Description

Technical Field

[0001] The utility model relates to the technical field of rib punching equipment, in particular to rib punching equipment. Background Art

[0002] Projection welding is a high-efficiency welding method that can perform multiple-point welding at the same time. It can be used to replace arc welding, brazing and bite welding. This method has a fast processing speed and no other consumption except electricity, which is a great feature. Compared with spot welding, the difference between projection welding and spot welding is that projections are pre-processed on the plate, or the profiles and chamfers on the weldment that can concentrate the current are used as the mutual contact parts during welding. During welding, the contact of the projections increases the pressure and current density per unit area, which is conducive to breaking the oxide film on the surface of the plate, concentrating the heat, reducing the shunt, and reducing the center distance of the spot welding. Multiple projection welding can be performed at one time, which improves productivity and reduces the warping deformation of the joint. The convex rib welding gun is designed to solve the additional process of convex rib punching in projection welding.

[0003] In the existing process, a convex shape must be formed during the stamping (punching, drawing or forming) process of the plate to enable projection welding. This process requires a complete planning in the early stage to design the parts into the required boss shape, and the initial investment is large. Moreover, once the boss position and shape are confirmed, they cannot be changed, and the welding points cannot be changed flexibly. For this reason, a convex rib punching equipment is proposed.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a convex rib punching equipment, which has the following beneficial effects:

[0018] 1. The main function of the utility model is to punch out bosses corresponding to the positions of welding points on the plates to be welded in advance. This embossing system uses easy-to-control pneumatic control technology to indirectly control a complex hydraulic output mechanism, so that the mechanism can output a greater driving force than a pure pneumatic mechanism. The equipment is lightweight and modular in design structure, which is convenient for later maintenance and flexible in action. Different pressures and punch dies are selected to meet the embossing needs of various plate thicknesses. The welds embossed by this equipment require less pressure from the resistance welding tongs, which has a certain preventive effect on the deformation of the plates. In addition, the electrode heads used by the resistance welding tongs during embossing can all use large-area flat-head electrodes. Due to the increase in the contact area of ​​the electrode, this not only greatly increases the service life of the electrode, but also keeps the surface of the welded plate smooth and beautiful without producing weld marks. When the embossing equipment is used to emboss the plate, the equipment can be fixed to the plate and moved, or the plate can be fixed to the plate and the equipment can be moved.

[0031] See also Figure 1 , Figure 2 and Figure 3 The front end of the machine side shell is provided with a first sensing block 25, a second sensing block 26, a fixing plate 24 and a balancing cylinder 23 in sequence from top to bottom. The first sensing block 25 and the second sensing block 26 are fixed to the machine side shell through a first sensing bracket 19 and a second sensing bracket 27.

[0033] This solution: When the controller of this embossing system receives a specific ready signal, the controller first starts the fast stroke cylinder solenoid valve to control the thrust shaft to pre-tighten the embossing plate in a low-pressure pneumatic force mode. The output force can be adjusted by the total pressure regulating valve. At the same time, the pneumatic valve of the balancing cylinder 23 is controlled to make the sliding mechanism of the dynamic and static embossing heads reach a gravity balance state, so that the embossing heads on the dynamic and static sides can not only clamp the plate, but also prevent the plate from deforming. When the dynamic and static side embossing heads and the plate are pre-tightened in place, and the position measurement sensors on both sides of the dynamic and static sides detect the signal, the controller can start the boost output stroke cylinder solenoid valve to make the thrust shaft output a greater driving force in a hydraulic boosting mode, thereby completing the embossing process of the plate. When the embossing boost clamping time of the plate reaches the preset time, the controller reversely controls the fast stroke cylinder solenoid valve and the boost output stroke cylinder solenoid valve, and the thrust shaft returns to the initial standby state in a fast manner. And the balancing cylinder 23 will also lose the balancing effect due to the logical reverse action of the pneumatic valve, and the static side punching head will slide downward and open, separating from the plate, so as to move to the next punching position for punching operation.
