Problems solved by technology

However, the spring seat and nut of this scheme are not fixedly connected to the pipe mold. If there is vibration during mold closing, the spring seat is easy to loosen, resulting in loose connection between the screw rod and the nut, resulting in a free stroke, thereby causing leakage of the pipe mold. The clamping strength of the screw still needs to be improved

Embodiment Construction

[0023] The present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0024] Such as figure 1 As shown, a clamping screw for a pipe mold for producing pipe piles includes an upper fixing seat 1 for fixing with an upper mold and a lower fixing seat 2 for fixing with a lower mold, the upper fixing seat 1 and the lower fixing seat 2 A plurality of screws 3 are respectively provided on the fixing base 2, and a spring 4 is sleeved on the upper fixing base 1, and the bolt 5 is screwed and fixed to the lower fixing base 2 after passing through the spring 4 and the upper fixing base 1 in sequence.

[0025] A guide sleeve 6 is inserted into the end of the spring 4 away from the upper fixing seat 1, and the end of the spring 4 abuts against the guide end surface 7 of the guide sleeve 6. The bolt 5 includes a bolt head 51 and a bolt body 52. ​​The connection between the guide sleeve 6 and the bolt head 51 is provided with a friction ...

Abstract

The invention belongs to the technical field of buildings, relates to the die closing fastener of a pipe die for producing a pipe pile, and aims at solving the technical problem of low bonding strength in the prior art. The die closing fastener comprises an upper fixing seat fixed with an upper die, and a lower fixing seat fixed with a lower die, wherein a plurality of screws are correspondingly arranged on the upper fixing seat and the lower fixing seat; the upper fixing seat is sleeved with a spring; a bolt sequentially passes through the spring and the upper fixing seat to be fixedly screwed to the lower fixing seat. The die closing fastener has the advantages of being high in bonding strength, improving the die closing strength of the pipe die, being small in frictional resistance during die closing, and fast to screw.

Description

Technical field [0001] The invention belongs to the technical field of construction and relates to a clamping screw for a pipe mold for producing pipe piles. Background technique [0002] The pipe pile manufacturing industry belongs to the manufacturing type of heavy industrial production. During the production process of pipe piles, the use of pipe molds plays a decisive role. The pipe mold clamping screws are the most critical part of the pipe mold and play a role in the quality of the pipe piles. Considerable effect. When the pipe mold is missing or not tightened, it will cause defects such as leakage of the pipe pile. Therefore, in the pipe pile industry, further research is being done on the pipe pile clamping screw. . [0003] Chinese patent literature discloses a T-shaped clamping screw [application number: 201020296888.5] consisting of a screw, a spring seat, a spring, and a nut. A spring is sandwiched between the spring seat and the spring seat. One end of the T-shaped sc...
