Abstract
The invention belongs to the technical field of stamping, and particularly relates to a stamping workshop process layout scheme adopting double-crown-block flying-wing type die change. According to the layout, the stamping line and the die storage area are divided into three spans, the stamping line spans in the middle, the die storage areas are respectively located on two spans on two sides of the stamping line, and the workbench of the stamping line can be opened into the two die storage areas of the adjacent spans. The dies of each part are stored in die storage areas on two sides of the stamping line in sequence, and the dies stored on two sides of the stamping line are replaced by two crown blocks respectively during working. The process layout can reduce the time for changing the die outside the stamping workshop line by about 40 percent, isolate the die storage area and reduce the safety risk of a crown block to people, and meanwhile, the layout can adopt the full-automatic die changing of the crown block to further reduce the time for changing the die outside the stamping workshop line.
Description
Technical Field
The invention belongs to the technical field of stamping, and particularly relates to a stamping workshop process layout scheme adopting double-crown-block flying-wing type die change.
Background
With the continuous development of stamping equipment, the stamping line is required to really obtain higher production efficiency, which not only depends on the design level of the stamping line, but also has a great relationship with the die change time of stamping production. The die change time refers to the interval time from the last stamping part produced by the former die set to the first stamping part produced by the next die set, and can be divided into in-line die change time and out-of-line die change time. At present, the in-line die change time of a stamping line can be controlled within 3 minutes, and the out-line die change time depends on the process layout mode of a stamping workshop. One stamping line needs to change the die at least 12 times every day, so that the reduction of the off-line die change time is very important to improve the stamping production efficiency.
The process layout of most of the current stamping workshops in China is that a die storage area and a stamping line are arranged in the same span, and the die storage area is generally positioned at the head of the stamping line, as shown in the attached figure 1. The punching line is provided with two working tables which can be opened left and right. And when the mold is changed, a crown block is adopted to hoist the produced mold to the mold storage area, and the next mold to be produced is hoisted to the workbench to wait. Taking a 6-process stamping line as an example, the off-line die change time required by the process layout is generally about 120 minutes, and the influence on the production efficiency and the production batch of a stamping workshop is very large.
Disclosure of Invention
The invention provides a process layout scheme of a stamping workshop adopting double-crown-block flying wing type die changing, which improves the die changing efficiency outside the stamping workshop line and solves the defects of the traditional stamping workshop.
The technical scheme of the invention is described as follows by combining the attached drawings:
a stamping workshop process layout scheme adopting double-crown-block flying-wing type die change comprises a die storage area A, a die storage area B, a crown block 1, a crown block 2 and a stamping line working area; the die storage area A and the crown block 1 are arranged on one side of the stamping line; the die storage area B and the crown block 2 are arranged on the other side of the stamping line;
when the crane works, the crown block 1 and the crown block 2 respectively replace the molds stored in the mold storage area A and the mold storage area B; the mold storage area A is provided with a waiting area A and a mold changing area A; the mold storage area B is provided with a waiting area B and a mold changing area B; the crown block firstly opens the workbench into a waiting area for plugging and unplugging the Harding joint and assembling and disassembling the clamp, and then opens into a die changing area for die changing.
The mould storage area A stores moulds with odd serial numbers; the mold storage area B stores molds with even serial numbers; the total number of the molds stored in the mold storage area A and the mold storage area B is less than or equal to 6 sets.
And the crown block 1 and the crown block 2 adopt full-automatic die changing crown block die changing.
The invention has the beneficial effects that:
1. the process layout scheme of the invention reduces the external die change time of the stamping workshop line by about 40%.
2. The process layout scheme of the invention can realize complete isolation of the die storage area, realize unmanned die storage area and reduce the safety risk of the crown block to people.
3. The running track of the die change crown block used by the invention has no intersection with other logistics in a workshop, so that the full-automatic die change crown block can be used for die change (no person is allowed in the running area of the full-automatic die change crown block), and the full-automatic crown block can not be used in the traditional process layout.
4. The traditional stamping production can only use one crown block for die change, and the process layout scheme of the invention can use two crown blocks for die change, thereby greatly improving the production efficiency.
Drawings
FIG. 1 is a schematic view of a conventional stamping shop process layout;
FIG. 2 is a schematic diagram of the process layout of a stamping workshop adopting double overhead traveling crane flying wing type die change according to the invention.
Detailed Description
Examples
Referring to fig. 2, this embodiment is provided with 6 sets of molds.
The whole stamping workshop is divided into three spans, the stamping line and the die storage area are arranged in a spanning mode, the stamping line spans in the middle, the die storage area A and the die storage area B span in the rest two spans, and a workbench of the stamping line can be opened into the two die storage areas with different spans. The dies of each part are stored in die storage areas on two sides of the stamping line in sequence, for example, the dies of the fender are stored in six sequence, the first, third and fifth sequence are stored in a left die storage area A, the second, fourth and sixth sequence are stored in a right die storage area B, and the dies stored on two sides of the stamping line are respectively replaced by two full-automatic crown blocks during operation.
The working process of the invention is as follows: when the last stamping part is produced by the current set of dies, the workbench in the stamping line takes the dies which are just produced to open the stamping line, the dies are respectively opened into the die storage areas on the left side and the right side, the workbench waiting outside the stamping line takes the dies to be produced to open the stamping line for production, and at the moment, the fully-automatic crown block starts to replace the dies.
The crown block 1 unloads the first-order, third-order and fifth-order moulds on the workbench and puts the moulds into the mould storage area A, and the next first-order, third-order and fifth-order moulds to be used for producing parts stored in the mould storage area A are conveyed to the workbench to wait. Meanwhile, the crown block 2 unloads the second, fourth and sixth-order molds on the workbench and puts the second, fourth and sixth-order molds into the mold storage area B, and conveys the next second, fourth and sixth-order molds to be produced in the mold storage area B to the workbench for waiting, and at this moment, the whole mold changing process is finished.
The process layout scheme can reduce the time for changing the die outside the stamping workshop line by about 40 percent, isolate the die storage area and reduce the safety risk of a crown block to people, and meanwhile, the layout can adopt full-automatic die changing of the crown block to further reduce the time for changing the die outside the stamping workshop line.
