TECHNICAL FIELD

[0001] The utility model belongs to punch die technical field relates to a kind of multi-face punch die of metal sheet. BACKGROUND

[0002] The processing of metal parts is usually produced using a punch die, which is a die installed inside a punch press. The upper die holder in the die is moved up and down by the punch press machine table. When it moves down, it presses the upper die holder, causing the bottom of the upper die holder to extrude the top of the lower die holder, thereby deforming the metal part placed between the upper and lower die holders and forming the desired metal part structure.

[0003] However, the existing punch die still has some shortcomings. For metal sheets with "L" shaped bending structure, when a convex shape needs to be punched on the sheet, only the structure on one side can be punched at a time. Therefore, the sheet needs to be removed, turned over and punched again, which reduces the production efficiency. SUMMARY

[0006] In the scheme, the metal plate is placed at the upper and lower forming surfaces, when the mold is closed, the upper die holder drives the upper inclined guide plate to move downward, the upper inclined surface at the bottom of the upper inclined guide plate abuts against the lower inclined surface at the top of the lower inclined guide plate, the upper inclined guide plate pushes the lower inclined wedge, the lower inclined wedge and the lower insert to move left, and at the same time, the inclined slide block is inserted into the inclined slide rail during the vertical downward movement of the upper die holder, pushing the left inclined wedge and the left insert to move right, clamping the left and right sides of the lower forming surface, and finally the upper pressing plate moves above the lower insert, clamping the upper and lower sides of the upper forming surface, stamping the multiple surfaces of the metal plate to form the required part structure; through the above-mentioned mode, only one stamping process is needed for the metal plate to complete the structure stamping on the plate, thereby improving the production efficiency.

[0007] In the above-mentioned multi-surface stamping die for metal plate, a limit block is arranged at the bottom of one side of the lower inclined wedge close to the lower inclined guide plate, and a nitrogen gas spring is arranged at the bottom of the other side of the lower inclined wedge, and one end of the nitrogen gas spring abuts against the lower die holder. The nitrogen gas spring is used for resetting the lower inclined wedge to move to the rightmost side, and the limit block is arranged at the right side of the lower inclined wedge and can abut against the lower die holder, thereby limiting the lower inclined wedge and preventing collision during the resetting process.

[0008] In the above-mentioned multi-surface stamping die for metal plate, the upper inclined guide plate can abut against the lower inclined guide plate in the horizontal direction. After the upper inclined guide plate pushes the lower inclined guide plate to move left, the upper inclined guide plate continues to move to the right side of the lower inclined guide plate and abut against the lower inclined guide plate, so that the lower inclined wedge does not move right during stamping, thereby improving the stamping precision.

[0009] In the above-mentioned multi-surface stamping die for metal plate, a horizontal first slide rail is arranged between the lower inclined wedge and the lower die holder, and a horizontal second slide rail is arranged between the left inclined wedge and the lower die holder. The first slide rail and the second slide rail are arranged on the lower die holder to connect the lower inclined wedge and the left inclined wedge respectively, so that the lower inclined wedge and the left inclined wedge can slide horizontally on the lower die holder.

[0010] In the above-mentioned multi-surface stamping die for metal plate, the upper pressing plate, the lower insert and the left insert are respectively detachably mounted on the upper die holder, the lower inclined wedge and the left inclined wedge. The connection part of the upper pressing plate, the lower insert and the left insert is provided with a surface for forming a stamping structure, and the above-mentioned structure is detachably mounted. When it is necessary to replace the structure of the stamping product, only the upper pressing plate, the lower insert and the left insert need to be replaced, thereby reducing the production cost.

[0011] In the above-mentioned multi-surface stamping die for metal plate, a fixed guide column is arranged on the lower die holder, and the guide column is inserted into the upper die holder and is in sliding connection. The guide column plays a guiding role when the mold is closed, so that the upper die holder can be accurately butted against the lower die holder.

[0012] In the multi-surface stamping die for metal plate material, the side wall of the lower die base is provided with a plurality of sliding grooves which are arranged obliquely downward.

[0013] Compared with the prior art, the utility model has the advantages of:

[0014] 1、In this scheme, the upper inclined guide plate pushes the lower inclined guide plate, the lower inclined wedge and the lower insert block to move left, the inclined sliding block is inserted into the inclined sliding rail, the left inclined wedge and the left insert block are pushed to move right, the left and right sides of the lower forming surface are clamped, the upper pressing plate moves above the lower insert block, the upper and lower sides of the upper forming surface are clamped, the multi-surface of the metal plate material is stamped, and the required part structure is formed, since only once stamping processing is needed to the metal plate material, the structure stamping on the plate material can be completed, and the production efficiency is improved.

[0015] 2、In this scheme, the nitrogen spring pushes the lower inclined wedge to move right to reset, the lower inclined wedge moves to the rightmost side of the first sliding rail, the limiting block is arranged at the right side of the lower inclined wedge, can abut against the lower die base, and has the limiting effect to the lower inclined wedge, so that the lower inclined wedge and the lower die base are prevented from colliding in the resetting process.
