Problems solved by technology

During the side punching process, the side punch will exert force on the stamping concave part of the lower die. When only one side of the shell parts needs to be punched or due to the processing accuracy and assembly accuracy of the lower die itself , leading to uneven force on the lower die, prone to tilt or offset, and then easy to cause side punch breakage and damage to the lower die, making production unable to continue
At the same time, it also affects the lateral punching quality of shell parts, which increases the burrs in the punching parts of shell parts and increases the rate of defective products.
When the vehicle-mounted power supply housing parts are subjected to side punching, the increased burrs will reduce the accuracy of the housing parts, and the cumulative error will increase after the assembly of other parts and housing parts. Even if the vehicle-mounted power supply can be assembled, But it will bring job instability
In the use of vehicles, there are potential hidden dangers that may cause dangers such as overload and short circuit.

Embodiment 1

[0053] Such as Figure 1 to Figure 8 As shown, a side-punching balance mechanism for vehicle-mounted power supply casing parts includes a lower die base 1 , a lower die base balance locking mechanism 3 and a side punching mechanism 4 .

[0054] The lower mold base 1 is used to cover the housing parts 5 on the lower mold base 1 , and the side of the lower mold base 1 is provided with a stamping recess 11 .

[0055] The lower mold base balance locking mechanism 3 is used to fix the lower mold base 1;

[0056] The side punching mechanism 4 is used for side punching the shell parts 5 pressed on the lower mold base 1 .

[0057] The side punching balance mechanism of the present invention adds a lower mold base balance locking mechanism 3, and the lower mold base 1 is fixed by the lower mold base balance locking mechanism 3. When the side punching mechanism 4 performs side punching on the shell parts 5 , It can ensure that the lower die base does not shift, shake, or skew after be...

Embodiment 2

[0083] The difference between this embodiment 2 and embodiment 1 lies in the specific structure of the balance locking mechanism of the lower mold base, and the special anti-blocking mechanism for waste materials has been cancelled.

[0084] In this embodiment 2, aiming at the case that there is a central hole at the bottom or the top of the casing parts, this embodiment 2 provides another specific structure of the balance locking mechanism of the lower mold base. Such as Figure 9 , Figure 10 As shown, the balance locking mechanism of the lower mold base includes an upper mold, a positioning pin 35 and a guide pin hole 36 arranged on the lower mold base 1 and arranged along the central axis of the lower mold base. The positioning pin 35 is fixed on the upper mold base by a fixed block 34 On the mold, driven by the upper mold to move up and down, the positioning pin 35 is used to move downwards under the drive of the upper mold and penetrates in the guide pin hole 36, wherei...

Embodiment 3

[0090] On the basis of the side impact balance mechanism of the automobile on-board power supply casing parts of embodiment 1, such as Figure 11 to Figure 13 As shown, a side punching method for shell parts includes the following steps:

[0091] Step S1, putting the shell parts 5 on the lower mold base 1;

[0092] Step S2, using the lower mold base balance locking mechanism 3 to fix the lower mold base 1; the lower mold base balance locking mechanism 3 includes an upper mold, a first wedge 31, a first slider 32 and a clamping block 33;

[0093] Step S3, using the side punching mechanism 4 to carry out side punching on the shell parts 5 pressed on the lower die base 1, the side punching mechanism 4 includes an upper die, a second wedge 41, and a second slider 42 And the punch 43, the second oblique wedge 41 and the first oblique wedge 31 have a common upper mold.

[0094] After the step S1, a step T1 is also included, using the pushing and unloading mechanism 2 to press the ...

Abstract

The invention discloses a side punching and balancing mechanism and a side punching method for automobile vehicle-mounted power supply shell type parts. The mechanism comprises a lower mold base, a lower mold base balance locking mechanism and a side punching mechanism, wherein the shell type parts are arranged on the lower mold base in a sleeve mode, and the side surface of the lower mold base isprovided with a punching concave portion; the lower mold base balance locking mechanism is used for fixing the lower mold base; and the side punching mechanism is used for carrying out side punchingon the shell parts pressed on the lower mold base. According to the mechanism, the side punching and balancing mechanism is additionally provided with the lower mold base balance locking mechanism, and the lower mold base is fixed through the lower mold base balance locking mechanism, when the side punching mechanism is used for carrying out side punching on the shell type parts, the lower mold base can be ensured not deviated, shaken and inclined after being stressed, and the vertical direction is kept; the roundness of the side punching circular holes is guaranteed, and the precision of thespecial-shaped holes is guaranteed; and the the lower mold base is stably arranged, the service lives of the lower mold base and a male mold can be guaranteed, the punching smoothness is guaranteed, the production efficiency is improved, punching burrs of products are reduced, and the product quality is improved.

Description

technical field [0001] The invention relates to a side impact balancing mechanism and a side impact method for automobile vehicle-mounted power supply casing parts, and belongs to the technical field of vehicle vehicle power supply side impact. Background technique [0002] For some automotive power supply housing parts, side punching is often required during production. During side punching, the shell parts are placed on the lower die and punched directly through the side punch. During the side punching process, the side punch will exert force on the stamping concave part of the lower die. When only one side of the shell parts needs to be punched or due to the processing accuracy and assembly accuracy of the lower die itself , resulting in uneven stress on the lower die, prone to inclination or offset, which in turn may easily cause the side punch to break and the lower die to be damaged, making it impossible to continue production. At the same time, it also affects the l...
