[0027] Example 1

[0028] Reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, and this embodiment provides a precision punching machine capable of automatic feeding. The precision punching machine capable of automatic feeding includes a main body component 100 and a feeding component 200, which can automatically place metal sheets on the surface of the punching machine workbench.

[0029] The main assembly 100 includes a punch press 101 , a workbench 102 and a support leg 103 . The workbench 102 is fixed to one side of the punch press 101 , and the support leg 103 is fixed to the bottom of the punch press 101 .

[0030] The punch press 101 is a mechanical device used for metal processing, mainly used for stamping metal sheets. The punch press 101 is provided with a punch. The metal sheet is placed on a workbench and then pressure is applied to perform a stamping operation to stamp the metal sheet according to the shape. The workbench 102 is a platform for supporting the metal sheet. The workbench 102 is usually made of a solid metal material and can withstand the pressure and force applied by the punch press 101. During the operation of the punch press 101, the metal sheet is placed on the workbench 102, and pressure is applied by the punch on the punch press 101 to complete the stamping of the metal sheet. There are four support legs 103, which are respectively fixed at the four corners of the bottom of the punch press 101. The support legs 103 can be set to support the punch press 101 to prevent the punch press 101 from shifting.

[0031] The feeding assembly 200 is disposed on the punching machine 101 , and includes a feeding member 201 , a clamping member 202 and a transmission member 203 . The feeding member 201 is disposed on the punching machine 101 , the clamping member 202 is located on the workbench 102 , and the transmission member 203 is disposed on the clamping member 202 .

[0032] The feeding member 201 can be used to automatically place the metal sheet on the surface of the workbench 102 of the punch press 101 without manual loading, so that the metal sheet can be quickly placed on the workbench 102, avoiding the waiting time for manual loading, thereby improving production efficiency. There are two groups of clamping members 202, both of which are located on the workbench 102. After the metal sheet is placed on the surface of the workbench 102 of the punch press 101, the clamping member 202 can be used to straighten the metal sheet to prevent it from shifting. After the feeding member 201 transports the metal sheet to the surface of the workbench 102, the feeding member 201 will return to its original position to transport the next metal sheet. When the feeding member 201 returns to its original position, the transmission member 203 can be used to drive the clamping member 202 to move, so that the clamping member 202 straightens the metal sheet. At the same time, the punch of the punch press 101 will apply pressure to the metal sheet to punch the metal sheet, thereby reciprocatingly processing the metal sheet, without the need for manual loading, improving work efficiency.

[0033] Example 2

[0034] Reference Figure 1 to Figure 5 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, the feeding member 201 includes a material storage frame 201a and a positioning block 201b. The material storage frame 201a is located in the punching machine 101, and the positioning block 201b is fixed to one side of the material storage frame 201a.

[0036] The material storage frame 201a is provided to store metal sheets. A door is provided on one side of the punch press 101 to facilitate the user to place the metal sheets in the material storage frame 201a for processing the metal sheets. There are two positioning blocks 201b, both of which are fixed to the inner wall of the punch press 101. The positioning blocks 201b can be provided to support the material storage frame 201a to prevent the material storage frame 201a from shifting.

[0037] Specifically, the feeding member 201 further includes a pushing plate 201c, a sliding frame 201d and a sliding block 201e. The pushing plate 201c is arranged at the bottom of the material storage frame 201a, the sliding frame 201d is fixed to one side of the pushing plate 201c, and the sliding block 201e is fixed to the inner wall of the punching machine 101.

[0038] After the metal sheet is placed in the storage frame 201a, the first metal sheet will fall into the storage slot of the push plate 201c. When the metal sheet in the storage frame 201a needs to be transported to the workbench 102, the movement of the push plate 201c can drive the metal sheet to move, so that the metal sheet is moved to the workbench 102, so that the metal sheet can be processed. There are two slide frames 201d, which are respectively fixed on both sides of the push plate 201c. There are two sliders 201e, which are both fixed on the inner wall of the punch press 101. A slide groove is opened on one side of the slide frame 201d, and the slider 201e slides in the slide groove. When the push plate 201c moves, it can drive the slide frame 201d to move. At this time, the slide groove will slide on the slider 201e, so that the push plate 201c can be supported to prevent the push plate 201c from deviating.

[0039] Specifically, the feeding member 201 also includes a push block 201f, a support bar 201g and a torsion spring 201h. The support bar 201g is fixed to the inner wall of the material storage frame 201a, and the push block 201f is sleeved on the outside of the support bar 201g. The push block 201f and the support bar 201g are movably connected. One end of the torsion spring 201h is fixed to one side of the push block 201f, and the other end is fixed to one side of the support bar 201g.

[0040] There are two support bars 201g, both fixed to the inner wall of the material storage frame 201a, there are two push blocks 201f, both sleeved on the outside of the support bar 201g, there are two torsion springs 201h, both fixed to one side of the push block 201f, the push plate 201c drives the metal sheet to move when it moves, and the metal sheet drives the push block 201f to rotate, and the push block 201f can apply a torsional force to the torsion spring 201h when it rotates, and a leakage groove is provided on one side of the push plate 201c, and when the push plate 201c moves, it drives the metal sheet to move and separate from the push block 201f, at which time the push block 201f will contact the leakage groove, and then the torsion spring 201h is pressed against the push block 201f. 01h The rotational force will drive the push block 201f to return to its original position, and at this time the push plate 201c also returns to its original position. When the push plate 201c returns to its original position, the push block 201f will only move in one direction due to the setting of the material storage frame 201a. When the push plate 201c returns to its original position, it will drive the metal sheet to return to its original position. At this time, the setting of the push block 201f will squeeze the metal sheet and separate the metal sheet from the push plate 201c, so that the metal sheet can fall onto the workbench 102, and then the metal sheet can be stamped. The support bar 201g is used to support the push block 201f to prevent the push block 201f from shifting.

[0041] Specifically, the feeding member 201 further includes a cylinder 201i and a positioning plate 201j. The cylinder 201i is fixed to one side of the pushing plate 201c, and the positioning plate 201j is sleeved on the outer side of the cylinder 201i.

[0042] The cylinder 201i is used to drive the push plate 201c to move. After the push plate 201c conveys the metal sheet to the workbench 102, the push plate 201c will return to the initial position, and the cylinder 201i will stop moving. After the punch completes the punching of the metal sheet, the cylinder 201i will continue to move. The pause of the cylinder 201i belongs to the prior art, so it will not be elaborated in detail. The positioning plate 201j is fixed to the inner wall of the punch press 101. The positioning plate 201j can be set to support the cylinder 201i to prevent the cylinder 201i from shifting.

[0043] Specifically, the clamping member 202 includes a clamping plate 202a and a threaded rod 202b. The clamping plate 202a is disposed on the top of the workbench 102. The threaded rod 202b is plugged into one side of the clamping plate 202a. The threaded rod 202b and the clamping plate 202a are threadedly connected.

[0044] The threads on the two threaded rods 202b are arranged in opposite directions. After the metal sheet is conveyed to the workbench 102, the push plate 201c will continue to move to the initial position. While the push plate 201c moves, the threaded rod 202b can be rotated. The rotation of the threaded rod 202b can drive the other threaded rod 202b to rotate. The rotation of the two threaded rods 202b can drive the clamping plate 202a to move towards each other. The clamping plate 202a moves to clamp the metal sheet. At this time, the set cylinder 201i will pause, and then the punch on the punch press 101 will be pressed down, so that the metal sheet can be punched. After the punching is completed, the metal sheet is taken out.

[0045] Specifically, the clamping member 202 further includes a moving block 202 c and a positioning frame 202 d . The moving block 202 c is fixed to one end of the clamping plate 202 a , and the positioning frame 202 d is fixed to the top of the workbench 102 .

[0046] A moving groove is provided on the positioning frame 202d. When the clamping plate 202a moves, the moving block 202c moves in the moving groove, thereby supporting the clamping plate 202a and preventing the clamping plate 202a from deviating when moving.

[0047] Example 3

[0048] Reference Figure 2 to Figure 5 , which is the third embodiment of the utility model, and is based on the first two embodiments. Specifically, the clamping member 202 further includes a fixed plate 202e and a rotating roller 202f, the fixed plate 202e is rotatably connected to one end of the threaded rod 202b through a bearing, and the rotating roller 202f is sleeved on the outer side of the threaded rod 202b.

[0049] The fixed plate 202e is fixed to the top of the punch press 101. The fixed plate 202e can support the threaded rod 202b to prevent the threaded rod 202b from deviating. A sliding plate is arranged on the surface of the rotating roller 202f. When the metal sheet is separated from the push plate 201c, the rotating roller 202f can guide the metal sheet by rotating so that the metal sheet falls onto the workbench. Due to the sliding plate arranged on the surface of the rotating roller 202f, when the metal sheet is separated from the push plate 201c, the metal sheet is inclined, the sliding plate has no friction, and the rotation only guides the metal sheet so that the metal sheet can slide onto the workbench.

[0050] Specifically, the transmission member 203 includes a first pulley 203a, a belt 203b and a second pulley 203c. The first pulley 203a is sleeved on the outside of the threaded rod 202b, the belt 203b is sleeved on the outside of the first pulley 203a, and the second pulley 203c is located inside the belt 203b.

[0051] The first pulley 203a is fixed to one side of the rotating roller 202f. When the push plate 201c moves, it can drive the second pulley 203c to rotate, and the second pulley 203c drives the belt 203b to rotate. At this time, the rotation of the belt 203b can drive the first pulley 203a to rotate, and the rotation of the first pulley 203a can drive the two threaded rods 202b to rotate.

[0052] Specifically, the transmission member 203 also includes a gear 203d, a rack 203e and a support shaft 203f. The gear 203d is fixed to one side of the second pulley 203c, the rack 203e is arranged on the top of the gear 203d, the rack 203e and the gear 203d are meshed, the support shaft 203f is inserted into one side of the gear 203d, and the support shaft 203f and the gear 203d are movably connected.

[0053] The rack 203e is fixed to the bottom of the push plate 201c. When the push plate 201c moves, the rack 203e can be driven to move. The movement of the rack 203e can drive the gear 203d to rotate. At this time, the rotation of the gear 203d can drive the second pulley 203c to rotate. The support shaft 203f is fixed to the inner wall of the punch press 101, and the support shaft 203f is inserted into one side of the second pulley 203c. The support shaft 203f is movably connected to the second pulley 203c. The second pulley 203c and the gear 203d can be supported by the setting of the support shaft 203f to prevent the gear 203d from deflecting.

[0054] During use, when it is necessary to process the metal sheet, first open the door on one side of the punch press 101, and place the metal sheet in the storage frame 201a. After the metal sheet is placed in the storage frame 201a, the first metal sheet will fall onto the push plate 201c. When it is necessary to transport the metal sheet in the storage frame 201a to the workbench 102, start the cylinder 201i, and the cylinder 201i will drive the push plate 201c to move. When the push plate 201c moves, it drives the metal sheet to move. The metal sheet will drive the push block 201f to rotate, and the push block 201f can rotate to the torsion bar. The spring 201h applies a torsional force, and when the push plate 201c moves, it drives the metal sheet to move until it is separated from the push block 201f. At this time, the push block 201f will contact the leakage groove, and then the rotation force of the torsion spring 201h will drive the push block 201f to return to its original position. At this time, the push plate 201c also returns to its original position. When the push plate 201c returns to its original position, it drives the metal sheet to return to its original position. At this time, the setting of the push block 201f will squeeze the metal sheet, so that the metal sheet is separated from the push plate 201c, so that the metal sheet can fall onto the workbench 102.

[0055] After the push plate 201c returns to its original position and drops the metal sheet onto the workbench 102, the push plate 201c will continue to move. When the push plate 201c moves, it can drive the rack 203e to move. The movement of the rack 203e can drive the gear 203d to rotate. The rotation of the gear 203d can drive the second pulley 203c to rotate. The second pulley 203c drives the belt 203b to rotate. The rotation of the belt 203b can drive the first pulley 203a to rotate. The rotation of the first pulley 203a can drive the two threaded rods 202b to rotate. The threads arranged on the two threaded rods 202b are in opposite directions. The rotation of the two threaded rods 202b can drive the clamping plate 202a to move towards each other. The movement of the clamping plate 202a can straighten the metal sheet. At this time, the cylinder 201i will pause, and then the punch on the punch press 101 will be pressed down, so that the metal sheet can be stamped. After the stamping is completed, the metal sheet can be taken out.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
