Description

Technical Field

[0001] This utility model relates to a stamping machine, specifically a continuous feeding stamping machine. Background Technology

[0002] A stamping press is a mechanical device that uses pressure to plastically deform or separate metallic or non-metallic materials. It is widely used in industries such as automotive, electronics, home appliances, and aerospace. Its core principle is to generate pressure through mechanical, hydraulic, or servo drive systems, which, in conjunction with dies, complete processes such as punching, bending, stretching, and forming.

[0003] When processing coiled materials, stamping presses often employ continuous feeding to reduce production costs. Through cooperation with progressive dies, the material can be continuously stamped in stages to obtain the finished product. Common continuous feeding methods often utilize roller feeders; the coiled material is fixed to a release structure and guided between rollers. The rollers' rotation propels the coiled material within the progressive die. Simultaneously, the release structure rotates to release the coiled material. Common methods for driving the release structure include roller drive and separate drive.

[0004] When the release structure is driven by rolling, the resistance to the roller's movement of the coil material on the progressive die is very high because the roller's rotation guides the coil material to rotate. When the resistance reaches a certain level, slippage occurs, which is detrimental to the orderly stamping process. However, when the release structure is driven independently, the initial diameter of the coil material is relatively large, and the initial angular velocity of the coil material driven by the release structure is very small. Therefore, the linear velocity of the coil material rotation (release speed) can match the roller's rotation speed, allowing the coil material to move smoothly on the progressive die. But as the coil material is consumed, its diameter decreases, resulting in a decreasing linear velocity and a widening gap between the roller's rotation speed and the release speed. At this point, the resistance to the roller's movement of the coil material increases, and when the resistance reaches a certain level, slippage occurs, disrupting the coil material's step distance on the progressive die and hindering the orderly stamping process.

[0010] The main rotating shaft drives the material rack to rotate via a transmission component;

[0011] It also includes an adjusting component disposed on the bracket, the adjusting component being able to change the transmission ratio of the transmission component to increase the rotational speed of the material rack.

[0045] 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.

[0046] Please see Figures 1-7 As an embodiment of the present utility model, the continuous feeding stamping machine includes a stamping module 1 and a bracket 2 fixedly installed on one side of the stamping module 1;

[0047] It also includes a material rack 3 rotatably mounted on one end of the bracket 2; a lower pressure roller 4 is rotatably mounted on the other end of the bracket 2;

[0048] A motor 8 is fixedly mounted on the bracket 2; a main shaft 9 is fixedly mounted on the output end of the motor 8; the main shaft 9 is connected to the lower pressure roller 4 by a belt.

[0049] The main rotating shaft 9 drives the material rack 3 to rotate via a transmission component;

[0050] It also includes an adjusting component, which is disposed on the bracket 2. The adjusting component can change the transmission ratio of the transmission component to increase the rotational speed of the material rack 3.

[0051] In this embodiment, the material rack 3 is used to fix the roll material, and the material rack 3 can release the rolled material when it is rotated.

[0052] When the lower pressure roller 4 rotates, it can guide the coil material released by the material rack 3 to move towards the stamping module 1.

[0053] The stamping module 1 can provide stamping force, and the progressive dies on the stamping module 1 cooperate with each other to stamp the coil into shape.

[0054] When the motor 8 can operate intermittently, it can drive the main shaft 9 to rotate intermittently, thereby driving the lower pressure roller 4 to rotate intermittently via the belt, and simultaneously driving the material rack 3 to rotate intermittently via the transmission components; thus, the roll material is released intermittently and the roll material is guided to move intermittently on the progressive die.

[0055] By gradually increasing the transmission ratio of the transmission components through the adjusting components, the transmission ratio between the main rotating shaft 9 and the material rack 3 is increased, thereby gradually increasing the rotational speed of the material rack 3 to compensate for the roll release speed.

[0056] By cooperating with the adjusting component and the transmission component, the adjusting component increases the transmission ratio of the transmission component during the release of the roll material, thereby compensating for the release speed of the roll material. This prevents deviations in the subsequent stamping position caused by the gradual decrease in the release speed of the roll material as it is consumed, thus improving the stability of the feeding process and enhancing the stamping accuracy.

[0057] As a further embodiment of this utility model, the transmission component includes a release shaft 10 fixedly installed on the material rack 3; a first half pulley 901 symmetrically arranged is slidably fitted on the main shaft 9; a second half pulley 1001 symmetrically arranged is slidably fitted on the release shaft 10; and multiple sets of first half pulleys 901 and second half pulleys 1001 are connected by a release belt 11.

[0058] In this embodiment, when the main shaft 9 rotates, it drives multiple sets of first half pulleys 901 to rotate synchronously, and drives the second half pulleys 1001 to rotate through the release belt 11, thereby driving the release shaft 10 to rotate and driving the material rack 3 to rotate to release the roll material.

[0059] There is a gap between the first half pulley 901 and there is also a gap between the second half pulley 1001.

[0060] In the initial state, the distance between the first half pulleys 901 is relatively large, while the distance between the second half pulleys 1001 is relatively small. Therefore, the release belt 11 is closer to the axis of the main shaft 9, while the release belt 11 is farther from the axis of the release shaft 10. At this time, the transmission ratio between the main shaft 9 and the release shaft 10 is relatively small, so the rotational speed of the release shaft 10 is relatively small.

[0061] The initial radius of the roll material is relatively large, but it gradually decreases as it is released.

[0062] As the stamping process proceeds, the distance between the first half pulleys 901 gradually decreases, while the distance between the second half pulleys 1001 gradually increases. This causes the release belt 11 to slide on the first half pulleys 901 and the second half pulleys 1001, gradually moving away from the axis of the main shaft 9 and gradually moving closer to the axis of the release shaft 10. This results in a gradual increase in the transmission ratio between the main shaft 9 and the release shaft 10, thereby increasing the rotational speed of the release shaft 10.

[0063] Compared to the initial state, the increase in the angular velocity of the release shaft 10 and the decrease in the radius of the coil material result in a relatively balanced linear velocity of the coil material release. This avoids deviations in the subsequent stamping position due to the gradual decrease in the release speed of the coil material as it is consumed, thereby improving the stability of the feeding process and enhancing the stamping accuracy.

[0064] As a further embodiment of this utility model, the adjusting component includes an adjusting shaft 12 rotatably mounted on the bracket 2. Multiple sets of contraction sleeves 13 and expansion sleeves 14 are sleeved on the adjusting shaft 12. Multiple sets of symmetrically arranged first spiral grooves 1201 and multiple sets of symmetrically arranged second spiral grooves 1202 are provided on the adjusting shaft 12. A first protruding post 1301 is fixedly mounted on the contraction sleeve 13 and slidably engages with the first spiral groove 1201. A second protruding post 1401 is fixedly mounted on the expansion sleeve 14 and slidably engages with the second spiral groove 1202. The contraction sleeve 13 is rotatably connected to the first half-pulley 901, and the expansion sleeve 14 is rotatably connected to the second half-pulley 1001.

[0065] In this embodiment, the main rotating shaft 9 and the adjusting rotating shaft 12 are connected by a belt, so the adjusting rotating shaft 12 will also rotate when the main rotating shaft 9 rotates; and the transmission ratio between the main rotating shaft 9 and the adjusting rotating shaft 12 is very small, so the rotational speed of the adjusting rotating shaft 12 is slower than that of the main rotating shaft 9.

[0066] The rotating adjusting shaft 12 drives the first spiral groove 1201 and the second spiral groove 1202 to rotate, causing the first protruding post 1301 to slide in the first spiral groove 1201 and the second protruding post 1401 to slide in the second spiral groove 1202. Under the squeezing action of the first spiral groove 1201, the first protruding post 1301 drives the shrinking sleeve 13 to move closer together, thereby driving the first half pulley 901 to move closer together. Under the squeezing action of the second spiral groove 1202, the second protruding post 1401 drives the expanding sleeve 14 to move away from each other, thereby driving the second half pulley 1001 to move away from each other. This gradually increases the transmission ratio between the main rotating shaft 9 and the release rotating shaft 10, so as to avoid the subsequent stamping position deviation caused by the gradual decrease in the release speed of the coil material as the coil material is consumed, thereby improving the stability of feeding and improving the stamping accuracy.

[0067] As a further embodiment of this utility model, a slider 6 is slidably fitted on the bracket 2; a clamping spring 7 is provided on the bracket 2; the two ends of the clamping spring 7 respectively abut against the slider 6 and the bracket 2, and an upper pressure roller 5 that cooperates with the lower pressure roller 4 is rotatably mounted on the slider 6.

[0068] In this embodiment, when the roll passes through the upper pressure roller 5 and the lower pressure roller 4, it will squeeze the upper pressure roller 5 and the lower pressure roller 4, thereby driving the slider 6 away from the lower pressure roller 4 to compress the clamping spring 7, thereby increasing the elastic force.

[0069] The elastic force of the clamping spring 7 increases the squeezing force of the lower pressure roller 4 and the upper pressure roller 5 on the coil material, which can effectively increase the friction between the lower pressure roller 4 and the coil material. When the lower pressure roller 4 rotates, it can drive the coil material to move towards the stamping module 1. This can effectively avoid slippage and thus improve stamping accuracy.

[0070] As a further embodiment of this utility model, the adjusting shaft 12 is provided with a third spiral groove 1203; a reset sleeve 15 is slidably installed on the bracket 2; a third protruding post 1501 that is slidably fitted into the third spiral groove 1203 is fixedly installed inside the reset sleeve 15; a large spring 19 is sleeved on the adjusting shaft 12; the two ends of the large spring 19 respectively abut against the reset sleeve 15 and the bracket 2.

[0071] In this embodiment, as the adjusting shaft 12 rotates, the third spiral groove 1203 also rotates synchronously, thereby driving the third protruding post 1501 to slide in the third spiral groove 1203, so as to drive the reset sleeve 15 to gradually approach the bracket 2 and compress the large spring 19.

[0072] As a set of rolls of material is continuously consumed, the reset sleeve 15 gets closer and closer to the bracket 2, and the compression of the large spring 19 also increases. When the rolls of material are exhausted, the elastic force of the large spring 19 can drive the reset sleeve 15 away from the bracket 2. Thus, through the sliding engagement of the third protruding post 1501 and the third spiral groove 1203, the adjusting shaft 12 can be driven to rotate, thereby driving the first protruding post 1301 and the second protruding post 1401 to reset, so as to restore the transmission ratio between the main shaft 9 and the release shaft 10, thus facilitating the processing of the next set of rolls of material.

[0073] As a further embodiment of this utility model, a fixed turntable 16 is fixedly installed at one end of the adjusting shaft 12; multiple sets of first tooth blocks 1601 are fixedly installed on the fixed turntable 16; a locking turntable 17 is slidably installed on the bracket 2; multiple sets of second tooth blocks 1701 that can mesh with the first tooth blocks 1601 are fixedly installed on the locking turntable 17; a return spring 18 is provided on the bracket 2; the two ends of the return spring 18 respectively abut against the locking turntable 17 and the bracket 2.

[0074] As a further embodiment of this utility model, both the first tooth block 1601 and the second tooth block 1701 are provided with a flat surface and an inclined surface.

[0075] In this embodiment, during the processing of a set of roll materials, the main rotating shaft 9 will drive the release rotating shaft 10 and the adjustment rotating shaft 12 to rotate intermittently in the forward direction to cooperate with the stamping module 1 to stamp the roll material.

[0076] When the release shaft 10 rotates, the roll material moves forward one step under the drive of the lower pressure roller 4; at this time, the adjusting shaft 12 also rotates to compensate for the release speed of the roll material, and drives the fixed turntable 16 to rotate, thereby driving the first tooth block 1601 to rotate. During this process, the inclined surface of the first tooth block 1601 and the inclined surface of the second tooth block 1701 press against each other and cooperate, and the second tooth block 1701 pushes the locking turntable 17 away from the fixed turntable 16 and compresses the return spring 18 so that the adjusting shaft 12 can rotate.

[0077] When the release shaft 10 stops rotating, the stamping module 1 performs the stamping action. At this time, the adjusting shaft 12 does not rotate, and the flat surfaces of the first tooth block 1601 and the second tooth block 1701 abut against each other to limit the adjusting shaft 12 from rotating in the opposite direction due to the elastic force of the large spring 19, thereby ensuring the orderly progress of processing. After a set of coils is processed, external force can be applied to disengage the first tooth block 1601 and the second tooth block 1701 to complete the reset, so as to facilitate the processing of the next set of coils.

[0078] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
