Abstract
The utility model discloses a back blocking device of a bending machine. The back blocking device comprises a guide rod, a lead screw, a fixing base, a pair of nuts and a spring. The lead screw is arranged on the lower side of the guide rod in parallel, the two ends of the guide rod and the two ends of the lead screw are fixed to bearing plates respectively, and the front end bearing plate is connected with a working table of the bending machine. The guide rod is sleeved with the upper side of the fixing base, the fixing base and the guide rod are connected in a movable mode, the lead screw transversely penetrates through the lower side of the fixing base, and the nuts are respectively screwed onto the lead screw and fixed to an inner hole in the lower side of the fixing base. The lead screw is sleeved with the spring and, the spring is positioned between the two nuts, and the two ends of the spring abut against the two opposite end faces of the nuts respectively. The two nuts are arranged in the inner hole in the lower side of the fixing base, the spring is arranged between the two nuts, when the lead screw stops rotating, the axial clearances between the lead screw and the nuts can be effectively eliminated, back blocking locating accuracy and repeated locating accuracy of the bending machine are guaranteed, bending accuracy of boards is improved, the quality of products is improved, and the rejection rate is reduced.
Description
Technical field
The utility model relates to a kind of bender, and especially a kind of rear material stopping device for bending machine, belongs to panel beating equipment technical field.
Background technology
Rear material stopping device for bending machine is the important process mechanism that bender is located for bending, and its Main Function is the feed length of controlling sheet material to be processed, guarantees that sheet material is in precalculated position bending.Existing rear material stopping device for bending machine comprises guide rod, screw mandrel, nut and holder, and motor drives screw pair to carry out transmission, and under the guide effect of guide rod, nut drives holder to move as reciprocating linear, thereby drives striker plate to move to precalculated position.After the long-term use of rear material stopping device for bending machine, wearing and tearing due to contact-making surface between screw mandrel, nut, cause end play between screw mandrel and nut to strengthen, reduced positioning precision and the repetitive positioning accuracy of rear baffle of bending machine, finally affect the Bending Processing precision of sheet material.
Summary of the invention
Thereby the purpose of this utility model be to provide a kind of simple in structure, can effectively eliminate the rear material stopping device for bending machine that gap between screw mandrel and nut guarantees sheet material machining accuracy.
The utility model is achieved by the following technical programs:
A rear material stopping device for bending machine, comprises guide rod, screw mandrel, holder, a pair of nut and spring, and described screw mandrel is set in parallel in guide rod downside, and guide rod and screw mandrel two ends are separately fixed on support plate, and front end support plate is connected with bending machine workbench.Holder upside is sleeved on guide rod, is connected with guide rod is removable, and holder upper-side hole is equipped with guide rod, and screw mandrel crosses holder downside, and a pair of nut screws on screw mandrel respectively, and is fixed in holder downside endoporus; Described spring housing is contained on screw mandrel, and between a pair of nut, both ends of the spring is resisted against respectively on two opposing end surfaces of a pair of nut.
The utility model is provided with a pair of nut in holder downside endoporus, and between two nuts, spring is set, after screw mandrel stops the rotation, can effectively eliminate the end play between screw mandrel and nut, guarantee positioning precision and the repetitive positioning accuracy of rear baffle of bending machine, improve the bending precision of sheet material, thereby improved product quality, reduced percent defective.
Advantage and disadvantage of the present utility model, the non-limitative illustration by preferred embodiment below is for illustration and explanation, and these embodiment, only provide as an example with reference to accompanying drawing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises guide rod 1, is set in parallel in the screw mandrel 2 of guide rod 1 below, holder 3, a pair of nut and spring 5, guide rod 1 and screw mandrel 2 two ends are separately fixed on support plate 6, guide rod 1 crosses the hole of holder 3 upsides, holder 3 can move forward and backward along guide rod 1, screw mandrel 2 crosses holder 3 downsides, a pair of nut screws respectively on screw mandrel 2, be arranged in holder 3 downside endoporus, the first nut 41 is fixedly connected with holder 3 by junction of the edges of two sheets of paper screw 7, and the second nut 42 is fixedly connected with holder 3 by hold-down nut 8, holding screw 9.Spring 5 is sleeved on screw mandrel 2, and between a pair of nut, spring 5 two ends are resisted against respectively on two opposing end surfaces of nut 42 on left side nut 41 and right side.After screw mandrel 2 stops the rotation, the elastic force of spring 5 promotes respectively the first nut 41 and the second nut 42 moves separately round about, thereby eliminate the first nut 41 or the internal thread of the second nut 42 and the end play between screw mandrel 2 external screw threads, improve positioning precision and the repetitive positioning accuracy of rear baffle of bending machine.
In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
