Abstract
The utility model discloses an arc forming die for a square tube. The arc forming die comprises a female die and a male die, wherein the female die comprises a bottom plate and a vertical plate which is vertically arranged on the bottom plate; an arc female die forming surface used for forming the arc of a square tube to be machined is formed on a top side face of the vertical plate; and a male die forming surface matched with the female die forming surface is formed on the male die. The arc forming die has excellent wear resistance and high thermal fatigue resistance, is an ideal product special for bending metal pipes and is suitable for bending pipes of various materials such as copper, aluminum and steel, the square tube is smoothly bent in a saturated mode due to the unique arc forming surface; and due to the material quality and machining process parameters, stable performance is ensured, and the service life is long.
Description
Technical field
The utility model belongs to technical field of mold, particularly relates to a kind of radian mould of square tube.
Background technology
According to passenger vehicle and other industrial modeling requirement, support frame all needs to have the tubing of radian.In the prior art, processing metal pipeline or all adopt universal or unidirectional mandrel as bend pipe mould when bending square tube, realizing bending square tube mainly is the ripple pearl that relies on the mandrel, the ripple pearl is along with curved displacement is moving during work, ripple pearl and mandrel are kept at an angle and bend square tube, and the ripple pearl mainly adopts pin to be connected with the connected mode of mandrel.And pin is exactly universal or the critical defect of unidirectional mandrel, and it is subjected to the impact of extraneous environment larger, in the situation that the mouth of pipe, caliber distortion all can cause inserting difficulty and cause that ripple pearl head damages fracture.Therefore, this kind is short service life universal or unidirectional mandrel, directly causes the processing cost of bend pipe high.
Therefore, design a kind of elbow that can extrude various radians, appearance is round and smooth, without pit, and high efficiency, and the radian mould of long-lived square tube has become needing badly of industry.
The utility model content
The purpose of this utility model provides a kind of radian mould of square tube, and this device can extrude the elbow of various radians, and appearance is round and smooth, without pit, and high efficiency, and is durable in use.
The technical solution of the utility model is:
A kind of radian mould of square tube, comprise former and formpiston, it is characterized in that: described former comprises base plate and the riser that is vertically set on the base plate, be provided with the female mould forming face in order to moulding square tube radian to be processed of arc on the top side face of described riser, be provided with the male mould forming face that is complementary with the female mould forming face on the described formpiston.
Preferably, the integral body that is formed in one of the base plate of described former of the present utility model and riser.
Preferably, described former of the present utility model and formpiston all adopt mould steel to process.
Preferably, offer the formpiston installing hole on the top side face of described formpiston of the present utility model, offer the former installing hole on the riser of described former.
The utility model has the advantage of:
It has fabulous wearability, the thermal fatigue resistance ability is strong, is a kind of desirable product that is specifically designed to bending metal tubing.Be applicable to bending of the various material tubing such as copper, aluminium, steel.Its unique arc forming surface makes it more smooth and easy when bending square tube, saturated.The material of itself and working process parameter are guaranteed its stable performance, and service life is longer.
This mould adopts import mould steel to process by Precision Machining and forms, and quality, stable performance, processing effect are good, and manufacturing cost is moderate, its long service life, reduce the processing cost of enterprise, compressed the input of human and material resources, had the extremely strong market competitiveness.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The realization of the utility model purpose, functional characteristics and advantage are described further with reference to accompanying drawing in connection with embodiment.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, a proposition embodiment of the present utility model, as shown in the figure, a kind of radian mould of square tube, comprise former 1 and formpiston 2, described former 1 comprises base plate 3 and the riser 4 that is vertically set on the base plate 3, be provided with the female mould forming face 5 in order to moulding square tube radian to be processed of arc on the top side face of described riser 4, be provided with the male mould forming face 6 that is complementary with female mould forming face 5 on the described formpiston 2.
The integral body that the base plate 3 of described former 1 of the present utility model and riser 4 are formed in one, the globality of former is better like this, and its whole Rigidity and strength is all very superior, and is not yielding, long service life.
Described former 1 of the present utility model and formpiston 2 all adopt mould steel to process, and its quality, stable performance, processing effect are good,
Offer formpiston installing hole 7 on the top side face of described formpiston 2 of the present utility model, offer former installing hole 8 on the riser 4 of described former 1.Such design is convenient to formpiston is installed in the top of hydraulic press, and former is fixed on the lower end of hydraulic press.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
