Description
Technical Field
The invention relates to the field of spline shaft processing, in particular to a novel spline shaft upsetting forging die structure.
Background
In the existing spline shaft processing technology, a mode of locally heating and not heating a rod part is generally adopted. The diameter of the shaft part of the spline is the diameter of steel, the large end part (end part) is a deformation part which participates in deformation and needs to be heated to 1050-. After an operator utilizes the upsetting die to complete local deformation of a blank, the rod part is not provided with an ejection device, time and labor are wasted, the operator needs to take out the blank, the operator holds a pliers with hands during operation, the lever principle is used for prying out the blank by taking a point on the excircle of the upsetting die as a supporting point, the force of the pliers is not perpendicular to the direction of the blank, the blank is pulled by hand, each work can only be used for manufacturing 500 blanks, and the production efficiency is low.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides a novel spline shaft upsetting forging die structure which has the advantages of simple structure, high production efficiency and safe and reliable use.
The purpose of the invention is achieved by the following technical scheme: the novel integral key shaft upsetting forging die structure is used for upsetting blanks, one end of each blank is a rod part, the other end of each blank is an upsetting part, the structure comprises an upsetting upper die and an upsetting lower die, a blank channel is arranged in the upsetting upper die in a through mode, the inner diameter of the bottom of the blank channel is expanded to form a concave interface, a convex interface is arranged at the position, corresponding to the concave interface, of the top of the upsetting lower die, and the convex interface is in embedded fit with the concave interface, so that the upsetting upper die is supported on the upsetting lower die; a spring groove is formed in the convex connector and used for placing a spring, a step surface is arranged on the inner wall of the top end of the spring groove, the rod part of the blank is inserted into the blank channel and is propped against the step surface, and the upsetting part of the blank is exposed above the blank channel; one end of the spring is propped against the bottom of the spring groove, and the other end of the spring is propped against the end face of the rod part, so that the blank moves up and down along the blank channel.
As a further technical scheme, the top of the blank channel is provided with a upsetting die orifice for upsetting and forming the blank.
The invention has the beneficial effects that: the ejecting vertical force is ensured, the material taking efficiency is improved, and the integral efficiency of upsetting of the spline shaft is doubled.
Drawings
Fig. 1 is a schematic structural view of an upsetting upper die.
Fig. 2 is a schematic structural view of the upsetting lower die.
Fig. 3 is a schematic view of the blank as it enters the upset.
Fig. 4 is a schematic structural view of the blank after upsetting is completed.
Description of reference numerals: the upsetting die comprises an upsetting upper die 1, an upsetting lower die 2, a blank channel 3, a concave connector 4, a convex connector 5, a spring groove 6, a spring 7, a step surface 8, a blank 9, a rod part 9-1, an upsetting part 9-2 and an upsetting die opening 10.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example (b): as shown in the attached drawings, the novel spline shaft upsetting forging die structure is used for upsetting a blank 9, one end of the blank 9 is a rod part 9-1, the other end of the blank 9 is an upsetting part 9-2, and the structure comprises an upsetting upper die 1 and an upsetting lower die 2. As shown in fig. 1, a blank channel 3 is arranged in the upper upsetting die 1 in a penetrating manner, and the inner diameter of the bottom of the blank channel 3 is expanded to form a concave interface 4; as shown in fig. 2, a convex interface 5 is arranged at the position of the top of the upsetting lower die 2 corresponding to the concave interface 4, and the convex interface 5 is in embedded fit with the concave interface 4, so that the upsetting upper die 1 is supported on the upsetting lower die 2; a spring groove 6 is formed in the convex connector 5 and used for placing a spring 7, a step surface 8 is arranged on the inner wall of the top end of the spring groove 6, a rod part 9-1 of the blank 9 is inserted into the blank channel 3 and is propped against the step surface 8, and a upsetting part 9-2 of the blank 9 is exposed above the blank channel 3; one end of the spring 7 is pressed against the bottom of the spring groove 6, and the other end of the spring 7 is pressed against the end surface of the rod part 9-1, so that the blank 9 moves up and down along the blank channel 3. And a blank upsetting die orifice 10 is arranged at the top of the blank channel 3 and used for upsetting and forming a blank 9.
The working process of the invention is as follows: referring to the attached figure 3, during upsetting, the rod part 9-1 of the blank 9 is inserted into the blank channel 3, so that the end surface of the rod part 9-1 is abutted against the step surface 8, because the forging force is greater than the ejecting force of the spring 7 during forging the blank, the spring 7 is in a pressing state, and the upsetting part 9-2 is matched with the upsetting die opening 10 under the action of the forging force, so that the blank 9 is upset and formed. Referring to fig. 4, after upsetting is completed, forging is stopped, the spring 7 springs upwards to move the blank 9 upwards along the blank channel 3, and an operator can take the blank 9 out of the forging die structure through a pair of pliers to complete one upsetting operation.
It should be understood that equivalent substitutions and changes to the technical solution and the inventive concept of the present invention should be made by those skilled in the art to the protection scope of the appended claims.
