Description

Technical Field

[0001] The utility model relates to the technical field of steel product processing, in particular to a punching and feeding device based on steel office furniture. Background Art

[0002] When producing and processing steel office furniture, it is usually necessary to perform hole drilling on its surface to facilitate the installation of other accessories. The drilling process usually involves placing the steel blank plate on a punching table for punching.

[0003] The current steel plate punching machines basically use hydraulic push rods or other driving devices to push the sheet to the punching station. Then, after the punching is completed, there are generally two solutions to remove the finished sheet on the punching station. One is to use the hydraulic push rod to continue to push the sheet forward. The defect of this process is that the hydraulic push rod has a long reset stroke and a long processing interval. The other solution is to use an additional unloading drive to push the finished sheet for unloading. The disadvantage of this solution is that additional drive components are required, and the unloading drive component needs to be controlled and coordinated with the loading drive component by a PLC control machine, which leads to increased equipment cost and control cost. For this purpose, a punching and feeding device based on steel office furniture is provided to solve the above problems. Utility Model Content

The former has a long reset stroke of the hydraulic push rod and a long processing interval, and the latter requires additional configuration of a drive component, which increases the cost.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a punching and feeding device based on steel office furniture, including a punching and feeding table and a punching station arranged on the top of the punching and feeding table, passive unloading mechanisms are arranged on both sides of the punching station, and an active loading clamp is arranged on the front side of the punching station, and the passive unloading mechanism includes;

In this process, the driving rack is synchronously driven to slide forward, and the driving rack drives the transmission gear to rotate. At this time, the ratchet groove does not transmit with the ratchet pawl, and then the hydraulic punching machine is started to punch holes. After the punching is completed, the feeding hydraulic push rod drives the active feeding clamping part to reset.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The embodiment of the present application provides a punching and feeding device based on steel office furniture, which solves the problem that after the punching of steel office furniture is completed, either a loading hydraulic push rod is used to continue to push the sheet material forward for unloading, or an additional unloading drive component is used to push the finished sheet material for unloading. The former has a long reset stroke of the hydraulic push rod and a long processing interval time, and the latter requires additional configuration of a drive component, which increases the cost.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] The utility model embodiment discloses a punching and feeding device based on steel office furniture.

[0025] According to the attached Figure 1-3 As shown, it includes a punching feeding table 1 and a punching station 4 arranged on the top of the punching feeding table 1, passive unloading mechanisms 8 are arranged on both sides of the punching station 4, and an active loading clamp 5 is arranged on the front side of the punching station 4, and the passive unloading mechanism 8 includes;

[0026] The unloading roller 81 is rotatably arranged on both sides of the punching station 4;

[0027] A transmission gear 85 is mounted on the outer surface of one end of the unloading roller shaft 81, and the transmission gear 85 is connected to the unloading roller shaft 81 in a one-way transmission manner;

[0028] The driving rack 11 is fixedly disposed on both sides of the active feeding clamp 5 , and the driving rack 11 is meshed with the transmission gear 85 .

[0029] A ratchet pawl 84 is installed on the outer surface of one end of the unloading roller shaft 81 , and a ratchet groove 86 is provided inside the transmission gear 85 , and the ratchet pawl 84 meshes with the ratchet groove 86 .

[0030] A non-slip rubber sleeve 83 is fixedly installed on the end of the unloading roller 81. The non-slip rubber sleeve 83 is used to increase the friction resistance of the unloading roller 81 when it rotates. When the transmission gear 85 rotates clockwise, it will not drive the unloading roller 81 to rotate. The outer surface of the unloading roller 81 is fixedly sleeved with a unloading friction sleeve 82. The unloading friction sleeve 82 can prevent slipping with the steel plate during unloading.

[0031] Slide grooves 9 are provided on both sides of the punching and feeding platform 1 , and a sliding connection member 10 is fixedly connected between the active feeding clamp 5 and the driving rack 11 , and the sliding connection member 10 is slidably arranged inside the slide groove 9 .

[0032] A gantry 2 is provided on the top of the punching station 4 , and a hydraulic punching machine 3 is installed on the gantry 2 . Punching is achieved by installing a punching tool at the output end of the hydraulic punching machine 3 .

[0033] A movable groove 7 is provided on the top of the punching and feeding platform 1 , and a feeding hydraulic push rod 6 is installed inside the movable groove 7 . The output end of the feeding hydraulic push rod 6 is fixedly connected to the active feeding clamp 5 .

[0034] Limiting grooves 12 are provided at the bottom of both sides of the active feeding clamp 5. The limiting grooves 12 are used to limit and fix the steel plate when punching. When punching, the steel plate blank is confined inside the limiting grooves 12 to prevent the steel plate from shaking significantly. It is suitable for processing operations that do not require high punching position accuracy.

[0035] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0036] When the device is in use, the feeding hydraulic push rod 6 drives the active loading clamp 5 to move forward, and the active loading clamp 5 limits the steel plate blank through the limiting groove 12 at its bottom, and drives the steel plate blank to move synchronously to the punching station 4. In this process, the driving rack 11 is synchronously driven to slide forward, and the driving rack 11 drives the transmission gear 85 to rotate. At this time, the ratchet groove 86 does not transmit with the pawl 84, and then the hydraulic punching machine 3 starts to punch. After the punching is completed, the feeding hydraulic push rod 6 drives the active loading clamp 5 to reset. At this time, the driving rack 11 slides outward and drives the unloading roller 81 to rotate counterclockwise through the transmission gear 85. At this time, the active loading clamp 5 is removed from the surface of the sheet material, so that the unloading roller 81 drives the sheet material to slide and unload in the opposite direction. The feeding stroke is short, time is saved, and no additional unloading drive parts are required.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
