Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing and relates to a water cooler used for a brake of a large hot forging press. Background Art

[0002] The brake is the control component for the slide of a large hot forging press, primarily ensuring the slide's accurate position. The brake primarily relies on the friction of the friction disc to stop the slide's movement. Frequent braking, at 10-15 times per minute, causes severe brake heating, necessitating the use of a water cooler to cool the brake's active disc and prevent overheating, which could burn out the brake pads. Currently, there are two structures of water coolers for press brakes. One is a solid cooler, which has only one annular cooling pipeline with a diameter of 20. The water volume ratio of the cooler is very small, and the cooling effect is poor, resulting in the operating temperature of the brake friction plate being greater than 100°C and a short service life. The other cooler is a hollow cooler, which is welded along the root circle of the cooling gear disc. The welding process groove width is 25mm, which reduces the tooth stress area by 1 / 3 when the brake is applied. The braking torque it withstands is limited, and the tooth wears faster. At the same time, the hollow structure of the cooler lacks a stress support surface inside, and cannot withstand the frequent impact of the brake's clamping braking force for a long time, causing the stress surface of the cooler to deform and sink, resulting in a short service life. In addition, once the end face of the cooler with this structure is worn, it cannot be repaired. Utility Model Content

[0003] In response to the problems existing in the prior art, the utility model provides a water cooler for the brake of a large hot forging press, which has a good cooling effect and can control the operating temperature of the brake below 70°C. At the same time, the cooler can withstand the frequent impact of the pressing braking force of the press brake, and can withstand a large braking torque when the brake is applied, and has a service life of more than 5 years.

[0004] The utility model is realized through the following technical solutions:

[0005] A water cooler for a large hot die forging press brake, comprising:

[0006] Water-cooled gear plate, welding plate and tensioning screw;

[0007] The welding disk is welded to the water-cooled gear disk; one end of the tightening screw is fixedly mounted on the water-cooled gear disk; the other end of the tightening screw is riveted to the welding disk; a supporting boss is circumferentially arranged on the water-cooled gear disk, and the tightening screw is mounted on the supporting boss.

[0008] Preferably, a threaded hole is provided on the supporting boss, and the tightening screw is fixedly installed in the threaded hole.

[0009] Preferably, an annular groove is provided on the water-cooling gear disc, and the supporting boss is arranged in the annular groove.

[0010] Preferably, water troughs are provided on both sides of the supporting boss.

[0011] Preferably, the water cooler is provided with a water inlet at the lower end and a water outlet at the upper end.

[0012] Preferably, the water inlet and the water outlet are both communicated with the water tank.

[0013] Preferably, the supporting boss is a fan-shaped structure.

[0014] Preferably, the water cooler is a hollow annular structure.

[0015] Preferably, the water cooler is an external tooth structure, and the external teeth of the water cooler are fitted with the internal teeth of the press brake housing.

[0016] Preferably, the welding position of the water cooler is set on the end face, and the welding depth is greater than 10 mm.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] The utility model designs a water cooler for a brake of a large hot forging press, comprising a water-cooled gear disc, a welding disc and a tensioning screw; the welding disc is welded to the water-cooled gear disc; one end of the tensioning screw is fixedly mounted on the water-cooled gear disc; the other end of the tensioning screw is riveted to the welding disc; a supporting boss is circumferentially arranged on the water-cooled gear disc, and the tensioning screw is mounted on the supporting boss; when the brake is applied, a huge spring force pushes and compresses the brake friction disc, and the brake friction disc hits the end face of the compression cooler, and the fan-shaped supporting boss designed inside the cooler plays a role in bearing the spring compression force; at the same time, the tensioning screw designed in the cooler also increases the bearing capacity of the braking torque. By providing a support boss for supporting the brake welding disc of the cooler, the cooler is ensured to withstand the frequent impacts of the brake's clamping force. This effectively solves the problem in the prior art that the hollow cooler lacks internal force support and cannot withstand the frequent impacts of the brake's clamping force for a long time, resulting in deformation and depression of the brake cooler's force-bearing surface. The utility model can control the summer operating temperature of the hot die forging press brake to below 70°C, and can achieve a service life of the brake friction pad of more than 6 months. It can also achieve the frequent impact of the press brake cooler under the condition of large braking force without deformation or depression. The utility model can achieve the hot die forging press brake cooler to withstand greater braking torque, and the cooler's service life can reach more than 5 years.

[0019] Furthermore, by designing the cooling water channel of the brake cooler as an annular groove, the cooling water volume is increased by more than 5 times; the annular cooling water groove also increases the cooling contact area of ​​the water cooler by more than 5 times; the cooling effect is greatly improved, the summer operating temperature of the brake friction disc is reduced to below 70°C, and the winter operating temperature is reduced to below 50°C, and the service life of the brake friction pad is greatly improved, which effectively solves the problem in the prior art that the solid cooler has only one cooling pipe with a diameter of 20, the cooling water volume is too small, the brake cooling effect is poor, the friction pad operating temperature is greater than 100°C, and the service life is short.

[0020] Furthermore, the present invention's water cooler welds are located on the end face, with a weld depth greater than 10mm. This eliminates the need for welding grooves on the cooler's tooth profile, maximizing the tooth's stress-bearing area and the maximum braking torque it withstands. This effectively addresses the prior art issue of hollow coolers where welding is performed on the tooth root circle, creating a 25mm-wide weld groove. This reduces the cooler's tooth stress-bearing area by one-third and leads to faster tooth wear.

[0021] Furthermore, the water grooves left on both sides of the supporting boss of the present invention ensure the circulation of cooling water.

[0022] Furthermore, the press brake cooler of the present invention features an external tooth structure that fits snugly within the internal teeth of the press brake housing. The brake housing and the machine bed are secured in a stationary state by bolts and locating keys. When the press brakes, a powerful brake spring rapidly pushes the stationary water cooler along its external tooth surface, pressing against the rotating brake friction disc. Friction rapidly brings the disc to a standstill, achieving the desired braking effect. Frequent, forceful friction braking causes the brake to heat up, and the water cooler dissipates much of the heat, lowering its operating temperature.

[0023] Furthermore, the cooler of the present invention is designed with a cooling water inlet at the bottom and a cooling water outlet at the top. Low-temperature cooling water enters the cooler from the bottom, filling the cooler's cooling chamber, and flows out of the top outlet based on the pressure of the tap water line. Because the front and rear ends of the cooler also take into account the braking function of the brake, the front and rear ends of the cooler will generate severe heat during the operation of the press. The cooling water will remove a large amount of heat when passing through the cooling chamber inside the cooler, reducing the temperature of the brake. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The present invention will be further described in detail below with reference to specific embodiments, which are intended to explain rather than limit the present invention.

[0032] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0033] The utility model designs a new type of water cooler for a large hot die forging press brake, which has a good cooling effect and can control the working temperature of the brake below 70°C. At the same time, the cooler can withstand the frequent impact of the press brake's pressing braking force and can withstand a large braking torque when the brake is applied, with a service life of more than 5 years.

[0034] like Figure 1 and Figure 4 As shown, a water cooler for a large hot forging press brake comprises a water-cooled gear disc 1, a welding disc 2 and a tensioning screw 3;

[0035] like Figure 2As shown, the welding disk 2 is welded to the water-cooling gear disk 1; when the welding disk 2 is welded to the water-cooling gear disk 1, the edges where the two are in contact are fully welded for complete sealing welding; the size of the welding disk 2 matches the size of the welding position of the water-cooling gear disk 1; the water cooler is a hollow annular structure; the water-cooling gear disk 1 is a hollow annular structure with teeth on the outer edge, and the welding disk 2 is a hollow annular structure with through holes on the surface;

[0036] like Figure 3 As shown, one end of the tensioning screw 3 is fixedly mounted on the water-cooled toothed disc 1; the other end of the tensioning screw 3 is riveted to the welding disc 2; one end of the tensioning screw 3 is provided with a thread, and one end of the tensioning screw 3 is fastened to the threaded hole of the water-cooled toothed disc 1 by the thread. The welding disc 2 and the water-cooled toothed disc 1 are welded together, and the tensioning screw 3 is matched with the through hole of the welding disc 2. Finally, welding is also required. After all the welding parts are completed, the tooth shape is processed. The tensioning screw 3 is a cylinder with a certain height made of steel.

[0037] At the same time, the preferred embodiment, by designing 12 M30 tensioning screws 3, plays the role of riveting the welding plate 2, ensuring that the welding plate 2 will not bulge and deform; the junction of the tensioning screw 3 and the welding plate 2 needs to be welded and riveted at the countersunk position before processing.

[0038] like Figure 5 and Figure 6 As shown, the water-cooled sprocket 1 is circumferentially provided with a support boss 6, and the tensioning screw 3 is installed on the support boss 6. The support boss 6 is provided with a threaded hole, and the tensioning screw 3 is fixedly installed in the threaded hole. The water-cooled sprocket 1 is provided with an annular groove, and the support boss 6 is arranged in the annular groove. This patent designs a number of fan-shaped support bosses 6 in the annular hollow cooling groove of the brake cooler, which are used to support the brake welding disc 2 of the cooler, thereby ensuring that the cooler can withstand the frequent impact of the brake clamping force; 50*35 water grooves are left on both sides of the support boss 6 to ensure the circulation of cooling water. It effectively solves the problem in the prior art that the hollow cooler lacks force support inside and cannot withstand the frequent impact of the brake's clamping force for a long time, resulting in deformation and depression of the force surface of the brake cooler.

[0039] In a preferred embodiment, the number of support bosses 6 evenly spaced apart is 4-6, and each support boss 6 is provided with 3 threaded holes to facilitate the installation of the tensioning screw 3;

[0040] In a preferred embodiment, an annular groove is provided on the water-cooled gear disc 1, and the supporting boss 6 is arranged in the annular groove. The cooling water path of the brake cooler designed in this patent is The annular groove increases the cooling water volume by more than five times; the annular cooling water groove also increases the cooling contact area of ​​the water cooler by more than five times, greatly improving the cooling effect. The operating temperature of the brake friction disc is reduced to below 70°C in summer and below 50°C in winter, greatly extending the life of the brake friction pad. This effectively solves the problem of the existing solid cooler having only one cooling pipe with a diameter of 20, which results in insufficient cooling water volume, poor brake cooling effect, friction pad operating temperature exceeding 100°C, and short life.

[0041] The water cooler is provided with a water inlet 4 at the lower end and a water outlet 5 at the upper end, and both the water inlet 4 and the water outlet 5 are communicated with the water trough; the water trough is arranged in the annular groove, and the supporting boss 6 is a fan-shaped structure, and the fan-shaped curvature is consistent with the circumferential angle of the water-cooled gear disc 1; the water cooler is an external tooth structure, and the external teeth of the water cooler are fitted together with the internal teeth of the press brake housing.

[0042] The water cooler's welding position is set on the end surface, and the welding depth is greater than 10mm. This eliminates the need for a welding process groove on the cooler's tooth profile, maximizing the tooth stress area and the maximum braking torque. This effectively solves the problem of the existing hollow cooler welding position being left at the root circle, with a 25-degree wide welding groove, which reduces the cooler's tooth stress area by 1 / 3 and causes rapid tooth wear.

[0043] The working process is as follows:

[0044] The press brake cooler of this utility model features an external tooth structure that fits snugly within the internal teeth of the press brake housing. The brake housing and the machine bed are secured in a stationary state by bolts and retaining keys. When the press brakes, a powerful brake spring rapidly pushes the stationary water cooler along its external tooth surface, pressing against the rotating brake friction disc. Friction rapidly brings the disc to a standstill, achieving the desired braking effect. Frequent, forceful friction braking causes the brake to heat up, and the water cooler dissipates much of the heat, lowering its operating temperature.

[0045] 2. If Figure 2 The cooler is designed with a cooling water inlet 4 at the bottom and a cooling water outlet 5 at the top. Low-temperature cooling water enters the cooler from the bottom, filling the cooler's cooling chamber, and flows out from the top outlet 5 based on the pressure of the tap water pipeline. Because the front and rear ends of the cooler also take into account the braking function of the brake, the front and rear ends of the cooler will heat up seriously during the operation of the press. The cooling water will carry away a large amount of heat when passing through the cooling chamber inside the cooler, reducing the temperature of the brake.

[0046] 3. When the brake is applied, the enormous spring force pushes and compresses the brake friction disc, which in turn impacts the end face of the cooler. The fan-shaped support boss 6 designed inside the cooler absorbs the spring's compressive force. Furthermore, the cooler's tensioning screw 3 also increases its ability to withstand braking torque.

[0047] The utility model can control the working temperature of the hot die forging press brake to be below 70° C. in summer, and can extend the service life of the brake friction plate to more than 6 months.

[0048] The utility model can realize that the cooler of the press brake can withstand frequent collisions under the condition of large braking force without deformation or depression.

[0049] The utility model can realize that the brake cooler of the hot die forging press can bear a larger braking torque, and the service life of the cooler is more than 5 years.
