Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal processing, in particular to an oblique pressing forming stamping die. Background Art
[0002] When stamping some workpieces, due to the limitation of the shape of the workpiece itself, direct stamping cannot be used for processing, because this may cause the workpiece to explode directly, resulting in damage to the product. Therefore, for such workpieces, oblique pressing is generally used for processing. When performing oblique pressing processing, compared with conventional stamping operations, the stamping direction of this method has undergone a spatial change, from vertical stamping to horizontal stamping. In this way, because the force points of the workpiece are concentrated on the stamping position, the workpiece will cause sudden deflection and deformation. If the operator is too close, he or she may be injured.
[0003] Therefore, in response to the above problems, oblique pressing forming stamping dies are now being developed. Utility Model Content
[0004] In order to overcome the disadvantage that the existing device changes from vertical stamping to horizontal stamping, in which the force points of the workpiece are concentrated on the stamping position, which will cause the workpiece to produce sudden deflection and deformation, and the operator is easily injured if the distance is too close, the utility model provides an oblique pressing stamping die.

[0006] In one of the embodiments, an auxiliary material discharge mechanism is further included, and the auxiliary material discharge mechanism includes a guide block, the guide block is connected to the upper front side of the sliding seat, an adjusting screw is threadedly connected to the guide block, and the rear side of the adjusting screw is rotatably connected to a limiting block.
[0007] In one of the embodiments, the mounting base has a rib frame with a triangular prism structure.
[0008] In one embodiment, the right side of the die seat engages with the left side of the punch seat.
[0009] In one embodiment, the protective frame can only be flipped to the right, and the left side of the protective frame is limited by the mounting seat.
[0010] In one embodiment, the front end of the adjusting screw rod is connected with a rotary handle.
[0011] By adopting the above technical solution, the beneficial effects of the utility model are:
[0012] 1. The utility model provides a protective frame capable of unidirectional deflection on the right side of the stamping part to protect against possible unexpected situations during the stamping process of the workpiece, thereby greatly improving the safety of the operator when using the device.
[0013] 2.

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0019] Example 1
[0020] Oblique pressure forming stamping die, such as Figure 1As shown, it includes a base 1, a mounting seat 2 is connected to the upper right side of the base 1, a rib with a triangular prism structure is on the mounting seat 2, a punch seat 3 is connected to the left side of the mounting seat 2, a sliding seat 4 is slidably arranged on the upper left side of the base 1, two springs 5 are connected between the sliding seat 4 and the base 1, a die seat 6 is connected to the right side of the sliding seat 4, and the right side of the die seat 6 is meshed with the left side of the punch seat 3, a hydraulic cylinder 7 is installed on the upper right side of the base 1, the telescopic end of the hydraulic cylinder 7 is arranged to face downward, and a wedge-shaped seat 8 for pushing the sliding seat 4 to move to the right is connected to the telescopic end of the hydraulic cylinder 7, and a protective mechanism 9 for accidental protection against stamping is provided on the mounting seat 2.
[0021] like Figure 1 and Figure 2 As shown, the protective mechanism 9 includes a mounting block 91, and the mounting blocks 91 are connected to the right sides of the front and rear parts of the mounting seat 2. A protective frame 92 is rotatably connected between the mounting blocks 91. The protective frame 92 can only be flipped to the right. The left side of the protective frame 92 is limited by the mounting seat 2. Four torsion springs 93 are connected between the protective frame 92 and the mounting block 91.
[0022] It should be noted that when stamping some workpieces, due to the limitation of the shape of the workpiece itself, direct stamping cannot be used for processing, because this may cause the workpiece to explode directly, resulting in damage to the product. Therefore, in the face of such workpieces, oblique pressing is generally used for processing. When using the present device for oblique pressing, first, the workpiece needs to be inserted between the punch seat 3 and the die seat 6, and then the hydraulic cylinder 7 is started. The telescopic end of the hydraulic cylinder 7 begins to move downward, which will cause the wedge seat 8 to move downward synchronously, thereby pushing the sliding seat 4 to move to the right, and the spring 5 is stretched, thereby causing the die seat 6 to move to the right. In the process of the die seat 6 moving to the right, the workpiece will be squeezed, thereby cooperating with the punch seat 3 to complete the stamping of the workpiece. In this During the process, since the lower part of the workpiece is subjected to the main force, the upper part of the workpiece will produce deflection movement due to stamping. At this time, relying on the cooperation between the protective frame 92 and the torsion spring 93, the workpiece that suddenly produces deflection movement is blocked and buffered to prevent the sudden deflection of the workpiece from causing harm to the operator. In this state, if the workpiece suddenly breaks and flies out, the protective frame 92 can also block and limit the flying workpiece, thereby playing an effective protective role. With the completion of the stamping operation, the telescopic end of the hydraulic cylinder 7 drives the wedge seat 8 to move upward and reset. At this time, the sliding seat 4 is no longer pushed. Under the action of the spring 5, the sliding seat 4 will slide to the left and reset, thereby driving the die seat 6 to move to the left and reset. At this time, the workpiece is no longer clamped by the stamping, and the operator can take out the stamped workpiece.
[0023] Example 2
[0024] On the basis of Example 1, Figure 1 and Figure 3As shown, it also includes an auxiliary material discharge mechanism 10, which includes a guide block 101. The guide block 101 is connected to the upper front side of the sliding seat 4, and an adjusting screw 102 is threadedly connected to the guide block 101. The front end of the adjusting screw 102 is connected to a handle, and the rear side of the adjusting screw 102 is rotatably connected to a limit block 103 for positioning and limiting the position of the workpiece.
[0025] It should be noted that when placing the workpiece, due to the length of the workpiece, after the operator sends the workpiece into the device, the front end of the workpiece will contact the rear side of the limit block 103. At this time, the screw rod 102 can be rotated to adjust the limit block 103 to start moving backward, thereby pushing the workpiece into position so that the workpiece can be stamped in the appropriate position.
[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
