Description

Technical Field

[0001] This invention relates to the field of ultrasonic stamping, and more particularly to a multifunctional stamping machine that requires delayed cooling and reverse stamping. Specifically, it relates to a stamping machine that can flip products and has a redundant cooling station. Background Technology

[0002] A common type of injection molded product in the injection molding industry is... Figure 1 The most common ultrasonic stamping machine structure for this type of product is shown below. Figure 2 The robotic arm grips the material rod and ejects it from the mold; during stamping, the material rod moves upwards. This type of ultrasonic stamping machine only has a stamping function, making it single-function. Some products, due to material properties, are too hot immediately after exiting the mold, making stamping difficult; they need to be cooled for a period before stamping. Additionally, due to the product and mold structure, the gate is located at the bottom of the product. (See...) Figure 3 During forward stamping, residual gate material can easily scratch the product. Due to cooling, production efficiency is difficult to improve. Reverse stamping requires operators to manually place and stamp the product, posing a risk of workplace injury and also hindering efficiency. In the highly competitive plastics industry, production efficiency has a crucial impact on competitiveness.

[0003] Therefore, the applicant proposes this invention. Summary of the Invention

[0007] The aforementioned reverse-delay stamping machine incorporates a material receiving and flipping assembly, a multi-station cooling assembly, and a shifting stamping feed and discarding assembly in its structural design.

[0013] In the above preferred technical solution, the damping buffer I can protect the components of the stamping machine. When the flange plate of the high-speed rotating motor comes into contact with the damping buffer I, the damping buffer I can absorb and convert mechanical energy, reduce vibration and impact, reduce the wear and maintenance costs of mechanical equipment, and extend its service life.

[0014] A further preferred embodiment of the above-mentioned reverse delay stamping press has the following structure: The shifting stamping feeding and feeding assembly also includes a damping buffer II; The damping buffer II is installed on the lateral displacement plate via a limiting plate.

And, electronic control system 7; Among them, the flipping component base plate 4-1 of the receiving and flipping component 4 is installed on the workbench 1-1 of the support component 1 through the guide shaft I; the flat rotating shaft flange 5-6 of the multi-station cooling component 5 is installed on the flipping component base plate 4-1 of the synchronous belt pulley drive component 6-16 through the guide shaft II; and the shifting stamping feeding and discharging component base plate 6-12 of the shifting stamping feeding and discharging component 6 is installed on the workbench 1-1 of the support component 1 through the transverse shifting support leg plate 6-13. Among them, the electronic control system 7 controls the receiving and flipping component 4 to clamp the product I on the current injection molding robot 8, and after clamping the product I and flipping it 180°, it is placed into the flat rotating product seat 5-1, which is currently in the product feeding position of the multi-station cooling component 5. The electrical control system 7 controls the shifting stamping feeding and discarding component 6 to clamp product II, which is currently at the product discharge position of the multi-station cooling component 5, on the horizontal rotating product seat 5-1, and simultaneously clamp the material rod 100-3 of product III, which is currently at the stamping fixture 3. After clamping product II, it is moved laterally and placed into the stamping fixture 3, and after clamping product III, the material rod 100-3 is moved laterally and discarded.

[0021] The reverse delay stamping machine provided in this embodiment operates as follows: After startup, the injection molding robot 8 places product 100-1 onto the flipping gripper 4-10 and exits the flipping range. After receiving the signal that the injection molding robot 8 has completed feeding, the servo motor I 4-6 of the receiving and flipping assembly 4 rotates, flipping product 100-1 180°. After flipping, the material rod 100-3 is aligned with the flat rotating product seat 5-1 of the multi-station cooling assembly 5, which is currently in the product feeding position. The cylinder II 4-11 of the receiving and flipping assembly 4 drops, and the flipping gripper 4-10 inserts the material rod 100-3 of product 100-1 into the middle hole of the flat rotating product seat 5-1. The flipping gripper 4-10 releases, placing product 100-1 on the flat rotating product seat 5-1. The cylinder II 4-11 of the receiving and flipping component 4 lifts up, and the receiving and flipping component 4 leaves the product 100-1. The servo motor I 4-6 rotates in the opposite direction to restore the flipping gripper 4-10 to the receiving state, waiting for the next cycle.

[0022] After the flipping gripper 4-10 leaves the flat rotating product holder 5-1, the servo motor II 5-9 of the multi-station cooling component 5 rotates 90° (the number of flat rotating product holders 5-1 can be flexibly set according to the cooling requirements; the rotation angle will be different depending on the number. If it is set to 8 sets of flat rotating product holders 5-1, it will rotate 45°). In this way, it rotates once every time a material is placed.

[0023] When the rotating product holder 5-1 carrying product 100-1 rotates to the product discharge position, the cylinder Ⅲ 6-1 of the shifting stamping feed and discharge assembly 6 descends, and the stamping feed gripper 6-6 moves to the rotating product holder 5-1 currently in the product discharge position, clamping product 100-1. At the same time, the discharge gripper 6-7 clamps the product 100-1 material rod 100-3 (scrap) on the stamping fixture 3. As cylinder III 6-1 moves upward, the two grippers (stamping feed gripper 6-6 and discharge gripper 6-7) simultaneously clamp product 100-1 and scrap material and move upward. The material rod 100-3 of product 100-1 on the rotating product seat 5-1, which is currently in the product discharge position, is pulled out from the middle hole of the rotating product seat 5-1, while the material rod 100-3 on the stamping fixture 3 is pulled out from the middle hole of the stamping fixture 3. The servo motor III 6-18 of the shifting stamping feed and discharge assembly 6 rotates, and cylinder III 6-1 and the two grippers (stamping feed gripper 6-6 and discharge gripper 6-7) move along the track of the track slider assembly II 6-10. The stamping feed gripper 6-6 aligns the material rod 100-3 of product 100-1 with the middle hole of the stamping fixture 3, and the discharge gripper 6-7 sends the scrap material to the scrap chute. Cylinder III 6-1 moves downward, and the stamping feed gripper 6-6 inserts the product 100-1 material rod 100-3 into the middle hole of the stamping fixture 3. Both grippers (stamping feed gripper 6-6 and material discard gripper 6-7) simultaneously release, placing product 100-1 on the stamping fixture 3. Scrap material falls into the scrap bin along the scrap chute. Cylinder III 6-1 moves upward again to the top, and servo motor III 6-18 rotates in the opposite direction a short distance, clearing the space occupied by the punch from the two grippers (stamping feed gripper 6-6 and material discard gripper 6-7). The electrical control system 7 issues a stamping permission signal. The punch of the stamping machine 2 moves downward, emitting ultrasonic waves to vibrate product 100-1 off the stamping fixture 3. The punch then returns to the top, ready for the next stamping operation. After stamping is completed, the servo motor Ⅲ6-18 rotates again, moving the stamping feed gripper 6-6 above the flat rotating product seat 5-1, which is currently in the product discharge position. At the same time, the discharge gripper 6-7 moves to the top of the stamping fixture 3, aligning with the scrap material, and waits for the next cycle.

[0024] In this way, the reverse delay stamping press completes the actions of receiving material, flipping, cooling, stamping, and discarding waste material.

[0025] The aforementioned reverse-delay stamping machine incorporates a material receiving and flipping assembly 4, a multi-station cooling assembly 5, and a shifting stamping feed and discarding assembly 6 in its structural design. The material receiving and flipping assembly 4 receives the product 100-1 delivered by the injection molding robot 8, flips it, and places it in the multi-station cooling assembly 5. The multi-station cooling assembly 5 allows for simultaneous cooling of the product 100-1 at multiple stations, ensuring effective cooling while meeting production cycle requirements. The shifting stamping feed and discarding assembly 6 removes the cooled product 100-1 and places it into the stamping fixture 3; after stamping, it removes and discards the waste material.

[0026] This embodiment describes a reverse delay stamping machine, the structure of which includes: The receiving and flipping assembly 4 also includes a flipping origin sensing plate 4-13 and a miniature photoelectric sensor 4-14; The flip origin sensing plate 4-13 is installed on the flip rocker arm 4-8, and the miniature photoelectric sensor 4-14 is installed on the flip motor flange plate 4-5 and located on the flip trajectory of the flip origin sensing plate 4-13.

[0027] The aforementioned flip origin sensing plate 4-13 and micro photoelectric sensor 4-14 work together to accurately control and provide feedback on the flip displacement of the flip rocker arm 4-8, thereby improving the flip displacement accuracy of the receiving flip assembly 4.

[0028] This embodiment describes a reverse delay stamping machine, the structure of which includes: The receiving and flipping assembly 4 also includes a damping buffer I4-15; The damping buffer I4-15 is installed on the base plate 4-1 of the flipping assembly. The damping buffer I4-15 is located directly below the flipping motor flange plate 4-5 and on the translational trajectory of the flipping motor flange plate 4-5.

[0029] The aforementioned damping buffer I4-15 can protect the components of the press 2. When the high-speed rotating motor flange plate 4-5 contacts the damping buffer I4-15, the damping buffer I4-15 can absorb and convert mechanical energy, reduce vibration and impact, reduce the wear and maintenance costs of mechanical equipment, and extend its service life.

[0030] This embodiment describes a reverse delay stamping machine, the structure of which includes: The shifting stamping feeding and feeding assembly 6 also includes a damping buffer II 6-20; The damping buffer II 6-20 is installed on the lateral displacement plate 6-9 through the limiting plate. The damping buffer II 6-20 is located directly below the lateral displacement slide plate 6-2 and on the translation trajectory of the lateral displacement slide plate 6-2.

[0031] Similarly, the aforementioned damping buffer II 6-20 is also a component that can protect the press 2. When the high-speed lateral displacement slide plate 6-2 contacts the damping buffer II 6-20, the damping buffer II 6-20 can absorb and convert mechanical energy, reduce vibration and impact, reduce the wear and maintenance costs of mechanical equipment, and extend its service life.

[0032] As a second embodiment of the present invention, the reverse delay stamping machine provided in this embodiment has a generally consistent structure with the aforementioned first embodiment, such as... Figure 11 As shown, however, the receiving and flipping assembly 4 in this embodiment also includes a limiting stop 4-16; The limit stop bar 4-16 is installed on the flange plate 4-5 of the flip motor and is located on the flipping trajectory of the flipping rocker arm 4-8.

[0033] The aforementioned limit stop 4-16 can mechanically limit the tilting displacement of the tilting rocker arm 4-8, thereby effectively preventing the situation where "the tilting rocker arm 4-8, the cylinder I 4-9 installed on the tilting rocker arm 4-8, and the tilting gripper 4-10 collide with other parts of the press 2, resulting in damage to the parts".

[0034] This invention is not limited to the preferred embodiment described above. Anyone can derive other forms of product 100-1 under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
