Description

Technical Field

[0001] The utility model belongs to the field of drawing dies, and particularly relates to a full-air-top detection device for drawing dies. Background Art

[0002] In the cold stamping die process, the first process generally adopts a single-action drawing process, that is, after the press uses an air top to lift the blank holder, the blank holder and the upper die clamp the sheet metal, and then the sheet metal contacts the punch to form. During the production of the single-action drawing die and the commissioning of the die when it returns to the factory, different presses are used respectively. When the drawing die is produced in the die factory, only the necessary air tops need to be arranged to meet the production commissioning. However, when the die returns to the busbar factory for commissioning and production, the presses used generally have air tops arranged on the full table. Whether there is interference between the die and the full-air-top press needs to be verified in advance during the pre-acceptance process of the die.

[0003] Generally, the die factory does not have a full-table air top. During verification, a series of operations such as moving the workbench out of the press, lifting the die, changing the position of the air top, placing the die, and moving the workbench into the press need to be repeated for verification, which is time-consuming and laborious;

[0004] Moreover, the diameters of the air top rods of the presses in the die factory are not exactly the same as those of the customer's busbar air top rods. The verification of the presses in the die factory can only be a rough verification and cannot completely avoid the busbar interference problem;

[0005] Using machining equipment in the die factory for verification is also time-consuming and laborious; Content of the Utility Model

[0006] In view of this, the utility model aims to provide a full-air-top detection device for drawing dies to solve at least one technical problem in the background art.

[0007] To achieve the above object, the technical solution of the utility model is realized as follows:

[0008] A full-air-top detection device for drawing dies includes a detection backing plate and detection air top rods. A number of detection air holes are provided on the test backing plate; the detection air holes correspond to the detection holes of the press backing plate used in production;

[0009] The detection air holes are consistent with the detection holes of the press backing plate used in formal production;

[0010] The detection backing plate is arranged at the bottom of the lower die. The detection air top rods are inserted into the air top holes of the lower die through the detection air holes. If the insertion depth is greater than the air top ejection height, there is no interference; otherwise, there is interference.

[0011] The air top ejection height is the ejection height when the air top rod reaches the blank holder of the die during production.

[0012] Further, the detection air jack rod includes a tube body and a handle; the handle is arranged at the top of the tube body.

[0013] Further, the outer diameter of the tube body corresponds to the diameter of the detection air hole.

[0014] Further, one end of the detection backing plate is provided with a first installation groove, and the middle part of the detection backing plate is provided with a second installation groove. The second installation groove divides the detection backing plate into two parts;

[0015] The lower die of the drawing die is provided with a first installation block and a second installation block corresponding to the first installation groove and the second installation groove respectively. The detection backing plate is connected to the lower die of the drawing die through the first installation groove and the second installation groove.

[0016] Further, several first positioning blocks are provided on the first installation groove of the detection backing plate, and several second positioning blocks are provided on the second installation groove of the detection backing plate.

[0017] The lower die of the drawing die is provided with a first positioning groove and a second positioning groove corresponding to the first positioning block and the second positioning block respectively.

[0018] Compared with the prior art, the full air jack detection device for the drawing die of the present utility model has the following advantages:

[0019] 1. This application no longer occupies the working hours of the die factory for debugging the press. Since the number of air jack rods for debugging the press in the die factory is limited, it is necessary to repeatedly lift, arrange the air jack rods, place the die, lift and detect, and then repeat the above steps. Generally, it saves 4 hours of press usage time, 4 hours of overhead crane usage time, and 12 hours of manual working hours;

[0020] 2. This application less occupies the working hours of the overhead crane and avoids the long-term occupation of the workshop overhead crane in the prior art due to frequent lifting, which affects production;

[0021] 3. This application improves work efficiency. It takes 6 - 8 hours to detect a set of medium and large-sized dies in the traditional way, and it is estimated that it takes 2 hours to detect a set of medium and large-sized dies in this invention, saving the working hours of overhead crane operators, fitters, press operators and other personnel.

[0030] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0031] As Figures 1 to 3 shown, the full air jack detection device for the drawing die includes a detection backing plate 2 and a detection air jack rod 3. A plurality of detection air holes are provided on the test backing plate; the detection air holes correspond to the detection holes of the press backing plate used in production;

[0032] The detection air holes are consistent with the detection holes of the press backing plate used in formal production;

[0033] The detection backing plate 2 is arranged at the bottom of the lower die 1. The detection air jack rod 3 is inserted into the air jack hole of the lower die 1 through the detection air hole. If the insertion depth is greater than the air jack ejection height, there is no interference; otherwise, there is interference.

[0034] The air jack ejection height is the ejection height when the air jack rod touches the binder ring of the die during production.

[0035] The detection air jack rod 3 includes a tube body 8 and a handle 9; the handle 9 is arranged at the top of the tube body 8. The outer diameter of the tube body 8 corresponds to the diameter of the detection air hole.

[0036] One end of the detection backing plate 2 is provided with a first installation groove 4, and the middle part of the detection backing plate 2 is provided with a second installation groove 5. The second installation groove 5 divides the detection backing plate 2 into two parts; on the lower die 1 of the drawing die, there are a first installation block and a second installation block corresponding to the first installation groove 4 and the second installation groove 5 respectively. The detection backing plate 2 is connected to the lower die 1 of the drawing die through the first installation groove 4 and the second installation groove 5.

[0037] A plurality of first positioning blocks 6 are provided on the first installation groove 4 of the detection backing plate 2, and a plurality of second positioning blocks 7 are provided on the second installation groove 5 of the detection backing plate 2. The lower die of the drawing die is provided with a first positioning groove and a second positioning groove corresponding to the first positioning block 6 and the second positioning block 7 respectively.

[0038] When verifying the interference of the full air top of the drawing die in the mold factory, only the lower die 1 of the drawing die needs to be turned over, and then the full air top backing plate is placed in the second installation groove 5. The second installation groove 5 is placed on the turned-over lower die, and then the full air top detection air top rod 3 is inserted one by one according to the backing plate air top holes. If the insertion depth is greater than the air top ejection height, there is no interference; otherwise, there is interference. After the left side is detected, the same operation is performed on the right side.

[0039] This application no longer occupies the working hours of the mold factory for debugging the press. Since the number of air top rods for debugging the press in the mold factory is limited, it is necessary to repeatedly lift, arrange the air top rods, place the mold, lift and detect, and then repeat the above steps. Generally, 4 hours of press usage time, 4 hours of overhead crane usage time, and 12 hours of manual working hours are saved; this application less occupies the overhead crane working hours and avoids the long-term occupation of the workshop overhead crane in the prior art due to frequent lifting, which affects production; this application improves work efficiency. It takes 6 - 8 hours to detect a set of medium and large-sized molds in the traditional way, and it is estimated that it takes 2 hours to detect a set of medium and large-sized molds in the present invention, saving the working hours of overhead crane operators, fitters, press operators and other personnel.
