Description

Water expansion forming device

Technical Field

The utility model belongs to the water expansion forming field of pipe fitting is pressed to the card, especially relates to a water expansion forming device.

Background

In order to save labor cost, a robot is usually introduced to operate in the process of mass production, so as to realize automatic production.

At present, a clamping and pressing pipe fitting is usually produced by matching a water expansion machine with a die, a clamping and pressing pipe fitting made of a blank pipe fitting after water expansion forming is tightly attached to a die cavity of the water expansion machine, and the clamping and pressing pipe fitting needs to be taken out of the die cavity with certain force. And the robot has limited material taking mode and product grabbing force, so that the automatic production of the pipe fitting clamping and pressing cannot be completely realized.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, it is necessary to provide a water-swelling molding device having an automatic mold release function.

The utility model provides a water bloated forming device, this water bloated forming device includes:

the water expansion machine comprises a water expansion machine support, a left punch, a right punch, a horizontal feeding cylinder and a demolding structure.

As an optional implementation manner, a main cylinder of the water expansion machine is arranged on the support of the water expansion machine, water injection channels are arranged at the central axes of the left punch and the right punch, a feed cylinder lock template is arranged on the horizontal feed cylinder, water injection holes are arranged on the feed cylinder lock template, the demolding structure is arranged on the feed cylinder lock template, and the water expansion mold comprises an upper mold cavity and a lower mold cavity.

As an optional implementation manner, the demolding structure comprises a demolding ejection cylinder, a punch fixing block, a punch bottom plate, an upper stop block and a punch fixing block guide pressing strip.

To sum up, the utility model provides a water bloated forming device includes water bloated machine and water bloated mould, water bloated machine is including water bloated machine support, left drift, right drift, horizontal feed jar and demoulding structure, demoulding structure includes the ejecting hydro-cylinder of drawing of patterns, drift fixed block, drift bottom plate, goes up dog and drift fixed block direction layering, and after water bloated forming device die sinking, through the ejecting drift fixed block of the ejecting hydro-cylinder of drawing of patterns, left drift and right drift have been raised, make the product of hugging closely the lower mould chamber break away from the lower mould chamber, it is limited to have overcome the robot and have got the material mode and snatched the dynamics of product, can't make the product follow the defect that the model chamber breaks away from, has reached and has made things convenient for the robot to snatch the product, can realize the automated production of card pressure pipe fitting, effectively improve production efficiency.

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the scope of the invention, as claimed.

fig. 2 is a schematic view of the water expansion forming device according to the embodiment of the present invention in a mold opening state;

fig. 3 is an E-E sectional view of the water-swelling forming device according to the embodiment of the present invention.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Referring now to fig. 1 and 2, the utility model relates to a water expansion forming device is applied to the water expansion forming field of card pressure pipe fitting. The water expansion forming device comprises a water expansion machine 1 and a water expansion die 2, wherein the water expansion machine 1 comprises a water expansion machine support 11, a left punch 12, a right punch 13, a horizontal feeding cylinder 14 and a demoulding structure 15. The water expansion machine support 11 is provided with a water expansion machine main cylinder 110, central shafts of the left punch 12 and the right punch 13 are respectively provided with a water injection channel, the horizontal feeding cylinder 14 is provided with a feeding cylinder locking template 16, the feeding cylinder locking template 16 is provided with a water injection hole, the demolding structure 15 is arranged on the feeding cylinder locking template 16, and the water expansion mold 2 comprises an upper mold cavity 21 and a lower mold cavity 22.

Referring now to fig. 3, the knockout structure 15 includes a knockout ejection cylinder 150, a punch fixing block 151, a punch bottom plate 152, an upper stopper 153, and a punch fixing block guide bead 154.

The working process of the water expansion forming device is as follows: the product blank pipe fittings are placed into die

cavities

21 and 22, a water expansion machine main cylinder 110 on a water expansion machine support 11 is pressed downwards to enable a die 2 to be matched, a left punch 12 and a right punch 13 are synchronously pushed to reach a water sealing level to seal two ends of the blank pipe fittings, and a horizontal feeding cylinder 14 fills water into the blank pipe fittings through water injection channels in the left punch 12 and the right punch 13 to pressurize.

After the pressure in the blank pipe reaches a certain value, the horizontal feeding cylinder 14 releases the pressure, the main cylinder 110 of the water expansion machine drives the upper die cavity 21 and the lower die cavity 22 to be separated in a return stroke, the demolding ejection cylinder 150 ejects the punch fixing block 151, the left punch 12 and the right punch 13 are lifted, a product tightly attached to the lower die cavity 22 is separated from the lower die cavity 22, a robot can conveniently grab the product, the robot keeps grabbing action after the robot grabs the product, the left punch 12 and the right punch 13 return, the ejection cylinder 150 resets, the robot grabs the product to a designated position, and a production cycle is completed.
