Abstract
The utility model discloses a novel type spring-return type hydraulic steel plate shearer. The novel type spring-return type hydraulic steel plate shearer comprises guideposts and an upper blade, wherein the number of the guideposts is two and the guideposts are fixed on a rack, the guideposts are slidingly matched with the upper blade, shaft sleeves are arranged on the left side and the right side of the upper blade, the shaft sleeves are matched with the guideposts; the novel type spring-return type hydraulic steel plate shearer further comprises two resetting springs which are sleeved on the two guideposts between the shaft sleeves and the rack and sldingly matched with the guideposts, a clamping hole is formed in the position of connection between the rack and the guideposts, the lower ends of the resetting springs are clamped with the clamping hole, a footstep hole is inside the shaft sleeve and sleeved on the guideposts, a little diameter hole is formed on the upper portion inside the shaft sleeves, a bore diameter corresponds to the diameters of the guideposts, a big diameter hole is formed on the lower portion inside the shaft sleeves, the bore diameter corresponds to the external diameters of the resetting springs, and the upper ends of the resetting springs are clamped with the big diameter hole of the shaft sleeves. The novel type spring-return type hydraulic steel plate shearer arranges the resetting springs on the guideposts by changing the position of the resetting springs, thereby avoiding the local friction between the sleeve and the guidepost in a long period when the steel plate shearer is used, and effectively prolonging service life of the steel plate shearer.
Description
Technical field
The utility model relates to clipper device.
Background technology
The rear portion that present spring return type hydraulic plate shears generally is arranged on back-moving spring hydraulic plate shears is fixedly connected with cutter, promotes cutter by back-moving spring and resets.This design is so that when spring promotion cutter resets, so that whole cutter is subject to the forward component of rotation, so that the local stressed increase of contact position in the position that blade cooperates with lead and then so that local friction's power increase, operate so that concentrated wear is serious for a long time according to this hydraulic plate shears, shortened the service life of hydraulic plate shears.
The utility model content
The utility model provides a kind of Novel spring reset hydraulic plate shears, has avoided in use long local friction between sleeve and the lead of plate shearing machine, has effectively prolonged the service life of plate shearing machine.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of Novel spring reset hydraulic plate shears comprises lead and cutter, and lead has two lower ends to be fixed on the frame, and the lead of the cutter left and right sides is slidingly matched,
Two ends, the described cutter left and right sides are equipped with axle sleeve, and axle sleeve and lead are slidingly matched,
Also comprise back-moving spring,
Described back-moving spring has two, is enclosed within respectively on two leads, is arranged between described axle sleeve and the described frame, is slidingly matched with lead.
The position that is connected with lead in described frame is provided with Ka Dong, and the end, lower end of back-moving spring is filled in the card hole and engaged with Ka Dong.
Described axle sleeve inside is stepped hole, is enclosed within on the lead, and the top in the described axle sleeve is small diameter bore, the aperture is corresponding with the lead diameter, bottom in the described axle sleeve is large diameter hole, and the aperture is corresponding with the external diameter of back-moving spring, and the back-moving spring upper end engages with the large diameter hole of axle sleeve.
Further, the large diameter hole of described axle sleeve is provided with the screw thread of certain-length, the back-moving spring that the spinning reduction spring can make and threaded engagement.
The utility model is about to back-moving spring and is installed on the lead by to the change of back-moving spring position, has avoided in use long local friction between sleeve and the lead of plate shearing machine, has effectively prolonged the service life of plate shearing machine.
Description of drawings
The below is described in further detail the utility model with embodiment with reference to the accompanying drawings.
Fig. 1 is the structural representation of the described Novel spring reset hydraulic plate shears of the utility model embodiment.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Shown in Fig. 1-2, the described Novel spring reset hydraulic plate shears of the utility model embodiment, comprise lead 1 and cutter 2, lead 1 has two lower ends to be fixed on the frame 3, the lead 1 of cutter 2 left and right sides is slidingly matched, two ends, described cutter 2 left and right sides are equipped with axle sleeve 21, and axle sleeve 21 is slidingly matched with lead 1
Also comprise back-moving spring 4,
Back-moving spring 4 has two, is enclosed within respectively on two leads 1, is arranged between axle sleeve 21 and the frame 3, is slidingly matched with lead 1.
The position that frame 3 is connected with lead 1 is provided with card hole 31, and the end, lower end of back-moving spring 4 is filled in the card hole 31 and engaged with card hole 31.
Axle sleeve 21 inside are stepped hole, are enclosed within on the lead 1, and the top in the axle sleeve 21 is small diameter bore, the aperture is corresponding with lead 1 diameter, bottom in the axle sleeve 21 is large diameter hole, and the aperture is corresponding with the external diameter of back-moving spring 4, and back-moving spring 4 upper ends engage with the large diameter hole of axle sleeve 21.
The large diameter hole of axle sleeve 21 is provided with the screw thread of certain-length, back-moving spring 4 and threaded engagement that spinning reduction spring 4 can make.
The utility model in use, hydraulic jack drive cutter 2 moves downward at lead 1 to be sheared, and while cutter two ends axle sleeve 21 compression reseting springs 4 are after shearing finishes, back-moving spring 4 recovers shape, and then drive cutter 2 is returned to upper position.
The utility model is about to back-moving spring and is installed on the lead by to the change of back-moving spring position, has avoided in use long local friction between sleeve and the lead of plate shearing machine, has effectively prolonged the service life of plate shearing machine.
