Description

Technical Field

[0001] This utility model relates to the field of cold heading machine technology, specifically a multi-station cold heading machine for textile steel rings. Background Technology

[0002] A cold heading machine is a mechanical device that utilizes the principle of metal plastic deformation to apply pressure to metal billets at room temperature through a cold heading process, thereby forming fasteners, irregularly shaped parts, or special components. It uses dies to extrude, upset, and reduce the diameter of metal bars such as carbon steel, stainless steel, and copper alloys, causing them to plastically deform and form the desired geometric shape. It can be used to produce high-strength parts such as engine bolts and chassis fasteners, manufacture precision connectors made of titanium alloys and high-temperature alloys, cold-headed micro screws, rivets, and other high-precision parts, and mass-produce standard parts.

[0003] In existing technologies, cold heading machines require regular lubrication of the die head when producing textile rings to reduce wear. To facilitate lubrication, we propose a multi-station cold heading machine for textile rings. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1-3A multi-station cold heading machine for textile steel collars includes a base 1. Multiple die slots 2 are fixedly connected to the upper end of the base 1. These die slots are arranged in a circular array, allowing for the simultaneous processing of multiple workpieces. A top frame 7 is positioned above the base 1, and multiple hydraulic rods 6 are fixedly connected to the lower end of the top frame 7. These hydraulic rods are servo-controlled, enabling precise pressure adjustment. Connecting seats 5 are fixedly connected to the extended ends of each hydraulic rod 6. Die heads 4 are mated to the lower ends of each connecting seat 5. The surfaces of the die heads 4 are chrome-plated to reduce friction and wear. The positions of the die heads 4 correspond vertically to the positions of the die slots 2, ensuring precise alignment during processing. A device frame 8 is fixedly connected between the base 1 and the top frame 7. A sliding groove is provided through the side wall of the device frame 8, and a movable plate 3 is installed inside the sliding groove. The dimensions of the movable plate 3 are precisely matched with the sliding groove to ensure smooth sliding. An oil delivery groove is provided through the movable plate 3. The oil delivery groove adopts a T-shaped cross-section design to increase the oil flow area. Multiple nozzles 15 are fixedly connected to the side wall of the movable plate 3. These nozzles 15 adopt an adjustable design, which can adjust the spray angle according to different processing requirements. An oil pipe 14 is fixedly connected to the lower end of the movable plate 3. The oil pipe 14 is made of high-pressure resistant rubber material, which has good flexibility and sealing performance. A moving device is fixedly connected to the inner wall of the sliding groove at the corresponding position. The connecting column 10 of the moving device is fixed to the inner wall of the sliding groove with bolts. The moving device includes a connecting column 10 fixedly connected to the inner wall of the chute. The connecting column 10 and the inner wall of the chute are interference-fitted to ensure a firm connection. An electric telescopic rod 9 is fixedly connected through the side wall of the connecting column 10. The electric telescopic rod 9 has a built-in high-precision displacement sensor, which can achieve μm-level control. The extended end of the electric telescopic rod 9 is fixedly connected to the side wall of the moving plate 3. The oil storage tank 12 is made of stainless steel to prevent oil contamination.

[0015] Specifically, an oil storage device is installed through the side wall of the device frame 8. The position of the oil storage device is designed to facilitate the operator's observation of the liquid level and the addition of oil. The oil storage device includes a groove through the side wall of the device frame 8, in which an oil tank 12 is slidably installed. The oil tank 12 is equipped with a transparent observation window for easy monitoring of the oil volume. A magnetic sheet 13 is fixedly connected to the side wall of the oil tank 12. The magnetic sheet 13 is made of neodymium iron boron and has extremely strong magnetism. Another magnetic sheet 13 is fixedly connected to the inner wall of the groove at the corresponding position. The magnetic fields of the two magnetic sheets 13 attract each other, providing reliable positioning. The two magnetic sheets 13 in opposite positions are magnetically attracted to each other. The magnetic attraction force is designed just right, ensuring both fixation and easy removal for maintenance. The upper end of the oil tank 12 is fixedly connected to the injection nozzle 11, which is equipped with a dust cover to effectively prevent impurities from entering.
