[0026] Beneficial Effects The present invention provides a punching device for elevator parts. Compared with the prior art, it has the following beneficial effects: (1) The stamping equipment for elevator accessories uses an electric push rod to push the clamping plate and the anti-skid pad to fix the raw material, and the hydraulic cylinder pushes the moving seat and the upper die to move downward and enter the lower die to stamp the raw material for the accessories. After the stamping is completed, the electric push rod retracts the clamping plate and the anti-skid pad away from the accessories, and the clamping plate drives the connecting block to slide in the through slot, and the connecting block drives the lower rack and the lower slider to slide in the inner wall of the lower slide slot, and drives the transmission gear to rotate, and the upper rack meshing with the transmission gear is driven to move in the mounting frame, and the upper rack drives the upper slider to slide in the upper slide slot and approach the lower die, and the upper rack drives the trapezoidal seat to enter the material removal slot to push the accessories out of the lower die, so that when the elevator accessories are stamped, the raw material can be clamped and fixed, and the problem of accessory deviation caused by position offset during stamping is prevented, thereby improving the working stability of the stamping process, and when it is out of the clamping state, it will drive the stamped accessories to be lifted and demolded, which can facilitate the staff to take the material.

[0027] (2) The stamping equipment for elevator accessories slides forward along the outer wall of the electric slide rail through the electric slider. After the clamping seat and the rubber pad are close to the accessories, the servo motor drives the bidirectional screw to rotate, and the sliding seat moves close to each other in the inner wall of the movable frame along the outer wall of the bidirectional screw. The sliding seat drives the movable frame, the limit plate, the clamping seat and the rubber pad to move. The clamping seat and the rubber pad clamp and fix the processed accessories. When the clamping seat and the rubber pad are subjected to force, the limit plate will slide in the inner wall of the limit groove and compress the spring. The electric slider slides backward along the outer wall of the electric slide rail, and the clamped and fixed accessories are separated from the lower mold and move backward. When the elevator accessories are processed, the demolded accessories can be clamped and taken out without the need for the staff to reach deep into the lower mold to take the material, thereby reducing the possibility of safety hazards and protecting the staff.

[0028] (3) The stamping equipment for elevator parts places the raw materials for processing the parts on the electric feeding roller on the top wall of the feed seat, and drives the raw materials for processing the parts through the guide plate to the top wall of the lower die through the conveyance of the electric feeding roller, and fits with the inner wall of the C-shaped baffle plate. When processing the elevator parts, the staff can place the raw materials on the electric feeding roller, and complete the automatic loading without directly placing the raw materials on the top wall of the lower die, thereby improving the working safety of the entire device.

[0036] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] During operation, firstly, the electric slide rail 42, the electric slider 43, the servo motor 46, the electric feeding roller 53, the electric push rod 63 and the hydraulic cylinder 12 are connected through the external power supply and the controller 2, and the parts processing raw materials are placed on the electric feeding roller 53 on the top wall of the feed seat 51. The parts processing raw materials are driven by the electric feeding roller 53 to pass through the guide plate 54 and enter the top wall of the lower mold 3, and fit with the inner wall of the C-shaped baffle plate 68. Then, the electric push rod 63 installed on the connecting seat 62 pushes the clamping plate 64 and the anti-skid pad 65 to approach the parts processing raw materials on the top wall of the lower mold 3. The clamping plate 64 and the anti-skid pad 65 are clamped and fixed by the mutual cooperation of the clamping plate 64 and the anti-skid pad 65. When the clamping plate 64 moves, it will drive the connecting block 615 to pass through the wear plate 64. The lower rack 611 slides in the inner wall of the slot 66, and then the connecting block 615 drives the lower rack 611 to slide in the inner wall of the mounting frame 61, and the lower rack 611 synchronously drives the lower slider 614 to slide in the inner wall of the corresponding lower slide groove 617, so that the lower rack 611 slides in the mounting frame 61 close to the lower mold 3, and drives the transmission gear 69 to rotate, and the upper rack 610 meshing with the transmission gear 69 is driven to move in the mounting frame 61, and the upper rack 610 drives the upper slider 612 to slide in the inner wall of the upper slide groove 616 and away from the lower mold 3, and the upper rack 610 synchronously drives the trapezoidal seat 613 away from the position of the material starting chute 67. After the clamping plate 64 and the anti-slip pad 65 complete the clamping and fixing of the accessory processing raw materials, the hydraulic cylinder 12 pushes the moving seat 8 and the upper The upper die 7 moves downward, and when the movable seat 8 moves, it will drive the positioning rod 11 to move downward to prevent it from shifting in position. When the upper die 7 continues to move downward, it enters the lower die 3 to stamp the raw materials for processing the accessories. When the stamping is completed, the movable end of the hydraulic cylinder 12 contracts to drive the movable seat 8 and the upper die 7 to move upward. When the upper die 7 moves upward, it separates from the lower die 3. Then the movable end of the electric push rod 63 contracts the clamping plate 64 and the anti-slip pad 65 away from the accessories on the top wall of the lower die 3. When the clamping plate 64 moves, it will drive the connecting block 615 to slide in the inner wall of the through slot 66, and then the connecting block 615 drives the lower rack 611 to slide in the inner wall of the mounting frame 61, and the lower rack 611 synchronously drives the lower slider 614 to the corresponding lower The lower rack 611 slides in the inner wall of the slide groove 617, so that the lower rack 611 slides in the mounting frame 61 away from the lower mold 3, and drives the transmission gear 69 to rotate, and the upper rack 610 meshing with the transmission gear 69 is driven to move in the mounting frame 61, and the upper rack 610 drives the upper slider 612 to slide in the inner wall of the upper slide groove 616 and approach the lower mold 3. After the upper rack 610 drives the trapezoidal seat 613 to enter the material starting chute 67, since the trapezoidal seat 613 is trapezoidal and the trapezoidal seat 613 contacts the accessory, when the trapezoidal seat 613 slides toward the inner wall of the material starting chute 67, the accessory is pushed higher from the lower mold 3 under the action of the trapezoidal seat 613.

After the clamping seat 412 and the rubber pad 413 are close to the processed accessories, the bidirectional screw rod 45 is driven to rotate by the servo motor 46. When the bidirectional screw rod 45 rotates, it drives the sliding seat 47 to move along the outer wall of the bidirectional screw rod 45 in the inner wall of the moving frame 44. The sliding seat 47 also drives the movable frame 48, the limit plate 411, the clamping seat 412 and the rubber pad 413 to move. The clamping seat 412 and the rubber pad 413 are 13 clamps and fixes the processed accessories. When the clamping seat 412 and the rubber pad 413 are clamped and subjected to force, the limit plate 411 will slide in the inner wall of the limit groove 49 and compress the spring 410 to prevent the large clamping force from causing deformation of the accessories. The electric slider 43 slides backward along the outer wall of the electric slide rail 42. The electric slider 43 drives the moving frame 44, the two-way screw rod 45, the sliding seat 47, the movable frame 48, the clamping seat 412 and the rubber pad 413 as well as the clamped and fixed accessories to move backward from the lower mold 3. After the accessories are sent away, it is convenient for the staff to take them.
