Die clamping bolt and tube pile forming die comprising die clamping bolt

Abstract

The invention relates to a die clamping bolt and a tube pile forming die comprising the die die clamping bolt. A circle of boss is arranged at the upper part of a die clamping bolt rod; a screw thread is sleeved at the lower part of the die clamping bolt rod; a flange-type movable spring seat and a flange inner ring boss-type fixed spring seat are sleeved on the die clamping bolt rod; springs are sleeved on the sleeve walls of the flange-type movable spring seat and the flange inner ring boss-type fixed spring seat; one end of each spring is contacted with the wall of the flange ring of the flange-type movable spring seat; the other end of each spring is contacted with the wall of the flange ring of the flange inner ring boss-type fixed spring seat; a circle of clamping slot is arranged at the lower part of the die clamping bolt rod and at the upper part of the screw thread; an axle steel cable baffle ring is clamping in the clamping slot and is in limited match with the inner ring boss in the flange inner ring boss-type fixed spring seat; a boss die clamping nut is spirally matched with the screw thread at the lower part of the die clamping bolt rod; and a nut clamping seat and the boss die clamping nut are in clamped match. The die clamping bolt has the advantages that: 1, matched joint of the die clamping bolt and the tube pile forming die can be achieved, and the purposes of rapid die sinking and die assembly are achieved; and 2, a die clamping spring is convenient to replace.

Description

technical field [0001] The invention relates to a mold clamping bolt which can not only facilitate the replacement of mold clamping springs, but also has convenient mold clamping or mold opening, and a pipe pile forming mold composed of the mold clamping bolts, belonging to a pipe pile clamping bolt and a pipe pile forming mold. manufacturing field. Background technique [0002] CN101787699A, titled "a pipe die bolt connection structure", comprising a mounting hole arranged in the upper die, a screw hole arranged in the lower die, and a bolt inserted in the mounting hole and connected with the screw hole, it is characterized in that the An outer spring card is installed on the bolt, an inner spring card is installed in the installation hole, a spring is sleeved on the bolt between the outer spring card and the inner spring card, and a bolt head is installed at the installation hole. Its shortcomings: First, the structure of the existing pipe pile forming mold needs to be ch...

AI Technical Summary

Problems solved by technology

Its disadvantages: First, it is necessary to change the structure of the existing pipe pile forming mold, and install a spring sleeve on the clamping edge of the pipe pile forming mold. Not only the manufacturing cost is high, but also the cement slurry can easily enter the spring sleeve, which directly affects the spring. Normal work; Second, because the lower part of the bolt and the edge of the lower die are screwed with threads, not only is the mold clamping screwing difficult and slow, but also the cement slurry enters the thread, which makes it impossible to screw the mold

[0005] The disadvantages of above-mentioned CN102431088A and CN202062504U: because the spring is exposed on the pipe pile forming, when the concrete is distributed on the pipe pile forming mold, the concrete slurry will inevitably fall on it, causing the spring to fail to work normally, and the mold closing or opening die failure
