Abstract

The utility model discloses a main structure shape bending die for a miniature motor junction box. The main structure shape bending die comprises an upper die set, a lower die block, a lower die, a first lower die insert, a second die insert and a positioning plate, wherein the upper die set adopts a gantry-shaped bracket; the width of a gantry pile is smaller than that of an opening of a shape-bent part; the upper die block is provided with a groove which is matched with a beam of the gantry-shaped bracket and screwed with the beam of the gantry-shaped bracket through three bolts; the first lower die insert, the second lower die insert and the positioning plate are arranged on the lower die; and the second lower die insert is higher than the first lower die insert. The main structure shape bending die has the advantages that: 1, materials are saved; 2, production efficiency is improved, and a bent board can be manufactured only by the twice shape bending of the shape bending die; and 3, the use of high-end equipment is reduced, universal ordinary oil hydraulic pressure is used for finishing work which can be finished only by special equipment, a good appearance forming effect is achieved, dimensional accuracy completely meets a design requirement, procedures are reduced, production time is saved, the production efficiency is improved, and the performance of a motor is ensured.

Description

The bent type die of a kind of miniature motor terminal box main structure

Technical field

The utility model relates to motor and makes the field, is a kind of bent type die of main structure that realizes the miniature motor terminal box specifically.

Background technology

Recently motor development is very fast, and minitype explosion-proof motor is more and more littler, and the volume of motor connecting cartridge is also more and more littler; Terminal box generally adopts multiplex's part solder technology, and workpiece uses more; Welding space and welding position wretched insufficiency, weld defect too much and some positions can't weld, have a strong impact on explosion prevention function.Therefore we press for a kind of process of miniature motor terminal box, avoid the generation of above situation.The bent type of terminal box bent plate is the bent type of asymmetric shape, and part drawing is as shown in Figure 1, and this part is asymmetric shape; The bent type of graded, the bent top of elder generation, bent lower part, back; Curve one side in top does not have straight line 50, and the location is convenient during for bent type, needs to increase straight line part 50; Blank size will correspondingly extend, and is processed into required form with machine-tooled method again behind the bent type, and bent type shape is as shown in Figure 2 behind the increase straight line.

The utility model content

For solving the problems of the technologies described above, the purpose of the utility model provides the bent type die of a kind of miniature motor terminal box main structure, and concrete scheme is following:

The bent type die of a kind of miniature motor terminal box main structure comprises top mold frame 1, last model block 4; Counterdie 6; Counterdie inserts 1, counterdie is inserted 25, location-plate 2, top mold frame 1 employing gantry shape support, the width of top mold frame 1 column less than bent type after the A/F of part; Last model block 4 is provided with a groove 11 and cooperates with the portal frame crossbeam, is spirally connected with three bolts again, is provided with on the counterdie 6 that counterdie inserts 1, counterdie is inserted 25, location-plate 2; Counterdie is inserted and 25 is higher than counterdie and inserts 1.

The utility model has the advantages that: 1. economical with materials; 2. enhance productivity, this bent plate uses this bent type frock only to need twice bent type of a cover frock to accomplish; 3. saving high-end devices adopts this structure can use general conventional oil press, accomplishes the work of having only special equipment to accomplish; Use the new technological measure and the bent plate of bent type frock making, the outward appearance molding effect is very good, and dimensional accuracy reaches designing requirement fully, and practices thrift operation and production time, has improved production efficiency, has guaranteed the performance of motor, has adapted to the demand in market.

Fig. 5 is that counterdie, counterdie insert one, counterdie is inserted two structural representations.

The specific embodiment

Specify the utility model below in conjunction with accompanying drawing; Like Fig. 3, Fig. 4, shown in Figure 5, the utility model comprises top mold frame 1, last model block 4; Counterdie 6; Counterdie inserts 1, counterdie is inserted 25, location-plate 2, top mold frame 1 employing gantry shape support, the width of top mold frame 1 column less than bent type after the A/F of part; Last model block 4 is provided with a groove 11 and cooperates with the portal frame crossbeam, is spirally connected with three bolts again, is provided with on the counterdie 6 that counterdie inserts 1, counterdie is inserted 25, location-plate 2; Counterdie is inserted and 25 is higher than counterdie and inserts 1.

Top mold frame 1 adopts No. 45 steel, because counterdie institute is stressed very big in getting the type process, in order to improve the force intensity that receives of counterdie, counterdie adopts the form of inserting; Two materials that counterdie inserts one, counterdie is inserted are and adopt CrWMn, and counterdie 6 adopts HT250, and remaining part adopts Q235-A carbon steel.

The principle of the utility model is: because the left side is one section curve during the bent type of the shape of this part, the right side is a straight line, in order to make part stress equalization in bent type process; Prevent moving when part is bent type, counterdie is designed to stairstepping, and steel plate is the initial V-type that is deformed on counterdie; Along with moving downward of patrix; Part and counterdie are inserted and two are contacted, and left side part and counterdie are inserted and one contacted simultaneously, and the both sides stressed part stress that makes of while is kept in balance.Moving to opening part behind the part forming revolves to turn 90 degrees along column again and takes out.

The concrete bent type step of the utility model:

(1). by the technological requirement blanking;

(2). the cleaning surface of the work, and smooth to workpiece;

(3). workpiece is placed on the frock relevant position;

(4). movement of the foetus is done in the control, moves to the final position;

(5). movement of the foetus is done in the control, returns back to bent type front position;

(6). again workpiece is placed on the frock relevant position;

(7). repeat operation (3), (4), bent type operation finishes;

Through test, the terminal box economical with materials weight of the utility model preparation is about 41 percent, has alleviated the weight of terminal box, the weight of motor greatly; Terminal box contour dimension reduces obviously, and effective usable floor area obviously increases in the terminal box, and operation reduces, and welding capacity reduces, and explosion-proof reliability promotes significantly, has guaranteed the performance of motor.

Claims

1. the bent type die of miniature motor terminal box main structure is characterized in that: comprise top mold frame, last model block; Counterdie; Counterdie inserts one, counterdie is inserted two, location-plate, and top mold frame adopts gantry shape support, the width of top mold frame column less than bent type after the A/F of part; Last model block is provided with a groove and cooperates with the portal frame crossbeam, is spirally connected with three bolts again, is provided with on the counterdie that counterdie inserts one, counterdie is inserted two, location-plate; Counterdie is inserted and two is higher than counterdie and inserts one.
