Technical Field
[0001] The utility model relates to the technical field of hardware stamping part production, in particular to a raw material screening machine for hardware stamping part production. Background Technique
[0002] Hardware stamping parts are a common processing method in the field of hardware processing. It refers to using metal flat raw materials at room temperature, through the pressure of a mold and a press, to make the material bend and form, so as to obtain parts with a specified shape. Hardware stamping parts are widely used in various industries, such as the automotive, electronics, household appliances, daily necessities and other fields.
[0003] In order to ensure the quality of the finished hardware stamping parts, before stamping production, generally, the metal raw material plate of the hardware parts to be stamped is screened for resistance to bending and cracking, so as to ensure that there will be no crack gaps in the bent parts of the products formed by stamping and bending in the later stage. Therefore, a screening device for the metal raw material plate of the hardware parts to be stamped is required.
[0004] At present, for the existing screening device for the metal raw material plate of the hardware parts to be stamped, when the screening pressing plate on the screening cylinder performs screening stamping on the metal raw material plate for resistance to bending and cracking, if the current metal raw material plate has weak resistance to bending and cracking, the metal raw material plate may break and fly, and the flying metal raw material plate may directly hit the operator's face or body, resulting in a dangerous situation of injury.
[0005] In addition, if the screening pressing plate directly penetrates the metal raw material plate of the hardware parts to be stamped during the screening stamping for resistance to bending and cracking, the slag at the penetrated part of the metal raw material plate of the hardware parts to be stamped will directly fall to the ground, and the operator still needs to bend down to pick up the slag, which is rather troublesome. Content of the Utility Model
[0006] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose a raw material screening machine for hardware stamping part production.
[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0008] Design a raw material screening machine for hardware stamping part production, including a screening press table, a bracket and a clamping cylinder are arranged on the screening press table, a pressing plate is arranged on the clamping cylinder, a screening cylinder is arranged on the bracket, a screening pressing plate is arranged on the screening cylinder, a guide rod and a switch are arranged on the screening press table;
[0009] A motor is arranged on the screening press table, a screw rod is arranged on the motor, a protective baffle is arranged above the screening press table, and a first connecting block and a second connecting block are arranged on the protective baffle;
[0010] A slag dropping opening is formed in the screening pressing table. A working inner groove and supporting legs are provided on the screening pressing table. Guide rails are provided on the supporting legs, and a slag receiving box is arranged on the guide rails. A slag receiving cavity and a limiting plate are provided on the slag receiving box.
[0011] Further, the first connecting block is in threaded connection with the screw rod, and the second connecting block is slidably sleeved on the guide rod.
[0012] Further, vertical ribs and horizontal ribs are provided on the first connecting block. There are two horizontally symmetrical horizontal ribs. Both the vertical ribs and the horizontal ribs are triangular plate structures.
[0013] Further, the working inner groove is opened at the front end of the screening pressing table, and the top view cross-section of the working inner groove is a U-shaped inner groove structure.
[0014] Further, there are four symmetrically arranged supporting legs, and there are two symmetrically arranged left and right guide rails which are in sliding contact with the slag receiving box.
[0015] Further, the back end face of the limiting plate is in contact with the supporting leg. Buckling grooves are formed on the limiting plate. There are two horizontally symmetrical buckling grooves, and the top view cross-section of the buckling grooves is an arc-shaped inner groove.
[0016] Further, a sealing slot is opened on the screening pressing table, and the top view cross-section size of the protection baffle is not larger than the inner groove size of the top view cross-section of the sealing slot.
[0017] A raw material screening machine for the production of hardware stamping parts proposed by the present utility model has the following beneficial effects:
[0018] 1. By arranging an electrically controlled vertically guided and movable protection baffle on the screening pressing table, the front end of the screening pressing table can be blocked. When the screening pressing plate on the screening cylinder performs screening stamping on the metal raw material plate for bending resistance and cracking resistance, if the bending resistance and cracking resistance performance of the current metal raw material plate is weak, the metal raw material plate may break and fly. The flying metal raw material plate can be blocked by the transparent protection baffle, thereby avoiding the situation of directly hitting the operator's face or body and causing injury.
[0019] 2. By arranging a slidable slag receiving box guided under the screening pressing table, when performing screening stamping for bending resistance and cracking resistance, if the screening pressing plate directly penetrates the metal raw material plate of the hardware part to be stamped, the slag at the penetrated part will directly fall into the slag receiving box. When the slag receiving box is full, the slag receiving box can be slid out for cleaning, which is very convenient and avoids the operator having to bend down to pick it up on the ground.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0027] Referring to Figures 1 - 5 , a raw material screening machine for the production of hardware stamping parts, including a screening pressing table 1, a bracket 3 and a clamping cylinder 13 are provided on the screening pressing table 1, a pressing plate 14 is provided on the clamping cylinder 13, a screening cylinder 31 is provided on the bracket 3, a screening pressing plate 32 is provided on the screening cylinder 31, a guide rod 15 and a switch 12 are provided on the screening pressing table 1;
[0028] A motor 2 is provided on the screening pressing table 1, a screw rod 21 is provided on the motor 2, a baffle plate 4 is provided above the screening pressing table 1, and a first connecting block 41 and a second connecting block 42 are provided on the baffle plate 4;
[0029] A slag dropping opening 11 is opened on the screening pressing table 1, a working inner groove 16 and legs 7 are provided on the screening pressing table 1, a guide rail 71 is provided on the legs 7, a slag receiving box 5 is provided on the guide rail 71, a slag receiving cavity 51 and a limiting plate 6 are provided on the slag receiving box 5. The baffle plate 4 body is made of Pam armor plate material, the body is transparent, and it has excellent impact resistance and abrasion resistance.
[0030] Three buttons are preset on the switch 12 to respectively realize the forward and reverse rotation of the motor shaft of the motor 3 and stop in real time.
[0031] The first connecting block 41 is threadedly connected to the screw rod 21, and the second connecting block 42 is slidably sleeved on the guide rod 15. When the screw rod 21 rotates, the threaded drive drives the guard plate 4 to slide vertically along the guide rod 15 through the second connecting block 42, playing a role of vertical guiding.
[0032] The first connecting block 41 is provided with a vertical rib plate 43 and a horizontal rib plate 44. The horizontal rib plates 44 are two that are symmetrically arranged front and back. Both the vertical rib plate 43 and the horizontal rib plate 44 are triangular plate structures, overall improving the structural stability between the guard plate 4 and the first connecting block 41 and the second connecting block 42 respectively.
[0033] The working inner groove 16 is opened at the front end of the screening pressing table 1. The top view cross-section of the working inner groove 16 is a U-shaped inner groove structure, which facilitates the operator's body to enter the working inner groove 16, and then enables the operator to approach the pressing plate 14 part, further facilitating the close inspection of the screening operation process.
[0034] The supporting legs 7 are four that are symmetrically arranged. The guide rails 71 are two that are symmetrically arranged left and right and are in sliding contact with the slag receiving box 5, achieving the effect of guiding the sliding of the slag receiving box 5.
[0035] The back end face of the limiting plate 6 is in contact with the supporting leg 7. The limiting plate 6 can prevent the slag receiving box 5 from sliding inward between the two supporting legs 7.
[0036] An artificial magnet is preset on the back end face of the limiting plate 6, which can be magnetically adsorbed and positioned with the supporting leg 7 made of metal material.
[0037] The limiting plate 6 is provided with buckling grooves 61. The buckling grooves 61 are two that are symmetrically arranged left and right and the top view cross-section is an arc-shaped inner groove, which can realize the finger digging into the buckling grooves 61 and conveniently pulling the slag receiving box 5.
[0038] The screening pressing table 1 is provided with sealing slots 10. The top view cross-section size of the guard plate 4 is not greater than the inner groove size of the top view cross-section of the sealing slots 10, ensuring that the lower end face of the guard plate 4 can be smoothly inserted into the sealing slots 10.
[0039] Working mode: First, place the metal raw material plate to be screened on the screening press table 1, then start the clamping cylinder 13 to drive the pressure plate 14 to move downward and firmly press the metal raw material plate. Next, start the motor 2 through the switch 12, drive the screw rod 21 to rotate clockwise, and through the thread transmission with the first connecting block 41, drive the first connecting block 41 and the guard plate 4 to move downward as a whole. When the lower end of the guard plate 4 is inserted into the sealing slot 10, stop the motor 2 and start the screening cylinder 31 to drive the screening pressure plate 32 to move downward quickly. The screening pressure plate 32 will perform a bending and cracking resistance screening stamping on the lower metal raw material plate. If there are no cracks in the current metal raw material plate, the metal raw material plate with good quality can be screened out. If cracks appear, it cannot be used. At the same time, if the bending and cracking resistance performance of the current metal raw material plate is weak, the metal raw material plate may break and fly. At this time, the flying metal raw material plate can be blocked by the transparent guard plate 4, thus avoiding the risk of injury caused by directly hitting the operator's face or body.
[0040] In addition, when performing the bending and cracking resistance screening stamping, if the screening pressure plate 32 directly penetrates the metal raw material plate of the hardware part to be stamped, the slag at the penetrated part will directly fall into the slag receiving box 5 through the slag falling port 11. When the slag receiving box 5 is full, insert your finger into the buckle groove 61 and pull forward, then the slag receiving box 5 can be driven to slide out along the guide rail 71. Then, the slag in the slag receiving cavity 51 can be cleaned, which is very convenient and avoids the operator having to bend down to pick it up on the ground.
