Description

Technical Field

[0001] The present invention relates to the technical field of automobile part processing, and particularly relates to a punching die for an automobile door guide rail. Background Art

[0002] The metal sheet shown in the attached drawings of the specification is one of the products processed by our company. During actual processing, a process groove needs to be processed at the end of this metal sheet by a hydraulic press in cooperation with a punching die. At present, due to the relatively simple and conventional structure of the punching die used, only the punching process can be performed on one end of a single metal sheet during a single stamping. When performing the punching process on the other end of the metal sheet, it is necessary to manually turn the metal sheet and stack it neatly after processing, which is quite time-consuming and laborious, restricting the part processing efficiency and part loading and unloading efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a punching die for an automobile door guide rail to solve the above-mentioned defects in the prior art.

The second upper die block is correspondingly arranged directly above the second forming groove.

[0010] Preferably, the positioning mechanism includes a second mounting plate, a second hydraulic cylinder, a positioning bar and a clamping bar. The second mounting plate is in a "┴" shape and is mounted in the middle on the top of the through groove. The second hydraulic cylinder is vertically downwardly mounted outside the second mounting plate. The end of the piston rod of the second hydraulic cylinder is connected with a first hinge seat.

A plurality of first magnet blocks are embedded in the lower part of the positioning bar. There are a pair of clamping bars, which are symmetrically arranged on the front and back sides of the positioning bar. A plurality of second magnet blocks are embedded in the lower part of the clamping bar. The first magnet blocks and the second magnet blocks attract each other.

The positioning bars on both sides are used to temporarily position the metal sheets in the left - right direction, and the clamping bars on both sides are used to temporarily clamp the metal sheets in the front - back direction.

[0014] 2. For the loading and unloading mechanism: The piston rod of hydraulic cylinder three extends and drives the flipping bar to flip upwards by a certain degree, so that the front and rear rows of vacuum suction cups correspondingly adsorb to the sides of the front and rear metal sheets. Then, the piston rod of hydraulic cylinder three contracts and drives the flipping bar to flip downwards by a certain degree, so that the front and rear rows of vacuum suction cups automatically load the two adsorbed metal sheets into the positioning grooves of the lower modules on the front and back sides.

[0015] 3. For the die mechanism: The piston rod of hydraulic cylinder one extends and drives the upper module one and upper module two to penetrate the metal sheet downwards and correspondingly insert into the forming grooves one and two of the lower module, thereby punching out process grooves one and two correspondingly at the ends of the metal sheet.

[0038] In this embodiment, the loading and unloading mechanism 40 includes a mounting plate 3 401, a hydraulic cylinder 3 402, a flip bar 407 and a vacuum suction cup 408. The mounting plate 3 401 is provided with a pair and is correspondingly provided above a pair of avoidance grooves 10b. The end of the mounting plate 3 401 is installed on the upper side of the mounting platform 10. The hydraulic cylinder 3 402 is provided with a pair and is symmetrically distributed on the left and right. The hydraulic cylinder 3 402 is vertically installed on the outside of the mounting plate 3 401. The end of the piston rod of the hydraulic cylinder 3 402 is connected to the mounting plate 3 401.

A plurality of vacuum suction cups 408 are provided and are vertically connected to the flip bar 407 upwards.

[0039] The actual application of this punching die for automobile door guide rails includes the following working processes:

[0040] Step 1: Stack two metal sheets 50 together and vertically insert them between the left and right positioning bars 307. The positioning bars 307 on both sides temporarily position the metal sheets 50 in the left and right directions, and the clamping bars 309 on both sides temporarily clamp the metal sheets 50 in the front and back directions.

[0041] Step 2: The piston rod of the hydraulic cylinder 3 402 is extended and drives the flip bar 407 to flip upward 90 degrees, so that the front and rear rows of vacuum suction cups 408 are correspondingly adsorbed to the sides of the front and rear metal sheets 50. Then, the piston rod of the hydraulic cylinder 3 402 is retracted and drives the flip bar 407 to flip downward 90 degrees, so that the front and rear rows of vacuum suction cups 408 and the two metal sheets 50 adsorbed thereon are automatically installed into the positioning grooves 202a of the front and rear lower modules 202. It should be noted that when flipping downward, the positioning bar 307 and the clamping bar 309 that are magnetically bonded together need to be stretched open by the ends of the metal sheets 50 first.

[0042] Step 3: The piston rod of the second hydraulic cylinder 302 contracts and drives the positioning bar 307 and the clamping bar 309 to turn upward 90 degrees, so that the clamping bar 309 is reattached under the dual effects of gravity and magnetic force;

[0043] Step 4: The piston rod of hydraulic cylinder 1 204 extends to drive the first upper module 206 and the second upper module 207 to penetrate downward through the metal sheet 50 and correspondingly insert into the first forming groove 202b and the second forming groove 202c of the lower module 202, thereby punching out the first process groove 50a and the second process groove 50b at the corresponding ends of the metal sheet 50. Then, the piston rod of hydraulic cylinder 1 204 contracts to drive the first upper module 206 and the second upper module 207 to move upward and return to the initial position;

[0044] Step 5: The piston rod of hydraulic cylinder 3 402 extends to drive the flipping bar 407 to flip upward by 90 degrees, so that the vacuum suction cups 408 in the front and rear rows stack the two adsorbed metal sheets 50 together again. Then, the negative pressure effect of the vacuum suction cups 408 is interrupted, and the two metal sheets 50 are automatically unloaded under the action of gravity through the long strip-shaped avoidance groove 10a. Next, the piston rod of hydraulic cylinder 3 402 contracts to drive the flipping bar 407 to flip downward by 90 degrees and return to the initial position;

[0045] Step 7: The piston rod of hydraulic cylinder 2 302 extends to drive the positioning bar 307 and the clamping bar 309 to flip downward by 90 degrees and return to the initial position.

[0046] Therefore, the above-disclosed implementation schemes are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or equivalent to the present invention are encompassed by the present invention.
