Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of clamp, concretely relates to a clamp for cleaning extrusion dewatering equipment die head. BACKGROUND

[0002] In the rubber production industry, SBS, SEBS, SIS and other production processes are increasingly mature, and domestic and foreign production devices generally use extrusion dewatering machines and expansion dryers for dewatering and drying. In the rubber production process, condensed vapor needs to add calcium chloride as a vapor dispersant, which is easy to form scale in the bore of the extruder and expander, forming solid substances such as calcium chloride or calcium carbonate, and the calcium scale falls off and blocks the die head when it reaches a certain thickness. In order to protect the equipment, avoid the water scale (calcium) that falls off from blocking the die hole of the die head, causing the equipment to run at an overpressure and damaging the equipment, the expander needs to be parked regularly to clean the die head. One of the existing methods for cleaning the die head is to clamp the die head with a hand vice or bench vice, and then use a hand drill to clean the glue. This method is low in efficiency and easy to injure the hand. SUMMARY

[0003] The utility model aims at overcoming the deficiency in the prior art, and provides a clamp for cleaning the die head of an extrusion dewatering device.

[0004] To achieve the above object, the utility model discloses a clamp for cleaning the die head of an extrusion dewatering device, which comprises a clamp main body and a clamping assembly, at least one accommodating hole and a deformation space are arranged on the clamp main body, the cross-sectional shape of the accommodating hole is matched with the cross-sectional shape of the die head so as to limit the die head in the accommodating hole, the deformation space is communicated with the accommodating hole, the clamping assembly comprises a first clamping part and a second clamping part, the first clamping part and the second clamping part are respectively abutted with two opposite faces of the clamp main body so as to deform the clamp main body towards the deformation space and abut the die head.

[0005] Preferably, the accommodating hole is provided with a plurality of accommodating holes, and the plurality of accommodating holes are arranged at intervals along the length direction of the deformation space.

[0006] Preferably, the deformation space is provided with a plurality of deformation spaces, and each deformation space is provided with the accommodating hole.

[0007] Preferably, the deformation space is provided with two deformation spaces, and the two deformation spaces are arranged in parallel.

[0008] Preferably, the deformation space is a groove penetrating through both ends of the clamp main body, and the width of the groove is smaller than the width of the accommodating hole.

[0009] Preferably, the clamp main body is provided with a through hole penetrating through both ends of the clamp main body.

[0010] The clamping assembly comprises a first locking bolt and a first nut, the first bolt passes through the through hole and is connected with the first nut.

[0015] Preferably, it also includes a second bolt and a second nut, the second bolt passing through the connecting hole and the external platform and connected to the second nut.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] When cleaning the die head of the extrusion dewatering equipment, the die head can be installed in the receiving hole of the fixture body. Since the cross-sectional shape of the receiving hole matches the cross-sectional shape of the die head, the die head can be confined within the receiving hole, thus initially fixing the die head to the fixture body. The fixture body is provided with a deformation space. The clamping assembly includes a first clamping member and a second clamping member. The first and second clamping members are respectively two sides opposite to the fixture body. The two clamping members can press against the two sides of the fixture body, causing the fixture body to deform towards the deformation space, thereby pressing against the die head and ultimately firmly fixing the die head to the fixture body.

[0018] This invention uses a fixture body to accommodate the die head, and the die head is clamped and fixed by the cooperation of the deformation space and clamping components. This ensures the effective fixation of the die head, while the entire fixture has a simple structure and low manufacturing cost. Compared with existing fixed hand vises or bench vises for clamping and fixing the die head, it avoids injury to the worker's hands. Attached Figure Description

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] A clamp for cleaning the die head of an extrusion dewatering device, see [link to relevant documentation]. Figures 1-4 The fixture includes a fixture body 10 and a clamping assembly 20. The fixture body 10 has at least one receiving hole 11 and a deformation space 12. The cross-sectional shape of the receiving hole 11 is adapted to the cross-sectional shape of the die head 30, which can confine the die head within the receiving hole 11, thereby initially fixing the die head to the fixture body 10. The deformation space 12 communicates with the receiving hole 11. The clamping assembly 20 includes a first clamping member 22 and a second clamping member 23. The first clamping member 22 and the second clamping member 23 respectively press against two opposite surfaces of the fixture body 10, thereby deforming the fixture body 10 toward the deformation space 12 to press against the die head, and finally firmly fixing the die head to the fixture body 10.

[0029] The fixture described in this embodiment accommodates the die head through the receiving hole 11 of the fixture body 10, and clamps and fixes the die head through the cooperation of the deformation space 12 and the clamping assembly 20. This ensures the effective fixation of the die head, while the entire fixture has a simple structure and low manufacturing cost. Compared with the prior art that uses a hand vise or bench vise to clamp and fix the die head, this fixture avoids injury to the worker's hands.

[0030] In this embodiment, there are multiple receiving holes 11, which are spaced apart along the length of the deformation space 12. For example... Figure 1 As shown, a deformation space 12 has two receiving holes, so that two mold heads can be fixed. Compared with the existing technology where a hand vise or bench vise can only clamp and fix one mold head at a time, this can fix more mold heads. When cleaning the mold heads, workers can clean multiple mold heads at once with a pistol, which improves cleaning efficiency.

[0031] In this embodiment, there are multiple deformation spaces 12, and each deformation space 12 is provided with multiple receiving holes 11. In this way, more mold heads can be fixed on the fixture body 10, and workers can clean more mold heads at one time, which can further improve cleaning efficiency.

[0032] like Figure 1 As shown, there are two deformation spaces 12, and each deformation space 12 is provided with two receiving holes 11.

[0033] It is understandable that the number of deformation spaces 12 and the number of receiving holes 11 can be set according to actual needs. However, in this embodiment, it is preferable to have two deformation spaces 12, which are arranged in parallel. This arrangement can improve the fixing effect of the mold head because, as Figure 1 As shown, the front and rear sides of the clamp body 10 are pressed by the first clamping member 22 and the second clamping member 23 of the clamping assembly 20, respectively. At this time, the front side of the clamp body 10 can deform towards the front deformation space 12 to press the two front mold heads, and the rear side of the clamp body 10 can deform towards the rear deformation space 12 to press the two rear mold heads, thus ensuring the fixing effect. If there are more deformation spaces 12, since the middle position of the clamp body 10 is not pressed, it will basically not deform. In this case, the fixing effect of its receiving hole 11 is worse than that of the receiving holes 11 on the front and rear sides.

[0034] In this embodiment, the deformation space 12 is a groove penetrating both ends of the clamping body 10. When the clamping assembly 20 clamps the clamping body 10, it is easier for the clamping assembly 20 to deform towards the deformation space 12, thereby clamping the die head and ensuring the die head is fixed. The width of the groove is smaller than the width of the receiving hole 11, which ensures the limiting effect of the receiving hole 11 on the die head.

[0035] In this embodiment, the clamp body 10 is provided with through holes 13 extending through both ends of the clamp body 10. Preferably, the through holes 13 are perpendicular to the deformation space 12. The clamping assembly 20 includes a first locking bolt and a first nut. The first bolt 21 passes through the through hole 13 and is connected to the first nut. By tightening the nut, the bolt head and the nut can press against the two sides of the clamp body 10, thereby deforming the clamp body 10 into the deformation space 12 and clamping the die head.

[0036] The head of the first bolt 21 and the first nut are respectively the first clamping member 22 and the second clamping member 23.

[0037] In this embodiment, the through hole 13 is located at the center of the corresponding end face.

[0038] In this embodiment, the fixture body 10 is provided with a connection hole 14, through which the fixture body 10 can be mounted on the workbench. Specifically, the fixture also includes a second bolt 15 and a second nut 16, with the second bolt 15 passing through the connection hole 14 and the external platform 40 and connecting to the second nut 16.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
