Description
Technical Field
The invention belongs to the field of water expansion forming of clamping and pressing pipe fittings, and particularly 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.
Disclosure of Invention
In order to solve the above problems, it is necessary to provide a water-swelling molding device having an automatic mold release function.
The invention provides a water expansion forming device, which comprises:
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.
In summary, the water-swelling forming device provided by the invention comprises a water-swelling machine and a water-swelling die, wherein the water-swelling machine comprises a water-swelling machine support, a left punch, a right punch, a horizontal feeding cylinder and a demoulding structure, the demoulding structure comprises a demoulding ejection oil cylinder, a punch fixing block, a punch bottom plate, an upper stop block and a punch fixing block guide pressing strip, when the water-swelling forming device is opened, the punch fixing block is ejected out through the demoulding ejection oil cylinder, the left punch and the right punch are lifted, so that a product tightly attached to a lower die cavity is separated from the lower die cavity, the defects that a robot is limited in material taking mode and product grabbing force, and the product cannot be separated from the die cavity are overcome, the robot is convenient to grab the product, the automatic production of a clamping and pressing pipe fitting can be realized, and the technical effect of production efficiency is effectively improved.
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 invention, as claimed.

Detailed Description
The technical scheme of the invention is further specifically described by the following embodiments and the accompanying drawings.
Referring now to fig. 1 and 2, the present invention relates to a water expansion forming device, which is applied to the field of water expansion forming of pipe fittings. 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 demolding structure 15 includes a demolding ejection cylinder 150, a punch fixing block 151, a punch base 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.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
