Abstract

The utility model relates to an inner clamp for a bend pipe and is characterized in that the clamp is tubular. Positioning disks arranged at the rear end of the clamp protrude out of the clamp. Six clamp blocks arranged at the front end of the clamp are uniformly divided into six flaps and the inner sides of the front clamp blocks of the six flaps are provided with inclined planes. Since the inner clamp adopts an inner expansion clamping mode, the clamping area of a pipe is reduced. The inner clamp is also simple in structure and the cost thereof is saved by 5%.

Description

Anchor clamps in the bend pipe
Technical field
The utility model relates to anchor clamps in a kind of bend pipe, is used for the processing of automobile exhaust system tubulation.
Background technology
Existing bending machine clamping device is an external clamping, and the clamping area is big, and materials used is many; Bent tube technique is widely used in mechanical manufacturing field, and bending machine dolly method of clamping adopts pipe end to add compact form, and this method needs certain area that steps up, and the pipe fitting length that needs is long.
Summary of the invention
The purpose of the utility model is to provide anchor clamps in a kind of bend pipe, and it adopts the internal expanding clamping mode to reduce pipe fitting and clamps area, and is simple in structure.
The technical scheme of the utility model is achieved in that anchor clamps in the bend pipe, it is characterized in that: anchor clamps in a tubular form, the rear end positioning disk is outstanding, six lobe fixture blocks are divided into six lobes at the anchor clamps front end, six lobe fixture block front end fixture block inboards are the inclined-plane.
The good effect of the utility model is that it adopts the internal expanding clamping mode to reduce pipe fitting clamping area, and is simple in structure, practices thrift cost 5%.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further description: as shown in Figure 1; Anchor clamps in the bend pipe is characterized in that: anchor clamps in a tubular form, rear end positioning disk 1 is outstanding; Six lobe fixture blocks 2 are divided into six lobes at the anchor clamps front end, and six lobe fixture block front end fixture block inboards are inclined-plane 3.
As shown in Figure 1, when wheel mould bending pipe fitting, adopt internal expansion type clamping pipe fitting inner; The interior anchor clamps of internal core rod 4 insertion bend pipes that bending machine promotes clamping device move before anchor clamps; Make plug promote six lobe fixture blocks 2 through the inboard inclined-plane 3 of six lobe fixture blocks, clamp pipe fitting in pipe fitting inside with six direction respectively, play and clamp the pipe fitting effect internally to the outside expansion; Positioning disk plays with the bend pipe clip main body and is connected effect; Pipe fitting clamping area is little, and pipe fitting bend pipe stress deformation zone is big, thereby increases stock utilization.
