Abstract
The utility model relates to a laser auxiliary heating device for self-piercing riveting. The laser auxiliary heating device for the self-piercing riveting comprises a concave die, a laser heater, a first pin shaft, a second pin shaft, a punch, a connecting rod and a blank holder. A lower sheet and an upper sheet are arranged in the concave die and tightly pressed through the blank holder. The laser heater is located in an extensional sliding rail which is arranged on one side of the blank holder. The laser heater is connected with the connecting rod through the first pin shaft, the connecting rod can rotate around the first pin shaft, the other end of the connecting rod is connected with the punch through the second pin shaft, and the connecting rod can rotate around the second pin shaft. The punch is located inside the blank holder and can move up and down along the blank holder, and the connecting rod drives the laser heater to transversely slide in the extensional sliding rail of the blank holder. An opening groove is formed above the extensional sliding groove on one side of the blank holder, and the connecting rod is located in the opening groove. The laser auxiliary heating device for the self-piercing riveting can rapidly conduct the self-piercing riveting after laser heating for sheets is conducted.
Description
Technical field:
The utility model relates to a kind of laser auxiliary heating device, relates in particular to a kind of laser auxiliary heating device for self-piercing riveting.
Background technology:
Self-punching riveting technology is a kind of new light sheet material interconnection technique of development in recent years, is specially adapted to the hard-to-weld sheet materials such as light-duty alloy, composite, is the optimal substitute technology of traditional electrical welding technology.In breadth light alloy plate self-piercing riveting process, jointly carry out plastic deformation by rivet and sheet material, form the connection that power is connected with shape.But the defective such as very easily crack when carrying out plastic deformation at normal temperatures such as light-duty alloys such as magnesium alloys, must be heated to certain temperature and just can carry out self-piercing riveting.In self-piercing riveting processing, for guaranteeing the normal operation of production line, usually require each self-pierce riveting contact within the several seconds, to finish, and that the methods such as electrical heating that at present field of industrial production is commonly used are difficult within the several seconds the light-duty sheet alloys such as magnesium alloy are heated to is temperature required, this so that the light-duty sheet alloy self-punching riveting technology such as magnesium alloy be greatly limited in the extensive use of each field of industrial production.
Summary of the invention:
The utility model is the restriction of using in order to solve the sheet material self-punching riveting technologies such as magnesium alloy in the above-mentioned technical background, and a kind of laser auxiliary heating device for self-piercing riveting is provided, to solve carrying out rapidly the problem of self-piercing riveting after the plate Fast Heating.The utility model is achieved by the following technical solutions:
A kind of laser auxiliary heating device context summary for self-piercing riveting of the utility model: whole device is by die, laser heater, and the first bearing pin, the second bearing pin, drift, connecting rod, blank holder forms, and upper plate and lower plate place on the die, are compressed by blank holder.One side of blank holder has outward extending square slide rail, and laser heater is positioned in the extension slide rail of blank holder.Laser heater links to each other with connecting rod by the first bearing pin, and connecting rod can rotate around the first bearing pin, and the other end of connecting rod links to each other with drift by the second bearing pin, and connecting rod can rotate around the second bearing pin simultaneously.Drift is positioned at blank holder inside, can move up and down along blank holder, and driving laser heater by connecting rod simultaneously can laterally slide in the extension slide rail of blank holder.There is open slot the one side extension slide rail top of blank holder, and connecting rod is positioned at open slot.When drift was positioned at stamping position, connecting rod was upper along concordant with laser heater.
The beneficial effects of the utility model are: the utility model can be finished the self-piercing riveting of riveting point rapidly, by laser heater sheet material is heated, when temperature reaches preset value, drift is punching press downwards just, laser heater moves in the extension slide rail of blank holder simultaneously, drift is finished the backward upper motion of self-piercing riveting, and laser heater moves to the center of blank holder simultaneously, prepares next riveting point is heated.The utility model is improved the efficient of the self-piercing riveting that needs heating sheet material.

Among the figure, 1. die 2. descends plate, 3. goes up plate, 4. laser heater, 5. the first bearing pin, 6. the second bearing pin, 7. drift, 8. connecting rod, 9. blank holder.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 2, the utility model is by die 1, laser heater 4, the first bearing pins 5, the second bearing pins 6, and drift 7, connecting rod 8, blank holder 9 forms.Before the self-piercing riveting, plate is placed on the die 1, compress by blank holder 9.Laser heater 4 is positioned at the center of blank holder, plate is heated, when the plate temperature reaches preset value, drift 7 downward punching presses, simultaneously by connecting rod 8 drive laser heater 4 along slide rail to blank holder 9 outer side shifting.When drift 7 is positioned at stamping position, connecting rod 8 move to laser heater 4 on along flush position, it is inner that laser heater 4 moves to the extension slide rail of blank holder 9 fully.After self-piercing riveting is finished, drift 7 moves upward, and drives laser heater 4 by connecting rod 8 simultaneously and moves to blank holder 9 centers, when drift 7 moves to initial position, laser heater 4 just is in the center position of blank holder 9, prepares next riveting point is heated.
