Description

Technical Field

[0001] The utility model relates to the technical field of stamping, and more specifically, to a stamping device used for steel production. Background Art

[0002] Stamping is a forming process that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Stamping steel is widely used in automobiles, tractors, instruments and meters, and household appliances.

[0003] When stamping steel, the workpiece is usually placed on a workbench and then operated manually. However, when processing some longer steel workpieces, the operator needs to manually press to prevent the steel from warping, which is inconvenient to operate and poses a safety hazard. Chinese patent application number CN202223027087.0 discloses a stamping forming fixing and clamping device, which includes a support plate and a stamping table. By placing the steel on the upper surface of the stamping table, the extrusion plate is driven down by the lifting plate, so that the extrusion plate can effectively extrude and fix the steel placed on the upper surface of the stamping table. However, this fixing and clamping device is only suitable for small-sized workpieces with a shorter length, and it is difficult to fix steel workpieces with a longer scale. In addition, when using it, the steel needs to be fixed by a clamping mechanism first, and after one stamping is completed, it needs to be released from the clamping and disassembled, and then moved and adjusted again for the stamping position, which makes the operation very cumbersome.

[0017] Reference Figures 1 to 4 The utility model is further described in detail.

[0018] like Figure 1 As shown, a stamping equipment for steel production includes a workbench 1, a placing table 2 and a stamping mechanism. The placing table 2 and the stamping mechanism are both fixed on the workbench 1. The stamping mechanism is placed on one side of the workbench 1. The stamping mechanism includes a support seat 12, a hydraulic cylinder 13 and a punching head 14. The support seat 12 is fixed on the workbench 1. A connecting plate 15 is fixed on the support seat 12. The hydraulic cylinder 13 is fixed on the connecting plate 15. The output end of the hydraulic cylinder 13 passes through the connecting plate 15 and is fixedly connected to the punching head 14. The output end of the hydraulic cylinder 13 moves downward to make the punching head 14 press down to stamp the steel workpiece.

[0019] like Figure 1 and Figure 4As shown, a fixed frame and a movable frame are provided on the placing table 2, and the fixed frame includes two fixed supports 3 and a first slide bar 4. The fixed supports 3 are all fixed on the placing table 2, and the first slide bar 4 is fixed between the two fixed supports 3. The movable frame 5 includes two movable supports 5 and a second slide bar 6. The second slide bar 6 is fixed between the two movable supports 5, and a slider 51 is fixed at the bottom of the movable support 5. Two slide grooves 7 respectively connected to the sliders 51 for sliding movement are provided on the placing table 2, and a spring 20 is provided in the slide groove 7. One end of the spring 20 is fixedly connected to the inner wall of the slide groove 7, and the other end of the slide groove 7 is fixedly connected to the slider 51. The movable frame can be driven by the spring 20 to approach or move away from the fixed frame, so that the distance between the fixed frame and the movable frame can be conveniently adjusted to adapt to the width of the steel workpiece to limit it.

[0020] like Figure 2 and Figure 3 As shown, two sets of limiting mechanisms are provided on the placement platform 2, and the limiting mechanisms include a first limiting block 8, a second limiting block 9, a connecting rod 10 and a bolt 11. An active cavity is opened on the placement platform 2. The cross-sections of the first limiting block 8 and the second limiting block 9 are both L-shaped. The first limiting block 8 and the second limiting block 9 are symmetrically placed. The bottom ends of the first limiting block 8 and the second limiting block 9 are both placed in the active cavity and are slidably connected to the active cavity. The first limiting block 8 is provided with a first through hole 81 for the first slide bar 4 to pass through, and the first limiting block 8 can slide on the first slide bar 4. The second limiting block 9 is provided with a second through hole 91 for the second slide bar 6 to pass through, and the second limiting block 9 can slide on the second slide bar 6. The second limiting block 9 is provided with a connecting rod 10 that is slidably connected to the connecting rod 10 Hole, one end of the connecting rod 10 is fixedly connected to the first limit block 8, the other end of the connecting rod 10 extends into the connecting hole and is slidably connected to the connecting hole, an opening connected to the movable cavity is provided on the placing table 2, and a threaded hole is provided on the second limit block 9, a bolt 11 extends into the opening and is threadedly connected to the threaded hole, and one end of the bolt 11 is against the first limit block 8, and a receiving plate 21 is fixed between the first limit blocks 8 in the two groups of limit assemblies, and the part to be processed is placed on the receiving plate 21 for convenient stamping operation. By rotating the bolt 11, since the threaded hole on the second limit block 9 is threadedly connected to the bolt 11, the second limit block 9 will move toward the first limit block 8 along the length direction of the connecting rod 10, so as to limit the steel workpiece and prevent the workpiece from shifting.

[0021] The clamping mechanism includes a connecting frame 16, a cylinder 17 and two pressing blocks 18. The cylinder 17 is fixed on the connecting plate 15 and is located on one side of the hydraulic cylinder 13. The connecting frame 16 is N-shaped. The connecting plate 15 is provided with a sliding cavity slidably connected to the connecting frame 16. The two ends of the connecting frame 16 are placed outside the sliding cavity. The two pressing blocks 18 are respectively fixed to the bottom of the two ends of the connecting frame 16. The output end of the cylinder 17 is fixedly connected to the connecting frame 16. Rubber pads 19 are fixed to the bottom of the two pressing blocks 18. The cylinder 17 drives the pressing blocks 18 to press the workpiece downward, which replaces the step of manually pressing the workpiece and improves safety. The rubber pads 19 can buffer the pressing blocks 18 to prevent the workpiece from being compressed and deformed.

[0022] The working principle of the utility model is as follows: when placing a steel workpiece, the bolt 11 can be rotated to make the second limit block 9 away from the first limit block 8, and the springs 20 at both ends are stretched to make the mobile frame away from the fixed frame, so as to facilitate the placement of the steel workpiece. Since the steel workpiece to be stamped is relatively long, the part of the workpiece to be stamped is placed on the receiving plate 21, and the two bolts 11 are rotated to make the two second limit blocks 9 close to the first limit block 8, so that the two sides of the steel workpiece are respectively against the first limit block 8 and the second limit block 9, and the spring 20 is compressed accordingly, and the bottom of the mobile support 5 The slider 51 slides on the slide groove 7, and the mobile frame approaches the fixed frame; the cylinder 17 is started to push the connecting frame 16 to move downward, and the pressure blocks 18 at the bottom of both ends of the connecting frame 16 are pressed tightly on the steel workpiece, and then the hydraulic cylinder 13 is started to press the punch head 14 downward to punch the workpiece; because the workpiece to be processed is long, it may be necessary to move in its length direction and perform multiple punching operations. The cylinder 17 is operated to reset the connecting frame 16 and the pressure block 18, and the two sets of limit mechanisms can be pulled together with the workpiece to move left and right on the slide rod, without the need to disassemble and reposition, thereby simplifying the operation.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
