Description

TECHNICAL FIELD

[0001] The present application relates to a metal pressing die, in particular to a metal pressing die for automobile part processing, and belongs to the technical field of automobile part processing. BACKGROUND

[0002] In automobile part production, U-bending stamping is a common sheet metal forming process, mainly used for processing sheet metal into structural members with U-shaped cross section, and in the U-bending stamping process, the help of a stamping die is needed to complete it. In order to avoid the sheet metal being stuck on the punch after stamping, the prior art usually fixes metal blocking plates symmetrically on the top of the concave die to automatically drop the product when the punch resets.

[0003] However, this structure has obvious defects: when taking out the material, since the metal blocking plate is located on the top of the concave die, the formed sheet part needs to be manually pulled out from the end of the concave die, not only the taking operation is cumbersome, but also there is a great safety hazard when the hand is inserted into the die to take out the material; when loading, the existence of the metal blocking plate limits the operation mode, and only horizontal insertion can be used for loading, not only the loading process is inconvenient, but also it is difficult to ensure the accuracy of the loading position, the position adjustment is also very cumbersome, and the overall practicability is low.

[0004] Therefore, a metal pressing die for automobile part processing is designed to optimize the above problems. SUMMARY

[0005] The main objective of this invention is to provide a metal pressing mold for processing automotive parts. It features symmetrically arranged horizontal conveyor belts on both sides of the rear end of the die, with a cross plate positioned between the two sets of horizontal conveyor belts. A pushing component is located at the top of the cross plate. This, combined with a reciprocating rotation mechanism consisting of a mounting block, gears, a first pulley, a connecting shaft, a second pulley, a belt, and a rack, allows for automatic control of the horizontal movement of the pushing component during mold opening, horizontally ejecting the molded part from the die. This eliminates the need for manual hand insertion into the die, completely avoiding the safety hazards associated with hand entry. It also significantly simplifies material handling, improves processing efficiency, and adapts to mass production needs. An angle steel and support rod are installed at the rear end of the die and at the top of the horizontal conveyor belts. The material storage mechanism, consisting of a front guard plate, a first through-hole, a rear baffle, a second through-hole, a connecting rod, and a slot, allows for stacking and storing sheet metal during use. Additionally, a pusher consisting of an L-shaped base, an L-shaped push plate, and a second spring automatically performs feeding operations when the pusher moves on a horizontal conveyor belt. This breaks away from the traditional single horizontal insertion feeding method, making feeding more flexible and convenient. By symmetrically arranging vertical plates and guide grooves on both sides of the top of the upper mold base, and combining them with a limiting mechanism consisting of an L-shaped sliding plate at the front of the die, a third spring, and a sliding rod, the L-shaped sliding plate is inserted into the inner end of the die when the die is about to be fully opened and the sheet metal feeding is complete.

[0041] To make the person skilled in the art more clearly and explicitly understand the technical solutions of the present application, the present application will be further described in detail below in combination with embodiments and drawings, but the embodiments of the present application are not limited thereto.

[0042] Example 1: as Figures 1-9The embodiment shown provides a metal pressing die for automobile part processing, which comprises a lower die seat 1 and an upper die seat 2, the top of the lower die seat 1 is provided with a female die 101, the top of the female die 101 is vertically slidably provided with a top block 102, the bottom end of the top block 102 and the bottom of the female die 101 are provided with a first spring 103, the two sides of the top of the female die 101 are symmetrically provided with metal baffle plates 104, the bottom of the upper die seat 2 is provided with a male die 201 matched with the female die 101;

[0043] The two sides of the rear end of the female die 101 are symmetrically provided with horizontal conveying belts 3, a horizontal plate 4 is fixed between the two groups of horizontal conveying belts 3, and the middle position of the top of the horizontal plate 4 is provided with a pushing piece 5 for horizontally pushing the formed material out;

[0044] The end of the upper die seat 2 and the female die 101 are provided with a reciprocating rotating mechanism 6, which is in transmission connection between the reciprocating rotating mechanism 6 and the horizontal conveying belt 3, so as to control the forward and backward rotation of the horizontal conveying belt 3;

[0045] The rear end of the female die 101 and the top of the horizontal conveying belt 3 are provided with a material storage mechanism 7 for storing and moving the plate material by the pushing piece 5 to automatically feed;

[0046] The end of the female die 101 is provided with a limiting mechanism 8 matched with the upper die seat 2, which is used for limiting the front end when feeding the plate material.

[0047] The total working principle is as follows: in the initial state, the upper die seat 2 is in the raised position, the male die 201 is separated from the female die 101, the top block 102 is parallel to the top of the female die 101 under the elastic force of the first spring 103, the plate material stacked in the material storage mechanism 7 is located above the horizontal conveying belt 3, there is a certain gap between the bottommost plate material in the material storage mechanism 7 and the horizontal conveying belt 3, the limiting mechanism 8 limits the front end of the female die 101, and the horizontal plate 4 is attached to the rear end of the female die 101;

[0048] When stamping, the upper die seat 2 moves downward, the male die 201 gradually enters the female die 101, in this process, the reciprocating rotating mechanism 6 controls the rotation of the horizontal conveying belt 3, drives the pushing piece 5 to move away from the female die 101, and the pushing piece 5 passes through the bottom of the material storage mechanism 7 without moving the plate material, when the male die 201 and the female die 101 cooperate to press and form the plate material, the top block 102 is pressed into the female die 101, and the first spring 103 is compressed;

[0049] In the mold opening stage, the upper die holder 2 moves upward, the male die 201 is separated from the female die 101, the first spring 103 controls the reset of the top block 102, and under the blockage of the metal baffle 104, the formed material falls onto the top block 102. With the continuous upward movement of the upper die holder 2, the horizontal conveying belt 3 is driven in reverse by the reciprocating rotating mechanism 6, the pushing piece 5 is moved towards the female die 101, and the bottom plate of the material storage mechanism 7 is pushed, and the plate enters the female die 101 to push out the formed material. In the early stage of the formed material being pushed out, the limiting mechanism 8 does not play an intercepting role, when the formed material is about to be completely pushed out, and the plate is about to reach the front end of the female die 101, at this time, the limiting mechanism 8 will intercept the plate at the front end of the female die 101, avoiding the excessive movement of the plate, and ensuring the accuracy of the feeding position.

[0050] In the following, the scheme in embodiment 1 is further introduced in combination with a specific working mode, and details are described below.

[0051] In this embodiment, the reciprocating rotating mechanism 6 includes a mounting block 601, a gear 602, a first pulley 603, a connecting shaft 604, a second pulley 605, a belt 606 and a rack 607. The mounting block 601 is symmetrically installed on both sides of the end of the female die 101, and is located above the horizontal conveying belt 3. The outer side of the mounting block 601 is rotatably installed with the gear 602, and the inner side of the mounting block 601 is rotatably installed with the first pulley 603. The gear 602 and the first pulley 603 on the mounting block 601 are connected by a connecting rod. The connecting shaft 604 is installed between the rotating rollers on the two groups of horizontal conveying belts 3, and the second pulley 605 is provided at both ends of the connecting shaft 604. The first pulley 603 and the second pulley 605 are provided with the belt 606, and the rack 607 is vertically provided at the end of the upper die holder 2 and is engaged with the gear 602.

[0052] Partial working principle: when the upper die holder 2 moves up and down, the rack 607 at the end thereof moves synchronously, is engaged with the gear 602 on the outer side of the mounting block 601, drives the gear 602 to rotate, drives the first pulley 603 on the inner side of the mounting block 601 to rotate synchronously through the connecting rod, drives the second pulley 605 at both ends of the connecting shaft 604 to rotate through the belt 606, and then makes the horizontal conveying belt 3 reverse with the connecting shaft 604. When the upper die holder 2 moves downward for stamping, the rack 607 drives the gear 602 to rotate forward, the horizontal conveying belt 3 drives the pushing piece 5 to retreat, and when the upper die holder 2 moves upward for mold opening, the rack 607 drives the gear 602 to rotate reversely, and the horizontal conveying belt 3 drives the pushing piece 5 to advance.

[0053] In the embodiment, the material storage mechanism 7 comprises angle steels 701, supporting rods 702, front guards 703, first through holes 704, rear stops 705 and second through holes 706. The angle steels 701 are symmetrically arranged at the rear end of the concave die 101 and on the top of the horizontal conveying belt 3. The supporting rods 702 are fixed between the lower die seat 1 and the angle steels 701. The front guards 703 are fixed between the two groups of angle steels 701, and the outer end surface of the front guard 703 is attached to the end surface of the concave die 101. The bottom of the front guard 703 and the inner bottom of the angle steel 701 are provided with the first through hole 704, and the first through hole 704 is the same as the thickness of the plate. The ends of the two groups of angle steels 701 away from the front guard 703 are vertically provided with the rear stop 705, and the bottom end of the rear stop 705 is provided with the second through hole 706 for the pusher 5 to pass through.

[0054] Partial working principle: the angle steel 701 is fixed on the lower die seat 1 through the supporting rod 702 to form a plate storage space. The plate is stacked inside the angle steel 701. The front guard 703 limits the front end position of the plate, and the rear stop 705 limits the rear end position of the plate. The first through hole 704 between the bottom of the front guard 703 and the inner bottom of the angle steel 701 is consistent with the thickness of the plate, allowing only the bottommost plate to pass through. When the pusher 5 advances with the horizontal conveying belt 3, it passes through the second through hole 706 at the bottom end of the rear stop 705, pushes the bottommost plate out of the first through hole 704 to the concave die 101, and the upper plate falls under the action of gravity to replenish the bottommost position and wait for the next push.

[0055] In the embodiment, the bottom end of the rear stop 705 is rotationally connected with the angle steel 701, and the connecting rods 707 are installed on both sides of the rear stop 705.

[0056] Partial working principle: the bottom end of the rear stop 705 is rotationally connected with the angle steel 701, which can be flipped outward to open, facilitating the addition of plates to the material storage mechanism 7. After the addition is completed, the rear stop 705 is rotated to attach to the rear end of the plate. The connecting rods 707 on both sides are clamped into the clamping grooves 708 on the side edges of the front guard 703 to fix the rear stop 705 and prevent the plate from retreating. The connecting rod 707 is L-shaped.

[0057] In the embodiment, the pusher 5 comprises an L-shaped base 501, an L-shaped push plate 502 and a second spring 503. The L-shaped base 501 is fixedly installed on the top of the cross plate 4. The L-shaped push plate 502 is rotationally installed on the inner top of the L-shaped base 501. The second spring 503 is installed between the inner side of the L-shaped push plate 502 and the L-shaped base 501.

[0058] Local working principle: L-shaped base 501 is fixed on the horizontal plate 4 and moves synchronously with the horizontal conveying belt 3, the L-shaped push plate 502 is installed on the top of the L-shaped base 501 through a rotating shaft, the second spring 503 between the inner side of the L-shaped push plate 502 and the L-shaped base 501 is in a natural state, the top end of the L-shaped push plate 502 extends out of the L-shaped base 501, when the pusher 5 advances, the top end of the L-shaped push plate 502 pushes the bottommost plate in the material storage mechanism 7 into the die 101, when the pusher 5 retreats, the L-shaped push plate 502 is pressed after being in contact with the plate, rotates inward around the rotating shaft and compresses the second spring 503, and passes below the plate to avoid driving the plate to retreat, after retreating to the initial position, the second spring 503 resets, and the L-shaped push plate 502 returns to the initial state.

[0059] In this embodiment, the corner of the top end of the L-shaped push plate 502 is arc-shaped, and the corner is coated with a wear-resistant coating.

[0060] Local working principle: The corner of the top end of the L-shaped push plate 502 is arc-shaped and coated with a wear-resistant coating, which can reduce the frictional resistance when pushing the plate, avoid scratching the plate, and prolong the service life of the L-shaped push plate 502.

[0061] In this embodiment, the limiting mechanism 8 includes an L-shaped sliding plate 801, a third spring 802, a vertical plate 804 and a guide groove 805, the L-shaped sliding plate 801 is symmetrically and slidably arranged at the front end of the two groups of metal blocking plates 104, the third spring 802 is arranged between the outer end of the L-shaped sliding plate 801 and the side edge of the metal blocking plate 104, the vertical plate 804 is vertically fixed on the two sides of the upper die seat 2 and located between the L-shaped sliding plate 801 and the side edge of the die 101, the outer side of the bottom end of the vertical plate 804 is provided with the guide groove 805, and the top end of the guide groove 805 is inclined.

[0063] In this embodiment, when the vertical plate 804 slides, the outer side is in contact with the inner side of the L-shaped sliding plate 801, and the depth of the guide groove 805 is equal to the length of the end of the L-shaped sliding plate 801 inserted into the inside of the die 101.

[0064] Local working principle: when the vertical plate 804 slides, the outer side is attached to the inner side of the L-shaped slide plate 801, ensuring that the L-shaped slide plate 801 moves accurately with the vertical plate 804. The depth of the guide groove 805 is equal to the length of the L-shaped slide plate 801 inserted into the recess die 101, ensuring that the L-shaped slide plate 801 can be completely reset and inserted into the recess die 101 when the mold is opened, achieving reliable limiting.

[0065] In this embodiment, the front end of the metal baffle 104 is provided with a strip-shaped groove in the width direction, and the L-shaped slide plate 801 is slidingly arranged inside the strip-shaped groove.

[0066] Local working principle: the strip-shaped groove at the front end of the metal baffle 104 provides a sliding track for the L-shaped slide plate 801, ensuring that the L-shaped slide plate 801 moves stably in the horizontal direction and avoids deviation affecting the limiting effect.

[0067] In this embodiment, the side edges of the two groups of metal baffles 104 are fixed with slide rods 803, which pass through the inside of the third spring 802 and are slidingly connected with the L-shaped slide plate 801.

[0068] Local working principle: the slide rod 803 is fixed on the side edge of the metal baffle 104, passes through the inside of the third spring 802 and is slidingly connected with the L-shaped slide plate 801, which not only guides the third spring 802 to prevent it from twisting when compressed / reset, but also helps the L-shaped slide plate 801 to maintain a horizontal sliding track.
