Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of nut stamping, and particularly relates to a stamping device for large fasteners. BACKGROUND

[0002] The nut stamping process is a precise manufacturing method for processing metal bars into nuts through a die and a punch press. The material of the nut is generally metal, and the inner wall is engraved with a concave-convex groove called a thread. The nut is usually used in cooperation with a screw.

[0003] The main raw material for producing nuts is generally a steel bar. The steel bar is cut into the required length by a sawing machine, and after being heated, is sent to a stamping table so that the stamping bar is vertically placed on the stamping table. Then, the head of the steel bar is stamped by a stamping device to form the required shape.

[0004] During the cutting of the steel bar, the cutter needs to work continuously, which can easily cause the cutter to deviate, resulting in an uneven cutting surface of the stamping bar. For example, the cutting surface is inclined. The inclination can cause the bar to be unable to be vertically placed on the stamping table. Even if the bar is positioned by the clamping jaw during the stamping process, the bar can still be inclined during the pressing process. The specific reasons are as follows. The stamping bar is sent to the stamping table by the clamping jaw. The stamping device presses the bar. When the cutting inclined surface of the bar contacts the stamping table, the bar is pressed and inclined, which causes the stamping device to be unable to stamp the specified position of the steel bar. This results in that the heights of the nuts after stamping are inconsistent, and the yield of the nuts is reduced. SUMMARY

[0005] The application aims at solving the technical problems in the prior art by providing a stamping device for large fasteners.

[0006] The application can be realized by the following technical scheme. A stamping device for large fasteners comprises a stamping assembly. The power end of the stamping assembly is connected to a power member. A die is mounted on the power member. A stamping table is mounted on the stamping assembly. The die is located on the top of the stamping table. A horizontal plate is mounted on the side wall of the stamping assembly. A support is mounted on the horizontal plate. A liftable material cylinder is mounted on the support. A detection feeding assembly is mounted between the material cylinder and the stamping table. The detection feeding assembly comprises a rotating table and a transmission table. The rotating table is rotatably mounted on the side wall of the transmission table. An outer sleeve and an inner sleeve are mounted on the rotating table. A rotatable tooth sleeve is mounted between the outer sleeve and the inner sleeve. A clamping plate is slidably mounted in the tooth sleeve. The rotating table is driven by a motor.

[0009] As a further optimization or improvement of the present scheme, the input end of the transmission table is connected with a cam, the cam is located in the inner sleeve, and the cam abuts against the push sleeve; one end of the clamping plate is slidingly installed in the inner sleeve of the push sleeve.

[0010] As a further optimization or improvement of the present scheme, a through groove is formed in the tooth sleeve, an inclined sliding groove is formed in the through groove, a sliding block is installed on the clamping plate, the sliding block is slidingly located in the inclined sliding groove, and a spring is installed between the sliding block and the inner wall of the inclined sliding groove.

[0011] As a further optimization or improvement of the present scheme, a liftable tooth plate is installed between the visual detection assembly one and the visual detection assembly two, the bottom of the cavity between the outer sleeve and the inner sleeve is provided with an opening, and the tooth plate extends into the cavity between the outer sleeve and the inner sleeve and is meshed with the outer tooth ring of the tooth sleeve.

[0012] As a further optimization or improvement of the present scheme, an inner tooth ring is installed at the bottom of the rotary table, and a motor is installed on the stamping assembly; the gear of the motor is meshed with the inner tooth ring to drive the rotary table to rotate.

[0013] As a further optimization or improvement of the present scheme, a sliding sleeve is installed in the rotary table, and the sliding sleeve is sleeved with the tooth sleeve.

[0014] The present application has the following advantages:

[0016] If the visual detection assembly one detects that the bottom section of the bar is not flat, the clamping plate is rotated so that the other side of the bar faces downwards; as the rotary table rotates, the other side of the bar is detected by the visual detection assembly two; if the other side of the bar meets the requirements, the bar is sent to the stamping table through the rotary table and the clamping plate, and the stamping work is completed by driving the mold downwards through the power member; if the other side of the bar still does not meet the requirements, the transmission table is closed, the cam is stationary, the push sleeve and the clamping plate are reset, and the transmission table is separated from the clamping of the bar; in this way, the bar that cannot be vertically placed on the stamping table is screened out, the cutting inclined surface of the bar is prevented from directly contacting the stamping table under pressure, the bar is prevented from being inclined or bent under pressure, and the yield of the parts is improved.

[0045] It should be noted that the rod needs to be perpendicular to the horizontal plate 5 to ensure the accuracy of the measurement of the visual detection assembly 603, and to avoid errors caused by the inclination of the rod, thereby avoiding misjudgment. Since the material cylinder 8 is perpendicular to the horizontal plate 5, one end of the rod is in contact with the horizontal plate 5, and the other end of the rod is in the material cylinder 8, at this time, the material cylinder 8 supports the rod, so that the rod is perpendicular to the horizontal plate 5, even if the cross section of the rod is inclined, the rod and the horizontal plate 5 are still in a vertical state; after the clamping plate 605 clamps the rod, the material cylinder 8 moves upwards, so that the material cylinder 8 is separated from the rod, thereby avoiding the movement interference between the clamping plate 605 and the material cylinder 8.

[0046] Referring to Figure 5 The rotating table 601 is provided with a sliding sleeve 611, and the sliding sleeve 611 is sleeved with the tooth sleeve 609.
