Description

Technical Field

[0001] This utility model belongs to the technical field of stamping feeders, specifically an optimized structure for pneumatic release of a stamping feeder. Background Technology

[0002] A stamping roller feeder is a widely used automated device in stamping production, primarily used to accurately feed materials such as metal strips onto the stamping processing equipment. The working principle of the stamping roller feeder is relatively simple, relying mainly on the output shaft of the stamping press as a power source to drive the feeding rollers for continuous feeding. When the material is placed above the feeder, the rollers begin to rotate. Through the friction between the rollers and the material, the material is automatically pushed downwards and conveyed to the target position below.

[0003] Traditional pneumatically driven feeders can only release the upper rollers from the end to the bottom of the cylinder, with no adjustable stroke. This leads to excessive cylinder stroke and inaccurate control, making it impossible to adjust the upper roller clearance. Furthermore, it consumes a lot of air. The excessive stroke also results in high impact force when the upper rollers clamp, reducing the machine's lifespan and causing indentations on softer materials. To address these issues, we provide an optimized pneumatic release structure for stamping feeders. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an optimized structure for the pneumatic release of a stamping feeder. It features the advantage of allowing arbitrary adjustment of the cylinder stroke, resulting in shorter cylinder-driven roller time and reduced air consumption, thus solving the problems of current pneumatically driven feeders mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an optimized structure for pneumatic release of a stamping feeder, comprising a bracket, a cylinder fixedly mounted on the top of the bracket, a support plate provided in the inner cavity of the bracket, a fixed seat provided on the top of the support plate, an adjusting screw movably connected between the fixed seat and the cylinder, a support frame provided at the bottom of the support plate, and rollers rotatably connected between the left and right sides of the inner wall of the support frame.

[0008] Preferably, guide rods are provided on both the left and right sides of the top of the fixed base, and the top of the guide rods penetrates the top of the inner wall of the bracket.

[0009] Preferably, the adjusting screw includes a screw rod, the top of which penetrates the top of the inner wall of the bracket and is fixedly connected to the output shaft of the cylinder, the bottom of which penetrates the top of the fixed seat and the support plate in sequence and is fixedly connected to the top of the support frame, and a nut is movably sleeved on the lower part of the outer ring of the screw rod, the bottom of which is fixedly connected to the top of the fixed seat.

[0010] Preferably, the bracket has sliding grooves on both the left and right sides, and the support frame has sliders on both the left and right sides, with the sliders slidingly engaging with the inner cavity of the sliding grooves.

[0011] Preferably, a rotating shaft is connected through the left side of the roller, and the left and right sides of the rotating shaft are respectively rotatably connected to the left and right sides of the inner wall of the support frame.

[0012] Preferably, a dial is fixedly sleeved on the upper part of the outer ring of the screw, and the outer ring of the dial has multiple notches evenly distributed.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. When in use, the dial can be rotated clockwise or counterclockwise by holding the notch to drive the screw clockwise or counterclockwise. At this time, due to the blocking effect of the guide rod, the nut can drive the fixed seat to move down or up. This can adjust the stroke of the cylinder and the release gap of the roller. The cylinder drives the upper roller for a shorter time and reduces air consumption. After the improvement, the cylinder stroke can be adjusted arbitrarily, the cylinder drives the roller for a shorter time, and reduces air consumption.

[0016] 2. When in use, the feeder is suitable for softer materials because the rollers are controlled by the adjusting screw to open the gap small, resulting in less impact when pressing down and no obvious indentation on the material surface, which can effectively ensure the excellent appearance of the material.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution: an optimized structure for pneumatic release of a stamping feeder, including a bracket 1, a cylinder 2 fixedly installed on the top of the bracket 1, a support plate 3 provided in the inner cavity of the bracket 1, a fixed seat 4 provided on the top of the support plate 3, an adjusting screw 5 movably connected between the fixed seat 4 and the cylinder 2, a support frame 6 provided at the bottom of the support plate 3, and rollers 7 rotatably connected between the left and right sides of the inner wall of the support frame 6.

[0025] The adjusting screw 5 includes a screw 51. The top of the screw 51 passes through the top of the inner wall of the bracket 1 and is rotatably connected to the output shaft of the cylinder 2. The bottom of the screw 51 passes through the top of the fixed seat 4 and the top of the support plate 3 in sequence and is fixedly connected to the top of the support frame 6. The lower part of the outer ring of the screw 51 is movably fitted with a nut 52. The bottom of the nut 52 is fixedly connected to the top of the fixed seat 4. When in use, if the screw 51 rotates clockwise, the nut 52 moves downward; if the screw 51 rotates counterclockwise, the nut 52 moves upward.

[0026] Furthermore, a dial 10 is fixedly sleeved on the upper part of the outer ring of the screw 51, and the outer ring of the dial 10 is evenly provided with multiple notches 101.

[0027] Furthermore, guide rods 8 are provided on both the left and right sides of the top of the fixed base 4, and the top of the guide rods 8 penetrates the top of the inner wall of the bracket 1.

[0028] In practical use, by holding notch 101 and rotating dial 10 clockwise or counterclockwise, the screw 51 can be driven to rotate clockwise or counterclockwise. At this time, due to the blocking effect of guide rod 8, nut 52 can drive fixed seat 4 to move downward or upward, thus adjusting the stroke of cylinder 2 and adjusting the release clearance of roller 7. The time for cylinder 2 to drive roller 7 is shorter and the air consumption is reduced. After the improvement, the stroke of cylinder 2 can be adjusted arbitrarily, the time for cylinder 2 to drive roller 7 is shorter, and the air consumption is reduced (for example, if the material being processed by the feeder is 1mm thick, the adjusting screw 5 can be adjusted to the corresponding position). When cylinder 2 operates, it moves within the 1mm thickness range each time. Before the modification, cylinder 2 would reach its full stroke limit at both ends. If a 10mm stroke cylinder 2 was used before the modification, the stroke of cylinder 2 would need to be 10mm. After the modification, taking a 1mm thick material as an example, the stroke of cylinder 2 is only one-tenth of that before the modification. At the same time, for softer materials, the feeder has a small opening gap controlled by the adjusting screw 5, resulting in less impact when pressing down and no obvious indentation on the material surface, which can effectively ensure the excellent appearance of the material.

[0029] Among them, the left side of the roller 7 is connected to the rotating shaft 71, and the left and right sides of the rotating shaft 71 are respectively rotatably connected to the left and right sides of the inner wall of the support frame 6.

[0030] Furthermore, the bracket 1 has sliding grooves 11 on both the left and right sides, and the support frame 6 has sliders 9 on both the left and right sides, with the sliders 9 slidingly engaged in the inner cavity of the sliding grooves 11.

[0031] During the stamping and feeding process, the cylinder 2 can drive the fixed seat 4 and the support frame 6 to move downward through the screw 51, and at the same time drive the roller 7 to move downward. During this process, the support frame 6 can be kept moving smoothly by the sliding action of the slider 9 in the slide groove 11. Meanwhile, the roller 7 can rotate in the support frame 6 through the rotating shaft 71 to transport the material downward.
