Description

Technical Field

[0001] The present invention relates to the technical field of guide pillars of a die set, and more particularly to a stamping die for a coffee machine shell. Background Art

[0002] When the coffee machine shell stamping die is in use, it mainly relies on the guide pillars to ensure the precise positioning of the various parts of the die during the processing process, preventing the die from displacement when closing or opening, thereby ensuring the dimensional accuracy and shape stability of the stamping parts, allowing the die group to perform precise stamping operations on the coffee machine shell.

[0003] After searching the existing public documents, the Chinese patent announcement number CN210080499U discloses a coffee machine shell stamping production mold. When in use, the mold assembly is installed with a hydraulic cylinder through the middle nesting of the left top of the mounting plate. The left top of the mounting plate is installed with a fixed top plate by screws, and a reinforcing rib is installed between the left lower part of the fixed top plate and the mounting plate by bolts. This utility model sets an "L"-shaped mounting plate, and opens a slide groove on it to connect the connector at the left end of the fixed plate, so that the pressure on the support rod can be reduced when the fixed plate is stamped, making the fixed plate more stable. However, this patent has the following defects.

[0004] When processing the coffee machine shell, the lower mold and the upper mold are needed for closed stamping, and at the same time, the stamping is carried out stably according to the specified vertical position through the guide pillar. The upper mold and the guide pillar are in contact through the ball inside the bearing. This can ensure that the upper mold and the lower mold maintain accurate stamping. However, if the processing and use time is long, the ball inside the bearing contacted by the guide pillar will wear and produce a larger gap. In this way, the mold group will produce offset shaking during stamping, and the stamped coffee machine shell will have a large size deviation. It is necessary to wait for maintenance personnel to arrive at the site to replace the ball inside the bearing contacted by the guide pillar. In this way, the equipment and personnel of the entire mold group need to wait for maintenance, which makes the mold group stop production for a long time for maintenance, and it is difficult to realize automatic maintenance in time, and it is difficult to quickly resume production and use. For this reason, a coffee machine shell stamping mold is needed. Summary of the invention

[0015] Technical effects and advantages of the present invention: 1. The present invention uses a guide recovery mechanism. When the main ball bearing has a wear problem and the multiple guide pillars cannot be used for precise guiding, the reduction motor is used to drive the bidirectional screw to rotate. The bidirectional screw drives the two socket blocks to move away from each other under the action of the thread transmission force, the socket block moves right, and the other socket block moves left. The linkage bar drives the pressure sensor to move right. The pressure sensor causes the push plate to move right, the push plate drives the two hinge blocks to move right, the hinge blocks drive the two pull shafts to move right, the guide sleeve block drives the arc sleeve to move backward, and the other arc sleeve behind the guide pillar moves forward. The multiple spare balls can be squeezed and contacted with the guide pillars according to the specified position and the specified pressure. In this way, the multiple guide pillars can quickly restore the guiding function, greatly shorten the waiting time, and greatly shorten the shutdown and maintenance time of the mold group. The mold group can be automatically repaired in time, and the mold group can quickly restore the production stamping operation of the coffee machine shell.

[0016] 2. The present invention adopts a guiding and positioning mechanism. When the push plate moves to the right, the push plate will drive the guide shaft to move to the right, and the mold support sleeve shaft block on the coffee shell will realize the guiding operation on the guide shaft. When the arc-shaped shaft sleeve moves backward, it will drive the sleeve slider to move backward, and the sleeve slider will drive the positioning distance sensor to move backward. The sleeve slider moves backward along the inner wall of the sliding frame, and the sensing block moves forward. The distance of the sensing block is sensed by the positioning distance sensor. The distance value sensed by the positioning distance sensor to the sensing block is zero. At the same time, the pressure value sensed by the pressure sensor is the same as the pressure value set by the controller. The reduction motor is turned off by the controller, which can ensure that multiple spare balls are in contact with the outer wall of the guide pillar according to the specified pressure and the specified position, thereby quickly and accurately restoring the guiding function of the multiple guide pillars, greatly shortening the shutdown and maintenance time of the mold group, and realizing automatic maintenance of the mold group in time.

[0017] 3. The present invention utilizes a guide offset detection component. When the coffee shell upper mold guides downward, the coffee shell upper mold will drive the sensing strip to move downward, and the reinforcement column provides support for the concave sleeve plate. The side distance sensor inside the concave sleeve plate senses the distance to the left side of the sensing strip, and the main distance sensor inside the concave sleeve plate senses the distance to the front of the sensing strip. When the distance value sensed by the side distance sensor is different from the distance set by the controller, it is known that the coffee shell upper mold has a guide offset problem, or when the distance value sensed by the main distance sensor is different from the distance set by the controller, it is known that the coffee shell upper mold has a guide offset problem. In this way, the stamping offset problem of the coffee shell upper mold can be known in time, and the guiding function of multiple guide pillars with problems can be quickly restored, so that the shutdown maintenance time of the mold group is greatly shortened, and the mold group can be automatically repaired in time.

[0018] The interaction of the above multiple functions firstly knows that the guide deviation problem occurs on the upper mold of the coffee shell, and multiple guide pillars are difficult to perform precise guiding operations. Secondly, multiple spare balls can be squeezed into contact with the guide pillars, and finally, multiple spare balls can be ensured to contact the outer wall of the guide pillars according to the specified pressure and the specified position. In summary, the guiding function of multiple guide pillars with problems is quickly restored, so that the shutdown and maintenance time of the mold group is greatly shortened, and the mold group can be automatically repaired in time, and the mold group quickly resumes the production and stamping operation of the coffee machine shell.

[0040] The working principle of the coffee machine housing stamping die of the present invention is as follows: Step 1: When the die set is punched, the coffee machine shell raw material plate is placed inside the positioning frame 25, and the coffee machine shell raw material plate is positioned by the positioning frame 25. At the same time, the coffee shell lower mold 1 supports multiple guide pillars 2, the guide pillars 2 support the support sleeve 22, and the support sleeve 22 supports the stamping electric cylinder 23. The controller 35 starts the stamping electric cylinder 23, the stamping electric cylinder 23 drives the concave block 21 to move downward, the concave block 21 drives the coffee shell upper mold 3 to move downward, and the coffee shell upper mold 3 drives multiple bearing sleeves 26 to move downward synchronously, and multiple main balls 27 inside the bearing sleeve 26 contact and roll with the outer wall of the guide pillar 2.

[0041] At the same time, the coffee shell upper mold 3 can be guided downward along the external main ball 27 of the guide pillar 2, and the coffee shell upper mold 3 drives the shell forming module 24 to press downward on the coffee machine shell raw material sheet, so that the coffee machine shell raw material sheet is stamped and formed in the groove body inside the coffee shell lower mold 1.

[0042] Step 2: During the guide deviation detection, when the coffee shell upper mold 3 is guided downward, the coffee shell upper mold 3 will drive the induction bar 41 to move downward, and at the same time, the coffee shell lower mold 1 supports the support block 36, the support block 36 supports the reinforcement column 37, the reinforcement column 37 provides support force for the concave sleeve plate 38, and the side distance sensor 39 inside the concave sleeve plate 38 performs distance sensing on the left side of the induction bar 41, and at the same time, the main distance sensor 40 inside the concave sleeve plate 38 performs distance sensing on the front of the induction bar 41. When the distance value sensed by the side distance sensor 39 is different from the distance set by the controller 35, it is known that the coffee shell upper mold 3 has a guide deviation problem, and it is known that the main ball 27 has a wear problem. Or when the distance value sensed by the main distance sensor 40 is different from the distance set by the controller 35, it is known that the coffee shell upper mold 3 has a guide deviation problem, and it is known that the main ball 27 has a wear problem.

[0043] Step 3: During the guide recovery, when there is a guide shaking problem between the coffee shell upper mold 3 and the coffee shell lower mold 1, the controller 35 immediately starts the reduction motor 6, the reduction motor 6 drives the bidirectional screw 5 to rotate, the bidirectional screw 5 rotates inside the support frame 4, and the bidirectional screw 5 drives the two sleeve blocks 7 to move away from each other under the action of the thread transmission force, so that the sleeve block 7 moves right, and the other sleeve block 7 moves left, the sleeve block 7 drives the linkage bar 8 to move right, the linkage bar 8 drives the pressure sensor 9 to move right, the pressure sensor 9 makes the push plate 10 move right, the push plate 10 drives the two hinge blocks 11 to move right, the hinge block 11 drives the two pull shafts 12 to move right, and the pull shaft 12 drives one end of the sleeve pull rod 13 to move right. At the same time, the sleeve pull rod 13 drives the connecting shaft 14 to move backward, and the connecting shaft 14 drives the concave block 15 to move backward.

[0044] At the same time, the concave block 15 drives the guide sleeve block 16 to move backward, the guide sleeve block 16 moves backward along the outer wall of the guide column 19, and the guide sleeve block 16 moves backward along the inner wall of the guide frame 20. At the same time, the guide sleeve block 16 drives the arc sleeve 17 to move backward, and another arc sleeve 17 behind the guide pillar 2 moves forward. The arc sleeve 17 drives multiple spare balls 18 to contact the outer wall of the guide pillar 2. Multiple spare balls 18 inside another arc sleeve 17 behind the guide pillar 2 move forward and are squeezed on the outer wall of the guide pillar 2. Multiple spare balls 18 can contact the guide pillar 2 according to the specified position and specified pressure to realize the function of quickly restoring the guide.

[0045] Step 4: During the guiding and positioning, when the push plate 10 moves to the right, the push plate 10 will drive the guide shaft 34 to move to the right, and the guide shaft 34 will slide to the right along the inner wall of the sleeve shaft block 33. At the same time, the coffee shell upper mold 3 supports the sleeve shaft block 33, and the sleeve shaft block 33 guides the guide shaft 34. At the same time, when the arc sleeve 17 moves backward, it will drive the sleeve slider 28 to move backward, and the sleeve slider 28 drives the positioning distance sensor 30 to move backward, so that the sleeve slider 28 moves backward along the outer wall of the support rod 29, and at the same time, the sleeve slider 28 moves backward along the inner wall of the sliding frame 32, and another arc sleeve 17 behind the guide pillar 2 will drive another sleeve slider 28 to move forward, so that the sensing block 31 moves forward, and the sensing block 31 is sensed by the positioning distance sensor 30. When the distance value sensed by the positioning distance sensor 30 to the sensing block 31 is zero, and the pressure value sensed by the pressure sensor 9 is the same as the pressure value set by the controller 35, the reduction motor 6 is turned off by the controller 35, so that multiple spare balls 18 can be accurately positioned on the outer wall of the guide pillar 2 according to the specified guide position, thereby restoring the normal guiding use of the guide pillar 2.

[0046] When the coffee shell upper mold 3 moves downward, the coffee shell upper mold 3 will drive multiple sliding frames 32 to move downward, the sliding frames 32 drive the support rod 29 to move downward, the support rod 29 drives two sleeve slide blocks 28 to move downward, the sleeve slide block 28 drives the arc sleeve 17 to move downward, the arc sleeve 17 drives the spare ball 18 to move downward, the spare ball 18 can realize the guided rolling along the outer wall of the guide pillar 2, ensuring that the coffee shell upper mold 3 can realize the stable vertical guiding operation along the outer wall of the guide pillar 2, even if the main ball 27 is damaged, the multiple spare balls 18 can be quickly fitted on the guide pillar 2, and the precise guiding function of the multiple guide pillars 2 can be quickly restored, so that the mold group can be quickly automatically repaired, and the normal use of the coffee shell upper mold 3 can be restored in an emergency. When production is not needed at night, maintenance personnel can repair the main ball 27.
