Description

Technical Field

[0001] The invention relates to the technical field of mold processing, and in particular to a balancing pier block height adjustment device. Background Art

[0002] The balancing block is a key part widely used in the debugging of stamping dies. By adding or removing shims, the gap between the blank holder and the upper die is adjusted to achieve the pressure required for debugging stamping products. However, the existing balancing block needs to manually add or remove auxiliary parts (shims) to adjust the height, which undoubtedly increases the cost of a part. In addition, the on-site debugging situation is changeable, and the matching relationship between the two parts needs to be repeatedly adjusted. Summary of the invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a balancing pier block height adjustment device, which can realize the autonomous adjustment of the top block height, is simple and convenient to operate, and can greatly improve the speed of on-site debugging.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0005] A balancing pier block height adjustment device comprises a mounting hole arranged on a mold body, a top block with adjustable height is arranged in the mounting hole, a sleeve connection is arranged between the mounting hole and the top block, a first electromagnet is fixedly installed on the bottom surface of the mounting hole, a second electromagnet matching with the first electromagnet is installed at one end of the top block close to the mounting hole, and a gasket is placed at one end of the top block away from the mounting hole.

[0006] Preferably, the set includes an outer sleeve and an inner sleeve, the outer sleeve and the inner sleeve are threadedly connected, a plurality of evenly distributed screws are provided between the outer sleeves for fixing, the screws are located on the upper end surface of the mounting hole, and the inner sleeve is detachably mounted on the outer side wall of the top block.

[0007] Preferably, a slot is provided at one end of the inner sleeve, and a block matching with the slot is provided at one end of the top block away from the mounting hole, so that the inner sleeve and the mounting block are restricted from rotating relative to each other through the cooperation between the slot and the block.

[0008] Preferably, the top block and the gasket are both made of magnet-absorbable materials.

[0009] Preferably, the magnetic poles of the first electromagnet and the second electromagnet on the side close to each other are the same.

[0010] Preferably, the mounting hole and the outer sleeve are provided with a through slot connected to the outside, the mounting hole and the through slot on the outer sleeve coincide with each other, the second electromagnet is provided with a limit block that can move freely in the through slot, and the second electromagnet is adsorbed on one end of the top block close to the mounting hole.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The inner sleeve and the outer sleeve connected by thread in the present invention can cooperate to realize the free adjustment of the height of the top block, which can effectively reduce the application of gaskets, which is conducive to reducing cost investment. At the same time, it has the advantage of simple operation and greatly improves the speed of on-site debugging;

[0013] 2. In the present invention, the first electromagnet cooperates with the second electromagnet and utilizes the principle of mutual repulsion of the same magnetic force. The repulsive force generated between the first electromagnet and the second electromagnet can effectively neutralize the pressure on the top block during the stamping process, and can effectively reduce the possibility of damage to the threads between the inner sleeve and the outer sleeve due to excessive impact force. At the same time, the second electromagnet is adsorbed on one end of the top block to prevent the inner sleeve from separating from the top block under the action of its own gravity, and can magnetize the top block to achieve the purpose of adsorbing the gasket, which can effectively prevent the gasket from separating from the top block;

[0014] 3. In the present invention, a threaded connection is used between the mounting hole and the top block to achieve height adjustment. When the thread is damaged, the thread can be replaced by replacing the inner sleeve or the outer sleeve, avoiding the overall replacement of the mounting hole or the top block, which is beneficial to reducing production costs. At the same time, when the threads on the inner sleeve and the outer sleeve are misaligned due to excessive force, making it impossible to separate the inner sleeve and the outer sleeve, the outer sleeve and the mounting hole can be detachably connected, which facilitates the separation of the top block and the mounting hole and the replacement of the inner sleeve and the outer sleeve.
