The following describes a specific implementation of the present invention in more detail with reference to specific embodiments:
referring to fig. 2, an embodiment of the present invention provides a manufacturing process of an eccentric nail 100 for manufacturing the eccentric nail 100. Referring to fig. 1, the eccentric pin 100 includes an eccentric table 110, and an eccentric rod 120 connected to one side of the eccentric table 110 in a thickness direction and close to an edge of the eccentric table 110, wherein a central axis L1 of the eccentric rod 120 is spaced apart from a central axis L2 of the eccentric table 110. Optionally, the eccentric table 110 is a circular table, the eccentric rod 120 is a circular rod, and a distance between the central axis L1 of the eccentric rod 120 and the central axis L2 of the eccentric table 110 is equal to an absolute value of a difference between a radius of the eccentric table 110 and a radius of the eccentric rod 120.
Specifically, the eccentric nail 100 manufacturing process includes blanking, shaping, and bending steps.
Referring to fig. 3 and 4, in the cutting step, the raw material plate 200 is cut into a blank plate 210, wherein the blank plate 210 includes a fixing plate 211 and a blank nail plate 212 connected to the fixing plate 211, and the blank nail plate 212 includes a blank table material 2121 connected to the fixing plate 211 and a blank rod material 2122 connected to the blank table material 2121.
Based on the above steps, the blank block material 2121 having a shape and a size similar to those of the eccentric block 110 and the blank rod material 2122 having a size similar to those of the eccentric rod 120 can be obtained by cutting the raw material plate 200, so that the processing is convenient, and the amount of waste generated can be reduced to a greater extent, thereby improving the utilization rate of the raw material plate 200 and facilitating the saving of the manufacturing cost.
Before the connection between the blank holder 2121 and the fixing plate 211 is cut, the fixing plate 211 can reliably support the blank nail plate 212, so that the blank nail plate can be smoothly unfolded for shaping, bending and the like. As shown in the figure, the fixing plate 211 optionally includes a supporting ring 2111 in an open ring shape and a plurality of supporting rods 2112 connected between the supporting ring 2111 and the blank material block 2121, so as to facilitate ensuring and improving the supporting effect of the fixing plate 211 on the blank nail plate 212, and facilitate conveniently achieving the subsequent connection between the blank material block 2121 or the forming material block 310 and the fixing plate 211.
In the shaping step, the blank nail plate 212 is shaped into the preform nail 300, wherein the preform nail 300 includes a molding bed 310 formed by shaping the blank bed 2121 and a molding rod 320 formed by shaping the blank rod 2122, the molding bed 310 has the same shape as the eccentric table 110, and the molding rod 320 has the same shape as the eccentric rod 120.
Based on this step, the shape and size of the molding material 310 can be similar (substantially same) to those of the eccentric table 110, and the shape and size of the molding rod material 320 can be similar (substantially same) to those of the eccentric rod 120. At this time, the molding material 310 and the molding material 320 are still on the same plane.
Referring to fig. 5 and 6, in the bending step, the preformed pin 300 is bent such that the forming rod 320 and the forming table 310 are disposed at an angle, and together form the eccentric pin 100.
Based on the steps, the forming rod 320 can be bent around the joint of the forming rod 320 and the forming platform 310, and forms a predetermined included angle (the predetermined included angle is usually 90 °) with the forming platform 310, so as to finally form the eccentric nail 100 with a desired shape and size, and the processing is convenient and has high processing precision.
In which the connection between the blank block 2121 or the forming block 310 and the fixing plate 211 may be cut before or after the bending step, which does not affect the final forming of the eccentric nail 100, and each has advantages.
For example, even if the blank holder 2121 is separated from the fixing plate 211 in the blanking step, the shaping step and the bending step may be performed on the independent blank holder 2121. Accordingly, the interference influence of the fixing plate 211 on the work can be substantially avoided in the shaping step and the bending step, and the unfolding of the shaping step and the bending step can be facilitated to some extent.
For example, after the shaping step, the molding bed 310 may be separated from the fixing plate 211, and then the individual preform pins 300 may be bent. Based on this, the blank block 2121/forming block 310 can be supported by the fixing plate 211 during the shaping step, so as to maintain the stability of the relative position of the blank nail plate 212, and thus, the blank nail plate 212 can be reliably shaped with accurate positioning; in the bending step, bending of the preformed nail 300 can be conveniently achieved independently of the fixing plate 211, and the operation is also convenient.
For another example, the molding member 310 may be separated from the fixing plate 211 after the bending step (i.e., after the eccentric pins 100 are substantially molded). Based on this, the relative position of the blank nail plate 212/preform nail 300 can be maintained stable during the molding of the eccentric nail 100, and multiple, repeated positioning is avoided, thereby facilitating the development of the respective step operations with high precision.
To sum up, the manufacturing process of the eccentric nail 100 according to the embodiment of the present invention may be performed by cutting the raw material plate 200 to form the blank nail plate 212, shaping the blank block 2121 and the blank rod 2122 to form the forming block 310 having a shape and a size substantially the same as those of the eccentric block 110 and the forming rod 320 having a shape and a size substantially the same as those of the eccentric rod 120, and bending the forming rod 320 to form the eccentric nail 100 at a predetermined angle at the joint of the forming rod 320 and the forming block 310. This eccentric nail 100 manufacturing process's processing is convenient, machining efficiency is higher, and can be based on raw materials board 200 shaping outstanding many precision relatively higher eccentric nail 100, and the waste material yield is few, and the face utilization ratio is higher to do benefit to the manufacturing cost of compression eccentric nail 100.
Referring to fig. 3 and 5, in the present embodiment, the fixing plate 211 is supported by the blanking supporting mold 400, and then the blank material 2121 or the forming material 310 is pushed by the pushing mold 500 to cut off the connection between the blank material 2121 or the forming material 310 and the fixing plate 211; the blanking support die 400 is provided with a first through blanking slot 401.
By adopting the above scheme, the blank support die 400 is firstly supported on one side of the fixing plate 211, and then the blank table material 2121 or the forming table material 310 is pushed by the pushing die 500 towards the direction close to the blank support die 400, so that the blank table material 2121 or the forming table material 310 is disconnected from the fixing plate 211, and then the blank nail plate 212/the preformed nail 300/the eccentric nail 100 are dropped out along the first blanking slot 401. The blanking embodiment is simple and convenient to operate, and can greatly reduce the damage to the blank nail plate 212/the preformed nail 300/the eccentric nail 100, so that the processing convenience, the processing efficiency and the processing precision of the eccentric nail 100 are guaranteed and improved.
Referring to fig. 3, 5 and 7, in the present embodiment, in the shaping step, the blank rod material 2122 is shaped by extrusion.
By adopting the above scheme, the accessible extrudees blank pole material 2122, and makes shape, the size of blank pole material 2122 satisfy and predetermine the requirement, is close to shape, the size of eccentric rod 120 promptly, and the machining precision is higher, and machining efficiency is higher.
Referring to fig. 3, 5 and 7, in the present embodiment, in the shaping step, the blank rod material 2122 is shaped by the extrusion die 600, wherein the extrusion die 600 includes a first extrusion die 610 and a second extrusion die 620 opposite to each other, and the first extrusion die 610 and the second extrusion die 620 can jointly enclose to form the shaping cavity 601 for extruding the blank rod material 2122 therebetween.
By adopting the above scheme, the shaping cavity 601 can be formed by mutually covering the first extrusion die 610 and the second extrusion die 620 which are oppositely arranged on two sides of the blank rod material 2122, based on this, the blank rod material 2122 can be extruded between the shaping cavity 601, and the deformation of the blank rod material 2122 is guided by the shape and the size of the shaping cavity 601, so that the shape and the size of the blank rod material 2122 are close to the shape and the size of the eccentric rod 120, the processing precision is high, and the extrusion die 600 can be adapted to the shaping operation of the blank rod materials 2122 with the same specification and large batch, thereby the processing efficiency can be improved.
Referring to fig. 3 and 4, in the present embodiment, in the shaping step, the blank block 2121 is thinned to form the forming block 310.
