Description

Drop handle simmering and bending device

Technical field

The utility model relates to a kind of oil-well rig tap, drop handle simmering and bending device is driven on the top.

Background technology

At present, manual open die forging forging drop handle is adopted in the drop handle simmering and bending, the main forging hammer hitting power of using makes its bending, because the cell-type heating means cause and simmer on forging hammer in the system process the inhomogeneities of workpiece heating, the drop handle two ends are asymmetric, bent intermediate part radius of curvature does not wait, and does not reach the technological requirement size, and the apparent size of drop handle is difficult to control, inherent quality also is difficult for guaranteeing, brings many influences to following process.Every product needed heating 6～7 fire just can be finished for 2～3 classes in the actual production, have very big potential safety hazard in the production process simultaneously, and problem such as production efficiency is low, energy consumption big, operator's working strength is big.

Summary of the invention

The technical problem that the utility model solves: design a kind of drop handle simmering and bending device, can not only make large-scale drop handle reach a simmering and bending moulding, the more important thing is and improved drop handle simmering and bending quality and production efficiency greatly, reduce labour intensity and production cost, overcome problems such as existing production efficiency is low, quality is unstable, labour intensity is big, cost height.

The technical solution adopted in the utility model: a kind of drop handle simmering and bending device, on the pedestal 1 oil cylinder is installed, slide block I one end that is provided with in the chute I is connected with oil cylinder, and other end middle part is connected with punch, and the bottom is connected with the guider that two ends are fixed on the pedestal; Two chute II and chute I symmetry in vertical direction are installed on the pedestal, and the slide block II that is provided with in the chute II is connected with the leading screw adjusting device, and axle is housed in the slide block, and rotatable baffle plate and stiffening device are installed on the axle; Supporting and regulating device is installed in the both sides of pedestal.

Described guider is passed by guide post that the bearing by two ends is fixed on the pedestal behind the hole of slide block I bottom, and slide block I slides on the chute I between two bearings.

Described supporting and regulating device is by forming with the roller of fixedlying connected with screw mandrel with the fixing handle of adjusting nut.

Described stiffening device be positioned at two chute II diaxon the upper end and diaxon coupled together.

The utility model advantage compared with prior art: can make that drop handle once heats, the simmering and bending moulding, effectively improved product simmering and bending quality, one time delivery-check qualified rate reaches more than 99%, and operating efficiency improves more than 6 times, and has reduced working strength of workers and production cost; Adapt to the workpiece of different size, reduced the simmering and bending workload, realized the simmering and bending of large-scale drop handle class A of geometric unitA.

The specific embodiment

Below in conjunction with accompanying

drawing

1,2,3,4,5,6,7 and 8 explanation structure of the present utility model and operation principles.

A kind of drop handle simmering and bending device, oil cylinder 2 is installed on the pedestal 1, slide block I8 one end that is provided with in the chute I3 is connected with oil cylinder 2, other end middle part is connected with punch 9, the bottom is connected with the guider 6 that two ends are fixed on the pedestal 1, guider 6 is passed by guide post 17 that the bearing 16 by two ends is fixed on the pedestal 1 behind the hole of slide block I8 bottom, slide block I8 slides on the chute I3 between two bearings 16, pedestal 1 is equipped with guider 6, because of oil cylinder 2 center lines (being force axis) and slide block I8 center of gravity not on same axis, the oil cylinder piston club head is a ball shape in addition, can produce certain moment during work, guider 6 can effectively prevent to chew chute I3 because of moment makes slide block I8; Two chute II4 and chute I3 symmetry in vertical direction are installed on the pedestal 1, the slide block II10 that is provided with in the chute II4 is connected with leading screw adjusting device 7, axle 11 is housed in the slide block 10, rotatable baffle plate 12 and stiffening device 13 are installed on the axle 11, stiffening device 13 be positioned at two chute II4 diaxon 11 the upper end and diaxon 11 coupled together; Supporting and regulating device 5 is installed in the both sides of pedestal 1, and supporting and regulating device 5 is by forming with the roller 20 of fixedlying connected with screw mandrel 19 with adjusting nut 18 fixing handles 21.

Operation principle: move forward along chute I3 and guider 6 by oil cylinder 2 drive slide block I8, punch 9, promoting workpiece 15 moves forward, utilize the resistance of 12 pairs of workpiece 15 of rotatable baffle plate, it is crooked that work 15 is progressively produced, until reaching technological requirement, according to the bending process size of workpiece, utilize leading screw adjusting device 7 manual adjustments axles 11 centre-to-centre spacing, change the specification of punch 9; Workpiece is placed on the supporting and regulating device 5, and it is consistent with the center line of oil cylinder 2 to regulate the center of workpiece by manual adjustment supporting and regulating device 5 according to the diameter of workpiece, length parameter; Application-oriented device 6 guarantees slide block I8 running orbit, and the direction that is to say active force in the simmering and bending process is all the time on a line; Rotatable baffle plate 12 can realize that workpiece can not be loaded on stiffening device 13 on the axle 11 because of the different problem of the inhomogeneous bending curvature that produces of being heated again, just can realize simmering and bending shaping work of workpiece in the simmering and bending process.
