Description

Technical Field

[0001] The invention relates to the technical field of stamping dies, in particular to a stamping die for sheet metal parts processed by packaging equipment. Background Art

[0002] A stamping die is a special process equipment used to process materials into parts during cold stamping. The working principle is to use a die installed on a press to apply pressure to the material, causing the material to undergo plastic deformation and separation in a cavity of a specific shape and size of the die, thereby obtaining parts of the desired shape and size. The press provides power to drive the upper and lower dies of the die to move relative to each other. The upper die is usually installed on the slide of the press, and the lower die is fixed on the workbench of the press. When the slide of the press moves downward, the upper die moves downward with it and closes with the lower die to stamp the material placed in the cavity of the die. When the slide moves upward, the upper die rises with it, the die opens, and the stamped parts or blanks are taken out to complete a stamping cycle. A sheet metal stamping die is a process equipment used to stamp sheet metal materials to obtain parts of specific shapes and sizes.

[0003] During the stamping and bending process, in order to ensure the accurate direction of the stamping process, the guide parts are usually cleaned during the stamping process to remove impurities adhering to the surface of the guide parts. When removing impurities, a tool is usually used for scraping. However, during the scraping process, the pressure cannot be buffered or when encountering larger impurities, it will cause greater wear on the guide parts and affect the accuracy of the guide. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A sheet metal stamping die for packaging equipment processing, comprising:

[0006] A top mold, the bottom of which is provided with guide pillars, which are symmetrically installed along the center position of the axis of the top mold;

[0007] A bottom mold, a guide cylinder is installed on the top of the bottom mold, the guide cylinder corresponds to the guide post one by one, and the guide post is slidably installed inside the guide cylinder;

[0008] A ball groove ring is fixedly installed on the top of the inner wall of the guide cylinder, and air holes are evenly opened on the bottom of the outer side of the guide cylinder. Balls are rotatably installed on the inner wall of the ball groove ring. The contact between the ball and the outer side of the guide column is utilized to reduce the contact surface between the ball and the guide column during the sliding process of the guide column. At the same time, the sliding friction force is converted into rolling friction force, and the friction force between the surface of the guide column is reduced, so as to ensure the smoothness of the guide column when sliding, reduce the wear of the guide column, and avoid excessive wear of the guide column, which affects the direction accuracy when the top mold and the bottom mold are stamped. The balls are evenly installed along the center of the ball groove ring, and the opposite side of the ball is slidably adapted to the outer side of the guide column;

[0009] A ring cover is fixedly installed on the top of the guide cylinder, and a gear cylinder is installed on the inner wall of the ring cover. Spiral blocks are evenly arranged on the top of the outer side of the gear cylinder, and spiral grooves are evenly opened on the inner wall of the ring cover. Through the spiral grooves of the ring cover and the spiral blocks on the outer side of the gear cylinder, impurities on the guide column contact the gear cylinder, and the rubber pad is annularly deformed by the contact pressure to make the gear cylinder move downward to buffer the pressure. At the same time, it rotates during the downward movement to clean the contacted impurities, thereby improving the cleaning effect and avoiding excessive accumulation of impurities that affect the smoothness of stamping. The ring cover is slidably adapted to the spiral blocks of the gear cylinder through the spiral grooves, and tooth grooves are evenly opened on the top of the gear cylinder, and a rubber gasket is fixedly installed on the bottom of the gear cylinder, and the bottom of the rubber gasket is fixedly connected to the bottom of the inner wall of the ring cover.

[0010] Preferably, the bottom mold includes a bottom plate, the guide cylinder is symmetrically installed at the corners of the top of the bottom plate, a connecting plate is fixedly installed at the center position of the top of the bottom plate, a bottom profile frame is fixedly installed on the top of the connecting plate, rollers are rotatably installed on the tops of both sides of the inner wall of the bottom profile frame, a column cylinder is fixedly installed on the bottom of the inner wall of the bottom profile frame, the column cylinder is symmetrically installed along the center position of the axis of the bottom profile frame, and sliding columns are slidably installed on the inner walls of the column cylinders, a pad is fixedly installed on the top of the sliding column, a first spring is fixedly installed between the pad and the bottom of the inner wall of the bottom profile frame, side plates are fixedly installed on the tops of both sides of the bottom profile frame, and the side Connecting rods are fixedly installed on both sides of the outer side of the plate, and beam plates are slidably installed on the outer side of the connecting rods. Studs are rotatably installed on the inner wall of the side plate. The studs are threadedly connected to the beam plates. The positions of the beam plates on both sides are adjusted before stamping so that the stamping position of the plate corresponds to the bottom frame, avoiding incorrect stamping position and allowing workers to put in the plate faster. At the same time, during the bending process, the friction between the bending position of the plate and the bottom mold can be reduced by rotating the roller, ensuring that the bending position of the plate is smoothly bent during stamping and bending, thereby improving the bending effect. The end of the stud away from the side plate passes through the beam plate, and the inner wall of the beam plate is threadedly connected to the outer side of the stud.

[0011] Preferably, a side pad is fixedly installed on the top of the beam plate, the top of the side pad is flush with the top of the pad, and frame plates are fixedly installed on both sides of the top of the side pad, and side pads are slidably installed between the frame plates, and elastic pads are fixedly installed between the side pads and the frame plates, and the elastic pads are made of rubber material, and the top of the side pads close to the pad is an inclined surface. The position of the plate is positioned through the contact between the side pads and the two sides of the plate, and the top mold is cooperated to ensure the position accuracy during bending, and the inclined surface of the top of the opposite surface of the side pads enables workers to press the plate from top to bottom between the side pads, thereby improving the efficiency of workers when placing plates. At the same time, the elastic pads on the non-opposite surfaces of the side pads make the plate encounter the obstruction of the side pads on both sides when bending. At this time, the contact pressure is transmitted to the elastic pads through the side pads, causing the elastic pads to deform, providing space for the side pads to move to both sides, ensuring the normal stamping and bending of the plate, and the bottom of the side pads is tightly fitted with the top of the side pads.

[0012] Preferably, the top mold includes a top plate, a fixed beam is fixedly installed at the center of the bottom of the top plate, a slot plate is fixedly installed at the bottom of the fixed beam, plate slots are opened on both sides of the bottom of the slot plate, and slide slots are symmetrically opened on both sides of the slot plate, an inner pressure plate is fixedly installed at the center of the bottom of the slot plate, and side pressure plates are installed on both sides of the slot plate, and the opposite surfaces of the side pressure plates are provided with clamping strips, and the side pressure plates are slidably adapted to the slide slots of the slot plates through the clamping strips, and the side pressure plates cooperate with the second spring during the process of stamping and bending the plate. During the process, in order to buffer the pressure at the bending place, the bending process is carried out slowly with the stroke of the stamping, so as to avoid direct bending at the moment of contact, which may cause the plate to break at the bending position. Fixed columns are fixedly installed on both sides of the top of the slot plate, and the outer sides of the fixed columns are slidably matched with the inner walls of the side pressure plates. A second spring is fixedly installed between the side pressure plate and the slot plate, and the bottom of the inner pressure plate is symmetrically provided with oblique protrusions, and the side pressure plate is matched with the plate slot of the slot plate, and when the side pressure plate is in the plate slot position, the bottom of the side pressure plate is flush with the bottom of the inner pressure plate.

[0013] The present invention provides a sheet metal stamping die for processing packaging equipment. It has the following beneficial effects:

[0014] 1. The sheet metal stamping die processed by the packaging equipment cooperates with the spiral block on the outside of the gear cylinder through the spiral groove of the ring cover, so that the impurities on the guide column contact the gear cylinder, and then use the contact pressure to compress the rubber pad to change annularly, so that the gear cylinder moves downward to buffer the pressure. At the same time, it rotates during the downward movement to clean the impurities in contact, improve the cleaning effect, and avoid excessive accumulation of impurities that affect the smoothness of stamping.

[0015] 2. The sheet metal stamping die processed by the packaging equipment reduces the contact surface with the guide post during the sliding of the guide post through the contact between the ball and the outside of the guide post. At the same time, the sliding friction force is converted into rolling friction force, reducing the friction between the surface of the guide post, ensuring the smooth sliding of the guide post, reducing the wear of the guide post, and avoiding excessive wear of the guide post, which affects the directional accuracy of the top die and the bottom die when stamping the sheet metal.

[0016] 3. The sheet metal stamping die processed by the packaging equipment is connected to the beam plate through the threaded connection of the studs. The position of the beam plates on both sides is adjusted before stamping, so that the stamping position of the sheet metal corresponds to the bottom frame, avoiding the error of the stamping position and allowing workers to put the sheet metal in faster. At the same time, during the bending process, the friction between the bending position of the sheet metal and the bottom die can be reduced by the rotation of the roller, ensuring that the bending position of the sheet metal is smoothly bent during stamping and bending, thereby improving the bending effect.

[0017] 4. The sheet metal stamping die processed by the packaging equipment locates the position of the sheet through the contact between the side pads and the two sides of the sheet, and cooperates with the top die to ensure the position accuracy during bending. The inclined surface on the top of the opposite side of the side pad allows workers to press the sheet from top to bottom between the side pads, which improves the efficiency of workers when placing the sheet. At the same time, the elastic pads on the non-opposite sides of the side pads make the sheet encounter the obstruction of the side pads on both sides when it is bent. At this time, the contact pressure is transmitted to the elastic pads through the side pads, causing the elastic pads to deform, providing space for the side pads to move to both sides, and ensuring the normal stamping and bending of the sheet.

[0018] 5. The sheet metal stamping die processed by the packaging equipment, through the cooperation of the side pressure plate and the second spring, buffers the pressure at the bending point during the stamping and bending of the sheet, so that the bending process proceeds slowly along with the stamping stroke, avoiding direct bending at the moment of contact, which would cause the sheet to break at the bending position.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The first embodiment, as Figures 1 to 4 As shown, the present invention provides a technical solution:

[0031] A sheet metal stamping die for packaging equipment processing, comprising:

[0032] A top mold 1, a guide post 4 is installed at the bottom of the top mold 1, and the guide post 4 is symmetrically installed along the center position of the axis of the top mold 1;

Balls 6 are rotatably installed on the inner wall of the bead groove ring 7. When the guide column 4 slides inside the guide cylinder 3, the ball 6 rotatably installed on the inner wall of the bead groove ring 7 contacts the outer side of the guide column 4 through the bead groove ring 7 installed inside the guide cylinder 3, thereby reducing the contact surface with the guide column 4. At the same time, the friction between the ball 6 and the guide column 4 is reduced by cooperating with the rolling of the ball 6, thereby ensuring the smoothness of the guide column 4 when sliding. The ball 6 is evenly installed along the center position of the bead groove ring 7, and the opposite side of the ball 6 is slidably adapted to the outer side of the guide column 4.

During the sliding process of the guide column 4, the surface of the guide column 4 is cleaned, and impurities adhering to the surface of the guide column 4 are cleaned. During the cleaning process, when the impurities contact the gear cylinder 5, the downwardly moving guide column 4 presses the gear cylinder 5 through the impurities, so that the gear cylinder 5 presses the rubber gasket 9 downward to deform, so that the gear cylinder 5 slides in the spiral groove of the ring cover 8 through the spiral blocks, and the gear cylinder 5 rotates while moving downward. The top of the gear cylinder 5 is evenly provided with tooth grooves, and the bottom of the gear cylinder 5 is fixedly installed with a rubber gasket 9, and the bottom of the rubber gasket 9 is fixedly connected to the bottom of the inner wall of the ring cover 8.

[0036] The second embodiment is based on the first embodiment. Figure 5 to Figure 6As shown, the bottom mold 2 includes a bottom plate 201, and the guide cylinder 3 is symmetrically installed at the corners of the top of the bottom plate 201. A connecting plate 206 is fixedly installed at the center position of the top of the bottom plate 201, and a bottom frame 208 is fixedly installed on the top of the connecting plate 206. Rollers 204 are rotatably installed on the tops of both sides of the inner wall of the bottom frame 208. A column cylinder 207 is fixedly installed at the bottom of the inner wall of the bottom frame 208. The column cylinder 207 is symmetrically installed along the center position of the axis of the bottom frame 208, and a sliding column 203 is slidably installed on the inner wall of the column cylinder 207. A pad 205 is fixedly installed on the top of the sliding column 203, and a first spring 202 is fixedly installed between the pad 205 and the bottom of the inner wall of the bottom frame 208. The worker presses the required The bent sheet metal is placed on the top of the pad 205. Before placing it in, the worker can use a wrench to turn the stud 210 to rotate the stud 210, and use the threaded connection between the stud 210 and the beam 211 to make the beam 211 slide on the outside of the connecting rod 216 to adjust the position of the beam 211. The tops of both sides of the bottom frame 208 are fixedly installed with side panels 209, and the two sides of the outer side of the side panels 209 are fixedly installed with connecting rods 216. The outer side of the connecting rod 216 is slidably installed with the beam 211. The inner wall of the side panel 209 is rotatably installed with the stud 210, and the end of the stud 210 away from the side panel 209 passes through the beam 211, and the inner wall of the beam 211 is threadedly connected to the outer side of the stud 210.

[0037] A side pad 215 is fixedly installed on the top of the beam plate 211, and the top of the side pad 215 is flush with the top of the pad 205, and frame plates 212 are fixedly installed on both sides of the top of the side pad 215. Side pads 213 are slidably installed between the frame plates 212, and elastic pads 214 are fixedly installed between the side pads 213 and the frame plates 212. The elastic pads 214 are made of rubber material. During the adjustment process, the side pads 215 are driven to move by the beam plate 211, so that the opposite surface of the side pads 213 contacts the side edge of the plate, the position of the plate is positioned, and the bending of the plate is controlled. Position, and during the bending process, the roller 204 cooperates with the top mold 1 to reduce friction at the bending position of the plate to ensure smooth bending of the plate. During stamping, the pressure is transmitted to the pad 205 through the plate, so that the pad 205 compresses the first spring 202, and the sliding adaptation of the sliding column 203 and the column tube 207 is utilized to make the pad 205 move vertically downward, so that the bottom frame 208 cooperates with the top mold 1 to complete the stamping and bending. The top of the side pad 213 close to the pad 205 side is an inclined surface, and the bottom of the side pad 213 fits tightly with the top of the side pad 215.

[0038] The third embodiment is based on the first and second embodiments. Figures 7 to 9As shown, the top mold 1 includes a top plate 11, a fixed beam 13 is fixedly installed at the center position of the bottom of the top plate 11, a slot plate 14 is fixedly installed at the bottom of the fixed beam 13, plate slots are opened on both sides of the bottom of the slot plate 14, and sliding grooves are symmetrically opened on both sides of the slot plate 14. When impacting the plate placed on the top of the bottom mold 2, the side pressure plate 12 first contacts the bending position of the plate, and cooperates with the bottom frame 208 to bend during the continuous downward movement of the top mold 1, an inner pressure plate 17 is fixedly installed at the center position of the bottom of the slot plate 14, and side pressure plates 12 are installed on both sides of the slot plate 14, and the opposite surfaces of the side pressure plates 12 are provided with clamping strips, and the side pressure plates 12 are slidably adapted to the sliding grooves of the slot plate 14 through the clamping strips.

[0039] Fixed columns 15 are fixedly installed on both sides of the top of the groove plate 14, and the outer sides of the fixed columns 15 are slidably adapted to the inner walls of the side pressure plates 12. A second spring 16 is fixedly installed between the side pressure plates 12 and the groove plate 14, and oblique protrusions are symmetrically arranged at the bottom of the inner pressure plate 17. After the side pressure plates 12 contact the plate, the contact pressure between the side pressure plates 12 and the plate is transmitted to the second spring 16, so that the side pressure plates 12 slide upward a certain distance under the restriction of the fixed columns 15 until the side pressure plates 12 are stuck in the plate groove of the groove plate 14. At this time, the bottom of the inner pressure plate 17 is flush with the bottom of the side pressure plates 12, and the stamping and bending process is completed in the process of continuing to move downward. The side pressure plates 12 are adapted to the plate grooves of the groove plates 14, and when the side pressure plates 12 are in the plate groove position, the bottom of the side pressure plates 12 is flush with the bottom of the inner pressure plates 17.

[0040] When in use, the mold is installed in the stamping equipment, and the top mold 1 is connected to the cylinder of the stamping equipment. During stamping, the sheet metal is placed on the top of the bottom mold 2, so that the bottom mold 2 supports the sheet metal and positions the sheet metal. During stamping, the top mold 1 is driven by the cylinder of the stamping equipment to impact the bottom mold 2. The bottom mold 2 cooperates with the top mold 1 to stamp and bend the sheet metal. At the same time, in the process of the top mold 1 and the bottom mold 2 approaching each other, the guide column 4 slides inside the guide cylinder 3.

[0041] When the guide post 4 slides inside the guide cylinder 3, the ball 6 rotatably installed on the inner wall of the ball groove ring 7 through the bead groove ring 7 installed inside the guide cylinder 3 contacts the outer side of the guide post 4, thereby reducing the contact surface with the guide post 4. At the same time, the friction between the ball 6 and the guide post 4 is reduced in conjunction with the rolling of the ball 6, thereby ensuring the smooth sliding of the guide post 4. At the same time, during the sliding process of the guide post 4, the tooth groove position of the gear cylinder 5 contacts the outer side of the guide post 4. During the sliding process of the guide post 4, the surface of the guide post 4 is cleaned, and impurities adhered to the surface of the guide post 4 are cleaned. During the cleaning process, when impurities contact the gear cylinder 5, the guide post 4 moving downward presses the gear cylinder 5 through the impurities, causing the gear cylinder 5 to press the rubber gasket 9 downward to deform, so that the gear cylinder 5 slides in the spiral groove of the ring cover 8 through the spiral block, and the gear cylinder 5 rotates while moving downward.

[0042] In the bottom die 2, the worker puts the sheet metal part to be stamped and bent on the top of the pad 205. Before putting it in, the worker can use a wrench to rotate the stud 210 to rotate the stud 210, and use the threaded connection between the stud 210 and the beam plate 211 to slide the beam plate 211 on the outside of the connecting rod 216 to adjust the position of the beam plate 211. During the adjustment process, the side pad 215 is driven to move by the beam plate 211, so that the opposite surface of the side pad 213 is in contact with the side edge of the plate. The plate is positioned and the bending position of the plate is controlled. At the same time, during the bending process, the roller 204 cooperates with the top die 1 to reduce friction at the bending position of the plate to ensure smooth bending of the plate. During stamping, the pressure is transmitted to the pad 205 through the plate, so that the pad 205 compresses the first spring 202. The sliding adaptation of the sliding column 203 and the column tube 207 is utilized to make the pad 205 move vertically downward, so that the bottom frame 208 cooperates with the top die 1 to complete the stamping and bending.

[0043] In the top die 1, when impacting the plate placed on the top of the bottom die 2, the side pressure plate 12 first contacts the bending position of the plate, and cooperates with the bottom frame 208 to bend while the top die 1 continues to move downward. At the same time, after the side pressure plate 12 contacts the plate, the contact pressure between the side pressure plate 12 and the plate is transmitted to the second spring 16, so that the side pressure plate 12 slides upward a certain distance under the restriction of the fixed column 15 until the side pressure plate 12 is stuck in the plate groove of the groove plate 14. At this time, the bottom of the inner pressure plate 17 is flush with the bottom of the side pressure plate 12, and the stamping and bending process is completed while continuing to move downward.
