Description

Technical Field

[0001] The utility model relates to the technical field of shipping logistics, in particular to a sheet metal part stamping forming mechanism. Background Art

[0002] Logistics refers to the transportation of goods from one area to another, thereby allocating resources so that all areas can meet various material needs. Logistics is mainly carried out through three types of transportation: vehicle transportation, ship transportation and air transportation, which respectively represent vehicles for land transportation, ships for transportation on rivers and lakes, and airplanes for air transportation. When ships are produced, various sheet metal parts are needed for the outer shells of ships and their equipment. Sheet metal parts need to be sheared, stamped, bent, assembled and other processes during production. Stamping is the use of hydraulic matching molds to press metal sheets into specified shapes.

[0003] For example, a sheet metal stamping device for parts with application number 202321663308.5 includes a base, a stamping assembly is installed on the base, a mechanical arm is installed on the base, a part frame is installed on the base, a support frame is installed on the base, the support frame is located on the top side of the mechanical arm, and a sliding mechanism for sliding cleaning and oil spraying of sheet metal parts on the mechanical arm is installed on the support frame. The utility model, through the arrangement of limiting screw rollers, limiting sliders, gears, continuous tooth plates, etc., realizes that when the mechanical arm takes out the sheet metal parts and places them into the stamping area, the motor is started to drive the limiting slider to slide, so that the connecting shaft rotates during the sliding process, thereby driving the frame plate to rotate during the sliding process, and the injector and the fan are started at the same time, so that in this process, the dust on the surface of the sheet metal is blown off by the fan and the fuel injector sprays the cleaned parts with oil, thereby simplifying the process and improving the convenience of equipment use.

[0004] As shown in the technical solution, some stamping equipment will stamp sheet metal parts into arc shapes, and of course there are other shapes such as triangles. When stamping sheet metal in shapes such as arcs and triangles, the material is placed on the top of the lower die when loading. At this time, the contact surface between the metal sheet and the lower die is a line, or a shape with a narrow top contact surface such as a trapezoid. Unless the staff is skilled in placing the center line of the metal sheet exactly on the center line of the lower die, the metal sheet is likely to slide to the left or right due to uneven weight on the left and right, causing the staff to re-place the metal sheet, which is time-consuming and labor-intensive. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a sheet metal stamping forming mechanism to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a sheet metal stamping forming mechanism, comprising a base, a first spring connected to the inside of the base, and a bracket connected to the top of the first spring, a damper is arranged between the bracket and the base, and a groove is arranged on the top of the base.

[0007] By adopting the above technical solution, six brackets are used to support both sides of the sheet metal, thereby preventing the sheet metal from tilting and sliding to the left or right. When the upper mold is pressed down, the bracket is also forced to retract into the groove, thereby avoiding affecting the forming of the sheet metal and the bracket being broken. When the stamping is completed, the first spring drives the bracket to move up and reset to facilitate the next stamping. At the same time, the upward movement of the bracket pushes the stamped sheet metal upward to facilitate the staff to unload the material. At the same time, the setting of the damper prevents the bracket from moving up too fast and causing the sheet metal to fly away.

[0008] Furthermore, the cross section of the bracket is in an inverted "T" shape, and the bracket is slidably connected to the base.

[0009] By adopting the above technical solution, six brackets are used to support both sides of the sheet metal, thereby preventing the sheet metal from tilting and sliding to the left or right. When the upper mold is pressed down, the bracket is also forced to retract into the groove, avoiding affecting the forming of the sheet metal and preventing the bracket from being broken.

[0010] Furthermore, six of the brackets and six of the first springs are provided, and the six brackets and the first springs are mirror-distributed along the center line of the longitudinal axis of the base.

[0011] By adopting the above technical solution, the staff places the sheet metal on the top of the lower mold. At this time, six brackets are used to support both sides of the sheet metal to prevent the sheet metal from tilting to the left or right and sliding down.

[0012] Furthermore, the dampers are provided in six groups, each group having four dampers, and the six groups of dampers are distributed in a rectangular array.

[0013] By adopting the above technical solution, the first spring drives the bracket to move up and reset to facilitate the next stamping, and the damper is set to prevent the bracket from moving up too fast and causing the sheet metal part to fly away.

[0014] Furthermore, top frames are connected to both sides of the top of the base, and a hydraulic cylinder is installed at the bottom of the top frame. The output end of the hydraulic cylinder is connected to an upper mold through a piston rod, and a lower mold is connected in the middle of the top of the base.

[0015] By adopting the above technical solution, after the hydraulic cylinder is started, the output end drives the upper die to press down through the piston rod. After the upper die is pressed down, it presses against the sheet metal part. Then, as the upper die continues to press down, the sheet metal part is pressed into the shape of the gap between the upper die and the lower die.

[0016] Furthermore, the bracket abuts against the upper mold.

[0017] By adopting the above technical solution, after the hydraulic cylinder is started, the output end drives the upper die to press down through the piston rod. When the stamping is completed, the staff closes the hydraulic cylinder. After the hydraulic cylinder is closed, the output end drives the upper die to move up through the piston rod.

[0018] Furthermore, the upper mold is slidably connected to the top frame.

[0019] By adopting the above technical solution, the upper mold presses down to resist the sheet metal part, and then as the upper mold continues to press down, the sheet metal part is pressed into the shape of the gap between the upper mold and the lower mold. At the same time, the bracket is also forced to shrink into the groove and compress the first spring, thereby avoiding affecting the forming of the sheet metal part and the bracket being broken.

[0020] Furthermore, a pressing block passes through the bottom of the upper mold, and a second spring is connected between the pressing block and the upper mold.

[0021] By adopting the above technical solution, after the hydraulic cylinder is started, the output end drives the upper die to be pressed down through the piston rod. After the upper die is pressed down, it presses against the sheet metal together with the pressure block. At the same time, the pressure block is forced to retract into the upper die and compress the second spring. After the hydraulic cylinder is closed, the output end drives the upper die to move up through the piston rod. At this time, the pressure block is driven downward by the second spring to apply downward pressure to the sheet metal, so as to prevent the sheet metal from fitting tightly with the upper die after stamping and getting stuck in the upper die.

[0022] Furthermore, the middle of the top of the upper mold bulges upward, and both sides of the bulge on the top of the upper mold are connected with ribs, and there are multiple ribs, and the multiple ribs are mirror-distributed along the center line of the longitudinal axis of the upper mold.

[0023] By adopting the above technical solution, the middle of the top of the upper mold is thickened by the bulge on the top of the upper mold, and the structural strength of the upper mold is increased in conjunction with the ribs on both sides thereof, thereby avoiding the phenomenon that the structural strength of the upper mold is reduced and it is easy to break in the middle position after the hole at the bottom of the upper mold is dug to install the pressure block.

[0024] Furthermore, the cross section of the pressing block is in a "T" shape, and the pressing block is slidably connected to the upper die.

[0025] By adopting the above technical solution, after the hydraulic cylinder is closed, the output end drives the upper mold to move upward through the piston rod. At this time, the pressure block is driven downward by the second spring to apply downward pressure to the sheet metal part, so as to prevent the sheet metal part from fitting tightly with the upper mold after stamping and getting stuck in the upper mold.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model supports both sides of the sheet metal part through the arrangement of the bracket, the first spring, the groove and the damper, thereby preventing the sheet metal part from tilting and sliding to the left or right. When the upper mold is pressed downward, the bracket is also forced to retract into the groove to avoid affecting the forming of the sheet metal part and preventing the bracket from being broken. When the stamping is completed, the first spring drives the bracket to move up and reset to facilitate the next stamping. At the same time, the upward movement of the bracket pushes the stamped sheet metal part upward to facilitate the staff to unload the material. At the same time, the arrangement of the damper prevents the bracket from moving up too fast to bounce the sheet metal part off. It effectively prevents the metal sheet from tilting and sliding after being placed, and prevents the sheet metal part from being pressed against the lower mold after stamping to facilitate unloading.

The bracket 6 is slidably connected to the base 1. When the upper mold 4 is pressed down, the bracket 6 is also forced to retract into the groove 8 and compress the first spring 7 to avoid affecting the forming of the sheet metal and the bracket 6 being broken.

After the upper mold 4 is pressed down, it presses against the sheet metal together with the pressure block 10. Then, as the upper mold 4 continues to press down, the sheet metal is pressed into the shape of the gap between the upper mold 4 and the lower mold 5. While the upper mold 4 is pressed down, the bracket 6 is also forced to retract into the groove 8 and compress the first spring 7 to avoid affecting the forming of the sheet metal and the bracket 6 being broken. At the same time, the pressure block 10 is forced to retract into the upper mold 4 to compress the second spring 11. The bulge on the top of the upper mold 4 makes the middle of the top of the upper mold 4 thicker, and cooperates with the ribs 12 on both sides to increase the structural strength of the upper mold 4, so as to avoid the phenomenon that the structural strength of the upper mold 4 is reduced and it is easy to break from the middle position after the hole at the bottom of the upper mold 4 is dug to install the pressure block 10;

[0041] When the stamping is completed, the staff closes the hydraulic cylinder 3. After the hydraulic cylinder 3 is closed, the output end drives the upper mold 4 to move upward through the piston rod. At this time, the second spring 11 drives the pressure block 10 to move downward to apply downward pressure to the sheet metal to prevent the sheet metal from being tightly fitted with the upper mold 4 after stamping and getting stuck in the upper mold 4. At the same time, the first spring 7 drives the bracket 6 to move up and reset to facilitate the next stamping, and the upward movement of the bracket 6 pushes the stamped sheet metal upward to prevent the sheet metal from being tightly fitted with the lower mold 5 after stamping and getting stuck on the top of the lower mold 5, so as to facilitate the staff to unload the material. At the same time, the damper 9 is set to prevent the bracket 6 from moving up too fast and causing the sheet metal to fly away.
