Description

Auto parts stamping device

Technical Field

The invention relates to metal stamping, in particular to a stamping device for automobile parts.

Background Art

The existing stamping device can guide the stamped pipe fittings to enter the stamping equipment accurately, and can position the stamping head and the stamped pipe fittings during stamping. No sliding will occur during stamping, making the punching faster and more accurate. However, during use, since the stamping die is fixedly connected to the bottom of the hydraulic cylinder, the position of the stamping die cannot be adjusted. When it is necessary to stamp different positions of the workpiece, the workpiece needs to be removed again and then the entire workpiece needs to be positioned, which wastes a lot of time. When the workpiece is stamped, the plate is often pushed out, causing the plate to collide with the punch of the stamping machine, causing collision damage to the plate or the punch, affecting the stable processing of parts, and a small amount of waste chips will remain on the surface of the support plate during processing, which needs to be cleaned up later.

An extrusion rod is also provided at the bottom of the lifting plate, and an elastic air bag is provided below the extrusion rod and at the bottom of the moving groove. An air guide pipe is connected to the outside of the elastic air bag, and the air guide pipe is connected to the air outlet plate, and the air outlet plate faces the direction of the supporting plate.

Furthermore, positioning plates are arranged on the left and right sides of the connecting plate, a stamping die is arranged in the middle area of the positioning plates on both sides, a threaded tube is arranged on the outer side of the positioning plate, a screw is arranged on the internal thread of the threaded tube, a rotating cover is arranged on the outer end of the screw, and a positioning cover is arranged on the inner end of the screw.

Furthermore, the air outlet plate is provided with a plurality of evenly distributed air outlet holes.

Compared with the prior art, the present invention has the following advantages: the present invention has the characteristics of simple structure, easy adjustment, high efficiency and not easy to damage, specifically:

1. The hydraulic cylinder drives the push rod to move downward, and then the connecting plate and the stamping die are used in conjunction with each other, so that the stamping die can stamp the workpiece on the top of the supporting plate. When the position of the stamping die needs to be adjusted, the screw is driven to rotate inside the threaded tube through the rotating cover, so that the screw drives the positioning cover away from the stamping die. At this time, the sliding rod and the slide groove are used in conjunction with each other to make the stamping die slide at the bottom of the connecting plate. When it moves to the required position, the screw is driven to reverse through the rotating cover, so that the positioning cover is moved to the outside of the stamping die again, and the stamping die is tightened, so as to achieve the effect of being able to adjust the position of the stamping die, thereby improving the efficiency of stamping.

2. When the stamping die is stamping the workpiece, the connecting plate will drive the connecting rod to move downward. At this time, the lifting plate at the bottom of the connecting rod will move inside the moving groove. When the lifting plate moves inside the moving groove, it can maintain stability during stamping. When the lifting plate moves downward, the shock-absorbing spring at its bottom can buffer the stamping die, and the nylon rod moves up and down inside the buffer tube, which can eliminate the generated potential energy, thereby preventing the stamping die from colliding with the plate and the punch of the stamping machine under huge stamping pressure, causing collision damage to the plate or the punch. At the same time, the lifting plate moves inside the moving groove, which can drive the extrusion rod to intermittently squeeze the elastic airbag inside the moving groove, so that the gas inside the elastic airbag is ejected through the air outlet plate outside the air guide tube. Since the air outlet plates are symmetrically distributed on the outside of the support plate, the waste chips generated by the processing can be cleaned and the plate (processed workpiece) can be cooled.

DETAILED DESCRIPTION

The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

As shown in FIGS. 1 to 4 , a stamping device for automobile parts comprises a base 1, a running frame 2 is fixedly installed on the top of the base 1, a controller 3 is installed on the outside of the base 1, a supporting plate 4 is installed below the running frame 2, a stamping mechanism 5 is installed on the running frame 2, the stamping mechanism 5 is connected to a buffer cooling mechanism 6, and the buffer cooling mechanism 6 is connected to the base 1, specifically:

Stamping mechanism 5

The hydraulic cylinder 51 includes a hydraulic cylinder 51, a push rod 52 is provided at the bottom of the hydraulic cylinder 51, the hydraulic cylinder 51 is vertically mounted on the top of the running frame 2, the top of the running frame 2 is opened, the push rod 52 passes through the opening and is connected to the connecting plate 53, the bottom of the connecting plate 53 has a slide bar 56, and positioning plates 57 are provided on the left and right sides of the connecting plate 53. The positioning plate 57 in FIG. 3 is in the shape of a "7", that is, the positioning plate 57 includes a horizontal section and a vertical section, a through hole or a threaded hole is provided on the vertical section, and a threaded tube 58 is provided on the outer side of the vertical section. A screw rod 59 is arranged in the corrugated tube 58, and the screw rod 59 is threadedly matched with the threaded tube 58. A rotating cover 510 is provided on the outer side of the screw rod 59, and a positioning cover 511 is provided on the inner side of the screw rod 59. A stamping die 54 is arranged between the two positioning plates 57. The rotating cover 510 is twisted to push the spacing of the positioning cover 511 closer or farther, so as to tighten or loosen the stamping die 54. A slide groove 55 is provided on the top of the stamping die 54, and the stamping die 54 is installed below the connecting plate 53 through the slide groove 55 and the slide rod 56.

The controller 3 is electrically connected to the hydraulic cylinder 51. The hydraulic cylinder 51 is started through the controller 3, and the hydraulic cylinder 51 drives the push rod 52 to move downward. Then, through the cooperation of the connecting plate 53 and the stamping die 54, the stamping die 54 stamps the workpiece on the top of the supporting plate 4. When the position of the stamping die 54 needs to be adjusted, the screw 59 is driven to rotate inside the threaded tube 58 through the rotating cover 510, so that the screw 59 drives the positioning cover 511 away from the stamping die 54. At this time, the stamping die 54 slides at the bottom of the connecting plate 53 through the cooperation of the slide bar 56 and the slide groove 55. When it moves to the required position, the screw 59 is driven to reverse through the rotating cover 510, so that the positioning cover 511 moves to the outside of the stamping die 54 again, and the stamping die 54 is tightened, which has the effect of being able to adjust the position of the stamping die 54, thereby improving the stamping efficiency.

Buffer cooling mechanism 6

Including connecting rods 61, in order to ensure stability during buffering, the number of connecting rods 61 is at least four, and six is optimal. More connecting rods will increase manufacturing costs, and there will be excessive rigidity. The recoil during stamping will damage the entire machine and reduce the service life of the entire machine, or cause the nuts to partially loosen and shorten the maintenance cycle of the entire machine. The number of connecting rods 61 in the figure is four, two on each side, and the connecting rod 61 is in the shape of a "7", that is, it includes a horizontal section and a vertical section. The rear end of the horizontal section is connected to the front and rear ends of the connecting plate 53, and the front end of the horizontal section and the upper end of the vertical section are an integrated structure. The angle between the horizontal section and the vertical section is 90°±3°. The horizontal section and the vertical section are designed to be at right angles in order to establish a barrier zone for the shock wave. The shock wave transmitted from the lifting plate 62 needs to make a 90° turn when passing through the horizontal section and the vertical section, which in disguise slows down or reduces the vibration effect.

The lower end of the vertical section is connected to the top of the lifting plate 62. The lifting plate 62 is set in the movable groove 63 for sliding up and down. The movable groove 63 is vertically installed on the base 1. Two buffer tubes 64 are set at the lower part of the movable groove 63. Nylon rods 65 are movably set in the buffer tubes 64. Shock-absorbing springs 66 are sleeved on the nylon rods 65. The bottom end of the shock-absorbing spring 66 is against the top of the buffer tube 64, and the top end of the shock-absorbing spring 66 is against the bottom end of the lifting plate 62.

When the stamping die 54 stamps the workpiece, the connecting plate 53 will drive the connecting rod 61 to move downward. At this time, the lifting plate 62 at the bottom of the connecting rod 61 will move inside the moving groove 63. When the lifting plate 62 moves inside the moving groove 63, the stamping die 54 can maintain stability during stamping. At the same time, when the lifting plate 62 moves downward, the shock-absorbing spring 66 at its bottom can buffer the stamping die 54. The nylon rod 65 moves up and down inside the buffer tube 64, which can eliminate the potential energy generated, and can prevent the stamping die 54 from causing the plate to collide with the punch of the stamping machine under huge stamping pressure, causing collision damage to the plate or the punch.

The lifting plate 62 moves inside the movable groove 63, and can drive the extrusion rod 67 to intermittently squeeze the elastic airbag 68 inside the movable groove 63, so that the gas inside the elastic airbag 68 is ejected through the air outlet plate 610 outside the air guide pipe 69. The ejected gas can clean up the waste chips generated by the processing and cool the plate at the same time.

In order to reduce the situation where the end face of the buffer tube 64 is deformed due to the impact force directly acting on the end face of the buffer tube 64 when the lifting plate 62 descends, thereby affecting the lifting and lowering of the lifting plate 62, it is preferably designed that the height of the elastic airbag 68 is greater than the height of the buffer tube 64, so that the elastic airbag 68 contacts the lifting plate 62 before the buffer tube 64, thereby reducing and mitigating the direct impact of the lifting plate 62 on the end face of the buffer tube 64, thereby increasing the service life of the buffer tube 64.

In order to prevent the elastic airbag 68 from being blown out due to excessive airflow after being squeezed, causing dust, and to prevent the elastic airbag 68 from being sucked into a large amount of dust into the elastic airbag 68 due to excessive suction when the elastic airbag 68 rebounds, it is preferably designed to open a plurality of evenly distributed air outlet holes on the air outlet plate. The airflow blown out by the elastic airbag 68 is dispersed through the air outlet holes to effectively reduce dust. When the elastic airbag 68 rebounds, the airflow enters the airbag from the air outlet holes. The suction force generated by each air outlet hole is small, which can prevent dust from being sucked into the elastic airbag 68.

The size of the extrusion rod 67 in the figure can be adjusted. Some waste chips with a large amount or a heavy weight can be purged and cleaned with a larger airflow, and the waste chips will not be blown to the outside of the machine and cause secondary pollution to the environment. On the contrary, some waste chips with a small amount or a light weight need to be purged and cleaned with a smaller airflow to prevent the waste chips from being blown to the outside of the machine or into the parts of the machine.

It should also be noted that the extrusion rod 67 cannot be replaced by the lifting plate 62, that is, the elastic airbag 68 is directly pressed by the bottom of the lifting plate 62. The high-frequency up and down movement of the lifting plate 62 will generate heat, and directly pressing the elastic airbag 68 will cause damage to the elastic airbag 68 or significantly reduce its service life.

The above description only describes the specific implementation mode of the present invention. Various examples do not limit the essential content of the present invention. After reading the description, ordinary technicians in the relevant technical field can modify or deform the specific implementation modes described above without departing from the essence and scope of the invention.
