Description

Technical Field

[0001] The invention relates to the technical field of punching die, and in particular to a punching die with a side-smoothing rotary molding mechanism. Background Art

[0002] The die used for stamping is called a stamping die, or simply a die. A stamping die is a special tool for batch processing materials (metal or non-metal) into the required stamping parts. Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes, and profiles to cause plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the required shape and size.

[0003] Stamping is a production technology that uses the power of conventional or special stamping equipment to directly subject sheet metal to deformation force in the die, thereby obtaining product parts with certain shapes, sizes and performances. Sheet metal, die and equipment are the three elements of stamping.

[0004] Because, after the metal or non-metal parts are punched, the stamped parts will be embedded in the die, making it impossible for the stamped parts to be quickly and easily removed, thus affecting work efficiency. Summary of the invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a die mold with a side-straightening rotary molding mechanism, which can quickly and effectively separate the stamping parts in the die so that the next stamping can be carried out, thereby improving work efficiency.

[0006] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0007] A punching die with a side-straightening rotary molding mechanism, comprising a movable die and a driving structure for controlling the movement of the movable die;

[0008] The movable mold is in contact with the slider through a fixed block fixedly arranged below it, and the driving structure is movably connected with the slider through a driving rod;

[0009] A group of pushing mechanisms for pushing the movable mold upward are arranged on both sides of the bottom of the movable mold;

[0010] The two sides of the movable mold are provided with mutually symmetrical pins, and the pins are sleeved with a side fixing block assembly that matches up and down;

[0011] Wherein, the end of the slider is provided with a slider inclined surface, and the fixed block is provided with a fixed block inclined surface which is slidably matched with the slider inclined surface;

[0012] The end of the driving rod is connected with a "concave" shaped rotating bite block, and the "concave" shaped rotating bite block is arranged in the sliding block through a rotating shaft.

[0013] By adopting the above technical solution, the driving structure drives the slider so that the inclined surface of the slider slowly contacts the inclined surface of the fixed block, and the movable mold slides down along with the fixed block. This is the first separation process. At this time, a group of pushing mechanisms are lifted upward by pressure, so that the rear end position of the movable mold is lifted along with the lifting of a group of pushing mechanisms. This is the second separation process. Finally, the movable mold is rotated by the side fixed block combination set on the pin shaft to separate into place, so that the stamping part can be taken out.

[0014] In a preferred example, the present invention may be further configured as follows: the slider is provided with a slider balancing surface, and the fixed block is provided with a fixed block balancing surface that conflicts with the slider balancing surface.

[0015] By adopting the above technical solution, the movable mold can be stably fixed on the slider through the contact between the slider balance surface and the fixed block balance surface, making the whole more stable.

[0017] By adopting the above technical solution, a special nitrogen spring for mold is used, which has the advantages of small size, large elastic force, long stroke, stable operation, precise manufacturing, long service life, gentle elastic curve, and no need for pre-tightening, etc., which simplifies mold design and manufacturing, facilitates mold installation and adjustment, extends the service life of the mold, and ensures the stability of product quality.

[0018] In a preferred example, the present invention can be further configured as follows: a movable position for installing a transverse pushing mechanism is provided on the movable mold, a work table is provided in front of the movable position, and a stop block is provided behind the movable position; a first fixed forming table is provided on the front end of the work table; a second fixed forming table is provided on the work table, the second forming table is in an "L" shape, the left end of which is in conflict with the first fixed forming table and forms an arc surface with the first fixed forming table, and the bottom of the second forming table is fixed on the working table by bolts; a movable forming table is provided on the second forming table, and the movable forming table is fixed on the driving surface of the transverse pushing mechanism by a number of bolts.

[0019] In a preferred example, the present invention can be further configured as follows: the transverse pushing mechanism includes a transverse pushing block body and a return spring mechanism arranged inside the transverse pushing block body; wherein one end of the return spring mechanism abuts against the inside of the transverse pushing block body, and the other end abuts against the side of the work surface.

[0020] By adopting the above technical solution, during operation, the main body of the horizontal push block drives the movable forming table to punch the vehicle body or frame. After the punching is completed, it is reset to the original position through the reset spring mechanism to prepare for the second punching.

[0021] In a preferred example, the present invention can be further configured as: a group of side sliding blocks on the left and right sides of the active position and a group of bottom sliding blocks arranged at the bottom.

[0023] By adopting the above technical solution and designing a group of first movable sheets and a group of second movable sheets, the push block body can slide better in the movable position, wherein the group of first movable sheets and the group of second movable sheets can also discharge the gas generated by the cylinder during the stamping process.

[0024] In a preferred example, the present invention can be further configured as follows: it also includes a group of limit blocks; the group of limit blocks is fixedly arranged on a group of side sliding blocks by a plurality of bolts, wherein one side of the group of limit blocks abuts against the side surface of the transverse push block body.

[0025] By adopting the above technical solution, a group of mutually symmetrical limit blocks are designed, which are arranged on the left and right sides of the horizontal push block body and conflict with it, so as to prevent the horizontal push block body from popping out of the active position after an erroneous operation.

[0027] By adopting the above technical solution, a group of inclined second fixed convex surfaces and a group of inclined movable convex surfaces are designed to be in conflict with each other and matched one by one. During the operation, the movable forming table is in active contact with a group of inclined movable convex surfaces and a group of inclined second fixed convex surfaces through two-point contact, which is more stable and has higher precision.

[0028] In a preferred example, the present invention can be further configured as follows: the side fixing block combination includes an upper fixing block and a lower fixing block; the upper fixing block and the lower fixing block are fixed on the pin shaft in an embracing manner, and a damping sleeve is provided on the pin shaft; wherein the pin shaft is fixed to the side of the movable mold by a plurality of bolts.

This is the second separation process. Finally, the movable mold is rotated and separated into place through the side fixed block combination set on the pin shaft, so that the stamping parts can be taken out. The above-mentioned mechanism can be used to quickly and effectively separate the stamping parts from the die, so that the next stamping can be carried out, thereby improving work efficiency.
