Problems solved by technology

So how to ensure the stability of the stamping mold and improve the production efficiency is an urgent problem to be solved at present. However, artificially increasing the thickness of the gasket of the balance block seriously hinders the intelligent development of the stamping production field of the factory.
[0003] The existing automatic adjustment mold balance block cannot fully realize automatic adjustment, and the adjustment amount cannot be quantified, the operability is extremely poor, and it cannot realize automatic and intelligent adjustment, which is not suitable for the current popular intelligent chemical factories.
[0004] In addition, the accuracy of automatic precision adjustment of the mold gap in the large-tonnage working environment needs to be more than 0.05mm, which also limits the use of automatic adjustment of the mold balance block

Embodiment 1

[0041] Such as Figure 1 to Figure 14 As shown, a self-adjusting mold balance block includes a body 1, a drive mechanism, an adjustment block 3, a safety cover 4, a screw drive pin 5 and a micro servo motor 6; the drive mechanism is spliced ​​by three drive blocks 2 The raised convex conical cylinder has a convex conical surface at the top and a small concave conical surface at the center of the bottom. Guide grooves 21 are provided under each drive block 2, and three guide convex grooves 11 are provided inside the body 1, each Each drive block 2 is connected to a corresponding guide convex groove 11 inside the body 1 through the guide groove 21 below, and each drive block 2 is connected to a corresponding guide convex groove inside the body 1 through the guide groove 21 below. After the groove 11 is installed, the three driving blocks 2 are combined and spliced ​​to form a convex conical cylinder. 1 There are return springs between the inner walls, and the adjusting block 3 ...

Embodiment 2

[0052] Same as the embodiment, the difference is: as image 3 and Figure 4 As shown, six guide pins 17 are fixed on the inner wall of the body 1 .

[0053] The inner wall of the body 1 is provided with six threaded holes, each threaded hole is threaded with a pilot pin 17 .

[0054] Such as Figure 5 and Figure 6 As mentioned above, each driving block 2 is provided with two pilot pin holes 22 .

[0055] The six pilot pins 17 correspond to three drive blocks 2 respectively, that is, every two pilot pins 17 correspond to one drive block 2, and one end of each pilot pin 17 is screwed to one of the inner side walls of the body 1. In the threaded hole, the other end extends into the guide pin hole 22 on the corresponding driving block 2.

[0056] The main body 1 is fixed on the blank holder ring of the mold through the screw mounting hole 12 on it, and the driving block 2 (total 3) is connected with the guiding convex groove 11 on the main body 1 through the guide groove 21 ...

Abstract

The invention belongs to the technical field of automobile stamping dies, and particularly relates to an automatically-adjusted die balance block. A driving mechanism is a convex conical cylinder formed by splicing a plurality of driving blocks, the top of the driving mechanism is a convex conical surface, the bottom of the driving mechanism is a concave conical surface, each driving block is connected to a corresponding guide convex groove in a body in a matched mode through a guide groove in the lower portion, a reset spring is arranged between each driving block and the inner wall of the body, an adjusting block is placed on the driving mechanism, and the concave conical surface at the bottom of the adjusting block is matched with the convex conical surface at the top of the driving mechanism; and a safety cover plate is in threaded connection above the body, a lead screw driving pin is connected with an inner lead screw below the body through an outer lead screw on the lead screw driving pin, the lead screw driving pin penetrates through the body and makes contact with the concave conical surface in the center of the bottom of the driving mechanism, a micro servo motor is connected below the lead screw driving pin in a matched mode, a screw mounting surface is arranged on the outer side of the body, and a screw mounting hole is formed in the screw mounting surface. The intelligent adjustment of the height of the die during stamping production is achieved.

Description

technical field [0001] The invention belongs to the technical field of stamping dies for automobiles, and in particular relates to an automatically adjustable die balance block. Background technique [0002] With the rapid development of the manufacturing industry, the degree of automation of automobile manufacturing is getting higher and higher, and it is transforming from automation to unmanned smart factories. Therefore, higher requirements are put forward for the tooling equipment for the production of automobiles. Among them, in the field of intelligent production of stamping dies, in order to ensure the stable production of stamping dies, it is necessary to install a balance block on the blank holder ring of the stamping die, and realize the high-precision micro-quantity of the balance block by manually increasing or decreasing the thickness of the balance block gasket. Adjust to make the pressure of the mold blank holder more balanced. So how to ensure the stability ...
