Description

Technical Field

[0001] This utility model relates to the field of press technology, and in particular to an automatic cleaning device for press worktables. Background Technology

[0002] Currently, presses are a type of mechanical equipment widely used in metal processing, plastic molding, and stamping processes.

[0003] In the prior art, the worktable of a press is generally located below the stamping head. After the workpiece is stamped, the workpiece debris inevitably falls onto the surface of the worktable. For example, in the published patent document CN212446481U, the debris on the worktable falls to the bottom of the worktable through a through hole by vibration, and the remaining debris is then cleaned by a scraper. The setting of the through hole will cause deformation during the stamping process, and the vibration effect and the cleaning effect of the scraper are limited, which affects the stamping and shaping of subsequent workpieces and reduces product quality.

[0004] Therefore, there is an urgent need to propose a more reasonable cleaning structure. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing an automatic cleaning device for the worktable of a press, which includes an automatic cleaning mechanism for the working head and a baffle that can move up and down to clean the worktable.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] An automatic cleaning device for the worktable of a press includes a press and a worktable mounted on the press. Several lifting groups are respectively arranged on both sides of the worktable. Each lifting group includes a cylinder, a slide groove, and a slider. The cylinder is located below the slide groove, the piston rod in the cylinder is located at the bottom of the slider, and a baffle is provided at the front end of the slider.

[0008] The workbench is provided with a workstation for placing workpieces, and a blower is provided on the workbench, with the blower located behind the workstation.

[0009] In the above scheme, preferably, the slide is provided with an outer frame, and the outer frame is located outside the baffle.

[0010] In the above scheme, preferably, a support plate is provided on the front side of the workbench, and a storage box is provided on the support plate.

[0011] In the above scheme, preferably, the front end of the storage box is provided with an inclined plate, and the inclined plate is fixed to the front end of the storage box.

[0012] In the above scheme, preferably, a control motherboard is also provided on the front side of the workbench, and the control motherboard is located below the support plate.

[0013] In the above scheme, preferably, the control motherboard is provided with a switch for starting or stopping the press, and a controller for setting the blowing time of the blower is provided on one side of the switch.

[0014] In the above scheme, preferably, the press includes a punch head, and an infrared sensor is provided on one side of the punch head, the infrared sensor being located on the outer wall of the press.

[0015] The beneficial effects of this utility model are as follows: By setting up a baffle, this utility model can concentrate the debris that falls off the workpiece after stamping on the worktable. After the stamping block completes the stamping work, the stamping head rises to the initial position. The infrared sensor on one side of the stamping head receives the signal and transmits it to the controller to make the blower work. The setting of the collection box can blow the debris into the collection box, which is convenient for cleaning the press worktable, so as to facilitate the stamping and shaping of subsequent workpieces and improve product quality.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0023] See Figures 1-6 The automatic cleaning device for the worktable of the press includes a press 1 and a worktable 2 set on the press 1. The press 1 includes a punch head 16 for punching workpiece 6. The punch head 16 is located directly above the worktable 2. Several sets of lifting groups are respectively set on both sides of the worktable 2.

[0024] Specifically, as shown in the figure, two sets of lifting groups are provided on one side of the workbench 2. The lifting group consists of a cylinder 17, a slide 3, and a slider 4. The principle of the cylinder 17 is to convert hydraulic energy into mechanical energy to achieve linear reciprocating motion. In this embodiment, the cylinder 17 is located below the slide 3, with its bottom on the ground. The piston rod 18 in the cylinder 17 is located at the bottom of the slider 4, and the end of the piston rod 18 is fixed to the bottom of the slider 4. When the cylinder 17 works, it drives the slider 4 to move up and down in the slide 3. The lifting group on the other side of the workbench 2 has the same structure. In order to block the debris generated after the stamping work is completed on the workbench surface, a baffle 5 is provided at the front end of the slider 4. The other side of the baffle 5 is fixed to the front end of another slider 4. In order to prevent debris from falling from the gap between the baffle 5 and the workbench 2, an outer frame 9 is provided between the two sets of slide 3. One side of the outer frame 9 is fixed to the outer wall of the workbench 2, which can prevent debris from flying out of the workbench 2 surface.

[0025] Furthermore, when it is necessary to clean the debris on the workbench 2, a blower 8 is provided on the workbench 2. The blower 8 is located on the rear side of the work station 7. As shown in the figure, the blower 8 is set on the workbench 2, and its long strip-shaped air outlet extends from one end of the workbench surface to the other end to improve the overall cleaning effect of the workbench surface.

[0026] The blower 8 can be an industrial blower, with its main body located below the machine body. It is fluidly connected to the air outlet located on the workbench 2 through a pipe. The blower 8 can blow away debris on the workbench 2. To prevent the blower 8 from blowing debris away and making it difficult to clean, a support plate 10 is provided on the front side of the workbench 2. The support plate 10 is fixed to the front side of the workbench 2. A collection box 11 for collecting debris is provided on the support plate 10. An inclined plate 12 is provided at the front end of the collection box 11 and is fixed to the front end of the collection box 11. The collection box 11 can be a whole. The height of the collection box 11 does not affect the worker's placement and removal of smaller and lighter workpieces 6. When the workpiece 6 is larger and heavier, because the height of the collection box 11 exceeds the workbench surface, the workpiece 6 cannot enter along the edge of the workbench surface. The part of the collection box 11 that exceeds the workbench surface can be flipped so that the collection box 11 is on the same plane as the workbench surface.

[0027] Before the blower 8 starts blowing air, the baffle 5 moves upward to its highest position via the cylinder, and the workpiece 6 on the workstation 7 is not removed. The debris on the workbench will enter the storage box 11 along the inclined surface of the inclined plate 12. This makes it convenient to collect debris while cleaning the workbench. When the storage box 11 collects too much debris, it can be removed to clean the debris inside. After cleaning the debris inside the storage box 11, the storage box 11 can be placed on the support plate 10 to collect the debris on the workbench.

[0028] As one implementation method, louvers that can be adjusted up and down are provided at the air outlet. The louvers are adjusted to be tilted downward so that the blown air flows in a downward tilted path, preventing debris from being carried away.

[0029] Of course, the air outlet can also be equipped with fixed louvers, which can be set to tilt downwards.

[0030] In this embodiment, a control main board 13 is also provided on the front side of the workbench 2. The control main board 13 is located below the support plate 10. The control main board 13 is provided with a switch 14 for starting or stopping the press 1. A controller 15 for setting the blowing time of the blower 8 is provided on one side of the switch 14. The cylinder 18 is also started by the controller 15 to drive the baffle 5 to rise and fall. An infrared sensor 17 is provided on one side of the punch head 16. The infrared sensor 17 is electrically connected to the controller 15 and is fixed on the outer wall of the press 1. The infrared sensor 17 is used to sense whether the stamping head 16 has risen to a predetermined position. The predetermined position is the initial position that the stamping head 16 returns to after stamping. After the infrared sensor 17 senses that the stamping head 16 has reached the predetermined position, it transmits a signal to the controller 15. Before the controller 15 receives the signal, the cylinder 18 raises through the piston rod 19 in the cylinder 18 to drive the baffle 5 to the highest position. The controller 15 controls the blower 8 to start blowing. The blowing time is the set time, such as 5s or 10s. The set time can be selected according to actual needs.

[0031] When the stamping head 16 descends, it leaves the receiving range of the infrared sensor 17, and the infrared sensor 17 can no longer receive a signal.

[0032] Working principle: Before the stamping operation, the initial state of the baffle 5 is as shown in the figure. The piston rod in the cylinder rises to the highest position. The switch 14 to start the press 1 is pressed. The controller 15 on the main board 13 sets the blowing time of the blower 8. After the stamping operation, the stamping block 16 rises to the initial position. The infrared sensor 17 on one side receives the signal that the stamping head 16 has reached the designated position and transmits the signal to the controller 15. The blower 8 then blows air. During the blowing operation, the workpiece 6 on the station 7 is not removed. The blowing time is the time set by the controller 15 before the stamping operation. The blower 8 blows the debris on the worktable into the collection box 11 through the inclined surface of the inclined plate 12 for collection. After the blowing is finished, the controller 15 starts the cylinder 18 to lower the piston rod 18, which drives the baffle 5 to the lowest position (failure to lower it will affect the replacement of the workpiece or mold). The workpiece 6 that has finished the stamping operation on the station 7 is removed and a new workpiece 6 is placed for stamping.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
