Description

Technical Field

[0001] This utility model relates to the field of punch press feeder technology, and in particular to a feeder with stable power transmission. Background Technology

[0002] A punch press feeder is a device installed at the front end (input end) of a punch press for conveying materials (sheet metal). Existing punch press feeders include a housing, a lower feed roller, an upper feed roller, and a drive mechanism. The lower feed roller is driven by the drive mechanism and works in conjunction with the upper feed roller to feed materials. Because the lower feed roller is driven by only one drive mechanism, when the material to be conveyed is heavy or requires rapid conveying, a single drive mechanism cannot meet the power requirements for conveying. Utility Model Content

[0003] The purpose of this invention is to provide a feeder with stable power transmission, so as to solve the problem that the lower feed roller of the existing punch press feeder is driven by a single drive mechanism and cannot meet the power transmission requirements.

[0004] This utility model is achieved through the following technical solution:

[0005] A feeder with stable power transmission includes a housing. The housing is equipped with a lower feed roller, an upper feed roller, a main drive mechanism, and a transmission shaft assembly. The two axial ends of the lower feed roller are respectively connected to the main drive mechanism and the transmission shaft assembly. The lower feed roller is driven by the main drive mechanism. The transmission shaft assembly has a transmission shaft rotatably connected to the housing. One end of the transmission shaft is connected to the lower feed roller, and the other end is exposed outside the housing. The end of the transmission shaft exposed outside the housing is provided with a transmission hole. The upper feed roller is located on one side of the lower feed roller and is spaced apart from the lower feed roller to form a feeding gap.

[0006] Furthermore, the housing has an insertion hole through which the lower feed roller passes, and the drive shaft assembly has a bearing, which passes through the drive shaft and is fitted into the insertion hole.

[0007] Furthermore, the axial direction of the drive shaft is defined as the front-to-back direction, the drive shaft assembly has two limiting rings, the two limiting rings are inserted on the drive shaft and cooperate to restrict the bearing from moving back and forth relative to the drive shaft, and the limiting rings are detachably fixedly connected to the housing.

[0008] Furthermore, of the two limiting rings, one limiting ring is defined as a rear limiting ring and the other limiting ring is defined as a front limiting ring. The rear limiting ring is located rearward, and the front limiting ring is located forward. The housing is provided with a front limiting hole for inserting the front limiting ring. The front limiting ring has a front stop portion that extends rearward into the insertion hole and abuts against the bearing. The drive shaft has a rear shoulder, and the rear shoulder cooperates with the front limiting ring to restrict the forward and backward movement of the bearing.

[0009] Furthermore, the lower feed roller has a mounting hole for inserting the drive shaft.

[0010] Furthermore, two hydraulic tensioning sleeves are provided on the lower feed roller, and the two hydraulic tensioning sleeves are spaced apart in the axial direction of the lower feed roller.

[0011] Furthermore, the main drive mechanism is mounted on the housing and has a main motor that is connected to the lower feed roller. The output shaft of the main motor is defined as the main output shaft, and the lower feed roller has a main mounting hole for the main output shaft to be inserted.

[0012] Furthermore, the housing is provided with a cover, which is detachably and fixedly connected to the housing to cover one end of the drive shaft exposed in the housing.

[0013] Furthermore, it also includes a secondary drive mechanism, which is detachably fixedly connected to the transmission shaft assembly via the transmission hole, and the lower feed roller is driven by the main drive mechanism and the secondary drive mechanism.

[0014] Furthermore, the auxiliary drive mechanism is mounted on the housing and has an auxiliary motor that is connected to the drive shaft. The output shaft of the auxiliary motor is defined as the auxiliary output shaft, and the auxiliary output shaft is inserted into the drive hole.

[0015] The advantage of this technical solution is that by configuring a transmission shaft assembly at the end of the lower feed roller away from the main drive mechanism, the transmission shaft assembly has a transmission shaft that is rotatably connected to the housing, the transmission shaft is connected to the lower feed roller and has a transmission hole, and the transmission hole is used for detachable fixed connection with the auxiliary drive mechanism, so that the feeder with stable power transmission can increase the driving power by adding a drive mechanism when the power is insufficient, and can remove the auxiliary drive mechanism to reduce the driving power when the power is sufficient, thus realizing single drive (driven only by the main drive mechanism) and dual drive (driven by the main drive mechanism and the auxiliary drive mechanism) of the lower feed roller, with strong driving force and flexible use.

[0026] 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.

[0027] Example: Figure 1-8As shown, the power-transmitting and stable feeder includes a housing 1 and a lower feed roller 2, an upper feed roller 3, a main drive mechanism 4, a secondary drive mechanism 5, and a transmission shaft assembly 6 mounted on the housing 1. The axial ends of the lower feed roller 2 are connected to the main drive mechanism 4 and the transmission shaft assembly 6, respectively. The lower feed roller 2 is driven by the main drive mechanism 4, or by the main drive mechanism 4 and the secondary drive mechanism 5. The transmission shaft assembly 6 has a transmission shaft 601, which is rotatably connected to the housing 1 and connected to the lower feed roller 2. The transmission shaft 601 and... The lower feed roller 2 rotates synchronously. The end of the drive shaft 601 opposite to the lower feed roller 2 is exposed in the housing 1. The end of the drive shaft 601 exposed in the housing 1 is provided with a drive hole 602. The drive hole 602 extends along the axial direction of the lower feed roller 2. The auxiliary drive mechanism 5 is detachably fixedly connected to the drive shaft 601 in the drive hole 602. The upper feed roller 3 is provided on one side of the lower feed roller 2 and is spaced apart from the lower feed roller 2 to form a feeding gap (not shown in the figure). The upper feed roller 3 can move relative to the lower feed roller 2 to adjust the feeding gap.

[0028] When the material to be conveyed is heavy or requires rapid conveying, the auxiliary drive mechanism 5 is mounted on the drive shaft 601. At this time, the lower feed roller 2 is driven by both the main drive mechanism 4 and the auxiliary drive mechanism 5. The lower feed roller 2 has a strong conveying capacity, enabling the feeder with stable power transmission to convey heavier or faster materials. When the material to be conveyed is light or requires slow conveying, the auxiliary drive mechanism 5 is removed from the drive shaft 601. At this time, the lower feed roller 2 is driven by the main drive mechanism 4. The conveying capacity of the lower feed roller 2 is reduced, enabling the feeder with stable power transmission to convey lighter or slower materials, making it flexible and versatile in use.

[0029] In summary, this embodiment provides a feeder with stable power transmission to solve the problem that the lower feed roller of the existing punch press feeder is driven by a single drive mechanism and cannot meet the power requirements for conveying. This is mainly achieved by configuring a transmission shaft assembly 6 at the end of the lower feed roller 2 away from the main drive mechanism 4. The transmission shaft assembly 6 has a transmission shaft 601 that is rotatably connected to the housing 1. The transmission shaft 601 is connected to the lower feed roller 2 and has a transmission hole 602. The transmission hole 602 is used for detachable fixed connection with the auxiliary drive mechanism 5. This allows the feeder with stable power transmission to increase the driving power by adding a drive mechanism when the power is insufficient, and to detach the auxiliary drive mechanism 5 when the power is sufficient to reduce the driving power. This enables the lower feed roller 2 to be driven by a single drive (only driven by the main drive mechanism 4) and by a dual drive (driven by the main drive mechanism 4 and the auxiliary drive mechanism 5), which provides strong driving force and flexible use.

[0030] In this embodiment of the invention, the housing 1 has an insertion hole (not shown in the figure) through which the lower feed roller 2 passes, and the drive shaft assembly 6 has a bearing 603, which passes through the drive shaft 601 and is fitted into the insertion hole. This arrangement, by configuring the insertion hole on the housing 1 and the bearing 603 fitted into the insertion hole on the drive shaft 601, ensures stable and smooth rotation of the drive shaft 601.

[0031] In this embodiment of the invention, the axial direction of the drive shaft 601 is defined as the front-to-back direction. The drive shaft assembly 6 has two limiting rings 604, which pass through the drive shaft 601 and cooperate to restrict the bearing 603 from moving back and forth relative to the drive shaft 601. The limiting rings 604 are detachably fixedly connected to the housing 1. The above arrangement, by configuring two limiting rings 604 on the drive shaft 601 to restrict the front-to-back movement of the bearing 603, ensures the stable assembly of the bearing 603.

[0032] In this embodiment of the present invention, one of the two limiting rings 604 is defined as a rear limiting ring 605, and the other limiting ring 604 is defined as a front limiting ring 606. The rear limiting ring 605 is located rearward, and the front limiting ring 606 is located forward. The housing 1 is provided with a front limiting hole (not shown in the figure) for inserting the front limiting ring 606. The front limiting ring 606 has a front stop portion 607 that extends rearward into the insertion hole and abuts against the bearing 603. The above arrangement ensures stable assembly of the front limiting ring 606 and the housing 1 by providing a front limiting hole for inserting the front limiting ring 606, and ensures stable assembly of the bearing 603 by providing a front stop portion 607 that extends into the insertion hole and abuts against the bearing 603.

[0033] In this embodiment of the invention, the drive shaft 601 has a rear shoulder 608, which cooperates with the front limiting ring 606 to restrict the forward and backward movement of the bearing 603. This arrangement, by configuring the rear shoulder 608 on the drive shaft 601 to cooperate with the front limiting ring 606 to restrict the forward and backward movement of the bearing 603, ensures stable assembly of the bearing 603.

[0034] In this embodiment of the invention, a limiting ring 606 and a drive shaft 601 are radially spaced to form a limiting gap (not shown in the figure). A retaining ring 609 is inserted through the drive shaft 601 and fitted into the limiting gap. The retaining ring 609 can elastically deform in the radial direction of the drive shaft 601. The retaining ring 609 has an outer retaining piece 610, an inner retaining piece 611, and a connecting piece 612. The outer retaining piece 610 and the inner retaining piece 611 are radially spaced. The connecting piece 612 connects the outer retaining piece 610 and the inner retaining piece 611. The outer retaining piece 610 abuts against the front limiting ring 606, and the inner retaining piece 611 abuts against the drive shaft 601 and is inclined backward from the outside to the inside. The above arrangement, by placing the retaining ring 609 between the drive shaft 601 and the front limiting ring 606, makes the drive shaft 601 stable in assembly.

[0035] In this embodiment of the invention, the lower feed roller 2 has a secondary mounting hole 201 for inserting a drive shaft 601. A secondary mounting gap (not shown in the figure) is formed between the drive shaft 601 and the wall of the secondary mounting hole 201. A secondary abutment 614 passes through the drive shaft 601. The secondary abutment 614 has an inner secondary stop ring 615 embedded in the secondary mounting gap and an outer secondary stop ring 616 abutting against the edge of the secondary mounting hole 201. This arrangement, by providing a secondary mounting hole 201 for inserting the drive shaft 601 on the lower feed roller 2 and a secondary abutment 614 at least partially embedded in the secondary mounting gap on the drive shaft 601, ensures stable assembly between the drive shaft 601 and the lower feed roller 2.

[0036] In this embodiment of the invention, two hydraulic tensioning sleeves 8 are mounted on the lower feed roller 2, and the two hydraulic tensioning sleeves 8 are spaced apart in the axial direction of the lower feed roller 2. This arrangement, by configuring two hydraulic tensioning sleeves 8 on the lower feed roller 2 and spaced apart in the axial direction of the lower feed roller 2, gives the lower feed roller 2 good load-bearing capacity and excellent material conveying effect.

[0037] In this embodiment of the invention, the main drive mechanism 4 is mounted on the housing 1 and has a main motor 401 that is connected to the lower feed roller 2. The output shaft of the main motor 401 is defined as the main output shaft 402. The lower feed roller 2 has a main mounting hole 202 for the main output shaft 402 to be inserted. The main output shaft 402 and the wall of the main mounting hole 202 are spaced apart to form a main mounting gap (not shown in the figure). A main abutment 403 is provided on the main output shaft 402. The main abutment 403 has a main inner stop ring 404 embedded in the main mounting gap and a main outer stop ring 405 abutting against the edge of the main mounting hole 202. The above arrangement makes the assembly of the lower feed roller 2 and the main output shaft 402 stable.

[0038] In this embodiment of the utility model, a cover 9 is provided on the housing 1. The cover 9 is detachably and fixedly connected to the housing 1 to cover one end of the drive shaft 601 exposed in the housing 1. The above-mentioned arrangement, by configuring the cover 9 on the housing 1 to cover one end of the drive shaft 601 exposed in the housing 1, avoids the transmission hole 602 being exposed when the feeder with stable power transmission is driven alone.

[0039] In this embodiment of the utility model, the auxiliary drive mechanism 5 is provided on the housing 1 and has an auxiliary motor 501 that is connected to the drive shaft 601. The output shaft of the auxiliary motor 501 is defined as the auxiliary output shaft 502, and the auxiliary output shaft 502 is inserted into the drive hole 602.
