Abstract

The invention provides a C-type frame roll changing device of a cross roll straightener. The C-type frame roll changing device comprises a hoisting frame and an L-shaped connecting frame. The L-shaped connecting frame is connected with the hoisting frame through a first pin and a second pin. The hoisting frame comprises a straight portion at the top and a vertical portion connected with the straight portion through an arc portion. A first hoisting component is arranged at the top of the straight portion, and a second hoisting component is arranged in the middle of the arc portion. A first through hole and a second through hole are positioned on the same horizontal line and reserved at the bottom of the vertical portion. A third through hole is reserved on the vertical portion above the first through hole. A through hole matched with the first through hole is reserved on an included-angle portion of an L-shaped connecting support, so that the second pin is inserted into the first through hole and the through hole. The weight of roll changing tools is greatly reduced, and the defect that a large roll changing area in front of a straightener is needed during roll changing in the prior art is overcome; and meanwhile, labor and time are saved as compared with those spent in conventional roll changing methods.

Description

Cross-roll straightening machine C type frame-type changing rig

Technical field

The present invention relates to a kind of cross-roll straightening machine C type frame-type changing rig, it is mainly used in cross roll formula straightener, is used for the replacing of WIRE FINISHING LINE zone straightener roller system.

Background technology

The main cross roll formula straightener that uses in existing WIRE FINISHING LINE zone carries out the finishing of bar, improve linearity and the surface quality of bar, and smoothing roll system is topmost wearing detail on the leveller equipment, often cause and to use owing to excessive wear, can only more renew roller, and because the influence of the existing framework of equipment, causing roll change is very much inconvenience.And existing cross roll formula straightener roll change instrument mainly uses old-fashioned counter weight type structure, use crossbeam to add the mode of termination counterweight, need very big roll change zone when causing roll change, and roll change instrument itself also has big weight, with roll change more be that weight is superimposed, driving a vehicle for the lifting that some users are early stage, also is an acid test on the lifting ability.Roll change instrument novel in the patent is not the counter weight type structure, and own wt is light, can effectively improve the efficient of roll change and reduce the difficulty of roll change.

Summary of the invention

The purpose of this invention is to provide a kind of cross-roll straightening machine C type frame-type changing rig, the difficulty when it can reduce the straightener roll change and raising roll change efficient.

For reaching above-mentioned purpose, the invention provides a kind of cross-roll straightening machine C type frame-type changing rig, comprise lifting frame and the L shaped link that connects by first bearing pin and second bearing pin, this lifting frame is by the flat part at top, the vertical portion that is connected with this flat part by curved portions constitutes, the top of flat part is provided with first lifting part, the middle part of curved portions is provided with second lifting part, the bottom of vertical portion is provided with and is in the perforation of first on the same horizontal line and second perforation, vertical portion directly over this first perforation is provided with the 3rd perforation, the angle portion place of L shaped link arranges the perforation that cooperates with described first perforation, so that described second bearing pin inserts in this first perforation and the perforation.

The inner surface of the vertical portion of above-mentioned L shaped link is the inclined-plane that broadens gradually to angle portion from the end, and the width of this end is little or equal distance between the cylindrical of the cylindrical of described first perforation and second perforation.

The bottom arranged outside of above-mentioned vertical portion has a protuberance, and described second perforation is arranged on this protuberance.

Above-mentioned first lifting part is lifting bolt.

Above-mentioned second lifting part is one to be arranged on the lifting hole(eyelet) in the right angle portion in the middle part outside of curved portions.

The horizontal part of above-mentioned L shaped link is provided with screw.

Characteristics of the present invention are: reduce roll change instrument weight significantly, need the shortcoming in the preceding roll change zone of big machine in the time of can improving straightener roll change in the past in addition, roller replacing mode saves manpower and time more than before simultaneously.

The specific embodiment

Cross-roll straightening machine C type frame-type changing rig comprises lifting frame shown in Figure 11 and L shaped link 4 shown in Figure 2.

High-visible by Fig. 1, lifting frame 1 is by the flat part 5 at top, constitute with the vertical portion 7 that this flat part 5 is connected by curved portions 6, the top of flat part 5 is provided with first lifting part 8, is not difficult to find out, first lifting part 8 that provides in the present embodiment is lifting bolts.And the middle part of curved portions 6 is provided with second lifting part 9, is not difficult to find out, second lifting part 9 that provides in the present embodiment is one to be arranged on the lifting hole(eyelet) 18 in the right angle portion 17 in the middle part outside of curved portions 6.

The bottom of vertical portion 7 is provided with and is in the perforation of first on the same horizontal line 10 and second perforation 11, and the vertical portion 7 directly over this first perforation 10 is provided with the 3rd perforation 12.The bottom arranged outside of vertical portion 7 has a protuberance 16, the second perforation 11 to be arranged on this protuberance 16.

As seen from Figure 2, angle portion 13 places of L shaped link 4 arrange and first perforation, 10 perforation that cooperate 20, so that second bearing pin 3 inserts in this first perforation 10 and the perforation 20.

Also can be found out by Fig. 1, be provided with first bearing pin 2 in the 3rd perforation 12.

Can be found out also that by Fig. 2 the inner surface of the vertical portion 14 of L shaped link 4 21 is 15 inclined-planes that broaden gradually to angle portion 13 from the end, the width of this end 15 is little or equal distance between the cylindrical of the cylindrical of first perforation 10 and second perforation 11.The horizontal part 19 of L shaped link 4 is provided with screw 22.

Fig. 3 is that smoothing roll is schematic diagram under changing, detailed process is: the little hook of driving a vehicle is lifting hole(eyelet) 18 by hanging up second lifting part 9, roll change instrument (being cross-roll straightening machine C type frame-type changing rig) is steadily mentioned, mobile road location, it is that 23 handle meets the place that L type link 4 is stretched into smoothing roll to be changed, find accurately connecing the position, be 23 to be fixed as one by bolt 24 with L type link 4 and smoothing roll, it is the lifting bolt 1 shown in Fig. 3 that the big hook of then will driving a vehicle is gone into first lifting part 8, and unclamp the little hook of locating of second lifting part, 9 lifting hole(eyelet)s 18, slowly the lifting ride height and according to around roller be that roll change instrument angle is adjusted in the position, realize taking out smoothly of smoothing roll system down.

As seen from Figure 3, pass first perforation 10 and perforation 20 realizes the lower end of L type links 4 and connecting of lifting frame 1 by second bearing pin 3, and the end 15 of the vertical portion 14 of L type link 4 is inserted into the 3rd and bores a hole that 12 first bearing pin 2 blocks and end 15 places the outside of this first bearing pin 2.

Fig. 4 is that to replace with smoothing roll be schematic diagram, detailed process is 23 identical with changing down smoothing roll, and different is places the second bearing pin 3(, second bearing pin 3 to insert second perforation 11 end 15 of L type link 4) the inboard namely place between first perforation, 10 and second perforation 11.

More than exemplifying only is to illustrate of the present invention, does not constitute the restriction to protection scope of the present invention, and the every and same or analogous design of the present invention all belongs within protection scope of the present invention.
