Abstract
The utility model discloses a universal spindle with a hard alloy head, and relates to the field of pipe bending machine equipment. The universal spindle consists of a spindle rod (1), a pressing screw (2), a spring (3), a pin (4), a swing round ball (5) and a swing rod (6), wherein the spindle rod (1) is provided with the pressing screw (2), the spring (3) and the pin (4) from left to right respectively; the swing rod (6) is arranged on the right side of the pin (4); and one end of the swing rod (6) is connected with the swing round ball (5) outside the spindle rod (1). The wear resistance of hardness of a main working surface of the universal spindle is greatly improved, the influence of a chromium plated universal spindle and a chromium plated swing round ball on the quality of a bend pipe of the equipment due to texturing or plating stripping in an inner hole of a copper pipe and an aluminum pipe is avoided, the service life of the universal spindle is greatly prolonged and is twenty times the life of the transmission universal spindle, the debugging time is shortened, and the quality consistency of bending of the bend pipe is improved.
Description
Technical field:
The utility model relates to the bending machine apparatus field, relates in particular to the universal mandrel of hard alloy head.
Background technology:
Be installed in the universal mandrel on the bending machine, universal ball end and the mould on the equipment through swing cooperate and carry out bend pipe, equipment in the bend pipe course of work, bend pipe at every turn; The swing ball is all wanted crooked certain angle, cooperates the bending of pipe, and swing ball and can prevent effectively that the tube bending position from curving the flat tube shape, and bend pipe each time; From pipe universal mandrel is put in the pore after the brake forming, in the process of taking out, the swing ball all will with the tube wall friction; When particularly taking out after the bending, frictional force is bigger, so the ball position is universal mandrel position the most easy to wear; Traditional universal mandrel swing ball is the steel part material, and after quenching, chrome-faced comes to increase wearability and surface smoothness again; But this universal mandrel is all scrapped because the swing circle ball wear is serious after with a period of time; At present domestic in addition also have some your pupil's business mens immature because of technology, and the moving angle of the universal mandrel swing circle spherical pendulum of processing is not enough, swings dumb; Also not wearing and tearing, the swing neck fractures, and this product is low product inferior.
The utility model content:
The purpose of the utility model provides the universal mandrel of hard alloy head; It has greatly improved the wearability of the hardness on universal mandrel groundwork surface, has avoided universal mandrel rod of chromium plating and chromium plating swing ball because of with copper pipe, aluminum pipe endoporus plucking or coating scaling and influence the quality of equipment bend pipe; Greatly improved the service life of universal mandrel; Be about more than 20 times of universal mandrel life-span of transmission service life, reduced adjusting machine time, improve the crooked quality conformance of bend pipe.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it is made up of mandrel rod 1, housing pin 2, spring 3, pin 4, swing ball 5, swing arm 6; Be respectively arranged with housing pin 2, spring 3 and pin 4 in the mandrel rod 1 from left to right, the right side of pin 4 is provided with swing arm 6, and an end of swing arm 6 is connected with mandrel rod 1 outside swing ball 5.
Described swing ball 5 adopts Hardmetal materials to process for georama designs, and has high rigidity, the effect of high-wearing feature.
The sphere diameter of described swing ball 5 is S ￠ 3-S ￠ 30.
Stick together through gluing between described swing arm 6 and the swing ball 5.
The utility model has greatly improved the wearability of the hardness on universal mandrel groundwork surface; Avoided universal mandrel rod of chromium plating and chromium plating swing ball because of with copper pipe; Aluminum pipe endoporus plucking or coating scaling and influence the quality of equipment bend pipe in the service life of greatly having improved universal mandrel, are about more than 20 times of universal mandrel life-span of transmission service life; Reduce adjusting machine time, improved the crooked quality conformance of bend pipe.
Description of drawings:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the swing arm structural representation of the utility model;
Fig. 3 is the swing circle spherical structure sketch map of the utility model;
Fig. 4 is the swing arm and swing ball assembly structure sketch map of the utility model.
The specific embodiment:
With reference to Fig. 1-Fig. 4, this specific embodiment adopts following technical scheme: it is made up of mandrel rod 1, housing pin 2, spring 3, pin 4, swing ball 5, swing arm 6; Be respectively arranged with housing pin 2, spring 3 and pin 4 in the mandrel rod 1 from left to right, the right side of pin 4 is provided with swing arm 6, and an end of swing arm 6 is connected with mandrel rod 1 outside swing ball 5.
Described swing ball 5 adopts Hardmetal materials to process for georama designs, and has high rigidity, the effect of high-wearing feature.
The sphere diameter of described swing ball 5 is S ￠ 3-S ￠ 30.
Stick together through gluing between described swing arm 6 and the swing ball 5.
This specific embodiment has greatly improved the wearability of the hardness on universal mandrel groundwork surface; Avoided universal mandrel rod of chromium plating and chromium plating swing ball because of with copper pipe; Aluminum pipe endoporus plucking or coating scaling and influence the quality of equipment bend pipe in the service life of greatly having improved universal mandrel, are about more than 20 times of universal mandrel life-span of transmission service life; Reduce adjusting machine time, improved the crooked quality conformance of bend pipe.
