Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a forming device for the production of chain blades. Background Technology

[0002] As the core component of a chainsaw, chain blades are typically produced by hot forging, where high-temperature blanks are stamped into a preliminary shape, followed by subsequent finishing processes. During the hot forging process, the die cavity is prone to residual oxide scale, metal shavings, and lubricant due to the high temperature and pressure. It is necessary to clean and reapply lubricating oil promptly after each forming process to ensure die cooling, reduce wear, and ensure the stability of the next forming cycle.

[0003] Currently, mold cavity cleaning and lubrication operations mainly rely on manual labor. Operators need to hold a cloth and reach into the mold to wipe and apply the lubricant, which is not only inefficient and labor-intensive, but also poses a risk of burns from high temperatures. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-3 .

[0025] A forming device for producing chain blades includes a base 1 and a mold 2 mounted on the base 1, wherein the mold 2 is fixed to the base 1. Figure 1 As shown.

[0026] The mold 2 is provided with a liftable mold core 201. Specifically, the mold 2 is provided with a lifting push rod 202. The lower end face of the mold core 201 is fixedly connected to the lifting end of the lifting push rod 202. The mold 2 is also provided with a limiting block or limiting platform to restrict the downward sliding of the mold core 201, so that the lifting push rod 202 is not subjected to the punching force when the mold core 201 is being stamped.

[0027] The mold 2 is provided with a cavity 203 that is adapted to the mold core 201, and the side wall of the mold core 201 is slidably and vertically disposed in the cavity 203.

[0028] A roller 101 for cleaning and lubricating the lifted mold core 201 is slidably provided on the base 1. The roller 101 is coated with oil so that it reciprocates in contact with the mold core 201 to achieve cleaning and lubrication of the mold core 201; specifically, as shown in... Figure 1 As shown, positioning plates 104 are symmetrically arranged on the front and rear sides of the mold 2, and rollers 102 are fixed at both ends of the roller 101. The rollers 102 at both ends slide along the guide grooves 103 on the positioning plates 104 after passing through the positioning plates 104, so as to realize the sliding of the roller 101 relative to the surface of the mold 2.

[0029] The base 1 is symmetrically provided with drive push rods 105 connected to the rollers 102 at both ends. The cylinder end of the drive push rod 105 is rotatably disposed on the right side of the mold 2, and the push rod end is sleeved on the roller 102 through a collar 5. The drive push rod 105 is inclined upward from right to left towards one end of the roller 102. Figure 1 and Figure 2 As shown.

[0030] The roller 102 is rotatably connected to the collar 5. When the drive push rod 105 drives the roller 101 to slide, the roller 101 can synchronously rotate relative to the collar 5. The guide groove 103 is provided through the positioning plate 104, such as... Figure 1 and Figure 3 As shown, the guide groove 103 includes a reset groove 11, a lifting groove 12, and a working groove 13 extending from left to right. The reset groove 11, the lifting groove 12, and the working groove 13 are connected end to end to form the guide groove 103. The working groove 13 and the reset groove 11 are grooves parallel to the horizontal plane of the base 1, and the working groove 13 is set higher than the reset groove 11. The lifting groove 12 is inclined upward from one side of the reset groove 11 to the other side of the working groove 13. The joint of each groove has an arc-shaped joint surface to make the roller 102 slide smoothly.

[0031] An oil tank 3 is provided on the base 1. The oil tank 3 is located at a position corresponding to the reset groove 11 and is located on one side of the mold 2. Figure 1As shown, it is located on the left side of the mold 2. When the roller 101 is in the reset groove 11, the surface of the roller 101 can contact the oil in the oil tank 3 to absorb and clean the roller.

[0032] The oil tank 3 has an inclined filter plate 301, which is located at a position corresponding to the lifting groove 12, and its inclination direction is consistent with the inclination direction of the lifting groove 12. When the roller 101 is in the lifting groove 12, the surface of the roller 101 can contact and squeeze the filter plate 301 to filter the excess oil in the roller 101 into the oil tank 3. The roller 101 is a flexible roller, which is made of high temperature resistant material. Specifically, the surface of the roller 101 can be made of oil-absorbing material such as high temperature resistant polyester or cotton yarn, and has a certain compression stroke.

[0033] The mold 2 has a slide 4 connected to the mold surface on the right side. When the molded workpiece is pushed out by the lifting push rod 202, the roller 101 is driven and rolls through the reset groove 11 to suck oil into the lifting groove 12 to squeeze out excess oil. Then it enters the working groove 13. After the roller 101 slides to the right, it pushes the workpiece in the mold core 201 into the slide 4 and collects it. At the same time, the oil on the surface of the roller 101 cleans and lubricates the mold core 201. Then the roller 101 is driven to reset by the push rod 105. When passing through the filter plate 301, some impurities adhering to the roller 101 are removed into the oil tank 3. The roller 101 is cleaned when it rolls in the reset groove 11.

[0034] The roller 102 is preferably a damping shaft with wear-resistant damping particles, such as alloy particles, on its surface, so that when the roller 102 slides in the guide groove 103, the roller 101 can also rotate relative to the sleeve 5.

[0035] The lifting push rod 202 and the driving push rod 105 can be electric push rods or pneumatic or hydraulic push rods, and there is no limitation here.

[0036] The method using the forming apparatus described above for the production of chain blades:

[0037] S1: Core lifting: After hot forging is completed, the lifting push rod 202 pushes the core 201 to rise outside the mold 2;

[0038] S2: Roller drive: Drive push rod 105 pulls roller 102 to move along guide groove 103. Roller 101 enters working groove 13 from reset groove 11 through lifting groove 12 and rises vertically to the surface of mold core 201.

[0039] S3: Cleaning and lubrication: While the roller 101 contacts the mold core 201, it pushes the mold core 201 and the stamped workpiece onto the slide table 4 and slides down. At the same time, it drives the push rod 105 to move back and forth, scraping off the residue from the flexible surface and coating it with oil.

[0040] S4: Reset and recovery: Drive push rod 105 is pushed out, roller 101 returns to reset groove 11 along guide groove 103, dripping oil flows back to oil tank 3 after being filtered by filter plate 301. At the same time, roller 101 scrapes off impurities after passing through filter plate 301, causing impurities to settle to the bottom of oil tank 3.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
