The drawings includes following integers denoting the various components:
The present invention will be described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.
As shown in
The reciprocating feeding of the feed motor 5 is used to matching the reciprocating lifting of the lift cylinder, which may realize the reciprocating feeding and lifting of the feeding block. Further, the sheet body on the feeding trough can be fed for a fixed distance, and sequentially passes through the punching device and the grinding device. The integrated punching and grinding of the sheet body greatly improves the overall processing efficiency of the sheet body.
As shown in
By developing the structure of the feed blocks, the feed block can support the sheet body, and the punching and grinding effect of the sheet body can be improved, and a discharging opening is disposed to match the collect device, and the punching and grinding reject can be collected, thereby avoids interference with the feed portion.
As shown in
Both the punching device and the grinding device are provided on the processing lift seat, so that the synchronous grinding can be achieved, and forces are in a balance. Meanwhile, it is also possible to detect the feeding precision from the processing conditions of the two processing parts. By providing a compactable material pressing plate cooperating with the grinding head by plugging and fitting, during descending of the grinding head, interference with the material pressing part will not occur, which achieves good material holding effect for grinding.
As shown in
The beam emitter is used to emit a vertical beam passing through the discharging opening, and the receiving condition of the beam receiver can be used to determine whether the feeding is accurate. If the beam receiver receives the beam from the beam emitter, the feeding is accurate, and the sheet body is fed to the accurate grinding station. Otherwise, there is an error in feeding distance and the device needs to be shut down for maintenance.
As shown in
By developing of the first contact sensor the measurement position of the acoustic range finders can be determined, the measurement of the acoustic range finders can detect the height of the vertical part of the feeding block, thus ensure the precise lifting of the feeding block. The processing lift cylinder stops lifting when the first contact sensor generates an inductive signal. If the values measured by the two acoustic range finders are consistent with the theoretical values, the feeding height is accurate, and as long as one measured values are different from the theoretical values, there is a problem with accuracy of the feeding height. Together with signal of the beam receiver, it can be judged whether the feeding distance is not accurate or the lifting accuracy is not accurate.
As shown in
The structure of the second contact sensor can cooperate with the first contact sensor to reflect whether the thickness of the sheet is consistent, if the first contact sensor and the second contact sensor simultaneously generate sensing signals, the thickness of the products at the punching station and the grinding station is consistent, and the value measured by the acoustic range finder is more accurate. If the first contact sensor and the second contact sensor do not simultaneously generate the sensing signal, the thickness of products at the punching station and the grinding station is inconsistent.
The lower portion of the processing lift seat 22 is provided with a punching rotary motor 36, the punching head 37 is provided under the punching rotary motor 36, and the lower portion of the punching head 37 is an rotary cutter, and the upper end thereof is a baffle block larger than the punching diameter. The structural design of the punching head, combined with the design of the punching rotary motor, can achieve a better punching effect, and can also avoid excessive punching, thereby damaging the feeding block.
As shown in
The collect device realizes the rotation of the support rotating block through the rotation of the collect assembly motor, thereby the support and discharge of the collect frame can be realized, which may play a good role in collecting and discharging rejects. Meanwhile, it can also guide the lifting of the feed lift block, and when feeding at left and right orientation, the movable feed seat and the feed lift block can be operated synchronously.
The overall operation is as follows:
Debug the device first, then put the iron sheet into the left part of the feeding slot 3 on the feeding slot seat 2; rotate the feeding screw 6 by the feeding motor 5, thereby drive the movable feeding seat 8 to move to the left, thereby the feeding block 11 is moved to the left of the sheet body 5; the feeding lift cylinder 9 drives the feeding lift block 10 to move up, thereby the feed block 11 is raised and vertical portion thereof passing through the feeding slot 3; the feed motor 5 is rotated reversely to drive the feed screw 6 to rotate reversely, thereby drive the feeding block 11 to move to the right; during that, the sheet body 4 is touched and is driven to move to the right by a certain distance to complete a fixed distance movement. Subsequently, the sheet body is repeatedly placed and moved for a fixed distance, the first sheet body will be fed to the punching station by the feeding block 11 matching the punching station during the process of feeding for a fixed distance; then the processing lifting cylinder 21 drives the processing lifting seat 22 to descend, and stops when the second contact sensor 38 generates a sensing signal. The acoustic range finder 34 performs measuring, if the values measured by the two acoustic range finders are consistent with the theoretical values, the feeding is accurate, if the values measured by the two acoustic range finder are consistent but not consistent with the theoretical values, there is a problem with the lifting height of the feeding block 11, which requires maintenance. If the two measured values differ greatly, irradiate a beam with the beam emitter 29 and if the beam receiver 25 receives the beam emitted by the beam emitter 29, the position of the acoustic range finders needs adjusting, if the beam receiver 25 does not receive the beam emitted by the beam emitter 29, the feeding of the feeding block is not accurate.
After the above-mentioned integrity detection is performed, the processing lift cylinder 21 drives the processing lift seat 22 to continue to descend, thereby the punching head 37 contacts the product, and the punching rotary motor 36 drives the punching head 37 to rotate and punch, and thereby completes the punching process; thereafter return the processing lift cylinder 21 to its original position, and convey the next sheet body to the punching station by the way of cooperation of left-right reciprocating motion and lifting reciprocating motion of the feeding block; the punched sheet body will be fed to the grinding station, and the feeding distance and lifting height of the feeding block is detected in the same way; in the detection process, there is one more step, that is, whether the first contact sensor and the second contact sensor synchronously generate sensing signal; if the sensing signal is generated synchronously, the thickness of the sheet body is consistent, if the sensing signal is not generated synchronously, the thickness of the sheet body is inconsistent and needs to be reviewed; after that, the processing lift cylinder 21 continues to descend, and the punching device runs just like before. The grinding device 14 drives the grinding head 24 to rotate by the grinding motor 23, and finishes the grinding by fitting with the lifting of the processing lift cylinder 21, then repeats the above process until the sheet body is completely processed.
