Description
Technical field
The present invention relates to the perforating tool of piercing mill of seamless steel tube, specially refer to main warp tool--the jockey of top and push rod.
Background technology
Punch is as the most key equipment in the whole tube rolling unit, and the quality of its work all has decisive influence to the quality and the whole unit productivity ratio of finished product.And coming directly towards one of main warp tool as punch, its quality and replacing time directly affect perforation quality and piercing efficiency.The interior water-cooled top of using for the φ 100 of prior art and following unit thereof, as shown in Figure 1: the loose joint 3 that it all is screw thread that top 1 and push rod 2 lean on two ends is connected.The threaded one end of loose joint 3 is connected with push rod 2, and other end screw thread is connected with top 1.During online replacing top, directly unload the top, loose joint also is connected on the push rod, changes a new top then and is screwed in the loose joint.Because of little, the light weight of top specification of prior art, can use clamp to carry out manual installation by the workman, still do not influence the rhythm of production of perforation.
Along with the increase gradually of steel pipe specification, the specification of top and quality have also increased much, and the form that is threaded of the interior water-cooled top of prior art also no longer adapts to high efficiency, large-duty requirement.Because of after the quality of top increases, the workman often can't make the screw thread of top aim at the screw thread of loose joint when the top is installed, and the rotation top is also very difficult during stubborn screw thread.Because the screw thread of top and loose joint is to use tighter and tighter, during dismounting, difficulty is often revolved motionless especially.Narrow and small because of surrounding space again, can not use large-scale extracting tool, change very inconvenient.Generally the push rod band have to the top and change together, so not only increase workload and also taken the production time.
Summary of the invention
Purpose of the present invention is exactly for overcoming the shortcoming of prior art, a kind of Quick Connect Kit of punch top and mandril of perforator is provided, satisfy the requirement of fast online replacement top, enhancing productivity.Simultaneously, this device can be recycled, and has reduced production cost.
Technical scheme of the present invention for achieving the above object is:
A kind of Quick Connect Kit of punch top and mandril of perforator comprises: top, push rod, and the loose joint that connects top, push rod is characterized in that; Described loose joint is made up of top loose joint and push rod loose joint, described top loose joint one end band external screw thread, and the other end is the guiding cone of outer wall belt cannelure, is with an externally threaded end to be connected with the top; Described push rod loose joint one end band external screw thread, the other end are the guiding taper hole that is complementary with described guiding cone, and at its horizontal corresponding pin-and-hole that is provided with described cannelure, are with an externally threaded end to be connected with push rod; The cone of described top loose joint matches with the guiding taper hole of described push rod loose joint, and the cannelure of described top loose joint is provided with alignment pin with the pin-and-hole place of coincidence of described push rod loose joint, in the described alignment pin the tip of the axis aperture split pin is set.
The present invention compared with prior art because top loose joint and push rod loose joint all are the tape guide taperings, can guarantee both quick centerings during installation; Since the bolt-type connected mode need not be online during the replacing top to the rotation of heavy top, reduced workman's workload, saved the replacing time; Because being connected of top loose joint and top, push rod loose joint and being connected of push rod all are to have adopted to be threaded, therefore, push rod loose joint and top loose joint can onlinely be dismantled down, do not influence ordinary production rhythm, and can be installed on the new push rod and reuse, reduce accessory loss.The present invention comes directly towards the push rod Quick Connect Kit, has simplified the step of online replacing top, has reduced the online replacing time, has reduced labor strength, has improved production efficiency, has reduced production cost.
Description of drawings
Fig. 1 is the structural representation that prior art " top with push rod with two ends screw thread loose joint " is connected;
Fig. 2 is a structural representation of the present invention;
The A-A profile of Fig. 3 Fig. 2.
The present invention will be further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As Fig. 2, shown in Figure 3, a kind of Quick Connect Kit of punch top and mandril of perforator comprises: top 1, push rod 2, and the loose joint 3 that connects top, push rod; Described loose joint 3 is made up of top loose joint 3-1 and push rod loose joint 3-2, described top loose joint 3-1 one end band external screw thread, and the other end is the guiding cone of outer wall belt cannelure, is with an externally threaded end to be connected with top 1; Described push rod loose joint 3-2 one end band external screw thread, the other end are the guiding taper hole that is complementary with described guiding cone, and at its horizontal corresponding pin-and-hole that is provided with described cannelure, are with an externally threaded end to be connected with push rod 2; The cone of described top loose joint 3-1 matches with the guiding taper hole of described push rod loose joint 3-2, the cannelure of described top loose joint 3-1 is provided with alignment pin 4 with the pin-and-hole place of coincidence of described push rod loose joint 3-2, in the terminal aperture of described alignment pin 4 split pin 5 is set.
The installation of the present invention and the course of work:
The work that can install under production line: loose joint 3-1 in top is with an externally threaded end to be connected with top 1, and push rod loose joint 3-2 is with an externally threaded end to be connected with push rod 2.More changing jobs on the production line: behind the push rod installation in position, coming directly towards loose joint 3-1 together with top 1, aim at an end of push rod loose joint 3-2 tape guide taper hole with its conical end, insert, after the cannelure center line to the loose joint 3-1 of top and the central lines of push rod loose joint 3-2 pin-and-hole, 2 alignment pin 4 are inserted respectively in 2 pin-and-holes of push rod loose joint 3-2, on the end aperture of alignment pin 4, plugged split pin 5 then, install and to carry out work.When changing the top, take off split pin 5, extract alignment pin 4 out, top loose joint 3-1 and top 1 can integral body be taken off and are changed.After top 1, push rod 2 are scrapped, can pull down top loose joint 3-1 and push rod loose joint 3-2 and continue to use.Because top loose joint 3-1 and push rod loose joint 3-2 use more expensive alloy manufacturing, the recycling use cost that reduces.
