Description

Technical Field

[0001] Technical Field This invention relates to the field of stamping forming technology, specifically to a stamping forming processing apparatus for the production of metal parts. Background Technology

[0002] Stamping is a common processing method in the production of metal parts. It involves placing metal sheets or strips in a mold using a punch press or press, applying pressure to cause plastic deformation, and thus forming parts of the desired shape.

[0003] Patent publication number CN212070079U relates to an electronic scale panel processing device, including a main frame. A worktable is bolted to the upper side of the main frame, and a support frame is bolted to the upper surface of the worktable. A stamping cylinder is installed at the upper end of the support frame, a guide column is installed inside the support frame, and a lower pressure plate is installed outside the guide column. The piston rod at one end of the stamping cylinder is connected to the lower pressure plate. A telescopic cylinder is installed on the upper side of the lower pressure plate. A sliding groove is opened inside the telescopic cylinder, and a spring is installed at the bottom of the sliding groove. A first sliding plate is slidably connected to one end of the sliding groove, and a clamping column is installed at one end of the telescopic cylinder. This patented device, through the design of the telescopic cylinder, clamping column, spring, and clamping head, allows the clamping head at one end of the clamping column to first press and fix the blank on the lower die when the upper pressure plate drives the lower pressure plate to stamp the blank, before the upper pressure plate stamps and forms the blank.

[0004] In the aforementioned patent, when the upper pressure plate is driven by the lower pressure plate to stamp the blank on the lower die, the pressure head at one end of the pressure column can be pressed on the blank for a certain fixation before the upper pressure plate is used for stamping. However, when stamping metal parts, the workers need to place the metal parts one by one on the stamping machine for stamping. Because some workers will place the metal parts on the stamping machine with their hands in order to improve work efficiency, the stamping machine moves downward and causes danger when the workers' hands are not removed from the bottom of the stamping machine in time. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stamping forming processing apparatus for the production of metal parts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stamping forming processing device for metal parts production, comprising a worktable, a support frame fixedly mounted on the top of the worktable, a driving device fixedly mounted on the top of the support frame, an mounting plate fixedly mounted on the output end of the driving device, and a protective device provided on the mounting plate; wherein, the protective device comprises a mounting frame, a moving plate, a positioning plate, a bending plate, a fixed frame, a contact plate, and a limiting plate, an upper mold mounted on the bottom of the mounting plate, a lower mold mounted on the top of the worktable, the mounting frame fixedly mounted on the top of the mounting plate, the moving plate slidingly penetrating the top of the mounting frame, the positioning plate slidingly penetrating the inner and outer walls of the mounting frame, a slot being formed on the surface of the moving plate, the bending plate fixedly mounted on the surface of the positioning plate, the fixed frame fixedly mounted on the surface of the mounting frame, the contact plate slidingly penetrating the bottom of the fixed frame, and the limiting plate fixedly mounted on the top of the contact plate; when the contact plate moves, it drives the limiting plate to move upward, and when the limiting plate moves upward, it disengages from the bending plate, thereby releasing the limiting plate from restricting the bending plate and the positioning plate.

[0007] According to the above technical solution, a control switch is fixedly installed on the surface of the mounting frame. The control switch is electrically connected to the drive device. When the control switch is pressed, it will control the drive device to stop working, so as to prevent the drive device from forcibly moving the mounting plate downward.

[0008] According to the above technical solution, a reset spring is provided between the positioning plate and the mounting plate, a first spring is provided between the contact plate and the fixed frame, and the limiting plate is in contact with the bending plate. The elastic force of the reset spring will drive the positioning plate to move into the mounting frame.

[0009] According to the above technical solution, the surface of the contact plate is provided with a pushing device for pushing the worker's hand away from the bottom of the mounting plate. The surface of the fixed frame is provided with a limiting device. The pushing device includes a pushing plate, a fixed plate, an L-shaped plate, a sliding plate, a linkage plate, a fixing block, and a positioning plate. When the fixing block moves upward, it pushes the linkage plate and the sliding plate to move. When the sliding plate moves, it pushes the L-shaped plate to move. When the L-shaped plate moves, it disengages from the positioning plate, thus releasing the L-shaped plate from limiting the positioning plate and the pushing plate. The pushing plate is rotatably mounted on the bottom of the contact plate. The fixed plate is fixedly mounted on the surface of the contact plate. The L-shaped plate is slidably mounted on the bottom of the fixed plate. The sliding plate is slidably mounted on the bottom of the fixed plate. The linkage plate is rotatably mounted on the surface of the sliding plate. The fixing block is fixedly mounted on the top of the pushing plate. The positioning plate is fixedly mounted on the top of the pushing plate. A spring is provided between the pushing plate and the contact plate.

[0010] According to the above technical solution, a torsion spring is provided between the linkage plate and the slide plate. The linkage plate is in contact with the fixed block, the positioning plate is in contact with the L-shaped plate, and the slide plate is in contact with the L-shaped plate. The elastic force of the torsion spring will drive the linkage plate to reset, so that the fixed block will push the linkage plate to move.

[0011] According to the above technical solution, the limiting device includes a baffle, an L-shaped block, a Z-shaped plate, an insert plate, an elastic telescopic plate, an inclined plate, and a horizontal plate. When the Z-shaped plate moves upward and contacts the support frame, the support frame pushes the Z-shaped plate downward on the fixed frame. When the Z-shaped plate moves downward, it drives the horizontal plate downward. When the horizontal plate moves downward, it contacts the inclined surface of the inclined plate, causing the horizontal plate to push the inclined plate and the insert plate away from the contact plate. The baffle slides through the contact plate. The L-shaped block is fixedly installed on the top of the baffle. The Z-shaped plate slides on the surface of the fixed frame. The insert plate slides through the inner and outer walls of the fixed frame. The elastic telescopic plate is fixedly installed through the insert plate. The inclined plate is fixedly installed on the top of the elastic telescopic plate. The horizontal plate is fixedly installed on the bottom of the Z-shaped plate. The bottom of the elastic telescopic plate is fixed to the L-shaped block.

[0012] According to the above technical solution, a second spring is provided between the Z-shaped plate and the fixed frame, a third spring is provided between the insert plate and the fixed frame, the baffle is in contact with the push plate, and the elastic force of the second spring will drive the Z-shaped plate to reset.

[0013] According to the above technical solution, the horizontal plate is in contact with the inclined plate, and a No. 4 spring is provided between the baffle and the contact plate so that the horizontal plate will push the inclined plate to move when it moves.

[0014] This invention provides a stamping forming processing apparatus for the production of metal parts. It has the following beneficial effects:

[0015] (1) In this invention, when the drive device moves the mounting plate downward, the mounting plate will move the fixed frame and the contact plate downward. When the contact plate moves downward and contacts the worker's hand, the contact plate will move into the mounting frame. The contact plate will move the limiting plate upward to release the limiting of the locking plate and the bending plate. The locking plate will insert into the slot to limit the moving plate, thereby restricting the mounting plate from continuing to move downward and pressing on the worker's hand, thus improving the safety of the press. At the same time, the movement of the locking plate will squeeze the control switch to shut down the drive device.

[0016] (2) In this invention, since the worker's hands are relatively weak and cannot push the contact plate upward, the worker can easily push the push plate to rotate upward. When the push plate rotates upward, it will push the linkage plate and the slide plate to move. When the slide plate moves, it will push the L-shaped plate to release the limit on the positioning plate and the push plate. Under the action of the spring of the push plate, it will rotate away from the bottom of the mounting plate. When the push plate rotates, it will quickly push the worker's hand away from the bottom of the mounting plate, avoiding the danger caused by the worker's hand not being removed from the bottom of the mounting plate in time.

[0017] (3) In this invention, when the mounting plate rises to the top, the support frame will push the Z-shaped plate to move downward. When the Z-shaped plate moves downward, the horizontal plate will push the inclined plate and the elastic telescopic plate to move. When the elastic telescopic plate moves, it will pull the baffle and the L-shaped block to move. When the baffle moves towards the fixed plate, the baffle will restrict the baffle from rotating upward and be contacted and limited, so as to prevent the worker's hand from accidentally touching the push plate when placing metal parts on the workbench and releasing the limit of the push plate.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Please see Figure 1-4 One embodiment of the present invention is: a stamping forming processing device for producing metal parts, comprising a worktable 1, a support frame 2 fixedly mounted on the top of the worktable 1, a drive device 3 fixedly mounted on the top of the support frame 2, an mounting plate 4 fixedly mounted on the output end of the drive device 3, and a protective device provided on the mounting plate 4; wherein, the protective device includes a mounting frame 5, a moving plate 6, a locking plate 7, a bending plate 8, a fixing frame 9, a contact plate 10, and a limiting plate 11, an upper mold mounted on the bottom of the mounting plate 4, a lower mold provided on the top of the worktable 1, and the mounting frame 5 fixedly mounted on... The top of the mounting plate 4, the movable plate 6 slides through the top of the mounting frame 5, the locking plate 7 slides through the inner and outer walls of the mounting frame 5, the surface of the movable plate 6 has a slot, the bending plate 8 is fixedly installed on the surface of the locking plate 7, the fixed frame 9 is fixedly installed on the surface of the mounting frame 5, the contact plate 10 slides through the bottom of the fixed frame 9, and the limiting plate 11 is fixedly installed on the top of the contact plate 10. The locking plate 7 will insert into the slot to limit the movable plate 6, thereby preventing the mounting plate 4 from continuing to move downward and pressing on the operator's hand, thus improving the safety of the stamping machine.

[0028] A control switch 12 is fixedly installed on the surface of the mounting frame 5. The control switch 12 is electrically connected to the drive device 3. When the control switch 12 is pressed, it will control the drive device 3 to stop working, so as to prevent the drive device 3 from forcibly driving the mounting plate 4 downward.

[0029] A reset spring is provided between the positioning plate 7 and the mounting plate 4, and a first spring is provided between the contact plate 10 and the fixing frame 9. The limiting plate 11 contacts the bending plate 8, and the elastic force of the reset spring will drive the positioning plate 7 to move into the mounting frame 5.

[0030] In this embodiment, during operation: the worker places the metal part on the top of the workbench 1 by hand. Simultaneously, when the worker accidentally controls the drive device 3 to move the mounting plate 4 downward, the downward movement of the mounting plate 4 will cause the fixing frame 9 and the contact plate 10 to move downward. When the contact plate 10 comes into contact with the worker's hand, the worker's hand will push the contact plate 10 to move inward into the fixing frame 9. When the contact plate 10 moves, it will cause the limiting plate 11 to move upward. When the limiting plate 11 moves upward, it will disengage from the bending plate 8, thus releasing the limiting plate 11 from limiting the bending plate 8 and the locking plate 7. The elastic force of the return spring will cause the locking plate 7 to move inward into the mounting frame 5. When the locking plate 7 moves inward into the mounting frame 5, it will insert into the slot and move the moving plate 6. The moving plate 6, the limiting locking plate 7, the mounting frame 5, and the mounting plate 4 move downward to prevent the mounting plate 4 from continuing to move downward and causing danger. When the locking plate 7 moves, it will press the control switch 12, and when the control switch 12 is pressed, it will turn off the drive device 3.

[0031] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, the surface of the contact plate 10 is provided with a pushing device for pushing the worker's hand away from the bottom of the mounting plate 4, and the surface of the fixed frame 9 is provided with a limiting device. The pushing device includes a pushing plate 131, a fixed plate 132, an L-shaped plate 133, a sliding plate 134, a linkage plate 135, a fixing block 136, and a positioning plate 137. When the pushing plate 131 rotates, it will quickly push the worker's hand away from the bottom of the mounting plate 4, avoiding the danger caused by the worker's hand not being removed from the bottom of the mounting plate 4 in time. The pushing plate 131 is rotatably mounted on the bottom of the contact plate 10, the fixed plate 132 is fixedly mounted on the surface of the contact plate 10, the L-shaped plate 133 is slidably mounted on the bottom of the fixed plate 132, the sliding plate 134 is slidably mounted on the bottom of the fixed plate 132, the linkage plate 135 is rotatably mounted on the surface of the sliding plate 134, the fixing block 136 is fixedly mounted on the top of the pushing plate 131, and the positioning plate 137 is fixedly mounted on the top of the pushing plate 131. A spring is provided between the pushing plate 131 and the contact plate 10.

[0032] A torsion spring is provided between the linkage plate 135 and the slide plate 134. The linkage plate 135 contacts the fixing block 136, the positioning plate 137 contacts the L-shaped plate 133, and the slide plate 134 contacts the L-shaped plate 133. The elastic force of the torsion spring will drive the linkage plate 135 to reset, so that the fixing block 136 will push the linkage plate 135 to move.

[0033] The limiting device includes a baffle 141, an L-shaped block 142, a Z-shaped plate 143, an insert plate 144, an elastic telescopic plate 145, an inclined plate 146, and a horizontal plate 147. It prevents the push plate 131 from being accidentally touched by the operator's hand when placing metal parts on the workbench 1, thus releasing the limiting of the push plate 131. The baffle 141 slides through the contact plate 10. The L-shaped block 142 is fixedly installed on the top of the baffle 141. The Z-shaped plate 143 slides on the surface of the fixed frame 9. The insert plate 144 slides through the inner and outer walls of the fixed frame 9. The elastic telescopic plate 145 is fixedly installed through the insert plate 144. The inclined plate 146 is fixedly installed on the top of the elastic telescopic plate 145. The horizontal plate 147 is fixedly installed on the bottom of the Z-shaped plate 143. The bottom of the elastic telescopic plate 145 is fixed to the L-shaped block 142.

[0034] A second spring is provided between the Z-shaped plate 143 and the fixed frame 9, and a third spring is provided between the insert plate 144 and the fixed frame 9. The baffle 141 contacts the push plate 131, and the elastic force of the second spring will drive the Z-shaped plate 143 to reset.

[0035] The horizontal plate 147 contacts the inclined plate 146, and a No. 4 spring is provided between the baffle 141 and the contact plate 10, so that when the horizontal plate 147 moves, it will push the inclined plate 146 to move.

[0036] In this embodiment, when the operator's hand cannot push the contact plate 10 upward, the operator's hand will push the push plate 131 to rotate upward at a certain angle. When the push plate 131 rotates upward, it will drive the fixing block 136 to move upward. When the fixing block 136 moves upward, it will push the linkage plate 135 and the slide plate 134 to move. When the slide plate 134 moves, it will push the L-shaped plate 133 to move. When the L-shaped plate 133 moves, it will disengage from the positioning plate 137, so that the L-shaped plate 133 will release the limitation on the positioning plate 137 and the push plate 131. The elastic force of the spring will drive the push plate 131 to rotate away from the bottom of the mounting plate 4. When the push plate 131 rotates, it will push the operator's hand away from the bottom of the mounting plate 4.

[0037] When the drive device 3 moves the mounting plate 4 upward to the top, the upward movement of the mounting plate 4 will push the Z-shaped plate 143 upward. When the Z-shaped plate 143 moves upward and contacts the support frame 2, the support frame 2 will push the Z-shaped plate 143 downward on the fixed frame 9. When the Z-shaped plate 143 moves downward, it will drive the horizontal plate 147 downward. When the horizontal plate 147 moves downward, it will contact the inclined surface of the inclined plate 146. When the horizontal plate 147 moves downward, it will push the inclined plate 146 and the insert plate 144 to move away from the contact plate 10. When the insert plate 144 moves, it will drive the elastic telescopic plate 145 to move. When the elastic telescopic plate 145 moves, it will drive the L-shaped block 142 and the baffle 141 to move. When the baffle 141 moves, it will restrict the upward rotation of the push plate 131, preventing the push plate 131 from rotating upward when the staff puts materials.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
