Description

Technical Field

[0001] This utility model relates to the field of punching processing technology, and more specifically, to a punching forming machine. Background Technology

[0002] With the rapid development of modern industrial manufacturing technology, the processing needs of metal and non-metal materials are becoming increasingly diversified, especially in the fields of automobile manufacturing, building decoration, home appliance production, and electronic equipment, which place higher demands on the punching and forming processes of pipe and sheet metal parts.

[0003] Existing punching forming machines are generally hydraulic punching machines, which include an upper die and a lower die. The sheet material to be processed is placed on the lower die, and then the upper die is pressed down by the hydraulic press to complete the punching operation.

[0004] Regarding the aforementioned technologies, both the upper and lower dies are fixedly mounted on the upper and lower die bases by several bolts. When the punching size of the product to be processed is different and the upper and lower dies need to be replaced, the bolts need to be unscrewed one by one to complete the replacement, which is inefficient and affects the processing efficiency. Utility Model Content

[0005] Therefore, in order to solve the problem of low mold changing efficiency, this utility model provides a punching forming machine, the specific technical solution of which is as follows:

[0006] A punching forming machine includes a mounting frame, a sliding plate, an upper die, a lower die, and a driving component. The upper die is located directly above the lower die and is mounted on the sliding plate. The lower die is mounted on the mounting frame. The sliding plate is slidably mounted on the mounting frame in a direction closer to or further away from the lower die. The driving component is used to drive the sliding plate to slide. An upper mounting plate is fixedly mounted on the upper die. An upper slide rail is mounted on the side of the sliding plate near the lower die. The upper mounting plate is slidably mounted on the upper slide rail. A first locking member is mounted on the sliding plate to lock its position. A lower slide rail is mounted on the mounting frame directly below the sliding plate. A lower mounting plate is fixedly mounted on the lower die and is slidably mounted on the lower slide rail. A second locking member is mounted on the mounting frame to lock its position.

[0007] By adopting the above technical solution, when it is necessary to replace different upper and lower dies, the constraints on the upper and lower dies are first released by the first and second locking components respectively. Then, the upper mounting plate and the lower mounting plate are directly pulled away from the upper slide rail and the lower slide rail respectively to complete the disassembly of the upper and lower dies. Next, the appropriate upper and lower dies are slid back onto the upper slide rail and the lower slide rail, and the upper mounting plate of the upper die and the lower mounting plate of the lower die are locked by the first and second locking components to complete the installation of the new upper and lower dies. The above installation process makes the replacement of upper and lower dies simple and quick, greatly improving processing efficiency.

[0008] Furthermore, a pair of lower sliding rails are provided, with the two lower sliding rails arranged horizontally opposite each other. Sliding grooves are provided on the opposite sidewalls of the two lower sliding rails. Sliding strips are provided on both sides of the lower mounting plate, and the sliding strips are slidably installed on the lower sliding rails through the sliding grooves.

[0009] Furthermore, the second locking member includes an abutment block and a locking block. Both ends of the sliding groove extend beyond the lower sliding rail. The abutment block is installed at one end between the two lower sliding rails, and one end of the upper mounting plate abuts against the abutment block. The locking block is rotatably installed at the end of the lower sliding rail away from the abutment block, and the locking block abuts against the end of the lower mounting plate away from the abutment block.

[0010] Furthermore, the pivot of the locking block is a bolt, which passes through the locking block and is threaded onto the lower slide rail.

[0011] Furthermore, a handle is installed at the end of the lower mounting plate away from the abutment block.

[0012] Furthermore, the mounting frame includes an upper support, a lower support, and several guide rods. The upper support and the lower support are arranged opposite each other in the vertical direction, and the lower mold is mounted on the lower support. Several guide rods are arranged circumferentially between the upper support and the lower support. The two ends of the guide rods are respectively fixedly mounted on the upper support and the lower support. The guide rods all pass through the sliding plate, and the sliding plate is slidably mounted on the guide rods.

[0013] Furthermore, the driving component is a hydraulic cylinder, which is fixedly mounted on the upper bracket, and the piston rod of the driving component is connected to the sliding plate.

[0014] Furthermore, each guide rod is fitted with a guide sleeve, which is fixedly installed on the sliding plate and slidably installed on the guide rod.

[0015] Furthermore, a limiting ring is installed on the guide rod, and the limiting ring is arranged opposite to the guide sleeve. When the upper mold is in the initial state, the distance between the limiting ring and the guide sleeve is the maximum stroke of the upper mold. Attached Figure Description

[0027] like Figure 1 As shown, a punching forming machine according to one embodiment of the present invention includes a mounting frame 1, a sliding plate 2, an upper die 3, a lower die 4, and a driving component 5. The mounting frame 1 includes an upper support 11, a lower support 12, and a plurality of guide rods 13. The upper support 11 and the lower support 12 are both rectangular plates and are arranged opposite each other in the vertical direction. The plurality of guide rods 13 are arranged circumferentially between the upper support 11 and the lower support 12, and are respectively located at the four corner positions of the upper support 11 and the lower support 12. The two ends of the guide rods 13 are respectively fixedly installed on the upper support 11 and the lower support 12. 2; The upper mold 3 is installed in the middle of the side of the sliding plate 2 near the lower support 12, and the lower mold 4 is installed in the middle of the side of the lower support 12 near the sliding plate 2. The upper mold 3 is located directly above the lower mold 4. Each guide rod 13 passes through the sliding plate 2, and the sliding plate 2 slides towards or away from the lower mold 4 and is installed on the guide rod 13. The driving component 5 is a hydraulic cylinder, which is fixedly installed on the upper support 11. The piston rod of the driving component 5 is connected to the sliding plate 2, so that the sliding plate 2 can be driven to slide, that is, the upper mold 3 is driven to move towards the lower mold 4, and the plate placed on the lower mold 4 is punched.

[0028] like Figure 1 and Figure 2 As shown, an upper mounting plate 31 is fixedly installed on the side of the upper mold 3 near the sliding plate 2, and a pair of upper slide rails 21 are fixedly installed on the side of the sliding plate 2 near the lower mold 4. The upper mounting plate 31 is horizontally slidably installed on the upper slide rails 21, and the sliding plate 2 is equipped with a first locking member 22 for locking the position of the upper mounting plate 31. A pair of lower slide rails 14 are fixedly installed on the side of the lower bracket 12 near the sliding plate 2, and a lower mounting plate 41 is fixedly installed on the side of the lower mold 4 near the lower bracket 12. The lower mounting plate 41 is horizontally slidably installed on the lower slide rails 14, and the mounting bracket 1 is equipped with a second locking member 15 for locking the position of the lower mounting plate 41.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, each of the two lower sliding rails 14 has a sliding groove 141 on its opposite sidewalls near the lower bracket 12. The sliding groove 141 extends horizontally. Sliding strips 411 are integrally formed on both sides of the lower mounting plate 41, extending in the direction of the sliding groove 141. The sliding strips 411 are slidably mounted on the lower sliding rails 14 via the sliding groove 141. The second locking member 15 includes an abutment block 151 and a locking block 152. Both ends of the sliding groove 141 extend outwards into the lower sliding rails 12. Outside the slide rail 14, the abutment block 151 is fixedly installed at one end between the two slide rails 14, and one end of the upper mounting plate 31 abuts against the abutment block 151; the locking block 152 is rotatably installed at the end of the slide rail 14 away from the abutment block 151, and the locking block 152 abuts against the end of the lower mounting plate 41 away from the abutment block 151; by rotating the locking block 152 away from the lower mounting plate 41, the lower mounting plate 41 can be pulled away from the slide rail 14, thus completing the disassembly of the lower mold 4.

[0030] Furthermore, the pivot of the locking block 152 is an adjusting bolt 153, which passes through the locking block 152 and is threaded onto the lower slide rail 14, thereby limiting the rotation position of the locking block 152.

[0031] Furthermore, a handle 42 is installed at the end of the lower mounting plate 41 away from the abutment block 151, so as to facilitate pulling the lower mounting plate 41 away from the lower slide rail 14.

[0032] like Figure 2 As shown, the structure and principle of the first locking member 22 are the same as those of the second locking member 15, and will not be described again here.

[0033] like Figure 1 As shown, each guide rod 13 is fitted with a guide sleeve 16, which is fixedly installed on the sliding plate 2 and slidably installed on the guide rod 13. A limit ring 17 is fixedly installed on the guide rod 13, and the limit ring 17 is arranged opposite to the guide sleeve 16. When the upper mold 3 is in the initial state, the distance between the limit ring 17 and the guide sleeve 16 is the maximum stroke of the upper mold 3.

[0034] The implementation principle of a punching forming machine according to an embodiment of this application is as follows: When it is necessary to replace different upper dies 3 and lower dies 4, the adjusting bolts 153 in the first locking member 22 and the second locking member 15 are rotated respectively to make the locking block 152 leave the upper mounting plate 31 or the lower mounting plate 41. Then, the upper mounting plate 31 and the lower mounting plate 41 are pulled to slide away from the upper slide rail 21 and the lower slide rail 14 respectively, thus completing the disassembly of the upper die 3 and the lower die 4. Then, the appropriate upper die 3 and lower die 4 are slid back to the upper slide rail 21 and the lower slide rail 14. Then, the adjusting bolts 153 in the first locking member 22 and the second locking member 15 are rotated respectively to make the locking block 152 abut against the upper mounting plate 31 or the lower mounting plate 41, thus completing the installation of the new upper die 3 and lower die 4.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
