Description

Technical Field

[0001] This utility model relates to the field of mold stamping technology, and more specifically, to an automatic feeding mechanism for stamping dies. Background Technology

[0002] Stamping is a processing method that uses a press and dies to apply external force to a blank, causing it to undergo plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. It is applied to almost every sector of the national economy. The blanks used in stamping production mainly include strips, coils, and sheets. After being leveled, these blanks need to be correctly fed into the dies to ensure smooth stamping production. Traditionally, stamping production relies heavily on manual feeding, which suffers from low production efficiency, high labor intensity, low safety, and susceptibility to human error in the production process and workpiece quality, making it difficult to meet the demands of modern, rapidly developing stamping production. While automatic feeding devices can effectively solve these problems, these devices are often located separately from the stamping dies, which increases production costs.

[0003] To address the aforementioned problems, there is an urgent need for an automatic feeding mechanism for stamping dies. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic feeding mechanism for stamping dies to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, an automatic feeding mechanism for stamping dies is provided, including feeding tables arranged in a front-to-back configuration and a feeding mechanism disposed between the feeding tables. The feeding tables include a base plate and an upper cover plate disposed on top of the base plate, wherein the height between the base plate and the upper cover plate is adjusted by bolts, and a motor is disposed inside the base plate of the front feeding table.

[0006] The feeding mechanism includes a base and a pressure plate that can move up and down on the top of the base. A first spring and a telescopic rod are provided between the base and the pressure plate. An "L"-shaped channel is opened inside the base. A round tube is also installed on the side of the front base plate. The other end of the round tube is inserted into the channel. A pressure block is provided on the top of the pressure plate. A cable is attached to the bottom of the pressure block. The other end of the cable passes through the pressure plate, the telescopic rod and the channel and exits from the side of the base. Then it passes through the round tube and connects to the motor.

[0007] Furthermore, a winch is installed on the output shaft of the motor, and the cable is connected to the winch of the motor. There are at least two channels and cables, and at least two winches are provided on the output shaft of the motor.

[0008] Furthermore, a second spring is provided on the outside of the circular tube. The two ends of the second spring are respectively connected to the front base plate and the base. Both the first spring and the second spring are compression springs, and the elastic coefficient of the first spring is smaller than that of the second spring.

[0009] Furthermore, a fixed pulley is provided inside the channel, through which the cable passes. The cable's movement through the fixed pulley reduces friction, and the fixed pulley also helps stabilize the cable's trajectory.

[0010] Furthermore, the top of the base is provided with a recessed groove for installing the first spring and the telescopic rod, wherein the first spring is sleeved on the outside of the telescopic rod. By placing the first spring and the telescopic rod in the recessed groove, there are no other components between them that would obstruct the downward pressing of the pressure plate when it is pressed down.

[0011] Furthermore, the top of the pressure plate is provided with a locking block for fixing the pressure block, which can prevent the pressure block from moving.

[0012] Furthermore, one end of the channel is located on the upper surface of the base, and the other end of the channel is located on the side of the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The feeding mechanism uses a motor to wind a cable, enabling it to perform both pressing and feeding functions. During this process, the feeding mechanism does not rub against the conveyor belt, thus avoiding wear on the conveyor belt.

[0015] The entire pressing and feeding process is powered entirely by electric motors. Compared with traditional feeding mechanisms, this reduces the power required, saves resources, and also increases the integration of the equipment.

[0016] Compared with traditional manual feeding, it improves production efficiency, reduces labor intensity, enhances safety, and avoids problems such as the production process and workpiece quality being easily affected by human factors. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0024] Please see Figures 1-3 As shown, an automatic feeding mechanism for stamping dies is provided, including a feeding platform 1 arranged in front and behind and a feeding mechanism 2 arranged between the feeding platforms 1. The feeding platform 1 includes a base plate 101 and an upper cover plate 102 arranged on top of the base plate 101. The height between the base plate 101 and the upper cover plate 102 is adjusted by bolts 103. A motor 3 is installed inside the base plate 101 of the front feeding platform 1.

[0025] The feeding mechanism 2 includes a base 201 and a pressure plate 202 that can move up and down on the top of the base 201. A first spring 203 and a telescopic rod 204 are provided between the base 201 and the pressure plate 202. An "L"-shaped channel 207 is opened inside the base 201. A round tube 4 is also installed on the side of the front base plate 101. The other end of the round tube 4 is inserted into the channel 207. A pressure block 205 is provided on the top of the pressure plate 202. A pull cable 206 is attached to the bottom of the pressure block 205. The other end of the pull cable 206 passes through the pressure plate 202, the telescopic rod 204 and the channel 207 and comes out from the side of the base 201. Then it passes through the round tube 4 and connects to the motor 3.

[0026] In actual use, as the motor 3 rotates, the motor 3 drives the cable 206, and the end of the cable 206 is tied to the pressure block 205. Then the pressure block 205 presses down the pressure plate 202. At this time, the pressure plate 202 tightly presses the strip onto the surface of the base 201. As the motor 3 continues to rotate, the pressure plate 202 can no longer press down. At this time, under the action of the cable 206, the entire base 201 begins to squeeze the second spring 5 and move along the direction of the round tube 4. During this movement, the entire feeding mechanism 2 moves the strip a corresponding distance, and then the stamping die performs the stamping.

[0027] Then the motor 3 stops working. At this time, the strip is pressed down by the stamping die, making it unable to move. Meanwhile, the feeding mechanism 2 is still pressing down on the strip, forming a whole with it. After the motor 3 stops working, the pressure plate 202 releases its pressing action on the strip under the action of the first spring 203. Then, under the action of the second spring 5, the feeding mechanism 2 begins to reset.

[0028] Please refer to Figure 1 As shown:

[0029] A winch is installed on the output shaft of the motor 3, and the cable 206 is connected to the winch of the motor 3. There are at least two channels 207 and cables 206, and at least two winches are provided on the output shaft of the motor 3.

[0030] A second spring 5 is provided on the outside of the circular tube 4. The two ends of the second spring 5 are respectively connected to the front base plate 101 and the base 201. The first spring 203 and the second spring 5 are both compression springs. The elastic coefficient of the first spring 203 is smaller than that of the second spring 5. Since the elastic coefficient of the first spring 203 is smaller, the first spring 203 will be compressed first when the motor 3 is working.

[0031] from Figure 1 It can also be seen that a fixed pulley 6 is provided inside the channel 207, and the cable 206 passes through the fixed pulley 6. The cable 206 can reduce friction when passing through the fixed pulley 6, and the presence of the fixed pulley 6 can keep the cable 206 close to the central axis of the circular tube 4, reducing the wear of the cable 206.

[0032] exist Figure 1 It can also be seen that a recessed groove 7 for installing the first spring 203 and the telescopic rod 204 is provided on the top of the base 201. The first spring 203 is sleeved on the outside of the telescopic rod 204. By setting the first spring 203 and the telescopic rod 204 in the recessed groove 7, there will be no other components between the two to obstruct the downward pressing of the pressure plate 202 when it is pressed down.

[0033] It should be noted that, in order to prevent the pressure block 205 from moving, two locking blocks are provided on the top of the pressure plate 202 to limit the offset of the pressure block 205. Similarly, in order to prevent the material strip from shifting, corresponding limiting devices can also be provided on the top of the base 201 and the bottom plate 101.

[0034] Work process:

[0035] like Figure 1 As shown, the conveyor belt passes through the feeding table 1 and the feeding mechanism 2. At this time, the pressure plate 202 on the feeding mechanism 2 does not press the conveyor belt. After the motor 3 starts working, because the elastic coefficient of the first spring 203 is less than that of the second spring 5, the first spring 203 will be compressed first, so that the pressure plate 202 presses tightly against the surface of the conveyor belt, thus fixing the conveyor belt and the feeding mechanism 2 together. As the motor 3 continues to work, the second spring 5 will also be compressed, and the feeding mechanism 2 will move along the direction of the circular tube 4 with the conveyor belt to complete the feeding work. The working state at this time is as follows. Figure 2 As shown;

[0036] When the feeding operation is completed, the stamping die also begins to stamp the strip. At this time, the strip is pressed and cannot move, and the feeding mechanism 2 cannot move either. The movement of the pressure plate 202 is not affected by the strip. Under the action of the first spring 203, it begins to reset. After the pressure plate 202 resets, the feeding mechanism 2 is also not affected by the strip. So under the action of the second spring 5, it begins to reset. Thus, the feeding mechanism 2 completes one complete feeding operation.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
