Description

Technical Field

[0001] The present invention relates to the technical field of chip cake machines, and particularly to a high-temperature resistant mold cylinder for a chip cake machine that can be reused. Background Art

[0002] A chip cake machine is used to press various metal chips such as turning chips, shavings, drill chips, and milling chips generated after processing into cake blocks with higher density through high pressure. These cake blocks can be directly put into a metal smelting furnace, which plays a certain role in the recycling of recycled metals and also meets the requirements of the country's new environmental protection policy. The operation steps of the chip cake machine mainly include steps such as hopper feeding, feeding, extrusion, and demolding. Among them, the extrusion and demolding links are completed by a mold cylinder and a pressure rod.

[0003] With the development of the aluminum chip melting process, a process of directly extruding aluminum chips into rods by heating them to 350°C - 500°C (without melting) in an oxygen-free environment has emerged. However, in a long-term high-temperature environment, the material of the mold cylinder undergoes low-temperature tempering, resulting in a reduction in the surface hardness of the mold, increased wear, and a sharp shortening of the service life. At the same time, during the pressing process, the mold cylinder bears a huge pressure in the radial direction, is prone to fatigue cracking, and even partially breaks off, causing the mold cylinder to be scrapped;

[0004] Therefore, a high-temperature resistant mold cylinder for a chip cake machine that can be reused is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-temperature resistant mold cylinder for a chip cake machine that can be reused, which solves the problem of high scrapping frequency of the mold cylinder of the chip cake machine in the prior art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A high-temperature resistant mold cylinder for a chip cake machine that can be reused, comprising:

[0008] An outer fixing sleeve, a spiral water groove is provided on the inner side of the outer fixing sleeve, two sets of hole seals are provided on the inner side of the outer fixing sleeve, and the two sets of hole seals are respectively located at the upper and lower ends of the spiral water groove. An outlet channel communicating with the bottom end of the spiral water groove is provided in the outer fixing sleeve, and an inlet channel communicating with the top end of the spiral water groove is provided in the outer fixing sleeve;

[0009] A lining sleeve, a plurality of avoiding grooves are provided on the outer wall of the lining sleeve in an annular array, a plurality of vertical grooves are provided on the inner wall of the lining sleeve corresponding to the avoiding grooves, an annular groove intersecting with the vertical grooves is provided on the inner wall of the lining sleeve coaxially. The lining sleeve is inserted into the outer fixing sleeve from top to bottom and abuts against the bottom inner wall of the outer fixing sleeve to limit the lining sleeve from sliding out from the bottom end of the outer fixing sleeve;

[0010] A flange, the flange is installed at the top of the outer fixing sleeve, and the flange abuts against the top end of the inner lining sleeve to form a die barrel. A water outlet joint, a temperature sensor and a water inlet joint are installed on the side wall of the flange. An inlet hole and an outlet hole are opened inside the flange. The water inlet joint is communicated with the water inlet channel through the inlet hole, the water outlet joint is communicated with the water outlet channel through the outlet hole, and the detection end of the temperature sensor abuts against the outer wall of the inner lining sleeve.

[0011] Preferably, a water inlet pipe is connected to the outside of the water inlet joint, and a water outlet pipe is connected to the outside of the water outlet joint, and the water inlet pipe and the water outlet pipe are respectively communicated with the water inlet end and the water outlet end of the chiller.

[0012] Preferably, two sealing ring grooves are opened on the inner side of the outer fixing sleeve and are respectively used for the limit installation of two hole-use sealing rings.

[0013] Preferably, an end face sealing ring is arranged between the outer fixing sleeve and the flange for the sealed connection of the inlet hole and the inlet channel and for the sealed connection of the outlet hole and the outlet channel.

[0014] Preferably, a protruding shoulder is arranged on the outer wall of the inner lining sleeve so that the outer diameter of the annular shoulder is larger than the outer diameter of the inner lining sleeve. An inwardly protruding annular boss is arranged on the inner wall of the outer fixing sleeve. The top end of the shoulder abuts against the lower end face of the flange, and the bottom end of the shoulder abuts against the upper end face of the annular boss.

[0015] Preferably, the spiral water groove is located at a position directly opposite to the shoulder, and the sealing ring groove above the spiral water groove is arranged at a position directly opposite to the shoulder, and the sealing ring groove below the spiral water groove is arranged at a position directly opposite to the annular boss.

[0016] Preferably, the inner wall of the bottom of the inner lining sleeve is a conical surface, and the inner diameter of the annular conical surface is larger than the inner diameter of the top of the inner lining sleeve.

[0017] Preferably, a sealing strip fitting the inner wall of the outer fixing sleeve is arranged inside the avoidance groove, and the upper and lower ends of the avoidance groove respectively penetrate through the upper and lower ends of the inner lining sleeve.

[0018] The present invention has at least the following beneficial effects:

[0019] 1. The inner lining sleeve is fixed inside the outer fixing sleeve under the action of the flange and the outer fixing sleeve to prevent the inner lining sleeve from axially moving during the pressing of the aluminum rod, which can effectively improve the stability of the entire die barrel; and when the inner lining sleeve is worn out and cannot be used, the flange can be removed, and then the inner lining sleeve can be taken out upward from the outer fixing sleeve, making the replacement of the inner lining sleeve simple and convenient. Compared with replacing the entire die barrel, the replacement cost is effectively reduced.

[0020] 2. By setting the vertical groove and the annular groove, the inner liner guides the crack to radiate radially, and the avoidance groove corresponds to the vertical groove one by one, which can effectively guide the crack to radiate from the vertical groove into the avoidance groove, improving the accuracy of crack guidance; a sealing strip is provided in the avoidance groove, so that the cooling water will not leak along the avoidance groove; when the inner liner is worn out and cannot be used, the inner liner is directly pressed out of the outer fixing sleeve, which requires a relatively large pressure. At this time, wire cutting can be carried out through the avoidance groove, cutting from the inner wall of the inner liner to the avoidance groove, which will not damage the inner hole of the outer fixing sleeve, and the inner liner can be easily taken out after being cut into multiple pieces, effectively improving the convenience of replacement.

[0021] 3. Through the water-cooling structure of the spiral water groove, the temperature sensor accurately feedbacks the temperature on the outer wall of the inner liner, so that the outer wall of the inner liner can be cooled cyclically in time, preventing the inner liner from undergoing low-temperature tempering, reducing the occurrence of the surface hardness reduction and increased wear of the inner liner, and effectively improving the overall service life of the die barrel.
