Abstract

A one-step forming clamp by forging and stamping belongs to a device used in the arrangement and fastening process of a hydraulic system pipeline. The technical problem to be solved is to provide the double-fixing pipe clamp which has long thread threads and is formed through one-step forming by forging and stamping; the adopted technical scheme is as follows: the one-step forming clamp by forging and stamping comprises fastening bolts, a cover plate, a pipe clamp body and a pipe clamp base; two lug boss holes which are integrated with the pipe clamp base are arranged on the pipe clamp base; inner threads which are matched with the fastening bolts are arranged in the lug boss holes; thread bottom holes of the lug boss holes are flush with the bottom surface of the pipe clamp base; lug bosses and the holes of the positioning pipe clamp are formed at a step, thereby the deviation of the center distance caused by the error of drilling holes and the reduction of matching accuracy of the threads caused by the oversize of the thread bottom holes are put an end to; the organization structure and the mechanical property of metal are improved after the metal is forged and machined; the accuracy and the strength of the threads are increased; and in addition, the matching length of the threads reaches a length of 8-10 thread pitches.

Description

Forging and pressing once-through pipe clamp

Technical field

The utility model forging and pressing once-through pipe clamp belongs to the device that uses in hydraulic system pipeline layout and the fastening process.

Background technique

The device that pipe clamp uses as the hydraulic tubing system operation plays crucial effects in line arrangement and fastening process.The effect of pipe clamp is used for fastening hydraulic pipe line, and it is made up of pipe clamp base, cover plate, pipe clamp body and clamping bolt, in order to the clamping and the fixing hydraulic tube of different tube diameters.Because the size of system pressure is divided into standard series and increases the weight of series, not only because arrange and means of fixation different but also series such as duplex, combination, stack, supporting rail are arranged.The company that produces pipe clamp at present both at home and abroad is numerous, but has only two types pipe clamp from production technology angle market.This pipe clamp of two types is distinguished main on the mentality of designing and preparation process of base plate, is divided into welded nut formula base plate and punching press, drilling and tapping formula base plate.

The screw-thread fit length of welded nut formula base plate is longer; Can reach 7-8 pitch, but welded nut receives many factor affecting in process of production, unstable like welding current; The unclean weld strength that causes of face of weld does not reach, and causes in use receiving coming off easily in external force or the pipeline shake.Punching press, drilling and tapping formula base plate can not come off in order to the boss of positioning pipe clamp; But screw-thread fit length is too short, has only 3 pitch at most, causes screw thread dropout in the fastening process easily; Or because the punching press boss forms plastic deformation, stress is concentrated the disappearance that causes the pipe clamp function.

Summary of the invention

The utility model has overcome the deficiency of existing technology, and the two solid pipe clamp of the long forging forming of a kind of reach is provided.

In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: forging and pressing once-through pipe clamp comprises clamping bolt, cover plate; Pipe clamp body and pipe clamp base; The pipe clamp base is provided with two boss holes with pipe clamp base one, in said boss hole, has the internal thread that matches with clamping bolt, the thread Pilot hole of said boss hole and pipe clamp base end face flush.

The beneficial effect that the utility model compared with prior art has is: the boss and the hole once-through of location pipe clamp, deviation of centre distance and the thread Pilot hole quality of fit that reduces screw thread bigger than normal that the error of having stopped to hole causes.Metal has improved its Organizational Structure and mechanical property after forging processing, strengthened the precision and the intensity of screw thread, and screw-thread fit length reaches 8-10 pitch in addition.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the plan view of Fig. 1.

Fig. 3 is the user mode structural representation of pipe clamp base.

1 is that pipe clamp base, 2 is that boss hole, 3 is that pipe clamp body, 4 is that cover plate, 5 is clamping bolt among the figure.

Embodiment

Shown in Figure 2 like Fig. 1; Forging and pressing once-through pipe clamp comprises clamping bolt 5, cover plate 4; Pipe clamp body 3 and pipe clamp base 1; It is characterized in that: pipe clamp base 1 is provided with two boss holes 2 with pipe clamp base 1 one, in said boss hole 2, has the internal thread that matches with clamping bolt 5, the thread Pilot hole of said boss hole 2 and pipe clamp base 1 bottom surface flush.

As shown in Figure 3, when forging and pressing once-through pipe clamp used, clamping bolt 5 passed cover plate 4, and pipe clamp body 3 is fixed in the boss hole 2 on the pipe clamp base 1; Clamping has pipeline in pipe clamp body 3.

Pipeline can be water pipe, tracheae, various liquid line, and the material of pipeline can be metal tube or nonmetallic pipe.

Combine accompanying drawing that the embodiment of the utility model has been done detailed description above; But the utility model is not limited to the foregoing description; In the ken that those of ordinary skills possessed, can also under the prerequisite that does not break away from the utility model aim, make various variations.

Claims

1. forge and press the once-through pipe clamp; Comprise clamping bolt (5); Cover plate (4), pipe clamp body (3) and pipe clamp base (1) is characterized in that: pipe clamp base (1) is provided with two boss holes (2) with pipe clamp base (1) one; In said boss hole (2), have the internal thread that matches with clamping bolt (5), the thread Pilot hole of said boss hole (2) and pipe clamp base (1) bottom surface flush.
