainless steel thermos cup with self-detection of the stamping depth of a die, comprising a body 1 and a stamping mechanism on one side of the body 1. A track 4 is arranged on the body 1, and a plurality of working stations 5 are evenly distributed on the track 4. The stamping mechanism includes a hydraulic cylinder 2, a lower die 3 and a stamping die 14. The stamping die 14 is fixedly installed at the output end of the hydraulic cylinder 2 and cooperates with the lower die 3 to stamp and form a steel pipe. Four tie bars 12 are fixedly installed at the position of the body 1 where the stamping mechanism is located, and a sliding table 13 is slidably connected to the tie bars 12. The sliding table 13 is fixedly connected to the stamping die 14 through a locking structure 15. The tie bars 12 guide the sliding table 13 to ensure the displacement stability of the sliding table 13. The locking structure 15 is in a C-shaped structure, and the front view of the stamping die 14 is in an "I" shape structure. A bolt is threadedly connected to the upper end of the locking structure 15, and the contact between the bolt and the sliding table 13 is used to ensure the fixation between the stamping die 14 and the locking structure 15;

[0031] A ring-shaped metal sensor 301 is arranged at the step position of the lower die 3. The distance between the ring-shaped metal sensor 301 and the upper end surface of the lower die 3 is accurately controlled during the manufacturing process. When the steel pipe moves downward along with the stamping die 14 towards the lower die 3, its threaded section adheres to the outer side of the top end of the lower die 3. When the lower die 3 and the stamping die 14 reach the position, the step position of the thermos cup is pressed out. When the inner wall of the steel pipe is in contact with the metal sensor 301, the metal sensor 301 is triggered, indicating that the stamping is in place, and the information is fed back to the outside. At this time, the stamping mechanism retracts, the device continues to operate, and the next working station 5 is ready to enter the stamping position;

[0032] On each station 5, a fixed plate 6 that slides vertically is provided, and a telescopic mechanism 9 is movably connected to the midline position of the fixed plate 6. The telescopic mechanism 9 conveys the position of the steel pipe to be processed along its axis. The telescopic mechanism 9 includes a sleeve 901, an electromagnet 902, a threaded ring 903, and a bidirectional threaded rod 905. The sleeve 901 is fixedly connected to the midline position of the fixed plate 6. The bidirectional threaded rod 905 is sleeved inside the sleeve 901, and the threaded ring 903 is threadedly connected to the outside of the bidirectional threaded rod 905. The threaded ring 903 drives the bidirectional threaded rod 905 to perform axial displacement. The electromagnet 902 is fixedly connected to the end of the bidirectional threaded rod 905. The electromagnet 902 adopts a detachable arc structure to ensure the adsorption effect on the steel pipe, thereby ensuring the stable position of the steel pipe during the processing. A plurality of different processing positions are provided on the outside of the track 4, so that the steel pipe can perform multiple operations during one revolution, improving the processing efficiency. On each station 5, a vertical frame 7 is fixedly connected. The fixed plate 6 is sleeved on the vertical frame 7. The vertical frame 7 cooperates with the trapezoidal block 801, so that when the roller 11 displaces on the trapezoidal block 801, the fixed plate 6 performs vertical displacement along the vertical frame 7 to lift the bottom position of the steel pipe, so that it can cooperate with the lower die 3;

[0033] A sliding frame structure 8 is fixedly connected to the position of the machine body 1 close to the stamping mechanism. The sliding frame structure 8 includes two symmetrically arranged trapezoidal blocks 801 on both sides and a cross bar 802 that displaces vertically in the middle. The cross bar 802 and the stamping die 14 move downward synchronously. Two sliding rods 803 are vertically fixedly connected below the cross bar 802, and the sliding rods 803 are slidably connected to the connecting piece between the two trapezoidal blocks 801. And a compression spring 804 is sleeved on the outside of the sliding rod 803, so that the connecting piece between the cross bar 802 and the trapezoidal block 801 is elastically connected. The roller 11 moves to the middle position of the cross bar 802 under the drive of the track 4. At this time, the hydraulic cylinder 2 extends, driving the stamping die 14 to move downward. When the stamping die 14 contacts the steel pipe, since there is no support below, the steel pipe moves downward together with the stamping die 14 and slides onto the lower die 3 for stamping operation. After the stamping is completed, the hydraulic cylinder 2 resets. At this time, under the action of the compression spring 804, the cross bar 802 resets. At this time, the highest positions of the cross bar 802 and the trapezoidal block 801 are reconnected. The servo motor 10 rotates, and the chain on the track 4 rotates, driving the station 5 to displace. The roller 11 returns to the initial height through the inclined surface of another trapezoidal block 801;

[0034] The bottom of the fixed plate 6 is rotatably connected with a roller 11. The roller 11 cooperates with the trapezoidal block 801 to adjust the vertical height of the fixed plate 6. When the roller 11 rises, the telescopic mechanism 9 extends. When the roller 11 falls, the telescopic mechanism 9 resets. When the working station 5 is displaced under the drive of the track 4, when the roller 11 moves to the position of the trapezoidal block 801, the roller 11 climbs along the inclined surface of the trapezoidal block 801. At this time, the fixed plate 6 slides above the vertical frame 7, thereby lifting the position of the bottom of the steel pipe so that it can be higher than the top of the lower die 3, thus ensuring the subsequent stamping. A synchronous belt 904 is arranged between the roller 11 and the threaded ring 903. The synchronous belt 904 drives the roller 11 and the threaded ring 903 to rotate synchronously. When the roller 11 is in place, the threaded ring 903 drives the steel pipe to directly above the lower die 3 through the bidirectional threaded rod 905 connected by threads. When the roller 11 continues to rotate, the bidirectional threaded rod 905 retracts and resets. When the roller 11 contacts and rotates with the trapezoidal block 801, the threaded ring 903 is driven to rotate through the synchronous belt 904. When the threaded ring 903 rotates, the bidirectional threaded rod 905 connected by threads makes an axial displacement. When the roller 11 is in place, the threaded ring 903 and the bidirectional threaded rod 905 also reach the commutation position, so as to ensure that when the roller 11 moves again, the bidirectional threaded rod 905 retracts and resets, so as to prevent the steel pipe from touching the tie rod 12 during displacement. The bidirectional threaded rod 905 is a multi-threaded thread. Several convex threads matching the bidirectional threaded rod 905 are arranged on the inner side of the threaded ring 903. The double thread helps to improve the stability of the transmission. At the same time, under the condition of rotating the same number of turns, a longer transmission distance can be obtained, so as to ensure that when the threaded ring 903 and the bidirectional threaded rod 905 cooperate, the transmission distance of the steel pipe is long enough to ensure that the transmission is in place.
