Description
Technical Field
The utility model relates to a hydraulic support connecting rod, specific theory has related to a hydraulic support connecting rod apron.
Background
The hydraulic support connecting rod is an important part on a hydraulic support and is used for being connected between a shield beam and a base, and the requirements on yield strength, rigidity and impact resistance of the connecting rod are high due to the fact that complex external forces such as large tension and compression, large torque and the like need to be borne in the work process. The connecting rod generally comprises main muscle subassembly, apron and gusset, and the groove of apron length direction edge design has formed the unilateral groove weld with the plane cooperation of main muscle subassembly, and the groove of current connecting rod apron design is great, causes the welding volume too big, and welding deformation is serious, can influence the axiality and the overall dimension precision of connecting rod hinge hole. In addition, current connecting rod apron is the right angle transition in the poor step department of width, causes the welding seam at apron groove step department to need alternate the rifle appearance by a wide margin in welding process, is unfavorable for robot automatic weld to the right angle welding seam of step department causes very big stress concentration easily, influences the whole atress!of connecting rod apron welding seam!
The hydraulic support is a small-batch customized product, the length, the width and other dimensions of the connecting rod cover plate of the hydraulic support are not fixed, and almost every batch of the connecting rod cover plate can be changed. The bending radius and the bending angle of the connecting rod cover plate of the hydraulic support are not fixed, so that the frequent parameter adjustment of bending equipment is caused when the connecting rod cover plate is processed, the resilience of a bent steel plate is difficult to control, and the bending precision is poor.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The utility model aims at the not enough of prior art to a hydraulic support connecting rod apron that welding volume is little, the product precision is high, the robot of being convenient for welds, self stress is little is provided.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a hydraulic support connecting rod apron, is in including wide slab section and setting the narrow slab section at the horizontal both ends of wide slab section, narrow slab section outer end is to the positive crooked setting of apron, the vertical both sides limit back of wide slab section with the vertical both sides limit back of narrow slab section all is provided with the groove, hydraulic support connecting rod apron is symmetrical structure for self horizontal center pin and vertical center pin, the horizontal both ends of wide slab section respectively through a transition hypotenuse with the narrow slab section is connected, the angle of groove is 30-40.
Based on the above, the thickness of the truncated edge of the groove is 1-5 mm.
Based on the above, the inclination angle of the transition bevel edge is 45 °.
Based on the above, the bending angle of the outer end of the narrow plate section is 120 degrees, and the radius of the bending arc is 60 mm.
Compared with the prior art, the utility model have substantive characteristics and progress, specific theory, the utility model discloses will groove angle sets up to 30-40, compares with traditional 40-50 groove, and the welding volume reduces, and welding efficiency improves more than 15%, and edge thermal deformation alleviates to improve the product precision, become traditional right angle step and do transition hypotenuse makes things convenient for the robot to weld in succession, and has reduced stress concentration, and it has that the welding volume is little, the product precision is high, the robot of being convenient for welds, advantage that self stress is little.
Further, the bending angle and the bending arc radius of the outer end of the narrow plate section are cured, and all the curing parameters of different types of cover plates can be cured in a workshop, so that the production efficiency and the manufacturing precision of the bending process are greatly improved.

Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
As shown in fig. 1-3, a hydraulic support connecting rod cover plate, the hydraulic support connecting rod cover plate is a symmetrical structure relative to its own horizontal central axis and longitudinal central axis, and includes a wide plate section 1 and narrow plate sections 2 disposed at the horizontal two ends of the wide plate section 1, the outer ends of the narrow plate sections 2 are arranged in a bending manner towards the front surface of the cover plate, the bending angle is 120 °, and the radius of the bending arc is 60 mm.
The longitudinal two side backs of the wide plate section 1 and the longitudinal two side backs of the narrow plate section 2 are both provided with grooves 4, the two transverse ends of the wide plate section 1 are respectively connected with the narrow plate section 2 through a transition bevel edge 3, the inclination angle of the transition bevel edge is 45 degrees, the angle of the groove 4 is 30-40 degrees, and the thickness of the truncated edge of the groove is 1-5 mm.
The working principle is as follows:
the angle of the groove 4 is set to be 30-40 degrees, the groove is narrower in welding line after being spliced with a main rib assembly, welding amount is greatly reduced, welding efficiency can be improved by more than 15%, thermal deformation of the edge of the cover plate is reduced, product precision is improved, the transition bevel edge 3 is inclined by 45 degrees, a robot can conveniently weld continuously, stress concentration at the position can be greatly reduced in a Canada mode, product performance is improved, the bending angle and the bending arc radius of the outer end of the narrow plate section 2 are solidified, the workshop can solidify parameters for the cover plates of different types, and production efficiency and manufacturing precision of a bending process are greatly improved.
