Description

Multi-stroke bending and avoiding slide block mechanism

Technical Field

The utility model relates to a sheet metal material technical field that bends especially relates to a multi-stroke is bent and is kept away a slider mechanism.

Background

Bending, namely, a metal plate is subjected to elastic deformation under the pressure of an upper die or a lower die of a bending machine, then enters plastic deformation, and is freely bent at the beginning stage of plastic bending, along with the pressure applied to the plate by the upper die or the lower die, the plate is gradually close to the inner surface of a V-shaped groove of the lower die, the curvature radius and the bending force arm are gradually reduced, the pressing is continued until the stroke is ended, so that the upper die and the lower die are in full contact with the plate in a close three-point manner, and the V-shaped bending is finished at the moment, namely the bending is commonly known.

The bending and avoiding slide block mechanism in the prior art has the following problems:

1. the slide block at the position close to the front side turning punching hole has a longer stroke, so that the strength of the insert is weaker;

2. the product size accuracy can not be guaranteed.

Therefore, it is desirable to design a multi-stroke bending and avoiding slider mechanism to solve the above problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the longer stroke of the slider that openly turns over to punch a hole more closely that exists among the prior art, lead to mold insert intensity weaker, can not guarantee the accurate shortcoming of its product size, and the multi-stroke that proposes is bent and is kept away a slider mechanism.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a position slider mechanism is kept away in multi-stroke bending, includes fixed plate and bottom plate, the bottom of fixed plate is fixed with the connecting plate, the inside of connecting plate is provided with the head of punching a hole, the bottom of connecting plate is provided with the stripper plate, the top of stripper plate is opened there is the hole flanging, the top of bottom plate is fixed with the base, the inside of bottom plate is provided with the spring, the top of spring is provided with the thimble, the top of thimble is provided with slider two, one side of slider two is provided with slider one, the top of slider one is provided with the product.

Furthermore, a mounting plate is fixed to the top of the fixing plate, and a top plate is fixed to the top of the mounting plate.

Furthermore, the bottom of the bottom plate is provided with a threaded hole, and the internal thread of the threaded hole is connected with a plug screw.

Furthermore, a fixing block is fixed at the bottom of the fixing plate, and a bending punch is arranged on one side of the fixing block.

The utility model has the advantages that: when the product to be bent is subjected to front hole flanging and punching and the bent edge is close to each other and the bent edge needs the slider to avoid the position, the slider is divided into two or more strokes, the slider at the position close to the front hole flanging and punching reduces the stroke to avoid the problem of weaker strength of the insert, so that the front hole flanging and the bending are completed simultaneously, and the product size can be guaranteed to be accurate.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 4, the multi-stroke bending and avoiding slide block mechanism comprises a fixed plate 3 and a bottom plate 9, wherein a connecting plate 4 is fixed at the bottom of the fixed plate 3, a punching head 6 is arranged inside the connecting plate 4, an extrusion plate 5 is arranged at the bottom of the connecting plate 4, a hole flanging 7 is formed in the top of the extrusion plate 5, and the front hole flanging 7 is arranged behind a second slide block 14, so that the fixed position is small, and the stroke needs to be shortened in order to ensure the strength and reduce the volume of the slide block; therefore, when the mold is opened, the first sliding block 15 and the second sliding block 14 move upwards simultaneously, the base 12 is fixed at the top of the bottom plate 9, the spring 11 is arranged inside the bottom plate 9, the ejector pin 13 is arranged at the top of the spring 11, the second sliding block 14 is arranged at the top of the ejector pin 13, when the stroke point of the second sliding block 14 is reached, the second sliding block 14 stops moving, the first sliding block 15 continues moving upwards, the product continues to be jacked upwards, the product 8 is separated from the second sliding block 14 and the first sliding block 15, the product is convenient to take out, the phenomenon that the product 8 is clamped by the main sliding block is avoided, the hole flanging 7 is guaranteed, the bending is completed simultaneously, the size of the product is accurate, the first sliding block 15 is arranged on one side of the second sliding block 14, and the product 8 is arranged at the top of the first sliding block 15.

Further, a mounting plate 2 is fixed on the top of the fixing plate 3, and a top plate 1 is fixed on the top of the mounting plate 2.

Further, the bottom of the bottom plate 9 is provided with a threaded hole, and the inner thread of the threaded hole is connected with a plug screw 10. The plug screw 10 can limit the spring 11.

Further, a fixing block 16 is fixed at the bottom of the fixing plate 3, and a bending punch 17 is arranged on one side of the fixing block 16.

The working principle is as follows: when the die is used, the thimble 13 ejects the slide block in a die opening state, the slide block exits the shape of a product 8, the rear fixing position is larger and the stroke can be increased because the first slide block 15 is fixed with the flanging hole 7 at the fixing position, and the fixing position is smaller because the second slide block 14 is provided with the flanging hole 7 at the front side and the stroke needs to be shortened for ensuring the strength and reducing the volume of the slide block; therefore, when the die is opened, the first sliding block 15 and the second sliding block 14 move upwards simultaneously, when the stroke point of the second sliding block 14 is reached, the second sliding block 14 stops moving, the first sliding block 15 continues to move upwards to jack up a product, and the product 8 is separated from the second sliding block 14 and the first sliding block 15, so that the product is taken out conveniently, the condition that the sliding block is clamped by the product 8 is avoided, the hole flanging 7 is ensured, the bending is completed simultaneously, and the size of the product is accurate.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
