Description

Hydro piercing equipment
Technical field
The utility model relates to manufactruing equipment of automobile, relates in particular to a kind of hydro piercing equipment, and it can locate based on soldering cramping apparatus the technique of punching.
Background technology
The development of automobile industry is maked rapid progress, the competition in market also becomes a flash point increasingly, each automobile main frame maker also more and more payes attention to for quality, the production efficiency of self product, from punching press, welding, application again to general assembly, can this series of production link better be connected, and this is the urgent problems of considering of a lot of automobile main frame maker.The most obvious problem is that assembly shop is in order to improve assembly quality and efficiency, the workshop that just requires to be welded provides the car body welding assembly that precision is higher, but because there is inevitably distortion in welding, especially the deflection of arc-welding is difficult to control, after making the work of welding assembly, easy assembly quality and efficiency to car body exerts an influence, this has just produced implacable contradiction, if the pilot hole that assembly shop can be had relatively high expectations is realized with other technique again, just can be solved well this contradiction after welding completes.And for the processing of pilot hole, mainly with artificial boring, be main, working (machining) efficiency is lower, and the quality of processing is unstable, formed precision is not very good, and existing hole punched device has been difficult to the punch work of small space because volume is larger, especially the subregion of car body is difficult to realize punching.
Therefore, necessaryly provide a kind of new hydro piercing equipment to solve above-mentioned technical problem.
Summary of the invention
The technical problem that the utility model solves is to provide a kind of hydro piercing equipment, and it can improve crudy and the precision of punching, enhances productivity.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hydro piercing equipment, comprise workbench, be positioned at workbench top platen, be installed on guide rail on described platen, be positioned at described workbench two ends hydraulic power unit, connect the punching assembly of described hydraulic power unit and the positioning component that workpiece is positioned; Described hydraulic power unit is connected with described punching assembly by connecting rod; Described punching assembly comprises a stamping knife, is sheathed on the protective sleeve shielded on described stamping knife and the die socket be oppositely arranged with described stamping knife.
As the further improvement of the technical program, described hydro piercing equipment also comprises a garbage collection box and is positioned at the blanking pipeline of described garbage collection box top.
As the further improvement of the technical program, described guide rail is fixed in the both sides of described platen, and coordinates with described punching assembly.
Compared with prior art, the utility model hydro piercing equipment can be after car body have welded, take hydraulic pressure as power, general assembly is needed to the hole punch forming that precision is higher, because this step process is after welding completes, therefore the impact of just having avoided welding deformation to cause, and practice shows, and the machining accuracy of hydro piercing equipment of the present utility model and crudy are all very stable.
The accompanying drawing explanation
The structural representation that Fig. 1 is hydro piercing equipment described in the utility model.
The specific embodiment
Refer to shown in Fig. 1, the utility model provides a kind of hydro piercing equipment, comprise workbench 10, be positioned at workbench top platen 20, be installed on guide rail 30 on described platen, be positioned at described workbench two ends hydraulic power unit 40, connect the punching assembly 50 of described hydraulic power unit and the positioning component 60 that workpiece is positioned.
Described workbench 10 is the lengthwise type, and the bottom of workbench 10 realizes that by screw position fixes.Described platen 20 is positioned at the surface of described workbench 10, for placing described guide rail 30 and punching assembly 50, to realize the punching operation.Described guide rail 30 is extending longitudinally along workbench 10, and is fixed in the both sides of described platen 20, for accepting described punching assembly 50, and can take exercises for punching assembly 50 direction along ng a paths, the punching operation of realization to car body, and described guide rail 30 is line slideway 30, can guarantee the reliability of punching.
Described hydraulic power unit 40 is positioned at the two ends of described punching assembly 50, and by connecting rod 41, the power in hydraulic power unit 40 is transferred to punching assembly 50, and in the utility model preferred forms, described hydraulic power unit 40 comprises an oil cylinder 42.Described punching assembly 50 is positioned at the top of described workbench 10, and is positioned at the centre of described hydraulic power unit 40.Described punching assembly 50 comprises a stamping knife (not shown) that acts on car body, be sheathed on the protective sleeve 51 that shields on described stamping knife and one and the die socket 52 that is oppositely arranged of described stamping knife; Described stamping knife is the spill stamping knife and is positioned at described protective sleeve 51 inboards, and it uses mould steel is material, through heat treatment, durable in use, and the matrix design can increase cutting power, reduces the noise in punch process; Described die socket 52 is also used mould steel for material, through heat treatment, durable in use, and changes conveniently.Described positioning component 60 utilizes pneumatic control effectively locate and clamp bodywork assembly, guaranteed job stability and the product quality of punching assembly 50, and described hydraulic power unit 40 provides indispensable power for punching assembly 50.
In addition, the utility model hydro piercing equipment also comprises a garbage collection box 70 and is positioned at the blanking pipeline 80 of described garbage collection box top, the waste material that described garbage collection box 70 produces for collecting punching, the waste material produced in punch process finally falls in described garbage collection box 70 via described blanking pipeline 80, make more environmental protection of production process, cleaning equipment is more convenient.
The operation principle of the utility model hydro piercing equipment is: when oil cylinder 42 action, described stamping knife is pushed die socket 52 under the constraint of high-precision line slideway 30, when stamping knife, die socket and after the workpiece three contacts, produce the punching action, waste material is fallen garbage collection box 70.
In sum, hydro piercing equipment described in the utility model, it can take hydraulic pressure as power after car body has welded, and general assembly is needed to the hole punch forming that precision is higher.Because this step process is after welding completes, therefore the impact of just having avoided welding deformation to cause, and employing hydraulic pressure is power, compared to artificial boring, more efficient, stable and moulding is attractive in appearance, and with hydraulic system, drive oil cylinder to realize punch work, thin cylinder has been used in the part position, has greatly reduced to take up room.In addition, hydro piercing equipment described in the utility model also can be made switchable form, to adapt to the Flexible Production of multi-vehicle-type switching, guarantees the vehicle body precision, has improved labor productivity.
The above; it is only most preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any those of ordinary skill in the art; do not breaking away from technical solutions of the utility model scope situation; utilize the method content of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, all belong to the scope of claims protection.
