Description

Technical Field

[0001] The utility model relates to the technical field of automobile cable molds, in particular to an automobile cable extrusion device for adjusting stripping force online. Background Art

[0002] When using automotive cables, they need to be stripped and cut. If the stripping force is too large, the wire cannot be stripped and cannot be used; if the stripping force is too small, the insulation will shrink and the conductor will be exposed at the end, making it unusable. Therefore, automotive cables have a range of requirements for the stripping force, so the stripping force needs to be controlled during extrusion.

[0003] Currently, the peeling force is usually changed by adjusting the die spacing. Due to the difference in molds, the die spacing cannot be directly measured at the extruder head. When adjusting the peeling force, the die spacing can only be roughly adjusted according to the distance between the mold sleeve cover and the glue outlet, which makes it difficult to adjust the peeling force and requires multiple attempts, which not only wastes time, but also causes a lot of cost waste due to the need for continuous extrusion and measurement during the adjustment process. Utility Model Content

[0004] In view of the defects in the prior art, the utility model proposes an automobile cable extrusion device capable of adjusting the stripping force online.

[0005] The utility model is achieved in this way:

[0006] An automotive cable extrusion device for adjusting stripping force online, comprising a cable extrusion die and a die spacing measurement and display device;

[0007] The cable extrusion die comprises a die core and a matching die sleeve; the die core comprises a cable channel and a die core mouth; the die core mouth is arranged at one end of the cable channel close to the die sleeve; a first installation cavity is provided on the inclined inner wall of the cable channel close to the die core mouth, and an opening is provided at the top of the first installation cavity; the die sleeve comprises an inclined inner cavity matched with the die core, and a die sleeve mouth is provided at one end of the inclined inner cavity away from the die core; a second installation cavity is provided at the inclined inner cavity close to the die sleeve mouth, and an opening is provided at the top of the second installation cavity;

[0008] The mold spacing measurement and display device includes a mold spacing measurement device and a display device; the mold spacing measurement device includes a first distance sensor and a second distance sensor; the first distance sensor is arranged in the first installation cavity, and is used to sense the position of the mold core; the second distance sensor is arranged in the second installation cavity, and is used to sense the position of the mold sleeve;

[0009] The display device includes a display and a controller arranged in the display; the controller is respectively connected to the first and second distance sensor signals so as to receive and calculate the position data of the mold sleeve and the mold core, and finally display it on the display screen.

[0010] Furthermore, the receiver parts of the first and second distance sensors are installed opposite to each other.

[0011] Furthermore, the respective distance sensors in the first and second installation cavities are sealed by silicon carbide material with a thickness of 0.02 mm.

[0012] The utility model has the following advantages and technical effects:

[0013] The utility model configures a die spacing measurement and display device on a cable extrusion die. Without cutting off the cable production line, the die spacing can be calculated and displayed in real time through the die spacing measurement and display device. Before production, the size of the stripping force can be judged by the die spacing and pressure data on the screen. Compared with the traditional method, it is more efficient and clear and reduces the waste of raw materials.

[0014] During the production process, the changes in the mold spacing and pressure data adjusted before production are compared. If any abnormal changes occur, the machine can be stopped and adjusted in time, avoiding the situation where abnormalities occur during the production process but are not discovered, and the product is unqualified after the test is completed.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model. DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail in combination with the embodiments below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] like Figure 1 , 2As shown, the utility model discloses an automotive cable extrusion device for adjusting the stripping force online, comprising a cable extrusion die and a die spacing measurement and display device; the cable extrusion die comprises a die core 1 and a matching die sleeve 2; the die core 1 comprises a cable channel 1-1 and a die core mouth 1-2; the cable channel 1-1 is an inclined channel which gradually shrinks from the outside to the inside, and the cylindrical die core mouth 1-2 is arranged at one end of the cable channel 1-1 close to the die sleeve 2; a first installation cavity 1-3 is opened on the inclined inner wall of the cable channel 1-1 near the die core mouth 1-2, and an opening is arranged at the top of the first installation cavity 1-3; the die sleeve 2 comprises an inclined inner cavity 2-1 which cooperates with the die core 1, and a cylindrical die sleeve mouth 2-2 is arranged at one end of the inclined inner cavity 2-1 away from the die core 1; a second installation cavity 2-3 is arranged at a position of the inclined inner cavity 2-1 close to the die sleeve mouth 2-2, and an opening is arranged at the top of the second installation cavity 2-3.

[0022] The mold spacing measurement and display device includes a mold spacing measurement device and a display device; the mold spacing measurement device includes a first distance sensor 3 and a second distance sensor 4; the first distance sensor 3 is arranged in the first installation cavity 1-3, and is used to sense the position of the mold core 1; the second distance sensor 4 is arranged in the second installation cavity 2-3, and is used to sense the position of the mold sleeve 2; the two distance sensors transmit data to the display device, and the display device calculates the data to obtain the mold spacing; the receiver parts of the two distance sensors are installed opposite to each other.

[0023] Preferably, the respective distance sensors are sealed in the first and second installation cavities 2-3 by silicon carbide material with a thickness of 0.02 mm. Since the hardness of silicon carbide material is high enough and its structural shape will not change until it reaches at least 2000°C, the use of the sensor will not be affected even if the extrusion temperature is very high. Moreover, silicon carbide material is non-metallic and will not affect the magnetic field of the sensor, so the distance between the modules obtained by measurement and calculation is still accurate.

[0024] The display device includes a display 5 and a controller arranged in the display 5; the controller is respectively connected to the first and second distance sensors 4 signals so as to receive the position data between the mold sleeve 2 and the mold core 1 for calculation, and finally display the mold spacing and pressure on the display screen. Under the action of the relevant data of the mold spacing, pressure and peeling force, the mold spacing can be accurately and quickly adjusted to ensure that the cable peeling force meets the technical requirements. Compared with the traditional method of adjusting the cable peeling force without a mold spacing measuring device, this device can not only improve the efficiency but also reduce the cost loss in the process of adjusting the peeling force. At the same time, it can determine the process according to the mold spacing data of the extrusion production of cables of different specifications to ensure the stability of the cable peeling force.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
