Embodiment Construction

[0018] combine figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 , as further described below:

[0019] An automatic pipe expansion and punching device for pipe fittings, comprising a clamping mechanism for clamping and fixing the middle part of the pipe fittings, and a pipe expansion mechanism and a punching mechanism respectively arranged on both sides of the clamping mechanism, wherein:

[0020] 1) The clamping mechanism has a pair of clamping molds 11 for clamping and fixing the pipe fitting 100, the pair of clamping molds 11 are arranged on the rotating disk 12, and are rotated and transposed by controlling the rotating disk;

[0021] 2) The pipe expansion mechanism includes a pipe expansion die 21 and a pipe expansion cylinder 22 that drives the pipe expansion die to expand the pipe opening. And adjust the distance between the handwheel and the clamping mechanism;

[0022] 3) The punching mechanism includes a piercing die, a pair of fixed blocks (321, 322)...

Abstract

The invention discloses a device for automatically expanding and punching pipe fittings, comprising a clamping mechanism for clamping and fixing the middles of the pipe fittings and a pipe expanding mechanism and a punching mechanism which are respectively arranged on two sides of the clamping mechanism. The clamping mechanism is provided with a pair of clamping dies for clamping and fixing the pipe fittings. The pipe expanding mechanism comprises a pipe expanding die and a pipe expanding cylinder for driving the pipe expanding die to expand the pipe fitting mouth; the punching mechanism comprises a piercing die, a pair of fixing blocks with punching needles and a double-stroke oil cylinder; the piecing die is fixed to a center oil cylinder rod of the double-stroke oil cylinder and is driven by the center oil cylinder rod to be positioned at the pipe fitting mouth; and the fixing blocks are respectively connected with two punching needles, arranged on two sides of the piercing die and driven by an external oil cylinder rod on the double-stroke oil cylinder to slide along the direction vertical to the pipe fittings. By using the device, two ports of the pipe fitting are respectively expanded and punched and the efficiency can be improved.

Description

technical field [0001] The invention belongs to a pipe fitting processing device, in particular to a device capable of respectively expanding and punching two ports of a pipe fitting. Background technique [0002] In the prior art, the processing of the two ports of the pipe fittings, such as pipe expansion or punching, needs to be carried out separately. First, the middle part of the pipe fitting is clamped and fixed, and then the pipe opening at one end of the pipe fitting is expanded with a pipe expansion die, and then the pipe fitting is reshaped by the punching mechanism. The other end of the nozzle is punched to complete the operation. Such processing is inefficient and requires manual intervention. Contents of the invention [0003] In order to make up for the above shortcomings, the present invention provides an automatic pipe expansion and punching device for pipe fittings, which can simultaneously expand and punch the two ports of the pipe fittings respectively,...
