Description

A New Clamping Die for Forming the End of Oil Pipe

technical field

The utility model relates to the field of moulds, in particular to a novel oil pipe end forming and clamping mould.

Background technique

At present, the tightening method adopted by the end forming mold is rigid tightening, which is to achieve tightening through the interference fit between the working surface of the fixture and the outer surface of the pipeline. The surface layer of the new material PP pipe is made of PP material, which has low hardness and cannot be used. Early hard tightening method for processing: At present, we can adopt the following bills: Option 1: Increase the amount of interference, thereby increasing the pressing force on the PP layer to prevent clamping and slipping, Option 2: Change the material of the fixture working surface In order to adjust the friction coefficient and prevent clamping and slipping, for the first solution: because the surface material of the PP pipe is polypropylene, which has certain elasticity, the actual effect obtained by increasing the interference is not obvious, and the large interference will cause the surface of the pipe to clamp Severe scars. For scheme two: A variety of materials were selected for testing, and the results showed that it was impossible to find a suitable material in a short time. Even if a suitable material was found, the service life of the material was short and could not meet the existing production needs.

Therefore, it is necessary to invent a novel oil pipe end forming clamping die to solve the above problems.

Utility model content

The purpose of this utility model is to provide a new clamping mold for forming the end of oil pipe to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a new clamping mold for forming the end of the oil pipe, including a first clamping block, a movable clamping block is arranged on one side of the first clamping block, and the movable clamping block One side of the clamping block is provided with a spring washer, and one side of the spring washer is provided with a second clamping block, and a fixing pin is arranged inside the second clamping block, and the first clamping block and the second clamping block A joint is provided between the clamping blocks, a pier head is provided at one end of the first clamping block, and a PC pipe is provided at the other side of the first clamping block.

Preferably, a first groove is provided on one side surface of the first clamping block.

Preferably, a second groove is provided on one side of the movable clamping block.

Technical effect and advantage of the present utility model:

The utility model effectively improves the die mold by being provided with a first clamping block, a movable clamping block, a spring washer, a second clamping block, a fixed pin, a joint, a pier head, a first groove, and a second groove. The clamping force solves the processing difficulties caused by the large tolerance of the outer diameter of the PP pipe, greatly improves the qualified rate of the end forming of the PP pipe, avoids mechanical damage, and realizes safe production.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model provides a new type of clamping mold for forming the end of the oil pipe as shown in Figure 1-2, which includes a first clamping block 1, and is characterized in that a movable clamp is arranged on one side of the first clamping block 1 Tight block 2, a spring washer 3 is provided on one side of the movable clamping block 2, a second clamping block 4 is provided on one side of the spring washer 3, and a fixing pin is arranged inside the second clamping block 4 5. A joint 6 is provided between the first clamping block 1 and the second clamping block 4, a pier head 7 is provided at one end of the first clamping block 1, and the other side of the first clamping block 1 A PC tube 8 is provided.

Further, in the above technical solution, a first groove 9 is provided on one side surface of the first clamping block 1;

Further, in the above technical solution, a second groove 10 is provided on one side of the movable clamping block 2 .

The working principle of this utility:

With reference to the accompanying drawings 1-2 of the description, when using the utility model, the PC pipe 8 is put on the joint 6, put into the first groove 9 and the second groove 10 in the first clamping block 1 and the movable clamping block 2, Put the joint 6 into the front cavity, turn on the machine switch, adjust the number of spring washers 3, move the movable clamping block 2 and the first clamping block 1 to clamp the PC tube 8, and finally the second clamping block 4 is fixed. The pier head 7 advances and extrudes the PC pipe 8 forward, and the end is formed into a fixed shape. The outer layer of the PC pipe 8 is wrapped with polypropylene, and the hardness of the surface layer is too small to easily produce pinch marks. Because the outer layer is extruded, the outer diameter tolerance zone is relatively large. The tolerance zone of the outer diameter of the PC tube 8 is large, resulting in loose clamping of the mold or severe clamping marks on the outer diameter of the PC tube 8 . Between the movable clamping block 2 and the second clamping block 4 is a spring washer 3. During the clamping process, the spring washer 3 is elastic to compensate for the unqualified end molding caused by the large tolerance zone of the outer diameter of the PC tube 8, effectively The clamping force of the mold is improved, the processing difficulty caused by the large tolerance of the outer diameter of the PP pipe is solved, the qualified rate of the end forming of the PP pipe is greatly improved, mechanical damage is avoided, and safe production is realized.

Finally, it should be noted that: the above is only a preferred embodiment of the utility model, and is not intended to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art , it can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model, All should be included within the protection scope of the present utility model.
