Abstract
The utility model discloses a device for connecting a jaw and an oil cylinder piston rod of a hydraulic drawing machine. A clamp is pushed by a single oil cylinder, the end of the oil cylinder piston rod penetrates through a connecting sheet, pin holes are formed at two ends of the connecting sheet, and the jaw is connected with the oil cylinder piston rod through a pin. The device is characterized in that the pin holes are fillet rectangular holes. By adoption of the device, radial force generated by the extending unbalance of the jaw is eliminated, the oil cylinder piston rod is prevented from being broken, the cost of spare parts is saved, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of hydraulic drawbench jaw and oil cylinder piston rod connecting device, belongs to mechanical field.
Background technology
The Main Function of hydraulic drawbench is the equipment for the production of metal tube, rod and profile shapes, pulling capacity equipment below 100 tons extensively adopts the work of single oil cylinder pushing clamp at present, in actual drawing process, both sides jaw integrated circuit board tooth can not wear and tear identical fully, if a certain lateral wearing is larger, just may occur in the drawing process skidding between jaw plate and the pipe drawing head, the little side jaw that weares and teares can be followed the pipe drawing head and be stretched out, at this moment cylinder piston rod is subject to radial load, often causes the cylinder piston rod fracture.
Summary of the invention
Often cause the cylinder piston rod breakage problem in order to solve in the work of single clamp oil cylinder, the utility model provides a kind of hydraulic drawbench jaw and oil cylinder piston rod connecting device.
The technical solution adopted in the utility model is: a kind of hydraulic drawbench jaw and oil cylinder piston rod connecting device, clamp adopts single oil cylinder pushing, the oil cylinder piston boom end passes brace, the brace two ends are provided with pin-and-hole, jaw is connected by pin with cylinder piston rod, it is characterized in that: pin-and-hole is the fillet slot.
The hydraulic drawbench jaw that the utility model provides and oil cylinder piston rod connecting device, the jaw engaging lug is prolonged, fixed pin holes changes the fillet slot into by circular hole, eliminate owing to jaw stretches out the radial load that imbalance produces, prevent other oil-break cylinder piston rod, save spare parts cost, improved production efficiency.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 is jaw among the figure, and 2 are the card tooth, and 3 is piston rod, and 4 is oil cylinder, and 5 is pin-and-hole, and 6 is brace.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of hydraulic drawbench jaw and oil cylinder piston rod connecting device, clamp adopts single oil cylinder pushing, brace 6 is passed in cylinder piston rod 3 ends, brace 6 two ends are provided with pin-and-hole 5, and jaw 1 and cylinder piston rod 3 are connected by pin, and it is characterized in that: pin-and-hole 5 is the fillet slot.
Go into operation in rear one month 10 of disconnected clamp oil cylinders of 8 hydraulic drawbench of Taiyuan Iron and Steel Co. stainless steel tube company, after the trial edition design, Duan phenomenon by the end of the clamp cylinder piston rod not occurring at present again, oil cylinder does not take human cost and impact is produced because change, and project implementation effect is remarkable.
