Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and more specifically to a bending side positioning device for a bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. [1] It is divided into manual bending machines, hydraulic bending machines and CNC bending machines. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench consists of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base consists of a base shell, a coil and a cover plate. The coil is placed in the recess of the base shell, and the top of the recess is covered with a cover plate.

[0003] At present, when using a bending machine to bend sheet metal parts, in order to ensure the accuracy of the bending position, positioning devices are usually set at the front and rear ends of the bending machine to position the sheet metal parts. At the moment when the bending machine bends the sheet metal parts, force will be generated, which may easily cause the sheet metal parts to shift to the side, thereby causing errors in the bending position and affecting the bending quality of the sheet metal parts. In order to improve the bending quality, most of them are manually positioned on the side, which is very inconvenient and has certain safety hazards. In view of this, we propose a bending side positioning device for a bending machine. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a bending side positioning device for a bending machine to solve the technical problem that the current bending machine will generate force when bending a sheet metal part, which may easily cause the sheet metal part to shift toward the side, thereby causing errors in the bending position and affecting the bending quality of the sheet metal part. In order to improve the bending quality, the side positioning is mostly performed manually, which is very inconvenient and has certain safety hazards.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a bending side positioning device of a bending machine, comprising a bending machine body with a positioning assembly detachably mounted on one side;

[0006] The positioning assembly includes a supporting assembly detachably connected to the bending machine body and positioning components movably arranged on both sides of the supporting assembly;

[0007] The supporting assembly comprises a supporting platform with positioning slide grooves centrally provided on both sides;

[0008] The positioning component includes a movable block with a groove body opened inside, a round block is rotatably installed in the groove body, a protrusion is arranged on the top of the outer edge surface of the round block, a rotating shaft is rotatably installed on the top of the protrusion, a torsion spring is arranged at the rotation connection between the rotating shaft and the protrusion, and an arc-shaped clamping arm is arranged on the outer edge surface of the rotating shaft, and the arc-shaped clamping arm is an arc-shaped plate-like structure.

[0009] The utility model designs a positioning component. When the sheet metal part is bent, an arc-shaped clamp arm is provided. The arc-shaped clamp arm and the torsion spring can provide pressure on the end of the sheet metal part, thereby overcoming the force generated when the bending machine bends the sheet metal part, thereby achieving the effect of side positioning through the end limit, which is beneficial to improving the stability of the bending process of the sheet metal part. Moreover, by designing the arc-shaped clamp arm as an arc plate-shaped structure, when the end of the sheet metal part is limited, it is beneficial to achieve double-point limiting through the rotating shaft and the end of the arc-shaped clamp arm, and through the elastic force of the torsion spring, the end of the arc-shaped clamp arm provides tangential pressure to the sheet metal part, thereby further achieving the effect of side positioning through the end limit, further improving the stability of the bending process of the sheet metal part, and solving the problem that the bending machine generates force at the moment of bending the sheet metal part, which easily causes the sheet metal part to deviate toward the side, thereby causing an error in the bending position, affecting the bending quality of the sheet metal part. In order to improve the bending quality, it is now mostly manually positioned on the side, which is very inconvenient and has certain safety hazards.

[0010] Preferably, a positioning slider is centrally arranged on one side of the movable block, and the positioning slider is slidably mounted in the positioning slot.

[0011] Preferably, a second fixing bolt is symmetrically arranged on a side of the movable block away from the positioning slide block, and the second fixing bolt can be screwed out of the movable block and screwed into the supporting platform.

[0012] Preferably, a bending table is fixedly arranged inside the bending machine body, a bending groove is centrally provided on the upper end surface of the bending table, and a movable knife for inserting into the bending groove for bending work is movably installed inside the bending machine body.

[0013] Preferably, a positioning block is arranged at one end of the support platform, and a fixing plate is arranged at one end of the lower end surface of the support platform. A groove is centrally provided on the upper end surface of the support platform, and a ruler is fixedly installed in the groove.

[0014] Preferably, one side of the fixing plate is provided with fixing bolts one end of which can be screwed into the bending machine body in an array, and the bottom of one side of the fixing bolts facing the supporting platform is connected to the supporting platform with a diagonal support plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model designs a positioning component. When the sheet metal parts are bent, an arc-shaped clamp arm is provided. The arc-shaped clamp arm and the torsion spring can provide pressure to the end of the sheet metal part, thereby overcoming the force generated when the bending machine bends the sheet metal parts at the moment, thereby achieving the effect of side positioning through the end limit, which is beneficial to improving the stability of the bending process of the sheet metal parts. The arc-shaped clamp arm is designed as an arc plate-shaped structure, which is beneficial to achieve double-point limit through the rotating shaft and the end of the arc-shaped clamp arm when the sheet metal parts are limited at the end, and the elastic force of the torsion spring enables the end of the arc-shaped clamp arm to provide tangential pressure to the sheet metal parts, thereby further achieving the effect of side positioning through the end limit, further improving the stability of the bending process of the sheet metal parts, and solving the problem that the bending machine generates force at the moment of bending the sheet metal parts, which easily causes the sheet metal parts to deviate toward the side, thereby causing errors in the bending position, affecting the bending quality of the sheet metal parts. In order to improve the bending quality, most of them are manually positioned on the side, which is very inconvenient and has certain safety hazards.

[0017] 2. The utility model also designs a convex block, through which the end of a large sheet metal part can be limited, thereby achieving its stable bending processing, and the end of a small sheet metal part can be limited by an arc-shaped clamping arm, thereby expanding the size adaptation range of the bending machine body for the bending processing of sheet metal parts through the arrangement of the convex block and the arc-shaped clamping arm, and because the positioning component is movably arranged on one side of the supporting assembly, the position of the positioning components on both sides of the supporting assembly can be adjusted to facilitate the positioning effect of the sheet metal parts with special-shaped structures at the ends, further solving the problem that the bending machine will generate force at the moment of bending the sheet metal parts, which may easily cause the sheet metal parts to shift toward the side, thereby causing errors in the bending position, affecting the bending quality of the sheet metal parts. In order to improve the bending quality, most of them are manually positioned on the side, which is very inconvenient and has certain safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS
