Description

Technical Field

[0001] This utility model belongs to the field of bolt processing technology, and in particular relates to a batch heat treatment equipment for bolts. Background Technology

[0002] A bolt is a cylindrical threaded fastener used in mechanical parts to be fitted with a nut. It consists of a head and a threaded shank, and requires a nut to fasten two parts with through holes. This type of connection is called a bolted connection. Since the two parts can be separated by unscrewing the nut, a bolted connection is a detachable connection. Bolts require a heat treatment process during production.

[0003] Existing equipment is not convenient for freely controlling the number of bolts to be heat-treated. When encountering bolts of different sizes, the equipment needs to be changed before subsequent operations can be carried out. Furthermore, it is not convenient to remove oxides from the surface of the bolts after heat treatment. Therefore, we propose a batch heat treatment equipment for bolts. Utility Model Content

[0004] The purpose of this utility model is to provide a batch heat treatment equipment for bolts. By using a placement plate, it solves the problems of existing equipment, such as the inconvenience of freely controlling the number of bolts to be heat treated, the need to change equipment before subsequent operations can be carried out when encountering bolts of different sizes, and the inconvenience of removing oxides from the surface of the bolts after heat treatment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a batch heat treatment equipment for bolts, comprising a connecting plate, a heating chamber fixedly connected to the top of the connecting plate, a dust removal chamber fixedly connected to the top of the connecting plate, an outer wall of the heating chamber fixedly connected to the outer wall of the dust removal chamber, a plurality of slide rails fixedly connected to the inner wall of the heating chamber, a transmission mechanism provided on the outer wall of the dust removal chamber, the transmission mechanism including a motor frame, the outer wall of the motor frame fixedly connected to the outer wall of the dust removal chamber, a motor fixedly connected to the outer wall of the motor frame, and a cleaning mechanism provided inside the dust removal chamber, the cleaning mechanism including a plurality of slide grooves, a filter plate slidably connected to the inner wall of the upper slide groove, and a collection plate slidably connected to the inner wall of the lower slide groove.

[0007] Using the above technical solution, the cleaned bolts will fall onto the filter plate, and the removed oxides will flow through the filter plate and into the collection plate with the water flow.

[0008] Furthermore, a placement plate is slidably connected to the inner wall of the slide rail, a heating wire is fixedly connected to the inner wall of the heating chamber, a number of hinges are fixedly connected to the outer wall of the heating chamber, and a number of hinges are fixedly connected to the outer wall of the dust removal chamber.

[0009] The above technical solution allows for the insertion of bolts with the larger end facing upwards into the placement holes on the placement plate, thus suspending the bolts in the air and preventing uneven heating.

[0010] Furthermore, a sealing door is fixedly connected to the inner wall of the hinge on the left side, and the outer wall of the sealing door is slidably connected to the inner wall of the heating chamber. A second sealing door is fixedly connected to the outer wall of the hinge on the right side, and the outer wall of the second sealing door is slidably connected to the interior of the dust removal chamber.

[0011] Through the above technical solutions, the sealed door can ensure the temperature inside the heating chamber, prevent heat leakage, and reduce the energy consumption required for bolt heat treatment.

[0012] Furthermore, a number of limiting shafts are fixedly connected to the outer wall of the slide rail near the hinge, and a number of anti-slip pads are fixedly connected to the inner wall of the placement plate.

[0013] Through the above technical solution, the anti-slip pad can prevent the oxide on the surface of the bolt from falling off during the heating process, which would cause the bolt volume to decrease and thus fall off.

[0014] Furthermore, the bottom output end of the motor is fixedly connected to a drive shaft via a coupling, and several rotating shafts are rotatably connected to the inner wall of the dust removal chamber near the drive shaft, with gears fixedly connected to the outer wall of the rotating shaft.

[0015] Through the above technical solution, the rotation of the motor drives the rotation of the transmission shaft, and the rotation of the transmission shaft drives the rotation of the gear.

[0016] Furthermore, a roller brush is fixedly connected to the outer wall of the end of the rotating shaft away from the motor, and a limit seat is rotatably connected to the outer wall of the roller brush. The outer wall of the limit seat is fixedly connected to the outer wall of the dust removal chamber, and a partition plate is fixedly connected to the inside of the dust removal chamber.

[0017] Through the above technical solution, the separator plate can divide the bolts into two strands, preventing excessive bolts at one time from causing excessive load on the roller brush and damaging the roller brush, while increasing the number of bolts per cleaning cycle.

[0018] Furthermore, a water storage tank is fixedly connected to the top of the dust removal chamber, and a water inlet is provided on the top of the water storage tank. A water supply pipe is fixedly connected to the outer wall of the water storage tank, and the outer wall of the water supply pipe is fixedly connected to the inner wall of the dust removal chamber.

[0019] Using the above technical solution, water is injected into the water storage tank, and the water flows into the water pump through the water pipe. The water pump can automatically control the water flow.

[0020] Furthermore, a water pump is fixedly connected to the outer wall of the water supply pipe, and several nozzles are fixedly connected to the outer wall of the water pump. A feeding port is provided at the top central axis of the dust removal chamber.

[0021] Through the above technical solution, the nozzle can spray water evenly inside the device to clean the bolts evenly, while the water flow will carry away the surface of the bolts and the removed oxides.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model features a placement plate. When the equipment is needed, the bolts are placed on the placement plate. The anti-slip pad prevents the bolts from falling off. The user can freely place the placement plate on different slide rails according to the actual situation. The heating wire is activated to heat-treat the bolts. After the bolts cool down, oxides will adhere to the surface. Water is then injected into the water tank to achieve the heat treatment of the bolts. The number of placement plates can be increased or decreased according to the actual situation of the bolts, and the number of bolts that can be heat-treated can be freely adjusted. The position of the placement plate can also be freely controlled to suit bolts of different sizes and to prevent the bolts from falling off.

[0024] 2. This utility model incorporates gears. During operation, the rotation of these gears drives multiple gears to rotate, causing multiple roller brushes to rotate. A water pump delivers water from the storage tank to multiple nozzles, achieving uniform spraying. Cooled bolts are fed into the dust removal chamber through the feeding port. As the bolts fall, they are separated into two groups by a partition plate. The rotating roller brushes remove oxides from the bolt surface, achieving cleaning of the oxides on the surface of the heat-treated bolts. Simultaneously, the bolts are uniformly cleaned and cooled. The processed impurities can be collected and treated to prevent contamination of the working environment, thus maintaining a clean working environment.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
