Abstract

The invention relates to a shaping device for bending and stamping-free reinforcing steel bars, which comprises an upper die and a lower die, wherein the lower die comprises a bottom plate, a guide pillar and a spring, the guide pillar is fixed on the bottom plate, the spring is sleeved on the guide pillar, a floating block for placing the reinforcing steel bars is sleeved on the upper part of the spring, swing pressing blocks for bending the reinforcing steel bars are arranged on two sides of the floating block, and the swing pressing blocks are inwards extruded under the compression of the upper die by the floating block. Compared with the prior art, this device places the reinforcing bar on the slider, goes up the mould and pushes down, and the slider is along guide pillar down motion, presses the protruding little hook on the swing briquetting, makes both sides swing briquetting rotatory, has bent the reinforcing bar, after bending, goes up the mould and returns, and the slider in the middle can bounce, takes out the product, because this device makes hard shaping become bending when the reinforcing bar is bent shaping, has improved the impression on the hard shaping, and the product surface is difficult to form the impression, and the part quality is high.

Description

Shaping device for bending reinforcing steel bar without embossing

Technical Field

The invention relates to a reinforcing steel bar bending device, in particular to a shaping device for bending reinforcing steel bars without stamping.

Background

The reinforcing bars are applied to various building structures, and reinforcing bars of different shapes, such as straight reinforcing bars, U-shaped reinforcing bars, frame-shaped reinforcing bars, etc., are required in the building industry. After the steel bar is formed on the mould, the steel bar needs to be further shaped to meet the requirements of industrial use. Chinese patent CN 203018648U discloses an easy reinforcing bar plastic mould of getting material, including last mould and lower mould, the lower mould include bottom plate, guide pillar, spring, location die cavity and plastic piece, the guide pillar fix on the bottom plate, location die cavity and spring from top to bottom overlap in proper order and establish on the guide pillar, the plastic piece be equipped with two, fix respectively on the bottom plate, be located the both sides of location die cavity, the device can conveniently take out the reinforcing bar of plastic, but the reinforcing bar has the impression easily after bending, influences part surface quality.

Disclosure of Invention

The invention aims to solve the problems and provide a shaping device for bending and stamping-free reinforcing steel bars.

The aim of the invention is achieved by the following technical scheme:

a shaping device for bending a reinforcing steel bar without stamping comprises an upper die and a lower die, wherein the lower die comprises a bottom plate, a guide pillar and a spring, the guide pillar is fixed on the bottom plate, the spring is sleeved on the guide pillar, a floating block for placing the reinforcing steel bar is sleeved on the upper portion of the spring, swing pressing blocks for bending the reinforcing steel bar are arranged on two sides of the floating block, and the floating block enables the swing pressing blocks to be extruded inwards under the compression of the upper die.

The swing pressing block is installed on the bottom plate of the lower die through a pin, and is convenient to install and accurate in positioning.

The swing pressing block is characterized in that a small protruding hook is arranged at the lower part of the swing pressing block, and when the floating block is pressed on the small protruding hook, the swing pressing block swings inwards to squeeze the reinforcing steel bars.

The upper part of the swinging pressing block is provided with the idler wheels, so that the swinging pressing block can swing more favorably.

The two guide posts are arranged and are respectively fixed on the bottom plate.

The guide post is fixed on the bottom plate through a screw.

The concrete theory of operation of this device is, place the reinforcing bar on the slider, and the slider cover is equipped with the spring on two guide posts, and the slider is done the up-and-down motion on the guide post, and after the product was put on the slider, go up the mould and push down, the slider is along the guide post down motion, presses the protruding little hook on the swing briquetting, makes both sides swing briquetting rotatory, has bent the reinforcing bar, and after bending, go up the mould and return, the slider in the middle can bounce, takes out the product. Because the device changes the hard forming into bending when the reinforcing steel bar is bent and formed, the embossing on the hard forming is improved, the embossing is not easy to be formed on the surface of the product, and the quality of parts is higher. The device is simple and convenient to operate, safe and reliable, high in production efficiency and capable of guaranteeing good surface quality of parts.

Detailed Description

The invention will now be described in detail with reference to the drawings and specific examples.

Example 1

A shaping device for bending and stamping-free reinforcing steel bars comprises an upper die 1 and a lower die, wherein the lower die comprises a bottom plate 2, guide columns 4 and springs, the guide columns 4 are fixed on the bottom plate 2, the springs are sleeved on the guide columns 4, the shaping device is characterized in that floating blocks 3 for placing the reinforcing steel bars are sleeved on the upper parts of the springs, the two sides of each floating block 3 are provided with swinging pressing blocks 5 for bending the reinforcing steel bars, the swinging pressing blocks 5 are inwards extruded by the floating blocks 3 under the compression of the upper die 1, the swinging pressing blocks 5 are arranged on the bottom plate 2 of the lower die through pins 7, small convex hooks are arranged at the lower parts of the swinging pressing blocks 5, when the floating blocks 3 are pressed on the small convex hooks, the swinging pressing blocks 5 inwards swing to extrude the reinforcing steel bars, rollers 6 are arranged on the upper parts of the swinging pressing blocks 5, the two guide columns 4 are respectively fixed on the bottom plate 2, and the guide columns 4 are fixed on the bottom plate 2 through screws. The device is used for the bar when not bending to the reinforcing bar is fixed a position with reinforcing bar head, puts on the floating block 3 in the centre, and both sides are the swing briquetting 5 that has the gyro wheel, and when last mould down presses the floating block 3, pushes down again, and the swing briquetting 5 of both sides will inwards rotate this moment, bends the reinforcing bar on the floating block 3, goes up the mould and returns, and the part takes out. Wherein, go up mould, floating block, swing briquetting and gyro wheel and all make by Cr12mov material, need quench and have high rigidity.
