Description

Technical Field

[0001] This utility model belongs to the field of cutting tool cooling technology, and in particular relates to a cutting tool cooling structure for tapping machines. Background Technology

[0002] When tapping metal components with a tapping machine, the intense friction between the tool tip and the metal component causes a rapid increase in temperature. If the temperature is too high, the tool tip will experience an annealing effect, which will reduce its hardness and strength, leading to softening of the cutting edge, accelerated wear, and even chipping or breakage. High temperature may cause local thermal expansion of the workpiece, affecting the thread machining accuracy. Using coolant to drip directly onto the tool tip may result in the coolant not evenly covering the contact area between the tool and the workpiece, especially on the surface of the tool rotating at high speed. Local areas may still anneal or stick due to high temperature, and the intermittent flow of the droplets may cause the tool to experience a sudden temperature rise when the coolant is not covering it, exacerbating thermal stress fluctuations.

[0003] To address these issues, we provide a cutting head cooling structure for tapping machines. Utility Model Content

A set of water pipes is connected to the lower end of an annular water tank in the spray assembly. Water mist nozzles are connected to the lower ends of the water pipes, so that the water mist nozzles surround the cutting head in a ring, spraying coolant in a mist form onto the cutting head. This ensures that the cutting head receives the mist coolant evenly from all directions, preventing localized cooling. A blower in the blower assembly is connected to the water mist nozzles, which sprays the coolant from the nozzles to form a water mist. Simultaneously, the sprayed gas accelerates airflow over the cutting head surface, speeding up cooling.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Please see Figures 1 to 3 This utility model relates to a cooling structure for a tapping machine's cutting head, comprising a blower component 1 and a spray component 2. The blower component 1 includes a blower 101 and an airflow ring pipe 102. The spray component 2 includes an annular water tank 201 and a set of water mist nozzles 202. A set of water pipes 201a are arrayed and connected to the lower end of the annular water tank 201 in the spray component 2. The water mist nozzles 202 are connected to the lower end of the water pipes 201a, so that the set of water mist nozzles 202 surrounds the cutting head in an annular shape, spraying the coolant onto the cutting head in a mist form, so that the cutting head receives the mist coolant evenly from all directions, avoiding localized cooling of the cutting head. The blower 101 in the blower component 1 is connected to the water mist nozzles 202. The blower 101 sprays the coolant in the water mist nozzles 202 to form a water mist, and at the same time, the sprayed gas accelerates the airflow on the surface of the cutting head, accelerating the cooling of the cutting head.

[0028] Specifically, the air outlet of the blower 101 is connected to the side wall of the airflow ring pipe 102 through a pipe. A set of air outlet pipes 102a are connected in a circumferential array on the lower end of the airflow ring pipe 102. A set of water pipes 201a are connected in a circumferential array on the lower end of the annular water storage tank 201. A set of water mist nozzles 202 are connected to the end of each water pipe 201a away from the annular water storage tank 201. The air outlet pipes 102a are connected to the water mist nozzles 202.

[0029] Furthermore, the water mist nozzle 202 has an annular shell structure. A set of water mist holes 202a are circumferentially arrayed on the inner wall of the annular water mist nozzle 202. The end of the air outlet pipe 102a away from the airflow ring pipe 102 is connected to the annular opening side of the water mist nozzle 202. The coolant is inside the annular shell of the water mist nozzle 202. The high-speed airflow in the air outlet pipe 102a flows out from the annular opening of the water mist nozzle 202, while carrying the coolant in the water mist nozzle 202 out from the water mist holes 202a and forming a mist, so that the mist of coolant is evenly sprayed onto the cutter head.

[0030] Furthermore, a water inlet shell 202b is fixed on one side of the water mist nozzle 202. The upper end of the water inlet shell 202b is connected to the lower end of the water pipe 201a. The shell surface of the water mist nozzle 202 extends away from the axis of the annular water storage tank 201, and the end of the water mist nozzle 202 away from the water inlet shell 202b is tilted downward.

[0031] Furthermore, a water mist converging tube 202c is fixedly installed at the end of the water mist nozzle 202 away from the air outlet pipe 102a. The water mist converging tube 202c gathers the sprayed mist coolant to prevent the mist coolant from being too dispersed and thus failing to be accurately sprayed onto the cutter head surface.

[0032] The operation process in this embodiment is as follows:

[0033] The coolant in the annular water tank 201 flows through each water pipe 201a to each water mist nozzle 202. The blower 101 blows air into the airflow ring pipe 102. The airflow is split in the airflow ring pipe 102 and enters each air outlet pipe 102a. The high-speed airflow in the air outlet pipe 102a flows out from the annular opening of the water mist nozzle 202, and at the same time carries the coolant in the water mist nozzle 202 out from the water mist hole 202a and forms a mist, so that the mist coolant is evenly sprayed onto the cutter head.

[0034] Example 2

[0035] Please see Figures 1 to 5Based on Embodiment 1, the spray component 2 further includes an outer sleeve 203, and the cooling component 201c includes a set of annular plates 201c-1 and a set of cooling rods 201c-2. Each water pipe 201a is fixed by a set of water pipe sleeves 203a on the outside of the outer sleeve 203. The cooling rods 201c-2 cool the coolant in the annular water tank 201. At the same time, each annular plate 201c-1 is vertically sleeved in the annular water tank 201, so that the coolant stays between each annular plate 201c-1 for a longer time, so that the coolant is fully cooled.

[0036] Specifically, a set of water pipe sleeves 203a are fixedly arranged in a circumferential array on the outer sidewall of the outer sleeve 203, and each water pipe 201a is respectively sleeved in each water pipe sleeve 203a.

[0037] Furthermore, the upper end of the opening of the annular water storage tank 201 is covered with a tank cover 201b, and the upper end of the tank cover 201b is connected to a water inlet pipe 201b-1. A cooling component 201c is installed inside the annular water storage tank 201.

[0038] Furthermore, a sleeve 201c-3 is fixedly provided at the lower end of the annular plate 201c-1. A set of annular plates 201c-1 are vertically sleeved on the inner wall of the annular water storage tank 201. A set of cooling rod sleeve holes 201c-4 are opened through the plate surface of the annular plate 201c-1. The cooling rod 201c-2 passes through the tank cover 201b and is sleeved in the cooling rod sleeve holes 201c-4 of each annular plate 201c-1. A set of water permeable holes 201c-5 are opened through the plate surface of the annular plate 201c-1. The coolant enters the annular water storage tank 201 through the water inlet pipe 201b-1. The coolant on the annular plate 201c-1 flows downward through the water permeable holes 201c-5, so that the coolant stays above the annular plate 201c-1 for a longer time. At the same time, the cooling rod 201c-2 cools the coolant remaining on the annular plate 201c-1.

[0039] Furthermore, a temperature-conducting ring sleeve 201c-6 is fixedly sleeved on the outside of the sleeve sleeve 201c-3, and a set of temperature-conducting fins 201c-7 are axially arrayed and fixed on the outer side wall of the temperature-conducting ring sleeve 201c-6 to fully cool the coolant in the annular water storage tank 201.

[0040] The operation process in this embodiment is as follows:

[0041] The coolant flows downwards through the various water permeable holes 201c-5 on the annular plate 201c-1, allowing the coolant to remain above the annular plate 201c-1 for a longer period of time. At the same time, the cooling rod 201c-2 cools the coolant remaining on the annular plate 201c-1. After being cooled, the coolant flows through the water pipe 201a to the water mist nozzle 202, and is formed into a mist by the blower component 1 and sprayed onto the cutter head, causing the cutter head to cool down rapidly.
