Description

Technical Field

[0001] The present invention relates to the technical field of metal plate stamping, and particularly to a grooving die for metal fittings. Background Art

[0002] Stamping is a common metal forming processing method, which includes processes such as blanking, punching, bending, stretching, etc., and is widely used in various industrial fields. The principle of a sheet metal stamping die is to process a metal sheet into a component with the required shape by applying pressure, thereby obtaining a stamping product.

[0003] Referring to the Chinese invention patent with the publication number: CN 117259586 B and the name: Sheet Metal Stamping Die, this invention can act on the metal plate through the upper pressing plate and the lower support plate together; the punching tool and the punch can act on the metal plate simultaneously. When the punching tool and the punch act on the metal plate simultaneously, there is no need to reposition the metal plate, avoiding the problem of affecting the product quality due to excessive repositioning error.

[0004] However, in the actual use process, the above and similar technical solutions still have some problems: 1. In the stamping operation, the operation mechanism of the die involves the static fixation of the bottom die and the dynamic pressing of the top die. Due to the compact spatial configuration between the top die and the bottom die, when the bottom die cracks or is damaged due to long-term pressure or material fatigue, such defects are often difficult to be detected immediately, bringing potential quality risks to subsequent production; 2. When the operator places the sheet metal part to be stamped, a relatively dangerous action needs to be performed, that is, reaching into the narrow gap between the top die and the bottom die. If a mechanical failure (such as a control system failure) or an unexpected closing caused by an operation error occurs in this operation area, it will directly lead to a hand pinching accident. Although the bottom die is designed with an automatic ejection mechanism to eject the workpiece after stamping is completed, the final removal of the workpiece still depends on manual operation, which further increases the operation risk; 3. The bottom die maintains a constant upward posture, and its open design makes it easy for pollutants such as dust and debris in the external environment to invade the inside of the die groove. These pollutants may adhere to the die surface or be embedded in the sheet metal part during the stamping process, not only reducing the surface quality of the stamping part, but also possibly causing problems such as dimensional deviation and material damage, seriously affecting the stamping accuracy and overall quality of the final product.

A snap groove is provided on the side of the snap block facing the inside of the mold groove.

[0016] Compared with the prior art, the present invention provides a metal fitting groove pressing die, which has the following beneficial effects: 1. When stamping, the groove die moves downward, driving the horizontal bar and the rotating shaft to move downward. The gear moves downward and rotates at the same time, thereby controlling the rotation of the block so that the bottom die faces horizontally upward. The top die and the bottom die are closed to complete the stamping. When the stamping end is reset upward, the top plate is pulled to reset, thereby leading the bottom die to continue to flip outward and reset. The bottom die faces vertically outward, which is convenient for working again, thereby facilitating the placement of sheet metal parts, effectively avoiding damage to the opponent caused by mechanical failure during the stamping process, and making the operation safer. At the same time, the bottom die faces vertically outward with a wide field of vision, which is convenient for observing the bottom die and quickly judging whether the bottom die is damaged.

[0017] 2. When taking out the sheet metal part, the groove pressing die is pressed by pressing the pressure rod, which drives the rotating shaft to rotate, thereby driving the cam to rotate. The protruding end of the cam pushes the push cylinder, the fourth spring is compressed, and the push cylinder pushes the top cylinder to move outward. The third spring is compressed, and the top cylinder pushes out the stamped sheet metal part, and the sheet metal part and the buckle block are separated, thereby facilitating the removal of the sheet metal part and convenient operation.

[0018] 3. When the pressure rod is pressed, the protruding end of the cam pushes the pressure block. The compressed air inside the gas cylinder enters the push cylinder through the connecting pipe, the connecting hole and the cross pipe, and then enters the ejector cylinder through the pushing cylinder and is ejected from the end of the ejector cylinder. Therefore, when the sheet metal part is ejected, the compressed gas can help push the sheet metal part out. At the same time, the airflow formed can blow the surface of the bottom mold to remove dust on the surface of the bottom mold and prevent dust particles from affecting the quality of the sheet metal part.

Example 3:

[0032] Based on Example 2, Figure 8 、 Figure 9 、 Figure 11 、 Figure 12 、 Figure 13 and Figure 14, the metal fitting grooving mold, the control block 23 is connected to the jet mechanism 5, the jet mechanism 5 includes a pressure valve assembly 52, the lower mounting block 22 is connected to the pressure valve assembly 52, the pressure valve assembly 52 is connected to the cam 47, the pressure valve assembly 52 is connected to the connecting pipe 53 and the cross pipe 54, one end of the connecting pipe 53 is connected to the gas cylinder 55, and one end of the cross pipe 54 is installed on the pushing cylinder 44, so as to facilitate the gas to be drawn out, facilitate the separation of the sheet metal, and at the same time, the bottom mold 24 groove can be cleaned.

[0033] In the present invention, the pressure valve assembly 52 includes a bottom cylinder 522, the bottom cylinder 522 is installed on the lower mounting block 22, one end of the cross tube 54 and the connecting pipe 53 are both installed on the bottom cylinder 522, a pressure block 521 is slidably connected to the bottom cylinder 522, the side wall of the pressure block 521 is provided with a connecting hole 524, a sixth spring 523 is installed between the pressure block 521 and the bottom cylinder 522, the connecting pipe 53 is connected to the cross tube 54 through the connecting hole 524, one end of the pressure block 521 is in contact with the cam 47, and the pressure block 521 is pressed by the cam 47 to facilitate the control of the release of gas.

[0034] In the present invention, a compressed air component 51 is connected to the gas cylinder 55, and the compressed air component 51 includes a connecting pipe 515. A connecting pipe 515 is installed at one end of the gas cylinder 55, and a second one-way valve 516 is installed in the connecting pipe 515. A pressure chamber 513 is provided at one end of the control block 23 away from the lower mounting block 22. The control block 23 is slidably connected to a piston 511 through the pressure chamber 513. A fifth spring 514 is installed between the piston 511 and the control block 23. A first one-way valve 512 is installed on the piston 511. The pressure chamber 513 is connected to the outside through the first one-way valve 512. One end of the connecting pipe 515 extends into the interior of the pressure chamber 513. The pressure chamber 513 is connected to the gas cylinder 55 through the second one-way valve 516. Therefore, the gas cylinder 55 can be replenished with gas during each stamping process without manual gas replenishment, which is more convenient.

[0035] Working principle: During the process of grooving the fitting of the metal fitting, the fixing plate 1 is installed on the stamping table, and the top plate 21 is installed on the stamping end of the stamping machine. During the stamping process, the sheet metal part is inserted into the mold groove of the bottom mold 24. The sheet metal part pushes the buckle 61 to move outward, and the seventh spring 62 on the outside is compressed. One end of the sheet metal part extends into the inside of the buckle groove 63, and the buckle 61 limits the sheet metal part, thus preventing the sheet metal part from detaching. During stamping, the top plate 21 moves downward, driving the upper mounting block 25 and the top mold 27 to move downward. The elastic force of the second spring 264 is less than that of the first spring 261. Therefore, when the top plate 21 moves downward, the first spring 261 pushes the cross bar 263 downward, and the second spring 264 is compressed first. The cross bar 263 drives the rotating shaft 32 to move downward, driving the gear 36 to move downward. Under the action of the rack 34, the gear 36 moves downward and rotates at the same time, controlling the block 23 to rotate, making the bottom mold 24 horizontally face upward. At this time, the gear 36 and the rack 34 disengage, and the bottom end of the contact bar 35 will rotate to the horizontal and contact the contact bar 35, restricting the rotation of the gear 36 and the rotating shaft 32. The cross bar 263 drives the horizontal bottom mold 24 to move downward, and the bottom end of the control block 23 contacts the fixing plate 1, ensuring the stable force of the bottom mold 24. Continuing to push the top plate 21 downward, the telescopic rod 262 and the first spring 261 are compressed, and the upper mounting block 25 will approach the lower mounting block 22. The insertion post 281 extends into the insertion hole 282, and the insertion post 281 is inserted into the inside of the sleeve 283, ensuring the precise alignment of the top mold 27 and the bottom mold 24. When the bottom mold 24 is deviated, during the process of the insertion post 281 being inserted into the inside of the sleeve 283, it will push the bottom mold 24 to be calibrated, driving the lower mounting block 22 to move, and the rubber pad 284 will be compressed, ensuring the precise buckling of the top mold 27 and the bottom mold 24. When the top mold 27 and the bottom mold 24 contact, they push the buckle 61 into the inside of the bottom mold 24, and the buckle 61 disengages from the sheet metal part, avoiding damage to the buckle 61 during stamping. When the top mold 27 and the bottom mold 24 disengage, the buckle 61 will reset upward, and the edge of the sheet metal part will enter the buckle groove 63 again, restricting the detachment of the stamped sheet metal part. When the stamping end resets upward, the top plate 21 is pulled to reset, driving the bottom mold 24 to continue to turn outward and reset. The bottom mold 24 is vertically facing outward, facilitating rework and the placement of the sheet metal part, effectively avoiding damage to the hand caused by the top mold 27 due to mechanical failure during stamping, and the operation is safer; When removing the sheet metal part, press the pressure rod 41. The pressure rod 41 drives the rotating shaft 32 to rotate, driving the cam 47 to rotate. The protruding end of the cam 47 pushes the push cylinder 44, and the fourth spring 45 is compressed. The push cylinder 44 pushes the top cylinder 42 to move outward, and the third spring 43 is compressed. The top cylinder 42 pushes out the stamped sheet metal part, and the sheet metal part disengages from the buckle 61, facilitating the removal of the sheet metal part and the operation is convenient; When pressing the pressure lever 41, the protruding end of the cam 47 pushes the pressing block 521. The pressing block 521 moves towards the inside of the bottom cylinder 522, and the sixth spring 523 is compressed. The communication hole 524 will communicate with the horizontal pipe 54. The compressed air inside the gas cylinder 55 will enter the push cylinder 44 through the connecting pipe 53, the communication hole 524 and the horizontal pipe 54, and then enter the top cylinder 42 through the push cylinder 44 and spray out from the end of the top cylinder 42. Thus, when ejecting the sheet metal part, the compressed gas can play a role in assisting to push the sheet metal part away. At the same time, the formed air flow can blow the surface of the bottom die 24 to remove the dust on the surface of the bottom die 24 and avoid the dust particles from affecting the quality of the sheet metal part. During the stamping process, the bottom die 24 drives the control block 23 to slide downwards. The piston 511 at the bottom end of the control block 23 will abut against the surface of the fixed plate 1. The piston 511 is pressed into the pressure chamber 513, and the fifth spring 514 is compressed. The gas inside the pressure chamber 513 is unidirectionally pressed into the connecting pipe 515 through the second one-way valve 516, thereby replenishing the gas in the gas cylinder 55. When the piston 511 is separated from the fixed plate 1, the fifth spring 514 pushes the piston 511 to extend outwards, and the external gas enters the pressure chamber 513 through the first one-way valve 512, thus facilitating continuous air compression work.
