Abstract
The utility model relates to a special split-type core shaft for a pipe bending machine, which is characterized in that the front part of a core shaft main body is provided with a copper sleeve; the core shaft is in interference fit with the copper sleeve; and the core shaft and the copper sleeve are connected by two Phi4 pins. The special split-type core shaft saves cost and reduces the reject rate of products.
Description
Technical field:
The utility model relates to the special-purpose split type mandrel of a kind of bending machine, is used for the processing of automobile exhaust system bend pipe.
Background technology:
Original bend pipe mandrel is a monoblock type, adopts No. 45 iron material, and the anterior serious wear of mandrel can not be used after use a period of time, and mandrel is all scrapped.
This kind mandrel is the manufacturing cost height not only, and the adhesion that rubs easily of irony mandrel surface and stainless steel inside pipe wall, causes the mandrel surface to produce burr, produces waste product in the bend pipe process.
Summary of the invention:
The purpose of this utility model is to provide a kind of bending machine special-purpose split type mandrel, and it adopts split type mandrel, increases by a copper sleeve in the mandrel body front part, and copper sheathing uses the wearing and tearing back only to need to change, and main body can also continue to use.The friction adhesion can not take place with stainless steel pipe in the copper sheathing surface in addition, reduces the percent defective of bend pipe.
The technical solution of the utility model is achieved in that the special-purpose split type mandrel of bending machine, and it is characterized in that: the front portion of mandrel main body is equipped with copper sheathing, mandrel and copper sheathing interference fit, and mandrel connects with the pin of copper sheathing with two φ 4.
Good effect of the present utility model is to save the mandrel cost, reduces the product percent defective.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1, the special-purpose split type mandrel of bending machine, it is characterized in that: the front portion of mandrel 1 main body is equipped with copper sheathing 2, mandrel 1 and copper sheathing 2 interference fit, and mandrel 1 connects with the pin of two φ 4 of copper sheathing 2 usefulness.
The mandrel main body adopts No. 45 materials to make, at the anterior copper sheathing that increases of mandrel, and mandrel and copper sheathing interference fit, and two pins connections with two φ 4, copper sheathing uses the wearing and tearing back only need change, and beats pin more again and connects, and continues to use.
Claims (2)
1. the special-purpose split type mandrel of bending machine, it is characterized in that: the front portion of mandrel (1) main body is equipped with copper sheathing (2), mandrel (1) and copper sheathing (2) interference fit.
2. the special-purpose split type mandrel of bending machine according to claim 1 is characterized in that described mandrel connects with the pin of copper sheathing (2) with two φ 4.
