Description

Technical Field

[0001] The present application relates to the technical field of punch press protection, and in particular to a punch press protection device. Background Art

[0002] Punching machines, also known as stamping presses, are common equipment in metal processing. Punching machines are widely used in electronics, communications, computers, home appliances, furniture, transportation, (automobiles, motorcycles, bicycles) hardware parts and other fields.

[0003] A punch press generally includes a workbench and a punch block. When punching a workpiece, the workpiece to be punched is generally placed on the workbench, and the punch block is moved toward the workpiece, and a certain force is applied to the workpiece such as a sheet metal part by the punch block to deform the workpiece such as a sheet metal part.

[0004] At present, when a punch block punches a sheet metal part or other workpiece, part of the sheet metal part or other workpiece is easily broken off by the impact force of the punch block, and there is a defect that the broken off debris affects the personal safety of the staff near the punch press.

[0035] The following combination Figure 1-Figure 3 This application is described in further detail.

[0036] The embodiment of the present application discloses a punch press protection device.

[0037] A punch press protection device comprises a workbench 1, a mounting seat 2, a telescopic protection part 3 and an adjustment part 4. The mounting seat 2 is mounted on the top of the workbench 1 near the workpiece, the telescopic protection part 3 and the adjustment part 4 are mounted on the mounting seat 2, and the telescopic protection part 3 and the mounting seat 2 are slidably matched. The telescopic protection part 3 is used to block the flying debris, and the adjustment part 4 is used to adjust the overall height of the telescopic protection part 3 according to the needs of the protection range.

[0038] When stamping the workpiece, the overall height of the telescopic guard 3 is adjusted through the adjustment part 4 according to the range to be protected. At the same time, according to the position to be protected by the staff, the telescopic guard 3 and the mounting seat 2 are relatively rotated, so as to facilitate the adjustment of the protection position of the telescopic guard 3 and improve the convenience of protecting the flying debris.

[0039] The mounting seat 2 includes a base 21 and a limiting plate 22 .

[0040] The base 21 is in a rectangular shape, and a mounting plate 211 is fixedly connected to the bottom of the base 21 . When the base 21 is installed, the mounting plate 211 and the workbench 1 are fixedly connected by bolts, so as to improve the convenience of placing the base 21 .

[0041] A mounting groove 212 is formed on the top of the base 21 . The mounting groove 212 is an arc-shaped groove and runs through both sides of the base 21 in the length direction.

[0042] The limiting plate 22 is horizontally arranged on the top of the base 21, and the limiting plate 22 covers the mounting groove 212, and the limiting plate 22 is fixedly connected to the base 21 by bolts. An elastic pad 221 is arranged at the bottom of the limiting plate 22, and the elastic pad 221 is located inside the mounting groove 212, and the top of the elastic pad 221 is fixedly connected to the bottom of the limiting plate 22. In the embodiment of the present application, the top of the elastic pad 221 and the bottom of the limiting plate 22 are bonded.

[0043] The telescopic protection part 3 includes a placement ring 31 and a protection plate 32 .

[0044] The placement ring 31 is placed horizontally, and part of the placement ring 31 is located inside the installation groove 212. The bottom of the placement ring 31 contacts the bottom of the installation groove 212, and the top of the placement ring 31 contacts the elastic pad 221. The placement ring 31 and the installation groove 212 are slidably matched, and the center of the placement ring 31 and the arc center of the arc-shaped installation groove 212 coincide with each other.

[0045] There are a plurality of protective plates 32, which are all mounted on the top of the placement ring 31, and are distributed in the vertical direction. In the embodiment of the present application, there are three protective plates 32. Each protective plate 32 is an arc plate, and the arc center of each protective plate 32 coincides with the axis of the placement ring 31.

[0046] A sliding groove 321 is formed on the top of each protective plate 32. The protective plate 32 located above two adjacent protective plates 32 in the vertical direction is placed inside the sliding groove 321 of the protective plate 32 located below, and the protective plates 32 slide and cooperate with the corresponding sliding groove 321. By sliding two adjacent protective plates 32 in the vertical direction, the overall height of the telescopic protective part 3 is changed, thereby adjusting the protective range of the telescopic protective part 3.

[0047] In order to reduce the situation that two adjacent protective plates 32 are separated from each other during the movement, a guide groove 322 is opened on the side wall of each protective plate 32 along the height direction of the protective plate 32, and a guide rod 323 is threadedly connected to the side wall of the protective plate 32 located above the two adjacent protective plates 32 in the vertical direction, and the guide rod 323 and the guide groove 322 of the protective plate 32 located below the two adjacent protective plates 32 in the vertical direction are slidably matched. The inner wall of the guide groove 322 limits the position of the two adjacent protective plates 32 through the guide rod 323.

[0048] At the same time, in order to facilitate the sliding of two adjacent protective plates 32, a handle 324 is fixedly connected to the side wall of the uppermost protective plate 32 in the vertical direction. The staff uses the handle 324 to slide between the two adjacent protective plates 32, thereby improving the convenience of adjusting the overall height of the telescopic protective part 3.

[0049] The adjustment portion 4 includes an adjustment rod 41 , an adjustment ring 42 and a positioning rod 43 .

[0050] The adjusting rod 41 is vertically arranged at a position on the top of the placing ring 31 close to the protective plate 32 , and the bottom of the adjusting rod 41 is fixedly connected to the bottom of the placing ring 31 .

[0051] The adjusting ring 42 is slidably sleeved on the outer periphery of the adjusting rod 41 , and the outer wall of the adjusting ring 42 is fixedly connected to the uppermost protection plate 32 in the vertical direction.

[0052] To facilitate the rotation of the positioning rod 43 , one end of the positioning rod 43 is fixedly connected to a rotating cap, an adjusting ring 42 is spirally passed through the end of the positioning rod 43 away from the rotating cap, and the end of the positioning rod 43 away from the rotating cap is used to contact the adjusting rod 41 .

[0053] When the protective plate 32 located at the top in the vertical direction moves, the protective plate 32 drives the adjustment ring 42 to move on the adjustment rod 41. After the protective plate 32 moves to the set position, the positioning rod 43 is rotated by rotating the cap, and the end of the positioning rod 43 is pressed against the adjustment rod 41, thereby fixing the protective plate 32 located at the top in the vertical direction.

[0054] The implementation principle of a punch press protection device in an embodiment of the present application is as follows: the base 21 is fixedly mounted on the workbench 1 through the mounting plate 211, and the placement ring 31 is partially placed inside the mounting groove 212, and the placement ring 31 is limited by the elastic pad 221 on the limiting plate 22. When protection is required, the staff moves the topmost protection plate 32 in the vertical direction in the vertical direction through the handle 324, and after the topmost protection plate 32 in the vertical direction moves to the set position, the topmost protection plate 32 is fixed by pressing the end of the positioning rod 43 against the adjusting rod 41. Then, the placement ring 31 can be rotated according to the position that the staff needs to protect. When protection is not required, the positioning rod 43 and the adjusting rod 41 can be disconnected.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
