Description

[Detailed description of the invention] Regarding press.

In conventional multistage presses, when a material is to be subjected to plastic processing, several punches and dies are attached using a tool set, and then the material is subjected to plastic processing.

For this reason, it is generally necessary to operate a guisent with a large shape and weight (H, 1), which requires a large amount of driving force, and the overall weight and shape of the device is large, making it extremely difficult to reduce the cost of the device. . In addition, the larger the size of the tool set, the longer it takes to make the mold, which lengthens the delivery time of the mold, which has a negative impact on product planning, and increases the cost of the mold, which must be added to the processed product, making it difficult to reduce processing costs. There were some problems.

The present invention was made in order to solve the conventional problems, and in other words, it enables multi-step machining of high-precision parts using only punches and dies, without using a tool set, which is the bottleneck for cost reduction. The purpose is to provide a multi-car forming press that can reduce the cost of equipment and processing costs, shorten the delivery time of processed products, and reduce equipment carrying costs.

Below, embodiments of the present invention will be described based on the drawings. (1
) is a fuselage, and one part of the fuselage (1) has a crank chamber (la) and a guide part (lb) below it. There is a bed part (lc) at the bottom of the body (1), and further below the bed part (1e) there is a leg part (1e), and a plurality of die mounting holes (1d) are provided in the bed part (1c). (2) is a holder body provided in the crank chamber (la), and the holder body (2) is interlocked with the crank mechanism part (3).

(4) is a plurality of punch holders, the upper part of the punch holder (4) is attached to the holder body (2), and the lower part thereof is inserted into the guide part (1b). Further, a threaded portion (4a) is provided at the second portion of the punch holder (4). In addition, the punch holder (4) is attached to the die mounting hole (
1d). (5) is a stroke adjustment mechanism part that is provided on the upper part of the punch holder (4) and is equipped with an adjustment nut (5a), a presser plate (5b
).

There are a key (5c), a washer (5d), a long nut (5e), etc., and the stroke is adjusted by moving the punch holder (4) in the axial direction. The stroke adjustment mechanism section (5) may have a structure other than the above. (6) is a bush provided on the guide section (lb) on which the punch holder (4) slides, and (7) is a punch mounting screw. be.

(8) is a two-wooden guide member that is slidably provided on the guide part (1b) of the body (1) and guides the holder body (2), and the guide member (8) has a bearing (9). A plurality of grooves (8a) in contact with the pole are provided in the axial direction. (10) is a fastening member such as a bolt or screw, (11
) is a punch, (12) is a die, and (13) is a spacer. (14) is a knockout mechanism provided at the bottom of the die attachment hole (1d) provided in the bed portion (1c). Knockout pin (+
4a), adjustment pole screwed into bed part (1c)) (
14b), the adjustment pin (14c) which is screwed together with the adjustment pole (14b), and a spring (14d) for α adjustment.The bed portion (1c) is equipped with a material supply device, a conveyance device, etc. (not shown). It is provided. Also, knockout 4
The 'l structure (14) is not limited to the above structure. (15) is the knockout drive shaft, (16) is the drive device, (17) is the flywheel, (+8), (+8
) is a belt.

Next, to explain the present invention in detail, first, the die (12) is set in the die mounting hole (1d) and the punch (11) is set in the die mounting hole (1d).
) to the punch holder (4) using the punch mounting screw (7). Next, the material is supplied to the die (12), and the punch (11) descends to perform the first step of plastic working on the material 1. Thereafter, the punch (11) is raised (4) and returned to its original position, and the material is transported to the die (12) for the next process by a transport device (not shown). Furthermore, the punch (11) performs a second process on the material 1 while operating downward.
A predetermined number of plastic workings are performed sequentially from the third step. The vertical movement of the sowing punch (11) is prevented from wobbling by the guide member (8), so that it operates accurately.

Next, to explain how to replace the mold, first of all, the die (12) set in the die mounting hole (1d)
Remove the punch (11) from the punch holder (4) by loosening the punch mounting screw (7) attached to the sharp punch holder (4). Then a new die (1
2) into the die mounting hole (ld) and the punch (11) into the punch holder (4). In this case, instead of using the previously used gui set, use the dice (12).
Only the punch (11) and the punch (11) need to be replaced. At this time, the punch holder (4) is independent, so to adjust each stroke, the length of the punch holder (4) is adjusted by turning the adjusting nut (5a). In addition, fine adjustment of the stroke enables high-precision machining.

As described above, the present invention provides a holder main body (2) interlocking with the crank mechanism part (3) in the crank chamber part (1a) of the machine body (1), 1: part, and the holder main body (2) is When guided by the guide member (8) slidably provided on the lower guide part (lb), the upper parts of the plurality of punch holders (4) with the guide parts (1b) inserted through them are also attached. In addition, the punch holder (4) is equipped with a stroke adjustment '!I1 mechanism (5) on the top of the punch holder (4) that can independently adjust its stroke. By providing multiple die mounting holes (1d) facing the punch holder (4) and equipping the lower part with a knockout mechanism (14), the stroke of the punch holder (4) for each process can be adjusted, which is different from conventional use. Plastic processing of the material can be done simply by setting each die (12) and punch (11) facing each other without using the heavy force set used previously.For this reason, there is no need for a force set, and even if the driving force is small, the material can be processed plastically. Can be processed efficiently,
The weight and size of the entire device is reduced, the cost of the device is reduced, and Gold JI! ! For manufacturing, it is only necessary to manufacture the die (12) and punch (11), and the delivery time for the mold is extremely shortened, and the cost of the mold is also reduced. Therefore, it is possible to reduce the equipment price and the mold price, and also to reduce the processing cost.In addition, the delivery time of the processed product and the maintenance cost of the equipment can be reduced.

In addition, compared to conventional presses whose energy is absorbed by the forceps, springs, etc., resulting in poor pressurizing efficiency, the press of the present invention has many advantages such as the pressurizing force being applied directly to the material, resulting in good pressurizing efficiency. This will bring out the effects of this.
