Description
Technical field
The present invention relates to a kind of battery pole piece roll method for upsetting, belong to roll technical field of forging.
Background technique
In roll product, battery pole piece roll is for rolling battery pole piece.Because of the needs of roll electrode, roll shape used
Shape is different from roll used in other pair rollings, and middle part barrel diameter is big compared with both ends roller diameter diameter drop, to meet product forging
Requirement is made, guarantees product quality, the forging method of gathering stock need to be taken, by the gathering stock deformation to body of roll position come real
The big drop of the existing body of roll and roller diameter.After gathering stock, body of roll blank forms single-drum type, is shaped by the pulling in later period, finally
Two vertex angle part of the body of roll easily forms fillet and misrun, the misrun situation in body of roll corner cause difficulty to the machining in later period, only
The formation that energy perhaps increase the multiple jumping-up body of roll of production fire time by increasing body of roll materials, which is improved, causes material or the energy
Waste, production efficiency are low.
Summary of the invention
The object of the present invention is to provide a kind of battery pole piece roll method for upsetting, to solve above-mentioned technical problem, are guaranteeing
Under the premise of roll quality, material and the energy the waste is reduced, improves production efficiency.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of battery pole piece roll method for upsetting, battery pole piece roll include the integrally formed roll neck of the body of roll and body of roll both ends, roller
Body diameter is greater than roll neck diameter, makes the body of roll using the method for gathering stock；It is pre- in the root that the body of roll connects with roll neck when blanking
Stay clout；Drain cap is utilized when jumping-up, under the inner hole effect of drain cap, is reserved clout and is generated flowing, be configured to body of roll root；Former roller
Body root blank is flowed to body of roll corner, is formed corner and is generated protrusion.
Technical solution of the present invention further improvement lies in that: reserved clout is the fillet of the body of roll and roll neck intersection.
Technical solution of the present invention further improvement lies in that: the radius of corner of reserved clout is the 0.5 of drain cap internal bore radius
~0.8 times.
Technical solution of the present invention further improvement lies in that: body of roll corner protrusion protrusion body surface height be 10~
20mm。
Technical solution of the present invention further improvement lies in that: further include subsequent pulling process；It will by pulling process
Boss is trimmed to body of roll right angle.
By adopting the above-described technical solution, the technical effect that the present invention obtains has:
The present invention reserves clout in body of roll root in blanking, carries out gathering stock using drain cap in jumping-up.In drain cap inner hole
Under the action of, the reserved clout touched can be made to generate flowing, be configured to body of roll root, and former body of roll root blank is also therewith
It is flowed to body of roll corner, ultimately forms corner and generate protrusion, boss can be trimmed to by roller by subsequent pulling process
Body right angle.
Reserved clout in the present invention is round, is further limited by the relationship of the internal bore radius with drain cap
The radius of fillet, and then ensure that body of roll corner generates protrusion and can reach requirement, and body of roll corner in subsequent pulling process
Right angle is formed, the structure of the body of roll on the whole meets design requirement.
The height of the protrusion protrusion body surface in body of roll corner is 10~20mm in the present invention, and the protrusion of the height is subsequent
Pulling during can be modified to body of roll right angle, to avoid the occurrence of due to misrun and influence the subsequent of battery pole piece roll
Machining.
Process of the invention, which is compared with the traditional method, can save raw material, reduce production cost, improve the benefit of material
With rate；Fire when jumping-up can also be reduced, to reduce the time of processing, improves the efficiency of processing.
Detailed description of the invention
Schematic diagram when Fig. 1 is jumping-up of the present invention processing；
Wherein, 1, the body of roll, 2, roll neck, 3, drain cap, 4, clout.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further details the present invention:
It is for processing and fabricating battery pole piece roll the invention discloses a kind of battery pole piece roll method for upsetting.Here is
Specific embodiment:
The present invention is a kind of battery pole piece roll method for upsetting, for making battery pole piece roll.Battery pole piece roll includes roller
The integrally formed roll neck 2 of body 1 and 1 both ends of the body of roll, 1 diameter of the body of roll are greater than 2 diameter of roll neck.Diameter between the body of roll 1 and roll neck 2 is fallen
Difference is larger, makes the body of roll 1 using the method for gathering stock.
The problem of being directed to background technique, when processing method blanking, are pre- in the root that the body of roll 1 connects with roll neck 2
Stay clout 4.Gathering stock is carried out to blank using drain cap 3, drain cap 3 is provided with inner hole, and the diameter of the body of roll 1 is greater than the interior of drain cap 3
Hole cannot pass through, and the inner hole that the diameter of roll neck 2 is less than drain cap 3 can pass through.When jumping-up, under the inner hole effect of drain cap 3, reserve
Clout 4 generate flowing, be configured to body of roll root；Former body of roll root blank, which is squeezed, presses to the flowing of body of roll corner, forms corner simultaneously
Generate protrusion.Specifically as shown in Figure 1, the direction of arrow meaning is the direction of clout flowing in Fig. 1.It is common, the method for upsetting
Pulling process is provided in subsequent processing；Boss is trimmed to body of roll right angle by pulling process.
In specific implement, the fillet that clout 4 is the body of roll 1 and 2 intersection of roll neck is reserved, i.e., is increased original right angle
Add clout 4 and is set as fillet.Under normal conditions, the diameter of the fillet of reserved clout 4 is the diameter according to the inner hole of drain cap 3
Come what is determined, the radius of corner of reserved clout 4 is 0.5~0.8 times of the internal bore radius of drain cap 3.It is remaining under the structure setting
Material 4 smoothly can smoothly flow under the action of drain cap, and then 1 corner of the body of roll is made to generate protrusion, in subsequent pulling process
In prevent body of roll corner misrun.
The height on protrusion protrusion 1 surface of the body of roll in 1 corner of the body of roll is 10~20mm in the present invention, and the protrusion of the height is rear
Body of roll right angle can be modified to during continuous pulling, be not in that the subsequent machine of battery pole piece roll is influenced due to misrun
Tool processing.
Reserved clout in the present invention is designed as round, and ensures that is produced from body of roll corner by the diameter of restriction fillet
Raw protrusion can reach requirement, and body of roll corner forms right angle in subsequent pulling process, and the structure of the body of roll on the whole meets
Design requirement.The radius of corner of reserved clout is 0.5~0.8 times of the internal bore radius of drain cap, and office can either be met under the setting
Clout flowing forms protrusion for the forming facilitation at subsequent pulling process body of roll right angle in the body of roll corner when portion's jumping-up, and not
It excessively causes to waste as clout.
The present invention limits the fillet diameter of reserved expectation by the diameter of bore of drain cap, can be convenient to carry out, while energy
Enough satisfy the use demand.
