Description
Technical field
The utility model relates to automobile stamping machine tool technology field, is specially a kind of buffer unit for body of a motor car stamping machine.
Background technology
In the punching production of body of a motor car stamping parts, blank operation is sheet material fracture moment hydraulic press Condition of Sudden Unloading, mistake lotus, workpiece load is suddenly disappeared, in-oil cylinder liquid compression energy and fuselage elastic deformation energy sharply discharge, cause sheet material out of control suddenly at fracture moment drift, with great speed undershoot, huge impact is produced to cushion dashpot, stamping machine not only can produce huge strong spring, shock and vibration, very large noise, and stamping machine and mould are all caused damage, have a strong impact on precision and the service life of stamping machine.
Utility model content
Problem to be solved in the utility model is, for when in the automobile stamping lathe use of prior art, load disappears, drift causes enormous impact to mould and lathe, produce strenuous vibration and larger noise, mould and lathe are caused damage, have a strong impact on the defect in mould and machine tool accuracy and service life, a kind of buffer unit for body of a motor car stamping machine is provided.
The utility model solves the problems of the technologies described above adopted technical scheme, build a kind of buffer unit for body of a motor car stamping machine, above-mentioned stamping machine comprises workbench, be located at the punch assembly directly over workbench, also buffer unit is provided with between said modules and above-mentioned workbench, above-mentioned buffer unit comprises the multiple bumper posts be located at bottom said modules, also comprise and being located on above-mentioned workbench and the cushion dashpot corresponding with bumper post position and number, buffer bar top in above-mentioned cushion dashpot has been threaded connection buffering steel pad, above-mentioned buffering steel pad is cylindrical, on it, top is provided with cylindrical boss, it is gone to the bottom and is provided with screwed hole.
Further, in buffer unit provided by the utility model, the external diameter of above-mentioned buffering steel pad is less than the external diameter of above-mentioned buffer bar.
Further, in buffer unit provided by the utility model, the height of above-mentioned boss is that 0.2-0.5 doubly cushions steel mat thickness.
Further, in buffer unit provided by the utility model, the external diameter of above-mentioned boss is the external diameter that 0.1-0.3 doubly cushions steel pad.
Further, in buffer unit provided by the utility model, the material of above-mentioned buffering steel pad is 45# steel.
Further, in buffer unit provided by the utility model, the number of above-mentioned buffering steel pad is more than or equal to 8.
Compared with prior art; a kind of buffer unit for body of a motor car stamping machine provided by the utility model; can in punching press during load disappearance; slow down drift to impact mould and lathe; greatly reduce the generation of vibrations and noise; protection mould and lathe do not suffer damage, and ensure mould and machine tool accuracy and increase the service life.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the schematic diagram cushioning steel pad in Fig. 1.
Detailed description of the invention
Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described further.
embodiment 1
By reference to the accompanying drawings, the present embodiment is described in detail as follows structure of the present utility model.
Refer to Fig. 1 and Fig. 2, a kind of buffer unit for body of a motor car stamping machine that the utility model provides, wherein stamping machine comprises workbench 2, be located at the punch assembly 1 directly over workbench 2, it is characterized in that, also buffer unit is provided with between punch assembly 1 and workbench, buffer unit comprises the multiple bumper posts 301 being located at component bottom, also comprise and being located on workbench 2 and the cushion dashpot 304 corresponding with bumper post 301 position and number, buffer bar 303 top in cushion dashpot 304 has been threaded connection buffering steel pad 302, the number of buffering steel pad is more than or equal to 8, the material of buffering steel pad is 45# steel, buffering steel pad 302 is cylindrical, on it, top is provided with cylindrical boss, it is gone to the bottom and is provided with screwed hole, the external diameter of buffering steel pad is less than the external diameter of buffer bar, the height of boss is that 0.2-0.5 doubly cushions steel mat thickness, the external diameter of boss is the external diameter that 0.1-0.3 doubly cushions steel pad 302.
The setting of buffering steel pad 302, on the one hand, can conveniently mount and dismount, available protecting cushion dashpot 304, prevent bumper post 301 direct collision buffer bar 303, prevent buffer bar from occurring because of multiple impacts damageeing causing deterioration in accuracy, need whole cushion dashpot 304 to disassemble maintenance, effectively extend the life-span of buffer unit, also namely protect the life-span of lathe; The bottom of buffering steel pad 302 is connected with buffer bar 303 by screw thread on the other hand, by the punching stroke between screw thread next fine adjustment buffering steel pad 302 and bumper post 301 (in punching course, be subject to the restriction of equipment and cushion dashpot, often can not adjust to theoretical best stroke), can be accurate punching course and theoretical punching stroke be matched, ensures the precision of punching press; Finally, the design of top boss, can play orientation, further ensure the accuracy of punching press between bumper post 301 and buffer bar 303, prevents from damaging grinding tool and stamping machine, and decreases the generation of vibration and noise.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection domain of the present utility model should define with the utility model claim is as the criterion.
