Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, specifically to a main slider adjustment structure for a cold heading machine. Background Technology

[0002] A cold heading machine is a device that cuts and cold-extrudes processed metal wire, causing the wire to be cold-headed into shape within a mold. It can be used to process various fasteners such as screws. During operation, the male mold on the main slide needs to move back and forth to cooperate with the female mold for the die-casting process. However, due to material properties, temperature changes, and other factors, there are tolerances when the male mold cooperates with the female mold, requiring adjustment. Existing main slide adjustment mechanisms are cumbersome, time-consuming, and labor-intensive, thus affecting work efficiency. Summary of the Invention

[0003] The purpose of this utility model is to provide a main slider adjustment structure for a cold heading machine. When the adjustment seat moves, it drives the male mold to slide back and forth in the sliding hole, thereby adjusting the position of the male mold. The operation is convenient and quick, and the work efficiency is improved.

[0004] To solve the above technical problems, this utility model adopts the following technical solution: a main slide adjustment structure for a cold heading machine, including an adjustment shell and a male mold. The adjustment shell has an adjustment cavity inside and a first screw hole at the top communicating with the adjustment cavity. An adjustment seat that can slide up and down is provided inside the adjustment cavity. It also includes an adjustment screw threadedly connected to the first screw hole. The top end of the adjustment seat is rotatably connected to the lower end of the screw. The front end of the adjustment seat has a slope that slopes downward from back to front. The front end of the adjustment shell has a mounting seat with a sliding hole. The male mold can slide back and forth in the slide block. The rear end of the male mold is connected to an inclined pad that can slide with the adjustment seat. The rear end face of the inclined pad slopes downward from front to back.

[0005] Using the above scheme, during adjustment, rotating the adjusting screw causes it to move axially relative to the first screw hole, thereby driving the adjusting seat to slide up and down. As the adjusting seat moves, the sliding cooperation between the slope and the inclined pad causes the male mold to slide back and forth in the sliding hole, thereby adjusting the position of the male mold so that it can cooperate with the female mold. The adjustment operation is convenient and quick, thereby improving work efficiency.

[0006] Furthermore, it also includes a locking structure for locking the male mold backward. The side wall of the mounting base is provided with a second screw hole. The locking structure includes a slanted groove provided on the side wall of the male mold with its opening facing forward and a locking screw threaded into the second screw hole. The inner end of the locking screw is inclined to the rear and abuts against the slanted groove.

[0007] Using the above method, after adjusting the position of the male mold, rotate the locking screw. The locking screw is displaced relative to the second screw hole, and the locking screw applies a backward force to the male mold. At this time, the front and rear sides of the male mold are simultaneously subjected to thrust, thus locking it.

[0008] Furthermore, it also includes a clamping assembly for axially locking the adjusting screw. The clamping assembly includes a pressure plate disposed above the adjusting housing and a pressure-bearing part sleeved on the upper end of the adjusting screw. The pressure plate is provided with an adjusting block that can slide up and down and a transmission screw. The adjusting block has a third screw hole and is threadedly connected to the adjusting screw. The side wall of the pressure-bearing part is provided with an annular protrusion. The lower side of the adjusting block abuts against the upper side of the annular protrusion. The top of the pressure plate is provided with a groove, and the adjusting block slides up and down in connection with the groove.

[0009] Using the above method, after adjusting the position of the male mold, rotate the transmission screw. The transmission screw drives the adjusting block to slide down along the groove and then abut against the annular protrusion, thereby pressing the adjusting screw down and locking it axially.

[0010] The beneficial effects of this utility model are as follows: During adjustment, rotating the adjusting screw causes it to move axially relative to the first screw hole, thereby driving the adjusting seat to slide up and down. When the adjusting seat moves, the sliding cooperation between the slope and the inclined pad causes the male mold to slide back and forth in the sliding hole, thereby adjusting the position of the male mold so that it can cooperate with the female mold. The adjustment operation is convenient and quick, thereby improving work efficiency. Attached Figure Description
