Abstract
The utility model discloses a connecting structure of a press connecting rod and a semicircular tile and belongs to the technical field of press parts. The connecting structure comprises a connecting rod, a plunger, a semi-circular tile and a connecting pin. The connecting rod and the plunger are connected through the connecting pin, the semicircular tile is arranged on the lower portion of the connecting rod integrally, and the connecting pin and the semicircular tile are of a concentric structure. The connecting structure has the advantages of avoiding a phenomenon of loosening and breaking of screws and pins caused by the fact that the semicircular tile is assembled on the connecting rod through a connecting method by using the screws and the pins, reducing external faults, and simultaneously being capable of reducing production cost and shortening a production period.
Description
Technical field
The utility model relates to a kind of press connecting rod semi arch watt syndeton, belongs to forcing press parts technical field.
Background technology
In the forcing press processing industry, traditional connecting rod and semi arch watt syndeton all is to adopt screw and pin connected mode that semi arch watt is assemblied on the connecting rod.Because forcing press in the course of the work; The transmission of connecting rod semi arch watt and the existing pressure of plunger inner hole surface, relative slip is arranged simultaneously again; Semi arch watt is fixed on the screw and the pin of connecting rod, will bears certain shearing force inevitably, after long-time the use; Screw and pin can produce loosening phenomenon of rupture, and external fault is more.Traditional connecting rod and semi arch tile structure; In order to reduce the probability that screw and pin can become flexible fracture; Take on connecting rod semicircle cambered surface, to increase the design of seam; Purpose is to make the semi arch watt shearing of bearing, and directly passes to connecting rod through seam, avoids screw and pin loosening phenomenon of rupture to occur because of bearing shearing force.But the semicircle cambered surface and the seam of this designing requirement semi arch watt and connecting rod must be the zero clearance contact, otherwise screw and pin also will bear certain shearing force.Such syndeton, arc surface and arc size processing to the semicircle cambered surface of connecting rod and seam processing and semi arch watt have all proposed high-precision requirement.In actual production, not only working (machining) efficiency is low, percent defective is high, the manufacturing cycle is difficult to guarantee, increased processing cost, and from fault rate after sale, improvement effect is very limited.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of press connecting rod semi arch watt syndeton, prolongs semi arch watt service life, reduces fault rate, reduces production costs, shortens the production cycle.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of press connecting rod semi arch watt syndeton; Comprise connecting rod, plunger, semi arch watt and connecting pin, connecting rod and plunger link together through connecting pin, and semi arch watt is positioned at the below of connecting rod; As a whole with connecting rod, connecting pin and semi arch watt are concentric structure.
The beneficial effect of the utility model is: avoided through with the connected mode of screw and pin semi arch watt being assemblied in screw and the loosening phenomenon of rupture of pin that produces on the connecting rod; Prolonged semi arch watt service life; Reduced external fault, also can reduce production costs simultaneously, shorten the production cycle.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the side view of the utility model;
Fig. 3 is the partial enlarged drawing of A portion among Fig. 1.
Among the figure: 1, connecting rod, 2, connecting pin, 3, plunger, 4, semi arch watt, 5, connecting rod semicircle cambered surface seam.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, Fig. 2 and shown in Figure 3; This press connecting rod semi arch watt syndeton; Comprise connecting rod 1, plunger 3, semi arch watts 4 and connecting pin 2, connecting rod 1 links together through connecting pin 2 with plunger 3, and semi arch watts 4 is positioned at the below of connecting rod 1; As a whole with connecting rod 1, connecting pin 2 and semi arch watts 4 is concentric structure.Semi arch watt 4 rubbing surfaces rotate around connecting pin 2 centers; Rotating range is in 180 °; The connected mode of connecting rod 1 and semi arch watts 4; By original screw and the pin of passing through with the structure that semi arch watts 4 is fixed on the connecting rod 1, the semicircle cambered surface that changes connecting rod 1 into through after the roughing, adopt bead-welding technology directly to generate the structure of semi arch watts 4 on the semicircle cambered surface at connecting rod.This structure, the screw of having avoided traditional semi arch watt 4 syndetons to produce becomes flexible phenomenon of rupture with pin, prolonged the service life of semi arch watts 4, reduced fault rate.Simultaneously, carry out Precision Machining, also can reduce production costs, shorten the production cycle owing to need not again the binding face and the connecting rod semicircle cambered surface seam 5 of double segmental tile 4 and connecting rod 1.
