Description

Technical Field

[0001] The utility model relates to the field of screw presses, in particular to a screw press. Background Art

[0002] Screw press is a general term for a pressurizing machine that generates pressure by rotating one or more sets of outer bolts and inner bolts within a frame. Screw press has no mechanical transmission and is directly driven by an electric motor. It has high transmission efficiency and low failure rate, and can meet various process requirements for forging strikes. It is superior to traditional presses in terms of energy saving and precise control of striking force, so it is widely used in major factories.

[0003] According to the published patent 201922107442.7, a fixed die frame for a screw press includes a body and a workbench. The workbench is connected to the inner wall of the body, and a transverse T-slot and a longitudinal T-slot are respectively cut on the top wall of the workbench. Push plates are connected to the inner walls of the transverse T-slot and the longitudinal T-slot. A hydraulic cylinder is rotatably connected to the top wall of the workbench. The output end of the hydraulic cylinder is rotatably connected to a first connecting rod. The end of the first connecting rod away from the hydraulic cylinder is connected to a crank-connecting rod mechanism. The crank-connecting rod mechanism is against the push plate. The transverse T-slot and the longitudinal T-slot are both connected to a lock. Tightening mechanism, and the locking mechanism is offset against the crank-connecting rod mechanism; the utility model has a simple structure and is easy to operate, and can effectively ensure that the axis center lines of the fixed mold frame and the body of the wire drop press are on the same axis, thereby effectively reducing the error during workpiece processing and improving the processing quality of the workpiece. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved: although the push plates in four directions are moved simultaneously, the fixed mold frame can be pushed and positioned at a position coaxial with the body, and then a locking mechanism is provided , and then the fixed die frame is stably fixed on the top wall of the workbench, so as to effectively avoid the situation that the fixed die frame and the axis of the machine body are not on the same axis, which leads to a large error in the processing of the workpiece, affecting the quality of the workpiece. It solves the problem that in the prior art, when the fixed die frame is fixed on the working platform of the screw press, it is manually positioned and fixed, so it is difficult to ensure that the axis of the fixed die frame and the screw press are on the same axis, which leads to a large error in the processing of the workpiece, affecting the processing accuracy of the workpiece. During use, the traditional screw press will drive the push plate to move during the continuous downward pressure of the upper mold, so that the upper mold is limited and positioned through multiple push plates. However, during the use of the upper mold, the push plate and the upper mold are deformed under continuous impact, which will cause the upper mold to be displaced, so that the upper mold cannot be aligned with the lower mold on the central axis, affecting the processing effect of the workpiece. Moreover, after the workpiece is processed, there are more debris on the surface, and the staff is required to manually clean the surface of the workpiece, which makes the maintenance of the workpiece not very convenient. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, to meet actual needs, and to provide a screw press to solve the problem that in the current traditional screw press, the push plate will be driven to move during the continuous downward pressing of the upper mold, so that the upper mold is limited and positioned through multiple push plates. However, during the use of the upper mold, the push plate and the upper mold are deformed under continuous impact, which will cause the upper mold to be displaced, so that the upper mold cannot be aligned with the lower mold on the central axis, affecting the effect of processing the workpiece. Moreover, after the workpiece is processed, there are more debris on the surface, and the staff needs to manually clean the surface of the workpiece, resulting in a technical problem that the workpiece maintenance is not very convenient.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: design a screw press, including an upper mold and a lower mold, and also including:

[0006] Two connecting strips are respectively fixed on both sides of the upper mold;

[0007] A high-precision positioning mechanism is installed at the bottom ends of the two connecting strips, and the high-precision positioning mechanism includes two first infrared radiation sensors, and the two first infrared radiation sensors are installed at the bottom ends of the two connecting strips;

[0008] Circular grooves are provided on both sides of the top of the lower mold, and a second infrared radiation sensor is installed inside the circular grooves.

[0009] Preferably, a movable sleeve is fixed to one end of the connecting strip away from the upper mold, a fixed plate passes through the interior of the movable sleeve, and a device top plate and a device bottom box are fixed to upper and lower ends of the fixed plate respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model connects the strip plate, the first infrared radiation sensor and the second infrared radiation sensor, and can align the first infrared radiation sensor at the bottom of the connecting strip plate with the second infrared radiation sensor at the top of the lower mold, so that the two infrared radiation sensors can realize infrared radiation. When infrared radiation exists, it means that the upper mold and the lower mold are on the same central axis. When there is no infrared radiation between the two infrared radiation sensors, it means that the infrared radiation sensors at the upper and lower positions are misaligned, and the upper mold and the lower mold are not on the same central axis. After viewing the infrared radiation information, the staff can adjust and maintain the positions of the upper mold and the lower mold in time, thereby realizing high-precision positioning of the upper mold and the lower mold, and solving the problem that the traditional screw press will drive the push plate to move during the continuous downward pressure of the upper mold, so as to limit the upper mold through multiple push plates. However, during the use of the upper mold, the push plate and the upper mold are deformed under continuous impact, which will cause the upper mold to be displaced, thereby causing the upper mold to be unable to be aligned with the lower mold on the central axis, affecting the technical problem of the processing effect of the workpiece.

[0016] 2. The utility model can set the push plate at the bottom position of the lower mold through the combination of the electric telescopic cylinder, the push plate and the electric heating tube. After the workpiece is placed in the lower mold, the bottom of the workpiece can be supported by the push plate. When the workpiece is processed, the electric telescopic cylinder can be used to drive the push plate to move downward and drive the workpiece into the water, and the debris on the surface of the workpiece can be directly put into the water, so as to quickly process the debris on the surface of the workpiece. At the same time, electric heating tubes are also arranged on both sides of the electric telescopic cylinder, which can directly dry the workpiece after the water in the bottom box of the device is released, and can directly perform maintenance operations on the workpiece after the workpiece processing is completed, which solves the technical problem that there are a lot of debris on the surface of the workpiece after processing, and the staff needs to manually clean the surface of the workpiece, resulting in inconvenient maintenance of the workpiece.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: A screw press, see Figures 1 to 3 , including an upper mold 205 and a lower mold 2, and also including: two connecting strips 204, respectively fixed on both sides of the upper mold 205; a high-precision positioning mechanism, installed at the bottom of the two connecting strips 204, the high-precision positioning mechanism includes two first infrared radiation sensors 207, and the two first infrared radiation sensors 207 are installed at the bottom of the two connecting strips 204; circular grooves 208 are provided on both sides of the top of the lower mold 2, and second infrared radiation sensors 201 are installed inside the circular grooves 208. Since the first infrared radiation sensors 207 are provided at the bottom of the two connecting strips 204, the signals of the first infrared radiation sensors 207 and the second infrared radiation sensors 201 on the top of the lower mold 2 can be emitted during the upper and lower movement of the upper mold 205. When there is infrared radiation, it means that the upper mold 205 and the lower mold 2 are on the same central axis. When the two infrared radiations are When there is no infrared radiation from the radiation sensor, it means that the infrared radiation sensors at the upper and lower positions are misaligned, and the upper mold 205 and the lower mold 2 are not on the same central axis. After viewing the infrared radiation information, the staff can adjust and maintain the positions of the upper mold 205 and the lower mold 2 in time, thereby achieving high-precision positioning of the upper mold 205 and the lower mold 2, and solving the problem of the traditional screw press. In the process of the upper mold 205 being continuously pressed down, the push plate 301 will be driven to move, thereby limiting the positioning of the upper mold 205 through multiple push plates 301. However, during the use of the upper mold 205, the push plate 301 and the upper mold 205 are deformed under continuous impact, which will cause the upper mold 205 to be displaced, thereby causing the upper mold 205 to be unable to be aligned with the lower mold 2 on the central axis, affecting the technical problem of the processing effect of the workpiece.

[0023] For details, see Figure 1A movable sleeve 203 is fixed to one end of the connecting strip 204 away from the upper mold 205, a fixed plate 202 runs through the inside of the movable sleeve 203, and a device top plate 206 and a device bottom box 1 are respectively fixed to the upper and lower ends of the fixed plate 202. By providing the movable sleeve 203 to connect with the connecting strip 204, the connecting strip 204 and the upper mold 205 can be limited and moved, thereby assisting in positioning the upper mold 205.

[0024] For further information, see Figure 3 A first square hole 3 is provided on the top of the device bottom box 1, and a push plate 301 is inserted into the first square hole 3. An electric telescopic cylinder 302 is fixed to the bottom of the push plate 301, and the device bottom box 1 is installed at the bottom of the electric telescopic cylinder 302. The push plate 301 is set at the bottom position of the lower mold 2. After the workpiece is placed into the lower mold 2, the bottom of the workpiece can be supported by the push plate 301. When the workpiece is processed, the electric telescopic cylinder 302 can be opened to drive the push plate 301 to move downward, so that the push plate 301 drives the workpiece into the water, and the debris on the surface of the workpiece is directly put into the water, so as to quickly process the debris on the surface of the workpiece.

[0025] It is worth noting that see Figure 3 One end of the electric heating pipe 303 is fixed to the bottom of both sides of the electric telescopic cylinder 302, and the other end of the electric heating pipe 303 is fixed to the device bottom box 1. Electric heating pipes 303 are also arranged on both sides of the electric telescopic cylinder 302. After the water in the device bottom box 1 is released, the workpiece can be directly dried. After the workpiece is processed, the workpiece can be directly maintained. This solves the technical problem that there are a lot of debris on the surface of the workpiece after processing, and the staff needs to manually clean the surface of the workpiece, resulting in inconvenient maintenance of the workpiece.

[0026] It is worth noting that see Figure 3 A second square hole 304 is opened at the bottom of the lower mold 2, and the second square hole 304 is arranged corresponding to the position of the first square hole 3.

[0027] It is worth mentioning that see Figure 1 The upper and lower ends of both sides of the bottom box 1 of the device are connected with one end of the water pipe 101, and the other end of the water pipe 101 is detachably connected with a pipe cover 102.

[0028] When using a screw press, since a first infrared counter-radiation sensor 207 is provided at the bottom of the two connecting strips 204, during the process of the upper mold 205 moving up and down, the first infrared counter-radiation sensor 207 can be used to counter-radiate signals with the second infrared counter-radiation sensor 201 at the top of the lower mold 2. When there is infrared counter-radiation, it means that the upper mold 205 and the lower mold 2 are on the same central axis. When there is no infrared counter-radiation between the two infrared counter-radiation sensors, it means that the infrared counter-radiation sensors at the upper and lower positions are misaligned, and the upper mold 205 and the lower mold 2 are not on the same central axis. After viewing the infrared counter-radiation information, the staff can adjust and maintain the positions of the upper mold 205 and the lower mold 2 in time, thereby realizing high-precision positioning of the upper mold 205 and the lower mold 2. The sleeve 203 is connected to the connecting strip 204, and can limit the movement of the connecting strip 204 and the upper mold 205 to assist in positioning the upper mold 205. The push plate 301 is set at the bottom position of the lower mold 2. After the workpiece is placed into the lower mold 2, the bottom of the workpiece can be supported by the push plate 301. When the workpiece is processed, the electric telescopic cylinder 302 can be opened to drive the push plate 301 to move downward, so that the push plate 301 drives the workpiece into the water, and the debris on the surface of the workpiece is directly put into the water, so as to quickly process the debris on the surface of the workpiece. Electric heating pipes 303 are also arranged on both sides of the electric telescopic cylinder 302, which can directly dry the workpiece after the water in the bottom box 1 of the device is released, and can directly perform maintenance operations on the workpiece after the workpiece processing is completed.
