DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] The license plate edge material punching machine tool described in the utility model comprises a workbench 1. Figure 1 As shown, the workbench 1 is arranged horizontally and four vertical support columns 4 are welded on the top. The four support columns 4 are arranged in a rectangular array and the top ends are fixedly connected to the same horizontal support plate 3. The top of the support plate 3 is bolted with a vertical hydraulic cylinder 2, and the output end of the hydraulic cylinder 2 slides vertically downward through the support plate 3 and is fixed with a mounting press head 5 for stamping.

[0025] A blanking hole 6 is drilled on the workbench 1, and the blanking hole 6 corresponds to the pressure head 5. A blanking pipe 7 is fixedly connected to the bottom of the workbench 1, and the blanking pipe 7 is connected to the blanking hole 6. A material receiving box 8 is fixedly connected to the end of the blanking pipe 7 away from the blanking hole 6. A feed port 14 is cut out on the top of the material receiving box 8, and the feed port 14 is connected to the blanking pipe 7 and the material receiving box 8, and is used to pass the license plate edge material after stamping.

[0026] A matching material receiving frame 12 is slidably assembled in the material receiving box 8, and a material receiving opening for receiving materials is reserved at the top of the material receiving frame 12. An opening matching the material receiving frame 12 is cut out on one side of the material receiving box 8, so that the material receiving frame 12 can slide in or out of the material receiving box 8.

[0027] like Figure 4As shown, two first through holes 9 are cut on the bottom box body of the receiving box 8, and the two first through holes 9 are parallel to each other to form a guide track. The bottom of the receiving frame 12 is screwed with four universal wheels 17 distributed in a rectangular array, and the universal wheels 17 match the first through holes 9 and roll along the guide of the first through holes 9.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a clearance groove 11 is cut on the frame body of the material receiving frame 12, and a matching handle 13 is installed in the clearance groove 11, and the handle 13 is rotatably connected to the material receiving frame 12. The clearance groove 11 is used to store the handle 13 to ensure that the handle 13 is not damaged during daily production operations. A buckle groove 10 is provided on the frame body of the material receiving frame 12, and the buckle groove 10 is connected to the clearance groove 11, so that it is convenient to hold the handle 13 and turn the handle 13 out of the clearance groove 11, and then push and pull the material receiving frame 12.

[0029] Two cylindrical second through holes 19 are drilled on the frame of the material receiving frame 12. The two second through holes 19 are horizontally opposite and distributed on the left and right sides of the clearance groove 11. The two second through holes 19 are both connected to the clearance groove 11. Two rectangular slide grooves 18 are dug out on the frame of the material receiving frame 12. The two slide grooves 18 correspond to the two second through holes 19 one by one, and each slide groove 18 is connected to the corresponding second through hole 19. Rectangular limiting grooves 20 are cut on the box body of the material receiving box 8 on the left and right sides of the opening. The notches of the two limiting grooves 20 are horizontally opposite. The two limiting grooves 20 correspond to the two slide grooves 18 one by one, and each limiting groove 20 is connected to the corresponding slide groove 18 in a docking manner.

[0030] Each second through hole 19 is equipped with a driving member, and each slide groove 18 is equipped with a limiting member. The handle 13 is connected to the driving member in a transmission manner, and the driving member is connected to the limiting member in the slide groove 18 connected to the second through hole 19 in a transmission manner, and the limiting member is in contact with the limiting groove 20 corresponding to the slide groove 18 in which it is located.

[0031] like Figure 3 and Figure 5 As shown, the driving member includes a screw rod 16 and a sleeve 21. The sleeve 21 is fixedly connected to the handle 13. The rotation axis of the handle 13 is colinear with the central axis of the sleeve 21. A screw rod 16 is rotated and inserted into each second through hole 19, and the ends of the two screw rods 16 close to the handle 13 are coaxially fixedly connected to the sleeve 21, and the ends of the two screw rods 16 away from the handle 13 are inserted into the slide groove 18 connected to the second through hole 19 and are transmission-connected to the limiter.

[0032] The limiting member includes a limiting pin 15, each of which is a rectangular block. The limiting pin 15 is slidably engaged in the slide groove 18 and is threadedly connected with the screw rod 16 inserted into the slide groove 18, ensuring that when the screw rod 16 rotates, the limiting pin 15 only slides along the slide groove 18. Each limiting pin 15 matches the limiting groove 20 corresponding to the slide groove 18 and is contact-sliding engaged, ensuring that the limiting pin 15 does not rotate after sliding into the limiting groove 20.

[0033] Working principle: Place the license plate edge material on the workbench 1, then start the hydraulic cylinder 2, the output end of the hydraulic cylinder 2 drives the pressure head 5 to move towards the license plate edge material, and then stamp the license plate edge material. The formed license plate edge material will fall into the drop tube 7 through the drop hole 6, and then fall into the receiving frame 12 through the drop tube 7.

[0034] When the receiving frame 12 is full, the operator holds the handle 13 from the buckle slot 10, and then rotates the handle 13 upward, so that the handle 13 rotates out of the clearance slot 11 and drives the shaft sleeve 21 to rotate, and the shaft sleeve 21 drives the two screws 16 to rotate. The two screws 16 push the connected limit pins 15 to slide out of the corresponding limit slots 20. When the handle 13 is rotated upward to the limit position, the limit pins 15 just completely slide out of the corresponding limit slots 20 and release the limit on the receiving frame 12. Then the worker pulls the handle 13 to pull the receiving frame 12 out of the receiving box 8.

[0035] After the formed license plate edge material is taken out, the material receiving frame 12 is completely pushed into the material receiving box 8 through the handle 13. Then the handle 13 is turned downward, the handle 13 drives the shaft sleeve 21 to rotate, and the shaft sleeve 21 drives the two screw rods 16 to rotate. The two screw rods 16 push the connected limit pin 15 to slide out of the slide groove 18 and insert it into the corresponding limit groove 20. When the handle 13 completely enters the clearance groove 11 and returns to its original position, a part of the limit pin 15 is inserted into the limit groove 20 to form a clamping limit fit with the limit groove 20.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
