[0002] Metal pressing is a process that uses special presses and molds to press metal sheets into the required shapes and specifications. Metal pressing equipment is required to press metal raw materials into parts or products of various shapes and specifications.

[0003] A precious metal tablet press, with application number CN201621104396.5, includes a base, a tablet pressing roller assembly mounted on the base, and a drive mechanism for driving the tablet pressing roller assembly. The tablet pressing roller assembly includes two support frames, an upper roller, and a lower roller. The two ends of the lower roller are fixed axially and radially on the two support frames, and the lower roller can rotate around a central axis. The two ends of the upper roller are fixed axially and can rotate around a central axis, mounted on the two support frames. The upper roller is located directly above the lower roller and parallel to the lower roller. Each of the two support frames is provided with an adjustment mechanism for adjusting the radial movement of the two ends of the upper roller in the vertical direction. The corresponding ends of the upper and lower rollers are linked to the drive mechanism.

[0004] The device manipulates the manual lever to rotate the adjusting rod, thereby causing the adjusting rod to move axially in the threaded through hole under the lifting force of the thread, which in turn drives the slider to slide up and down in the sliding groove hole, thereby adjusting the gap between the upper and lower rollers. However, the device requires manual adjustment when adjusting the gap between the rollers, and improper operation can easily cause the worker's hand to be squeezed, which is dangerous.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing variable thickness metal pressing device structure. Utility Model Content

[0006] The purpose of this invention is to provide a variable thickness metal pressing device to solve the problem mentioned in the background art that the device requires manual adjustment when adjusting the gap between the rollers, which can easily cause injury to the worker's hands if not operated properly, posing a certain danger.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a variable thickness metal pressing device, including a connecting plate, a support frame provided on the outside of the connecting plate, and a drive motor fixedly installed on the outside of the support frame, a pressing roller fixedly installed on the output end of the drive motor, and two sets of pressing rollers symmetrically arranged about the midpoint of the connecting plate; and an adjustment component installed on the outside of the connecting plate.

[0008] A lubrication assembly is installed on the upper end of the support frame. Driving the adjustment assembly can adjust the position of the tableting rollers at both ends. The lubrication assembly can lubricate the tableting rollers.

[0009] Preferably, the adjustment assembly includes a fixed plate, a servo motor, and a counter-rotating threaded rod. The fixed plate is fixedly installed on the outside of the connecting plate, and the servo motor is fixedly installed on the outside of the fixed plate. The output end of the servo motor is fixedly connected to the counter-rotating threaded rod.

[0010] Preferably, the adjustment assembly further includes a threaded connector and a slide groove. The threaded connector is threaded to the left and right sides of the opposite threaded rod and is connected to the outside of the support frame. The bottom of the threaded connector is nested inside the slide groove, and the slide groove is opened inside the connecting plate.

[0011] Preferably, the lubrication assembly includes a storage box, a discharge pipe, and a nozzle. The storage box is fixedly installed on the top of the support frame, and the bottom of the storage box is fixedly connected to the discharge pipe. The discharge pipe passes through the inside of the support frame, and the lower end of the discharge pipe is fixedly connected to the nozzle. The nozzle and the tableting roller are distributed vertically in correspondence.

[0012] Preferably, the lubrication assembly further includes a sealing plate, a telescopic spring, and a rack. The sealing plate extends through the inside of the discharge pipe, and a telescopic spring is connected between the tail of the sealing plate and the outer wall of the discharge pipe. A rack is fixedly connected to the outside of the sealing plate.

[0013] Preferably, the lubrication assembly further includes a first drive shaft, a drive belt, a second drive shaft, and a concentric shaft. The first drive shaft is fixedly installed at the output end of the drive motor, and the first drive shaft is connected to the second drive shaft via the drive belt. A concentric shaft is fixedly installed on the inner side of the second drive shaft, and the concentric shaft is rotatably connected to the inner side of the support frame.

[0014] Preferably, the lubrication assembly further includes a gear, which is fixedly mounted on the outside of a concentric shaft, and the concentric shaft has a half-tooth structure when viewed from the side. A rack is meshed with the outside of the gear.

[0015] Compared with the prior art, the beneficial effect of this utility model is that the variable thickness metal pressing device is provided with:

[0016] 1. Thickness adjustment structure: When it is necessary to adjust the gap between the rollers, this structure operates a servo motor, which drives the anti-directional threaded rod to rotate. The rotation of the anti-directional threaded rod will cause the threaded connectors at both ends to move in opposite directions. The opposite or reverse movement of the two sets of threaded connectors will cause the pressing rollers at both ends to move together, thereby adjusting the gap between the pressing rollers at both ends and thus adjusting the thickness of the metal pressing.

[0017] 2. Lubrication structure: When the output of the drive motor drives the tableting roller to rotate, it will simultaneously drive the concentric shaft to rotate through the transmission belt. The rotation of the concentric shaft will drive the outer gear to rotate as well. When the gear teeth mesh with the rack, it will drive the sealing plate to slide outward along the inside of the discharge pipe, so that the discharge pipe is in an open state. Lubricating oil is delivered to the outside of the tableting roller through the material nozzle. Through the lubrication of the lubricating oil, the friction between the tableting roller and the metal sheet is reduced, the service life of the equipment is extended and the maintenance cost is reduced.

[0018] Furthermore, when the gear teeth separate from the rack, the sealing plate will be reset by the elastic force of the telescopic spring, thereby closing the discharge pipe and stopping the delivery of lubricating oil. Through the reciprocating operation of the above structure, the effect of intermittent feeding is achieved, avoiding the waste of resources caused by continuous addition of lubricating oil.

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] Please see Figures 1-6 This utility model provides a technical solution: a variable thickness metal pressing device, comprising:

The adjustment component 5 drives the tablet pressing rollers 4 at both ends to adjust their positions; the lubrication component 6 lubricates the tablet pressing rollers 4.

[0029] The adjustment assembly 5 includes a fixed plate 501, a servo motor 502, and a counter-rotating threaded rod 503. The fixed plate 501 is fixedly installed on the outside of the connecting plate 1, and the servo motor 502 is fixedly installed on the outside of the fixed plate 501. The output end of the servo motor 502 is fixedly connected to the counter-rotating threaded rod 503. The adjustment assembly 5 also includes a threaded connector 504 and a slide groove 505. The threaded connector 504 is threadedly connected to the left and right sides of the counter-rotating threaded rod 503, and the threaded connector 504 is connected to the outside of the support frame 2. The bottom of the threaded connector 504 is nested inside the slide groove 505, and the slide groove 505 is opened inside the connecting plate 1.

[0030] When this structure requires adjustment of the gap between the rollers, the servo motor 502 is operated, causing the output end of the servo motor 502 to drive the anti-directional threaded rod 503 to rotate. The rotation of the anti-directional threaded rod 503 will cause the threaded connectors 504 at both ends to move in opposite directions. The opposite or reverse movement of the two sets of threaded connectors 504 will cause the pressing rollers 4 at both ends to move together, thereby adjusting the gap between the pressing rollers 4 at both ends, and thus achieving the effect of adjusting the thickness of the metal pressing.

[0031] Example 2: Figures 1-2 , Figure 4-Figure 6The present invention provides a technical solution: a variable thickness metal tablet pressing device, which discloses that: the lubrication component 6 includes a storage box 601, a discharge pipe 602, and a nozzle 603. The storage box 601 is fixedly installed on the top of the support frame 2, and the discharge pipe 602 is fixedly connected to the bottom of the storage box 601. The discharge pipe 602 penetrates the inner side of the support frame 2, and the nozzle 603 is fixedly connected to the lower end of the discharge pipe 602. The nozzle 603 and the tablet pressing roller 4 are distributed vertically and vertically respectively. The lubrication component 6 also includes a sealing plate 604, a telescopic spring 605, and a rack 606. The sealing plate 604 penetrates the inner side of the discharge pipe 602, and the tail of the sealing plate 604 is connected to the outer wall of the discharge pipe 602. The lubrication assembly 6 includes a telescopic spring 605 and a rack 606 fixedly connected to the outer side of the sealing plate 604; the lubrication assembly 6 also includes a first drive shaft 607, a drive belt 608, a second drive shaft 609, and a concentric shaft 610.

The rack 606 is meshed with the outer side of the gear 611.

[0032] When the output of the drive motor 3 drives the tableting roller 4 to rotate, it will simultaneously drive the concentric shaft 610 to rotate through the transmission belt 608. The rotation of the concentric shaft 610 will drive the outer gear 611 to rotate as well. When the tooth surface of the gear 611 meshes with the rack 606, it will drive the sealing plate 604 to slide outward along the inner side of the discharge pipe 602, so that the discharge pipe 602 is in an open state. Lubricating oil is delivered to the outside of the tableting roller 4 through the nozzle 603. Through the lubrication of the lubricating oil, the friction between the tableting roller 4 and the metal sheet is reduced, the service life of the equipment is extended and the maintenance cost is reduced. When the tooth surface of the gear 611 separates from the rack 606, the sealing plate 604 will be reset by the elastic force of the telescopic spring 605, so that the discharge pipe 602 is closed and the delivery of lubricating oil stops. Through the reciprocating operation of the above structure, the effect of intermittent feeding is achieved, avoiding the waste of resources caused by continuous addition of lubricating oil.
